Great Power

A thick stack of X-rays was placed on the table, and Zheng Jianguo, who came in front of him with a polite sentence, knew that he had found the treasure. The barium meal is not very accurate for checking gastrointestinal diseases, but it is for ordinary people on physical examination. .

Considering that my place is a cancer hospital, most of the patients admitted can only be in the late stage with obvious symptoms. In this case, use a barium meal to confirm that the abnormality shown in the niche part above will be very obvious. Of course, in this case, there is no way to confirm the presence or absence of Helicobacter pylori.

And this is where Zheng Jianguo’s suspicion was set up. His purpose this time was to have obviously fewer but more gastroscopy pictures next to him, so he pretended not to understand and was shy and watched a few barium meal X-rays. Later, the probing hand picked up the photo of the gastroscope next to him, and opened his mouth curiously: "How come there are so few gastroscopes?"

"Well, the patients in our hospital are generally older. Although gastroscopy can confirm the degree of tumor development to a certain extent, it can stimulate the patient's body. Some elderly patients can't stand it and are unwilling to do it—"

Qin Lianzheng turned his head and glanced, then spoke, and then turned his head to do his work. Zheng Jianguo naturally did not forget the appearance of the second-generation gastroscope. On the contrary, he was quite familiar with that thing. In his memory, Zheng Donghua's stomach problems had been used many times. , It will cause certain harm to the patient's physical and mental state, especially to the elderly.

Asking it as a question at the moment is just the cautiousness in Zheng Jianguo's heart. After all, as a graduate student who studied for a year, he came to watch the film directly. This is beyond people's common understanding, although he bears the name of a graduate student. It's just that the accumulation of some experience is inseparable from these processes. I immediately took out a picture of the gastroscope and was stunned at a glance.

In the photo, the outline of the mucous membrane in the middle of the stomach is obviously abnormal. However, this is not the reason why Zheng Jianguo was stunned. His gaze fell on the side of the obviously cancerous tissue, and the erosion area and the bulge that can be distinguished at a glance. The performance resembled the result of the propagation of Helicobacter in his memory-ulcers.

Found the first one?

Zheng Jianguo turned the photo over and took a look, glanced at the date above and swallowed: "It was in January 1977—"

With advanced gastric cancer in January 1977, don’t think about other things. Zheng Jianguo turned his head and looked at the busy doctor next to him. His excitement calmed down, and he took the remaining gastroscope pictures to look at himself. When I got up, I didn't look at a few pictures and a voice came from behind: "Can you understand this?"

"The X-ray film is incomprehensible, and the white and black are blurred. This gastroscope photo can still be understood."

Zheng Jianguo didn't expect Qin Lianzheng to be behind, holding the photo in his hand with his finger, turning his head and saying: "This is cancerous tissue, right?"

"Well, tumor."

Qin Lian nodded and said with a smile on the front. He didn't expect Zheng Jianguo to tap the ulcer and the surrounding area of ​​the bulge next to his finger, so he listened to him and said, "What's going on here?"

"Well, it should be caused by drinking too much spicy, and the rate of gastric acid secretion has an upper limit. If you drink too much spicy at one time, usually overeating will easily cause such ulcers."

Looking at Zheng Jianguo’s serious questioning, Qin Lianzheng suddenly had the urge to be a good teacher. He stretched out his short and thick index finger and clicked on the photo. A pair of eyes swept over the fluffy face in front of him, and finally changed his words: "You seem Not big?"

"Yes, well, thank you for teaching me so much, then I'll go back."

Looking at it aroused the curiosity of the other party, Zheng Jianguo, who had achieved his goal, put down the photos and organized them. He saw 23 photos this time. Among them, 22 of them were surrounded by tumor tissues of different sizes. Ulcers, and according to his memory, these ulcers should be caused by Helicobacter, and it is of little significance to continue.

Qin Lianzheng’s remarks are exactly what the gastroenterologists have at this time when facing patients with gastric diseases. Spicy and alcoholic beverages, such as cold and hot foods, are all causes of gastric ulcer and gastritis. Of course this This statement is true to a certain extent, but it ignores the role of Helicobacter in the middle.

After leaving with Qin Lianzheng, Zheng Jianguo got in the car and went back to school. He is now in a better mood. There is no Helicobacter in his memory, but people put it into a normal category in advance based on "experience." For researchers To say, it is surrendered to authority and dare not have the slightest objection.

For the first time, Zheng Jianguo felt the pressure brought by authority firsthand. Of course, it also made him full of fighting spirit to find this thing. He returned to school and went straight to the office at the east end of the second floor of the teaching building. He did not expect that the half-covered door was pushed by someone. Opening, Wei Jianran looked at him with dissatisfaction: "I have someone tell you something to find you. Didn't you receive a message?"

"I got it, I have something wrong."

Recalling what someone had said yesterday, Zheng Jianguo glanced at Ye Minde who was writing at the desk in the room, and when he knew it was not about his own business, he said, "You have something to do with me?"

"There must be something."

Wei Jianran frowned and glanced at the goods, and said, "The reporter from China Youth Magazine wants to interview you. They have waited here for half a morning and left--"

"Well, it's good to go."

Zheng Jianguo nodded. The magazine was reopened last month, thinking that he wanted to rub his hot traffic, he immediately said with a wry smile: "You don't know that I am introverted——"

"You are an introvert, you are just lazy."

Wei Jianran's round face was a bit dark, and she naturally knew that this guy was very stubborn in some way after getting along for so long. She waved her hand quickly and turned away: "Anyway, it's your business, if you don't care about it, then forget it. "

"Well, I will trouble you, Teacher Wei walk slowly."

Zheng Jianguo yelled and watched Wei Jianran disappear into the corridor, turned around and walked into the office to Ye Minde, who was already sitting upright. His eyes fell on his cracked enamel tea jar, and he reached for the kettle and added water. Ye Minde glanced at him and said, "Why, I think you are in a good mood?"

"Hehe, then I must be in a good mood, and my body is so good that I can eat well~"

Putting the tea mug with water on the old man's hand, Zheng Jianguo, who started to run the train with his mouth, turned his head and glanced at the door, then turned his head to look at Ye Minde, who looked like an old farmer with a dark face, and said, "Doctor Qin Lianzheng is more enthusiastic , Tell me that the ulcers and bulges on the side of the gastroscopic cancer tissue photo are caused by the bad habits of drinking and eating spicy food. I have an immature question and would like to ask you for advice."

"Immature—problem?"

Ye Minde picked up the tea mug and tested the temperature, then felt a little cold and put it down and said: "The hot water is a little bit less--"

"Well, I deliberately gave you less hot water."

As Zheng Jianguo said, he looked at the door again, his eyes fell on the face of the suspicious old man, and continued: "Esophageal cancer, you know, the saying I heard earlier when I looked at the photo of the stomach tumor should be what the doctors thought. Tumors and cancerous changes in the stomach are caused by bad eating habits such as eating chili and drinking alcohol, right?"

"Correct!"

Ye Minde didn’t know what medicine was sold in this gourd, but the stomach tumor was caused by bad eating habits. It was the unified default of research and medical staff at this time, and he felt a vague idea in his mind flashed away. There was also some impatience on the lips: "What do you want to say?"

"Stomach cancer is caused by bad habits such as drinking and spicy, but what about esophageal cancer?"

Zheng Jianguo looked at the old man’s cheeks and said, he saw Ye Minde’s complexion suddenly changed and his eyes widened. However, Zheng Jianguo had not finished what he wanted to say. The focus of his expression was not to elicit esophageal cancer from the side. He was also stimulated by cold and heat and bad. Living habits, such as hard object scratches leading to fungal infections, are the two big sayings about cancer at this moment: "I squatted in the library for more than a month last month and learned that cancer is caused by viral infections and tissue mutations. Two versions—"

"Ok?"

Ye Minde, who is full of esophageal cancer and bad diet, heard this, and his attention suddenly shifted. As a researcher in the field of microbiology, he quickly understood what this guy wanted to express, and he was surprised. Nodded and quickly said, "What you said is a bit interesting—"

"I watched and listened to the tumor hospital for a while. The doctors' remarks are focused on the appearance of tumors due to bad habits in life. It is not caused by viral and bacterial infections, and only after the appearance of tumors. It will cause the cancer to spread, instead of tumors in other digestive parts at the same time. Does this mean that the patient’s own tissue cells have problems that cause the tumor cells to divide indefinitely?"

Normal human cell division is limited in the number of times. It usually stops after dozens of times. If it is not enough, it is enough to regenerate a cell to make this division. This is also required by the normal human body and occurs under normal circumstances. It is just cancer. On the other hand, cells have broken through dozens of times of limitations. In terms of human beings, they have broken through the limit of age and reached the realm of immortality—infinitely dividing themselves.

Imagine if people can live forever, what will the world look like?

Putting aside the external factors of food, clothing, housing and transportation, an adult woman can give birth to one child a year on average. Even if a couple only needs two children, it will double according to the generation of 20 years, and it will be 1:2 after 10 generations. :4:8:16:32:64:128:256:512.

And if the unit is 100 million people?

Simply put, there are 51.2 billion people in two hundred years of ten generations!

Neither humans nor the earth can bear this situation. Of course, Ye Minde’s attention has been distorted by Zheng Jianguo at this moment. He saw his eyes shining brightly and said: "Push it down according to your statement. Prove that gastric cancer cells come from human cell mutations? Or is it the mutation caused by virus infection of external factors, bacterial infection, food and dietary stimulation?"
