Objective To investigate the anxiety， depression and sleep disorders in patients with early dysfunctional filtration blebs who underwent needle revision of filtration bleb after glaucoma trabeculectomy. Methods We selected 30 patients who recovered to normal 6 months after glaucoma trabeculectomy(Group A), 30 patients with early dysfunc‐ tional filtration blebs who underwent needle revision of filtration bleb after glaucoma trabeculectomy(Group B), and 30 healthy adults(Group C) . Anxiety， depression and sleep disorders were scored using Self-Rating Anxiety Scale(SAS), Self-Rating Depression Scale(SDS) and Pittsburgh Sleep Quality Index(PSQI) . We compared SAS， SDS， PSQI scores and the positive rate of anxiety， depression and sleep disorders among the three groups. The correlation of SAS， SADS and PSQI scores in patients with early dysfunctional filtration blebs was analyzed by Spearman correlation analysis. Results There were no significant differences in gender， age， educational level or marital status among the three groups(all P> 0. 05), and the balance between the groups was comparable. Significant differences were found in SAS， SDS and PSQI scores between the three groups(all P<0. 05) . There were significant differences in SAS， SDS and PSQI scores between the groups B and C(all P<0. 05) . Significant difference was found in PSQI score between group A and group C(P< 0. 05) . SAS score of 45， SDS score of 50， and PSQI score of> 7 were used as the positive determination criteria for anxi‐ ety， depression， and sleep disorders， respectively. There were significant differences in the positive rates of depression and sleep disorders among these three groups(all P<0. 05) . Significant differences were found in the positive rates for anx‐ iety， depression and sleep disorders between the group B and group C(all P<0. 05) . There was significant difference in the positive rate of sleep disorder between groups B and A， and between groups A and C(all P<0. 05) . PSQI score was positively correlated with SAS score(r=0. 511) and SDS score(r=0. 296) in patients of group B(P<0. 05), and SAS score was positively correlated with SDS score(r=0. 355，P<0. 05) . Conclusion Patients with early dysfunctional filtration blebs who underwent needle revision of filtration bleb after glaucoma trabeculectomy have high incidences of anxiety， depression and sleep disturbance within 6 months， so necessary psychological intervention should be given.

Objective To investigate the effect of Conbercept on fiber scar formation in rabbit filter channel after trabeculectomy. Methods Forty healthy New Zealand white rabbits were randomly divided into four groups: trabeculectomy combined with mitomycin group (group A), trabeculectomy combined with Conbercept injection group (group B), trabeculectomy combined with mitomycin and Conbercept injection group (group C), trabeculectomy combined with normal saline injection group (group D), with 10 rabbits in each group. Standard trabeculectomy was performed on the right eyes of rabbits. The intraocular pressure (IOP) was measured before and after the operation, and the morphology and complications were observed by slit-lamp microscope. At 28 days after surgery, the operative eye was removed and the tissues of the follicle area were clipped. HE staining was used to observe the histopathologic changes of the filter passage, Masson staining was used to observe the collagen deposition and fibrosis degree of the filter passage tissues, and immunohistochemical staining was used to observe the expression of CD31 in the filter passage tissues. Results The IOP in each group decreased to the lowest on the 3rd day after surgery, gradually increased on the 7th day after surgery, and almost completely recovered to the preoperative level on the 28th day after surgery. At 7 days after surgery, functional follicles were formed in the operative area of groups A, B and C, while conjunctival vessels on the follicle surface of group D were dense, with obvious vascularization and flat follicle area. Among them, the height of follicles in the group A increased and the surface blood vessels were sparse. In the group B, the diffusion of follicles increased, and there was no obvious congestion on the follicle surface. In the group C, the diffusion of follicles increased, and there was no obvious congestion on the surface of follicles and conjunctiva. As time went on, to 28 days after surgery, the conjunctival congestion gradually decreased and faded away, and the filtration vesicles were limited and flattened. At 28 days after operation, the histopathological features of the eyes in the groups A and B were similar, showing loose collagen fiber arrangement and local thickened epithelial tissues, accompanied by dot infiltration of lymphocytes. More epithelial cell degeneration, cell swelling and cytoplasmic vacuolation were observed in the groups A and C, while no such pathological changes were observed in the group B. At 28 days after surgery, the proportion of collagen fibers in the filter aisle in the groups A, B and C was lower than that in the group D (all P<0. 05), and the proportion of collagen fibers in the filter aisle in the group B was lower than that in the groups A and C (both P<0. 05) . The number of microvessels in the group B was significantly smaller than that in the groups A, C and D (all P<0. 05) . Conclusion Conbercept can inhibit the formation of neovascularization and scarring in the rabbit filter passage after trabeculectomy, and help maintain the shape of the filter vesicle, so as to effectively improve the success rate of glaucoma trabeculectomy.

Tetrahydropyrrole was prepared by using SO42-/γ-Al2O3 as catalyst and tetrahydrofuran as raw material. Through the investigation of the catalytic properties of various solid acid catalysts, it has been found that higher tetrahydropyrrole selectivity can he obtained by using SO42-/γ-Al2O3 catalyst. Through the optimization of catalyst preparation conditions and reaction conditions, the results of the preparation conditions show that sulfuric acid concentration of 0.2 mol/L, calcined at 500 °C for 4 h. When the reaction temperature is 350 °C , liquid hourly space velocity is 0.2 h-1, n (NH3): n (TIIF) is 6:1, the reaction conversion is 91.2% and the selectivity is 80.5%. Through the life test of the catalyst, a stable tetrahydropyrrole yield can he obtained within 150 h. [ABSTRACT FROM AUTHOR]
