目的 分析围绝经期女性糖脂代谢水平与卵巢储备功能减退（DOR）的相关性，并探讨绝经激素治疗的应用价值。方法 回顾性选取2024年2月至2026年2月就诊于本院的194例围绝经期女性为研究对象，根据其卵巢储备功能将其分为DOR组（n=103）与卵巢储备功能正常组（NOR，n=91）。比较2组临床资料，采用Logistic回归分析围绝经期女性DOR的危险因素，绘制ROC曲线分析其预测效能，并利用Spearman相关系数分析指标相关性。同时予以所有患者绝经激素治疗（MHT），比较治疗前后的性激素指标、糖代谢指标、超声指标及安全性指标。结果 Logistic多因素结果显示：年龄、FSH、HbA1c、TG是围绝经期女性DOR的重要影响因素（P＜0.05）。ROC结果显示：联合预测的AUC=0.982，95%CI为0.964~1.000，灵敏度为0.990，特异度为0.923，校准曲线拟合性好。卵巢储备功能与年龄、FSH、HbA1c、TG均呈显著正相关（P均<0.05）。与治疗前相比，FSH、LH、HbA1c、TG、LDL-C水平有明显下降（P＜0.05），子宫内膜厚度略有增加（P＜0.05）；AMH、卵巢体积无显著变化（P＞0.05）。MHT治疗后不良反应发生率为4.64%。结论 糖脂代谢异常与围绝经期女性DOR密切相关，是其重要危险因素。规范MHT干预可有效改善内分泌代谢紊乱，且安全性可靠。

Objective To analyze the correlation between glycolipid metabolism levels and diminished ovarian reserve (DOR) in perimenopausal women, and to explore the application value of menopausal hormone therapy.Methods A total of 194 perimenopausal women admitted to our hospital from February 2024 to February 2026 were retrospectively enrolled. They were divided into the DOR group (n=103) and the normal ovarian reserve (NOR) group (n=91) according to ovarian reserve function. Clinical data were compared between the two groups. Logistic regression analysis was used to identify risk factors for DOR. Receiver operating characteristic (ROC) curves were plotted to evaluate predictive efficacy, and Spearman correlation analysis was performed to assess indicator correlations. All patients received menopausal hormone therapy (MHT). Sex hormone indicators, glycolipid metabolic indicators, ultrasonographic indicators and safety indicators were compared before and after treatment.Results Multivariate Logistic regression showed that age, folliclestimulating hormone (FSH), glycated hemoglobin A1c (HbA1c) and triglyceride (TG) were independent risk factors for DOR in perimenopausal women (P＜0.05). ROC analysis revealed that the combined prediction yielded an AUC of 0.982 (95%CI: 0.964–1.000), with a sensitivity of 0.990 and a specificity of 0.923, and good calibration curve fitting. Ovarian reserve was significantly positively correlated with age, FSH, HbA1c and TG (all P＜0.05). After treatment, levels of FSH, luteinizing hormone (LH), HbA1c, TG and lowdensity lipoproteincholesterol (LDLC) decreased significantly (P＜0.05), and endometrial thickness increased slightly (P＜0.05). No significant changes were observed in antiMüllerian hormone (AMH) and ovarian volume (P＞0.05). The incidence of adverse reactions after MHT was 4.64%.Conclusion Abnormal glycolipid metabolism is closely associated with DOR and serves as a critical risk factor in perimenopausal women. Standardized MHT can effectively improve endocrinemetabolic disorders with satisfactory safety.

大蒜为百合科葱属植物的地下鳞茎,具有药食两用的价值,其含有大蒜素、二烯丙基硫醚、二烯丙基二硫醚、二烯丙基三硫醚、 硫-烯丙基半胱氨酸等多种生物活性成分,具有抗氧化、抗感染、免疫调节、心血管保护、抗癌等作用。不仅如此,大蒜在糖脂代谢的调节中功效显著,且相关机制日益明晰,主要包括保护胰岛β细胞功能、改善胰岛素抵抗、阻止脂肪细胞生长、抑制脂合成代谢及调节肠道菌群分布等。不同的提取工艺可影响大蒜的功效,其提取手段及药效关系值得进一步研究。

Garlic has values of both medicine and food,with rich allicin,diallyl disulfide（DADS）,diallyl trisulfide（DATS）and other garlic sulfur contents,which have been found to have multiple effets such as antioxidant,anti-infection,immunomodulatory,cardiovascular protection,anti-cancer,etc．Moreover,numerous studies have demonstrated that garlic plays an important role in the regulation of glycose and lipid metabolism,and the relevant mechanisms are becoming better understood,including protecting pancreatic β cells,improving insulin resistance,preventing the growth of fat cells,inhibiting lipid anabolism and adjusting the distribution of intestinal microflora．Different extraction processes can affect the efficacy of garlic,and further investigations are needed to elucidate the relationship between effective extraction methods and pharmacodynamic properties．
