Xuefu Zhuyu decoction (XFZYD) is a famous traditional Chinese medicine (TCM) formula, is widely used in the treatment of cardiovascular and cerebrovascular diseases in China over one hundred years. But its effect on antioxidant and drug-metabolizing enzymes are unknown. This study was to observe the effects of Xuefu Zhuyu decoction (XFZYD) on the activities of antioxidant and drug metabolism enzymes (DMEs) in liver of rats. Male SD rats, treated with XFZYD at the dosage of 3.51, 7.02 and 14.04 g x kg(-1) per day for 15 days, serum were collected, tissue fluid, cytosols and microsomes isolated from liver tissues were prepared by centrifugation according to the standard procedure, the activities of antioxidant enzymes and drug-Metabolizing Enzymes were determined by UV-V is spectrophotometer. In serum, the activities of AST was not significantly affected by the treatment with XFZYD, at the high- est dose, the levels of ALT, Cr and BUN were significantly decreased (P < 0.05). GPX were significantly increased at the dose of 7.02, 14.04 g x kg(-1) (P < 0.05), CAT were significantly increased at the highest dose (P < 0.05). T-SOD was not significantly af- fected by this treatment. In the liver tissue, GPX was significantly increased at the dose of 3.51, 7.02 g x kg(-1) (P < 0.05), GST, CAT and T-SOD were not significantly affected following this treatment. In cytosols, GST was significantly increased at the dose of 3.51 g x kg(-1) (P < 0.05), T-SOD was remarkable induced at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05). In microsomes, XFZYD had no significant effect on Cytochromeb5, NADPH-Cytochrome P450 reductase, CYP3A, CYP2E1 and UGT, XFZYD significantly in- duced GST at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05), and the level of GSH were significantly increased by XFZYD at the dose of 3.51, 7.02 and 14.04 g kg(-1) (P < 0.05). These findings suggest XFZYD can induce the activities of GPX, CAT, SOD, GST and increase GSH level in liver of rats, which indicate XFZYD may have detoxification and antioxidant functions.

OBJECTIVETo study the treatment effect of Wenxin Keli on isoproterenol (ISO) induced heart failure in rats.

METHODSixty six-week old male Wistar rats were randomized into six groups. The rats in control group were only receive distilled water every day. The rats in ISO group also received two subcutaneous injections (85 mg x kg(-1)) of ISO, which were separated by a 24 hour interval and began to receive distilled water 2 weeks later every day. The rats in Wenxin Keli and control group were receive Wenxin Keli (9 mg x kg(-1)) every day. The rats in Wenxin Keli and ISO group received two subcutaneous injections (85 mg x kg(-1)) of ISO, which were separated by a 24 hour interval and began to receive Wenxin Keli (9 mg x kg(-1)) 2 weeks later every day. The rats in valsartan and control group were receive valsartan every day. The rats in valsartan and ISO group received two subcutaneous injections (85 mg x kg(-1)) of ISO, which were separated by a 24 hour interval and began to receive valsartan 30 mg x kg(-1) 2 weeks later every day. Echocardiogram measurement in rats were carried out after 4 weeks and 10 weeks feeding medince of hemodynamic measurement and aconitine induced arrhythmia in rats were carried out after 10 weeks.

RESULTEchocardiogram indicated that left ventricular internal diameter at diastolic phase (LVIDd), left ventricular internal diameter at systolic phase (LVIDs), LV percent fractional shortening (FS) and LV ejection fraction (EF) were decreased in the ISO group. Treatment with valsartan 4 weeks later, FS and EF were increased compared with the ISO group and 10 weeks later, LVIDd, LVIDs, FS, EF were increased. However, treatment with Wenxin Keli 10 weeks later, LVIDs, FS, EF were not changed obviously. Hemodynamic measurement showed that left ventricular end diastolic pressure (LVEDP), left ventricular systolic pressure (LVSP), and dp/dt(max) were improved after 10 weeks of treatment with valsartan. The LVEDP was decreased and dp/dt(max), was increased after 10 weeks of treatment with Wenxin Keli. Aconitine induced arrhythmia in rats in Wenxin Keli and control group were less serious than those in control group, aconitine induced arrhythmia in rats in Wenxin Keli and ISO group were less serious than those in ISO group.

CONCLUSIONWenxin Keli could greatly improve the ISO induced cardiac dysfunction and protect the aconitine-induced arrhythmia in rats.

BACKGROUND:The formation of atherosclerotic lesions in apolipoprotein E knockout mice is similar to that of human systemic atherosclerosis, and apolipoprotein E knockout mice are ideal animals for current establishment of atherosclerosis models.
OBJECTIVE:To research the pathological process of atherosclerosis in apolipoprotein E knockout mice aged different weeks, and to explore the effect of different diets on the occurrence and development of atherosclerosis in apolipoprotein E knockout mice.
METHODS:Male apolipoprotein E knockout mice aged 8 weeks old were randomly divided into two groups, and fed with high fat diet and normal diet, respectively, for 8, 12, 16, 20, and 24 weeks.
RESULTS AND CONCLUSION:Serological detection revealed that serum total cholesterol, triglycerides and low density lipoprotein levels were significantly higher in different weeks of mice of high fat diet group than in the normal diet group (P<0.05), in a time-dependent manner. Gross and frozen oil red O staining showed that atherosclerotic plaque area of lumen was significantly larger in the high fat diet group than in the normal diet group (P<0.05), in a time-dependent manner. At this time, significant differences in plaque area of lumen at each week were detected between both groups (P<0.05). Apparent lipid plaque was visible in aorta at 16 weeks of high fat diet in mice. Results demonstrated that apolipoprotein E knockout mice of atherosclerosis were successful y established. The formation of lipid streaks and fiber hyperplasia was faster in high fat diet group than in the normal diet group.

OBJECTIVETo investigate the relationship between polymorphisms of genes (CYP17, CYP19 and SULT1A1) involved in estrogen metabolism and susceptibility to breast cancer in Chinese women.

METHODSA case-control study was performed. PCR-base restriction fragment length polymorphism (PCR-RFLP) and short tandem repeat polymorphism (STRP) assays were used to detect the polymorphism distribution of CYP17, CYP19 and SULT1A1 in 213 breast cancer cases and 430 matched controls. Logistic regression analyses were used to determine the OR, multivariate adjusted OR and 95% CI of each and all three genes and estrogen exposure factors on the risk of breast cancer. Relationship between polymorphisms and clinic-pathological features was also assessed.

RESULTSThe frequency of A2 allele of CYP17 was 49.8% in cases and 49.1% in controls (P > 0.05). The frequency His allele of SULT1A1 in cases (13.6%) was significant higher than that of controls (9.5%) (P = 0.03). There was also significant difference in the frequencies of (TTTA)10 allele CYP19 which was 12.4% in cases and 8.2% in controls (P = 0.02). Multigenic model indicated that there was an increased risk of breast cancer with more numbers of high-risk genotypes in a dose-response effect (trend P = 0.05). Data from multivariate analysis showed that the allele of SULT1A1 His and CYP19 (TTTA)10 was positively associated with the risk of breast cancer. Other well-established risk factors as higher estrogen exposure including total years of menstrual, early menarche etc, and women with a higher BMI and WHR were all served as independent risks.

CONCLUSIONThis study indicated that the polymorphisms of estrogen-metabolizing genes were related to breast cancer.

OBJECTIVETo explore the influence of Astragalus membranaceus (AM) on serum cytokines, Th1, including interleukin-2 (IL-2) and gamma-interferon (gamma-IFN), and Th2, including interleukin-4 (IL-4) and interleukin-10 (IL-10), in patients with herpes simplex keratitis (HSK).

METHODSOne hundred and six HSK patients were randomly divided into the AM treated group and the ribavirin treated group. Levels of serum IL-2, IL-4, IL-10 and gamma-IFN of all the patients and 62 healthy person, selected from donors for control group, were determined by sandwich enzyme-linked immunosorbent assay (ELISA) technique.

RESULTSLevels of serum IL-4 and IL-10 in HSK patients were significantly higher and those of IL-2 and gamma-IFN were significantly lower than those in the healthy control (all P < 0.01). These parameters were significantly improved in the patients of the AM group after treatment, but with no change in patients of the ribavirin group.

CONCLUSIONAM can modulate the imbalance state of Th1/Th2 in HSK patients, improve their immune function disturbance, that shows important significance in treating HSK.
