Genetic Polymorphism rs6505162 in MicroRNA-423 May Not Be Associated with Susceptibility of Breast Cancer: A Systematic Review and Meta-Analysis.

Background: MicroRNA-423 (miR-423) rs6505162 polymorphism is found to be associated with breast cancer (BC) risk. However, the results were inconsistent. This study meta-analyzed the literature on possible association between rs6505162 polymorphism and BC risk.

Combined Effects of Plant Sterols with Low Ratio of n-6/n-3 Polyunsaturated Fatty Acids against Atherosclerosis in ApoE Mice.

The effects of low ratio of n-6/n-3 polyunsaturated fatty acids (PUFA) have been clarified against atherosclerosis. Increasing evidence indicated that plant sterols (PS) have a significant cholesterol-lowering effect. This study explored the effects of PS combined with n-6/n-3 (2:1) PUFA on atherosclerosis and investigated the possible mechanism.

Spatial Vulnerability of Network Systems under Spatially Local Hazards.

A hazard is often spatially local in a network system, but its impact can spread out through network topology and become global. To qualitatively and quantitatively assess the impact of spatially local hazards on network systems, this article develops a new spatial vulnerability model by taking into account hazard location, area covered by hazard, and impact of hazard (including direct impact and indirect impact), and proposes an absolute spatial vulnerability index (ASVI) and a relative spatial vulnerability index (RSVI). The relationship between the new model and some relevant traditional network properties is also analyzed.

[Adjuvant effects of Zhenyuan capsule on chronic heart failure: Meta-analysis].

To systematically review the adjuvant effects of Zhenyuan capsule on improving the cardiac function of patients with chronic heart failure. Databases including PubMed, EMbase, the Cochrane Library, CBM, CNKI, VIP and Wanfang Data were searched electronically from inception to October 2016 to collect randomized controlled trials (RCTs) about Zhenyuan capsule for adjuvant treatment of chronic heart failure. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies.

One step physically adsorbed coating of silica capillary with excellent stability for the separation of basic proteins by capillary zone electrophoresis.

The coating of capillary inner surface is considered to be an effective approach to suppress the adsorption of proteins on capillary inner surface in CE. However, most of coating materials reported are water-soluble, which may dissolve in BGE during the procedure of electrophoresis. In this study, a novel strategy for selection of physically coating materials has been illustrated to get coating layer with excellent stability using materials having poor solubility in commonly used solvents.

Mitofusin2 decreases intracellular cholesterol of oxidized LDL-induced foam cells from rat vascular smooth muscle cells.

Mitofusin2 (Mfn2) plays a pivotal role in the proliferation and apoptosis of vascular smooth muscle cells (VSMCs). The purpose of this study was to investigate the effects of Mfn2 on the trafficking of intracellular cholesterol in the foam cells derived from rat VSMCs (rVSMCs) and also to investigate the effects of Mfn2 on the expression of adenosine triphosphate-binding cassette subfamily A member 1 (ABCA1), adenosine triphosphate-binding cassette subfamily G member 1 (ABCG1) and peroxisome proliferator-activated receptor gamma (PPARγ). The rVSMCs were co-cultured with oxidized low density lipoprotein (LDL, 80 μg/mL) to produce foam cells and cholesterol accumulation in cells.

[tMfn2 gene transfer promotes vascular smooth-muscle cells apoptosis via activation of the mitochondrial cell death pathway].

Objective: To investigate the effect of tMfn2 gene transfer on promoting the apoptosis of vascular smooth-muscle cells (VSMCs).

Methods: VSMCs were infected by adenovirus-mediated tMfn2 (Adv-tMfn2) or adenovirus-mediated Mfn2 (Adv-Mfn2). FACS analysis, cell death ELISA and TUNEL staining were used to investigate the role of tMfn2 and Adv-Mfn2 gene transfer on VSMCs apoptosis.

[Development and applications of an auto-analyzing system for Model TJ-IV vector-cardiogram].

A new computer-assisted vector-cardiogram analyzing system Model TJ-IV developed based on Model TJ-III, has been using in the routine clinical work in order to evaluate its features and performances. The system employs a 586 computer with a CPU of 120 MHz, a special low-noise amplifier, a 12 bit A/D tranducer and the C language for programming. The examinations of 206 cases were performed and all the vector-cardiograms were analyzed by the computer system and by manipulative methods respectively.
