AIM:To investigate the effect of TSM tablet on rat' s atherosclerotic model' s endothelial cell and explore the mechanism of it.METHODS:Fifty Wistar rats were randomly assigned into five groups:control group,model group,Simvastatin group,TSM high group,TSM low group.All groups were fed with high fat diet and vitamin D_3 except for control group to set up atherosclerosis model.After 12 weeks we detected circle endothelial cell,angiotensin Ⅱ and electron microscopy morphology of arteries.RESULTS:Level of circulating enthelia cell(CEC)and Ang Ⅱ in model rats were significantly higher.TSM can reduce level of the CEC and Ang Ⅱ.Model group rat' s artery endothelial cells were severely damaged under electron microscopy;rat's artery endothelial cells in TSM group were basically intact and its internal elastic membrane was unbroken on it thickness was even,without significant lesion.CONCLUSION:TSM by reducing the number of CEC,the level of Ang Ⅱ used for experimental atherosclerotic endothelial cell in rats has the protective effect.

Heat shock protein 27 ( HSP27 ) is an endogenous protein that plays an important role in a great variety of physio-logical and pathological processes. It can express a large number under body stress conditions. Recent studies have shown estro-gen upregulates the expression of HSP27 through a number of ways, playing a perfect “triple protection” role. In the early stage of atherosclerosis, estrogen induces the phosphorylation of HSP27 via PI3K/Akt signaling pathway. Phosphorylation of HSP27 can resist the injury of vascular endothelial cells( VECs) through an antioxidant and anti-apoptotic pathway as well as the inhibition of cytochrome C. In the stage of forming foam cells, estrogen induces the expression and release of HSP27 from mac-rophages by stimulating the estrogen receptor β ( ERβ) , then HSP27 inhibits the LDL uptake and the release of proinflammato-ry cytokine by binding scavenger receptor A ( SR-A) . During the proliferation and migration of vascular smooth muscle cells ( VSMCs) , estrogen induces estrogen receptor α ( ERα) and protein phosphatase 2 ( PP2A) to form a complex that enhances the activity of PP2A, then it can lead to the dephosphorylation of HSP27 and finally inhibit cells proliferation and migration. In summary, the anti-atherosclerotic effect of estrogen is closely re-lated to the role of HSP27. Given the side effects of estrogen re-placement therapy( MHT) , regulating HSP27 may provide a no-vel therapy for the prevention and treatment of cardiovascular dis-eases in menopausal women clinically.

Autophagy is a common phenomenon which widely ex-ists in eukaryotic cells. Researches have shown that autophagy plays a critical role in maintaining cellular hemostasis, cell com-ponents update and keeping a normal physiological state. In re-cent years, the study has found that autophagy is closely related to the growth, the development of cardiovascular diseases and tumors. Further studies show that in different pathological condi-tions, autophagy could both promote angiogenesis and inhibit the formation of blood vessels. Therefore, it is particularly critical to elucidate the mechanisms of autophagy in the regulation of angio-genesis in different pathological conditions. The role of autophagy in cardiovascular diseases especially in the regulation of angio-genesis is discussed in this paper. Besides, the paper also in-cludes the discussion about the mechanisms of autophagy in the regulation angiogenesis, which may provide references for follow-up research and clinical treatment.

Cardiovascular disease is a serious threat to human health and quality of life ,and it has become the leading cause of death in human.Thus,looking for effective drugs to reduce the mortality and morbidity of such a disease has become a problem to be solved.Due to its good efficacy of activating blood circula-tion and dissipating blood stasis,salvia miltiorrhiza has been widely used in the treatment of cardiovascular disease and ob-tained a good curative effect.Salvianolic acid B is one of the main water-soluble components of salvia miltiorrhiza extract and studies have shown that salvianolic acid B possesses many biolog-ical activities,which not only has a good protective effect on my-ocardial infarction,but could significantly alleviate myocardial ischemia-reperfusion injury.This article reviews the research progress of salvianolic acid B in cardiovascular diseases,and al-so includes discussion about the mechanisms of salvianolic acid B in the regulation of cardiovascular diseases,which may provide references for follow-up research and clinical treatment.

OBJECTIVE: To discuss the quality of reporting in randomized controlled trials (RCTs) of Chinese herbal medicine (CHM), and to provide suggestions for improving the reporting of future clinical studies in this therapeutic area. METHODS: A search of the Cochrane Library was conducted to identify RCTs of CHM. A revised CONSORT checklist designed for CHM clinical studies was implemented. The revised CONSORT checklist contained 63 items, including the following new items added specifically for CHM: (1) "syndrome of disease" based on Chinese medicine theories; (2) rationale of CHM formula; (3) formula composition; (4) preparation form of CHM; (5) quality control of CHM. RESULTS: The overall reporting quality of the RCTs as assessed with the revised CONSORT checklist varied between 19% and 44%, with a median score of 32% (standard deviation 8%). CONCLUSION: The overall quality of reporting of RCTs of CHM evaluated with a revised CONSORT checklist was poor, reflecting the need for improvements in reporting future clinical trials in this area. RECOMMENDATIONS: To improve the quality of reporting of RCTs of CHM, we recommend adopting a revised CONSORT checklist that includes items specific to CHM. We also recommend that editors of CHM journals require authors to use a structured approach to presenting their trials as a condition of publication.

AIM To explore the effects of Sangtong alkaloids (total alkaloids and total flavones from Mori folium,STA) on the random blood glucose,starch tolerance and hepatic insulin resistance in db/db mice with type 2 diabetes mellitus.METHODS Eight-week-old db/db mice were divided into model group (normal saline),acarbose group (39 mg/kg) and Sangtong alkaloids groups (105,210 and 420 mg/kg),db/m mice were used as control group (normal saline).The mice were given by intragastric administration for one hundred days.The random blood glucose of mice was determined every ten days.The starch tolerance was determined in the 100th day,together with the determination of serum insulin level,insulin resistance index and insulin sensitivity index.Histopathology changes of pancreas were observed by HE staining.Protein expressions of P-IRS1,P-PI3 K,P-AKT and GLUT2 were detected by Western blot.RESULTS Sangtong alkaloids significantly decreased the random blood glucose,serum insulin level and insulin resistance index,and increased the insulin sensitivity index in db/db mice.Meanwhile,Sangtong alkaloids ameliorated the pancreas histopathological damage and up-regulated the protein expressions of P-IRS1,P-PI3K,P-AKT and GLUT2 in liver.CONCLUSION Sangtong alkaloids can decrease the random blood glucose and improve the insulin resistance of liver in db/db mice with type 2 diabetes mellitus,whose mechanism may be associated with the regulation of hepatic insulin signal pathway.
