目的：探讨不同时机宫腔镜检查对反复胚胎移植未孕患者后续体外受精-胚胎移植（IVF-ET）临床妊娠结局的影响。方法：回顾性分析2025年1月至2025年10月于东莞康华医院生殖医学科就诊的206例行IVF-ET助孕研究对象的临床资料。根据宫腔镜检查时机分为三组：A组（胚胎移植前检查，n=82）、B组（胚胎移植1次失败后检查，n=70）、C组（胚胎移植2次失败后检查，n=54）。比较三组研究对象后续IVF-ET周期的临床妊娠率。结果：三组研究对象基线年龄、不孕年限、BMI、AMH等指标差异无统计学意义（P>0.05）。总人群临床妊娠率为53.59%（97/206），其中A组妊娠率为72.0%（59/82），B组为35.7%（25/70），C组为24.1%（13/54），组间差异有统计学意义（P<0.001）。免疫双染阳性研究对象占86.27%（176/206），其在组间分布均衡，未改变主要结论。结论：对于IVF-ET助孕研究对象，胚胎移植前进行宫腔镜检查并处理异常，可能与后续临床妊娠率升高相关；延迟至1次或2次胚胎移植失败后再检查，妊娠获益可能大幅降低。提示胚胎移植前常规行宫腔镜评估的必要性。

Objective: To investigate the impact of different timing of hysteroscopy on the subsequent clinical pregnancy outcomes of patients with recurrent embryo transfer failure undergoing in vitro fertilization - embryo transfer (IVF-ET). Methods: The clinical data of 206 patients who underwent IVF-ET assisted pregnancy treatment at the Reproductive Medicine Department of Dongguan Kanghua Hospital from January 2025 to October 2025 were retrospectively analyzed. The patients were divided into three groups based on the timing of hysteroscopy: Group A (examined before embryo transfer, n = 82), Group B (examined after one failed embryo transfer, n = 70), and Group C (examined after two failed embryo transfers, n = 54). The clinical pregnancy rates of the subsequent IVF-ET cycles of the three groups were compared. Results: There were no statistically significant differences in baseline age, duration of infertility, BMI, AMH, etc. among the three groups (P > 0.05). The overall clinical pregnancy rate of the population was 53.59% (97/206), with the pregnancy rates in Group A being 72.0% (59/82), in Group B 35.7% (25/70), and in Group C 24.1% (13/54). The differences among the groups were statistically significant (P < 0.001). Immunobright staining positive study subjects accounted for 86.27% (176/206), and their distribution among the groups was balanced, without changing the main conclusion. Conclusion: For patients undergoing IVF-ET assisted pregnancy treatment, performing hysteroscopy and treating abnormalities before embryo transfer may be associated with an increased subsequent clinical pregnancy rate; delaying the examination until one or two failed embryo transfers may significantly reduce the pregnancy benefit. It suggests the necessity of routine hysteroscopy assessment before embryo transfer.

Objective To investigate the relationship between abnormal blood glucose items in the 75 g oral glucose tolerance test（OGTT）at 24-28 weeks of pregnancy and the blood glucose levels before delivery in the third trimester of pregnancy and pregnancy outcomes in gestational disbetes mellitus（GDM）patients. Methods All 167 GDM patients diagnosed at 24-28 weeks of gestation in Women and Children's Medical Center Affiliated to Guangzhou Medical University from November 2019 to May 2020 were enrolled as subjects．The pregnant women with only 1 abnormal blood glucose item among the 75 g OGTT results were classified as GDMⅠ group（92 cases）,with 2 abnormal items were GDMⅡ group（48 cases）,and with 3 abnormal items were GDM Ⅲ group（27 cases）．The demographic characteristics of the three groups of GDM patients were compared．The relationship between the general demographic characteristics of GDM patients and the mean value of blood glucose monitoring before delivery in the third trimester was analyzed,and the influence of blood glucose monitoring on adverse pregnancy outcomes was also analyzed．Results ①With different BMI and HbA_1c,there were significant differences in 75 g OGTT blood glucose items（P<0.05）．BMI level had statistically significant effects on fasting blood glucose,1-hour postprandial blood glucose and 2-hour postprandial blood glucose in the third gestational trimester（P<0.05）．②With different number of abnormal blood glucose items,there were significant in fasting blood glucose and 2 hours postprandial blood glucose（P<0.05）．③There were statistically significant differences in the outcomes of neonatal hypoglycemia,premature rupture of membranes and preterm delivery in different fasting blood glucose groups（P<0.05）．There were statistically significant differences in neonatal hypoglycemia and premature rupture of membranes between different 2 hours postprandial blood glucose（P<0.05）. Conclusions BMI can affect the blood glucose screening results of 75g OGTT in the second trimester．The more abnormal blood glucose items in the 75g OGTT test,the greater the probability of adverse pregnancy outcome．Standardized exercise diet intervention and necessary drug intervention during pregnancy can improve the HbA_1c level in the third trimester．

目的 探讨产科监护室妊娠期糖尿病产妇泌乳启动延迟及影响因素,以期作为预防泌乳启动延迟的参考依据。方法 选择2021年1月—2023年5月期间医院产科监护室接收的妊娠期糖尿病产妇80例为研究对象,采用单因素和多因素分析产妇的年龄、体质指数、产次、定期复查血糖、妊娠期高血压、分娩方式、开奶时间、新生儿体质量、产后焦虑、产后抑郁、产后疲乏、吸吮次数等对泌乳启动延迟的影响。结果 妊娠期糖尿病产妇泌乳启动延迟33例,发生率41.25%;泌乳启动延迟产妇的年龄≥35岁者占51.52%、未定期复查血糖者占39.39%、合并妊娠期高血压者占54.55%、开奶时间≥6 h者占57.58%、产后焦虑者占30.0%、产后抑郁者占36.36%、产后疲乏者占36.36%、吸吮次数<6次者占60.61%,与非泌乳启动延迟产妇比较差异均有统计学意义（P<0.05）。两组孕前体质指数、产次、分娩方式、新生儿出生体质量比较差异无统计学意义（P>0.05）。年龄≥35岁、未定期复查血糖、合并妊娠期高血压、开奶时间≥6 h、产后焦虑、产后抑郁、产后疲乏、吸吮次数<6次为妊娠期糖尿病产妇泌乳启动延迟的危险因素（P<0.05）。结论 产科监护室妊娠期糖尿病产妇泌乳启动延迟发生率较高,主要受到年龄、未定期复查血糖、合并妊娠期高血压、开奶时间、产后心理状态、吸吮次数等因素影响,应重视健康教育和早期辅助干预,降低泌乳启动延迟发生率。

Objective To explore the delayed lactation initiation and its influencing factors of pregnant women with diabetes in the obstetric care unit,so as to provide a reference for preventing delayed lactation initiation．Methods A total of 80 pregnant women with diabetes who were received by the hospital obstetric care unit from January 2021 to May 2023 were selected as the research objects．The age,body mass index,parity,regular blood glucose recheck,pregnancy hypertension,delivery mode,starting time,neonatal weight,postpartum anxiety,postpartum depression,postpartum fatigue,sucking times and other factors that led to the delay of lactation initiation were analyzed by single factor and multi factor analysis．Results The onset of lactation was delayed in 33 pregnant women with diabetes,with an incidence of 41.25%．The age of postpartum women with delayed lactation initiation over 35 years old accounted for 51.52%,blood sugar was not regularly rechecked accounted for 39.39%,pregnancy induced hypertension accounted for 54.55%,lactation time over 6 hours accounted for 57.58%,postpartum anxiety accounted for 30.0%,postpartum depression accounted for 36.36%,postpartum fatigue accounted for 36.36%,and sucking frequency <6 times accounted for 60.61%,which were higher than that of non-delayed lactation initiation women（P<0.05）．There was no statistically significant difference between the two groups in terms of pre pre-pregnancy body mass index,parity,delivery method and newborn birth weight（P>0.05）．The risk factors of delayed lactation initiation in pregnant women with diabetes were age ≥ 35 years,no regular blood glucose review,hypertension during pregnancy,≥ 6 h of first milk expression time,postpartum anxiety,postpartum depression,postpartum fatigue and sucking times<6（P<0.05）．Conclusions The incidence of delayed lactation initiation in pregnant women with diabetes in the obstetric care unit is high,which is mainly affected by age,pregnancy induced hypertension,time of starting breast feeding,postpartum psychological state and sucking times．Health education and early auxiliary intervention should be emphasized to reduce the incidence of delayed lactation initiation．

目的 对比分析在产程不同阶段对妊娠期高血压产妇给予分娩镇痛的效果差异。方法 选择2021年1月—2022年12月在福清市妇幼保健院接受无痛分娩治疗的240例妊娠期高血压产妇,随机分为在产程活跃期实施镇痛的对照组（n=120）和产程潜伏期实施镇痛的实验组（n=120）,比较两组产妇的产程时间、子宫动脉、胎儿脐动脉血流动力学参数、镇痛效果以及母婴结局。结果 实验组的第一、第二、第三产程时间分别为（389.71±35.05）（58.62±5.26）（8.71±0.69）min,略低于对照组的（403.72±42.19）（60.74±7.22）（8.91±1.62）min,但组间比较差异无统计学意义（P>0.05）;实验组镇痛前、活跃期、第二产程的疼痛评分分别为（9.18±0.13）（1.16±0.22）（2.83±1.16）分,与对照组的（9.22±0.16）（1.24±0.32）（2.72±1.09）分比较差异无统计学意义（P>0.05）,但在潜伏期,实验组产妇疼痛评分为（3.32±0.36）分,低于对照组的（8.11±0.32）分（P<0.05）;关闭镇痛泵后,实验组胎儿脐动脉阻力指数、搏动指数、收缩期峰值流速/舒张期流速分别为（0.58±0.09）（0.81±0.14）（2.31±0.29）,与对照组的（0.54±0.11）（0.79±0.13）（2.24±0.27）比较差异无统计学意义（P>0.05）,实验组产妇子宫动脉阻力指数、搏动指数、收缩期峰值流速/舒张期流速分别为（0.42±0.08）（0.64±0.08）（2.31±0.29）,均高于对照组的（0.39±0.06）（0.58±0.11）（1.65±0.08）（P<0.05）;实验组自然分娩、中转剖宫产、阴道助产例数及新生儿Apgar评分分别为87例、23例、10例、（8.88±0.15）分,与对照组的83例、28例、9例、（8.81±0.19）分比较差异无统计学意义（P>0.05）。结论 潜伏期与活跃期对妊娠期高血压产妇实施分娩镇痛对产程时间以及母婴结局的影响不大,但潜伏期镇痛可改善产妇潜伏期的疼痛,可尽早缓解产妇痛苦,且对产妇子宫动脉血流灌注的影响更小。
