201 - One-shot deal

Ningyuan is still very cold today, and there are snowflakes in the sky.It was so cold that it could freeze Ma Guoqun's feet into third-degree frostbite within four hours.However, it was clearly outside, and the entrance of the nuclear medicine department of the Fourth Central Hospital was crowded with people.Many doctors and students from the Department of Imaging, Department of Nuclear Medicine, Department of Infectious Diseases, and School of Public Health Management who got the news gathered together.They were all very curious about the Gamma Knife plan this time—from a certain point of view, the nature of this treatment plan was the same as the 3D printing atlantoaxial spine replacement surgery performed by the Capital Association.Both are the first treatments to be performed on humans.Moreover, compared with atlantoaxial replacement surgery, the Gamma Knife solution is actually more difficult and risky.

Radiation is required to be in place at one time, while surgery can adjust the surgical plan as the process progresses.This alone puts the Gamma Knife plan at a distance from the replacement technique.One can be slowly adjusted and tried, while the other is a one-shot deal.What's more, the Gamma Knife solution was not even proposed by a hospital specializing in tumors or infectious diseases—it was a treatment plan proposed by a large comprehensive emergency center!
The nuclear medicine department was never going to be the flagship department of a large emergency center hospital.Even if the Fourth Central Hospital is a key point in the province, it is also a regional demonstration unit.However, the nuclear medicine department of the Fourth Hospital is barely "nominated" in the annual rankings, and it can't even make it into the top five in the region.

If you want to use a metaphor, this feels like the Shanghai Mental Health Center is going to do atlantoaxial replacement surgery before the Capital Tongxie.Although the mental health center is also a comprehensive third-level hospital, and its strength is not too weak-they can still be ranked among the top [-] hospitals in the country.But this kind of difficult spinal surgery and neurosurgery is not their main business direction, and their department's "industry reputation" does not support them to do this kind of surgery rashly.

But big emergency centers are not the same as mental health centers after all.Yang Jianqiang's treatment is imperative, and he dare not delay at all.The attending doctor on duty at the nuclear medicine center dared not and was not qualified to do it.So first he called the deputy director, and when the deputy director heard about the treatment plan, he simply took the director out of the house.

Although Director Zhao Hua of the Nuclear Medicine Center has rich experience, emergency gamma knife treatment requires him to irradiate brain toxoplasma lesions under the condition of insufficient assessment.This kind of thing that he had never done before made him feel a little confused.In line with the principle of "the more you watch, the less panic you will feel", Director Zhao Hua made a few phone calls and called two professors from the School of Infectious Diseases and Parasites of Ningyuan Medical College.At the same time, Professor Zhang from the School of Military Preventive Medicine of the National Army University who is in the P4 laboratory of the School of Public Health of Ningyuan Medical College was invited to communicate. Although Professor Zhang is engaged in medical protection research, his doctoral supervisor is a well-known radiation sickness in the country. research specialist.It would be nice to ask someone to check the radiation plan!

Director Zhao Hua was calling for foreign aid, while Zhou Jun and the others were seeking support from industry experts as much as possible.Calls for help came one after another, and finally found Director Wang Hongjing, chairman of the Military Nuclear Medicine Professional Committee of the Fourth Army University.After a series of phone calls for help, the number of medical staff who decided to visit gradually rose to more than 50 now.

In this group of people, there are about a dozen professors and seven or eight associate professors. Except for Sun Lien, the one with the lowest degree is also a master's student.Sun Li'en, who had never been considered a top student, stood at the periphery of the crowd, his hands were shaking a little because the weather was too cold, or because he was overwhelmed by the arrogance of a top student.

"It's so lively?" Sun Li'en was shaking like a Parkinson's patient at the edge of the crowd. Director Wang Jianpei, who came to watch the excitement, saw this kid at a glance.Since Director Wang installed the takeaway software on his mobile phone, he eats mutton vermicelli soup three times a day, which is quite comfortable.Naturally, Sun Lien was also pleasing to the eye.Seeing that Sun Li'en was a little out of tune with the surrounding environment, he smiled and came over and patted him on the shoulder. "This place with a lot of people should be warm. Why did you freeze like this? Didn't you have time to eat?"

"Director Wang." Sun Li'en nodded quickly towards Wang Jianpei. According to his seniority, this is his future uncle, and he cannot be neglected in terms of etiquette.What's more, Director Wang has a great appetite. The last time he killed Sun Lien for almost 200 yuan in one meal.It would be very bad if he was found fault again. "I... I'm just a little nervous."

"Why are you nervous?" Wang Jianpei was a little puzzled, and then laughed, "It's not that you went on stage to suffer from the gamma knife. Just watch the excitement."

Sun Li'en replied honestly, "This treatment plan... I was talking too much to Director Zhou..."

"Director Zhou?" Wang Jianpei frowned and pondered for a while before realizing that Sun Lien was talking about Zhou Jun.Then Qi asked, "You came up with the idea of ​​gamma knife irradiating Toxoplasma gondii?"

Wang Jianpei's loud voice drifted far away along the cold north wind. Many experts present turned their heads and looked at Sun Li'en and Wang Jianpei curiously.In particular, there are more people who pay attention to Sun Lien. Everyone seems to want to see how many arms and legs the doctor who dares to use this kind of treatment has grown.

Sun Li'en was already nervous, but when he was stared at by these big shots, his hands trembled even more.But before it was his turn to justify a few words, a flatbed truck was pushed out from the passage next to the apron.Surrounded by many doctors in white coats, they propped up two white sheets on the flatbed cart with their hands, and followed the flatbed cart like a mobile tent.Zhou Jun was pushing the car at the rear, while Liu Pingchuan and others were holding white sheets—other nurses nervously monitored the cardiopulmonary monitor placed beside the bed.

Yang Jianqiang had a throat stuck in his mouth.When Sun Lien saw this moment, he felt a chill in his heart.

Could it be that the cerebral edema area at the base of Yang Jianqiang's skull has been squeezed to the brainstem, causing his breathing to be suppressed?

Taking a closer look, Sun Li'en felt relieved.Although the throat is inserted, there is no respirator commonly known as a "ball" connected to it.It seems that it should be a preparatory measure in advance to prevent the deterioration of the condition-once Yang Jianqiang shows symptoms of respiratory failure, this can at least buy a little time for throat insertion.

Mrs. Yang was at the front of the line.Like a Valkyrie in Norse mythology, she held up the umbrella in her hand like a long sword, and tried her best to block the wind and snow for the doctors behind her and her husband.

"You move very fast." A group of people walked to the gate of the Nuclear Medicine Center. Zhou Jun raised his head and saw Sun Li'en standing on the outermost side of the group at a glance.He waved at Sun Li'en, "What's the matter with the patient you diagnosed and the treatment plan you proposed? If something happens, you pretend to be fine?" Zhou Jun feigned anger, "Why don't you hurry up and push the bed?"

The senior brother is angry, so of course the junior brother has to behave.Sun Li'en ran to the bed in three steps at a time, and began to lower his head and push the bed.And the gazes of the surrounding academic bullies seem to be a little hotter.

Gamma Knife's radiation treatment plan has been finalized in the discussion in the conference room.Considering that there is only one chance for treatment, the experts of the Fourth Central Hospital did not adopt a relatively conservative total amount of radiation after extensively soliciting the opinions of professionals in the industry.Instead, a single-point radiation dose of 170 Gy/min in the abscess area, 80 Gy/min in the edema area, and a total radiation dose of 1000 Gy were adopted.

This amount of radiation is more than five times the prescribed dose for the general clinical treatment of brain tumors. For any patient, receiving such a large dose of radiation is extremely risky.Although Gamma Knife has the characteristics of accurate radiation area and little damage to other organs.However, it is still impossible to completely prevent the rest of the patient's tissue from being affected.And this effect will be more obvious especially under the huge amount of radiation.

For Yang Jianqiang, there are three most fatal risks of Gamma Knife.The first is that the radiation may have severely damaged his small intestinal villi, which is the main cause of most acute radiation sickness.The second is the delayed microvascular damage that may occur after high-dose radiation.When this damage occurs in the brain area, microvascular edema is likely to occur, leading to cerebral thrombosis or insufficient blood supply.The third risk is that high doses of radiation may cause brain tissue death.

Among the three risks, the first one can be avoided by precise control of the radiation impact area, and the second one can be avoided by strengthening anticoagulation after treatment.But the third risk is somewhat difficult to deal with.

The main means to avoid the third risk clinically is multiple exposures.Normal human brain tissue is actually more resistant to radiation than tumor tissue. Irradiation of about 80Gy can cause fatal damage to tumor tissue, but the impact on normal brain tissue is not so serious.Generally speaking, about six hours after irradiation, the brain tissue affected by the 80Gy dose of irradiation can begin to repair itself.Therefore, when treating large or multi-focal brain tumors, the radiation therapy course is generally divided into three days or even longer stages.Receive a certain amount of radiation every day, so as to protect normal tissues and kill tumors at the same time.

But Yang Jianqiang did not have this opportunity.It's not clear whether multiple doses of radiation are effective enough to kill Toxoplasma.And it's also unlikely that he'll have the opportunity to unpack the healing times.For him, there is only one chance to live or die.One radiation can suppress Toxoplasma gondii, and he may still survive.If the radiation is too strong and causes serious complications, or if the radiation is not strong enough and the Toxoplasma gondii continues to reproduce, Yang Jianqiang will die.

Sun Li'en, Zhou Jun and others sent Yang Jianqiang to the gamma knife bedside.Several young and strong male nurses worked together to lift him onto the bed.Leave the rest to the professionals.Sun Li'en and Zhou Jun got into the rest room outside the Gamma Knife treatment room together, and they drank tea together with a little restlessness-the hot water machine in the nuclear medicine department probably has a problem, the temperature of the water used to make tea is not even as good as that of the tea. The feet are hot.A pinch of tea leaves floated on the water, neither of them could drink it, nor would they not drink it.
