A small-scale clinical trial showed that injecting cord blood within a few days after stroke can help relieve brain damage and restore cognitive and motor skills.

According to a recent report by the British "New Scientist"magazine, researchers from institutions such as Duke University in the United States recruited 10 volunteers between the ages of 45 and 79 to participate in the trial ,after cerebral ischemic stroke,a newborn cord blood injection was received between days 10 and 10 days.

After three months of injections by the researchers, all patients improved their language skills, eyesight and exercise capacity, improved their ability to take care of themselves daily, and had no significant adverse effects.

The researchers said that this trial did not set up a control group, and the results must be treated with caution. However, after the volunteers received the treatment, their ability scores were higher than those of ordinary patients, indicating that they may have positive effects.

Previous studies have shown that injecting human cord blood into laboratory mice can help repair brain damage after stroke. Experimental mice that receive treatment recover faster, have higher survival rates, and have smaller areas of brain damage. This is because stem cells in cord blood can secrete special substances that promote brain cell growth and reduce inflammation

Researchers have embarked on a larger scale trial and set up a control group to further validate the efficacy of the therapy. At present, the main method for dealing with stroke is drug thrombolysis, but it needs to be performed within a few hours after the onset, and most patients cannot be treated in time.
