RESUMEN
Precision medicine became the key strategy in development priority of science and technology in China.The large population-based cohorts become valuable resources in preventing and treating major diseases in the population,which can contribute scientific evidence for personalized treatment and precise prevention.The fundamental question of the achievements above,therefore,is how to construct a large population-based cohort in a standardized way.The Chinese Preventive Medicine Association co-ordinated experienced researchers from Peking University and other well-known institutes to write up two group standards Technical specification of data processing for large population-based cohort study (T/CPMA 001-2018) and Technical specification of data security for large population-based cohort study (T/CPMA 002-2018),on data management.The standards are drafted with principles of emphasizing their scientific,normative,feasible,and generalizable nature.In these two standards,the key principles are proposed,and technical specifications are recommended in data standardization,cleansing,quality control,data integration,data privacy protection,and database security and stability management in large cohort studies.The standards aim to guide the large population-based cohorts that have been or intended to be established in China,including national cohorts,regional population cohorts,and special population cohorts,hence,to improve domestic scientific research level and the international influence,and to support decision-making and practice of disease prevention and control.

RESUMEN
Objective To explore the correlated risk factors of bile duct injury induced by laparoscopic cholecystectomy ,and to reduce the rate of bile duct injury companied with LC and improved patients condition after LC .Methods One thousand two hun‐dred and forty four patients who had been done the laparoscopic cholecystectomy in our hospital were searched from December 2003 to December 2013 for their case notes .The relationship between rate of bile duct injury induced by laparoscopic cholecystectomy and gender ,age ,time of LC surgery ,pathology ,gallbladder wall thickness ,liver function levels ,the existence of the gallbladder triangle anatomical anomalies and physician experience were analyzed by logistic regression method .Results Logistic regression analysis showed that patients did LC surgery at early time ,with acute cholecystitis ,with gallstones combined effusion ,with gallbladder wall thicker than 4 mm and with gallbladder triangle anatomical anomalies were likely to have bile duct injury induced by LC (P<0 .05) .And doctor′s experience on LC is another important factor as well (P<0 .05) .Conclusion According to the correlated risk factors of bile duct injury caused by laparoscopic cholecystectomy ,methods should be employed to reduce the bile duct injury .And sharing experience between doctors and learning new techniques could be helpful ,too .
