Objective To investigate the expression and significance of transforming growth factor-?1(TFG-?1) and its correlation with the cellular proliferation activity in human gastric carcinoma (GC). Methods The expression of TGF-?1 and Ki-67 in 50 GC tissues and 10 normal gastric mucosal tissues was examined by immunohistochemistry. Results Compared with the normal gastric mucosal tissues, the expression of TGF-?1 and Ki-67 in GC was significantly higher. TGF-?1 expression was associated with histological differentiation,lymphatic metastasis and invasion depth of GC. And Ki-67 expression was related with lymphatic metastasis and invasion depth of GC too. Furthermore, a significant correlation between TGF-?1 and Ki-67 expressions in GC was found as well. Conclusion Gastric carcinomas with expression of TGF-?1 had high cellular proliferation activity. TGF-?1 could not inhibit cellular proliferation in GC. TGF-?1 stimulated GC cells invasion and metastasis. The overexpression of TGF-?1 and Ki-67 can serve as a reference marker to evaluate GC biological behavior.

Objective To investigate the expression of aquaporin 3 (AQP3) in lesions of four cuta-neous tumors. Methods Immtmohistochemistry was utilized to measure the expression of AQP3 in tissue samples from 30 patients with seborrheic keratosis, 15 patients with Bowen's disease, 32 patients with squa-mous cell carcinoma, 17 patients with malignant melanoma and 15 normal human controls. Results AQP3 was observed in all the tissue samples from both patients and controls. A significant increment was noticed in the expression of AQP3 in patients with Bowen's disease, squamous cell carcinoma and malignant melanoma compared with the normal controls (all P < 0.01), while no significant difference was found between patients with seborrheic keratosis and the controls (P > 0.05). The highest expression of AQP3 was obtained in lesions from patients with squamous cell carcinoma and malignant melanoma, followed by those with Bowen's disease (both P < 0.01), and there was no significant difference between squamous cell carcinoma and malignant melanoma (P > 0.05). The differentiation status of squamous cell carcinoma significantly corre-lated with the expression of AQP3 (P < 0.01). AQP3 was significantly higher in malignant melanoma with metastasis than that in malignant melanoma without metastasis (P < 0.05). Conclusion The expression of AQP3 is upregulated in malignant skin tumors.

[Summary] The aim of this study was to examine the association between obstructive sleep apnea-hypopnea syndrome ( OSAHS ) and microalbuminuria in type 2 diabetes mellitus patients. We found that severe OSAHS significantly increases the risk of early renal damage in type 2 diabetes mellitus patients with HbA1C<7% ( lowest oxygen saturation:OR=2. 41, 95% CI 1. 19-8. 08; apnea hyponea index: OR=2. 91, 95% CI 1. 50-9. 11), suggesting that OSAHS may increase the risk for early renal damage in type 2 diabetes mellitus, especially in those with successful control of glucose.

?ig-h_3 was first identified as a transforming growth factor-beta1-inducible gene in human lung adenocarcinoma cell line. It encodes for a secreted extracellular matrix (ECM) protein, which is thought to act on cell attachment and ECM composition. Previous study showed that ?ig-h_3 were highly expressed in human hepatoma cell lines and lowly expressed in human normal hepatic cells. The present study aimed to transfect ?ig-h_3 into 7721 cells to investigate its effect on secretion of MMPs in the transfected human hepatoma cells. Full-length ?ig-h_3 gene,cloned by reverse transcription polymerase chain reaction (RT-PCR) was inserted into the eukaryotic expression vector pEGFP-C_2. The recombinant plasmid was transfected into 7721 cells with Lipofectamine2000 and Gelatin-Zymography were adopted to detect the production of MMPs in the transfected cells. Results showed that ?ig-h_3/pEGFP-C_2 recombinant expression plasmid was successfully constructed and achieved high transfection efficiency. MMPs expression of the transfected cells was promoted significantly. These results suggest that overexpression of ?ig-h_3 promoted the production of MMPs, indicating that ?ig-h_3 may play roles in the invasive and metastatic processes of hepatoma.

Objective To evaluate the diagnostic values of MSCT for detecting atherosclerotic plaques on New Zealand rabbits models in comparison with pathologic results. Methods Fifteen New Zealand rabbits were enrolled in this study, including 5 with balloon injury and high-fat diet ( group A), 5 with high-fat diet only (group B) and 5 with regular feed (group C). 16th week late, contrast-enhanced MSCT scan was performed in all rabbits with 16 slice MSCT (16-MSCT) in group A and 64 slice MSCT (64-MSCT) in group B and C. The CT and pathological findings were compared in a double-blind manner. The sensitivities and specificities of 16-MSCT and 64-MSCT for detecting atherosclerotic plaques were evaluated by using Fisher test and x2 test. Results Sixty and seventy-five images on 16-MSCT and 64-MSCT had corresponding pathological slices. The sensitivities for the detection of plaques on 16-MSCT and 64-MSCT were 41.5% (22/53) and 64. 9% (24/37), and spocificities of 85. 7% (6/7) and 89. 5% (34/38), respectively. Conclusions 64-MSCT has a higher sensitivity in the detection of atherosclerotic plaques than 16-MSCT. Both scanners can be used to preclude the diagnosis of atherosclerosis.

Objective To study the relationship between coronary arteriographic and fluorescence fundus angiographic characteristics in type 2 diabetic patients with coronary heart disease.Methods The study was carried out by the analysis of the data from coronary arteriography and fluorescence fundus angiography in 203 type 2 diabetic patients with coronary heart disease in different groups divided according to age or total cholesterol level. Logisitic regression analysis was applied to explore various risk factors to angiographic characteristics.Results With advancing age,there were more involvement of 3 coronary vessels or the left main branch along with stageⅢretinopathy,but less single vessel diseases in the coronary arteries and less stageⅠretinopathy.The difference in coronary angiographic and fluorescence fundus angiographic characteristics between groups with different total cholesterol levels was not significant.Logistic regression analysis suggested that coronary artery diaease was related to age,sex and blood glucose and triglyceride levels while diabetic retinopathy was related to blood glucose level and age.Conclusion There is great difference in coronary arteriography and fluorescence fundus angiography among different age groups.Aging may aggravate the lesions both in the coronary arteries and fundal vessels in type 2 diabetic patients with coronary heart diseease.
