Article Abstract
In this study, we investigated the clinical changes induced by a high fat diet (HFD) and caffeine consumption in a rat model. The mean body weight of the HFD with caffeine (HFDC)-fed rat was decreased compared to that of the HFD-fed rat without caffeine. The levels of cholesterol, triglycerides (TGs), and free fatty acid, as well as the size of adipose tissue altered by HFD, were improved by caffeine consumption. To investigate the metabolites that affected the change of the clinical factors, the urine and serum of rats fed a normal diet (ND), HFD, and HFDC were analyzed using ultra performance liquid chromatography quadruple time-of-flight mass spectrometry (UPLC-Q-TOF-MS), gas chromatography (GC-TOF-MS), and linear trap quadruple mass spectrometry (LTQ-XL-MS) combined with multivariate analysis. A total of 68 and 52 metabolites were found to be different in urine and serum, respectively. After being fed caffeine, some glucuronide-conjugated compounds, lysoPCs, CEs, DGs, TGs, taurine, and hippuric acid were altered compared to the HFD group. In this study, caffeine might potentially inhibit HFD-induced obesity and we suggest possible biomarker candidates using MS-based metabolite profiling.

Objectives: To investigate the mechanism of (QJZ) for ameliorating renal damage in MRL/lpr mice.
Methods: With 6 female C57BL/6 mice as the normal control group, 30 female MRL/lpr mice were randomized into model group, QJZ treatment groups at low, moderate and high doses, and prednisone treatment group (6). After 8 weeks of treatment, the mice were examined for 24-h urine protein, creatinine and albumin levels, serum levels of IgG, complement 3 (C3), C4, anti-dsDNA, interferon γ (IFN‑γ) and interleukin 17 (IL-17).

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the most prevalent urological condition in men under 50, characterized by persistent or recurrent pelvic and perineal pain, and significantly reduced quality of life. Reliable biomarkers for assessment and mechanistic understanding of pain remain limited. This retrospective case-control study consisting of 90 CP/CPPS patients (median age 29.

Autosomal Dominant Osteopetrosis (ADO) is a rare, osteosclerotic disorder usually caused by missense variants in the CLCN7 gene, resulting in impaired osteoclastic bone resorption. Penetrance is incomplete and disease severity varies widely, even among relatives within the same family. Although ADO can cause visual loss, osteonecrosis, osteomyelitis, and bone marrow failure, the most common complication of ADO is fracture.

Background: Advanced glycation end-products result from chemical modification of proteins under conditions of hyperglycemia or oxidative stress common with advancing age. Advanced glycation end-product (AGE) formation alters vascular and cardiac structure and function, yet the prospective associations of circulating AGEs with heart failure (HF) and atrial fibrillation (AF) have not been studied.
Methods: We evaluated the associations of serum N-carboxymethyl-lysine (CML), a major AGE in tissue proteins, and incident HF and AF in the CHS (Cardiovascular Health Study), a population-based cohort of older adults.

Objective: Traditional Chinese medicine exhibits positive therapeutic effects as a primary or adjunctive treatment for diabetic nephropathy (DN). This study aimed to evaluate the impact and mechanism of action of Xiaoke decoction (XKD), a traditional Chinese medicine, on renal function in DN rats.
Methods: A rat model of DN was established, and the rats were divided into five groups (n = 7 per group): normal control group (NC), DN model group (DN), low-dose XKD treatment group (DN + XKD-L, 1.
