Chapter 188 Race identification? !
This is the second time Zhang Yang has heard arguments about "lung adenocarcinoma" that may be caused by the pneumonia virus.
The last time he heard about this was from Director Dai of Xinqiao Hospital.
Director Dai's problem is that the "pneumonia virus" first induces a high incidence of pulmonary nodules, and then the pulmonary nodules have a certain chance of deteriorating into malignant nodules and eventually becoming lung adenocarcinoma.
However.
This conjecture was later rejected after querying "lung adenocarcinoma" data in other parts of the world.
After all, pneumonia viruses are present in all parts of the world, but lung adenocarcinoma data in other foreign regions have not improved significantly. As a result, the conclusion that lung adenocarcinoma is caused by pneumonia viruses is untenable.
Zhang Yang and Director Dai also thought about whether it might be a racial issue, but this involved deeper virus analysis, which was neither Director Dai's major nor Zhang Yang's, so the matter gradually stopped. Come down.
But Zhang Yang didn't expect that just two months later, he would hear from Wei Tian another conclusion that was verified in different ways but was almost the same.
And this time the data collected by Wei Tian is obviously more specific and convincing. This is all first-hand real data from real patients in the clinical trial of Qingshan Pharmaceutical's "Nano Nodule Developer"!
"One data source may be wrong, but two or three data sources all point to the same conclusion!"
"Could it be that the recent increase in the incidence of 'lung adenocarcinoma' is really related to the 'pneumonia virus' 'Relevant? "
Thinking of this, Zhang Yang frowned, and for the first time he really paid attention to the pneumonia virus.
What is pneumonia virus?
To put it simply, it is an epidemic virus that, like hepatitis B virus and hepatitis A virus, specifically targets the invasion of lung tissue and causes lung inflammation.
The virus first causes upper respiratory tract infection, and then spreads downward to the lung tissue, causing inflammation and other pathological damage in the lungs.
In fact, humans first discovered the pneumonia virus as early as 1947. With years of evolution and mutation, the pneumonia virus has long coexisted with humans and is permeated in the air almost all the time.
Only in autumn and winter every year, due to the drop in temperature, the mucous membranes of the human nasal cavity and respiratory tract shrink when exposed to cold, which reduces the secretion of mucus that blocks germs, making pneumonia viruses more likely to occur in winter.
Young adult men may have never noticed it, but anyone with elderly or children at home will know that every winter, the elderly and children are particularly susceptible to colds, fevers and coughs. If they cough for a long time, they will develop into pneumonia if they are not careful.
Once pneumonia develops, you must be hospitalized for infusion and anti-inflammation to control the inflammation as soon as possible to avoid more serious consequences such as white lung and death.
According to statistics, more than 50,000 people die from influenza combined with pneumonia in the United States every year.
Of course.
Although the elderly and children are high-risk groups, this does not mean that young people do not need to worry at all.
The pneumonia virus first enters the throat from the respiratory tract, that is, the nose and mouth. If the host has strong immunity at this time and takes some medicine after noticing the cold, or gets better after a sleep, then the pneumonia virus will be transferred to the throat. It strangles the upper respiratory tract and prevents it from developing into the lungs.
But there are always some young people with weaker constitutions.
The main symptoms of the pneumonia virus are colds and coughs, and in a few people, fever and muscle aches.
After these people catch a cold and cough, it often takes a week and a half to recover even if they take medicine. Zhang Yang remembers that there was a young girl in the office who would cough for more than half a month every time she caught a cold.
This means that the pneumonia virus has invaded the lung tissue and caused certain damage.
The patients mentioned in Wei Tian's words who were infected with the pneumonia virus and are now diagnosed with malignant nodules are exactly this group of people.
Zhang Yang suddenly felt creepy.
You know, when winter comes, there are not only one or two patients who have colds, fevers, and coughs, and who can guarantee that they can 100% resist the pneumonia virus?
If you are infected with the pneumonia virus, it may cause pulmonary nodules, which may lead to lung adenocarcinoma. Even if the chance is very small, this can be called——
Terror!
It is no exaggeration to say that by then, almost all Chinese people will be under the shadow of lung adenocarcinoma, and the "pneumonia virus" will also become the real top carcinogen!
Zhang Yang took a deep breath in disbelief. At this moment, Wei Tian on the side continued:
"Boss, I read a news report today that the pneumonia virus that is prevalent in our country this winter is more transmissible than last year. It is still the end of November, and winter has not yet begun. The respiratory medicine departments of major hospitals are already full, and there are even beds. A tense situation.”
“Even several colleagues in the drug research and development center have been suffering from colds and coughs recently, and they are probably infected with this year’s pneumonia virus!”
Zhang Yang’s face suddenly became solemn, An unprecedented sense of oppression surged into my heart.
After a while, he whispered:
“Let’s go to the hospital with me.”
"Go to the hospital?"
"Well, I'm going to the hospital to see for myself."
......
Checking lung nodules and treating pneumonia are two different departments.
Pulmonary nodules are usually detected during physical examinations at work units. Under normal circumstances, even if they are 1CM long, they will not cause pain or cause any adverse reactions.
If you really feel chest tightness or vomiting blood, you are already in the middle and late stages of lung cancer, and it has nothing to do with pulmonary nodules.
So.
Pulmonary nodules are generally treated by thoracic surgery, and their treatment is mostly surgical resection.
Pneumonia is a viral invasion, and the department it is located in is usually the Department of Respiratory Medicine.
Zhang Yang and Wei Tian quickly arrived at the respiratory medicine inpatient department of Chengdu Third Hospital. Wei Tian was very considerate and put a mask on Zhang Yang.
But as soon as he walked into the corridor of the department, Zhang Yang's frown deepened.
The narrow corridor of the inpatient department was lined with temporary beds on both sides. As far as the eye could see, there were no empty seats.
The number 120 is written next to the nearest clinical bed, which also means that at least 120 patients are admitted to the inpatient department.
120 people, this is already the department operating at full capacity.
Are there already so many pneumonia patients before winter begins?
Zhang Yang's frown fell into the eyes of Wei Tian, who also sighed slightly and said:
"Boss, this is just the Department of Respiratory Medicine. The Department of Pediatrics is really overcrowded. There are many children who don't even have beds. I can only sit and inject, atomize, and go back after the infusion."
Zhang Yang was silent and didn't speak, and then walked quickly to the other end of the corridor.
As he walked, he observed the patients on the temporary beds, including those in their 40s, 50s, and 60s and 70s.
Some people wore oxygen hoses and were ready to breathe oxygen at any time, while others looked at Zhang Yang curiously as they passed by, coughing occasionally.
After a while, Zhang Yang walked through the entire corridor of the inpatient department, his expression even more solemn.
I usually don’t feel that I am in good health, but when I came to the hospital, I discovered that there are countless middle-aged and elderly people infected with pneumonia every year!
With emotion, when he and Wei Tian walked slowly to the nurse's station, Director Ding from the Department of Respiratory Medicine trotted over.
Zhang Yang is definitely a well-known figure in the Third People's Hospital of Chengdu. When the nurses at the nurse station said that Mr. Zhang had come to the inpatient department, Director Ding hurriedly ran out of the office.
He also had a chance encounter with Zhang Yang. When he saw Zhang Yang, he hurriedly stepped forward and said excitedly:
"Mr. Zhang, you are here. Why didn't you inform me in advance?"
Zhang Yang also had some impressions of Director Ding. The last copy of "Kidney Toxin Clearing Dialysis Injection" had a plot that said "What disease do you want to have?" Drinking ice." He once asked Dean Zhou for help, and Director Ding was one of the directors who helped. However, at this moment, Zhang Yang had no intention of being polite. After a simple reply, he looked at Director Ding and said:
"Director Ding, these patients are all hospitalized because of pneumonia. "
"And I see that the number of temporary hospital beds has been increased to 120. Is the pneumonia virus so popular this year?"
Director Ding glanced at Zhang Yang confused, but he quickly nodded:
"Mr. Zhang, yes, 75% of the patients in the inpatient department are admitted to the hospital because of pneumonia infection."
“As for this year’s pneumonia virus... it should be more prevalent than last year’s Some; I don’t know about the others, but the overall number of hospitalizations in our hospital this year has increased by about 15% in the same period.”
“I remember that last year, we only had about 100 extra beds.”
Zhang Yang nodded thoughtfully, and then asked the question he wanted to ask the most.
"Director Ding, are there many young people infected with the pneumonia virus this year?"
Director Ding was startled for a moment, then came to his senses.
"Mr. Zhang, what you should want to ask is: 'Are many young people coming to the clinic this year with colds and fevers?', right?"
"Well, yes, that's it Meaning."
"Oh, I know, I do feel that there are a lot more young people seeing colds and coughs in the outpatient clinic this year!"
"And judging from the current situation, the pneumonia virus that is circulating this year has particularly many cough symptoms, and most of them have lasted for a week or even more than half a month, which is a bit troublesome."
As he said that, he suddenly raised his head and looked at Zhang Yang, a trace of excitement and expectation flashed in his eyes.
"Mr. Zhang, you are not going to develop a special treatment for pneumonia or pneumonia virus, are you?"
"Ouch! If you really want to develop such a pneumonia drug, Just ask if you need me, and I will definitely cooperate with you."
Hearing this, Zhang Yang couldn't help but smile.
He does know that now not only netizens, but also professional doctors are looking forward to them entering the field of their own diseases and quickly developing drugs with outstanding effects.
Soon, he shook his head and denied:
“No.”
After saying this, he saw a look of loss on Director Ding’s face. I sighed secretly in my heart and sighed to myself:
"Pneumonia is nothing!"
"This matter is probably a hundred times more important than developing a pneumonia drug!"
Zhang Yang sighed in his heart, and Wei Tian on the side also noticed Director Ding's disappointed expression.
He knew that Zhang Yang didn't want to explain anything now, so he hurriedly stood up and said: "Director Ding, don't worry, although we don't have a pneumonia drug research and development plan now, we will seriously consider it. .”
“No, Mr. Zhang has come to learn about the pneumonia situation in person.”
Director Ding's expression suddenly returned to normal and he nodded repeatedly.
At this moment, Zhang Yang suddenly said:
"Director Ding, can you help provide images of patients who have been diagnosed with 'pneumonia virus' infection in the past two years?"
< br>“What I want is, for example, if they were diagnosed with the pneumonia virus last year or the year before last, and then get the CT images this year, I want to see if there are any changes in the CT images after they were infected with the pneumonia virus!”
Ding Although the director was a little confused, he only hesitated for two seconds before agreeing.
"Okay, Mr. Zhang, don't worry, I will definitely cooperate with your request!"
"Well, thank you."
Zhang Yang exhaled slightly:
"Yes. Okay, Director Ding, what is the name of this year’s epidemic of pneumonia?”
“Bexilon”
"Okay!"
After chatting with Director Ding in the hospital for almost half an hour, Zhang Yang said goodbye and left after getting the information he wanted.
When he returned to the office, his eyes became solemn again, truly realizing the huge crisis brought about by this matter!
If the "pneumonia virus" can really induce pulmonary nodules, if the pneumonia virus is really the cause of the increase in the incidence of "lung adenocarcinoma", then you must try your best to figure out why this happens!
You know, the pneumonia virus has not appeared before, but it was cured in the past. There are no side effects, let alone causing lung nodules and lung adenocarcinoma!
And now!
Why did the pneumonia virus cause pulmonary nodules in just three years?
Is it mutation and evolution?
Zhang Yang is unknown!
Next, he began to wait for the patient data from Director Ding. He needed more patient data to confirm this matter!
A week later, Director Ding compiled the imaging data of patients who had been admitted to the respiratory medicine department as outpatients or inpatients in the past three years. The results also confirmed Wei Tian's statement.
Three years later, 70% of patients who had coughs and had CT scans due to pneumonia virus infection had pulmonary nodules on their CT images!
Moreover, according to doctors’ visual inspection, the vast majority of pulmonary nodules are malignant nodules!
The cold data was placed on Zhang Yang’s desk, making him shudder.
All data show that in the past three years, there has been a high positive correlation between pneumonia virus and "pulmonary nodules" and lung adenocarcinoma!
Director Dai's guess may be right!
Wei Tian’s hypothesis may be right!
But!
But there was still a huge problem in his mind!
Since the pneumonia virus can really cause "lung adenocarcinoma", why have the "lung adenocarcinoma" data in other foreign regions not improved significantly?
Is it really a race issue? !
In other words, the "pneumonia virus" that has appeared in the past three years is particularly sensitive to East Asians? !
Zhang Yang was not sure, sitting in his office chair in disbelief.
At this moment, a clear voice suddenly sounded in his mind.
[Congratulations to the host, the second stage simulation node of the simulator has been activated. 】
Is the second stage simulation plot activated? !
Zhang Yang instantly thought of the Adelev Biological Laboratory in Norway in the plot!
Then enter the simulator, yes, a new simulatable node has appeared.
The name is….
Pneumonia virus!
