【摘要】目的 探讨本地区甲/乙型流感病毒在不同流行季节的变化趋势,分析流感病毒阳性患者外周血细胞中白细胞(WBC)、中性粒细胞(Neu)、淋巴细胞(Lym)、嗜酸性细胞(Eos)、血小板(PLT)和C反应蛋白(CRP)等感染性指标的变化。了解季节因素对流感病毒传播的影响,为流感病毒的临床治疗及疾病预防提供流行病学依据。方法利用胶体金标记免疫层析技术进行流感抗原的检测,对2017年3月至2018年2月检测的1648份流感病毒抗原筛查结果进行统计学分析,分析其流行病学特征,包括季节、年龄段分布特点。同时分析流感病毒阳性病例的相应血常规和CRP等感染性指标的变化。结果 与正常对照组比较,流感组CRP明显升高,WBC、Eos、Lym、PLT则明显下降,差异均有统计学意义(P<0.05)。2017-2018年度,本地区流感高峰期在2018年1~2月,且以乙型流感为主,其余月份为散发低流行。年度甲型流感和乙型流感病毒检出率比较,差异有统计学意义(χ2=20.615,P<0.05)。不同年龄组的流感病毒抗原检出率比较差异有统计学意义(χ2=27.174,P<0.05)。结论 流感病毒的流行与季节有着密切的关系,本地区流感的类型在不同的流行季节存在着一定的变化趋势。甲型/乙型流感病毒抗原胶体金法具有快速、简单准确和无污染等优点,适合基层医院广泛筛查使用。

【Abstract】Objective To discuss the trend about influenza antigen in different seasonal in Shaoxing area,meanwhile to detect and analyze the variety about WBC,NEU,LYM,EOS,PLT and CRP in patients which infected by influenza. To master and understand the influence about seasonal factor to influenza virus transmission,and in order to provide the epidemic foundation for clinical treatment and disease prevention. Methods The immunochromatogragphic assay was used to detect the 1648 patient's influenza virus antigen from March 2017 to February 2018 which were diagnosed and detected in our hospital. The data were analysis using SPSS,the epidemiological characteristic and the factor such as seasonal and age were also analyzed. Results Compared with the normal group,the CRP in the influenza group were higher than the normal group,and WBC,EOS,LYM,PLT were significantly decrease(P<0.05).From 2017 to 2018,the peak period of influenza was in January and February in 2018,and the mainly type was influenza B,the other months were low epidemic period. Compared with the influenza virus type A and B in the total year,there was statistical significance between them(χ2=20.615,P<0.05). The influenza virus antigen prevalence in different age group were also showed statistical difference (χ2=27.174,P<0.05). Conclusions The epidemic of influenza virus is closely related to the season. The types of influenza in this region have a certain change trend in different epidemic seasons. Colloidal gold assay for influenza A/B virus antigen has the advantages of rapidity,simplicity,accuracy and non-pollution. It is suitable for extensive screening in grass-roots hospitals.

流行性感冒病毒(Flu)是引起全球性流行性感冒的病原体,病毒为正粘病毒科,单负股RNA病毒,通过飞沫传播[1]。人类流感病毒主要分为甲、乙、丙三种类型。对于甲型和乙型流感病毒检测具有较大临床意义,而丙型流感病毒主要侵袭婴幼儿,且以散发出现,一般不引起流行[2]。为了解近期本地区流感病毒随不同季节的流行情况,作者对1648例疑似患者进行流感病毒抗原的筛查检测,现报道如下。
