The action mechanism of matrix metalloproteinases-2 (MMP-2) and tissue inhibitor of metalloproteinases-2 (TIMP-2) in the genesis, development and degeneration of haemangioma was investigated by detecting their expression in the tissue of haemangioma in different phases by using the immunohistochemistry. Fifty paraffin-embedded specimens of skin capillary haemangioma were collected, which were documented in the Department of Pathology, Renmin Hospital of Wuhan University from 2000 to 2006. All samples were stained by regular HE method, and proliferative cell nuclear antigen (PCNA) was tested by immunohistochemical S-P method. The samples were classified according to the Mulliken criteria and the expression pattern of PCNA. Immunohistochemical S-P method was applied to detect the expression of MMP-2 and TIMP-2 in proliferative and degenerative phases of cutaneous capillary haemangioma, and in normal skin tissues. In combination with the detection of the expression of factor VIII-related antigen, it was verified that in haemangioma tissues, the cells expressing MMP-2 and TIMP-2 were vascular endothelial cells. The MMP-2 and TIMP-2 expression was quantitatively analyzed by image analysis system (HPIAS-1000), and one-way ANOVA(107) and SNK(q) test were done to analyze average absorbance (A) and positive area rate of immunohistochemically positive particles by using SPSS11.5. The results showed: (1) Among 50 samples of haemangioma, there were 26 proliferative haemangiomas, and 24 degenerative haemangiomas, respectively; (2) The expression of MMP-2 was weak in normal vascular endothelial cells, cytoplasm of connective tissues and extracellular matrix around blood vessels. The expression of MMP-2 in proliferative group was significantly higher than in degenerative group and control group (normal skin) (P<0.05), but there was no statistically significant difference between the latter two groups; (3) TIMP-2 was highly expressed in normal tissues, degenerative vascular endothelial cells, cytoplasm of connective tissues and extracellular matrix around blood vessels. The expression level of TIMP-2 in proliferative phase was significantly lower than in degenerative phase (P<0.05), and the expression of TIMP-2 in proliferative phase was significantly different from that in degenerative phase and normal tissues (P<0.05). It was concluded that in proliferative phase of haemangioma, MMP-2 may promote over-proliferation of endothelial cells of haemangioma, and in degenerative phase, TIMP-2 can inhibit the proliferation of endothelial cells of haemangioma. The two substances play important roles in the genesis, development and degeneration of haemangiomas.

Objective:To study the effect of sulforaphane(SFN) on the growth of human bladder cancer cell and its mechanism in vitro. Method:Morphological characteristics of T24 cell nucleus induced by SFN were observed by AO/EB fluorescein staining .The effect of SFN on the T24 cell cycle was determined by flow cytometry. The expression of TrxR at the transcriptional and translational levels were measured by RT-PCR and Western blot methods respectively. Results:(1) After the cells were treated with 10 ?mol/L and 20 ?mol/L SFN for 24 h and 48 h, nuclear fragmentation and apoptotic body were seen under fluorescence microscope. (2) SFN could block the cell cycle at the G0/G1 phase showed by flow cytometry. Moreover, the treatment of 20 ?mol/L SFN for 48h could cause the appearance of sub-G1 before G0/G1 phase. (3) The expression of TrxR mRNA were increased by the treatment of 10 ?mol/L SFN for 4 h, 10 h,24 h ,compared with the control group. Furthermore ,the treatment with high dose SFN (20 ?mol/L ) for 10h or 24 h could induce the expression of TrxR mRNA more significantly . (4)The expression of TrxR protein in the 10 ?mol/L SFN for 24 h group was augmented compared with the control group , and aftertreatment with 20 ?mol/L SFN for 8 h and 24 h, its expression was significantly higher than that in the control group . Conclusion:SFN can inhibit the growth of T24 cell ,induce apoptosis and arrest T24 cell in G0/G1 phase. Its mechanism is associated with the induction of TrxR both at the transcriptional and translational levels.

Objective To investigate the expression and clinical significance of peroxisome proliferator activated receptor γ(PPARγ)in bladder urothelial cancer tissues.Methods Parafflin‐embeded specimen of bladder urothelial cancer tissues from 50 cases and normal tissues near the bladder urothelial cancer from 5 cases were harvested from the Pathology Department of the Renmin Hospital of Wuhan University between 2006 and 2009.Those cases had complete pathological and clinical data.The ex‐pression of PPARγ was detected by immunohistochemical SP method.Quantitative analysis of the PPARγ was measured by high definition pathological graphics context report system (HPIAS‐1000).One‐way analysis of variance and SNK (q)tests were used to analyze the mean density and the positive area rate of the immunohistochemical results.All data were processed by SPSS 13.0.Results The expression of PPARγwas significantly higher in bladder urothelial cancer tissues than in para‐carcinoma tis‐sues(P<0.05).Correlation between expression of PPARγ with TNM stag of bladder urothelial cancer was as follows :Positive rate of PPARγin the tissues with primary tumor size ≥3 cm was 72.4% ,significantly higher than 33.3% in the tissues with tumor size <3 cm(P<0.05);positive rate of PPARγin the cases with lymph node metastasis was 72.7% ,significantly higher than 46.4% in the cases without lymph node metastasis(P<0.05);positive rate of PPARγin patients at stage T3‐4 group was 75.0% ,significantly higher than 41.9% and 45.5% in patients at clinical stage T1 and T2(P<0.05);positive rate of PPARγin patients with poor differentiation was 68.2% ,significantly higher than 42.9% in patients with high or middle differentiation group(P<0.05).Conclusion PPARγ plays an important regulating role in the onset and progress of bladder urothelial cancer ;PPARγexpression level was correlated with primary tumor size ,pathological types and differentiation degree ,lymph node me‐tastasis and clinical stage.This result suggested that PPARγ was closely correlated to metastasis of bladder urothelial cancer.
