As Sun Jiaping was pushed to the ward, the crowd of onlookers also dispersed.

At this time, only Li Xiyang and Mrs. Liu were left in the security room.

Li Xiyang looked at the other side quietly, waiting for Mrs. Liu to speak.

It is absolutely impossible for a normal person to become like that, and his spirit must have been greatly stimulated.

According to Chen Xu's previous statement, this Mrs. Liu said that her son had been bitten by a dog.

This reason could not convince Li Xiyang.

He thought there must be some other reason.

And on the other side, Mrs. Liu's expression was complicated, and she opened her mouth several times and swallowed her words back.

There seems to be something unspeakable!

Li Xiyang said lightly, "Auntie, you have also seen your son's situation, if you really want to cure him, please cooperate with us." ”

Seeing that Mrs. Liu still didn't let go, Li Xiyang stood up and said, "Okay!" ”

"You have also read the examination report of the hospital, there is no problem at all, and please take your son back as soon as possible."

Seeing that Li Xiyang turned around to leave, Mrs. Liu was anxious, "Doctor, don't go, I said, I said!" ”

Then Mrs. Liu told a secret that had been hidden for many years.

Twenty-five years ago, Mrs. Liu's husband died of illness, and in order to live, she took her son to marry for the second time.

But who would have thought that before marriage, a husband who was like an honest man, would be a gambler and soon lose all his family property.

Life is poor, and the husband only knows how to eat and wait for death day by day.

Mrs. Liu had no choice but to go out to work by herself.

The son was left to his husband's care.

But who knew that the husband would beat the child as soon as he drank, and even put the child in a dog cage.

My son was beaten every day and was bitten by dogs.

Mrs. Liu sends money home every month and doesn't know about these things at all.

It wasn't until half a year later that a neighbor came into town and met her and told her about it.

She hurriedly went home and secretly ran out with the child.

But since then, the child has become very weird.

I don't sleep in a bed at night, I sleep in a dog cage.

This has been the case until now.

Originally, it was just a sleeping dog cage, and his temper was quite good.

From the age of twenty onwards, every once in a while, he will get sick.

When he was sick, he told people that he had rabies, and when others didn't believe him, he bit them.

Seizures have become more frequent over the years.

Mrs. Liu also took him to many hospitals, but she couldn't find the cause at all.

As for why he concealed this past, it was only because he didn't want to recall that painful experience.

Every time she recalled, Mrs. Liu's heart ached like a knife, and she felt that she was not worthy of being a mother.

"Woo woo, I hurt the child, it's all my fault!"

Mrs. Liu recalled the past and couldn't cry.

Li Xiyang sighed, no wonder Sun Jiaping became like this.

Being locked in a dog cage for half a year, let alone a child, you have to go crazy if you change to an adult!

"Your son is really not sick, but something is wrong here!" Li Xiyang pointed to his head.

"Huh?"

Mrs. Liu asked in a panic, "Doctor, can that still be treated?" ”

Li Xiyang said, "If you don't hide it, maybe it will be better if you take your son to the neuropsychiatric department to check it earlier." ”

Mrs. Liu's face was pale and annoyed.

After groaning slightly, Li Xiyang said again, "Now, it's not that it can't be cured, and I have already said the way just now!" ”

Hope surged up in Mrs. Liu's eyes again, "Doctor, what can you do?" ”

"Go under the knife!"

"Surgery?"

Mrs. Liu was stunned, "Doctor, where do you want to prescribe?" ”

"If there is a problem with the brain, of course you have to open your brain!"

"Huh?"

At the thought of having her head cut open, Mrs. Liu flinched.

Li Xiyang patiently explained, "Auntie, craniotomy is not as dangerous as you think, epilepsy should know, 70% of epilepsy is cured by craniotomy."

And your son is in a dangerous situation right now, because the mental disorder has caused abnormal brain neuronal discharge, and in the next five years, your son has an 80 probability of developing meningioma and schwannoma.

And even if he doesn't have a tumor, do you think he can live a normal life in his current state? ”

Mrs. Liu couldn't understand medical terms, but the last sentence hit her heart.

She is old and doesn't know how long she will live.

So how will her son survive?

In the past, because of her selfishness, her son had missed a chance to heal.

Right now, I'm afraid it's the last chance.

"Doctor, my son's life is up to you!"

……

In the operating room,

Li Hua frowned, while Chen Xu and Su Xintong looked at each other.

It is true that an epilepsy craniotomy is true, but to give a psychotic craniotomy, the three of them are unheard of.

"Dr. Li, are you really sure?"

Li Xiyang washed the patient's head with soapy water, and said, "In modern society, there are fewer treatments for mental illness and it takes a long time, but in the mid-20th century, the prefrontal lobotectomy of the brain has already provided a solution for mental illness.

In 1849, an American railroad worker was in an accident when he was penetrated through the head by an iron rod that entered under the cheekbone and went out above the brow bone.

And yet the worker is still alive!

The only misfortune is that after this person did not die, his temperament changed greatly.

From a quick-witted, flexible, amiable and polite foreman, he has become vulgar and rude, impatient with things, stubborn, willful, capricious and indecisive.

Later generations took out his skull and studied it, and found that his problem was that he lost the function of the prefrontal cortex, which made him lose his sensitivity to risk reward and punishment at the same time, and thus his personality changed drastically.

Correspondingly, as long as the abnormal neurons of the patient are removed, his personality can be changed, and the recognition of gentleness can become irritable, and the same can become gentle for irritable people. ”

Li Hua was speechless, theoretically yes.

But the success of each new surgery needs to be demonstrated and perfected through many experiments.

"Patella surgery isn't enough for you to play? You're going to create a new surgery again, have you thought about the consequences of a failed operation? ”

Li Xiyang shook his head, "It's not a new technique, there have been successful cases abroad." ”

And

Li Xiyang stared at the patient's brain, and the light screen flashed rapidly.

[Brain: alarm alarm, information feedback failure, abnormal tissue discharge]

[Abnormal neurons: curry to electricity, curry to electricity, electricity to electricity, Pikachu 100,000 volts, brothers give me restlessness]

[Scalp: I'm numb]

【……】

Such an interesting brain, Li Xiyang encountered it for the first time.

"Give phenobarbital 0.1g orally."

"Atropine 0.4 mg intramuscularly."

"Anesthesiologist prepares!"

As the anesthesia took effect, the neurons that had been active just now instantly wilted.

[What... What's the situation, suddenly so sleepy]

[Brothers, let's sleep first, wake up and continue... Continue to be irritable...]

【Huhu~】

The snoring sounded, and Li Xiyang quickly faced the three people.

"Xiao Su, the patient is in a flat lying position, pad the left shoulder with a sponge pad, and turn the head to the right 20°-40°."

"Chen Xu, open the images of DSA and MRI to determine the location of the anterior central gyrus, posterior gyrus, and central sulcus."

"Treated by Li, electrotherapy is initiated, and the cerebral cortical functional area is stimulated."

Li Hua didn't know what Li Xiyang was going to do, but since he was on the operating table, he had to obey the order of the chief surgeon.

Soon the electrotherapy device was activated.

Li Xiyang said, "0.5V voltage stimulates the posterior central gyrus." ”

"Increase 0.5V every ten seconds until 5V."

"The stimulation wave width is 2 ms, and the frequency is 60 times/s."

"Let's go!"

Li Hua did so, and then saw Li Xiyang quickly place small pieces of digital paper on each stimulus point and record them on the drawing.

Li Hua instantly understood that Li Xiyang was doing electrocortical tracography, and by observing the brain discharge phenomenon, he found out the location of the most excited neurons.

According to electrocortical tracing, it is generally believed that the area with the most frequent spikes during the attack is the location of the lesion.

Li Hua was shocked.

Prior to this, he heard that the Imperial Capital Third Hospital had introduced a horseshoe-shaped scaffold type cortical electrode, which is the world's top electrocortical electrodermography instrument that can be automatically traced.

Their first hospital did not have such advanced equipment, so many complex craniotomy operations could not be performed at all.

And Li Xiyang actually came up with a way to stimulate the patient's cerebral cortex with electrotherapy, and manually completed the accurate tracing.

What kind of evil is this guy!!
