Chapter 2248: Bai Jingwu Is Back

As early as 1862, when Jingshi Tongwen Hall was opened, blackboards appeared, and now the medical practice hall of Jingshi University also uses this kind of teaching equipment. The Therapeutic Effects of Extracts on Several Common Women's Diseases" was written on the blackboard.

He has been a teacher at Tsinghua University next door for decades. He has a wealth of teaching experience.

Shen Long pointed to the charts and logic chains on the blackboard and said to the students, "Actually, this paper talks about the usage of Longjiao in women's collapse. It’s seen a lot in Pharmacopoeia; so the main content of today’s lesson is not in this paper itself.”

"It's about the scientific research method reflected in this paper, whether a medicine is effective, why it is effective, what method to use to judge, and what method to verify, this is the key point; the medical books accumulated in China for thousands of years There are countless pharmacopoeias, are the prescriptions in them really useful? I can’t see it? Even a classic like "Materia Medica" will inevitably have many omissions." For example, the sentence "there is no cure for the brain-dead" is not correct, la It will definitely be better after going to Professor Yang for a few electric shocks.

"So when you diagnose a patient, you should not be superstitious about the classics. Once you find that a certain prescription is not suitable for the disease, you should immediately stop and analyze the reason. If you can find out the reason, it will be great to prevent future patients from suffering from this poison! A doctor should not only know what it is, but also know why it is so that he can better diagnose and treat patients.”

So this lesson is not about the specific content, but the methodology of scientific research. As long as the methodology is correct, more scientific research results will naturally be born in the future.

"In the next class, we will talk about the two famous experiments of Russian physiologist Ivan Petrovich Pavlov, and I will prepare the experimental equipment then." Then Shen Long announced the dismissal of the get out of class.

This class aroused huge repercussions in the Peking University, and the students in the medical practice hall spread the news to the ears of other students, so when it was Shen Long's turn to attend the class next week, not only the medical practice hall Students and teachers have all arrived, and there are many more students who came after hearing the news. They all want to learn about the latest western scientific and technological knowledge.

After Shen Long came in, the students felt strange, why did they bring a dog with them in class? Shen Long ignored them and talked about Pavlov's life, "Ivan Petrovich Pavlov was born in an ordinary family in Ryazan, a small Russian city. Later, Tsar Alexander II of Russia issued a decree allowing gifted children from impoverished families to go to school for free, so Pavlov got the opportunity to study."

"Later, he learned about Darwin's theory of evolution, and was influenced by the book "Reflex of the Brain" published by the famous Russian physiologist Sechenov in 1863. He gradually became interested in natural science; Admitted to St. Petersburg University,

First entered the law department, then transferred to the Department of Physics and Mathematics, majoring in natural sciences; Sechenov was the professor of physiology here at the time, while the young Mendeleev was the professor of chemistry, and then Pavlov and Mendeleev were still together Founded the Tomsk Imperial University and trained many talents for Russia. "

It is not suitable for Shen Long to talk too much about politics now, but he can use the biography of foreign scientists to let them understand the basic situation of foreign countries, what kind of environment can produce great scientists, and thus trigger his thinking.

These words did not arouse much repercussions among the students of the medical school. Xu Dingchao and others only praised Pavlov for his difficulty in studying, but it was different when it reached the ears of those students who had begun to have revolutionary tendencies.

After explaining Pavlov's information, Shen Long began to do experiments. Pavlov liked to toss the dog very much, and designed a variety of experiments, the most famous of which were the digestive tract experiment and conditioned reflex experiment. The digestive tract experiment It was a bit bloody, and it would be better if only the students of the medical school were there, but it would be a bit inappropriate to have so many people eating melons.

So Shen Long only demonstrated the conditioned reflex experiment to them, "After I went back last time, I bought this dog on the street, and when feeding it every day, I would ring the bell before feeding; after several times in a row, I tried ringing the bell once without feeding, and found that although the dog had nothing to eat, it still drools, and before repeated training, the dog will not respond to the ringing of the bell. This is Pavlov's conditioned reflex test gone."

"Pavlov inferred from this point that after several consecutive experiences, the dog regarded the ringing of the bell as a signal to eat, thus triggering the salivation phenomenon that would occur when eating; this phenomenon is called conditioned reflex, which proves that The behavior of animals is due to the stimulation of the environment, the stimulation signal is transmitted to the nerves and the brain, and the nerves and the brain respond."

Shen Long took out Pavlov's thesis and analyzed it for them. It was still the same as before. He paid the most attention to the process of Pavlov's design of experiments, analysis of experiments, and summary of experiments, rather than pure experimental results.

In this way, Shen Long gained a firm foothold in the medical practice hall of the Beijing Normal University Hall. Every time he took a class, he could attract many students from other departments and even other schools to come and listen. As long as they did not disturb the normal teaching order, Shen Long would not stop them.

After a while, after heated debates and Xu Dingchao's support, Shen Long's "Integrated Traditional Chinese and Western Medicine" course also received support. From then on, he began to teach two subjects by himself. They came to make trouble, but they bowed their heads one after another in the face of the iron-clad facts, and even many famous doctors became frequent visitors. They would rush over to listen to Shen Long every time he was in class.

The news that the old Bai family of Baicao Hall had a famous medical expert quickly spread inside and outside the capital. Bai Wen was both relieved and a little regretful when he heard it. The comfort was that Jing Qi was promising, but the regret was that she had mentioned several times to let her go. Shen Long came to work at the counter, but Shen Long didn't agree.

Now is not the time to take over the Baicao Hall. If I take over, I will continue to be harassed by many relatives at home. I might as well wait and see, and consider taking over when the time is more suitable.

Two or three years passed quickly, and the medical practice hall of Jingshi University Hall moved to the newly built school building in Bajiao Liulijing outside Qianmen. At this time, Bai Jingwu, who had studied abroad, also came back.
