摘要
目的:探讨2017年广州地区冬季乙型流行性感冒病例的流行病学、中医证候学特点。方法:采用横断面调查方法分析广州地区2017年12月至2018年2月收集的244例乙型流行性感冒病例的流行病学特点,结合其中医证候学资料,总结中医证候分布规律。结果:2017年冬季乙型流行性感冒患者就诊时以发热、恶寒、咳嗽、鼻塞为主要症状,证候以风热袭表证为主(38.11%),其次为风寒束表证(31.56%)、表寒里热证(26.23%),热毒袭肺证及气虚外感证少见。风热袭表证,夹湿者17例(18.09%),风寒束表证,夹湿者8例(10.39%)。2例气虚外感证患者年龄均≥65岁,表明中老年患者正气不足情况较青壮年发病高,其他不同年龄段的乙型流行性感冒病例的证候特点未见明显差异;不同病程之间证候构成比未见明显差异。结论:广州地区2017年冬季乙型流行性感冒,青壮年发病率更高,以中高热为主要临床症状,以风热袭表证、风寒束表证、表寒里热证为主要证型。
Objective: To investigate the epidemiology and TCM syndrome characteristics of patients infected with influenza B virus in Guangzhou in 2017 winter.Methods: A total of 244 patients infected with influenza B virus were respectively observed during December 2017 to February 2018 in Gaungzhou.Epidemiological features and the characteristics of TCM syndromes were summarized.Results: Fever, cold, cough and nasal congestion were the most common symptoms in the winter of 2017; Followed with wind-heat type was the major syndrome,accounted for 38.11%.Wind-cold type(31.56%) and cold-heat type(26.23%); Hot poisonous lungs type and Qi deficiency type are rare. Among those syndromes, wind-heat type and cold-heat type were tend to combine with dampness, and there were 17 cases and 8 cases, accounting for 18.09% and 10.39% respectively. Two patients with exogenous Qi deficiency type occurred in the age group of ≥65 years old, indicating that exogenous Qi deficiency type in middle-aged and elderly patients was higher than that in young adults; And there are no significant differences in the syndrome characteristics of other influenza B cases of different age groups. There was no significant difference in the composition of syndromes between different disease courses. Conclusions: The influenza B is higher incidence in younger adults in the winter of 2017, in Guangzhou. The main clinical symptoms were moderate-high fever. The wind-heat type, wind-cold type and cold-heat type are the main types of syndrome.
