MiR-133b Promotes neurite outgrowth by targeting RhoA expression.
MicroRNA-133b (miR-133b) has been shown to play a critical role in spinal cord regeneration. The aim of this study was to investigate the cellular role of miR-133b in neural cells. ⋯ In summary, our study suggested that miR-133b regulated neurite outgrowth via ERK1/2 and PI3K/Akt signaling pathway by RhoA suppression.

ReviewGrowth and differentiation factor-5 contributes to the structural and functional maintenance of the intervertebral disc.
Intervertebral disc degeneration (IDD) is a widely recognized contributor to low back pain (LBP). The Prevention or reversal of IDD is a potential treatment for LBP. Unfortunately, current treatments for IDD are aimed at relieving symptoms rather than regenerating disc structure or function. ⋯ The effects of GDF-5 on IVD regeneration and on MSC differentiation are also discussed. GDF-5 plays a crucial role in the pathogenesis of IDD and is a promising therapeutic agent for IDD. Additionally, stem cell transplantation has been shown to be a promising biological therapy for IDD.

Genetic association of MiR-146a with multiple sclerosis susceptibility in the Chinese population.
miR-146a polymorphisms have been involved in susceptibility to multiple diseases. The aim of the present study was to analyze the potential association between two functional miR-146a polymorphisms (rs2910164 and rs57095329) and multiple sclerosis (MS) in the Han Chinese population. ⋯ Our results provide evidence that rs2910164 may play a role in MS susceptibility in females. The rs2910164 G>C variation may affect the expression of miR-146a and the release of proinflammatory cytokines.

Serum Procalcitonin Level and Mortality Risk in Critically ill Patients with Ventilator-Associated Pneumonia.
The prognostic role of serum procalcitonin level in critically ill patients with ventilator-associated pneumonia was unclear. The aim of our study was to investigate the relationship between serum procalcitonin level and mortality risk in critically ill patients with ventilator-associated pneumonia. ⋯ High serum procalcitonin level is an independent prognostic biomarker of mortality risk in critically ill patients with ventilator-associated pneumonia, and it's a promising biomarker of prognosis in critically ill patients.

Hydrogen Sulfide Inhalation Improves Neurological Outcome via NF-κB-Mediated Inflammatory Pathway in a Rat Model of Cardiac Arrest and Resuscitation.
The effects of H2S on cerebral inflammatory reaction after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) remain poorly understood. In this study, we investigated the effects of exogenous 40 ppm and 80 ppm H2S gas on inflammatory reaction and neurological outcome after CA/CPR. ⋯ These results indicated that inhalation of H2S protected against brain injury after CA/CPR. The mechanisms underlying protective effects of H2S were associated with the inhibition of CA/ CPR-induced inflammation reactions by reducing IL-1β, IL-6 and TNF-α, and concomitantly inhibiting the activation and infiltration of neutrophils. The beneficial effects of H2S might be mediated by downregulation of NF-κB and the downstream proinflammatory signaling pathway.
