Chapter 918: : Comparison of Chinese and Western Medicine

Ye Chen knew that Xiao Yang told him that way, and kindly reminded him when he was familiar with him. However, Ye Chen didn't take it seriously. Even if he really didn't cure the old woman by then, the old woman's family would find trouble with him, he was not afraid.
Of course, Ye Chen knew that with his own medical skills, when treating patients with heart, he would compare his heart to heart. The family members of the patients would really not trouble him, but would appreciate him instead.
Judging from the fact that he studied medicine with his grandfather and the patients he came into contact with, this is all the case, that is, only after he came to Shanghai from his hometown did he encounter or hear about medical troubles.
Ye Chen followed Xiao Yang to his office. When Xiao Yang sat down and talked to Ye Chen about gastric cancer, Ye Chen didn't expect that the incidence of gastric cancer would be so high in China.
According to relevant data surveys, gastric cancer ranks first among all kinds of malignant tumors in my country, and the incidence of gastric cancer has obvious regional differences. The incidence of gastric cancer in the northwest and east coastal areas of my country is significantly higher than that in the south.
The incidence rate is high for people over 50 years old, and the incidence rate of men and women is 2:1. The prognosis of gastric cancer is related to the pathological stage, location, tissue type, biological behavior and treatment measures of gastric cancer.
From the analysis of western medicine, the causes of gastric cancer can be roughly divided into several categories. First, the geographical environment and dietary factors.
The incidence of gastric cancer has obvious regional differences. The incidence of gastric cancer in the northwest and east coastal areas of my country is significantly higher than that in the south.
The high incidence of gastric cancer in people who consume smoked roasted and salted foods for a long time is related to the high content of carcinogens such as nitrites, mycotoxins, polycyclic aromatic hydrocarbon compounds, or pre-carcinogens in the food; the incidence of gastric cancer in smokers The risk is 50% higher than that of non-smokers.
Second, it is related to Helicobacter pylori infection. The hp infection rate of adults in the high-incidence area of ​​gastric cancer in my country is over 60%.
Helicobacter pylori can promote the conversion of nitrate into nitrite and nitrosamines and cause cancer; HP infection causes chronic inflammation of the gastric mucosa, and environmental pathogenic factors accelerate the excessive proliferation of mucosal epithelial cells, leading to aberrations and carcinogenesis; Helicobacter pylori toxicity The products caga and vaca may have cancer-promoting effects. The detection rate of anti-caga antibodies in gastric cancer patients is significantly higher than that in the general population.
Third, precancerous lesions. Fourth, inheritance is related to genes.
Gastric diseases include gastric polyps, chronic atrophic gastritis, and remnant stomach after partial gastrectomy. These lesions may be accompanied by varying degrees of chronic inflammatory processes, intestinal metaplasia or atypical hyperplasia of the gastric mucosa, and may turn into cancer.
Precancerous lesions refer to the histopathological changes of the gastric mucosa that are prone to cancer, and are the borderline pathological changes during the transition from benign epithelial tissue to cancer.
The dysplasia of gastric mucosal epithelium is a precancerous lesion. According to the degree of cell atypia, it can be divided into mild, moderate and severe third degree. Severe dysplasia and well differentiated early gastric cancer are sometimes difficult to distinguish.
Genetic and molecular biology studies have shown that the incidence of gastric cancer in blood-related relatives of gastric cancer patients is four times higher than that of the control group.
The carcinogenesis of gastric cancer is a multi-factor, multi-step, and multi-stage development process, involving changes in oncogenes, tumor suppressor genes, apoptosis-related genes, and metastasis-related genes. The forms of genetic changes are also diverse.
The clinical symptoms of gastric cancer, most patients with early gastric cancer have no obvious symptoms, and a few people have nausea, vomiting or upper gastrointestinal symptoms similar to ulcer disease.
Pain and weight loss are the most common clinical symptoms of advanced gastric cancer. Patients often have clear upper gastrointestinal symptoms, such as upper abdominal discomfort, fullness after eating, upper abdominal pain aggravated as the disease progresses, appetite decreased, and fatigue.
Depending on the location of the tumor, there are also special manifestations. Gastric cardia cancer may have retrosternal pain and progressive dysphagia; gastric cancer near the pylorus may have pyloric obstruction; after the tumor destroys blood vessels, hematemesis, melena and other gastrointestinal bleeding symptoms may occur.
Persistent pain in the abdomen often indicates that the tumor extends beyond the stomach wall, such as supraclavicular lymphadenopathy, ascites, jaundice, abdominal mass, anterior rectal palpation, and masses. Patients with advanced gastric cancer often suffer from anemia, weight loss, malnutrition and even cachexia.
Western medicine examines whether a patient has stomach cancer, mainly through x-ray barium meal examination, fiber gastroscopy, abdominal ultrasound, spiral CT and positron emission imaging.
These are all checked by modern medical equipment and can be clearly checked under normal circumstances. In traditional Chinese medicine, powerful Chinese doctors can confirm the symptoms based on the patient's symptoms, such as sudden discomfort and weight loss in the stomach, and then dialectically by seeing, hearing, asking, and so on.
However, most Chinese doctors now pass modern medical equipment examinations. On the one hand, it can generate income, and the cost of a check-up is not low. On the other hand, those doctors who are not skilled in traditional Chinese medicine cannot confirm whether a patient has cancer through dialectics alone.
Therefore, through the inspection of modern medical equipment, there is no doubt that it can be quickly confirmed and can make more money for the hospital. Why not do it?
As for Western medicine in the treatment of gastric cancer, one is surgical treatment, including radical surgery. The principle is to remove part or all of the stomach including the cancerous focus and possible infiltration of the gastric wall, and remove the lymph nodes around the stomach as a whole according to clinical staging standards , Rebuild the digestive tract.
One is palliative surgery. The primary tumor cannot be removed. It is an operation to relieve the symptoms caused by obstruction, perforation, bleeding and other complications, such as gastrojejunostomy, jejunostomy, and perforation repair.
This is the basic surgical treatment of western medicine for gastric cancer. Additional treatments include chemotherapy, radiotherapy, hyperthermia, immunotherapy and so on.
Xiao Yang sat there and told Ye Chen in detail. If the patient is lucky and found early and cured by surgery, the patient needs to cut part of the stomach and cut off the part where cancer cells appear to prevent cancer cells from appearing. Spread, these patients survived.
However, the most important thing is to prevent the spread of cancer cells after surgery. Therefore, there are elements of luck inside and outside, and there is also a certain period of time inside. It may be two years, maybe four years, or even longer. If the cancer cells do not reappear or spread, it is enough to explain that through surgical cutting After the cure, the patient's condition is considered stable.
However, the reason why cancer is said to be terminally ill, which makes people listen to cancer. Naturally, this cancer is not so easy to treat, and even the cure rate is very low. It can be said that the mortality rate is very high before it can be called terminally ill.
This is also the case for many gastric cancer patients. After the operation is successful, it is not long before the cancer cells recur and spread. The patients can only undergo chemotherapy, radiotherapy, and other multi-stage treatments. When lucky, they can suppress the cancer cells. It continued to spread. Unfortunately, like the old man, the cancer cells spread wildly and entered the advanced stage of gastric cancer. By then, it was already beyond treatment.
As for Chinese medicine, Ye Chen said that the term gastric cancer is also a foreign term in western medicine. In Chinese medicine, there was no such thing before. However, the occurrence of gastric cancer is classified as epigastric pain and choking in Chinese medicine according to different symptoms. Hiccups, beams, clusters and other categories.
For those who have never studied Chinese medicine, it is naturally difficult to understand why gastric cancer falls into the category of so many diseases in Chinese medicine.
This is like in traditional Chinese medicine, leukemia is classified as a condition of fatigue.
