Objective To investigate the expression of survivin (an apoptosis inhibitor) in thyroid carcinoma and its relationship with vascular endothelial growth factor (VEGF) expression. Methods Sixty-eight cases of thyroid carcinoma, 12 cases of thyroid adenoma and 10 cases of normal thyroid tissue were involved. Immunohistochemistry (SABC method) was used to detect the expression of survivin, caspase-3 and VEGF, and then their relationship with the major clinicalpathologicalparametersofthyroidcarcinoma was analysed. Results No survivin was expressedinnormalthyroidtissue,butsurvivinwasweakly expressed in thyroid adenoma (16.7%) and strongly expressed in thyroid carcinoma (57.4%); caspase-3 was obviously expressed in three kinds of tissue (70.0%, 75.0%, 69.1%), and VEGF was expressed in 75.0% of thyroid carcinoma and 41.7% of thyroid adenoma. In thyroid carcinoma, survivin expression had no correlation with caspase-3 expression, but significant positive correlation existed between surviving and VEGF (r=0.302,P

AIM To establish an HPLC method for the simultaneous content determination of saikosaponin a,saikosaponin c,saikosaponin d,rutin,quercetin,isorhmnetin and kaempferol in the aerial and underground parts of “Zhongchai No.2” (Bupleurum chinense DC.from Sichuan Province).METHODS The analysis of “Zhongchai No.2” methanol extract was performed on a 30 ℃ thermostatic Hypersil GOLD column (250 mm × 4.6mm,5.0 μm),with the mobile phase comprising of acetonitrile-0.1％ phosphoric acid flowing at 0.8 mL/min in a gradient elution manner,and the detection wavelength was set at 210 nm.RESULTS Seven constituents showed good linear relationships within their own ranges (r≥0.999 1),whose average recoveries were 96.30％-102.7％ with the RSDs of 0.95％-3.8％.There were a lot of flavonoids in the aerial parts of samples,while a large number of saponins existed in the underground parts,but almost no flavonoids were found.CONCLUSION The aerial parts (stems and leaves) of “Zhongchai No.2” also have medicinal value,to which we should pay attention.

Objective To analyze the changes in the expression of Toll-like receptors 4 (TLR4) and 7 on the surface of murine bone marrow-derived dendritic cells following dengue virus type 2 (DEN2) infection.Methods DEN2 NGC strain was infected into BALB/c suckling mice through intracranial injection and injected into C6/36 cells to induce the in vivo and in vitro proliferation of DEN2, respectively.RT-PCR was performed to identify DEN2 RNA.Reed-Muench method was used to determine the 50% tissue culture infective dose (TCID50) of DEN2.Dendritic cells (DCs) were prepared by stimulating bone marrow cells isolated form C57BL/6 mice with IL-4 and GM-CSF and then identified by flow cytometry.The prepared murine bone marrow-derived DCs were infected with DEN2 and observed with direct immunofluorescence assay.Dynamic changes in the expression of CD11c, CD86 and I-A/I-E molecules on DCs after DEN2 infection were detected by flow cytometry.Levels of DEN2 RNA and the expression of TLR4 and TLR7 at mRNA level were dynamically detected by real-time quantitative PCR.Results The TCID50 of DEN2 to C6/36 cells was 10-5.8.Murine bone marrow-derived DCs were acquired with a purity of 70% and could be infected with DEN2 in vitro.The percentages of CD86 and I-A/I-E molecules on the surface of DCs infected with 1×105 TCID50 of DEN2 were statistically different from those of the negative control group.Neither of the two groups showed a significant difference in the percentages of membrane molecules over time.However, the percentages of membrane molecules on DCs increased with increasing viral load.Compared with the negative control group, the levels of DEN2 RNA in infection groups were increased with increasing virus load, while the expression of TLR4 and TLR7 on DEN2 infected-DCs at mRNA level was decreased with increasing viral load.Conclusion DEN2 infection promotes the maturation of DCs.Expression of TLR4 and TLR7 on DEN2 infected-DCs at mRNA level decreases with increasing viral load, which suggests that TLR4 and TLR7 are closely related to viral infection and play a certain role in the pathogenesis of DEN infection.

Objective To detect the expression levels of multiple serum chemokines including IFN-inducible T cell chemoattractant (ITAC),Fractalkine,macrophage inflammatory protein (MIP)-3α,IL-8,MIP-lα,MIP-1β in patients with lung cancer and explore their association with the clinical characteristics of lung cancer as well as the correlations among these chemokines.Methods Forty newly diagnosed patients with lung cancer and thirty healthy controls were enrolled for detection of the serum levels of 6 kinds of chemokines by Luminex technology.The correlations of clinical characteristics of lung cancer with these chemokines and the correlations among these chemokines were analyzed by SPSS 17.0 software.Results The serum levels [M (QR)] of IL-8,Fractalkine and MIP-3α in patients with lung cancer were 5.16 (4.74),128.45 (141.89),10.31 (8.88) respectively,and 2.01 (0.95),61.46 (74.81),8.08 (5.87) respectively in control group,with significant differences (Z =-4.783,P ＜0.001;Z =-4.046,P ＜0.001;Z =-3.105,P =0.002).The expression of MIP-1β in lung adenocarcinoma was significantly higher than that in squamous carcinoma [18.32 (12.27) vs.13.72 (7.31),Z =-2.212,P =0.027],and of ITAC in squamous carcinoma was significantly higher than that in small cell lung cancer [24.51 (22.48) vs.9.28 (4.85),Z =-2.460,P =0.014].The expressions of MIP-3α and Fractalkine were positively correlated in the two groups (r =0.619,P＜0.001;r=0.766,P＜0.001).Conclusion The expressions of IL-8,Fractalkine and MIP-3α increase significantly in lung cancer patients,and they are may play important roles in metastatic lung cancer.
