Objective:To investigate the efficacy of using a single Kocher-Langenbeck approach to improve anterior column screw fixation for the treatment of transverse + posterior wall acetabular fractures.Method:A retrospective analysis was conducted of the data of 21 patients who had been treated with a single Kocher-Langenbeck approach to improve anterior column screw fixation for transverse + posterior wall acetabular fractures at Department of Orthopaedics, Weifang People's Hospital from May 2021 to May 2023. There were 11 males and 10 females with an age of (51.3±15.5) years. The time from injury to surgery was (10.4±3.6) days. The anterior column screw fixation was improved as follows: screws were implanted 1 to 2 cm in front of the apex of the great notch of the external iliac plate of the pelvis to penetrate out at the upper branch root of the pubic ramus, with the whole screw fully located within the bony channel. Such indexes were recorded as surgical time, intraoperative blood loss, intraoperative fluoroscopy frequency for improved placement of anterior column screws, fracture healing time, incidence of complications, and fracture reduction and hip joint function at the last follow-up.Results:For this cohort, surgical time was (120.9±40.7) minutes, intraoperative blood loss (330.2±65.9) mL, and intraoperative fluoroscopy frequency for improved placement of anterior column screws (6.2±2.3) times. The 21 patients were followed up for (21.5±5.9) months. All fractures achieved bony union after (3.2±1.1) months. Incision fat liquefaction occurred in 1 patient after surgery and symptoms of sciatic nerve injury were observed in 2 patients. Follow-ups observed no such complications as loosening or breakage of internal fixators. According to the Matta scoring criteria, the quality of fracture reduction at the last follow-up was evaluated as anatomical reduction in 15 cases, as satisfactory reduction in 4 cases, as acceptable reduction in 2 cases, giving a satisfaction rate of 90.5% (19/21). According to the improved Merle d'Aubigné & Poster scoring criteria, hip function was evaluated as excellent in 16 cases, as good in 2 cases, and as fair in 3 cases, giving an excellent and good rate of 85.7% (18/21).Conclusion:It is effective to use a single Kocher-Langenbeck approach to improve anterior column screw fixation for the treatment of transverse + posterior wall acetabular fractures, showing advantages of reduced surgical time and intraoperative bleeding.

This paper reports a case of hepatoblastoma that is inclined to misdiagnosis and missed diagnosis. The patient, a 6-month-old male, was admitted to Dermatology Department of Children’s Hospital of Nanjing Medical University and Beijing Children’s Hospital successively, because of a erythema on the neck for 6 months and a mass in the neck for 3 months. Abdominal ultrasonography and CT indicated the possibility of hepatic hemangioma, but further examination of alpha fetoprote and other indicators suggested hepatic malignant tumor. Therefore, surgery was performed to remove the liver mass, and postoperative pathology revealed hepatoblastoma. Postoperative chemotherapy was combined, and follow-up was conducted six months after the end of chemotherapy, with no recurrence of the disease. This article summarized the diagnosis and treatment process of this case and combined with literature review to provide experience for clinicians in the diagnosis and treatment of relevant cases.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

JMJD1C (Jumonji Domain Containing 1C), a member of the lysine demethylase 3 (KDM3) family, is universally required for the survival of several types of acute myeloid leukemia (AML) cells with different genetic mutations, representing a therapeutic opportunity with broad application. Yet how JMJD1C regulates the leukemic programs of various AML cells is largely unexplored. Here we show that JMJD1C interacts with the master hematopoietic transcription factor RUNX1, which thereby recruits JMJD1C to the genome to facilitate a RUNX1-driven transcriptional program that supports leukemic cell survival. The underlying mechanism hinges on the long N-terminal disordered region of JMJD1C, which harbors two inseparable abilities: condensate formation and direct interaction with RUNX1. This dual capability of JMJD1C may influence enhancer-promoter contacts crucial for the expression of key leukemic genes regulated by RUNX1. Our findings demonstrate a previously unappreciated role for the non-catalytic function of JMJD1C in transcriptional regulation, underlying a mechanism shared by different types of leukemias.
