[Objective] To observe the effect of serum containing Bushen prescription (BP) on inhibition of chondrocyte proliferation and nitric oxide (NO) production in chondrocyte induced by interleukin-1 (IL-1). [Methods] Four New Zealand rabbits were administered BP 2.5mL (1.15kg/L) for 3 days for the preparation of BP-containing serum. Rabbit chondrocytes were cultured in-vitro and were added with DMEM culture containing IL-1 1, 10 and 20 ?g/L to examined the inhibition concentration of IL-1 for chondrocyte proliferation. After then, BP group was added with 20 ?g/L IL-1 and various concentrations of BP-containing serum and the model group with 20 ?g/L IL-1 and various concentrations of blank serum. Alter 3-day culture, chondrocyte proliferation were dectected by thiazolyl blue colorimetry (MTT) and NO content by Griess method. [Results] The inhibition concentration of IL-1 for chondrocyte proliferation was 20 ?g/L; various concentrations of BP-containing serum could counteract chondrocyte proliferation and inhibit NO pnxluction in chondrocyte induced by IL-1. [Conclusion] BP can counteract chondrocyte proliferation directly or indirectly by the mediation of NO, which may be one of its therapeutic mechanisms in treating osteoarthritis.

Objective To investigate the retinoic acid incubation effect on proliferation of U251 cell line and effect on MAPK signal pathway. Methods ATRA solution of different concentration on the U25 1 glioma cells were incubated,the influence of ATRA on the proliferation of U25 1 cells were detected,and the proteins of MKPs and MAPK signaling pathways were detected by qRT-PCR and Western blot.Using Graph Prism 5 software for quantitative analysis of experimental results.Results Compared with control group,ATRA could effectively inhibit the proliferation of U25 1 glioma cells, in a concentration dependent manner.QRT-PCR results showed that,different concentrations of ATRA after incubation for 48 hours,the expression of MKPs mRNA changed,but the changes of MKP-5 and expression of 67LR was different,explained the main differences between the two methods of the MAPK signaling pathway was the regulation of MKP-5.Western blot results showed that the ATRA,after 48 hours of incubation,the protein MAPK pathway had changed in phosphorylation, which showed that ATRA protein in the MAPK signaling pathway through control of the degree of phosphorylation on U25 1 cell line regulation.Conclusion Retinoic acid and retinoic acid receptor play its physiological effects and regulate human glioma cell line U25 1 proliferation through different combination.Retinoic acid could not only reduce the expression of phosphorylated ERK1/2 to inhibit tumor proliferation,but also regulate three kinds of protein phosphorylation,therefore its mechanism will be more complex,at the same time that the MAPK signaling pathway plays a crucial role in tumor proliferation process.

BACKGROUND:Acupuncture point matching is little reported in the electroacupuncture for cerebral ischemia-reperfusion injury.
OBJECTIVE:To explore the influence of electroacupuncture acupoints selected by orthogonal experiment on rats with cerebral ischemia reperfusion and extracel ular signal regulated kinase (ERK) signal pathway.
METHODS:150 Sprague-Dawley rats were randomly divided into five groups:sham operation group rats were exposed the middle cerebral artery only;models of cerebral ischemia reperfusion were established in the rats in model and orthogonal groups. Then rats in the orthogonal groups 1 (Baihui (DU 20), Quchi (LI 11), Zusanli (ST 36), and Chize (LU 5)), 2 (Baihui (DU 20), Zusanli (ST 36), Chize (LU 5), and Sanyinjiao (SP 6)) and 3 (Hegu (LI 4), Zusanli (ST 36), Chize (LU 5) and Sanyinjiao (SP 6)) were given electroacupuncture at acupoints selected by orthogonal experiment, respectively.
RESULTS AND CONCLUSION:Compared with the model group, in al orthogonal groups, the neurological function deficit scores were decreased, infarct volume was smal er, the number of microvessel density in the ischemia region and the p-ERK expression level in the cortex and hippocampal CA1 region of ischemic hemisphere were increased, and significant changes were found in the orthogonal group 3. These findings indicate that electroacupuncture at points of Hegu (LI 4), Zusanli (ST 36), Chize (LU 5) and Sanyinjiao (SP 6) selected by orthogonal experiment can significantly reduce the infarct volume of cerebral ischemia-reperfusion injury in rats possibly by regulating the ERK signaling pathway.

To study which subgroup of bone marrow derived cells formed myofibroblasts and the mechanism that transforming growth factor β1 (TGFβ1) regulates the formation of bone marrow derived macrophages into myofibroblasts during renal fibrosis.Chimeric mice were generated by lethally irradiation of C57 mice followed by transfusion of green fluorescent protein (GFP) labeled bone marrow cells.Complete marrow reconstitution was developed until 12 weeks after transplantation.The mice were randomly divided into Sham operation group,unilateral ureteral obstruction (UUO) 3 days group,UUO5 days group,UUO7 days group and UUO7 with TGFβ1 treatment group.Each group had four mice.Flow cytometry was used to evaluate cell components.Compared with Sham operation group the proportions of GFP + CD+14 oα-smooth muscle actin(α-SMA) + cells,GFP + CD+44 CD+105 α-SMA+ cells and GFP+ F4/80+ α-SMA+ cells in each UUO group were progressively increased and the transformation rate in UUO7 day group was the highest.The GFP+ F4/80 + α-SMA+ cells accounted for the largest population.TGFβ1 promoted the transformation of bone marrow derived macrophages into myofibroblasts.Compared with Sham operation group or UUO7 day group,the proportion of GFP+ F4/80+ α-SMA+ cells increased in UUO7 day TGFβ1 treatment group.Compared with Sham operation group (or UUO7 days group) the protein expressions of F4/80,oα-SMA,Collagen Ⅰ increased in UUO7 with TGFβ1 group.Bone marrow derived macrophages are considered as the main type of myofibroblast precursors during the development of renal fibrosis.TGFβ1 regulates the transformation of bone marrow-derived macrophages into myofibroblasts.This process contributes to progressive renal fibrosis and deterioration of renal function.

Objective Intestinal ischemia-reperfusion (I-R) is a critical and triggering event in the development of distal organ dysfunction,frequently involving the lungs.In this study we investigated the effects of edaravone on the prevention of lung injury induced by intestinal I-R in rats.Methods Eighteen male SD rats were randomly divided into 3 groups: Sham operation group (group Sham),I-R group (group IR) and edaravone group (group E).After injecting 6 mg of edaravone or the same volume of 0.9% sodium chloride,the anterior mesenteric artery was clamped with a noninvasive microvascular clip for 120 min and then reperfusion for 120 min.Sham-operated animals underwent the same surgical procedures without clamping.Lung tissues were collected for pathology tested by HE dyed,blood as collected for the analysis of TNF-α and IL-6 concentration by ELISA,small lung tissues were collected for the analysis of lung myeloperoxidase (MPO) activity and malonialdehyde (MDA) concentration.Results Compared with group Sham,the alveolar epithelial cells in group IR was widespread edema,inflammatory cell infiltration,atectasis,disruption of alveolar,and pulmonary capillary hemorrhage.The pathological changes of lung tissue in group E were significantly improved compared with those in group IR,and that of alveolar inflammatory exudate was decreased.Pathological scoring of group E (2.1±0.7),which was significantly lower than that of group IR (5.7±1.1) and group sham (1.5±0.2) score (P<0.05),so the concentration of TNF-α,IL-6,MPO activity and MDA concentration of group E were less than those of group IR (P<0.01).Conclusion Edaravone ameliorated the lung injury induced by intestinal I-R.
