Objective To study the effect of mechanical tension on collagen arrangement and illustrate the relationship between tissue architecture and tension properties. Methods Cell morphologies, orientation and collagen arrangement of fibroblasts cultured in three different types of collagen gels with variation of mechanical tension were observed by phase contrast photomicrographs, light microscopy and transmission electron microscopy. Expression and distribution of a-smooth muscle actin (α-SMA) were investigated by immunohistochemistry. Results Phase contrast photomicrographs, light microscopy and transmission electron microscopy showed high level of tension distributed anisotropically in the monolayer gels and the anchored collagen gels, with bipolar shape of the fibroblasts, obvious polarity, arrangement of exogenous collagen fibres parallel to the long axis of the fibroblasts, especially prominent in monolayer gels. Low level of tension distributed isotropically was observed in floating collagen gels, with stellate morphology and arrangement of exogenous collagen fibres in a reticular array. Immunofluorescence showed that fibroblasts expressed high level of α-SMA protein distributed along the long axis of fibroblasts in the monolayer gels and the anchored collagen gels, especially in former ones. In contrast, few expression of α-SMA protein was found in floating collagen gels. Cell morphologies and orientation, expression and distribution of α-SMA as well as collagen arrangement of fibroblasts in the monolayer gels and the anchored collagen gels were similar to those in granulation tissue, whereas floating collagen gels resembled normal dermis or remodelled tissues. Conclusions Tissue architecture or morphology of the dermis are corresponding to tension proporties. Different tissue architectures are closely correlated with particular tension proporties.

Objective To observe the effects of Compound Uncaria Hypotensive Tablets on expressions of MCP-1 and MMP-9 of vascular remodeling in spontaneously hypertensive rats (SHR); To discuss it possible mechanism of action. Methods Totally 24 12-week old male SHR were randomly divided into SHR model group, Compound Uncaria Hypotensive Tablets group, and positive medicine group, with 8 rats in each group. Another 8 WKY rats were set as normal control group. Medication groups were given relevant medicine for gavage for successive 6 weeks. Noninvasive tail cuff method was used to observe blood pressure; morphological changes in thoracic aorta and renal artery were observed by HE staining; immunohistochemistry was used to detect the protein expressions of MCP-1 and MMP-9 in thoracic aortic wall. Results Protein expressions of MCP-1 and MMP-9 in thoracic aortic wall of SHR model group were significantly higher than those of normal control group (P<0.01); Compared with the SHR model group, protein expressions of MCP-1 and MMP-9 in thoracic aortic wall decreased significantly in the medication groups (P<0.05, P<0.01); Compared the Compound Uncaria Hypotensive Tablets group and positive medicine group, there was no obvious difference in protein expressions of MCP-1 and MMP-9 in thoracic aortic wall. Conclusion Compound Uncaria Hypotensive Tablets can reduce the blood pressure of SHR, reduce inflammation reaction, and regulate vascular remodeling, which mechanism may be related to down-regulation of expressions of MCP-1 and MMP-9 in SHR aortic endothelial cells.

Objective To investigate the influence of Cordyceps polysaceharide (Cp) on epithelial-to-mesenchymal transition (EMT) induced by transforming growth factor-β1 (TGF-β1)in proximal tubular epithelial cells (PTEC). Methods HK-2 cell proliferation was determined by MTT assay. After incubation of HK2 cells with increasing concentrations of TGF-β1 (0, 0.1, 0.5, 1, 5, 10 μg/L) at 48 h and with TGF-β1 (5 μ/L) at different time points, E-cadherin, α-SMA, FN expression at transcriptional and protein levels were detected by real-time PCR and Western blotting respectively. The cells were pretreated with 1,5, 10 g/L Cp respectively for 24 h before adding TGF-β1 (5μg/L), then the cells were incubated for additional 48 h, mRNA and proteinexpression of above 3 cytokines was examined by real-time PCR and Western blotting as well. Results CP alone (0.01, 0.1, 1,5, 10 g/L) induced HK-2 cell proliferation in a dose-dependent manner. TGF-β1 enhanced α-SMA, FN expression while inhibited E-cedherin expression at both transcriptional and" protein level in HK-2 cell. At transcriptional level, compared to single TGF-β1 (5 μg/L) stimulating group, after Cp (1,5, 10 g/L) pretreatment for 24 h, the inhibition rate of a-SMA mRNA was 37.98%, 68.08% and 84.36%, respectively; FN mRNA was 46.97%, 63.82% and 81.85%, respectively; E-cadherin was up-regulated by 0.67 fold, 2.69 folds and 5.43 folds, respectively (P<0.05). At protein level, the inhibition rate of α-SMA was 33.40%, 47.75% and 68.50%, respectively; FN was 16.26%, 65.92% and 80.30%, respectively; E-cadherin was up-regulated by 1.33 folds, 3.19 folds and 4.29 folds, respectively (all P<0.05). Under Light microscopy, the Cp reversed cell shape from spindle-shape induced by TGF-β1 to nearly normal shape. Conclusion Cp may exert its inhibitive effects on TGF-β1-induced EMT.
