分化型甲状腺癌患者停用甲状腺激素后血脂与甲状腺功能的相关性分析

目的研究分化型甲状腺癌患者停用甲状腺激素后血脂与甲状腺功能的相关性。方法选取2014年8月至2015年8月在该院实施手术治疗的130例分化型甲状腺癌患者,患者在停止应用左甲状腺激素钠(L-T4)前、手术前以及停药3周后分别测定血清FT_4、TSH、FT_3、三酰甘油(TG)、总胆固醇(TCHO)、LDL-C、HDL-C等指标,由此分析患者的血脂水平与甲状腺功能的相关性。结果实施手术前HDL-C与TSH水平呈正相关(P0.05),其他指标与甲状腺功能未见明显相关性(P0.05);停药前血脂水平与甲状腺功能未见明显相关性(P0.05);停药后总胆固醇水平与FT_3、FT_4水平呈负相关(P0.05);HDL-C与FT_3、FT_4水平呈负相关(P0.05),与TSH水平呈正相关(P0.05);LDL-C与FT_4呈负相关(P0.05)。结论甲状腺激素暂停应用治疗时,随着TSH水平的升高,HDL-C水平有所提升;总胆固醇、HDL-C以及LDL-C水平均与FT_3、FT_4呈负相关,药物停用后患者血脂代谢异常与甲状腺功能减退密切相关。

Analysis on correlation between serum lipids and thyroid function after discontinuation of thyroid hormone in patients with differentiated thyroid cancer

Objective To study the correlation between serum lipids and thyroid function after withdrawn of thyroid hormone in the patients with differentiated thyroid cancer .Methods One hundred and thirty cases of differentiated thyroid carcinoma treated by operative therapy in our hospital form August 2014 to August 2015 were selected .Serum FT4 ,TSH ,FT3 ,triglyceride ,total cho-lesterol ,LDL-C ,HDL-C indexes were detected before discontinuation of levothyroxine sodium (L-T4) ,before operation and 3 weeks after drug withdrawn .Thus the correlation between blood lipid levels and thyroid function was analyzed .Results The HDL-C and the TSH level was positively related before operation (P<0 .05) ,other indexes had no obvious correlation with thyroid function (P>0 .05);the blood lipid levels after medication withdrawn had no obvious correlation with thyroid function (P>0 .05);the total cholesterol levels after medication discontinuation had negative correlation with FT 3 and FT4 levels(P<0 .05);HDL-C was nega-tively correlated with FT3 and FT4 levels(P<0 .05) ,and positively correlated with TSH level (P<0 .05);LDL-C was negatively correlated with FT4 (P<0 .05) .Conclusion When the application treatment of thyroid hormone is suspended ,with the TSH level increase ,the HDL-C level has somewhat elevation ;total cholesterol ,HDL-C and LDL-C levels are negatively correlated with FT 3 and FT4 ,after discontinuation of medication withdrawn ,the blood lipids metabolism abnormality is closely related with thyroid function decline .
