境外输入新型冠状病毒奥密克戎变异株感染患者的中医证候特征

Characteristics of traditional Chinese medicine syndromes in overseas imported patients infected with Omicron,variant strains of novel coronavirus

[目的]分析境外输入新型冠状病毒奥密克戎变异株感染患者的中医证候特征,为该病的防治提供临床依据。[方法]以2021年12月22日—2022年1月9日收治于天津市海河医院的境外输入感染奥密克戎变异株的华裔患者为研究对象,收集、分析患者的一般情况、呼吸系统症状、全身症状、舌象、肺部计算机断层扫描(CT)表现及中医证候。[结果]43例患者中男性居多,主要来自美国和菲律宾,其中无症状型占13.95%、轻型占44.19%、普通型占41.86%,无重型及危重型。对43例患者进行按病程分析,结果表明,发病初期,以瘟邪袭卫证为主,逐渐演变为热毒犯肺证和湿蕴脾胃证,后期以气阴两虚、湿邪留恋为主。肺部CT表现主要以单肺病变为主,其中磨玻璃样阴影较为常见。[结论]与2020年天津地区新型冠状病毒肺炎相比,奥密克戎具有传染性强,临床症状较轻的特点。

[Objective]To analyze the characteristics of traditional Chinese medicine(TCM)syndromes in overseas imported patients infected with Omicron,variant strains of novel coronavirus,and provide clinical evidence for the prevention and treatment of the disease.[Methods]Overseas imported ethnic Chinese patients infected with Omicron admitted to Tianjin Haihe Hospital from December 22th,2021 to January 9th,2022 were selected as the research subjects.The general conditions,respiratory symptoms,systemic symptoms,lung CT manifestations,states of tongue and TCM syndromes of the patients were collected and analyzed.[Results]Most of the 43 patients were male,mainly from the United States and the Philippines,of which the asymptomatic type accounted for 13.95%,the mild type accounted for 44.19%,the common type accounted for 41.86%,and there were no severe and dangerous types.According to the course of disease,43 patients were analyzed,and the results showed that in the early stage of onset,the main syndrome was plague invading the defensive exterior,gradually evolved into heat toxin attacking the lung syndrome and dampness obstructing spleen-stomach syndrome,and in the later stage,the main syndrome was deficiency of qi and yin and nostalgia for dampness.Lung CT manifestations were mainly single lung lesions,in which ground glass shadows were more common.[Conclusion]Compared with novel coronavirus pneumonia in 2020,Omicron is characterized by strong infectious and mild clinical symptoms.
