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.

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.

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.

Objective:To develop a clinical automated diagnostic system for temporomandibular disor-ders(TMD)based on the diagnostic criteria for TMD(DC/TMD)to assist dentists in making rapid and accurate clinical diagnosis of TMD.Methods:Clinical and imaging data of 354 patients,who visited the Center for TMD & Orofacial Pain at Peking University Hospital of Stomatology from September 2023 to January 2024,were retrospectively collected.The study developed a clinical automated diagnostic system for TMD using the DC/TMD,built on the.NET Framework platform with branching statements as its in-ternal structure.Further validation of the system on consistency and diagnostic efficacy compared with DC/TMD were also explored.Diagnostic efficacy of the TMD clinical automated diagnostic system for de-generative joint diseases,disc displacement with reduction,disc displacements without reduction with limited mouth opening and disc displacement without reduction without limited mouth opening was evalua-ted and compared with a specialist in the field of TMD.Accuracy,precision,specificity and the Kappa value were assessed between the TMD clinical automated diagnostic system and the specialist.Results:Diagnoses for various TMD subtypes,including pain-related TMD(arthralgia,myalgia,headache attribu-ted to TMD)and intra-articular TMD(disc displacement with reduction,disc displacement with reduc-tion with intermittent locking,disc displacement without reduction with limited opening,disc displace-ment without reduction without limited opening,degenerative joint disease and subluxation),using the TMD clinical automated diagnostic system were completely identical to those obtained by the TMD spe-cialist based on DC/TMD.Both the system and the expert showed low sensitivity for diagnosing degenera-tive joint disease(0.24 and 0.37,respectively),but high specificity(0.96).Both methods achieved high accuracy(＞0.9)for diagnosing disc displacements with reduction and disc displacements without reduction with limited mouth opening.The sensitivity for diagnosing disc displacement without reduction without limited mouth opening was only 0.59 using the automated system,lower than the expert(0.87),while both had high specificity(0.92).The Kappa values for most TMD subtypes were close to 1,ex-cept the disc displacement without reduction without limited mouth opening,which had a Kappa value of 0.68.Conclusion:This study developed and validated a reliable clinical automated diagnostic system for TMD based on DC/TMD.The system is designed to facilitate the rapid and accurate diagnosis and classi-fication of TMD,and is expected to be an important tool in clinical scenarios.

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 establish colorectal cancer LoVo and SW620 cell lines that stably interfere with the expression of LINC01224, and to explore the effect of down-regulating the expression of LINC01224 on cell apoptosis. Methods: The GEPIA2 database was used to analyze the expression of LINC01224 in colorectal cancer tissues; qPCR method was used to detect the expression of LINC01224 in 10 human colorectal cancer cells. Three different LINC01224 siRNAs were respectively transfected into human colorectal cancer LoVo cells, and the LINC01224 shRNA lentiviral vector was constructed with the siRNA sequence with the most obvious inhibitory effect of LINC01224 expression. Recombinant lentiviral particles were packaged in HEK293 T cells and then infected with LoVo and SW620 cells. After selection by puromycin, the monoclonal cells that stably interfere with LINC01224 were obtained by limiting dilution method. MTS method detects cell proliferation ability, and flow cytometry detects cell apoptosis rate. Results: The expression of LINC01224 in colorectal cancer tissues was higher than that in normal colorectal tissues, and its expression in 10 types of colorectal cancer cells was also higher than that in normal colorectal epithelial cells HCOEPic. The inhibition rate of siRNA-3 on the expression of LINC01224 in LoVo cells was higher than that of siRNA-1 and siRNA-2. Therefore, siRNA-3 was chosen to design LINC01224 shRNA.Compared with the control group(sh-NC group), the expression level of LINC01224 in the LoVo and SW620 cells of the stable interference LINC01224 group(sh-LINC01224 group) was reduced(P<0.01), and the cell growth rate was slowed down(P<0.01), the rate of apoptosis also increased(P<0.01). Conclusion The shRNA lentiviral interference vector of LINC01224 is successfully constructed, which can stably infect LoVo and SW620 cells, down-regulate the expression of LINC01224 and induce cell apoptosis.

Objective To analyze the law of the mid﹣term hepatic hemodynamics after liver transplantation and to investigate its relationship with liver function. Methods A total of 56 recipients underwent liver transplantation in the Affiliated Hospital of Qingdao University from February 2014 to October 2015 were studied,and divided into normal group (n =24)and abnormal group (n =32)according to the liver function.General information and liver function of both groups were recorded.Furthermore,hepatic artery peak velocity (HAP),portal vein peak velocity (PVP)and portal vein flow (PVF)before the liver transplantation and on postoperative day 1,30 and 90 were measured through ultrasonic detection;hepatic arterial buffer capacity (BC)and adjustment BC were calculated.The univariable and multivariable analysis were performed to analyze the relationship between hepatic hemodynamics and liver function in two groups,and the receiver operating curve (ROC)was drawn. Results The PVP and PVF on postoperative day 30 in abnormal group were significantly higher than those of normal group (P =0.014,0.049).The BC and adjustment BC in normal group were significantly higher than those of abnormal group (P =0.048,0.011).The multivariable analysis showed that adjustment BC was the independent risk factor (P =0.047),with the area under the curve (AUC)of ROC of 0.705,sensitivity of 0.652 and specificity of 0.750. Conclusions PVP,PVF,BC and adjustment BC on postoperative day 30 may be related to abnormal liver function,of which adjustment BC can be used as one of the indicators for diagnosis and intervention of abnormal liver function.
