Chapter 239 Difficult task (second more)
Li Fengmin is an expert in the field of public health from a university in the central region. Professor Li Fengmin, who has worked in the Yunhe City Health Commission and the School of Public Health of Yunhe University for many years, has a very helpless problem-lumbar intervertebral disc herniation.

In the middle of the lumbar bones of the human body, in order to ensure joint movement and interconnection stability, the nucleus pulposus has evolved to balance the stress, the fibrous ring has evolved to absorb stress and limit spinal activities to maintain the spinal connection, and there is also a cartilage plate to protect the vertebrae.The nucleus pulposus, annulus fibrosus, and cartilage plate are combined together and are collectively referred to as the "lumbar intervertebral disc" tissue.

As people gradually get older, the water content of the nucleus pulposus will begin to show a significant downward trend.The water content of the nucleus pulposus will gradually drop from about 90% in infants to 70% or even lower in old age.With age, proteoglycan depolymerization in the nucleus pulposus increases, water gradually decreases, collagen thickens and is gradually replaced by fibrocartilage, which leads to a decrease in the size of the nucleus pulposus, and the annulus fibrosus cannot be as tight as it was in youth Encloses the nucleus pulposus.The change of force will make middle-aged and elderly people more prone to lumbar disc herniation than young people-the most intuitive change brought about by the shrinkage of the nucleus pulposus is the "shrinkage" of height.

But Professor Li Fengmin is unlucky because he basically has all the high-risk factors for lumbar disc herniation.He couldn't stop the growth of age, and the nature of his work required him to stand or sit for a long time. Both of Professor Li's parents had symptoms similar to lumbar disc herniation, but because there were not enough medical conditions at that time, both elderly people were in He died before being diagnosed.

The most troublesome thing is that, because of the frequent visits to the countryside for work, Professor Li spent most of his time riding on a bumpy off-road vehicle when he was young, and when he was in his thirties, he was involved in a car accident—just in the waist.

Aging, bad living habits, genetic factors, trauma.Under the combined effect of these four conditions, it would be a strange thing for Li Fengmin not to suffer from lumbar disc herniation.

Li Fengmin also suffered from stomach problems due to his long-term work attitude of going to the grassroots to understand the truth. After undergoing a gastric perforation repair operation 12 years ago, he finally couldn't bear it anymore.After repeated persuasion by colleagues and leaders, Lao Li was transferred to an administrative post.Occasionally, he will take the lead in conducting business and academic exchange activities between universities and institutions.

This time he came to Sanya, Li Fengmin was invited by Takeda Pharmaceutical.Lao Li, who had been working at the grassroots level all his life, couldn't figure out how Wutian thought of inviting him, but after thinking about it for a long time, the old man always felt that it would be good to go to Sanya for fun.Only then did I come to Sanya with my wife.

Lumbar disc herniation is difficult to cure, but various physical therapy can have some effect.Li Fengmin has been tightly locked up for a lifetime, and it is absolutely impossible for him to enjoy the SPA services provided by the hotel at his own expense.As for asking Takeda to pay - Li Fengmin himself could not accept it.If you have been clean and honest all your life, you can't be almost [-] and be put down by the sugar-coated bullets of capitalism, right?
After dinner, Lao Li felt a little uncomfortable in his waist.In the sub-venue in the morning, Lao Li was one of the main speakers. Apart from standing up and giving a speech, Lao Li had to sit for a long time for interviews.After several laps of uncomfortable walking, Li Fengmin decided to go for a swim—the lumbar spine is not easy to be stressed by the whole person in the water, and the symptoms can be relieved a little.

Swimming does help, and in fact, swimming is a great exercise for people with lumbar disc herniations.Of course, don’t swim butterfly. Butterfly requires a lot of strength in the waist. Although there are not many people who have a herniated lumbar disc and can swim butterfly, it is indeed a taboo.

Li Fengmin was swimming slowly in the water when he suddenly felt a strong radiating pain in his left leg.Pain from the outside of the left thigh all the way to the heel.The severe pain caused Li Fengmin to open his mouth unconsciously, but the pain was not at the right time - when he opened his mouth, he just dived underwater.

Open your mouth underwater, and water will pour in naturally.By the time Li Fengmin used his years of swimming experience in the Yangtze River to control his body and resurface, he had already choked on several saliva.

Li Fengmin's actions attracted the attention of the lifeguards. By the time the lifeguards rushed all the way to the vicinity, Comrade Li had already swam to the shore and started coughing while holding onto the edge of the pool.While coughing, he waved his hand to the lifeguard to indicate that he was fine. "Cough cough...I'm fine, cough cough, I accidentally choked on it."

After the lifeguard made sure that the old man was fine, he took the old man out of the water, let him sit on the shore to rest, and left.Other medical experts who came to prepare for first aid surrounded Li Fengmin.To be honest, a 68-year-old man choked on water, this kind of thing can be big or small.It may be okay to cough twice, or it may cause very serious consequences.All the doctors present were doctors who had seen countless similar cases. Since they all came, they should at least ask to make themselves feel at ease.

Although Sun Li'en and Hu Jia arrived first, they didn't go to the old man's side to inquire about the situation first.Sun Lien was still frowning, considering the meaning of "blood pressure is slowly dropping".Hu Jia, on the other hand, felt that with so many doctors who seemed to be at least at the director level, there was a high probability that he would not be of much use.

Sun Lien couldn't figure out what the slow drop in blood pressure meant after thinking about it.The old man choked on water before, and his body may be in a state of stress.In this state, blood pressure and heart rate will rise.Now that they are all on the shore and surrounded by people, it should be regarded as the relief of the stress state.Under this condition, blood pressure will definitely drop-but the recovery speed should be relatively fast.The word "slow" may not be used.

Does this mean that there is a problem with the old man's circulatory system?Sun Lien continued to think along this line of thought.There are three ways to control blood pressure in the human body. The first is baroreceptor regulation.In a normal human body, there are baroreceptors at the beginning of multiple arteries, and these receptors transmit reflexes to the vasomotor center in the medulla oblongata, thereby participating in the management of heartbeat and blood pressure.

The second is the volume pressure regulation mechanism. The human body will adjust the reabsorption efficiency of glomeruli to achieve the effect of regulating blood volume.The effect of regulating blood pressure is achieved through the adjustment of blood volume.

The third is the humoral regulation mechanism. The human body controls the relaxation and contraction of blood vessels by secreting specific hormones.

A slow drop in blood pressure may indicate that there is a problem with the receptors, or that there is a problem with the kidneys, or it may even be a problem with the cardiovascular receptors of the old man.

Sun Lien had a difficult time, and any of these three problems could be a serious illness.But to determine what is wrong with the old man, he must be sent to a large tertiary hospital as soon as possible to find out.

It's just... among this group of old experts who are probably almost [-] years old, snatch people out and send them to the hospital?Sun Lien trembled, this is not an easy job.
