Ethnopharmacological Relevance: Si-Wu-Tang (SWT) has become a common basic prescription for supplementing blood and regulating menstruation, and enjoys the reputation of "the first prescription in gynecology". It is often reported in the treatment of premature ovarian failure (POF). However, knowledge of its specific mechanism is still limited.
Aim Of The Study: This study aimed to identify the potential effects and underlying mechanisms of SWT on POF.
Materials And Methods: After confirming the therapeutic effect of SWT on POF mice induced by cyclophosphamide, we further clarified the promoting effect of SWT on ovarian follicle development by detecting the expression of key factors related to follicle development in the ovary in different ways.Then, network pharmacology and gene expression profiling of POF from the GEO database were used to clarify the underlying mechanisms. Molecular biology and molecular docking analysis were applied for final mechanism verification.
Results: Our results showed that SWT increased body weight, ovarian index, reversed disordered serum hormone levels, and menstrual cycle in POF mice. After SWT treatment, the number of follicles at all levels in mice with POF also recovered. Using molecular biology techniques, it was proven that SWT can improve follicle development and angiogenesis in the microenvironment. The network pharmacology and gene expression profiling from the GEO database indicated that the PI3K/Akt signaling pathway may be the reason why SWT improves ovarian function in mice with POF. Subsequently, further Western blot and immunoprecipitation indicated that SWT indeed inhibited the PI3K/Akt signaling pathway in mice with POF. In addition, this conclusion was further confirmed by molecular docking experiments.
Conclusions: SWT can improve ovarian function in POF mice induced by cyclophosphamide, and its mechanism is related to the inhibition of the PI3K/Akt signaling pathway.

Introduction: Ovarian cancer (OC) is the sixth most common malignancy in women and the poor 5-year survival emphasises the need for novel therapies. NK cells play an important role in the control of malignant disease but the nature of tumour-infiltrating and peripheral NK cells in OC remains unclear.
Methods: Using flow cytometric analysis, we studied the phenotype and function of NK cells in blood, primary tumour and metastatic tissue in 80 women with OC.

Nucleoporins, as major components of nuclear pore complex, have been recently discovered to participate in organ development. Here, we report a young female patient with nephrotic proteinuria resistant to immune suppressant treatment and congenital ovarian insufficiency. Renal pathology confirmed focal segmental glomerulosclerosis and whole-exome sequencing revealed compound heterozygous mutations in Nucleoporin 160 (), NM_015231.

Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility among women of reproductive age, yet the range of effective treatment options remains limited. Our previous study revealed that reduced levels of nicotinamide adenine dinucleotide (NAD) in ovarian granulosa cells (GCs) of women with PCOS resulted in the accumulation of reactive oxygen species (ROS) and mitochondrial dysfunction. However, it is still uncertain whether increasing NAD levels in the ovaries could improve ovarian function in PCOS.
