METHODS:Three hundred and thirteen HC patients admitted to the Eastern Hepatobiliary Surgery Hospital(Shanghai,China) in 2000-2005 and 608 healthy controls were enrolled in this study.Association between HC and pre-existing medical conditions was studied with their adjusted odds ratio(OR) calculated by logistic regression analysis. RESULTS:The prevalence of choledocholithiasis(adjusted OR=2.704,P=0.039) ,hepatolithiasis(adjusted OR=3.278,P=0.018) ,cholecystolithiasis(adjusted OR =4.499,P<0.0001) ,cholecystectomy(adjusted OR =7.012,P=0.004) ,biliary ascariasis(adjusted OR= 7.188,P=0.001) ,liver fluke(adjusted OR=10.088,P =0.042) and liver schistosomiasis(adjusted OR=9.913,P=0.001) was higher in HC patients than in healthy controls. CONCLUSION:Biliary tract stone disease(choledocho-lithiasis,hepatolithiasis,cholecystolithiasis) and parasitic liver disease(biliary ascariasis,liver fluke,liver schistosomiasis) are the risk factors for HC in Chinese population.展开更多

A completely randomexperimental design with three replications was employed, having four soil management practices astreatments, namely: an undisturbed plow layer (CK), a thin plastic film (TN), a thick plastic film(TI) and subsoil compacting (CP). Results indicated no significant differences among all treatmentsfor rice biomass and grain yields. Also, water consumption was about the same for treatments TN andCK, however the treatments TI and CP were much lower with more than 45% and 40% of the irrigationwater in the treatments TI and CP, respectively, saved each year compared to CK. Therefore, wateruse efficiency was higher in the treatments TI and CP. These results will provide a scientific basisfor the water-saving rice cultivation.展开更多

Sustainability is found to be related with GDP in two contradic- tory ways. On the one hand, growth in GDP strengthens a nation’s ability to maintain favorable environmental conditions into the future. On the other hand, GDP growth is built on more consump- tion of natural resources, and therefore generates a larger “foot- print” on the Earth. Governance plays a key role in sustainable development. However, it is not helping to reduce our footprint on the Earth. In fact, good governance is linked to a larger footprint. This reflects our materialist value and human impulse. When a society prefers the comfort and well-being of human beings to the welfare of its environment, democratic governance might be used as an effective tool against nature.展开更多
