The correlation between FeNO and nNO in allergic rhinitis and bronchial asthma

This study aimed to evaluate the correlation between fractional exhaled nitric oxide (FeNO) and nasal nitric oxide (nNO) in allergic rhinitis (AR) and patients with or without bronchial asthma (BA).A total of 90 patients who were diagnosed with persistent AR (AR group, n = 30), BA (BA group, n = 30), or allergic rhinitis with bronchial asthma (AR-BA) (AR-BA group, n = 30), were enrolled in this study, along with 30 healthy adult volunteers (control group, n = 30). The participants were further divided into 2 groups based on the results of a skin-prick test (SPT): a highly atopic group (SPT = 3+ and above) and a moderately atopic group (SPT = 2+ and below). All participants underwent FeNO and nNO measurement, an absolute blood eosinophil count, total serum immunoglobulin measurement, and horizontal baseline lung capacity determination.The results showed that the FeNO levels in the 3 observation groups were significantly higher than those in the control group (P < .01), and in the BA group they were significantly higher than in the AR-BA group (P < .01). The levels of nNO in both the AR group and the AR-BA group were higher than those in the control group and the BA group (P < .01), but there was no significant difference between the AR group and the AR-BA group (P > .05). The levels of nNO in the BA group were also significantly different from those in the control group (P < .01).FeNO and nNO are positively correlated with the degree of AR in patients with BA; therefore, nNO levels can be used as an inflammatory marker of AR in patients with BA. FeNO can also be used as an inflammatory marker of AR in patients complicated with BA as a warning indicator of asthma.     

金水宝片联合异丙托溴铵治疗慢性支气管炎的临床研究

目的 探讨金水宝片联合异丙托溴铵治疗慢性支气管炎的临床疗效。方法 选取2021年1月—2023年11月内蒙古医科大学附属医院收治的慢性支气管炎患者106例,随机分为对照组（53例）和治疗组（53例）。对照组雾化吸入吸入用异丙托溴铵溶液,2 mL/次,2次/d。在此基础上,治疗组口服金水宝片,4片/次,3次/d。两组患者治疗3个月。观察两组患者临床疗效,比较治疗前后两组患者主症消失时间,肺功能指标用力肺活量（FVC）、呼气峰值流量（PEF）和最大呼气中段流量（MMEF）水平,外周血T淋巴细胞亚群水平,及血清嗜酸性粒细胞趋化因子（Eotaxin）、肿瘤坏死因子-α（TNF-α）、转化生长因子-β1（TGF-β1）和内皮素-1（ET-1）水平。结果 治疗后,治疗组临床总有效率为96.23%,明显高于对照组的84.91%（P＜0.05）。治疗后,治疗组各项主症的消失时间均明显短于对照组（P＜0.05）。治疗后,两组患者FVC、PEF、MMEF、CD3^＋、CD4^＋和CD4^＋/CD8^＋水平明显高于治疗前,而CD8^＋、Eotaxin、TNF-α、TGF-β1和ET-1水平显著低于治疗前（P＜0.05）,且治疗后治疗组患者肺功能指标、外周血T淋巴细胞亚群水平和血清因子水平明显好于对照组（P＜0.05）。结论 金水宝片联合异丙托溴铵治疗慢性支气管炎可加速患者症状缓解,提高肺功能及临床疗效,改善免疫功能及炎症状态。     

中西医结合治疗支气管哮喘的临床观察

为了探讨支气管哮喘的治疗方法,将本病患者87例随机分为中西医结合治疗组46例和西药对照组41例,治疗组用中西医结合方法治疗,对照组单纯用西医方法治疗;观察两组症状、体征治疗前后的变化.治疗组总有效率86.96%,对照组总有效率73.81%,两组疗效有显著性差异(P＜0.05);肺功能改善治疗组明显优于对照组.应用中西医结合方法治疗支气管哮喘的疗效明显优于单用西医治疗.     

乙酰半胱氨酸联合氨茶碱治疗慢性喘息性支气管炎急性发作的临床研究

目的 分析乙酰半胱氨酸溶液联合氨茶碱治疗慢性喘息性支气管炎急性发作的疗效。方法 选取2021年12月—2023年6月西安市第八医院收治的156例慢性喘息性支气管炎急性发作患者,按随机数字表法分为对照组和治疗组,每组各78例。对照组静脉滴注氨茶碱注射液,0.25 g溶于5%葡萄糖溶液250 mL中,3次/d。治疗组对照组治疗基础上雾化吸入吸入用乙酰半胱氨酸溶液,3 mL/次,2次/d。两组疗程7 d。观察两组的临床疗效和主要表现缓解时间,比较两组治疗前后肺功能指标、呼出气一氧化氮（FeNO）、诱导痰中嗜酸性粒细胞（EOS）比例、血清C反应蛋白（CRP）、内皮素-1（ET-1）、白细胞介素-8（IL-8）的变化情况。结果 治疗后,治疗组总有效率是96.15%,显著高于对照组的87.18%（P＜0.05）。治疗后,治疗组喘息、咳痰、咳嗽、哮鸣音缓解时间显著短于治疗组（P＜0.05）。治疗后,两组用力肺活量（FVC）、用力呼气中期流速（MMEF）、第1秒用力呼气量（FEV₁）、深吸气量与肺总量比值（IC/TLC）均较同组治疗前显著升高（P＜0.05）;治疗后,治疗组肺功能指标改善优于对照组（P＜0.05）。治疗后,两组FeNO、诱导痰中EOS比例和血清CRP、ET-1、IL-8水平均显著下降（P＜0.05）;治疗后,治疗组FeNO、诱导痰中EOS比例和血清CRP、ET-1、IL-8水平改善优于对照组（P＜0.05）。结论 乙酰半胱氨酸溶液联合氨茶碱治疗慢性喘息性支气管炎急性发作的效果及安全性较佳,能快速缓解患者主要临床表现,抑制气道炎症及机体炎性损伤,降低呼吸道阻力,促进肺功能改善,值得推广应用。

Continuous glucose monitoring in youth with cystic fibrosis treated with lumacaftor-ivacaftor

Background

The effects of lumacaftor-ivacaftor therapy on glycemia have not been thoroughly investigated. Continuous glucose monitoring (CGM) provides detailed information about glycemic patterns and detects glucose abnormalities earlier than traditional screening tools for diabetes.
