Objective To investigate the relationship between C-reactive protein (CRP) and carotid intima-media thickness in pa-tients with impaired glucose tolerance (IGT). Methods Senan CRP was measured with immunoturhidimetry and the carotid intima-media thickness (CAIMT) was measured using color Doppler in 108 patients with impaired glucose tolerance (IGT) and 80 subjects with normal glucose tolerance(NGT).Then we observed all IGT patients for 3 years using prospective follow-up method, Oral Glucose tolerance test (OGGT) and every index were measured in follow-up 1.5 year and 3 year. Results 2 objects were lost to follow-up. IGT group showed a significant higher CAIMT and CRP compared with NGT group. After follow-up 1.5 year and 3 year, the patients with impaired glucose toler-ance (IGT) were divided into type 2 diabetes (T2DM) group and IGT group based on the level of blood glucose. Both T2DM group and IGT group showed a significant higher CAIMT and CRP, compared with NGT group. The level of serum CRP of T2DM group was higher than that of IGT group, and the level of serum CRP of IGT group was higher than that of NGT group. There were great differences between each group.Linear correlation showed that the level of blood glucose was positively correlated with CRP and CAIMT in T2DM group after follow-up 3 year. CAIMT was positively correlated with the level of blood glucose and CRP. Mulfivariant stepwise regression showed that CRP was signifi-canfly correlated with the level of blood glucose and CAIMT. Conclusion Inflammation played an important role in the development of dia-betes, and it had great vessels complication. The patients with impaired glucose tolerance, who have high level of CRP, were facilitated to be diabetes, and they were at risk of getting great vessels complication during the phase of impaired glucose tolerance. So it would be helpful to prevent IGT patients with high CRP or CAIMT with anti-inflammatory therapy.

Objective To investigate the role of M2-type macrophages in interstitial fibrosis of kidney allograft.Methods The degree of interstitial fibrosis in renal biopsy tissues was assessed by Masson staining.By immunohistochemical double staining method and image analysis system,the levels of CD163 and SMA expression were detected in the renal biopsy tissues of 30 cases of CAI and 10 cases of normal kidney.The soluble CD163 was determined in urine by double antibody sandwich enzyme-linked immunosorbent assay.Results There were statistically significant differences in the expression of CD163 and SMA between kidney allograft and normal kidney tissue (P＜0.05).With the increase in renal fibrosis severity,the levels of serum Cr,BUN and the expression of CD163 and SMA were increased (P＜0.05).There was a positive correlation between the CD163 expression and the levels of serum Cr (r =0.937,P =0.000),and between the expression of CD63 and the level of sCD163 in urine.Conclusion The abnormal high expression of M2 macrophages in chronic renal allograft injury was associated with the degree of interstitial fibrosis and renal insufficiency in patients.

OBJECTIVETo investigate the expression of Versican in gastric carcinoma and its relationship with tumor angiogenesis.

METHODSProtein expression of Versican, vascular endothelial growth factor and CD34 was evaluated by immunohistochemistry (EliVision method) in 80 cases of gastric carcinoma and 30 samples of normal gastric tissue.

RESULTSThere were statistically significant differences in the expression of Versican, vascular endothelial growth factor and CD34 between gastric carcinoma and normal gastric tissue (P < 0.05). The expression of Versican was seen mainly in fibroblasts of the tumor and was correlated with tumor differentiation, clinical stage and lymph node metastasis (P < 0.05), whereas vascular endothelial growth factor was primarily seen in the cytoplasm of the tumor cells and correlated with tumor differentiation, clinical stage, Lauren classification and lymph node metastasis (P < 0.05). MVD was correlated with tumor differentiation, clinical stage, Lauren classification, depth of tumor invasion and lymph node metastasis (P < 0.05). In addition, positive correlation of Versican and VEGF protein expression was found in tumor cells (r = 0.467, P < 0.01).

CONCLUSIONThe expression of both Versican and vascular endothelial growth factor is closely associated with tumor angiogenesis in gastric carcinoma.

Species identification using DNA sequences is the basis for DNA taxonomy. In this study, we sequenced the ribosomal large-subunit RNA gene sequences (3,037-3,061 bp) in length of 13 Chinese Theileria stocks that were infective to cattle and sheep. The complete 28S rRNA gene is relatively difficult to amplify and its conserved region is not important for phylogenetic study. Therefore, we selected the D2-D3 region from the complete 28S rRNA sequences for phylogenetic analysis. Our analyses of 28S rRNA gene sequences showed that the 28S rRNA was useful as a phylogenetic marker for analyzing the relationships among Theileria spp. in ruminants. In addition, the D2-D3 region was a short segment that could be used instead of the whole 28S rRNA sequence during the phylogenetic analysis of Theileria, and it may be an ideal DNA barcode.
