A high-throughput method for screening drug multi residues was developed by quadrupole-time-of-flight( Q-TOF) mass spectrometry together with QuEChERS sample preparation technique. It has been used for the determination of 57 drugs, such as tetracyclines ( TCs ) , sulfonamides ( SAs ) , quinolones ( QNs ) , triphenylmethanes (TPMs), estrogens (ETs), androgens (AGs) and glucocorticoids (GCs) in fish. The optimized pretreatment conditions were examined. The target compounds were extracted with acetonitrile under the condition of Na2 EDTA-Mcllvaine buffer, and the usage of clean-up reagents was 25 mg anhydrous magnesium sulfate, 12. 5 mg octadecylsilane and 6. 25 mg N-Propylethylenediamine sorbent for extracted solvent of each milliliter. The positive results acquired by this high-throughput method were confirmed by liquid chromatography-tandem mass spectrometry ( LC-MS/MS) . The detection limit for these 59 drugs was in the range of 0. 5-5. 3 μg/kg. The method is time-saving, convenient, effective and wide coverage. Its sensitivity can meet the requirement of the detection of drug residues in aquatic products.

β- N-Acetyl- D-glucosaminidase ( NAGase, EC3.2.1.52) is a composition of the chitinases and cooperates with endo-chitinase and exo-chitinase to disintegrate chitin into N-acetylglucosamine. Pacific White Shrimp (P. vannamei) NAGase is involved in digestion and molting processes. Some pollutants in seawater affect the enzyme activity causing loss of the biological function of the enzyme, which affects the exuviating shell and threatens the survival of the animal. The effects of acetic anhydride on the enzyme activity for the hydrolysis of pNP-NAG have been studied. The results show that acetic anhydride can lead to reversible non-competitive inhibition at appropriate concentrations, and the IC50 is estimated to be 9.0 mmol/L. The equilibrium constants have been determined for acetic anhydride binding with the enzyme and/or the enzymesubstrate complexes. Inhibition kinetics of acetic anhydride on the enzyme has been studied using the kinetic method of the substrate reaction. The results suggest that at pH 6.2, the action of acetic anhydride on the enzyme is first quick equilibrium binding and then slow inhibition. The microscopic rate constants have been determined for inhibition and reactivation. The results show that k + 0 is much larger than k - 0, indicating the enzyme is completely inactivated at sufficiently large modificator concentration.

Objective To investigate the effects of 17?-estradiol (E2) on the gene expression of typeⅠA bone morphogenetic protein receptor (BMPR-ⅠA) and core-binding factor alpha 1 (Cbf?1) in rat bone marrow stromal cells exposed to the differentiation medium and to elucidate the effects of E2 on osteoblastogenesis. Methods Adherent bone marrow stromal cells were cultured in differentiation medium containing DEX (10 -7 mol/L), 1,25-(OH)2D3 (10 -9 mol/L) and different concentrations of E2. Effects of different concentrations of E2 on the gene expression of BMPR-ⅠA and Cbf?1 was quantified by RT-PCR based on the comparison with an internal reference, ?-actin expression, and identified by Northern blotting. Alkaline phosphatase (ALP) activity of cells was detected. Contents of type Ⅰ collagen were determined by Van Gieson staining. Results E2 could evidently inhibit the expression of BMPR-ⅠA and Cbf?1 mRNA during the differentiation process of bone marrow stromal cells into osteoblasts in a dose-dependent manner. These were confirmed by Northern blotting. The ALP activity increased in a concentration-dependent manner, but the amount of type Ⅰ collagen decreased in a concentration-dependent manner. Conclusion E2 can significantly inhibit the gene expression of BMPR-ⅠA and Cbf?1 in bone marrow stromal cells and inhibit osteoblastogenesis in vitro.
