Objective To establish the baseline data about gross α and gross β radioactivity in local foods through a preliminary investigation in Urumqi City.Methods The edible parts of six types of foods, including cereals, vegetables, fruit, nuts, meat and dairy food, were pretreated and sampled.MPC 9604 low background o and gross β measuring instrument was used for determination of gross α and gross β radioactivity.Results The natural gross ot and gross β radioactivity in the cereal, vegetables, fruits, nut, meat, dairy food were 0.88-10.80 and 22.20-148.67 in cereals, 1.17-24.24 and 21.41-318.84 in vegetables, 1.44-4.89 and 43.90-112.67 in fruits, 17.49-43.72 and 287.81-747.40 in nut, 3.04 -19.77 and 41.55-164.51 in meat, and 2.07-2.94 and 44.07-59.02 Bq/kg in milk, respectively.Conclusions There are some differences in the gross natural radioactivity between Urumqi and the other provinces and cities due to possible regional differences.In order to further ascertain baseline of natural radioactivity in food in Urumqi, larger sample sizes and more diverse food types are needed for purposes of dynamic monitoring.

AIM:Nitroxyl ( HNO) increases myofilament Ca 2+responsiveness relative to increases in intracel-lular Ca2+in cardiac muscle.In this study, we further investigated this effect of HNO on trabecular muscles from phospho-lamban knockout ( PLB-KO) and wide-type ( WT ) mice using a novel HNO donor , 1-nitrosocyclohexyl acetate ( NCA ) . METHODS:Trabecular muscles were dissected from the right ventricles of the rat hearts and mounted between a force transducer and a motor arm.The muscles were superfused with K-H solution (pH 7.4) at room temperature.Fura-2 was loaded into the trabecular muscles via electrophoresis .The length of the sarcomere was set to 2.2~2.3μm.During stead-y-state activations, the maximal Ca2+-activated force and Ca2+required for 50% activation were measured.RESULTS:The intracellular Ca 2+transients and force of the PLB-KO muscles at baseline were higher than those of the WT muscles and exhibited a negative force-frequency relationship (FFR).NCA (2.5μmol/L) increased systolic force in both PLB-KO group and WT group at any given [Ca2+]o.However, there was more dramatic increase in the force development due to moderate increases in the intracellular Ca 2+transients in the WT muscles when external Ca 2+increased from 1.5 to 4.5 mmol/L under NCA.NCA did not affect the negative FFR in PLB-KO muscle.Steady-state force-Ca2+relations obtained from skinned muscles were not different between the 2 groups, while NCA increased Ca2+responsiveness in skinned mus-cles from both PLB-KO and WT mice.CONCLUSION:HNO increases force development in both PLB-KO and WT mus-cles as a result of increases in myofilament Ca 2+responsiveness .The increased intracellular Ca 2+transients are accompa-nied by greater force development in WT mice , suggesting that HNO improves Ca 2+activation and establishes HNO as a positive inotropic agent with novel mechanisms .

A benzyl functionalized ionic liquid, 1-benzyl-3-methylimidazolium bis [( trifluoromethyl ) sulfonyl]imide ([BeMIM][Tf2 N]), was synthesized and characterized as an extraction solvent of dispersive liquid-liquid microextraction ( DLLME) for enrichment and determination of 5 organophosphorus pesticides (phoxim, fenitrothion, chlorpyrifos, phorate and parathion) and 2 aromatic compounds (chloronaphthalene and anthracene) from environmental water samples by high-performance liquid chromatography ( HPLC). [BeMIM] [ Tf2 N] had higher extraction efficiency than 1-octyl-3-methylimidazolium bis [( trifluoromethyl) sulfonyl]imide and common organic solvents such as CCl4 and C2 Cl4 . The extraction was performed using 40 μL of [BeMIM][Tf2N] and 1 mL of methanol as extraction solvent and dispersive solvent respectively with centrifugal time of 5 min. Under the optimal conditions, the method proposed here provided a good linearity for all analytes with correlation coefficients between 0. 9994 and 0. 9998. The repeatability values, described as intra-day and inter-day relative standard deviations (RSDs) of five replicate experiments at three different concentrations of 10, 40 and 100 μg / L, were 1. 1% -4. 3% and 0. 8% -4. 8% , respectively. The limits of detection (LOD) were 0. 01 μg / L-1. 0 μg / L at a signal-to-noise ratio (S / N) of 3. This developed method was convenient and speedy, and could be employed to detect the analytes in three real environmental water samples with satisfactory relative recovery of 82. 7% -118. 3% and RSD of 0. 7% -5. 6% . Introduction of benzyl group into the imidazolium could obviously enhance the extraction efficiecny for analytes due to the π-πinteraction between [BeMIM] [ Tf2 N] and analytes. [ BeMIM] [ Tf2 N] was a satisfactory extraction solvent with a high enrichment factor of 339 and extraction efficiency of 81. 4% . Partition coefficients of all analytes in [BeMIM][Tf2 N]-DLLME system were determined and the extraction mechanism was discussed.

It is an urgent task to transform scientific research achievements on traditional Chinese medicine (TCM) into standard for the science and technology workers of TCM. The transformation not only improves the level of TCM standard, but also promotes the scientific research achievement on TCM into productivity. The Medium and Long-Term Strategic Development Plan for TCM Standardization issued by the State Administration of TCM of the People's Republic of China put forward reinforcement of study on method for transformation of TCM scientific research achievement into standard. Thus, this paper presented seven steps for the transformation on the basis of the TCM Standardization Regulation (trial) in order to provide some references.
