Meta analysis of infertility due to polycystic ovarian syndrome treated by kidney-tonifying and blood-activating therapy

Objective:To explore the Meta-analysis of polycystic ovary syndrome-induced infertility by tonifying kidney and activating blood circulation.Methods:Chinese keywords or subject words such as"kidney-tonifying and Blood-Activating Therapy","polycystic ovary syndrome","infertility"were searched in CNKI,Wanfang and Weipu databases,and English keywords such as"Kidney-tonifying and Blood-Activating Therapy","Stein-Leventhal syndrome","Infertility"were searched in Pubmed database for a period of 2.From 2000 to 2019,Meta-analysis was carried out with Review Manager 5.0.Results:Thirteen randomized controlled literatures were screened out,and the control group was treated with routine western medicine and the treatment group was treated with Kidney-tonifying and Blood-activating therapy.All of them included literatures mentioned grouping method,but no blind method was mentioned,and the literature quality was generally low.Meta-analysis of the effective rate showed that Z=3.69(P=0.0002<0.001),95%CI(1.77,6.42),indicating that the effective rate in the treatment group was higher than that in the control group.Meta-analysis of the cycle ovulation rate showed that Z=2.19(P=0.03<0.05),95%CI(1.08,4.35),indicating that the cycle ovulation rate in the treatment group was higher than that in the control group.Meta-analysis of pregnancy rate showed that:Z=7.07(P<0.00001),95%CI(2.27,4.24),indicating that the pregnancy rate in the treatment group was higher than that in the control group;bias analysis found that the literature was distributed on both sides of the dotted line,most of which were biased.Meta-analysis of the incidence of LUFS showed that Z=3.25(P=0.001<0.05),95%CI(0.02,0.38),indicating that the incidence of LUFS in the treatment group was lower than that in the control group.Meta-analysis of serum E2 level after treatment showed that Z=4.41(P<0.0001),95%CI(11.01,28.64),indicating that the serum E2 level in treatment group was higher than that in control group after treatment.Conclusion:Meta-analysis shows that the method of tonifying kidney and activating blood circulation has a significant effect on infertility caused by polycystic ovary syndrome.It can improve the level of sex hormones,improve the efficiency,cycle ovulation rate and pregnancy rate,and reduce the incidence of LUFS.However,the quality of the included literature is not high,which needs to be further included in high-quality literature to confirm.

Investigation of Mechanism of Premature Ovarian Failure Regulation by Kidney-tonifying Herbs and Liver-clearing Herbs in Dingjing Decoction

Objective To investigate the mechanisms through which kidney-tonifying herbs（KTHs） and liver-clearing herbs（LCHs） in Dingjing Decoction（DJD） regulate premature ovarian failure（POF）. Methods One hundred and fifty Sprague-Dawley rats were randomly divided into five groups such as control, model, KTHs, LCHs, and DJD groups. POF-related biological molecules were examined. Factor analysis was performed to investigate the regulatory networks and key biomolecules involved in mediating POF after treatment with KTHs and LCHs. Results The master regulatory factors in the reproductive endocrine network associated with KTHs intervention included four molecules in the pituitary-ovarian axis, cortisol（CORT） in the target gland of pituitary-adrenal axis, and some molecules in the hypothalamus. In contrast, the master regulatory factors associated with LCHs intervention included four molecules in the pituitary-ovarian axis and some molecules in the hypothalamus; No biomolecules in the pituitary-adrenal axis were involved in the LCH-mediated mechanisms.Gonadotropin-releasing hormone（Gn RH）, which was identified as a common biological molecule in the hypothalamus, was involved in regulating the reproductive endocrine network in association with KTHs intervention. Conclusion KTHs directly regulates biological molecules in the pituitary-adrenal axis and indirectly regulates those in the pituitary-adrenal axis through the hypothalamus, while the LCHs only exert its effects indirectly. Gn RH is the key biological molecule associated with KTHs intervention.
