Nature: CAR-T can last for 10 years!

On February 2, local time, Nature published an important paper on CAR-T therapy. The team led by Professor Carl June, a world-renowned car-T therapy expert, has found through long-term research that the effect of CAR-T therapy can last for 10 years.

The researchers first confirmed that CAR-T cells are still present in the patients after 10 years of treatment. However, the composition of these cells has changed significantly over time. In the early stages of treatment, CAR-T cells are predominantly CD8-positive T cells. They have a lethal effect, killing cancerous cells and treating cancer. After a few years, most of the CAR-T cells convert to CD4-positive T cells. These cells are generally referred to as "helper T cells" and play a major role in assisting and guiding. In two patients, CD4-positive T cells can account for 97% to 99% of the years after receiving treatment. "Based on these results, we can now conclude that CAR-T therapy can really cure cancer."

The whole network is challenging the "green waist"

Experts urgently remind: waist injuries

After the dance poetry drama "Only This Green" was broadcast at the Spring Festival Gala, the whole network was imitating and challenging the "green waist". Dr. Wang Wei, deputy chief physician of the Department of Spine Surgery of Wuhan Fourth Hospital, introduced that making a "green waist" action requires strong waist and abdomen strength. Ordinary people who have not been professionally trained can easily cause waist injuries when imitating this movement. This includes excessive posterior extension down pressure of the lumbar region, which results in increased local stress in the lumbar region and additional squeezing at the posterior margin of the intervertebral disc, which may lead to the breakdown of the local fibrous ring. Further increased pressure causes the nucleus pulposus to protrude from the broken fibrous ring. If the protruding nucleus pulposus compresses the peripheral nerves, it can lead to a herniated disc. This action will also cause the joints of the joints at the back of the vertebral body to be damaged by great pressure, which will lead to lumbar instability and sequelae in the long run. For adolescents who are in the growth and development period, improper imitation will also lead to increased local stress in the lumbar spine, which may cause bone rupture in the lumbar isthmus, resulting in long-term low back pain and even lumbar spondylolisthesis.
