Expression of MMP-2 is associated with progression and lymph node metastasis of gastric carcinoma 总被引:40,自引:0,他引:40

AIMS: One important step in tumour invasion is the penetration of the basement membrane. Matrix metalloproteinases (MMPs) play a key role in the migration of normal and malignant cells through the basement membrane. The aim of this study was to investigate correlations between matrix metalloproteinase 2 (MMP-2) immunoreactivity and currently used classification systems and possible relationships between lymph node metastasis and MMP-2 expression. METHODS AND RESULTS: This prospective study analysed specimens obtained from 114 gastric cancer patients (mean age 64 years; range 33-86 years) who underwent gastrectomy with extended lymphadenectomy. All specimens were categorized according to UICC classification, WHO classification, tumour differentiation, Laurén classification, Ming classification and Goseki classification. Formalin-fixed paraffin-embedded tumour specimens were stained using an avidin-biotin complex peroxidase assay. MMP-2 expression in the tumour epithelium was studied by immunohistochemistry with semiquantitative (score 0-3) evaluation. The MMP-2 staining pattern was positive (score 1-3) in 93 (81.6%) specimens and negative (score 0) in 21 (18.4%) samples. No significant correlations were found between MMP-2 expression and other variables such as age, tumour differentiation, WHO, Lauren, Goseki, and Ming classifications. In contrast, the intensity of MMP-2 staining in tumour cells correlated significantly with depth of tumour infiltration (T-stage), lymph node metastasis (N-stage), distant metastasis (M-stage), and UICC stage. CONCLUSIONS: Expression of MMP-2 is strongly associated with tumour progression and lymph node metastasis in gastric cancer. Therefore MMP-2 staining may be clinically useful as predictor of tumour progression, especially for lymph node metastasis. 相似文献

Cytochrome P450 (CYP) enzyme 2J2, an epoxygenase predominantly expressed in the heart, metabolizes arachidonic acid to biologically active eicosanoids. One of the CYP2J2 products, 11,12-epoxyeicosatrienoic acid, has several vasoprotective effects. A frequent promoter polymorphism of CYP2J2 decreases gene expression and is associated with coronary artery disease. This association supports the vascular protective role of CYP-derived eicosanoids in cardiovascular disease. 相似文献

Bolus Administration of Saruplase in Europe (BASE), a Pilot Study in Patients with Acute Myocardial Infarction 总被引:2,自引:0,他引:2

To study the safety and efficacy of the thrombolytic agent saruplase as a bolus, the angiographic and clinical outcomes of three bolus regimens were investigated in a pilot study conducted in 192 patients with an acute myocardial infarction and were compared with the standard regimen. Fifty-two patients received a double bolus of 40 mg and 40 mg after 30 minutes, 51 patients a bolus of 80 mg, and 36 patients a bolus of 60 mg. Fifty-three patients received the standard regimen (a bolus of 20 mg and 60 mg IV infusion over 1 hour). At 60 minutes TIMI 2 and 3 flow were, respectively, 9.6% and 61.5% with the 40/40-mg bolus, 15.7% and 51.0% with the 80-mg bolus, 16.7% and 30.6% with the 60-mg bolus, and 7.5% and 54.7% with the standard 20/60-mg infusion. At 90 minutes TIMI 2 and 3 flow improved to 9.6% and 73.1%, 15.7% and 56.9%, 13.9% and 36.1%, and 5.7% and 71.7%, respectively. The primary endpoint, persistent patency (TIMI 2 + 3) at 24–45 hours, was seen in 69.2%, 64.7%, 44.4%, and 67.9% of patients who had no rescue PTCA, respectively. Inclusion in the 60-mg bolus group was prematurely stopped because of their low patency rates. The 40/40-mg bolus group had the highest mortality rate (13.5%), whereas the 60-mg bolus group had no deaths. Other adverse event rates were similar in the four groups. This clinical outcome is highly influenced by rescue PTCA of patients with insufficient TIMI flow. This pilot study indicates that in patients with an acute myocardial infarction, a double bolus of 40/40 mg resulted in the highest patency but also had the highest complication rate. The 80-mg single bolus is an attractive alternative for further evaluation because of its acceptable patency and event profile, and its easy form of administration. 相似文献

Lipophilic statins interfere with the inhibitory effects of clopidogrel on platelet function--a flow cytometry study. 总被引:25,自引:0,他引:25

AIMS: Clopidogrel is a pro-drug which is converted to an active, unstable drug by cytochrome P450 (CYP). The active drug irreversibly blocks one specific platelet adenosine 5'-diphosphate (ADP) receptor (P2Y12). It has been recently suggested that the most abundant human CYP isoform, 3A4, activates clopidogrel. Since certain lipophilic statins (i.e. simvastatin, atorvastatin, lovastatin) are a substrate of CYP3A4, we were interested in potential drug interactions between clopidogrel and statins. METHODS: In patients with coronary artery disease (n=47) in whom clopidogrel treatment was initiated for balloon angioplasty and stent implantation, blood samples were taken at 0, 5 and 48 h after oral administration of clopidogrel (loading dose 300 mg, followed by 75 mg daily). ADP-stimulated (1, 10, 100 micromol/l) expression of P-selectin (CD62P) on platelets was measured by flow cytometry, and used as a marker for the antiplatelet effect of clopidogrel. RESULTS: Pre-treatment with statins (atorvastatin, simvastatin) reduced significantly (10 micromol/l ADP stimulation) the inhibitory effects of clopidogrel during the loading phase (relative reduction after 5 h 29.3%) and, to a lesser extent during the maintenance phase (relative reduction after 48 h 16.6%). In addition we found a considerable individual heterogeneity in the response and three patients (6%) were identified in whom clopidogrel exerted almost no effect. CONCLUSION:Certain statins which are substrates of the CYP3A4 isoform competitively inhibit the metabolic activation of clopidogrel. As a result the relative clopidogrel induced platelet inhibition (P-selectin-expression) is diminished--but still there is a relative clopidogrel effect of more than 80% in the maintenance phase. It may be reasonable to test the therapeutic efficacy of clopidogrel in those patients who require long-term treatment. 相似文献
