复方丹参滴丸对老年冠心病患者血流变学、血脂及炎性反应递质的影响

目的：探究复方丹参滴丸对老年冠心病患者血流变学、血脂及炎性反应递质的影响。方法：选取2015年1月至2017年12月海南省人民医院收治的老年冠心病患者154例作为研究对象，按照随机数字表法随机分为对照组和观察组，每组77例。对照组采用常规西药治疗，观察组在此基础上加服复方丹参滴丸。比较治疗前后2组患者的血流变学、血脂、炎性反应递质和疗效。结果：观察组治疗有效率为92.21%，明显高于对照组治疗有效率79.22%，差异有统计学意义（P<0.05）。治疗后，2组总胆固醇（TC）、三酰甘油（TG）和低密度脂蛋白（LDL）水平均升高，差异有统计学意义（P<0.05），且观察组高于对照组，2组差异有统计学意义（P<0.05）。2组血流变学指标、高密度脂蛋白（HDL）、IL-6和TNF-α水平治疗后均降低（P<0.05），且观察组降低更明显，差异有统计学意义（P<0.05）。结论：复方丹参滴丸联合常规西药治疗冠心病患者，能够调节脂代谢，降低炎性反应，改善血流变学。     

石斛合剂对高脂高糖糖尿病大鼠心肌细胞Ca^2+代谢的影响

目的以糖尿病心肌病大鼠为研究对象,探讨石斛合剂对糖尿病心肌病心肌细胞Ca^2+代谢的影响。方法 Wistar大鼠24只,取5只作为正常组,余19只采用高脂高糖饮食联合链脲佐菌素腹腔注射进行糖尿病心肌病造模。成模后,随机分为模型组、二甲双胍组、石斛合剂组。二甲双胍组、石斛合剂组分别予二甲双胍、石斛合剂灌胃,正常组、模型组予生理盐水灌胃。4周后,测空腹血糖,取左心室心肌组织进行组织病理学观察和心肌细胞内游离钙(MyoCa^2+)浓度测定,Western blot法检测肌浆网Ca^2+-ATP酶(SERCA2a)、L型钙通道α1C亚单位蛋白(CACNA1C)蛋白表达,RT-PCR法测定SERCA2a mRNA表达。结果石斛合剂组心肌纤维较模型组、二甲双胍组排列整齐,断裂较少。与正常组比较,模型组血糖、心肌细胞MyoCa^2+含量和CACNA1C蛋白表达明显升高(P<0.01,P<0.05),SERCA2a mRNA和蛋白表达明显降低(P<0.01)。与模型组比较,石斛合剂组血糖、心肌细胞MyoCa^2+含量和CACNA1C蛋白表达明显降低(P<0.01,P<0.05),SERCA2a mRNA和蛋白表达明显升高(P<0.01,P<0.05);二甲双胍组血糖明显降低(P<0.01)。与二甲双胍组比较,石斛合剂组心肌细胞MyoCa^2+含量明显降低(P<0.01,P<0.05),血糖、SERCA2a mRNA和蛋白表达明显升高(P<0.05)。结论石斛合剂通过提高SERCA2a mRNA和蛋白表达,加快摄取Ca^2+的速率,降低细胞质Ca^2+负荷,缓解钙超载,最终达到维持糖尿病心肌病钙稳态的作用,有效维持心肌细胞的正常收缩舒张功能;其降糖作用不是预防糖尿病心肌病的主要机理,而在于抑制CACNA1C蛋白表达,抑制钙诱导钙释放过程。

Matrine,oxymatrine, and compound Kushen injection from the roots of Sophora flavescens: an overview of their anticancer activities

In the present review, we updated current information on the chemistry, contents, and anticancer properties of matrine (MT), oxymatrine (OMT), and compound Kushen injection (CKI). The anticancer properties were focused on lung, breast, and liver cancer cells because they are most susceptible. Sources of information were from Google, Google Scholar, PubMed, PubMed Central, Science Direct, PubChem, J-Stage, Directory of Open Access Journals (DOAJ), and China National Knowledge Infrastructure (CNKI). Reference was also made on botanical websites, such as Flora of China and World Flora Online. MT and OMT are dominant quinolizidine alkaloids from the roots of Sophora flavescens (Kushen) of the family Fabaceae. Against lung, breast, and liver cancer cells, MT and OMT inhibit cell proliferation; induce cell cycle arrest, apoptosis, and autophagy; restrict angiogenesis; and inhibit cell metastasis, invasion, and migration. The processes involve various molecular targets and signaling pathways. CKI is a traditional Chinese medicine (TCM) composed of root extracts of S. flavescens and Smilax glabra (Baituling) of the family Smilacaceae. With MT and OMT as major components, CKI has been approved for the treatment of cancer in China more than 20 years ago. In recent years, systematic reviews and meta-analysis have been undertaken to evaluate the anticancer effects of CKI. When CKI is used alone and in combination with chemotherapy of western medicine, there is much to be learned concerning their interactions besides their individual and integrated efficacy. Some perspectives of MT, OMT, and CKI are discussed, and their suggestions for future research are provided.

Pharmacological evaluation and mechanistic study of compound Xishu Granule in hepatocellular carcinoma

ObjectiveIn this study, we used HepG2 human hepatocellular carcinoma cells to study the effects of Compound Xishu Granule (CXG) on cell proliferation, apoptosis, and the cell cycle in vitro. We also used a xenograft tumor model to study the anti-tumor effects of CXG and related mechanisms in vivo.MethodsThe effect of CXG on cell viability was measured using Cell Counting Kit-8 and a colony formation assay. The effect of CXG on apoptosis and the cell cycle was analyzed using flow cytometry. The in vivo anti-tumor effect of CXG was assessed by measuring the volume change in xenograft tumors after drug administration. The CXG anti-tumor mechanism was studied using western blotting assay to detect cell cycle and apoptotic associated proteins.ResultsCXG suppressed HepG2 cell proliferation in a time- and dose-dependent manner in vitro. Colony formation experiments showed that CXG administration for 24 h significantly reduced HepG2 cell formations (P < .01). Flow cytometric analysis showed that CXG treatment for 48 h promoted apoptosis and blocked HepG2 cells in the G2/M phase. Western blotting results showed that Bax was significantly up-regulated and Bcl-2 was down-regulated in graft tumor tissues and HepG2 cells after CXG administration, which increased the Bax/Bcl-2 ratio. PLK1, CDC25C, CDK1, and Cyclin B1 expression were up-regulated. CXG had a good inhibitory effect on graft tumor growth in vivo.ConclusionCXG has good anti-tumor effects in vitro and in vivo. In vitro, CXG promoted HepG2 cell apoptosis and induced G2/M phase arrest. In vivo, CXG significantly inhibited graft tumor growth. The CXG mechanism in treating hepatocellular carcinoma may be that CXG can induce abnormal apoptotic and cell cycle associated protein expression, leading to mitotic catastrophe and apoptosis.
