高碘对小鼠脑发育及血清游离甲状腺激素水平的影响

】为了解高碘对机体脑发育及代谢的影响，本实验用高碘水喂养小鼠复制出高碘甲状腺肿动物模型。结果发现，用高碘水喂养小鼠２１０天后，高碘组小鼠体重减轻，甲状腺重量明显增加，血清ＦＴ３及ＦＴ４水平均显著高于适碘组。两组比较脑重、脑ＤＮＡ、蛋白质含量均无显著差异。揭示高碘不影响脑发育但可使代谢率增加。

聊城市妊娠妇女甲状腺激素参考区间的建立

目的：建立本实验室妊娠妇女促甲状腺激素（TSH）、游离甲状腺素（FT4）和游离三碘甲状腺原氨酸（FT3）的参考区间。方法：将826例妊娠妇女分为妊娠早中晚期3组，用Beckman access2化学发光分析仪及其配套试剂检测TSH、FT4、FT3，初步建立参考区间。结果：TSH参考区间：妊娠早期0.11～2.88 uIU/ml，妊娠中期0.24～3.31 uIU/ml，妊娠晚期0.55～3.78 uIU/ml。FT4参考区间：妊娠早期0.69～1.13 ng/dl，妊娠中期0.56～0.99 ng/dl，妊娠晚期0.49～0.89 ng/dl。FT3参考区间：妊娠早期2.67～4.03 pg/ml，妊娠中期2.35～3.56 pg/ml，妊娠晚期2.08～3.25 pg/ml。结论：建立了本院妊娠妇女血清TSH、FT4、FT3的参考区间，该区间与Beckman access2化学发光分析仪说明书提供的参考区间有差异。各实验室应根据不同仪器和人群等建立TSH、FT4、FT3的参考区间。

The Reproductive and Thyroid Hormonal Profile of Khat (Catha Edulis) Chewers

The effects of khat on the hormonal levels have been established;however, the effects on human beings are controversial. The aim of our study was to investigate the possible effects of khat on the levels of serum thyroid hormones, testosterone, estradiol (E2), prolactin and cortisol in men. A total of 50 blood samples were collected from healthy males who referred to chew khat for more than 10 years and analyzed for the above hormones. The results were compared to the hormonal levels of 35 non khat chewers. Chewing khat causes significant increases in the testosterone (P < 0.03), prolactin (P < 0.05), E2 (P < 0.00005), FT3 (P < 0.04), and TSH (P < 0.05) levels. No significant differences were found in the serum level of FT4 between the two groups. The level of cortisol were significantly lower (P < 0.001) in the khat chewers group compared to the control group. This study suggests that khat chewing can cause reduction in the cortisol level, which may cause increases of testosterone, prolactin and E2. In addition, chewing khat increases the level of TSH and FT3 serum levels. Therefore, khat may contribute to the relevant disorders caused by abnormal levels of the studied hormones in the people who are chewing

空腹血糖受损者游离三碘甲状腺原氨酸与血脂代谢关系的研究

目的探讨空腹血糖受损者甲状腺功能对血脂代谢的影响。方法选取在我院体检的空腹血糖受损者438例为空腹血糖受损组(IFG组),另选取健康体检者135例作为对照组(NC组)。分析两组各项体检指标及IFG组患者指标与LDL-C的关系。结果 IFG组患者的TG、TC、BMI、LDL-C、FBG水平均高于NC组,HDL-C和FT3水平低于NC组(P<0.01)。IFG组LDL-C与BMI和FBG呈正相关,与FT3呈负相关(r=0.2592,2.8863,-1.1316,P<0.01)。多元线性回归分析结果显示,BMI和FT3是LDL-C的影响因素。结论随着血糖升高,空腹血糖受损者血脂代谢紊乱加重,FT3水平下降。FT3是影响空腹血糖受损者血脂变化的重要因素。

2型糖尿病患者游离三碘甲状腺原氨酸与血脂代谢关系的研究

目的评估不同血糖控制情况下T2DM患者甲状腺功能对血脂代谢的影响。方法选取住院T2DM患者595例,根据HbA1c水平分为HbA1c<7.0%组108例、7.0%≤HbA1c<9.0%组164例及HbA1c≥9.0%组323例,另选取健康体检者61名作为对照(NC)组。对各组指标进行比较,明确T2DM患者甲状腺功能指标与非高密度脂蛋白胆固醇(non-HDL-C)的关系。结果 HbA1c≥9.0%组non-HDL-C水平高于HbA1c<7.0%组、7.0%≤HbA1c<9.0%组和NC组[(3.84±1.16)vs(3.32±1.07),(3.59±0.96),(3.21±0.77)mmol/L,P均<0.05]。HbA1c≥9.0%组游离三碘甲状腺原氨酸(FT3)水平低于HbA1c<7.0%组、7.0%≤HbA1c<9.0%组和NC组[(2.43±0.50)vs(2.69±0.46),(2.66±0.45),(2.91±0.44)pg/ml,P均<0.05]。T2DM患者non-HDL-C与BMI、FPG和HbA1c呈正相关,与FT3呈负相关。多元线性回归分析提示,BMI、HbA1c和FT3是non-HDL-C的影响因素。结论随血糖升高,T2DM患者血脂代谢紊乱加重,FT3水平下降;FT3是影响T2DM患者血脂变化的重要因素。
