Methods: 40 male Sprague-Dawley rats were randomly divided into the normal group, SQD model group (model group), SQD+ still water group (SW group) and SQD+ Sijunzi decoction group (CM group), 10 rats each group;Grip-Strength Meter was used to measure limb grip strength;transmission electron microscope was employed to observe the ultrastructural changes of the myofibers, Image Pro 6.0 was used to measure the myonuclear numbers, cross-section area (CSA) and then their ratios (the MND sizes) were calculated, immunofluorescence assay was chosen to test the expressions of paired box gene 7 (Pax7) and myogenic differentiation antigen (MyoD). Results: Compared with those in the normal group, limb grip strength was decreased, sarcomeres were abnormal, and all the myonuclear numbers, CSA and MND sizes were reduced, but the Pax7+ cell numbers were increased, significantly, in the model and SW groups;Compared with those in the model and SW groups, limb grip strength was increased, sarcomeres were basically normal, the myonuclear number and CSA were both greater, and the Pax7+ and MyoD+ cell numbers were both increased, significantly, in the CM group. Conclusion: Sijunzi decoction might increase the myonuclear number by activating the MSCs to treat limb weakness in SQD.展开更多

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 pathwayofthebraininSDratsbygenechipmethod. RESULTS: Spleen deficiency could lead to increaseexpression 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. CONCLUSION: Sijunzi decoction and Yupingfeng powder can improve immune function of the rat through influencing the genetic expression of JAK-STAT signal pathway.展开更多
