Objective To compare the efficacy of sevoflurane combined anesthesia and propofol combined anesthesia in elderly patients undergoing abdominal surgery.Methods Sixty patients aged 65-80 yr scheduled for elective abdominal surgery under general anesthesia were randomly divided into 2 groups (n = 30 each): sevoflurane group (group S) and propofol group (group P).Anesthesia was induced with TCI of sufentanil and propofol.The initial target effect-site concentration (Ce) of sufentanil was set at 0.25 ng/ml and initial target plasma concentration (Cp) of propofol set at 2.0 μg/ml,and then both concentrations were increased in 0.5 μg/ml increment when they reached the balance until loss of consciousness.Tracheal intubation was facilitated with rocuromitm 0.6 mg/kg and the patients were mechanically ventilated.Anesthesia was maintained with inhalation of sevoflurane (end-tidal concentration set at 1.0%-2.0%) in group S,TCI of prepofol (Cp set at 2-4 μg/ml) in groups P, and sufentanil by TCI ( Ce set at 0.15 ng/ml) and iv infusion of vecurenium 0.15 mg·g-1·h-1 in both groups. .BIS value was maintained at 40-60,and changes of MAP and HR were less than 30% of the baseline value in both groups.The use of vasoactive drugs during perioperative peried,time of awakening,extubation and consciousness were recorded and compared between the 2 groups.Results The usage rate of urapidil was significantly decreased,and the awakening time,extubation time and consciousness time shortened in group S compared with group P.Conclusion Sevoflurane-sufentanil combined anesthesia provides better hemodynamic stability and faster recovery than propofol-sufentanil combined anesthesia in elderly patients.

Objective To explore the mechanism of Xiao Chaihu decoction in t he treatment of endometriosis in rats.Methods The rat model of endometriosis w as established. Fas and Caspase- 3 protein expression in the eutopic endometriu m and eutopic endometrium were observed by immunohistochemical method.Results The protein expression of Fas and Caspase- 3 in ectopic endometrium of Xiao Cha ihu decoction group was higher than that in the eutopic endometrium, while the r esult in the control group was just the opposite. No significant difference was shown in Danazol group. Conclusion The therapeutic mechanism of Xiao Chaihu de coction for endometriosis may be related to the promotion the apoptosis of ectop ic endometrium tissue by increasing Fas protein expression.

Objective To study the effect of Taohongsiwu decoction(THSWD) on the VEGF expression and the micrangium regeneration of callus tissue in bone stump. Methods 65 Japanese rabbits were divided into four groups randomly, three groups were given orally with THSWD, Yandining tablet, distilled water respectively after the right radial bone fracture model was established by operation, and the other group served as control. At the 7th,15th,21th and 35th day after fracture, immunohistochemical method was used to detect the expression of VEGF, and the histochemical staining was used to detect the micrangium change of callus tissue in bone stump. Then the data were compared and analysed. Results VEGF expression level was higher in THSWD intvervening group than that in the other groups, and the decrease of VEGF expression was not obvious after the peak value at 15th day. The callus micrangium regeneration and the remodeling of callus in THSWD intervening group were better in all phase than those in the other groups. Conclusion THSWD could improve the VEGF expression of callus tissue, accelerate the micrangium regeneration in bone stump and promote the healing of fracture.

Objective To evaluate the influencing factors for postoperative odynophagia in elderly patients undergoing intraoperative transesophageal echocardiography (TEE) examination for cardiac surgery.Methods A total of 96 patients with intraoperative TEE examination for cardiac surgery was divided into two groups:the elderly group (patients aged ≥65 years,n=60) and the young group (patients aged ＜ 65 years,n =36).Clinical data were retrospectively analyzed.Postoperative odynophagia was assessed by number rating scale (NRS) scores.Characteristics of postoperative odynophagia were compared between the two groups.Influencing factors for postoperative odynophagia were analyzed by multivariable logistic regression analysis.Results The incidence of postoperative odynophagia and the average NRS score were higher in the elderly group thanin the young group [88.3％ vs.66.7％,(2.6±1.7) vs.(1.4±0.9),P＜0.05 or 0.01].Multivariate logistic regression analysis showed that preoperative oral lidocaine plasmagel,oropharyngeal mucosal injury and duration of TEE insertion were independent influencing factors for postoperative odynophagia (all P＜0.01).Conclusions The incidence of postoperative odynophagia is higher and the degree of odynophagia is more serious in elderly patients undergoing intraoperative TEE examination for cardiac surgery.Postoperative odynophagia can be relieved by applying the preoperative oral lidocaine plasmagel,reducing oropharyngeal mucosal injury and shortening the duration of TEE insertion.

Objective To investigate the feedback of eight-year program students to problem-based learning ( PBL ),and find out the existing problems and solutions.MethodsThe questionnaire survey was made in the eight-year program students.ResultsApplication of PBL could achieve good feedback.It helped to enhance the self-directed learning,expressing ability,accessing resource skill,and team spirit.ConclusionAlthough there are some problems in the practice of PBL,PBL is a good teaching method in eight-year program education.

Objective To compare the clinical efficacy and carry out analysis on pharmacoeconomic cost-effect of three therapeutic schemes in the treatment for stroke. Methods Through a retrospective survey method, 115 stroke patients, based on different treatment methods, were divided into 3 groups:Xuesaitong group (A), carthamin yellow group (B), and Xueshuantong group (C). An analysis on pharmacoeconomic cost-effect was conducted. Results The costs of three therapeutic schemes were 1030.4 yuan, 1876 yuan, and 1545.6 yuan, respectively. The total effective rates of stroke patients in groups A, B and C were 85.37%, 88.57% and 90.04%, respectively. The cost-effect ratios of groups A, B and C were 12.07, 21.18, and 17.17. The added cost-effect ratios of groups B and C compared with group A were 264.25 and 110.32, respectively. Conclusion Xueshuantong Injection has more pharmacoeconomic advantage than Xuesaitong and carthamin yellow Injections in treating stroke.
