Objective To observe the therapeutic effects and mechanism of Xiezhuo Qutong Formula on gout.Methods(1)Animal experiments:A hyperuricemia(HUA)model was established in SD rats using hypoxanthine combined with potassium oxonate,and an acute gouty arthritis(AGA)model was induced by monosodium urate.The efficacy and safety of Xiezhuo Qutong Formula in reducing serum uric acid levels and exerting anti-inflammatory effects were evaluated.(2)Network pharmacology:The main active components and potential targets of Xiezhuo Qutong Formula were collected,along with gout-related disease targets.The intersection of these targets yielded potential therapeutic targets.A protein-protein interaction(PPI)network was constructed,followed by Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis.Results Xiezhuo Qutong Formula effectively reduced serum uric acid levels in HUA model rats without observed hepatorenal toxicity.It also decreased joint inflammation index,joint swelling degree,and inflammatory cytokine levels in AGA model rats.Network pharmacology analysis identified 156 overlapping targets between the drug and disease,among which TP53,STAT3,PIK3CA,BCL2,PIK3CD,PIK3CB,JUN,HDAC1,ESR1,and RELA may be key targets of Xiezhuo Qutong Formula in treating gout.Combined with GO and KEGG enrichment analyses,the main involved pathways include PI3K/AKT,JAK2/STAT3,and NF-κB signaling pathways.Conclusion Xiezhuo Qutong Formula exerts uric acid-lowering and anti-inflammatory effects in the treatment of gout,and its potential mechanism involves the PI3K/AKT,JAK2/STAT3,and NF-κB signaling pathways.

The development, progression, and curative efficacy of head and neck squamous cell carcinoma (HNSCC) are influenced by complex interactions between epithelial and immune cells. Nevertheless, the specific changes in the nature of these interactions and their underlying molecular mechanisms in HNSCC are not yet fully understood. Cuproptosis, a form of programmed cell death that is dependent on copper, has been implicated in cancer pathogenesis. However, the understanding of cuproptosis in the context of HNSCC remains limited. In this study, we have discovered that cuproptosis-related long non-coding RNAs (CRLs) known as JPX play a role in promoting the expression of the oncogene urokinase-type plasminogen activator (PLAU) by competitively binding to miR-193b-3p in HNSCC. The increased activity of the JPX/miR-193b-3p/PLAU axis in malignant epithelial cells leads to enhanced cell proliferation, migration, and invasion in HNSCC. Moreover, the overexpression of PLAU in tumor epithelial cells facilitates its interaction with the receptor PLAUR, predominantly expressed on macrophages, thereby influencing the abnormal epithelial-immune interactome in HNSCC. Notably, the JPX inhibitor Axitinib and the PLAU inhibitor Palbociclib may not only exert their effects on the JPX/miR-193b-3p/PLAU axis that impacts the malignant tumor behaviors and the epithelial-immune cell interactions but also exhibit synergistic effects in terms of suppressing tumor cell growth and arresting cell cycle by targeting epidermal growth factor receptor (EGFR) and cyclin-dependent kinase (CDK4/6) for the treatment of HNSCC.

Objective To investigate the clinical significance of red blood cell distribution width-to-platelet ratio (RPR index) in evaluating the severity of metabolic-associated fatty liver disease and predicting fatty liver-associated cirrhosis. Methods A total of 192 patients with metabolic-associated fatty liver disease and 210 patients with fatty liver-associated cirrhosis who were admitted to Shengjing Hospital of China Medical University from January 2019 to June 2020 were enrolled as group A and group B, respectively, and 206 individuals who underwent physical examination in our hospital during the same period of time were enrolled as control group (group C). All subjects underwent general measurement, blood cell analysis, blood biochemical test, and abdominal CT examination, and related formulas were used to calculate RPR, aspartate aminotransferase-to-platelet ratio index (APRI), and fibrosis-4 (FIB-4) index. A one-way analysis of variance was used for comparison of continuous data with homogeneity of variance between groups, and the SNK method was used for comparison between two groups; the Kruskal-Wallis H test was used for comparison of continuous data with heterogeneity of variance between groups, and the Mann-Whitney U test was used for comparison between two groups; the chi-square test was used for comparison of categorical data between groups; the receiver operating characteristic (ROC) curve was used to analyze the accuracy of the prediction of liver cirrhosis. Results There were significant differences in red blood cell distribution width-standard deviation, albumin, creatinine, body mass index, RPR, and APRI between any two groups (all P < 0.001), and there were significant differences in white blood cell count, platelet count, alanine aminotransferase, aspartate aminotransferase, direct bilirubin, blood urea nitrogen, and FIB-4 between group A and group B (all P < 0.05). There were significant differences in waist circumference and fasting blood glucose between groups A and B and between groups A and C (all P < 0.001). There was a significant difference in RPR between any two groups of the mild, moderate, and severe metabolic-associated fatty liver disease groups (all P < 0.05). In terms of diagnostic efficiency, the three noninvasive models RPR, APRI, and FIB-4 had an area under the ROC curve of 0.932, 0.815, and 0.877, respectively, in predicting fatty liver-associated cirrhosis. Conclusion There is a difference in RPR index between different stages of liver disease, and RPR index gradually increases with the aggravation of metabolic-associated fatty liver disease. RPR index has a higher value than APRI and FIB-4 in the warning of fatty liver-associated cirrhosis.

Objective To investigate the value of triglyceride-glucose index (TyG) and body mass index (BMI) in predicting nonalcoholic fatty liver disease (NAFLD) in type 2 diabetes mellitus (T2DM). Methods A retrospective analysis was performed for the clinical data of 349 patients with T2DM who were treated in Shengjing Hospital of China Medical University from May 2020 to July 2021, and according to the presence or absence of NAFLD, they were divided into T2DM+NAFLD group with 213 patients and simple T2DM group with 136 patients. The t -test or the Mann Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. A logistic regression analysis was used to investigate the association of TyG and BMI with T2DM+NAFLD, and the receiver operating characteristic (ROC) curve was plotted to evaluate the prediction efficiency of TyG alone, BMI alone, and TYG combined with BMI for NAFLD in T2DM. The Kappa coefficient was used to analyze the consistency of prediction results. Results Compared with the simple T2DM group, the T2DM+NAFLD group had significantly higher BMI, diastolic pressure, fasting blood glucose, HbA1c, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, triglyceride, total cholesterol, low-density lipoprotein cholesterol, and TyG (all P < 0.05) and a significantly lower high-density lipoprotein cholesterol ( P < 0.05), while there were no significant differences between the two groups in systolic pressure, total bilirubin, direct bilirubin, and indirect bilirubin (all P > 0.05). The logistic regression analysis showed that TyG (odds ratio [ OR ]=6.513, 95% confidence interval [ CI ]: 1.884-22.517, P < 0.001) and BMI ( OR =1.369, 95% CI : 1.191-1.575, P < 0.001) were independent risk factors for NAFLD in T2DM. The ROC curve analysis showed that TyG had an area under the ROC curve (AUC) of 0.875 in predicting NAFLD in T2DM, with a sensitivity of 80.3%, a specificity of 80.1%, a positive predictive value of 86.36%, and a negative predictive value of 72.19% at the optimal cut-off value of 9.41; BMI had an AUC of 0.787, with a sensitivity of 78.9%, a specificity of 64.0%, a positive predictive value of 77.36%, and a negative predictive value of 64.23% at the optimal cut-off value of 24.22; TyG combined with BMI had an AUC of 0.910, a sensitivity of 81.2%, a specificity of 88.2%, a positive predictive value of 91.53%, and a negative predictive value of 75.00% in predicting NAFLD in T2DM. TyG alone, BMI alone, and TyG combined with BMI had a Kappa coefficient of 0.592, 0.416, and 0.673, respectively, in predicting NAFLD in T2DM. Conclusion TyG and BMI can be used to predict the onset of NAFLD in T2DM, and the combination of TyG and BMI can improve the predictive value.

Objective To investigate the expression of Smad4 in gastric carcinoma and its relationship with clinicopathological characteristics. Methods Immunohistochemistry method was used to detect the expression of Smad4 in 85 gastric carcinoma tissue and 36 normal gastric mucosa from January 2014 to December 2016. Results (1)The positive expression rate of Smad4 in gastric carcinoma tissues was 35. 29% (30/ 85), which was significantly lower than that in normal gastric mucosa (91. 67% (33/ 36)),and the difference was statistically significant (χ2=32. 201,P<0. 001). (2) The expression of Smad4 was correlated with the depth ofinvasion(χ2=13. 626,P<0. 001),lymph nodes metastasis(χ2=7. 267,P=0. 007),TNM staging(χ2=18. 226,P<0. 001) and tumor differentiation level (χ2 = 9. 134, P= 0. 010) . ( 3) Multivariate unconditional logistic regression analysis showed that depth of invasion(OR=7. 892,95CI 1. 649-37. 790,P=0. 010),TNM staging ( OR=15. 042, 95CI 0. 026-0. 977, P=0. 005 ) and tumor differentiation level ( OR=15. 042, 95CI2. 292-98. 751, P = 0. 005 ) may be independent influencing factors for Smad4 expression in gastric carcinoma. Conclusion Smad4 may performed an important role during the progression of gastric carcinoma and may be a new biological marker of gastric carcinoma.

Inflammatory bowel disease(IBD),including ulcerative colitis and Crohn's disease,was often associated with malnutrition in the course of disease development. Enteral nutrition ( EN ) can improve the nutritional status of IBD patients, relieve the illness, and promote the recovery of the disease. Therefore, we should pay attention to the significance of EN in the IBD treatment,and strengthen the implementation of EN in IBD patients.

Objective To investigate the clinical characteristics and prognosis of primary diffuse large B-cell lymphoma of central nervous system ( PCNS DLBCL). Methods The data of 70 patients with PCNS DLBCL confirmed by pathology were retrospectively analyzed. Survival and prognostic analyses were further conducted in the 66 follow-up patients. Results Median age at diagnosis was 57 years old. The ratio of male and female was 1.3∶1. The time from having symptoms to seeking medical advice was less than 2 months in 54 (77.1%) patients. 44 (62.9 %) patients had increased intracranial pressure, and 26 (37.1 %) patients had limb weakness or hemiplegia symptoms. 37 (52.9%) patients were multiple lesions, 59 (84.3%) cases were supratentorial, and 46 (65.7%) cases showed involvement of deep-brain tissues. Among 66 follow-up patients 7 cases received supportive and palliative care, 27 cases received surgery, 6 cases received radiotherapy, 9 cases received chemotherapy alone, and 21 cases received radiotherapy in addition to chemotherapy. The median overall survival (OS) was 9 months (95 % CI 1-16 months), and the 2-year survival rate was 36.1 %. The median OSs of the supportive and palliative therapy group and the surgery group were 2 months and 3 months, respectively. The median OS of the chemotherapy, radiotherapy or combination group was 33 months (95%CI 22-43 months) and the 2-year OS rate was 56.9 %. The Cox multivariate regression analysis showed that the involvement of deep-brain tissues (P=0.04) and not receiving radiotherapy or chemotherapy (P=0.00) were related to poor prognosis. Conclusions PCNS DLBCL is a highly aggressive and malignant tumor. Patients undergoing only surgery have poor effect and short survival. The patients with involvement of deep brain tissues have a poor prognosis. The chemotherapy, radiotherapy or combination of them may improve the prognosis.
