Researchers identified two genetic variations in the MAPT gene associated with sporadic amyotrophic lateral sclerosis (ALS) in the Chinese Han population. Patients with these variations were more prone to bulbar palsy and breathing difficulties than those with the wild-type genotype.
The study found that melatonin receptor 1 expression is significantly reduced in the caudal spinal nucleus, leading to an attenuated regulatory effect on pain. This breakthrough discovery has implications for understanding pain transmission and developing new treatments.
Researchers found contralateral needling at specific acupoints significantly promotes recovery of affected limb function in stroke patients. The study demonstrated superior therapeutic effects compared to conventional acupuncture.
