小儿平喘方治疗小儿支气管哮喘急性发作患儿的临床效果及对肺功能的影响

目的 探究小儿支气管哮喘急性发作患儿应用小儿平喘方治疗的临床效果及对肺功能的影响。方法 选取2020年1月至2021年12月苏州市中西医结合医院的82例小儿支气管哮喘急性发作患儿作为研究对象,采取随机数字表法将其分为对照组(41例)和观察组(41例)。对照组患儿采用布地奈德混悬液治疗,观察组患儿采用布地奈德混悬液+小儿平喘方治疗。比较两组患儿的临床疗效、临床症状评分、肺功能、免疫功能相关指标、血清炎症因子以及不良反应。结果 观察组患儿的治疗总有效率高于对照组,差异有统计学意义(P<0.05);观察组患儿治疗后的喘息、咳嗽、哮鸣音等临床症状评分低于对照组,差异有统计学意义(P<0.05);观察组患儿治疗后的第一秒用力呼气容积(FEV1)、一秒率(FEV₁/FVC)、最大呼吸流量(PEF)水平高于对照组,差异有统计学意义(P<0.05);观察组患儿治疗后的CD3⁺、CD4⁺、CD4⁺/CD8⁺高于对照组,差异有统计学意义(P<0.05);观察组患儿治疗后的肿...     

类风湿关节炎患者血清巨噬细胞移动抑制因子白细胞介素-17及-23表达与合并动脉粥样硬化的相关性研究

目的 通过颈部彩色多普勒超声检测类风湿关节炎(RA)患者合并动脉粥样硬化情况,检测血清巨噬细胞移动抑制因子(MIF)及白细胞介素(IL)-17、IL-23水平,分析它们之间的相关性及在RA致动脉粥样硬化中的作用.方法 收集69例RA患者,根据颈部血管彩色多普勒超声结果,分为合并动脉粥样硬化组36例及无动脉粥样硬化组33例,并设64名健康者为健康对照组.采用酶联免疫吸附试 验(ELISA)法检测3组血清MIF、IL-17及IL-23水平.采用t检验、方差分析进行统计分析,相关性分析采用Pearson相关分析和Logistic回归分析.结果 合并动脉粥样硬化组MIF水平明显高于无动脉粥样硬化组及健康对照组(3组分别为15.2±1.7,13.8±2.2,8.0±2.9,P<0.05),且与颈动脉内膜中层厚度(IMT)值(r=0.271,P=0.036)、斑块大小(r=0.291,P=0.024)、IL-17(r=0.328,P=0.007)及IL-23(r=0.316,P=0.010)水平呈正相关;合并动脉粥样硬化组IL-17和IL-23水平高于健康对照组(2.8±2.0和2.0±0.8,449±174和341±113),但与无动脉粥样硬化组比较差异无统计学意义.Logistic回归分析显示RA患者MIF水平与动脉粥样硬化的发生呈正相关.结论 RA合并动脉粥样硬化患者血清MIF水平显著升高,且与IL-17、IL-23表达密切相关,血清MIF水平升高可作为RA患者发生动脉粥样硬化的预测指标.

Abstract：

objective To detect the serum macrophage migration inhibitory factor(MIF)and interlbukin (IL)-17,IL-23 levels in rheumatoid arthritis patients with atherosclerosis and to analyze the association between them and their role in the pathogenesis of atherosclerosis in rheumatoid arthritis patients.Methods Total of 69 patients with RA were divided into atherosclerosis group(AS group)and those without atherosclerosis group(NAS group)according to neck vascular ultrasonography.Sixty-four healthy controls(the control group)were also enrolled into this study.MIF and IL-17,IL-23 levels were determined bv ELISA assay.The t test of two independent-samples and One-way ANOVA were used to compare the levels of MIF.IL-17 and IL-23 in different groups of patients and healthy individuals.The correlation between diffrent paramenters was assesed by Pearson's coefficient of correlation and Logistic regression.Results The serum MIF level in the AS group was significantly higher than that in the NAS group and healthy controls(15.2±1.7,13.8±2.2,8.0±2.9,P<0.05),and there were significant correlations between the serum MIF concentration,carotid intima-media thickness(IMT)(r=0.271,P=0.036).the size of atherosclerotic plaques(r=0.291,P=0.024),the serum level of IL-17(r=0.328,P=0.007)and IL-23(r=0.316,p=0.010).The serum IL-17 and IL-23 level in the AS group was higher than healthy controls(2.8±2.0 vs 2.0±0.8,449±174 vs 341±113),while there were no significant differences between AS group and NAS group.The serum MIF level in RA patients was positively correlated with atherosclerosis according to Logistic regression analysis.Conclusion The serum MIF level in RA patients with AS is significantly higher than that in NAS group and healthy controls,and it may be related with the serum level of IL-17 and IL-23.The elevated serum MIF level may be a predictor for atherosclerosis in patients with rheumatoid arthritis.
