In order to evaluate the quality of life and affecting risk factors for the elderly populations, cluster sampling method was used to investigate 1731 elderly individuals at Shimenerlu Community in Shanghai. The results showed that the average quality of life of the participants was above medium level, and most elderly demonstrated good quality of life. Moreover, 1536 elderly individuals (88.9%) developed at least one chronic disease, and the incidence of depression was up to 17. 2%. Affecting factors of quality of life included daily life capability, severity of disease, age, depression symptom, marriage, community activities, care provider, gender, number of disease, diabetes, hobby, income, expense, family support, and living conditions. No correlation with education, career, health insurance, and partner's disease was found. Those data suggest that community heahhcare should pay more attention to the management of chronic diseases and mental health, the development of family resources, and the improvement of hobbies and social activities in the elderly populations.

Objective It aims to investigate prevalence of depressive symptoms among the elderly in community and to understand their related social factors. Methods Four neighborhood committees were randomly selected with cluster sampling as survey sites. Enrolled residents at age of 60 to 89 years were evaluated with a general background inventory and a geriatric depression scale(GDS). All the data were input to a microcomputer and were analyzed for its relevant factors with SPSS13. 0 software by multivariate logistic regression model. Results Totally, 1731 elderly people in the community were interviewed and rated with the inventory and scale mentioned above, and depressive symptoms were found in 297 of them, with prevalence of 17. 2 percent. Multivariate logistic regression analysis showed that there were seven factors associated to their depressive symptoms in the elderly, including family expenditure, housing condition, medical condition, familial support, hobbies in spare-time, ability to take care of oneself and participation to social activities. Conclusions A few social factors, such as living alone, insufficient income for family expenditure, disability of self care-taking, lack of hobby in spare-time, less participation to social activities, lack of familial support and severe chronic diseases by serf-evaluation, are all associated with depressive symptoms in the elderly.

The aim of this study was to investigate the feasibility of anterior segment optical coherence tomography to assess the anterior segment morphology of hyperopia in school-aged children. 320 eyes of 160 school-aged children, 6-12 years of age, were examined with anterior segment optical coherence tomography and were divided into four groups according to the cycloplegic spherical equivalence of refractive error. The mentioned four groups were: emmetropia group, low hyperopia group, moderate hyperopia group and high hyperopia group. The measurements of central corneal thickness, anterior chamber depth, angle opening distance, trabecular iris space area and scleral angle were compared in pairs among objects in the four groups. The results showed that high hyperopia and moderate hyperopia had shallower anterior chamber depth and narrower anterior chamber angle compared to those in emmetropia group. The study also showed that anterior segment optical coherence tomography as a non-contact technology could become a new technology for accessing the anterior segment morphology of hyperopia in school-aged children.

Objective: To investigate effect of curcumin on serum gelatinases levels in patients with unstable angina pectoris（UAP）. Methods： A total of 80 UAP patients admitted from January 2010 to September 2010 were enrolled and randomly divided into curcumin treatment group (n=40) and routine treatment control group (n=40). Serum levels of gelatinases [contain matrix metalloproteinase（MMP）-2 and -9) of the two groups were measured before and 30d after treatment. Results：Compared with before treatment , after treatment, serum gelatinases levels significantly decreased [MMP-2：（52.64±6.77）ng/ml vs. （32.65±1.67）ng/ml，MMP-9：（56.75±7.34）ng/ml vs.（35±1.88）ng/ml ] (P<0.01) in curcumin treatment group (P<0.01), and they were significantly lower than those of routine treatment control group [MMP-2：（32.65±1.67）ng/ml vs.（37.78±2.76）ng/ml，MMP-9：（35±1.88）ng/ml vs.（40.23±1.95）ng/ml ] , P<0.05 all. Conclusion：Curcumin could decrease serum levels of gelatinases in patients with unstable angina pectoris, and possesses effect of stabilization coronary artery plaque.

Ischemic cerebrovascular disease(ICVD) is temporary or permanent reduction of blood flow of the main arteries of the brain caused by cerebral transient,sudden,reversible neurological dysfunction.Timely recovery of blood supply to the brain is the most important way to save the patient's life,but at the same time gave restore blood perfusion brain tissue organs brought new damage,which is cerebeal ischemia reperfusion injury(CIRI).How to build an ideal,efficient,easy to operate brain ischemia-reperfusion injury in animal models to simulate the clinical study,and how to improve and innovate this model by researchers in recent years were reviewed in this article.

Objective:To observe the accuracy of electronic method(EM), handing method(HM) and X-raying method(X-RM) in measuring root canal working length. Methods:Total 31 root canal in vivo were measured with HM, X-RM and EM(by the electronic apical locators-Root ZX and Raypex-5 respectively), and the data were compared with the actual root canal working lengths which were obtained from the sectional view's constrictions of the extracted teeth by magnifying glass. Results:Accuracy of working length measured by Raypex-5 was 93.55%, Root ZX was 87.10%, HM was 35.48%, and X-RM was 48.39%. Significantly statistical differences (P

Cryoablation,a kind of physical ablation for tumor treatment,is minimally invasive,safe and effective.Studies suggest that cryoablation can not only kill tumor cells directly,but also the anti-tumor immune response triggered by cryoablation plays an important role in inhibiting the growth of local tumors and eliminating the residual tumor cells.

Ischemic cardiomyopathy (ICM) is due to coronary atherosclerosis cause long-term myocardial ischemia, make myocardial fibrosis diffuse, produce similar clinical syndrome like idiopathic dilated cardiomyopathy, which is one of a common clinical disease and causes increasing hazards to human health.Timely recovery of blood perfusion and coronary artery recanalization is one of the effective methods of treatment.However, it brings new damage while tissues and organs receive reperfusion, which is myocardial ischemia-reperfusion injury.In this paper, the current research progress in medicine myocardial ischemia-reperfusion injury and how to build a simple and efficient experimental animal models to mimic human myocardial ischemia-reperfusion injury were reviewed.

Objective To investigate the diagnosis and therapeutic methods of primary tumors of duodenum(PTD).Methods Clinical data of 86 patients with primary duodenal tumors who were hospitalized in the First Affiliated Hospital of China Medical University during 26 years were analyzed retrospectively.Of all the tumors,18 cases were benign tumors and 68 cases were malignant tumors.Results The clinical(manifestations) were symptoms of bile duct obstruction,GI and nonspecific symptoms,and signs included(fever),anemia and weight loss.The correct preoperative diagnostic rate by auxiliary examinations were:(duodenal) endoscopy 92%,air barium double radiography 89%,MRCP 85%,BUS 33%,CT 51%,MRI 75%,and duodenal endoscopy combined with air barium double radiography were 95%.Tumors were mostly located in the descending portion of duodenum(71 cases).Eighteen cases of benign PTDs were resected(completely) with a 5-year survival of 92.3%.Among the 68 maligant PTD cases,35 cases underwent(pancreatoduodenectomy),and 8 cases received segmental duodenectomy,with a resection rate of 63.2% and the 5-year survival rate of 31.0%.The remaining 25 cases,in which the tumors were unresectable,were treated by bypass operations,the 5-year survival rate was 0%.Conclusions Patients with PTD usually lack specific symptoms and signs,but combination of endoscopy,GI air barium double radiography and other(examinations) can improve the preoperative positive diagnostic rate.Segmental duodenectomy and simple tumor resection are curable for primary benign tumors of duodenum;while for primary malignant tumors of(duodenum),the therapy of choice should be pancreatoduodenectomy.
