[Clinical characteristics of in-hospital cardiac arrest in emergency patients in Kashgar area and analysis of influencing factors on success rate of cardiopulmonary resuscitation].

Objective: To analyze the clinical characteristics of patients with emergency in-hospital cardiac arrest (IHCA) in Kashgar, Xinjiang Uygur Autonomous Region and the factors affecting the success rate of cardiopulmonary resuscitation.

Methods: Retrospectively selected patients who had cardiac arrest and cardiopulmonary resuscitation in the emergency department of the People's Hospital of 6 counties and cities in Kashgar area from January 2019 to January 2022. The clinical data of all patients were collected, including gender, age, major underlying diseases, the beginning and duration of resuscitation, the number of electric defibrillation acute physiology and chronic health evaluation II (APACHE II).

[RNAi-mediated knockdown of cyclooxygenase 2 inhibits the growth and migration of SaOS2 human osteosarcoma cells].

Objective: To explore the effects of a knockdown of cyclooxygenase 2 upon the growth and migration of SaOS2 cells.

Methods: We employed lentivirus mediated-RNA interference technology to knockdown the endogenous expression of gene COX-2 in human osteosarcoma cells (SaOS2) and analyzed their phenotypical changes. The effects of COX-2 silencing on the proliferation, cell cycle and migration of SaOS2 cells were assessed by thiazolyl blue tetrazolium bromide, flow cytometry and migration assays respectively.

[Short fusion and long fusion for degenerative lumbar scoliosis with lumbar stenosis].

Objective: To explore the indications, surgical techniques and prognostic factors of short fusion versus long fusion for elder patients with degenerative lumbar scoliosis.

Methods: Thirty-eight patients undergoing different kinds of surgical procedures for lumbar spinal scoliosis between June 2005 and October 2010 were recruited for this retrospective study. The mean patient age at surgery was 64.
