Will the risk of stillbirth increase if you encounter extreme heat during pregnancy? This issue is becoming more and more concerned in the context of intensifying climate change. A prospective longitudinal study based on a Chinese birth cohort study involving more than 240,000 pregnant women gave a more refined answer: the key window period for high temperature exposure to increase the risk of stillbirth is not the entire pregnancy, but is concentrated at 32-36 weeks of gestation, especially at 35 weeks of gestation; What is even more surprising is that the high humidity environment did not exacerbate the harm of high temperatures, but showed an antagonistic effect - the risk of stillbirth in dry heat conditions was much higher than in humid heat conditions. This finding has important value for obstetric clinical guidance and public health policy formulation. The latest research results of Professor Liu Ruixia's team from Beijing Obstetrics and Gynecology Hospital Affiliated to Capital Medical University were published in the authoritative journal "Environmental Research" in the field of environment. Based on the Chinese birth cohort study, the research team covered 334,924 pregnant women recruited from 52 hospitals in Chinese mainland between February 2018 and December 2022, and finally included 244,204 pregnancies after exclusion, including 243,262 live births and 942 stillbirths. Stillbirth is defined as a gestational age of ≥ 20 weeks and no signs of life at birth, excluding termination of pregnancy due to fetal abnormalities.

Recently, the research team led by Professor Chenghong Yin at Beijing Obstetrics and Gynecology Hospital, Capital Medical University, published a paper titled “CDH4/UBA1/RBMX axis promotes polycystic ovary syndrome progression through YAP1 activation” in the CAS Q1 journal Cellular & Molecular Biology Letters. This study confirms that abnormal proliferation of ovarian granulosa cells promotes ovarian dysfunction in polycystic ovary syndrome (PCOS) and reveals for the first time the molecular mechanism by which the CDH4/UBA1/RBMX axis regulates abnormal granulosa cell proliferation. In PCOS patients, reduced apoptosis and abnormal proliferation of ovarian granulosa cells are core causes of ovulatory dysfunction and infertility. CDH4 acts as a “molecular switch” that is abnormally highly expressed in the ovarian granulosa cells of PCOS patients. By manipulating a novel UBA1-RBMX-YAP1 signaling axis, it not only exacerbates ovarian inflammation but also blocks normal apoptosis of granulosa cells, providing a highly promising new therapeutic target for PCOS.

With the rapid integration of AI technology into healthcare, AI-assisted scenarios such as diagnosis and treatment, scientific research, and patient management have gradually entered daily OBGYN practice, providing new ways to improve workflow efficiency and optimize clinical quality. To discover outstanding AI-enabled practices, select reusable and high-value clinical cases, and help more OBGYN professionals master AI applications, China OBGYN Network officially launches the 1st AI Clinical Application Case Competition. Through competition we promote learning; through learning we promote practice — empowering the upgrading of clinical care.

On March 16, 2026, the pathology team of Jinan Maternal and Child Health Hospital published an article titled "Clinicopathologic and Molecular Landscape of Villitis of Unknown Etiology: Insights From a Large-Scale Case– Control Study in PR China. The study established a large case-control cohort of VUE from China, and systematically analyzed the clinicopathological correlates and their molecular characteristics of VUE. The article is now compiled as follows:

National Health Commission press conference focuses on women's health: experts explain pelvic floor diseases, uterine fibroids, menopause and HPV vaccines in detail On March 18, 2026, the National Health Commission held a press conference on the theme of "Seasonal Solar Terms and Health", inviting a number of experts to answer reporters' questions on public concerns such as spring health care and the prevention and treatment of common diseases. Among them, Sun Xiuli, chief physician of Peking University People's Hospital, and Yu Wenzhou, chief physician of the Chinese Center for Disease Control and Prevention, gave detailed answers on topics such as pelvic floor health, uterine fibroids, menopausal management, and HPV vaccination that women are concerned about, and clarified a number of common misunderstandings.

For women with BRCA1 gene mutations, fate always seems to draw a cruel multiple-choice question between "removing organs to prevent future diseases" and "preserving fertility but bearing a huge risk of cancer". At the end of 2025, Hollywood actress Angelina Jolie publicly displayed the scars left by removing the breast glands to prevent cancer, once again putting the plight of this group in the public eye. However, a ray of research from the field of biomedical engineering may completely rewrite the answer to this multiple-choice question. On January 28, 2026, the top international academic journal "Cell" reported on a major breakthrough made by Beihang University as the first completion unit in this field: a flexible implantable bioelectronic device called POCKET, which is expected to make "Julie" no longer face the desperate situation of "choosing one of the two".

In order to commend the advanced, set an example, and give full play to the exemplary role of advanced models and exemplary figures, the All-China Women's Federation decided to award Lan Zhen and 9 other people the title of National 38 Red Flag Bearer Pacesetter, Ruan Xiangyan and 598 others the title of National 38 Red Flag Bearer, 400 units including the Memorial Hall of the Chinese People's War of Resistance Against Japanese Aggression and the Ministry of Social Education, and 600 units including the Department of Otolaryngology, Head and Neck Surgery of Beijing Tongren Hospital Affiliated to Capital Medical University the title of National Women's Civilized Post.
