The prevalence and risk factors of dislocation after primary total hip arthroplasty.

This study aimed to investigate the occurrence of dislocation and risk factors following primary total hip arthroplasty (THA). Retrospective analysis was done on the clinical data of 441patients with primary total hip arthroplasty who were admitted to our hospital between May 2018 and early December 2020. A total of 294 patients without posterior soft tissue repair were included as control group, and a total of 147 patients with repair of the short external rotator muscle and joint capsule were assigned to the repair group.

Methane detection using scattering material as the gas cell.

A compact methane (CH) detection system is presented and developed by using an alumina ceramic scattering material as its gas cell. Due to the material's high scattering performance, the optical path length of the gas cell at 1653.7 nm can reach 15.

Transcription factor PITX3 gene in Parkinson's disease.

PITX3 is a transcription factor important for the differentiation and survival of midbrain dopaminergic neurons during the development. Recent reports suggest that single nucleotide polymorphisms (SNP) in the gene may be associated with Parkinson's disease (PD). To verify their findings and to determine the nature of the association in a subset of our PD patients we have analyzed two PITX3 SNPs (rs2281983 and rs4919621) in 265 PD patients and compared them with 210 age-matched healthy controls.
