Wang Longqian and Wei Dongbiao took the modified remote-controlled aircraft and rushed to Lan Xingyi's alien base, Xishan Tomb No. 29. Pen? Interesting? Pavilion wWw. ｂiquge。 Halfway through, Wang Longqian suddenly woke up and asked Wei Dongbiao: "Lan Xingyi won't be at home today, right?" ”

"No, I've investigated it all, today is a normal working day, she has to go to class normally, how can she have time here?" Wei Dongbiao replied very confidently.

"Then will she take a leave of absence today?" Wang Longqian was still not at ease.

"No, Lan Xingyi has never asked for leave!" Wei Dongbiao confidently denied it again.

"Didn't take a leave of absence? How could you not have taken a leave of absence? Wang Longqian was a little surprised.

"She is an alien, what can she do, she doesn't need to visit relatives and friends, and she doesn't need to go to school and work, her routine is as accurate as a machine!"

"That's right!" Wang Longqian drove his car with confidence, and after a while, the two of them came to the small mountain bag outside Xishanfen Village, Wang Longqian immediately picked up the telescope and pointed at the No. 29 courtyard of Xishanfen, and saw that the gate was tightly locked. The two people began to assemble the instrument, in fact, the assembly was very simple, the aircraft was equipped with a battery, the camera was facing down, and the radiometer was installed. After the wireless device docking of the mobile phone and the computer, the data can be received. Wang Longqian let the plane try to take off and land on the ground a few times, everything was normal, and then he controlled the plane to fly steadily towards the No. 29 courtyard of Xishan Tomb, and Wei Dongbiao recorded while watching the data on the computer. Wang Long has a mobile phone above the latent remote control, and from the screen of the mobile phone, he can also stare at the scenery along the way and the changes in the data on the radiometer. The pixels of the camera are still very high, and the trees around the aircraft and the weeds on the ground can be clearly seen.

As soon as the plane flew thirty or forty meters, it immediately turned back, Wei Dongbiao poked his head out of the police car and asked vigilantly: "What's the matter, Director?" ”

"It's nothing! Are you sure Lan Xingyi went to class? Wang Lung asked suspiciously.

"I'm sure, didn't you just look through a telescope? The door is locked! ”

"That's right, you say, she shouldn't know how to do it, right?" Wang Longqian suddenly remembered the Pisces jade pendant.

"Doppelganger?" Wei Dongbiao asked suspiciously.

"Yes, it's just a person in two places at the same time! Do you remember the Pisces jade pendant that the deputy director mentioned to us before, if people can copy it, they won't be lacking in skills! ”

"She doesn't know how to doppelgänger!" Wei Dongbiao replied affirmatively.

"You know that?" Wang Longqian questioned.

"Well, of course I do! Do you remember the last time we were here? ”

"Of course I do!"

"Lan Xingyi stayed here that night, so on the monitoring probe of the community where she lived, she didn't appear all night!"

"Have you checked?" Wang Longqian asked in surprise.

"Hmm," Wei Dongbiao nodded. "I've been intrigued since the last time I saw those special features, so I've been keeping an eye on them!"

"I'm relieved!" Wang Longqian once again controlled the aircraft and flew towards the mansion where Lan Xingyi lived. In order to avoid being discovered by the locals, after the plane flew out of the tens of meters, Wang Longqian controlled the plane to climb urgently until it was invisible to the naked eye, and then crossed the country road and flew over the house. The plane descended slowly, and did not stop descending until the cracks in the eaves could be seen clearly on the camera. Wang Longqian first let the plane stay in the air for a period of time, Wei Dongbiao carefully observed the changes in the data on the radiometer, the eye-catching blue numbers did not move, and there was no alarm sound of strong radiation, and the two of them were somewhat disappointed. Wang Longqian continued to control the plane and drew several circles over the roof, but the data on the radiometer still did not change at all.

"This radiometer can't be broken, right? Why is there no movement at all! Wei Dongbiao complained.

"Who knows?"

"Then if it's broken, our trip will be in vain!" Wei Dongbiao said in disappointment.

"No, let's take that ray measuring instrument back and measure it!" Wang Longqian said easily.

"Test, will you test?" Wei Dongbiao asked rhetorically.

"Yes, you forgot, I studied physics, I specially asked Lei Yunxiao how to determine if the radiometer fails!"

"Oh? Looks like you've got a pretty good plan! Wei Dongbiao's face began to brighten. Then take it back and test it! ”

"Hmm," Wang Long submerged and controlled the aircraft back to the hill bag.

"How do you measure it?" Wei Dongbiao asked curiously.

"It's simple, in fact, our computer monitors and mobile phones have radiation, as long as the radiometer is close to the computer or mobile phone, there will be a reading!" Wang Longqian carefully pinched one of the legs of the aircraft, and slowly approached the computer display screen on the car, but there was no response at first, and when the measuring instrument was close to the display screen within ten centimeters, a sharp alarm suddenly sounded, and the number suddenly increased a lot. "See, the radiometer is fine!"

"It turns out that the computer display screen has such a big radiation!" Wei Dongbiao exclaimed in surprise.

"Yes, but it's only within ten centimeters, we can't get so close under normal circumstances, you see, it's twenty centimeters here, and there is no indication anymore!"

"Well, it seems that there is really no problem with this radiometer!"

"Maybe there's no radioactivity here!" Wang Longqian's face was a little relaxed. "Let's test again, and we can rest assured that there is no radioactivity!" After saying that, Wang Longqian controlled the aircraft and circled on the No. 29 house of Xishanfen for a long time, whether it was close or far away, the radiographic detector never responded, and finally the aircraft battery was exhausted or there was no indication, Wang Longqian had to control the aircraft to return home.

"It looks like this trip was in vain!" Wei Dongbiao said disappointedly.

"It can't be said that at least we have confirmed that Lan Xingyi's residence is not radioactive, which means that the aliens have not researched weapons of mass destruction so far, and we don't have to worry about this in the future!" Wang Longqian still feels good.

"It's a kind of self-consolation for you to think so!" Wei Dongbiao scoffed.

"That's not it, I think we've gained a lot this time!" Wang Longqian said very calmly.

"Big harvest?" Wei Dongbiao smiled.

"What I'm saying is true, you see, we used a drone to detect an alien base a few hundred meters away this time, although we didn't get data, but this reflects a kind of thinking of replacing human work with machines. In the future, when we investigate supernatural events, we can use this method! For example, to investigate water monsters, we can use unmanned submarines to drill in first: for example, to enter the murderous house to investigate ghosts, we can use robots to observe first; Another example is to enter some places where the situation is unknown, we can use drones to take aerial photos to make it clear! In case of any accidents, the loss is only a set of machines, and personal safety can be guaranteed! ”

"Haha, who can afford to produce so many medium-purpose machines for you?" Wei Dongbiao said with a smile.

"Of course, we can't let those toy companies produce machines for various purposes, buy them and modify them ourselves!" Wang Lung subtly depicts his own grand blueprint with great interest.

"Well, that's a good idea!" Wei Dongbiao was also said to be moved.

"Now it seems that Lan Xingyi's high-energy physics experiment can't pose a threat for the time being, let's investigate the others first!"

"Last time, we investigated Lan Xingyi's leukemia, and we didn't have time to let Mei Lin analyze how good it was!" Wei Dongbiao chattered while packing up his things.

"That's right, I patronized the plane two days ago, I forgot about it!" Wang Lung woke up like a dream, and the two of them sped up the sorting speed, and quickly sorted out the equipment and stuffed it into the police car and went to the capital.

After returning to the capital, Wang Longqian and Wei Dongbiao called Mei Lin over. Since the last time she got the monster corpse, Merlin was very grateful, and always wanted to say that she came over in time this time.

"Director Wang, is there anything good?" Merlin asked with a smile.

"Yes, there's an important question for your advice!" Wang Long saw that she was very interested, so he said in passing.

"What's the important question?" Merlin was anxious and asked bluntly.

"Do you know about leukemia?" Wang Longqian motioned for Mei Lin to sit down.

"Generally understood, but not professional!" Merlin said matter-of-factly.

"Then tell me what you know in general!"

"Leukemia is a malignant clonal disease of hematopoietic stem cells, which is caused by uncontrolled proliferation, dysfunction of differentiation, and obstruction of apoptosis of hematopoietic stem cells!"

"Wait, what is a malignant clonal disease of hematopoietic stem cells!" Wei Dongbiao hurriedly interrupted Mei Lin, which means that we don't understand what you said at all.

"Oh, then I'm talking about it in layman's terms!" Merlin immediately understood, and she smiled and said, "In our blood, there are white blood cells, red blood cells, and platelets, you know this, right?" ”

"Well, I know this, I was in junior high school!" Wei Dongbiao echoed like a primary school student.

"In fact, the white blood cells, red blood cells and platelets in our body do not live long, the longest red blood cells only have a lifespan of 120 days, and they have no offspring, and they die when they die! This requires the rest of our body to regularly make blood to compensate for the dead blood cells, and these other parts of the body are the bone marrow, which contains hematopoietic stem cells that grow, develop, proliferate, and differentiate into white blood cells, red blood cells, or platelets! ”

"Oh, it's these hematopoietic stem cells that have a problem!" Wei Dongbiao understands this.

"Well, yes!" Merlin said in an encouraging tone.

"So when will these hematopoietic stem cells make blood?"

"We are making blood all day and night, and we are most active when we are young, so it is best for us humans to lie in bed and sleep from 11 o'clock in the evening to 1 o'clock in the morning, so that the hematopoietic stem cells can go all out to make blood. Staying up late often will affect the function of hematopoietic stem cells, resulting in a pale face the next day! ”

"Can you get leukemia?" Wang Longqian asked worriedly.

"It's okay once or twice, but after a long time, it may be gone!" Merlin scares Wang Longqian.

"Then I'll have to work and rest on time!" Wang Lung said with a smile.

"The malignant clonal disease I just mentioned means that those hematopoietic cells do not grow and multiply according to human needs, but grow and reproduce endlessly and unrestricted!"

"Oh, it's the same as cancer and malignant tumors!" Wei Dongbiao should say peacefully.

"Well, yes! That's why leukemia is also called blood cancer! A large increase in the number of these cells can lead to anemia! ”

"No, these cells proliferate a lot, so there is more blood, why are you still anemic?" Wei Dongbiao was a little puzzled.

"I'm talking about hematopoietic stem cells proliferating in large numbers, but these cells don't differentiate into white blood cells, red blood cells, and platelets, but go directly into the bloodstream, so that there are fewer blood cells in the blood, and then there is anemia!"

"Well, I see, is there any cure?" After listening to the principle of leukemia, Wang Longqian hurriedly asked the key points.

"At present, the most effective treatment is bone marrow transplantation, because hematopoietic stem cells are in the bone marrow, leukemia is caused by abnormal proliferation of hematopoietic stem cells, as long as normal bone marrow cells are used to replace abnormal bone marrow cells to make blood, then leukemia will be cured!"

"Then it doesn't seem difficult to treat leukemia!" Wei Dongbiao said to himself.

"There's a problem with this treatment!"

"Difficult to match!" Wang Longqian said.

"That's right! The success rate of bone marrow matching is nearly 1 in 100,000! ”

"It's too hard!" Wei Dongbiao sighed.

"Yes, so some public welfare departments have called on the whole people to register bone marrow bank information!"

"Is donating bone marrow knocking out bones and sucking marrow?" Wei Dongbiao asked worriedly.

"Where is it so terrifying, just like donating blood, you can use it by extracting some hematopoietic stem cells from the blood!"

"That doesn't seem to be difficult!"

"Is there any other way than a bone marrow transplant?" Wang Lung dived and saw that this was not compatible with Lan Xingyi's recovery method, and hurriedly skipped this step.

"Then there is radiotherapy, which generally cannot be cured, but can only control the disease and prolong the survival time!" Merlin said with a sigh.

"Why can't it be cured?" Wang Longqian asked uneasily.

"Because the principle of radiotherapy for the treatment of leukemia and cancer is the same, that is, to kill those abnormal proliferating cells through the radioactivity of chemical elements, to ensure that they do not make trouble or try to make as little trouble, but there is still no way to inhibit the production of abnormal cells, so there is no way to cure it, only to control the disease and prolong life before the bone marrow matching is found!"

"Then there is no radiotherapy?" Wang Lung was pressing step by step.

"You can't say there isn't!" Merlene's tone loosened a little. "You have to know that the pathogenesis of leukemia is caused by the abnormal proliferation of bone marrow hematopoietic stem cells, and why it proliferates abnormally is because the genes in it have changed, and the genetic information in it has been wrong! For example, if you copy a phone number and make a mistake, can you get the correct number if you copy it wrong again? The odds are slim to none! A bone marrow transplant is like you copying the wrong phone number, and then you ask someone for the correct number. Radiation therapy is like you copying the wrong phone number, and then you want to copy the wrong number again! ”

"That's really unlikely! Is there any other treatment for leukemia? Wang Longqian asked.

"Over the years, some traditional Chinese medicine methods have also achieved some therapeutic results!"

"Traditional Chinese medicine?" Wang Longqian asked curiously.

"Well, it seems to be treating leukemia with arsenic!" Merlin said calmly.

"That arsenic is highly poisonous!" Wei Dongbiao said in surprise.

"Yes, control the dosage, poison can also be a good medicine!"

"Haha, doesn't the Chinese Book of Filial Piety say that if you have a disease, you should taste the medicine first! I wonder if these people who are not sick and take medicine have a problem with their brains, no wonder Lu Xun's madman diary will declare war on feudal etiquette! ”

"Yes, in this country with a splendid civilization of 5,000 years, my grandmother is sick, and if you want to be a filial son, you have to eat some arsenic first!" Merlin echoed.

"Is there any other cure for leukemia?" Wang Longqian always felt that the methods used at present were not similar to the recovery process of Lan Xingyi.

"No more!" Merlin was a little bored with the question.

"Is there a high-tech method that's being studied?" Wang Longqian still didn't give up.

"Yes!" Merlin replied reluctantly.

"Yes? What method? Wang Longqian immediately came to his senses.

"GMO!" Merlin said casually.

"GMO for people?" Wei Dongbiao asked in a very exaggerated tone.

"Don't you want a high-tech treatment, GMO should be the most high-tech treatment at the moment!"

"Can people be genetically modified?" Wei Dongbiao was still very surprised.

"Yes, if it's a living thing, it's genetically modified!" Merlin replied in the affirmative.

"So what do you say about the GMO method?" Wang Longqian quickly grasped the crux of the problem.

"Didn't you just say that leukemia is blood cancer? It's because the genes in the hematopoietic stem cells are wrong, and you just have to find a way to correct it! Merlin replied easily.

"How?"

"It's just to cut out the normal genes, put them in the virus, let the virus infect the cells that produce the error, and then replace the correct gene with it!"

"It's as simple as that?" Wang Longqian was a little unconvinced.

"It's as simple as that, the key is how to determine what the error is, what kind of virus carries the right gene, how to ensure that the virus only infects abnormal hematopoietic stem cells and does not affect normal cells, and how to replace them after infection! If these problems are solved, then leukemia patients can be genetically modified freely! ”

"That sounds complicated, too!" Wang Longqian was a little discouraged at this time.

"Yes, this is just an assumption, whether it can solve all the difficulties is still unknown, the US medical security department has completely banned the method of genetically modified therapy!"

"Why is it forbidden?" Wei Dongbiao asked suspiciously.

"There is a big difference between theory and practice, and although some people have improved their physical condition through genetically modified therapy, most of them still die, which puts a lot of pressure on the US medical safety department. So now they only allow research on genetically modified therapies and not clinical trials! ”

"Well, I see! Thank you very much Professor Mei for your wonderful analysis! Wang Longqian said politely.

"You're welcome!" Merlin also replied politely.

"Then let's talk about it here today!" After speaking, Wang Longqian and Wei Dongbiao sent Mei Lin out of the headquarters of the Central Bureau of Investigation and Statistics. Wei Dongbiao asked: "Do you think Lan Xingyi's situation is one of these treatments that Mei Lin said?" ”

"A bone marrow transplant is definitely impossible, and I haven't heard of her eating arsenic, on the surface, it looks like it's radiotherapy, but I think that genetically modified gene is more reliable!" Wang Longqian thought carefully and said.

"Are you saying that Lan Xingyi came to Earth and has the same principle as the cattle slaughter incident we investigated?"

"Well, but according to what Dr. Xu said, during Lan Xingyi's recovery, except for the abnormal effect of radiotherapy, she didn't see any abnormalities, so how did these genetically modified viruses get in?" Wang Longqian was still puzzled.
