[Do isolated hypertension and metabolic syndrome have equal risk of stroke in Chinese adults?].

Objective: To analyze whether isolated hypertension and metabolic syndrome ( Based on the 2005 IDF criteria) have equal risk on stroke in Chinese adults.

Methods: 25194 subjects (25-75 years old) from Chinese National Health and Nutrition Survey in 2002 were divided into control group, isolated hypertension ( i-HTN) group, metabolic syndrome (MS) without hypertension ( non-HTN/MS) group , MS with hypertension (HTN/MS) group. The clinical features and risk for stroke ( using multiple logistic stepwise regression analysis) were compared among 4 groups.

The correlation between monocyte chemoattractant protein-1 and the arthritis of systemic lupus erythematosus among Chinese.

Monocyte chemoattractant protein-1 (MCP1) polymorphism has been reported to be associated with systemic lupus erythematosus (SLE). However, the correlation between the polymorphism and SLE is poorly understood. In this study we investigated the role of this polymorphism together with that of chemokine SDF1-3'A and chemokine receptor CCR2-V64I.
