title: [Clinical study on treatment of chronic bronchitis by tracheitis plaster].
abstract: OBJECTIVE
  To study the clinical effect and mechanism of Tracheitis Plaster (TP) in treating chronic bronchitis.
  
  
  METHODS
  TP is consisted of ephedra, almond, pinellia tuber, earthworm and white mustard seed. Patients were randomly divided into two groups, 59 patients in the treated group were treated with TP sticking on acupoints Dingchuan, Dashu, Fengmen, Feishu and Xinshu at back along both sides of thoracic vertebrae 1-6 and the 25 patients in the control group were treated with intramuscular injection of Siqikang. The times of treatment for both groups were 20. Clinical symptoms, X-ray chest film, level of immunoglobulin and T-lymphocyte subsets were recorded before and after treatment, and follow-up were carried out 0.5-1 year later.
  
  
  RESULTS
  The clinical total effective rate was 93.2% and the X-ray improvement rate was 40.7% in the treated group, while in the control group, 80.0% and 20.0% respectively. Half and 1 year follow-up studies showed the total effective rate in the treated group was 91.5% and 89.8% respectively, which was significantly higher than that in the control group (80.0% and 76.0%) respectively (P < 0.05). The improvement in levels of IgG and CD8 in the treated group was also superior to those in the control group (P < 0.05).
  
  
  CONCLUSIONS
  TP is a highly effective transcutaneous absorbent with promising long-term effect, it could regulate the immune function.
