Many of these schools are located in Nanjing, Zhengzhou and other places, many of which are 985 and 211 universities with students all over the country.

The details hide the temperature of the service and are also connected with the trust of the masses.

In the next step, Liaocheng Social Insurance Center will continue to carry out the activity of "Young People Who are Pro-social Security", and promote young cadres to practice the concept of "Pro-social Security" in depth through sharing, and integrate the service concept into every specific handling, so as to achieve a high degree of standing, deep understanding, temperature service, scale implementation and accurate results, create extraordinary achievements in ordinary posts, and continuously improve the people’s sense of gain and happiness in social security services.

　　PHEV (plug-in hybrid vehicle) has attracted much attention because it can enjoy the policy of licensing and tax exemption in some areas. Compared with transmission hybrid vehicles, PHEV has a larger battery capacity, and can run in pure electric mode. When the battery is exhausted, it can continue to run on its own internal combustion engine power. Many people travel in cities in pure electric mode and switch to fuel mode at a long distance. The advantage of this is to reduce the cost of vehicles and improve the cruising range without worrying about the cruising range.

　　Recently, car companies have also launched many PHEV models. Next, I will show you several new cars recently launched, which are good in terms of purchase feasibility, economy and practicality.

Wen | No.7 (Luosi Film and Television Research Group)

"The world is very big and keeps walking. If the body can’t arrive, let the taste buds start first. " On the days when we can’t travel far, there is a program that takes a different approach tonight, starting from the embassy in China and starting the "journey of global discovery" on the tip of the tongue. It is the first domestic ambassador’s food creative reality show "Ambassador’s Kitchen" jointly produced by Jiangsu Satellite TV, World Wide Web, Beijing Qiaoyi and Mango TV.

The first stop of the program came to the Argentine Embassy in China. A "food study team" composed of six people, including Jerry Lee, Chun Wu, He Chaolian, Liu Wei, Sun and Boogie, tasted the cooked food and felt the unique cultural charm of Argentina.

The delicacies in and out of the embassy are condensed into the crystallization of cross-cultural communication. The Ambassador’s Kitchen explores the new variety mode of "food+",and under the framework of "food+literature tour+reality show", it has made a "creative fusion dish" where Chinese and foreign food meets the moon and different civilizations blend.

"The Ambassador’s Kitchen" is broadcast on Jiangsu Satellite TV at 21:10 every Sunday and simultaneously launched on Mango TV at 21:40 every Sunday. On the night of the premiere, topics such as # Jerry Lee Chun Wu Sun knows how to cooperate in cooking #, # Sun’s reaction to Liu Wei’s serving in Boogie #, # Boogie Liu Wei’s performance showed a dish by the way #, # Ambassador’s kitchen staff wanted to start broadcasting # boarded the hot search in Weibo, and many viewers called it the international "variety show", "Enjoy the best with the World Cup!"

"Fresh" flavor opening:

It’s the first time to "treasure hunt" in the embassy.

Painted cow sculptures, Diego Maradona jerseys, malbec, Argentina’s national treasure wine variety, and the poster of Argentina’s first film "The Thief" released in China Mainland … Following the footsteps of the "Food Study Team", the mysterious Argentine Embassy in China was "opened" on the screen for the first time, and the novelty came to me. Like Jerry Lee, Chun Wu, He Chaolian and other guests, most of the audience visited and felt the embassy in China for the first time at zero distance, and could not help but exclaim: "So the ambassador curator is like this!"

Follow the program to visit the Argentine Embassy in China.

According to the program setting, the "food study team" is divided into two teams. They will obtain the "food code" of various countries through cultural interaction, food tasting and other links. They will not only reproduce the special dishes, but also combine the "food code" with China cuisine to innovate and develop new dishes that are integrated with China and foreign countries. If the new dishes are favored by the embassy, they can join the "global food menu".

With the theme of "ambassador’s kitchen", the program is not limited to food, but to explore and discover the rich cultural imprint in the embassy and carry out international cultural exchanges. "Where did the tango originate?" "Which instrument is called the soul of tango?" The guests were still immersed in the dance steps of the traditional slow-paced tango in Argentina one second, and the next second they entered the answering session. These interesting questions and answers inadvertently made the guests and the audience get the knowledge of tango. Sabino Vaca Narvaja, Ambassador of Argentina to China, personally demonstrated the brewing method of "yerba mate". From all kinds of tea leaves and teapots to straws with built-in springs, the guests and audience got a deep understanding of this unique Argentine national treasure.

Argentine Ambassador to China Niu Wangdao brewed yerba mate.

When "hard knowledge" softens in a way that you like to see and hear, the overall expression of the program is also smooth and brisk. The broad charm of foreign culture is condensed into the square inch of the embassy, and the "Ambassador’s Kitchen" with a "fresh" taste has firmly grasped the attention of the audience.

The taste of "fun" beats:

Time-limited re-enactment of special dishes, taste buds dancing

As the saying goes, "Food is the most important thing for the people". From the east to the west, from the coast to the inland, from the plains to the mountains, different natural environments have given birth to different food cultures. To understand a country, food is undoubtedly the best way and the most intuitive window. Compared with Japanese food, Korean food and Thai food familiar to Chinese people, Argentine food is relatively small, which also arouses the public’s curiosity-what do Argentines like to eat?

A "special affection" white wine with strong rose fragrance and musk, a roasted jiaozi mixed with lavender fragrance and butter fragrance, a roasted Angus eye meat heart that retains the true taste of beef, and a stewed beef with Giso lentils and a Milani sauce with Nabo beef condensed with Argentine food wisdom … Niu Wangdao, the Argentine ambassador to China, came to an Argentine steakhouse with a "food study team", and the authentic dishes carefully cooked by authentic chefs were enough to make the taste buds dance and bloom.

Argentina special food

"Argentines like salty dishes, but they are not interested in spicy things" "Argentines don’t need heavy ingredients, and they like the authentic taste of real things best" "Argentines like to eat meat, but the feet and heads of animals hardly appear on their dining tables" … With the announcement of the "food code", it not only digs into the depths of food culture, but also arouses the interest of the audience. After the program was broadcast, many diners launched "radar" to search for Argentine restaurants around them.

The re-enactment of food is the highlight of the Ambassador’s Kitchen. According to the saying "I have eaten more salt than you have eaten rice", the "high salt value team" consists of Jerry Lee, Chun Wu and Sun, and the "low salt value team" consists of He Chaolian, Liu Wei and Boogie. Some of them are cooks, and some are experts in cooking. They need to re-create four dishes in 90 minutes, which will be evaluated by overseas Chinese and friends in Argentina.

Guest replica dishes

The whole process can be described as a pot of stewed beef cooked dry in Chun Wu-in full swing. As a reality show part of the program, it not only has a full sense of competition, but also brings the audience a relaxed, healing and interesting sense of entertainment. At the same time, the re-enactment process of the two teams is also a kitchen teaching, returning to the life service function of traditional food variety shows, attracting many food lovers to "get ready".

"Jane" tastes into the heart:

Friendship spans thousands of waters in Qian Shan, and food has no borders.

Argentina is the farthest country from China, right behind China on the earth. No matter which direction you go to Argentina, the distance is about 20,000 kilometers. Two countries so far away, nurtured by different civilizations, have the idea of empathy.

It is not difficult to find that the Argentine national cuisine presented in the program has something in common with China cuisine: roasted jiaozi is quite like our leek box, stewed beef with lentils and stewed beef brisket with radish, which represents the taste of home, and sweet fried dough sticks are also the breakfast choice of Argentines … Different food producing areas, different cooking techniques and different cultural heritages are similar to crossing thousands of waters in Qian Shan. And this distant similarity is probably another expression of "food without borders".

"Journey of Global Discovery" on the Tip of the Tongue

"We realize the life, preferences and even personalities of people from different countries, and we can make friends through food, and food is also a bridge for communication." As guest Boogie said, "The Ambassador’s Kitchen" builds a bridge of delicacies, and the world’s delicacies evoke cultural curiosity, which also leads to the friendship between mountains and seas.

This year marks the 50th anniversary of the establishment of diplomatic relations between China and Arab countries, and it is also the year of China-Arab friendship and cooperation in 2022. At the same time, it is the 10th anniversary of the establishment of diplomatic relations between China and many countries. It is an important opportunity for China to consolidate traditional friendship with other countries, deepen cooperation space and promote integrated development. Today, with China stepping onto the world stage with a more open, confident and proactive attitude, it is of far-reaching significance to launch this file "Ambassador’s Kitchen".

Gourmet without borders

On the one hand, the program symbolizes the communication between people and the blending of feelings, vividly conveying the spirit of hospitality and frankness of people from different countries; On the other hand, it is a beneficial exploration for media diplomacy to promote "goodwill communication" by telling the story of China in the language of food without borders and giving full play to the advantages of variety shows in mass communication with strong affinity and wide radiation.

Next, The Ambassador’s Kitchen will also visit the embassies of New Zealand, Thailand, Turkey, Ireland, Iceland and other countries in China. Envoys are the letter, food is the bridge, and hand in hand. I believe that with the broadcast of the program, the colorful collisions of different countries, cultures and customs will continue to show the international friendship between the United States and the United States.

　　[Pacific Auto Network New Car Channel] There are not many news that can grab the headlines of Guangzhou Auto Show in the past two weeks. Apart from supermodel wrestling, there is only one electric car that can break 100 in 2 seconds and instantly lose all super-running: a new generation of Tesla Roadster.

　　In the past, many car fans were dismissive of electric cars that claimed to subvert the traditional automobile industry, because in the eyes of our internal combustion engine party, nothing is a car without an internal combustion engine, only an internal combustion engine is fun and has the strongest performance. But now, the acceleration time of the new generation Tesla Roadster in two seconds has made the internal combustion engine party have to re-examine the electric car.

　　Tesla Roadster broke 100 achievements and over 10,000 torques in 2 seconds, which we will explain later. First, let’s take a look at how to buy this outrageous electric car.

Direct link to book a car: Tesla China official website

　　The new generation was officially released at the Tesla Design Center in Hawthorne, California last week. The new car will be delivered in 2020 and has been pre-sold overseas. Judging from the booking amount of 1.33-1.659 million in China District, Tesla is ready to let China buyers "Book the car in full+wait for three years”。 Of course, the final price of Roadster in China will be higher than that in the United States. After all, taxes and fees have not been calculated yet.

　　P.S.　

　　1, Base (basic version)The booking fees at home and abroad are different.

　　2. Please note that even if the full amount is paid, it is only "book",not"schedule”； (The deposit does not have the nature of debt guarantee. If the party receiving the deposit breaches the contract, it only needs to return the deposit it has received without double payment. )

　　3. The Founders Series is limited to 1,000 vehicles. The "sincerity gold" in the United States is the quotation itself. It can be seen that this series is more like a crowdfunding game … …

　　4. Musk announced on Twitter yesterday that completing 0-96km/h in 1.9 seconds is onlyBaseThe performance index of,Founders Series will be more lethal.

　　1.33 million three-year zero interest and zero income to Tesla is to become the first person in this area who can be forced by Tesla sports cars after mass production. We can’t guess the idea of local tyrants. So even if you pay 1.33 million to book a car, can you guarantee that Roadster will be mentioned in three years?

　　With today’s Model 3 as a lesson, I am afraid that local tyrants may not be able to pick up their cars with peace of mind after three years. Tesla’s third-quarter financial report shows that Tesla has only delivered 222 Model 3s, which is far from Musk’s previous claim of delivering 500 models per week.

　　The low production capacity is because the automatic production line of Panasonic, the supplier of power batteries, is not ready yet, which leads to low battery output, which further limits the output of Model 3. Tesla had hoped to produce about 1,500 Model 3 vehicles in the third quarter of this year, but only 260 vehicles were produced. It can be seen that Tesla has already encountered a serious productivity hell.

　　Tesla Model 3′ s capacity crisis has not yet been resolved. Compared with working day and night in the California factory, Musk slipped out of a supercar with exploded parameters.

　　Because Tesla needs money too much, it is necessary to release a new car at this juncture, even if it is not for direct cash flow, raising the price-earnings ratio and boosting the confidence of the capital market. Just looking at the choice of time nodes, Musk is a master of capital.

　　Whether it is Model 3 or today’s new Roadster, Tesla has made products into futures, and released the final product in the form of a prototype three years later. You know, not to mention other high-return investments, even if you put 1.33 million in the bank for regular three years, you can earn at least 200,000 to 300,000, which is equivalent to raising the price in disguise. Whether it is a loss or a gain, only the customer who made the deposit knows.

　　Tesla’s crazy burning of money is worrying Wall Street. According to relevant news, it has obtained more than $3 billion in funds through various channels such as stocks, convertible bonds and bond issuance this year, and it has burned $2.6 billion in the past two quarters alone. It is precisely because of the shortage of funds that Musk hopes to bring new funds to it by issuing bonds.

　　In the fourth quarter, Tesla is expected to invest $1 billion; As of the end of last quarter, Tesla still had 3.5 billion yuan (total cash+cash equivalents). Analysts predict that by the end of the first quarter of next year, Tesla’s book may be only about $1 billion. In order to maintain normal operation, Tesla needs to raise another $2.5 billion to $3 billion.

　　As soon as the launch of the new car at the Tesla Design Center in Hawthorne, California, the mainstream voice of the media was pursuing trucks and the new Roadster. Today, Tesla’s share price has risen from the lowest of $299 when Q3′ s financial report was released to $308.74 (closing price on November 20th), but it has dropped by nearly 21% compared with the all-time high of $389.61 on September 18th.

　　Although Tesla’s electric semi-trailer trucks and the second-generation Roadster have both appeared, investors are still worried about whether Model 3 can successfully complete the mass production target.

　　At present, the market has a broad prospect, but the competitors will not lag behind Tesla in terms of technical ability and capital. Once Tesla’s cash flow continues to deteriorate, it is doubtful whether it can guarantee the current development status.

　　It’s good news that Tesla set up its own factory in China. Musk also made it clear in a conference call that he would not make capital expenditure on China before 2019. Although Tesla is very likely to set up a factory in China independently, it can’t hydrolyze the thirst. At present, the capacity problem of Model 3 is still severe, and the cash flow is further deteriorating.

　　Now it is said that the market share of that windows8 system has risen the fastest, and that it is the win8 system. More and more people install win8 system after being recognized by the market.

?　　Foreword　　

In 1993, Belgian scientists discovered a new antibody-nano-antibody (VHHs) in camel serum, which is different from the traditional antibody structure and only consists of heavy chain variable regions. Compared with traditional antibodies, nano-antibodies have the advantages of stable physical and chemical properties, low immunogenicity, strong tissue permeability, and can recognize epitopes that traditional antibodies cannot recognize, which makes them a strong and beneficial supplement to traditional antibodies.

Nano-antibody is only composed of heavy chain variable region, with small molecular weight and simple structure, which enables it to realize stable expression in various expression systems. So far, VHHs has been expressed in many expression systems, from prokaryotic cells, yeast, fungi, insect cells, mammalian cell lines to plants. This paper mainly introduces the expression of nano-antibody in different expression systems, and the present situation and development trend in the field of this system.

Prokaryotic expression system　Prokaryotic expression system is the earliest mature protein expression system studied. Obtaining foreign proteins through prokaryotes can obtain gene expression products in a short time, and the cost required is relatively low. The expression system mainly includes Escherichia coli expression, Bacillus subtilis expression and Streptomyces expression. Among them, Escherichia coli system is the most widely used, and the prokaryotic system generally refers to the expression of Escherichia coli.

Escherichia coli expression system　Escherichia coli expression system is the most important expression platform of recombinant protein in laboratory environment, and the expression is controlled by lactose operon. The host of Escherichia coli system has the advantages of fast growth, simple culture, low price, clear genetic background and high protein expression. However, it can not modify the expression product after translation, and the expression product contains a lot of endotoxin and is easy to form inclusion bodies.

Common host bacteria of Escherichia coli expression system

Periplasmic space, as the only compartment with oxidation environment in Escherichia coli, is the most commonly used expression system of nano-antibodies containing specific disulfide bonds. In addition to aerobic environment, there are many partners and isomerases in the periplasmic space, which can promote the correct formation of disulfide bonds and help protein fold. Nano-antibody protein is first produced in the cytoplasmic space, and then secreted into the periplasmic space through Sec pathway, SPR pathway or Tat pathway. After signal peptide is removed by signal peptidase, the target protein can be obtained [1].

Up to now, many VHHs have been successfully expressed in periplasm, some of which can reach tens of milligrams per liter, but there are still a lot of VHHs with low yield. This is because many fusion proteins can not be effectively secreted in the periplasmic space, and cytoplasmic expression seems to be the only expression mode of such fusion proteins [8].

The cytoplasm is a reduced compartment, so that the proteins expressed through the cytoplasm can not be folded correctly, and most of them are inclusion body proteins. The proteins are protected from the degradation of intracellular enzymes and are easy to be separated in high purity and concentration. However, there are many kinds of proteins in cytoplasm, and it is difficult to purify them. At the same time, nonfunctional inclusion proteins need to be completely denatured and refolded to be recovered from these inclusions, but the recovery of VHHs is usually inefficient [1]. In order to solve the problem of cytoplasmic expression, Xue X and others designed a new dialysis-dilution device in 2016. Using this device, researchers refolded VHHs and achieved a recovery rate of 85%, while the conventional dialysis and dilution methods only reached 13%[9]. Bacterial cytoplasm can be an effective compartment to produce correctly folded nanoparticles when expressed by recombinant vectors with sulfhydryl oxidase and disulfide isomerase activities. Larger volume and wider cytoplasm of chaperone/folding enzyme can achieve high yield of nano-antibody [6]. At the same time, double mutants with defects in thioredoxin and glutathione pathways have been developed. Some of these strains have been sold commercially in recent years, such as Origami (Novagen), Rosetta-gami (Novagen) and SHuffle?T7 (New England Biolabs) [10]. Among them, Shufflet 7 overexpresses a critical periplasmic isomerase DsbC, which can effectively catalyze the isomerization of disulfide bonds. Some studies have found that,The activity of isomerase DsbC can increase the yield of functional recombinant protein in periplasmic research [11].　　

Kavousipour Soudabeh and other modified vectors added four different signal peptide sequences to guide the secretion and expression of nano-antibodies, and found that TrBC signal peptide had the best effect [5]. Jianli Yu et al. used repetitive amino acid sequence motifs (GAGAGS) found in silk fibroin (SFP) as a new fusion tag (SF-tag) to enhance the expression of nanosomes in E.coli.. The transcription level of labeled protein is 2.3-7.0 times that of unlabeled protein, and the yield is increased by 2.5-7.1 times [27]. Xi Xie and others tried to select antifreeze protein AXX, and obtained its reverse transcription protein XXA by synthesizing XXA gene, which was used to develop new soluble fusion tags. It was found that the solubility ratio of fusion protein expressed by XXA fusion tag reached 86%, which was much higher than that of other tags [12].

Other prokaryotic expression systems　Lactic acid bacteria are the most common intestinal probiotics, which are generally considered to be harmless to human body and are very suitable for the production host of therapeutic molecules. However, the existing expression data show that the yield of VHHS produced by lactic acid bacteria is low, about 1-3mg/L, which is much lower than that of Escherichia coli [13,14]. Lactobacillus rhamnosus DSM14870, as a normal flora in human vagina, can express HIV antibody in the form of soluble or cell wall anchor fixation, and is a suitable expression host for HIV antibody [2]. When Bacillus brevis choshinensis was used for 3L fed-batch fermentation, the yield was as high as 3g/L[15]. This system is easy to manipulate genes, has no endotoxin and shows weak protease activity, so it is a very noteworthy system.

Eukaryotic expression system　

Due to the defects of prokaryotic expression system, such as difficult purification of inclusion body protein and incomplete protein modification, people began to use eukaryotic expression system to study genes. At present, eukaryotic expression systems commonly used in genetic engineering research include yeast expression system, insect cell expression system and mammalian cell expression system.

Yeast expression system　Yeast system has clear genetic background, simple operation, easy genetic operation, perfect eukaryotic protein expression control system and advantages of both prokaryotic and eukaryotic expression systems. Yeast eukaryotic protein expression systems include methanol yeast expression system, Saccharomyces cerevisiae expression system, Schizosaccharomyces expression system and Kluyveromyces expression system [17].

Saccharomyces cerevisiae is the first yeast fermented by human beings, which has no specific virus and low cost. At present, it is the largest yeast expression system in shake flask culture, with the output exceeding 100mg/L[16]. Some amino acids in VHHs can participate in the recruitment of molecular chaperones in endoplasmic reticulum, thus narrowing the difference of molecular chaperones between Saccharomyces cerevisiae and mammalian cells, which is beneficial to the folding kinetics of nano-antibodies and improving the yield of nano-antibodies in Saccharomyces cerevisiae [17]. The protein expressed by Saccharomyces cerevisiae is prone to hyperglycosylation, and a large number of endogenous proteins are produced during fermentation, so the secretion efficiency of the target protein is low [1]. Considering the above problems, Saccharomyces cerevisiae is gradually replaced by methanol yeast represented by Pichia pastoris.

Pichia pastoris expression system is an efficient expression system of foreign proteins. This microorganism does not accumulate toxic ethanol, but only secretes a few endogenous proteins, and its glycosylation degree is the same as that of mammalian cells, so its immunogenicity is weak, so it is the most commonly used eukaryotic expression system. Pichia pastoris has a strictly regulated methanol inducible AOX1 promoter, which is suitable for high expression of foreign proteins [1]. But methanol is a highly toxic and dangerous chemical product. The GAP promoter without methanol induction is used instead of AXOI, and the carbon source does not need to be changed during the culture process, so the operation is simpler and the time for foreign proteins to reach the peak level can be shortened. The yield and affinity of nanoparticles produced by this system are similar to those produced by methanol-induced expression. It has been studied that the yield of nano-antibody expressed by this system in shake flask is 51.71mg/L[18] and 16mg/L[19].

Fungal expression system　

Some filamentous fungi, such as Trichoderma and Aspergillus, can secrete a large number of foreign proteins in the culture medium. However, the fungal system not only expresses protein of interest, but also produces many proteases, which affects the yield. Joosten et al. obtained only 1.5 mg/L VHHs in Aspergillus awamori medium. After adding 0.25% BSA, it reached 7 mg/L. It is reported that more than 80% of VHH is degraded or adhered to the cell wall compared with endogenous xylanase secreted efficiently in this system, and researchers believe that the low secretion efficiency of VHHs is the bottleneck of fungal expression [20]. In order to overcome this limitation and protect VHHs from degradation, other researchers fused VHH with the high amylase A signal sequence (sTAA) of Rhizopus oryzae lipase (N28) and the N-terminal 28 amino acid fragment (N28), so that the highest yield of VHHs expressed in Aspergillus oryzae reached 73mg/L, which was 300-800 mg/L lower than that of Escherichia coli [21]. The final yield of GlaB-VHH fusion protein in Aspergillus oryzae can reach 610mg/L, which provides the possibility for high expression of nano-antibody, but its stability needs to be verified [22]. In addition, VHH[23] was expressed by maize head smut in unconventional secretion pathway.

Insect cell expression system　

Insect cells are a widely used eukaryotic expression system, and recombinant baculovirus vectors (such as AcMNPV) can specifically transfect insect cells. Its survival in nature is short, and the strong promoter is inactivated in mammals and cannot infect vertebrates, so the recombinant baculovirus is safe for human beings. Proteins with complex structures under the control of strong promoters may not be able to form correct folding and post-translation modification, which may lead to the aggregation of target proteins and reduce antibody production, so the expression yield of VHHs in this system is much higher than that of other types of antibodies [17].

Gómez-Sebastián and others used the improved baculovirus expression system (IBES? technology) to express VHHs for the first time. The chigger larvae were inoculated with different recombinant baculovirus inoculation methods. The yield of VHH extracted from larvae is 257 mg/L, and the recovery rate after purification is 50%[7]. When expressing anti-endothelial cell selection protein, Drosophila cell SC-2 secreted 12-14mg/L, but the target protein was not detected when expressed in Escherichia coli at the same time, which may be related to the processing and modification ability of insect cells [26].

Mammalian cell expression system　Mammalian cells are the best expression system for therapeutic antibodies, because the produced antibodies have the weakest immunogenicity. At present, the main cell lines include CHO, NS0, Sp2/0, HEK293 and per C6 [17]. Among them, CHO cells grow rapidly and adapt to serum-free suspension culture, which is the most popular host. They can express VHHS up to 100mg/L in shake flask [24]. HEK293 cells are more commonly used in the laboratory because of transient transfection and semi-stable expression, because they require less time and labor. However, monoclonal antibodies approved for the treatment of human diseases are only produced by CHO, NS0 and SP2/0. So far, HEK293 cells have not been used to produce VHHs, and there are few reports about producing antibody fragments by this method [17]. In most literatures, CHO is used to produce antibody fragments. Up to now, 50% of the therapeutic proteins produced in industry are still produced by CHO [1]. The production costs associated with mammalian cell lines are much higher than those associated with any other laboratory research platform.

Common host cells of mammalian expression system

Plant expression system　Compared with other expression systems, plant production platform (stable and transient expression system) is cheap, safe, capable of folding and assembling complex proteins and post-translation modification, easy to expand, and unaffected by human pathogens and diseases. It is an ideal protein expression host and is usually used as an alternative method for mammalian expression systems. In addition, plant expression products can be concentrated in specific organs, such as leaves or seeds, and can be taken orally directly. Tobacco leaves are the most common hosts for expressing VHHs, while the proteins expressed in Arabidopsis and rice seeds have attracted much attention because of their direct oral input of VHHs[1]. The stable transformation methods commonly used in plant system expression have some problems, such as the recombinant gene escaping to nature or the time-consuming transformation. Therefore, some studies have proposed the transient expression system of plant virus expression vector as an alternative method, and the nano-body content with correct conformation reaches 0.45% of the total soluble protein [25].

Present situation and development of nano-antibody expression　

Escherichia coli expression system is the most commonly used expression system of nano-antibody, which has two expression modes: periplasmic expression and cytoplasmic expression, each with its own advantages and disadvantages. Some oxidation engineering strains have been modified, but more experimental support is needed. In addition, various methods of modifying vectors, such as adding labels or signal peptides, have been put forward and have been verified by experiments. Compared with Escherichia coli, Pichia pastoris has excessive glycosylation, which may lead to immunogenicity and ultimately affect its clinical application. The expression systems of fungi, insects, plants and mammals are much more complicated than prokaryotic and eukaryotic expression systems, and are generally not easily adopted after considering the production time, cost and laboratory conditions.

Escherichia coli system is fast, convenient and cheap, and it is the first choice for VHH expression under most laboratory conditions. When some types of VHHs can’t be successfully produced in E.coli, other systems will be used instead.

　　【 Different opinions 】

　　Recently, in order to comply with the audience’s opinions and meet the audience’s expectations, the "changing while broadcasting" that timely modifies the relevant content according to the audience’s feedback and public opinion calls during the broadcast process has become a new operation mode of drama series in video website communication. From "Do you know whether it should be green, fat, red and thin" to "slow-motion play" in the new edition of "Eternal Dragon Slayer", there are various forms of expression. This rapid response mechanism is being used by more and more drama producers after achieving some visible communication effects, and has won many praises from the industry and the audience.

　　For creators and communicators, the behavior of "changing while broadcasting" represents the communication concept of respecting the audience, and also shows the creative attitude of being pragmatic and striving for perfection. Compared with those practitioners who regard film and television creation as a "one-shot deal", who know that there is a mistake but don’t admit it, or even face criticism and questioning, the behavior of knowing the mistake and correcting it in time is worth encouraging. However, this kind of "after-sales service" is, after all, a new phenomenon of production and broadcasting emerging in the process of rapid development of the industry. Most viewers don’t know much about it, and its operating mechanism is not perfect, so there are still some possible negative factors hidden in the actual operation process, which need to be vigilant. On the one hand, this model will subtly encourage the creator’s luck, that is, "it doesn’t matter if it is casual and rough in the original creation, even if there is an error, there is still room for revision in the broadcast process." Once such a psychological formula is formed, it will undoubtedly do harm to the development of the industry. On the other hand, respecting the audience does not mean blindly satisfying and catering. The audience can design whatever bridge they want to see and arrange whatever ending they want. In fact, it is an irresponsible cramming creation. Regardless of the ideological theme or aesthetic taste, the audience needs more guidance, and there is no need to say anything about it. In most cases, the forced temporary modification behavior in the process of broadcasting is a last resort.And is not a conventional operation mode. Creators should feel guilty about the lack of rigor and thoughtfulness when they started, and learn from it, so as to make it happen again. This must not be used as an excuse and retreat for inferior creation. And those so-called "at the request of the audience" to modify the fate of the characters and the ending of the story are even more cautious. After all, literary and artistic creation that appeals to people’s hearts is serious. If it caters to or even condescends to the tastes of some audiences at the expense of distorting the original intention of creation, in essence, it will make commercial benefits overshadow social benefits and abandon the basics.

　　In addition, there is a more dangerous business appeal to be vigilant. The producers of individual dramas know that their works have serious injuries and "slots", so they not only broadcast them directly without modification, but also hype these issues as gimmicks to generate public opinion topics to achieve the purpose of attracting attention. Then, we made a big fuss about the "after-sales service" while broadcasting, to show the film’s "attitude of admitting mistakes" and "speed of correcting mistakes", so that the audience could feel the satisfaction of being valued, and they seemed to enjoy a high-level drama-watching experience with high participation and strong interaction. This behavior takes the mode of "changing while broadcasting" as a marketing means and commercial trick to capture the audience, which makes the creation and dissemination of works taste worse and worse.

　　As far as the operation mode of "modifying while broadcasting" is concerned, domestic dramas are still in the primary stage of "correcting mistakes and filling gaps", while some countries with mature TV drama industry such as Europe, America, Japan and South Korea have already realized the operation paradigm of "writing, filming, broadcasting and modifying while broadcasting". In recent years, an interactive creative mode known for immersion and interactivity has become popular in the industry. This kind of work can be regarded as a mixture of watching and participating. It tries to give full play to the dynamic role of the audience, so that they can make choices at some key nodes in the process of watching, thus having strong control over the role decision in the work, and finally determining the plot development and the fate of the characters in the drama. Although all these measures are more rigorous and mature compared with the "broadcast while changing" mode, they fully integrate the wisdom of the audience into the drama creation, so that the works can basically keep pace with the market demand, but they have not fundamentally solved the disadvantages and hidden dangers of the "broadcast while changing" mode. If the operation paradigm of "writing, filming, broadcasting and changing" and interactive works become the possible development trend of China drama production and broadcasting in the future, then relevant practitioners need to keep a calm, rational and prudent attitude towards them and guard against their dislocation and deviation in practice.

　　Creators and communicators should at least be soberly aware of the following points: First, the original intention of "modifying while broadcasting" should not only be positioned at the omissions and deficiencies in the process of modifying and creating, but should achieve the balance between audience satisfaction and market ratings through deeper communication and reception interaction; Secondly, we should prevent the phenomenon of catering to the audience’s tastes to the neglect of the establishment of positive values and the original aesthetic style and artistic characteristics of the works, and grasp the degree of satisfaction and guidance under the principle of "social benefit first"; Third, the ultimate goal of "broadcasting while changing" is not to attract eyeballs to earn money, but to create a benign environment for full communication with the audience, to maximize the audience’s wisdom to bless the quality improvement of the drama, and to make the works more artistic vitality and market communication; Fourthly, we should devote ourselves to constructing a long-term mechanism of self-improvement and self-transcendence of drama series, so that the works can continuously gain the internal drive to the road of quality products in different links of creation and communication, and help the whole industry to mature and prosper.

　　(Author: Yan Wei, director and editor of China Television Arts Committee)

　　China Overseas Chinese Network July 27th According to the report of Spain’s Oulang. com, the Spanish Chinese 100-yuan store food stores are facing competition from a large number of small supermarkets, but at the same time, many Chinese have changed their careers and directly joined the chain operation to become the owners of small supermarkets. The large number of small supermarkets has attracted the attention of statistical agencies.

　　According to "american retail", there were 550 small supermarkets opened in Spain last year, most of which were small fast-selling supermarkets under big chain brands, such as Carrefour Express. This is closely related to the change of residents’ consumption habits. More and more people advocate fast, which provides a market for small supermarkets in residential areas.

　　"Spaniards are gradually giving up going to traditional markets and large supermarkets in the suburbs, but choosing online shopping or small supermarkets in residential areas." In the past ten years, this supermarket revolution has been replaced unconsciously. However, the origin of all the changes starts from 2009. From that year, the commercial law changed, it became easier to open a small convenience supermarket, and the government also encouraged the development of small commodity trade. In 2013, the People’s Party government at that time passed the Business Freedom Emergency Act, which once again contributed to the opening of such commercial supermarkets. Subsequently, chain operation rose rapidly, and in 2017, it began to enter a period of explosive growth.

　　Faced with this phenomenon, some analysts believe that small supermarkets are struggling to survive in the gap between large supermarkets and hundred-dollar stores, while others believe that this has brought crisis to Chinese hundred-dollar stores. At present, consumers are more and more interested in buying goods near their place of residence, which requires higher and higher speed of purchase. In addition, the requirements for quality have not decreased. Therefore, this is an excellent opportunity for small supermarkets. On the other hand, many small express supermarkets have become the pick-up points for online shopping and play an important role in the whole online shopping chain. (Xiaoxin)
