目的分析2型糖尿病合并甲状腺功能亢进(以下简称甲亢)患者血清信号素5A(Sema 5A)、胰岛素样生长因子结合蛋白-3(IGFBP-3)水平与糖代谢指标的相关性。方法选取2021年6月至2022年6月邯郸市中心医院收治的73例2型糖尿病合并甲亢患者作为合并组,56例单纯2型糖尿病患者作为糖尿病组,另选取同期在邯郸市中心医院体检的68例健康者作为对照组。比较对照组、糖尿病组、合并组血清Sema 5A、IGFBP-3水平,比较糖尿病组、合并组临床资料[体质量指数、糖尿病病程、空腹血糖(FBG)、餐后2 h血糖(2 h PG)、胰岛素(FIN)、甘油三酯、总胆固醇、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、糖化血红蛋白(HbA1c)、三碘甲腺原氨酸(T_(3))、甲状腺素(T_(4))、游离三碘甲腺原氨酸(FT_(3))、游离甲状腺素(FT_(4))、促甲状腺素(TSH)、促甲状腺激素受体抗体(TRAB)及甲状腺过氧化物酶抗体(TPOAB)、胰岛素抵抗指数(HOMA-IR)]。采用多因素Logisitic回归分析2型糖尿病并发甲亢的危险因素,采用Pearson相关分析2型糖尿病合并甲亢患者血清Sema 5A、IGFBP-3水平与糖代谢指标的相关性,绘制受试者工作特征(ROC)曲线分析血清Sema 5A、IGFBP-3对2型糖尿病合并甲亢的诊断价值。结果合并组血清Sema 5A、IGFBP-3水平高于对照组和糖尿病组,且糖尿病组高于对照组,差异均有统计学意义(P<0.05)。合并组糖尿病病程长于糖尿病组,血清HOMA-IR、FIN、HbA1c、T_(3)、T_(4)、FT_(3)、FT_(4)、TRAB、TPOAB水平高于糖尿病组,TSH水平低于糖尿病组,差异均有统计学意义(P<0.05)。多因素Logisitic回归分析结果显示,HOMA-IR、TPOAB、Sema 5A、IGFBP-3水平升高,TSH水平降低为2型糖尿病并发甲亢的危险因素(P<0.05)。Pearson相关分析结果显示,2型糖尿病并发甲亢患者血清Sema 5A、IGFBP-3水平与HOMA-IR、FBG、2 h PG、FIN、HbA1c、HDL-C水平均呈正相关(P<0.05)。2型糖尿病并发甲亢患者血清Sema 5A、IGFBP-3水平与LDL-C水平呈负相关(P<0.05)。ROC曲线分析结果显示,血清Sema 5A、IGFBP-3诊断2型糖尿病合并甲亢的曲线下面积(AUC)分别为0.854、0.804,2项指标联合诊断的AUC为0.900,且2项指标联合诊断的AUC高于Sema 5A、IGFBP-3单独诊断的AUC(Z联合-Sema 5A=2.156,P=0.043;Z联合-IGFBP-3=2.873,P=0.004)。结论2型糖尿病合并甲亢患者血清Sema 5A、IGFBP-3水平升高,且二者与糖代谢指标密切相关。

目的:探讨丹参酮ⅡA(TanⅡA)对糖尿病雄性大鼠生殖损伤的影响及其机制。方法:随机选取43只雄性SD大鼠中的35只通过高糖高脂喂养联合腹腔注射链脲佐菌素构建糖尿病动物模型,并分为模型组、TanⅡA(6 mg/kg)组、SB203580[p38丝裂原活化蛋白激酶(p38MAPK)抑制剂,2 mg/kg]组和TanⅡA+SB203580(6 mg/kg+2 mg/kg)组,每组8只;剩余8只设为正常组。给药治疗4周后,检测空腹血糖(FBG)水平。ELISA法检测血清睾酮(T)、黄体生成素(LH)、卵泡刺激素(FSH)含量。检测精子质量(浓度、存活率和活力),测量睾丸重量并计算睾丸指数。HE染色法观察睾丸组织病理学改变。检测睾丸组织总超氧化物歧化酶(T-SOD)、过氧化氢酶(CAT)活力和丙二醛(MDA)、肿瘤坏死因子-α(TNF-α)、白细胞介素-1β(IL-1β)、IL-8含量。Western blot法检测睾丸组织p38MAPK、p-p38MAPK、核因子-κB p65(NF-κB p65)、p-NF-κB p65、高迁移率族蛋白B1(HMGB1)表达。结果:与模型组比较,TanⅡA组、SB203580组和TanⅡA+SB203580组FBG水平比较差异无统计学意义(均P>0.05);T、LH、FSH含量和精子浓度、存活率及活力升高(均P<0.05);睾丸重量和睾丸指数升高(均P<0.05);睾丸组织病理学改变明显改善;T-SOD、CAT活力升高且MDA、TNF-α、IL-1β、IL-8含量降低(均P<0.05);HMGB1水平和p-p38MAPK/p38MAPK、p-NF-κB p65/NF-κB p65比值降低(均P<0.05)。TanⅡA+SB203580组以上指标优于TanⅡA组和SB203580组(均P<0.05)。结论:TanⅡA可能通过抑制p38MAPK/NF-κB信号通路,降低氧化应激水平和炎症反应,从而减轻糖尿病雄性大鼠生殖损伤。

中国这条东方巨龙已经苏醒,中国的国际地位逐日高升。中国的文化在世界各地传播,遍"球"开花。孔子学院已遍布134个国家,已有五百多所孔子学院和一千多孔子课堂,由此可以看出中国文化的热度,也可以感知到学习汉语的世界各地的朋友如此热情。而且每年有大批来自世界各地的留学生到中国各高校学习汉语,再掀"汉语热"高潮。但是留学生数目的增加,学习汉语狂潮的掀起,让我们也看到了对外汉语教学中语音教学存在的一些问题。本文就针对这些问题提出了相应的举措。
