冻融胚胎移植中舌象和脉象指标与活产结局的相关性研究

Correlation between tongue and pulse indicators and the outcome of live birth in frozen-thawed embryo transfer

目的探讨冻融胚胎移植(FET)患者舌象和脉象指标与活产结局的相关性,及其与患者内分泌指标的关联性。方法本研究于2021年3月8日-2022年1月5日在上海中医药大学附属曙光医院生殖医学中心进行。根据活产结局将FET患者分为活产组和非活产组。分析两组的内分泌指标[基础促卵泡生成素(b FSH)、基础促黄体生成素(b LH)、基础雌二醇(bE_(2))、基础孕酮(bP)、基础子宫内膜厚度、内膜转换日促卵泡生成素(FSH)、内膜转换日促黄体生成素(LH)、内膜转换日雌二醇(E_(2))、内膜转换日孕酮(P)、内膜转换日子宫内膜厚度]与舌象和脉象指标[舌质(TB)-L,TB-a,TB-b,舌苔(TC)-L,TC-a,TC-b,perAll,perPart,h_(1),h_(4),h_(5),t_(1),h_(1)/t_(1),h_(4)/h_(1)]之间的差异,并用Spearman相关系数分析以上变量之间的相关性。采用多元logistic回归分析方法,筛选基于不同数据集的活产预测模型中的影响因素,包括仅由内分泌指标组成的模型1、仅由舌象和脉象指标组成的模型2、由舌象和脉象指标以及内分泌指标组成的模型3,并对不同数据集模型的有效性进行评价。结果研究纳入活产组78例,非活产组144例。与非活产组相比,活产组的TB-L(P=0.01)和TB-a(P=0.04)升高,b FSH(P=0.01)、perAll(P=0.04)和h_(4)/h_(1) P=0.03]降低。Spearman相关分析显示,活产组的TB-L、TB-b、TC-L、TC-b、perAll、perPart、h_(4)、h_(5)、t_(1)、h_(1)/t_(1)与b FSH、bLH、基础子宫内膜厚度、内膜转换日LH、内膜转换日E_(2)、内膜转换日P、内膜转换日子宫内膜厚度的相关性均有统计学意义(P<0.05)。多元logistic回归分析显示,模型3[曲线下面积(AUC):0.917,95%置信区间(CI):0.863-0.971,P<0.001]优于模型1(AUC:0.698,95%CI:0.593-0.803,P=0.001)和模型2(AUC:0.790,95%CI:0.699-0.880,P<0.001)。将舌象和脉象指标与内分泌指标相结合,建立活产结局的回归方程,最终纳入以下指标:内膜转换日FSH[比值比(OR):0.523,P=0.025]、内膜转换日LH(OR:1.277;P=0.029)、TB-L(OR:2.401,P=0.001)、perPart(OR:1.018,P=0.013)、h_(1)(OR:0.065,P=0.021)、t_(1)(OR:4.354,P=0.024)、h_(4)/h_(1)(OR:0.018,P=0.016)。结论在接受FET治疗的不孕症患者中,舌象和脉象指标与内分泌指标之间存在相关性。舌象和脉象指标的加入显著提高了模型对活产结局的预测能力。具体而言,舌象和脉象指标TB-L、PerPart、h_(1)、t_(1)和h_(4)/h_(1)与最终的活产结局有明显的相关性。

Objective To investigate the correlation between tongue and pulse indicators and the out-come of live birth in patients undergoing frozen-thawed embryo transfer(FET),as well as the association between these indicators and patients’endocrine parameters.Methods This study was conducted at Reproductive Medicine Center,Shuguang Hospital Af-filiated to Shanghai University of Traditional Chinese Medicine,Shanghai,China,from March 8,2021 to January 5,2022.Patients undergoing FET were divided into live birth and non-live birth groups according to their live birth outcome.The differences between the endocrine pa-rameters[basic follicle stimulating hormone(b FSH),basic luteinizing hormone(b LH),basic estradiol(b E2),basic progesterone(b P),basal endometrial thickness,follicle stimulating hormone(FSH)on endometrial transition day,luteinizing hormone(LH)on endometrial transition day,estradiol(E2)on endometrial transition day,progesterone(P)on endometrial transition day,and endometrial thickness on endometrial transition day]and the tongue and pulse indicators[tongue body(TB)-L,TB-a,TB-b,tongue coating(TC)-L,TC-a,TC-b,perAll,perPart,h_(1),h_(4),h_(5),t_(1),h_(1)/t_(1),and h_(4)/h_(1)]of patients in the two groups were analyzed,with the correlation between these variables analyzed as well using Spearman’s correlation coefficient.Multivariate logistic regression was employed to identify the influential factors in the live birth prediction models across various datasets,including Model 1 consisting of endocrine indica-tors only,Model 2 solely consisting of tongue and pulse indicators,and Model 3 consisting of both tongue,pulse,and endocrine indicators,as well as to evaluate efficacy of the models de-rived from different datasets.Results This study included 78 patients in live birth group and 144 patients in non-live birth group.Compared with non-live birth group,live birth group exhibited higher levels of TB-L(P=0.01)and TB-a(P=0.04),while demonstrated lower levels of b FSH(P=0.01),perAll(P=0.04),and h_(4)/h_(1)(P=0.03).The Spearman’s correlation coefficient analysis revealed statisti-cally significant correlation(P<0.05)between TB-L,TB-b,TC-L,TC-b,perAll,perPart,h_(4),h_(5),t_(1),h_(1)/t_(1) and b FSH,b LH,basal endometrial thickness,LH on endometrial transition day,E2 on endometrial transition day,P on endometrial transition day,and endometrial thickness on endometrial transition day in live birth group.The multivariate logistic regression analysis showed that the prediction Model 3 for live birth outcome[area under the curve(AUC):0.917,95%confidence interval(CI):0.863−0.971,P<0.001]surpassed the Model 1(AUC:0.698,95%CI:0.593−0.803,P=0.001),or the Model 2(AUC:0.790,95%CI:0.699−0.880,P<0.001).The regression equations for the live birth outcomes,integrating tongue and pulse indicators with endocrine parameters,included the following measures:FSH on endometrial transition day[odds ratio(OR):0.523,P=0.025],LH on endometrial transition day(OR:1.277,P=0.029),TB-L(OR:2.401,P=0.001),perPart(OR:1.018,P=0.013),h_(1)(OR:0.065,P=0.021),t_(1)(OR:4.354,P=0.024),and h_(4)/h_(1)(OR:0.018,P=0.016).Conclusion In infertility patients undergoing FET,there exists a correlation between tongue and pulse indicators and endocrine parameters.The corporation of tongue and pulse indica-tors significantly improved the predictive capability of the model for live birth outcomes.Specifically,tongue and pulse indicators such as TB-L,perPart,h_(1),t_(1),and h_(4)/h_(1) exhibited a discernible correlation with the ultimate live birth outcomes.
