METHODS: According to age, 403 patients operated on for CRC in our department were divided into group A (< 70 years old) and group B (≥ 70 years old) and analyzed statistically. RESULTS: Rectal localization prevailed in group A (31.6% vs 19.7%, P = 0.027), whereas the percentage of R0 resections was 77% in the two groups. Comorbidity rate was 46.2% and 69.1% for group A and B, respectively (P < 0.001), with a huge difference as regards cardiovascular diseases. Overall, postoperative morbidity was 16.9% and 20.8% in group A and B, respectively (P = 0.367), whereas mortality was limited to group B (4.5%, P = 0.001). In both groups, patients who suffered from postoperative complications had a higher overall comorbidity rate, with preexisting cardiovascular diseases prevailing in group B (P = 0.003). Overall 5-year survival rate was significantly betterfor group A (75.2% vs 55%, P = 0.006), whereas no signif icant difference was observed considering disease-specif ic survival (76.3% vs 76.9%, P = 0.674). CONCLUSION: In spite of an increase in postoperative mortality and a lower overall long-term survival for patients aged ≥ 70 years old, it should be considered that, even in the elderly group, a signif icant number of patients is alive 5 years after CRC resection.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

After determination of main risk factors of these diseases by analysis of variance, the authors introduce a new concept ’Illness Fuzzy Set’ and use fuzzy comprehensive evaluation to evaluate the risk of suffering from a disease for residents. Optimal technique is used to determine the weights wi in fuzzy comprehensive evaluation, and a new method ’Improved Information Distribution’ is also introduced for the treatment of small sample problem. It is shown that the results obtained by using the hybrid technique are better than by using single fuzzy technique or single statistical method.展开更多

Using hwabyung, this article describes the psychological ramifications of immigration experiences among Korean immigrant women in the United States. Data collected from an anonymous survey of adult Korean immigrant women （n = 143） were used for a statistical analysis. The findings highlight the significant effects of self-esteem, social support, financial hardship, and family cohesion on the changes in the hwabyung symptoms among Korean immigrant women. Based on the findings, the implications for practice and future study are discussed. Also discussed are the global significance of migrant women and their mental health issues.展开更多
