Objective To investigate the effects of Schisandrae Sphenantherae Fructus and processed with vinegar on lipid metabolism of rats with type 2 diabetes mellitus (T2DM). Methods The rat model of T2DM was induced by high fat diet plus STZ. The rats were randomly divided into blank group, model group, Schisandrae Sphenantherae Fructus high-dose group and low-dose group, and vinegar Schisandrae Sphenantherae Fructus high-dose group and low- dose group. The rats in each group were fed with the corresponding medicine for gavage for 30 d. FINS, FFA, TC, TG, HDL-C, LDL-C, and MDH, total protein content of liver tissue were detected. HE staining was used to observe the histomorphological changes of liver and pancreas in rats. Results Compared with the model group, Schisandrae Sphenantherae Fructus groups and vinegar Schisandrae Sphenantherae Fructus groups did not show obvious effects on improving FBG and FINS, but it could raise varying degrees of HDL-C and MDH, and reduce FFA, LDL-C, TC, and TG, among which vinegar Schisandrae Sphenantherae Fructus could significantly regulate metabolism in T2DM rats. Conclusion Vinegar Schisandrae Sphenantherae Fructus can enhance the lipid metabolism regulatory function of T2DM rats.

Objective:To explore the influence of Shenhong Tongluo Granules in the lipid levels,atherosclerosis plaques and apoptosis in the plaques of atherosclerotic apolipoprotein E (ApoE)-knokout mice,and to clarify the mechanism of Shenhong Tongluo Granules in anti-atherosclerosis.Methods:Forty SPF male mice aged six-week old were randomly divided into normal control group,model group,low dose of traditional chinese medicine (TCM) group and high dose of TCM group (n=10)after fed adaptively for 1 week.The mice in normal control group were fed with normal diet continuously, the mice in other three groups were fed with high fat diet to establish atherosclerosis model,and then the mice in low and high doses of TCM groups were respectively given Shenhong Tongluo Granules (5.06 and 10.12 g·kg-1 · d-1 )by gavage for 6 weeks. The levels of serum total cholesterol (TC),triglycerides (TG),low density lipoprotein cholesterol (LDL-C)and high density lipoprotein cholesterol (HDL-C)of the mice in various groups were measured after the eyeball blood was collected.The aortic arch tissue was separated,and the morphotogy and the areas of atherosclerotic plaques were observed and calculated by HE staining;the apoptosis in plaques of the mice was evaluated by TUNEL method, and the apoptosis index was calculated. The expressions of apoptosis-assoicated gene Bcl-2 and Bax protein were measured by immunohistochemical staining.Results:The serum level of TG in low dose of TCM group was lower than that in model group (P <0.05);the serum levels of HDL-C in low and high doses of TCM groups were lower than that in model group (P <0.05 or P <0.01);the serum levels of TG and HDL-C in high dose of TCM group was higher than that in low dose of TCM group (P <0.05).The areas of atherosclerotic plaques of the mice in low and high doses of TCM groups were significantly smaller than that in model group (P <0.01).The apoptosis index of mice in low and high doses of TCM groups were significantly lower than that in model group (P <0.01);the expression levels of Bcl-2 protein in atherosclerosis plaques of the mice in low and high doses of TCM groups were lower than that in model group,while the expression levels of Bax were significantly higher than that in model group (P <0.05 or P <0.01).Conclusion:Shenhong Tongluo Granules could effectively reduce the serum lipid level of ApoE-/-mice,meanwhile it could inhibit apoptosis by regulating the expressions of Bcl-2 and Bax protein,and then inhibit the progression of atherosclerotic plaques.

Objective:To explore the influence of rosuvastatin in the lipid levels, atherosclerosis plaque and apoptosis in the plaque of atherosclerotic apolipoprotein E (ApoE)-knockout mouse models, and to clarify the mechanism of rosuvastatin in inhibiting atheromatous plaque and apoptosis in the plaque.Methods:Thirty healthy six-week old male mice were randomly divided into high fat diet group (n=10),rosuvastatin group (n=10)and general diet control group (n=10).The mice in first two groups were fed with high fat diet,and the mice in general diet control group were fed with general diet;4 weeks later the mice in three groups were respectively given 0.9% NaCl solution,rosuvastatin (10 mg·kg·d-1 )and 0.9% NaCl solution by gavage for 8 weeks.And then ELISA was used to detect the serum lipid levels,the area of atherosclerotic plaque was measured by HE staining, and the apoptosis in plaques was detected by TUNEL method;the expression of apoptosis-assoicated gene Bax protein was measured by immunohistochemical staining.Results:Compared with high fat diet group,the levels of total cholesterol (TC)and low density lipoprotein cholesterol (LDL-C)of the mice in rosuvastatin group were significantly decreased (P<0.05 or P<0.01),and the 1evel of high density lipoprotein cholesterol (HDL-C)was significantly increased (P<0.01).The aortic atherosclerotic plaque of the mice in high fat diet group was massive with a great quantity of foam cells, cholesterol crystal, necrotic cells and inflammatory cells in the plaque;the aortic atherosclerotic plaque of the mice in rosuvastatin group was smaller with less foam cells,necrotic cells and inflammatory cells;the aortic atherosclerotic plaque area of the mice in rosuvastatin group was significantly smaller than that in high fat diet group (P<0.01);the apoptotic index in the aortic atherosclerotic plaque of the mice in rosuvastatin group was significantly lower than that in high fat diet group (P<0.01).Compared with high fat diet group,the expression of Bax protein in rosuvastatin group was significantly decreased.Conclusion:Rosuvastatin may inhibit the progression of atherosclerotic plaque and the apoptosis in plaques through mitochondrial pathway.

Objective To investigate the heterogeneity of the left ventricular reference value in echocardiography mesurements by Meta analysis. Methods A literature retrieval in PubMed,Embase, Medline and other databases from January 2005 to September 2017 related to left ventricular normal reference value in healthy adults was performed. Cohrane′s Q test was used to test the heterogeneity,and I2 was used as a statistic for the description of heterogeneity. Subgroup analysis,sensitivity analysis and Meta regression were used to analyze the sources of heterogeneity. Results The Meta analysis enrolled 9 studies including 5 933 normal cases. The heterogeneity test showed that the left ventricular normal reference value of echocardiography was highly heterogeneous among the studies. In subgroup analysis, some measurements′ heterogeneity were significantly reduced. Meta regression analysis showed that the contribution of racial specificity to heterogeneity was relatively high in some measurements. Conclusions The heterogeneity of left ventricle is mainly related to racial specificity,but it cannot fully explain the heterogeneity between studies. Further studies are needed to demonstrate the involved factors of heterogeneity of left ventricular normal reference values.
