OBJECTIVETo investigate the effect and explore the mechanism of Bushen Antai Recipe (BAR) on pregnancy rate and number of implantation site in blastocyst implantation dysfunction (BID) mice induced by indomethacin.
METHODSPregnant mice were divided into 3 groups randomly: the normal group, the model group and the BAR group. Tap water was given orally to the rats in the normal and model groups, and BAR to the rats in the BAR group from the first day of pregnancy for 5 or 8 days; on the 3rd and 4th day dissolvent was injected subcutaneously twice per day in the normal group, while indomethacin (4.33 mg/kg) was injected subcutaneously twice per day in the other two groups to establish implantation dysfunction model; serum estrogen (E) and progesterone (P4) levels were detected on the 5th and 8th day; the pregnancy rate and number of implanted site was observed and the receptors of E and P4 in endometrium of uterus were examined by immunohistochemistry on the 8th day.
RESULTSThe pregnancy rate and number of implanted site was 27.3% and 5.3 +/- 0.7 respectively in the model group, significantly lower than those in the normal group (90.9%, 13.3 +/- 2.8), and the BAR group (72.7%, 10.7 +/- 2.2, P < 0.05). Serum E level was higher in the BAR group than that in the model group on the 5th and 8th day, and even higher than that in the normal group on the 8th day; serum P4 level was lower in the model and BAR groups than that in the normal group on the 5th day (P < 0.01), but higher in the BAR group than that in the model group on the 8th day. Immunohistochemical observation showed that expressions of E and P4 receptor increased remarkably in the BAR group than those in the model group.
CONCLUSIONBAR increases the pregnancy rate and number of implanted site of indomethacrne induced BID mice through regulating E and P4 levels and enhancing the expressions of their receptors in the endometrium.

OBJECTIVETo observe and compare the protective effect of garlic oil against carbon tetrachloride (CCL)-induced acute liver injury.
METHODSThe experiments include 4 preventive groups and 2 therapeutic groups. In every preventive and therapeutic group, the mice were randomized into 6 groups with 15 each, including one negative control group, one solvent control group, one CCl4 model group and 3 garlic oil groups (25, 50, and 100 mg/kg body weight). Before given a single gavage of CCl4 (80 mg/kg), the mice were pretreated with garlic oil by gavage in preventive group 1 (30 days, once daily), preventive group 2 (5 days, once daily), preventive group 3 (ahead of 2 h, once), preventive group 4 (immediately, once) or the vehicle (corn oil, 10 ml/kg) in solvent control group. In therapeutic groups, the mice were gavaged garlic oil 2 h (once, in therapeutic 1) or for 5 days (once daily, in therapeutic 2) after administration CCl. After 24 h of the last administration, blood was collected and centrifuged at 2500 r/min at 4 degrees C for 10 min, and serum was removed to measure ALT and AST activities. The liver was dissected, weighed to calculate the liver coefficient (relative liver weight). At the same time, the liver samples were studied by histological examinations.
RESULTSCompared with negative group, the liver coefficient and the activities of ALT and AST in serum of model group were increased remarkably (P < 0.01). Compared with CCl model group, the liver coefficient and the activities of ALT and AST in serum were decreased significantly (P < 0.01) by garlic oil dose-dependently in each preventive group. Simultaneously, histological assessment showed that garlic oil effectively alleviated hepatocyte injuries induced by CCl4. Comparing the preventive effects of garlic oil in every group, it was better in preventive group 3 than others. However, all indexes and histological examinations in therapeutic group 1 did not show the difference with those of CCl4 model group. In therapeutic group 2, all indexes recovered after 5 d of CCl4 administration.
CONCLUSIONSGarlic oil can prevent acute liver injury induced by CCl4 and the effect is better in ahead of 2 h group than others.

OBJECTIVETo explore the role of cyclin dependent kinase 5 (CDK5) in 2, 5-hexanedione (HD)-induced neuropathy.
METHODSThirty male Wistar rats weighted 200 approximately 240 g were divided randomly into three groups, i.e. control group, 200 mg/kg HD group and 400 mg/kg HD group (n = 10 for each group). HD was administered to rats by intraperitoneal injection at dosage of 200 or 400 mg/kg for 8 weeks (five times per week) to establish the intoxicated rats model. The relative contents of CDK5, p35 and p25 were determined in cerebrum, spinal cord and sciatic nerve of rats by Western Blotting.
RESULTSCompared with that of the control group rats, p35 contents were significantly decreased (P < 0.01) in the cytosolic fractions of cerebrum and spinal cord in both the 200 and 400 mg/kg HD intoxicated rats, while in the membrane fractions of spinal cord and sciatic nerve, p35 contents were increased significantly (P < 0.01). The changes of p25 showed the same pattern with p35. P25 contents were significantly reduced (P < 0.05) in the cytosolic (cerebrum and spinal cord) and membrane (cerebrum) fractions of both HD-treated rats and were elevated (P < 0.01) in the membrane fraction of spinal cord and cytosolic fraction of sciatic nerve. The relative amounts of CDK5 were significantly decreased (P < 0.01) in the cytosolic and membrane fractions of cerebrum in both the 200 and 400 mg/kg HD intoxicated rats. Except for membrane fraction of sciatic nerve, the significant increased (P < 0.01) of CDK5 were observed in the spinal cord and sciatic nerve of both the 200 and 400 mg/kg HD treated rats.
CONCLUSIONHD can induce significant changes of CDK5 and its activators p35, p25 in nerve tissues, which may be related to the neuropathy induced by HD.

OBJECTIVETo study the role of CYP2E1 in the protective effects and mechanism of garlic oil (GO) on the peripheral nerve injuries induced by n-hexane.
METHODSFifty male Wistar rats were randomly divided into five groups (n = 10): the control, the GO (80 mg/kg) control, the n-hexane (2000 mg/kg) model, the low dose GO (40 mg/kg) plus n-hexane, and the high dose GO (80 mg/kg) plus n-hexane groups. All rats were treated by intragastric administration 6 times a week for 10 weeks. The gait scores were determined every two weeks for monitoring the peripheral neurotrosis. All rats were sacrificed in 10 weeks, the activities and expression levels of hepatic CYP2E1 and 2, 5-HD in serum were examined.
RESULTSAs compared with control group, the content and activity of hepatic CYP2E1 in GO control group reduced by 83.1% and 48.3% respectively (P < 0.01), the content and activity of hepatic CYP2E1 in model group increased by 112.5% and 72.2% respectively (P < 0.01). As compared with model group, the contents of hepatic CYP2E1 in low dose and high dose GO groups reduced by 32.9% and 39.1% respectively, the activities of hepatic CYP2E1 in low dose and high dose GO groups reduced by 27.4% and 44.5% respectively (P < 0.01); the contents of serum 2,5-HD in low dose and high dose GO groups reduced by 47.7% and 78.7% respectively (P < 0.01). The gait scores in model, low dose and high dose GO groups were significantly lower than that in control group, but the gait scores in low dose and high dose GO groups were significantly lower than that in model group (P < 0.05).
CONCLUSIONGarlic oil can effectively reduce the peripheral neurotrosis induced by n-hexane due to the decreased content and activity of hepatic CYP2E1, resulting in the reduced formation of 2, 5-HD from n-hexane.

OBJECTIVETo study the protective effects of garlic oil (GO) on the peripheral nerve injuries induced by n-hexane.
METHODSMale Wistar rats were randomly divided into four groups (10 rats in each group): the control, the n-hexane treatment (2000 mg/kg), the low dose GO, and the high dose GO groups. The rats in the low and high doses of GO groups were pretreated with GO (40 and 80 mg/kg) before exposure to n-hexane (2000 mg/ kg), while the animals of the n-hexane treatment group were given normal saline and then 2000 mg/ kg n-hexane. The rats were exposed to GO and n-hexane 6 times a week for 10 weeks. The gait scores and staying time on the rotating rod for all rats were detected every two weeks. The rats were sacrificed at the end of ten weeks, then the levels of alcohol dehydrogenase (ADH), maleic dialdehyde (MDA), reduced glutathione (GSH), glutathione peroxidase(GSH-Px), total antioxidation capacity(T-AOC) and the ability of inhibition of *OH in livers were examined.
RESULTSThe gait scores increased significantly and the time staying on the rotating rod obviously decreased in rats of n-hexane treatment group, as compared with control group (P < 0.05 or P < 0.01). In the hepatic tissues of n-hexane group, the levels of MDA and ADH significantly increased, the activities of GSH-Px, T-AOC and the ability of inhibition of *OH obviously decreased, as compared to control group (P < 0.05 or P < 0.01). In 2 GO groups, the gait scores and the staying time on the rotating rod were significantly improved, the levels of MDA and ADH significantly decreased, the activities of GSH-Px, T-AOC and the ability of inhibition of *OH obviously increased, as compared with n-hexane group (P < 0.05 or P < 0.01 ).
CONCLUSIONADH could play an important role in the protective effects induced by garlic oil on the peripheral nerve injuries produced by n-hexane.

OBJECTIVETo explore the influence of smoking on chronic diseases among people with various income levels in China.
METHODSCross-sectional study on smoking behavior, chronic disease and income level was performed using database of the Second National Health Service Study (1998) provided by the Ministry of Health in China.
RESULTSCompared to never-smokers, smokers (including current smokers and former smokers) had a higher rate of having chronic diseases, after adjusted in age, income, educational level, employment status and type of jobs with corresponding countryside (OR = 1.185, 95% CI: 1.121 - 1.253 and town OR = 1.083, 95% CI: 1.010 - 1.161). Smoking had a more serious effect on having chronic illness in males from the countryside (former-smoker OR = 2.764, 95% CI: 2.471 - 3.092) than in town (former-smoker OR = 2.112, 95% CI: 1.844 - 2.419). Smokers at the lowest income level had a higher possibility of having chronic illness (town OR = 2.076, 95% CI: 1.551 - 2.780; countryside OR = 2.903, 95% CI: 2.248 - 3.749) than those at the highest income level (town OR = 1.785, 95% CI: 1.285 - 2.479 in the countryside OR = 2.466, 95% CI: 1.941 - 3.134).
CONCLUSIONSmoking might cause more serious health problems to people at lower income level in China.

BACKGROUND: Few studies investigated serum uric acid levels in patients with acute ST-elevation myocardial infarction (STEMI). The study was to assess the clinical value of serum uric acid levels in patients with acute ST-elevation myocardial infarction (STEMI). METHODS: Totally 502 consecutive patients with STEMI were retrospectively studied from January 2005 to December 2010. The level of serum lipid, echocardiographic data and in-hospital major adverse cardiovascular events (MACE) in patients with hyperuricemia (n=119) were compared with those in patients without hyperuricemia (n=383). The relationship between the level of serum uric acid and the degree of diseased coronary artery was analyzed. All data were analyzed with SPSS version 17.0 software for Student's t test, the Chi-square test and Pearson's correlation coefficient analysis. RESULTS: Serum uric acid level was positively correlated with serum triglyceride level. Hyperlipidemia was more common in hyperuricemia patients than in non-hyperuricemia patients (43.7% vs. 33.7%, P=0.047), and serum triglyceride level was significantly higher in hyperuricemia patients (2.11±1.24 vs. 1.78±1.38, P=0.014). But no significant association was observed between serum uric acid level and one or more diseased vessels (P>0.05). Left ventricular end-diastolic diameter (LVEDd) was larger in hyperuricemia patients than in non-hyperuricemia patients (53.52±6.19 vs. 52.18±4.89, P=0.041). The higher rate of left systolic dysfunction and diastolic dysfunction was discovered in hyperuricemia patients (36.4% vs. 15.1%, P<0.001; 68.2% vs. 55.8%, P=0.023). Also, hyperuricemia patients were more likely to have in-hospital MACE (P<0.05). CONCLUSIONS: Serum uric acid level is positively correlated with serum triglyceride level, but not with the severity of coronary artery disease. Hyperuricemia patients with STEMI tend to have a higher rate of left systolic dysfunction and diastolic dysfunction and more likely to have more in-hospital MACE.
