Objective:To obtain the core traditional Chinese medicine (TCM) syndrome elements and western medicine physical examination indexes of sub-health population through complex network analysis, and to provide multi-dimensional clinical basis and reliable methods for distinguishing TCM excess syndromes in sub-health population. MethodAccording to the classification criteria of health status, we screened 233 cases of sub-health status diagnosed with TCM excess syndrome, including 105 cases of qi stagnation syndrome, 69 cases of blood stasis syndrome, 34 cases of phlegm-dampness syndrome and 25 cases of excess heat syndrome. The complex network analysis was used to analyze the core network relationship between TCM syndrome elements of each syndrome and western medicine physical examination indexes.  Results:①The core syndrome elements of Qi stagnation syndrome were epigastric stuffiness and distension, distending pain of chest and hypochondrium and thick coating, etc. The core physical examination indexes of western medicine were abnormal diastolic blood pressure and monocyte level. The associated nodes of the two groups of items were epigastric stuffiness and distension, belching, thick coating, fatigue and abnormal diastolic blood pressure. ②The core syndrome elements of blood stasis syndrome were pale purple tongue, white coating and thin left pulse, etc. The core physical examination indexes of western medicine were abnormal systolic blood pressure, basophil level and platelet distribution width, etc. The associated nodes of the two groups of items were pale purple tongue, white coating, wiry left pulse, thin left pulse, abnormal systolic blood pressure, diastolic blood pressure, basophilic granulocyte level, platelet distribution width and monocyte level. ③The core syndrome elements of phlegm-dampness syndrome were greasy coating, dizziness and insomnia, etc. The core physical examination indexes of western medicine were abnormal body mass index (BMI), uric acid and total cholesterol, etc. The associated nodes of the two groups of items were yellow coating, thick coating, greasy coating, abnormal systolic blood pressure, monocyte level, platelet distribution width and body mass index. ④The core syndrome elements of excess heat syndrome were gingival swelling and pain, yellow coating and constipation, etc. The core physical examination indexes of western medicine were abnormal BMI, systolic blood pressure, monocyte level, etc. The associated nodes of the two groups of items were constipation, yellow coating, abnormal systolic blood pressure, diastolic blood pressure, basophil level and monocyte level.  Conclusion:The complex network analysis can be used to find the core TCM syndrome elements and core western medicine physical examination indexes in sub-health population with different excess syndromes, and to provide more accurate and multi-dimensional basis for distinguishing TCM excess syndromes in sub-health population. Specific physical examination indexes corresponding to different TCM syndromes are helpful to find abnormal manifestations of sub-health population from the perspective of western medicine, which may further help early intervention to reduce the risk of suffering from certain diseases.
