Objective To understand the quality of life of elders in the community of Shangqiu and analyze the affecting factors to provide a scientific evidence which could improve their quality of life.Methods The general questionnaire and World Health Organization Quality of Life Brief Evaluation From were used among 116 elders in two communities of Shangqiu.Results The quality of life of elders was in low level.The mainly factors that influencing the quality of life of elders in the community of Zhengzhou were age,education status,economic income,hobbies and interest,family relation,physical exercise.Conclusions The factors that influence the elders in community are various.To improve quality of life of elders,community workers should take relevant measures and encourage family members to participate in caring elders.

Objective To develop a RP-HPLC method to determine adenosine in Chongcaoqizhi granule. Method The separation was performed in a Kromasil ODS-1 column (250 mm?4.6 mm, 5 ?m) with a mobile phase of phosphate buffer solution (pH 6.5) - methanol (85∶15). The flow was 0.7 mL/min and the detective wavelength was set at 260 nm. Results The standard adenosine showed a good linear correlation at range of 1.016~12.192 ?g/mL. The linear regression equation and correlation coefficient (r) were Y =169339X -82318, r =0.9990, respectively. The average recovery of the loading was 98.02% and the RSD was 1.72%. The average content of adenosine was 12.45 ?g/g. Conclusion This method is accurate, reproducible and highly selective, and can be used for quality control of Chongcaoqizhi granule.

BACKGROUND:The human body pulse signal can be regarded as the convolution of the heart excitation resource signal and the pulse transfer system. The backward signal was studied more before, but the research to the forward signal is not enough.OBJECTIVE: To extract the heart excitation source signals in human pulse wave.DESIGN: A randomized controlled design.SETTING: Second Affiliated Hospital of China Medical University;Biomedical Engineering institute of Shandong University.PARTICIPANTS: Health physical-examined persons in the Second Affiliated Hospital of China Medical University on March 11,2004 were recurited. RM6240 physiological signals collection system was adopted.METHODS: The collection of pulse wave in healthy persons was input into system-analysis mode and based on the principle of blind deconvolution and feasible arithmetic, heart source signals were obtained.MAIN OUTCOME MEASURES: ①Normal human pulse wave ②The heart excitation source signals.RESULTS: In the back-half segment of cepstrum (n＞ n0), periodic impulse was in accordance with the basic human pulse frequency. There was an excitation source in the pulse wave. If high-pass filter was defined to the signal (when n0 equals to 30 in the experimentation the result will be best.), we could get the heart excitation source signal after it was filtered, F transformation, index and inverse transformation.CONCLUSION: This method is practical and feasible and will provide a basis to further analyze pulse wave.

Objective To evaluate the clinical role of F-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET) for the diagnosis and staging of prostate cancer.Methods 18F-FDG PET/CT and 99Tcm-MDP ECT whole body bone scan were both performed in 40 patients with prostate cancer proved by biopsy or surgery.We then evaluated the diagnostic value of 18F-FDG PET/CT for prostate cancer.Results Of 40 cases,17 cases were detected by 18 F-FDG PET/CT with a sensitivity of 42.5％.Of the 17 cases with lymphoma metastasis,8 cases were detected by CT while 15 cases were detected by 18F-FDG PET/CT.The sensitivity of 18F-FDG PET/CT is 88.2％.Though 18F-FDG PET/CT and 99Tcm-MDP bone scan have a similar sensitivity in detecting bone metastases,18 F-FDG PET/CT has better specificity and accuracy in detecting bone metastases than that of an 99Tcm-MDP bone scan.Conclusions Though the diagnostic value of 18F-FDG PET/CT in detecting primary focus of prostate is limited,it still has an important role in detecting lymph node metastases and bone metastases.18F-FDG PET/CT has its superiority in prostate cancer staging.It can also help clinicians to select the regimen of treatment.

Objective:To explore the influence of infusion drop speed on the efficacy of tiopronin for injection combined with sol-vents in the treatment of abnormal liver function. Methods:Totally 74 patients were randomly divided into the observation group and the control group with 37 ones in each. The infusion drop speed was 60-65 drops per minute in the observation group, and that was 30-35 drops per minute in the control group, and the infusion time was controlled in 1h in the observation group and 2h in the control group. The clinical effect and the improvement of liver function were compared between the two groups after a treatment course of 4 weeks. Results:The total effective rate of the observation group(83. 78%) was obviously higher than that in the control group(56. 76%) (P<0. 05) after the treatment, and ALT, AST and TBIL of liver function indices were improved obviously except for ALB in the two group, and the difference was statistically significant between the two groups(P<0. 05). Conclusion:Tiopronin for injection can effectively improve the clinical effect by strictly controlling the time and drop speed of infusion.

Objective To study the imaging of central pentine myelinolysis (CPM) and extrapontine myelinolysis(EPM) after liver transplantation and value of DWI. Methods Eight patients after liver transplantation with CPM and EPM were included in our study, 4 cases of female and 4 cases of male.MR examinations were performed on Philips 1.5 T MRI system. The sequences included SE T1 WI, FSE T2Wl,axial SE-EPI DWI,TR/TE 6225/118.7 ms, ETL 128, FLIP 90°, thickness 5 nun, matrix 128 ×128,b=1000 mm2/s. Results Four of B type hepatitis and cirrhosis and 1 case combined with hepatic carcinoma, 1 of C type hepatitis with cirrhosis from schistosome,2 of C type hepatitis and cirrhosis, 1 of cholangiogenic cirrhosis. MR demonstrated prolongation of T1 and T2 with a shape of butterfly, round or quadrangle on the brain stem sparing of the corticospinal tract and peripontine tissue. The lesion manifested high signal intensity both on DWI and ADC map indicating T2 effect and vasogenic edema. Follow up MR in 2 cases 2 months later showed more prolongation of T1 and T2 than the first time and the lesion manifested iso-intensity signal on DWI and high signal intensity on ADC map suggesting increased diffusivity. Abnormal signal intensities were detected on the bilateral caudate head, globus pallidus, putamen and cerebral cortex in 3 cases. Conclusion CPM should be considered when prolongation of T1 and T2 with a shape of butterfly, round or quadrangle on the brain stem, sparing of the corticospinal tract and peripontine tissue was detected for patients of pest-transplantation. When combined with other area abnormality, EPM and CPM should be considered. DWI can early and sensitively show the lesion.

External evaluation of large medical institutions is key to performance management in the medical sector,which is both a major means for the government to manage such institutions and a key guideline for their internal performance management. Based on a study on the pathways of such institutions in the UK,the USA and Japan in their external evaluation of performance,the paper summarized practices of Shanghai,Shenzhen,Zhenjiang and Beijing,in an attempt to offer references for building the external evaluation system for such institutions in China.
