Objective To investigate the clinical efficacy and safety of brinzolamide combined with travoprost in the treatment of primary open-angle glaucoma.Methods 112 cases(140 eyes)of open-angle glaucoma patients from March 2015 to March 2016 were selected and randomly divided into the group A and the group B 56 cases(70 eyes)in each group.The group A was treated with travoprost therapy,while the group B was given travoprost combined with brinzolamide treatment,the adverse reactions and clinical curative effects in the two groups were observed and compared during treatment.Results After two weeks,one months,three months and six months in the two groups intraocular pressure were significantly lower than those before treatment,the difference was statistically significant(P<0.05),but in two weeks,one months,three months and six months in the group B the intraocular pressure was significantly lower than that in the group A,the difference was statistically significant(P<0.05).After treatment,two groups of BUT and ST were decreased significantly lower than before treatment,the difference was statistically significant(P<0.05),but there was no significant difference between BUT and ST after treatment,two groups of corneal fluorescein staining and ocular; Bengal staining scores were all significantly higher than before treatment,the difference was statistically significant(P<0.05),however,there was no significant difference in corneal fluorescein staining and ocular surface of rose bengal staining between the two groups.There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion Brinzolamide combined with travoprost can reduce the intraocular pressure of patients with primary open-angle glaucoma,but can reduce tear film stability,damage the cornea,conjunctiva,reduce tear secretion,there is some damage to the conjunctiva,cornea,similar with travoprost.

A serious leaf disease caused by Colletotrichum dematium was found during the cultivationof Sarcandra glabra in Jingxi, Rong’an, and Donglan Counties in Guangxi Province, whichinflicted huge losses to plant productivity. Biological control gradually became an effectivecontrol method for plant pathogens. Many studies showed that the application of actinomycetesin biological control has been effective. Therefore, it may be of great significance tostudy the application of actinomycetes on controlling the diseases caused by S. glabra.Strains of antifungal actinomycetes capable of inhibiting C. dematium were identified, isolatedand screened from healthy plants tissues and the rhizospheres in soils containing S.glabra. In this study, 15 actinomycetes strains were isolated and among these, strains JT-2F,DT-3F, and JJ-3F, appeared to show antagonistic effects against anthracnose of S. glabra.The strains JT-2F and DT-3F were isolated from soil, while JJ-3F was isolated from plantstems. The antagonism rate of strain JT-2F was 86.75%, which was the highest value amongthe three strains. Additionally, the JT-2F strain also had the strongest antagonistic activitywhen the antagonistic activities were tested against seven plant pathogens. Strain JT-2F isable to produce proteases and cellulase to degrade the protein and cellulose componentsof cell walls of C. dematium, respectively. This results in mycelia damage which leads toinhibition of the growth of C. dematium. Strain JT-2F was identified as Streptomyces tsukiyonensisbased on morphological traits and 16S rDNA sequence analysis.

In view of the challenges and opportunities presented in the new century and after rational deliberations on five occasions, the completely new model of "hi tech+humanistic solicitude=the green hospital" was put forward and the overall framework of "one line of thought", "two cornerstones", and "three goals" was carefully formulated. In the meantime, all staff members of the hospital were called on to be involved in the "six major activities". As a result, great changes have taken place in the appearance and development of the hospital. It has been proved through practice that "the green hospital" is a successful model conforming to the trends of the times.

Objective:To investigate the effects of micropulse laser photocoagulation under threshold on serum malondialdehyde(MDA) and chemokine levels in patients with proliferative diabetic retinopathy(PDR).Methods:From October 2014 to February 2016, 102 patients with PDR who were treated in Lishui People's Hospital were selected and divided into two groups by random number table method, with 51 cases in each group.The patients in the control group were treated with traditional grating laser, and the patients in the observation group were treated with micropulse laser photocoagulation under threshold.The levels of MDA and chemokine were compared before and after treatment, and the changes of vision and clinical efficacy were observed.Results:The total effective rate of the observation group was 90.20%(46/51), which was higher than that of the control group [76.47%(39/51)](χ 2=19.585, P<0.01). Before treatment, there were no statistically significant differences in serum MDA, chemokine and visual acuity between the two groups(all P>0.05). After treatment, the serum MDA and chemokines in the observation group were (8.57±2.48)μmol/L and (1.58±0.51)ng/L, respectively, which were lower than those in the control group [(10.92±3.16)μmol/L and (2.83±0.92)ng/L]( t=4.178, 8.486, all P<0.05), which in both two groups after treatment were lower than those before treatment(all P<0.05). The visual acuity of the observation group was (0.66±0.19), which was higher than that of the control group(0.43±0.13)( t=7.135, P<0.05). Conclusion:Micropulse laser photocoagulation under threshold can effectively alleviate oxidative stress and reduce serum MDA and chemokine levels in patients with PDR.

Objective:To investigate the therapeutic effects of conbercept combined with retinal laser photocoagulation on diabetic macular edema (DME) and the effects of the combined therapy on best corrected visual acuity, macular fovea thickness, vascular endothelial growth factor (VEGF) and human stromal cell-derived factor 1 (SDF-1) levels in aqueous humor of patients with DME.Methods:Ninety patients with DME who received treatment in Lishui People's Hospital between November 2016 and December 2019 were included in this study. They were randomly assigned to undergo retinal laser photocoagulation (control group, n = 45) or retinal laser photocoagulation combined with conbercept treatment (study group, n = 45). Therapeutic effects, best corrected visual acuity, macular fovea thickness, and VEGF and SDF-1 levels in aqueous humor were compared between the two groups. The incidence of complications was compared between the two groups. Results:Total response rate in the study group was significantly higher than that in the control group [88.89% (40/45) vs. 68.89% (31/45), χ2 = 5.40, P = 0.020]. After 3 months of treatment, VEGF and SDF-1 levels in aqueous humor were (138.71 ± 16.82) ng/L and (415.18 ± 24.87) mg/L, respectively, which were significantly lower than those in the control group [(276.13 ± 15.96) ng/L, (526.06 ± 22.91) mg/L, t = 39.76, 21.98, both P < 0.001]. After 3 months of treatment, macular fovea thickness and best corrected visual acuity in the study group were (339.52 ± 30.12) μm and 0.47 ± 0.08, respectively, which were significantly lower than those in the control group [(398.65 ± 28.23) μm, 0.36 ± 0.09, t = 6.13, 9.61, both P < 0.01]. There was no significant difference in the incidence of complications between the two groups [13.33% (6/45) vs. 11.11% (5/45), χ2 = 0.10, P > 0.05]. Conclusion:Conbercept combined with retinal laser photocoagulation for the treatment of DME has a definite therapeutic effect. The combined therapy can greatly improve the best corrected visual acuity, reduce macular fovea thickness, decrease VEGF and SDF-1 levels in aqueous humor, and does not increase the incidence of complications. Findings from this study have a certain clinical application value.
