Objective To investigate the inducing effects of selenium dioxide(SeO2 ) on the apoptosis in human cervical carcino-ma cell line Hela and its influence on the expression of apoptosis-related proteins caspase-3 and P53 .Methods Hela cells were trea-ted with different concentrations of SeO2 for 24 h in vitro ;the morphological changes of Hela cells were observed by the optical mi-croscope;the influence of SeO2 on the cell proliferation and vitality was examined by the MTT assay ;the flow cytometry was em-ployed to detect the cell apoptosis rate ;the expressions of caspase-3 and P53 proteins in Hela cells were determined by the Western blot analysis .Results Under the optical microscopy ,SeO2 generated the obvious influence on the cell growth morphology ,a large number of cells became rounded and shrunken ,and lost the normal form ,while the adherence cell number was evidently decreased and the proliferation was slowed down ;the MTT results showed that SeO2 markedly inhibited the cell proliferation and viability in a dose-dependent manner ,in which ,the cell apoptosis rates induced by the 0 ,1 .875 ,3 .750 ,7 .500 ,15 .000 and 30 .000 μmol/L con-centrations of SeO2 were 3 .12% ,30 .56% ,33 .42% ,37 .50% ,45 .43% and 69 .38% respectively ,which revealing the obviously in-creasing trend;the Western blot assay revealed that SeO2 could up-regulate the caspase-3 and P53 levels ,and reached the peak value at the concentration of 7 .500μmol/L .Conclusion SeO2 could induce the cervical cancer cell apoptosis possibly by up-regulating the expressions of caspase-3 and p53 in Hela cells .

To analysis the differences between Tripterygium wilfordii and T. hypoglaucum, specimens of their leaves were collected from five production regions and analyzed by ultra performance liquid chromatography coupled with quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS). The data were analyzed by multivariate statistical method, such as hierarchical cluster analysis (HCA) principal component analysis (PCA) and orthogonal signal correction partial least square discrimination (OPLS-DA). Potential markers with VIP values above 5.0 and corresponding r values above 0.85, were selected and further tested by combining mann-Whitney nonparametric. Those with P < 0.001 and AUC = 1 were confirmed as metabolite markers to discriminate them from each other. Results revealed that the two species were obviously different in their leaf metabolites. Based on their mass spectra, 23 potential metabolite markers were identified to distinguish T. wilfordii from T. hypoglaucum.

Immuno-fluorescence technique can qualitatively determine certain nuclear translocation, of which NF-κB/ p65 implicates the activation of NF-κB signal pathways. Immuno-fluorescence analysis software with independent property rights is able to quantitatively analyze dynamic location of NF-κB/p65 by computing relative fluorescence units in nuclei and cytoplasm. We verified the quantitative analysis by Western Blot. When we applied the software to analysis of nuclear translocation in lipopolysaccharide (LPS) induced (0. 5 h, 1 h, 2 h, 4 h) primary human umbilical vein endothelial cells (HUVECs) , we found that nuclear translocation peak showed up at 2h as with calculated Western blot verification results, indicating that the inventive immuno-fluorescence analysis software can be applied to the quantitative analysis of immuno-fluorescence.

OBJECTIVETo make full use of the plant resources of Panax notoginseng, nutritional compositions and mineral elements were analyzed in aerial part of P. notoginseng from different areas in Yunnan.
METHODUsing the national standard method, water, ash, crude fat, crude fiber, crude protein and mineral elements were determined in aerial part of P. notoginseng from different growing areas.
RESULTResults showed that there were higher contents of crude fiber and crude protein, and lower content of crude fat in the stems and flowers of P. notoginseng. Meanwhile, a large number of mineral elements were determined in two locations of P. notoginseng, and the contents of Zn, Fe, Mn, Ca and Mg were obvious higher among these mineral elements.
CONCLUSIONThis study showed that the stems and flowers of P. notoginseng were nutritious and suggested that the aerial part may be utilized as new resources foods.

Sanqi (Panax notoginseng) is a valuable unique herb, and is also one of the very fast developed varieties of traditional Chinese medicines in recent years with increasing role in traditional Chinese medicine industry. This paper summarized the main experience, industry development and present situation, pointed out the main problems existing in the industry development. On this basis, we put forward the targets and measures for the development of the Sanqi industry in to provide decision-making reference for the sustainable development of the Sanqi industry in China.

To study effect of vitrification state of protective solutions on recovery of red blood cells after lyophilization, four protective solutions composed of isotonic buffers containing 7% DMSO (v/v) and 20%, 30%, 40% or 50% polyvinylpyrrolidone (PVP) (w/v) were adopted. Vitrification state of protective solutions was examined first when white ice crystal appeared in any protective solution during freezing or thawing, if the used solution was not a vitrification solution. Red blood cells were lyophilized in MINILYO45 freeze-dryer after washing, mixing with protective solutions and prefreezing. After lyophilization, the samples were quickly rehydrated by 37 degrees C rehydration solution. The results showed that in vitrification and devitrification experiments, white ice crystal appeared in solution of 20% PVP + 7% DMSO and 30% PVP + 7% DMSO during freezing and thawing; vitrification appeared in solution of 40% PVP + 7% DMSO during freezing, but devitrification appeared during thawing; vitrification appeared in solution of 50% PVP + 7% DMSO during freezing and thawing. After rehydration, the recoveries of red blood cells and hemoglobin in 40% PVP + 7% DMSO group were (81.36 +/- 14.94)% and (77.54 +/- 12.86)%, which were significantly higher than that in 20% PVP + 7% DMSO, 30% PVP + 7% DMSO and 50% PVP + 7% DMSO groups (P < 0.01). The concentration of free hemoglobin in 40% PVP + 7% DMSO group was also significantly lower than that in other three groups (P < 0.01). With increase of PVP concentration in protective solutions, vitrification state and protective effect of these solutions also increased; when concentration of PVP in protective solution was 40% though it was not a vitrification solution, the effect of lyophilization was the best; but when concentration of PVP further increased to 50%, though it was a vitrification solution, the effect decreased. It is concluded that excessive vitrification state could not benefit lyophilization of red blood cells.
