Objective To detect the effect of the operative and non-operative therapy on acute mesenteric venous thrombosis (AMVT).Methods The documents of 18 AMVT patients from Jan 1990 to May 2006 were reviewed retrospectively.Results In 18 patients, 12 cases with intestinal necrosis received operation, among them, 2 cases received the operation only and 10 cases added with anti-coagulation therapy further. The rest 6 patients received non-operative therapy. All of 18 patients recovered well.Conclusion Non-operative therapy is safe and effective for the patients without intestinal necrosis. Post-operative anti-coagulation therapy is very important for the patients received the operative therapy.

Objective To investigate the pediatric intensive care unit (PICU) in critically ill children with pediatric critical score (PCIS) and pediatric death risk score (PRISM),comparing its value.Methods A total of 100 cases of matching children with acute respiratory distress syndrome (ARDS) to stay in our hospital during 2007.07 ～2012.07 was retrospectively analyzed.Check PICU most serious disease in this group of children,living PICU most severely ill when diagnosed with acute respiratory distress syndrome (ARDS),when it was suffering from ARDS most serious line PCIS with PRISM score,and then using the Logistic multiple regression to analyze the scores of the two scoring ability as predicting the ARDS death in children with risk factors,and using two-factor analysis of variance of the two scoring methods by judging linear correlation existence.Results (1)PCIS with PRISM score showed a negative correlation (r=-0.6031,P ＜0.01),the linear regression equation y =-0.2389x +74.816 (P＜0.01).(2) There was no statistical difference between the ARDS death group and survival group (P ＞ 0.05) ; By PCIS PRISM score LOGISTIC regression analysis of the risk of death in children,there was no statistical difference (P ＞ 0.05).Conclusions PCIS and PRISM score cannot be the standards to forecast the death of the ARDS patients,but can provide an objective referring standard of ARDS's treatment.

Objective To assess the application value of REP-PCR in genotyping of candida glabrata strains in clinical pratice. MethodsFrom 2009 to 2010, thirty-eight candida glabrata strains were isolated from Shanghai Ruijin Hospitals, Shanghai Renji Hospital, Shanghai Huashan Hospital, Anhui Medical University Hospital, Shenzhen People's Hospital. Six loci in housekeeping genes (FKS, LEU2,NMT1, TRP1, UGP1 and URA3 ) were amplified and sequenced. The sequences were compared with the MIST database and allele profile and sequence type (ST) were obtained. With primers Ca21, Ca22 and Com21 used to amplify the adjacent variable gene regions,the amplicons were analyzed through electrophoresis to generate different REP-PCR types. Finally, the results of these two genotyping methods were compared. ResultsFor REP-PCR, Ca22-Com21 has the best genotyping effect. REP-PCR and MLST have the same genotyping results. Five REP-PCR types were found in 38 candida glabrsta isolates. Type A,B, C, D and E strains from REP-PCR were genotyped as ST 7, 3, 19, 45 and new type respectively byMIST. REP-PCR saves time compared with MIST. Conclusions REP-PCR offers a simple and rapid method for molecular typing, with similar discriminatory power with MIST. Therefore, REP-PCR can be the preferred choice in laboratory, especially for a large number of isolates.

Objective To investigate the mechanisms of fluconazole resistance in clinical and experimental induced isolates of C.glabrata.Methods Efflux of rhodamine 6G was performed to evaluate the effects of efflux pumps.The expression levels of transporter genes CDR1,CDR2,SNQ2 and ERG11 were examined by real-time RT-PCR.Meanwhile,sequence of PDR1 was determined by PCR based DNA sequencing.Results Efflux pumps of all fluconazole-resistant isolates had stronger effects than that of susceptible isolates,consistently with significant upregulation of CDR1,but no obvious difference was found in CDR2 or SNQ2.Also,no notable change in the expression level of ERG11 between susceptible and resistant isolates.PDR1 mutations existed in both clinical and experimental induced isolates of C.glabrata,among which P927S,L543P and S947L haven't been reported previously.Conclusion Mutations of PDR1 were induced by fluconazole both in vivo andin vitro,which will result in overexpression of CDR1 and strengthen the effect of efflux pump.

Objective To analyze the risk factors of central compartment lymph node (CCLN)metastasis in papillary thyroid carcinoma(PTC) without clinically suspected cervical lymph node metastasis (cN0).Methods Clinical data of 272 PTC (cN0) patients who underwent radical thyroidectomy and CCLN dissection between January 2008 and December 2012 in Huashan hospital were retrospectively analyzed.Patients were divided into CCLN positive group (115 cases)and CCLN negative group(157 cases) according to postoperative pathology.Chi-square test,wilcoxon test and multivariate logistic regression analysis were used to analyze risk factors.Results CCLN metastasis of papillary micro thyroid cancer (PMTC) and papillary thyroid cancer (PTC) was 34.9％ and 48.3％,respectively.Tumor size (x2 =10.26,P ＜ 0.01),position(x2 =13.87,P ＜ 0.01),capsular invasion(x2 =20.19,P ＜ 0.01),multifocal PTC(x2 =7.42,P ＜ 0.01) and unmicro-carcinoma (x2 =5.12,P ＜ 0.05) were significantly correlated to lymph node metastasis.Middle area or lower pole of thyroid carcinoma,capsular invasion and multifocal PTC were independent risk factors of CCLN metastasis in PTC.Conclusions The cN0 PTC has a high rate of pathological CCLN metastasis,it is imperative to conduct thyroidectomy with ipsilateral level CCLN dissection in PTC patients.

AIM To compare the effects of micronised fenofibrate with those of standard fenofibrate on regulating serum lipid. METHODS Wistar rats were fed by the hyperlipids food to induce hypolipidemia, and then orally treated with 20,30,40 mg?kg -1 per day micronised fenofibrate and 20,30,40,60,80 mg?kg -1 per day standard fenofibrate for 10 days. At the tenth day, serum total cholesterol and triglycerides were measured. RESULTS 1 In the same experimental conditions,the minimal efficacious dose of the micronised fenofibrate is 30 mg?kg -1 , but that of the standard fenofibrate is 80 mg?kg -1 ; 2 Using efficacious doses, both kinds of fenofibrate could decrease the content of triglyceride to normal level. They also could decrease the level of total cholesterol by 36 69%～51 56%. CONCLUSION The effects of micronised fenofibrate are better than those of standard fenofibrate, which mainly decreases the level of triglyceride. Micronised fenofibrate also decreases level of serum total cholesterol.
