Chapter 2248: Bai Jingwu is back

As early as 1862, when the Peking University Tongwenguan opened, a blackboard appeared. Nowadays, this teaching tool is also used in the medical practice hall of Peking University. Shen Long took chalk on the blackboard and wrote his "About a Donkey Skin" The general content of the extract on the treatment of several common diseases of women" is written on the blackboard.
He has been working as a teacher at Tsinghua University next door for decades, and his teaching experience is very rich. The course is very interesting and the students are enchanted.
Shen Long pointed to the diagrams and logic chains on the blackboard and said to the students, "In fact, this paper is about the use of gelatin for women. This is not a rare thing in traditional Chinese medicine. Presumably you are in various It’s much more in the Pharmacopoeia; so the main content of this class today is not in the paper itself."
"It lies in the scientific research methods embodied in this thesis, whether a medicine is effective, why it is effective, what method is used to judge, and what method to verify, this is the key; medical books accumulated in China for thousands of years There are countless pharmacopoeia. Are the prescriptions really useful? I can’t see it? Even if classics such as "Materia Medica" are inevitably negligent." For example, the sentence "There is no medicine for the brain disabled" is wrong, pull A few visits to Professor Yang will definitely be better.
"So you should not be superstitious when you diagnose patients. Once you find that a certain prescription is not symptomatic, you should stop and analyze the reason immediately. If you can find out the reason and let the subsequent patients no longer suffer from this poison, it will be great! Healers should not only know what it is, but also why it is so that they can better diagnose and treat patients."
So this lesson is not about specific content, but the methodology of scientific research. As long as the methodology is correct, more scientific research results will be born in the future.
"In the next lesson we will talk about two famous experiments by Russian physiologist Ivan Petrovich-Pavlov. I will prepare the experimental equipment by then." Then Shen Long announced the get out of class.
This class caused a huge response inside the Jingshi University hall. The students in the medical practice hall spread the news to the ears of other students, so when it was the turn of the next week when Shen Long took the class, not only the medical practice hall The students and teachers have arrived, and there are many more students who have heard of the news. They all want to know the latest knowledge of Western technology.
After Shen Long came in, the students felt strange. Why should they bring a dog in class? Shen Long ignored them and talked about Pavlov’s life.
Ivan Petrovich Pavlov was born in an ordinary family in the Russian city of Ryazan. He has worked hard since childhood and has a wide range of hobbies. Post-Russian Tsar Alexander II issued a decree to allow poor but gifted children from families to go to school for free, and Pavlov was given the opportunity to study."
"He later learned about Darwin's theory of evolution, and was influenced by the well-known Russian physiologist Sechenov's "Reflex of the Brain" published in 1863. He gradually became interested in the natural sciences; at the age of 21 he was with his brother in 1870 Admitted to the University of Saint Petersburg, first entered the Faculty of Law, and then transferred to the Department of Physics and Mathematics, majoring in natural sciences; Sechenov was the professor of physiology here, and the young Mendeleev was a professor of chemistry, and then Pavlov and Men Terev also co-founded the Tomsk Imperial University and trained many talents for Russia."
Shen Long is not suitable for telling too much about politics, but he can use the life of foreign scientists to let them understand the basic situation of foreign countries. What kind of environment can give birth to a big scientist, which caused him to think.
These remarks did not cause much repercussions among the students in the medical museum. Xu Dingchao and others just praised that Pavlov was not easy to study, but it was different in the ears of students who have begun to have a revolutionary tendency.
After telling Pavlov's information, Shen Long began to do experiments. Pavlov liked to toss dogs and designed a variety of experiments, the most famous of which are the digestive tract experiment and conditioned reflex experiment. The digestive tract experiment Some are bloody, and only the students in the medical hall are better. It is not suitable for the people who eat so many melons.
So Shen Long only showed them the conditioned reflex experiment. "After I went back last time, I bought this dog on the street. When I fed it every day, I would shake the bell first before feeding. After several consecutive times, I tried a rattle but did not feed, and I found that although the dog had nothing to eat, it still drooled. Before repeating the training, the dog will not respond to the ringing. This is Pavlov's conditioned reflex test. Now."
"Pavlov infers from this point that after several consecutive experiences, the dog regards the bell as a signal for eating, thus triggering the phenomenon of drooling caused by eating; this phenomenon is called conditioned reflex, which proves The behavior of animals is stimulated by the environment, and the signals of the stimulation are transmitted to the nerves and the brain, and the nerves and the brain react in response."
Shen Long took out Pavlov's paper and analyzed it for them. It was the same as before. The most important thing was the process of Pavlov designing experiments, analyzing experiments, and summarizing the experiments, not just the experimental results~www .EbookFREE.me~ In this way, Shen Long has a firm foothold in the Medical Practice Hall of Beijing Normal University. Every class can attract many students from foreign departments or even foreign schools to come and listen. As long as they do not disturb the normal teaching order, Shen Long will Won't stop.
After a period of time, after fierce debate and Xu Dingchao’s support, Shen Long’s "Integrated Chinese and Western Medicine" course also received support. Since then, he has taught two subjects by himself. After the news spread, many famous Chinese doctors in Beijing Came for trouble, but in the face of the iron truth, they all lowered their heads, and even many famous doctors became regular visitors, and they would rush over to listen every time Shen Long took classes.
The news from Baicao Bai's old house that everyone had a medicine soon spread throughout the capital and beyond. Bai Wenshi was both comforted and a bit sorry to hear that. Jing Qi was gratified, but unfortunately she mentioned it several times. When Shen Long came to the cabinet, Shen Long did not agree.
Now is not the time to take over the Baicao Hall. If I take over, I still have to continue to be harassed by many relatives in the family. It is better to wait and wait and wait until the time is more appropriate to consider taking over.
Soon after two or three years passed, the Medical Practice Hall of Beijing Normal University moved to the new building of the octagonal Liulijing outside the front door, and at this time, Bai Jingwu returned to study abroad.
