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 establish reference values for clot waveform analysis (CWA) and analyze their diagnostic efficacy in distinguishing acquired hemophilia A (AHA) and lupus anticoagulant (LA)-positive patients.Methods:Case-Control Study. A total of 391 healthy individuals(260 males and 131 females) with a mean age of 45.53±14.85 years were enrolled at Nanyang central Hospital between January 6, 2023 and October 10, 2024. Prothrombin time (PT), activated partial thromboplastin time (APTT), and thrombin time (TT) were measured to establish reference ranges for the CWA parameters, including maximal reaction velocity (Min1), maximal reaction acceleration (Min2), and maximal reaction deceleration (Max2). A total of 158 definitively diagnosed AHA and LA-positive patients (mean age:42.46±14.83 years), including 34 AHA patients and 124 LA-positive patients, were recruited. The Mann Whitney U test was used to analyze the differences in the CWA parameters between the two groups. The diagnostic efficacy of CWA parameters in distinguishing AHA and LA-positive patients was evaluated using the area under the receiver operating characteristic(ROC) curve AUC and the cut-off values were calculated. Results:The reference values for PT-Min1, APTT-Min1, APTT-Min2, APTT-Max2, TT-Min1, TT-Min2, TT-Max2 were 203.41-516.89, 144.63-324.03, 526.46-1 190.03, -404.96±157.22, 159.17±60.34, 272.29-686.99, and -289.47--113.76, respectively. Compared with the CWA parameters in AHA patients, APTT-Max2 was significantly lower in LA-positive patients [-422.74(-577.50, -239.22) vs. -68.87(-92.85,30.28), Z=-7.43, P<0.01], while PT-Min1, APTT-Min1, APTT-Min2, TT-Min1, TT-Min2 were significantly elevated [287.01(188.03, 382.50) vs. 107.45(90.20, 151.39), 972.88(601.20, 1 351.19) vs. 229.10(118.38, 371.67), Z=6.68, 6.69, all P<0.01]. ROC analysis demonstrated the APTT-CWA parameter exhibited high diagnostic efficacy in patients with AHA (AUC>0.900 for both).Additionally, APTT-Min1 and APTT-Max2 were found to be useful in distinguishing between AHA patients and those with LA-positive status accompanied by APTT prolongation (AUC=0.660, 0.700, respectively). Conclusions:Reference values for CWA parameters were successfully established. The APTT-CWA is useful for differentiating between AHA and LA-positive patients and APTT-Max2 demonstrated a good diagnostic value in differentiating AHA patients from those with LA-positive status accompanied by APTT prolongation.

Objective: To identify the phenotypes, antibodies and explore the molecular mechanisms of a patient who carries antibodies to RBC high-frequency antigens and his family members. Methods: The antibody identification test was performed for the proband by serological methods, and targeted NGS was subsequently used to detect mutations that occurred in blood group genes. Blood samples were collected from the proband and his family members. Sanger sequencing was used to verify the mutation of the XK gene. The expression of Kell blood group antigens was detected by serological methods and flow cytometry. K
cells were used to detect the antibody specificity of the proband. The morphology of red blood cells was detected by the scanning electron microscopy. The serum creatine kinase levels of the proband and his family members were analyzed by colorimetric methods. Results: The results of the antibody identification test suggested that the proband might have antibodies to high-frequency antigens. NGS results suggested a homozygous mutation (c. 107G>A) in exon 1 of the XK gene in the proband, resulting in a truncated XK protein. The Sanger sequencing results of the proband were consistent with the NGS results, and the mutation was not found in other family members. The expression of Kell blood group antigens of the proband was not found by serological methods and flow cytometry. The results of the antibody specificity test showed that the proband had anti-Km antibodies. Spike-like changes were identified on red blood cells, and serum creatine kinase level was elevated in the proband. Conclusion: In this study, the McLeod phenotype caused by homozygous mutation (c. 107G>A) of XK gene was identified in Chinese individuals for the first time by the phenotype and molecular mechanism studies. The results of genotyping and phenotyping suggested that the McLeod phenotype caused by the mutation was compatible with the phenotypes of McLeod and K

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.

Hepatic encephalopathy is a neuropsychiatric syndrome secondary to severe liver disease.Recent studies have shown that the development of hepatic encephalopathy is closely associated with bile acid/short-chain fatty acid metabolic disorder.As the core theory of traditional Chinese medicine,the theory of Yin and Yang provides a unique perspective for analyzing the association between bile acids/short-chain fatty acids and hepatic encephalopathy.Bile acids function like Yang,governing the free flow of Qi and assisting in metabolic processes,while short-chain fatty acids belong to Yin,maintaining internal stability and conservation,preserving the intestinal barrier,and combating inflammation and toxins.Bile acids and short-chain fatty acids constrain each other and are interdependent to regulate the dynamic equilibrium of the gut-liver-brain axis.On this basis,by regulating the metabolic imbalance of bile acids and short-chain fatty acids,it is expected to restore the dynamic balance of Yin and Yang in patients with hepatic encephalopathy under the synergistic intervention of traditional Chinese medicine and Western medicine.

Objective:To explore the mechanism of herb-partitioned moxibustion in relieving rat intestinal inflammation by focusing on the neutrophil extracellular traps(NETs)in Crohn disease(CD)development. Methods:Rats were randomly divided into a normal group,a model group,a herb-partitioned moxibustion group,and a mesalazine group.The CD rat model was prepared with 2,4,6-trinitrobenzene sulfonic acid except for rats in the normal group.Rats in the normal group and model group did not receive any treatment but had the same fixation as the other groups.Rats in the herb-partitioned moxibustion group received herb-partitioned moxibustion at Qihai(CV6)and bilateral Tianshu(ST25).Rats in the mesalazine group received intragastric administration of mesalazine enteric-coated tablets.The general situation of rats in each group was recorded,and the histopathological changes in the colon were observed and scored by hematoxylin-eosin staining.The serum concentrations of NETs DNA(NETs-DNA),neutrophil elastase(NE)-DNA,and myeloperoxidase(MPO)-DNA were detected by ABC enzyme-linked immunosorbent assay,and the citrullinated histone 3(citH3),MPO,and NE protein and mRNA expression levels in rat colon tissue were observed by immunofluorescence and real-time quantitative polymerase chain reaction. Results:Compared with the normal group,the mucosal ulcer reached the muscularis,the epithelium was incomplete,the goblet cells decreased obviously with significant inflammatory cell infiltration in the colon;the colonic mucosa damage index(CMDI)score increased significantly(P<0.01);the serum NETs-DNA,NE-DNA,and MPO-DNA concentrations increased(P<0.05);the NE,citH3,and MPO protein and mRNA expression in the colonic tissue increased significantly in the model group(P<0.01 or P<0.05).Compared with the model group,the mucosal epithelium in the herb-partitioned moxibustion group and the mesalazine group was repaired and the goblet cells increased with a few infiltrating inflammatory cells in the colon;the CMDI score decreased(P<0.01);the serum NETs-DNA,NE-DNA,and MPO-DNA concentrations decreased(P<0.05);the NE,citH3,and MPO protein and mRNA expression in the colonic tissue was down-regulated(P<0.01 or P<0.05). Conclusion:Herb-partitioned moxibustion reduced the serum NETs complex and inhibited the protein and mRNA expression of NETs complex in the colon tissue,which may be one mechanism of herb-partitioned moxibustion in relieving colon mucosal inflammation in CD.
