Intravitreal injection of anti-vascular endothelial growth factor(VEGF)agents has become the primary treatment for macular edema associated with retinal vascular disease such as diabetic retinopathy and retinal vein occlusion, but there are limitations such as variable treatment efficacy and insufficient durability of therapeutic effects. As the first bispecific antibody applied in ophthalmic treatment, Faricimab achieves favorable outcomes by simultaneously targeting both VEGF-A and angiopoietin-2(Ang-2)pathways. Based on evidence from recent clinical trials and real-world studies, this article reviews the research progress on Faricimab for the treatment of diabetic macular edema(DME), retinal vein occlusion-associated macular edema(RVO-ME)and refractory macular edema compared to the therapeutic effects of other agents. Additionally, based on Faricimab's safety characteristics and future potential, its therapeutic prospects for macular edema associated with retinal vascular diseases are discussed. This review aims to provide evidence-based references for optimizing clinical treatment strategies, thereby contributing to mitigating the risk of vision loss due to macular edema.

Objective:To investigate the efficacy of continuous irrigation and drainage combined with lesion debridement surgery in the treatment of purulent bone and joint infections in children.Methods:A case-control study was conducted to retrospectively analyze the clinical data of 76 children with purulent bone and joint infections who received treatment at Hangzhou Children's Hospital from January 2021 to October 2022. Based on different treatment methods, these children were divided into a control group and an observation group, with 38 cases in each group. The control group received lesion debridement surgery, while the observation group underwent continuous irrigation and drainage combined with lesion debridement surgery. The clinical outcomes of the two groups were compared.Results:The total response rate in the observation group was 97.37% (37/38), which was significantly higher than that in the control group [76.32% (29/38), χ2 = 7.36, P < 0.05]. After treatment, the white blood cell count, erythrocyte sedimentation rate, and percentage of neutrophils in the observation group were (4.32 ± 0.95) × 10 9/L, (14.20 ± 2.50) mm/h, and (52.12 ± 8.45)%, respectively, all of which were significantly lower than those in the control group [(5.68 ± 1.02) × 10 9/L, (22.35 ± 3.35) mm/h, and (66.65 ± 6.20)%, t = 6.01, 12.01, 8.54, all P < 0.05]. The levels of interleukin-6, C-reactive protein, procalcitonin, and tumor necrosis factor-α in the observation group were (5.20 ± 1.02) ng/L, (8.20 ± 1.11) mg/L, (0.80 ± 0.12) μg/L, and (3.20 ± 1.02) ng/L, respectively, which were significantly lower than those in the control group [(8.12 ± 1.10) ng/L, (14.34 ± 2.20) mg/L, (1.12 ± 0.20) μg/L, and (7.50 ± 1.12) ng/L, t = 11.99, 15.36, 8.45, 17.49, all P < 0.05). At 1 week, 1 month, and 3 months after treatment, the Visual Analog Scale scores in the observation group were significantly lower than those in the control group ( t = 3.14, 2.33, 11.36, all P < 0.05). The recurrence rate in the observation group was significantly lower than that in the control group [2.63% (1/38) vs. 21.05% (8/38), χ2= 4.53, P < 0.05). Conclusion:Continuous irrigation and drainage combined with lesion debridement surgery is more effective for treating purulent bone and joint infections in children than lesion debridement surgery alone. This combined therapy can more effectively reduce inflammatory responses, alleviate pain, and lead to a lower recurrence rate.

Previous studies have revealed that patients with hypertrophic cardiomyopathy (HCM) exhibit differences in symptom severity and prognosis, indicating potential HCM subtypes among these patients. Here, 793 patients with HCM were recruited at an average follow-up of 32.78 ± 27.58 months to identify potential HCM subtypes by performing consensus clustering on the basis of their echocardiography features. Furthermore, we proposed a systematic method for illustrating the relationship between the phenotype and genotype of each HCM subtype by using machine learning modeling and interactome network detection techniques based on whole-exome sequencing data. Another independent cohort that consisted of 414 patients with HCM was recruited to replicate the findings. Consequently, two subtypes characterized by different clinical outcomes were identified in HCM. Patients with subtype 2 presented asymmetric septal hypertrophy associated with a stable course, while those with subtype 1 displayed left ventricular systolic dysfunction and aggressive progression. Machine learning modeling based on personal whole-exome data identified 46 genes with mutation burden that could accurately predict subtype propensities. Furthermore, the patients in another cohort predicted as subtype 1 by the 46-gene model presented increased left ventricular end-diastolic diameter and reduced left ventricular ejection fraction. By employing echocardiography and genetic screening for the 46 genes, HCM can be classified into two subtypes with distinct clinical outcomes.

The effect of living kidney transplantation between identical twins is satisfied, but it is rarely reported. From October 2019 to February 2021, two recipients received kidney transplantation from their twin sisters in the Second Xiangya Hospital of Central South University. The primary disease of the two recipients was acute glomerulonephritis in 1 case and diabetic nephropathy in 1 case. Two recipients received tacrolimus/cyclosporine+ mortemycophenol ester+ methylprednisolone after surgery. The patients were followed up for 3.0 and 1.5 years, respectively, with renal function recovering well.

BACKGROUND: Children and adolescents are in the growth and development stage, so the use of the same reconstruction methods as adults is easy to induce complications including limb length differences, high graft failure rate and re-surgical intervention. Simultaneously, the occurrence of osteoarthritis will also be advanced. OBJECTIVE: To explore the anatomical characteristics of the anterior cruciate ligament between children, adolescents and adults on MRI, and to provide an anatomical basis for the reconstruction of the anterior cruciate ligament in children and adolescents. METHODS: A retrospective analysis of patients undergoing knee MRI examination in Qingdao Municipal Hospital from October 2016 to October 2018 was conducted. These patients were divided into child and adolescent group and adult group (n=48 per group). The angle between the anterior cruciate ligament and the tibia and femur on the sagittal plane and the position of the anterior cruciate ligament tibial insertion, the angle between the anterior cruciate ligament and the tibia on the coronal plane, the tibial insertion of the anterior cruciate ligament and femur, and the position of the femur stop point on the axial position were measured in both groups. The data obtained from the measurement of the anterior cruciate ligament of children and adolescents were processed. The growth curves of the shape and position of the anterior cruciate ligament of children and adolescents were drawn, and the law of its growth changes was analyzed. RESULTS AND CONCLUSION: (1) The angle between the sagittal plane of the anterior cruciate ligament and the femur (t=﹣2.906, P<0.05), the angle between the sagittal plane of the anterior cruciate ligament and the tibia (t=﹣10.280, P < 0.05), the anterior cruciate ligament angle between the coronal plane and the tibia (t=﹣5.714, P<0.05) were smaller in the child and adolescent group than those of the adult group, and the difference was significant. (2) The ratio of the tibia coronal plane of the anterior cruciate ligament (t=﹣7.263, P < 0.05) and the ratio of the anterior cruciate ligament and femur axial plane (t=﹣7.378, P < 0.05) were lower in the child and adolescent group than those of the adult group, and the difference was significant. (3) There was no significant difference in the anterior cruciate ligament and tibia sagittal plane ratio (t=﹣1.588, P>0.05) and anterior cruciate ligament and femoral coronal surface ratio (t=﹣1.647, P>0.05) between the child and adolescent group and the adult group. (4) The growth curve results showed that during the growth and development, the angle between the anterior cruciate ligament and the femur and tibia on the sagittal plane and the angle with the tibia on the coronal plane changed from small to large (P<0.05). The relative position of the tibial insertion in the coronal position changed from small to large, which indicates that during the growth and development, the tibial insertion moved from inside to outside relative to the inside of the tibial plateau on the coronal plane (P < 0.05). (5) The relative position of femoral insertion in the axial position changed from small to large, suggesting that during the growth and development, the femoral insertion moved from the outside to the inside relative to the lateral femoral condyle (P<0.05). (6) There was no significant difference in the tibial insertion and the femoral insertion between the child and adolescent group and adult group (P>0.05).
