An analysis is made on major issues and difficulties in the application of the performance appraisal system structure,appraisal model and appraisal outcomes.It was discovered that the performance appraisal system,if used in clinical medical technology departments in the hospital,should focus on the system itself,the appraisal process and re-improvement of the system.These three factors are key to determining whether the system is effective and efficient,and key to transforming the system into departmental and hospital performance,even into overall enhancement of hospital performance in general.

d infrastructure quality.Conclusions Raising responsiveness for special medical services will be conducive for improving the quality of non-medical services for these inpatients when they are in the hospital.

Objective To investigate the status of parenting stress in the primary care-givers of children diagnosed with autistic disorder and sum up the nursing strategies. Methods Seventy-eight primary care-givers of children diagnosed with autistic disorder were interviewed using the parenting stress index-short form (PSI-SF). Results The mean score of parenting stress was 104.08 ± 18.32, which was at a high level. The 3 subscales score from high to low:parenting anxiety(36.22 ± 8.46);disabled children (35.64 ± 6.41);parent-child interation disorder(32.01 ± 7.15). Conclusion Medical staff should pay more attertion to these care-givers in order to enhance their ability to cope with various problems in the parenting process and hence reduce the level of parenting pressure.

Medical imaging is evolving from the traditional morphologic examination to a pattern that combines morphologic and functional examinations that can reflect physiochemical changes at cellular and molecular levels. Functional imaging techniques, including CT perfusion imaging, MR diffusion weighted imaging, MR perfusion imaging and MR spectroscopy, have been drawing increasingly more attention in pathological study of the livers, pancreas, kidneys, prostates and lymph nodes, and the prospect is promising. CT & MR functional imaging combined with morphologic examination is helpful for the diagnosis and differential diagnosis of pathological lesions.

Objective To observe the effect of motor relearning program (MRP) on balance function of stroke patients.Methods Sixty stroke patients were randomly divided into the MRP group and control group with 30 cases in each group. The patients of the control group were trained with proprioceptive neuromuscular facilitation (PNF) therapy; those of the MRP group were trained with the MRP therapy. The balance function of all patients was assessed with the Fugl-Meyer Balance Function Assessment before and after training.Results After training, the scores of Fugl-Meyer Assessment of all patients increased ( P<0.05), but scores of the patients of the MRP group were significantly higher than that of the control group ( P<0.05).Conclusion The MRP training can improve the recovery of balance function of stroke patients.

Objective To investigate the prevalence of benign prostatic hyperplasia (BPH) in Beijing. Methods A cross-sectional study was performed at Beijing communities in men aged over 50 years. The International Prostate Symptom Score (IPSS) questionnaire was used to evaluate the symptoms. Transabdominal ultrasonography was used to measure prostate size and the residual urine volume(RUV). Uroflowmetry was performed to record the maximum flow(Q_(max)). One-way ANOVA was used to analysis the differences. Results 1644 subjects were enrolled and the mean age was 64. 5 years (range 50 - 93 years). The mean IPSS, prostate weight andQ_(max) were 9. 9±8. 2, (30. 8± 19.4) and (14. 7 ± 7. 5)ml/s, respectively. They had correlation with age (r=0. 388,0. 262, - 0.371). The prevalence of moderate-severe lower urinary tract symptoms (LUTS) was 50. 8% (835/1644). Prostate volume was greater than 20 ml in 69. 7%(1146/1644) of the subjects.Q_(max) was less than 15 ml/s in 53. 8% (883/1642) of the subjects. Conclusions In men age over 50 years in Beijing, there is positive correlation between LUTS, prostate size and age, and negative correlation between Q_(max) and age. The prevalence of BPH, defined as IPSS greater than 7, maxium flow rate less than 15 ml/s and prostate size greater than 20 ml, is 26. 8%(441/1644).

ObjectiveTo establish nude mouse tumor models bearing human pancreatic adenocarcinoma SW1990 cells in multiple sites at different time-points and investigate the feasibiilty of multiple tumor-bearing in these models; then the findings and detection rate of 3.0T magnetic resonance image (MRI) in subcutaneous transplanted tumors was analyzed. Methods A total of 6 BALB/C nude mice were randomized into 3 groups (2 mice per group ).At the 1st,8th,15th day,the mice were injected subcutaneously with the suspension of SW1990 cells at left axilla and right axilla and right groin in sequence.Three weeks later,all the bearing-tumor mice were performed with MRI non-contrast enhanced scanning plus Gd-DTPA enhanced scan and the subcutaneous masses were subjected to pathological analysis.ResultsAll the 6 nude mice were alive during the study and obvious mass was observed in every injected site.The tumor size was positively associated with the grwing time.There were 9 tumors which could be de.ted by noncontrast enhanced MRI scanning and one more tumor was detected by contrast enhanced scanning.2 tumors were not detected,the 2 tumors were located at subcutaneous of right groin,with the shortest growing time,and the major axis of the 2 un-detected tumors was less than 5mm.Despite the MRI findings of the transplanted masses similar to that of human pancreatic adenocarcinoma with bleeding,necrosis,they presented the characteristics of a clear rim,with pseudocapeule sign.All the 12 masses were similar with human pancreatic adenocarcinoma under light microscope.ConclusionsIt is feasible to transplant human pancreatic adenocarcinoma cell at three different subcutaneous sites (injected at three different points of time) in the nude mouse,with a minimal survival time of three weeks.However,routine 3.0T MRI cannot detect the early tumors (growing time within 1 week,major axis ＜5 mm).

Objective To investigate the correlation of blood lipid metabolism abnormity and other components of metabolic syndrome on angiocardiopathy and cerebrovascular diseases in the elderly people. Methods The clinical data of elderly people, who underwent medical examination during 1996 to 2005 in the General Hospital of PLA, were retrospectively analyzed. Based on the analysis, the co-existence of blood lipid disorders with glucose metabolic abnormity, hypertension and obesity, as well as their influence on cardio-cerebrovascular diseases were further analyzed. Results The prevalence of blood lipid metabolic disturbance was 69.6%, in which the prevalence of hyper-cholesteremia and hyper-triglyceride were 23.6% and 21.7%, respectively. The prevalence of hyper-cholesteremia accompanied by hyper-triglyceride (mixed group) was 19.3%, that of hyper-triglyceride with lower high density lipoprotein cholesterol was 5.03%, while it was 30.4% in the normal group. There was a higher risk of having the above abnormal condition in patients with type 2 diabetes mellitus (T2DM) and obesity, and they were more frequently complicated by hypertension in the hyper-triglyceride group (70.8%). When the patients with lipid metabolic disturbance were complicated by T2DM, hypertension and obesity, the prevalence of cardiovascular or cerebrovascular diseases increased. The prevalence of CHD was higher in the patients with hyper-cholesteremia and hypertension or diabetes, and incidence of both CHD and CVD was higher in the patients with hyper-triglyceride and either one of hypertension, diabetes or obesity. Conclusion There is high prevalence of lipid metabolic disturbance (more than two thirds) and other components of metabolic syndrome, and high risk of suffering from cardiovascular or cerebrovascular diseases in elderly people. The aging patients with hyper-triglyceride are vulnerable to cardiovascular or cerebrovascular diseases, and more attention should be paid in clinical practice in future.

Objective To analyze the significance of the waistline (WC), body mass index (BMI) and hyperinsulinaemia (HIns) on evaluating the metabolic syndrome. Methods The data of routine clinical examination were collected from the mid-aged and senile individuals (middle-senile group) who received oral glucose tolerance test (OGTT) for diabetes screening, and from a group of subjects who received annual OGTT for diabetes screening (mature group). Data were collected by a specialized person, input into a special computer database, and then analyzed with SAS 5.0 software by specialized staffs. Abnormal WC and BMI were determined according to IDF and CDS criteria. HIns was determined if fasting insulin (FIns) ≥15mU/L and 2-hour insulin after glucose burdening (2hPIns) ≥80mU/L. Results In the middle-senile group, the abnormality frequencies of WC and HIns as well as overall insulin level were obviously higher than that in the mature young group. The abnormality frequency of BMI was higher in mature young group. A higher detection rate of HIns existed in intolerance glucose test (IGT) and normal glucose test (NGT). The coincidence of WC and BMI diagnostic criteria were 77.5% and 74.3%, respectively, on evaluating with or without obesity in the middle-senile group and mature young group. When only WC criterion was used for evaluating the existence of insulin resistance, there would be 28.2% of missed diagnosis rate for MS patients. Conclusion WC, BMI and HIns are all risk factors for abnormal glucose metabolism, hypertension and dyslipidemia. There is different prevalence among different populations. The combination of WC, BMI and HIns might be more helpful for identifying MS at early stage.
