"Oh, I see!"

Ye Zhenzhen was very interested in this project and asked, "Senior Nan, what is the effect after the designated release of genetically modified mosquitoes?"

Nan no Qiao: "The effect is unknown. ”

"Why? Did it fail?"

Nan Zhiqiao shook his head, "No, we won't know the specific effect until after the summer of the second year." ”

Ye Zhenzhen seemed to understand, and said: "Dengue fever is generally high in summer, and whether the mosquitoes released last year have any effect depends on the incidence of dengue fever in the area where it is released this year." ”

"Yes, my brain is spinning fast. Nan Zhiqiao lightly tapped Ye Zhenzhen's head standing beside her.

Nan Zhiqiao smiled with a smile and some ambiguous meaning, although the two had already determined the relationship between boyfriend and girlfriend, but in the laboratory, Nan Zhiqiao was very restrained and did not flirt.

Suddenly Nan Zhiqiao gently knocked her head, Ye Zhenzhen's face flew red, and she was busy looking for a stubble to cover up the past, "Those genetically modified mosquitoes seem to be called beneficial mosquitoes, also known as beneficial mosquitoes, according to the news, it should have an effect on preventing dengue fever outbreaks." ”

Nan Zhi pretended not to see the shyness on Ye Zhenzhen's face, and then said: "The beneficial mosquito you are talking about is not a genetically modified mosquito, the beneficial mosquito is a mosquito infected with Wolbachia bacteria, for mosquitoes carrying dengue virus, this bacterium is like a vaccine, which can stop the dengue virus from multiplying in the gas." The genetic modification project of mosquitoes mainly studies two genetically changed beneficial mosquitoes, classified according to sex, after the male beneficial mosquito and the normal mosquito mate, the offspring can not survive, and the female beneficial mosquito and normal mosquito mate, the offspring will not be able to transmit dengue fever. ”

"Sounds like it's going to work. Ye Zhenzhen was a little worried, "However, if male mosquitoes are sterilized and thrown into the natural environment, will it affect the ecological balance?"

Nan Zhiqiao frowned slightly, "This is also what the researchers are worried about, so at the beginning, it was only a fixed-point launch, and after a period of observation, it was decided whether to promote it on a large scale." ”

Ye Zhenzhen has always been an inquisitive character, asking: "Will genetically modified mosquitoes run out of the designated area? And in addition to observing the incidence of dengue fever, how can we judge whether those beneficial mosquitoes have any effect? What impact will it have on the ecology? And how can we distinguish genetically modified mosquitoes from ordinary mosquitoes in nature?"

"As for the method of distinguishing genetically modified mosquitoes from ordinary mosquitoes in nature, at the beginning of the project, the researchers considered that in addition to genetic testing methods, the most convenient thing is to observe with the naked eye, so while modifying the relevant genes, the mosquito compound eye gene was changed to red, which is convenient for the researchers to observe with the naked eye. ”

"Oh, I see, it's like when Morgan was studying fruit flies. ”

"Morgan was a pioneer in genetics, and he was a great man when he was able to come up with those experiments when the theory and technology were just beginning, and now, the theory and technology are very mature, and using genes to change the properties of organisms is no longer something that can be described with half the effort. ”

"Oh, to the eyes of those who came before us, the technology we have now is like God's hands. ”

Nan Zhiqiao was slightly silent for two seconds, and sighed: "Hope is the hands of God, not the hands of demons. ”

Ye Zhenzhen understood what Nan Zhiqiao meant, he was worried that genetic modification technology would have a bad impact on the natural world, but technology is sometimes a double-edged sword, bringing benefits and harm.

Looking at Nan Zhiqiao's slightly frowning brows, Ye Zhenzhen just wanted to change the topic and comfort a few words, when suddenly, a mobile phone rang.

It's Minami Joe's cell phone ringtone.

The mobile phone is in Nan Zhiqiao's hand, looking at the caller ID, it is the housekeeper of the old house in the suburbs - Uncle Li.

Connected the phone, Uncle Li's hurried voice came from the end of the mobile phone: "Mr. Xiao Nan, Mr. Nan suddenly fainted and is now on his way to the hospital." ”

Before the housekeeper Uncle Li's words fell, Nan Zhiqiao had already stood up and rushed out of the office.

Ye Zhenzhen followed behind Nan Zhiqiao and also came out of the office, "Senior Nan, I'll go to the hospital with you." ”

Nan Zhiqiao stopped Ye Zhenzhen, "No, you are staying in the laboratory, what is the situation, I will call you, I may need you to do experiments." ”

Nan Zhiqiao said with words, sounding, as if he knew what was going to happen.

Ye Zhenzhen obeyed Nan Zhiqiao's arrangement, and watched Nan Zhiqiao drive out of the central compound by himself from the window of the laboratory.

——

Nan no Qiao almost arrived at the emergency room of JS Hospital with his grandfather's ambulance.

In the emergency room, Nan Lishan was lying on the emergency bed, the emergency doctor was doing an examination, the housekeeper Lao Li and two black-clothed people were standing anxiously aside, and there were a large number of reporters who rushed to the emergency room.

The hospitalization of the chairman of Nanmu Group is a big event that will affect the stock market!

Nan Zhiqiao instructed a man in black who was standing aside, "You go outside to block the reporter, I don't want any news about Chairman Nan's condition to leak out." ”

"Yes. ”

The man in black left, leaving only the doctors and nurses, Nan Zhiqiao and the housekeeper Lao Li in the emergency room.

Nan Zhiqiao stood in front of the hospital bed and leaned over to check on his grandfather Nan Lishan's condition.

Minami Lishan appears to be in a deep coma, his whole body is hot, his face and neck are flushed, his eyelids are opened, his conjunctiva is hyperemic, his stethoscope is auscultated, his heart sounds are dull, his heart rate is fast, his neck and legs are moved, and his range of motion is limited.

The emergency doctor saw Nan Zhiqiao bowing his head to check on his patient, and rushed away with some displeasure, "Family, please leave first." ”

Nan Zhiqiao was slightly stunned and explained, "I know the patient's medical history, and I will stay to help you make a diagnosis." ”

Nan Zhiqiao then asked Uncle Li, the housekeeper at the bedside, "Uncle Li, when did my grandfather start showing symptoms?" ”

The housekeeper Lao Li is a lean old man in his sixties, who has lived in the Nan family with Nan Lishan since he was a child, and when he saw that Mr. Nan suddenly fell ill, he was also very worried, and hurriedly replied: "Mr. Xiao Nan, after you leave work in the morning, Mr. Nan has a headache, I persuaded Mr. to find a doctor to come to the house to see, but the old man said that he was just tired, and he would be fine after resting for a while." When it was almost noon, I went to the old man's room and found Mr. Nan fainting by the bed. ”

After the housekeeper Lao Li finished speaking, Nan Zhiqiao said to the emergency doctor who was doing the examination: "The patient had a history of being bitten by ticks three days ago, coupled with the headache and meningeal irritation symptoms that appeared today, it is highly suspected that the patient is infected with tick-borne encephalitis virus." ”

The emergency doctor was startled, and the little nurse behind him took a step back in fright.

The emergency doctor asked, "You said the patient had forest encephalitis?"

The little nurse followed up and said, "Forest encephalitis! is it contagious, do you need to isolate and treat it?"
