ABSTRACT
<p><b>Background</b>Several studies have reported that mindfulness meditation has a potential effect in controlling headaches, such as migraine and tension-type headache; however, its role remains controversial. This review assessed the evidence regarding the effects of mindfulness meditation for primary headache pain.</p><p><b>Methods</b>Only English databases (PubMed, Cochrane Central Register of Controlled Trials [the Cochrane Library], PsycINFO, Psychology and behavioral science collection, PsyArticles, Web of Science, and Scopus) were searched from their inception to November 2016 with the keywords ("meditation" or "mindfulness" or "vipassana" or "dzogchen" or "zen" or "integrative body-mind training" or "IBMT" or "mindfulness-based stress reduction" or "MBSR" or "mindfulness-based cognitive therapy" or "MBCT" and "Headache" or "Head pain" or "Cephalodynia" or "Cephalalgia" or "Hemicrania" or "Migraine"). Titles, abstracts, and full-text articles were screened against study inclusion criteria: controlled trials of structured meditation programs for adult patients with primary headache pain. The quality of studies included in the meta-analysis was assessed with the Yates Quality Rating Scale. The meta-analysis was conducted with Revman 5.3.</p><p><b>Results</b>Ten randomized controlled trials and one controlled clinical trial with a combined study population of 315 patients were included in the study. When compared to control group data, mindfulness meditation induced significant improvement in pain intensity (standardized mean difference, -0.89; 95% confidence interval, -1.63 to -0.15; P = 0.02) and headache frequency (-0.67; -1.24 to -0.10; P = 0.02). In a subgroup analysis of different meditation forms, mindfulness-based stress reduction displayed a significant positive influence on pain intensity (P < 0.000). Moreover, 8-week intervention had a significant positive effect (P < 0.000).</p><p><b>Conclusions</b>Mindfulness meditation may reduce pain intensity and is a promising treatment option for patients. Clinicians may consider mindfulness meditation as a viable complementary and alternative medical option for primary headache.</p>

<p><b>OBJECTIVE</b>To investigate the effect of suramin on inflammatory response in pulmonary tissue and peripheral blood in septic mice.</p><p><b>METHODS</b>Twenty-four male C57BL/6 mice were randomly divided into two groups, and suramin(5 mg/kg) or normal saline was intravenously injected 30 min before LPS(5 mg/kg)infusion, respectively. The contents of TNF-α and IL-6 in pulmonary tissue and peripheral blood were detected by ELISA. Suramin or saline-pretreated human mononuclear THP-1 cells were treated with 100 ng/mL LPS in vitro. The expression of TNF-α and IL-6 mRNA and the activity of NF-κB were analyzed by quantitative PCR and Western blotting at different time points after LPS treatment, respectively.</p><p><b>RESULTS</b>Compared with the saline group, the TNF-α and IL-6 levels in pulmonary tissue and peripheral blood were significantly reduced in suramin group at 24 h after LPS treatment(all P<0.01); while there was no significant difference at 72 h between two groups(all P>0.05). The expression of TNF-α, IL-6 mRNA and the activity of NF-κB was decreased in suramin group at different time points after LPS treatment.</p><p><b>CONCLUSION</b>Suramin can protect LPS-induced acute lung injury through down-regulation of systemic and pulmonary pro-inflammatory factors, which may be associated with the inhibition of NF-κB activity.</p>
