Hepatocellular carcinoma (HCC) with biliary duct tumor thrombus (BDTT) is currently not common in clinical practice and is easily misdiagnosed, and previously, it was often considered an advanced stage of the disease with a poor prognosis, making its treatment challenging. However, in-depth studies in recent years have gradually deepened our understanding of this disease, leading to significant changes in diagnostic and treatment concepts. Currently, comprehensive treatment, mainly surgery, is used for treatment, but there is still controversy over the selection of clinical treatment strategies. This article provides a detailed discussion on surgical methods and prognosis, in order to provide a reference for clinical treatment options.

BACKGROUND:Differentially expressed RNA-binding proteins in the intervertebral disc plays a key role in intervertebral disc degeneration,and decreased levels of the RNA-binding protein KRT18 are associated with degenerative disc disease,but its specific role in the nucleus pulposus cells has not yet been fully determined. OBJECTIVE:To investigate the interaction of KRT18 with mRNA and long non-coding RNA on nucleus pulposus cells of the intervertebral disc and its mechanism. METHODS:Normal and degenerated nucleus pulposus cells were obtained from nucleus pulposus samples of patients undergoing interbody fusion for lumbar fracture or intervertebral disc degeneration.iRIP-seq,functional enrichment analysis,and DNA microarray analysis were performed to identify the mRNA and long non-coding RNA binding with KRT18.Subsequently,KRT18 was knocked down in nucleus pulposus cells based on the analysis results,and the expression levels of related genes were detected at the protein and RNA levels through protein immunoblotting and qRT-PCR,respectively. RESULTS AND CONCLUSION:Through iRIP-seq analysis,we identified abundant KRT18 binding sites within the GUAAUC and AGCCUC sequences,indicating that KRT18 may be involved in regulating RNA transcription,translation,stability or play a role in cell signaling pathways.It can stably bind to mature mRNA,among which highly expressed genes include CRLF1,IGFBP4,etc.At the same time,the peak genes of long non-coding RNA binding with it include SNHG25,SNHG12,NEAT1,USP32,EIF4A2 and CDH4.Most of these genes are involved in various biological processes such as apoptosis and inflammation,and can mediate related pathways of extracellular matrix metabolism.KRT18 can regulate their stability,transport,translation,splicing and other functions,thus affecting gene expression and cell function.We further verified through experiments the knockdown of KRT18 in nucleus pulposus cells,and found that the level of extracellular matrix metabolism was inhibited and unbalanced,resulting in intervertebral disc degeneration in vitro.This study investigated the regulatory mechanism of KRT18 from the perspective of its binding with mRNA and long non-coding RNA for the first time,and speculated the potential function of KRT18 in the pathogenesis of intervertebral disc degeneration,laying a foundation for future research on the key functions of KRT18.

Background The increasing demand for emergency services coupled with the special working environment has exacerbated occupational stress and work-related rumination among emergency medical dispatchers, which is noteworthy for its impact on dispatchers' sleep quality. Objective To explore the relationship among occupational stress, work-related rumination, and sleep quality of emergency medical dispatchers, so as to provide reference for improving sleep quality and maintaining physical and mental health of this occupational group. Methods A total of 386 emergency medical dispatchers from 16 provinces and municipalities including Beijing, Shanghai, Tianjin, Inner Mongolia, Zhejiang, Shanxi, Jiangxi, Anhui, Hubei, Hebei, Henan, Sichuan, Guizhou, Yunnan, Fujian, and Hainan of China were investigated with the Chinese version of Effort-Reward Imbalance Questionnaire, Work-Related Rumination Questionnaire, and Insomnia Severity Index. Spearman correlation was used to analyze the association among occupational stress, work-related rumination, and sleep quality. A structural equation model was constructed, with occupational stress as independent variable, the two dimensions of work-related rumination as mediating variables, and sleep quality as dependent variable, respectively. Bootstrap testing was then used to verify potential mediating effect of work-related rumination on the relationship between occupational stress and sleep quality among the emergency medical dispatchers. Results Among the enrolled emergency medical dispatchers, the effort-reward imbalance (ERI) index was 1.03, the score of affective rumination was 15.35±5.26, the score of problem-solving rumination was 17.64±4.63, and the total score of sleep quality was 21.10±6.53. Their ERI index was positively correlated with affective rumination scores (r=0.636, P<0.01), but not with problem-solving rumination scores (P>0.05). Their ERI index, affective rumination scores, and problem-solving rumination scores were positively correlated with sleep quality scores (P<0.05). The direct effect size of occupational stress on sleep quality was 0.627, the indirect effect size of affective rumination was 0.124, and the mediating effect of affective rumination accounted for 16.4% of the total effect (0.755), while the problem-solving rumination had no mediating effect on the relationship between occupational stress and sleep quality. Conclusion Occupational stress and affective rumination in emergency medical dispatchers can predict their sleep quality. Occupational stress can directly affect sleep quality, and indirectly affect it through affective rumination. Managers should pay attention to and evaluate the affective rumination level of emergency medical dispatchers, so as to take corresponding intervention measures to reduce their occupational stress and improve their sleep quality.

Allergic rhinitis (AR) is one of the most common chronic non-infectious inflammatory diseases in children. Traditional Chinese medicine (TCM) employs a comprehensive therapeutic system integrating treatment by stages and syndrome differentiation and treatment, demonstrating significant advantages in the management of pediatric AR. This article systematically reviews the clinical treatment methods and underlying mechanisms of TCM for pediatric AR in recent years. It is found that internal therapies (such as herbal formulas or Chinese patent medicines like Xiaoqinglong decoction, Yiqi tuomin decoction), external therapies (including intradermal needles, acupoint application, tuina, and herbal nasal therapy), as well as combined internal and external approaches (oral herbs combined with acupoint application), have demonstrated significant effects in alleviating clinical symptoms, improving immune indicators, and reducing recurrence rates in children with AR. The underlying mechanisms are primarily associated with the regulation of signaling pathways such as Toll-like receptor/nuclear factor-kappa B and mitogen-activated protein kinase, thereby modulating immune balance, suppressing inflammatory responses, inhibiting pyroptosis, reducing mucus secretion, and promoting nasal mucosal repair.

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.

The complex pathophysiological mechanisms between diabetes mellitus and cardiovascular diseases have not yet been fully elucidated, becoming one of the challenges in clinical care. Glucagon-like peptide-1 receptor agonist (GLP1-RA) and sodium glucose cotransporter-2 inhibitors (SGLT2) are clinically used to reduce the cardiovascular risk of patients with diabetes mellitus. Traditional Chinese medicine has diverse biological activities and unique advantages in the treatment of chronic complex diseases due to its multi-component and multi-target effects. Based on recent reports, this paper reviewed the common risk factors of diabetes mellitus and cardiovascular diseases (e.g., hyperglycemia, insulin resistance, and inflammation), related targets such as apolipoprotein C-Ⅲ (APOC3), S100 calcium-binding protein A8/A9 (S100A8/A9), growth/differentiation factor-15 (GDF-15), and NACHT, LRR, and PYD domains-containing protein 3 (NLRP3), advanced glycation end products, insulin resistance, endothelial dysfunction, endoplasmic reticulum stress, mitochondrial dysfunction, and intestinal flora disorder. In addition, this paper summarized the research progress in the treatment of cardiovascular diseases in diabetes mellitus with the active ingredients (e.g., baicalein, puerarin, curcumin, notoginsenoside, and tanshinone ⅡA), single herbal medicines (e.g., Astragali Radix, Ginseng Radix et Rhizoma, Sophorae Flavescentis Radix, Cinnamomi Cortex, and Corni Fructus), and compound formulas (e.g., Buzang Tongluo Fang, Yiqi Yangyin Huoxue Fang, Shenqi Fang, Huangqisan, Danggui Buxue Tang, and Liuwei Dihuang Wan) of traditional Chinese medicine. Traditional Chinese medicine mainly treats cardiovascular diseases in diabetes mellitus by reducing inflammation and oxidative stress, ameliorating dyslipidemia and insulin resistance, protecting islet β cell function, repairing endothelial damage, inhibiting smooth muscle cell proliferation, foam cell formation, macrophage polarization, and cardiac hypertrophy and fibrosis, and regulating intestinal flora disorder. These processes involve insulin receptor substrate/ phosphatidylinositol 3-kinase/protein kinase B (IRS/PI3K/Akt), peroxisome proliferator-activated receptor α/γ (PPAR α/γ), nuclear factor-kappa B (NF-κB), adenosine 5′-monophosphate (AMP)-activated protein kinase (AMPK), hypoxia-inducible factor-1-BCH domain-containing protein (HIF-1-BNIP), vascular endothelial growth factor/hypoxia-inducible factor-1α (VEGF/HIF-1α) and other signaling pathways. This review is expected to provide a theoretical basis and reference for the treatment of cardiovascular diseases in diabetes mellitus with traditional Chinese medicine.
