ABSTRACT
Objective To study the relationship between estradiol (E2) and embryonic development, and to explore the optimal therapeutic regimen for threatened abortion with low estrogen. Methods One hundred and sixty threatened abortion patients 14 days after frozen embryo transfer (FET) with E2 in the range of 100-200 pg/mL were randomized into Chinese medicine group 1, Chinese medicine group 2, Chinese and western medicine group, and control group, 40 cases in each group. Chinese medicine group 1 was treated orally with Shoutai Sijun Decoction, Chinese medicine group 2 was treated orally with Shoutai Sijun Decoction combined with Placenta Hominis Granules, Chinese and western medicine group was treated orally with Shoutai Sijun Decoction combined with Femonstone white tablets, and the control group was treated orally with Femonstone white tablets. Pregnancy rate and the changes in E2 level before and after treatment in the 4 groups were compared. The sensitivity and specificity of E2 level to the prognosis of pregnancy were also investigated. Results (1) The pregnancy rate of Chinese medicine group 1, Chinese medicine group 2, Chinese and western medicine group, and control group was 70.0％, 75.0％, 95.0％, 77.5％ respectively, and Chinese and western medicine group had the highest pregnancy rate(P<0.05).(2) E2 level in the pregnant patients of 4 groups after treatment was increased, and the difference was significant compared with that on ET day 14 (P < 0.05 or P <0.01). (3) The results of prognosis of E2 for pregnancy were as follows: sensitivity was 92％, specificity was 80％, and the area of curve was 0.820 when threshold of E2 being 281 on ET day 22. Conclusion The low post-FET E2 level is correlated with disordered pregnancy, and the early monitoring of E2 and prompt intervention should be performed. Shoutai Sijun Decoction combined with Femonstone white tablets is effective on increasing E2 level rapidly and leading to a higher pregnancy rate, and the effect of Shoutai Sijun Decoction combined with Placenta Hominis Granules comes next.
ABSTRACT
Objective To observe the effect of pigplacenta ins tead of Ziheche (P lacenta Hominis) for the treatment of senile dementia. Methods Seventy Kunming mice were divided into blank group, model group, pos itive control group, Zih eche low and high dosage groups, and pigplacenta low and high dosage grou ps, wi th 10 in each. The senile dementia models were established with the D-Galactose subcutaneous injection. The blank group was not administered any medicines. The model group was prescribed normal saline instead of the tested medicine; the pos itive control group was given Naofukang by gavage; the Zih eche low and high dosage groups were given 2g/kg and 4g/kg Ziheche respectivel y by gavage; while the pigplacenta low and high dosage groups were treated wi th p igplacenta 4g/kg and 8g/kg respectively by gavage. After treatment for 6 week s, the behavior experimental dark-avoiding test and step-down test were applied to test the effect of the medicines on the learning memory of mice, and acetylchol inesterase and monoamine levels in brain tissues. Results There was no s ignificant difference between the effect of pigplacenta and Ziheche in resi stin g senile dementia. In the latency of dark-avoiding test, the effect of high d osa ge of pigplacenta was significantly better than that of Ziheche (P
