Article Abstract
Background: NADPH oxidase 2 (NOX2) is highly expressed in injured brain tissues. We determined serum NOX2 levels of aneurysmal subarachnoid hemorrhage (aSAH) patients and further investigated correlation of serum NOX2 levels with disease severity, delayed cerebral ischemia (DCI) plus prognosis after aSAH.
Methods: Serum NOX2 levels were measured in 123 aSAH patients and 123 healthy controls. World Federation of Neurological Surgeons scale (WFNS) score and modified Fisher (mFisher) score were utilized to assess disease severity. Modified Rankin scale (mRS) score was used to evaluate the clinical prognosis at 90 days after aSAH. Relations of serum NOX2 levels to DCI and 90-day poor prognosis (mRS score of 3-6) were analyzed using multivariate analysis. Receiver operating characteristic curve (ROC) was built to evaluate the prognostic predictive capability.
Results: Serum NOX2 levels in aSAH patients, compared with healthy controls, were significantly increased, and were independently correlated with WFNS score, mFisher score and post-stroke 90-day mRS score. Patients with poor prognosis or DCI had significantly higher serum NOX2 levels than other remainders, and serum NOX2 levels independently predicted 90-day poor prognosis and DCI. Serum NOX2 had high prognosis and DCI predictive abilities, and their areas under ROC curve were similar to those of WFNS score and mFisher score.
Conclusion: Serum NOX2 levels are significantly associated with hemorrhage severity, poor 90-day prognosis and DCI in aSAH patients. Hence, complement NOX2 may serve as a potential prognostic biomarker after aSAH.

The release of synthesized zinc oxide nanoparticles (ZnO-NPs) into the environment and consequent human exposure risk brought enormous attention in recent years. In recent decades, a range of toxicological effects were highlighted on hepatotoxic risk during ZnO-NPs exposure without precise mechanistic verification. The current study employed proteomic profiling (LC-MS/MS) to unveil the interaction of ZnO-NPs with human serum proteins (protein corona) and its relevant hepatotoxic mechanisms.

Introduction: The comorbidity of myocardial ischemia reperfusion injury (MIRI) and depression (DEP) may worsen the prognosis of coronary heart disease surgery. Currently, research on medications and therapeutic mechanisms for MIRI combined with DEP is still insufficient. This study aims to explore the relationship between DEP and MIRI, and the therapeutic effects and mechanisms of Baihe Dihuang Danshen decoction (BDDSD) on DEP combined with MIRI.

Objective: Honey-fried licorice decoction (HFLD), a well-established traditional Chinese medicine, is widely used to treat atrial fibrillation (AF) in China. However, the specific cardioprotective mechanisms of HFLD in treating AF remain unclear. This study aimed to determine the efficacy of HFLD and validate the efficacy and mechanisms of action of HFLD in reducing AF susceptibility.

Ethnopharmacological Relevance: Jiedu Quyu Ziyin prescription (JP), derived from classical Chinese medicinal formulations (Shengma Biejia Tang), alleviates systemic lupus erythematosus (SLE) progression by modulating immunological derangements. The underlying mechanism by which JP regulates metabolism to retard SLE progression has not yet been fully elucidated.
Aim Of The Study: This study aims to investigate whether JP attenuates renal injury in MRL/lpr lupus-prone mice by suppressing hyperactivation of the pentose phosphate pathway (PPP) and its mediated oxidative stress.
