Diabetic nephropathy （DN） is one of the most common and severe microvascular complications of diabetes， with a complex pathogenesis involving immune inflammatory responses， oxidative stress， apoptosis， glomerulosclerosis， renal interstitial fibrosis， and other pathological processes. In recent years， numerous animal or cell model experiments have revealed that the transforming growth factor-β （TGF-β）/mothers against decapentaplegic homolog （Smad）， phosphoinositide 3-kinase （PI3K）/ protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， mitogen-activated protein kinase （MAPK）， AMP-activated protein kinase （AMPK）， nuclear factor-κB （NF-κB）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2）， secretory glycoprotein （Wnt）/β-catenin， and other classical signaling pathways play important roles in the occurrence and development of DN. Traditional Chinese medicines， as natural drugs， possess characteristics such as multiple components， multiple targets， and few adverse reactions， demonstrating unique advantages in regulating the aforementioned signaling pathways and improving renal pathological changes. This review summarized recent research progress on the intervention of DN through the regulation of the aforementioned signaling pathways by single compounds and formulas of traditional Chinese medicine， focusing on their mechanisms of action in regulating immune inflammatory responses， inhibiting renal fibrosis， oxidative stress， improving metabolic disorders， and other aspects. The aim is to provide theoretical references for a deeper understanding of the modern pharmacological basis and clinical application of traditional Chinese medicine in the treatment of DN.

OBJECTIVE To systematically evaluate medication risk prediction models for hospitalized adult patients and provide references for their development and clinical application. METHODS Databases including PubMed， Embase， Web of Science， CNKI， Wanfang data， VIP and CBM were searched for studies on medication risk prediction models from their inception to May 2024. After screening the literature， extracting data， and evaluating the quality of the literature， descriptive analysis was performed on the results of the included studies. RESULTS A total of 13 studies were included， involving 12 models. Nine studies used Logistic regression algorithm for modeling， and the number of included predictive factors ranged from 3 to 11； the area under the receiver operating characteristic curve ranged from 0.65 to 0.865. The literature quality evaluation results showed that 10 studies had high risk of bias； 10 studies had high applicability risk. A total of 31 predictive factors were extracted， including 15 items of basic patient information， 3 test indicators， and 5 items of medication information， and 8 others. CONCLUSIONS The existing medication risk prediction models for hospitalized adult inpatients are mainly Logistic regression algorithm， with predictive factors mainly focusing on basic indicators such as demographics. The overall prediction performance of the models needs to be improved， and the overall risk of bias is relatively high.

Osteosarcoma(OS)is a common primary malignant bone tumor with high mortality,disability,metastasis,and recurrence rates and a complex pathogenesis,Resulting in serious effects on patient quality of life and huge economic burdens on families and society.Traditional Chinese medicine(TCM)has"multi-target,multi-component and multi-pathway"characteristics.Recent studies using animal and cell models demonstrated that the mechanism of OS progression was related to Notch,mitogen-activated protein kinase,Wnt/β-catenin,phosphatidylinositol 3-kinase/AKT,Hedgehog and nuclear factor-κB,transforming growth factor-β/Smad and signal transducer and activator of transcription pathways.TCM can exert anti-tumor effects by influencing biological processes such as cell proliferation,migration,invasion,apoptosis,and autophagy via interfering with the above signaling pathways.This review considers the roles of these signaling pathways in OS and summarizes the current research status of TCM interventions in the prevention and treatment of OS,with the aim of providing a reference for future studies of TCM treatments of OS and to provide new ideas for its clinical treatment.

Severe open tibiofibular fractures account for approximately 28.1% of all open fractures. Among them, Gustilo-Anderson type IIIB/C fractures present significant clinical challenges due to associated bone and soft tissue defects, high infection rates, and risk of amputation. Inadequate preoperative assessment may lead to suboptimal emergency surgical planning or intraoperative complications. Historically, external fixation was often preferred, but this approach has been associated with limitations such as restricted joint mobility, delayed bone union, joint stiffness, and disuse osteoporosis, resulting in poor functional recovery. With advancements of debridement techniques, standardization of antibiotic use, and popularization of early soft tissue coverage, early internal fixation has gained broader acceptance. Nevertheless, controversies persist regarding the choice of fixation method, timing of definitive fixation, use of reamed versus unreamed intramedullary nailing, and necessity of fibular fixation. To standardize the diagnosis and early management of severe open tibiofibular fractures, reduce complication rates, and improve functional recovery, the Society of Microsurgery of the Chinese Medical Association organized a panel of domestic experts to develop the Evidence-based guideline for the diagnosis and early fixation of severe open tibiofibular fractures ( version 2025), using evidence-based methodology. The guidelines provided 12 recommendations covering diagnostic and early fixation strategies of severe open tibiofibular fractures, aiming to provide clinicians with scientifically grounded and standardized guidance.

Ankylosing spondylitis is a chronic immunoinflammatory disease that mainly affects the spine and the sacroiliac joint,the mechanism of which is closely related to signaling pathways,such as osteoprotegerin(OPG)/receptor activator of nuclear factor-κB(RANK)/RANK ligand,mitogen-activated protein kinase(MAPK),Wnt/β-catenin(β-catenin),phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR).Traditional Chinese medicine has the characteristics of multiple components and targets,and is widely used for the treatment of autoimmune diseases due to its low toxicity,strong specificity,and high efficacy.This review found that monomers and compounds of traditional Chinese medicine can exert anti ankylosing spondylitis effects by intervening in the aforementioned signaling pathways,regulating immune inflammatory responses,and inhibiting biological processes such as bone destruction,ectopic osteogenic differentiation,cell apoptosis,and autophagy.

Objective To analyze the magnetic resonance images (MRI) of patients with spinal epidural lipomatosis (SEL) in high-altitude areas and to determine the optimal cut-off value for diagnosis with epidural fat thickness. Methods This retrospective study included patients who underwent lumbosacral MRI examination for lumbosacral pain in Ping’an District Hospital of Traditional Chinese Medicine, Haidong City, China from January 1, 2021 to December 31, 2022. The epidural fat thickness in vertebral segments T12/L1 to L5/S1 was compared between the SEL group and the non-SEL group. The diagnostic efficacy with different cut-off values at each vertebral segment was evaluated. Between-group comparisons were performed using the t-test, Mann-Whitney U test, chi-square test, or modified chi-square test. The area under the receiver operating characteristic (AUC) was used to evaluate the diagnostic efficiency. The DeLong test was used to compare AUC between the two groups. Results A total of 370 patients were included (60 in the SEL group and 310 in the non-SEL group). There were no significant differences in age, sex, height, body weight, and body mass index between the two groups (all P > 0.05). At different vertebral segments, the epidural fat thickness was significantly higher in the SEL group than in the non-SEL group (all P < 0.05). The cut-off values for SEL diagnosis with epidural fat thickness in segments T12/L1 to L5/S1 were 2.23, 4.25, 4.85, 5.57, 7.21, and 8 mm, respectively. The AUC of MRI SEL diagnosis with epidural fat thickness in segment L5/S1 was the highest (0.945, 95% confidence interval [CI]: 0.916-0.966, P < 0.001). SEL diagnosis with epidural fat thickness > 8 mm in segment L5/S1 was the most accurate, with an AUC of 0.931 (95% CI: 0.901-0.955, P < 0.001), a sensitivity of 95.0%, and a specificity of 91.3%; this AUC was significantly higher than those of diagnosis with other cut-off values (all P < 0.05). Conclusion SEL patients have significantly increased epidural fat in the spinal canal. Epidural fat thickness > 8 mm in segment L5/S1 can be used for diagnosis of SEL with improved efficiency and accuracy.

Integrating evidence from animal experiments is a critical component of biomedical research, providing essential prior information for in-depth investigations of disease mechanisms and new drug development. Animal models have played an irreplaceable role in simulating human diseases. However, the integration of evidence from animal experiments has faced numerous challenges, including insufficient emphasis, significant heterogeneity in study designs, high publication bias, and discrepancies with clinical research practices. This paper first identifies existing issues in the original research evidence from animal experiments, such as the selection and applicability of animal models, considerations in the design of experimental studies, and factors influencing the translation of animal experimental evidence. It then discusses various methods for integrating this evidence, including systematic review and meta-analysis, overview of systematic review/umbrella review, scoping review, and evidence mapping, while highlighting recent advancements in their application. Finally, the paper addresses the main challenges currently encountered in the integration of evidence from animal experiments and proposes targeted improvement strategies aimed at enhancing the efficiency of translating research outcomes into clinical practice and promoting the advancement of evidence-based medicine. By continuously optimizing original experimental research protocols and evidence integration practices, this work aims to establish a more efficient and scientific environment for the synthesis of evidence from animal experiments, ultimately contributing to clinical trials and human health.

OBJECTIVE To investigate the effect of andrographolide （Andro） on the neuronal apoptosis in ischemic stroke （IS） rats by regulating the neuregulin-1 （Nrg-1）/epithelial growth factor receptor 4 （ErbB4） signaling pathway. METHODS The IS rat model was established using the suture method. Sixty successfully modeled rats were randomly divided into model group （physiological saline）， Andro low-dose group （Andro-L group， 50 mg/kg）， Andro high-dose group （Andro-H group， 100 mg/kg）， and Andro-H+Dacomitinib group （100 mg/kg of Andro+7.5 mg/kg of Nrg-1/ErbB4 signaling pathway inhibitor Dacomitinib）， with 15 rats in each group. Another 15 rats were chosen as the sham group （physiological saline）. The rats were intragastrically administered medication/physiological saline once a day for 7 consecutive days. After medication， the neurological function of the rats was assessed； the levels of lactate dehydrogenase （LDH）， tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， IL-10， and nerve growth factor （NGF） in the rat serum were detected； the infarct area of the rat brain was measured， and the pathological changes in the hippocampal tissue of the rats were observed. Moreover， the apoptosis rate of hippocampal neurons and the levels of malondialdehyde （MDA）， superoxide dismutase （SOD）， catalase （CAT）， matrix metalloproteinase-9 （MMP-9）， cleaved-caspase- 3， Nrg-1 protein expressions and phosphorylated ErbB4 （p-ErbB4）/ErbB4 ratio in the hippocampal tissue were detected. RESULTS Compared with the model group， the Zea-Longa score， the escape latency， the serum LDH， TNF-α， IL-1β levels， the percentage of cerebral infarction area， the hippocampal neuron apoptosis rate， the MDA level and MMP-9， cleaved-caspase-3 protein expression levels in the hippocampal tissue in the Andro-L and Andro-H groups were significantly reduced/shortened （P＜0.05）. The dwelling time， the number of platform crossings， the serum IL-10， NGF levels， the CAT， SOD levels， the Nrg-1 protein expression level and p-ErbB4/ErbB4 ratio in the hippocampal tissue were significantly extended/increased （P＜0.05）； the degree of hippocampal neural tissue damage was significantly E-mail：lrxxl3@163.com reduced. Dacomitinib could significantly weaken the improvement effect of high-dose Andro on neuronal injury in IS rats （P＜0.05）. CONCLUSIONS Andro can reduce the inflammatory response， oxidative stress， and hippocampal tissue damage in IS rats， and promote neurological function. Its mechanism of action may be related to the activation of Nrg-1/ErbB4 signaling pathway.
