目的:检测血清雌二醇(E2)的水平,在一定程度上了解女性生育能力及身体健康状况。探讨各种致病因子对人体的损害。方法:放射免疫全定量分析,统计学上采用百分比统计。结果:笔者对近三年1164例有生殖系统临床症状(主要表现为月经不调、量少或停经等),年龄在18岁至40岁间的育龄女性患者的雌二醇－E2检测结果进行了回顾性总结分析,发现其激素水平呈逐年下降趋势,年龄也趋向相对低龄趋势。结论:上述结果可能在一定程度上反映了生活环境、工作环境、生活习惯、食物、药物及其他疾病等因数都会对人体内分泌及生殖系统的生理健康造成一定程度的影响甚至产生严重疾患。
ObjectiveTo set reference intervals of the levels of thyroid hormones among normal pregnant women without presence of thyroid antibodies during three trimesters of pregnancy in Quanzhou city, Fujian province. MethodsA total of 490 pregnant women during 4-39 week pregnancy without presence of thyroid antibodies were enrolled in Quanzhou city, Fujian province. Levels of thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4) and thyroid peroxidase antibodies (TPO-Ab) were detected through the electrochemistry immunoassay (ECL) method. In addition, a total of 51 healthy women without pregnancy were enrolled to set the reference intervals of levels of thyroid hormones among normal pregnant women without presence of thyroid antibodies. ResultsThe median levels of TPO-Ab were in the reference intervals provided by the pharmaceutical factory. Levels of FT3 and FT4 gradually decreased from the first to the third trimester (P < 0.01), levels of serum TSH gradually increasd from the first to the third trimester (P < 0.01). Compared with those of pregnant women, levels of thyroid hormone in normal non-pregnant women were higher in the first trimester, lower in the second and the third trimesters (P < 0.01). During three trimesters, the reference intervals of FT3 in the three trimesters were (first: 3.75 to 7.23; second 3.31 to 4.9; and third: 3.16 to 4.48 pmol/L); the reference intervals of FT4 were (first: 12.85 to 25.3; second: 12.03 to 20.14; and third: 11.02 to 19.43 pmol/L); and the reference intervals of TSH were (first: 0.01 to 3.79; second: 1.09 to 4.19; and third: 1.08 to 5.95 mIU/L), respectively. ConclusionThrough this detection, we set the levels of thyroid hormones among normal pregnant women without presence of thyroid antibodies during three trimesters of pregnancy in Quanzhou city.
ObjectiveTo establish a normal reference value range of specific thyroid function in pregnant women corresponding to Beckman reagent in Chengdu.MethodsWe randomly selected 120 non-pregnant women and 445 pregnant women who underwent routine examinations at the First Affiliated Hospital of Chengdu Medical College from November 2016 to June 2017; tested for free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) in serum; used SPSS 24.0 to calculate the bilateral limit of each index (Section 2.5, 97. 5 Quot); established the normal range of Beckman reagent.ResultsThe reference ranges of FT3, FT4, and TSH in the first, second, and third trimester of pregnancy were 4.41–6.33, 4.17–6.12, and 3.86–6.39 pmol/L; 7.64–14.63, 6.62–13.69, and 6.62–12.51 pmol/L; 0.21–3.62, 0.16–4.35, and 0.89–4.88 mU/L; respectively. There was no significant difference in serum TSH between the first and second trimester (P>0.05), and neither between the first and second trimesters and the controls in serum FT3 (P>0.05). The differences in serum FT3, FT4, and TSH among the rest of trimesters, and between each trimester and the normal control group were statistically significant (P<0.05). There was a significant correlation between TSH and FT4 in the early and middle stages of pregnancy (r=–0.277, –0.392, P<0.01).ConclusionThe reference value of FT3, FT4, and TSH in pregnant women with Beckman reagent was significantly different from that in non-pregnant women.
