  Traditional Chinese medicine uses a systemic treatment approach,targeting multiple etiological factors simultaneously.Danhong injection (DHI),a very popular Chinese medicine injection composed of water-soluble extracts of Radix Salvia miltiorrhiza (Danshen) and Flos Carthamus tinctorius L.(Honghua),is reported to be effective for many cardiovascular conditions.The primary active ingredients of DHI,and their systemic and interrelated mechanism have not been evaluated in an established myocardial ischemia/reperfusion (MI/R) injury model.We identified the main active constituents in DHI,including hydroxysafflor yellow A (A),salvianolic acid B (B),and Danshensu (C),by HPLC fingerprint analysis and assessed their effect on I/R injury rats and cardiomyocytes.These 3 compounds and DHI all decreased the levels of IL-1,TNF-α,and MDA,and increased those of IL-10 and SOD activity in vivo and in vitro,and had anti-apoptotic effects,as shown by flow cytometric analysis and TUNEL assay.Moreover,these compounds increased phosphorylation of Akt and ERK1/2 in cardiomyocytes.Interestingly,we found A,B,and C,exerted prominent effect compared with two other ingredients on inhibiting inflammation,reducing oxidative stress,alleviating apoptosis through decreasing NF-κB level and increasing Nrf2 expression and lower caspase-3 activity,respectively.Compounds A,B,and C are the main active ingredients of DHI.Compound A exerted a more prominent anti-inflammatory effect than B and C,by decreasing NF-κB levels; compound B had more powerful anti-oxidative capacity than A and C,by increasing Nrf2 expression; and compound C had stronger anti-apoptotic ability than A and B,by lowering caspase-3 activity.Our results elucidate the mechanisms by which DHI protects against MI/R induced injury.

遮荫是一种较好的提高茶叶品质特别是夏秋茶品质的方法,本文比较了三种不同遮荫材料对春、夏、秋三季茶产量与品质的影响,结果表明:各种遮荫材料均能在一定程度上降低树冠面及叶片温度、光强等,提高空气相对湿度,从而改善了茶树生长的小环境.覆盖后各季茶树新梢的品质也均得到了一定程度的改善,主要表现为茶新梢的叶绿素含量、氮磷钾等养分含量、游离氨基酸总量显著增加;氨基酸组分如茶氨酸、谷氨酸、天冬氨酸等也均表现出增
