Objective To explore the multiple risk factors for family lifestyle of children with congenital heart defects (CHDs) in Shaanxi Province, China. children and their parents. The univariate and multivariable logistic regression models were used to analyze the influence of risk factors related to parents' lifestyle on CHDs. Results Several possible risk factors were found for CHDs, including fever (OR=4.465, P=0.017), pesticides contact (OR=2.234, P=0.083), passive smoking during pregnancy (OR=20.529, P=0.007) and father's smoking (OR=3.342, P=0.005); fever (OR=2.428, P=0.012) and passive smoking during pregnancy (OR=1.201, P=0.037) were also correlated with ventricular sepal defect (VSD). Conclusion Fever, pesticides contact and passive smoking are associated with CHDs during pregnancy. We should focus our attention on health care during pregnancy to avoid the above-mentioned risk factors and call on parents to hold on to a good healthy lifestyle.

BACKGROUNDDiabetic nephropathy is a major cause of renal failure in diabetes mellitus (DM). It has been known that renin-angiotensin system (RAS) blockers have a renal protective effect. This study aimed to investigate whether treatment with angiotensin II receptor blocker, olmesartan, could modify renal hemodynamic variables and vascular structural properties, then attenuate renal injury in streptozotocin (STZ)-induced DM rats.
METHODSDM was induced in male Wistar rats by intraperitoneal administration of STZ. The rats were then randomized to a DM group and an olmesartan treatment (OLM + DM) group. The normal group (non-DM) were administered only citrate buffer. At the end of the 14th week, blood glucose, kidney weight/body weight and urinary protein-to-creatinine ratio were determined. Further, the flow-pressure and pressure-glomerular filtration rate (GFR) relationships were determined for maximally vasodilated, perfused kidneys. From the relationship, 3 indices of vascular structural properties were estimated: slope of flow-pressure (minimal renal vascular resistance, reflecting overall luminal dimensions of preglomerular and postglomerular vasculature), slope of pressure-GFR (glomerular filtration capacity against pressure) and threshold pressure for beginning filtration at pressure-GFR (preglomerular to postglomerular vascular resistance ratio). Kidneys were then perfusion fixed for histological analysis. The renal histopathology was observed by light microscopy.
RESULTSThe body weight of DM rats was lower than that of non-DM rats. Blood glucose, kidney weight/body weight, urinary protein-to-creatinine ratio were significantly greater in DM rats than in non-DM rats. The parameters such as kidney weight/body weight, urinary protein-to-creatinine ratio in OLM + DM rats had dramatically decreased compared with those in DM rats. However, the treatment with olmesartan had no effect on blood glucose levels. The slope of flow-pressure relationship was greater in DM rats than that in non-DM rats (P < 0.05). But the slope of the pressure-GFR relationship was lower in DM rats than that in non-DM rats (P < 0.05) with the x-intercept of the line similar between the two groups. The slope of the flow-pressure relationship was decreased in DM rats group treated with olmesartan (P < 0.05). Moreover, olmesartan significantly increased the slope of the pressure-GFR relationship in DM rats (P < 0.05). The x-intercept of the pressure-GFR relationship reduced following olmesartan in DM rats.
CONCLUSIONSTreatment with olmesartan reduced urinary protein-to-creatinine ratio independent of blood glucose and increased average renal vessel lumen diameter in the perfused kidneys of STZ-induced DM rats, predominantly in preglomerular vessels, and then improved renal excretory capability. These findings were consistent with remodeling of the preglomerular vasculature in our hisological measurements.

OBJECTIVETo observe the intervention effect of acupuncture on early onset of selec- tive serotonin reuptake inhibitors (SSRIs) in treating depressive disorder, and to study its effect on ser- um 5-HT and unbalanced inflammatory cytokines secreted by TH1/TH2.
METHODSTotally 90 patients with depressive disorder were randomly assigned to the drug control group (as the control group, 45 cases) and the acupuncture combined drug treatment group (as the treatment group, 45 cases). All patients were treated for 4 consecutive weeks. Another 45 healthy subjects were recruited as a healthy control group. The effect of acupuncture on early onset of SSRls in treating acute phase depressive disorder pa- tients was evaluated by HAMD score in the control group and the treatment group before treatment,and at weekends of the 1st, 2nd, and 4th week after treatment. Besides, their serum levels of 5-HT, IL-1β and IL-6 (secreted by TH1), and IL-4 and IL-10 (secreted by TH2) were detected before treatment and after treatment at the weekend of the 4th week.
RESULTSCompared with the healthy control group,serum lev- els of 5-HT, IL-4, and IL-10 decreased in the two drug-treated groups before treatment (P < 0.01); serum levels of IL-1β and IL-6 increased (P <0.01). Compared with before treatment in the same group, HAMD score decreased in the control group at weekends of the 2nd and the 4th week after treatment (P < 0.01); HAMD scores decreased in the treatment group at weekends of the 1st, 2nd, 3rd,and 4th week after treatment (P < 0.01); serum levels of 5-HT, IL-4, and IL-10 increased,serum levels of IL-1β and IL- 6 decreased in the two drug-treated groups after treatment (all P < 0.01). Compared with the control group at the same time point,HAMD scores decreased in the treatment group at weekends of the 1st, 2nd,3rd,and 4th week after treatment (P < 0.01),serum levels of 5-HT, IL-4, and IL-10 increased (P < 0.05, P < 0.01), serum levels of IL-6 decreased (P < 0. 01).
CONCLUSIONAcupuncture could accelerate early onset of SSRIs in treating acute phase depressive disorder, and effectively regulate serum 5-HT levels and inflammatory cytokines secreted by TH1/TH2.

BACKGROUNDAs the incidence of type 2 diabetes is rapidly increasing, prevention of the disease should be considered as a crucial objective in the near future. Several studies have shown angiotensin receptor blockers (ARBs) may contribute to the prevention of new-onset type 2 diabetes. This study was conducted to determine if ARBs as monotherapy or combination therapy may experience a decreased incidence of new-onset type 2 diabetes and prevent cardiovascular events.
METHODSRelevant experimental and clinical studies were identified by searching MEDLINE (1969 to May 30, 2011) to extract a consensus of trial data involving the effect of ARBs on prevention of new-onset type 2 diabetes and cardiovascular events. Studies were included if they were randomized controlled trials versus placebo/routine therapy. A random-effects model was utilized. Subgroup and sensitivity analyses were conducted.
RESULTSEleven trials were identified, including 82 738 patients. ARBs prevented new-onset type 2 diabetes (odds ratio 0.8 (95%CI 0.76, 0.85)). Regardless of indication for use, essential hypertension (seven trials), impaired glucose tolerance (one trial), cardiocerebrovascular disease (two trials) or heart failure (one trial), reductions in new-onset type 2 diabetes were maintained (0.75 (0.69, 0.82), 0.85 (0.78, 0.92), 0.80 (0.76, 0.85) and 0.80 (0.64, 0.99), respectively). No statistical heterogeneity was observed for any evaluation. However, ARBs did not significantly reduce the odds of all-cause mortality, myocardial infarction and heart failure versus control therapy among all of these studies. But ARBs did reduce the odds of cardiac death and heart failure among the heart failure study versus control therapy.
CONCLUSIONARBs have significant ability to reduce risk of developing new-onset type 2 diabetes but does not improve cardiovascular outcomes over the study follow-up periods among all of included studies.

OBJECTIVESTo explore the effects of endotoxemia on gluconeogenesis in livers and kidneys during acute hepatic failure.
METHODTwenty-four healthy male SD rats were randomly divided into four groups (6 rats in each group) and all of them were injected intraperitoneally with solutions: group I with normal saline, group II with 400 mg/kg of D-galactosamine (D-GaLN), group III with 400 mg/kg of D-GaLN plus 50 microg/kg lipopolysaccharide(LPS), and group IV with 400 mg/kg of D-GaLN plus 500 microg/kg LPS. At 6 hours after the administration of different solutions intraperitoneally, blood samples were collected to examine blood urea nitrogen (BUN) and serum creatinine. Realtime PCR was used to study the expression of phosphoenolpyruvate carboxykinase (PEPCK) in the livers and kidneys.
RESULTSNo endotoxemia developed in group I or group II but it was evident in group III and group IV. The level of endotoxemia in group IV was higher than in group III (8.05+/-0.43, 3.50+/-2.25, P<0.05). After 6 hours of administration of LPS in group IV, hypoglycemia appeared, and blood glucose was normal in the other three groups. BUN and serum creatinine were all normal in the four groups, except that blood urea nitrogen was elevated in group IV. The mRNA of PEPCK in livers decreased gradually in all the four groups (2.54+/-1.32 vs 1.87+/-0.15 vs 0.91+/-0.13 vs 0.44+/-0.42, P<0.05). In the kidneys there was no change in the expression of PEPCK in group I and group II (0.75+/-0.03 and 0.77+/-0.04, P>0.05), but it increased in group III (0.75+/-0.03 vs 1.63+/-0.86, P<0.05), and decreased in group IV (0.75+/-0.03 vs 0.13+/-0.07, P<0.05).
CONCLUSIONDuring acute hepatic failure severe endotoxemia would damage the function of gluconeogenesis in livers and kidneys by inhibiting transcription of PEPCK and this can induce hypoglycemia.

OBJECTIVETo explore the role of glutamine in LPS and D-Gal induced acute hepatic injury.
METHODSA total of 61 Wistar rats were randomly divided into three groups: control group, model group and GLN pretreated group. The animal model was established by LPS and D-Gal intraperitoneal injection. GLN at dose of 1 g/kg was intragastrically administrated for 7 d before intraperitoneal injection. To evaluate the hepatic injury, the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBiL) were detected by automatic biochemistry analysator. The liver and bowel tissue was observed by lightmicroscope and transmission electron microscope (TEM). The apoptosis of hepatocyte was detected by TUNEL. HPLC-PED was used in the study of intestinal permeability.
RESULTSNo significant differences were noted between ALT, AST, TBIL level, death rate and intestinal permeability (L/M) between model group and GLN pretreated group; In microscope, the confused structure of hepatic injury and inflammatory infiltration were similar between model group and GLN pretreated group. The injury of bowel was not obviously. Compared with the model group, there was better trend in liver and bowel in GLN pretreated group by transmission electron microscope (TEM). The apoptosis index in GLN pretreated group were lower than those in model group.
CONCLUSIONLPS can induce acute liver injury in D-Gal-sensitized rats.Glutamine has't the trend of protecting liver function and intestinal barrier function,decreasing death rates.

OBJECTIVETo explore the impact of environmental factors, daily lifestyle, psycho-social factors and the interactions between environmental factors and chemokines genes on systemic lupus erythematosus (SLE).
METHODSCase-control study was carried out and environmental factors for SLE were analyzed by univariate and multivariate unconditional logistic regression. Interactions between environmental factors and chemokines polymorphism contributing to systemic lupus erythematosus were also analyzed by logistic regression model.
RESULTSThere were nineteen factors associated with SLE when univariate unconditional logistic regression was used. However, when multivariate unconditional logistic regression was used, only five factors showed having impacts on the disease, in which drinking well water (OR=0.099) was protective factor for SLE, and multiple drug allergy (OR=8.174), over-exposure to sunshine (OR=18.339), taking antibiotics (OR=9.630) and oral contraceptives were risk factors for SLE. When unconditional logistic regression model was used, results showed that there was interaction between eating irritable food and -2518MCP-1G/G genotype (OR=4.387). No interaction between environmental factors was found that contributing to SLE in this study.
CONCLUSIONMany environmental factors were related to SLE, and there was an interaction between -2518MCP-1G/G genotype and eating irritable food.

OBJECTIVETo study the effect of Yangqixue Qufengshi Recipe (YQXQFS) on rheumatoid arthritis (RA) model mice under different genetic backgrounds.
METHODSCollagen Induced Arthritis (CIA) were established on HLA-DR4 transgenic (TG) mice and non-transgenic (NTG) mice, which partly were raised with YQXQFS, and the onset day of CIA, the level of type II collagen (CII)-reactive antibodies and the pathological scores of CIA were assessed.
RESULTSUnder HLA-DR4 TG background (compared with NTG mice), the earlier onset day of CIA (11.22 +/- 3.35 days vs 16.56 +/- 4.75 days, P < 0.05) and higher level of CII-reactive antibodies (0.2274 +/- 0.1390 microg/ml vs 0.1101 +/- 0.0560 microg/ml, P < 0.05) were observed, but the pathological scores of CIA remained unchanged. YQXQFS could not influence the onset day of CIA and the level of CII-reactive antibodies, but had a certain effect on the total pathological scores (6.56 +/- 3.43 scores vs 11.11 +/- 5.64 scores) and bone erosion (0.22 +/- 0.44 scores vs 1.67 +/- 1.50 scores) of CIA on NTG mice (P < 0.05), NTG YQXQFS group compared with NTG experimental group.
CONCLUSIONYQXQFS had a certain effect on RA model, but had no significant effect on HLA-DR4 related CIA.

OBJECTIVETo study clinic character of liver failure complicated with bacterium and fungous infection.
METHODSThe patients with liver failure complicated with bacterial and fungous infection who were treated in our hospital from January 1986 to June 2006 were studied. All patients had clinical manifestation and positive of bacterium. The data were statistical analysis.
RESULTS507 patients diagnosed with fungous infection were found from January 1986 to June 2006 in which 132 patients were diagnosed with bacterial and fungous infection. There were 85 patients (64.39%) with chronic severe hepatitis and 40 patients (30.3%) with decompensation cirrhosis. Bacterial infection happened in 153 cases in which the rate of nosocomial infections was 54.90%. 204 bacterial strains were separated in which 143 strains (70.10%) were gram-negative bacterium and 61 (29.90%) strains were gram-positive bacterium. The main sites of bacterial infection were abdominal cavity (122 cases) and lung (30 cases). Fungous infection happened in 143 cases in which the rate of nosocomial infections was 86.71%. 155 fungous strains were separated in which 90 strains (58.06%) were Candida albicans, 17 strains (10.97%) were Aspergillus fumigatus and 25 (16.13%) strains were non-Candida albicans. The main sites of fouguns infection were lung (94 cases) and mouth (53 cases). 84 patients (63.64%) were ineffective and died after treatment.
CONCLUSIONThe patients with decompensation cirrhosis and chronic severe liver hepatitis were easy to be infected by bacterial and fungous. the rate of fungous nosocomial infections is higher than that of bacterium. The prognosis is bad in patients who had secondary fungous infection.
