Stroke has always been a disease that affects people's physical and mental health and quality of life. Many stroke patients fail to get timely treatment, leading to irreversible brain cell damage and causing hemiplegia. And in China, the incidence of stroke is increasing. So, is there any way to get the patients who are affected by the stroke to return to normal? It is understood that Professor Shen Jun from the Department of Radiology of Sun Yat-sen Memorial Hospital of Sun Yat-sen University and his team have recently done research on stem cell transplantation for stroke. Can this technology help the stroke?

Less than one-third of the treatment of cerebral infarction in China can be treated in time

Stroke has been the highest mortality rate in China and the world. The level of medical health in China is slightly worse than that in developed countries such as Europe and the United States. Therefore, the incidence of stroke in China is also relatively high.

In addition, after the occurrence of cerebral infarction within 3.5 hours, the first time of treatment is required. If you miss this time, the necrotic tissue of the cerebral infarction can no longer be recovered, which will lead to dysfunction or even disability of the patient's limbs. If the condition is more serious, cerebral infarction may even lead to death.

It is a pity that at present, China has conditions for almost 1/3 of people with cerebral infarction, and can reach the hospital for emergency treatment within 3.5 hours after the onset of illness. Most people will be after this time. Therefore, the patient's treatment effect is relatively poor, most patients have to use neuroprotection and later rehabilitation. These treatments can only partially restore the dysfunction caused by cerebral infarction, leading to life unable to take care of themselves, requiring more care than people, and placing a heavy burden on families and families.

Two major advantages of stem cell transplantation are expected to break the treatment of cerebral infarction

Stem cells are a very popular treatment technique in recent years. So what is the role of stem cell transplantation in the application of cerebral infarction? We must first understand what stem cells are.

Professor Shen Jun explained that stem cells are a relatively unique cell. Simply put, such cells can differentiate into a variety of other cells, such as nerve cells, neurons, glial cells, and many other cells that the body needs.

Therefore, if the stem cells are transplanted into the brain, it can become nerve cells, glial cells or neurons, so that the necrotic tissue caused by cerebral infarction can be replaced to achieve the desired therapeutic effect.

At present, the first-line treatment for cerebral infarction is to perform thrombolysis within 3.5 hours to relieve the occlusion of blood vessels leading to cerebral infarction. But this means is very strict with time. Stem cell transplantation is not subject to this limitation. It does not have such a time limit requirement and can be applied in the acute phase or in the later phase. For example, some people can't get thrombolytic therapy, but they can also do stem cell therapy.

Second, stem cell transplantation can solve the problem of fundamental nerve tissue necrosis caused by cerebral infarction. Because the nerve tissue is necrotic after cerebral infarction, the neurons in the brain and glial cells disappear. If you transplant stem cells into your brain, it can become these cells and act as a substitute. It is necessary to know that the various movements and instructions of the human body are commanded by the neurons and can be transmitted to the body in order to carry out activities.

So the advantage of stem cells is that there are two points. Professor Shen Jun concluded that one is not limited by time. If you missed 3.5 hours, you can also do stem cell therapy. The other is that you can truly differentiate into neurons. This is the best treatment for cells that replace the brain tissue.
