Objective: To observe the protective effect and mechanism of hydroxyl safflower yellow A(HSYA)from myocardial ischemia-reperfusion injury on human umbilical vein endothelial cells(HUVECs). Methods:HUVECs were treated with oxygen-glucose deprivation reperfusion(OGD/R) to simulate the ischemia reperfusion model, and cell counting kit-8 was used to detect the protective effect of different concentrations(1.2.–160 μmol/L)of HSYA on HUVECs after OGD/R. HSYA 80 μmol/L was used for follow-up experiments. The contents of inflammatory cytokines interleukin(IL)-18, IL-1β, monocyte chemotactic protein 1(MCP-1), tumor necrosis factor α(TNF-α) and IL-6 before and after administration were measured by enzyme-linked immunosorbent assay. The protein expressions of toll-like receptor, NOD-like receptor containing pyrin domain 3(NLRP3), gasdermin D(GSDMD) and GSDMD-N-terminal domain(GSDMD-N) before and after administration were detected by Western blot. NLRP3 inflammasome inhibitor cytokine release inhibitory drug 3 sodium salt(CRID3 sodium salt, also known as MCC950) and agonist were added, and the changes of NLRP3, cysteine-aspartic acid protease 1(Caspase-1), GSDMD and GSDMD-N protein expressions were detected by Western blot. Results: HSYA inhibited OGD/R-induced inflammation and significantly decreased the contents of inflammatory cytokines IL-18,IL-1β, MCP-1, TNF-α and IL-6(Prence of pyroptosis after OGD/R and reduce the expression of NLRP3,Caspase-1, GSDMD and GSDMD-N proteins(P<0.01). Conclusions: The protective effect of HSYA on HUVECs after OGD/R is related to down-regulating the expression of NLRP3 inflammasome and inhibiting pyroptosis.

高熵碳酸盐固溶体因其鲜艳的色彩可被应用于颜料领域,同时其较高的近红外反射率也有用作隔热材料的潜能。本实验采用水热法,通过改变单一组元Cu、Fe和Mn,保持其他4组元为MgCoNiZn不变,制备出3种五元等摩尔高熵碳酸盐固溶体。利用X射线衍射仪、扫描电子显微镜、紫外–可见–近红外分光光度计、CIE 1976 L*a*b*色度坐标、Kubelka-Munk函数分析等对所合成的陶瓷粉体的晶体结构、颜色性能、反射性能等进行表征。结果表明,3种五元素组合均形成了单相高熵碳酸盐,且随着Cu^(2.)、Fe^(2.)、Mn^(2.)半径逐渐增大,晶格常数相应增大。通过组元的改变可以调节高熵碳酸盐的颜色,第5组元为Fe^(2.)时呈橙红色,Cu^(2.)时呈灰绿色,Mn^(2.)时呈浅紫色,相应的禁带宽度值也逐渐增大,吸收边缘相应的发生蓝移。此外还测得3种样品在780~2.500 nm波段具有不同的近红外反射率,最高可达78.64%,有望在高反射隔热材料领域进行应用开发。

目的:探讨急性高强度间歇运动(high-intensity interval exercise,HIIE)和急性持续中等强度有氧运动(continuous moderate-intensity aerobic exercise,CMIAE)对超重个体冲突抑制功能的影响。方法:采取被试内设计,以超重个体(n=2.)为研究对象,采用行为测量和事件相关电位(event-related potential,ERP)技术,记录超重个体完成认知任务(Flanker任务)时的大脑活动变化,比较急性HIIE和CMIAE对超重个体冲突抑制功能行为表现和大脑活动特征的影响。结果:1)与安静对照条件和急性HIIE相比,急性CMIAE条件下Flanker任务P3振幅显著提高(P0.05);2.与安静对照条件和急性CMIAE相比,急性HIIE条件下Flanker任务反应时缩短(P0.05);3)Flanker任务正确率运动条件主效应不显著(P>0.05)。结论:1)急性HIIE和急性CMIAE运动对超重个体冲突抑制具有促进作用,但行为和神经电生理表现有所不同,急性CMIAE可增强超重个体大脑唤醒水平,而急性HIIE可能通过加速认知刷新速率提升冲突抑制表现,推测两种运动对超重个体冲突抑制的调控可能存在不同机制;2.由于本研究中HIIE方案时长更短,因此推测急性HIIE对于超重个体冲突抑制的促进可能是一种更为省时有效的运动方式。
