A Newcastle disease virus(NDV)field strain SGM01 was isolated from a broiler flock in high antibody level against NDV,and identified by HA,HI cross test and animal regression.SGM01 was determined as a virulent strain with MDT of 50.5h,ICPI of 1.76,IVPI of 2.41 after plaque-purification.The F and HN gene of SGM01 were cloned and sequenced.Analysis of F gene indicated that SGMOI be- longed to genotypeⅦ.The amino acid sequence ~(111)GGRQGRL~(117) in the F protein cleavage site in SGM01 strain is identical to virulent NDV. The homology analysis of F and HN gene sequences compared to reference strains from GenBank indicated that:The F protein amino acid se- quence has homologies of 87.7%～88.3% with published gene typeⅡstrains LaSota and SQZ04 et al.,95.7%～98.2% with genotypeⅦstrains Taiwan95,Yunnan03 et al.,91.8%～91.7% with genotypeⅨstrains F_(48)E_9 et al..Willie HN genes were compared,SGM01 demonstrated a higher homologies of 96.5%～97.2% with strains which were isolated in recent years,but lower homologies of 87.4% and 89.0% with LaSota and F_(48)E_9.

OBJECTIVE:To evaluate the cost-effectiveness of 3 therapeutic regimes in the treatment of functional dyspepsia. METHODS:125 cases were randomly divided into 3 groups,group A was treated with domperidone,group B was treated with domperidone plus doxepin hydrochloride,and group C was treated with domperidone plus famotidine,the curative effects of the 3 group were observed after oral administration and the cost-effectiveness analysis was conducted as well. RESULTS:The costs for group A,B and C were 792.56 yuan,800.12 yuan and 803.76 yuan,respectively;The effective rates were 51.17%,82.50%and 71.43%,respectively;The cost-effectiveness ratio were 15.49,9.70 and 11.25,respectively;The incremental cost-effectiveness ratios of group B and C vs. group A were 0.24 and 0.55,respectively. CONCLUSION:Regime B was superior among the other two therapeutic regimes.
