Progressive assessment is one of the methods adopted by colleges and universities to evaluate the comprehensive quality of undergraduates.It can provide objective references for various awards and selections.Most colleges used static and transverse methods; based on these methods,advantages and disadvantages of individual undergraduates were compared with general groups,but feedback and forecast functions of assessment can not be realized.Therefore it is necessary to transform our conceptions and practice progressive assessment on comprehensive quality of undergraduates.We can learn from the relevant conceptions and methods in enterprise management and use data envelopment analysis to exclude the influence of different basic conditions of undergraduates.These undertakings are of great importance to truly reflect undergraduates' effective progress degree,guide them to test and evaluate themselves correctly and to advance comprehensive quality continuously.

Objective To learn healthy lifestyle and behavior literacy of residents living in Xicheng District of Beijing between 2008 and 2012 and to explore the influencing factors of healthy lifestyle and behavior literacy.Methods A total of 1 347 or 2 900 adults aged 18-60 years old were recurited from Xicheng District by using multistage stratified cluster sampling method in 2008 and 2012,respectively.Chisquare test and non-conditional logistic regression were used to analyze the effectiveness of 2-year intervention on healthy lifestyle and behavior literacy.Results The rate of healthy lifestyle and behavior literacy was 14.8％ vs.30.8％ in 2008 or 2012,respectively (x2=123.574,P＜0.05).For those with relatively lower education level (e.g.junior high school or below),the figure showed no statistically significant difference (x2=1.378,P＞0.05).In multivariate logistic regression analysis,female (odds ratio (OR)=1.350),education level (college/bachelor degree:OR=2.035,master degree or above:OR=2.554),monthly family income (＞5 000 RMB:OR=1.399) and investigation time (2012:OR=2.278) were influencing factors of healthy lifestyle and behavior literacy.Conclusion Remarkable improvement in healthy lifestyle and behavior literacy during 2012 as compared to 2008 could be attributed to the comprehensive interventions.In the future,those of low-literacy or low-income should be the mian target of modification of healthy lifestyle and behavior literacy.

Laparoscope has been widely recognized as a treatment of distal gastric cancer.Totally laparoscopic distal gastrectomy and laparoscopy-assisted distal gastrectomy are two main types of laparoscopic distal gastrectomy.Apart from a smaller incision,some other advantages which totally laparoscopic distal gastrectomy has is the key point for further study.The thesis aims to compare totally laparoscopic distal gastrectomy to laparoscopy-assisted distal gastrectomy,and to analyze the characteristic in the aspect of operation time,the degree of pain,postoperative complications and the time of gastrointestinal recovery via collecting a great quantity of literatures.

BACKGROUND:The studies of plantar pressure mainly focus on barefoot,while the research regarding the effect of shoes on kinetic parameters is little.OBJECTIVE:To explore the peak value of foot plantar pressure between barefoot and wear shoes in max force,max pressure,load rate and impulse during the natural walk,and to search the parameter relationship between barefoot and with shoes.DESIGN,TIME AND SETTING:The the same body control analysis was performed at the Laboratory of Sports and Human Science of Nanjing Institute of Physical Education in October 2007 PARTICIPANTS:A random sampling method was used to selected 10 male college students from the Nanjing Institute of Physical Education which aged(21.00?2.40) years,weighing(71.53?3.16) kg,body height(176.32?2.62) cm,and foot length(25.67?0.92) cm.According to the regulation,informed consent was obtained from each participant.METHODS:Normal gait of 10 participants were measured by Foot scan7.0 plantar pressure test system,including barefoot and with shoes.MAIN OUTCOME MEASURES:The distribution of maximum force,maximum pressure,load rate and impulse.The parameter relationship between barefoot and with shoes were assessed in the study.RESULTS:The max force existed in the area of heel medial,the second metatarsal and the third metatarsal.The minimum force existed in the area of the toes 2-5 and the fifth metatarsal.The max pressure of barefoot existed in the area of the toes 2-5 and the second metatarsal and heel during walking.The load rate of heel was the highest.The max impulse existed in the second metatarsal and the third metatarsal and heel.The minimum impulse existed in the toes 2-5 and the fifth metatarsal.When wearing shoes,the max force existed in the area of the mid foot and toe1,The minimum force existed in the area of the toe 5,during walking the max pressure existed in the area of the instep.The load rate of the mid foot and heel was the highest.The max impulse existed in the mid foot.The minimum impulse existed in the fifth metatarsal.CONCLUSION:The parameters of forefoot,instep,and heel were larger than barefoot during walking,especially those of the phalanges2-5 and instep.

Objective To repair the experimental femoral head necrosis with the implantation of tricalcium phosphate (TCP) loaded with human bone morphogenetic protein-2(hBMP-2) gene transfected bone marrow derived mesenchymal stem cells(BMSCs). Methods Established the animal models of femoral head necrosis in 22 goats by the ligation of the lateral and medial circumflex femoral arteries and delivery of liquid nitrogen into femoral head. 4 goats served as the control group without any treatment. 3 weeks after surgery, necrotic bone in the other 18 goats were removed and TCP loaded gene transfer cells were implanted into the femoral head with BMP-2 gene transfected BMSCs in right side and ?-gal gene transfected BMSCs in left side. BMP-2 concentrations in femoral head were tested by the ELISA at 1st, 2nd, 3rd week after implantation. Histological observation was done before and at 6th, 10th, 16th week after implantation. New bone volumes (NBV) were measured at 16th week after implantation by the histomorphometry method. X-ray was taken at 16th week after operation in untreated group and after treatment in BMP-2 group and ?-gal group. Results The concentration of BMP-2 in femoral head of BMP-2 group was higher than that of ?-gal group at different time point. Empty lacunae and fibrotic marrow were demonstrated before implantation. New bone was evident in the implantation field of BMP-2 group while fibrous tissues were evident in that of ?-gal group at 6th, 10th and 16th week after treatment. Histomorphology analysis indicated that the NBV in BMP-2 group was significantly higher than that in ?-gal group. Articular surface collapse were observed in the X-ray photograph of untreated group. Regular shape and normal density of femoral head in BMP-2 group compared with the irregular shape and low density of femoral head in ?-gal group could be demonstrated in the X-ray photograph 16 weeks after treatment. Conclusion Implantation of the TCP loaded with human BMP-2 gene transfected BMSCs could repair early-stage experimental femoral head necrosis.

Objective: In order to search the credible parameters of evoked potentials (EP) for the depth of anesthesia. Method: The end-expiratory concentration of isoflurane was increased gradually from 0.2MAC by step of 0.1MAC in each of ten volunteers. The change of EP and the consciousness were observed at every end expiratory anesthetic concentrations. The explicit and implicit memories about intra-experiment events were investigated an hour after stopping inhalation of isoflurane. Result: The explicit memory disappeared at 0.2 and 0.3MAC of isoflurane without the stimulation of pain; The response to command disappeared at 0.3 and 0.4MAC; 0.4MAC of isoflurane could not vanish implicit memory in all subjects. The latencies of waves Pa and Nb of the MLAEP and P_(25) of the SEP prolonged gradually with increased concentrations of isoflurane in a linear relationship, and varied with the changes of response to command. The latency corresponding to the partial response increased significantly compared with that to the full response, but without difference between the partial and no response. Meanwhile the latencies of waves Pa, Nb and P_(25) increased significantly with the disappearances of explicit and implicit memory, without differences between the conscious and unconscious awareness. The critical values of latencies about those waves which could be applied to assess the disappearance of explicit memory, were defined. Conclusion: The disappearance of consciousness is not all-ornone but gradual. The sequence of disappearance about consciousness is explicit memory, response to command, then implicit memory. There is no explicit memory about stimulation of pain after response to command has vanished, but implicit memory may still exit. The waves Pa and Nb of MLAEP and the wave P_(25) of SEP may be regarded as important parameters to evaluate the depth of anesthesia about consciousness.

Objective: To study amnesia and EEG changes caused by midazolam during epidural and spinal anesthesia. Method: Forty cases with epiduraI anesthesia were divided randomly into 4 groups in double-blind method. 0.15mg/kg and 0.10mg/kg midazolam,0.20mg/kg diazepam and 2ml normal saline were administered respectively and intramuscularly 30 min before anesthesia. The changes of EEG before and after the administration,sedation degree,the amnesia rate and degree for the procedures of anesthesia and the psychological state after operation were observed synchronously. Result: The sedation degree was in accordance with amnesia effect after intramuscular midazolam. The amnesia rate caused by 0.10mg/kg midazolam was 70%,but 90% of them was part amnesia. 0.15mg/kg midazolam produced 100% total amnesia. In midazolam groups,the ? and ? relative powers were increased,but the 6 and ? relative powers were decreased greatly. There were no obvious changes on the Pa and Nb waves in four groups. Conclusion: Intramuscular midazolam can completely prevent the patient from recalling for the process of anesthesia in dose-dependent way. The effective site of anterograde amnesia of midazolam is not located at cortical hut at the hippocampus and thalamus. This kind of amnesia belong to axis amnesia
