ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

BACKGROUND:In recent years,increasing studies have focused on the abnormal proliferation and differentiation of acinous cells in the meibomian gland,suggesting that this process is closely related to the occurrence and development of dry eye.Structural and functional abnormalities such as blockage of the lumen of the meibomian gland and atrophy of the glands can cause or exacerbate dry eye.Therefore,the study of changes in the meibomian glands in dry eyes is important for understanding the pathogenesis of dry eyes in depth and finding new targets for the treatment and prevention of dry eyes. OBJECTIVE:To investigate the changes of the meibomian gland in a mouse model of aqueous deficient dry eyes. METHODS:Thirty-two female C57/B6 mice at 6-8 weeks were selected and randomly divided into experimental and control groups with 16 mice in each group.The mice in the experimental group were constructed by removing both the extra-orbital and intra-orbital lacrimal glands,while those in the control group were not treated.After 2 weeks of normal feeding,the corneal changes of both groups were observed under a slit lamp,and the tear secretion of both groups was measured.The meibomian glands of the two groups of mice were removed after decapitation.The changes in the gross morphology of the meibomian glands were observed and the meibomian glands were made into frozen sections.Hematoxylin-eosin staining was used to observe the structure of the meibomian glands,oil red staining was used to evaluate the function of the meibomian glands,and immunofluorescence staining and RT-qPCR were used to observe the expression of cytokeratin 14,Ki67 and abnormally differentiated small proline-rich protein 1B in the meibomian glands of mice. RESULTS AND CONCLUSION:Two weeks after modeling,lamellar defects were seen in the corneas of the experimental mice,and neovascularization of the limbal corneal was generated and invaded the central cornea.(2)Tear secretion volume was significantly reduced in the experimental group compared with the control group(P<0.05).Microscopic findings showed that the ducts of the meibomian glands in the experimental group were interrupted and atrophied,and their arrangement was disorganized.Hematoxylin-eosin staining results showed a significant increase in lipid vacuoles in the meibomian glands of the experimental mice compared with the control group.Lipid deposition was seen in oil red staining in the experimental group.Immunofluorescence and RT-qPCR results showed a significant increase in the expression of cytokeratin 14,Ki67 and small proline-rich protein 1B in the meibomian glands of mice in the experimental group compared with the control group(P<0.05).To conclude,aqueous deficient dry eye can lead to compensatory hypertrophy,increased proliferation,and abnormal lipid metabolism in the meibomian gland,as well as abnormal differentiation of the meibomian gland.

Objective To compare and analyze the tilt and decentration of the intraocular lens in patients receiving four-point and two-point suspension fixation,as well as their relationship with visual prognosis.Methods A total of 80 patients(80 eyes)who underwent intraocular lens suspension fixation at the Ophthalmology Department of Baoding No.1 Central Hospital from June 2021 to April 2022 were selected as the subjects.These patients were randomly divided into the experimental group(41 patients,41 eyes,underwent four-point suspension fixation)and the control group(39 patients,39 eyes,underwent traditional two-point suspension fixation).They were followed up for at least 6 months after surgery to re-cord their uncorrected visual acuity(UCVA)and best corrected visual acuity(BCVA)before surgery and at the last follow-up.The tilt angle and decentration distance of the intraocular lens of patients in the two groups were measured after surger-y by a panoramic ultrasound biomicroscope.The preoperative and last follow-up UCVA and BCVA of patients in the two groups,as well as tilt angle and decentration distance of the intraocular lens after surgery,were compared,and the corre-lation between tilt angle,decentration distance and postoperative UCVA,BCVA was analyzed by Person correlation analy-sis.Results The UCVA and BCVA at the last follow-up in the experimental group and control group were better than those before surgery(all P＜0.05).The difference in postoperative UCVA between the experimental group and the control group was statistically significant(t=-6.20,P=0.00),and the experimental group had better postoperative UCVA than the control group.There was no statistically significant difference in postoperative BCVA between the experimental group and the control group(t=-1.43,P=0.16).The postoperative horizontal and vertical tilt angles of the intraocular lens in the experimental group were 0.70°±0.24° and 0.60°±0.16°,respectively;while those in the control group were 2.66°± 1.40° and 3.76°±0.67°,respectively.The differences between the two groups were statistically significant(t=-8.51 and-29.42,P=0.00 and 0.00).The postoperative horizontal and vertical decentration distances of the intraocular lens in the experimental group were(0.24±0.10)mm and(0.25±0.10)mm,respectively,while those in the control group were(0.85±0.77)mm and(2.14±0.50)mm,respectively.The differences between the two groups were statistically signifi-cant(t=-4.82 and-21.68,P=0.00 and 0.00).In the experimental group,neither the horizontal and vertical tilt angles of intraocular lenses nor the horizontal and vertical decentration distances were correlated with postoperative UCVA and BCVA(all P＞0.05).In the control group,the horizontal tilt angle of intraocular lenses was positively correlated with post-operative UCVA and BCVA(both P＜0.05),while the vertical tilt angle was not correlated with postoperative UCVA and BCVA(both P＞0.05);the horizontal decentration distance was positively correlated with postoperative UCVA and BCVA(both P＜0.05),but the vertical decentration distance was not correlated with postoperative UCVA and BCVA(both P＞0.05).Conclusion Both four-point suspension fixation and traditional two-point suspension fixation can effectively im-prove postoperative vision of patients,while the tilt and decentration of the intraocular lens are smaller after four-point sus-pension fixation.

Objective To investigate the effects of total flavones of Dracocephalum moldavica L.(TFDM)on oxida-tive damage to retinal ganglion cells(RGCs)induced by high glucose(HG)and its mechanism.Methods RGCs of mice were taken as the research subjects.RGCs were inoculated in 24-well plates(with 2.5 × 104 cells in each well)and divided into control group(cultured with medium containing 10％fetal bovine serum for 48 h),HG group(cultured with medium containing 30 mmol·L-1 glucose for 48 h),HG+TFDM-L group(cultured with medium containing 30 mmol·L-1 glucose and 25 mg·L-1 TFDM for 48 h),HG+TFDM-M group(cultured with medium containing 30 mmol·L-1 glucose and 50 mg·L-1 TFDM for 48 h),HG+TFDM-H group(cultured with medium containing 30 mmol·L-1 glucose and 100 mg·L-1 TFDM for 48 h),miR-NC group(transfected with miR-NC and then cultured with medium containing 30 mmol·L-1 glu-cose for 48 h),miR-93-5p group(transfected with miR-93-5p mimics and then cultured with medium containing 30 mmol·L-1 glucose for 48 h),anti-miR-NC group(transfected with anti-miR-NC and then cultured with medium containing 100 mg·L-1 TFDM and 30 mmol·L-1 glucose for 48 h),and anti-miR-93-5p group(transfected with anti-miR-93-5p and then cultured with medium containing 100 mg·L-1 TFDM and 30 mmol·L-1 glucose for 48 h).Levels of RGCs oxidative stress indexes in each group were detected according to the kit instructions.The thiobarbituric acid method was used to measure the level of malondialdehyde(MDA),the colorimetric method was adopted to detect the levels of catalase(CAT)and 8-hydroxydeoxyguanosine(8-OHdG),apoptosis rate was detected by flow cytometry,the messenger ribonucleic acid(mR-NA)expressions were analyzed by real-time quantitative polymerase chain reaction,the targeting regulation of miR-93-5p and E2F transcription factor 1(E2F1)were verified by dual luciferase reporter assay,and the protein expressions were de-tected by Western blot.Statistical analysis was conducted on the data of each group.Results In the HG group,the lev-els of MDA and 8-OHdG,apoptosis rate and Bax protein expression of RGCs were higher than those in the control group(all P＜0.05);the CAT level and Bcl-2 protein expression were lower than those in the control group(both P＜0.05).In the HG+TFDM-L group,HG+TFDM-M group and HG+TFDM-H group,the levels of MDA and 8-OHdG,apoptosis rate and Bax protein expression of RGCs were lower than those in the HG group(all P＜0.05);the CAT level and Bcl-2 protein expression were higher than those in the HG group,and those indexes gradually tended to those in the control group with the increase of TFDM concentrations(all P＜0.05).In the HG group,the miR-93-5p expression in RGCs was lower than that in the control group,and the mRNA and protein expressions of E2F1 were higher than those in the control group(all P＜0.05).In the HG+TFDM-L group,HG+TFDM-M group and HG+TFDM-H group,the miR-93-5p expression in RGCs was higher than that in the HG group,and the mRNA and protein expressions of E2F1 were lower than those in the HG group(all P＜0.05).The protein expression of E2F1 in RGCs of the miR-93-5p group was lower than that in the miR-NC group,and the protein expression of E2F1 in RGCs of the anti-miR-93-5p group was higher than that in the anti-miR-NC group(both P＜0.05).In the miR-93-5p group,the miR-93-5p expression was higher than that in the miR-NC group,the levels of MDA and 8-OHdG,apoptosis rate,and protein expressions of Bax and E2F1 were lower than those in the miR-NC group,and the CAT level and Bcl-2 protein expression were higher than those in the miR-NC group(all P＜0.05).Con-clusion TFDM can inhibit oxidative stress and cell apoptosis,and then reduce the damage to RGCs induced by HG.The mechanism may involve the regulation of miR-93-5p/E2Fl expression.

Objective To create risk predictive models of healthcare-seeking delay among imported malaria patients in Jiangsu Province based on machine learning algorithms, so as to provide insights into early identification of imported malaria cases in Jiangsu Province. Methods Case investigation, first symptoms and time of initial diagnosis of imported malaria patients in Jiangsu Province in 2019 were captured from Infectious Disease Report Information Management System and Parasitic Disease Prevention and Control Information Management System of Chinese Center for Disease Control and Prevention. The risk predictive models of healthcare-seeking delay among imported malaria patients were created with the back propagation (BP) neural network model, logistic regression model, random forest model and Bayesian model using thirteen factors as independent variables, including occupation, species of malaria parasite, main clinical manifestations, presence of complications, severity of disease, age, duration of residing abroad, frequency of malaria parasite infections abroad, incubation period, level of institution at initial diagnosis, country of origin, number of individuals travelling with patients and way to go abroad, and time of healthcare-seeking delay as a dependent variable. Logistic regression model was visualized using a nomogram, and the nomogram was evaluated using calibration curves. In addition, the efficiency of the four models for prediction of risk of healthcare-seeking delay among imported malaria patients was evaluated using the area under curve (AUC) of receiver operating characteristic curve (ROC). The importance of each characteristic was quantified and attributed by using SHAP to examine the positive and negative effects of the value of each characteristic on the predictive efficiency. Results A total of 244 imported malaria patients were enrolled, including 100 cases (40.98%) with the duration from onset of first symptoms to time of initial diagnosis that exceeded 24 hours. Logistic regression analysis identified a history of malaria parasite infection [odds ratio (OR) = 3.075, 95% confidential interval (CI): (1.597, 5.923)], long incubation period [OR = 1.010, 95% CI: (1.001, 1.018)] and seeking healthcare in provincial or municipal medical facilities [OR = 12.550, 95% CI: (1.158, 135.963)] as risk factors for delay in seeking healthcare among imported malaria cases. BP neural network modeling showed that duration of residing abroad, incubation period and age posed great impacts on delay in healthcare-seek among imported malaria patients. Random forest modeling showed that the top five factors with the greatest impact on healthcare-seeking delay included main clinical manifestations, the way to go abroad, incubation period, duration of residing abroad and age among imported malaria patients, and Bayesian modeling revealed that the top five factors affecting healthcare-seeking delay among imported malaria patients included level of institutions at initial diagnosis, age, country of origin, history of malaria parasite infection and individuals travelling with imported malaria patients. ROC curve analysis showed higher overall performance of the BP neural network model and the logistic regression model for prediction of the risk of healthcare-seeking delay among imported malaria patients (Z = 2.700 to 4.641, all P values < 0.01), with no statistically significant difference in the AUC among four models (Z = 1.209, P > 0.05). The sensitivity (71.00%) and Youden index (43.92%) of the logistic regression model was higher than those of the BP neural network (63.00% and 36.61%, respectively), and the specificity of the BP neural network model (73.61%) was higher than that of the logistic regression model (72.92%). Conclusions Imported malaria cases with long duration of residing abroad, a history of malaria parasite infection, long incubation period, advanced age and seeking healthcare in provincial or municipal medical institutions have a high likelihood of delay in healthcare-seeking in Jiangsu Province. The models created based on the logistic regression and BP neural network show a high efficiency for prediction of the risk of healthcare-seeking among imported malaria patients in Jiangsu Province, which may provide insights into health management of imported malaria patients.

Oxidative stress by different oxygen concentrations can cause damage to the immature intestinal tract of newborns and preterm infants.Newborns, especially premature infants, have underdeveloped intestinal tracts, immature immune function, increased susceptibility to oxidative stress, and are prone to intestinal inflammatory diseases.Both hypoxia and hyperoxia can trigger oxidative stress, leading to intestinal damage.Histological changes include damage to the intestinal barrier, watery degeneration of the intestinal epithelium, and reduced goblet cells and villi.Hypoxia-induced intestinal injury is affected by a variety of signaling pathways including CRF-TLR4, Grx1-HIF-VEGF, NLRP3-Caspase-1, and miRNA-SIRT axis.The intestinal injury induced by hyperoxia is closely related to TLR4/NF-κB signaling pathway, Nrf2/IL-17D axis, and ASK1-MAPK cascade.This review focuses on the histological changes and molecular pathways of hypoxic or hyperoxic-induced intestinal injury to establish a framework for potential interventions.

Objective:To investigate the clinical efficacy of osimertinib combined with tislelizumab in the treatment of advanced non-small cell lung cancer (NSCLC) and the survival status of patients.Methods:A total of 108 patients with advanced NSCLC in Suqian Hospital of Nanjing Drum Tower Hospital Group from February 2019 to January 2022 were prospectively selected, and they were divided into osimertinib combined with tislelizumab treatment group (study group) and osimertinib treatment group (control group) by random number table method, with 54 cases in each group. Three weeks were 1 cycle. The curative effect was observed after 3 cycles of treatment in both groups. The clinical efficacy, levels of tumor markers, immune function and adverse reactions were compared between the two groups. After 1 year of follow-up, the overall survival (OS) and progression-free survival (PFS) of the two groups were analyzed by Kaplan-Meier method and compared by log-rank test.Results:After 3 cycles of treatment, the disease control rate of the study group was higher than that of the control group [81.48% (44/54) vs. 59.26% (32/54), χ2 = 6.40, P = 0.011], and the objective remission rate of the study group was higher than that of the control group [57.41% (31/54) vs. 37.04% (20/54), χ2 = 4.50, P = 0.034]. Before treatment, the differences in the levels of cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), squamous cell carcinoma antigen (SCC-Ag) and tissue polypeptide antigen (TPA) between the two groups were not statistically significant (all P > 0.05), and after treatment, the levels of tumor markers were lower than those before treatment in both groups (all P < 0.05), and they were lower in the study group than those in the control group (all P < 0.05). Before treatment, there were no statistically significant differences in the proportions of CD3 + T cells, CD4 + T cells and CD8 + T cells between the two groups (all P > 0.05), and after treatment, the proportions of CD3 + T cells and CD4 + T cells were higher than those before treatment in both groups (both P < 0.05), and they were higher in the study group than those in the control group (both P < 0.001), and the proportion of CD8 + T cells before treatment in both groups was lower than that after treatment ( P < 0.05), and it was lower in the study group than that in the control group ( P < 0.001). The differences in the incidence of neutropenia, leukopenia, immune-associated pneumonia, and liver function injury between the two groups were not statistically significant (all P > 0.05). At 1 year of follow-up, there was 1 case of loss of follow-up in the study group and 2 cases of loss of follow-up in the control group, with a follow-up rate of 97.22% (105/108); there were 9 deaths in the study group with an OS rate of 83.02% and 20 deaths in the control group with an OS rate of 61.54%. OS and PFS in the study group were better than those in the control group [median OS time: 11 months (95% CI 6-11 months) vs. 8 months (95% CI 3-11 months), χ2 = 12.32, P < 0.001; median PFS time: 9 months (95% CI 4-11 months) vs. 5 months (95% CI 4-11 months), χ2 = 6.84, P < 0.001]. Conclusions:Osimertinib combined with tislelizumab can reduce the level of tumor markers and improve immune function in patients with advanced NSCLC with good short-term efficacy, and it doesn't increase the adverse effects and can result in a survival benefit.

Objective:To analyze the effect of vitrectomy combined with internal limiting membrane (ILM) peeling on the prevention of post-vitrectomy epiretinal membrane (ERM) in macular-off rhegmatogenous retinal detachment (RRD) and its influence on visual outcomes.Methods:A cohort study was conducted.Seventy-four patients (74 eyes) with macular-off RRD, who realized retinal reattachment after vitrectomy and silicone oil tamponade from January 2015 to January 2018 in Baoding NO.1 Central Hospital, were enrolled.The patients were divided into the non-ILM peeling group (36 cases, 36 eyes) and ILM peeling group (38 cases, 38 eyes) according to whether they received ILM peeling or not.The patients underwent silicone oil removal within 3 to 5 months after the surgery.Best corrected visual acuity (BCVA), slit-lamp microscopy, indirect ophthalmoscopy, fundus photography and optical coherence tomography (OCT) were examined before and at 1, 6 and 12 months after the surgery.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Baoding NO.1 Central Hospital (No.[2019]042). Written informed consent was obtained from each patient.Results:There was no ERM found in the two groups at 1 month after the operation.There were 3 eyes (8.33%) with ERM in the non-ILM peeling group and 2 eyes (5.26%) in the ILM peeling group at 6 months after the operation, with no statistically significant difference between them ( P=0.067). There were 9 eyes (25.00%) with ERM in the non-ILM peeling group and 4 eyes (10.53%) in the ILM peeling group at 12 months postoperatively, with no statistically significant difference between them ( χ2=2.674, P=0.102). There was a significant difference in BCVA between before and after the operation in the two groups ( Ftime=31.692, P<0.001). Postoperative 1-, 6-and 12-month BCVA were all significantly better than the preoperative BCVA in the two groups (all at P<0.05). There was no significant difference in BCVA between the two groups ( Fgroup=0.117, P=0.773). OCT images showed that there were 25 eyes (77.78%) and 30 eyes (78.95%) with the intact ellipsoid zone in the non-ILM peeling group and ILM peeling group at 12 months after the operation, respectively, with no statistically significant difference between them ( χ2=0.875, P=0.350). Conclusions:Compared with vitrectomy alone, the vitrectomy combined with ILM peeling does not show better efficacy in the prevention of ERM occurrence in macula-off RRD patients and has no obvious influence on postoperative visual acuity.

Objective:To evaluate the changes of metamorphopsia in patients with rhegmatogenous retinal detachment (RRD) who underwent primary vitrectomy and to analyze the correlation between macular microstructure changes and metamorphopsia.Methods:It was a retrospective clinical study. From January 2017 to January 2019, 57 patients (57 eyes) with RRD were examined and diagnosed in the Department of Ophthalmology of Baoding First Central Hospital were enrolled in this study. All patients underwent 23G PPV. All patients had retinal anatomical reduction after the first PPV. The best corrected visual acuity (BCVA), intraocular pressure, slit-lamp microscope, indirect ophthalmoscope, changes of metamorphopsia, and optical coherence tomography (OCT) were examined before PPV and 1, 6, 12 months after the operation. The BCVA examination was performed using the international standard visual acuity chart, which was converted into a logarithm of the minimum angle of resolution (logMAR) BCVA for the record. The macular fovea retinal thickness (CRT) was measured by Carl Zeiss Cirrus HD-OCT5000 instrument from Carl Zeiss Company, Germany, and the microstructural changes in the macular area were recorded, including the presence of the anterior macular membrane (ERM), cystic macular edema (CME), subretinal fluid (SRF), and the integrity of the ellipsoid zone (EZ) and outer membrane (ELM). The value of metamorphopsia (M value) was measured by the M-Chart table. The changes of BCVA, M value, and the microstructure of the macular area before and after operation were analyzed. The correlation between BCVA and M value was analyzed by Pearson correlation. Spearman correlation analysis was used to analyze the correlation between the changes of macular microstructure and BCVA and M values.Results:The mean logMAR BCVA before the operation was 1.15±0.43. At 1, 6, and 12 months after the operation, the mean logMAR BCVA was 0.62±0.17, 0.39±0.18, and 0.34±0.13, respectively. The visual acuity improved significantly after operation compared with before operation, and the difference was statistically significant ( F=119.731, P=0.000). The mean CRT before the operation was 476.0±104.1 μm. At 1, 6, and 12 months after the operation, the average CRT were 299.8±29.9, 272.2±17.8, and 261.0±19.3 μm, respectively. The average CRT after the operation was significantly lower than those before the operation ( F=185.518, P=0.000). At 1, 6, and 12 months after the operation, the mean M values were 0.62±0.54, 0.43±0.41, and 0.32±0.36, respectively; the difference was statistically significant ( F=6.568, P=0.020). After the operation, 48 eyes (84.2%, 48/57) had microstructural abnormalities in the macular area, including EZ and ELM integrity disruption, SRF, CME, and ERM. Correlation analysis showed that M value was significantly positively correlated with BCVA, CRT, and SRF height before operation ( r/ rs=0.672, 0.385, 0.932; P<0.05). There was no correlation between M value and BCVA ( r/ rs=0.503), EZ and ELM integrity ( r/ rs=0.497, 0.472), SRF ( r/ rs=0.416), CME ( r/ rs=0.821) and ERM ( r/ rs=0.632) after operation ( P>0.05). Conclusions:The BCVA is significantly increased and the metamorphopsia is improved after anatomically successful RRD surgery. Postoperative M value is highly correlated with preoperative BCVA, CRT, and SRF.

Objective:To observe the effect of intravitreal injection of anti-vascular endothelial growth factor drugs on the subfoveal choroid thickness (SFCT) of patients with retinal vein occlusion (RVO) and macular edema (ME).Methods:A prospective clinical study. From January 2017 to January 2019, 59 monocular RVO-ME patients with 59 eyes diagnosed in the eye examination of The First Central Hospital of Baoding were included in the study. Among them, there were 31 males with 31 eyes and 28 females with 28 eyes; the average age was 57.4±10.3 years old. The course of the disease was 5 days to 1 month, all of whom had the first-onset disease. Branch retinal vein occlusion (BRVO) was found in 35 eyes (BRVO-ME group); non-ischemic central retinal vein occlusion (CRVO) was found in 24 eyes (CRVO-ME group). Best corrected visual acuity (BCVA) and frequency domain optical coherence tomography (OCT) were performed. The BCVA examination was carried out using the international standard visual acuity chart, which was converted into the logarithmic minimum angle of resolution (logMAR) visual acuity during statistics. The Cirrus HD-OCT 5000 instrument from Carl Zeiss company of Germany was used to measure the central macular thickness (CMT) and SFCT. All eyes were treated with intravitreal injection of anti-vascular endothelial growth factor drugs. The follow-up time after treatment was 6 months, and the changes of BCVA, CMT and SFCT of eyes before treatment and 2 weeks after treatment were compared and observed, as well as the occurrence of treatment-related complications. The comparison of BCVA, CMT, and SFCT at different times before and after treatment were adopted repeated measures analysis of variance; pairwise comparison of differences at different time points adopts the least significant difference t test. Results:Before treatment, the average logMAR BCVA and CMT of RVO-ME eyes were 0.92±0.46 and 604.71±169.35 μm, respectively. At 2 weeks, 1, 3, and 6 months after treatment, the average logMAR BCVA of the affected eye was significantly improved compared with that before treatment, and the CMT was significantly decreased. The difference was statistically significant ( F=55.664, 59.518; P<0.05). Before treatment, the average SFCT of the affected eye and the contralateral eye of RVO-ME patients were 306.3±65.8 and 241.3±59.8 μm, respectively. The SFCT of the affected eye was significantly thicker than that of the contralateral healthy eye, and the difference was statistically significant ( t=25.772, P<0.05). At 2 weeks, 1, 3, and 6 months after treatment, the average SFCT of the eyes were 267.7±81.4, 252.3±57.3, 239.2±46.5, 240.6±48.3 μm, respectively. Compared with before treatment, treatment SFCT decreased significantly at different times afterwards, and the difference was statistically significant ( F=924.341, P<0.001). There was no significant difference in SFCT between CRVO-ME group and BRVO-ME group at 2 weeks, 1, 3, and 6 months after treatment ( P>0.05). No complications such as endophthalmitis, cataract progression and neovascular glaucoma occurred during the follow-up period of all eyes. Conclusion:The SFCT of eyes with short course of disease and first-onset RVO-ME is thickened; anti-VEGF drug treatment can effectively reduce SFCT, improve ME, and increase BCVA.
