目的 通過觀察卵巢早衰 POF 患者外周血CD4+CD25+調節性T細胞 Treg 及干擾素-γ（IFN-γ）、轉化生長因子-β(TGF-β)的變化，探討POF的免疫學發病機制。 方法 收集2011年12月－2012年9月就診的POF患者17例，卵巢儲備功能減退 DOR 患者11例，以及生殖中心健康育齡女性16例，流式細胞儀定量檢測外周血Treg數量，Elisa方法檢測血清IFN-γ、TGF-β的水平，并以FSH/LH評價卵巢儲備功能，進行相關性分析。 結果 與對照組相比，POF組和DOR組IFN-γ水平增高 P＜0.01 、TGF-β水平降低 P＜0.01 ，POF患者及DOR患者Treg比例降低 P＜0.01 ，IFN-γ的增高與卵巢儲備功能的下降呈顯著正相關 r=0.70，P＜0.01 。 結論 Treg 和IFN-γ、TGF-β水平與卵巢早衰密切相關，IFN-γ對評估卵巢儲備功能、預測卵巢早衰具有參考價值。
ObjectiveTo systematically review the factors influencing plasma concentration of lamotrigine (LTG) in the treatment of epilepsy in children.Methods Databases including PubMed, EMbase, The Cochrane Library, CNKI, WanFang Data, VIP and CBM were electronically searched to collect clinical studies on the factors influencing plasma concentration of LTG in the treatment of epilepsy in children from database inception to December 2020. Two researchers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. A systematic review was then performed to analyze the factors influencing plasma concentration of LTG in the treatment of epilepsy in children. ResultsA total of 21 studies were included. The results of systematic review suggested that dosage and some combination drugs (valproic acid, carbamazepine, phenytoin sodium, topiramate, ethosuximide, rufinamide, fluoxetine, clonazepam, clobazam and ethinylestradiol) were potential factors influencing LTG concentration. Four gene polymorphisms (UGT1A4 142T>G, UGT1A4 219C>T, UGT1A4 163G>A, and OCT1 M408V A>G), age, weight, sex, and combination drugs (phenobarbital and levetiracetam) might affect the plasma concentration of LTG in children. The effects of oxcarbazepine, 16 gene polymorphisms (UGT1A4 *3 T>G, UGT2B7 211G>T, UGT2B7 372A>G, UGT2B7 735A>G, UGT2B7 801T>A, UGT2B7 802C>T, UGT2B7 161C>T, SCN1A IVS591G>A, SCN2A c.56G>A, SCN2A c.59G>A, MDR1 1236 C>T, MDR1 2677 G>T/A, MDR1 3435 C>T, SLC22A1 1022C>T, ABCB1 3435 C>T and ABCB1 1236C>T), ketogenic diet, and ethnicity (Uygur/Han) on the plasma concentration of LTG in children were not found. Conclusion The plasma concentration of LTG in the treatment of epilepsy in children is affected by many factors, and more high-quality prospective studies should be carried out to further clarify the factors influencing the plasma concentration of LTG in children.
