Compared with traditional therapies for chronic liver disease （CLD）， Bifidobacterium has the characteristics of multi-target intervention， high biosafety， and good host compatibility and provides new strategies for intervention of CLD progression in terms of microecological regulation. Various studies have shown that Bifidobacterium regulates liver homeostasis and exerts a therapeutic effect on CLD by regulating intestinal flora， maintaining antioxidation， promoting energy consumption， alleviating inflammation， improving glycolipid metabolism， and exerting an antitumor effect. This article systematically reviews the studies on Bifidobacterium in the treatment of CLD in China and globally， explores their different mechanisms， and elaborates on the interaction between related signaling pathways （such as the nuclear factor erythroid 2-related factor 2 signaling pathway and the adenosine monophosphate-activated protein kinase signaling pathway） and the liver， in order to provide a basis for probiotic intervention in liver pathology， as well as new ideas for the comprehensive treatment of CLD.

Objective To explore the dominant views with positive results when performing echocardiography on common congenital heart disease (CHD) in children using the seven-step screening method for pediatric echocardiography. Methods The echocardiographic data of children with atrial septal defect, patent foramen ovale, ventricular septal defect, and patent ductus arteriosus were collected from September 2021 to February 2022. The disease type distribution, view distribution, and the dominant view distribution were analyzed. Dominant view referred to the view with a high ratio of positive result images per view to the total image in each disease. Results A total of 8 353 images of 1 633 children with common CHD were collected. There were 813 males and 820 females ageed 0-7 years, including 3 613 images in 701 patients with atrial septal defect, 1 178 images in 206 patients with patent foramen ovale, 2 857 images in 576 patients with ventricular septal defect, and 705 images in 150 patients with patent ductus arteriosus. The dominant views of atrial septal defect were subxiphoid 2-chamber view (92.96%), subxiphoid 4-chamber view (85.61%), parasternal 4-chamber view (62.07%), and parasternal short-axis view (38.50%). The dominant views of patent foramen ovale were subxiphoid 2-chamber view (82.69%) and subxiphoid 4-chamber view (65.41%). The dominant views of ventricular septal defect were parasternal 5-chamber view (79.73%), parasternal short-axis view (79.41%), parasternal 4-chamber view (58.18%), and parasternal long-axis view (51.11%). The dominant view of patent ductus arteriosus was parasternal short-axis view (98.80%). Conclusion The analysis of the lesion key areas of common CHD shows that there are 4 dominant views for atrial septal defect and ventricular septal defect, 2 for patent foramen ovale, and only 1 for patent ductus arteriosus. Clarifying the dominant views of common CHD is conducive to rapid and accurate diagnosis of diseases, clinical practice, teaching and scientific research.

OBJECTIVES: In recent years, the incidence and detection rate of pancreatic cystic lesions (PCLs) have increased significantly. Endoscopic ultrasound (EUS) plays an indispensable role in the diagnosis and differential diagnosis of PCLs. However, evidence comparing the diagnostic performance of EUS-guided fine-needle aspiration (EUS-FNA) and fine-needle biopsy (FNB) remains limited. This study aims to compare the diagnostic yield, adequacy of tissue acquisition, and safety between EUS-FNA and EUS-FNB in evaluating PCLs to inform clinical practice. METHODS: A retrospective review was conducted on patients with PCLs who underwent either EUS-FNA or EUS-FNB between January 2014 and August 2021. The diagnostic yield, tissue acquisition adequacy, and incidence of adverse events were compared between the 2 groups. RESULTS: A total of 90 patients with PCLs were included (52 in the FNA group and 38 in the FNB group). The diagnostic yield was similar between the FNA and FNB groups (94.2% vs 94.7%, P>0.05). The adequacy of tissue acquisition was 71.2% in the FNA group and 81.6% in the FNB group (P>0.05). No statistically significant difference was observed in the incidence of adverse events between the 2 groups (P>0.05). CONCLUSIONS Both EUS-FNA and EUS-FNB demonstrate equally high diagnostic yields and tissue adequacy in PCLs, with excellent safety profiles. Both methods are safe and effective diagnostic tools for evaluating PCLs.

Dysfunction of anti-tumor immune responses is crucial for cancer progression. Immune checkpoint blockade (ICB), which can potentiate T cell responses, is an effective strategy for the normalization of host anti-tumor immunity. In recent years, immune checkpoints, expressed on both tumor cells and immune cells, have been identified; some of them have exhibited potential druggability and have been approved by the US Food and Drug Administration (FDA) for clinical treatment. However, limited responses and immune-related adverse events (irAEs) cannot be ignored. This review outlines the development and applications of ICBs, potential strategies for overcoming resistance, and future directions for ICB-based cancer immunotherapy.

Coronavirus-related diseases pose a significant challenge to the global health system. Given the diversity of coronaviruses and the unpredictable nature of disease outbreaks, the traditional "one bug, one drug" paradigm struggles to address the growing number of emerging crises. Therefore, there is an urgent need for therapeutic agents with broad-spectrum anti-coronavirus activity. Here, we provide evidence that ATV006, an anti-SARS-CoV-2 nucleoside analog targeting RNA-dependent RNA polymerase (RdRp), has broad antiviral activity against human and animal coronaviruses. Using mouse hepatitis virus (MHV) and human coronavirus NL63 (HCoV-NL63) as a model, we show that ATV006 has potent prophylactic and therapeutic activity against murine coronavirus infection in vivo. Remarkably, ATV006 successfully inhibits viral replication in mice even when administered 96 h after infection. Due to its oral bioavailability and potency against multiple coronaviruses, ATV006 has the potential to become a useful antiviral agent against SARS-CoV-2 and other circulating and emerging coronaviruses in humans and animals.

Colorectal tumorigenesis generally progresses from adenoma to adenocarcinoma, accompanied by dynamic changes in the tumor microenvironment (TME). A randomized controlled trial has confirmed the efficacy and safety of Shen-Bai-Jie-Du decoction (SBJDD) in preventing colorectal tumorigenesis. However, the mechanism remains unclear. In this study, we employed single-cell RNA sequencing (scRNA-seq) to investigate the dynamic evolution of the TME and validated cell infiltration with multiplex immunohistochemistry and flow cytometry. Bulk RNA sequencing was utilized to assess the underlying mechanisms. Our results constructed the mutually verifiable single-cell transcriptomic atlases in Apc ^Min/+ mice and clinical patients. There was a marked accumulation of CCL22⁺ dendritic cells (DCs) and an enhanced immunosuppressive action, which SBJDD and berberine reversed. Combined treatment with cholesterol and lipopolysaccharide induced characteristic gene expression of CCL22⁺ DCs, which may represent "exhausted DCs". Intraperitoneal injection of these DCs after SBJDD treatment eliminated its therapeutic effects. TMEM131 derived CCL22⁺ DCs generation by TNF signaling pathway and may be a potential target of berberine in retarding colorectal tumorigenesis. These findings emphasize the role of exhausted DCs and the regulatory mechanisms of SBJDD and berberine in colorectal cancer (CRC), suggesting that the multi-component properties of SBJDD may help restore TME homeostasis and offer novel cancer therapy.

Objective:To study the application effect of perioperative management based on enhanced recovery after surgery(ERAS)philosophy in the robot-assisted surgery for thoracolumbar fracture.Methods:This was a prospective random control trial(RCT).A total of 80 patients with thoracolumbar fracture admitted to Jiangsu Provincial People's Hospital from January 2020 to January 2025 were selected.They were divided into control group and ERAS group according to random number method,with 40 cases in each group.All of them adopted robot-assisted surgery for thoracolumbar fracture as the main therapeutic scheme.After surgery,the control group adopted routine perioperative management,and the ERAS group adopted perioperative management based on the ERAS philosophy.The postoperative recovery time of physiological function(the time for removing urinary catheter,time for eating,time for exhaling,time for getting out of bed,and length of hospital stay)between two groups were compared.The self-rating anxiety scale(SAS)and self-rating depression scale(SDS)were applied to assess the levels of anxiety and depression of the patients in two groups before surgery and at the 1st d,5th d and 7th d after surgery.In addition,the pain score of visual analogue scale(VAS),the incidence of postoperative complication,the scores of psychological state before and at the 7th day after surgery,and patient's satisfaction for diagnosis and treatment during the length of hospital stay as the evaluation of Nursing Scale for Nursing Staff(NSNS)before discharge were compared between the two groups.Results:The time for removing urinary catheter,time for eating,time for exhaling,time for getting out of bed,and length of hospital stay of ERAS group were shorter than those of control group,and the differences were significant(t=3.508,9.171,5.423,10.983,6.675,P<0.05).Before surgery,there were not significant differences in VAS score,SAS score and SDS score between the two groups(P>0.05).The VAS scores at the 1st d,5th d and 7th d after surgery in ERAS group were significantly lower than those in control group(t=5.433,5.882,5.060,P<0.05).At the 7th d after surgery,the scores of SAS and SDS in ERAS group significantly decreased,which were significantly lower than those in control group(t=14.327,13.390,P<0.05).The incidence of postoperative complications in ERAS group was 7.50%(3/40),which was lower than 32.50%(13/40)in control group(x2=7.812,P<0.05).Satisfaction of patients in ERAS group was 95.00%,which was significantly higher than 77.50%in control group(x2=5.165,P<0.05).Conclusion:The perioperative management based on ERAS philosophy can contribute to promote the recovery of postoperatively physiological function,and relieve postoperative pain,and improve postoperatively negative emotional state,and reduce the incidence of postoperative complications,and enhance patient's satisfaction.
