Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies in reproductive-aged women. The occurrence of PCOS was reported to be associated with the alteration of gut microbiota. Microbiota-derived indoles may possibly play a key role in glycemic control.

Background: The clinical application of autologous leukocyte-poor platelet-rich plasma (LP-PRP) in patients with recurrent implantation failure (RIF) is rare. This retrospective observational cohort study aimed to evaluate the efficacy of LP-PRP intrauterine infusion in patients with RIF.

Methods: Patients with RIF undergoing frozen embryo transfer (FET) from January 2019 to December 2021 ( = 118) were enrolled, with those undergoing LP-PRP intrauterine infusion as the PRP group ( = 64), and those receiving no LP-PRP treatment as the control group ( = 54).

Background: The polycystic ovary syndrome (PCOS) is the most common endocrine associated with insulin resistance, even in the absence of overweight. The global lipid profile of the follicular fluid in PCOS with normal weight as yet has not been investigated. The objection of this pilot study was to explore the changes of lipids in the follicular fluid of PCOS with normal weight.

A new method was established for the determination of indoles (indole (IND), 3-methylindole (3-MI), indolyl-3-acetic acid (IAA) and indolyl-3-propionic acid (IPA)) in plasma by high performance liquid chromatography-fluorescence detection (HPLC-FLD). The analytes were separated simultaneously on a Shim-pack VP-ODS column (150 mm×4.6 mm, 4.

A capillary electrically driven assay with electrochemiluminescent (ECL) detection for total bile acids in human serum was developed and fully validated. Quantification was performed by multiple reactions. First, the bile acids react with nicotinamide adenine dinucleotide (NAD(+)) under catalysis of 3α-hydroxysteroid dehydrogenase (3α-HSD), which is converted to 3-ketosteroid and concomitantly NAD(+) turns into reduced nicotinamide adenine dinucleotide (NADH).

A high performance liquid chromatographic (HPLC) method with programmed wavelength ultraviolet (UV) detection was established to simultaneously determine tryptophan (Trp) and its key metabolites kynurenine (Kyn) and 5-hydroxytryptamine (5-HT). A BDS-Hypersil-C8 column (150 mm x 4.6 mm, 5 microm) was used for the analysis at 25 degrees C.
