The Use Of Factor Analysis In Patients With Acute Ischemic Stroke Syndromes Distribution

BackgroundStroke as the major diseases of modern society, its control and related basic research has been the focus of the State support. The syndrome of stroke as a basis for the study of stroke patients, the core research in the field of Chinese medicine is always hot and difficult. Syndrome of the key problems is how to objectively and accurately grasp the stroke syndrome characteristics at different time points, namely, the dynamic space of the syndrome, and such features simple, straightforward way to express them. According to syndrome of the present situation of research design and the number using modern statistical methods, to carry out syndrome factors of ischemic stroke related research, establish an objective, standardized, uniform diagnostic criteria for evidence-based, Chinese medicine is to establish a standardized program of prevention and treatment of stroke patients important way. Research objects and MethodologyIn this paper, fifteen national science and technology research, "Differentiation of acute ischemic stroke model specification and evaluation of efficacy" (the mission statement No.:2004BA721A02) specification part of the dialectical basis, to March 2005 to October 2006 the country during the period of 23 consecutive admissions Clinical neurology unit at home, emergency, acupuncture and other outpatient and inpatient acute ischemic stroke patients to 1 to 3 days after onset, and 4 to 11 days,10 to 30 days after onset Total 3 survey time points, respectively, Total of 4077 cases. Exploratory factor analysis using statistical methods to explore the acute ischemic stroke syndrome factors such as distribution and evolution of law. Application SPSS17.0 statistical software for statistical analysis.Research Result: By using factor analysis and calculation of factor scores obtained in the 3 survey time cases of acute ischemic stroke syndrome factors distribution. Onset of acute ischemic stroke syndrome factor 1-3 days after the distribution of certificates for the fiery 18%,29% phlegm,22% of qi deficiency, yin deficiency of 23%,8% of blood stasis; after the onset of 4-10 days The distribution is the fiery 23%,34% phlegm,15% of qi deficiency, yin deficiency 19%,9% of blood stasis; In 11-30 days 23% for the hot cards, accounting for 25 phlegm%,10% of qi deficiency, yin deficiency of 32%,11% of blood stasis; analysis of the results of three surveys, the incidence of acute ischemic stroke syndrome of 1-10 days, the main elements is phlegm, fire certificates; incidence of 11-30 days, the main Elements is the Yin deficiency syndrome; Conelusion:1. Phlegm, fire certificate is the main elements in patients with acute ischemic stroke onset syndrome 1-10 days. Incidence of 11-30 days, phlegm, the proportion of hot cards began to fall, the proportion of yin deficiency began to increase, yin deficiency that may be the major syndrome factors of the recovering from ischemic stroke.2. This study of patients with ischemic stroke syndromes is accessing to the distribution and characteristics of clinical symptoms, the study of ischemic stroke prevention and treatment of Chinese medicine has clinical significance.
