OBJECTIVE:To investigate the effects of mannitol combined with dexamethasone on related indexes of patients with infectious brain edema.METHODS:A total of 120 patients with infectious cerebral edema were divided into control group (60 cases) and observation group (60 cases) according to therapy plan.Control group was given Furosemide injection 20 mg+20％ Mannitol injection 1 g/(kg,time)+0.9％ Sodium chloride injection 10 mL intravenously,every 6 h,3 days later adjusting drug dose according to the disease condition of patients.Observation group was given Dexamethasone injection 10-20 mg+20％ Mannitol injection 1 g/(kg·time)+ 0.9％ Sodium chloride injection 10 mL intravenously,every 6 h,3 days later adjusting drug dose according to the disease condition of patients.A treatment course lasted for 7 d,and both groups were treated for 2 courses of treatment.The levels of NO,IL-1 and TNF-α,mortality and the occurrence of sequelae before and after treatment as well as the occurrence of ADR were observed in 2 groups.RESULTS:Before treatment,there was no statistical significance in the levels of NO,IL-1 or TNF-α between 2 groups (P＞0.05).After treatment,the levels of NO,IL-1 and TNF-α in 2 groups were significantly lower than before treatment,and the observation group was significantly lower than the control group,with statistical significance (P＜0.05).The incidence of mortality,sequelae and ADR in observation group were significantly lower than control group,with statistical significance (P＜0.05).CONCLUSIONS:Mannitol combined with dexamethasone can reduce inflammatory factor level,the incidence of sequelae and mortality,without increasing the incidence of ADR.

Objective To observe the effect of rational-emotive therapy(RET)on rehabilitation of patients with depression after stroke.Methods 62 hemiplegic patients with depression after stroke were randomly divided into the RET group and control group with 31 cases in each group.All patients were evaluated with Hamilton Rating Scale for Depresstion(HAMD)and Barthel Index(BI)before and after treatment.Results After treatment,the scores of HAMD and BI of the patients in the RET group was superior to those in the control group(P<0.01).Conclusion The rational-emotive therapy is effective to improve not only depressive symptoms but also the quality of living.

Objective To observe the effects of bisphenol A (BPA) on the reproductive function in F1 mice. Methods Pregnancy mice were divided into four groups randomly. From the beginning of pregnance,the mice in experimental groups were given BPA with 30,120,360 mg?kg-1?d-1 until the new mice were born. The mice in control group were given the same volume of corn oil. When the young mice were 30 d, the sperm malformation rate,the activities of lactic acid dehydrogenase(LDH) and glucose-6-phosphate dehydrogenase(G-6-PD) of testicle,the organ coefficient, the histopatholgical changes of testicle in male mice were examined. Results The form of the epithelial cells of seminiferous tubules was disordered. The number of mature spermatozoa was decreased. This changes were more and more with the increase of BPA dose. Compared with control group,organ coefficients in low and large dose groups reduced,LDH activity and G-6-PD activity in middle and large dose groups decreased,LDH activity in low dose group increased. The sperm malformation rates in experimental groups increased as the increase of BPA dose, the differences were remarkable(P

Objective: To understand AIDS knowledge of the college students,to provide scientific evidence for making out the strategy of health education and synthetic prevention measure purposely.Methods An anonymous questionnaire was conducted with face to face interview to investigate the college students in Xi'an, and the software Epi info 5.0 was used to perform the statistical analysis of the data. Results 70.5% of university students knew the whole name of AIDS. As to three ways of HIV transmission, the investigation shows that 49.1% of college students knew three main ways. The 26.5% of college students mistakenly think that mosquito could transmit HIV. In general, the old, the married the literate, and medical students get more knowledge about AIDS than the young,the unmarried,the illiterate, and other major students. Conclusion The college students who are one of the most dangerous groups infected AIDS have poor knowledge. The situation of poor AIDS knowledge is extremely unfit to the prevalent tendency of AIDS, which our country is being faced. We suggest that the college students should be educated intensively on the health knowledge of AIDS especiallis beingy for freshmen.

0.05). The morphological changes were observed in the cochlea. Moreover, the changes of cochlear tissues under the optical microscope wasa lot of akaryotes were found in the blood capillary of cartilaginous tissue in the rats of 30 minutes after rammed; a great quantity inflammatory cells were observed in the blood capillary of cartilaginous tissue in the rats of 1 day rammed. The changes of morphology coincided with the results of DPOAE. CONCLUSION Outer hair cells may be injured by cerebral concussion and the changes were showed by DPOAE and ABR.

It is important to bring the principal role of medical students into full play and to develop their learning motivation and enthusiasm in order to obtain the satisfactory teaching effect in the clinical practice of preventive medicine and pediatric dentistry.Methods of timely summing-up,self-evaluation,making assumption and pair combination should be recommended.Cultivation for medical students should focus on the idea for diagnosis and treatment,skill of clinical practice and ability of doctor-patient communication.

Object: To know the situation of college students' knowledge about STDs and to help special department to give an aimed education. Methods: 1020 students were investigated by questionnaire and the data analyzed by the Epi5.0. Result: College students' knowledge about STDs were very little. Just 12.2% of these students know exactly the name of STDs which should be key prevent. About the knowledge of transmission and prevention of STDs, the married, older, higher educated and medical students were better than the corresponding other students. Conclusion: The education of knowledge about STDs should be strengthened in university, especially for freshmen.

Objective To studythe role of p16 and cyclin in the genesis and development of endometrial car-cinoma. Methods 12 cases of normal endometrium, 22 cases of proliferative endometrium and 41 cases of endome- trial carcinoma were detected for the expression of p16 and cyclin D1 by means of immunohistochemical S-P. Results In normal endometrium p16 was expressed while cyclm D1was almost negative in the proliferative phase, but both of them were negative in the secretory phase. Among the groups of the simple and compound hyperplasia, the atypical hyperplasia and the endometrial carcinoma,the expression of p16 showed a descending tendency, while the expression of cyclin showed an ascending tendency. In endometrial carcinomas the expression of p16 was significantly lower than that of normal endometrium and proliferative endometrium (P<0. 01 ,P<0.05). However, the expression of cy- clin in proliferate endometrium and endometrial carcinoma was significantly higher than that in normal endometri- un (P<0. 05,P<0. 01). The overexpression of cyclin D1 in the atypical hyperplasia group was obviously different from that in the simple and compound hyperplasia group (P＜0.01). In endometrial carcinoma,the expression of p16 was decreasing with the descending of cell differentiate degree, on the opposite, the expression of cyclin was in-creased and there existed a negative correlation between them. It was also observed that the overexpression of cyclin was significant different between and ( P ＜0. 01 ). Conclusionp1 6 is a negative regulating factor of cell cycle in endometrial carcinoma, while cyclin is a positive one. Both of them are important in the genesis and devel-opment of endometrial carcinoma. The Iow expression of p1 6 and the overexpression of cyclin are related with the malicious biological behaviors of endometrial carcinoma and maybe play an important role in the judgement of prog- nosis. Overexpression of cyclin may be an earlier molecular event in the genesis of endometrial carcinoma.

Objective To analyze the ecological environmental differences of hibernation hole and temporary hole of Himalayan marmot based on global positioning system (GPS),remote sensing (RS) and geographical information system (GIS) in Yushu City,Qinghai Province.Methods Hibernation holes and temporary holes were located based on GPS.Ecological environment factors related with Himalayan marmot,such as land surface temperature (LST),digital elevation model (DEM),normalized different vegetation index (NDVI),were extracted based on RS and GIS.The ecological environment differences between hibernation hole and temporary hole were explored based on epidemiological statistical method.Results Monthly LST (degree Kelvin,K) of hibernation hole was slightly higher than that of temporary hole in the same period.Yearly day LST of hibernation hole was 1.1 K higher than that of temporary hole in the same period.Yearly night LST of hibernation hole was 0.3 K higher than that of temporary hole in the same period.Monthly NDVI of temporary hole was slightly higher than that of hibernation hole in the same period.Yearly NDVI of temporary hole was 0.001 higher than that of hibernation hole in the same period.DEM of temporary hole was about 40 m higher than that of hibernation hole.The top two ratios of soil type factors were both alpine meadow soil and dark felty soil for hibernation hole and temporary hole,which were 62.1％ and 29.3％,64.4％ and 25.6％.The top two ratios of land cover factors were both rainfed cropland and mosaic cropland for hibernation hole and temporary hole,which were 43.3％ and 25.8％,40.0％ and 26.2％.Conclusions Soil type factors and land cover factors for hibernation hole and temporary hole are similar.Lower DEM and higher LST are chose for hibernation hole,and better NDVI is chose for temporary hole,which is good for food intake.

OBJECTIVE: To observe the change of auditory brainstem response (ABR) in hearing deprivation rat model induced by bilateral cochlears ablation at different time points. METHOD: Forty SD rats were randomly divided into four experiment groups including 2-week group, 4-week group, 6-week group, 8-week group and four control groups with 5 rats (n = 10) in each group. Then bilateral cochlears ablation was applied to experiment groups. The threshold value of ABR was measured at different time and latent period of each wave was compared. RESULT: The threshold of ABR in experiment group was elevated significantly. The latent period of each wave was pro longed significantly (P < 0.01). In experiment group, the threshold value of ABR in 2-week and 4-week group was significantly greater than that in 6-week group and 8-week group (P < 0.01). CONCLUSION Bilateral cochlears ablation surgery could elevate the threshold of ABR and latent period of each wave prolonged. The effect of hearing deprivation became apparent after surgery for 4 weeks.
