"The plasma protein of this blood sample is very low, which will cause the colloidal osmotic pressure in the plasma to decrease, and a large amount of water in the blood will seep out from the blood vessels into the body, forming edema and water and sodium retention, generally this situation will occur in patients with severe glomerulonephritis, but people with this disease will be very weak, before you said that three people died at the scene of the crime, two adults, and one child, then there are two possibilities, either the murderer has accomplices, or the murderer is a very strong person, strong enough to kill three people even if he has such severe nephritis。 ”

"I didn't understand a word in the first half of the sentence, but I understood it later, and I can tell you for sure that there was only one person on the scene. Li Xian told me with certainty.

"Then the suspicious range is much smaller, judging from the value of plasma proteins, this person's nephritis has caused irreversible damage to the kidneys, the kidney failure is already very serious, the kidneys are no longer working properly, in order to remove metabolic waste products and excess electrolytes from the blood, he must now be doing hemodialysis, that is, artificial kidneys, and is probably waiting for a kidney replacement. ”

"Then let me summarize," Li Xian crossed his fingers and counted as he spoke, "The suspect has severe nephritis, has reached the level of kidney failure, needs regular dialysis, may be queuing for kidney replacement, and is physically strong, even if he is seriously ill, he has the ability to commit crimes independently." ”

I nodded, "That's right!"

"Smack!" Li Xian slapped his face, "Kidney replacement! It takes a lot of money to replace a kidney, and the motive for committing the crime is also there." ”

"The motive is your policeman's business, so I can't say. But I also want to remind you that the price of a kidney replacement is not low, this murderer's health is getting worse, in order to get together the money for a kidney replacement as soon as possible, he will soon commit another crime, you have to hurry up. ”

"Thank you so much," Li Xian took my hand and glanced at the name tag on my chest, "Doctor Du, right? You can be regarded as a great help to us, thank you very much." Don't worry, don't underestimate the ability of our police, you have narrowed the scope of the suspect's investigation so much at once, then if we can't solve the case in a short time, wouldn't it be too embarrassing?"

"Then I wish you a smooth case. ”

"When this case is solved, I will ask our leaders to send you a big pennant!"

"You're welcome. ”

A few days later, two police off-road vehicles flashed their lights and came to the door of the clinic with their flutes, and several policemen rubbed at the door for a long time, but they didn't come in.

I called Li Xian aside and asked him why he was here? Li Xian said that according to the clues I provided, they quickly caught the murderer, a fitness instructor who had kidney disease and was waiting for a kidney change. Today, in order to express my gratitude, a deputy director of the Municipal Public Security Bureau led a team to send a pennant and give me a long face.

He said, let me wait and talk to the deputy director first.

At this moment, the surrounding neighbors saw that there was a bustle and hurriedly gathered around.

"Well, what's going on?"

"I don't know, early in the morning, the police car blocked the door, I guess it's not a good thing. ”

"Don't be the clinic that kills people, right?"

"That's hard to say, no matter what, don't come to this clinic in the future. ”

"Cut, as if someone really came to see the patient, I opened a pharmacy across the street, and I have never seen any patients in this clinic seriously, but a few days ago a policeman came, stayed for a while and left. ”

Chinese people are like this, they like to watch the excitement, and they often think bad when they don't know the truth.

It wasn't until the crowd of onlookers stood on the inside and outside that Li Xian took out a big red pennant from the car and handed it to the deputy director. The deputy director solemnly handed over the pennant to me, with eight large gilded characters written on it - "Superb skills to help the police chase the murderer", and there was a line of small characters below: The Criminal Investigation Brigade of the Zhonghu City Public Security Bureau presented Dr. Du Lin of the Hemolysis Clinic.

I thought to myself, the leaders of these public security bureaus really have a way, for fear that the advertising effect will not be good, and they have to wait for the people to surround enough before they express their intentions.

Then there were all kinds of posing POSS photos, holding pennants, shaking hands, shooting alone, shooting with the deputy director, taking pictures with the deputy director and Li Xian and others, tossing for more than half an hour, and finally sending these officials away.

In the evening, Li Xian came to me again, saying that he was looking for me to drink, and I thought about it, if the business was really bad in the future, it would be a new way to generate income for the criminal police team to do some blood tests, so I agreed.

I thought he would take me to a high-end restaurant, but in fact, he drove a "plainclothes police car" (no paint, no lights) and pulled me to a food stall by Half Moon Lake in Beicheng, ordered peanuts and edamame, and a large plate of spicy crayfish, and then brought a whole case of big green stick beer.

"How much do you drink?" asked Li Xian as he opened the bottle with his teeth.

I wiped the dishes and chopsticks on the table with a tissue and said, "One pound." ”

"I'll go, I can drink it, but I can't accompany you with liquor today, and I can't get up tomorrow morning if I drink white, let's still make a whole beer!" he poured himself a glass as he said, "I'm too thirsty, I'll take a sip first." ”

"I'm talking about beer!" I said lightly.

"Poof......" Li Xian didn't hold back, a large sip of beer that had just been drunk in his mouth squirted out, I subconsciously raised the plate I was wiping in my hand, stretched out my arm to block Li Xian's mouth, and saved my clothes and the wine and food just served in time, but this sip of wine was not bad at all, and it all bounced back to Li Xian's face intact.

I took out a few tissues from the tissue box and handed them to Li Xian, "Here you go, wipe your face, waste." ”

"Waste of wine?"

"Waste of vegetables!"

"You're really funny, hehe......" Li Xian wiped his face as if he remembered something, "No, your reaction speed just now was a little bit unusual, I couldn't help but just squirt out of my mouth, and your plate was blocked in front of me, isn't this what martial arts novels say, 'last to come'?"

I picked up a peanut with my chopsticks and threw it into my mouth, chewing it and saying, " The nerve reaction time of ordinary people is half a second, that is, they receive information from the outside world from the brain, and then make a judgment, and then give orders to the limbs through the nervous system, and finally the limbs execute this command, this process takes about 0.4 to 0.5 seconds, professionally trained athletes can increase this number to 0.2 seconds, and the time from the 100-meter sprint world-class athletes to leave the starting block when they hear the starting gun is about 0.15 seconds, and my reaction speed is ...... "I swallow this mouthful of peanuts," 0.05 seconds. ”
