To study the effects of Guanxinping Tablet (GT) containing serum on H2O2-induced apoptosis and the nuclear factor kappa B (NF-kappaB) expression in vascular endothelial cells (VECs). Rabbits were randomly divided into the normal control group (treated with normal saline, 10 mL/kg), the verapamil group (0. 02 g/kg, 10 mL/kg), the small dose GT group (2; 8 g/kg, 10 mL/kg), the middle dose GT group (5.6 g/kg, 10 mL/kg), and the large dose GT group (11.2 g/kg, 10 mL/kg), 3 in each group. The medication was given to rabbits by gastrogavage for 3 successive days. The gastrogavage was performed twice on the last day with an interval of 2 h. One h after the last medication the peripheral blood was sampled from the vein of the ear edge. The blood was put for 1 h and centrifuged at 2 500 r/min for 30 min. The serum was extracted and deactivated at 56 degrees C for 30 min to prepare the drug containing serum. The apoptosis injury model was established using 100 micromol/L H2O2 induced VECs in the log phase growth. After modeling they were divided into 6 groups, 5 samples in each group, i. e., the normal group (10% vehicle serum culture solution), the model group (10% vehicle serum culture solution +100 micromol/L H2O2), the verapamil group (10% verapamil serum culture solution +100 micromol/L H2O2), the low dose GT group (10% low dose GT culture solution +100 micromol/L H2O2), the middle dose GT group (10% middle dose GT culture solution + 100 micromol/L H2O2), and the high dose GT group (10% high dose GT culture solution + 100 micromol/L H2O2). THE VEC apoptotic rate was detected using flow cytometry. The protein expression of NF-kappaB was detected using Western blot. The VEC apoptosis rate (9.00% +/- 1.18%) and the protein expression of NF-kappaB (0.39% +/- 0.06%) increased more in the model group than in the normal control group (P<0.01). Compared with the model group, the VEC apoptosis rate of the verapamil group (6.00% +/- 0.18%), the large dose GT group (5.30% +/- 0.08%), and the middle dose GT group (6.83% +/- 0.51%) were obviously lower. The expression of NF-kappaB of each treatment group significantly decreased (the verapamil group: 0.28% +/- 0.03%; the small dose GT group: 0.33% +/- 0.03%; the middle dose GT group: 0.30% +/- 0.03%; the large dose GT group: 0.28% +/- 0.04%, P<0.01, P<0.05). GT could fight against H2O2-induced VEC cell apoptosis. Its mechanism might be correlated with regulating the expression of NF-kappaB protein.

Clinical and Experimental Hypertension | Year: 2014
Background: Chemerin is a new adipokine elevated in states of obesity and metabolic syndrome. In order to identify the role of chemerin in hypertension, we conducted a case - control study to evaluate the role of chemerin in hypertension. Methods: Two hundred and thirty-seven new-diagnosed essential hypertensive (EH) patients and one hundred and ten normotensive healthy subjects (NT) were enrolled. After an overnight fasting, participants underwent an oral glucose-tolerance test (OGTT). Anthropometric measurements and serum analyses were checked, including body mass index (BMI), waist circumference, insulin, triglycerides, total cholesterol, HDL-cholesterol, LDL-cholesterol, glucose, chemerin, hs-CRP, TNF-α and IL-6. Results: Compared with healthy controls, subjects with hypertension had significantly higher chemerin serum levels (p<0.001). In hypertensive patients, chemerin level was significantly associated with metabolic characteristics including BMI, systolic blood pressure, fasting glucose and insulin, OGTT 2-hour glucose, plasma triglycerides, plasma total cholesterol, HOMA-IR and markers of inflammation including hs-CRP, TNF-α and IL-6, independent of age and gender. Only gender, HOMA-IR, TNF-α and TG were independently related factors to plasma chemerin level after multiple regression analysis. In logistic regression analysis, high chemerin level was an independent predictor of the presence of hypertension (OR: 1.045, p<0.001) when metabolic variables were adjusted for. However, the association was lost when further adjustment for inflammatory markers including hs-CRP, TNF-α and IL-6 (OR: 1.022, p=0.289). Conclusions: Chemerin is strongly associated with markers of inflammation and components of the metabolic syndrome in hypertensive subjects and was independently associated with hypertension after adjustment for age, gender and metabolic risk factors. © 2014 Informa Healthcare USA, Inc.

Chinese Traditional and Herbal Drugs | Year: 2013
The development of Chinese materia medica (CMM) formula granule is a great reform on CMM. Compared with the traditional herbal pieces, CMM formula granule is not only convenient and rapid-acting as boiling-free, but also advanced in producing techniques, and easily handled in both storage and quality-control. It could perfectly meet the basic reqirement on modern drugs and have a broad market prospect both at home and abroad. The popularization and application of CMM formula granule could be a new way to promote the internalization of CMM. Through the analysis of the pushing effects, international competitive advantages, and problems on accessing to the international market, this essay tries to put forward some effective countermeasures for CMM formula granule with expecting to provide a new idea and a new route for the internationalization of CMM.

To study the correlation between Apo E gene polymorphism and patients with coronary heart disease (CHD) of phlegm-stasis syndrome (PSS). 78 CHD patients were assigned to PSS (49 cases) and non-phlegm-stasis syndrome (NPSS). Polymorphisms of Apo E gene in 78 CHD patients and 100 healthy subjects were detected by complete DNA sequencing. Five gene types as E3/3, E4/4, E2/ 3, E2/4, and E3/4 were detected in the two groups. The frequencies of genotype E3/3 and epsilon 3 allele were significantly lower in CHD patients than in the healthy subjects (P<0.01). But the frequencies of genotype E3/4 and epsilon 4 allele were significantly higher in CHD patients than in the healthy subjects (P<0.01). In CHD patients, the frequencies of genotype E2/4 + E3/4 + E4/4 and epsilon 4 allele were higher in PSS than in NPSS. Apo E epsilon 4 allele was a susceptible allele to CHD, which was closely correlated to CHD PSS. It was inferred that it might be one of main susceptible alleles for CHD PSS.

To study the effects of ApoE gene polymorphism on anti-inflammatory action of Xuezhikang Capsule. One hundred and two patients with hyperlipidemia (as the treated group) and one hundred healthy volunteers (as the control group) were enrolled in the case-control study. Total DNA of the peripheral blood was extracted and ApoE genotypes were determined by PCR sequence analysis. The serum levels of tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), and high sensitivity C reactive protein (hs-CRP)were measured in all subjects. The changes of TNF-alpha, IL-6, and hs-CRP were detected before and after 6-week Xuezhikang Capsule treatment, thus analyzing the correlation between ApoE gene polymorphism and changes of each inflammatory factor. The frequency of E3/3 genotype was 86% (86/100 cases)in the control group, significantly higher than that of the treated group (62.7%, 64/102 cases). The frequency of E3/4 genotype was 6% (6/100 cases) in the control group, significantly lower than that of the treated group (21.6%, 22/102 cases; both P < 0.05). Compared with the control group, the serum levels of TNF-alpha, IL-6, and hs-CPR were higher in the treated group before treatment (P < 0.05). In hyperlipidemia patients with E3/4 + E4/4 genotype, the serum level of TNF-alpha was higher than that of E3/3 genotype (P < 0.05); the serum level of IL-6 was higher than that of E2/E2 + E2/E3 genotype (P < 0.05); the serum level of hs-CRP was higher than that of E2/E2 + E2/E3 and E3/E3 genotype (P < 0.05). But there was no statistical difference in the serum levels of TNF-alpha, IL-6, or hs-CPR between E3/3 and E2/E2 + E2/E3 genotype. After 6-week intervention of Xuezhikang Capsule, the serum levels of TNF-alpha, IL-6, and hs-CRP were lower in the treated group (P < 0.05), but the serum levels of TNF-alpha and IL-6 were still higher than those of the control group (P < 0.05). But there was no statistical difference in the decrement of TNF-alpha, IL-6, or hsCRP among E2/E2 + E2/E3, E3/E3, or E3/4 + E4/4 genotypes (P > 0.05). The distribution of ApoE gene polymorphism is different between the hyperlipidemia patients and the healthy people. Chronic inflammatory reactions exist in hyperlipidemia patients, especially in those with e4 allele. Xuezhikang Capsule showed anti-inflammatory effects, but ApoE gene polymorphism did not affect its effects.
