RESUMO
To investigate the distribution of traditional Chinese medicine (TCM) Syndromes of diabetic retinopathy and explore the correlation between various symptoms. Based on the literature in databases of China Journal Full-text Database (CNKI), Wanfang database, VIP network, China biomedical literature database (CBM) and PubMed, SPSS 20.0 and IBM SPSS Modeler 14.1 software were used to analyze the location of disease, symptoms, tongue and pulse, and syndrome type distribution through frequency statistics. In addition, association rule algorithm was used to explore the basic rules for underlying symptoms combinations of diabetic retinopathy. A total of 560 articles were retrieved, and a total of 240 articles met the inclusion and exclusion criteria. In these documents, 62 types of TCM syndromes were found, involving 9 820 cases, 201 symptoms, 29 tongue conditions, and 36 pulses conditions; the first two locations for the disease were liver and kidney. Then the association rule analysis of high frequency symptoms was used to dig out 15 groups of latent syndrome, and 3 underlying symptom combinations among high frequency symptoms, tongue conditions and pulse conditions. The results of the study showed that Qi and yin deficiency was most common for the diabetic retinopathy, and the location of the disease was closely related to liver and kidney. In addition, these high-frequency symptoms and tongue conditions, pulse conditions, and underlying symptom combinations can occur as main symptoms at diagnosis, providing reference for us to study the epidemiology of PRO scale of the disease. They can also increase the weight of these symptoms directly as the main symptoms, which can be also used as an alternative entry pool for TCM syndrome diagnostic scale, laying foundation for the construction and optimization of TCM symptom database of diabetic retinopathy.
RESUMO
Objective To study general law of typing according to syndrome differentiation of Chronic Obstructive Pulmonary Disease (COPD). Method Based on large sample prospective Clinical Epidemiology investigation, symptoms, conditions of tongue, pulse according to TCM and pulmonary function, quality of life in 616 patients of COPD were collected. By means of Frequencies procedure, factor analysis, cluster analysis and analysis of variance in SPSS11.5, analyze the investigated data and lay difficient types of syndrome of COPD according to TCM. Meanwhile, explored distinct distribution and the relation between types of syndrome and pulmonary function, quality of life in patient5 with COPD. Result There were six types according to syndrome differentiation of COPD, deficiency of lung-qi, pathogenic wind-cold attacking lung, deficiency of pulmonosplenic both vital energy and yin, yin-deficiency of the lung and kidney, stagnation of phlegm and pathogenic fluid-reteneion in lung following splenic asthenia and stagnation of liver-qi, blood stasis-phlegm following deficiency of heart-yang and kidney-yang. There were multiple types of syndrome in COPD patients, the relation was detected between each type of syndrome and lung function, quality of life. Conclusion To draw assistance from clinical epidemiology and mathematical statistics method, the initial standard of differentiation of symptoms and signs to COPD was layed. The regularity of types of syndrome to COPD was detected. The result could be used in diagnosis of COPD, and the method could be communicated in the standardization research of syndrome differentiation.
