10、 cohort study. Average age is 6610.8 years, and female is 1260(64%)；male is 720(36%). All subjects underwent routine blood examinations, insulin, remnant like particle cholesterol (RemLC), hs-CRP, cystatin C, plasma brain natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) measurements. Bloo
11、d pressure, abdominal circumference, and electrocardiography were measured at the same time. Abdominal circumference was measured at the navel level in the supine position like CT for visceral fat. Evaluation of cholesterol absorption was done by plant sterols in each 30 participants chosen randomly
12、 from the participants. BNP and NT-proBNP were measured for heart failure screening by immunoluminesence method. Plant sterols were measured by gas chromatography.The 4th Shino-Japan Cardiovascular Forum on October 23-24, 2008 in Beijing In 1964 participants, 218 participants(11%) were diagnosed as

31、sterol 5%, high triglyceridemia 18%, high blood sugar 17% and in women, abdominal circumference 90cm 10% and 80cm 44%, respectively. According to Japanese abdominal circumference criteria for MS in women, only 3% of women were diagnosed as MS. Using 80cm as criteria for abdominal circumference, 10%
32、were diagnosed as MS. In men (85cm), 13% were MS. Participants with possible cardiac dysfunction were 46% in BNP and 52% in NT-proBNP, respectively. RemLC was very closely related to MS. Receiver operating characteristic (ROC) curve analysis for diagnosing MS demonstrated that cut-off value of LemLC

34、bsorption of cholesterol marker levels were paradoxically lower in MS than in non MS. Lathosterol, a marker of cholesterol synthesis was 2.4g/mL in MS and 2.8 g/mL in non MS (p=0.1133), sitosterol, a marker of cholesterol absorption 1.5 g/mL in MS and 1.8 g/mL in non MS (p=0.0107), campesterol, a ma
35、rker of cholesterol absorption, 2.4 g/mL in MS and 2.8 g/mL in non MS (p=0.1551). CKD was found in 9.5% of the participants using MDRD.The 4th Shino-Japan Cardiovascular Forum on October 23-24, 2008 in Beijing ConclusionMS was found in about 10% in general population of Japan. Absorption cholesterol
36、 marker, plant sterols were paradoxically lower in MS than in non MS and then abnormal absorption was strongly suspected in MS. In other words, low plant sterol levels may implicate increased cholesterol absorption in the small intestine. RemLC may be a useful single marker for screening of MS. Pres
37、ent Japanese criteria for MS should be modified correctly as early as possible. We need more detail investigation for more clarification on MS.The 4th Shino-Japan Cardiovascular Forum on October 23-24, 2008 in Beijing Thank you very much for your attention(Beijing Olympic Year)The Lake Shinji, Shimane
