Objective To observe the pituitary tumor transforming gene (PTTG), estradiol-stimulated protein 1 (ESP1) expressions in S, G 2/M phases in A549, SPC-A-1 cell lines. Methods The mammalian cells for cell cycle was synchronizated by thymidine, the total RNA in the S, G 2/M phases was collected, and the total RNA was observed by Real-time PCR. Results PTTG expression in A549 and SPC-A-1 cell lines was higher in S phase than that in G 2/M phase while no PTTG expression in MRC-5 cells in S, G 2/M phases. ESP1 expression in A549, SPC-A-1, MRC-5 cell lines was lower in S phase than that in G 2/M phase. Conclusion That no PTTG in S and G 2/M phases in the normal cell line and PTTG expression in the lung cancer cell line higher in S phase than that in G 2/M phase suggested that the aneuploidy may be caused by the overexpression of PTTG. ESP1 expression was lower in S phase than G 2/M phase in all of the three cell lines, suggesting that sister chromatids separation depend on the active ESP1.

Objective To evaluate Satoh typing for tumor thrombi in the bile duct in patients of hepatocellular carcinoma.Methods A retrospective analysis was made on clinical data of 51 hepatocellular carcinoma patients with tumor thrombi in the bile duct undergoing hepatectomy in Eastern Hepatobiliary Surgery Hospital from Jan 2004 to Dec 2005.The cumulative disease-free survival by the three Satoh types were compared by Kaplain-Meire analysis.and log-rank test.Results There was no operationrelated motality and the postoperative complication rate was 22%(11/5 1).The overall survival rates at 1-and 2-years were respectively 76%(39/51)and 55%(28/51).The overall disease-free survival rates at 1-and 2-years were respectively 53%(27/51)and 22%(11/51).The disease-free survival rates at 1-and 2-years in type Ⅰ patients were respectively 61%(19/31)and 29%(19/31).The disease-free survival rates at 1-and 2-years in type Ⅱ and Ⅲ patients were respectively 35%(7/20)and 10%(2/20).The cumulative disease-free survival rates at 2-years was statistically different between type Ⅰ,type Ⅱ and Ⅲ (v=7.489,P=0.006)).Conclusions Satoh typing of tumor thrombi helps to determine the surgery plan and assess the prognosis of hepatocellular carcinoma with tumor thrombi in the bile duct.

Objective To study the clinical effect of personalized intervention on elderly patients with colostomy after Miles operation for rectal carcinoma. Methods 114 cases elderly patients with colonic stoma after Miles operation for rectal cancer from June 2014 to January 2016 were divided into control group and observation group by random number method, 57 cases in each. The control group were treated with routine intervention, while patients in observation group was treated with personalized intervention. the self-care ability score before intervention, the incidence of complications, intervention satisfaction and life quality score were compared between the two groups at the same time. Results The total complication rate in the observation group was significantly lower than that in control group ( 5.25% vs 22.80%) (χ2 = 8.36, P = 0.000); the intervention satisfaction of the observation group was significantly higher than that in control group (91.23% vs 75.44%) (χ2 = 6.60, P = 0.010). After intervention, the self-care ability score and life quality score of observation group were significantly higher than that in control group (P < 0.01). Conclusion The personalized intervention can reduce the complications, significantly improve the patients' life quality score and self-care ability, and effectively alleviate the negative situation, improve the patients intervention satisfaction, with a higher development value, it is worth of clinical promoting.
