Results 1.1372 TB cases were enrolled project,916 new cases and 456 previously treated cases,2.Primary resistance(PR)to any drug was found 43 0%,Acquired resistance(AR)to any drug was 68 2%,total resistance rate 51 4%. 3. Any primary resistance SM,32 5%;INH,31 0%;RIF,20 7% and EMB,10 3%.and any acquired resistance SM,52 2%;INH,49 3%;RIF,48 3%;and EMB,20 4%. 4.Multi_drug resistance rate primary 16 5%,Acquired 37 1%. 5.PR and PMDR in never use drug group is 35 0% and 10 9%,far less than that in using drugs<1 month group 66 1%and 25 3%( P <0 01).6. >60 years group,PR and AR is 39 1% and 58 4% far less than average rate 43 0% and 68 3%.7.The cure rate of new cases all sensitive group,mono_drug resistance and multi_drug resistance was 64 3%,59 6%,49 8% and of old cases,50 0%,37 7%,35 8%.Conclusion Drug resistant TB was found highly prevalent in Henan and the cure rate remained poor.The finding urges to take immediate action to improve cure rate.展开更多
