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.

The yeast fusant ZFF-28, which is high in biomass production and rich in selenium, was constructed after mutagenesis and protoplasts fusion between yeast strains. The total selenium content of ZFF-28 is 1.8 and 1.0 times higher than that of the parental strains Saccharomyces cerevisiae ZY-67 and Saccharomyces kluyveri SZY-198 respectively. Using single factor tests and a L16(4(3) x 2(1)) orthogonal design, the cultivation conditions was optimized as: 50mL culture in 250mL shake flasks in molasses containing 6% sugar and 60microg/mL Se at 28 degree C for 25h at 220 r/min, with the initial pH adjusted to 6.0 - 6.5. Under the optimized conditions, the biomass (dry weight) reached 8.2g/L and the Se content of the cells reached 2050microg/g, with organic and inorganic Se contents being 91% and 9% respectively.

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.

The role of autophagy is known to be highly complex and context-dependent, and may be characterized as both tumor suppression and tumor promotion in some tumors, such as breast cancer and prostate cancer. This review outlines recent advances in the studies of the involvement of autophagy in the development, progression and treatment of prostate cancer, focusing on autophagy modulation during androgen deprivation, with a special discussion on the regulatory effect of androgens on the autophagy of prostate cancer cells. A critical evaluation and analysis of the studies suggests that autophagy inhibition combined with androgen deprivation therapy is a promising approach to the treatment of prostate cancer.

The DNA structures could be altered or even damaged by exogeous or endogenous factors during cell proliferation. Failure of effective and timely repair will lead to cell cycle arrest or apoptosis. By taking the advantage of the quick proliferation of cancer cells, DNA damage induction, cell cycle arrest and apoptosis promotion have become important strategies for ant-cancer chemotherapy. Previous reports showed that an array of natural compounds inhibit cancer cell proliferation by inducing DNA damage, which have therapeutic potentials for anti-cancer drug research and development.

OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.
METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.
RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.
CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

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.

Microbiology 1992;0(02):-
The enzyme activity of ?- Acetolactate Decaroboxylases (ALDC) from different microbes was studied, the results demonstrated that it was quite different among them. There were diversities of their enzyme reaction velocities. It was clear that the enzyme activity was affected by the pH of the enzyme reaction system, for example, the optimum pH of ALDC from Lactococcus lactis was 6. 6, while for Aerobacter Aerogenes it was 5. 8. Addition leucine,valine and isoleucine into enzyme reaction system obviously affected the enzyme activity of ALDC from different microbes.
