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 evaluate the efficacy of narrow-band imaging (NBI) in diagnosis of color-ectal neoplasm. Methods A total of 96 colorectal neoplasm from 78 patients were observed under NBI, and the findings were compared with those from magnifying chromo-endoscopy and pathologic examinations. Re-suits The sensitivity of conventional colonoscopy in diagnosis of polyps was 78. 7%, which was increased to 99% (P < 0. 05) under NBI, with the clear identification of the shape and boundary of the lesions. Magnif-ying NBI colonoscopy provided images of pit patterns similar to those from chromo-endoscopy in diagnosis of type Ⅱ , ⅢL, Ⅳ and ⅤN, which showed better recognition than conventional colonoscopy, but less sensitiv-ity than chromo-endoscopy. Superficial vascular morphologic features could be better classified with NBI, with sensitivity of 100% and specificity at 87. 8%, which was superior to conventional colonoscopy but infe-rior to chromo-endoscopy. Conclusion Both chromo-endoscopy and NBI colonoscopy have better sensitivity and specificity in detection of colon polyps, while chromo-endoscopy reveals clear superficial structure of le-sion and pit pattern, and NBI demenstrates capillary morphology, which can distinguish neoplasm from non-neoplasm colorectal lesions. NBI, easy and convenient to switch, is an effective technique to make early di-agnosis of colorectal neoplasm.

Objective To evaluate the effect of transcutaneous electrical acupoint stimulation(TEAS)on emergence agitation in children under?went general anesthesia with sevoflurane. Methods Sixty children aged 3?6 years underwent adenoidectomy and tonsillectomy were selected and randomly divided into two groups:TEAS(group T,n=30)and control(group C,n=30). After venous induction,the general anesthesia was main?tained with sevoflurane. Group T received continuous TEAS at point hegu and neiguan after anesthesia induction till the end of operation. Control group were not given TEAS. The change of the blood flow dynamics in the process of anesthesia,the time of extubation,awaking time and the time in PACU were recorded. The emergence agitation,postoperative nausea and vomitting and respiratory depression were observed. Results There were no significant differences in gender,age,weight,anesthesia time,and operative time between the two groups (P>0.05 ). There was no significant difference in extubation time,awaking time and time in PACU between the two groups(P>0.05). The mean arterial pressure and heart rate in group T were lower than those in group C at the time of extubation and in PACU(P<0.05). The emergence agitation scale in group T was lower than in group C(P<0.01). There was no significant difference in incidence rate of PONV and respiratory depression between two groups. Conclusion TEAS can reduce emergence agitation in children with sevoflurane?induced general anesthesia,but not prolong extubation time,awaking time and time in PACU. In addition,it does not increase the incidence of respiratory depression.

The paper aimed to find the optimal combination and evaluation of the interactions of antitumor effect of the curcumin (Cur) and adriamycin (ADM) in vitro. According to the factorial design and data characteristics, the parameter method combined with the response surface approach were used to analyze the pharmacodynamic interactions of in vitro antitumor effects of the combination of Cur and ADM at different dosages. The results showed that the dose-effect relationship of the combination with the ratio of ADM-Cur 1:3 showed significant differences in comparison with either used alone. The dose-effect curve was shift left in combination. The combination of adriamycin (ADM, 0.693-2.132 micromol L(-1)) and curcumin (Cur, 2.047-6.304 micromol L(-1)) with a fixed ratio (1:3) showed a synergism. With increasing doses of the combination, there is an additive effect. Computer simulation showed a trend of decreasing difference between the observed and expected effects with the dose increasing in Cur from 6.304 to 16.0 micromol L(-1) and ADM from 2.132 to 5.3 micromol L(-1). The response surface analysis showed the optimal combination to be Cur 18.50 micromol L(-1) and ADM 3.89 micromol L(-1) with a ratio of 5:1. This study suggests that the parameter method combined with the response surface analysis provides richer and more reasonable information, and is helpful for quantitative design of drug combination therapy and to describe the nature and degree of drug interaction.
