Public Health Ophthalmology is a population-,region-or country-based as a whole object,and is committed to improving the eye health of the whole population.Epidemiological investigation of the eye was named to the region from a single disease to variation of diseases from cross-sectional survey to a longitudinal cohort study.Epidemiological investigations is the most important way which can reflect the pathogenic factors for public health policy-making,early diagnosis and prevention and treatment of eye disease,and Research to Prevent Blindness.Imaging Diagnosis,quality control,improve the reliability of the epidemiological investigation,and to strengthen the study of disease,race,and molecular levels and create a unique epidemiological study.

Objective To study the effects of bone marrow mononuclear cells (MNCs) transplantation on left ventricular (LV) remodeling and its potential mechanism in swine myocardial infarction models. Methods The left anterior descending coronary arteries of swines were obstructed by balloon to create myocardial infarction models. Three weeks later, MNCs(n= 7)or PBS(n=5) were injected into the infarction related coronary arteries through balloon catheter. The cardiac function were measured by echocardiography and ventriculargraphy. Collagen amount was also assessed at 4 weeks after transplantation. Results At 4 weeks after transplantation, LV end-diastolic dimension decreased in the BM-MNC group than before (40.40?4.51 mm vs. 45.88?4.15 mm, P=0.026), but increased in the control group (48.50?9.31 mm vs. 42.40?7.29 mm, P=0.328). Left ventricular function was improved from 41.16%?9.83% to 47.50%?9.07% in the BM-MNC group (P=0.020) but there was no significant change in the control group. Significant differences existed between the 2 groups in their absolute change before and after the procedure in both LV dimension and LV function (P=0.046 and P=0.030 respectively). The results showed reduction of collagen content in the border and the remote infarct regions in the BM-MNC group compared with the control (P=0.047 and P=0.034 respectively). Conclusion BM-MNCs transplantation regulates collagen content in heart and attenuates the degree of post-MI LV dilation and the development of infarction area. This effect of BM-MNCs transplantation may be one of the mechanisms which intervene ventricular remodeling following myocardial infarction.

Objective To investigate the effect of early warning face pattern of weight combined with health education in weight management of maintenance hemodialysis patients.Methods Toally 223 maintenance hemodialysis patients hospitalized in the hospital from July to December 2014 (17,617 cases of hemodialysis) were set as the control group and 223 maintenance hemodialysis patients from January to June 2015 (17,281 cases of hemodialysis) were set as the experiment group.The control group was given routine health education and the experiment group was given health education and early warning face pattern of weight.The two groups were compared in terms of the ratio between interdialytic weight gain (IDWG) and interdialytic dry weight ratio (IWGR) as well as the hemodialysis-related complications.Results The IDWG/IWGR ratio in the experiment group was significantly better than that of the control group (P＜0.05).The incidence of hemodialysis-related complications were significantly lower than that of control group.Conclusion Early warning face pattern of weight used in health education can effectively control the patient's interdialytic weight gain (IDWG) and reduce the hemodialysis-related complications.

OBJECTIVE:To investigate the effect of bayberry polyphenol(BPP) on thrombopenia induced by cytotoxic drug and radiation in mice and rats.METHODS:The mice and rats were treated with cyclophosphamide and 60Co-? radiation to establish the animal thrombopenia models.RESULTS:Platelet counts were increased in BPP treated animals with a significant difference compared with the controls(P

Objective To further define the molecular mechanism involved in the metastasis process in lung cancer and screen out the genes expressed differentially in the lung cancer.Methods mRNA differential display (DD-PCR) was employed to search the specific genes related to metastasis.The highly expressed fragments were cloned and sequenced.Compared with the data in GenBank,the homologous genes were found.The anchor primers were designed to validate the candidates from DD-PCR by real-time PCR.The structure of the gene was prognosticated by software.Results Nine differentially expressed genes were found.One of the nine genes,which named C3orf1,showed high different expression within the six tested cancer cells.The gene was 858bp long and encoded 285 amino acids.The molecular weight was about 32.2 kD.Analyzed by the bio-software,it was found that the gene was consisted with seven EGF-like domains (EGF_1),three 2Fe-2S ferredoxin/iron-sulfur binding regions (2FE2S_FER_1),two VWFC domains (VWFC_1),two thiolase active sites (thiolase_3),and so on.Conclusions The gene C3orf1 is over-expressed in the lung cancer 95D cells.It may encode a familiar secretary growth factor protein and play important role in stimulating growth of the cells.

Garcinia plants are one of the rich sources of natural xanthones and benzophenones which have attracted a great deal of attention from the scientists in the fields of chemistry and pharmacology. Recently, many structurally unique constituents with various bioactivities, especially anti-tumor activity, have been isolated from Garcinia plants. This concise review focused on the anti-cancer activity natural products isolated from Chinese Garcinia plants, and the research finding by authors and collaborators over the past several years were cited.
