Objective To explore the mechanism of competitive binding of non coding long stranded RNA ANRIL（lncRNA-ANRIL）to miR-181b to mediate phosphatase and tensin homolog gene（PTEN）on myocardial injury in coronary heart disease．Methods Thirty patients diagnosed with coronary heart disease in our hospital from October 2023 to June 2024 were included as the observation group,and another 30 individuals from physical examination center during the same period were selected as the control group．Blood pressure indicators,blood lipid indicators, and serum levels of lncRNA-ANRIL, miR-181b, and PTEN were measured in the two groups of patients, and the test results were compared．Results There was no significant difference between the two groups in terms of gender, age, BMI, smoking and hypertension（P>0.05）．The levels of systolic blood pressure（SBP）, diastolic blood pressure（DBP）, total cholesterol（TC）, triglycerides（TG）, and low-density lipoprotein cholesterol（LDL-C） in the observation group were higher than those in the control group,while high-density lipoprotein cholesterol（HDL-C） was lower than that in the control group（P<0.05）．The relative expression levels of lncRNA-ANRIL Exon 1-2, Exon 17-18, and PTEN levels in the observation group were lower than those in the control group（t=12.623, 7.741, 8.231, P=0.001）, while the level of miR-181b was higher than that in the control group（t=37.250, P=0.001）．Conclusions Compared with healthy individuals, serum levels of lncRNA-ANRIL and PTEN are significantly reduced in patients with coronary heart disease, while miR-181b levels are elevated, indicating that lncRNA ANRIL can regulate PTEN expression by miR-181b, thereby affecting the process of myocardial injury in coronary heart disease．
目的 观察辅助性T17细胞（Th17）与调节性T细胞（Treg）比值与2型糖尿病（T2DM）患者胰岛素抵抗及胰岛β细胞功能的关系。方法 纳入2022年4月—2023年4月在贵州医科大学第二附属医院内分泌科住院及健康体检人群各100例, 分为糖耐量正常组（NGT组, n=100）和T2DM组（n=100）, 分别测定糖化血红蛋白（HbA1c）、空腹血糖（FPG）、甘油三酯（TG）等生化指标, 电化学发光法测定空腹胰岛素（FINS）, 稳态模型计算胰岛β细胞功能指数（HOMA-β）、胰岛素抵抗指数（HOMA-IR）及胰岛素敏感指数（HOMA-ISI）。流式细胞术检测Th17、Treg水平。HOMA-IR、HOMA-β和HOMA-ISI的影响因素采用多元线性回归分析。结果 与NGT组相比, T2DM组BMI、FPG、HbA1c、LDL-C 、TG、TC、FINS、HOMA-IR、Th17及Th17/Treg水平均升高（P<0.01）, HDL-C、HOMA-β、HOMA-ISI、Treg水平均降低, 且差异有统计学意义（P<0.01）。Th17与BMI（r=0.251, P<0.001）及HOMA-IR（r=0.305, P<0.001）呈正相关; 与HOMA-β（r=-0.204, P<0.001）及HOMA-ISI（r=-0.359, P<0.001）呈负相关。Treg与HOMA-ISI之间呈正相关（r=0.170, P=0.008）, 而与HOMA-IR呈负相关（r=-0.153, P=0.017）; Th17/Treg与BMI（r=0.332, P<0.001）及HOMA-IR（r=0.374, P<0.001）;与HOMA-β（r=-0.249, P<0.001）及HOMA-ISI（r=-0.427, P<0.001）呈负相关。多元线性回归分析显示, Th17/Treg是HOMA-IR（β=5.915）升高及HOMA-ISI（β=-2.557）下降的影响因素（P<0.01）。结论 Th17/Treg可能通过影响胰岛素抵抗、降低胰岛素敏感性参与T2DM的发生。
Objective To explore the relationship among the proportion of helper T17 cells（Th17）to regulatory T cells（Treg）, insulin resistance, and the function of islet beta cells．Methods One hundred cases of hospitalized patients and 100 cases of health check-ups people in the Department of Endocrinology of the Second Affiliated Hospital of Guizhou Medical University from April 2022 to April 2023 were included．Patients were divided into normal glucose tolerance group（NGT group, n=100）and type 2 diabetes mellitus group（T2DM group, n=100）．The biochemical indexes of HbA1c, fasting blood glucose（FPG）, triglyceride（TG）and fasting insulin（FINS）were determined by electrochemiluminescence．Islet beta cell function index（HOMA-β）, insulin resistance index（HOMA-IR）and insulin sensitivity index（HOMA-ISI）were calculated in homeostasis model．The levels of Th17 and Treg were detected by flow cytometry．Spearman was used to analyze the correlation between indicators, and multiple linear regression analysis was used to analyze the influencing factors of HOMA-IR, HOMA-β and HOMA-ISI．Results In contrast to the NGT group, the T2DM group exhibited elevated levels of BMI, FPG, HbA1c, LDL-C, TG, TC, FINS, HOMA-IR, Th17 and Th17/Treg, with these variances being signifincantly different（P<0.01）．There was a notable reduction in the levels of HDL-C,HOMA-β,HOMA-ISI,Treg,with those changes being significantly different（P<0.01）．Th17 was positively correlated with BMI（r=0.251, P<0.001）and HOMA-IR（r=0.305, P<0.001）, it was negatively correlated with HOMA-β（r=-0.204, P<0.001）and HOMA-ISI（r=-0.359, P<0.001）．Treg was positively correlated with HOMA-ISI（r=0.170, P=0.008）, while it was negatively correlated with HOMA-IR（r=-0.153, P=0.017）．The ratio of Th17/Treg was positively correlated with BMI（r=0.332, P<0.001）and HOMA-IR（r=0.374, P<0.001）, it was negatively correlated with HOMA-β（r=-0.249, P<0.001）and HOMA-ISI（r=-0.427, P<0.001）．Multiple linear regression analysis showed that Th17/Treg was an influential factor in the increase of HOMA-IR（β=5.915）and the decrease of HOMA-ISI（β=-2.557）（P<0.01）．Conclusions Th17/Treg may be involved in the development of T2DM by affecting insulin resistance and reducing insulin sensitivity．
目的 探讨卵巢癌化学治疗（化疗）耐药与焦孔素E（GSDME）基因的甲基化是否有关, 以及地西他滨是否可以通过去甲基化使GSDME蛋白表达水平升高从而逆转卵巢癌化疗耐药。方法 顺铂逆浓度梯度构建SKOV-3卵巢癌耐顺铂细胞株（SKOV-3/DDP）; CCK8法检测耐药前后细胞株的半抑制浓度（IC50）; 实时荧光定量甲基化特异性PCR法检测两组细胞中GSDME基因的甲基化水平; Wetern Blot检测两组细胞中GSDME的表达水平。将耐药细胞株用不同质量浓度的地西他滨处理,重复上述实验, 检测地西他滨处理前后细胞的IC50、GSDME基因的甲基化水平及GSDME蛋白的表达程度。结果 与SKOV-3细胞相比, SKOV-3/DDP中GSDME基因的甲基化水平升高（P<0.01）, 同时GSDME蛋白的表达水平降低（P<0.001）; 随着地西他滨作用浓度的升高, 耐药细胞中GSDME基因的甲基化程度逐渐降低, 蛋白的表达水平逐渐升高, 细胞的IC50逐渐降低：在用0.5 μg/mL地西他滨处理耐药细胞后GSDME基因的甲基化水平虽然降低（P<0.01）, 但是此时蛋白的表达水平及耐药细胞的IC50均无明显改变（P>0.05）; 当地西他滨的浓度增加到1.0 μg/mL时蛋白的表达水平才明显升高（P<0.05）, 而此时细胞的IC50仍未见明显降低（P>0.05）; 待药物浓度达到1.5 μg/mL时, 细胞的IC50才表现出明显的下降趋势（P<0.05）。结论 GSDME的表达与卵巢癌的化疗耐药密切相关, GSDME的高甲基化水平致使其低表达可促进卵巢癌的化疗耐药。但地西他滨可以通过去甲基化使卵巢癌耐药细胞中GSDME的表达水平升高, 从而增加卵巢癌细胞对化疗药物的敏感性, 进而逆转卵巢癌化疗耐药。
Objective To explore whether drug resistance in ovarian cancer is associated with gasdermin E（GSDME） methylation, and to explore whether decitabine can reverse ovarian cancer chemoresistance by increasing GSDME protein expression levels through demethylation．Methods The cisplatin-resistant cell line（SKOV-3/DDP）was constructed by inverse concentration gradient of cisplatin．Semi-inhibitory concentration（IC50）of cell lines after drug resistance was detected using the CCK8 assay．Real-time fluorescence quantitative methylation-specific PCR was used to detect the methylation level of GSDME gene in the two groups of cells．Wetern Blot was used to detect the expression level of GSDME in the two groups of cells．Drug-resistant cell lines were treated with different concentrations of the demethylating drug decitabine．Experiments above were repeated to detect the methylation degree of IC50 and GSDME genes and the expression level of GSDME protein in drug-resistant cells before and after decitabine treatment．Results Compared with SKOV-3 cells, the methylation level of GSDME gene in SKOV-3/DDP was significantly increased（P<0.01）, while the expression level of GSDME protein was significantly decreased（P<0.001）．With the increase of decitabine concentration, the methylation degree of GSDME gene in drug-resistant cells was gradually decreased, the expression level of protein was gradually increased, and the IC50 of cells was gradually decreased：the methylation level of GSDME gene was decreased after 0.05 μg/mL decitabine treatment（P<0.01）, but there were no significant changes in protein expression level and IC50 of drug-resistant cells（P>0.05）．The protein expression level was significantly increased when the concentration of local citabine was increased to 0.10 μg/mL（P<0.05）, while the IC50 of the cells was not significantly decreased（P>0.05）．When the drug concentration reached 0.15 μg/mL, he IC50 of the cells showed a significant downward trend（P<0.05）．Conclusions The expression of GSDME is closely related to chemoresistance in ovarian cancer, and the low expression of GSDME due to its high methylation level can promote chemoresistance in ovarian cancer．However, decitabine can increase the expression level of GSDME in drug-resistant ovarian cancer cells through demethylation,thereby increasing the sensitivity of ovarian cancer cells to chemotherapeutic drugs, and then reversing the chemoresistance of ovarian cancer．
