1.Exercise-induced Weight Reduce and Leptin (review)
Chinese Journal of Rehabilitation Theory and Practice 2006;12(10):883-885
With the standard of living improved, people had less and less interests in exercise, adiposity has being a problem that people have to be up against all over the world. Exercise can step up energy expenditure, decrease fat accumulation, minish the volume of fat cell, and is one of widely used, effective, safe, economical measures of anti-adiposity. The adaptable change of neuroendocrine system in exercise quicken up fat to burn more. Leptine is an important signal of measuring fat content of body. The relationship between adiposity and leptin, and the effect of exercise on leptin was reviewed in this paper.

To establish a convenient and rapid method for identification of Pseudostellariae Radix by molecular identification, the rDNA-ITS sequences of Pseudostella riaheterophylla and its adulterants had been aligned to find out specific fragment. The specific primers against the fragment were designed and the PCR amplification conditions were optimized. The fluorescence reaction of the PCR products colored by 100 x SYBR Green I was observed under UV. The concentration of reaction buffer included 5.5 μL DNA Taq polymerase premix, 10 pmol Tzs-2F and 10 pmol Tzs-2R, 20-80 ng template DNA, and plus double sterile distilled water to 25 μL. The PCR thermal profile was as follows: predenaturation at 95 degrees C for 1 min, followed by 30 cycles of denaturation at 95 degrees C for 5 seconds, primer annealing and extension at 56 degrees C for 15 seconds, then it was extension at 72 degrees C for 30 seconds. The fluorescence reaction of Pseudostellariae Radix showed green fluorescence, while adulterants had not. Extraction, amplification DNA and all steps of molecular identification could be completed successfully in 40 minutes. The approach could amplify DNA template of Pseudostellariae Radix specificity, and its product with 1 μL 100 x SYBR Green I could engender green fluorescence under UV. The method was simple and accurate, so it could be used for identification of Chinese traditional medicine.

Objective · To observe effect of 17β estrodial (17β E2) with different concentrations on C type natriuretic peptide (CNP), insulin like growth factor 1 (IGF1), and natriuretic peptide receptor B (NPR-B) expression and proliferation of growth plate chondrocytes of rats in vitro. Methods · Eight Wistar rats were sacrificed and their epiphyseal cartilages of the upper tibias were separated to obtain chondrocytes on the 14th day after birth. Then chondrocytes were cultured with 17β E2 in different concentrations (10-4、10-6、10-8、10-10 and 10-12 mol/L) for 48 h, while control group was cultured without 17β E2. CCK8 method, ELISA and qRT-PCR were used to analyze the proliferation of chondrocytes, the levels of CNP and IGF1 in culture medium and mRNA levels of CNP, NPR-B and IGF1, respectively. Results · 17β E2 in different concentrations affected the proliferation of growth plate chondrocytes significantly. When the concentration of 17β E2 was 10-8 mol/L, it had the strongest effect on the cell proliferation. When the concentration increased to 10-4 mol/L, the proliferation of chondrocytes was inhibited. With the increasement of 17β E2 concentration, the levels of CNP in the culture medium and the mRNA levels of CNP in the chondrocytes were significantly different. The highest levels of CNP protein and mRNA both appeared in 10-8 mol/L group, while the lowest levels both appeared in 10-4 mol/L group. IGF1 and its mRNA also reached the highest levels in 10-8 mol/L group,but the lowest concentration and mRNA level were in 10-10 mol/L group and 10-12 mol/L, respectively. Both CNP mRNA and protein levels were positive correlated with the proliferation of chondrocytes (P=0.000). Nevertheless, there was no significant correlation between the proliferation of chondrocytes and IGF1 mRNA or protein levels (P>0.05). Conclusion · 17β E2 modulates proliferation of rat growth plate chondrocytes in a dose-effect manner. It enhances proliferation at relatively low concentrations (10-10-10-8 mol/L) and inhibits proliferation at high concentration. This effect is positively related to CNP expression in chondrocytes.

As a clean, efficient, and renewable energy, hydrogen is regarded as a promising alternative. Because of using biomass as substrate, microbial fermentative hydrogen production can meet the need of sustainable development. The factors affecting the process of microbial fermentative hydrogen production, are analyzed in this paper on the basis of microorganisms, substrates, products and operative parameters. The parameters related to hydrogen production from organic wastes, are also mentioned.
