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 understand drug use in children with common cold through comments on prescription and drug analysis,and to provide theoretical basis for standardizing medical treatment and promoting rational drug use.Methods A retrospective survey method was applied.Prescriptions of common cold in the department of pediatrics from Oct.to Dec.2015 were reviewed,and Excel 2013 was used for statistical analysis.Rationality of drug use was evaluated based onhospital prescription review management specification (try out),instructions and consensus of related experts at home and abroad.Results The utilization rate of antibacterial drugs was 93.4％in children with common cold of our hospital,utilization rate of antiviral drugs was 59.7％,utilization rate of compound cold medicine was 96.4％,and the rate of combined utilization of more than two kinds of compound medicine was 65.7％.Excessive medicine for common cold existed and abuse of cold medicine,antimicrobial and antiviral drug,irational drug combination in this hospital.Conclusion Clinical doctors lack cognition to common cold and cold medicines.Hospital pharmacy department should take effective pharmaceutical interventions to improve the level of rational drug use.

Objective To evaluate the role of mierosurgery in surgical treatment to urethrocutaneous fistula after urethroplasty in hypospadias and improve surgical results.Methods From 1999 to 2006,44 urethrocutaneous fistulae (more than 3mm in diameter) after urethroplasty for hypospadias in 33 patients were repaired with different skin flaps.For example,Thiersch technique,urthroplasty,etc.Microsurgical tech- nique was employed in every case.Results The success rates of different procedure were 84.8% (28/33) for Thiersch technique,100% (11/11) for urethroplasty respectively.The total success rate was 88.6%(39/ 44).Conclusion It's just application of skin flap for repairing of big or complex urinary fistula after hypos- padias surgery.The application of microsurgical technique can increase success rate.It is necessary to excise scar and partial urethra for hypospadias fistula combined with urethral structures,cicatricial eontracture and in- curvation of penis.Rich blood-supply,low tension and atraumatic technique are all very important to improve surgery success rates of urinary,fistula after hypospadias repair.

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 provide reference for investigating the disease burden of diabetic patients and promoting rational drug use. METHODS:Open-ended questionnaires were adopted to survey the willingness to pay(WTP)of some diabetic patients in Sichuan Provincial People’s Hospital and collect the data about personal information,health status,the affordability of disease and WTP,the data was sorted with Excel (version 2013) software by two operators and analyzed with SPSS 17.0 software by step-wise multiple linear regression to explore the influential factors of WTP values. RESULTS:Totally 120 questionnaires were sent out and 106 were effectively received with effective rate of 88.3%. The average age of respondents was (59.9 ± 13.9) years old,the average body mass index (BMI) of respondents was (24.5 ± 0.5) kg/m2,the highest proportion of monthly diabetes fees was no more than 300 yuan,followed by more than 300-500 yuan and more than 500-1 000 yuan;the awareness rates of fasting plasma glucose (FPG),2 h postprandial blood glucose (2 h PG) and glycated hemoglobin (HbA1c) were 95.3%,86.8% and 68.9%,respectively;and patients with more than 2 complications accounted for 29.5%. The WTP values of respondents to the complete recovery of HbA1c,FPG and 2 h PG were 1 604.1,1 617.9 and 1 683.7 yuan/month,the median values were 1 000 yuan/month;the WTP values of respondents to the 10% recovery were 867.4,908.5 and 877.9 yuan/month,the median values were 500,575 and 510 yuan/month,respectively. The influential factors with positive effects and significant differences on WTP values in step-wise multiple linear regression were total annual household income,complications,hospital experience,family history of di-abetes,diabetes mental status and cost of diabetes in the past months;those with negative effects and significant differences on WTP values were age,FPG level and education level. CONCLUSIONS:Diabetic patients,particularly,with peripheral neuropa-thy,high blood lipids or diabetic foot have higher WTP value,which shows they hole heavier mental burden and disease burden than others. Patients recovered 10% percent were closer to actual treatment state,which better show the influential factors of WTP values actually,and patients with a family history of diabetes,depressed mood,higher fees in the average monthly cost,and hospi-tal patients have higher WTP values.

Objective To evaluate the clinical application of CT perfusion imaging (CTPI) and CT subtraction angiography (CTSA) in the diagnosis of acute ischemic cerebrovascular disease (AICVD). Methods 24 cases with AICVD onset within 24 hours were examined with regular CT, CTPI and CTSA. Some of them took CTPI, MRI, MRA, DSA, SPECT by follow up examinations. Results In 24 cases 11 had regular CT negative results after onset of stroke 3～6 hours in 6 cases,6～12 hours in 3 cases,12～24 hours in 2 cases. Ten cases of them were confirmed by CTPI as having ischemic lesions, 2 cases had middle cerebral artery occlusion (MCAO), and 1 had transient ischemic attack (TIA) with CTPI negative. In 24 cases 13 had regular CT positive rseults, 9 cases had ischemic lesions larger in CTPI than in regular CT,1 case had MCAO and 1 case had internal carotid artery occlusion(ICAO). There were 4 cases with ischemic lesions on regular CT almost having the same range as that of lacunar infarction in CTPI. The peak value of time(PT), mean transit time(MTT), relative flow (RF) in all 24 cases were found obviously changed. The side of ischemic lesion as compared with the opposite side, and the core of ischemic lesion as compared with peripheral zone were found changed significantly ( P
