Objective:To compare and observe the visual acuity and ocular anatomical outcome of different subtypes in open-globe injury (OGI) Ⅲ.Methods:A retrospective study. A total of 187 eyes of 187 patients with OGI involving zone Ⅲ who were admitted to the Department of Ophthalmology of The First Affiliated Hospital of Army Medical University from January 2020 to December 2023 were included in the study. According to the 2022 International Globe and Adnexal Trauma Epidemiology Study groups consensus, zone Ⅲ was further divided into Ⅲa zone (5-8 mm posterior to the limbus) and Ⅲb zone (>8 mm posterior to the limbus), with 58 eyes (31%, 58/187) in group Ⅲa and 129 eyes (69%, 129/187) in group Ⅲb. Best corrected visual acuity (BCVA) was examined using the international standard decimal visual acuity chart, converted into the logarithm of the minimum angle of resolution (logMAR) visual acuity when recorded. The injured zone, initial visual acuity, final visual acuity, retinal detachment (RD), uveal prolapse, and proliferative vitreoretinopathy (PVR) were collected. The follow-up time after surgery ≥ 6 months. The final visual acuity and anatomical prognosis of the two groups were observed. Silicone oil dependence, phthisis, and enucleation were defined as poor anatomical outcomes. Multiple linear regression analysis was performed to analyze the impact of zone Ⅲb of OGI on the final visual acuity.Results:At the 6-month follow-up, the logMAR BCVA of group Ⅲa and group Ⅲb was 1.49±1.0 and 2.51±0.85; there was a statistically significant difference in the logMAR BCVA between the two groups ( t=-2.736, P<0.05). Compared with group Ⅲa, the proportion with light perception in group Ⅲb was higher, and the proportions with visual acuity of hand movement, counting fingers, and >0.01 were lower, and the differences were all statistically significant ( P<0.05). Compared with group Ⅲa, RD and PVR were more likely to occur in group Ⅲb, and the differences were all statistically significant ( χ2= 16.696, 8.697; P<0.05). Among the affected eyes in group Ⅲa and group Ⅲb, there were 14 eyes (24.1%, 14/58) and 95 eyes (73.6%, 95/129) with poor final anatomical outcomes respectively; the incidence of poor final anatomical outcomes in group Ⅲb was higher, and the difference was statistically significant ( χ2= 40.332, P<0.01). The results of multiple linear regression analysis showed that initial visual acuity, RD, and uveal prolapse were independent risk factors affecting the final visual acuity (odds ratio=2.407, 4.162, 3.413; P<0.05). Conclusions:Patients with OGI in zone Ⅲb have a worse visual prognosis and a higher incidence of poor anatomical outcomes. The subclassification of zone Ⅲ is helpful for better predicting the prognosis of OGI clinically.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Journal of Preventive Medicine 2024;36(6):518-522
Objective:
To examine the causal relationships between obesity, peripheral blood lipid indicators and non-small cell lung cancer (NSCLC) using Mendelian randomization (MR) method, so as to provide the basis for developing NSCLC prevention and control strategies.
Methods:
Genetic variation data of three obesity evaluation indicators, including body mass index (BMI), body fat ratio (BFR) and waist-to-hip ratio (WHR), and seven peripheral blood lipid indicators, including triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB) and lipoprotein a [LP (a)] were collected through genome-wide association studies (GWAS) and related public databases. Potential causal relationships between obesity, peripheral blood lipid indicators and NSCLC were analyzed using inverse-variance weighted (IVW) method and multivariable MR analysis upon a random effect model. Heterogeneity and horizontal pleiotropy of instrumental variables were evaluated using Cochran's Q test and MR-Egger regression.
Results:
There was statistically association between BMI with NSCLC (OR=1.256, 95%CI: 1.087-1.451); there were no statistically associations between BFR, WHR, seven peripheral blood lipid indicators and NSCLC (all P>0.005). There was heterogeneity in the association between BMI, BFR, WHR, TG, HDL-C and NSCLC (all P<0.05); no horizontal pleiotropy of instrumental variables was found (all P>0.05). There was no statistically association between BMI and NSCLC after adjusting BFR (OR=1.367, 95%CI: 0.878-2.128); there was still statistically association between BMI and NSCLC after adjusting WHR and peripheral blood lipid indicators (both P<0.05).
Conclusions
The increase of BMI is associated with the increased risk of NSCLC incidence. BFR may be a potential influencing factor for the association between BMI and NSCLC.

Influenza virus causes serious threat to human life and health. Due to the inherent high variability of influenza virus, clinically resistant mutant strains of currently approved anti-influenza virus drugs have emerged. Therefore, it is urgent to develop antiviral drugs with new targets or mechanisms of action. RNA-dependent RNA polymerase is directly responsible for viral RNA transcription and replication, and plays key roles in the viral life cycle, which is considered an important target of anti-influenza drug design. From the point of view of medicinal chemistry, this review summarizes current advances in diverse small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase, hoping to provide valuable reference for development of novel antiviral drugs.
