Objective To investigate the effects of methylprednisolone on severe bronchial asthma treatment and intervention effect. Methods According to the different treatment methods will be January 2016 to March 2017 year in our hospital 90 cases of patients with severe bronchial asthma were selected,and randomly divided into observation group and control group,45 cases in each groups.The control group with conventional treatment method, the observation group used conventional methylprednisolone therapy; two the experimental results were recorded in detail, and the relevant data for comparative analysis, investigate the effects of methylprednisolone in treatment of severe bronchial asthma and intervention effect. Results The observation group (conventional methyl prednisolone) clinical treatment effect is better than that in control group (conventional) clinical efficacy, clinical symptoms disappeared. Time and so on were better than the control group, the adverse reaction rate were lower than the control group, there were significant differences between the groups (P<0.05) .Conclusion Severe bronchial asthma patients choose conventional methylprednisolone treatment significantly, in a short period of time can effectively improve the clinical symptoms and the adverse reaction is less, it is widely used in clinical treatment of severe bronchial asthma patients.

Objective To promote the diagnostic accuracy of intrapancreatic accessory spleen (IPAS).Methods The clinical data of 10 cases of IPAS admitted in Fudan University Zhongshan Hospital from Apr 2005 to Dec 2013 were retrospectively analyzed.Results There were ten cases of IPAS confirmed pathologically.Only 1 of the ten cases was diagnosed correctly and definitely with IPAS preoperatively.The other 9 cases were misdiagnosed with benign or malignant pancreatic tumors,including nonfunctional neuroendocrine neoplasms in 5 cases,pancreatic neuroendocrine cancers in 3 and pancreatic intraductal adenocarcinoma in one.All the nine misdiagnosed patients has no specific symptoms or laboratory indexes.All the IPASs located in the tail of the pancreas with the mean diameter (1.3 ±0.2) cm(0.8-2.5 cm).7 cases of IPAS show strikingly similar dynamic enhancement to the spleen on the CT scans and/or MRI.Accessory spleen around the splenic hilum was found in five cases.Conclusions Morphological study plays an important role in the diagnosis and IPAS carries parallel dynamic enhancement to the spleen on CT scans and/or MRI.IPAS should be considered as a differential diagnosis while the lesion is no more than 2.5 cm in diameter and when other accessory spleens were shown around the splenic hilum.

Objective To compare the short-term efficacy of pylorus-preserving pancreaticoduodenectomy (PPPD) and standard pancreaticoduodenectomy (SPD) for the treatment of periampullary carcinoma.Methods The clinical data of 85 patients with periampullary carcinoma who were admitted to the Zhongshan Hospital of Fudan University from October 2010 to October 2012 were retrospectively analyzed.Forty-four patients who underwent PPPD were divided into the PPPD group and 41 patients who underwent SPD were divided into the SPD group.The pancreatic fistula(Grade B and above), biliary fistula, blood loss, intra-abdominal infection, delayed gastric emptying (DGE) and prognosis were analyzed.Patients were followed up by telephone interview and outpatient examination once every 3 months within postoperative 1 year and once every 6 months within postoperative 2-3 years till October 2014.Count data were analyzed using the chi-square test, measurement data with normal distribution were presented as M(Qn) and comparison was analyzed using the Mann-Whitney U test.The survival curve was drawn by the Kaplan-Meier method, and survival rate was analyzed using the Log rank test.Results The operation time was 195 minutes (180 minutes, 240 minutes) in the PPPD group and 210 minutes (180 minutes,300 minutes) in the SPD group, with a significant difference (Z =-2.090, P ＜ 0.05).The volume of intraoperative blood loss, intraoperative blood transfusion and duration of postoperative hospital stay were 200 mL(113 mL,288 mL), 0 mL(0 mL, 0 mL) and 17 days(12 days, 24 days) in the PPPD group, and 200 mL(150 mL, 325 mL),0 mL(0 mL, 400 mL) and 16 days(12 days, 30 days) in the SPD group respectively, with no significant differences between the 2 groups (Z =-1.185,-1.780,-0.533, P ＞0.05).There was no perioperative death and incidence of overall complication was 42.4％ (36/85) with pancreatic fistula, intra-abdominal infection and DGE as the top 3 common postoperative complications.The incidence of DGE was 20.5％ (9/44) in the PPPD group,which was significantly different from 4.9％ (2/41) in the SPD group (x2=4.571, P ＜ 0.05).The incidence of pancreatic fistula, biliary fistula, intra-abdominal infection, postoperative bleeding and 2 or more complications were 20.5 ％ (9/44), 2.3 ％ (1/44), 15.9％ (7/44), 4.5 ％ (2/44), 25.0％ (11/44) in the PPPD group, and 14.6％ (6/41), 4.9％ (2/41), 19.5％ (8/41), 7.3％ (3/41), 14.6％ (6/41) in the SPD group, respectively, showing no significant difference between the 2 groups (x2=0.495, 0.423, 0.295, 0.190, 1.425, P ＞ 0.05).Eighty-five patients were followed up for 6-47 months with a median time of 31 months, and postoperative overall 1-and 3-year survival rates were 95.3％ and 75.5％, respectively.The 1-and 3-year survival rates were 97.7％ and 78.9％ in the PPPD group, and 92.7％ and 71.7％ in the SPD group, respectively, with no significant difference in 3-year survival rate (x2=0.690, P ＞0.05).The 3-year overall survival rate was 80.5％ in patients without lymph node involvement (LNI) compared with 54.9％ in patients with LNI, showing a significant difference (x2=4.290, P ＜ 0.05).Conclusions Both PPPD and SPD have good short-term efficacy for periampullary carcinoma.There is no significant difference between PPPD and SPD concerning short-term survival rate of periampullary carcinoma.PPPD has shorter operation time, but has a higher postoperative DGE incidence.LNI is a significant prognostic factor for short-term survival of periampullary carcinoma.PPPD is not recommended while the lymph nodes are involved.

Objective To investigate the risk factors of delayed gastric emptying after pancreaticoduodenectomy (PD) for periampullary carcinoma.Methods The clinical data of 96 periampullary carcinoma patients who received PD with or without pylorus preservation at Zhongshan Hospital Fudan University from October 2010 to September 2013 were retrospectively analyzed.The risk factors associated with delayed gastric emptying were analyzed.The univariate and multivariate analysis were done using the chi-square test and Logistic regression model respectively.Results A total of 17 patients had postoperative delayed gastric emptying, with the incidence of 18％.The results of univariate showed that female sex, pancreatogastrostomy, increased intraoperative blood loss and transfusions and postoperative abdominal infection were risk factors of delayed gastric emptying (x2 =4.512, 6.412, 6.245, 6.695, 6.816, all P ＜ 0.05).The results of multivariate analysis revealed that only pancreatogastrostomy and postoperative abdominal infection were independent risk factors of delayed gastric emptying (OR =4.031 and 5.281).Conclusions Pancreatogastrostomy and postoperative abdominal infection indicate a higher incidence of delayed gastric emptying after pancreaticodudenectomy for periampullary carcinoma.

Objective To evaluate the effect of virtual reality on motor function in patients with stroke. Methods PubMed, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure (CNKI), VIP Database for Chinese Technical Periodicals and Wanfang Data were searched for the randomized controlled trials (RCTs) of virtual reality on motor function in patients with stroke from the date of establishment to January 2013. The included studies were evaluated according to the method recommended by the Cochrane Collaboration. RevMan 5.0 software was used to analyze the extracted data. Results 20 trials were included (13 trials about the upper extremity function and 7 trials about the lower extremity function). Compared with conventional training, the virtual reality training significantly increased the score of Fugl-Meyer assessment (FMA) (WMD=4.27, 95%CI: 2.47~6.06, Z=4.67, P<0.00001) and Box and Block Test (BBT) (WMD=9.29, 95% CI: 5.24~13.34, Z=4.50, P<0.00001). However, the results of Berg balance scale (BBS) (WMD=1.63, 95% CI: -0.83~4.09, Z=1.30, P=0.20) and walking speed (WMD=0.01, 95%CI: -0.14~0.17, Z=0.18, P=0.86) were not statistically significance for the lower extremity function. According to the Jadad Score of included studies, 16 of them were of low quality and only 4 of them were of high quality. Conclusion The virtual reality training could improve the upper extremity function in patients with stroke, but not for the lower extremity function.

Objective To investigate the cause and related risk factors of an outbreak caused by Brucellosis. Methods Epidemiological investigation and laboratory test were carried out among occupationally invloved population including sheep slaughters and sellers in the village. Results 18 people were serology positive among the 129 occupationally involved persons under survey. Seven of them were confirmed cases,11 were latent infection,to make the overall attack rate as 14%. 90%of the sheep were from high-risk areas of Brucella. Among the occupationally involved persons,89%of them never wore face masks,84%never wear overalls and 70%never wear gloves. Factors as:work but wearing no gloves(RR=7.4,95%CI:1.1-53.0),with hand wound(RR=3.4,95%CI:1.1-11.0) could increase the risk of Brucella infection. Conclusion The cause of this outbreak was due to the plentiful influx of unchecked sheep from the northern part of China and the employees in the process of sheep slaughtering or trading were lack of effective prevention programs.

OBJECTIVETo investigate the hepatitis C virus (HCV) infection rate among general population in Jiangsu province and to analyze the main risk factors for HCV infection.

METHODSSubjects in 3 counties were surveyed by stratified cluster random sampling in the National Major Science and Technology Projects demonstration area in Jiangsu province. Interview was carried out with uniformly- designed questionnaires. Blood samples were collected and anti-HCV tested. Data were analysed under SPSS 13.0. Case-control study was conducted on two groups with subjects under 1:4 matching by sex, age, village of residence and status of HCV infection. Cox's proportional hazards regression analysis was then performed to analyze the risk factors for HCV infection.

RESULTSThe positive rate of anti-HCV was higher in females (0.965%, 95%CI:0.899%-1.035%) than in males (0.572%, 95%CI:0.517%-0.632%). Significant differences were noticed among the positive rates of anti-HCV in the three counties (0.131%, 95%CI:0.103%-0.164%;0.316%, 95%CI: 0.268%-0.370%; 2.173% , 95% CI:2.039%-2.315% , respectively). Peak prevalence of anti-HCV (1.577%, 95%CI:1.425%-1.740%) was observed among persons at 50-59 years of age. Bottom rate (0.161%, 95%CI:0.125%-0.204%) was observed below 30 years of age. High anti-HCV positive rate was detected in people with lower education background or belonged to 'floating population'. Factors as having histories of hospitalization (OR = 3.049, 95% CI:1.322-7.036), blood transfusion (OR = 14.319, 95%CI:2.318-88.459) or sharing razor (OR = 3.604, 95%CI:1.096-11.851) were risk factors of HCV infection in the area with the lowest anti-HCV positive rate. In another county, factor as having histories of 'blood products transfusion' (OR = 7.202, 95% CI:1.170-44.310) appeared important while in the third county, having history of 'blood donation' (OR = 7.496, 95%CI:6.121- 9.180); 'blood transfusion' (OR = 2.305, 95%CI:1.578-3.369) and 'invasive physical examination' (OR = 1.258, 95% CI:1.021-1.549) appeared to be important. Age seemed a risk factor for HCV infection. "Sharing razor" was a specifically important risk factor among the 30- year-olds. "Having received acupuncture" was noticed a risk factor only among people at 50-59 years of age while "Having received invasive physical examination" was important in the 50-59 and 60-69 year-olds.

CONCLUSIONHigh anti-HCV positive rate was observed in people at middle of aged population, as well as in those with poor education or under 'floating'. Unsafe blood donation or having received blood-product transfusion might be the risk factors in the last decades. Factors as sharing razor, having received acupuncture or invasive examination might be specifically risky in different populations.

OBJECTIVETo assess the antibiotic resistance and molecular characterization of cholera strains and to provide basis for clinical treatment and prevention of cholera.

METHODS4 stains isolated from an outbreak of cholera epidemic in Huai'an City in Jiangsu province in September 2010 were characterized using antibiotic susceptibility, biotype analysis, virluence genes detection, ctxB gene sequencing, and PFGE analysis.

RESULTSThe 4 strains were all resistant to sulphamethoxazole/trimethoprim, erythromycin, streptomycin. High drug susceptibility of the samples was found to 6 kinds of antibiotics such as amikacin, norfloxacin, ciprofloxacin, gentamicin, chloramphenicol, ampicillin. The isolates expressed phenotypic traits of both serogroup O1 ogawa and El Tor and carried 9 kinds of virulence genes, ctxA, ace, zot, toxR, tcpI, ompU, rtxC, tcpA, and hlyA gene. They were also identified as harboring the classical ctxB genotype based on amino acid residue substitutions. The PFGE profiles of NotI showed a single banding pattern, while SfiI's was 2 banding patterns.

CONCLUSIONThe bacterium type of Vibrio cholerae causing the epidemic outbreak of cholera belonged to the atypical EL Tor variant which was also identified as toxicogenic strain. The mapping of the strains prompted that there should be the common contamination source. Drug sensitivity test can guide the clinical drug use, in order to reduce the emergence of resistant strains.
