Objective To study the role of recombinant human epidermal growth factor (rhEGF) in the prognosis of multiple organ dysfunction syndrome (MODS) in mice. Methods One hundred and twenty clean male Kunming mice were randomly ( random number) divided into normal saline control group (n =15),MODS model control group (n =15) and MODS + rhEGF treatment group (n =90).The MODS models were made by using Caballero ME method with thioacetamide (TAA) 2000 mg/kg injected intraperitoneally to establish monophasic rapid onset pattern of MODS model in mice.MODS + rhEGF treatment group was further randomly divided into two subgroups,namely intraperitoneal injection group (n =45 ) and subcutaneous injection group (n =45 ).Each subgroup was divided again into three small subgroups (n =15) as per different doses of rhEGF used,namely 10 μg/kg,30 μg/kg and 50 μg/kg.Within 24 hours after modeling,the respiration,body weight,food eaten and general physical changes were observed.Mortality was calculated 24 hours after modeling.After the animals sacrificed,the tissues of viscus including liver,kidney,heart,brain,lung,spleen,pancreas,intestine and stomach were collected immediately.The histological changes of visceral tissues were studied by using hematoxylin -eosin staining under the light microscope.All the experimental data were presented in,and body weight changes were compared using t-test,and after different routes of administration with different doses of rhEGF used in MODS,the mice body weight changes were analysed by using the Dunnett method,and the mortalities of mice were compared by using Fisher exact test,and P ＜ 0.05 was considered statistically significant difference. Results There was no significant difference in mortality betweeu mice in rhEGF subcutaneous administration group and MODS model control group (P ＞ 0.05 ),but the total mortality of hrEGF MODS intraperitoneal administration group (6.7％ in dose of 50 μg/kg and 20％ in dose of 30 μg/kg) was significantly lower than that of MODS model control group (73.3％) ( P ＜ 0.05 ) and the mortality of mice treated with intraperitoneal 50μg/kg rhEGF (6.7％ ) was lower than that treated with 10μg/kg rhEGF (P=0.014).The mortality of mice in rhEGF MODS (50 μg/kg ) intraperitoneal administration group was significantly lower than that in subcutaneous administration group (40％) (P =0.031 ), The histopathological changes in rhEGF MODS treatment group were not as remarkable as seen in mice of control group.The histopathological changes were dose - dependent.The higher doses of rhEGF,the lesser hepatic congestion,liver cell apoptosis,hepatic cell cloudy swelling and cell vacuolization.Similarly,as RhEGF dosage increased,pulmonary interstitial congestion,inflammatory cells and apoptotic bodies reduced,and bronchial ciliated columnar epithelium less shed.Conclusions RhEGF plays a positive role in repairement of tissue damage in TAA - induced MODS murine model.The rhEGF given by intraperitoneal route of administration is more effective to reduce the 24 h mortality of MODS mice than that by subcutaneous route.

Objective To study the clinical features of Crohn's disease(CD)at different location,I.e.small intestine.colon and ileocolon,to facilitate the knowledge of the disease.Methods Data of 103 patients,hospitalized to our department from 2000 to January 2008,were retrospectively analyzed,including general status,clinical manifestations,laboratory findings and pathological changes.Results The cohort included 70 males and 33 females,with the age when the diagnosis was confirmed ranging from 12 to 70,with a peak at 20-29 yr.The location of the main lesion was at small bowel(L1)in 39(38%),at colon (L2)in 16(16%)and at ileum-colon(L3)48(46%).There was no significant difference between each group,regarding the age of onset or the when the diagnosis was confirmed.The incidence of intestinal obstruction was higher in L1 patients than that in L3(P＜0.05).In group L1,12(30.8%)were diagnosed by capsule endoscopy,and 17(44%)were confirmed by colonoscopy.Diagnostic rates of L2 and L3 with reference to clinical manifestations.combined with colonoscopy and pathology were 87.5%and 83.3%,respectivelv.In this cohort,there were 23(22.3%)mild cases,58(56.3%)moderate cases and 22 (21.4%)severe cases,according to simplified CD activity index(CDAI).The rate of severe case in L3 was 59.0%(13/48),which was significantly higher than that in L1(P＜0.05).Conclusion In patients with CD,L1 is characterized by delayed diagnosis and need of emergent surgery,while L3 is featured with extensive involvement.severe complications and systemic manifestations.Severe case is common in 13 patient,capsule endoscopy and Colonoscopy are important in early detection of the disease to decrease operation rate and delay the time of first operation.

Objective To investigate the effect of drug dependence severity on the relationship between impulsivity and craving.Methods 36 abstiuent drug-dependent individuals were recruited in the study.The participants were divided into the heavy depeudence group (HDG) or the low dependence group (LDG) according to the scores of Addiction Severity Index (ASI).The Barratt Impulsiveness Scale (BIS-11) and classical Stroop task were used to measure the trait impulsivity and state impulsivity.Block designed cue-induced craving paradigm was presented to measure cue-elicited craving.Results For the HDG,a significant positive correlation was found between trait impulsivity (the mean value of BIS-11-CI scale was (39.03± 16.50)) or state impulsivity (the difference of reaction time between congruent and incongruent situation was (87.77±36.95)ms)and cue-elicited craving (0.83± 1.91)(r=0.487,0.500,P＜0.05).However,for the LDG subjects,the impulsivity was not found significantly correlated with the cue-elicited craving(r=-0.261,0.081,P＞0.05).Conclusion The addiction severity influences the relationship between impulsivity and craving,and impulsivity can only be used as a predictor of relapse in HDG.The findings suggest that the drug may influence the shared brain mechanism between impulsivity and craving.

Objective To investigate esophageal response to intraesophageal balloon-distention and acid perfusion stimuli and to evaluate the visceral hypersensitivity in non erosive reflux disease (NERD) patients.Methods Thirty-one NERD patients diagnosed by reflux disease questionnaire (RDQ) and endoscopy and 10 control subjects were enrolled in this study.Esophageal mechanical sensitivity was measured by esophageal barostat and recorded as initial perception threshold and maximal tolerated pain threshold by volume.The chemical sensitivity was measured by acid perfusion test,and quantified by two parameters (trigger time and acid related symptom score).Results Initial perception threshold and maximally tolerated pain threshold of NERD patients was (9.6?4.8) ml and (12.3?3.2) ml, significantly lower than those of controls,(13.2?7.5) ml and (21.6?5.7) ml,respectively (P

Objective To set up the technology for adsorbing and separating total flavone in Sarcandra glabra with macroporous adsorption resin,11 types of macroporous adsorption resins were investigated.Methods The static adsorption and separation were used in investigation of macroporous adsorption resin;the dynamic adsorption and separation were used in studying the condition of adsorption and separation.The total flavone adsorption capacity,total flavone content,and total flavone recovery rate were used as the evaluation criteria.The UV spectrophotometric method was used in the determination of total flavone content.Results The results showed that among 11 types of macroporous adsorption resins,the HPD400 was the best for adsorbing and separating the total flavone in S.glabra in the following technological condition: the concentration of S.glabra sample extract was 10 mg/mL;the maximum adsorbing capacity for total flavone in S.glabra was 9.5 mg/mL;the current velocity was 2.5 mL/min;the eluting reagent was 70% ethanol(three times as the volume of the resin);and the HPD400 resin could be used three times,repeatedly.Conclusion It is a simple and efficient to separate the total flavone in S.glabra under the technological conditions,and a total flavone recovery rate is about 85%.

Objective To explore the regulating mechanism of inducible nitric oxide synthase(iNOS) in hepatic injury of obstructive jaundice (OJ) in vivo and in vitro experiments. Methods (1) Rat hepatocytes were isolated by in situ collagenase perfusion and primary culture. Hepatocytes were pretreated with various concentrations of iNOS inhibitor SMT for 20 min. After pretreatment, 50?M GCDC was added for an additional 24hr. Cells were next detected by FCM and TUNEL.(2) Experimental obstructive jaundice (BDL) was induced by double ligation of the bile duct in rats. After BDL for 3d、7d、14d、and 21d, the apoptotic status in liver of all rats were determined with TUNEL, and iNOS protein in liver of OJ was ditermined with immunohistochemistry method. Results (1) SMT decreased GCDC-induced apoptosis in a concentration-dependent manner. (2) The apoptotic rate of liver was related to length of time of OJ. Apoptosis index (AI) was highest from rats with 14d bile duct ligation. The stronger the iNOS expression, the higher was the number of apoptotic cells that was found in OJ. Conclusions iNOS is involved in the regulation and the occurrence and progression of hepatic injury of obstructive jaundice.

With dwindling number of new antibiotics and inappropriate use of antibiotics, the emergence and spread of antibiotics resistance occurs commonly in healthcare institutions worldwide. In China, antibiotics are commonly overprescribed and misused. This study is to assess the effect of the nationwide special campaign on antibiotic stewardship program (ASP) at specialized hospitals in China by investigating prescription information from 2011 to 2012. Data on the hospital consumption and prescription of systemic antibiotics were obtained from four specialized hospitals, including maternity, children's, stomatological and cancer hospitals. Systematic random sampling was used to select outpatient prescriptions and inpatient cases. A total of 105 specialized hospitals in 2011 and 121 specialized hospitals in 2012 were analysed. The defined daily doses (DDDs) per 100 inpatient days, the percentage of antibiotic use in outpatient prescriptions, and the percentage of antibiotic use in inpatient cases were used as measurements of antibiotic use. The overall antibiotic use density in the selected hospitals decreased between 2011 and 2012 from 39.37 to 26.54 DDD/100 inpatient days (P<0.001). The percentage of antibiotic use in outpatient prescriptions (range: 24.12%-18.71%, P=0.109) and inpatient cases (64.85%-60.10%, P=0.006) also decreased within the two years. Significant changes were observed among regions and different hospitals within the two years. And antibiotic consumption was correlated with the type and size of specialized hospital in 2012, but not with the regions. This analysis of antibiotic consumption of specialized hospitals allows relevant comparisons for benchmarking and shows that national ASP has improved antibiotic rational use in China. The data will assist policymakers in formulating effective strategies to decrease antibiotic overuse and identify areas that require further work.

OBJECTIVETo evaluate the effect and safety of Nuanxin Capsule (NXC) in treating patients with chronic heart failure (CHF).

METHODSAdopting the randomized, positive controlled, double-blinded design, 150 CHF patients were assigned to the treatment group and the control group equally, they were treated with optimal western medical therapeutic scheme in combining respectively with NXC and placebo for 24 weeks. The indices for effectiveness and safety evaluation, such as Chinese medicine syndrome, grade of heart function, myocardial contraction, as well as the re-hospitalization rate and mortality, were observed.

RESULTSThe total effective rate on heart function in the treatment group and the control group was 78.87% and 64.38% respectively, that on Chinese medicine syndrome was 85.9% and 63.0% respectively, comparisons of the two indices between the two groups all showed significant difference (P < 0.05, P < 0.01). And a better efficacy for improving patients' cardiac contraction function and quality of life was shown in the treatment group (P < 0.05, P < 0.01). The re-hospitalization rates in them were 23.9% and 53.4% respectively (P < 0.05), and 22.54% and 42.5% of the re-hospitalized patients had attack of acute heart failure, a significant difference was found between the two groups (P < 0.05). The mortality in them was 2.90% and 8.95% respectively, showing no significant difference between groups (P > 0.05). No obvious adverse effect was found in both groups.

CONCLUSIONSNXC could improve the heart function of patients, it has obvious curative effect and good safety in treating chronic heart failure.
