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.

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.

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 analyze the flow tendency of elderly patients,create a better mechanism to help guide elderly patients to form a good order in seeking medical care,and consequently improve the resource operational efficiency in medical service.Methods Analyzing the data by the descriptive,χ2 test and logistic regression of SPSS 20.0.Results Elderly patients prefer community health service centers and tertiary hospitals;of those visiting tertiary hospitals,nearly 30% seek medical advice for common chronic diseases.Main influencing factors for patient flow are medical insurance coverage and education. They tend not to embrace the two-way referral service,due to such factors of inconvenient process and defective mechanisms.Conclusion Transition from medical demand management to medical supply management.Such factors as quality cost,expense cost,time cost,and public opinion cost should be used to replace and weaken their mindset of the medical hierarchy,and embrace the concept of “seeking medical advice by grades”,thus improving the utilization of medical resources,and optimizing medical service accesibility.

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).

Haemophilus influenzae (Hi) is a pathogen exclusively found in humans. It causes a wide range of infections from the upper respiratory tract to serious invasive diseases. Such as pneumonia, septicemia and meningitis. Strains of Hi are usually classif ied into six serotypes a to f and nontypeable H. influenzae (NTHI) according to the antigenicities and compositions of their polysaccharide capsules. Hib was a common cause of serious infections in younger children. The polysaccharide-protein conjugate vaccines against Hib had almost eliminated H. influenzae as a cause of pediatric meningitis. However, NTHI remains an important pathogen, particularly in children and the elderly. Efforts to understand and control NTHI disease have been hampered by the diversity of these bacteria. This review introduced the study progress about pathogenic mechanism of NTHI. In order to provide the help for development of vaccine, clinic treatment and prevent the occurrence of diseases causing by NTHI.

Objective To assess the association of obesity, serum lipid levels and insulin resistance with leptin in Nanjing population. Methods One hundred and eighty eight subjects aged 22～81 years in Nanjing were divided into three groups according to BMI and dignosis criteria of diabetes: normal group, obese group and diabetes group. Their weight, height, waist, abdomen and hip circumferences were measured. Total cholesterol, triglycerides, low density lipoprotein cholesterol, high density lipoprotein cholesterol, apoA, apoB, fasting plasma glucose (FPG), true insulin (TI), immunoreactive insulin (IRI) and leptin were also measured. ISI 1=1/(FPG?TI) and ISI 2=1/(FPG?IRI) as insulin sensitivity indexes were used to analyse the relation between leptin and insulin resistance. Results Fasting serum leptin level was associated with sex (four fold as high in women as that in men). BMI was the second strongest determinant of leptin. Leptin was positively correlated with TI (r=0.32, P
