The purpose of this study was to focus on the underlying relationship between the hyperactivity for the peripheral monocytes and heat stroke by investigating the inflammatory oxidative activity of and the expression of superficial molecules. Peripheral blood samples were collected from 10 healthy adult volunteers. Human blood monocytes were isolated by density gradient centrifugation and sequent adherent culture. The objectives were divided into four groups: 43°C heat stress combined with lipopolysaccharide (LPS) group, 43°C heat stress group, LPS group, and control group. There were 10 cases in each group. An enzyme-linked immunosorbent assay (ELISA) test was used to measure the concentrations of supernatant inflammatory mediators (tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β) and interleukin-10 (IL-10)). After loaded by 2,7-Dichlorodi-hydrofluorescein-diacetate (DCFHDA) fluorescent probe, intracellular reactive oxygen species (ROS) levels were determined by a flow cytometry. After fluorescent microspheres incubation, the phagocytosis of monocytes was observed under a fluorescent microscope. Respectively, the flow cytometry and Western blot were used to evaluate the level of triggering receptor expressed on myeloid cells-1 (TREM-1) and Toll-like receptor-4 (TLR-4) on the monocytes. Furthermore, the mRNA expression of TREM-1 and TLR-4 was detected by real-time polymerase chain reaction (RT-PCR). The heat stress combined with LPS stimulation promoted the peripheral monocytes to produce inflammatory mediators (TNF-α, IL-1β, and IL-10) and release ROS. Otherwise, such complex strike significantly suppressed the phagocytic activity of monocytes in peripheral blood. Moreover, the expression of TREM-1, TLR-4 and CD86 was measured by the flow cytometry on peripheral monocytes which were respectively promoted by the union of heat stress and LPS. The results of Western blot and RT-PCR demonstrated the similar kinetics on these superficial molecules (TREM-1, TLR-4, and CD86) stimulated by the combination of heat stress and LPS. The underlying mechanism of the dysfunction for the peripheral monocytes may be related to the abnormal expression of superficial molecules TREM-1, TLR-4, and CD86 on the monocytes induced by heat stress and LPS.

Abstract: The correlation between allergic diseases and migraine is partially due to a better understanding of inflammatory mediators with vasoactive function that play an important role in these diseases. This study aimed to evaluate the correlation between allergic sensitization and severity of migraine.: This study was carried out on 212 patients who suffered from migraine headache in a university hospital in Mashhad, Iran. All of these patients were evaluated for allergic rhinitis (AR) by measuring the IgE level in peripheral blood and assessing the clinical symptoms of AR. Prevalence of AR in migraine patients and degree of allergic sensitization was assessed in this study.: The prevalence of AR in migraine patients was 78.30%. Total IgE levels in the peripheral blood in migraine patients with AR were found to be significantly (p<0.0001) higher than those without migraines. There was a significant difference between severity of AR (higher level of IgE) and severity of migraine attacks (p<0.0001), but there was not any significant difference between severity of AR and other factors.: We propose that inflammatory mediators play a key role in triggering migraine attacks. Thus, effective treatment of AR in migraine patients plays an important role in treatment and prevention of migraine headaches.

Objective. To observe the effects of empirical prescriptions of traditional Chinese medicine (TCM) on inflammatory mediators in pediatric asthma and to explore the underlying molecular mechanism in the treatment of asthma.Methods. A total of 182 children with asthma were randomly placed into either the TCM group (n=97) or the salbutamol and montelukast (SM) group (n=85). Patients in the TCM group were treated with a series of empirical prescriptions of TCM, while those in the SM group received salbutamol and montelukast. Both groups received their respective treatment for 12 weeks. There were 35 patients in TCM group and 34 patients in SM group providing venous blood. Real-time PCR was used to determine the mRNA expression levels of interleukin- (IL-) 10, IL-17, matrix metalloproteinase-9 (MMP-9), and transforming growth factorβ1 (TGF-β1) in peripheral blood mononuclear cells before and after treatment. Enzyme-linked immunosorbent assay was used to measure the levels of IL-10, IL-17, MMP-9, and TGF-β1 in peripheral blood before and after treatment.Results. The mRNA expression of TGF-β1 in the SM group was downregulated (P=0.00) after treatment. No significant differences were found between the TCM group and the SM group after treatment (P>0.05). In the TCM group, the levels of IL-10, IL-17, and MMP-9 significantly decreased after treatment (P=0.01, 0.04, and 0.03, resp.). In the SM group, IL-17, MMP-9, and TGF-β1 levels significantly decreased after treatment (P=0.00, 0.03, and 0.00, resp.). There was no significant difference between the two groups regarding the levels of IL-10, IL-17, TGF-β1, and MMP-9 (P>0.05). The difference of the level of IL-17 was negatively correlated with the change of C-ACT score in TCM group and SM group.Conclusion. TCM has a regulatory effect on the balance of some inflammatory mediators in pediatric asthma.
