Efficacy and safety of baroreflex activation therapy for treatment of resistant hypertension: a systematic review and meta-analysis.

To provide definite evidence for the anti-hypertensive benefit of Baroreflex Activation Therapy (BAT) for resistant hypertension, we performed a systematic review and meta-analysis to evaluate the efficacy and safety of BAT. Electronic searches were conducted in PubMed, EMBASE, The Cochrane Library and Web of Science. Two reviewers independently determined the eligibility of studies and extracted the data.

[ISOLATION OF RAT PATELLAR TENDON STEM CELLS AND EFFECT OF MECHANICAL STRETCHING ON Sox-9 EXPRESSION].

Objective: To isolate the tendon stem cells (TSCs) from rat patellar tendon and to investigate the effect of mechanical stretching on the expression of Sox-9.

Methods: TSCs were isolated from Sprague Dawley rat (12 weeks old) patellar tendon by collagenase digestion and low density culture. The cell colony morphology and number were observed by crystal violet staining; the cell morphology was observed by inverted phase contrast microscope, and the immunophenotypes of mesenchymal stem cells (MSCs) were determined by flow cytometry.
