Dexmedetomidine is considered an adjunct to local anaesthesia (LA) to prolong peripheral nerve block time. However, the results from a previous meta-analysis were not sufficient to support its use in paravertebral block (PVB). Therefore, we performed an updated meta-analysis to evaluate the efficacy of dexmedetomidine combined with LA in PVB.

Caveolin-3 (CAV3) is a muscle specific protein that plays an important role in maintaining muscle health and glucose homeostasis in vivo. A novel autosomal dominant form of LGMD-1C in humans is due to a P104L mutation within the coding sequence of the human CAV3 gene. The mechanism by which the LGMD-1C mutation leads to muscle weakness remains unknown.

Article Synopsis
  • Keloids are benign tumors of the skin, and their development may be influenced by human HLA status, but research on Chinese Han individuals has been limited.
  • The study analyzed HLA class I alleles in 192 keloid patients and 252 healthy controls using the PCR-SSP method, revealing significant differences in allele frequencies between the two groups.
  • High-risk haplotypes linked to keloids were identified, and the results suggest that specific HLA alleles could be genetic risk factors for developing keloids.
