2-Methyl-1,3,6-trihydroxy-9,10-anthraquinone (MTA)  one of the major components isolated from the traditional  Chinese medicine Rubia yunnanensis  exhibited inhibitory activity on the proliferation of several  human cancer cell lines. The results from an annexin V-FITC (fluoresein-5-isothiocyanate) apoptosis assay  and DNA content analysis showed that MTA exerted cytotoxicity via apoptosis induction and G2/M cell cycle  arrest in human cervical carcinoma HeLa cells. Further  MTA was found to induce apoptosis of HeLa cells  through the mitochondria-mediated pathway. It caused the translocation of Bax to the mitochondria and  release of cytochrome c into the cytosol  which caused the cleavage of caspase and poly(ADP-ribose)  polymerase and finally triggered the apoptosis. Furthermore  the p53/p21/Cdc2-cyclin B1 signaling was  found related to the G2/M arrest caused by MTA. The over-expression of p21 and down-expression of  cyclin B1 caused by MTA inactivated the Cdc2-cyclin B1 complex of G2/M checkpoint and finally caused  the G2/M arrest in HeLa cells. This study demonstrated that MTA is a potential anti-cancer component of  R. yunnanensis  a folk anti-cancer herb used in Yunnan  China.

In order to rapidly develop the control system code of the Electromachanical Actuator(EMA)  the DSP development platform is established mostly based on the MATLAB  and the development metheod is researched.First  the DSP development platform archtecture in the environment of MATLAB is briefly introduced.And the principle of data exchange is showed.Then  the EMA hardware structure is necessarily explained  which one is for the developer to conveniently configure the system.Finally  the developer reasonably configures the DSP models used in the simulink and constitutes them to speed and position closed loop control system of the EMA  by using the RTDX and the MATLAB GUI. The EMA control system code will be debuged rapidly through this platform.The executed DSP code will be generated automatically.And the result of degugging would be showed on the MATLAB GUI.For generlly speaking  the difficulties of the EMA control system code development method is reduced and the development cycle is shortened through the MATLAB model.This system development method is fast and effective. 2011 IEEE.

Gas-assisted injection molding(GAIM)is a new kind of plastic processing technique. It is one of the most important developments in the injection molding industry. GAIM has many advantages such as lower injection pressure  lower warpage  better surface quality  lower material consumption  and shorten molding cycle time  etc. MPI/Gas module of Moldflow software can be used to simulate the GAIM process to optimize the whole molding process. In this study  the FM new truck interior ceiling handle was analyzed in GAIM process based on the MPI/Gas module. The simulation results showed the gas penetrating time  the contours of plastic layers thickness fraction of the parts and the gas volume fraction changing with time. The results can help technicians to determine the optimum process of the melt injection and the gas injection to ensure the final quality of the parts. 2011 Trans Tech Publications.

The trace of star trail is an important component of deep sky detection. The stars are low contrast targets  and their self-rotation will make their brightness change in cycle. Above all  the trail trace is vulnerable to the block and disturbance of other stars. Traditional one-dimensional maximum entropy thresholding algorithm is vulnerable to the noise  and the calculation of two-dimensional entropy methods is too large and takes too much time. This paper proposes an improved two-dimensional entropy threshold algorithm. We use recursion iteration method to eliminate the redundancy calculation  and reduce the size of two-dimensional histogram based on the deep sky stars characteristic  such as low contrast  fuzziness and the centralized histogram. We also combine our algorithm with the space trail trace model to forecast the star trace. Experiments results show  when the star are blocked or they turn dark  the method still can well extrapolate the star trace. Our method improves the capability of trailing the ebb and small star  and increases the precision of tracing. It is also robust to the noise  so there is a good application foreground for the method.
