Hepatic encephalopathy （HE） is a common complication of severe liver disease in the end stage， and it is urgently needed to improve the rate of effective treatment and clarify the pathogenesis of HE. The liver is a crucial hub for immune regulation， and disruption of immune homeostasis is a key factor in the pathological mechanisms of HE. As the main metabolites of intestinal flora， short-chain fatty acids （SCFAs） play a vital role in the biological processes of both innate and adaptive immunity and can regulate the proliferation and differentiation of immune cells maintain the homeostasis of intestinal microenvironment and the integrity of barrier function. Studies have shown that SCFAs participate in bidirectional and dynamic interactions with the liver-gut-brain axis through immunomodulatory pathways， thereby playing an important role in the diagnosis， treatment， and prognostic evaluation of HE. Starting from the immunoregulatory effect of SCFAs， this article summarizes and analyzes the crosstalk relationship between SCFAs and the liver-gut-brain axis and the significance of SCFAs in the diagnosis and treatment of HE， in order to provide new ideas for optimizing clinical prevention and treatment strategies.

Nuclear factor-kappa B （NF-κB） is an important intracellular transcription factor widely involved in the processes such as immune response， inflammatory response， cell proliferation， and apoptosis. The abnormal activation of the NF-κB signaling pathway plays a pivotal role in various liver diseases including chronic hepatitis， liver fibrosis， liver cirrhosis， and hepatocellular carcinoma. Extensive studies have shown that inhibiting NF-κB activity may effectively reduce inflammation and fibrosis and improve metabolic disorders. Several natural compounds， such as matrine and salvianolic acid B， have shown the potential in suppressing NF-κB activity， thereby exerting anti-inflammatory， anti-fibrotic， and anti-tumor effects. This article systematically reviews the critical role of the NF-κB signaling pathway in liver diseases and its potential as a therapeutic target， in order to highlight its potential as a therapeutic target for liver diseases and provide new directions for the treatment of liver diseases.

BACKGROUND: The transcription factor POU2F1 regulates the expression levels of microRNAs in neoplasia. However, the miR-29b1/a cluster modulated by POU2F1 in gastric cancer (GC) remains unknown. METHODS: Gene expression in GC cells was evaluated using reverse-transcription polymerase chain reaction (PCR), western blotting, immunohistochemistry, and RNA in situ hybridization. Co-immunoprecipitation was performed to evaluate protein interactions. Transwell migration and invasion assays were performed to investigate the biological behavior of GC cells. MiR-29b1/a cluster promoter analysis and luciferase activity assay for the 3'-UTR study were performed in GC cells. In vivo tumor metastasis was evaluated in nude mice. RESULTS: POU2F1 is overexpressed in GC cell lines and binds to the miR-29b1/a cluster promoter. POU2F1 is upregulated, whereas mature miR-29b-3p and miR-29a-3p are downregulated in GC tissues. POU2F1 promotes GC metastasis by inhibiting miR-29b-3p or miR-29a-3p expression in vitro and in vivo . Furthermore, PIK3R1 and/or PIK3R3 are direct targets of miR-29b-3p and/or miR-29a-3p , and the ectopic expression of PIK3R1 or PIK3R3 reverses the suppressive effect of mature miR-29b-3p and/or miR-29a-3p on GC cell metastasis and invasion. Additionally, the interaction of PIK3R1 with PIK3R3 promotes migration and invasion, and miR-29b-3p , miR-29a-3p , PIK3R1 , and PIK3R3 regulate migration and invasion via the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway in GC cells. In addition, POU2F1 , PIK3R1 , and PIK3R3 expression levels negatively correlated with miR-29b-3p and miR-29a-3p expression levels in GC tissue samples. CONCLUSIONS The POU2F1 - miR-29b-3p / miR-29a-3p-PIK3R1 / PIK3R1 signaling axis regulates tumor progression and may be a promising therapeutic target for GC.

Hepatocellular carcinoma （HCC） is a malignant tumor with high incidence and mortality rates worldwide. Recent studies have shown that neutrophil extracellular traps （NETs） play an important role in the development， progression， and immune escape of HCC. NETs are released by neutrophils and mainly consist of DNA， histones， and antimicrobial molecules， and in addition to immune defense， they are also involved in the initiation， metastasis， and thrombosis of HCC. This article elaborates on the formation and regulatory mechanisms of NETs， explores their potential mechanisms in the initiation， metastasis， immune escape， and thrombosis of HCC， and discusses the prospect of NETs as a target for the diagnosis and treatment of HCC， in order to provide new ideas for the precise treatment of HCC in the future and promote the early diagnosis and effective treatment of HCC.

Objective:To explore the clinical safety and effectiveness of self-draining ureteral stent with thread in kidney transplant recipients in renal transplantation.Methods:This study is a prospective cohort clinical study in the Department of Urology of Peking University People's Hospital from November 2022 to January 2024.The ureteral stent with thread group,in which a 2-0 Mersilene suture of 20-30 cm was used at the bladder end of the ureteral stent during the operation.On the 9th day after the opera-tion,the suture attached to the end of the ureteral stent was expelled out of the urethral orifice with the urine when the catheter was removed.The ureteral stent could be removed along with the suture.As to the cystoscope group,a ureteral stent was routinely placed during kidney transplantation,and the ureteral stent was removed under local infiltration anesthesia through cystoscopy after the operation.The pain scores[numerical rating scale(NRS)-11]during catheter removal and the incidence of urinary tract in-fections were observed and compared between the two groups.t test was used to compare the pain scores of indwelling ureteral stents and ureteral stents removal between the two groups,and Chi-square test was used to compare the occurrence of urinary system complications within 3 months after operation between the two groups.P＜0.05 was considered statistically significant.Results:As of March 2024,all the re-cipients were followed up for an average of 6 months(3 to 12 months)postoperatively.A total of 46 kid-ney transplantation patients were included,with 21 in the ureteral stent with thread group and 25 in the cystoscope group.There were no statistically significant differences between the two groups in age distri-bution,male-to-female ratio,and deceased versus live donor grafts.Three months after renal transplanta-tion,there were 15 cases of urinary tract infection in the cystoscope group and 4 cases in the ureteral stent with thread group(P=0.007).No significant urinary fistula,wound infection,or ureteral stenosis occurred in either group.No stent-related complications,stent migration,or stone formation were ob-served.The postoperative bladder spasm symptom scores for indwelling ureteral stents in the cystoscope group and the ureteral stent with thread group were 4.4±2.5 and 4.6±2.4,respectively,with no sta-tistically significant difference(t=0.29,P=0.773).However,the pain scores during ureteral stent re-moval were 4.9±1.6 and 3.0±1.0 in the two groups,respectively,with a statistically significant diffe-rence(t=5.017,P＜0.001).The total costs of indwelling and removing ureteral stents in the cystosco-py group and the ureteral stent with thread group were 6 452.0(5 539.5,6 452.0)yuan and 3 225.0(3 225.0,3 225.0)yuan,respectively,and the difference was statistically significant(P＜0.001).Conclusion:Compared with the conventional transplanted kidney ureteral stent,the self-discharge ure-teral stent technique with sutures is simpler,has a shorter ureteral stent inlay time,reduces the symptoms of bladder spasms,significantly reduces the cost of catheterization,and has fewer postoperative urinary system complications.It is a worthy improved surgical method to be promoted.

Objective To explore the public's cognition and attitude towards general medicine,general practitioners,and pre-hospital first-aid knowledge in Ludian County,Yunnan Province,to find out the training and learning methods that are more acceptable to the public for this kind of related knowledge,and to propose targeted solutions.Methods A complete random sampling survey was conducted among the nucleic acid collection office at the gate of the vegetable market from October 15,2022,to December 30,2022,and the outpatient clinic of Wenping Street Health Center from January 1,2023,to February 28,2023,by using electronic questionnaire and paper questionnaire.Results Nearly 50%of the people in Ludian County of Yunnan Province lack the knowledge of general medicine and pre-hospital emergency care,especially the knowledge of electrical defibrillation.People with higher education and the medical profession have a higher understanding of general medicine,and people with a higher understanding of general medicine are more willing to participate in pre-hospital emergency care.The average Ridit value is:very familiar with general medicine(0.774)>Knowledge of some general practices(0.565)>Never heard of general practice(0.400).The higher education level and the more comprehensive understanding of general medicine had a positive impact on participation in pre-hospital emergency care,with B values of 0.624 and 0.619,OR 95%CI of 1.867(1.544～2.257)and 1.857(1.298～2.657),respectively.Taking medical staff as a reference,the B value of medical students was = 0.942,P = 0.234,the difference was not significant,and the B value of non-medical professional population was all less than 0,the effect is negative.In addition,most people have a positive attitude towards learning pre-hospital first aid,and more than 70%of people are willing to learn and train related knowledge of pre-hospital first aid.Conclusions People in urban areas of Ludian County,Yunnan Province have poor understanding of general practice,low recognition of general practitioners,low demand for general practitioners,and lack of awareness of the importance of pre-hospital emergency treatment.Because of the cognitive differences among different groups,it is necessary to conduct specific training for different groups.

Objective To investigate the effect of Liraglutide on alleviating the liver injury inmice with DM,and to evaluate the effects of Liraglutide on liver fibrosis,liver aging and liver oxidative stress.Methods Thirty C57BL/6J mice were randomly divided into normal control group(Con),model group(Mod)and Liraglutide group(Lir),with 10 mice in each group.The expressions of p21,p16,p53,inflammatory factors TNF-α and IL-1β were detected by Western blot.The effects of Liraglutide on liver fibrosis were analyzed by Masson and Sirius scarlet staining.The oxidative stress Lndexes of reactive oxygen species(ROS),superoxide dismutase(SOD)and malondialdehyde(MDA)were compared among the groups.Results The expressions of TNF-α,IL-6,IL-1β,NLRP3,p16,p21,p53,p15,TNF-α,IL-6,IL-1β,NLRP3 and α-SMA were higher in Mod group than in Con and Lir groups(P<0.05).ROS and MDA were higher,while SOD and GSH-PX were lower in Mod group than in Con and Lir group(P<0.05).The positive areas of Sirius scarlet and Masson staining were higher in Mod group than in Con and Lir groups(P<0.05).Conclusions Liraglutide can alleviate liver aging,inflammation and fibrosis,and has protective effect on liver injury caused by DM.

Objective:To investigate the clinical significance of a new classification system for atlas fractures based on pre- and post-treatment CT features, with a focus on diagnosis and treatment.Methods:A retrospective analysis was conducted on 75 cases of cervical vertebra fractures treated at the Sixth Hospital of Ningbo City between January 2015 and December 2020. The study included 44 males and 31 females, with an average age of 53.3±13.0 years (range: 27-81 years). The fractures were classified according to the Landells classification, resulting in 12 cases of type I, 13 cases of type II, 33 cases of type III, 9 cases that were difficult to classify due to fracture lines located at anatomical junctions, and 8 cases that could not be classified using the Landells classification due to diverse injury mechanisms. To establish a new preliminary classification for cervical vertebra fractures, the researchers considered whether the fracture line in the CT images involved the facet joint surface of the atlas, the impact on bilateral half-rings, and the displacement distance of the fracture ends. Five spinal surgeons were randomly selected to classify the CT images of the 75 patients using the new classification method. After one month, the imaging data of the 75 cases of cervical vertebra fractures were randomized and reclassified to assess the reliability and repeatability of the classification.Results:The new cervical vertebra fracture classification method comprised three types based on whether the fracture line involved the facet joint surface of the atlas: type A (no involvement of the facet joint surface of the atlas), type B (involvement of one side of the facet joint surface with intact contralateral half-ring), and type C (involvement of one side of the facet joint surface with fractured contralateral half-ring). Additionally, based on the maximum displacement distance between the fracture ends (>4 mm), six subtypes were identified: subtype 1 (≤4 mm displacement) and subtype 2 (>4 mm displacement). Consequently, the subtypes were classified as A1, A2, B1, B2, C1, and C2. According to the new classification method, the 75 patients included 17 cases of A1, 12 cases of A2, 7 cases of B1, 13 cases of B2, 12 cases of C1, and 14 cases of C2. The classification demonstrated excellent consistency, as assessed by the five doctors, with Kappa values of 0.85 and 0.91 for reliability and repeatability, respectively. At the final follow-up, all conservatively treated patients achieved bone healing, while four surgically treated patients experienced non-union of the fracture ends but exhibited good fusion between the atlas and axis. The remaining surgically treated patients achieved bony union without complications such as loosening or fracture of internal fixation.Conclusion:The new cervical vertebra fracture classification method, based on CT imaging features, comprehensively covers common clinical cases of cervical vertebra fractures and demonstrates excellent consistency. It provides valuable clinical guidance for the diagnosis and treatment of cervical vertebra fractures.
