For students who love chemistry, doing experiments is addictive, and after an hour, everyone is still interested, even though everyone is hungry.

Qu Guangquan looked at the time, it was almost a quarter past six, and if it didn't end, dinner would be a problem, so he clapped his hands: "That's all for today's experiment." ”

"Hey, it's not fun!"

"Just do it a little longer. ”

"Please, Mr. Qu!"

"It's too late, the cafeteria is about to close!" Qu Guangquan shrugged, "While everyone is still gone, I want to say something." Everyone heard it just now, Mr. Zhao's mother has undergone surgery, Mr. Liu is in her thirties, her mother will not be young, at least fifty or sixty years old, surgery at this age is basically a serious illness!"

"Yes, Qu Guangquan or let's go to the hospital tomorrow to have a look, Teacher Liu has paid too much for us!"

"Well, everyone will go to the hospital tomorrow, raise your hand in agreement!"

All of them raised their hands.

Chen Yao walked to the front in three steps and two steps, "Everyone supports Qu Guangquan's suggestion, but you may not know the situation in the hospital, if we all go, it may not be appropriate, it is best to choose two representatives to visit Teacher Zhao's mother on behalf of everyone." ”

"Yes! We're a little too many!"

"Let Qu Guangquan be a representative, everyone agrees or disagrees!"

"Let Chen Yao go too, our Ossaiban Chen Yao is the most capable of doing things!"

"Chen Yao's mother is from the hospital, and it is easy to find which department Mr. Liu's mother is in for surgery, otherwise, where can I find the hospital when it is so big?"

"Hey, I can't go to see a patient tomorrow, tomorrow is the first day of the new year, and the fifteenth day of the first day of the new year in Qiaozhou is a day to incense the gods, so it's not suitable to see a patient!"

After a lot of gossip, everyone bought a gift for ten yuan, and asked Qu Guangquan and Chen Yao to visit the hospital on behalf of everyone the day after tomorrow.

As soon as school ended on Thursday morning, Chen Yao and Qu Guangquan found Teacher Liu Yanqiu's mother in the thoracic surgery ward according to Chen Yao's mother's instructions.

As soon as Liu Yanqiu saw his two proud disciples in the corridor holding flowers and carrying eggs and milk, tears flowed out of their eyes. "Why are you here? study so nervous!"

"No matter how intense we are, we also want to express our sincere respect for you and your family. Your dearest relatives are sick and still work overtime to lead us to do experiments, such a good teacher, we must express our gratitude. Chen Yao spoke very decently.

"With a good student like you, no matter how hard and tired I am, I'm worth it!" Liu Yanqiu held one in one hand, and her heart was very excited.

"Is it the family of the 31-bed patient?" said an elderly doctor in good spirits.

"Hello Professor Wang, thank you for coming from Yanjing to operate on my mother. ”

At that time, for example, some major surgeries in Qiaozhou Hospital could not be performed by their own doctors, so they invited experts from big cities to make regular rounds to perform surgeries.

Qu Guangquan's mother was also operated on by a specialist from the provincial hospital at that time.

There are pros and cons to doing so.

The advantage is that it is greatly convenient for patients: first, there is no need to run so far, and those who are tired of traveling are not necessarily hung up with the expert number, and it is difficult to wait for a bed in a big city, and second, the cost is greatly saved, the per capita income at that time was too low, and medical insurance was only available to public officials, and the small people sometimes really couldn't afford it.

The disadvantage is that the specialist stays in Qiaozhou for a short time, and often within a few days of surgery, the specialist leaves, and the follow-up treatment cannot keep up. Moreover, before the operation, the expert only looked at the film and the examination report, and the real contact with the patient was not long, coupled with the poor equipment at that time, sometimes after the operation, it was found that the diagnosis was biased.

"I'm short on time, so I'm going to ask you to come to the office to talk, and we'll talk about your mother in the hallway. The doctor said.

"Yes, good. ”

"The pathological biopsy has just come out, and it is basically the same as the previous judgment that it is lung cancer, and your mother's surgery is basically successful, and basically all the visible lesions have been removed. Professor Wang paused, "Your mother's lung cancer was detected relatively early, and the surgery was done in a timely manner, and according to the current medical conditions, the survival rate can be as high as 40%. ”

"It's so timely, why is it only 40%!" Chen Yao whispered to Qu Guangquan.

"Because lung cancer is complex. Qu Guangquan motioned to continue listening.

"I want to tell you about your mother's chemotherapy next, and according to the new research now, your mother should be the first choice for etoposide. ”

"Small cell lung cancer?" Qu Guangquan interjected instinctively.

"It's small cell lung cancer. Professor Wang actually heard Chen Yao's words just now, but the development of medicine can only reach this point, Professor Wang also tried his best, and he didn't want to ignore it, but when he mentioned etoposide, Qu Guangquan could actually judge that it was small cell lung cancer, and he was very curious: "You are-"

"These are my two students. Liu Yanqiu thought that Chen Yao and Qu Guangquan's interjection had upset Professor Wang.

"Well, can you tell me why when I say etoposide, you can tell that the patient is small cell lung cancer?"

There are different types of lung cancer, and Professor Wang only said that it was lung cancer, but at that time, lung cancer was divided into small cell lung cancer and non-small cell lung cancer. Later generations have divided lung cancer into four types: squamous cell carcinoma, undifferentiated carcinoma, adenocarcinoma, and alveolar cell carcinoma, which is more conducive to precise treatment and convenient selection of targeted drugs.

In this era, targeted drugs are basically in the laboratory, and they are all in Europe and the United States, and Chinese mainland is known by several experts at the cutting edge.

"Well, because etoposide is mainly for small cell lung cancer, the effective rate is 40%, increasing to 85%, and the complete response rate is 14%~34%. For small cell lung cancer, oral administration is more effective than intravenous injection. Qu Guangquan said casually.

"Is this really your student, a high school student?" Professor Wang's eyes widened.

"It's really my student, his name is Qu Guangquan, and this kid is extremely talented in biochemistry. Qu Guangquan's unthinking words also stunned Liu Yanqiu.

"How can a high school student be?"

"Professor Wang, my mother is also a cancer patient, but she has breast cancer. Qu Guangquan also felt that he was a little too special, so he moved his mother's illness out as a shield.

"Understandable, understandable. Professor Wang has seen countless family members of cancer patients, and almost all of them can go to heaven and earth in order to cure patients, "Since your students know, I will briefly say it." The side effects of etoposide are too great, and your mother's constitution is very poor, mental anxiety, and some stomach ulcers, even with maltoselenium, it may still have a greater response than the average person's chemotherapy. ”

Etoposide is widely used in cancer chemotherapy regimens, but due to the severe bone marrow suppression, gastrointestinal reactions, liver and kidney damage in the chemotherapy process, it is necessary to take maltoselenium at the same time.

Maltoselenium is an antioxidant and anti-cancer substance. When taken at the same time as chemotherapy drugs, it can effectively enhance the activity of lymphokine IL-12 and improve immunity, and some cancer cells are less sensitive to etoposide, so maltoselenium can help control and kill such cancer cells, on the other hand, it has also been proven to improve the activity of white blood cells.

"Professor Wang, can she match thalidomide in this situation?" Qu Guangquan considered his tone, trying not to show that he was speaking too abruptly.

But if it's not abrupt, it's not okay, Professor Wang immediately overreacted -

"What, reaction stop - you want to use it too!"
