The result indicates that China's product-specific amber box support level has significantly increased but not yet exceeded the tolerable ceiling of de minimis and remains consistent with WTO rules on agricultural domestic support," that there is still policy room for product-specific amber box support but the ceiling of de minimis has already imposed substantial constraint on China's grain price support policies; and that despite rapid increases in non-product-specific amber box support levels, future policy space remains significant. The result also suggests that China should make appropriate adjustments to product-specific amber box support policies in accordance with WTO rules on agricultural domestic support and make proper use of non- product-specific amber box support policies.展开更多

China owns the largest population of liver diseases and the biggest number of liver resection cases. A nationwide multicenter retrospective investigation involving 112 hospitals was performed, and focused on liver resection for patients with hepatocellular carcinoma(HCC). 42,573 cases of hepatectomy were enrolled, and 18,275 valid cases of liver resection for HCC patients were selected for statistical analysis. The epidemiology of HCC, distribution of hepatectomy, postoperative complications and prognosis were finally analyzed. In the 18,275 HCC patients,81% had hepatitis B virus infection and 10% had hepatitis C virus infection. 38% of the HCC patients had normal Alphafetoprotein(AFP) level, and other 35% had an AFP level lower than 400 ng mL^(-1). In the study period, 97% of the hepatectomy for HCC were treated with open surgery, and 23.81% had vascular exclusion techniques. The operation time was(191.7±105.6) min,the blood loss was(546.0±562.8) m L, and blood transfusion was(543.0±1,035.2) m L. The median survival for HCC patients was 631 days, with 1-, 3-, and 5-year overall survival of 73.2%, 28.8% and 19.6%, respectively. Liver cirrhosis, multiple nodules,tumor thrombosis and high AFP level were risk factors that affect postoperative survival.展开更多
