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.

The statistical data on Traditional Chinese Medicine (TCM) has not been fully exploited,resulting in the gap between the storage and usage of the TCM statistical data resources. The study on the retrospective collection, arrangement and application of Traditional Chinese Medicine Statistical Data aims to enhance the usage of TCM statistical data, basing on the collection and arrangement of the authoritative TCM statistical data, common analysis of the TCM statistical data from the founding of the People Republic of China.A pilot TCM Statistics Information Database and a TCM Health Statistics Data Query System have been established with the computer database technology, the object-oriented programming tool (C#) and the Internet Browser-based presentation programming tool (ASP. Net), providing the initial functions of the data retrieval and the graphical presentation of the search results on TCM statistics data. This paper explores "statistical data-oriented with attributes description" as the idea to establish the statistical database of complex statistical data, with the solution of the data problems such as numerous of data, diverse of data units, lack of regularity and hard to be classified. The study realizes the building of TCM Statistics Information Database and the retrieval finction of TCM statistical data, which lays a foundation on the building of Traditional Chinese Medicine Industry Statistics Database and the information services of TCM statistics data in the future.

Objective To explore the relationship between antifungal resistance and expression of a virulence factor phospholipase B1 in Candida albicans. Methods Total RNA was extracted from 15 fluconazole-resistant and 15 fluconazole-sensitive Candida albicans isolates. RT-PCR was performed to detect the expression of phospholipase B1 mRNA. Extracellular and intracellular proteins secreted by Candida albicans cells were concentrated using salting-out method and extracted by P0013B RIPA lysis buffer, respectively followed by Western-blotting analysis to detect the expression of extracellular and intracellular phospholipase B1 protein. Results The relative expression of phospholipase B1 mRNA was 0.6173 ± 0.1090 in fluconazoleresistant Candida albicans isolates, significantly higher than in fluconazole-sensitive isolates (0.2653 ± 0.0935,P ＜ 0.05). Increased expressions of extracellular and intracellular phospholipase B1 protein were noted in fluconazole-resistant Candida albicans isolates compared with fluconazole-sensitive isolates (0.4145 ± 0.2773 vs 0.2720 ± 0.2194, 0.1825 ± 0.1831 vs 0.2653 ± 0.0935, t = 2.703, 3.443, both P ＜ 0.05). Conclusions The expressions of phospholipase B1 mRNA and protein are elevated in fluconazole-resistant Candida albicans isolates, suggesting that the expression of phospholipase B1 may be associated with the occurrence of antifungal resistance in Candida albicans.

Objective To investigate the effect of hypertensive perfusion which induced by norepinephrine on the TNF-α and IL-6 in serum and the activity of Na~+-K~+-ATPase in lung tissue and to observe the morphology of lung tissue. Method Ten domestic pigs were suffered from ventricular fibrillation for 4 minutes and applied cardiopulmonary resuscitation. The pigs they were divided into two groups. Hypertensive perfusion group( n = 5) :the mean arterial pressure, which induced by norepinephrine was maintained as 130% as baseline for 4 hours; nor-real perfusion group( n = 5) : the mean arterial pressure was maintained as baseline for 4 hours, too. Hemodynamic parameters was observed, blood samples were extracted to detect the TNF-α and IL-6 in serum at the time of baseline, 10 min, 2 h and 4 h after successful resuscitation. The expression of Na~+ -K~+ -ATPase in lung tissue and the change of ultrastmeture and pathology in lung tissue was detected at 24 h. All values were analyzed by student' s t test. Results There was no influence on hemodynamic parameters except the blood pressure and heart rate in hypertensive perfusion group. The release of TNF-α and IL-6 were reduced(P < 0.01 ) and the activity of Na~+-K~+ -ATPase was upgraded in hypertensive perfusion group. Hypertensive perfusion could play a protective role on the morphology of alveolar cell. Conclusions Hypertensive perfusion which induced by norepinephrine could reduce the release of inflammatory cytokines, upgrade the activity of the Na~+-K~+-ATPase, decrease the consumption of surfactant and have an important protective effect on lung tissue.

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.

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.
