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.

Objective To survey the satisfaction degree of the postgraduates in professional degree with The Joining Together of Double-Track education model in the current stage of professional degree graduate education and standardized training of residents in China. Methods According to various factors, such as the current situation of postgraduates in medical universities, we sought the opinions of relevant experts to design questionnaire. Meanwhile, to enhance the reliability of the questionnaire and the survey, we chose the postgraduates of Shengjing Hospital of China Medical University first to do the pre-survey, and according to the feedback, we adjusted part of the aspects, thus formed a formal questionnaire, which included the satisfaction with training of clinical practice ability, training of research ability, and tutors' assessment etc. Finally, the Chinese New Youth Forum online released the questionnaires, selecting the postgraduates in professional degree who were participating in, or had participated in the completion of the standardized training as the participants, which took place between March 2016 and May 2016. SPSS 16.0 was used for statistical analysis. The evaluation results of different majors were tested by Kruskal-Wallis rank sum test. Results According to the results of the survey, the aspects in the clinical resident standard-ized training that the 1000 postgraduates were more satisfied with were as follows: training time [42.8%(n=428)], training center [41.8% (n=418)], training of clinical practice ability [41.6% (n=416)], tutors [40.2%(n=402)], economic income [38.8%(n=388)], department arrangements [38.4% (n=384)], training of research ability [37.5%(n=375)]. There is a significant difference in the satisfaction degree of different pro-fessional graduate students in theJoining Together of Double-Trackeducation model (P<0.05). ConclusionThe Joining Together of Double-Track education model should be compatible with the training objectives of postgraduates in professional degree. Much more attention should be paid to the post-graduates, satisfac-tion degree with the clinical resident standardized training, as well as the requirements during the training period, improve the evaluation of graduate students' ability of scientific research, econo-mic income and so on, so as to improve the training system for the postgraduates.

Objective To evaluate the application of propfol?remifentanil closed?loop and opened?loop anesthesia in children otorhinolaryngologic operation under BIS monitoring. Methods Fourty children underwent elective children tonsillectomy and adenoidectomy were recruited for the study and randomly divided into two groups:closed?loop group(group T)and opened?loop group(group C),with 20 children each. The two groups all received total intravenous induction,then the subjects of closed?loop group were administrated with a method of system automatic regulation of plasma target control and the opened?group cases underwent manual adjustment of plasma target control method according to the BIS value during op?eration. The variables of non?invasive blood pressure(BP),heart rate(HR),pulse oxygen saturation(SpO2),electrocardiogram(ECG),bispec?tral index(BIS),the number of times the manual adjustment of propfol target control applied,and recovery time,were recorded respectively at the time points of before anesthesia(T0),immediately after intubation(T1),5 min after intubation(T2),10 min after(T3),15 min after(T4),30 min after(T5)and the removal of endotracheal intubation(T6). Results The total dosage of propfol in group T was less than the dosage in group C with dosage decrease of 9.83%;there was no significant statistical difference of the total dosage of remifentanil. Conclusion The use of propfol?remi?fentanil closed?loop anesthesia in children otorhinolaryngologic operation is safe,easy,and of strong controllability,which should be widely promoted.

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.
