Objective To explore the anomalous effects of India buead and coix seed powder on phlegm-dampness constitution dyslipidemia through population-based intervention studies. Methods According to the experimental results of the model group with dyslipidemia, the phlegm-dampness population meeting the inclusion criteria were chosen as the samples for the randomized controlled trial, who were divided into test meal (21 males and 39 females) and blank control (23 males and 37 females) groups with 60 cases in each, aged 18 to 65 y and the total of 120 cases completed the study. Statistical analyses were performed with SPSS 18.0 statistical software. The self comparison wass conducted by the method of paired-sample t test and the comparison between groups was conducted by using independent sample t test. The categorical statistics were described as frequency and compared throughc2 test, P<0.05 was considered as statistically significant. Without changing the original way of life, the meal group having taken the India buead and coix seed powder was compared independently and with the control group for TC, TG, HDL-C and LDL-C to detect the trends and degrees of the level changes. Meanwhile, according to efficacy tests and standards, the changes in the level of TC, TG and HDL-C have been evaluated and the efficiency and total effective rates of all the variables have been calculated. Results After the intervention, there was a declining tendency in each variable, 8.9%in TC, 21.4%in TG, and 27.2%in LDL-C, except for an increase of 0.13 mmol/L in HDL. There were significant differences in the variables before and after the intervention (P<0.05 in each). As for the test meal group after the intervention, the effectiveness of TC has been obtained in 25 cases and inefficacy in 35 cases, with efficiency of 41.7%;the effectiveness of TG has been shown in 53 cases and inefficacy in 7 cases, with efficiency of 88.3%;the effectiveness of HDL-C has been gained in26 cases and inefficacy in 34 cases, with efficiency of 43.3%; and the total effective rate was 57.8%. Conclusions There are significant changes and improvements in TC, TG, HDL-C and LDL-C in the test meal group after the intervention with the powder, which demonstrate that the powder is effective in the reduction of TG for animals with dyslipidemia and populations with phlegm-dampness constitution.

Objective To study the clinical effect of low molecular weight heparin on fetal growth restriction (FGR) prevention in early pregnancy.Methods 100 pregnant women had been employed in our study,they were divided into two groups,observation( n =60) and control( n =40) group.Both groups were given the natural vitamin E 0.1g,and folie acid 0.4mg daily oral administration,continuing to 12 weeks of gestation.5000 u of subcutaneous dalteparin sodium was added to pregnant women with notmal level of D-dimer in the observation group until 12 weeks of pregnancy,while the dose of Fragmin was adjusted in pregnant women with abnormal level of D-dimer until retuned to normal level.The pregnacy outcome of two groups were compared.Results The gestational age,birth weight,placental weight of the obseruation group was signiticantly higher than thal of the control group ( t =4.55,2.79,11.91,all P ＜ 0.05 ),while FGR,oligohydramnies,fetal distress and the incidence of hypertensive disorters of the obseruation group were significantly lower than that of control group ( x2 =6.50,20.55,7.87,3.76,all P ＜ 0.05 ) ; Compared to the control group,the observation group didn't have higher incidence of intrauterine fetal death,neonatal asphyxia and perinatal death ( P ＞ 0.05).Conclusion Low molecular weight heparin using in early pregnancy was effective in preventing FGR in pregnant women with FGR risk factors.

Background Electroacupuncture pretreatment plays a protective role in myocardial ischemia/reperfusion (I/R) injury and microRNAs (miRNAs) could act on various facets of cardiac function. However, the role of miRNAs in the cardioprotection by electroacupuncture pre-treatment on myocardial I/R injury remains unknown. The purpose of the study was to examine whether miR-214 was involved in cardio-protection by electroacupuncture. Methods Using rat myocardial I/R model, we examined the role of electroacupuncture pretreatment in myocardial I/R injury and analyzed the changes in the expression of miR-214. In addition, I/R was simulated in vitro by performing oxy-gen-glucose deprivation (OGD) on H9c2 cell cultures, and the effect of electroacupuncture pretreatment on I/R injury as well as expressional level of miR-214 were examined in vitro. Furthermore, the miR-214 mimic was transfected into OGD-treated H9c2 cells, we analyzed the cell apoptosis, lactate dehydrogenase (LDH) and creatine kinase (CK) activities, intracellular free Ca2+concentration ([Ca2+]i) as well as the relative protein levels of sodium/calcium exchanger 1(NCX1), BCL2-like 11 (BIM), calmodulin-dependent protein kinase IIδ(CaMKIIδ) and Cyclophilin D (CypD). Results The in vivo results revealed that compared with the I/R group, the electroacupuncture pretreatment group showed significant decreased myocardial infarct size, as well as the increased indices of the cardiac function, including heart rate, mean arterial pressure, left ventricular systolic pressure and maximal rate for left ventricular pressure rising and declining (±dp/dt max). In addition, electroacupuncture pretreatment could inhibit the elevation of LDH and CK activities induced by I/R injury. The quantitative PCR (qPCR) results demonstrated electroacupuncture pretreatment could provide cardioprotection against myocardial I/R injury in rats with miR-214 up-regulation. In the meanwhile, in vitro, electroacupuncture pretreatment protected H9c2 cells from OGD-induced injury. Trans-fection of miR-214 mimic showed protective effects on OGD-induced injury to H9c2 cells by reducing apoptosis, decreasing LDH and CK activities, rescuing the OGD-induced Ca2+and down-regulating elevated protein levels of NCX1, BIM, CaMKIIδand CypD. Conclusions Our findings firstly demonstrated that electroacupuncture pretreatment promotes the expression of miR-214 in myocardial I/R injury and miR-214 contributes to the protective effect of electroacupuncture on myocardial I/R injury.

Objective To describe the prevalence and risk factors of suicidal ideation and suicide attempt among community patients and their family members in Beijing.Methods Accidental sampling method was used in this cross-sectional study to select patients and their family members who visited a community healthcare center in Beijing from June to September 2008.The subjects were required to complete essential information questionnaire,Beck Depression Inventory,Beck Anxiety Inventory and Beck Hopelessness Scale.Chi-square test and binary logistic regression were used to learn the risk factors of suicidal ideation and suicide attempt.Results A total of 2791 valid questionnaires were collected,with a response rate of 90.0％.The participants included 1074 males and 1717 females with mean age (36.8±13.1)years old.The one-year prevalence of suicidal ideation and suicide attempt was 2.8％ (77/2791) or 1.1％ (30/2791),respectively.The one-year prevalence of suicidal ideation was significantly different among the subjects with different professions (x2=12.512,P=0.006),negative events (x2=53.287,P＜0.001),family history of suicide (x2=103.922,P＜0.001),family history of psychiatry diseases (x2=20.640,P＜0.001),hopelessness (x2=77.337,P＜0.001),depression (x2=135.918,P＜0.001) and anxiety (x2=70.303,P＜0.001).The one-year prevalence of suicidal attempt was statistically different among the subjects with different professions (x2=7.954,P=0.037),family history of psychiatry diseases (x2=6.257,P=0.003),hopelessness (x2=29.838,P＜0.001),depression (x2=21.352,P＜0.001) and anxiety (x2=10.014,P＜0.001).Multivariate logistic analysis found that the most important risk factors of suicidal ideation were depression (for mild,moderate and severe depression:odds ratio (OR) 2.38,5.55 and 16.21,respectively; 95％ confidence internal (CI) 1.07-5.31,2.31-13.37 and 6.93-37.92,respectively),family history of suicide (OR=1 1.68,95％CI 5.03-27.10),hopelessness (for mild,moderate and severe hopelessness:OR 3.65,4.25 and 5.02,respectively; 95％ CI 1.55-8.56,1.70-10.65 and 1.46-17.26,respectively),negative life events (OR=2.25,95％ CI 1.35-4.45).The most important risk factors for suicide attempt were hopelessness (for mild,moderate and severe hopelessness:OR 1.09,5.58 and 7.62,respectively; 95％ CI 0.36-3.34,2.03-15.30 and 1.50-38.72,respectively),depression (for mild,moderate and severe depression:OR 1.08,0.27 and 3.02,respectively; 95％ CI 0.43-2.75,0.03-2.29 and 1.05-8.75,respectively) and family history of psychiatry diseases (OR=3.00,95％CI 1.07-8.46).Conclusions Hopelessness and depression could increase the risk of suicide behaviors.Family clinicians should be trained to identify such risk tactors and provide appropriate mental health intervention.

The roots of Glycyrrhiza uralensis are widely used in Chinese medicine for their action of clearing heat, detoxicating, relieving cough, dispelling sputum and tonifying spleen and stomach. The reason why Glycyrrhiza uralensis has potent and significant actions is that it contains various active secondary metabolites, especially glycyrrhizic acid. In the present study, we cloned the cDNA coding 3-hydroxy-3-methylglutary CoA reductase (HMGR) involved in glycyrrhizic acid biosynthesis in Glycyrrhiza uralensis. The corresponding cDNA was expressed in Escherichia coli as fusion proteins. Recombinant HMGR exhibited catalysis activity in reduction of HMG-CoA to mevalonic acid (MVA) just as HMGR isolated from other species. Because HMGR gene is very important in the biosynthesis of glycyrrhizic acid in Glycyrrhiza uralensis, this work is significant for further studies concerned with strengthening the efficacy of Glycyrrhiza uralensis by means of increasing glycyrrhizic acid content and exploring the biosynthesis of glycyrrhizic acid in vitro.

Objective To investigate the risk factors of gallstone disease in Inner Mongolia populations.Methods A case-control study was conducted in 180 consecutive patients who had undergone cholecytectomy for gallstones in the hospital of Inner Mongolia during December 2010 to December 2011.Another 200 patients (age 19 to 81 years old) with no gallstone disease were enrolled as controls.All the participants completed a questionnaire and took physical or ultrasonographic examinations.Univariate analysis and Multivariate logistic regression analysis were used for data analysis.Results Mean age of the study group and the control group was (51.7 ± 13.2) and (54.6 ± 12.1) years old,respectively.More female patients were found in the study group (130:50,x2 =9.552,P ＜ 0.05).After adjusting age and gender,multivariate logistic regression showed that gallstone disease was significantly associated with higher educational level (OR =7.05; 95％ confidence internal (CI):1.28-38.85),animal viscera intake (OR =12.75,95 ％ CI:4.67-34.82),fried food intake (once and twice a week:OR =9.04,95％ CI:4.67-17.51; twice a week:OR=5.39,95％ CI:1.60-18.21) and dyslipidaemia (OR=2.81,95％ CI:1.49-5.30).Vegetables intake (2-3 times a week:OR =0.28,95％ CI:0.03-2.65 ; 4-5 times a week:OR =0.09,95 ％ CI:0.01-0.80 ; once a day:OR =0.02,95％ CI:0.002-0.19) was inversely associated with gallstone disease.Risk factors of gallstone disease were different by genders.Conclusions Animal viscera or fried food intake and dyslipidaemia may increase the risk of gallstone disease.However,vegetables intake may prevent the development of gallstone disease.

Objective To evaluate the effect of captopril and isoflurane preconditioning on cell apoptosis during myocardial ischemia/reperfusion (I/R) in rabbits.Methods Forty New Zealand white rabbits of both sexes,weighing 1.8-2.5 kg,were randomly divided into 5 groups (n =8 each) using a random number table:sham operation group (group S),group I/R,isoflurane preconditioning group (group I),captopril preconditioning group (group C) and captopril and isoflurane preconditioning group (group C + I).The animals were anesthetized with 3％ pentobarbital sodium 30 mg/kg.Myocardial ischemia was induced by occlusion of the left anterior descending branch of coronary artery for 30 min followed by 120 min of reperfusion.1.1％ isoflurane was inhaled for 30 min followed by 15 min washout before myocardial ischemia in group I.Captopril 25 mg/kg was given through a gastric tube into the stomach at 24 h before myocardial ischemia in group C.Captopril 25 mg/kg was given through a gastric tube into the stomach,24 h later 1.1％ isoflurane was inhaled for 30 min followed by 15 min washout,and then myocardial ischemia was performed in group C + I.The rabbits were sacrificed at the end of reperfusion and myocardial specimens were removed for microscopic examination and observation of ultrastructure,and for determination of the expression of Bcl-2 and Bax proteins (by Western blot).The apoptosis rate was detected by flow cytometry.Bcl-2/Bax ratio was calculated.Results Compared with group S,the apoptosis rate was significantly increased,the expression of Bcl-2 and Bax proteins was up-regulated,and Bel-2/Bax ratio was decreased in I/R,I,C and C + I groups (P ＜ 0.05).Compared with I/R,I and C groups,the apoptosis rate was significantly decreased,Bcl-2 protein expression was up-regulated,Bax protein expression was down-regulated,and Bcl-2/Bax ratio was increased (P ＜ 0.05),and the pathological changes were significantly attenuated in group C + I.Conclusion Regulation of Bcl-2/Bax ratio and inhibition of apoptosis in myocardial cells are involved in the mechanism by which isoflurane and captopril preconditioning reduces I/R injury in rabbits.

Objective To evaluate 10-year risk of ischemic cardiovascular diseases (ICVD) in middle-aged adults in Henan province to provide evidence for improved health status. Methods The 10- year risk of ICVD in 12 064 middle-aged adults was evaluated by using simplified risk estimation model. Results About 96. 35% of male and 98. 29% of female had a probability of < 10% to develop ICVD over 10 years; 3.65% of male and 1.71% of female had a probability of ≥ 10% to develop ICVD over 10 years; and 0.68% of male and 0.23% of female had a probability of≥20% to develop ICVD over 10 years. The prevalence of risk factors for ICVD in two absolute risk groups ( ≥10% vs < 10% ) was significantly different. Conclusions The risk of ICVD in the middle-aged residents of Henan province may be similar to that in the middle-aged Chinese adults. The risk assessment for ICVD could be used for high- risk populations.

Objective To investigate the effects of perioperative intraperitoneal chemotherapy with 5-fluorouracil (5-FU) sustained release agent on the local recurrence and survival rates of patients with advanced gastric cancer. Methods The clinical data of 100 patients with advanced gastric cancer who had been admitted to our hospital from January 2002 to December 2004 were retrospectively analyzed. All patients were divided into treatment group and control group. Only patients in the treatment group were implanted with 5-FU sustained release agent (800 mg) in abdominal cavity after D2 gastrectomy. All patients accepted chemotherapy according to the FOLFOX regimen. Results The 3-year survival rate and 3-year disease free survival rate were 45% and 28% for treatment group, which were significantly higher than 32% and 16% for control group. Conclusions Intraperi-toneal implantation of 5-FU sustained release agent during operation can decrease local recurrence rate and improve the 3-year survival rate of patients with advanced gastric cancer after radical gastrectomy.
