1Brazilin from Caesalpinia sappan heartwood and its pharmacological activities:A review显示文摘Caesalpinia sappan L.(CS) is a plant of Leguminosae family,commonly known as Brazil or Sappan wood.CS is distributed in Southeast Asia and its dried heartwood has been used as traditional ingredient of food or beverages and has a wide variety of medicinal properties.Higher extraction yield of CS wood was achieved with 95% ethanol for 2 h.Chemical constituent's investigation of sappan wood resulled in the isolation of various structural types of phenolic components including one xanihone,one coumarin,three chalcones,two flavones three homoisoflavonoids and brazilin.Brazilin[(6a S-cis)-7,11b-dihydrobcnz[b]indeno[1.2-d]pyran-3.6a.9.10(6H)- tetroll.a major and active compound found in CS heartwood.Most of the folkloric uses of brazilin were validated by the scientific studies such as antioxidant,antibacterial,anti-inflammatory,anti-photoaging.hypoglycemic,vasorelaxant,hepatoproteetive and anti-acne activity.CS heartwood extract is safe and did not produce any acute or subacute toxicity in both male and female rats.Brazilin is the safe natural compound having potential to develop as a medicinal compound with application in food,beverage,cosmetics and pharmaceutical industries to screen its clinical use in modern medicine.The information gained could provide the important and potential approach for pharmaceutical researcher to implicate the knowledge of brazilin in the formulation of new drug and to reveal therapeutic and gaps requiring future research opportunities.More studies are needed to evaluate the potential application of brazilin as preservative and coloring agent in food processing industries.Nilesh P Nirmal Mithun S Rajput Rangabhatla G.S.V.Prasad Mehraj Ahmad 2015Asian Pacific Journal of Tropical Medicine2015,8,6:14
2新型冠状病毒肺炎及其心血管效应:流行病学研究的系统综述显示文摘少数新型冠状病毒肺炎(新冠肺炎)患者病情严重,其特征是炎症、微血管损伤和凝血障碍,可能导致心肌损伤、静脉血栓栓塞症(venous thromboembolism, VTE)和动脉闭塞事件。有心血管病危险因素或既往有心血管病的个体可能面临更大的风险。目的:评估各种环境(包括社区、疗养院和医院)中,与新冠肺炎疑似或确诊病例相关的既往存在心血管合并症的患病率。研究者还评估了疑似或确诊新冠肺炎患者随后发生心血管并发症和临床事件的性质和发生率。Pellicori P Doolub G Wong CM Lee KS Mangion K Ahmad M Berry C Squire I Lambiase PD Lyon A McCon-nachie A Taylor RS Cleland JG 刘青(摘译) 练桂丽(审校) 2021中华高血压杂志2021,29,5:3
