title: [Effects of TCM treatment according to syndrome differentiation on expressions of nuclear factor-kappaB and gamma-glutamylcysteine synthetase in rats with chronic obstructive pulmonary disease of various syndrome types].
abstract: OBJECTIVE
  To explore the mechanism of traditional Chinese medicine (TCM) treatment according to syndrome differentiation in treating chronic obstructive pulmonary disease (COPD) by observing the changes of nuclear factor-kappaB (NF-kappaB) and gamma-glutamylcysteine synthetase (gamma-GCS) expression levels in rats.
  
  
  METHODS
  COPD model was established by modified method of combining fumigation and lipopolysaccharide (LPS) intra-tracheal dripping. Model rats were treated respectively for succesive 14 days according to their syndrome, that is, Xiaoqinglong Decoction to the rats of cold-phlegm accumulation in Fei, Maxing Shigan Decoction to those of heat-phlegm accumulation in Fei, Yupingfeng Decoction to those of Fei-qi deficiency, Liujunzi Decoction to those of Pi-qi deficiency, Renshen Gejie Decoction to those of Shen qi-deficiency. Besides, model rats in the model control group received 2mL normal saline daily, and no intervention was applied in the normal control group. The expression of gamma-GCS and NF-kappaB was detected by immunochemistry before and after treatment.
  
  
  RESULTS
  Compared with that in the normal rats, the expressions of gamma-GCS and NF-kappaB in bronchial and alveolar epithelium of COPD rats before treatment were significantly higher, but the positive expression rates were lowered after treatment significantly (P<0.05).
  
  
  CONCLUSIONS
  TCM treatment according to syndrome differentiation could rectify imbalance of oxidation/anti-oxidation and alleviate inflammatory reaction in COPD rats, thus to treat COPD effectively.
