| 2 | Plasma interleukin-18 reflects severity of ulcerative colitis显示文摘AIM: The aim of this study was to evaluate the association between ulcerative colitis activity and plasma or mucosal concentrations of interleukin (IL)-18.METHODS:Il-18 concentrations were measured in plasma and mucosal samples from 15 patients with active ulcerative colitis (UC).RESULTS: The mean plasma concentration of IL-18 measured in all patients (422±88 pg/mL) doubled the mean value in healthy controls (206±32 pg/mL); however,the difference was not statistically significant. Plasma IL-18 levels revealed a significant positive correlation with scored endoscopic degree of mucosal injury, disease activity index, clinical activity index and C-reactive protein concentration. The mean concentration of plasma IL-18 was significantly higher in patients with severe ulcerative colitis (535±115 pg/mL) than in patients with mild ulcerative colitis (195±41 pg/mL), and in healthy controls.Although the mucosal mean IL-18 concentration in severe ulcerative colitis (2 523±618 pg/mg protein) doubled values observed in mild one (1 347±308 pg/mg protein), there was no statistically significant difference.CONCLUSION: Plasma IL-18 can be considered as a surrogate marker helpful in evaluation of ulcerative colitis activity. | Alicja Wiercinska-Drapalo Flobert Flisiak Jerzy Jaroszewicz Danuta Prokopowicz | 2005 | World Journal of Gastroenterology2005,11,4: | 16 |

| 4 | Expression of matrix metalloproteinase-1 and tissue inhibitor of metalloproteinase-1 in ulcerative colitis显示文摘AIM: To examine the expression of metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the colonic mucosa of patients with ulcer- ative colitis (UC). METHODS: Reverse transcription-polymerase chain re- action (RT-PCR) and immunohistochemistry were used to study the expression of MMP-1 and TIMP-1 at both mRNA and protein levels in patients with UC and con- trols. The relationship between MMP-1 mRNA, TIMP-1 mRNA, MMP-1 mRNA/TIMP-1 mRNA ratio and the sever- ity of clinical symptoms of the patients with UC were also analyzed. RESULTS: The expression of MMP-1 mRNA and TIMP-1 mRNA in the ulcerated and inflamed colonic mucosa was signifi cantly higher than that in the non-inflamed colonic mucosa (P < 0.001), but there was no statistically signif i- cant difference in the non-inflamed colonic mucosa of UC patients and normal controls (P > 0.05). The mRNA ex- pression of MMP-1 and TIMP-1 in ulcerated colonic mu- cosa of UC patients was increased by 80-fold and 2.2-fold, respectively when compared with the normal controls. In the inflamed colonic mucosa, the increase was 30-fold and 1.6-fold, respectively. Immunohistochemical analy- sis showed that among the ulcerated, inflamed, and non-inflamed colonic mucosae of UC patients and the normal controls, the positive rate of MMP-1 expression was 87%, 87%, 40% and 35% respectively, and the positive rate of TIMP-1 expression was 89%, 89%, 80% and 75%, respectively. Furthermore, the expression of MMP-1 mRNA, TIMP-1 mRNA and the MMP-1 mRNA/ TIMP-1 mRNA ratio were correlated with the severity of clinical symptoms (P <0.05).CONCLUSION: Excessive expression of MMP-1 in the diseased colonic mucosa causes excessive hydrolysis of the extracellular matrix (ECM) and ulceration in UC pa-tients. MMP-1 mRNA, TIMP-1 mRNA and MMP-1 mRNA/ TIMP-1 mRNA ratio can be used as biomarkers to judge the severity of clinical symptoms in patients with UC. Exogenous TIMP-1 or MMP-1 inhibitor therapy is a novel treatment for patients with UC. | Ying-De Wang Pei-Yun Yan | 2006 | World Journal of Gastroenterology2006,12,37: | 13 |
| 5 | 组织金属蛋白酶及其抑制因子与肝纤维化显示文摘基质金属蛋白酶(matrix metalloproteinase,MMP)是体内重要的水解酶之一,几乎能降解细胞外基质(extracellular matrix,ECM)的所有成分;基质金属蛋白酶组织抑制因子(tissue inhibitor of metalloproteinasas,TIMPs)是MMPs的内源性抑制系统。近年来发现,MMPs/TIMPs调节失衡与肝纤维化的关系密切,可从多方面影响肝纤维化的形成。通过干扰MMPs与TIMPs基因的表达,研究肝纤维化的发病机制和药物治疗是有希望的途径。 | 孙华丽 张建军 | 2010 | 西南军医2010,12,1: | 12 |

| 12 | Impact of proteolytic enzymes in colorectal cancer development and progression显示文摘Tumor invasion and metastasis is a highly complicated, multi-step phenomenon. In the complex event of tumor progression, tumor cells interact with basement membrane and extracellular matrix components. Proteolytic enzymes(proteinases) are involved in the degradation of extracellular matrix, but also in cancer invasion and metastasis. The four categories of proteinases(cysteine-, serine-, aspartic-, and metalloproteinases) are named and classified according to the essential catalytic component in their active site. We and others have shown that proteolytic enzymes play a major role not only in colorectal cancer(CRC) invasion and metastasis, but also in malignant transformation of precancerous lesions into cancer. Tissue and serumplasma antigen concentrations of proteinases might be of great value in identifying patients with poor prognosis in CRC. Our results, in concordance with othersindicate the potential tumor marker impact of proteinases for the early diagnosis of CRC. In addition, proteinases may also serve as potential target molecules for therapeutic agents. | László Herszényi Loránd Barabás István Hritz Gábor István Zsolt Tulassay | 2014 | World Journal of Gastroenterology2014,20,37: | 3 |

| 20 | Matrix metalloproteinase-sensitive poly(ethylene glycol)/peptide hydrogels as an interactive platform conducive to cell proliferation during 3D cell culture显示文摘The response of extracellular matrix(ECM) to dynamic cell signals is of great significance for the regulation of cell behavior. In the present study, we prepared a type of matrix metalloproteinase(MMP)-sensitive degradable hydrogels(MSDHs) via the catalyst-free o-phthalaldehyde(OPA)/amine cross-linking reaction between o-phthalaldehyde-grafted four-arm poly(ethylene glycol)(4aPEG-OPA) and an MMP-sensitive degradable peptide. The gelation rates and storage moduli of MSDHs and the MMP-insensitive hydrogels(MIHs) based on an MMP-insensitive scramble peptide were comparable and dependent on the concentrations of precursor polymers. MSDHs were degradable while MIHs were stable in the presence of proteinase in vitro.The degradation of MSDHs was obviously faster than that of MIHs after subcutaneous injection into rats. In addition, both types of poly(ethylene glycol)/peptide hydrogels displayed excellent cytocompatibility in vitro, and showed good histocompatibility in vivo in the subcutaneous layer of rats. Furthermore, the proliferation of several MMP-expressing cell lines including MDA-MB-231 cells within MSDHs was obviously faster than that in MIHs, indicating the influence of metabolism-mediated scaffold degradation on the cell proliferation. This study provides a new biocompatible and biodegradable 3 D cell culture interactive platform for regulation of cell behavior. | RONG Yan ZHANG Zhen HE ChaoLiang CHEN XueSi | 2021 | Science China(Technological Sciences)2021,64,6: | 0 |
