Mechanism and Effect of Xiaoer Feike Granule on Post-infection Cough
Objective: To observe the clinical effect of Xiaoer Feike granule on cough after infection and its impact on levels of serum calcitonin gene related peptide (CGRP)
cysteinyl leukotrienes (CysLTs)
tumor necrosis factor-α (TNF-α) and interleukin-8 (IL-8). Method: One hundred and seventy patients were divided into control group (85 cases) and observation group (85 cases) by random number table. In control group
patients got montelukast sodium chewable tablets
4 mg/day for those aged below 6 years old
5 mg/day for those aged between 6 and 12 years old
1 time/day. Patients with severe cough got budesonide aerosol
0.5 mg/time
2 time/day. In addition to the therapy of control group
patients in observation were also administered with Xiaoer Feike granule
3 g/time for those aged below 4 years old
and 6 g/time for those aged between 4 and 6 years old
9 g/time
3 time/day. The course of treatment for both of the groups was 2 weeks. Cough degree for day and night and visual analogy score (VAS) were graded. And scores of traditional Chinese medicine (TCM) syndrome
such as daytime cough
nocturnal cough
thick sputum
clear dilute sputum
itchy pharynx
spiritlessness
anorexia
fatigued limbs and low voice speaking
were graded. Quality of life of cough was graded by Les Leicester Cough Questionnaire (LCQ). Levels of CGRP
CysLTs
TNF-α and IL-8 and safety evaluation were detected before and after treatment. Result: Disappearance rate of cough in observation group was 62.5%
which was higher than 39.42% in control group (χ2=8.601
P<0.01). The average extinction time of cough in observation group was shorter than that in control group (P<0.01). The total effective rate of traditional Chinese medicine in observation group was 97.5%
which higher than 83.54% in control group (χ2=9.061
P<0.01). After treatment
scores of cough degree for day and night and visual analogy score (VAS) in observation group were lower than those in control group (P<0.01). After treatment
scores of LCQ scale (physiology
psychology
society) and total scores in observation group were higher than those in control group (P<0.01). After treatment
levels of CGRP
CysLTs
TNF-α and IL-8 in observation group were lower than those in control group (P<0.01). There was no untoward effect related to Xiaoer Feike granule. Conclusion: Xiaoer Feike granule can effectively relieve cough
shorten cough course
increase the cough disappearance rate and the clinical curative effect of traditional Chinese medicine
and significantly improve the patients' quality of life. Its mechanism may be related to down-regulation of CGRP
CysLTs
TNF-α and IL-8 levels
reduction of airway inflammatory response
airway hyperresponsiveness and the cough reflex sensitivity.
