Objective To investigate the variation of thyroid hormone therapy in patients with hypothyroidism before,during and postpartum pregnancy.Methods Thirty-eight patients who suffered from hypothyroidism and had successful pregnancy were collected.Among them,15 cases of hypothyroidism were caused by autoimmune thyroiditis caused,11 cases were induced by thyroid surgery; in 131I treatment induced hypothyroidism were 5 cases,7 patients had unclear reason pregnancy clinical thyroid dysfunctions.Thirty-eight cases of non-pregnant patients with hypothyroidism were also collected as the control group.They achieved efficacy standards by levothyroxine (L-T4) treatment and dose variation of L-T4 was statistically analyzed.Results There was a significant difference before pregnancy,postpartum and different periods of pregnancy.L-T4 dose had a significant increase after pregnancy.At 10-12 weeks,16-18 weeks,22-24 weeks,26-30 weeks,34-36 weeks respectively,L-T4 dose was significantly increasing compared with before pregnancy and postpartum 3 months((110.51 ± 10.42),(113.81 ± 21.04),(108.32 ± 21.01),(105.58 ±21.54),(105.89±10.24),(84.42 ±10.45) and (86.43 ±10.29) μg/L,F=15.631,P＜0.001),but between before and pregnancy postpartum,there was not significantly difference (P ＞ 0.05).Among the various stages of pregnancy,there was also no significant difference; In the patients with hypothyroidism due to thyroid surgery and 131I therapy,L-T4 dose were significantly higher than autoimmune thyroiditis and patients with no clear reason(before,during and after pregnancy,F =4.98,5.15,5.04,P ＜ 0.001).Conclusion Patients with hypothyroidism during pregnancy should increased therapeutic dose of thyroid hormone with average about 30％-40％ of the original dose,and in postpartum,levels before pregnancy could resume.High doses of L-T4 treatment should be taken in patients with hypothyroidism after 131I therapy and after thyroid surgeries.

Through decades of innovation and transcendence,foreign medical universities consistently promoted integration of medicine and humanities and carried out curriculum and teaching reform.Both the ideas and measures are advanced and worthy study.Currently,the development of medical humanities education in China is confronted with difficulties.Medical students need to promote their humanistic quality urgently.The study explored the effective measures to innovate and transcend by analyzing the advancement of foreign medical humanities education and problems of medical humanities education in China.
