Metabolic dysfunction-associated fatty liver disease （MAFLD） is a common chronic liver disease with the pathological feature of lipid accumulation in the liver， and it is closely associated with liver metabolic disorders. The latest research has shown that the pathogenesis of MAFLD is associated with the abnormal expression of specific genes， especially the fat mass and obesity-associated （FTO） gene. The abnormal activity of the FTO gene may lead to an imbalance in liver lipid metabolism， which manifests as the increase in fatty acid synthesis and the reduction in fatty acid oxidation， thereby promoting liver fat deposition and inflammatory response. Therefore， regulating the expression or activity of the FTO gene is considered one of the potential strategies for the treatment of MAFLD. At present， drug research targeting the function of the FTO gene has achieved preliminary results， and inhibition of the activity of the FTO gene can help to regulate liver lipid metabolism and alleviate liver inflammatory injury. This article reviews the mechanism of action of the FTO gene in the development and progression of MAFLD， summarizes the advances in drug research on the FTO gene and related metabolic pathways in recent years， and analyzes their application prospect in research and treatment.

OBJECTIVE To study the mechanism of Compound lizard powder on reversing cisplatin（DDP） resistance in resistant gastric cancer cell MKN45/DDP through nuclear factor-κB （NF-κB）/SNAIL signaling pathway. METHODS MKN45/DDP cells were divided into model group （20% normal rat serum）， DDP group （1.3 μg/mL DDP+20% fetal bovine serum） and Compound lizard powder low- and high-dose drug-containing serum+DDP groups （17.2， 68.8 g/kg Compound lizard powder 20% drug-containing serum+1.3 μg/mL DDP）. The viability， apoptosis and intracellular autophagosome of MKN45/DDP cells were detected. The content of microtubule-associated protein 1 light chain 3 （LC3） in the cell supernatant was detected. The expressions of B-cell lymphoma 2 （Bcl-2）， Bcl-2-related X protein （Bax）， as well as the protein expression levels of phosphorylated NF-κB p65 （p-NF-κB p65） and SNAIL were detected. The molecular mechanism of Compound lizard powder in improving DDP resistance was further clarified by using NF-κB pathway agonist tumor necrosis factor-α （TNF-α）. RESULTS Compared with model group and DDP group， the cell survival rates of Compound lizard powder low- and high-dose drug-containing serum+DDP groups were significantly decreased （P＜0.05）， while the levels of apoptosis and autophagic death were significantly increased （P＜0.05）. The expression levels of Bcl-2 （except for the compound lizard powder low-dose drug-containing serum+DDP group）， p-NF-κB p65 and SNAIL protein in MKN45/DDP cells were significantly decreased （P＜0.05）. The content of LC3 and expression of Bax protein were significantly increased （P＜0.05）. High-dose Compound lizard powder drug-containing serum+DDP could effectively reverse the down-regulation of LC3 Ⅱ/LC3 Ⅰ and Bax protein expression induced by TNF- α （P＜0.05）. CONCLUSIONS Compound lizard powder drug-containing serum combined with DDP can induce apoptosis and autophagic death of MKN45/DDP cells by inhibiting NF-κB/SNAIL signaling pathway， thus reversing DDP resistance of cells.

Objective:To explore the causal association between insulin-like growth factor-1(IGF-1)and colorectal cancer(CRC)based on two sample Mendelian randomization(MR)analysis.Methods:A bidirectional two sample MR analysis was conducted based on publicly aggregated data from the IEU OpenGWAS project.The inverse variance weighted(IVW)method was used as the main analysis model to assess the causal relationship between IGF-1 and CRC.Additional analyses were performed using weighted median(WM),MR-Egger regression,weighted mode estimator(WME),and simple mode(SM)methods.Sensitivity analysis was performed to assess the robustness of the results.Results:A total of 386 single nucleotide polymorphisms(SNPs)were selected as instrumental variables(IVs)with IGF-1 as the exposure factor.The MR analysis results revealed a positive causal association between IGF-1 and the risk of CRC[odds ratio(OR)=1.178,95％confidence interval(CI):1.092-1.272)](P＜0.001),and the association remained significant after adjusting for height[OR(95％CI)=1.214(1.111,1.327)](P＜0.001).Cochran's Q-test showed heterogeneity among the IVs(P＜0.05),while the horizontal pleiotropy of IV was not detected by the MR-Egger regression(P＞0.05).The leave-one-out analysis showed that the MR results were robust.Reverse MR analysis indicated no reverse causal relationship between IGF-1 and CRC[OR(95％CI):1.017(0.997,1.037)](P=0.103).Conclusion:There is a causal relationship between IGF-1 level and CRC,and elevated IGF-1 level could be a risk factor for CRC.

Objective:To explore the predictive value of the combined application of total prostate-specific antigen (TPSA), vascular endothelial growth factor A (VEGF-A), and interleukin (IL) in predicting postoperative biochemical recurrence in patients with prostate cancer.Methods:This study adopted a retrospective cohort research method. 202 male prostate cancer patients who visited Xi′an Gaoxin Hospital from April 2021 to January 2024 were selected as the research subjects. The age of the patients was 68(64, 71) years, and their postoperative conditions were classified into the non-recurrence group ( n=144) and the biochemical recurrence group ( n=58). The general clinical data and serumological test indicators SA, free prostate-specific antigen (FPSA), VEGF-A, IL-6, IL-17] were detected and compared between the two groups. Quantitative data with normal distribution were expressed as mean±standard deviation, and the comparison between groups was performed using the independent sample t-test; non-normal distribution quantitative data were expressed as M( Q1, Q3), and the comparison between groups was performed using the Mann-Whitney U test. The comparison between groups of count data was performed using the chi-square test. Through Spearman correlation analysis and multivariate Logistic regression analysis, the risk factors for biochemical recurrence after surgery in prostate cancer patients were screened out, and the efficacy of the combined prediction model based on TPSA, VEGF-A, and IL-17 was evaluated by receiver operating characteristic (ROC) curve, decision curve (DCA), and calibration curve. Results:The average tumor diameter, proportion of positive surgical margins, proportion of seminal vesicle invasion, and proportion of patients with Gleason score 3-5 in the biochemical recurrence group were significantly higher than those in the non-recurrence group ( P<0.05). The serumological indicators TPSA, VEGF-A, IL-6, IL-17 in the biochemical recurrence group were 44.28 (42.37, 48.57) ng/mL, (28.24±3.99) ng/mL, (39.14±2.95) ng/L and (66.64±6.04) pg/mL; those in the non-recurrence group were 41.25 (36.61, 43.56) ng/mL, (23.52±3.75) ng/mL, (37.19±4.19) ng/L, and (57.31±6.63) pg/mL. The biochemical recurrence group was higher than the non-recurrence group, and the difference was statistically significant ( P<0.05). Spearman correlation analysis and Logistic regression analysis found that TPSA, VEGF-A, and IL-17 were risk factors for biochemical recurrence after surgery in prostate cancer patients ( P<0.05); the DCA curve and calibration curve indicated that the combined prediction model based on TPSA, VEGF-A, and IL-17 had good accuracy (Hosmer-Lemeshow P=0.421), and the ROC curve suggested that the efficacy of the above indicators combined for predicting biochemical recurrence after surgery in prostate cancer patients was higher [AUC (95% CI)=0.899 (0.832-0.966)], and higher than the independent predictive efficacy of each indicator. Conclusion:Continuous monitoring of serum TPSA, VEGF-A, and IL-17 levels can effectively predict the risk of postoperative recurrence in prostate cancer patients and also provide biological markers for preventing disease recurrence.

OBJECTIVE To explore the mechanism of Compound lizard powder reducing cisplatin resistance in gastric cancer by regulating glycolytic activity based on phosphoinositide 3-kinase（PI3K）/protein kinase B（Akt） signaling pathway. METHODS Human gastric cancer MKN45 and MKN45/DDP （cisplatin-resistant） cells were cultured in vitro and intervened with different mass concentrations of cisplatin （0.1， 0.2， 0.4， 0.8， 1.6， 3.2 μg/mL） to detect the survival rate， half inhibitory concentration （IC50） and drug resistance index. MKN45/DDP cells were inoculated subcutaneously in the right anterior axilla of nude mice to prepare a transplanted tumor model of gastric cancer. After successful modeling， they were randomly divided into model group， cisplatin group （0.002 g/kg）， Compound lizard powder group （2.8 g/kg） and combination group （the same dose as each single drug group）， with 8 nude mice in each group. Each administration group was given relevant solution， twice a week （cisplatin， i.p.） or twice a day （Compound lizard powder， i. g.）， for 4 consecutive weeks. During the experiment， the body weight of nude mice was monitored， and tumor volume and inhibitory rate of tumor were calculated. The levels of inflammatory factors （tumor necrosis factor- α， interleukin-6） in tumor tissue， the mRNA and protein expressions of multidrug resistance-associated protein 1 （MRP1）， P-glycoprotein （P-gp）， glucose transporter-1 （GLUT1） and lactate dehydrogenase A （LDHA）， as well as the protein expressions of PI3K， phosphorylated PI3K （p-PI3K）， Akt， phosphorylated Akt （p-Akt）， hexokinase-2 （HK2） and pyruvate kinase M2 （PKM2） were all detected. RESULTS With the intervention of different concentrations of cisplatin， the survival rate of MKN45/DDP-resistant cells was significantly higher than that of MKN45 parent cells （P＜0.05）. IC50 value of MKN45/DDP and MKN45 cells were（1.052 0±0.221 9） and （0.372 1±0.238 0）μg/mL， and the drug resistant index was 2.827. Compared with the model group， cisplatin group， Compound lizard powder group and combination group all had certain inhibitory effects on the tumor growth in nude mice； the inhibitory rates of tumor increased significantly （P＜0.05）； the levels of inflammatory factors， the mRNA and protein expressions of MRP1， P-gp， GLUT1 and LDHA （except for cisplatin group）， the phosphorylation levels of PI3K and Akt protein （except for cisplatin group） as well as the protein expressions of HK2 and PKM2 were decreased significantly， while the combination group was significantly better than the cisplatin group （P＜0.05）. CONCLUSIONS Compound lizard powder may inhibit tumor growth in transplanted tumor model nude mice with gastric cancer-resistant cells by reducing the secretion of tumor-related inflammatory factors， inhibiting the expression of glycolysis， drug resistance-related proteins and genes， inhibiting the activation of the PI3K/Akt signaling pathway， thus having a certain effect of enhancing cisplatin efficacy and reversing drug resistance.

Objective To explore the value of preoperative detection of soluble fragments of cytokeratin-19 (CYFRA21-1), carcinoembryonic antigen (CEA), and postoperative detection of nuclear proliferation associated antigen Ki67 in prognostic evaluation of non-small cell lung cancer patients. Methods The clinicopathological data and follow-up results of patients with non-small cell lung cancer treated in the Department of Thoracic Surgery of the First Affiliated Hospital of Xiamen University in 2017 were collected. CYFRA21-1>3.39 ng/mL was defined as positive, and CEA>5 ng/mL was defined as positive. The receiver operating characteristic curve (ROC curve) of Ki67 expression level was drawn. The maximum area under the curve (AUC) was the cutoff value of Ki67 expression level, and the Ki67 expression level greater than its cutoff value was defined as positive. Cox regression analysis was used to determine the independent risk factors for poor prognosis in patients with non-small cell lung cancer. Results Finally 248 patients were collected, including 125 males and 123 females, with a median age of 61 years (ranging from 30 to 81 years) at the time of surgery. Univariate analysis showed that positive CYFRA21-1, high expression of Ki67, positive CEA, age≥60 years at operation, distant metastasis, lymph node metastasis, maximum tumor diameter>3 cm, and TNM stage Ⅲ were associated with poor prognosis in patients with non-small cell lung cancer. When combined detection of preoperative tumor markers and postoperative Ki67, the prognosis of all negative patients was the best, and that of all positive patients was the worst. Cox regression analysis showed that positive CEA+positive CYFRA21-1+high expression of Ki67 was an independent risk factor for poor prognosis in patients with non-small cell lung cancer (P<0.05). Conclusion The combined detection of preoperative serum CYFRA21-1, CEA, and postoperative Ki67 has important value in evaluating the prognosis of non-small cell lung cancer patients.

Objective:To evaluate the value of the ratio of tricuspid annular plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP) in evaluating right ventricular function of patients with hypertrophic cardiomyopathy (HCM) and heart failure with preserved ejection fraction (HFpEF).Methods:A total of 74 patients with HCM and HFpEF and 22 healthy individuals who visited the First Affiliated Hospital of Zhengzhou University from January 2021 to January 2023 were included in this study. The HCM patients with HFpEF were divided into three groups based on the tertiles of the TAPSE/PASP (low group: <0.280 0 mm/mmHg; middle group: 0.280 0-0.476 2 mm/mmHg; high group: >0.476 2 mm/mmHg). Conventional echocardiographic parameters were collected, and two-dimensional speckle tracking technology was used to obtain right ventricular strain parameters. The differences in parameters among the groups were compared, and the correlations between TAPSE/PASP and clinical parameters and right ventricular function parameters were analyzed.Results:The results of difference analysis showed that there were significant differences in 6-minute walking test, New York Heart Association grade (NYHA grade), incidence of atrial fibrillation, left atrial area (LAA), left ventricular global longitudinal strain (LVGLS), TAPSE, PASP, right ventricular fractional area change (RVFAC), right ventricular global longitudinal strain (RVGLS), right ventricular free wall strain (RVFWST) and cardiac magnetic resonance right ventricular ejection fraction (CMR-RVEF) among the three groups. The results of correlation analysis and multiple linear regression analysis showed that the TAPSE/PASP was positively correlated with 6-minute walking distance, RVFAC, tricuspid annulus peak systolic velocity (RV s′), and CMR-RVEF ( r=0.449, 0.284, 0.358, 0.577; all P<0.05). It was negatively correlated with N-terminal pro-brain natriuretic peptide (NT-proBNP), NYHA grade, LAA, mitral early diastolic peak velocity / mitral annulus early diastolic peak velocity (LV E/e′), LVGLS, RVGLS, RVFWST and tricuspid early diastolic peak velocity / tricuspid annulus early diastolic peak velocity (RV E/e′) (r/ rs=-0.336, -0.349, -0.468, -0.452, -0.444, -0.339, -0.405, -0.320; all P<0.05). The LAA and CMR-RVEF correlated independently with TAPSE/PASP(all P<0.05). Conclusions:The TAPSE/PASP can provide an early, simple, rapid, and convenient evaluation of right ventricular function in patients with HCM and HFpEF, so as to guide clinical treatment and monitoring disease progression.
