Catechol-type siderophores secreted by a strain of soil bacteria in three different medium were assayed by two high-resolution TLC.The results showed different medium had a significant effect on the secretion of catechol-type siderophores,and in three different medium strain S1 produced different catechol-type siderophores.The effect of Al~(3+) on Catechol-type siderophores by S1 were also assayed.The results showed Al~(3+)had a significant stimulation on the secretion of catechol-type siderophores.Moreover,Al~(3+)could to some extent counteract the repression of Fe~(2+)on siderophores production.In KMB medium four catechol-type siderophores were identified and all ones except for 2,3-dihydroxybenzoic acid(2,3-DHBA) had high affinity for Al~(3+).

Background Retinal Müller cells can offer nutrient and maintain the normal structure of retina.Researches showed that the abnormality of Müiller cells leads to retinal vascular disease.To explore the effect of high glaucoma on retinal Müller cells is of a very important significance for the study on diabetic retinopathy (DR).Objective This study was to investigate the effects of different concentrations of glucose on retinal Müller cells in vitro.Methods Retinal tissue was isolated from 1 10-day-oM clean SD rat.Mtiller cells were cultured by explant culture method and passaged in DMEM containing 20％ fetal bovine serum.The third generation of cells were obtained and identified using glial fibrillary acidic protein (GFAP) staning.Then,5.5,30.0 and 40.0 mmol/L glucose were added into the culture medium for 4 days respectively.The proliferation (A570) of Müller cells was detected by MTT,and apoptosis rate of Müller cells was calculated by flow cytometer to evaluate the effects of 5.5,30.0 and 40.0 mmol/L glucose to cell vitality.Results Cultured and passaged cells grew well with the spindle shape.The positive reactive cells were ＞95％ for GFAP.The A570 value of Müller cells was 0.24±0.01,0.21±0.03 and 0.20±0.02 in 5.5,30.0 and 40.0 mmol/L glucose group respectively,showing a significant difference among the three groups(F=6.755,P＜0.05).Compared with 5.5 mmol/L glucose group,As70 values were significantly lower in 30.0and 40.0 mmol/L glucose group (q =0.645,0.486,P ＜ 0.05).Apoptosis rates of Miiller cells were (26.40 ±0.25)％,(30.19±0.16)％ and (36.23±0.19)％ in 5.5,30.0 and 40.0mmol/L glucose groups,with a significant difference among them (F =294.530,P＜0.05),and those in 30.0 and 40.0 mmol/L glucose groups were significantly reduced in comparison with 40.0 mmol/L glucose group (q =0.754,0.484,P ＜ 0.05).Conclusions High concentration of glucose inhibits the viability and promote the apoptosis of retinal Müller cells at a concentrationdependent manner.

AIM To evaluate the anti-angiogenesis action of Bevacizumab on corneal neovascularization(CNV) in rats induced by alkali burns.·METHODS: 20 Health Wistar rats, aging from 6 to 8 weeks and weighting from 170g to 190g from 170g to 190g were prepared for CNV animal models. Both corneas of each animal in experimental were cauterized with alkali, then all rats were randomly divided into four groups (each group have 5 rats and 10 corneas), the both corneas of each rats were received subconjunctival Bevacizumab in different dosage (group 2, 0.5rag; group 3, 1.0mg; group 4, 2.0mg)and the group 1 received carrier solution. The occurrence and development ofCNVwereobservedbyslit-lamp microscope, and length and area of CNV were calculated. All rats were followeded up 16 days after alkali burns. The 40 corneas were taken for histopathological examination. Vascular endothelial growth factor (VEGF) were detected in all rat corneas by immunohistochemistry method. ·RESULTS: In the bevacizumabotreated eyes, the vascular area was lower than in the control eyes. The treated group was statistical differences compared with the control group; when vascular area were compared between the treated groups, no statistical differences were observed. The histopathological findings showed that the inflammation cells and the neovascularity in each treated group were significantly fewer than that in the control group. The expression of VEGF markedly increased in CNV control group compared with bevacizumab-injected group. ·CONCLUSION: Subconjunctival application of a certain concentrations Bevacizumab could inhibit angiogenesis in rats corneas induced by alkali burns.

Objective To investigate the characteristics of the author groups in 《Chinese Journal of Geriatrics》,in order to provide references for the future construction and development of the author ranks.Methods Bibliometric method was used to analyze the quantity of papers,region distributions,core authors and cooperative rate in 《Chinese Journal of Geriatrics》 from 2009 to 2013.Results The total amount of papers published in 《Chinese Journal of Geriatrics》》 from 2009 to 2013 was 1636,involving 31 provinces,autonomous regions,municipalities and administrative region.Among these,Beijing,Zhejiang,Tianjin and Jiangsu were the 3 top contributing regions,accounting for 54.0 percent (884/1636 papers).The 1636 papers were contributed by 1435 authors (first authors),of whom 1275 authors published only one paper,accounting for 87.7％ (1275/1435),and their papers accounted for 77.9％ of the total published papers (1275 /1636).27 authors had high yield of 3 or more papers published and deep influence,and they published 95 papers (5.8％).The degree of cooperation was 4.6 (7599 /1636),and the cooperation rate was 93.8％ (1534/1636) within the five years.Conclusions 《Chinese Journal of Geriatrics》is quite influential and attractive in the fields of geriatrics,and a good cooperative relationship is displayed between different authors and authors' institutions.

Objective To explore the effect of different diary method on daily affect of college students.Methods 75 numbers of under-graduates were randomly assigned into information recording group,feeling recording group and control group.Beck Depression Inventory (BDI) and Positive And Negative Affect Scale (PANAS) were used before and after two months intervention.Results For positive emotion,ANOVA results showed no significant (P＞0.05) main effect of time,a significant (P＜0.05) main effect of group(2.76±0.41,2.97±0.50,3.24±0.45),and the time × group had a significant interaction (P＜0.05).Simple effect analysis showed that after the intervention,the positive emotions of information recording group (2.47 ± 0.62) and feeling recording group (2.86±0.64) was lower than the positive emotions of control group(3.35±0.46) significantly(P＜0.05).For negative emotions,there was no significant difference (P＞0.05) in main effects of time,group and interaction;for depression,the main effect of the level of time (8.02± 5.65,5.38 ± 5.04,5.20± 5.51) was significant (P＜ 0.01),and main effect of group and the interaction were not significant(P＞0.05).Conclusion Different diary methods have different effects on the subject's daily affect.
