Objective To explore the effect of health check-up on screening and early detection of colorectal or breast cancer.Methods A total of 4 179 health check-up receivers were enrolled in this investigation.Basic health information was linked to the Shanghai Cancer Registry System and confirmed cancer diagnosis through Access 2007.Excel 2013 was used to analyze cancer detection rate,ranking,age and sex distribution and early stage proportion.Results During 2011 and 2012,81 cancer cases were identified,with a detection rate of 47.47/100 000.The highest detection rate was found in 60-69 years old group (105.36/100 000),and male:female ratio was 1.25 ∶ 1.One colorectal cancer was diagnosed,resulting in a detection rate of 0.79/100 000.Eleven breast cancers were diagnosed,with a detection rate of 17.22/100 000.Early stage breast cancer accounted for 71％,which was higher than average level between 2005-2009 (33％).Conclusion Detection rate of colorectal cancer among health check-up receivers was very low,which is inconsistent with the high incidence of colorectal cancer in Shanghai.Fecal occult-blood test should be performed during health check-up,which may increase colorectal cancer detection.Moreover,health check-up may contribute to early detection of breast cancer.

Objective To evaluate the short-term prediction of high-sensitivity cardiac troponin T (hs-cTnT) and other cardiovascular risk biomarkers in patients undergoing maintenance hemodialysis (MHD).Methods We conducted a cohort survey in 296 consecutive MHD patients whose clinical data were retrospectively analyzed.Before MHD,hs-cTnT and other relative cardiovascular biomarkers were detected.The end point (all-cause death) and time of occurring were recorded in the next 13 months.The differences between survival and all-cause death were analyzed by t-test,Mann-Whitney test and x2 test.The best two percentile cutoff point was calculated by X-tile and the survival rate was calculated by Kaplan-Meier Logistic regression analysis was applied to analyze the odd ratio between high risk and non-high risk hs-cTnT group.Non-high risk group was divided into intermediate risk and low risk group based on the 99th percentile of hs-cTnT in healthy population,to further evaluate its short-term prediction value for MHD patients.The short-term significance of hs-cTnT was proved to be independently associated with all-cause death by Logistic regression analysis.Results The mean value of serum hs-cTnT in survival group was 0.05 (0.03～0.07) ng/mL,while in the death group it was 0.07 (0.04～0.14) ng/mL,which had statistical significance (P =0.027).The best two percentile cutoff of hs-cTnT in MHD patients was 0.1 ng/mL.The survival rate in high risk group (hs-cTnT＞0.1 ng/mL) is lower than it in non-high risk group (hs-cTnT≤0.1 ng/mL) (76.67％ vs.96.62％,P ＜0.05).The odd ratios for high risk group and non-high risk group was 7.288 (P＜ 0.001).Moreover,further grouping the non-high risk group by hs-cTnT =0.014 ng/mL,intermediate risk group (hs-cTnT＞0.014 ng/mL) group has lower survival rate than low risk group (hs-cTnT≤0.014ng/mL),while there wasn't any death case occurred in the low risk group.Conclusions Hs-cTnT is an independent risk factor to all-cause death.Thus hs-cTnT can be a strong indicator of short-term prediction and prognostic evaluation.
