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.

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.

Objective To investigate the protective effects of midazolam on noise-induced hearing loss in guinea pigs by testing reactive oxygen species (ROS) level in the cochlea and plasma SOD and MDA. Methods Totally forty male pigmented guinea pigs were randomly divided into four groups: control (C) , midazolam (M), normal saline (S) and noise-induced deafened (D) groups, with ten guinea pigs in each. Groups M, S and D were exposed to a continuous noise (4kHz , octave band, 100dB SPL) 3h every day for 3 consecutive days. Group M was treated with midazolam, which was administered intramuscularly (0.1mg/kg) 24h before noise exposure, and immediately upon and during noise exposure. Group S was exposed to noise and treated with the same volume of normal saline intramuscularly, the time of injection was the same as that of Group M. Group C was not exposed to noise, but was treated with midazolam intramuscularly, the time of injection and the dosage were the same as those of Group M. Group S was exposed to noise and treated with normal saline intramuscularly ,the time of injection was same with that of Group M.Group D was exposed to noise only. All animals received auditory brainstem response (ABR) threshold recording before and immediately after noise exposure. Blood was collected when the guinea pigs were killed after the last ABR threshold recording, and serum SOD activity and MDA content were detected. Both the cochleae were removed and prepared for ROS assay. Results After noise exposure, ABR threshold shift (1.6±1.5) and ROS content [(291.10±2.30)u/mL] in Group M were significantly lower than those in Groups S and D [41.7±3.3, 44.3±3.9; (348.52±3.60)u/mL, (315.56±6.70)u/mL, P<0.05]. Serum SOD activity and MDA content were significantly increased in Group M, but the amplitude was less than that in Groups S and D.Conclusion Midazolam can prevent noise-induced hearing loss by reducing the increased ROS level in the cochlea after noise exposure.

Objective To observe the change of six cytokines in mice infected with Echinococcus multilocularis as part of the study on immunological mechanism in the infection. Methods Mice were infected by abdominal inoculation of echinococcus protoscoleces. The change of serum level of the cytokines IL-2、IFN-?、TNF-?、IL-4、 IL-5 and IL-10 was determined by ELISA during the infection which lasted for 260 d. Results Compared with uninfected control, the levels of the cytokines all significantly increased in the 260 d. The level of IL-2 reached a peak after 80 d post-infection (p.i.), then decreased quickly after 140 d p.i., High level of TNF-? was detected after 40 d, compared to uninfected control, reached a peak at 100 d p.i., and decreased quickly after 140 d. The level of IFN-? reached a peak after 80 d p.i., and decreased slowly after 140 d p.i., The levels of IL-4, IL-5 and IL-10 remained lower before 80 d, and increased sharply after 100 days. The levels of IL-4 and IL-10 reached peaks at 100 d p.i., and that of IL-5 at 140 d p.i. Conclusion The data suggest that the induction of Th2 antibody-mediated immunity (AMI) with a parallel expansion of Th1 cell-mediated inflammatory (CMI) responses are important mechanism of the host in defending against the metacestodes. Th1 CMI plays an important role at the early stage of infection, and Th2 AMI is important in the later stage of infection.
