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 investigate the association between social support and subjective and objective cognitive functions among the middle-aged and elderly population in Pingyin County, Jinan City, Shandong Province.Methods:Employing a multi-stage cluster random sampling method, a cross-sectional study was conducted in 2023 by selecting people aged 45-70 years from seven villages in three towns within Pingyin County, Jinan City, as survey respondents. Social Support Rating Scale (SSRS), Subjective Cognitive Decline-Questionnaire 9 (SCD-Q9) and Montreal Cognitive Assessment-Basic (MoCA-B) were used to assess the social support and cognitive status of interviewees, and a self-developed questionnaire was used to collect other basic information. Pearson correlation analysis, multiple linear regression and multifactorial logistic regression were used to explore the relationship between social support and subjective and objective cognitive functions.Results:A total of 1 891 subjects were finally included in the study, with 45.52±6.99 for the SSRS total score, an abnormal rate of 43.68% (826/1 891) for the SCD-Q9 score and an abnormal rate of 60.02% (1 135/1 891) for the MoCA-B score. The SSRS total score, subjective support score, objective support score and support utilization score were negatively correlated with SCD-Q9 scores and positively correlated with MoCA-B scores (all P<0.05). An increase in SSRS total score ( β=-0.034, 95% CI: -0.051--0.017, P<0.001) and objective support score ( β=-0.074, 95% CI: -0.121--0.027, P=0.002) can lower SCD-Q9 scores. Compared to those who had only 1 source of financial support or help with practical problems when experiencing an acute situation, those with 2-4 ( OR=0.53, 95% CI: 0.34-0.82), 5 ( OR=0.46, 95% CI: 0.27-0.79), or 6-7 ( OR=0.42, 95% CI: 0.22-0.81) sources of help were more likely to have normal SCD-Q9 scores. Compared to individuals with ≤2 close friends who provided support and help, those with 3-5 ( OR=0.67, 95% CI: 0.50-0.91) or ≥6 friends ( OR=0.72, 95% CI: 0.54-0.97) were more likely to have normal MoCA-B scores. Moreover, compared to individuals who never participated in group activities, those who actively participated ( OR=0.59, 95% CI: 0.42-0.81) were more likely to have normal MoCA-B scores. Conclusions:Social support has protective effects on subjective and objective cognitive functions, and various social support conditions have different protective effects on subjective and objective cognitive functions among middle-aged and older people. Improving social support conditions for middle-aged and elderly individuals may delay the process of cognitive decline.

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 investigate the predictive value of stone composition prediction method based on dual-source stone energy spectrum CT for uric acid stones.Methods:The clinical data of 204 patients with urinary stones, 159 males and 45 females, admitted to Shanghai Sixth People's Hospital from July 2020 to July 2022 were retrospectively analyzed. The average age was (50.7±14.3) years. There were 187 cases of upper urinary tract (kidney, ureter) stones and 17 cases of lower urinary tract (bladder, urethra) stones. All patients underwent preoperative dual-source stone energy spectroscopy CT, measuring CT values at 150 kV and 100 kV, respectively, and the calculated dual energy ratio (Ratio) was used to predict stone composition. Of the 204 cases in this group, 33 cases underwent percutaneous nephrolithotomy and 171 cases underwent ureteroscopic lithotripsy. Postoperative stone specimens were analyzed for stone composition by infrared spectroscopy. Subject work characteristic (ROC) curves were used to analyze the efficacy of preoperative dual-source stone energy spectrum CT to predict uric acid stones.Results:In 204 patients, preoperative CT predicted 28 cases of uric acid stones and 176 cases of non-uric acid stones, including 136 cases of calcium oxalate stones, 38 cases of hydroxyapatite, and 2 cases of cystine stones. Postoperative IR spectral analysis detected 26 cases of uric acid stones and 178 cases of non-uric acid stones, including 129 cases of calcium oxalate stones, 47 cases of hydroxyapatite, and 2 cases of cystine stones. Compared with the preoperative CT results, there were 2 false positives and no false negatives in the classification of uric acid stones. The ROC curve showed that the sensitivity of the CT value for predicting uric acid stones at 100 kV was 96.2%, the specificity was 99.5%, and the area under the ROC curve (AUC) was 0.995, with the best prediction value of 620 HU.The sensitivity of the CT value for predicting uric acid stones at 150 kV was 96.2%, specificity was 85.5%, AUC was 0.916, and the best predictive value was 597.5 HU. The sensitivity of using Ratio values for predicting uric acid stones was 100.0%, specificity was 97.9%, AUC was 0.996, and the best predictive value was 1.14. The CT values for uric acid stones at 100 kV and 150 kV were (558.58±77.07) HU and (521.12±83.54) HU, CT values for calcium oxalate stones were (1 335.26±301.82) HU and (878.21±200.21) HU, CT values for hydroxyapatite were (1 104.09±203.61) HU and (710.38±178.44) HU, respectively.The CT values of cystine stones were (684.5±67.18) HU and (573.5±67.10) HU, respectively, and the differences between uric acid stones and other components were statistically significant ( P<0.01). The Ratio values of uric acid stones, calcium oxalate stones, hydroxyapatite, and cystine stones were 1.08±0.06, 1.52±0.08, 1.62±0.40, and 1.19±0.02, respectively, and the differences were statistically significant ( P<0.01) when comparing uric acid stones with other components. Conclusion:The CT and Ratio values of dual-source stone energy spectrum CT can effectively distinguish uric acid stones from other types of stones, and the accuracy, sensitivity, and specificity of this method for predicting uric acid stones are high.
