Objective To observe the effect of transcutanous acupoint electrical stimulation(TAES)and dexmedetomidine on postoperative cogni?tive dysfunction in female patients underwent laparoscopic surgery. Methods Nighty patients scheduled for laparoscopic surgery were recruited in this study and randomly divided into control group(group C,n=30),TAES group(group T,n=30)and dexmedetomidine group(group D,n=30). In group T,patients received TAES treatment 30 min before the anesthesia until the end of the surgery at Neiguan(PC 6)and Zusanli(ST 36). The frequency was 2/100 Hz. In group D,patients were intravenously administrated with dexmedetomidine(0.5μg/kg)before the induction. All the patients were given routine general anesthesia. Drugs induced were sulfentanyl,etomidate and cisatracurium. Sevoflurane was given to main?tain the bispectral index(BIS)between 40 and 55. The time of extubation and in PACU was recorded. The serum S100βlevel was assessed at pre?operation(T0),the end of operation(T1)and 24 h after operation(T2). Mini?mental state examination(MMSE)was adopted to evaluate and re?cord the changes in cognitive function 1 day before operation and 24 h after operation. Results The incidence rate of POCD in group T and group D were lower than that in group C(all P<0.05). The level of S100βin group T and group D was lower than those in group C at T1 and T2 separately (all P<0.05). The time of extubation and time in PACU in group D were longer than those in group C and group T(all P<0.05),and the incidence of bradycadia in group D was higher than that in the other groups(all P<0.05). Conclusion TAES and dexmedetomidine reduce the incidence of cognitive dysfunction,decrease the release of S100βprotein. However,dexmedetomidine increases bradycadia,and prolongs extubation time and stay time in PACU. Hence,TAES deserve to be recommended practically.

Objective To observe the clinical efficacy of dexmedetomidine combined with sufentanil in the treatment of self?control intravenous an?algesia after laparoscopic surgery. Methods Sixty patients,who underwent laparoscopic sugery and general anaesthesia,American Society of Anes?thesiologistsⅠtoⅡ,were randomly divided into dexmedetomidine(DS)group and sufentanil(S)group,with thirty cases in each group. Group S received sufentanil 2μg·kg-1 and ramosetron hydrochloride 0.3 mg;group DS received sufentanil 2μg·kg-1,dexmedetomidine 200μg and ramose?tron hydrochloride 0.3 mg. Drugs of both groups were dissolved in saline 100 mL,with a loading dose of 4 mL,background infusion of 2 mL·h-1,con?trolled dose of 0.5 mL·h-1,and the lockout time was 15 min. Visual analog scale(VAS)score,Ramsay sedation scale(RSS)score,sufentanil cu?mulative consumption after surgery at 2 h,4 h,6 h,12 h,24 h were recorded,as well as the adverse reactions such as nausea,the occurrence of vomiting and chills within 24 h after surgery,and the satisfaction of patients with postoperative analgesia. Results Six hours post operation,VAS score of group DS was significantly lower than the group S(P<0.05);2 hours post operation,RSS score of group DS was significantly higher than the group S(P<0.05);the cumulative consumption within 6 hours after sufentanil was significantly lower in group DS than group S(P<0.05). The incidence of nausea,vomiting,chills and other adverse reactions were significantly higher in group S than group DS(P<0.05). Conclusion Compared with the simple application of sufentanil,dexmedetomidine combined with sufentanil for postoperative analgesia achieve better analgesic effect,reducing the amount of sufentanil,while reducing the associated sufentanil adverse reactions,improve patient comfort and satisfaction of post?operative analgesia.

OBJECTIVETo evaluate the long-time effect on allitridum and selenium in preventing cancer of digestive system.
METHODSPersons who were recruited into the intervention group and took allitridum and selenium to prevent gastric cancer in Qixia county of China from 1989-1991 were followed up to 2001 and data of deaths was collected. The long effect on allitridum and selenium in preventing cancer of digestive system was analysed.
RESULTSData were compared to placebo group five years (1992-1996) after the termination of intervention to have found that the accumulative mortality rate of all cancer, digestive system cancer and gastric cancer had decreased 45.5%, 41.2% and 63.3% in the intervention group respectively. By stratum analysis, accumulative mortality rate of all cancer, digestive system cancer and gastric cancer had decreased 51.5%, 51.5% and 67.7% in males of the intervention group, respectively. Relative risks for males in the intervention group were 0.48, 0.47 and 0.30 times more than the placebo group, respectively. All of them were statistically significant. Relative risks for females in the intervention group were 0.74, 0.92 and 0.70 times more than placebo group. Six to ten years later after the termination of intervention, the accumulative mortality rate and relative risk of all cancers in two groups became similar.
CONCLUSIONAllitridum and selenium had the effect of decreasing the incidence risk of digestive cancer with a protective rate more than 50% for five years after the termination of intervention program.
