中文摘要：

慢性疲劳综合征（Chronic Fatigue Syndrome，CFS）的发病原因及机理至今还未得到统一的标准和答案，其诊断大多是患者的主观自我感受，缺乏临床的客观指标，这就造成了诊断的困难和治疗的针对性。临床上很难区分慢性疲劳综合征和其它类型疲劳之间的差异，以致很多人把普通的疲劳误认为是慢性疲劳综合征，从而夸大了病情，造成了不必要的心理负担。目前人们在研究慢性疲劳综合征发病原因和机理时，往往更加关注病理生理上的改变，但不同社会环境和职业对患慢性疲劳综合征的影响则仍有争议，因此人们对慢性疲劳综合征的正确认识有待更进一步的提高，不同的社会环境和职业对慢性疲劳综合征的影响有待更加深入的研究。

英文摘要：

The causes of chronic fatigue syndrome and its mechanism has not yet been unified standards and answers,its diagnosis mostly is patient＇s subjective self--feeling, lacks the clinical obj ective indicator, which caused the difficulty of diagnosis and treatment targeted. It＇s difficult to distinguish the differences between chronic fatigue syndrome and other types of fatigue, so many people mistakenly think that a common fatigue is chron- ic fatigue syndrome, thus exaggerating the condition of illness, causing an unnecessary psychological burden. At present, people pay more attention to pathophysiological changes when they are researching the causes and pathogenesis of chronic fatigue syndrome,most people think that the immunity disorder and the nerve internal secretion are the latent reasons,and different social environment and occupation on the impact of chronic fatigue syndrome is still being debated. So the correct understanding of chronic fatigue syndrome to most people should be further improved,different social environmental and occupational impact of chronic fatigue syndrome should be more in--depth study.
