OBJECTIVE:
To investigate the effect of IL-17 and IL-23 in the pathogenesis of allergic rhinitis(AR) and non. allergic rhinitis(NAR).
METHOD:
Selected 156 cases of patients with allergic rhinitis (AR group) and 59 cases of patients with non-allergic rhinitis (NAR group), 60 cases of healthy people (control group). All cases in AR group and NAR groups were evaluated by a visual analog scale (VAS) score of nasal symptoms. Collected peripheral blood and nasal secretions in all cases and then detected IL-17 and IL-23 expression levels.
RESULT:
There was no significant difference in VAS score of AR group and NAR group (P>0. 05). IL-17 and IL-23 levels of serum and nasal secretions in AR group and NAR group were both higher than control group, with a highly significant difference (P <0. 05). The research showed a clear correlation between expression of IL-17 and IL-23 both in serum and nasal secretions of AR group and NAR(P<0. 05).
CONCLUSION
IL-17 and IL-23 may be important cytokines and IL-23/IL-17 pathway may play a significant role in the pathogenesis of allergic rhinitis and non-allergic rhinitis.

OBJECTIVE: To observe the protective effects of Yanggan Lidan Granules (YGLDG) on carbon tetrachloride (CCl(4))-induced liver damage in mice and to find out its mechanism. METHODS: A model of chronic liver damage was established in mice by intraperitoneal injection of CCl(4). After three weeks, those model mice were treated with low-, medium-, high-dose YGLDG, Danning Tablets and bifendate respectively for four weeks. Then the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), as well as the contents of superoxide dismutase (SOD) and malondialdehyde (MDA) in liver tissues were detected. RESULTS: YGLDG could significantly reduce the levels of serum ALT and AST in model mice, and the content of MDA was obviously decreased while the content of SOD was increased in liver tissue. CONCLUSION: The therapeutic effect of YGLDG on mice with CCl(4)-induced liver damage is to relieve the seriousness of liver damage, and its mechanism may relate to reducing peroxidation activity in liver tissue.

Relapse, which puzzled several generations of hematologists, is the bottle-neck of radical treatment for leukemias. The progress of Human Microbiome Project at the beginning of 21st century suggested that human body was a super-organism constituted by the core of human cells and symbiotic microorganisms. The elucidation and characterization of endogenous retrovirus and prion protein suggested the possible effects of co-evolutional microorganisms on human health. Recently, the elucidation of the roles of tunneling nanotubes in intercellular communication and transportation suggested a novel way for cellular communication and transport of oncogenic materials. The role and significance of in vivo cell fusion have been studied in more detail. On the other hand, donor cell leukemia was reported. All of these approaches provide novel insights for studying the mechanism of leukemia relapse. Based on previous work, the authors suggest the hypothesis: there are two possible mechanisms for the relapse of leukemias: the minimal residual disease (MRD) and intercellular transportation of oncogenic materials.

OBJECTIVETo determine if Ganoderma polysaccharides can antagonize prostaglandin E2 (PGE2)-induced suppression of murine splenocyte interferongamma (IFN-gamma) and tumor necrosis factor alpha (TNF-alpha) mRNA expression.
METHODSMixed lymphocyte culture reaction was used as the experimental model. The expressions levels of IFN-gamma and TNF-alpha mRNA were measured by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR).
RESULTSAfter the cultures were treated with PGE2 for 4 h, IFN-gamma mRNA expression was reduced as compared with the control, which was especially obvious when PGE2 concentrations exceeded 10 micromol/L (P<0.01). Ganoderma polysaccharides above 100 mg/L showed partial antagonistic effect against the inhibition of IFN-gamma by PGE2 at the fixed concentration of 20 micromol/L. Further studies indicated that PGE2 (20 micromol/L) impaired the expression of TNF-alpha mRNA after an 8-hour incubation and Ganoderma polysaccharides above 100 mg/L could partially antagonize this effect.
CONCLUSIONGanoderma polysaccharides can partially antagonize PGE2-induced suppression of murine splenocyte IFN-gamma and TNF-alpha mRNA expression.

Icaritin, a prenylflavonoid derivative from Epimedium Genus, has been shown to exhibit many pharmacological and biological activities. However, the function and the underlying mechanisms of icaritin in human non-small cell lung cancer have not been fully elucidated. The purpose of this study was to investigate the anticancer effects of icaritin on A549 cells and explore the underlying molecular mechanism. The cell viability after icaritin treatment was tested by MTT assay. The cell cycle distribution, apoptosis and reactive oxygen species (ROS) levels were analyzed by flow cytometry. The mRNA and protein expression levels of the genes involved in proliferation and apoptosis were respectively detected by RT-PCR and Western blotting. The results demonstrated that icaritin induced cell cycle arrest at S phase, and down-regulated the expression levels of S regulatory proteins such as Cyclin A and CDK2. Icaritin also induced cell apoptosis characterized by positive Hoechst 33258 staining, accumulation of the Annexin V-positive cells, increased ROS level and alteration in Bcl-2 family proteins expression. Moreover, icaritin induced sustained phosphorylation of ERK and p38 MAPK. These findings suggested that icaritin might be a new potent inhibitor by inducing S phase arrest and apoptosis in human lung carcinoma A549 cells.

OBJECTIVETo study the antitumor effect of saponin extracted from Tupistra chinensis Baker (STCB) against mouse sarcoma S-180 cell proliferation in vitro and in vivo and explore the primary mechanism of this effect.
METHODSCytotoxic effect of STCB on S-180 cells in vitro was evaluated by MTT colorimetry, and its effect against in vitro tumor growth was tested in Kunmin mice bearing S-180 implanted tumor. The morphological and ultrastructural changes of S-180 cells after saponin treatment in vitro were examined with light and transmission electron microscope. Flow cytometry was performed to examine the cell cycle and apoptosis of S180 cells treated with different concentrations of STCB with propidium iodide staining.
RESULTSSTCB could markedly inhibit S-180 cell proliferation in vitro with 50% inhibitory concentration of 34.64 microg/ml. STCB given by intragastric administration also significantly inhibited the growth of S-180 solid tumor, and the inhibition rate exceeded 30% at the dose of 0.5 g/kg, reaching 54.86% at 2 g/kg. Electron microscopy and flow cytometry revealed increased S180 tumor cell apoptotic rate with the increment of saponin concentration, along with increased percentage of cells in S phase and decreased cells in G(2)/M phase in response to 10 or 30 microg/ml STCB treatment. At the concentration of 60 microg/ml, however, STCB resulted in an opposite effect on the cell cycles, presumably due to its interference with mitosis at high concentrations.
CONCLUSIONSSTCB inhibits the growth of S-180 cells both in vivo and in vitro possibly by inducing cell apoptosis and interfering with the cell cycle progression of the tumor cells.
