Objective To explore the effect of nitric oxide(NO) on pulmonary tumor necrosis factor?(TNF?) in murine acute necrotizing pancreatitis(ANP). Method Ninety-six SD rats were randomized into four groups:normal control group, ANP group, L-Arginine(L-Arg) pretreatment group and L-NAME pretreatment group (n=24 for each group). The protein content of bronchoalveolar lavage fluids(BALF), the myeloperoxidase(MPO) of lung tissue and TNF? produced by alveolar macrophages were evaluated. The expression of TNF? mRNA was measured. ResultMPO and protein of BALF reached a peak level at 12nd hr (10.78?0.58U/g for MPO and 2011?106?g/ml for protein content respectively).TNF? peaked on the sixth hour(1624?149)pg/ml. The expression of AM TNF?mRNA also peaked on the sixth hour (1.127?0.069) along with an increase of TNF? mRNA. A similar tendency was seen in L-Arg and L-NAME pretreatment groups, with changes being statistically different in the three groups when compared with that of normal control group(P

Objective: To observe the effect of elk antlers ethanolic fluidextract on behavior and immune function of aging model mice. Methods: ICR mice were randomly divided into 4 groups: Normal control group (NG), model control group (MG), low-dose drug treatment group (LG,2g/kg) and high-dose drug treatment group (HG,4g/kg). Mice were given subcutaneous injection of D-galactose (D-gal) at 120 mg/kg to induce subacute aging model. At the same time LG and HG were respectively administrated corresponding concentration of elk antlers ethanolic extract. Six weeks later, the learning and memory test was run by Y-maze. Then single agar immunodiffusion method was used to detect IgG level in serum, and spleen lymphocyte transforming stimulation index (SI) was determined by methyl thiazolyl tetrazolium(MTT) method as well as the concentration of Interleukin-2(IL-2) and interferon-gama(IFN-?) in serum were determined by ELISA method. Results: The memory and immune function of aging mice declined signif icantly. Elk antlers ethanolic fluidextract could obviously improve memory ability, increase the IgG level, raise the lymphocyte transforming SI, and elevate the concentration of IL-2 and IFN-? in model mice induced by D-gal. Conclusions: Elk antlers ethanolic extract could improve behavior and immune function of aging mice to delay aging process.

Objective To detect the levels of IL-1, IL-6,TNF-αand IFN-γin serum and colon tissue of rat mod-els of ulcerative colitis with spleen and kidney Yang deficiency, and to explore their roles in the pathogenesis of ulcerative colitis ( UC) .Methods The rat model of ulcerative colitis with Yang deficiency of spleen and kidney was induced by perfusion of rhubarb decoction plus intramuscular injection of hydrocortisone and combined with TNBS (2,4,6-trinitro-benzenesulfonic acid) and ethanol enema.Sixty SPF wistar rats ( body weight 180 ±10 g, male:female=1:1) were ran-domly divided into blank control group, UC model with spleen kidney Yang deficiency for 7 days, 14 days and 21 days groups, respectively.The levels of IL-1, IL-6, TNF-αand IFN-γin serum and colon tissue were detected by ELISA.Re-sults Compared with the blank group, the levels of IL-1, IL-6, TNF-αand IFN-γin serum and colon tissue of rat UC model group with spleen kidney Yang deficiency were greatly increased (P<0.05), especially evidently increased in the model group at 21 days.Conclusions The pro-inflammatory cytokines IL-1, IL-6, TNF-αand IFN-γplay an important role in the pathogenesis of ulcerative colitis with syndrome of spleen and kidney Yang deficiency.

Objective To study the effects of modified Danggui Beimu Kushen Pills on the expressions of TLR2, TLR4, TLR6, TRAF6 and MyD88 in tumor tissues on MFC gastric cancer bearing mice; To discuss relevant mechanism of action. Methods MFC gastric cancer bearing mice were employed to perform anti-tumor experiment in vivo in this study. A total of eligible 48 mice were randomly divided into model group, DDP positive control group, modified Danggui Beimu Kushen Pills high-dose and low-dose groups, modified Danggui Beimu Kushen Pills high-dose and low-dose combined with DDP groups. The treatment was conducted once a day, and lasted for 14 continuous days. After the last administration of gavage orally treatment, all mice were anaesthetized and killed by cervical dislocation method to obtain tumor tissue completely for further HE staining measure and detection of TLR2, TLR4, TLR6, TRAF6 and MyD88 in tumor tissue with the method of RT-qPCR and immunohistochemistry. Meanwhile, the tumor growth was observed and the general conditions of mice were recorded. Results The model group was rich in tumor cells; the sizes of cells were different; the volume was large; the nucleus was deeply stained and the heterotypic shape was obvious, and the small focal necrosis was seen. The number of tumor cells in each administration group was reduced; the arrangement was loose; the cell volume was significantly reduced, and the nuclear pyknosis was reduced. Cell necrosis significantly increased; the number of interstitial blood vessels decreased; collagen fibers increased, especially in modified Danggui Beimu Kushen Pills high-dose and low-dose combined with DDP groups. Compared with the model group, the expressions of TLR2, TLR4, TLR6, TRAF6 and MyD88 mRNA and protein decreased in each administration group. TLR2, TLR4, TLR6, TRAF6 and MyD88 were lighter and weakly positive expressed in modified Danggui Beimu Kushen Pillshigh-dose and low-dose combined with DDP groups, the protein changes were more obvious Compared with DDP positive control group, modified Danggui Beimu Kushen Pills high-dose and low-dose groups. Conclusion Modified Danggui Beimu Kushen Pills can down-regulate TLR2, TLR4, TLR6, TRAF6 and MyD88 expression of tumor tissue in MFC gastric cancer bearing mice at both mRNA and protein levels to play anti-tumor pharmacology action.

Objective To observe the effects of Jiuxieling Granules on the expressions of MyD88 and IRAK1 in ulcerative colitis model rats with spleen-kidney yang deficiency; To discuss its mechanism of action. Methods Animal models were established by compound methods. 90 Wistar rats were randomly divided into blank group, model group, positive medicine group, and Jiuxieling Granules high-, medium-, and low-dose groups. Each administration group was given relevant medicine for gavage. RT-qPCR, SP immunohistochemistry and Western blot were used to detect mRNA and proteins of MyD88 and IRAK1 in colon tissues.
