摘要: 目的  探讨新型冠状病毒肺炎(novel coronavirus pneumonia,  NCP)的临床特征及预后。方法  计算机检索 PubMed、万方和CNKI 数据库,收集关于NCP临床特征的研究,检索时限均从建库至2020 年2月20日。结果  共纳入5个横断面列研究,包括436例患者。Meta分析结果显示:NCP主要症状为发热[0.89,95%CI(0.80, 0.97)]、咳嗽[0.68,95%CI(0.51, 0.85)],主要实验室检查特点为淋巴细胞减少[0.60,95%CI(0.43, 0.77)],C反应蛋白(CRP)升高[0.85,95%CI(0.80, 0.90)],降钙素原(PCT)正常[0.76,95%CI(0.54, 0.99)],胸部CT双侧受累为主[0.88,95%CI(0.79, 0.97)]。病死率为9%,95%CI(4%, 14%)。结论  NCP主要累及中老年人,主要临床特征相似,具有较高的病死率。但受纳入研究质量的限制,仍需大样本研究进一步探索。

Abstract: Objective  To explore the clinical features and prognosis of novel coronavirus pneumonia (NCP). Methods  PubMed,  WANFANG,  and CNKI were searched to collect clinic trials involving clinical characteristics of NCP from inception to February 20,  2020. Results  A total of 5 crosssectional studies involving 436 patients were included. The metaanalysis showed that  common clinical characteristics were fever(0.89,95%CI0.80, 0.97),  cough (0.68,95%CI0.51, 0.85),  lymphopenia  (0.60,95%CI0.43, 0.77),  increased Creactive protein (CRP)(0.85,95%CI0.80, 0.90),  normal procalcitonin (PCT)(0.76,95%CI0.54, 0.99)  and bilateral chest CT involvement(0.88,95%CI0.79, 0.97). The case fatality rate was 9%. Conclusion  NCP mainly involves middleaged and elderly people,  with similar main clinical features and high  case fatality rate. However,  further exploration of large sample studies is still needed due to the limitation of the quality of included studies.
