Objective:To explore the consistency of peripheral whole blood and venous serum procalcitonin (PCT) levels, and the value of peripheral whole blood PCT in evaluating pediatric bacterial infection.Methods:This multicenter cross-sectional parallel control study was conducted in 11 children′s hospital. All the 1 898 patients older than 28 days admitted to these hospitals from March 2018 to February 2019 had their peripheral whole blood and venous serum PCT detected simultaneously with unified equipment, reagent and method. According to the venous serum PCT level, the patients were stratified to subgroups. Analysis of variance and chi-square test were used to compare the demographic characteristics among groups. And the correlation between the peripheral blood and venous serum PCT level was investigated by quantitative Pearson correlation analysis.The PCT resultes were also converted into ranked data to further test the consistency between the two sampling methods by Spearman′s rank correlation test. Furthermore, the ranked data were converted into binary data to evaluate the consistency and investigate the best cut-off of peripheral blood PCT level in predicting bacterial infection.Results:A total of 1 898 valid samples were included (1 098 males, 800 females),age 27.4(12.2,56.7) months. There was a good correlation between PCT values of peripheral whole blood and venous serum ( r=0.97 , P<0.01). The linear regression equation was PCT?venous serum=0.135+0.929×PCT peripheral whole blood. However, when stratified to 5 levels, PCT results showed diverse and unsatisfied consistency between the two sampling methods ( r=0.51-0.92, all P<0.01). But after PCT was converted to ordinal categorical variables, the stratified analysis showed that the coincidence rate of the measured values by the two sampling methods in each boundary area was 84.9%-97.1%. The dichotomous variables also showed a good consistency (coincidence rate 96.8%-99.3%, Youden index 0.82-0.89). According to the severity of disease, the serum PCT value was classified into 4 intervals（<0.5、0.5-<2.0、2.0-<10.0、≥10.0 μg/L）, and the peripheral blood PCT value also showed a good predictive value (AUC value was 0.991 2-0.997 9). The optimal cut points of peripheral whole blood PCT value 0.5、1.0、2.0、10.0 μg/L corresponding to venous serum PCT values were 0.395, 0.595, 1.175 and 3.545 μg/L, respectively. Conclusions:There is a good correlation between peripheral whole blood PCT value and the venous serum PCT value, which means that the peripheral whole blood PCT could facilitate the identification of infection and clinical severity. Besides, the sampling of peripheral whole blood is simple and easy to repeat.

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.

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.

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.

OBJECTIVETo investigate the cause and related risk factors of an outbreak caused by Brucellosis.

METHODSEpidemiological investigation and laboratory test were carried out among occupationally invloved population including sheep slaughters and sellers in the village.

RESULTS18 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.

CONCLUSIONThe 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.
