Objective To discuss the effect of pericardial devascularization plus gastric fundus transaction in advance schis?tosomiasis patients with portal hypertension. Methods Thirty?six advanced schistosomiasis patients with portal hypertension treated with devascularization plus gastric fundus transaction(a portal hypertension group),as well as 10 patients treated with modified Sugiura operation(a modified Sugiura operation group)in the Third People’s Hospital of Yangxin County since 2006 were chosen as the observation objects,and the clinical effects of the two groups were observed and compared. Results The op?eration time,indwelling time of stomach tube,time to taking food after operation,drainage tube removal time of the portal hy?pertension group were all shorten than those of the modified Sugiura operation group(all P<0.05). The hospitalization expenses of the two groups were(25 466.00 ± 2 888.48)Yuan and(34 517.10 ± 4 948.39)Yuan respectively,and the difference was al?so statistically significant(P<0.05). The incidence rates of portal thrombosis of the portal hypertension group and modified Sug?iura operation group were 33.33%(12/36)and 40.00%(4/10),respectively,and the incidence rates of rehaemorrhagia of the two groups 12 months after the operation were 16.67%(6/36)and 10.00%(1/10),respectively,but the differences had no sta?tistically significance(both P>0.05). In addition,1 case with delayed gastric emptying and 1 case with stomal leak of esopha?gus happened in the modified Sugiura operation group,while no corresponding complications happened in the portal hyperten?sion group. Conclusions Pericardial devascularization plus gastric fundus is a relatively easy procedure which has a good short?term clinical effect,and therefore it is suitable for application in primary hospitals. However,its long?term effect still needs fur?ther observation.

Objective To observe the changes of cell cycle on cancer cells after dihydroartemisinin and X-ray irradiation. Methods Human HeLa cells of cervical cancer with p53 mutation was used and human SiHa cells of cervical cancer with wild p53 was used as control. Flow cytometry was used to detect the effect of dihydroartemisinin (20 and 100 μmol/L) and irradiation (6 Gy)on cell cycle. Western blot was used to measure the levels of cell cycle protein. Results G2 arrest was observed in irradiated HeLa cells, which the proportion of cells in G2 phase was increased from 14.45% to 73. 58% after 6 Gy X-ray irradiation, but it was abrogated by dihydroartemisinin from 73. 58% to 48.31%in HeLa cells, and it had no change on the SiHa cells. The elevated Weel protein and the lowered Cyclin B1 protein were observed with the G2 arrest severity. The expression of radiation-induced Weel protein was suppressed and the Cyclin B1 protein was increased after dihydroartemisinin treatment, which was in accordance with the abrogation of radiation-induced G2 delay. Conclusions The main effect of irradiation on cell cycle of p53 mutated HeLa cells is G2 arrest. Dihydroartemisinin could abrogate it, which is associated with the changes of Weel protein and Cyclin B1 protein. In Siha cells, the main effect of irradiation on cell cycle is G1 arrest, and dihydroartemisinin has no effect on it.
