The study is aimed to make the most of available space of Dendrobium officinale cultivation facility, reveal the yield and functional components variation of stereoscopic cultivated D. officinale, and improve quality, yield and efficiency. The agronomic traits and yield variation of stereoscopic cultivated D. officinale were studied by operating field experiment. The content of polysaccharide and extractum were determined by using phenol-sulfuric acid method and 2010 edition of "Chinese Pharmacopoeia" Appendix X A. The results showed that the land utilization of stereoscopic cultivated D. officinale increased 2.74 times, the stems, leaves and their total fresh or dry weight in unit area of stereoscopic cultivated D. officinale were all heavier than those of the ground cultivated ones. There was no significant difference in polysaccharide content between stereoscopic cultivation and ground cultivation. But the extractum content and total content of polysaccharide and extractum were significantly higher than those of the ground cultivated ones. In additional, the polysaccharide content and total content of polysaccharide and extractum from the top two levels of stereoscopic culture matrix were significantly higher than that of the ones from the other levels and ground cultivation. Steroscopic cultivation can effectively improves the utilization of space and yield, while the total content of polysaccharides and extractum were significantly higher than that of the ground cultivated ones. The significant difference in Dendrobium polysaccharides among the plants from different height of stereo- scopic culture matrix may be associated with light factor.

A multiplex real-time PCR was developed to detect ctxA of Vibrio cholerae, gyrB and tdh of Vibrio parahaemolyticus simultaneously. The multiplex real-time PCR were evalidated by detection for the three genes in 47 toxigenic V. cholerae O1 and O139 strains (ctxA+; O1=3, O139=44), 25 non-toxigenic V. cholerae strains (ctxA-; O1=12, O139=6, non-O1 and non-O139=7), 116 V. parahaemolyticus strains with or without tdh (73 or 43) and 9 other bacteria strains. The specificity and sensitivity of the multiplex real-time PCR in detection for the ctxA and the tdh genes in the strains tested were both 100.0%, compared to the results by routine PCRs. In the detection for V. parahaemolyticus specific gyrB using the multiplex real-time PCR, all of 116 V. parahaemolyticus strains were positive, and 9 other strains and 72 V. cholerae strains were all negative. The multiplex real-time PCR is a sensitive, specific and quick assay not only for detecting virulence genes of V. cholerae and V. parahaemolyticus but also for identifying V. parahaemolyticus at species level. In addition, two real-time PCRs for detection of V. parahaemolyticus virulence genes trh1 and trh2 were also developed.

OBJECTIVETo investigate the relationship between vascular endothelial growth factor C (VEGF-C) expression, VEGFR-3 expression, lymphangiogenesis and angiogenesis in human non-small cell lung cancer (NSCLC).

METHODSSeventy-six NSCLC samples were stained for VEGF-C, VEGFR-3 and CD34 with immunohistochemical methods. Assessment of lymphatic vessel density (LVD) and microvessel density (MVD) was performed. The expressions of VEGF-C in 24 fresh NSCLC samples were determined with Western blot assay.

RESULTSOf the 76 NSCLC cases, 55 were VEGF-C positive and 40 were VEGFR-3 positive in cancer cells. A significant positive correlation was found between VEGF-C expression and VEGFR-3 expression in cancer cells (P < 0.05). VEGF-C expression was negatively associated with differentiation of tumor cells (P < 0.05). VEGF-C expression and VEGFR-3 expression were positively associated with lymph node metastasis and lymphatic invasion (P < 0.05). LVD was positively related to VEGF-C expression, lymph node metastasis, lymphatic invasion and clinical stage (P < 0.05). There was a significant correlation between LVD and MVD (R = 0.732, P < 0.05). Patients with positive VEGF-C expression had worse outcomes than those with negative VEGF-C expression (P < 0.01).

CONCLUSIONSIn NSCLC, VEGF-C and VEGFR-3 are related to the lymphangiogenesis, angiogenesis, and occurrence and development of lung cancers. VEGF-C expression could be a useful predictor of poor prognosis in NSCLC.

OBJECTIVETo study the effect of Fuzheng Sanjie recipe in regulating tumor-associated macrophages (TAMs) in Lewis lung cancer mice.

METHODEfforts were made to establish the Lewis lung cancer mouse model, weigh tumors and calculate the anti-tumor rate. The immunohistochemical method was used to examine the infiltration degree of CD68 + in tumor tissues in each group. ELISA was used to examine the content of IFN-γ, TGF-β, IL-4, IL-13, IL-6, IL-10, IL-12, TNF-α in mice serum.

RESULTCompared with the tumor-bearing model group, all of the other groups showed higher tumor inhibition rates, i. e. 50.28% for the DDP group, 34.37% for the TCM-preventing group and 66.76% for the Chinese and western medicine group, with statistical difference (P < 0.05), but without statistical difference in the infiltration degree of CD68+. The expressions of the IFN-γ, IL-6, IL-12 in tumor-bearing groups were lower than that in the blank control group, but with higher contents of IL-4, IL-13, TGF-β. Intervened with different drugs, there were significant differences in content among some relevant cytokines (P < 0.05), as well as statistical differences among the TCM prevention group, the Chinese and western medicine group and the tumor-bearing control group (P <0. 05) , but without statistical difference in TNF-α and IL-10 content from the tumor-bearing control group (P < 0.05).

CONCLUSIONFuzheng Sanjie recipe could reverse the immune remodeling effect and control the tumor growth by down-regulating the expressions of IL-4, IL-13, TGF-α in lung cancer immune microenvironment and up-regulating the expression of IFN-γ.

Objective To study the effect of different concentrations of fluoride on cultured human umbilical vein vascular endothelial cells(HUVEC). Methods Different doses of sodium fluoride (NaF) were added to HUVEC culture medium, fluoride concentrations were 0(control), 100,400,700,1000,2000 μmol/L, respectively,6 re-set hole in each group. After continuous culture for 48 h, cells and culture medium were collected. Cell morphology was studied by Wright-Giemsa staining; cells apoptosis was determined by acridine orange fluorescence staining; cell activity was measured by methyl thiazolyl tetrazolium (MTT) assay; superoxide dismutase (SOD),glutathione peroxidase(GSH-Px) activity, malonaldehyde(MDA) content, induced nitricoxide synthase(iNOS), and endothelia nitricoxide synthase(eNOS) activity in cell culture medium were determined by spectrophotometry; cell iNOS mRNA and eNOS mRNA expression were detected by RT-PCR; intercellular adhesion molecule-1 (ICAM-1)and vascular cell adhesion molecule-1 (VCAM-1) levels were detected by double antibody sandwich ELISA method.Results With increased dose of fluoride, HUVEC cells decreased, the structure changed. In 400 - 2000 μmol/L group, the SOD activity[(6.627 ± 0.213), (6.668 ± 0.152), (5.935 ± 0.122), (4.755 ± 0.182)kU/L] was lower than those of the control group[(7.457 ± 0.398)kU/L, P ＜ 0.05 or ＜ 0.01], GSH-Px activity[(481.284 ± 43.785),(492.223 ± 16.474), (382.762 ± 25.167), (293.687 ± 24.881 )kU/L] was also lower than those of the control group [(585.078 ± 47.323)kU/L, P ＜ 0.05 or ＜ 0.01], MDA level[(0.609 ± 0.011 ), (0.646 ± 0.016), (0.852 ± 0.013),(1.188 ± 0.045)nmol/L] was higher than those of the control group[(0.512 ± 0.027)nmol/L, P ＜ 0.05 or ＜ 0.01];iNOS activity[(3.604 ± 0.115), (3.615 ± 0.075), (3.848 ± 0.103), (4.275 ± 0.079)kU/L] also was higher than those of the control group[(2.798 ± 0. 136)kU/L, all P ＜ 0.01], iNOS mRNA expression increased, eNOS activity [(5.539 ± 0.079), (5.503 ± 0.064), (5.226 ± 0.142), (4.809 ± 0. 107)kU/L] decreased compared to those of control group[(5.996 ± 0.155)kU/L, P ＜ 0.05 or ＜ 0.01], eNOS mRNA expression decreased; ICAM-1 levels [(0.852 ± 0. 102), (0.886 ± 0.061 ), (0.961 ± 0.158), (1.418 ± 0. 167)μg/L] increased compared to those of the control group[(0.687 ± 0.046)μg/L, P ＜ 0.05 or ＜ 0.01], VCAM-1 levels[(2.719 ± 0.197), (2.946 ± 0.167),(3.173 ± 0.225 ), (3.613 ± 0. 153 ) μg/L] was higher than those of the control group [(2.375 ± 0.067 ) μg/L, all P ＜0.01]. Conclusions High concentrations of fluoride reduce the activity of antioxidant enzymes, which leads to metabolic disorders of nitric oxide and abnormal cytokines expression, thereby inhibiting vascular endothelial cell growth, structural change and induced apoptosis. This is an important factor in high fluoride-induced vascular endothelial injury.
