Increasing evidence demonstrate N-acetylcysteine amide (NACA) provides neuroprotection and attenuated oxidative stress in rats following traumatic brain injury (TBI). The nuclear factor erythroid 2-related factor 2 (Nrf2)-antioxidant response element (ARE) signal pathway is activated after TBI and provides a protective effect against TBI. However, the function and mechanism of NACA in mice after TBI remain unknown. This study was to evaluate the neuroprotection of NACA and the potential action of the Nrf2-ARE pathway in a weight-drop mouse model of TBI. ⋯ Our study reveals that NACA potentially provides neuroprotection via the activation of the Nrf2-ARE signaling pathway after TBI in mice.

Review Meta Analysis Comparative Study
Intra-articular platelet-rich plasma versus hyaluronic acid in the treatment of knee osteoarthritis: a meta-analysis.
Platelet-rich plasma (PRP) and hyaluronic acid (HA) have been increasingly used in recent years to treat knee osteoarthritis (OA). However, whether PRP is superior to HA is controversial. ⋯ The intra-articular injection of PRP was not obviously superior to HA in knee OA. Due to the limited quality and data of the evidence currently available, more high-quality randomized controlled trials are required.

Meta Analysis
Effect and safety of antithrombotic therapies for secondary prevention after acute coronary syndrome: a network meta-analysis.
Dual antiplatelet therapy is a standard protocol for secondary prevention after acute coronary syndrome, but despite a variety of new dual antithrombotic strategies, there is a dearth of studies evaluating the effects and safety of some popular therapies. This study used a network meta-analysis to compare the efficacy and safety of all available antithrombotic therapies. ⋯ We concluded the following from our study: 1) an aspirin + new P2Y12 inhibitor/ clopidogrel conversion treatment strategy was not inferior to aspirin + new P2Y12 inhibitor; 2) compared with aspirin + clopidogrel, the conversion strategy may further reduce the risk of myocardial infarction without increasing the risk of bleeding; and 3) compared with aspirin + clopidogrel, treatment with aspirin + new P2Y12 inhibitors may result in reduced risk of death.

Review
Benralizumab in the treatment of severe asthma: design, development and potential place in therapy.
Asthma is a widespread and heterogeneous inflammatory disease of the airways, which is characterized by several different phenotypes and endotypes. In particular, eosinophilic airway inflammation is a common pathologic trait of both allergic and nonallergic asthma. The key cytokine responsible for maturation, activation, recruitment, and survival of eosinophils is interleukin (IL)-5, which is mainly produced by T helper 2 (Th2) lymphocytes and group 2 innate lymphoid cells. ⋯ Among these new treatments, anti-IL-5 monoclonal antibodies such as mepolizumab and reslizumab have been developed and clinically evaluated. Furthermore, benralizumab is currently the only available biologic drug that specifically binds to the IL-5 receptor, thus preventing the interaction with its ligand and the consequent pro-inflammatory effects. The effectiveness of benralizumab in improving severe eosinophilic asthma has been well-documented by many randomized controlled trials.

The neuroprotective effects of Baicalin have been confirmed in several central nervous system (CNS) diseases. However, its possible effect on traumatic brain injury (TBI) model is still not clear. The present study is aimed to investigate the role and the underling mechanisms of 7-D-glucuronic acid-5,6-dihydroxyflavone (Baicalin) on TBI model. ⋯ This study demonstrates that Baicalin provides a neuroprotective effect in TBI mice model via activating the Akt/Nrf2 pathway.
