BACKGROUND:
Chronic kidney disease (CKD) is associated with common pathophysiological processes, such as inflammation and fibrosis, in both the heart and the kidney. However, the underlying molecular mechanisms that drive these processes are not yet fully understood. Therefore, this study focused on the molecular mechanism of heart and kidney injury in CKD.
METHODS:
We generated an microRNA (miR)-26a knockout (KO) mouse model to investigate the role of miR-26a in angiotensin (Ang)-II-induced cardiac and renal injury. We performed Ang-II modeling in wild type (WT) mice and miR-26a KO mice, with six mice in each group. In addition, Ang-II-treated AC16 cells and HK2 cells were used as in vitro models of cardiac and renal injury in the context of CKD. Histological staining, immunohistochemistry, quantitative real-time polymerase chain reaction (PCR), and Western blotting were applied to study the regulation of miR-26a on Ang-II-induced cardiac and renal injury. Immunofluorescence reporter assays were used to detect downstream genes of miR-26a, and immunoprecipitation was employed to identify the interacting protein of LIM and senescent cell antigen-like domain 1 (LIMS1). We also used an adeno-associated virus (AAV) to supplement LIMS1 and explored the specific regulatory mechanism of miR-26a on Ang-II-induced cardiac and renal injury. Dunnett's multiple comparison and t -test were used to analyze the data.
RESULTS:
Compared with the control mice, miR-26a expression was significantly downregulated in both the kidney and the heart after Ang-II infusion. Our study identified LIMS1 as a novel target gene of miR-26a in both heart and kidney tissues. Downregulation of miR-26a activated the LIMS1/integrin-linked kinase (ILK) signaling pathway in the heart and kidney, which represents a common molecular mechanism underlying inflammation and fibrosis in heart and kidney tissues during CKD. Furthermore, knockout of miR-26a worsened inflammation and fibrosis in the heart and kidney by inhibiting the LIMS1/ILK signaling pathway; on the contrary, supplementation with exogenous miR-26a reversed all these changes.
CONCLUSIONS
Our findings suggest that miR-26a could be a promising therapeutic target for the treatment of cardiorenal injury in CKD. This is attributed to its ability to regulate the LIMS1/ILK signaling pathway, which represents a common molecular mechanism in both heart and kidney tissues.

OBJECTIVES:
We propose a YOLOv11-TDSP model for improving the accuracy of dental abnormality detection on panoramic oral X-ray images.
METHODS:
The SHSA single-head attention mechanism was integrated with C2PSA in the backbone layer to construct a new C2PSA_SHSA attention mechanism. The computational redundancy was reduced by applying single-head attention to some input channels to enhance the efficiency and detection accuracy of the model. A small object detection layer was then introduced into the head layer to correct the easily missed and false detections of small objects. Two rounds of structured pruning were implemented to reduce the number of model parameters, avoid overfitting, and improve the average precision. Before training, data augmentation techniques such as brightness enhancement and gamma contrast adjustment were employed to enhance the generalization ability of the model.
RESULTS:
The experiment results showed that the optimized YOLOv11-TDSP model achieved an accuracy of 94.5%, a recall rate of 92.3%, and an average precision of 95.8% for detecting dental abnormalities. Compared with the baseline model YOLOv11n, these metrics were improved by 6.9%, 7.4%, and 5.6%, respectively. The number of parameters and computational cost of the YOLOv11-TDSP model were only 12% and 13% of those of the high-precision YOLOv11x model, respectively.
CONCLUSIONS
The lightweight YOLOv11-TDSP model is capable of highly accurate identification of various dental diseases on panoramic oral X-ray images.

The nod-like receptor family pyrin domain containing 3 (NLRP3) inflammasome plays a crucial role in the prognosis of subarachnoid hemorrhage (SAH). WNK1 kinase negatively regulates NLRP3 in various inflammatory conditions, but its role in early brain injury (EBI) after SAH remains unclear. In this study, we used an in vivo SAH model in rats/mice and AAV-WNK1 intraventricular injection to investigate its neuroprotective mechanisms. WNK1 expression was significantly reduced in SAH patient blood and SAH model brain tissue, correlating negatively with microglial activation. AAV-WNK1 alleviated brain edema, neuronal necrosis, behavioral deficits, and inflammation by inhibiting NLRP3 inflammasome activation. In hemin-stimulated BV-2 cells, WNK1 overexpression reduced NLRP3 activation and inflammatory cytokines. Chloride counteracted WNK1's inhibitory effects, and WNK1 suppressed P2X7R-induced NLRP3 activation. Mechanistically, WNK1 functioned via the OXSR1/STK39 pathway. These findings highlight WNK1 as a key regulator of intracellular chloride balance and neuroinflammation, presenting a potential therapeutic target for SAH treatment.

Objective:To conduct a comprehensive review on the current research status of postpartum follow-up for patients with hypertensive disorders of pregnancy (HDP), and provide a basis and guidance for the management of postpartum follow-up for HDP patients.Methods:Guided by the methodological framework of the scoping review, the literatures on postpartum follow-up of HDP patients in Cochrane Library, PubMed, Web of Science, Embase, China Biomedical Literature Database, China National Knowledge Infrastructure, VIP and Wanfang databases were retrieved, and search for relevant literature by the snowballing method. The search time range is from the establishment of the database to February 1, 2025. The included literature was analyzed and summarized.Results:A total of 32 literatures were included, including 31 in English and 1 in Chinese. The participation rate of postpartum follow-up for HDP patients is generally low, and the disease has a significant impact on long-term health. In addition, there is considerable variation in the content, format and time of follow-up. The follow-up content includes the patient's physical health status, long-term health risks and the availability of medical resources, etc.Conclusions:There are still deficiencies in the current implementation of postpartum follow-up for HDP patients. Existing follow-up studies lack high-quality randomized controlled trials as evidence support, and the influencing factors are complex and diverse. In the future, it is necessary to strengthen cooperation among multiple disciplines, closely integrate clinical guidelines with practical needs, and systematically evaluate the effectiveness of follow-up in clinical practice to enhance the scientific and effectiveness of follow-up and provide better health management support for HDP patients.

Anterior cruciate ligament(ACL)injury is caused by strong violence,which can destabilize the knee joint,cause joint cartilage degeneration,meniscus injury,and in severe cases,develop osteoarthropathy.The gold standard for the treatment of ACLR injuries at this stage is arthroscopic anterior cruciate ligament recon-struction(ACLR).In clinical practice,the LARS(Ligament advanced reinforcement system)artificial ligament made of polyethylene terephthalate(PET)as the material has a good effect in the short and medium term,but the long-term biological healing between the graft and the host bone is poor,and the real"ligamentization"requirement of the postoperative graft cannot be met.Coating-modified modification of artificial ligaments can improve their hydrophilicity and biocompatibility,which in turn can promote the healing of graft-bone tunnels.Tendon bone healing is a bone-derived progressive process from indirect insertion to direct insertion,which takes a relatively long time and is closely related to the prognosis and early rehabilitation effect of patients.This article reviews the progress of superficial modification of artificial ligaments to promote ACLR tendon bone healing.
