Ocular neovascularization,abnormal formation of new vessels from pre-existing capillaries,is a special pathologic change of many ocular diseases,including diabetic retinopathy and retinopathy of prematurity,etc..Ocular neovascular diseases comprise the common causes of blindness in millions of people.Recent studies showed that kringle domains from many endogenous proteins inhibit the proliferation and migration of endothelial cells in vitro and neovascular formation in vivo.Hence kringle domain with conservative structure has been considered as a potential inhibitor of neovascularization.The update studies on antiangiogenic kringle domains and its inhibition on ocular neovascularization were summarized.

0.05) respectively in groupC1-C4,while in groups T1-T5,the rates were 21%,28%,36%,40%,37.5% ( P 0.05).However,the differentiation rate of MSCs increased probably with the incubation time prolonged.During the procedure of MSCs differentiation,the expression pattern of some genes such as GATA4 and cTNT may make some difference.

Objective:To observe the tansdifferentiation of bone marrow mesenchymal stem cells(MSCs) into cardiomyocyte in a coculture system with cardiomyocytes.Methods:Newly born Wistar Rats' cardiomyocytes were isolated and cultured and the cells were labeled with DAPI.Prepared MSCs were planted into the cardiomyocytes dishes to establish a co-culture system.Supernatant liquid of the cardiomyocytes or fibroblast was added the MSCs(non-labeled) dishes as the control. After one week of coculture,fluorescence microscope observation and immunocytochemical staining with cTnT was performed to evaluate the phenotype changes in non-labeled MSCs.Results:MSCs and cardiomyocytes were connect with each other by net in culture plate after a few days of coculture;some non-labeled cells were positively stained by cTnT antibody while the MSCs cultured with cardiomyocytes or fibroblast supernatant liquid were stained negatively.Conclusion:To obtain cardiomyocyte phenotype in vitro,direct contact of MSCs with cardiomyocytes is essential.The signaling molecules induce MSCs' transformation into cardiomyocytes are likely some membrane proteins on the surface of cardiomyocytes.

This paper argues that the core idea of evidence-based medicine is to “follow the evidence”,whose essence is a model of clinical medical service,and a guiding ideology for the clinical practice.It has become a proper noun nowadays.The wording “evidence-based medicine teaching method”needs discussion, because “evidence-based medicine” and “teaching method” are lack of logical internal relations in concept.The teaching method of scientific sense has its own characteristics and requirements.To name a teaching method,it is necessary to define its peculiar connotation in teaching method,with specific procedures and steps to form a complete set of scientific method of teaching.

The research methods, such as philology of medicine history and comparison between tradition and modern and so on were adopted in this article to study the acupuncture-moxibustion development after western medicine spreading to the East in Japan and its main transition under the impact of western medicine. The results showed that from Meiji to Showa period, under the influence of western medicine, the transition of Japanese acupuncture-moxibustion mainly embodied in following three aspects, incuinng acupuncture works absorbing western medicine knowledge, applying experiment measures to explore acupuncture principle and launching acupuncture teaching in accordance with Europe and America academy educational pattern. The changes on acupuncture works, teaching materials and methods of researching and teaching have triggered the transition and transformation of Japanese acupuncture-moxibustion from tradition to modern.

Percutaneous pulmonary valve implantation (PPVI) is an exciting growing field in cardiovascular medicine.With the sophisticated improvement of biomedical engineering,development of PPVI offers people a new way of less invasive techniques to treat these groups of patients with pulmonary valvular regurgitation over the past several years.New stent designs and operative and interventional hybrid approaches are under investigation.This nonsurgical approach has been proven to be feasible and holdpromise,although many obstacles still exist.At the present time,PPVI has been widely used in clinical in the United States and European countries,but in our country,only a small number of cases reports have been published.With wider application and development of PPVI,cumulative experiences and long-term follow-up of PPVI therapies,better criteria will be established for patient election.Complications will be reduced and safer and more effective treatment results will be achieved.PPVI therapies will be applied to a larger subset of patients and become an important alternative to future conventional pulmonary valve replacement.

Objective: To understand the cognition status for risk factors and early symptoms of stroke via face to face questionnaire survey in 336 in-hospital patients with atrial ifbrillation (AF).
Methods: A face to face questionnaire survey was conducted by uniformly trained investigators in 336 AF patients who were admitted in our hospital more than 3 days from 2014-04-01 to 2014-10-01.
Results: There were 300/336 AF patients ifnished the questionnaire and among them 131 (43.7%) patients know that AF may increase the risk of stroke and 169 (56.3%) patients unknown or uncertain. There were 41.3%-79.3% patients having cognition for early symptoms of stroke and only 25.3% (76/300) patients may identify all 5 early signs of stroke.
Conclusion: In our research, AF patients had poor cognition for the risk and early signs of stroke. Medical professional should intensify the propaganda and education for stroke prevention.

ObjectiveTo test the susceptibilities of Candida albicans to 5 antifungal agents including methylrosanilinium chloride and to estimate their relationship with the genotypes of C.albicans.MethodsThe susceptibilitiesof 67C.albicansisolatestomethylrosaniliniumchloride, fluconazole, amphotericinB,itraconazole and ketoconazole were determined by using a broth dilution method as described in the National Committee for Clinical Laboratory Standards(NCCLS) document M27-A2.DNA was extracted from the C.albicans isolates and subjected to the amplification of 25S ribosomal DNA(rDNA) introns by PCR.The C.albicans isolates were divided into A,B and C genotypes according to the amplicons.The relationship was analyzed statistically by exact probability test between the genotypes and antifungal susceptibility of C.albicans.ResultsOf the 67 C.albicans isolates,8.96％ were resistant to fluconazole,2.98％ to itraconazole,1.49％ to ketoconazole,and no resistance to amphotericin B was observed.The minimum inhibitory concentration (MIC) of methylrosanilinium chloride varied from 0.125 to 4 mg/L.Statistical analysis revealed no significant correlation between the genotypes and autifungal susceptibilities of C.albicans(all P ＞ 0.05).Conclusions More attention should be given to the increasing resistance to fluconazole and itraconazole in some isolates of C.albicans as well as to the favorable antifungal activity of methylrosanilinium chloride.The antifungal resistance shows no apparent correlation to the genotypes of C.albicans.

Objective To investigate the changes of cesarean section rate and indications in different level hospitals of different areas in China during 2000 to 2009. Methods Literatures published in Chinese journals on variation of cesarean section rate and indications from 2000 to 2009 were analyzed. Cochran-Armitage test was used to analyze the trend. The differences of cesarean section rate between different areas or different level hospitals were analyzed by chi-square test.Results Forty-nine papers were enrolled in this study.Cesarean section rate had risen from 2000 (32.1％,10 353/32 258) to 2009 (52.5％,3674/6992)(Z=-20.8267,P＜0.01).During 2000 to 2008,the average cesarean section rate of level one grade A hospital was 45.7％ (3754/8214),which was higher than 34.5％(25 015/72 507) in level three grade A hospital and 32.3％(28 140/87 121) in level two grade B hospital (P＜0.05,respectively).Except for level three grade A hospital,cesarean section rate had risen in the other two level hospitals during 2003 to 2008. The average cesarean section rate was 58.6％ (4982/8502) in northeast area during 2000 to 2007,which was higher than that of other areas (P＜0.01); and the average cesarean section rate was 27.5％ (12 264/44 595) in central China and 33.0％ (23 239/70 421) in southern China,which were lower than that of other areas (P＜ 0.01 ). Social factor,instead of dystocia,became the most important indication for cesarean section,and its proportion kept rising annually,from 11.3％ (1170/10 353) in 2000 to 27.1％(2094/7726) in 2008 and remained above 20.0％(5159/24 691) since 2004.The proportion of scar uterus rose from 6.7％(694/10 353) in 2000 to 12.5％ (459/3674) in 2009. Conclusions Cesarean section rate rises fast and its major indications had changed in China. It is suggested that special method should be taken to control the current situation.

Objective To summarize the treatment experience of acute cerebral infarction (ACI)combined with deep venous thrombosis (DVT) of lower extremities in the elderly. Methods Thirty cases of elder patients with ACI combined with DVT (ACI group) were enrolled in this study, and 31 cases of elder patients with DVT were served as control group. All the patients were immobilized for 3 days and treated with low molecular heparin calcium (100 IU/kg,Q12 hX14 d). On the tenth day,warfarin was used and INR was controlled in 2.0～2.5. Low molecular dextran was infused intravenously per day for 14 days (500mg/d). Results Edema in the lower limbs of patients were apparently reduced. 4 eases had cerebral hemorrhage in ACI group, and none in the control group.Hemorrhage occured from 3 to 7 days during the treatment with low molecular heparin calcium. One of the patient died of massive intraeranial hemorrhage with lung infection. Conclnsions It should be more careful to use the low molecular heparin to treat the elder patients older than 80 years old with ACI combined with DVT.
