RESUMEN
Aim To explore the effect of boschniakia rossica polysaccharides ( BRPS ) on cardiomyocyte damage induced by hypoxia/reoxygenation (H/R) and its possible mechanism. Methods H/R was used to induce rat cardiomyocyte H9c2 to establish a cell inju¬ry model, and different doses of BRPS were used to treat H9c2 cells. ELISA method was used to detect the level of MDA and the activity of SOD and GSH-Px. Flow cytometry was used to detect the rate of apopto-sis. qRT-PCR was used to detect the expression of miR-302a-3p. anti-miR-NC and anti-miR-302a-3p were respectively transfected into H9c2 cells and then subjected to H/R treatment. miR-NC and miR-302a-3p mimics were respectively transfected into H9c2 cells and treated with 100 mg • L
RESUMEN
Dystonia is one kind of dyskinesia characterized by abnormal movement and/or posture caused by persistent or intermittent muscle contraction. It also has distinguished features of repeatability and modeling, and can be induced or aggravated by random movements. Dystonia caused by hereditary factors is named as primary dystonia. Currently, 28 phenotypes have already been found in primary dystonia. Development of genetic technology has largely promoted the discovery of genetic mechanisms. Even so, many patients still have different genetic and clinical features from these phenotypes. Diagnosis of primary dystonia is quite challenging. Clinical manifestations, imaging examinations, electromyography, gene testing and other examinations should be taken into account for systematic diagnosis. This article reviews the genetic progress and diagnostic strategies of primary dystonia, aimed at providing help for further clinical practice and scientific research.
