Objective:To verify the association between social determinants and the quality of life ( QoL) among the elderly in Beijing .Methods:A questionnaire household survey was conducted and 1 685 over 60 dwellers in Beijing were interviewed .The EQ-5D scale was used to measure the elderly ’ s QoL and Time Trade-off model was used to calculate the EQ-5D index.Multiple linear regression and Logistic regression were employed to analyze the association between social determinants and the QoL .Results:There was no statistical significant difference in the QoL between the urban and the rural residents ( P>0 .05 ) .The elderly with higher education level and income or married tended to have higher overall QoL scoresand better performance of five dimensions of the QoL (P<0.05).Conclusion:More policies should be focused on the elderly with lower social determinants in both urban and rural areas in Beijing .

Objective To analyze the relationship between serum intermedin ( IMD ) , CystatinC ( CysC ) and fibro-blast growth factor23(FGF23) with hypertensive left ventricular hypertrophy (HLVH). Methods Serum IMD,Cy-sC and FGF23 levels of 30 patients with essential hypertension(EH group),30 hypertensions with LVH(HLVH group)and 30 healthy subjects(control group)were detected by enzyme-linked immunosorbent assay(ELISA). All the subjects did UCG for LVMI. Results LVMI and serum IMD,CysC,FGF23 levels were significantly higher in EH group than in control(P<0. 05),higher in HLVH group than in EH and control groups(P<0. 05). In the pa-tients with hypertension LVMI and serum IMD,CysC,FGF23 levels were increasing with increased blood pressure levels. LVMI level was positively correlated with serum IMD,CysC and FGF23 levels(r=0. 769,0. 517,0. 700;P<0. 01). Line to LVMI level as the dependent variable,multiple stepwise regression analysis showed that:systolic blood pressure( SBP) ,IMD,CysC,homocysteine( Hcy) ,FGF23 entered regression equation. They were independent risk factors for LVMI. Conclusion Serum IMD, CysC and FGF23 levels are closely associated with EH and HLVH. They may participate in the development of EH and affect the process of HLVH. Combined-detection of ser-um IMD,CysC and FGF23 can be used as a reference index for the condition and prognosis of HLVH.

Objective:To study the status quo of National Essential Medicine System ( NEMS) in village clinics of a province in western China. Methods:Individual in-depth interview was carried out with village doctors and their managers of a province in western China, to understand the subsidies of zero-markup rate, compensations for general medical fees, and status quo of NEMS assessment mechanism and its impacts on prescribing behavior of village doc-tors. Results:In the surveyed area, the intervention of NEMS has not achieved the desired objectives: the prescri-bing behavior of village doctors has not changed significantly;general medical fee system has failed to achieve reason-able compensations;and the assessment mechanism done by village doctor managers has been a mere formality. Con-clusions and Suggestions:To ensure the feasibility, effectiveness and sustainability of the intervention, the area poli-cymakers should take into full consideration the special nature of village doctors.

Objective To investigate the effect of complete revascularization strategy on the prognosis of elderly patients suffering from acute ST-segment elevated myocardial infarction(STEMI)complicated with multivessel disease(MVD). Methods A total of 390 elderly patients(over 60 years old)suffering from acute STEMI with MVD treated by clinical revascularization administration were enrolled for the study and divided into complete revascularization group(CR group,n=139)and non-complete revascularization group(NCR group,n=251). The effect of complete re-vascularization strategy on the prognosis was then analyzed by COX regression analysis. Results Compared with the NCR group,the patients of the CR group are younger and with a higher ratio of old myocardial infarction ,as well as the average number of stents ,and the mean value of total stent length is larger. The application of calcium channel blocker for post-operation patients is rarer as well. No significant difference can be found between the two groups on the ratio of post-operation all-cause mortality,cardiac mortality,nonfatal myocardial infarction,unplanned repeat revas-cularization. Multivariate COX analysis showed that the complete revascularization had no obvious difference on the prognosis of these patients be-tween the two groups. Conclusion There is individual diversity in the revascularization strategy choosing for elderly patients of acute STEMI alongside MVD;however,the prognosis is not significantly improved.

Objective To study the influence of madopar for 5-HT in platelet of Parkinson's disease patients.Methods To observe 5-HT in platelet of 35 PD cases in our hospital who take Madopar in one year.At the same time,to observe the mental symptoms change of every case before and after the treatment.Result Madopar can significantly lower the 5-HT of platelet in one year treatment,and HAMD score results show that Madopar significantly higher before treatment.Conclusion Madopar can damage serotonin neurons in the brain,which may enhance the patients with depressive symptoms.

Objective:To understand the current status of health-related hardiness among breast cancer patients undergoing radiotherapy and to analyze its influencing factors, and to provide evidence for the development of psychosocial care programs for breast cancer patients undergoing radiotherapy.Methods:A total of 126 postoperative breast cancer patients undergoing radiotherapy were selected from the First Affiliated Hospital of Dalian Medical University from January to September 2018. The self-designed general data questionnaire and Health-related Hardiness Scale (HRHS) were used to analyze the current status and the influencing factors of health-related hardiness among patients.Results:The overall score of health-related hardiness among breast cancer patients undergoing radiotherapy was 127.61±20.19, which was located at the low medium level. There were significant differences in the scores of patients of different ages, education background, marital status, fertility status, children status, family history, religion, family income, and medical insurance forms ( t value was -3.800-8.128, F value was 8.906-274.271 P<0.01). The regression analysis showed that the influencing factors of health-related hardiness were age, family income, marital status, education background, family history, and religion. The degree of the dependent variable was 89.4%. Conclusions:Breast cancer patients undergoing radiotherapy have a low medium level of health-related hardiness, and are affected by age, family income, marital status, education background, family history, and religion.

Objective To discusse the expression and clinic opathologic significance of vascular endothelial growth factor(VEGF) and microvessel density(MVD) in primary liver cancer,an immunohistochemical staining.Methods The expressions of VEGF and Ⅷ factor were determined in 60 selected operation specimen from patients with primary liver carcinoma.Results It showed that the positive expression rate of VEGF in primary liver cancer was 63.3%,the MVD was (30.76?11.56).Among them,the MVD in positive VEGF expression was (46.37?15.85),and the MVD in negative expression was (18.97?8.68),there were great statistical difference between them(P0.05).Conclusion This study indicates that VEGF can facilitate the formation of microvessel of the tumor and has correlation with the growth,infiltration and metastasis of primary liver cancer.
