Aim To observe the effect of agiophyllum oligo saccharides ( AOS) on reducing blood sugar, im-proving insulin resistance on diadetic Goto-Kakizaki ( GK) rats, and to explore the possible mechanism. Methods The type 2 diabetes GK rats were divided into six groups: model control group ( MC ) , Glenn benzene urea group ( GLB ) , high agriophyllum squar-rosum coarse oligosaccharides ( AOS-H ) , medium ( AOS-M ) , low dose group ( AOS-L ) , homologous Wistar rats as normal control ( NC ) . All animals were administered with AOS by oral gavage, for 8 weeks. The fasting blood glucose ( FBG) , random blood sugar ( RBG) , glucose tolerance ( OGTT) were tested before and after administration. No fasting sugar load status before and after dosing changes in blood glucose and serum insulin level in rats were measured in the previ-ous 8 weeks. At the end of administration, the fasting serum glucose ( FPG) , insulin ( FINS) , OGTT and in-sulin resistance index ( HOMA IR) in fasting rats were analyzed. Lastly, the pathological changing of pancreas was observed by HE staining. Results The blood glucose of fasting GK rats was not influenced after using AOS. However, the random blood glucose significantly reduced, the glucose tolerance was improved and AUC was obviously reduced (P < 0. 01) after using AOS. The best effect was on AOS-M group, which was similar with Glenn benzene urea. Through our research, we found AOS could promote release of insulin. This best effect was on AOS-M and AOS-L groups, and the time and quantity of release were better than Glenn benzene urea. Finally, AOS inhibited the pathological changes of islet tissue on GK rats, increased the quantity of pancreas and islet cells. Compared with model group, the changing of islet structure was significantly reduced in AOS group. Conclusion AOS could obviously improve insulin resistance and lower blood sugar, and the mechanism of this effect may be related with rapidly promoting insulin release, increasing the islet cell proliferation,and improving the function of islet.

Objective To investigate the in vitro effect of low dosage of paclitaxel on normal murine bone marrow-derived dendritic cells(mDCs)and its role in reactivating tumor-pulsed DCs. Methods The concentration of paclitaxel which could induce 30% apoptosis of 3LL cell lines was figured out.mDCs were generated from murine bone marrow precursors.Cell culture insert system was used and four groups were divided as following: mDC,mDC+3LL,mDC+ low dose of paclitaxel,and mDC+3LL with 30% apoptosis induced by low dose of paclitaxel.The phenotypes,chemoattractive function to MIP1? and MIP-3?,and viability in activating allogeneic T cell proliferation of DCs in the four groups were analysed. Results Paclitaxel of 50 nmol/L could induce 30% apoptosis of 3LL,and had protective effects on DCs.It could stimulate the maturation of mDCs by up-regulating the phenotypes of CD11cCD80,CD11cCD86,CD11cCD40 and CD11cCDIab,and could enhance the chemoattractive function to chemokine MIP-3?.Compared with those cocultured with 3LL,DCs pulsed with apoptosis antigen of 3LL cell which was induced by 50 nmol/L paclitaxl up-regulated the phenotype of CD11cCD40,enhanced the the chemoattractive function to MIP1? and MIP-3?,and activated the proliferation of T cells. Conclusion Paclitaxel of 50 nmol/L can stimulate the maturation of DC,and can partially recover the phenotype and function of tumor-pulsed DC.

Objective To analyze the treatment and prognosis of lung cancer patients with brain metastases.Methods The clinical data of 352 lung cancer patients with brain metastases were retrospectively reviewed.According to the treatment modalities,patients were divided into palliative therapy group(n=28),simple whole brain radiotherapy(WBRT)or chemotherapy group(n=49)and comprehensive treatment group(n=275).Comprehensive treatment group was subdivided into WBRT plus chemotherapy group(n=192),stereotactic radiosurgery(?knife)plus chemotherapy/WBRT group(n=72,n=16 for?knife plus chemotherapy and n=56 for?knife plus WBRT and chemotherapy)and neurosurgical resection plus chemotherapy/WBRT group(n=11).In comprehensive treatment group,111 patients received chemotherapy≤3 cycles,and the other 164≥4 cycles.Survival curves of each group were drawn respectively,and both survival time and survival rates were compared among groups.Results The median survival time of palliative therapy group,simple WBRT or chemotherapy group,WBRT plus chemotherapy group,?knife plus chemotherapy/WBRT group and neurosurgical resection plus chemotherapy/WBRT group was 1.7,3.2,9.0,11.6 and 17.1 months,respectively.It was revealed by survival analysis that WBRT plus chemotherapy group was better than simple WBRT or chemotherapy group (P=0.0000),?knife plus chemotherapy/WBRT group was better than simple WBRT or chemotherapy group(P=0.0000),and neurosurgical resection plus chemotherapy/WBRT group was better than simple WBRT or chemotherapy group and WBRT plus chemotherapy group(P=0.0001,P=0.0229).There was no significant difference in survival rates between neurosurgical resection plus chemotherapy/WBRT group and?knife plus chemotherapy/WBRT group(P=0.2543),and there was no significant difference in survival rates between those with?knife plus chemotherapy and those with?knife plus WBRT and chemotherapy(P=0.3804).In comprehensive treatment group,the survival rates of those with chemotherapy≥4 cycles was significantly higher than that of those with chemotherapy≤3 cycles(P=0.0000). Conclusion Both WBRT plus chemotherapy and?knife plus chemotherapy and WBRT are effective modalities for the treatment of lung cancer patients with brain metastases,and the latter has the tendency to gain more survival benefit.There is no significant difference in the survival time between patients receiving?knife with WBRT and those without.It is proper for the patients to have no less than 4 cycles of chemotherapy.
