Chinese Journal of Practical Nursing 2014;30(20):65-67
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.
2.Determination of Adenosine in Chongcaoqizhi Granule by HPLC
Chinese Journal of Information on Traditional Chinese Medicine 2006;0(04):-
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.

6.Intervention effect of Dachengqi Granule on apoptosis of small intestine smooth muscle cells in rats with multiple organ dysfunction syndrome.
Chinese Journal of Integrated Traditional and Western Medicine 2014;34(5):587-591
OBJECTIVETo observe the intervention of Dachengqi Granule (DG) on the apoptosis of small intestine smooth muscle cells (SMCs) in rats with multiple organ dysfunction syndrome (MODS) and its mechanisms.
METHODSHealthy 100 adult Wistar rats were randomly divided into the control group (n =20), the MODS model group (n =40), and the DG group (n =40).E. coli suspension was peritoneally injected to rats in the model group and the DG group to establish bacterial peritonitis induced MODS model. DG at 1 mL/100 g was administered by gastrogavage to rats of the DG group, twice daily for 3 successive days. Twenty-four hours after modeling, the proximal segment of intestine was taken and stained by using terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) and immunohistochemistry. Changes of apoptosis quantity of SMCs and the expression of Bcl-2 associated X protein (Bax), B cell lymphoma/leukemia-2 (Bcl-2) and cytochrome c protein (Cyt c) in mitochondrial apoptotic signaling pathway were observed.
RESULTSCompared with the control group, the apoptosis quantity of SMCs and the expression of Bax and Cyt c protein significantly increased, and the expression of Bcl-2 protein significantly decreased in the MODS model group (P <0.01). Compared with the MODS model group, the apoptosis quantity of SMCs and the expression of Bax and Cyt c proteins significantly decreased, and the expression of Bcl-2 protein significantly increased in the DG group (allP <0.01).
CONCLUSIONDG could inhibit apoptosis of SMCs through suppressing activation of mitochondrial apoptotic signaling pathway in intestinal SMCs, thus promoting the recovery of the gastrointestinal motility function in rats with MODS.

7.Applications value of 18F-FDG PET/CT in the diagnosis and staging of prostate cancer
Chinese Journal of Urology 2011;32(10):682-684
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.

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 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.
