polysaccharide exhibits therapeutic potential for ovarian fibrosis in PCOS rats via the TGF-1/smad pathway.

Polycystic ovarian syndrome (PCOS) is one of the commonest endocrinopathies in childbearing women. The research was conducted to assess the impact of polysaccharide (ILP, 1000 mg/kg) on the letrozole (1 mg/kg)-induced PCOS model in female rats. Metformin (Met, 265 mg/kg) as the positive control.

Case report: Duodenal obstruction caused by gastroduodenal artery pseudoaneurysm with hematoma: an unusual case and literature review.

Visceral artery pseudoaneurysm is a rare disease that most commonly occurs in male patients in their 50s, with gastroduodenal artery (GDA) pseudoaneurysm accounting for only 1.5% of these. The treatment options generally include open surgery and endovascular treatment.

Rhamnocitrin decreases fibrosis of ovarian granulosa cells by regulating the activation of the PPARγ/NF-κB/TGF-β1/Smad2/3 signaling pathway mediated by Wisp2.

Background: Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility in women. Rhamnocitrin (Rha) has anti-inflammatory and antioxidant actions. The WNT1-inducible-signaling pathway protein 2 (Wisp2) and nuclear factor (NF)-κB are involved in fibrosis in many diseases.

[Studies on the chemical constituents of the petroleum ether portion of Nervilia fordii].

Objective: To study the chemical constituents of the petroleum ether portion of Nervilia fordii.

Methods: The constituents were separated and purified by using column chromatography with silica gel. These compounds were identified by their physical and spectral data.

[Analysis of essential oil from the leaves and fruits of Eucalyptus tereticornis in Guangxi province by GC-MS].

Objective: To Analyze the chemical composition and their relative contents of essential oil from the leaves and fruits of Eucalyptus tereticornis in Guangxi province.

Methods: The column temperature was controlled by a program with a capillary column HP-5 MS, and the MS analysis was performed with EI and quadrupole mass analyzer. The chemical compositions were identified by NIST98 searching and mass spectra comparing, and their relative contents were determined by using normalization method of chromatographic peak areas.

[Studies on the chemical constituents of the ethyl acetate portion of Nervilia fordii].

Objective: To study the chemical constituents of the ethyl acetate portion in the herb of Nervilia fordii from guangxi.

Methods: The constituents were separated and purified by using column chromatography with silica gel. These compounds were identified by their physical and spectral data.
