不明原因发热是临床诊疗中的难点,患者常以发热为主诉就诊,伴随症状和体征一般不典型,现代医学对于不明原因发热发病机制的研究尚无统一定论,治疗仍以经验性抗炎为主,存在诊断延迟、治疗方案有限、治疗效果欠佳、不良反应明显等不足.中医认为,不明原因发热总属脏腑功能失调,阴阳失衡,具有病程长、病因不明、病情复杂、反复发作、缠绵难愈的特征.李创鹏主任医师基于六经辨证体系,指出不明原因发热的病机特点为少阴阳明合病,提出"温少阴,通阳明"的论治观点,即运用大黄附子汤合薏苡附子败酱散退热祛邪,以细辛引药直达少阴病所,同时健运脾胃、养阴生津、通调血脉,使邪去正安.
Fever of unknown origin(FUO)is a difficulty in clinical diagnosis and treatment.Patients with FUO come to seek medical consultation usually with fever as the main complaint,and the accompanying symptoms and signs are generally atypical.The pathogenesis of FUO remains conflicting in the field of modern western medicine,and its treatment is still focused on empirical anti-inflammatory management,which has the deficiency of delayed diagnosis,limited therapeutic options,poor therapeutic effects,and obvious adverse reactions.In the field of traditional Chinese medicine(TCM),FUO generally results from the dysfunction of zang-fu organs and the imbalance of yin and yang,and has the clinical features of long duration of illness,unknown etiology,complexity of illness,recurrent attacks,and difficult to be cured.Based on the six-meridian syndrome differentiation,Chief Physician LI Chuang-Peng pointed out that the pathogenesis of FUO is characterized by the combined disease of shaoyin and yangming,and put forward the therapeutic principle of warming shaoyin and unblocking yangming.He proposed the use of Dahuang Fuzi Decoction(mainly composed of Rhei Radix et Rhizoma and Aconiti Lateralis Radix Praeparata)plus Yiyi Fuzi Baijiang Powder(mainly composed of Coicis Semen,Aconiti Lateralis Radix Praeparata and Patriniae Herba)to subside fever and eliminate pathogen,together with Asari Radix et Rhizoma for guiding the medicine directly to the shaoyin.Moreover,therapies of strengthening and activating spleen and stomach,nourishing yin to produce fluid,and unblocking the blood vessels can be used for eliminating the pathogen and supporting the healthy qi.
