They were treated with XYA and Salb utamol aerosol (SA) respectively by spray inhalation once a day for seven days a s one therapeutic course to observe the antiasthmatic effect of the treatment. Changes of lung function and the levels of tumor necrosis factor α (TNF-α) , interleukine-2 receptor (IL-2R) and interleukine-8 (IL-8) in serum and sputum were observed before and after treatment using enzyme linked immunos orbent assay (ELISA). Levels of TNF-α, IL-2R andIL-8 in the sputum of part of the patients in the treatment group were also observed.Results: In the treated group, 6 patients had the asthma clinica lly controlled after treatment, 12 were markedly alleviated, 9 alleviated and 3 remained unchanged, while in the control group, the respective numbers were 4, 6 , 15 and 5. The controlled-markedly effective rate of XYA was 60.0%, which wa s significantly better than that of SA (33.3%, P <0.05). The one second forc ed expiratory volume percent (FEV1%) and peek expiratory flow rate (PEFR) improv ed significantly and the levels of TNF-α, IL-2R and IL-8 in serum decr eased noticeably in both groups after treatment ( P <0.05 or P <0.01), but the improvement in the treated group was more significant as compared with tho se in the control group ( P <0.05). The levels of TNF-α, IL-2R and IL -8 in sputum considerably lowered also after XYA treatment ( P <0.01).Conclusion: XYA could regulate the related cytokines in patient s with mild or moderate bronchial asthma, and reduce the releasing of inflammato ry factors, which is consistent with the improvement of lung functions, so as to ease the airway inflammation chiefly exhibited as cell infiltration in bron chi.展开更多

The battles between Mtb and macrophages have been constant since ancient times. Triggered upon Mtb infection, multiple cellular pathways in macrophages are activated to initiate a tailored immune response toward the invading pathogen and regulate the cellular fates of the host as well. Toll-like receptors （TLRs） expressed on macrophages can recognize pathopatterns （PAMPs） on Mtb and mediate the production of immune-regulatory cytokines such as tumor necrosis factor （TNF） and type I Interferons （IFNs）. In addition, Vitamin D receptor （VDR） and Vitamin D-1- hydroxylase are up-regulated in Mtb-infected macrophages, by which Vitamin D participates in innate immune respon- ses. The signaling pathways that involve TNF, type I IFNs and Vitamin D are inter-connected, which play critical roles in the regulation of necroptosis, apoptosis, and autophagy of the infected macrophages. This review article summarizes cur- rent knowledge about the interactions between Mtb and macrophages, focusing on cellular fates of the Mtb-infected macrophages and the regulatory molecules and cellular pathways involved in those processes.展开更多
