Objectives: In this study, we evaluate the utility of serum metalloproteinase-2 (MMP-2) as a biomarker for the diagnosis of epilepsy.
Methods: We assessed serum MMP-2 levels in 233 epileptic and 97 healthy control subjects. Control subjects had no complaints or signs of neurological disorders for at least 12 months prior to serum collection. Serum MMP-2 levels were determined using the Luminex technology.
Results: Compared with controls, subjects with epilepsy had significantly lower serum MMP-2 concentrations (P<0.05). There was no significant difference between males and females in either group (P>0.05). Serum MMP-2 concentrations were highly correlated with age in both groups, and this correlation was strongest for males. When an MMP-2 cut-off value of 175.40ng/ml was used, the sensitivity for distinguishing subjects with epilepsy from controls was 71.13% and the specificity was 62.66%.
Conclusions: Our results reveal that serum MMP-2 may be a potential biomarker for the diagnosis of epilepsy.

Causal association between matrix metalloproteinases and diabetic neuropathy: a two-sample Mendelian randomization study.
Front Endocrinol (Lausanne)

School of Public Health, Xinjiang Medical University, Urumqi, Xinjiang, China.
Objective: Diabetic neuropathy (DN), a common and debilitating complication of diabetes, significantly impairs the quality of life of affected individuals. While multiple studies have indicated changes in the expression of specific matrix metalloproteinases (MMPs) in patients with DN, and basic research has reported the impact of MMPs on DN, there is a lack of systematic research and the causal relationship remains unclear. The objective of this research is to investigate the casual relationship between MMPs and DN through two-sample Mendelian randomization (MR).

Background: The aim of this study was to investigate the association between dental fluorosis occurrence in children and bone metabolism-related indicators, including bone-specific alkaline phosphatase (BALP), osteocalcin (OC), matrix metalloproteinase (MMP-2, MMP-9, MMP-20), and parathyroid hormone (PTH).
Methods: A total of 189 cases of school-age children who underwent health examinations in our hospital were enrolled, according to the presence or absence of dental fluorosis. They were divided into the fluorosis group (n=97) and fluoride-free group (n=92), and the serum BALP, OC, MMP-2, MMP-9, MMP-20, and PTH levels of the two groups were compared and relevant clinical data were collected.
Phoenixin-14 inhibits the formation of cerebral aneurysms in rats by downregulating the p38/NF-κB signaling pathway.

Department of Neurology, Hospital of Chengdu University of Traditional Chinese Medicine, Chengdu, Sichuan 610072, China. Electronic address:
Cerebral aneurysms (CA) are a serious condition characterized by the bulging of a blood vessel in the brain, which can lead to rupture and life-threatening bleeding. The pathophysiology of CA involves complex processes, particularly inflammation and macrophage infiltration. Phoenixin-14 (PNX-14) is a neuropeptide with diverse biological effects, including roles in reproduction, energy homeostasis, and inflammation.

Betulinic acid (BA) has been shown to exhibit various pharmacological activities and it has shown the protective effect on acute renal failure (ARF) and chronic renal failure (CRF); however, no reports are available on its effect on ARF-CRF transition. Therefore, we aimed to investigate the effects of BA on ARF-CRF transition. A single dose of 250 mg/kg body weight (BW) intraperitoneal injection of folic acid was given in mice for inducing ARF-CRF transition (injury group; I) on day 1.

Hepatocellular carcinoma (HCC) is the most common and lethal type of primary liver cancer, frequently arising from chronic liver injury and inflammation. Despite treatment advancements, HCC prognosis remains poor, emphasizing the need for effective preventive and therapeutic strategies. This study investigates the hepatoprotective and anti-tumor effects of Hongjam, a steamed freeze-dried silkworm powder, in a diethylnitrosamine (DEN) and thioacetamide (TAA)-induced HCC mouse model.
