Traumatic brain injury (TBI) is a worldwide health problem, identified as a major cause of death and disability. Increasing evidence has shown that oxidative stress plays an important role in TBI pathogenesis. The antioxidant transcription factor, nuclear factor erythroid 2-related factor 2 (Nrf2), is a known mediator in protection against TBI-induced brain damage. The objective of this study was to test whether tert-butylhydroquinone (tBHQ), a novel Nrf2 activator, can protect against TBI-induced oxidative stress. ⋯ Pretreatment with tBHQ effectively attenuated markers of cerebral oxidative stress after TBI, thus supporting the testing of tBHQ as a potential neuroprotectant and adjunct therapy for TBI patients.

Rhabdomyolysis is a leading cause of acute kidney injury. The pathophysiological process involves oxidative stress and inflammation. Hydrogen-rich saline (HRS) is an antioxidant and anti-inflammatory. This study explored the protective effect of pretreatment with HRS on the development of glycerol-induced rhabdomyolysis acute kidney injury. ⋯ Pretreatment by HRS ameliorated renal dysfunction in glycerol-induced rhabdomyolysis by inhibiting oxidative stress and the inflammatory response.

Inflammatory pain is one of the most common clinical symptoms, mechanical allodynia and thermal hypersensitivities are associated with proinflammatory cytokines, and proinflammatory cytokine antagonists could alleviate the hypersensitivity. Previous studies showed that a traditional Chinese medicine ingredient, triptolide could inhibit inflammatory cytokines; however, it was still unknown whether triptolide had beneficial effects on treating inflammatory pain. ⋯ In the present study, we first reported that repeated systemic administration of triptolide could safely prevent and reverse inflammatory pain. The triptolide may serve as a new potential compound for developing safe therapeutics for patients suffering inflammatory pain.

Review Meta Analysis Comparative Study
Systematic review with meta-analysis of studies comparing intraoperative neuromonitoring of recurrent laryngeal nerves versus visualization alone during thyroidectomy.
The role of intraoperative neuromonitoring (IONM) of the recurrent laryngeal nerve (RLN) during thyroid surgery is still debatable. The aim of this meta-analysis was to evaluate the potential improvement of IONM versus RLN visualization alone (VA) in reducing the incidence of vocal cord palsy. ⋯ The current review with meta-analysis showed no statistically significant difference in the incidence of RLN palsy when using IONM versus VA during thyroidectomy. However, these results must be approached with caution, as they were mainly based on data coming from non-randomized observational studies. Further studies including high-quality multicenter, prospective, randomized trials based on strict criteria of standardization and subsequent clustered meta-analysis are required to verify the outcomes of interest.

The aim of the present study was to evaluate the efficacy of orally administered sabiporide, a selective Na(+)/H(+) exchanger inhibitor on whole body protection from severe sepsis in rats. ⋯ Administration of sabiporide improved cardiovascular performance, lessened the inflammatory response, tissue hypoperfusion and multiorgan injury, and most importantly reduced mortality.
