Stem cells can be transplanted into patients through veins, arteries and brain parenchyma. In recent years, researchers have used the in vivo model of ischemic stroke for stem cell therapy, and the results show that stem cell transplantation can achieve good therapeutic effect. The role of stem cells in the treatment process includes promoting the recovery of sensory motor function, promoting blood vessel formation and nerve regeneration, regulating inflammatory reaction and inducing oligodendrocyte formation.
Improve the quality of life: In 2006, Chinese scholars released the clinical research results of 50 cases of neural stem cell transplantation for the treatment of stroke sequelae. Before and 6 months after operation, the American Functional Independence Assessment Score was used to evaluate the patients' abilities in six aspects: activity ability, action ability, understanding and communication, and self-care ability. The results showed that after lumbar puncture and subarachnoid neural stem cell transplantation, the patients had good functional independence and improved their quality of life.
Improve physical function: In 2009, researchers used neural stem cell transplantation to treat 3 patients with sequelae of cerebral hemorrhage. Follow-up for 2-5 months after treatment. Among them, 3 patients had increased muscle strength and improved language function, 2 patients had improved intelligence and calculation ability, and 65,438+0 patients had improved swallowing ability.
The paper published in china medical engineering magazine 20 13 mentioned that 35 patients with stroke sequelae received three intravenous transplantation of mesenchymal stem cells. The evaluation of motor function after three months showed that the patient's sense, balance function and motor function of upper and lower limbs were improved, while the control group (without stem cell transplantation) had no obvious improvement after three months.
Literature shows that from 2006 to 20 13, Chinese scholars published hundreds of clinical studies on stem cell transplantation for the treatment of stroke sequelae. The overall research results show that stem cells have a positive therapeutic effect on stroke sequelae. In addition, there are related studies abroad in the same period, and the effect is good.
With the development of biomedicine, brand-new stem cell technology provides a new choice for the treatment of cerebral infarction. At present, China Beilian Century Stem Cells also carry out stem cell transplantation to improve the prognosis of cerebral infarction and its sequelae.
The cells needed for clinical treatment are obtained through special cell separation solution, extraction and purification; Through targeted injection or pathway, cells are imported into patients, and the damaged cells in the body are repaired by using the functions of self-replication and differentiation, so as to achieve the purpose of body function reconstruction.
After stem cell transplantation, the patient's high muscle tension was relieved, muscle strength was enhanced and gait was improved. With the passage of time, the patient's language ability has been restored and improved, and his cognitive ability and memory have also been greatly improved.
