Chapter 184 culprits

The toxin he is looking for is a mixture of three chemicals, not a new poison or, to some extent, a new mixed poison.

Chen Qun suddenly understood why this toxin would harm people everywhere, but it was not found by toxicological examination. Most of the time, the dose was very low. It's very likely that some kind of drug or compound exists in the front of our eyes before it is found.

In other words, the arch criminal of this serious poisoning event should be a powder, spray or some perfume, which directly radiate into respiratory tract cells and cause genetic changes when entering the respiratory tract and chest of the human body.

Cesium, in particular, is a radioactive substance, which perfectly explains the cause of gene mutation.

When gold and cesium are combined with nucleic acids and other organic structures in cells, physical and chemical changes occur, leading to gene mutation, and finally to respiratory distress symptoms, leading to respiratory failure.

Chen Qun understood why the poisoning patients on the plane got sick one after another, which showed that the time of exposure to these chemicals was different. But these people have definitely been exposed to the same evil, that is, the source of poison, with different symptoms and reactions. It shows that the exposure dose is different, and the harm is also different.

Seeing this result, Chen Qun had a sense of helplessness. Mr. Huang and his initial prediction was accurate. It was a toxic gas poisoning, or even a special dust or drug poisoning.

It's just that the source of the poison that so many people are looking for is not sewage or industrial smog. The dosage is very small, and it's even more scattered everywhere, so it can't be found. Maybe the hospital had checked the things carried by the patients earlier, but it didn't detect the radioactive elements, so it missed the results.

Now it's really hard to find a place to break the iron shoes. It doesn't take much effort.

Cesium and sodium sulfide are not easy to trace, but gold is easy to trace. No matter industrial reagents or chemical supplies, gold is very rare. The most common gold in society are some gold objects, and the rest are some gold powder for artistic purposes.

All of a sudden, Chen Qun thought of the easiest way to find out the culprit. Just before quitting the system, we checked the sequencing of mutation gene detection in the laboratory. At this time, only more than 1000 genes were detected, and a quarter of the genes were blank. Naturally, we did not have the conditions for further scientific analysis.

Chen Qun goes back to the real world again, takes out the tablet computer sent by Zhou Lin, and carefully checks the surveillance video on the plane sent by Pacific Airlines on the screen.

This video has been checked by the emergency action team of Xiangyun hospital and airlines for a hundred times. It depicts the action track of several poisoned patients on the plane, most of whom have no cross contact with each other.

However, these patients should not have the same thing. After all, if there is a large-scale poisoning incident, both hospitals and airlines are bound to trace the similarities of these patients. If you don't have the same thing, you must have been to the same place.

Chen Qun believes that these basic knowledge will not be ignored by hospitals or airlines.

In the twinkling of an eye, Chen Qun rushes into Qi Hong's ward again, points to the picture on the notebook, and asks the girl Xueba.

"Qi Hong, we have been looking for the toxin on the patient, but we have not found it. It's just that they were exposed to a powerful and toxic chemical, such as pesticides or toxic gases, which caused respiratory diseases. But if you assume that this toxic gas comes from the same place, what do you think it is? This is where the airline found several patients. It's just the terminal. "

Qi Hong frowned slightly. "Do you mean the toxin comes from the terminal, not from the same place?"

Chen Qun laughed. "I think it is a particular kind of respiratory tract poisoning, or poisoning, such as aerosol or perfume. However, now we need to solve the problem of illness. We should not rush to find out what the toxin is

When he said that, he suddenly changed the subject.

"What do you think is most likely to cause gene mutation? My answer is radiation. "

Qi Hong chuckled, and his whole body overflowed with a kind of rare coquettishness. "Is that what you boys often say, superheroes? The rich rely on technology, and the poor rely on mutation. So I'm going to be a superhero, too? Why has this radioactive toxin not been detected in the past two days? "

Chen Qun's face showed the look of memory and said a case slowly.

"When I was in my hometown, I met a patient who love dressing up. She used fake perfume and mixed with a small amount of toxic chemicals, which caused her whole respiratory tract to burn and scarred, resulting in a series of diseases. Also in the toxicology test, there are no typical symptoms. Later, my colleague inadvertently said that it was only a fake that I made fun of her high-end perfume. I found the cause. It should be the same this time. "Qi Hong tilted his head, big eyes straight at him, "do you mean all patients have been exposed to radiation elements?"

"Yes, all the toxicological tests are done. Especially everything that's used for smelling or medicine. "

Chen Qun put forward a chance to cast a large area of the net.

"That's my share."

Qi Hong immediately volunteered.

Chen Qun laughed, "it's not you, it's us. I also know that if you can't sleep tonight, you are responsible for tracking down the video on the plane again to see what they have come into contact with the same things or places in the terminal. As for Ouyang Yang and I, we will check the gadgets and luggage on the patients again to see if they have the same things

At this point, Chen Qun suddenly patted his head and said: "I'm so stupid. We can use zebrafish for serum antibody test at the same time. I went to Mr. Liang and separated my serum to see if it could alleviate the respiratory failure caused by gene mutation. "

Without waiting for Qi Hong to answer, he ran out.

More than ten minutes later, Liang Shaoming heard Chen Qun's suggestion. He closed his lips two times, suddenly clenched his teeth, and explained carefully.

"We have not found the pathogenic toxin molecules, nor have we detected the specific structure of the diseased gene nucleic acid. Naturally, it is impossible to detect whether the patient's serum can be used in clinical rescue. But if it's used in pathological experiments, I think it's a good idea. "

Chen Qun's mouth is wide open. It seems that it's better to ask for oneself than for others. He also needs to see Qi Hong's detection findings, find out the three chemical molecular structures determined by the system, and give a reasonable pathological explanation.

"I'll get ready first."

Chen Qun immediately found an excuse to hide and exchange the zebrafish needed for pathological experiments and the mutant genes isolated by the system from the system space. Then he called Zhao Xue and asked her to send the zebrafish embryos and mutant genes to the hospital's pathology laboratory, and told her the lock code of the laboratory.
