Objective:To observe and analyze the correlation between ectopic foveal inner layer (EIFL) and the EIFL-based idiopathic epiretinal membrane (ERM) staging system and the anatomic and functional prognosis of ERM eyes post pars plana vitrectomy (PPV).Methods:A retrospective study. From January 1, 2020 to October 30, 2023, 345 eyes of 330 patients diagnosed with idiopathic ERM in Department of Ophthalmology of Peking University People's Hospital and treated with standard transciliary flat three-channel 25G PPV combined with ERM and internal limiting membrane exfoliation were included in the study. Among them, 96 were males (111 eyes) and 234 were females (234 eyes). The mean age was (66.8±7.7) years. All study eyes received standard three-port 25G PPV combined with ERM and internal limiting membrane peeling. All study eyes underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examinations. BCVA was performed using a standard logarithmic visual acuity chart and converted to logarithm of the minimum angle of resolution visual acuity for statistical analysis. EIFL thickness and central foveal thickness (CFT) on OCT were measured. ERM eyes were grouped into stage Ⅰ, Ⅱ, Ⅲ and Ⅳ according to ERM staging scheme based on EIFL; disorganization of the retinal inner layers (DRIL) of study eyes were assessed and grouped into no, mild and severe groups. The correlation between ERM staging as well as EIFL thickness and the anatomical and functional prognosis 6 months post-PPV were analyzed.Results:Among 345 study eyes, 12, 87, 174 and 72 eyes were stage Ⅰ-Ⅳ ERM respectively, 63 with no DRIL, 216 with mild DRIL and 66 with severe DRIL. Among the 153 eyes with macular edema, the edema subsided in 66 eyes (43.1%, 66/153) 6 months after the operation. Eighty-seven eyes (56.9%, 87/153) did not regress. The edema subsided 6 months after the operation was not significantly correlated with the ERM stage before the operation ( χ2=3.331, R=?0.145, P=0.304) or the degree of DRIL ( χ2=0.655, R=?0.108, P=0.445). The results of the correlation analysis showed that logMAR BCVA 6 months after the surgery was positively correlated with the degree of DRIL before the surgery ( Tau-b=0.236), ERM stage ( Tau-b=0.194), CFT ( r=0.383), and EIFL thickness ( r=0.317) ( P<0.05). There was no significant correlation with the thickness of the outer nuclear layer before the operation ( r=0.004, P>0.05). Preoperative ERM stage ( Tau-b=0.303, P<0.001) and DRIL severity ( Tau-b= 0.238, P=0.001) were positively correlated with CFT at 6 months after surgery. Conclusion:The ERM stage and EIFL thickness before the operation are positively correlated with logMAR BCVA and CFT 6 months after the operation.

Objective:To analyze the infection status and influencing factors of Helicobacter pylori ( Hp) in healthy children. Methods:This is a cross-sectional study. The data of 684 children aged 3 to 14 years who underwent the 13C urea breath test in the Health Management Center of Fuwai Central China Cardiovascular Hospital from December 2022 to December 2023 were retrospectively collected, and 652 of them who met the criteria were included in the analysis. According to whether they were infected with Hp, the children were divided into the infected group and the non-infected group, and the differences in age, gender, living habits and other aspects between the two groups were compared. Multivariate logistic regression analysis was used to analyze the factors influencing Hp infection. Results:Among the 652 children, there were 134 cases in the infected group and 518 cases in the non-infected group, with an Hp infection rate of 20.6%. The Hp infection rate showed an upward tendency with age. The Hp infection rates in children aged 3 to 5 years, 6 to 11 years, and 12 to 14 years were 12.6%, 22.0%, and 25.2% respectively ( χ 2=9.862, P=0.007). Univariate analysis showed that the proportions of Hp infection were higher in children who never washed their hands, ate in school cafeterias, did not have separate meals, were fed with chewed food, bit their fingers or toys, lived with relatives who had a history of gastrointestinal diseases, had low family income, had parents with low educational level, and were mixed/artificially fed during infancy, which were 26.1%, 24.1%, 25.4%, 25.7%, 26.0%, 25.8%, 25.1%, 23.7%, and 23.6% respectively (all P<0.05). Multivariate analysis showed that separate meals, good handwashing habits, and high family income were protective factors against Hp infection ( OR=0.689, 0.779, 0.602, P=0.004, 0.013, 0.019), while feeding with chewed food was a risk factor for Hp infection ( OR=1.998, P=0.001). Conclusion:The Hp infection rate of children undergoing health examination in Zhengzhou is at low level, and the main influencing factors are separate meals, handwashing habits, feeding with chewed food, and family income.

Objective:To explore the correlation between serum uric acid/high-density lipoprotein cholesterol ratio (UHR) and the risk of hypertension in elderly physical examination populations.Methods:This study was a cross-sectional study. A total of 1 028 patients aged≥60 years who underwent physical examinations at the Health Management Center of Fuwai Central China Cardiovascular Hospital from September 2023 to February 2024 were included in this study. The general demographic data, past medical history, physical examination and laboratory examination indicators of the physical examiners were collected, and according to whether they had hypertension or not, they were divided into hypertension group (390 cases) and non-hypertension group (638 cases), and all UHR values were arranged from small to large, and the UHR was divided into three groups by tertiles of UHR, and the general data and blood biochemical indexes between the groups were compared. Spearman rank correlation was used to analyze the correlation between UHR level and body mass index, total cholesterol, triglyceride and other indexes in the elderly population. Logistic regression was used to explore the relationship between UHR level and hypertension in the elderly population, and the stratification analysis of the physical examination population was carried out according to diabetes, coronary heart disease and dyslipidemia, and the interaction test between groups was carried out.Results:Among the 1 028 geriatric physical examination cases, 580 (56.4%) were males and 448 (43.6%) were females, aged (66.7±5.8) years. UHR levels were higher in the hypertensive group compared to the non-hypertensive group [248.88 (191.19, 322.25) vs 213.52 (165.94, 275.29); Z=-5.445, P<0.05]. With the increase of UHR level, the detection rate of hypertension in the elderly population increased (accounted for 27.8%, 38.2% and 47.8%, respectively; χ2=29.211, P<0.05). Spearman rank correlation analysis showed that UHR was positively correlated with body mass index, triglycerides, serum uric acid, serum creatinine and fasting blood glucose ( r=0.318, 0.334, 0.774, 0.474, 0.080; all P<0.05), and negatively correlated with total cholesterol, glomerular filtration rate and low-density lipoprotein cholesterol ( r=-0.239, -0.303, -0.154; all P<0.05). When the confounding factors were not adjusted (model 1), the risk of hypertension in high UHR group was 2.382 times higher than that in low UHR group and 1.607 times higher than that in medium UHR group; after adjusting for all confounding factors such as age, gender, body mass index, systolic blood pressure, diastolic blood pressure, junior high school education or below, smoking, alcohol consumption, glomerular filtration rate, etc., the risk of hypertension in the high-level UHR group was 1.732 times higher than that in the low-level UHR group (95% CI: 1.139-2.635) ( P<0.05). The elderly physical examination population was further stratified according to whether there was diabetes, dyslipidemia and coronary heart disease, and it was found that there was no interaction between UHR and diabetes, dyslipidemia and coronary heart disease on the prevalence of hypertension (all P>0.05). Conclusions:Hypertension detection rate increases with higher UHR levels. UHR is closely related to the incidence of hypertension in the elderly population.

Objective:To explore the predictive value of triglyceride-glucose (TyG) index and residual cholesterol (RC) for intracranial artery stenosis (ICAS) in a physical examination population with H-type hypertension.Methods:It was a cross-sectional study. A total of 3 452 individuals with H-type hypertension who underwent physical examinations at the Health Management Center of Fuwai Central China Cardiovascular Hospital from September 2021 to March 2025 were continuously selected as the research subjects. Magnetic resonance angiography was used to assess intracranial artery stenosis, and the subjects were divided into a non-ICAS group (2 018 cases) and ICAS group (1 344 cases). The clinical indicators of the two groups were collected, including past medical history, height, weight, waist-hip ratio, smoking history, drinking history, blood pressure, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting plasma glucose and homocysteine. The logistic regression analysis was used to analyze the related factors of ICAS in the physical examination population with H-type hypertension. The predictive value of TyG index and RC for the occurrence of ICAS in the physical examination population with H-type hypertension was evaluated by using the receiver operating characteristic (ROC) curve.Results:Among the 3 452 physical examination individuals with H-type hypertension included in the analysis, there were 2 285 males (66.2%) and 1 167 females (33.8%), with an age of (41.36±8.99) years. The levels of smoking history, drinking history, overweight/obesity, increased waist-to-hip ratio, age, triglycerides, homocysteine, TyG index and RC in the ICAS group were all higher than those in the non-ICAS group [66.6% vs 36.8%, 70.2% vs 38.0%, 70.0% vs 48.5%, 76.2% vs 40.6%, (45.53±10.32) vs (39.59±9.38) years, 1.79 (1.35, 2.97) vs 1.42 (0.91, 2.53) mmol/L, 22.15 (19.76, 24.89) vs 18.52 (16.26, 20.66) μmol/L, 8.89 (8.62, 9.75) vs 7.85 (7.24, 8.47), 0.84 (0.50, 1.60) vs 0.66 (0.42, 1.04) mmol/L], the level of high-density lipoprotein cholesterol was lower than that in the non-ICAS group [1.03 (0.91, 1.24) vs 1.26 (0.99, 1.52) mmol/L](all P<0.05). Spearman correlation analysis showed that ICAS was positively correlated with body mass index, waist-hip ratio, total cholesterol, TyG index and RC ( r=0.167, 0.219, 0.224, 2.536, 0.379), and it was negatively correlated with high-density lipoprotein cholesterol ( r=-0.314) (all P<0.05). The logistic regression analysis showed that TyG index ( OR=10.293, 95% CI: 5.128-21.614) and RC ( OR=1.045, 95% CI: 0.139-1.328) were both positively correlated with ICAS (both P<0.05). The ROC curve analysis showed that the area under the ROC curve of TyG index combined with RC for predicting ICAS in the physical examination population with H-type hypertension was 0.750, with a sensitivity of 80.8% and a specificity of 73.2%, which was superior to predictive power of TyG index or RC alone (both P<0.05). Conclusion:Both TyG index and RC have good predictive value for ICAS in the physical examination population with H-type hypertension, and combination of both has a higher predictive performance.

Objective:To analyze the correlation between poor sleep status in late pregnancy and postpartum depression and anxiety.Methods:In this prospective cohort study, a total of 401 women in early pregnancy were consecutively enrolled at Beijing Tian Tan Hospital, Capital Medical University, from December 2020 to April 2021. The Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) were used to assess the sleep status in late pregnancy. The Edinburgh Postnatal Depression Scale (EPDS) and the 7-item Generalized Anxiety Disorder Scale (GAD-7) were used to assess the emotional status in late pregnancy and 6 weeks after delivery. During the follow-up, 123 subjects did not complete the sleep and emotional assessment in late pregnancy, 77 subjects did not complete the postpartum emotional assessment, and 201 cases were finally included in the study. Multivariate logistic regression analysis was used to analyze the correlation between poor sleep status in late pregnancy and postpartum depression and anxiety.Results:Among 201 women in early pregnancy included in the analysis, the detection rate of postpartum depression and anxiety was 15.4% (31/201) and 27.4% (55/201), respectively. Poor sleep quality ( OR=2.49, 95% CI: 1.02-6.07), difficulty falling asleep ( OR=6.74, 95% CI: 2.31-19.70), and excessive daytime sleepiness ( OR=6.34, 95% CI: 2.08-19.32) in late pregnancy were positively correlated with postpartum depression (all P0.05). Poor sleep quality ( OR=3.89, 95% CI: 1.81-8.40), difficulty falling asleep ( OR=6.75, 95% CI: 2.43-18.77), short-time sleep ( OR=2.89, 95% CI: 1.36-6.11), fragmented sleep ( OR=5.69, 95% CI: 2.27-14.28) and excessive daytime sleepiness ( OR=3.07, 95% CI: 1.07-8.78) in late pregnancy were positive correlation factors for postpartum anxiety (all P0.05). Conclusions:Poor sleep status in late pregnancy is associated with postpartum depression and anxiety. Strengthening screening and management of poor sleep status in late pregnancy may help maintain healthy postpartum emotion.

Objective:To analyze the correlation between serum uric acid-to-high-density lipoprotein cholesterol ratio (UHR) and risk of all-cause death or cardiovascular disease (CVD) death among urban and rural elderly in Beijing.Methods:Based on the Beijing Healthy Aging Cohort Study, 9 022 participants with complete baseline data were enrolled, and their survival and death outcomes were followed up. Multivariable Cox proportional hazard regression model were used to analyze the associations between the UHR level and the risks of all-cause mortality and CVD mortality.Results:As of March 31, 2021, the median follow-up time M( Q1, Q3) was 6.18 (5.36, 6.75) years. There were 1 166 all-deaths, with a death density of 19.26 per 1 000 person-years, and 562 CVD deaths, with a death density of 9.28 per 1 000 person-years. After adjusting sociodemographic characteristics and lifestyle factors, multivariable Cox proportional hazard regression model showed that the risk of all-cause mortality increased by 3% ( HR=1.03, 95% CI: 1.02-1.04) and the risk of CVD mortality increased by 4% ( HR=1.04, 95% CI: 1.02-1.06) for every 1% increase in UHR. Compared with the T1 group of UHR tertiles, the T3 group had a 42% increase in the risk of all-cause death ( HR=1.42, 95% CI: 1.22-1.66) and a 53% increase in the risk of CVD death ( HR=1.53, 95% CI: 1.21-1.94). Conclusions:The UHR level is significantly associated with the risks of all-cause mortality and CVD mortality among urban and rural older adults in Beijing. The UHR level may be one of the potential predictors of death risk in community-dwelling older adults.

Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.
