This study was designed to analyze prognostic factors after surgical procedure for ICCs. Methods： A retrospective clinical analysis was made in 183 cases of ICC, admitted to Department of Hepatic Surgery, Eastern Hepatobiliary Surgery Hospital, Second Military Medical University, Shanghai, China, from December 1996 to July 2003. Fifteen clinicopathologic factors that could possibly influence survival were selected. A multivariate analysis of these individuals was performed using the Cox Proportional Hazards Model. Results： The accumulative 1-, 3-and 5-year survival rates of the patients were 51.3%, 21.6% and 11.8% respectively. The statistical analysis showed that surgical procedure, lymph node metastasis, serum level of CA19-9 and pathological differentiation grade affected postoperative survival significantly, but transfusion, postoperative radiotherapy and chemotherapy, diameter of tumor, serum level of AFP, cirrhosis, preoperative total serum bilirubin level （TBIL）, ratio of albumin to globulin （A/G）, sex and age were not significant factors influencing postoperative survival. Conclusion： Major hepatectomy with systematic lymph node dissection may be recommended for the surgical treatment of ICC. Aggressive treatment and prevention on postoperative intrahepatic recurrence and lymph node metastasis are important strategy to improve the survival for ICC.展开更多

However, the influence of loading sequence on the dragload and downdrag for pile foundation is seldom studied. In this paper, a three-dimensional numerical model was established using FLAC3D. Compared with the results of model test, the established model could be used to study the NSF of pile foundation. The influencing factors were discussed including the length-diameter ratio of pile and the loading sequence of pile head load and surcharge. A case history was analyzed using FLAC3D. The calculated results are in good agreement with the measured results. It is concluded that the dragload and downdrag are remarkably influenced by the loading sequence of pile head load and surcharge. The dragload and downdrag reach the maximum values under the condition of surcharge after pile head load.展开更多

According to the surveys, per capita net income level of the villages maintained consistent growth, as indicated by survey data on the years of 1930, 1936, 1957, 1986 and 1997, except for 1946 which saw decline, and enjoyed rapid growth particularly in the years of reform and opening-up after 1986. The changes reflect the national trendsustained decline of the proportion of net income from household operations versus eontinuous growth of the proportion wages income takes of the whole income.展开更多

基金For the purposes of this study, the eleven villages of Baoding refer to： Liluohou, Hejiaqiao, Dongguzhuang, Nandeng, Caijiaying, Xuezhuang, Gushang, Xiezhuang, Mengzhuang, Dazhuze, Dayang. However, the data in the 1986 survey only covers six villages. This study was sponsored by National Social Science Foundation （10 CJL008） and the innovation project of CASS＇s Institute of Economics, ＂Rural household economic transition of Wuxi and Baoding during the process of a hundred years of industrialization and urbanization.＂ The authors appreciate support from various scholars.
