目的：了解甲型H1 N1流感病毒的流行特点及传播规律，加强对流感大流行的防控。方法：收集2009年10～12月吉林大学第一医院住院发热门诊中具有流感症状患者的临床样品（鼻咽拭子和血清），采用血凝抑制法、巢式 RT-PCR技术检测具有流感症状患者血清标本中的特异性抗体、咽拭子中的甲型H1N1 RNA 等指标。结果：结果56份流感患者的咽拭子经核酸检测，甲型流感NP和M的阳性率分别为37.5％和27.8％，而甲型H1N1的阳性率仅为3.6％。通过血凝抑制实验结果表明：在相应的血清标本中，能特异性抑制甲型H1N1流感病毒红细胞凝集的样品为27份，抗体均大于1∶320，其中8份样品抗体效价大于1∶5120。恢复期的血清效价与急性期相比有显著的抗体差异，甲型H1 N1病毒特异性抗体阳性率为48.2％，明显高于核酸的检测。结论：核酸检测可在感染早期（排毒期）进行检测，而血清学的抗体检测多用在感染中后期（抗体产生）检测，两者联合可提高甲型H1 N1流感的检出率。

H1N1 influenza A spread around the world in 2009.There were lots of patients in China too.We did this research to know the epidemiological feature and transmission route and strengthen the prevention and control measure of the influenza.Methods:We collected the nasopharyngeal swab and serum samples of 56 patients who had flu symptom from the infectious disease department of 1st hospital of Jilin University from October in 2009 to December in 2009.The specific antibody of the serum samples were detected by the blood clots suppression method and the H 1N1 RNA of the nasopharyngeal swab was detected by the Nest-RT-PCR assay.Results:The results of nucleic acid test showed that 21(37.5%) and 16(27.8%) samples were found NP and M of influenza A positive respectively and only 2 ( 3.6%) were found H1N1 of influenza A positive.The results of the blood clots suppression method showed that the serum samples of 27 patients (48.2%) could suppress the red blood cells blot of H 1N1 influenza A specifically and all the antibody titer was more than 1∶320.The antibody titer was more than 1∶5 120 in 8 of them.There′s significant difference of the serum antibody titer between the recovery phase and the acute phase.The specific H1N1 influenza A antibody of 27 (48.2%) serum samples in the recovery phase were positive and it was much higher than the result of nucleic acid test .Conclusion:The nucleic acid could be detected in the acute phase and the serum antibody detection could be done in the later stage .Using both the assays could increase the positive rate of H 1N1 influenza.
