"Waltz - Xiao Zhang, please change the record, I just bought it yesterday. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info" Emily seemed to be calling some old friend, casual and affectionate, and after making her own opinion, she remembered to ask Chen Wenqiang, "For Mr. Chen, who has traveled to many countries, it should be no problem, it is simple, and free and comfortable." ”

"Slow down, I'll have to get used to it." Chen Wenqiang smiled bitterly and explained first, but in his heart, he felt that the overseas study tour experience he had made up was a bit exaggerated.

The word waltz, originally derived from the Old German word "walzl", means "to roll", "to rotate" or "to slide". The three-beat "pop" rhythm of the round dance has long been popular in Europe, especially in Bavaria, Germany, and Vienna, Austria.

Although the waltz has long been popular in rural areas, it has become a dance fashion for urban people for many reasons, such as social changes and artistic interest. The French Revolution and its intense influence in European countries, the rise of the Industrial Revolution and the mass emergence of the working class changed the demand for self-entertaining dance styles. The waltz, with a relaxed and natural body and a graceful and free demeanor, has become a more enjoyable way for people to enjoy themselves for a while.

The rapid popularity of the waltz was naturally opposed and hindered for various purposes. In addition to the church saying that it was immoral, uncivilized, and even vulgar and evil because of the close grip of men and women and the rapid rotation of movements, it was also regarded as a thorn in the side and a thorn in the flesh by those who used to make a living by teaching minuet and other court dances. However, the simplicity and freedom of the waltz have attracted a wide range of dancers, who often learn it after watching it for a while.

There were no dazzling lights, no playing band, but that didn't dampen Emily's enthusiasm. Chen Wenqiang was only rusty for a while, and his dance steps became light and proficient. And. The flexibility of his body and the ease of his strength made him more and more calm.

Yo-oh, Emily let out a heartfelt admiration, as if she was riding a boat with the waves, and her emotions became more and more excited. But her movements are not bad. With a crisp laugh - the laughter was low and gentle, but very pleasant, and it circled around Chen Wenqiang lightly.

More and more people are attracted to attention, and all kinds of complex emotions such as shock, shyness, and envy are revealed on their faces. At that time, in addition to the dance hall in the concession, foreigners loved to dance, and the Chinese did not know about this from time to time.

“…… It is enough to see this erotic dance with intertwined limbs and close bodies, and to see the solemn and subtle fine traditions of English women that are different from others, so badly distorted...... We believe it is our duty to remind parents. Don't send your own daughter to such a deadly plague...... We believe that it is no longer tolerated by any moral class of British society. Anyone who has ever been out at night cannot fail to see with unease the sight of our sisters and wives being grabbed by strangers, embraced at will, and jogging around a small room. ”

When the waltz was first introduced to England, many conservative Britons hated it and feared it like a tiger. The press has also done the above abuse. And the Chinese at that time should be more conservative, and these intellectual youth are no exception.

Kim Wanzhen's face was a little red. I don't know if it's the effect of alcohol, or if I'm a little shy, but my eyes are glued and I seem to be learning.

"Sir—that's amazing!" Wang Zhuoran swallowed hard, and even Jin Wanzhen heard the sound.

"You-" Jin Wanzhen turned her head to look at Wang Zhuoran and bit her lip lightly. said implicitly: "The music is very relaxed, do you see this dance is easy to learn?" ”

Wang Zhuoran blinked, observed carefully for a moment, and then said uncertainly: "How many more times do you have to practice?" Besides, this is a big deal—"

"It's nothing in public." Jin Wanzhen muttered with some dissatisfaction: "Don't jump with outsiders." Then feudalism is not good. ”

"Then, then I'll take a good look and study hard." Wang Zhuoran is not a fool, and he also heard the meaning of Jin Wanzhen's words.

"Well, I think the dance skills are still secondary, mainly the cooperation of the two people." Jin Wanzhen saw some ways with a woman's carefulness, and commented: "The one who dances well must take care of the other party and complement each other to be harmonious and good-looking." ”

The inner melody is indeed more important than the clever dance skills, and unfamiliar dance partners also need to be tested and run in to be harmonious, smooth and natural.

At the end of the song, Emily had not yet fully woken up from her obsession, and she began to speak in a delicate tone with a few words of German, and she couldn't stop laughing. She felt so excited that she couldn't breathe, she felt thirsty, so she walked to the sofa with Chen Wenqiang in her arms, took her cup, and drank it all in one go.

"Drink less, don't get drunk again." Chen Wenqiang kindly reminded.

Emily smiled, shook her hand indiscriminately, and sat on the sofa all of a sudden, looking at Chen Wenqiang with bright eyes that were shining with pleasure, "You dance so well, I think, you must have danced with many girls and participated in many dances." Outside of China, of course. ”

Hehe, Chen Wenqiang smiled faintly and did not give a direct answer. After a pause, he pointed to the people in the room and said, "Look, you're making such a fuss, and everyone doesn't know what to do." It's better to dance like this, let's dance again, and make the movements simpler, so that they can see clearly. Then, you teach men, I teach women, and that's how it is lively. ”

"Okay!" Emily took a drink from the guest waiter's hot plate, and as she sipped, she agreed to Chen's proposal.

……………

The cheerful atmosphere has increased again.

Chen Wenqiang and Emily demonstrated a simple dance move, without too much too fast spinning, closer to a self-entertaining dance, similar to slow walking steps and changing positions are easier for people to learn.

Subsequently, Chen Wenqiang began to invite other dance partners, and Emily pulled the shy boys off the "dance floor" one by one. In the sound of music, there are always two pairs of dancers shuttling, spinning, advancing and retreating......

Kim Wanjin began to have a little heartbeat, but soon her heart was not confused. With the rhythm of the music, swaying from side to side, and sliding feet, Chen Wenqiang's contact with her body is just right, not heavy, but can guide her from time to time. Stiffness gradually becomes natural. The feet are also closed, the hands are sometimes clasped together, sometimes apart, the eyes are sometimes lowered, sometimes they are looking at each other.

"I'm sorry, I'm sorry." Wang Zhuoran apologized repeatedly.

Emily didn't get angry and angry because she was trampled on. He put his hand back on his waist and smiled and encouraged him to continue, "Don't rush, don't be fast, walk slowly, naturally, just like walking, the direction is in your hands, and the hand holding my waist can give me instructions." Right. Don't look down, look up. ”

Chen Wenqiang can take the lead and accommodate the shyness and cowardice of girls, while Emily is more difficult. And Chen Wenqiang really didn't expect her to be so patient, so tolerant, and so enthusiastic.

It wasn't until the firecrackers outside sounded like a war that the "ball" came to an end. Judging from the movements and expressions of the crowd, although it is still a little unnatural. But it's likely that you've already fallen in love with this trendy activity.

The steaming dumplings were served, although they never stopped eating and drinking. I don't feel hungry, but this is an essential procedure for the Spring Festival, and everyone has to eat a few more or less.

Then came the real New Year's greetings, and these young people were not only Chen Wenqiang's employees, but also his students and disciples in some ways.

Chen Wenqiang smiled and accepted everyone's New Year's greetings, but found that there was one person missing. The invitation he sent out was not one-on-one, but was announced in public. Maybe it's a place for people to go for the New Year, and they don't want to come here to join in the fun, right? Chen Wenqiang was only a little puzzled, but he didn't care too much.

The party was over here, and Chen Wenqiang arranged for a carriage to send everyone back to the dormitory. The room was a mess, but it was quiet.

"There's no need to keep vigil, it's too hard, you can rest." Chen Wenqiang yawned and said to Emily.

Emily took a glass of Vermouth wine and drank it slowly, her excitement didn't seem to have completely subsided, she raised her glass to Chen Wenqiang, and said with a smile: "Good night, Mr. Chen." ”

Chen Wenqiang stared at Emily for a while, shook his head helplessly, turned upstairs, and walked to the bend of the stairs, only to hear the doorbell ringing. He frowned and walked back a little so that his eyes could just see the door.

Ah Lian opened the door, and Zhang Lunxin hurriedly walked in, looking around, looking for Chen Wenqiang.

"Zhang Lunxin, why did you arrive?" Chen Wenqiang walked down the stairs and said with a smile: "I thought you went elsewhere for the New Year......"

"Sir, they're not dead, yes, they're really not dead." Zhang Lunxin walked quickly in front of Chen Wenqiang and said to Chen Wenqiang eagerly and with some surprise.

"Don't rush, speak slowly." Chen Wenqiang smiled and patted Zhang Lunxin's arm, led him to the sofa, and motioned for him to sit down, "Okay, you have to be careful, what is the matter?" ”

……………

Historically, sulfonamides were invented from a dye called Bailangduoxi, but this drug is effective not because they are dyes, but because they contain sulfonamides, which in turn are not dyes at all. Moreover, sulfonamide is again an elusive substance, in a test tube, it is harmless to bacteria, and in the guinea pig, it kills them in large quantities, so in the human body, what happens to it?

“…… Five guinea pigs were used as a test target group, and they were each injected with streptococcus before being fed the compound. Streptococcus bacteria multiply in guinea pigs at a rate of twenty minutes, or within a few hours, the bodies of these guinea pigs are filled with this fearsome microbe. If the compound does not have a bactericidal effect, the guinea pig should die of infection within 48 hours, even if it is tenacious. Zhang Lunxin waved his hand excitedly, "But now, this group of guinea pigs is the guinea pigs that have taken compound ninety-four, and they are still alive and running around." It's, it's incredible. ”

Chen Wenqiang nodded lightly, looking at Zhang Lunxin, who was flushed with excitement, he knew that the first antibiotic drug in history might be born. Sulfonamides, a new milestone in the history of medicine.

"Sir, what does this mean, how effectively the Ninety-Four compound can protect those guinea pigs who have survived, and how a new drug against bacterial infections is about to be born, which will be a sensational event in the world and will save thousands of patients." Zhang Lunxin's eyes flashed with joy and excitement, and his tone was passionate and fast.

"Of course, this will be a sensation in the world and will be a milestone in the history of medicine." Chen Wenqiang patted Zhang Lunxin's arm vigorously, got up and came to the table, poured a glass of wine, glanced at Emily with a frown, walked back to Zhang Lunxin, handed him the wine, and said with a smile: "Come, have a glass of wine to calm down, and then let's discuss this matter seriously." ”

"Good night, gentlemen." Emily got up and said hello lazily, and staggered to her room.

The goal of pharmaceuticals is to kill pathogenic bacteria in infected humans in order to protect human health, so it is not enough to test the effect of the drug in a test tube, it must be observed in infected animals. This new perspective points in the right direction for the search for new drugs, and if the direction is right, success is not far off.

Moreover, sulfonamide is such a property, only after decomposition in the body of a living body, the resulting components have the ability to inhibit the reproduction of bacteria, but in the test tube it does not work at all.

Although I firmly believe that I will succeed, when the dawn of success appears, there is still a lot of practical work to be done. The effectiveness of the drug needs to be determined repeatedly, the tolerated dosage of the animal, and the toxic reaction after the drug overdose, etc., and it will take a long time for the new drug to be put on the market.

After seriously discussing with Zhang Lunxin for a long time and determining the future work, Chen Wenqiang personally sent the doctor who was full of enthusiasm for work out of the door, arranged his own carriage to send him back, and did not forget to give him a red envelope, or double copies.

Back in the upstairs room, Chen Wenqiang's sleepiness had disappeared without a trace, and he began to think carefully about how to get greater benefits from this new medicine.

Sulfonamides, just a general term, refer to azo compounds containing sulfonamides, that is, there are many kinds of sulfonamide-like drugs, and this discovery is just the beginning. Until penicillin is introduced, sulfonamides will be the most effective class of antibiotics. And in terms of time, it has been more than 30 years.

Is it to apply for a patent immediately after confirmation, start mass production, and make a huge profit? Or do you keep it secret, or make it in small quantities, let the world know its efficacy, and wait for the right time to have an economic and political harvest?

Chen Wenqiang is not afraid that the new drug will be imitated after it flows out, and the data such as the number of the compound and the generation process are all highly confidential, which was sorted out by Wang Zhuoran and handed over to him to be locked in the safe. According to the level of science and technology at that time, it was almost impossible to analyze and test the composition of a new drug.

Moreover, the most important thing is that Chen Wenqiang also holds the secret of the action of sulfonamides in the living body, that is, the molecular structure of sulfonamide drugs, the charge distribution is very similar to that of p-aminobenzoic acid, which affects the nucleic acid synthesis of bacteria, inhibits the growth and reproduction of bacteria, and then uses various defense functions of the body to overcome bacterial infection.

That is, sulfonamides are inhibiting, not killing. Without a clear understanding of the mechanism of the drug, it is impossible to discover and produce more and cheaper sulfonamide drugs. It's only a matter of time, but it's a matter of decades, and you can use it as a bargaining chip to get the most out of it.
