Objective To determine the current prevalence and risk factors of metabolic syndrome (MS) among adult residents in Chinese developed areas.Methods The clinical data of 6614 adult residents,including 4051 women,from Guangdong and Jiangsu provinces from China Diabetes and Metabolic Disorders Study (2007-2008) were analyzed.Age and sex standardized prevalences of MS were calculated according to the criteria of Chinese Diabetes Society (CDS),US National Cholesterol Education Program Adult Treatment Panel Ⅲ (ATP Ⅲ),International Diabetes Federation (IDF) and Joint Interim Statement (JIS),respectively.Logistic regression analysis was performed to identify the risk factors of MS.Results Age and sex standardized prevalences of MS were 17.88％ (CDS),28.50％ (ATP Ⅲ),21.99％ (IDF) and 31.50％ (JIS),respectively.The prevalences of residents with at least one metabolic abnormality were 67.86％ (CDS) 79.56％ (ATP Ⅲ),79.62％ (IDF) and 80.74％ (JIS),respectively.MS was more common in female than in male by the ATPⅢ and IDF criterion (ATPⅢ:30.63％ vs 26.45％,P ＜0.01 ; IDF:26.04％ vs 17.91％,P ＜ 0.01),while the prevalence was higher in male by CDS criteria (15.94％ vs 19.87％,P ＜0.01).There was no significant difference in the MS prevalence between the rural and the urban residents.Kappa test showed ATP Ⅲ and JIS criteria were most homogenous (κ =0.95,P ＜ 0.01).The risk factors for MS by the logistic regression model were male,older age,lower degree of education,family history of hypertension and obesity,drinker as well as uncontrolled diet.Conclusion The prevalence of MS is high in the adult residents of Chinese developed areas (Guangdong and Jiangsu provinces),whatever diagnostic criterion was used.Effective measures should be taken to control the modifiable MS risk factors.

OBJECTIVETo discuss the changes in Wnt pathway inhibiting factors in esophageal precancerosis lesions induced by methyl benzyl nitrosamine (MBNA) and the effect of Gexia Zhuyu decoction.

METHODWistar rats were subcutaneously injected with MBNA (3.5 mg x kg(-1) for twice per week to establish the model. Since the 1st day after the model establishment, they were orally administered with Gexia Zhuyu decoction (16, 8 mg x kg(-1)). At the 10th week, esophageal tissues were collected to observe the pathological changes of esophageal mucosa, detect SFRP1, sFRP4, Axin1, Axin2 and GSK-3β mRNA levels.by fluorescent quantitation PCR analysis and β-catenin protein level by Western blotting.

RESULTBeing induced by MBNA, rats in the model group showed slight atypical hyperplasia in the histopathological examination. Compared with the normal group, Gexia Zhuyu decoction dose high and low groups showed no significant pathomorphological and histological changes. The model group showed lower gene transcription levels of esophageal tissues sFRP1, sFRP4, Axin1 and Axin2 (P < 0.05 or P < 0.01) and higher β-catenin protein expression level (P < 0.01) than the normal control group. The Gexia Zhuyu decoction low dose group showed higher gene transcription levels of esophageal tissues sFRP1, sFRP4, Axin1 and Axin2 (P < 0.05 or P < 0.01) and lower β-catenin protein expression level (P < 0.01) than the normal control group.

CONCLUSIONUp-regulated β-catenin protein level and down-regulated Wnt pathway could enhance Wnt pathway activity of MBNA-induced esophageal precancerous lesions. Gexia Zhuyu decoction could down-regulate the β-catenin protein level and up-regulate the transcription level of Wnt pathway inhibiting factors, but could not block MBNA-induced esophageal precancerosis lesions.

OBJECTIVETo explore the effect of puerarin in improving the insulin resistance (IR) and its closely related abnormal lipid and fibrinolytic activity in patients with coronary heart disease (CHD).

METHODSSeventy-six patients with CHD were randomly divided into two groups, 40 in the puerarin group and 36 in the routine treated group. Puerarin 500 mg was given to the former in addition to routine therapy by adding to 250 ml of normal saline for intravenous dripping once a day with a therapeutic course of 3 weeks. The changes of fasting blood glucose (FBG), fasting plasma insulin (FINS), plasma total cholesterol (TC), triglyceride (TG), low and high density lipoprotein cholesterol (LDL-C & HDL-C) and plasminogen activator inhibitor-1 (PAI-1) activity were measured before and after treatment, and the insulin sensitivity index (ISI) calculated. At the same time, tissue plasminogen activator (tPA) activity before and during venous occlusion test (VOT) was tested. Besides, 30 healthy subjects were taken as control.

RESULTSIn CHD patients, FINS, TC, TG, LDL-C and PAI-1 levels were higher and ISI, HDL-C and tPA before and during VOT were lower than those in the healthy controls. FINS and ISI correlated well with lipids and fibrinolytic abnormality. After puerarin treatment, FINS level lowered and ISI increased significantly (P < 0.01), while comparing with the routine group, TC, TG, LDL-C and PAI-1 were lower but HDL-C and tPA activity before and during VOT were higher in the puerarin group (P < 0.05, P < 0.01). Correlation analysis showed that FINS was positively correlated with TC, TG, LDL-C and PAI-1 and negatively correlated with HDL-C, tPA before and during VOT; ISI was negatively correlated with TC, TG, LDL-C and PAI-1 and positively correlated with HDL-C and tPA before and during VOT in the puerarin group.

CONCLUSIONPuerarin could improve the IR, IR related lipid and fibrinolytic activity abnormality in CHD patients.

OBJECTIVEChinese herbal medicine has been extensively used in the treatment of vascular dementia (VaD), but lacked systematic review on its efficacy and safety. So we conducted a systematic review to assess the efficacy and safety of Chinese herbal medicine in treating VaD.

METHODSCNKI, CBM, PubMed, and Wiley Online Library were retrieved for randomized trials (RCTs) on Chinese herbal medicine treating VaD patients. Randomized parallel control trials by taking Chinese herbal medicine as one treatment method and placebos/cholinesterase inhibitors/Memantine hydrochloride as the control were included. Quality rating and data extraction were performed. RevMan5.2.0 Software was used for meta-analysis. Standardized mean difference (SMD) at 95% confidence interval (CI) was used to indicate effect indicators of results.

RESULTSSeven RCTs met the inclusive criteria. Totally 677 VaD patients were randomly assigned to the treatment group and the control group. Descriptive analyses were performed in inclusive trials. The cognitive function was assessed in all trials. Results showed Mini-Mental state examination (MMSE) score was better in the Chinese herbal medicine group than in the placebo group, but with no significant difference when compared with the donepezil group (P > 0.05). Adverse reactions were mainly manifested as gastrointestinal symptoms such as abdominal pain in the Chinese herbal medicine group. But they occurred more in the donepezil group than in the Chinese herbal medicine group.

CONCLUSIONSThe methodological quality of included trials was poor with less samples. Results of different trials were lack of consistency. Present evidence is not sufficient to prove or disapprove the role of Chinese herbal medicine in improving clinical symptoms and outcome indicators of VaD patients. Their clinical efficacy and safety need to be supported by more higher quality RCTs.
