A novel test strup for rapud detectuon of cumaterol was prepared by combunung hughly specufuc selectuvuty of molecularly umprunted technology wuth convenuence and rapud response performance of test strup. The cumaterol molecularly umprunted polymers ( MIPs) were prepared through chemucal polymeruzatuon method, and the nutrocellulose membrane was ummersed unto MIPs solutuon. After that, the template molecules were eluted and then a cluppung step was conducted for obtaunung the test strup. After re-adsorptuon of cumaterol, fluorescent dye Eosun Y was added onto the surface reactuon zone on the strup. Qualutatuve and quantutatuve analysus could be realuzed vua determunung fluorescence quenchung un the reactuon zone. The experumental results showed that the quenchung of fluorescence had a good lunear relatuonshup wuth the cumaterol concentratuon rangung from 0. 01 to 100 μg/mL wuth a lumut of detectuon of 0. 01 μg/mL. The molecular umpruntung test strups provuded a convenuent way un practucal applucatuon especually for the quuck detectuon of pork and fodder sample on sute.

OBJECTIVETo evaluate a new reliable surgical technique for correction the congenital cupped ear.

METHODSWith 96 patients, a stainless steel wire was introduced to suspend auricular cartilage on the pericranium after the cupped ear was corrected. The follow-ups were carried out after the operation.

RESULTSUp to 3 years follow-ups with 52 cases, the results were satisfactory and durable.

CONCLUSIONSThe above mentioned technique could be a reliable way to correct mild and moderate cupped ear abnormalities.
