Objective To investigate the prevalence of small intestinal bacteria overgrowth (SIBO)in patients with minimal hepatic encephalopathy (MHE). Methods Ninety patients with cirrhosis and 20 healthy volunteers were studied. All of them were assessed with glucose hydrogen breath test (GHBT) to detect SIBO. And number connection test (NCT-A, NCT-BC) and digit symbol test (DST) were used to diagnose MHE. Results One case (5.0%) out of 20 healthy volunteers was SIBO and none was MHE,and 28 cases (31.1%) out of 90 cirrhosis patients were SIBO and 38 cases (42.2%) were MHE. Twenty-one (55.3%,21/38) cases were diagnosed as SIBO among these patients with MHE,and 7 cases (13.5%,7/52)were diagnosed as SIBO among these patients without MHE. There was significant difference between cirrhosis with MHE and cirrhosis without MHE (x2 = 17.90,P＜ 0.01 ). Conclusions Patients with cirrhosis have a higher prevalence of SIBO. The incidence rate of SIBO in cirrhosis patients with MHE is more than that without MHE.

Objective To investigate the correlations between the occurrence of carotid artery atherosclerosis and chlamydia pneumoniae (Cpn) and cytomegalovirus (CMV).Methods Carotid color ultrasonography showed that the patients with intima-media thickness (IMT) ＞ 1.5 mm were enrolled and were used as a carotid atherosclerosis group,and the healthy subjects (IMT ＜ 1.0 mm) were used as a control group.Enzyme-linked immunosorbent assay (ELISA) was used to detect the antibody levels and positive rates of the serum anti-Cpn and anti-CMV IgG.The demography,vascular risk factors,anti-Cpn and anti-CMV IgG antibody positive rates of the carotid atherosclerosis group and the control group were compared.Results A total of 92 patients of the carotid atherosclerosis group were enrolled,including 30 patients with stable plaque and 62 with unstable plaque; a total of 49 healthy subjects of the control group were enrolled.There were no significant differences in the proportions of age,male,hypertension,diabetes,hyperlipidemia,and smoking patients between the carotid atherosclerosis group and the control group (all P ＞0.05).The anti-Cpn IgG (69.5％ vs.26.5％ ; x2 =23.887,P ＜ 0.001),anti-CMV IgG positive rate (75.0％ vs.30.6％ ; x2 =26.156,P ＜ 0.001),and anti-Cpn IgG + anti-CMV positive rate (51.2％ vs.10.2％ ;x2 =24.006,P ＜0.001) of the carotid atherosclerosis group were significantly higher than those of the control group.In the atherosclerosis group,there were no significant difference in the proportions of age,male,hypertension,diabetes,hyperlipidemia,and smoking patients between the unstable plaque subgroup and the stable plaque subgroup (all P＞ 0.05).The anti-Cpn IgG (80.6％ vs.46.7％; x2=11.025,P=0.001),anti-CMV IgG positive rate (83.9％ vs.56.7％;x2 =7.980,P=0.005) and anti-Cpn IgG + anti-CMV positive IgG rate (44.6％ vs.7.6％ ; x2 =10.210,P =0.006) of the unstable plaque subgroup were significantly higher than those of stable plaque subgroup.Conelusions The occurrence of carotid atherosclerosis and the stability of plaque are associated with the Cpn and CMV infection.The Cpn and CMV infection may be the important factors for the occurrence of carotid atherosclerosis plaques and unstable plaques.

Objective To investigate the changes of right ventricular(RV) volume and function in patients with atrial septal de-fect(ASD) .Methods 31 patients with ASD-type secundum(ASD group) and 30 age-matched controls(control group) were includ-ed .Single beat real-time three dimensional echocardiography (sbRT3DE) were performed in all to evaluate right ventricular volume and function ,then right venrtricular cardiac output(RVCO) were calculated with heart rate .Further correlative analysis was calcu-lated between right ventricular volume and function parameters of the ASD group and ASD size and the patient′s age .Results Right ventricular end-systolic volume(RVESV) ,right ventricular end-diastolic volume(RVEDV) ,right ventricular stroke volume (RVSV) ,right ventricular ejection fraction(RVEF) ,RVCO of the ASD group were significantly higher than that of control group (P<0 .001) .The maximum diameter of ASD had positive relation with RVESV ,RVEDV ,RVSV ,RVCO(r=0 .55 ,P<0 .01 ;r=0 .61 ,P<0 .01 ;r=0 .63 ,P<0 .01;r=0 .61 ,P<0 .01 ,respectively ) ,and was best correlation with RVSV .But ,there was no signifi-cant correlation between the maximum diameter of ASD and RVEF (r=0 .00 ,P>0 .05) .The patients′age had positive relation with RVESV ,RVEDV ,RVSV(r=0 .53 ,P<0 .01 ;r=0 .48 ,P<0 .01 ;r=0 .41 ,P<0 .01 ,respectively) ,had negtive relation with RVEF (r= -0 .44 ,P<0 .05) ,while there was no significant correlation between the patient′s age and RVCO(r=0 .26 ,P>0 .05) .Conclu-sion sbRT3DE is a fast and accurate new technology in evaluating RV volume and function .Atrial level left-to-right shunt leading to an increase in RV volume ,RV enlargement produces myocardial contractility .RV volume increases with ASD size ,then RV func-tion was enhanced .RV volume increases with patient′s age ,RV function is relatively lower .

Objective To optimize the extraction process of Euphorbia hirta L.by Central composite design/response surface methodology with ethanol by the ultrasonic extraction technology.Methods Based on the single factor experiment and central composite design-response surface methodology,the content of quercitroside was regarded as evaluation index,select ethanol concentration,extraction time,and solid-liquid ratio as three evaluation factors to achieve the purpose. Results The results indicated that the optimal extraction process was obtained as follows:10 times the amount of 60% ethanol under ultrasound for 2 times,50 min each;the average content of the quercitroside was 2.39 mg/g.Conclusion The method to optimize the extraction process is simple and reasonable.

Objective:To investigate the effect of fresh food homogenate instead of traditional liquid and semiliquid diet on the condition of nutrition and aspiration in the early stage of pulling out the na-sogastric tube in patients with moderate dysphagia.Methods:Forty patients with tube feeding were randomly divided into observation group and control group.Each group had 20 cases.After extubation,the observation group ate fresh food homogenate,and the control group were feeding liquid and semi liquid diet.The actual calories intake,protein,carbohydrate,lipid and dietary fiber were recorded on the first day and the fifteenth day of intervention.The values of serum albumin,prealbumin,hemoglobin and total lymphocyte count were measured.The rate of aspiration and constipation was observed continuously during the study.Results:After 2 weeks of intervention,the daily energy and nutrient intake,nutritional biochemical indexes of observation group were higher than those of control group (P ＜ 0.05),and the incidence of aspiration and constipation was decreased in observation group (P ＜ 0.05).Conclusion:Compared with the conventional liquid and semi liquid diet,fresh food homogenate can increase the intake of daily calorie and nutrition in patients with moderate dysphagia in the early stage after the feeding tube was pulled out,improve nutritional status,reduce the aspiration and constipation,and be well tolerated.
