Abstract： Objective： To observe the clinical characteristics of patients with stroke- associated pneumonia(SAP)， summarize the characteristics of Chinese medicine syndromes of the disease，and analyze the correlation between Chinese medicine syndrome differentiation and clinical characteristics and modern detection indexes of patients with SAP. Methods：A total of 98 patients with SAP admitted to Ninth People's Hospital of Zhengzhou from February 2017 to February 2020 were selected. The general clinical data of patients were collected， and characteristics of Chinese medicine syndromes of the disease were summarized and classified. The correlation between the examination results of blood routine，sputum culture and the Chinese medicine syndromes of SAP was analyzed. Results： The contents of white blood cell(WBC) in 43.9% of patients were increased，and 60.2% of patients had positive sputum culture. The Chinese medicine syndromes in patients， according to the distribution proportion from high to low，were syndromes of heat entering the pericardium，phlegm- heat obstructing the lung，wind-heat attacking the lung，phlegm-damp obstructing the lung，sinking of pathogen and healthy qi desertion，external cold and internal heat，lung-spleen qi deficiency，and deficiency of both qi and yin. There were relatively strong correlations between syndromes of heat entering the pericardium and phlegm-heat obstructing the lung and cerebral infarction，and between the syndromes of wind-heat attacking the lung and phlegm-damp obstructing the lung and cerebral hemorrhage. There were relatively strong correlations between the syndromes of wind- heat attacking the lung， phlegm- heat obstructing the lung and sinking of pathogen and healthy qi desertion and WBC<4×109/L. There were relatively strong correlations between the syndromes of phlegm-damp obstructing the lung and heat entering the pericardium and WBC>×109/L. The results of sputum culture showed that there were relatively strong correlations between syndromes of sinking of pathogen and healthy qi desertion，wind-heat attacking the lung，phlegm-heat obstructing the lung and heat entering the pericardium and the positive rate. Conclusion：The most common syndromes of SAP are the syndromes of heat entering the pericardium，phlegm-heat obstructing the lung，wind-heat attacking the lung and phlegm-damp obstructing the lung，and there are strong correlations between them and modern detection indexes such as WBC and sputum culture. Therefore， modern indexes such as WBC and sputum culture can be used to differentiate the clinical syndromes.
