Acute-on-chronic liver failure （ACLF） is a syndrome of multiple organ failure on the basis of underlying chronic liver disease and has an extremely high short-term mortality rate， while there is still a lack of unified diagnostic criteria around the world. Radiology plays an important role in the evaluation and prognostic prediction of ACLF， constituting a multi-dimensional assessment system covering morphology， function， and hemodynamics. Computed tomography can be used for the measurement of liver volume and the diagnosis of sarcopenia by providing key morphological and nutritional parameters. Magnetic resonance imaging （MRI）， especially gadobenate dimeglumine-enhanced MRI， enables quantitative assessment of liver function and has critical significance for predicting short-term survival rate. Ultrasonography and elastography techniques facilitate the early warning of ACLF onset and the dynamic monitoring of its progression through noninvasive measurement of liver stiffness and hemodynamic parameters. This article systematically reviews the pivotal role of these three imaging modalities in the diagnosis and monitoring of ACLF， and integrating the strengths of multiple imaging techniques with clinical indicators to construct diagnostic and prognostic models may become a key future direction for achieving early intervention and improving clinical outcomes in ACLF.

To target the pivotal BCR/ABL oncoprotein in chronic myeloid leukemia (CML) cells, tyrosine kinase inhibitors (TKIs) are utilized as landmark achievements in CML therapy. However, TKI resistance and intolerance remain principal obstacles in the treatment of CML patients. In recent years, drug repositioning provided alternative and promising perspectives apart from the classical cancer therapies, and promoted anthelmintic mebendazole (MBZ) as an effective anti-cancer drug in various cancers. Here, we investigated the role of MBZ in CML treatment including imatinib-resistant CML cells. Our results proved that MBZ inhibited the proliferation and induced apoptosis in CML cells. We found that MBZ effectively suppressed BCR/ABL kinase activity and MEK/ERK signaling pathway by reducing p-BCR/ABL and p-ERK levels with ABL1 targeting ability. Meanwhile, MBZ directly targeted the colchicine-binding site of β-tubulin protein, hampered microtubule polymerization and induced mitosis arrest and mitotic catastrophe. In addition, MBZ increased DNA damage levels and hampered the accumulation of ataxia-telangiectasia mutated and DNA-dependent protein kinase into the nucleus. This work discovered that anthelmintic MBZ exerts remarkable anticancer effects in both imatinib-sensitive and imatinib-resistant CML cells in vitro and revealed mechanisms underlying. From the perspective of drug repositioning and multi‐target therapeutic strategy, this study provides a promising option for CML treatment, especially in TKI-resistant or intolerant individuals.

Objective To investigate and analyze the association between serum microRNA-141-3p(miR-141-3p)and miR-223-3p levels and neonatal necrotizing enterocolitis.Methods Eighty neonates with necrotizing enterocolitis admitted to our hospital between January 2019 and January 2022 were enrolled as subjects.According to the disease stage,they were divided into the stage Ⅱ group(n=43)and the stage Ⅲ group(n=37).Additionally,80 healthy newborns born during the same period were recruited as the control group.General clinical data were collected and analyzed systematically.The expression levels of miR-141-3p and miR-223-3p were detected using quantitative real-time PCR(qRT-PCR).Spearman's correlation analysis was performed to evaluate the relationship between miR-141-3p,miR-223-3p,and the severity of the disease.Multivariate logistic regression analysis was conducted to assess the impact of miR-141-3p and miR-223-3p on the severity of pediatric illness.Furthermore,a Receiver Operating Characteristic(ROC)curve was plotted to determine the diagnostic value of miR-141-3p and miR-223-3p in predicting the severity of the patient's condition.Results Compared with the control group,the rela-tive expression levels of miR-141-3p and miR-223-3p in the diseased group were significantly decreased(P<0.05).Similarly,compared with the stage Ⅱ group,the relative expression levels of miR-141-3p and miR-223-3p in the stage Ⅲ group were also markedly reduced(P<0.05).Furthermore,miR-141-3p and miR-223-3p exhibited a nega-tive correlation with disease severity(r=-0.489,-0.496,P<0.05).Increased relative expression of miR-141-3p and miR-223-3p was identified as a protective factor influencing disease severity in children(P<0.05).The AUC values for diagnosing the severity of necrotizing enterocolitis using miR-141-3p,miR-223-3p,and their combination were 0.806,0.783,and 0.885,respectively.Combined diagnosis demonstrated significantly better performance than miR-141-3p alone(Z=2.050,P=0.040)or miR-223-3p alone(Z=2.184,P=0.029).Conclusion In neonates with necrotizing enterocolitis,the relative expression levels of serum miR-141-3p and miR-223-3p are significantly decreased,which are closely associated with disease progression and provide potential auxiliary diagnostic value for assessing disease severity.

Objective:To evaluate the clinical efficacy and the mid- and long-term follow-up outcomes of transanal anaplasty for treating rectovestibular fistula.Methods:The clinical data of 68 female infants diagnosed with rectovestibular fistula undergoing transanal anoplasty at the Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from Oct 2014 to Dec 2023 was collected. Postoperative complications, perineal and anal appearances, and defecation function of postoperative children aged 3 years or older were recorded.Results:After surgery 68 children followed-up for 6 months of recent with short-term complications in 6 cases, including 3 cases of incision infection, 2 cases of rectal mucosal prolapse, and 1 case of anal stenosis. Rintala score was (18.65±1.99). Twenty-five children underwent anorectal manometry, no significant differences were observed in the maximal systolic pressure of the anal canal( t=-0.596, P=0.563) and the maximum systolic time( t=-0.183, P=0.854). The resting pressure( t=-3.050, P=0.005), functional length( t=2.696, P=0.012), and positive rate of rectal anal inhibitory reflex( χ2=6.382, P=0.012) of the anal canal were significantly lower than those of the normal group( P<0.05). Conclusions:Transanal anaplasty for the treatment of rectovestibular fistula in girls has a low incidence of complications. It results in a normal perineal body appearance, good anal bowel control, and high quality of life.

Objective To explore the research hotspots and development trends in the field of cancer treatment in the past decade. Methods The CNKI and Web of Science Core Collection databases were searched for Chinese and English articles related to cancer treatment published over the last 10 years. Bibliometric research methods were employed, including keyword cluster analysis of published literature. Results A total of 45 455 Chinese articles and 866 958 English articles were retrieved. Combining the visualization analysis results and the current research dilemma of tumor treatment revealed that the current research hotspots of tumor treatment domestically and internationally can primarily focus on four key areas. In the realm of targeted therapy, efforts are directed towards the discovery of new drug targets, overcoming resistance to targeted therapy, and the development of monoclonal antibodies and antibody–drug conjugates. In the field of immunotherapy, the emphasis lies in enhancing the response rate to immune checkpoint inhibitors, determining the mechanisms behind resistance to immunotherapy, and improving the safety of treatment. The research in traditional Chinese medicine (TCM) covers evidence-based evaluation studies on TCM treatment, the identification of populations that can gain the most benefit from TCM, and strategies for improving the quality of life. In the area of novel drug development, cutting-edge technologies, such as organoid-based screening for anticancer drugs, synthetic biology, and artificial intelligence, are under investigation. Conclusion New targeted drugs, immune efficacy improvement, multidisciplinary integration, nano-delivery, and TCM innovation are the key research directions in the field of tumor therapy in the future.

Objective:This study aimed to investigate the regulatory role and mechanism of myosin heavy chain 9 (MYH9) in the invasion of Zika virus (ZIKV) into human glioma cells (U251).Methods:Utilizing CRISPR/Cas9 technology, MYH9-knockout U251 cells (U251-MYH9 KD) were constructed. Following ZIKV infection, the protein expression levels, RNA load, and viral titer of ZIKV were detected through western blot (WB), Real-time fluorescence quantitative polymerase chain reaction (qPCR), and plaque formation assays, respectively. The infection efficiency of ZIKV in U251 cells treated with the MYH9 inhibitor blebbistatin was assessed. The binding and internalization efficiency of ZIKV were measured in U251-MYH9 KD cells. The interaction between MYH9 and the ZIKV envelope protein (E) was studied using co-immunoprecipitation (Co-IP). The effects of soluble MYH9 recombinant protein and anti-human MYH9 antibodies on ZIKV infection were evaluated by qPCR and plaque formation assays. Results:It was found that knockout or inhibition of MYH9 significantly suppressed ZIKV infection in U251 cells. MYH9 knockout notably inhibited the binding and internalization of ZIKV in U251 cells. MYH9 interacted with the ZIKV E protein, and both MYH9 recombinant protein and anti-human MYH9 antibodies, by blocking the binding of ZIKV E protein to cell surface MYH9, inhibited ZIKV infection in U251 cells in a dose-dependent manner.Conclusions:MYH9 facilitates ZIKV invasion into U251 cells through interaction with the ZIKV E protein.

ObjectiveTo investigate the potential mechanism of Liangxue Tuizi Formula （凉血退紫方， LXTZF） in treating Henoch-Schönlein Purpura （HSP） by examining its regulatory effect on neutrophil extracellular trap （NETs） dysregulation via the rapidly accelerated fibrosarcoma kinase （RAF）/mitogen-activated protein kinase （MEK）/extracellular signal-regulated kinase （ERK） signaling pathway. MethodsSeventy Wistar rats were randomly allocated into a blank control group （n=14） and a modeling group （n=56）. Rats in the modelling group underwent an eight-week modelling period to establish HSP rat models with blood-heat syndrome via modified ovalbumin （OVA） induction method combined with oral administration of heat-property Chinese herbal medicine. Fifty successfully modeled rats were subsequently randomly divided into five groups （n=10 per group）， model group， compound glycyrrhizin group， LXTZF group， RAF inhibitor group， and LXTZF + RAF agonist group. Additionally， 10 rats were selected from the original blank control group for the final experiment. From the 11th week of modelling， rats in the blank control group and the model group received 1 ml/（100 g·d） ultrapure water via oral administration， in addition to 0.5 ml/（kg·d） 0.9% sodium chloride solution via intraperitoneal injection. The LXTZF group and the compound glycyrrhizin group received 7.5 g/（kg·d） LXTZF granule suspension via gavage， 13.5 mg/（kg·d） compound glycyrrhizin suspension via gavage， respectively. The RAF inhibitor group received 1 mg/（kg·d） GW5074 suspension via intraperitoneal injection and ultrapure water via oral administration； the LXTZF + RAF agonist group received 7.5 g/（kg·d） LXTZF granule suspension via gavage and 1 mg/（kg·d） paclitaxel suspension via intraperitoneal injection. All administrations were performed once daily for 4 weeks. After intervention， skin tissue histopathology was examined by hematoxylin and eosin （H&E） staining， immunoglobulin A （IgA） deposition was assessed via immunofluorescence， serum levels of neutrophil elastase （NE）， tumor necrosis factor-α （TNF-α）， and vascular cell adhesion molecule-1 （VCAM-1） were measured using enzyme-linked immunosorbent assay （ELISA）， serum myeloperoxidase （MPO） level was determined by a colorimetric assay； the mRNA expression levels of RAF， MEK， and ERK in skin tissue were detected by real-time quantitative polymerase chain reaction （RT-qPCR）； and the protein expression of RAF， MEK， ERK， as well as phosphorylated MEK （p-MEK） and phosphorylated ERK （p-ERK）， were analyzed by Western Blot. ResultsSkin tissue in the blank control group rats remained normal， whereas the model group exhibited neutrophil infiltration and haemorrhage with red blood cell rupture. In all drug intervention groups， neutrophil infiltration and haemorrhagic exudation reduced markedly， with LXTZF group demonstrating the most pronounced improvement. Compared with the blank control group， rats in the model group exhibited enhanced IgA fluorescence intensity in skin tissue， elevated serum levels of NE， MPO， TNF-α and VCAM-1， increased mRNA expression of RAF， MEK， ERK1 and ERK2， as well as heightened RAF protein levels and p-MEK/MEK and p-ERK/ERK ratios （P＜0.05）. Compared with the model group， the drug intervention groups exhibited reduced IgA fluorescence intensity in skin tissue， along with decreased serum levels of NE， MPO， TNF-α， and VCAM-1 （P＜0.05）. In LXTZF group and RAF inhibition groups， reduced mRNA expression of RAF， MEK， ERK1， and ERK2 was observed in rat skin tissue， alongside decreased RAF protein levels and reduced p-MEK/MEK and p-ERK/ERK ratios （P＜0.05）. Compared with LXTZF + RAF agonist group， the compound glycyrrhizin group， LXTZF group， and RAF inhibitior group exhibited reduced IgA fluorescence intensity in skin tissue， decreased serum NE， MPO， TNF-α， and VCAM-1 levels， and decreased MEK mRNA expression and p-MEK/MEK ratio （P＜0.05）. ConclusionThe potential mechanism by which LXTZF treats Henoch-Schönlein purpura with blood heat syndrome may involve blocking the RAF/MEK/ERK signaling pathway in skin tissue， and suppressing excessive formation of NETs， thereby reducing IgA deposition in dermal microvessels and attenuating systemic inflammatory responses.
