ABSTRACT
Objective To investigate the effect of levothyroxine tablets on subclinical hypothyroidism in pregnancy.Methods One hundred and twenty patients with the subclinical hypothyroidism in hospital were divided into four groups,subclinical hypothyroidism + TPOAb (+) treatment group (39 cases),subclinical hypothyroidism + TPOAb(+) untreated group (15 cases),subclinical hypothyroidism + TPOAb (-) treatment group(26 cases) and subclinical hypothyroidism + TPOAb (-) untreated group (40 cases).Patients in the treatment groups were administrated with levothyroxine tablets.Results The levels of thyroid stimulating hormone(TSH) in subclinical hypothyroidism and TPOAb(+) treatment group were significantly lower(16-20 weeks and 28-32 weeks) at after treatment,which was also lower than that in B group(t =5.671,6.661,P ＜ 0.001).Compared with the untreated group,there was a significant difference in terms of average gestational age,fetal weight ((39.3 ± 1.6) weeks vs.(37.9 ± 1.4) weeks ; (3524 ± 562) g vs.(3101 ± 351) g,t =4.561,7.834,P ＜ 0.001) between A and B groups.In B group,premature birth,gestational hypertension,incidence of placental abruption were significantly higher than that in A group (26.67％ and 2.56％,x2 =7.490,P ＜ 0.001 ; 5.13％ and 40.00％,x2 =10.438,P ＜ 0.001 ; 0 and 13.33％,x2 =5.400,P =0.020).In C group after 16 weeks of treatment,TSH levels at (16-20) weeks and (28-32) weeks were significantly decreased.Compared with the D group,the differences were statistically significant (t =4.980 and 5.432,both P ＜ 0.001).There was no significant difference in C group and D group in terms of pregnancy outcome (P ＞ 0.05).Conclusion Patients with gestational subclinical hypothyroidism such as mergers TPOAb(+) should be treated in time.Prompt treatment can significantly reduce the incidence of adverse pregnancy outcomes,but if patient with TPOAb(-),It is recommended not to conduct any treatment.
ABSTRACT
OBJECTIVE: To investigate the expression of insulin receptor substrate-1 (IRS-1) and phosphorylation of tyrosine in androgen sterilized rats (ASRs) and the effects of Bushen Huoxue Huayu Recipe (BHHR), a compound Chinese herbal medicine for tonifying kidney and activating blood, on the ASRs, and to analyze the possible mechanism. METHODS: ASR models were established by means of testosterone injected subcutaneously at the age of 9 days. The model rats were randomly divided into BHHR group (n=15) and untreated group (n=15); the rats in normal group (n=15) were injected with oil. The rats in the BHHR group were treated with BHHR for 30 days, and the rats in model group and normal group were treated with distilled water for 30 days. Body weight and area under the curve (AUC) of insulin were measured after treatment. Expression of IRS-1 and phosphorylation of tyrosine in adipose tissue in ASRs were analysed by immunohistochemical method. RESULTS: The body weight and insulin AUC in the untreated group were increased and more than those in the BHHR group and the normal control group (P<0.05). Expression of IRS-1 and phosphorylation of tyrosine in normal group were significantly higher than those in the untreated group (P<0.05), and those in BHHR group were improved and significantly different from those in the untreated group (P<0.05). CONCLUSION: BHHR can increase the expression of IRS-1 and phosphorylation of tyrosine in adipose tissue in IR rats, which may be one of its mechanisms in improving insulin sensitivity of the target tissues.
