Fracture of humeral capitellum (FHC) in children is often detected on the coronal plane of the distal humerus.It is an intra-articular fracture, often a Salter-Harris type Ⅲ epiphyseal fracture, which is extremely rare in clinical practice and accounts for only about 1% of elbow fractures in children.This type of fracture tends to extend medially involving the trochlea, so it is also known as capitellar trochlea fracture.The rarity of this fracture makes it difficult to differentiate it from other elbow fractures on X-ray, which finally leads to miss-diagnosis or misdiagnosis as epicondylar humerus fracture or intercondylar fracture, etc.Since FHC is an intra-articular and epiphyseal fracture, inappropriate treatment will results in irreversible consequences, so the diagnosis and treatment of FHC in children are challenging.Currently, there are few studies on FHC in children, and most of related studies are case reports.Therefore, the classification and treatment of FHC in children are performed based on only the experience of FHC treatment in adults.Incisional reduction and internal fixation is the preferred treatment for most FHC children, but the efficacy of this treatment lacks the support of controlled studies with a large sample size.The mechanism of injury, staging, diagnosis, treatment, postoperative rehabilitation, and complications of pediatric FHC were reviewed in this paper to improve clinicians' understanding of pediatric FHC.

Objective To explore the causal relationship between myopia and specific immune cells through Mende-lian randomization(MR)analysis.Methods Data were mined from the Genome-Wide Association Studies(GWAS)data-base,and 731 immune cell characteristics were selected as exposure factors and myopia as the outcome factor.A signifi-cance threshold was established to filter single nucleotide polymorphisms(SNPs)significantly associated with immune cells and myopia,and the influence of weak instrument variable bias was eliminated.The primary analysis method employed was the inverse variance weighted(IVW)approach,supplemented by simple mode,weighted median,weighted mode,and MR-Egger regression for data analysis.The causal relationship between circulating immune cells and myopia was assessed using odds ratios(OR)and 95%confidence intervals.For the SNPs of immune cells that met the hypothesis,Cochran's Q test was used to evaluate heterogeneity,and MR-Egger regression and MR-PRESSO methods were employed to exclude hor-izontal pleiotropy.The leave-one-out analysis was utilized to assess whether significant results were driven by individual SNPs.To avoid reverse causal relationships,myopia was taken as the exposure variable and immune cell phenotypes as outcome variables in the reverse MR analysis.Additionally,multivariate Mendelian randomization(MVMR)was used to e-valuate the causal and independent effects of these immune cells on myopia.Results(1)The results from the two-sam-ple MR IVW method indicated that Memory B cell AC and CD24+CD27+AC(B cells)were protective factors against my-opia.In contrast,Naive CD8br%CD8br(T cells),CD39+CD8br AC(T cells),CD25 on CD39+activated Treg(T cells),PDL-1 on CD 14+CD 16+monocytes and CD80 on myeloid DC were identified as risk factors for myopia.These re-sults are consistent with those of MR-Egger and other methods.MR-Egger regression and MR-PRESSO analyses demonstra-ted that there was no horizontal pleiotropy(P>0.05).(2)The reverse two-sample MR analysis revealed no bidirectional causal relationships between myopia and the aforementioned seven immune cells(all P>0.05).(3)In the MVMR analysis,the significant causal relationship between CD80 on myeloid DC and myopia remained robust after adjusting for potential confounding variables.Conclusion This study reveals the complex causal relationships between various immune pheno-types and myopia through genetic methods,and demonstrates the intricate regulatory patterns of interactions between the immune system and myopia.

ObjectiveTo investigate the effect of Naoqingtong decoction (NQT) on the kidney damage and the inflammatory factors NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain (ASC), cysteinyl aspartate-specific proteinase-1 (Caspase-1), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in spontaneously hypertensive rats (SHRs). MethodsTwenty-four SHRs were randomized into a model group, a low-dose (12.9 g·kg-1·d-1) NQT (NQT-L) group, a high-dose (25.8 g·kg-1·d-1) NQT group (NQT-H), and a captopril (CTP, 20 mg·kg-1·d-1) group, with 6 rats in each group. In addition, 6 homozygous male Wistar-Kyoto rats were used as the control group. The control and model groups were administrated with the same amount of normal saline by gavage for 8 weeks. General behaviors of rats were observed during the intervention period, and the blood pressure was measured periodically. At the end of intervention, the body mass was weighed, and both kidneys were collected and weighed for the calculation of the renal index. Hematoxylin-eosin staining was performed to observe the pathological changes in the kidney tissue. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the expression levels of NLRP3, ASC, Caspase-1, IL-6, and TNF-α in the kidney tissue. ResultsDuring the experiment period, the control group had normal mental status, food intake, and activity, while the model group showed thinning of hair, loss of luster, reduced activity, loss of appetite, fecal adhesion, and irritability, and some of the skin had scratches or blood scabs. The above symptoms were alleviated to different degrees after 8 weeks of NQT administration. An intelligent non-invasive sphygmomanometer was used to measure the tail artery pressure of rats, which showed that the systolic and diastolic blood pressure of rats in the model group was higher than that in the control group (P<0.01). Compared with the model group, drug interventions lowered the systolic and diastolic blood pressure (P<0.05, P<0.01). Compared with the control group, the model group showed severe pathological damage in the kidney tissue, which was alleviated in each drug intervention group. Compared with the control group, the model group showed up-regulated expression levels of NLRP3, ASC, Caspase-1, IL-6, and TNF-α in the kidney tissue (P<0.05, P<0.01). Compared with the model group, the drug intervention groups showed down-regulated expression levels of NLRP3, ASC, Caspase-1, IL-6, and TNF-α in the kidney tissue (P<0.05, P<0.01). ConclusionNQT can lower the blood pressure in SHRs by inhibiting the activation of NLRP3 inflammasomes, suppressing renal inflammation, and ameliorating hypertensive kidney damage.

Objective:To summarize and analyze the clinical features of patients with inflammatory bowel disease (IBD) accompanied by axial spondyloarthritis (ax-SpA) .Methods:A descriptive case series study was conducted. Consecutive IBD patients with ax-SpA admitted to Peking Union Medical College Hospital from January 2012 to December 2023 were enrolled, and the clinical data were collected and analyzed descriptively.Results:A total of 21 IBD patients with ax-SpA were enrolled, including 14 males (66.7%) and 7 females (33.3%). The median age at IBD diagnosis was 29 (24, 42) years. Among them, 10 had ulcerative colitis (UC) and 11 had Crohn's disease (CD). In 11 patients (52.4%), ax-SpA was diagnosed before IBD, while in 7 patients (33.3%), IBD was diagnosed before ax-SpA; the remaining 3 patients (14.3%) were diagnosed simultaneously. Thirteen patients (61.9%) had other extraintestinal manifestations, with 12 involving mucocutaneous manifestations. Nineteen patients including 9 UC and 10 CD were followed up for a median duration of 34 (12, 57) months. Among UC patients, 5 (55.6%) were escalated from conventional therapy to biologics or small-molecule drugs, and 6 (66.7%) developed opportunistic infections. Among CD patients, 3 (30.0%) were escalated to biologic therapy, and 2 (20.0%) developed opportunistic infections. Three patients (15.8%) underwent intestinal resection surgery.Conclusions:IBD patients with ax-SpA are predominantly male, with a similar proportion of UC and CD. There is no clear sequential pattern in the diagnosis timing of IBD and ax-SpA. These patients often present with other extraintestinal manifestations of IBD, primarily mucocutaneous manifestations.
