AI Article Synopsis
- Jiao-Ai Decoction (JAD) is a traditional Chinese herbal formula used for a long time in treating abortion, but its components and how it works are not well understood.
- Researchers used advanced techniques, like ultra-performance liquid chromatography and mass spectrometry (UPLC-MS/MS), to identify the chemical components and assess the therapeutic effects of JAD on the hypothalamus-pituitary-ovarian axis (HPOA).
- The study found 101 compounds in JAD and demonstrated that it effectively prevents miscarriage in lab rats by regulating the HPOA and influencing gene and protein expression.
Article Abstract
Jiao-Ai Decoction (JAD), a classical traditional Chinese formula composed of seven Chinese herbs, has been widely used in clinical practice for the treatment of abortion for a long time. However, the material basis and pharmacological mechanism remain unclear. An integrative method combining ultra-performance liquid chromatography coupled with mass spectrometry (UPLC-MS/MS) analysis and therapeutic effect evaluation based on the hypothalamus-pituitary-ovarian axis (HPOA) was employed to elaborate these problems. Firstly, the chemical profile of JAD was identified by UPLC-Q-TOF-MS. Secondly, the main target ingredients from JAD were determined by UPLC-T-Q-MS. Finally, the miscarriage prevention of JAD on threatened abortion pregnant rats induced by mifepristone was investigated. Threatened abortion model in rats were replicated, uterine bleeding quantity (UBQ) and histopathological sections were measured, the contents of luteinizing hormone (LH), follicular stimulating hormone (FSH), estradiol (E) and progesterone (P) were determined by ELISA, related genes and protein expression levels were detected by RT-PCR and western blotting. As a result, a total of 101 compounds were identified and 27 ingredients were determined to evaluate the quality of JAD. In the model rats, JAD could effectively regulate the HPOA to achieve miscarriage prevention, and the mechanism might be related to the regulation of gene and protein expression on the HPOA. This work could provide a novel and valuable approach for the quality evaluation of JAD and were expected to provide ideas and methods for the basic research on the scientific application of similar traditional Chinese medicine prescriptions.

This study investigated the cervicovaginal microbiome's (CVM's) impact on Chlamydia trachomatis (CT) infection among Black and Hispanic adolescent and young adult women. A total of 187 women with incident CT were matched to 373 controls, and the CVM was characterized before, during, and after CT infection. The findings highlight that a specific subtype of bacterial vaginosis (BV), identified from 16S rRNA gene reads using the molBV algorithm and community state type (CST) clustering, is a significant risk factor for CT acquisition.

Sporadic early miscarriages occur primarily due to embryonic aneuploidy. There is no evidence showing that stress is a direct cause of miscarriage. Yet, despite this, a national US survey and a Japanese survey found that many people mistakenly attributed miscarriage to the mental state or behavior of the women.

Miscarriage represents a prevalent yet insufficiently studied adverse pregnancy outcome. The definitive causal links between various pathogens and miscarriage remain to be established. To investigate the causal connections between pathogen infections and miscarriage, we utilized a two-sample bidirectional Mendelian randomization (MR) analysis.

Autoimmune thyroid disease (AITD) is the leading cause of thyroid dysfunction globally, characterized primarily by two distinct clinical manifestations: Hashimoto's thyroiditis (HT) and Graves' disease (GD). The prevalence of AITD is approximately twice as high in women compared to men, with a particularly pronounced risk during the reproductive years. Pregnancy exerts profound effects on thyroid physiology and immune regulation due to hormonal fluctuations and immune adaptations aimed at fostering maternal-fetal tolerance, potentially triggering or exacerbating AITD.

Importance: Rhesus alloimmunization refers to the sensitization of an Rh D-negative mother after exposure to D-positive fetal red blood cells, which can lead to significant fetal and neonatal morbidity and mortality.
Objective: The aim of this study was to review and compare the most recently published international guidelines on the prevention of maternal alloimmunization.
Evidence Acquisition: A comparative review of guidelines from the American College of Obstetricians and Gynecologists, the British Committee for Standards in Hematology, the International Federation of Gynecology and Obstetrics, the Royal Australian and New Zealand College of Obstetricians and Gynecologists, and the Society of Obstetricians and Gynecologists of Canada regarding the prevention of maternal Rh D alloimmunization was conducted.
