[Comparison of clinical efficacy of two different pin arrangements for external fixation of femoral neck fracture].

Objective: To retrospectively analyze the clinical efficacy of external fixation in the treatment of femoral neck fracture with two different pin layout.

Methods: From April 2000 to April 2018, 140 cases of femoral neck fracture were treated with closed reduction and percutaneous pin external fixation, among them 121 cases were followed up for more than 1 year, including 31 cases in traditional group, 12 males and 19 females, aged 45 to 74(65.4±8.

Effects and mechanism of epigallocatechin-3-gallate on apoptosis and mTOR/AKT/GSK-3β pathway in substantia nigra neurons in Parkinson rats.

The aim of this study is to investigate the protective effect of epigallocatechin-3-gallate (EGCG) on apoptosis and mTOR/AKT/GSK-3β pathway in substantia nigra neurons in 6-dopamine-induced Parkinson rats. A total of 30 healthy male SD rats were randomly divided into control group, the Parkinson model group, and Parkinson model+EGCG treatment group. The model and EGCG groups were injected into the right striatum with 6-OHDA to establish the Parkinson model, and the control group was injected with saline only.
