BACKGROUND Oxidative stress is closely associated with hypertensive *** oxidative balance score(OBS)measures oxidative stress exposure from dietary and lifestyle *** objective of this study was to investigate the association between OBS and mortality in hypertensive *** This study included 7823 hypertensive patients from the National health and Nutrition Examination Survey(NHA-NES)*** models,including Cox regression,restricted cubic splines(RCS),Kaplan-Meier survival analysis,subgroup,and sensitivity analyses,were exploited to investigate the relationship between OBS and the risk of *** Controlling for all potential confounders,a significantly inverse association was observed between elevated OBS and all-cause[hazard ratio(HR)=0.90,95%CI:0.85-0.95]and cardiovascular mortality(HR=0.85,95%CI:0.75-0.95).With adjustment for covariates,significant associations between lifestyle OBS and mortality risks diminished,whereas associations between dietary OBS and these mortality risks remained robust(all-cause mortality:HR=0.91,95%CI:0.86-0.96;cardiovascular mortality:HR=0.85,95%CI:0.76-0.96).RCS demonstrated a linear relationship between OBS and all-cause and cardiovascular mortality risk(P_(nonlinear)=0.088 and P_(nonlinear)=0.447,respectively).Kaplan-Meier curves demonstrated that the mortality rate was lower with a high OBS(Phe consistency of the association was demonstrated in subgroup and sensitivity *** after stratification showed that among current drinkers,those with higher OBS had a lower risk of mortality compared with former or never *** In hypertensive individuals,there was a negative association between OBS and all-cause and cardiovascular *** hypertensive individuals,especially those currently drinking,to maintain high levels of OBS may be beneficial in improving their prognosis.

为了解长江口及其毗邻海域水体真菌群落的时空分布特征,通过真菌ITS rDNA绝对定量和其扩增子高通量测序,系统调查了2022年春季、夏季和秋季海域表层水和底层水中真菌丰度和群落结构差异。结果显示,相较于春季[表层:(1.38×10^(8)±3.02×10^(7))copies/L;底层:(1.71×10^(8)±3.78×10^(7))copies/L]和夏季[表层:(1.14×10^(8)±3.64×10^(7))copies/L;底层:(1.11×10^(8)±2.55×10^(7))copies/L],水体真菌丰度在秋季[表层:(3.02×10^(8)±6.09×10^(7))copies/L;底层:(2.56×10^(8)±3.61×10^(7))copies/L]显著增加;表层与底层水体间真菌丰度差异不显著,但表现出离岸衰减的分布格局。群落结构分析表明,海水真菌主要为子囊菌门(Ascomycota)的粪壳菌纲(Sordariomycetes),其相对丰度在秋季呈现明显升高。多样性结果显示,海水真菌群落存在明显的季节性差异;表层与底层海水真菌群落多样性呈现不一致,底层海水中真菌群落季节性更为明显。冗余分析(redundancy analysis,RDA)分析表明,该海域真菌群落变化主要受溶解氧和温度影响。上述研究结果阐明了长江口及其毗邻海域真菌丰度及群落多样性存在明显的时空分布差异,为今后进一步深入解析河口生态系统真菌的生态功能提供依据。

背景：磷酸钙骨水泥和药物微球都是很好的药物载体，那么在磷酸钙骨水泥中加入药物微球，能否达到双重缓释的特性，能否产生更有益的作用值得探讨。目的：观察复合抗肿瘤药物微球对自制可注射磷酸钙骨水泥理化性质的变化。设计、时间及地点：对比观察支架材料生物相容性实验，于2008—05—12／2008-06—05在华南理工大学材料学院教育部重点实验室完成。材料：可注射磷酸钙骨水泥粉末由华南理工大学叶建东教授提供，多柔比星由江苏恒瑞制药公司提供，多柔比星微球由华南理工大学任力教授馈赠，粒径40～60μm。方法：将2mL水加入5g骨水泥粉中，然后迅速将干燥的0．12多柔比星微球加入其中，搅拌均匀成糊状后推入预制磨具中制备成直径0．18cm，高1．12cm的柱状载微球骨水泥，两断端平行，打磨光滑平整，同时制备不载多柔比星的空白对照组、多柔比星原药对照组。主要观察指标：观察骨水泥固化时间、抗压强度及微结构改变。结果：与空白对照组比较，载入药物和微球后，骨水泥的固化时间明显延长（P〈0．05），抗压强度明显下降（P〈0．05），多柔比星药物微球与磷酸钙骨水泥粉末混合组下降更明显。电镜扫描示，药物复合后磷酸钙骨水泥大体结构无明显改变，而载入微球后磷酸钙骨水泥空隙明显增多、增大，孔径约为40μm，药物微球粒径较大，达40～60μm，结论：药物和微球载入骨水泥会使其强度降低，孔隙率增大，凝结时间延长。
