Hepatocellular carcinoma （HCC）， the predominant subtype of primary liver cancer， ranks among the top in both incidence and mortality rates of malignant tumors in China. In its early stages， the disease may present with subtle or nonspecific symptoms， often leading to poor clinical prognosis and low patient survival rates， which makes it a significant public health concern. The pathogenesis is associated with multiple factors， including hepatitis virus infection， alcohol consumption， obesity， drug-induced liver injury， and immune disorders， which may interact synergistically to promote disease development. Currently， mainstream therapeutic approaches for HCC in modern medicine encompass surgical resection， liver transplantation， radiofrequency ablation， radiotherapy， and chemotherapy， but they all have certain limitations， such as large side effects and poor prognosis， imposing substantial psychological distress and financial strain on affected individuals. With a rich historical background in hepatic malignancy management， traditional Chinese medicine offers therapeutic benefits characterized by multi-targeted mechanisms， multi-level regulation， minimal adverse effects， and reduced likelihood of disease recurrence. It can not only enhance the curative effect， but also reduce the side effects of radiotherapy， chemotherapy， and surgery. Thus， it has attracted widespread attention. Extensive research has demonstrated that traditional Chinese medicine exhibits significant antitumor properties， along with notable anti-inflammatory and oxidative stress-reducing capabilities， and its mechanism may be related to the regulation of nuclear factor-kappa B （NF-κB） signaling pathway， which can affect multiple stages of hepatocarcinogenesis， such as cell proliferation， invasion， metastasis， and apoptosis. The mechanism of NF-κB signaling pathway in traditional Chinese medicine for HCC treatment has emerged as one of the pivotal research directions in current oncology studies. Based on the existing research foundation， a systematic literature review method was adopted to retrieve and analyze relevant Chinese and English literature in recent years. Integrating the molecular regulatory mechanisms of the NF-κB signaling pathway and its pivotal role in HCC pathogenesis and progression helped further explore the latest research advances in traditional Chinese medicine interventions targeting this pathway for HCC treatment. This approach may provide novel theoretical foundations and translational strategies for the prevention and management of HCC using traditional Chinese medicine.

Objective To study the relationship between serum insulin-like growth factor-1 (IGF-1) and resistin levels and osteoporosis in patients with type 2 diabetes mellitus (T2DM). Methods This study was conducted on 306 T2DM patients admitted to Baoding No.2 Central Hospital from January 2018 to January 2022. According to the detection results of bone mineral density, the patients were divided into osteoporosis group (T≤-2.5) and non-osteoporosis group (T>-2.5). The differences in IGF-1, resistin and bone mineral density were compared between the two groups. Pearson correlation analysis was used to analyze the correlation between serum IGF-1 and resistin levels and bone mineral density in patients with osteoporosis. Receiver operating characteristic (ROC) curve was applied to evaluate the application value of IGF-1 and resistin in predicting osteoporosis in patients with T2DM. Patients with T2DM complicated with osteoporosis were followed up for 2 years, and the occurrence of fractures was assessed. After univariate analysis, multivariate logistic regression analysis was applied to screen the risk factors for fractures in T2DM patients with osteoporosis. Results The incidence rate of osteoporosis in patients with T2DM was 53.59% (164/306). The IGF-1 level and bone mineral density level in the osteoporosis group were lower than those in the non-osteoporosis group, while the level of resistin was higher than that in the non-osteoporosis group (P<0.05). Serum IGF-1 in patients with osteoporosis was positively correlated with bone mineral density, and serum resistin was negatively correlated with bone mineral density (P<0.05). The AUC, sensitivity and specificity of combination of IGF-1 and resistin in predicting osteoporosis were 0.888, 82.93% and 62.68% respectively, which were all higher than those of single factor prediction (P<0.05). The 164 T2DM patients with osteoporosis were followed up for two years, and 15 patients developed fragility fractures, with the incidence of fracture of 9.15% (15/164). Multivariate analysis showed that hypoproteinemia, high-intensity exercise, lack of nutritional management, low IGF-1, and high resistin were risk factors for fractures in patients with T2DM complicated with osteoporosis (P<0.05). Conclusion For patients with T2DM, the incidence rates of osteoporosis and fractures are high. The levels of IGF-1 and resistin are closely related to bone mineral density, which can be combined to predict osteoporosis. Hypoproteinemia, high-intensity exercise, lack of nutritional management, low IGF-1 and high resistin are risk factors for fractures in T2DM patients with osteoporosis. It is necessary to carry out targeted preventive measures in clinical practice to reduce the incidence rate of fractures.

Objective:To investigate the clinical characteristics of multiple sclerosis (MS) patients with positive anti-SSA antibody.Methods:The data of patients with positive anti-SSA antibody hospitalized in Beijing Tiantan Hospital between December 2011 and May 2020 were retrieved. Patients who fulfilled the diagnosis of MS were enrolled. MS patients with negative anti-SSA antibody hospitalized in the same period were matched based on gender and age in a ratio of 1∶2. The clinical characteristics of MS patients with positive anti-SSA antibody and those with negative anti-SSA antibody were compared. We used SPSS 24.0 statistical software to perform data analysis. The Shapiro-Wilk test was used to determine whether continuous variables conform to a normal distribution. The group differences of non-normal distribution of measurement data were analyzed by Mann-Whitney U test. Fisher exact probability method was used to compare the group differences of categorical variables. P<0.05 was considered statistically significant.Results:There were 785 hospitalized patients with anti-SSA positivity. Among these, a total of 7 patients (0.89%) were diagnosed as MS. Fourteen MS patients with negative anti-SSA antibody were included with matched sex and age. There was a statistical significant difference in the frequency of positive antinuclear antibody (ANA)and anti-Ro-52 antibody between MS patients with positive anti-SSA antibody and those with negative anti-SSA (6/7 vs. 0/14, P<0.001; 4/7 vs. 0/14, P=0.006, respectively). No statistical significant difference in other clinical features was detected between the two groups (P>0.05).Conclusion:The frequency of ANA and anti-Ro-52 antibody positivity is significantly higher in MS patients with positive anti-SSA antibody. Our results suggest the presence of positive anti-SSA antibody has no affect on clinical features of MS. The relationship between MS and anti-SSA positivity may be incidently coexisted.

Objective:To explore the association between polymorphisms of transforming growth factor-β(TGF-β)signaling pathway and non-syndromic cleft lip with or without cleft palate(NSCL/P)among Asian populations,while considering gene-gene interaction and gene-environment interaction.Methods:A total of 1 038 Asian NSCL/P case-parent trios were ascertained from an international consortium,which conducted a genome-wide association study using a case-parent trio design to investigate the genes affec-ting risk to NSCL/P.After stringent quality control measures,343 single nucleotide polymorphism(SNP)spanning across 10 pivotal genes in the TGF-β signaling pathway were selected from the original genome-wide association study(GWAS)dataset for further analysis.The transmission disequilibrium test(TDT)was used to test for SNP effects.The conditional Logistic regression models were used to test for gene-gene interaction and gene-environment interaction.Environmental factors collected for the study in-cluded smoking during pregnancy,passive smoking during pregnancy,alcohol intake during pregnancy,and vitamin use during pregnancy.Due to the low rates of exposure to smoking during pregnancy and al-cohol consumption during pregnancy(＜3％),only the interaction between maternal smoking during pregnancy and multivitamin supplementation during pregnancy was analyzed.The threshold for statistical significance was rigorously set at P=1.46 × 10-4,applying Bonferroni correction to account for multiple testing.Results:A total of 23 SNPs in 4 genes yielded nominal association with NSCL/P(P＜0.05),but none of these associations was statistically significant after Bonferroni's multiple test correction.How-ever,there were 6 pairs of SNPs rs4939874(SMAD2)and rs1864615(TGFBR2),rs2796813(TGFB2)and rs2132298(TGFBR2),rs4147358(SMAD3)and rs1346907(TGFBR2),rs4939874(SMAD2)and rs1019855(TGFBR2),rs4939874(SMAD2)and rs12490466(TGFBR2),rs2009112(TGFB2)and rs4075748(TGFBR2)showed statistically significant SNP-SNP interaction(P＜1.46 × 10-4).In contrast,the analysis of gene-environment interactions did not yield any significant results after being cor-rected by multiple testing.Conclusion:The comprehensive evaluation of SNP associations and interac-tions within the TGF-β signaling pathway did not yield any direct associations with NSCL/P risk in Asian populations.However,the significant gene-gene interactions identified suggest that the genetic architec-ture influencing NSCL/P risk may involve interactions between genes within the TGF-β signaling path-way.These findings underscore the necessity for further investigations to unravel these results and further explore the underlying biological mechanisms.
