Dry age-related macular degeneration(AMD)is a prevalent form of irreversible blindness worldwide in the elderly population with an increasing incidence in China.It is found that some dry AMD will develop to wet AMD and therefore damage visual function.Pathogenesis of AMD is below understand now,but it is thought to be related to the light-induced ocular damage,oxidative stress response,extracellular disposition and immunology.Up to now,effective and safe prevention and treatment methods of AMD are still studying,especially wet AMD,but the concern on dry AMD is not enough.Some basic and clinical pharmaceutics researches on AMD include antioxidants,anti-extracellular disposition drugs and anti-inflammatory agents.With the rise of aging population,we should pay special attention to the research on pathogenesis,diagnosis and treatment of dry AMD.

Objective To investigate the characteristics of early changes in serum IL-17 and IFN-γ levels in elderly patients with acute myocardial infarction (AMI).Methods 70 hospitalized elderly patients with AMI and 35 healthy people were selected.Serum level of interleukin-17 (IL 17) and interferon-γ (IFN-γ) were assayed by enzyme linked immunosorbent assay (ELISA).Results Serum levels of IL17 and IFN-γ showed increasing trends in elderly patients with AMI as compared with that in control group,but there were no significant differences between the two group [(35.73 30.28) pg/ml vs.(28.70±17.12) pg/ml,(15.29±14.64) pg/ml vs.(11.38±10.10) pg/ml,t=0.144 and 0.138,P=0.365 and 0.377].There were correlations between serum IL-17 and IFN γ levels in patients with AMI and controls(r=0.936 and 0.989,both P=0.00).Serum levels of IL-17 or IFN-γhad no significant differences between AMI patients with well and poor prognosis [(35.43± 34.36) ng/L vs.(36.11±30.16) ng/L,(13.90±13.98) ng/L vs.(15.99±14.14) ng/L,U=0.266 and 0.166,P=0.687 and 0.668].Conclusions Serum IL-17 level has an increasing trend in AMI patients within 24h,but has no statistical significant.Serum IL 17 level has a significantly positively correlation with serum IFN γ level in the elderly,but serum levels of IL-17 or IFN γ have no significant correlations with short term prognosis in elderly patients with AMI.

Objective To explore the changes of index of heart function and major cardiovascular events (nonfatal myocardial infarction, stroke, and cardiovascular death) to H-type hypertension patients with left ventricular hypertrophy caused by Tianma Gouteng Decoction.Methods 126 H-type hypertension patients with left ventricular hypertrophy from January 2014 to May 2014 in our hospital were divided into observation group and control group,63 cases in each group.Control group was treated with conventional western medicine, observation group was treated with Tianma Gouteng Decoction on the basis of control group.The levels of plasma homocysteine (Hcy), left ventricular ejection fraction (LVEF),the E/A, and the incidence of major cardiovascular events were recorded and compared between the two groups.Results Compared with pre-treatment, the levels of Hcy in the two groups were significantly decreased(P<0.05), and the effect of observation group was better (P<0.05).After the treatment, the E/A and LVEF of the two groups were significantly improved (P<0.05); the E/A ratio and LVEF in observation group were significantly higher than those in control group (P<0.05).The incidence of major cardiovascular events in observation group was significantly lower than that in control group (6.35%VS 19.05%,P<0.05).Conclusion Tianma Gouteng Decoction can significantly reduce the Hcy of patients who get H-type hypertension, improve diastolic and systolic function and lower the occurrence of major cardiovascular events.

Objective To determine the effects of Sodium Nitroprusside ( SNP) , superoxide dismutase ( SOD) and catalase ( CAT ) on the expression of catalytic subunit of the DNA-dependent protein kinase ( DNA-PKcs ) and Ku70/80 heterodimer in cardiomycyte H9C2, as well as their expression in the myocardial tissues of SD rats . Methods H9C2 cells were co-cultured with SNP at concentreations of 10, 20 and 40 mmol/L for 6 hours, SD rats were injected with normal saline , SNP, SNP+SOD, SNP+CAT or SNP+SOD+CAT.Western blot and immuno-histochemistry assay were used to examine DNA-PKcs and Ku70/80 protein expression respectively .Results The expression of DNA-PKcs and Ku70/80 increased in H9C2 cells co-cultured with SNP when compared with control group, but they were be decreased when treated with SOD or/and CAT.The expression of DNA-Pkcs and Ku70/80 in myocardial tissues of experimental groups were higher than the control .Conclusions Radical scavengers may play a role as a protective effect for sodium nitroprusside related injury in cardiac myocytes .

Objective To observe and analyse the application effect and value of problem based learning (PBL) combined evidence-based learning (EBL) in emergency medicine clinical teaching.Methods A total of 53 clinical medicine students were selected.The combined teaching method was applied in emergency clinical teaching.After the end of the teaching,the teaching effectiveness survey and theory test of the combined teaching group was performed,and the theory test scores was compared with the traditional teaching group.Results The combined teaching method could stimulate learning enthusiasm,improve learning efficiency,the abilities of selfstudy,literature retrieval,and the ability to analyze and solve problems.77.4％ of students thought this new teaching method had good application value in clinical teaching.Furthermore,the excellent rate of the theory test scores combined teaching group was better than traditional teaching group (41.5％ vs 15.6％,x2 =7.868,P =0.007).Conclusions The PBL joint EBL pedagogy can overcome diadvantages of tradional teaching and provide higher interest,ability of self-study as well as higher teaching quality of the medical students.It will be worth to spread in medical clinical teaching.
