Literature of TCM contains abundant information of Chinese medicine. Traditional Chinese medicine information is characterized by its high degree of knowledge-intensive and complex inter-knowledge, so it is difficult to integrate and share knowledge. TheShanghanlun is one of the Chinese medical classics, and it includes the rules and methods of syndrome differentiation and treatment and it showed good effects in the clinical application. However, it is difficult to master for beginners. As a kind of knowledge organization tool, topic maps can flexibly define the relationship between knowledge, which realizes the visualization of knowledge network, and integrates and shares the distributed knowledge. This paper focused on the current situation of topic maps researches. The topic maps was used to organize the original content ofShanghanlun, construct the concept model of it and explore the specific application of topic maps technology in the field of traditional Chinese medicine.

Objectives To investigate the markers of endothelial injury, adipocytokine and thrombotic activity and explore whether there are cardiovascular disease risk factors in antiretroviral-naive HIV patients. Methods Clinical data and venous blood samples were collected from 43 anti-retroviral naive HIV-infected patients during February -October 2009 in our center, and compared with 17 healthy subjects.Plasma leptin, adiponectin, soluble intercellular adhesion molecule-1 ( sICAM-1 ), D-dimer were measured by ELISA. Four markers and cholesterol, triglyceride, fasting plasma glucose were compared between the two groups. The CD4+ T cells and percentages of CD38, HLA-DR on CD8+ T were determined by flow cytometry and plasma HIV copies were detected with bDNA analyzer among HIV-infected participants.Spearman correlations between the significant markers and CD4+ T cells, CD8+ CD38+/CD8+, CD8+ HLA-DR +/CD8+, HIV viral load were examined among HIV-infected participants. Analyses were conducted by using Stata version 7. Results Thirty-eight of the 43 patients were sexually infected by HIV and the median absolute CD4+ T cell count was ( 133 ± 82 ) cells/μl, HIV RNA was (4. 42 ± 0. 66 ) lg copies/ml. HIV-infected patients, compared with healthy subjects, had lower leptin [11.41 (7.91,14. 53 )μg/L vs 55.31( 16. 49,229.65 ) μg/L, P= 0. 0005], adiponectin [1.79 ( 1.40,4. 00 ) mg/L vs 3.36 ( 2. 92,4. 18 ) mg/L,P =0. 003] and higher sICAM-1 [1.71 (1.11,2.40) mg/L vs 0. 69 ( 0. 57, 0. 80 ) mg/L, P = 0. 0000].No significant differences exist in cholesterol, triglyceride, fasting plasma glucose. For HIV-infected participants, sICAM-1 tended to correlate with CD8+ CD38+/CD8+ and HIV viral load ( r= 0.3378, P= 0.0267;r = 0.3904,P = 0.0096). Conclusion Patients with untreated HIV infection have lower leptin, adiponectin and higher sICAM-1 levels and the relationship of these markers to HIV-mediated atherosclerotic risk requires further study.
