Association of remnant cholesterol with insulin resistance and type 2 diabetes: mediation analyses from NHANES 1999-2020.

Background: Previous studies have established a correlation between elevated levels of remnant cholesterol (RC) and the occurrence of type 2 diabetes mellitus (T2D) as well as insulin resistance (IR); however, the precise nature of these associations remains incompletely elucidated. This study aimed to evaluate the relationships between RC and IR, as well as RC and T2D, and to determine the extent to which IR mediated the relationship between RC and T2D.

Methods: This was an observational study that utilized cross-sectional methods to examine the general population in the National Health and Nutrition Examination Survey (NHANES) 1999-2020.

Screening parameters for diagnosing primary aldosteronism in patients with moderate to severe obstructive sleep apnea hypopnea syndrome and resistant hypertension.

Background: Patients with obstructive sleep apnea hypopnea syndrome (OSAHS) combined with resistant hypertension (RH) have a high risk of developing primary aldosteronism (PA). This study investigated the aldosterone-renin ratio (ARR), plasma aldosterone concentration (PAC), and plasma renin activity (PRA) to determine the optimal cutoff values for PA diagnosis in patients with OSAHS combined with RH.

Methods: Patients diagnosed with moderate and severe OSAHS combined with RH were recruited from the inpatient clinic of the Department of Endocrinology at Ji'an Central Hospital between October 2020 and April 2023.

Exogenous Hydrogen Sulfide Attenuates High Glucose-Induced Cardiotoxicity by Inhibiting NLRP3 Inflammasome Activation by Suppressing TLR4/NF-κB Pathway in H9c2 Cells.

Background/aims: This study aimed to investigate whether exogenous hydrogen sulfide (H2S) confered cardiac protection against high glucose (HG)-induced injury by inhibiting NLRP3 inflammasome activation via a specific TLR4/NF-κB pathway.

Methods: H9c2 cardiac cells were exposed to 33 mM glucose for 24 h to induce HG-induced cytotoxicity. The cells were pretreated with NaHS (a donor of H2S) before exposure to HG.

The biotransformation of oleuropein in rats.

A highly sensitive and specific LC-MS/MS method was developed to investigate the in vivo bio-transformation of oleuropein in rat. Rat feces and urine samples collected after oral administration were determined by liquid chromatography coupled to tandem mass spectrometry with electrospray ionization in the negative-ion mode. The assay procedure involves a simple liquid-liquid extraction of parent oleuropein and the metabolite from rat feces and urine with ethyl acetate.

[Clinical trials of antiphlogistic agent series in treating chronic nonbacterial prostatitis].

Objective: To investigate the curative effect of antiphlogistic agent series on treating chronic nonbacterial prostatitis (CNP).

Methods: One hundred and sixty patients were randomized into 4 groups for an 8-week clinical observation: group A (oral antiphlogistic medicinal granules only), group B (oral antiphlogistic medicinal granules + retention enema), group C (oral antiphlogistic medicinal granules + rectal), and group D (antiphlogistic medicinal granules + rectally + hip bath). Single blind trials were employed.
