Objective To survey the incidence of depression in Parkinson disease(PDD) and explore the related factors of PDD.Methods 127 patients with Parkinson disease were investigated,all of them were assessed by Hamilton Depression Rating Scale,self-designed register form and the Unified Parkinson disease scale(UPDRS).A stepwise multiple factor regression analysis was carried out to determine factors that best accounted for the occurrence of PDD.Results The overall incidence rate was 47.2%.The minor,moderate and major incidence was 14.2%,28.3% and 4.7% respectively.The regression analysis showed that factors accounted for the occurrence of PDD were gender,the severity of PD,stage of patient's motor impairment,education level and the use of dopamine agonists.Conclusion PDD seems to have a multifactorial etiology.Knowledge of risk factors related to the occurrence of PDD may help guide neurologists in the early prediction and treatment of this disease.

OBJECTIVE: To study the relationship of distortion product in cochlea with cochlear activity and hearing. METHOD: Time variances of distortion product of basilar membrane vibration in vitro guineapig cochlea were observed by laser interferometry. RESULT: Within half hour after a cochlea was isolated from a guineapig, distortion product accompanied with two-tone inhibition in cochlea, can be observed. As time passed, distortion product and two-tone inhibition effect disappeared at the same time. After that, the membrane contiune vibrating in response to the sound stimulus, but the vibration amplitude decreased obviously and continued decreasing until it disappeared completely. CONCLUSION Distortion product in cochlea is a symbol of cochlear activity which makes the membrane respond in large amplitude vibration to sound stimulus and exhibit two-tone inhibition. The former makes the hearing highly sensitive to sound stimulus, the later makes the hearing perform information abstract well.

Objective To study the histocompatibility of domestic new type nitinol alloy ventricular septal defect(VSD) occluder in order to test the feasibility for clinical application.Methods The domestic new type nitinol alloy VSD occluder was inserted into 20 healthy dogs with intravenous balanced anesthesia and tracheal intubation,assisted by animal breathing machine respiration.The dogs were given oral antibiotic and would be killed in several months after operation.According to different slaughter time(1,2,3,6 months),they were divided into 4 sections and including 5 dogs in each section.The occluder sites,the intimal coverage and the change of inflammatory cells were observed through gross anatomy,with the help of the light microscope and electron microscope.SPSS 11.0 software was used to analyze the data.Results The thickness of the endocardial enhanced with the time(P

OBJECTIVE To study the meaning of detecting the antibody of Salmonella typhi by gel technique(GEL). METHODS Minigel column technique(MGCT) and Widal reaction(WR) were used to detect the antibody among 32 suspicious typhoid and paratyphoid patients. RESULTS Among them,the titers of various kinds of antibody of S.typhi "O","H","?","?",and "?" with GEL were 1-2 orders higher than with WR.There was a significant difference in statistics. CONCLUSIONS It is convenient and fast to detected the antibody of S.typhi.And it can give important reference data for the clinic.

Objective: To evaluate the cognitive dysfunction of patients with vascular dementia (VD) Method: A cross-sectiona l investigation was done in 32 pat ients with VD and 26 normal control All of them were tested with MMSE, ADL (ac t ivity of daily life), DS (digit span), and HAMD Results: (1) M MSE result, compared with control, patient's time orientation (244?119/47 3?0 60, t=915, p

0.10). Conclusion: Donepezil is effective in treating the cognition of AD and some of the mixed dementia, but it has little effect on VD.
