Aim To generate m3AChR-G11 fusion protein in baculovirus-Sf9 cells and test the couping function,the interation and the influence factors be-tween m3AChR and G11 protein,as well as screen the specific ligands for m3AChR. Methods m3AChR-G11 fused DNA was generated through a two-step PCR and then expressed in Sf9 cells to produce fusion protein. The total concentration for membrane protein was de-tected by BCA method,[3H]QNB and [35 S]GTP?S binding experiment as perfomed to study the function of m3AChR-G11 fusion protein. Results The expression level of m3AChR-G11 was 7. 76 ? 10 -9 mol?g -1. The affinity of GDP to G11 partner changed in the presence of different muscarinic ligands. IC50 values of GDP in the presence of ACh,Pilo,CCh,MCN-A-343,Atro,4-Damp and Dafi were 82. 2,93. 70,12. 10,14. 30, 1. 93,1. 37,0. 72 ? 10 -6 mol ?

Objective To evaluate the clinical effect of treatment for deep burn wound on finger by proper digital artery flap.Methods From March 2013 to October 2016, 24 patients with deep burn wound on finger were treated by proper digital artery flap.Postoperative observation included wound repair, flap survival, complications and functional recovery of fingers.Results All the 24 flaps survived and no necrosis happened.The marginal abnormal circulation of flap occurred in only 5 cases, which cured by dress changing.All flaps kept well in contour, skin color, temperature and texture.Movement function of donor and recipient fingers was nearly normal.Conclusion Proper digital artery flap avoided the deficiencies distant pedicled flap, so it is a favorite choice for digital soft tissue defect caused by deep burn injury.

A Cleanert Alumina-N-SPE column (0.5 g/6 mL) chromatograpy with 5 mL of chloroform-methanol (7: 3) as eluent, instead of aluminum oxide column (100-200 mesh, 5 g, 1 cm) chromatograpy eluted successively with chloroform and the chloroform-methanol (7:3) (20 mL each), was applied to enrich matrine and oxymatrine in Sophora flavescens. Also, the optimization of the HPLC determination conditions with acetonitrile-ethanol absolute-3% phosphoric acid solution (84: 6: 10) as mobile phase, instead of acetonitrile-ethanol absolute -3% Phosphoric acid solution (80: 10: 10) recorded in Chinese Pharmacopoeia 2010 Edition, was more suitable for determination of matrine and oxymatrine in S. flavescens. This method has advantage of reducing sample handling time and solvent volume and increasing the accuracy and feasibility, which can simplify the procedure for determination of matrine and oxymatrine in S. flavescens.
