| 1 | 慢性荨麻疹发作期与缓解期患者血清IL-4、IL-10、IL-25、IFN-γ水平变化及意义显示文摘目的观察慢性荨麻疹(CU)发作期与缓解期患者血清IL-4、IL-10、IL-25、IFN-γ水平变化,并探讨其意义。方法选取69例CU患者,其中发作期34例(发作期组),缓解期35例(缓解期组),同时纳入查体健康者34例作为正常组进行空白对照,应用ELISA法检测三组血清IL-4、IL-10、IL-25、IFN-γ。结果与正常组相比,发作期组与缓解期组血清IL-4、IL-10、IL-25水平呈升高趋势(P均<0.05),血清IFN-γ水平呈降低趋势(P均<0.01)。与发作期组相比,缓解期组血清IL-10、IL-25水平呈降低趋势(P均<0.05),血清IFN-γ呈升高趋势(P<0.05),血清IL-4水平差异无统计学意义(P>0.05)。结论 CU缓解期患者血清IL-10、IL-25水平明显低于发作期,血清IFN-γ水平高于发作期;IL-4、IL-10、IL-25及IFN-γ可能参与CU发病的启动环节和风团的形成。 | 种玲玲 袁永革 徐益明 | 2015 | 山东医药2015，55，45： | 18 |
| 2 | Study on the effect and mechanism of the dysfunction of CD4^+ T cells in the disease process of chronic cardiac failure显示文摘Objective: To study the effect and mechanism of the dysfunction of CD4+ T cells in the disease process of chronic cardiac failure (CHF).Methods:According to different group technologies, 100 CHF patients were divided into the following groups: ischemia group and non-ischemia group, heart function Ⅰ-Ⅱ group and heart function Ⅲ-Ⅳ group, event group and non-event group, and 50 healthy volunteers were included in the control group. Realtime PCR was used to detect transcription factors T-bet and GATA-3 of Th1 and Th2; flow cytometry was applied to determine the ratio of Th17 and Treg cells; ELISA was employed to test cytokines IFN-γ, IL-4, IL-17 and IL-10 of peripheral blood Th1, Th2, Th17 and Treg cells, respectively; ultrasonic cardiogram was used to exploit to LVEF and LVEDd; and electrochemilu minescene immunoassay was used to examine plasma BNP. The differences of all indexes of all groups were analyzed and the correlation between CD4 T cells and clinical indexes was analyzed by Pearson correlation analysis. Results: As compared to the control group, the transcription factors T-bet and GATA-3 of Th1 and Th2, the ratio of cytokines Th17 and IFN-γ, cytokines IL-17, T-bet/GATA-3, IFN-γ/IL-4, Th17 cells/Treg cells, IL-17/IL-10 of the ischemia group and non-ischemia group, heart functionⅠ-Ⅱgroup and heart function Ⅲ-Ⅳ group, event group and non-event group were all increased significantly, while their transcription factor GATA-3 of Th2, cytokines IL4, Treg cells ratio, cytokines IL10 were decreased obviously. The differences showed statistical significance (P < 0.05). The increase or decrease of the partial CD4+ T cells of the ischemia group, heart function Ⅲ-Ⅳ group and event group was more distinctly. The results of Pearson correlation analysis showed that IFN-γ and IL-17 were significantly positively correlated with LVEDd and BNP, IL-4 and IL-10 were also significantly positively correlated with LVEF, but correlated negatively with BNP, and IL-17 was negatively correlative with LVEF. Conclusions: There was a correlation between CHF and the dysfunction of CD4+ T cells showing immune activation phenomenons of deviations from the Th1/Th2 balance towards Th1 and from the Th17/Treg balance towards Th17, which was also related to the types, severity and prognosis of the disease. | Yin-Hao Cai Zi-Jian Ma Xiu-Ying Lu En-Le He Ming-Yao You | 2016 | Asian Pacific Journal of Tropical Medicine2016，9，7： | 10 |
