研究设计:

Study design:

Case-Control study 

研究目的:

本研究将基于危重症产妇外周血、脐带血和阴道分泌物标本的 mNGS 数据, 溯源危重症产妇脐带血微生物组,旨在揭示 XX 菌种通过“外周血-胎盘-脐 带血”轴或“阴道-胎盘-脐带血”轴对新生儿预后的影响。  

Objectives of Study:

This study will utilize the mNGS data from peripheral blood, umbilical cord blood, and vaginal secretion samples of critically ill pregnant women to trace the microbial composition of the umbilical cord blood of these patients. The aim is to reveal the impact of the XX strain on the neonatal prognosis through the "peripheral blood - placenta - umbilical cord blood" axis or the "vagina - placenta - umbilical cord blood" axis.

纳入标准:

Inclusion criteria

排除标准:

1.采样不完整或关键样本量不足(任一所需样本缺失/明显污染/凝血严重 影响检测)。 2.分娩前 72 小时内侵入性阴道或宫腔操作(如宫腔镜、宫腔灌洗等), 可能造成不可区分的“外源性引入”。 3.近 7 天内阴道局部用药/冲洗或含活菌的阴道制剂使用(如确有使用, 先不排除,但需单列“干预亚组”)。 4.合并恶性肿瘤近期化疗/放疗、器官移植后强免疫抑制等极端免疫状态。

Exclusion criteria:

1. Incomplete sampling or insufficient key sample quantity (any required sample missing/obviously contaminated/severely clotted, affecting testing). 2. Invasive vaginal or intrauterine procedures within 72 hours before delivery (such as hysteroscopy, uterine irrigation, etc.) that may cause indistinguishable 'exogenous introduction.' 3. Vaginal local medication/washing or use of live-bacterial vaginal products within the past 7 days (if used, do not exclude yet, but list separately as an 'intervention subgroup'). 4. Extreme immune conditions such as recent chemotherapy/radiotherapy for malignant tumors or strong immunosuppression after organ transplantation.
