【摘要】 目的：分析北京市延庆区2018—2020年流行季流感样病例的病原学检测结果及中医证候特征，为今后北京地区流感的中医防治提供参考依据。方法：采集北京市延庆区医院2018—2020年流行季流感样病例，进行病原学检测，并将2018—2019年流行季及2019—2020年流行季属于自然病程的流感样病分别选取583例及571例，置于综合了六经、卫气营血、三焦辨证体系的框架中分析中医证候特征。结果：2018—2020年流行季流感样病例分别为3153例和3090例，阳性率为53.6%及51.1%，甲型流感病例占91.4%～99.1%，乙型流感病例开始出现于1月底至2月初。病因方面，发病的始动因素中，风热邪气最多；证候的分布方面，太阳病、少阳病、太阳阳明合病、太阳少阳合病、阳明少阳合病、太阳少阴合病、风热犯肺、燥热犯卫、肺热壅盛、肺胃热炽、卫气同病在分布特征方面差异有统计学意义（P<0.05），太阳病所占比例呈持续下降态势，其余证候均呈现先升后降的态势。三阳合病、太阳少阴合病、阴虚感温、燥热伤肺、肺热腑实及肺热发疹的在分布特征上未见显著差异（P>0.05）。结论：此次调查分析，明确了北京市西北部地区流感的病毒分型规律及中医证候分布规律，总结了六经、卫气营血、三焦辨证联合体系辨证下的中医证候特征，为中医药防治流感提供了前期的证候参考资料。更多还原

【Abstract】 Objective: To provide the reference for preventing and treating influenza with TCM in Beijing by analyzing the results of etiological tests in influenza-like cases during the epidemic season between 2018 and 2020 in Yanqing district of Beijing and the characteristics of TCM syndromes. Methods: The influenza-like cases during the epidemic season between 2018 and 2020 in Yanqing district of Beijing were collected to perform etiological tests, 583 cases and 571 cases of influenza-like disease in the 2018-2019 epidemic season and the 2019-2020 epidemic season were respectively selected, belonging to natural course, to analyze the characteristics of TCM syndromes after putting them in the framework of integrating six meridians, defensive Qi and nutrient blood,syndrome differentiation of three energizer. Results: There were 3, 153 cases and 3, 090 cases of influenza-like disease in the 2018-2020 epidemic season respectively, and the positive rates were 53.6% and 51.1%, and the cases of influenza A holding between 91.4% and 99.1%, while the cases of influenza B began to appear from the end of January to the start of February. The aspects of causes, pathogenic factor of wind-heat was the most among the initial factors of the disease; the distribution of syndromes, the difference was statistically significant in the distribution of Taiyang disease, Shaoyang disease, disease involving Taiyang and Yangming, disease involving Taiyang and Shaoyang, disease involving Yangming and Shaoyang, disease involving Taiyang and Shaoyin, windheat invading lung, dryness-heat attacking defensive, lung heat congestion, lung and stomach excessive heat,disease involving defensive and Qi simultaneously(P<0.05), the proportion of Taiyang disease has continued to decline, and other syndromes presenting the state of first raising and then decreasing. No significant difference has been found in the distribution of disease involving Taiyang, Yangming and Shaoyang, the disease involving Taiyang and Shaoyin, Yin deficiency and invasion of febrile disease, dryness-heat hurting lung, lung heat and solid Fu-organs, and rash caused by lung heat(P>0.05). Conclusion: The investigation has confirmed the classification law of influenza in northwest region of Beijing municipality, concluded the characteristics of TCM syndromes in syndrome differentiation with six meridians, defensive Qi and nutrient blood and three energizer, which could provide the previous reference of syndromes for the prevention and treatment of influenza with TCM.更多还原
