title: Effects of Sijunzi decoction and Yupingfeng powder on expression of janus kinase-signal transducer and activator of transcription signal pathway in the brain of spleen-deficiency model rats.
abstract: OBJECTIVE
  To observe the influence of Sijunzi decoction and Yupingfeng powder on the expression of the relevant DNAs of janus kinase (JAK)-signal transducer and activator of transcription (STAT) signal pathway of the brain in spleen-deficiency model rats.
  
  
  METHODS
  Eighty male Wistar rats of sanitary degree were divided randomly into four groups: normal group, model group, treatment group 1, treatment group 2. Besides the rats in the normal group, all the rats in other 3 groups were prepared as spleen deficiency model. The treatment group 1 were treated with Sijunzi decoction and the treatment group 2 were treated with Yupingfeng powder. After treatment for 6 weeks, perfusion was given and the brain was taken for detection of the expression of the relevant DNAs of JAK-STAT signal pathway of the brain in SD rats bygene chip method.
  
  
  RESULTS
  Spleen deficiency could lead to increase expression of JAK1, STAT1 and Interleukin 4 (IL-4) in the brain, but the decrease expression of Suppressor of cytokine signaling 1 (SOCS1), prolactin receptor (PRLR) and binding protein 3 (GATA 3). Sijunzi decoction could increase expression of STAT3, Prolactin (PRL) and GATA3, but decrease expression of JAK1, STAT, STAT4, Interleukin 10 receptor, alpha (IL10RA), Coagulation factor II (F2), PRLR, MAD homolog 3 (SMAD3) and IL-4. Yupingfeng powder could decrease expression of JAK1, STAT1, STAT4, SOCS4_ predicted, Epidermal growth factor receptor (EGFR), PRLR, High mobility group AT-hook 1 (HMGA10), IL-4.
  
  
  CONCLUSIONS
  Sijunzi decoction and Yupingfeng powder can improve immune function of the rat through influencing the genetic expression of JAK-STAT signal pathway.
