International Eye Science 2015;(8):1458-1460
AIM: To study the risk factors of endophthalmitis after cataract surgery and prognosis of endophthalmitis after vitrectomy.
METHODS: One thousand nine hundred patients ( 1 900 eyes) of receiving cataract surgery in our hospital were selected and divided into infection group and control group according to the incidence of endophthalmitis. The influence of clinical index in the endophthalmitis after cataract surgery as well as related risk factors based on single factor and multi- factor Logistic regression was analyzed. All patients with endophthalmitis were received vitrectomy, and the prognosis of endophthalmitis after vitrectomy was observed.
RESULTS: Based on single factor analysis, the risk factors of endophthalmitis after cataract surgery including age, hypertension, diabetes mellitus, vitreous loss, operation time, common operating room and nonuse of anesthetics in the required time lead to the ocurrence of endophthalmitis after cataract surgery (P<0. 05). Based on multi-factor Logistic regression, the independent risk factors of endophthalmitis after cataract surgery included age (≥70 years old ) , hypertension, diabetes mellitus, vitreous loss, operation time (≥ 10min ), common operating room and nonuse of anesthetics in the required time (P<0. 05). After vitrectomy, the vision of patients was significantly improved (P<0. 05).
CONCLUSION:The risk factors of endophthalmitis after cataract surgery include age, hypertension, diabetes mellitus, vitreous loss, operation time, common operating room and nonuse of anesthetics in the required time. Vitrectomy can significantly improve the vision of patients.

The coronavirus disease 2019 (COVID-19) is an acute infectious disease caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which has led to serious worldwide economic burden. Due to the continuous emergence of variants, vaccines and monoclonal antibodies are only partial effective against infections caused by distinct strains of SARS-CoV-2. Therefore, it is still of great importance to call for the development of broad-spectrum and effective small molecule drugs to combat both current and future outbreaks triggered by SARS-CoV-2. Cathepsin L (CatL) cleaves the spike glycoprotein (S) of SARS-CoV-2, playing an indispensable role in enhancing virus entry into host cells. Therefore CatL is one of the ideal targets for the development of pan-coronavirus inhibitor-based drugs. In this study, a CatL enzyme inhibitor screening model was established based on fluorescein labeled substrate. Two CatL inhibitors IMB 6290 and IMB 8014 with low cytotoxicity were obtained through high-throughput screening, the half inhibition concentrations (IC50) of which were 11.53 ± 0.68 and 1.56 ± 1.10 μmol·L-1, respectively. SDS-PAGE and cell-cell fusion experiments confirmed that the compounds inhibited the hydrolysis of S protein by CatL in a concentration-dependent manner. Surface plasmon resonance (SPR) detection showed that both compounds exhibited moderate binding affinity with CatL. Molecular docking revealed the binding mode between the compound and the CatL active pocket. The pseudovirus experiment further confirmed the inhibitory effects of IMB 8014 on the S protein mediated entry process.
