Study on related factors of colorectal polyps / 上海预防医学

[ Objective ] To explore the related factors of colorectal polyps. [ Methods ] Participants were divided into polyps group and control group according to colonoscopy.The possible risk factors were investigated by questionnaire.Logistic regression analysis was conducted in order to explore the related factors of colorectal polyps. [ Results] A total of 252 participants (154 in polyps group, 98 in control group) were enrolled in the current study.Multivariate Logistic regression analysis showed that those with higher odds ratio of colorectal polyps were among male ( OR: 2.65, 95% CI: 1.17 -6.00) and obesity(OR:4.80,95%CI:1.16 -9.94), among those with family history of colorectal polyps ( OR:10.19, 95%CI:1.19-17.26), and those with high proportion of fat intake(OR:3.24, 95%CI:1.46-7.20). [ Conclusion] Male, obesity, family history of colorectal polyps and high proportion of fat intake are the related factors of colorectal polyps. And investigation by related factors questionnaire facilitates the targeted screening of colorectal tumors.

Correlation between PiCCO and ThDCO in monitoring perioperative hemodynamics in patients undergoing orthotopic liver transplantation / 上海第二医科大学学报

Objective To explore the correlation between the two methods of pulmonary arterial thermodilution technique(ThDCO)and pulse indicator continuous cardiac output(PiCCO)in determining hemodynamic changes in patients undergoing orthotopic liver transplantation(OLT).Methods Eighteen patients with end-stage liver disease(ASAⅡ-IV)were performed OLT and monitored hemodynamic changes by PiCCO method and ThDCO method simultaneously.The hemodynamic parameters including mean arterial pressure(MAP),cardiac output(CO)and systemic vascular resistance(SVR)were measured at different time points before anesthesia induction,after tracheal intubation,after the beginning of operation,at anhepatic phase,at neohepatic phase,at the end of operation,and after operation.Results Good correlation was found between the two methods for the determination of CO and SVR(r=0.987,P0.05).Conclusion The hemodynamics change dramatically in patients undergoing OLT.There is good correlation between the two methods of PiCCO and ThDCO for perioperative hemodynamic monitoring in patients undergone OLT,and PiCCO detection can be used conveniently for real-time continuous monitoring.
