[Objective] To evaluate the clinical efficacy of treatment of humeral shaft fracture with revolving intramedullary nails.[Method]Sixty-two cases with fracture of hume ral shaft were treated by revolving intramedullary nails between January 2000 and February 2006.Their were 38 male cases and 24 female cases.Their average age was 36.9(ranged 20～58).Fifty-fous cases were closed fractures,and eight cases were opened.Sixty-two cases with fracture of humeral shaft according to AO classification,41 cases were type A,15 cases were type B,6 cases were type C.Sixty-two patients with the humeral shaft fracture were treated with limited open reduction and minimally invasive internal fixation with revolving intramedullary nails.Scientific and rational rehabilitative treatment was carried out in each case after the operation.All patients were follow-up between 14 months and 30 months.The average follow-up period was 24 months.[Result]The fracture union occurred in sixty-two patients.The average healing time was 15 weeks.According to Rodriquez-Merchang shoulder functional score system,the excellent result was achieved in 36 patients,good in 20 and fair in 6.The excellent and good rate was 90.3%.All cases got good function recovery.The effects were satisfactory.There were no complications in all cases,such as infection,iatrogenic fracture,shortening,break of nail,fat embolism syndrome and peripheral nerve injury.[Conclusion]Revolving intramedullary nails for treatment of humeral shaft fracture is effective with litter interference with the blood supply of the bone fracture and with stable immobilization.Due to the abutment of the longitudinal bars along the entire length of the medullary canal wall,highly resistant to the rotational strength was achieved.The advances of revolving intramedullary nails are convenient in operative procedure with little invasive of operation,early function exercise,high raito of fracture healing and safety compared with the normal operative therapy.The operation indication and timing should be controlled strictly.The manipulation should be familiar.This kind of treatment is worth to be recommended.

Object To study the causes for the occurrence of red skin and dark green skin of Panax quinquefolius L. during processing and its mechanism. Methods To observe the phenomena and analyze the result which simulated the processing condition of P. quinquefolius based on its components. Results The cross section of P. quinquefolius began to appear light red at 40 ℃, lasting 72 h. Whereas the time of browning was shortened with the temperature rising. The cross section of P. quinquefolius turned green while dipping in solution of Fe 3+ ion of 0 01 mol/L for 25 min. The time of turning green was shortened with the increasing concentration of Fe 2+ , Fe 3+ solution. Conclusion The results show that red skin of P. quinquefolius was caused by the Maillard reaction while drying at the excessive higher temperature. Whereas the complex reaction between phenolic substances in P. quinquefolius and metal ions during processing might result in dark green skin of P. quinquefolius. This expounds the mechanism of red skin and dark green skin turning during the P. quinquefolius processing in the theory.

Objective:To investigate the effects of various bio-adhesive polymers on bio-adhesive characteristics and release rate of 5-fluorouracil HP-β-CD inclusion complex thermo-sensitive gels. Methods: Bio-adhesive polymer, such as hydroxypropylmethylcellu-lose ( HPMC) , sodium alginate ( SA) , sodium hyaluronat ( HA) ,carbopol and polycarbophil was respectively used to prepare the ther-mo-sensitive gels, and the bio-adhesive force was studied. The phosphate buffer (pH 7. 2) was used and the drug release characteris-tics were studied using dialysis technique. Results: The bio-adhesive force of the gels with 0. 2% polycarbophil was 32. 3 g·ml-1 , and the drug release time was prolonged to 8 h. There was no obvious difference in the dissolution among the gels with the various bio-adhesive polymers. Conclusion:Using 0. 2% polycarbophil as the bio-adhesive polymer, 5-fluorouracil HP-β-CD inclusion complex thermo-sensitive gels show good bio-adhesive force and prolonged drug release characteristics.
