TRPC1/TRPC3 channels mediate lysophosphatidylcholine-induced apoptosis in cultured human coronary artery smooth muscles cells [PDF]
, 2016 溶血卵磷脂（lysophosphatidylcholine，lysoPC）是氧化低密度脂蛋白（oxidizedlow-densitylipoprotein，ox-LDL）的主要成分。早期的研究表明，lysoPC可诱导人冠状动脉平滑肌细胞（humancoronaryarterysmoothmusclecells，HCASMCs)凋亡，但具体机制尚不清楚。近期，我们通过细胞活力测定，流式细胞术，共聚焦显微镜及分子生物学手段对lysoPC作用的分子机制进行研究发现，lysoPC可引发细胞外钙离子内流 ...

Preparation andProperties of Fluorescent Gold Nanoclusters Functionalized Silk Biomaterials [PDF]
, 2016 家蚕蚕丝作为天然的蛋白质纤维，具有独特的力学性能、良好的生物相容性和可控的生物降解性，已被作为生物医学理想材料。然而，蚕丝材料作为生物医学材料植入体内后，进行体内的检测和追踪仍是目前一大难点。本研究通过共混荧光金纳米簇和丝素蛋白，制备可用于体内荧光成像的蚕丝材料（3维支架、薄膜、凝胶），为生物材料的体内成像提供了思路。本研究主要内容如下： 冷冻干燥法制备三维多孔荧光丝素蛋白/金簇复合支架。复合支架具有红色荧光，研究发现丝素蛋白/金簇混合溶液的pH会影响金簇的荧光强度，发射峰位和荧光效率 ...

The research of developing functional artery with collateral circulation in the ischemic hindlimb [PDF]
, 2016 1、背景与目的 随着社会的发展，血管方面疾病的发病率呈现日益增高的趋势。在众多血管疾病中动脉硬化闭塞症、血栓闭塞性脉管炎等这一类疾病均可能伴随出现下肢缺血的症状。其中手术治疗主要包括人造血管旁路移植、支架植入以及球囊成形术等，但血管移植通常会形成血栓而只有短期的通畅性，支架植入和血管成形术往往又会造成扩张部位的再狭窄。对于血管病变广泛而无法进行手术或腔内治疗的患者，就只能通过药物保守治疗，通常是采用扩血管、抗凝和抗血小板等方法来改善其血液供应，随着病程的发展，药物往往不能起到很好的效果 ...

Lessons learned from screening potential other effective area‐based conservation measures
Conservation Biology, EarlyView.Abstract Other effective area‐based conservation measures (OECMs) are sites that deliver effective biodiversity outcomes irrespective of their management objectives. These areas are widely expected to play an important role in efforts to protect 30% of Earth by 2030.
