Early Follow-Up of Arthroscopic Latarjet Procedure with Screw or Suture-Button Fixation for Recurrent Anterior Shoulder Instability.

Objective: To evaluate the early clinical and radiographic results of arthroscopic Latarjet procedure using screw or suture-button fixation in patients with recurrent anterior shoulder dislocation.

Methods: Twelve patients who underwent arthroscopic Latarjet procedure between January 2015 and December 2018 at our institution were retrospectively studied. Data of the patients' history, including age, gender, side of affected arm, body mass index (BMI), and the number of dislocations since fist dislocation were collected.

Translation and validation of the Simplified Chinese version of Western Ontario Osteoarthritis of the Shoulder Index (WOOS).

To produce a cross-cultural adaptation and translation of the English version of the Western Ontario Osteoarthritis of the Shoulder index (WOOS) into Simplified Chinese and to validate its reliability, validity, and responsiveness.A total of 52 consecutive patients were included. The inclusion criteria were as follows: diagnosed to have primary shoulder osteoarthritis (OA) and referred to undergo conservative treatment, able to speak Chinese, and able to read Simplified Chinese.

Translation and validation of the simplified Chinese version of the anterior cruciate ligament-return to sport after injury (ACL-RSI).

Purpose: The aim of this study is to obtain a translation and adaptation of the anterior cruciate ligament-return to sport after injury (ACL-RSI) into simplified Chinese and validate the simplified Chinese version.

Methods: Translation and adaptation were performed according to the guidelines of the American Academy of Orthopaedic Surgeons Outcome Committee. A total of 122 patients who were diagnosed with an ACL injury and underwent primary arthroscopic anterior cruciate ligament reconstruction (ACLR) between 2015 and 2016 were included in this study.

Overexpression of mitofusin 2 inhibits reactive astrogliosis proliferation in vitro.

Astrocytes become activated in response to central nervous system (CNS) injury, and excessive astrogliosis is considered an impediment to axonal regeneration by forming glial scar. Mitofusin 2 (Mfn2), a key protein in mitochondrial network, has been reported to negatively regulate cell proliferation. The present study aimed to explore whether reactive astrogliosis could be suppressed by Mfn2 overexpression.

[The influence of oxygen partial pressure change and vascularization of rabbit wound through negative pressure wound therapy].

Objective: To investigate the effect of vacuum sealing drainage (VSD) on variation of oxygen partial pressure (PtO2) and vascularization.

Methods: The 12 cases of rabbit's wound models were undergoing the VSD (vacuum group, n = 6) or conventional therapy (conventional group, n = 6). Variation of PtO2 was measured by oxygen partial pressure admeasuring apparatus, expression of hypoxia inducible factor 1α (HIF-1α) mRNA was measured by real-time fluorescent quantitative PCR, content of vascular endothelial growth factor (VEGF) was measured by ELISA after tissue homogenate in 7 days.
