ABSTRACT
Objective:To observe the role of Huaiqihuang Granules (HQ) in the long-term management of bronchial asthma in young children, and the effective effect on concomitant rhinitis.Methods:A prospective real-world multicenter study was conducted in children aged 2-5 years with asthma diagnosed in the outpatient department (from April 2016 to March 2019)who received either inhaled corticosteroid (ICS)/leukotriene receptor antagonist (LTRA)(control group); inhaled ICS/LTRA plus HQ(combination group), or HQ alone(HQ group). All patients were followed up at week 4, 8, 12 after treatment. The number of days with asthma symptoms, the frequency of severe asthma attacks, the level of asthma control, and the days with rhinitis symptoms in the last 4 weeks were recorded. Differences before and after treatment, and those among groups after treatment were compared using Kruskal- Wallis H test or Wilcoxon rank-sum test. Results:A total of 2 234 eligible patients were recruited, and 2 147 cases completed followed-up visits, including 477, 1 374 and 296 cases in the control group, combination group, and HQ group, respectively. After the treatment, all 3 groups showed significant declines in the days with asthma symptoms, frequency of severe asthma attack and the days with rhinitis symptoms (all P<0.01), and the rate of well-controlled asthma increased significantly ( P<0.01). It lasted until the end of follow-up. Among groups, patients in the combination group showed significantly less days of asthma symptoms than those of the other 2 group at week 8 and 12[0(0, 0.9) d vs.0(0, 0.3) d, P<0.05; 0(0, 0.1) d vs. 0(0, 1.0) d, P<0.01]. Patients in the combination group and HQ group showed a significantly lower rate of severe asthma attacks than that of the control group at week 12 [0(0, 1), 0(0, 1), 0(0, 2), all P<0.05]. The well-controlled rate of asthma in the combination group was significantly higher than that of the control group and HQ group at week 8 and 12 (89.6% vs. 85.9% vs.82.1%, H=15.28; 90.9% vs. 84.1% vs. 81.8%, χ2=29.32, all P<0.01). Conclusions:HQ can significantly alleviate symptoms of asthma and rhinitis, severe attack of asthma, and increase the control rate of asthma when used as an additional treatment or used alone.
ABSTRACT
ObjectivesTo explore the clinical manifestations and treatment ofMycoplasma pneumoniae pneumonia (MPP) combined with venous thrombosis.MethodsThe clinical manifestations and treatment of MPP combined with venous thrombosis were retrospectively analyzed.ResultsTwo male patients were 5 years 2 months and 3 years 6 months old respec-tively. After treatment with erythromycin, corticosteroids, immunoglobulin, bronchoalveolar lavage and thrombolytic, both cases were cured. Conclusions It is necessary to pay attention to the occurrence of thrombosis in MPP. Early diagnosis and treatment of thrombosis is very important for the prognosis. The prevention of thrombosis needs to be further studied.
ABSTRACT
Objective To investigate the effects of leukotriene in children with respiratory syncytial (RSV)viral bronchiolitis.Methods The blood and sputum levels of Ieukotriene were detected in 33 cases diagnosed RSV bronchiolitis and 12 cases which were diagnosed pneumonia without RSV infection.Thirty-three cases of bronchiolitis were devided into mild-moderate group(n =22)and severe group(n =11)according to the lowell score.Results The blood and sputum levels of leukotriene in mild-moderate group,severe group,and pneumonia group were(76.96 ± 28.19)pg/ml,(103.53 ± 16.85)pg/ml,(18.14.± 7.49)pg/ml;(31.83 ± 19.14)pg/ml,(67.11 ± 15.11)pg/ml,(6.81 ± 2.90)pg/ml in acute period,and(36.04 ±16.38)pg/ml,(52.27 ± 17.03)pg/m l,(18.14 ± 7.49)pg/ml of serum in recovery period.There were significant differences among three groups(F =48.09,P ＜ 0.001 ; F =15.50,P ＜ 0.001 ; F =44.43,P ＜0.001).After treatment,the blood levels of leukotriene were significantly decreased,but were still higher than that of pneumonia group(P ＜ 0.05).Conclusion The blood and sputum levels of leukotriene increase in children with RSV bronchiolitis,which is related with the severity of bronchiolitis.
