Objective To evaluate the prognostic value of MTV measured by pretreatment 18F-FDG PET/CT imaging in patients with pancreatic cancer (PC).Methods The clinical data of 52 patients (31 males,21 females,median age 58.5 years) with pathologically or clinically proved PC from January 2011 to October 2014 were retrospectively analyzed.Serum CA19-9 was measured within 1 week before PET/CT examination.SUVmax and MTV were measured respectively,and PET/CT staging was obtained simultaneously.All patients were followed up until January 2015.The CA19-9,MTV,SUVmax,PET/CT staging and clinical factors(age,gender,treatment methods) were assessed by ROC curve analysis,Kaplan-Meier analysis and multivariate Cox model.Results The median survival time of 52 patients was (11.20±7.25) months.ROC curve analysis showed that the AUC of MTV,SUVmax and CA19-9 were 0.735,0.614 and 0.527 respectively.Kaplan-Meier survival analysis manifested that the survival times were significantly different between patients with different MTV (＜ 12.14 cm3 vs ≥ 12.14 cm3),different SUVmax (＜ 8.95 vs ≥ 8.95),different PET/CT staging and different treatment methods (x2 =4.272-11.693,all P＜0.05).The survival time of patients with MTV ＜ 12.14 cm3 and that of patients with MTV ≥ 12.14 cm3 were (13.44±8.40) and (7.00± 4.82) months,respectively.Cox single-factor analyses indicated that MTV,PET/CT staging and SUVmax were risk factors of survival,the hazard ratios (HR) were 0.393,0.503,0.547 respectively (P=0.002,0.020,0.027).Cox multi-factor analyses indicated that MTV and PET/CT staging were independent risk predictors of survival.Conclusion MTV and PET/CT staging are significant factors in prognosis prediction of patients with PC,which would be helpful to make individual treatment for patients with high risks.

Objective To compare the performance of newly developed Chronic Kidney Disease Epideniology Collaboration (CKD-EPI) equation and Modification of Diet in Renal Disease (MDRD) equation in patients with peripheral arterial diseases (PAD).Methods A total of 841 patients with PAD were enrolled in this retrospective cohort study.Estimated glomerular filtration rate (eGFR), calculated by MDRD and CKD-EPI equation respectively, was analyzed by Spearman correlation analysis, Bland-Altman method and Kappa test for the evaluation of correlation and consistency.Net reclassification improvement (NRI) was adopted to compare the death risk assessment between these two equations.Results Although the eGFR was 4.33 ml· min-1 · (1.73 m2)-1 higher with MDRD equation than with CKD-EPI equation, there were still significant correlation and fine consistency between eGFRMDRD and eGFRCKD-EPI (Kappa: 0.749, r=0.991, P＜0.05).The CKD-EPI equation re-classified 9 (1.1％) patients upward to higher eGFR category and 143 (17.0％) patients downward to lower eGFR category.Besides, the performance of risk assessment for all-cause death was better with CKD-EPI equation than with MDRD equation (NRI=0.059, P ＜ 0.05), which was not the case for cardiovascular death (NRI=0.022, P ＞ 0.05).Conclusions There is no solid evidence suggesting that CKD-EPI equation performs better than MDRD equation.

Background:Faecalibacterium prausnitzii( Fp) is one of the most abundant bacterium in human intestinal microbiota,and is closely correlated with the process of colitis-associated colorectal cancer(CAC). Aims:To observe the effect of Fp on CAC,and investigate the possible mechanism. Methods:The model of CAC was induced by azoxymethane (AOM)and dextran sodium sulfate( DSS). Fifty-two C57BL/ 6J mice were randomly divided into 4 groups:group A (AOM + DSS),group B(AOM + DSS + Fp),group C(AOM + DSS + Fp supernatant)and group D(control group). All the mice were sacrificed on day 92. DAI was assessed,serum levels of TNF-α and IL-10 were determined by ELISA. HE staining was used to examine the grade of tumor. Expressions of VEGF,COX-2,NF-κB in tumor tissue were measured by immunohistochemistry. Results:The tumorigenesis rates of group A,B,C were 100% ,100% and 77. 8% ,respectively;mainly were high-grade intraepithelial neoplasia. The tumor load in group A was significantly higher than that in group B (P < 0. 01),and the spleen index in group B was significantly higher than that in group C(P < 0. 01). Serum level of TNF-α was significantly lower(P < 0. 05)and IL-10 was significantly higher(P < 0. 05)in group A than that in group B. No significant differences in expressions of VEGF,COX-2,NF-κB were found among group A,B and C. Conclusions:Fp had no obvious effect on the occurrence rate of CAC,and Fp supernatant could decrease the incidence of CAC in mice. Fp and its supernatant could reduce the tumor load via regulating the expressions of TNF-α,IL-10.
