Chapter 1162: How to be bright when you are born with beauty
All the questions that needed to be asked were asked, and Dr. Yuan couldn't get any more information out of him.

When it comes to identity determination, genetic testing is essential in the field of criminal investigation, as a definitive conclusion cannot be drawn based solely on pathological slides.

Dr. Yuan experienced firsthand what it meant to possess exceptional skills; he had only come to consult on some clinical issues. Little did he know that this pathology slide would lead to a complete reversal of the case.

If these doctors were to work in criminal investigation, they would all be brilliant detectives.

Wen Ruzheng asked, "Do you need to do genetic testing in our genetics lab?"

He was eager to know the results. Although he was very confident in his judgment, and Professor Yang had corroborated his conclusion, he still wanted to know what the final genetic test results would be.

"Our genetic testing is all done at the genetics laboratory of Nandu Medical University," Dr. Yuan replied.

This was Yang Ping's first time dealing with a forensic doctor, but he knew that many high-tech medical techniques had been applied to criminal investigation. For example, gene testing technology based on specific Y chromosome sites had been applied to criminal investigation, and this technology was very mature. It could use the suspect's hair, debris, bodily secretions, etc., to perform gene testing, quickly determine which family he came from, then determine his specific hometown, and finally, through social relationship methods, determine his final location.

This technology has helped the police solve many difficult cases, enabling the resolution of many previously unsolved cold cases.

For Yang Ping today, this was just a routine review of pathological slides, yet it uncovered a suspicious murder case that was almost perfectly planned. If the blood was intentionally injected, it was undoubtedly premeditated murder, and the perpetrator had already achieved their goal.

People live in this world, fighting and competing, not knowing what the true meaning is. Yang Ping couldn't help but feel a little sentimental.

Director Zhao praised Wen Ruzheng for his good performance today. Wen Ruzheng waved his hand politely and said that this was just normal performance. Differentiating the red blood cells of the two people was not a problem for him. Today it was just a piece of cake.

Actually, Wen Ruzheng was quite happy today. Identifying two different types of red blood cells from pathological slides is extremely difficult. Today, he was the first to get on the machine and completed the slide reading before Professor Yang, which demonstrated his ability.

If I finish reviewing the film after Professor Yang, even if I figure it out independently, I won't be able to fully demonstrate my abilities.

“Dr. Yuan, this matter is of great importance. We have another way to help you obtain more information. Our Digital Medicine Laboratory at Nandu Medical University has another artificial intelligence model that may be able to give you a lot of information based on this pathology slide,” Yang Ping suggested.

Dr. Yuan was certainly interested: "That would be great, but it would be too much trouble for you."

"No trouble at all. I just made an appointment with Director He over there today to take a look at their large model. If it's convenient for you, you can come with me," Yang Ping suggested. He was indeed going to Nandu Medical University later.

"I'll go too!" Wen Ruzheng also wanted to see what it was like.
-
Since the establishment of the large-scale artificial intelligence model in the Digital Medicine Laboratory of Nandu Medical University, the efficiency of experiments has improved a lot. Tasks that used to require a lot of manual work can now be solved quickly using this artificial intelligence model.

For example, regarding the gene blocking mechanism of the Y chromosome, with the special case of Tong Yongqian's mother's family as the research subject, a detailed comparison of the chromosome genes of each generation was made. Through artificial intelligence analysis, what used to be a year or even several years of work can now be completed in just a few days or even a few hours.

So, a few days later, the genetics lab deciphered several key pieces of information about the Y gene's blocking mechanism, and then used this model to try to suppress this mechanism in the K virus.

Similarly, with the help of artificial intelligence, they conducted transplantation experiments in a virtual environment and quickly found a successful transplantation method, which was then applied to clinical practice.

With the support of Yang Ping's foundation, the Digital Medicine Laboratory of Nandu Medical University assembled a large team of 10,000 people to develop the world's first true medical artificial intelligence model. This artificial intelligence model can be applied in many fields, greatly shortening the research time and reducing the workload of researchers.

To verify the effectiveness of this artificial intelligence model, Yang Ping, Wen Ruzheng, and Dr. Yuan brought the pathological slide to Nandu Medical University.

Director He had been waiting for a long time. When he met Yang Ping, he said, "Our artificial intelligence model is now the most useful medical model in the world. It is a true artificial intelligence model. It is based on digital humans and is not in the same league as other models."

"This is Dr. Wen Ruzheng from our pathology department, and this is Dr. Yuan, a forensic expert from the Provincial Public Security Department. We've come here today to use your artificial intelligence model to read a pathology slide," Yang Ping told Director He.

Director He patted his chest and assured him, "It's a piece of cake. Our AI model is now superior to most doctors in the world in reading images and pathology slides. It's top-notch. I've already fed it a lot of high-quality data. It can produce results for a pathology slide almost instantly. It relies on a supercomputer and has amazing computing power. You'll see in a moment."

Director He is being honest; he's not bragging, but the large model really is of this quality. After continuous refinement, it's now not far from its official release.

Everyone sat down in the office, and Director He immediately called over a PhD: "Put this pathological slide under our microscope, take a picture of it, and upload all the pictures for them to see."

"I never imagined that clinical medicine has developed to this extent!" Dr. Yuan exclaimed in amazement after listening to Director He's introduction.

There is very little interaction between the fields of forensic medicine and clinical medicine. It seems that more exchanges are needed in the future so that new technologies from clinical medicine can be used to develop forensic medicine.

"Professor Yang? You mean this artificial intelligence can recognize this pathology slide?" Wen Ruzheng asked with some skepticism.

Yang Ping smiled and said, "This should be a very simple matter for it. This is exactly its area of ​​expertise. Just wait and see the result. It will surprise you."

Wen Ruzheng was somewhat incredulous. If these machines were so powerful that they could analyze such complex pathological slides, all pathologists would be out of a job because their work could be replaced by artificial intelligence.

"It will take some time to collect photos temporarily, please wait a moment while I introduce you to the fields in which this model can be applied."

“Our model is different from other general AI models. We are a medical-specific model, based on our leading digital human technology. It contains a virtual human, which can provide a platform for many scientific research projects. For example, in drug trials, before conducting animal and clinical trials, we can first conduct simulations in a virtual environment. While these simulations cannot completely replicate human trials, they can simulate key parameters, significantly shortening the drug development cycle, avoiding detours, and saving time and money. Once we release it, pharmaceutical companies will definitely contact us frantically for cooperation.” “Furthermore, we can use it for disease diagnosis, reading images and pathological slides, and developing treatment plans, among other things.”

Dr. Yuan was very interested in this: "What role does it play in forensic medicine?"

"Aside from legal restrictions, the technological applications are extensive. For example, we can analyze the subtle clues left by criminal suspects, such as a single hair. We can use that hair to reconstruct a person's entire information, including their appearance, age, height, weight, eating habits, and whether they have any diseases. Of course, there's a certain probability involved, so it might not be a perfect match, but it's very close. If we connect to the national family gene database, we can automatically narrow down the suspects to a very small range," Director He said proudly.

Dr. Yuan was quite surprised: "Is it that amazing?"

"You'll see how powerful it is in a moment. It will be something you'll never forget. Just from this one pathological slide, it can analyze a lot of things and then deduce a lot more. Of course, some of these things may be considered unreliable in law, but they are reliable in science."

As Director He explained, he urged the doctoral students to hurry up, eager to show Yang Ping his large model. Yang Ping had visited once before to learn about this model, but at that time it was still in a very rough stage. Now it was different; after refinement and iteration, it was now very mature and stable.

Wen Ruzheng was unimpressed by Director He's boasting. Artificial intelligence has been quite popular in recent years, with all sorts of models emerging one after another. Almost anything is labeled with the title of "artificial intelligence." Many hospital operating rooms simply have a display screen with voice control for the lights and air conditioning, and that's called an "artificial intelligence operating room."

Therefore, Dr. Wen scoffed at these claims, saying they sounded very convincing, but in practice, they were nothing special.

A PhD student returned and reported: "The images of the pathology slides have been collected, and we are now ready to put them into the machine."

Meanwhile, the pathology slide has been returned to Dr. Yuan.

"Turn on the computer, quick!" Director He immediately instructed his assistant to open the terminal window of their model on a computer so that they could see the output of the model.

"Everyone, come closer and sit down," Director He instructed.

This computer has a very large screen with very high resolution; it's the main computer in this office.

Everyone crowded around, staring at the screen. Director He was giving instructions over the phone so that Yang Ping would know exactly what stage the other side was at, thus understanding the efficiency of their model in processing data.

Sure enough, Director He wasn't exaggerating at all. After the image was uploaded, the information was displayed on the screen in just over ten seconds.

"The red blood cells in the image come from two different people, making them allogeneic red blood cells. The red blood cells distributed in the central core of the thrombus are mostly from the woman, while the surrounding red blood cells are mostly from the man. The possible mechanism of thrombus formation is: after the injection of exogenous blood, small blood clots form, which aggregate and cause thrombus formation in the blood vessel. The woman is approximately 32 years old, and the man is 53 years old..."

Wen Ruzheng immediately sat up straight, breaking out in a cold sweat. Could this really be true? He had spent twenty minutes examining the pathology slides before daring to confirm them, and this thing could glean so much information in just a few seconds? He was afraid he would lose his job.

Dr. Yuan was so surprised that he couldn't speak for a long time. It could not only distinguish red blood cells, but also distinguish them from different genders, and even deduce their respective ages. The deceased was fifty-three years old, so what about this thirty-two-year-old woman? The deceased's lover was thirty-two years old.

Is it really that accurate? Is this science or just superstition?

Director He waved his hand: "This is nothing. If a drop of blood were used for genetic testing and its genetic analysis model were used, it could simulate a person's appearance, height, weight, and build. Of course, it may not be 100% accurate, but it wouldn't be far off."

real?fake?
However, this new technology is still an experimental product that has not been officially released, and no one can guarantee its accuracy. Dr. Yuan would not dare to use it to test serious matters such as solving cases.

"Director He, another day I'll pack up all the microscopic images of pathological slides from our pathology department and send them over. You can take them in; that would be my contribution to you. I'd really like to see its accuracy rate," Wen Ruzheng said, unconvinced.

Director He said, "Okay, its accuracy rate is certainly not as high as yours for now, but it definitely surpasses that of 99 percent of pathologists in the world."

Wen Ruzheng liked hearing this, but he would definitely have to see for himself how it turned out.

Comparing his work to artificial intelligence in interpreting pathology slides, Wen Ruzheng's competitive spirit flared up again. If he couldn't beat Professor Yang, could he not beat a machine?
A few days later, Dr. Yuan, accompanied by the captain of the city's criminal investigation team, arrived at Sanbo Hospital with a basket of fruit. Led by Director Zhao, they came to thank Yang Ping and Wen Ruzheng. This was because their genetic testing had confirmed that the blood clot did indeed consist of blood clots from both of them.

Finally, through investigation, it was confirmed that the other person's blood was the deceased's lover's own blood. Under interrogation, she confessed to the crime. She used a modified insulin pen to draw her own blood, let it stand for a few minutes, and then injected it into the deceased's abdominal vein, causing the deceased to die from thromboembolism. She thought she had done it perfectly and there could be no loopholes, but she was still exposed.

No matter how sophisticated the methods, they are transparent in the face of powerful technology. With the development of criminal investigation technology, the crime detection rate will become higher and higher in the future.

As long as criminals leave any clues, criminal investigators can use high technology to track and crack the case, eventually revealing the truth. No matter how sophisticated the crime, it is still a crime.

Wen Ruzheng was now smugly pleased with himself in his office. If it weren't for his keen eyesight, the criminal would have escaped successfully. He was truly a Sherlock Holmes.

But as I thought about it, something didn't seem right. Why did I ask him to send the pathology slides in the first place?
Wen Ru was thinking hard when Professor Yang mentioned something: "There seems to be a slight problem with the red blood cells in this picture?"

Could it be that Professor Yang has already identified two types of red blood cells in the image, but only needs pathological sections for confirmation? That seems unlikely. But if no abnormality was found in the red blood cells, then what abnormality could there be?

Sigh, I thought I discovered it first this time. It's like the saying, "Why did Heaven create both Zhuge Liang and Zhou Yu?"
