Objective To investigate the safety,therapy and prophylactic effect of Omeprazole on stress ulcer in children with epidemic type B encephalitis.Methods Before and after medication,chest X-ray examination was performed.The result of occult blood(OB) was confirm by Colloidal gold assay in stool and/or gastric juice.Based on the result of OB,the patients were divided into therapy group[besides conventional therapy for encephalitis,Cimitidine group and Omeprazole group with positive result OB,was administered with 0.9% normal sodium 100 mL+Cimitidine 20-40 mg/(kg?d),iv,q12 h and normal sodium 100 mL+Omeprazol 0.5-0.8 mg/(kg?d),iv,qd,respectively] and prophylaxis group(Cimitidine group,Omeprazole group and control group,with negative result OB,were administered with same medicines as therapy group,respectively.Except control group being administered only 0.9%NS 100 mL,iv,(q12 h)).The effects of drugs on hemostasis,preventing hemorrhage,and the potential risk of acquired pneumonia result from drugs used were observed.Results In therapy group,the average time of hemostasis in Omeprazole group was obviously shorter than that of in Cimitidine group,there was significant difference between two groups(P0.05).Conclusions Both of the drugs is safety and effect to therapy or prophylaxis for the latent stress ulcer in short term.The effect of Omeprazole is better than those of Cimitidine.Using Cimitidine and Omeprazole,neither therapy nor prophylaxis for stress ulcer increaseds the potential risk of acquired pneumonia in children with epidemic type B encephalitis in this study.

Objective: To explore eye tracking movements of patients with depression.Methods:Thirty-one patients with depression were tested by tracking of exploratory eye movement (Type-Ⅳ) before and after treatment (mean interval 34?8 days), at the same time HAMD was applied. Thirty-one normal controls were tested by tracking of exploratory eye movement either.Results:There were significant differences of discriminant analysis between the results of patients and controls (0.52?1.58,0.79?1.44, vs.-1.00?0.85,t=4.40, 5.80, P0.05);Conclusion:There is statistical difference in exploratory eye tracking movements of depressive patients and that of controls. After depression improved, no significant changes were noted between the main indexes of eye tracking movements of the first test and that of the second test.

Irritable bowel syndrome(IBS) is a quite common disease,and it is a functional enteropathy that characterized by abdomen discomfort or pain,diarrhea,constipation or the mix of both.At present the clinical diagnosis refers to the Roman Ⅱ standard,but it is easy to create leaks examines.In 2006,the new Roman Ⅲ standard let clinician have a more objective basis regarding diagnosis of children with IBS.Its treatment is a complex therapy based on the symptom and serious degree of the symptom.The author will introduce children with IBS with emphasis on the diagnosis and treatment progress.

Objective To explore mechanism of action of rhubarb on intrahepatic cholestasis in infantile rats.Methods Ninety Sprague-Dawley(SD)infantile rats were randomly divided into 5 groups:treatment group of rhubarb,untreated group,treatment control group 1 of ursodeoxychlic acid(UDCA),treatment control group 2 of UDCA and deltasone,and control group not treated with ?-naphthyl isothiocyanate(ANIT)and any other treatments.Jaundice model of intrahepatic cholestasis was established in infantile rats by ANIT.At the time of the 2nd,3rd,and 4th week,the concentrations of serum total bilirubin(TB),direct bilirubin(DB),ALT,alkaline phosphatase(ALP),total bile acid(TBA)and TBA were assessed by automatic biochemical analyzer.The concentrations of nitrogen monoxide(NO),maleic dialdehyde(MDA)and the ability of total antioxidation(T-AOC)in liver tissues were measured.Results It was demonstrated that the animal model of hepatic jaundice with cholestasis was successfully established.The levels of serum DB,TB,ALP,ALT and TBA were significantly lower in the treatment group of rhubarb compared with those in the untreated group(Pa

University of Manchester who first introduced Problem based learning(PBL)to the UK medical education,and adopted this new curriculum in 1994.Notably,Cambridge and Oxford have always had a high proportion of student-centred and self-directed learning,and have therefore not introduced PBL.Other medical schools have followed the example of Manchester,now PBL has become the mainstream curriculum in British medical edacation.First,this article is going to introduce how PBL curriculum is structured at Manchester medical school,and then reflect and give some thoughts on its current practice.

Objective To investigate the distribution of pathogenic bacteria,drug sensitivity,and the relationship between drug sensitivity and Escherichia coli(E.coli) induced enzymes in childhood diarrhea in the last 2 years in Chongqing area,so as to provide important evidence for pediatric clinical therapy.Methods Thirty-one E.coli induced enzymes,extended spectrum ?-laetamases(ESBLs),cephalosporinase(AmpC)detected in different phenotype methods,and drug sensitivity was measured in paper strip method,and the specimens were collected from children′s hospital affiliated to chongqing university of medical sciences from Jan.2005 to Dec.2006 were determined.Among the total,there were 18 enteropathogeic E.coli(EPEC) strains,8 enterotoxigenic E.coli(ETEC) strains and 5 enteroinvasive E.coli(EIEC) strains.In addition,drug resistance tests by paper strip included chloramphenicol(CHL),amikacin(AMK),gentamicin(GEN),norfloxacin(NOF),ciproflocacin(CIP),cefazolin(CEZ),cefoperazone(CPZ),ceftriaxone(CRO),ceftazidime(CAZ),cefotacime(CTX),cefepime(FEP),imipenem(IPM).SPSS 12.0 software was used to analyze the data.Results Three point two percent of the 31 E.coli were drug resistant to IPM,and 35.5%,38.7% to NOF,CIP individually,but more than 60% to AMK,GEN,even more than 67.7% towards cephalosporin(except ceftazidime and cefepime);the gross enzyme-produced rate was 87.1%,rate of single ESBLs,AmpC,and induction of both enzymes simultaneously presented 64.5%,6.5%,16.1% respectively;and there was marked difference in drug resistance when bacteria that produced single AmpC versus bacteria that produced single ESBLs or that produced both ESBLs and AmpC(Pa﹤0.05).Conclusions The relationships among enzyme′s quantity,sort and bacterial resistance are different.These data show E.coli infected by bacterial diarrhea children in Chongqing due to a high rate of induced enzymes,and their drug resistance vary according to the state of induced enzymes.

Objective To evaluate the tolerance of preoperative neoadjuvant chemoradiotherapy (neoCRT) plus esophagectomy, as well as the short-term outcome, tumor resection rate, incidence of postoperative complications, and perioperative mortality, in patients with locally advanced esophageal cancer.Methods This study included 74 patients with thoracic esophageal cancer who were admitted to our hospital from May 2011 to June 2015.Chemotherapy and radiotherapy were performed concurrently.The chemotherapy consisted of vinorelbine (25 mg/m2 on days 1, 8, 22, and 29) and cisplatin (25 mg/m2 on days 1-4 and 22-25).The radiotherapy was conventionally fractionated with a total dose of 40 Gy (2.0 Gy/d).At 4-8 weeks after chemoradiotherapy, esophagectomy was performed (neoCRT+surgery group);definitive chemoradiotherapy (DCRT) was performed in the patients who refused surgery (DCRT group);follow-up was performed in the patients who refused any anti-cancer therapies after neoCRT (neoCRT group).Results Forty-four patients underwent neoCRT+surgery, with a radical resection (R0) rate of 100% and a pathological complete response (pCR) rate of 43%;17 patients received DCRT;13 patients received neoCRT alone.For the neoCRT+surgery group, DCRT group, and neoCRT group, the 2-year overall survival (OS) rates were 79%, 75%, and 17%, respectively, and the 2-year disease-free survival (DSF) rates were 75%, 55%, and 17%, respectively.There were significant differences in OS between the neoCRT group and the neoCRT+surgery group (P=0.000) and between the neoCRT group and the DCRT group (P=0.001), but no significant difference was observed between the neoCRT+surgery group and the DCRT group (P=0.415).There were significant differences in DFS between the neoCRT group and the neoCRT+surgery group (P=0.000) and between the neoCRT group and the DCRT group (P=0.002), but no significant difference was observed between the neoCRT+surgery group and the DCRT group (P=0.416).The rate of clinical response to preoperative neoCRT was 87% for all patients.Fifty-six patients (76%) developed grade ≥3 myelosuppression due to preoperative neoCRT.The incidence rates of postoperative pulmonary infection, anastomotic leakage, and anastomotic stenosis were 21%, 12%, and 7%, respectively, and the perioperative mortality rate was 2%.Conclusions For patients with locally advanced esophageal cancer, preoperative neoCRT plus surgery can increase the clinical response rate and pCR rate, reduce the tumor stage, and improve the survival, but chemoradiotherapy toxicities and perioperative complications cannot be ignored.

Obiective To study controUing method for curing time of the materials based on isocyanate, and perfect making means and operating rules of transmitting apparatus for the wounded, Methods According to the controlling principles of the rate of chemical reaction, the influencing factors' were studied such as catalyzer, ambient temperature, mixture level of materials and materials volume by experiment. Results By the results of experiments, ambient temperature hasn't an effector impact on eufing time of isocyanate, catalyzer and mixture level of materials only have a little effect or impact on initial reaction time, but materials volume is an important factor of all. Conclusion By the means of experiments, the curing time of isocyanate is only influenced by the volume of materials, and the character is very useful to transmitting apparatus for the wounded in field battle or on-site emergency rescue.

This study was to report the effect of Tangshen Formula on phospholipids metabolism in diabetic nephropathy patients. A normal phase-HPLC-TOF/MS method was used in this study for the determination of seven species of phospholipids in human plasma. Then, the concentration changes of potential phospholipids biomarkers were discussed in diabetic nephropathy phase III and phase IV patients among different groups, including before and 3, 6 months after administration of Tangshen Formula. Significant increases of PE750, PI885, PC792, PC826, PC830, PC854 and PC802 levels were observed 6 months after administration of Tangshen Formula and conventional western medicine, as well as a decrease of LPC540 level, when compared with those before medication. Concentrations of all the potential phospholipids biomarkers showed a tendency towards normal levels; however, both the improvement degree and onset time of these compounds were not same. Additionally, Tangshen Formula treatment based on conventional western medicine treatment was more efficient in adjusting the levels of these compounds when compared with western medicine treatment alone, especially for the phase IV patients. These results indicated that Tangshen Formula was capable in regulating and improving phospholipids metabolism in diabetic nephropathy patients, which may be related with the direct or indirect inhibition of protein kinase C pathway and the corresponding reduction of phospholipase A2 activity. Therefore, Tangshen Formula may be used as an effective drug for diabetic nephropathy therapy, at least as an adjunctive therapeutic drug.
