Effect of berberine combined with metformin on autophagy in polycystic ovary syndrome by regulating AMPK/AKT/mTOR pathway.

The pathologic mechanism of polycystic ovary syndrome (PCOS) is related to increased autophagy of granulosa cells. Both berberine and metformin have been shown to improve PCOS, but whether the combination of berberine and metformin can better improve PCOS by inhibiting autophagy remains unclear. PCOS models were constructed by injecting dehydroepiandrosterone into rats, and berberine, metformin or berberine combined with metformin was administered to rats after modeling.

Value of soluble fms-like tyrosine kinase 1 for predicting acute pancreatitis severity: a systematic review and meta-analysis.

Objective: The objective of this study was to explore the relationship between serum soluble fms-like tyrosine kinase 1 and the severity of acute pancreatitis and its diagnostic utility.

Methods: This study was carried out by searching Chinese and English literature from the establishment of the database to July 9, 2023, systematically, and assessing the quality and heterogeneity of the articles included.

Results: Thirteen studies with a total of 986 patients were included.

CPEB1 induces autophagy and promotes apoptosis in ovarian granulosa cells of polycystic ovary syndrome.

Inflammatory damage in ovarian granulosa cells (GCs) is a key mechanism in polycystic ovary syndrome (PCOS), cytoplasmic polyadenylation element binding protein-1 (CPEB1) is important in inflammatory regulation, however, its role in PCOS is unclear. We aim to research the mechanism of CPEB1 in ovarian GCs in PCOS using dehydroepiandrosterone (DHEA)-induced PCOS rat models and testosterone-incubated GC models. The pathophysiology in PCOS rats was analyzed.

LncRNA SNHG12 promotes cell proliferation and inhibits apoptosis of granulosa cells in polycystic ovarian syndrome by sponging miR-129 and miR-125b.

Background: Polycystic ovarian syndrome (PCOS) is the most common endocrine disease in women of childbearing age which is often associated with abnormal proliferation or apoptosis of granulosa cells (GCs). Studies proved that long non-coding RNA SNHG12 (lncRNA SNHG12) is significantly increased in ovarian cancer and cervical cancer patients and cells. The inhibition of lncRNA SNHG12 restrains the proliferation, migration, and invasion in tumor cells.

LIPUS combined with TFSC alleviates premature ovarian failure by promoting autophagy and inhibiting apoptosis.

Objective: Premature ovarian failure (POF), also known as primary ovarian insufficiency, is a major cause of infertility in female worldwide. Excessive apoptosis and impaired autophagy in ovarian granulosa cells are the main pathological mechanisms of POF. The total flavonoids from (TFSC) are often used in the treatment of gynecological endocrine disorders.

The ameliorating effects of Guizhi Fuling Wan combined with rosiglitazone in a rat ovarian model of polycystic ovary syndrome by the PI3K/AKT/NF-κB and Nrf2/HO-1 pathways.

Objective: GuizhiFulingWan (GFW) has been reported to be effective against polycystic ovary syndrome (PCOS) by possessing oxidative stress and inflammation which related to PI3K/AKT/NF-κB, Nrf2/HO-1 pathway. This study aims to probe the effects and mechanisms of GFW combined with rosiglitazone on PCOS PI3K/AKT/NF-κB and Nrf2/HO-1 pathways.

Methods: A rat PCOS model established by dehydroepiandrosterone (DHEA) injection.

MicroRNA-646 inhibits the proliferation of ovarian granulosa cells via insulin-like growth factor 1 (IGF-1) in polycystic ovarian syndrome (PCOS).

Introduction: Polycystic ovarian syndrome (PCOS) is a common endocrinopathy in women. MicroRNAs (miRNAs) have been proven to play a crucial role in balancing the proliferation and apoptosis of granulosa cells (GCs) in PCOS.

Material And Methods: The miRNA of PCOS was screened by bioinformatics analysis, and microRNA 646 (miR-646) was found to be involved in insulin-related pathways by enrichment analysis.

The effect of sitagliptin combined with rosiglitazone on autophagy and inflammation in polycystic ovary syndrome by regulating PI3K/AKT/mTOR and TLR4/NF-κB pathway.

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder. Sitagliptin (Sit) and rosiglitazone (Ros) are widely used to treat PCOS, but the mechanism is unclear. This study explored the mechanism that Sit and Ros inhibited autophagy and inflammation in PCOS.

CircRNA circ_0043533 facilitates cell growth in polycystic ovary syndrome by targeting miR-1179.

Increasing evidence indicates that circular RNAs (CircRNAs) have an important role in human diseases, including polycystic ovary syndrome (PCOS). Recently, circ_0043533, a novel circRNA, was proposed to be involved in the progression of PCOS. However, its role in PCOS has not been explored.

Chronic intermittent hypoxia accelerates liver fibrosis in rats with combined hypoxia and nonalcoholic steatohepatitis via angiogenesis rather than endoplasmic reticulum stress.

In the present study, we aimed to investigate the role of endoplasmic reticulum stress (ERS) and its related inflammation and angiogenesis in liver fibrosis in a rat model of combined hypoxia and nonalcoholic steatohepatitis (NASH) and to confirm whether the intervention of hypoxia-inducible factor 1α (HIF1α) can improve fibrosis. Liver histological changes and biochemical indices, HIF1α, inflammatory factors, ERS-related parameters (GRP78, CHOP, caspase-3, and caspase-12), and angiogenesis indices (VEGFA, VEGFR2, and CD34) were evaluated. Compared with the control rats, the liver tissue of rats with hypoxia and NASH had obvious NASH characteristics and hepatic fibrosis was significantly aggravated, including bridging fibrosis in some rats.

Efficacy and Safety of Acupuncture for the Treatment of Functional Dyspepsia: Meta-Analysis.

Objectives: Functional dyspepsia (FD) is a common gastrointestinal disorder. Currently, no established optimal treatment is available. The aim of this study was to assess the efficacy of acupuncture in relieving symptoms and improving quality of life in patients with FD.

miR-19b downregulates intestinal SOCS3 to reduce intestinal inflammation in Crohn's disease.

Although aberrant microRNA (miRNA) expression has frequently been observed in inflammatory bowel disease (IBD), its biological functions and targets remain largely unknown. Present study found that miR-19b was significantly downregulated in active Crohn's disease (CD). Using bioinformatics analysis, suppressor of cytokine signalling 3 (SOCS3), a physiological regulator of innate and adaptive immunity that controls several immuno-inflammatory diseases, was predicted to be a potential target of miR-19b.

Epidermal growth factor upregulates serotonin transporter and its association with visceral hypersensitivity in irritable bowel syndrome.

Aim: To investigate the role of epidermal growth factor (EGF) in visceral hypersensitivity and its effect on the serotonin transporter (SERT).

Methods: A rat model for visceral hypersensitivity was established by intra-colonic infusion of 0.5% acetic acid in 10-d-old Sprague-Dawley rats.
