Objective To observe the effect of celastrol on the secretion of interleukin (IL)-17 in peripheral blood mononuclear cells in patients with sympathetic ophthalmia (SO), and its possible mechanisms. Methods Venous blood samples were extracted from 10 cases of sympathetic ophthalmia patients and 10 health objectives. The peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation and then were divided into 4 groups. Group A (control group): PBMCs of health objectives; Group B: PBMCs of SO patients; Group C: PBMCs of SO patients with 0.5 μmol/L celastrol in the medium; Group D:PBMCs of SO patients with 1 μmol/L celastrol in the medium. After culturing the cells for 3 days, the supernatant of 4 groups was collected, and the levels of IL-23 and IL-17 were detected by enzyme-linked immuno sorbent assay (ELISA). Then, the 50 ng/ml rIL-23 was added into the medium of group A which was the group A1; the 50ng/ml rIL-23 and 1 μmol/L Cela were added into to the medium of group A which was the group A2. For the medium of group B, the 50 ng/ml rIL-23 was added into the medium which was the group B1;the 50 ng/ml rIL-23 and 1 μmol/L celastrol were added into to the medium of group B which was the group B2. After culturing for 3 days, the supernatant of cells of these 4 groups was collected, and the levels of IL-17 were detected by ELISA.Results In group A, the levels of IL-23 and IL-17 were (228.43±17.27) pg/ml and (220.55±31.15) pg/ml respectively. In group B, the levels of IL-23 and IL-17 were (513.85±36.46) pg/ml and (866.77±72.92) pg/ml respectively. In group C, the levels of IL-23 and IL-17 were (381.07±20.93) pg/ml and (517.43±54.87) pg/ml respectively. In group D, the levels of IL-23 and IL-17 were (237.14±17.97) pg/ml and (242.89±34.09) pg/ml respectively. Between group A and D, there was no statistically significant difference in IL-23 or IL-17 level (P>0.05); but when comparing other groups, the differences were statistically significant (P<0.05). The levels of IL-17 in group A1 and group A2 were (428.43±24.53) pg/ml and (229.15±23.28) pg/ml and the difference was statistically significant (P<0.05). The levels of IL-17 in group B1 and group B2 were (1373.39±89.51) pg/ml and (571.01±94.88) pg/ml and the difference was statistically significant (P<0.05).Conclusion Celastrol can inhibit the secretion of IL-17 by PBMCs in SO patients via inhibiting the secretion of IL-23.

Objective:To observe the histopathological changes in peripheral retinal lesions under intraoperative optical coherence tomography (iOCT).Methods:A retrospective case series study. Eighty-eight patients (194 eyes) who underwent vitreoretinal surgery in the Department of Ophthalmology at the East Ward of the First Affiliated Hospital of Zhengzhou University from October 2021 to May 2022 in 94 eyes were included in the study. Among them, 49 cases were male and 39 cases were female, with the mean age of (50.93±17.55) years. Ninety-four eyes included 32 eyes with retinal detachment, 6 eyes with proliferative diabetic retinopathy, 28 eyes with vitreous hemorrhage, 8 eyes with ocular trauma, 14 eyes with the macular lesion, 1 eye with uveitis, 1 eye with family exudative vitreoretinopathy (FEVR), 1 eye with acute retinal necrosis (ARN), and 3 eyes with lens dislocation. All affected eyes were examined with iOCT during vitreoretinal surgery. The iOCT scanning of the peripheral retina was performed with the help of episcleral pressure. The pre-equatorial and serrated edge anterior and posterior of retinas were scanned according to the characteristics of different fundus diseases. Various abnormal fundus manifestations were recorded.Results:In 94 eyes, 53 eyes (56.38%, 53/94) have different types of retinopathy in the peripheral retina. Of these, 7 eyes (7.45%) have retinal cystoid degeneration; 19 eyes (20.21%) have lattice degeneration; and 8 eyes (8.51%) have pigment degeneration; 9 eyes (9.57%) have pavement-like degeneration; 7 eyes (7.45%) have small occult holes; 1 eye (1.06%) has familial exudative vitreoretinopathy (FEVR) serrated edge "dyke-like" proliferative degeneration; 4 eyes (4.26%) have vitreous and retinopathy adhesions; and one eye (1.06%) has ARN.Conclusion:With clear refractive media, iOCT can provide clear scans of different peripheral retinal lesions.

Objective:To understand the epidemic situation of HIV/AIDS and its change trend in the Belt and Road countries and provide evidence for the improvement of prevention and control of the cross-border transmission of HIV/AIDS.Methods:The 145 countries that have signed the cooperation document of the Belt and Road initiative with China were selected in our study. Age-standardized incidence rate and prevalence rate of HIV/AIDS in the 145 countries from 2013 to 2019 were downloaded from the Global Burden of Disease Study 2019. Age-standardized incidence rate and prevalence rate of HIV/AIDS in 2019 were used to describe the HIV/AIDS epidemics in 145 countries, and the estimated annual percentage change (EAPC) of incidence was calculated to analyze the trend of HIV/AIDS incidence from 2013 to 2019.Results:In 2019, Africa had the highest proportion of countries with HIV/AIDS incidence exceeding 40.00 per 100 000 (56.86%, 29/51), and Asia had the lowest proportion (5.41%, 2/37). The countries with the prevalence rate of HIV/AIDS exceeding 100.00 per 10 000 were almost distributed in Africa, accounting for 20.69% (30/145). From 2013 to 2019, the incidence rate of HIV/AIDS increased in 50 countries, accounting for 34.48% (50/145). The incidence rate of HIV/AIDS showed downward trends in 69 countries (47.59%, 69/145), and showed no significant change in 26 countries (17.93%, 26/145). The most obvious increase of incidence rate of HIV/AIDS was observed in Comoros (EAPC=15.60, 95% CI: 5.84-26.26) and the most obvious decrease was observed in Burundi (EAPC=-14.27, 95% CI: -15.21 to -13.31). Conclusions:In the Belt and Road countries, the most severe disease burden of HIV/AIDS was observed in countries in Africa, and the incidences of HIV/AIDS increased rapidly in some European countries, which means the risk of cross-border transmission still exists. Hence, the prevention and control of HIV/AIDS in China should be further strengthened in the future.
