Abstract
OBJECTIVE To investigate the relationship between serum matrix metalloproteinase-1(MMP-1) and matrix metalloproteinase-2(MMP-2) and the formation of deep venous thrombosis(LDVT) in lower extremity patients after surgery for lower extremity fracture, and to analyze the value of MMP-1 and MMP-2 in predicting the occurrence of LDVT after lower extremity fracture. METHODS From June 2018 to December 2021, 352 patients who planned to receive surgical treatment of lower limb fracture in our hospital were selected as the research objects. Venous blood was collected at 1, 2 and 3 days after surgery, respectively, and serum MMP-1 and MMP-2 levels were detected. The incidence of LDVT during hospitalization was analyzed, and the risk factors of postoperative LDVT in patients with lower limb fracture surgery and the predictive value of MMP-1 and MMP-2 for LDVT were analyzed. RESULTS LDVT occurred in 40 patients (LDVT group), the incidence of LDVT was 11.36%, and 312 patients did not occurred(no occurred group). The serum levels of MMP-1 and MMP-2 in LDVT group increased gradually after surgery; the serum levels of MMP-1 and MMP-2 in the no occurred group increased slightly after surgery at 2 days and then decreased at 3 days after surgery (P<0.01);the serum levels of MMP-1 and MMP-2 in LDVT group were higher than those in the no occurred group at 2 days and 3 days after surgery (P<0.05). Serum levels of MMP-1 and MMP-2 were positively correlated with serum levels of interleukin-6 (IL-6), IL-8 and tumor necrosis factor -α (TNF-α) in LDVT patients at 2 days and 3 days postoperatively (P<0.05). Operative time, MMP-1 and MMP-2 postoperative 3 days were related to the occurrence of LDVT after lower limb fracture (P<0.01). The area under the curve(AUC) predicted by MMP-1 and MMP-2 postoperative 3 days for LDVT after lower limb fracture was 0.738 and 0.744 respectively, and the AUC predicted by combined MMP-1 and MMP-2 was 0.910, which was higher than that predicted by single indicator(Z=2.819 and 2.025, P<0.05). CONCLUSION High levels of MMP-1 and MMP-2 after lower extremity fracture are closely related to the occurrence of LDVT, and 3 d mMP-1 and MMP-2 after surgery maybe used as evaluation indexes for LDVT risk prediction.

Abstract
BACKGROUND Systemic vascular injury occurs in coronavirus disease 2019 (COVID-19) patients; however, the underlying mechanisms remain unknown. METHODS To clarify the role of inflammatory factors in COVID-19 vascular injury, we used a multiplex immunoassay to profile 65 inflammatory cytokines/chemokines/growth factors in plasma samples from 24 hospitalized (severe/critical) COVID-19 patients, 14 mild/moderate cases, and 13 healthy controls (HCs). RESULTS COVID-19 patients had significantly higher plasma levels of 20 analytes than HCs. Surprisingly, only 1 cytokine, macrophage migration inhibitory factor (MIF), was among these altered analytes, while the rest were chemokines/growth factors. Additionally, only matrix metalloproteinase-1 (MMP-1) and vascular endothelial growth factor A (VEGF-A) were significantly elevated in hospitalized COVID-19 patients when compared to mild/moderate cases. We further studied MMP-1 enzymatic activity and multiple endothelial cell (EC) activation markers (soluble forms of CD146, intercellular adhesion molecule 1 [ICAM-1], and vascular cell adhesion molecule 1 [VCAM-1]) and found that they were highly dysregulated in COVID-19 patients. CONCLUSIONS COVID-19 patients have a unique inflammatory profile, and excessive MMP-1 and hyperactivation of ECs are associated with the severity of COVID-19.

Abstract
We tested a novel hypothesis that elevated levels of proteases in the maternal circulation of preeclamptic women activate neutrophils due to their pregnancy-specific expression of protease-activated receptor 1 (PAR-1). Plasma was collected longitudinally from normal pregnant and preeclamptic women and analyzed for MMP-1 and neutrophil elastase. Neutrophils were isolated for culture and confocal microscopy. Omental fat was collected for immunohistochemistry. Circulating proteases were significantly elevated in preeclampsia. Confocal microscopy revealed that tet methylcytosine dioxygenase 2 (TET2), a DNA de-methylase, and p65 subunit of NF-κB were strongly localized to the nucleus of untreated neutrophils of preeclamptic women, but in untreated neutrophils of normal pregnant women they were restricted to the cytosol. Treatment of normal pregnancy neutrophils with proteases activated PAR-1, leading to activation of RhoA kinase (ROCK), which triggered translocation of TET2 and p65 from the cytosol into the nucleus, mimicking the nuclear localization in neutrophils of preeclamptic women. IL-8, an NF-κB-regulated gene, increased in association with TET2 and p65 nuclear localization. Co-treatment with inhibitors of PAR-1 or ROCK prevented nuclear translocation and IL-8 did not increase. Treatment of preeclamptic pregnancy neutrophils with inhibitors emptied the nucleus of TET2 and p65, mimicking the cytosolic localization of normal pregnancy neutrophils. Expression of PAR-1 and TET2 were markedly increased in omental fat vessels and neutrophils of preeclamptic women. We conclude that elevated levels of circulating proteases in preeclamptic women activate neutrophils due to their pregnancy-specific expression of PAR-1 and speculate that TET2 DNA de-methylation plays a role in the inflammatory response.

Abstract
Anthracycline chemotherapy is commonly used to treat breast cancer yet may increase the level of matrix metalloproteinases (MMP) -2 and -9, which increase the risk of atherosclerosis. While exercise has been shown to reduce the level of MMP in patients with diabetes, high intensity interval training (HIIT) has not been utilized to improve level of MMP in women with breast cancer receiving anthracycline chemotherapy. Thirty women were randomized to either 8-week HIIT or control (CON) group. The CON group was offered the HIIT intervention after 8 weeks. MMP-1, -2 -7, -9, tissue inhibitor of MMP (TIMP) -1, and-2 were measured at baseline and post-intervention. Repeated measures ANCOVA and paired t-test were performed to assess changes in MMP and TIMP. Post-intervention, no significant between-group differences were observed for MMP and TIMP. However, within-group decrease in MMP-9 was observed in the HIIT group [104.3(51.9) to 65.2(69.1); P = 0.01]. MMP-9 in the CON group was not significantly changed [115.5(47.2) to 90.4(67.9);]. MMP-2 significantly increased in both the HIIT group [76.6(11.2) to 83.2(13.1); P = 0.007) and the CON group [69.0(8.9) to 77.6(11.1) P = 0.003). It is unclear whether an 8-week HIIT intervention influences MMP-9 in breast cancer patients undergoing anthracycline chemotherapy. Additional investigations are required to understand the exercise-induced changes in MMP-2 and -9 in women undergoing anthracycline chemotherapy.

Abstract
Serum markers that differentiate between tuberculous and non-tuberculous pneumonia would be clinically useful. However, few serum markers have been investigated for their association with either disease. In this study, serum levels of interferon gamma (IFN-γ), matrix metalloproteinases 1 and 9 (MMP-1 and MMP-9, respectively), and periostin were compared between 40 pulmonary tuberculosis (PTB) and 28 non-tuberculous pneumonia (non-PTB) patients. Diagnostic performance was assessed by analysis of receiver-operating characteristic (ROC) curves and classification trees. Serum IFN-γ and MMP-1 levels were significantly higher and serum MMP-9 levels significantly lower in PTB than in non-PTB patients (p < 0.001, p = 0.002, p < 0.001, respectively). No significant difference was observed in serum periostin levels between groups. ROC curve analysis could not determine the appropriate cut-off value with high sensitivity and specificity; therefore, a classification tree method was applied. This method identified patients with limited infiltration into three groups with statistical significance (p = 0.01), and those with MMP-1 levels < 0.01 ng/mL and periostin levels ≥ 118.8 ng/mL included only non-PTB patients (95% confidence interval 0.0–41.0). Patients with extensive infiltration were also divided into three groups with statistical significance (p < 0.001), and those with MMP-9 levels < 3.009 ng/mL included only PTB patients (95% confidence interval 76.8–100.0). In conclusion, the novel classification tree developed using MMP-1, MMP-9, and periostin data distinguished PTB from non-PTB patients. Further studies are needed to validate our cut-off values and the overall clinical usefulness of these markers.

Abstract
Background Matrix metalloproteinases (MMP´s) are known biomarkers of atherosclerosis. MMP´s are also involved in the pathophysiological processes underlying chronic obstructive pulmonary disease (COPD). Cigarette smoking plays an important role in both disease states and is also known to affect the concentration and activity of MMP´s systemically. Unfortunately, the epidemiological data concerning the value of MMP´s as biomarkers of COPD and atherosclerosis with special regards to smoking habits are limited. Methods 450 middle-aged subjects with records of smoking habits and tobacco consumption were examined with comprehensive spirometry, carotid ultrasound examination and biomarker analysis of MMP-1, -3, -7, -10 and -12. Due to missing data 33 subjects were excluded. Results The remaining 417 participants were divided into 4 different groups. Group I (n = 157, no plaque and no COPD), group II (n = 136, plaque but no COPD), group III (n = 43, COPD but no plaque) and group IV (n = 81, plaque and COPD). Serum levels of MMP-1,-7,-10-12 were significantly influenced by smoking, and MMP-1, -3, -7 and-12 were elevated in subjects with COPD and carotid plaque. This remained statistically significant for MMP-1 and-12 after adjusting for traditional risk factors. Conclusion COPD and concomitant plaque in the carotid artery were associated with elevated levels of MMP-1 and -MMP-12 even when adjusting for risk factors. Further studies are needed to elucidate if these two MMP´s could be useful as biomarkers in a clinical setting. Smoking was associated with increased serum levels of MMP´s (except for MMP-3) and should be taken into account when interpreting serum MMP results.

Abstract
BACKGROUND In an intervention study where 221 healthy elderly persons received selenium and coenzyme Q10 as a dietary supplement, and 222 received placebo for 4 years we observed improved cardiac function and reduced cardiovascular mortality. As fibrosis is central in the aging process, we investigated the effect of the intervention on biomarkers of fibrogenic activity in a subanalysis of this intervention study. MATERIAL AND METHODS In the present subanalysis 122 actively treated individuals and 101 controls, the effect of the treatment on eight biomarkers of fibrogenic activity were assessed. These biomarkers were: Cathepsin S, Endostatin, Galectin 3, Growth Differentiation Factor-15 (GDF-15), Matrix Metalloproteinases 1 and 9, Tissue Inhibitor of Metalloproteinases 1 (TIMP 1) and Suppression of Tumorigenicity 2 (ST-2). Blood concentrations of these biomarkers after 6 and 42 months were analyzed by the use of T-tests, repeated measures of variance, and factor analyses. RESULTS Compared with placebo, in those receiving supplementation with selenium and coenzyme Q10, all biomarkers except ST2 showed significant decreased concentrations in blood. The changes in concentrations, that is, effects sizes as given by partial eta2 caused by the intervention were considered small to medium. CONCLUSION The significantly decreased biomarker concentrations in those on active treatment with selenium and coenzyme Q10 compared with those on placebo after 36 months of intervention presumably reflect less fibrogenic activity as a result of the intervention. These observations might indicate that reduced fibrosis precedes the reported improvement in cardiac function, thereby explaining some of the positive clinical effects caused by the intervention. © 2017 BioFactors, 44(2):137-147, 2018.

Abstract
Phthalate exposure has been shown to be associated with adverse pregnancy outcomes. However, human studies informing relevant mechanistic pathways are lacking. Experimental studies have reported that matrix metalloproteinases (MMPs), which are responsible for extracellular protein degradation, may be upregulated in response to phthalate exposure. In this exploratory study we measured urinary phthalate metabolite concentrations, plasma MMP levels, and relevant covariates among 134 pregnant women. There were statistically significant or suggestive positive relationships between several phthalates, particularly between metabolites of di-(2-ethylhexyl) phthalate, with MMP-1 and MMP-9 levels. Further research is needed to confirm these results and how they may inform the mechanisms involved between phthalate exposure and adverse pregnancy outcomes.

Abstract
Here we present the study of enzymes involved in the regulation of extracellular matrix metabolism. It was the first study of this kind in the European part of the Arctic zone of the Russian Federation (AZRF). The contents of matrix metalloproteinases (MMP-1, -2, -3, -9) and tissue inhibitors of matrix metalloproteinases (TIMP-1, -2, -4) were measured in blood plasma of 91 men in AZRF (67o N) and 14 men in Western Siberia. The contents of MMP-1, MMP-9, TIMP-1 and TIMP-4 in plasma of northerners were higher compared to those of the residents of Western Siberia (55o N). Age-related dynamics of MMP and TIMP contents had a mixed trend in northerners. The maximum contents of MMP-1 and MMP-9 and of MMP-3 were observed in 30-39 and 40-49 years old groups, respectively. The contents of these enzymes tended to decease with age. The maximum contents of TIMP-1 and TIMP-2 and of TIMP-4 were in 50-59 and 60-69 years old groups, respectively, while the minimum contents of these enzymes were in the group of young men up to 29 years old. Hyaluronidase activity was minimal in 30-39 years old group and increased with age up to maximum values at 50-59 years old. Age-related imbalance of MMP/TIMP system (MSE content reduction with age vs TIMP content increase in older age groups) can be considered one of the reasons of the identified age-related increase of interstitial fibrosis and premature aging of the northerners.

Abstract
There is still a great need for detection of biomarkers for early prediction and diagnosis of cardiovascular complications (CVC) in patients with CHD. Objective: To determine the role of MMP-1, 8, 9 in the risk of CCO in patients with CHD before and after coronary artery bypass grafting (CABG). Methods. The study included 75 patients with coronary heart disease before and after myocardial revascularization by CABG, including 40 men and 35 women aged from 45 to 74 years. Patients were divided into two groups: I group - 25 patients with CVC registered after CABG (acute myocardial infarction, ischemic stroke, pulmonary thromboembolism Branch); II group - 50 patients with coronary heart disease without complications after myocardial revascularization. Blood sampling was performed the day before surgery, on the 1st, 3rd and 10th days after CABG. Determining the level of MMP-1, 8, 9 in the serum was performed by ELISA using reagents specific «RD Diagnostics Inc.», USA. Results are expressed in ng/ml. Data are presented as medians and quartiles of two (Me, Q25, Q75). Within and between-group differences were evaluated using the Mann - Whitney, Spearman correlation coefficient and c2 test within the application program SPSS №16. Statistically significant differences between the indicators considered when you reject the hypothesis and significance level of p<0,05. Results. A statistically increased concentration of MMP-1 and MMP-8 in patients in group I. Undetermined significant dynamics of MMP-9 in patients after myocardial revascularization. Conclusion. The results indicate that the level of MMP-1, 2.5 ng/ml or more in patients with CAD is a diagnostic criterion for the risk of TE complications. No association between high content of MMP-8 and the presence of complications in patients after surgery. There were no significant dynamics of MMP-9 in patients after myocardial revascularization.

Abstract
The article considers the measured values of the level of MMP-1, MMP-8 and MMP-9, and of their tissue inhibitor Type I (TIMP-1) in the blood serum and mixed saliva samples of 78 patients (31 women - 36.2 %, 47 men - 63.8 %) suffering from odontogenic phlegmons in the oral and maxillofacial region. The study indicators were assessed through the enzyme-linked immunosorbent assay using diagnostic sets RandD Diagnostics Inc. (USA). An uncontrolled hyperactivation of metal proteinases as one of the components of the systemic inflammatory response in case of phlegmon-related complications in the oral and maxillofacial region, as well as development of the sepsis syndrome were studied and it was determined that it results in distortion of the processes of reparative hystogeny and compel us to employ new approaches to the treatment of this type of patients (Tab. 2, Fig. 1, Ref. 13).

Abstract
BACKGROUND Osteoarthritis (OA) is one of the commonest forms of musculoskeletal disorders that leads to joint degeneration and has a major impact on patients' quality of life. Experimental and in vitro studies have suggested the protective roles of pomegranate juice (PJ) as a rich antioxidant source for mitigating cartilage inflammation. In this interventional study, 38 patients with knee OA were randomly divided into two groups: PJ or control for 6 weeks to evaluate the effect of this intervention on clinical signs, inflammation and antioxidant status. RESULTS Significant decreases in Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) total score (P = 0.01), stiffness score (P = 0.00) and physical function score (P = 0.01) were observed in PJ group after the intervention. The means of serum levels of matrix metalloproteinase (MMP)-13 was significantly decreased (P = 0.02) and glutathione peroxidase was increased in the intervention group compared with the control group after the study period (P = 0.02). CONCLUSIONS According to the findings of this clinical trial, PJ consumption can improve physical function and stiffness, decrease breakdown cartilage enzymes and increase antioxidant status in patients with knee OA. © 2016 Society of Chemical Industry.

Abstract
INTRODUCTION Accurate diagnosis of idiopathic pulmonary fibrosis (IPF) has important therapeutic and prognostic implications and would be greatly aided by reliable diagnostic biomarkers as IPF has sometimes overlapping features with other interstitial lung diseases (ILD). OBJECTIVES To explore the value of serum metalloproteinases (MMP) 1 and 7 levels in the differential diagnosis of IPF with other ILD. METHODS MMP-1/7 serum levels were measured using Luminex xMAP technology in 139 patients- 47 IPF, 36 non-IPF Usual Interstitial Pneumonia (UIP), 14 idiopathic Nonspecific Interstitial Pneumonia (iNSIP), 29 secondary NSIP (secNSIP), 13 stage IV sarcoidosis- and 20 healthy controls, and compared using the Mann-Whitney U test. RESULTS MMP-1 was significantly higher in IPF than non-IPF UIP (P = .042) and sarcoidosis (P = .027). MMP-7 was significantly higher in IPF than controls (P < .001), non-IPF UIP (P = .003), secNSIP (P < .001), and sarcoidosis (P < .001). The Area Under the Curve for IPF versus other ILD was 0.63 (95%CI, 0.53-0.73) for MMP-1, 0.73 (95%CI, 0.65-0.81) for MMP-7, and 0.74 (95%CI, 0.66-0.82) for MMP-1/MMP-7 combined. Sensitivity and specificity for MMP-7 cutoff = 3.91 ng/mL was 72.3% and 66.3%, respectively, Positive Predictive Values = 52.3% and Negative Predictive Values = 82.4%. CONCLUSIONS MMP-1 and particularly MMP-7 serum levels were significantly higher in IPF than in non-IPF UIP, the main entity in differential diagnosis. The value of these biomarkers as additional tools in a multidisciplinary approach to IPF diagnosis needs to be considered and further explored.

Abstract
BACKGROUND Head and neck squamous cell cancer (HNSCC) includes tumors of various anatomical sites sharing common etiological factors. Serum levels of MMP1, MMP2, and MMP9 were analyzed in patients with oropharyngeal, laryngeal, and hypopharyngeal carcinomas in an effort to elucidate the pathobiology and in order to find useful biomarkers of site-specific HNSCC. PATIENTS AND METHODS The study group comprised of 46 patients with HNSCC (21 with oropharyngeal, 21 with laryngeal and 4 with hypopharyngeal cancer). Serum levels of MMP1, -2, and -9 were determined by the MAGPIX multiplex method. P16 protein was detected by immunohistochemistry. Serum levels of matrix metalloproteinases (MMPs) were correlated with clinicopathological features of carcinomas and were compared with respect to tumor site. RESULTS Significant correlations were confirmed between p16 positivity and oropharyngeal cancer, MMP1 and p16 positivity, and recurrence and smoking. Statistically significant differences in serum levels of MMPs between cancer of different locations were not found. CONCLUSION MMP1 expression is significantly affected by smoking habit and by p16 and might mediate etiopathogenetical process in cancerogenesis of HNSCC. Our pilot study did not establish any utility of MMP1, -2, or -9 in clinical practice as diagnostic/prognostic markers.

Abstract
PURPOSE Matrix metalloproteinases (MMPs), in particular MMP1, 3, and 7, are believed to be critical to breast cancer invasion and metastasis and also may have important functions earlier in breast carcinogenesis. However, the relationship between circulating levels of MMP1, 3, and 7 and breast cancer risk is uncertain. METHODS We examined associations between plasma MMP1, 3, and 7 and breast cancer risk in a prospective case-control study nested within the Nurses' Health Study. Blood samples were collected from 801 cases who developed breast cancer between 1992 and 2000 and 801 matched controls, and MMP levels were measured via immunofluorescence assay. RESULTS No overall association was observed between any of these MMPs and breast cancer risk [top vs. bottom quintile; MMP1: odds ratio (OR) 0.9; 95 % confidence interval (CI) 0.7, 1.3; p-trend = 0.51; MMP3: OR 1.1; 95 % CI 0.8, 1.5; p-trend = 0.88; MMP7: OR = 1.2; 95 % CI 0.8, 1.7; p-trend = 0.18]. Further, findings did not significantly vary by time since blood draw, body mass index, or postmenopausal hormone use, or by breast cancer subtypes. CONCLUSIONS Circulating MMP1, 3, and 7 levels do not appear to be predictive of overall breast cancer risk.

Abstract
OBJECTIVE To observe the effect of detoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn on carotid intima-media thickness (IMT), plaque integral and plaque stability related serum indexes of patients with carotid atherosclerosis. METHOD Sixty and four cases of carotid artery atherosclerosis patients were assigned randomly to 2 groups: detoxifying and blood circulation activating treatment group (treatment group, 32 cases) and control group (32 cases). Patients in treatment group were treated with capsules of extraction of polygonum cuspidatum and hawthorn, 1 pill po, bid (dosage of administration: polygonum cuspidatum extraction 5.33 mg x kg(-1) x d(-1), hawthorn extraction 5.0 mg x kg(-1) x d(-1)); patients in control group were treated with lovastatin 20 mg po, qd (dosage of administration: 0.33 mg x kg(-1) x d(-1)). The course of treatment was six months. To observe changes of IMT, plaque integral, and detect the level of plaque stability related serum indexes such as Hs-CRP, MMP-1 and TIMP-1. RESULT After 6 months of treatment, in control group one patient quit the clinical trial because of liver dysfunction and one patient was rejected because of having not followed the therapeutic regimen. 32 cases in treatment group and 30 cases in control group were analyzed. The results showed that IMT and plaque integral of treatment group decreased significantly after the treatment (P < 0.05, P < 0.01), and there was no significant difference compared with control grope. Serum Hs-CRP, MMP-1 and MMP-1/TIMP-1 decreased after the treatment (P < 0.05, P < 0.01), and the treatment group was superior to control group in decreasing serum Hs-CRP (P < 0.05). CONCLUSION Detoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn has good effect of anti-atherosclerosis and promoting plaque stability. Its mechanism might be related with anti-inflammation and inhibiting degradation of extracellular matrix, and deserves further studies.

Abstract
AIM The aim of the study was to test the association between circulating levels of matrix prometalloproteinase1 (pro-MMP1) and its tissue inhibitors TIMP1 and TIMP2 with prevalent cardiovascular events. METHODS Prevalent cardiovascular events were documented in 500 participants of the Cyprus study (46% men) over the age of 40. Serum levels of pro-MMP1, TIMP1 and TIMP2 were measured with ELISA and the association between quartiles of serum levels and presence of cardiovascular disease (CVD) was tested using multivariable binary regression models. RESULTS Lower serum levels of pro-MMP1 and TIMP1 were strongly associated with presence of CVD at baseline even after adjustment for conventional risk factors (P(for trend)=0.006 and P=0.001, respectively) and inflammatory factors (P(for trend)=0.005 and P=0.002, respectively) with people in the highest quartile of pro-MMP1 having a reduced odds for cardiovascular disease by about 70% compared to the lowest quartile (OR(adjusted)=0.26; 95% CI=0.19 to 0.75; P=0.01), whereas people with TIMP1 levels >1000 ng/mL had a 75% reduced odds for CVD compared to the rest (OR(adjusted)=0.25; 95% CI=0.11 to 0.60; P(for trend)=0.002). TIMP2 levels were not associated with prevalent cardiovascular disease. CONCLUSION A strong association between lower levels of circulating pro-MMP1 and TIMP1 and risk of prevalent cardiovascular disease in a general population cohort over 40 years is evident, independent from common cardiovascular and inflammatory risk factors. The role of MMP1 and its tissue inhibitors, should be tested further in prospective studies of cardiovascular disease.

Abstract
INTRODUCTION Matrix metalloproteinases (MMPs) are believed to progressively degrade the collagenous components of the protective fibrous cap, leading to atherosclerotic plaque rupture or destabilization. Oxidized low-density lipoprotein (ox-LDL) enhances the release of CD147, known as the extracellular MMP inducer, from coronary smooth muscle cells. However, whether ox-LDL can induce platelet CD147 expression is unknown. Therefore, we investigated the influence of ox-LDL and high-density lipoprotein (HDL) on CD147 expression on human platelets. MATERIALS AND METHODS Washed platelets were incubated with ox-LDL (or native LDL) and HDL or anti-LOX-1 monoclonal antibody prior to incubation with ox-LDL. In parallel, buffer (PBS) was added to washed platelets as a control. The expression levels of CD147, CD62P, CD63 and Annexin V were assessed by flow cytometry, and soluble CD147 from the platelets was assessed by an enzyme-linked immunosorbent assay. Laser scanning microscopy (LSM) and transmission electron microscopy (TEM) were used to visualize the morphological changes and granule release, respectively, from the platelets. RESULTS Platelets treated with ox-LDL exhibited a significant increase in the expression of CD147 (or Annexin V), followed by increases in CD62P and CD63, compared with the control group. In contrast, HDL or anti-LOX-1 monoclonal antibody decreased these effects. The expression of soluble CD147 increased as the concentration of ox-LDL used to treat the platelets increased. After exposure to ox-LDL, morphological changes and granule release in the platelets were visualized by LSM and TEM. Additionally, the TEM revealed that HDL inhibits alpha-granule release. CONCLUSIONS In platelets, ox-LDL stimulates the release of CD147 via binding to LOX-1, whereas HDL inhibits this effect. This finding could provide new insights concerning the influence of ox-LDL and HDL on plaque stability by the up-regulation of CD147 on platelets.

Abstract
OBJECTIVE To investigate the antifibrotic effects of crocetin in scleroderma fibroblasts and in sclerotic mice. METHODS Skin fibroblasts that were isolated from three systemic scleroderma (SSc) patients and three healthy subjects were treated with crocetin (0.1, 1 or 10 μM). Cell proliferation was measured with an MTT assay. Alpha-smooth muscle actin was detected via an immunohistochemical method. Alpha 1 (I) procollagen (COL1A1), alpha 1 (III) procollagen (COL3A1), matrix metalloproteinase (MMP)-1 and tissue inhibitor of matrix metalloproteinase (TIMP)-1 mRNA levels were measured using real-time PCR. SSc mice were established by the subcutaneous injection of bleomycin. Crocetin (50 mg/kg/d) was injected intraperitoneally for 14 days. Dermal thickness and lung fibrosis were assessed with Masson's trichrome staining. Plasma ET-1 was detected with an enzyme-linked immunosorbent assay (ELISA). Skin and lung ET-1 and COL1A1 mRNA levels were measured via real-time PCR. RESULTS Crocetin inhibited the proliferation of SSc and normal fibroblasts, an effect that increased with crocetin concentration and incubation time. Crocetin decreased the expression of α-SMA and the levels of mRNA for COL1A1, COL3A1 and matrix metalloproteinase-1, while crocetin increased TIMP-1 mRNA levels in both SSc and normal fibroblasts. Skin and lung fibrosis was induced, and the levels of ET-1 in the plasma, skin and lungs were elevated in bleomycin-injected mice. Crocetin alleviated the thickening of the dermis and lung fibrosis; decreased COL1A1 mRNA levels in the skin and lung; and simultaneously decreased ET-1 concentrations in the plasma and ET-1 mRNA levels in the skin and lungs of the bleomycin-induced sclerotic mice, especially during the early phase (weeks 1-3). CONCLUSION Crocetin inhibits cell proliferation, differentiation and collagen production in SSc fibroblasts. Crocetin alleviates skin and lung fibrosis in a bleomycin-induced SSc mouse model, in part due to a reduction in ET-1.

Abstract
INTRODUCTION Arterial hypertension is often associated with a stiff aorta as a result of collagen accumulation in the aortic wall and may produce chest pain. In the present study, possible interrelationships between aortic function, collagen turnover and exercise-induced chest pain in patients with arterial hypertension and angiographically normal coronary arteries were investigated. METHODS Ninety-seven patients with arterial hypertension, angiographically normal coronary arteries and no evidence of myocardial ischemia on nuclear cardiac imaging during exercise test were studied. Of these, 43 developed chest pain during exercise (chest pain group) while 54 did not (no chest pain group). Carotid femoral pulse-wave velocity (PWVc-f) was used to assess the elastic properties of the aorta. Amino-terminal pro-peptides of pro-collagen type I, (PINP, reflecting collagen synthesis), serum telopeptides of collagen type I (CITP, reflecting collagen degradation), pro-metalloproteinase 1 (ProMMP-1), and tissue inhibitor of metalloproteinase 1 (TIMP-1, related to collagen turnover) were measured in plasma by immunoassay. RESULTS The chest pain group had higher PWVc-f, higher and /CITP ratio, and lower proMMP-1/ TIMP-1 ratio compared to the no chest pain group. PWVc-f (t=2.53, p=0.02) and PINP (t=2.42, p=0.02) were independently associated with the presence of chest pain in multiple regression analysis. CONCLUSIONS Patients with arterial hypertension, exercise-induced chest pain and angiographically normal coronary arteries, without evidence of exercise-induced myocardial ischemia, had a stiffer aorta compared to those without chest pain. Alterations in collagen type I turnover that favor collagen accumulation in the aortic wall may contribute to aortic stiffening and chest pain in these patients.

Abstract
INTRODUCTION Pregnancy causes changes in the hormonal balance, musculoskeletal, cardiovascular and lymphatic systems. The swelling of the lower limbs may also be one of the consequences of the enlarging uterus that increases body weight during pregnancy Determination of the serum concentrations of myeloperoxidase - MPO, extracellular matrix metalloproteinase - MMP, and intreleukine-6 - IL-6 allows for the assessment of inflammation. MPO belongs to the group of peroxidase enzymes with strong antibacterial and anti viral action. It is produced and released from the granules of neutrophils in inflammatory reactions, degenerative changes and neoplasmatic diseases. IL-6 is the main mediator of the inflammation in the live organism, released by monocytes and macrophages stimulated by interleukin-1. OBJECTIVE To assess the levels of inflammatory mediators: MMP MPO and IL-6 in women in the third trimester of pregnancy both healthy and those who experienced idiopathic edema of the lower limbs. MATERIAL AND METHODS We analyzed the changes in the concentration of biochemical parameters as: MMP-1, MPO and IL-6 in the serum of 20 healthy pregnant women between 36 and 40 weeks of gestation, and 8 pregnant women who developed idiopathic edema of the lower limbs. The R&D Systems Elisa tests were used to perform the measurement. The Quantikine Human IL-6 Immunoassay was used to measure the concentration of IL-6. The concentration was expressed in pg/ml. MMP-1 was measured using The Quantikine Human Pro -MMP-1. The value of MMP-1 concentration was expressed in ng/ml. MPO was measured using The Quantikine Human MPO Immunoassay and expressed in ng/ml. RESULTS The mean concentration of IL-6 was higher in the group of pregnant women with swelling of the lower limbs (group II) in comparison to healthy pregnant women (group I) and it was approximately 3,01 pg/ml, SD = 2,64, and 2,3 pg/ml, SD = 1,92, respectively. No statistical difference was found (p = 0,436). Parity has no influence on IL-6 concentration. The mean concentration of MPO in group I was 1797,04 ng/ml, SD = 1378,89, in II group it was 1702,54 ng/ml, SD = 1289,64. (p = 0,866). Parity has also no influence on MPO concentration. The mean concentration of MMP-1 in group I was 7,61 ng/ml, SD = 4,6, in group II it was 10,46 ng/ml, SD = 4,03. (p = 0,137). Significantly higher results were observed in primiparas with lower limbs swelling- 11,36 ng/ml when compared to multiparas - 9,57 ng/ml. CONCLUSIONS 1. There are no significant differences in the concentrations of the studied inflammatory mediators between the groups of healthy pregnant women and those with idiopathic edema observed in the lower limbs. The significance of these differences requires further confirmation. 2. There was a statistically significant difference between the concentrations of MPO in the group of primiparas with a multiparas with lymphatic edema.

Abstract
BACKGROUND AND OBJECTIVE Matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMP) have been implicated in chronic obstructive pulmonary disease (COPD) pathogenesis. However, the majority of studies have focused on single MMP, and there is limited information on parallel expression of MMP and their antagonists TIMP. We, therefore, investigated the serum profile of MMP 1-3, 7-9, 12 and 13, and TIMP 1-4 in COPD patients. METHODS Serum MMP 1-3, 7-9, 12 and 13, and TIMP 1-4 were measured in 74 COPD patients and 20 control subjects by multiple microsphere technology. RESULTS MMP 1-3 and MMP 7-9 were elevated in COPD patients compared with control subjects (P= 0.001-0.043). The increased concentrations of MMP 1, 8 and 9 paralleled GOLD stage (P= 0.002-0.007). TIMP 1 and 4 concentrations were elevated in COPD (P < 0.001). MMP 1, 8 and 9, and TIMP 1 and 4 serum levels in COPD non-smokers were higher than in control non-smokers (P = 0.002-0.025). MMP 12 and 13 levels were undetectable in our serum samples. CONCLUSIONS This study provides further evidence for increased MMP 1, 7-9, and TIMP 1 serum levels in COPD, and demonstrates for the first time serum elevation of MMP 2 and 3, and TIMP 4. The finding that circulating TIMP 4 levels are increased in COPD and the observed relationship between serum levels of MMP 1, 8 and 9, and GOLD stage requires verification in an expanded patient cohort.

Abstract
BACKGROUND Cardiac extracellular matrix (ECM) is a dynamic and metabolically active collagenous network that responds to mechanical strain. The association between ECM turnover and right ventricular failure (RVF) development after left ventricular assist device (LVAD) implantation in patients with advanced heart failure (HF) was investigated. METHODS Circulating levels of osteopontin, metalloproteinases (MMP)-2 and MPP-9, and tissue inhibitor of MMP (TIMP)-1 and TIMP-4 were measured in 61 patients at LVAD implantation and explantation and in 10 control subjects. RVF was defined as the need for RVAD, nitric oxide inhalation > 48 hours and/or inotropic support > 14 days. RESULTS All ECM markers were elevated in patients with HF compared with controls (all p < 0.05). RVF developed in 23 patients (37.7%) on LVAD support. All ECM markers decreased on LVAD support in patients without RVF (all p < 0.05), but serum MMP-2, TIMP-1, TIMP-4, and osteopontin remained elevated in RVF patients. Multivariate analysis identified that right ventricular stroke work index (RVSWI), circulating B-type natriuretic peptide, and osteopontin were associated with RVF (all p < 0.05). Osteopontin correlated inversely with RVSWI (r = -0.44, p < 0.001). Osteopontin levels > 260 ng/ml discriminate patients who develop RVF from those without RVF (sensitivity, 83%; specificity, 82%). CONCLUSIONS Marked elevation of osteopontin levels before LVAD placement is associated with RVF development. Persistent elevation of circulating ECM markers after LVAD implantation characterizes patients who develop RVF. These novel biomarkers would have a potential role in the prediction of RVF development in patients undergoing LVAD implantation.

Abstract
UNLABELLED Chronic obstructive pulmonary disease (COPD) is characterized by the progressive destruction of the extracellular matrix of the lung. Matrix metalloproteinases (MMPs) and their inhibitors, especially tissue inhibitor of matrix metalloproteinase-1 (TIMP-1), play a central role in the lung remodeling in COPD. Their concentrations in the sputum and bronchoalveolar lavage are considered as a sign of the local inflammation in COPD patients. The aim of the study was to evaluate of the MMP-9 and TIMP-1 serum concentration in COPD patients with respect to the correlation with a systemic inflammatory process. MATERIAL AND METHODS Thirty six COPD patients (29 male and 7 female) were enrolled into the study. Age-matched, healthy 15 subjects (11 male and 4 female) were selected as a control group. Serum levels of MMP-9, TIMP-1 and CRP were measured. The pre- and post-bronchodilator forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio were determined. The Spearman correlation was performed. RESULTS The serum MMP-9 concentration was significantly higher in the COPD patients than that in the control group (COPD: 194.8 +/- 129.1 ng x ml(-1); control subjects: 11.7 +/- 2.1 ng x ml(-1); p < 0.001). The serum concentration of CRP was significantly higher in the COPD patients than that in the control group (COPD: 14.3 +/- 6.3 ng x ml(-1); control subjects: 6.2 +/- 2.8 ng x ml(-1); p < 0.001). There was statistically significant correlation between the MMP-9 concentration and the CRP level in the serum of patients with COPD (p < 0.01; r = 0.45). There were no significant differences in the serum TIMP-1 concentrations between the control group and COPD patients. There was statistically significant, negative correlation between the FEV1 % of predicted value and the MMP-9 concentration (p = 0.03; r = -0.43). CONCLUSIONS MMP-9 may play an important role in the systemic inflammatory process in COPD. The serum concentrations of MMP-9 correlate with the stage of COPD.

Abstract
OBJECTIVE To study the therapeutic efficacy of Qianggan Capsule (QC) in treating patients Seventy pa-with chronic hepatitis B fibrosis from the pathological aspect and serum fibrosis markers. METHODS patients with chronic hepatitis B were randomly assigned to two groups, the treated group (45 cases) and the control group (25 cases). QC was given to patients in the treated group, while glucurone and compound vitamin B were given to those in the control group. The therapeutic course for both groups was 6 months. The therapeutic effect was assessed by determination of fibrosis markers including serum levels of platelet-derived growth factor-BB (PDGF-BB), transforming growth factor beta 1 (TGF-beta1), matrix metalloproteinases-1 (MMP-1), tissue inhibitors of metalloproteinases-1 (TIMP-1) and serum levels of alanine transaminase (ALT), total bilirubin (TBIL), albumin (ALB), and prothrombin time (PT) were completed 1 month before treatment and at the end of the trial respectively. RESULTS (1) Serum levels of ALT, TBIL, PT decreased obviously and the serum ALB level obviously increased in both groups (all P<0.05), showing no significant difference between the two groups (P>0.05). (2) Hepatic fibrosis markers: Serum levels of PDGF-BB, TGF-1P3, and TIMP-1 significantly decreased, and serum MMP-1 level markedly increased in the treated group more than before treatment (all P<0.05). No significant difference was shown between before and after treatment in each index of the control group (P>0.05). Serum levels of PDGF-BB, TGF-beta1, and TIMP-1 were obviously lower and the serum MMP-1 level was obviously higher in the treated group than in the control group after treatment (all P<0.05). (3) Hepatic histopathological results: The hepatic inflammatory necrosis activity and the hepatic fibrosis degree in the treated group were significantly improved (P<0.05), with the total effective rate of the hepatic necrosis activity improvement being 40.00% and that of the hepatic fibrosis degree being 57.78%. But there was no obvious improvement in the hepatic inflammatory necrosis activity or the hepatic fibrosis degree in the control group (P>0.05). CONCLUSIONS QC could effectively improve serological indices and pathological indices of chronic hepatitis B fibrosis patients, showing better therapeutic effect in reversing hepatic fibrosis and alleviating hepatic inflammatory necrosis.

Abstract
Accurate monitoring of liver fibrosis changes in patients with hepatitis C virus (HCV) infection would be helpful in defining the need to intervene, implement the appropriate response in treatment and to minimize the use of liver biopsy. We aimed to evaluate the diagnostic utility of the different serum markers and indices in detecting liver fibrosis in study patients. Initial liver biopsy, routine liver function tests, estimation of hyaluronic acid, MMP-1, and PIIINP levels was performed for 30 Egyptian patients with HCV and 15 controls. Marker algorithms based on common laboratory such APRI score, Fibrotest and Actitest. PIIINP and MMP-1 serum markers were combined and entered into a stepwise logistic regression analysis with formulation of a score equation for fibrosis staging. Combined PIIINP and MMP-1 yielded different cut off scores to estimate two clinically relevant fibrosis stages: "significant fibrosis" versus "extensive fibrosis. Apri score also showed AUC of 1.0 with 100 % sensitivity and specificity to exclude the presence of cirrhosis and was significantly correlated to Metavair fibrosis stage in early fibrosis. On the other hand, PIIINP, Fibrotest and acti test were significantly correlated to Metavair fibrosis stage in both early and late fibrosis. In conclusion, integrating PIIINP/MMP-1 score was able to provide reliable information about the degree of liver fibrosis in chronic hepatitis C patients using different cut-offs values. A combination of liver markers as well as its related indices is an emerging tool to differentiate early from advanced liver fibrosis in HCV patients.

Abstract
Our objective in the present study was to observe the change in the serum MMP-1 concentration using ELISA in 129 chronic hepatitis C (CHC) (78 non-cirrhotic and 51 with cirrhotic liver) and 50 healthy controls. The values of MMP-1 concentration increased in patients with CHC according to the stage of liver fibrosis. An area under the ROC curves (AUC) of the MMP-1 was 0.98 for discriminating patients with cirrhotic liver from healthy individuals and was 0.78 for discriminating patients with cirrhotic liver from non cirrhotic patients. The diagnostic potential of MMP-1 for discriminating cirrhosis from healthy individuals was very high with 98% sensitivity and 97% efficiency. MMP-1 detected cirrhosis in CHC with 71% sensitivity and 73% efficiency. In Conclusion, measurement of serum MMP-1 is useful for diagnosing liver cirrhosis in CHC patients.

Abstract
Background Atrial fibrosis creates a vulnerable tissue for atrial fibrillation (AF), but the spatial disarray of collagen fibers underlying atrial fibrosis is not fully elucidated. Objective This study hypothesizes that harmonics optical microscopy can illuminate the spatial mal-alignment of collagen fibers in AF via a layer-by-layer approach. Patients and Methods Atrial tissues taken from patients who underwent open-heart surgery were examined by harmonics optical microscopy. Using the two-dimensional Fourier transformation method, a spectral-energy description of image texture was constituted and its entropy was used to quantify the mal-alignment of collagen fibers. The amount of collagen fiber was derived from its area ratio to total atrial tissue in each image. Serum C-terminal pro-collagen pro-peptide (CICP), pro-matrix metalloproteinase-1 (pro-MMP-1), and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) were also evaluated. Results 46 patients were evaluated, including 20 with normal sinus rhythm and 26 with AF. The entropy of spectral-energy distribution of collagen alignment was significantly higher in AF than that in sinus rhythm (3.97±0.33 vs. 2.80±0.18, p<0.005). This difference was more significant in the permanent AF group. The amount of collagen was also significantly higher in AF patients (0.39±0.13 vs. 0.18±0.06, p<0.005) but serum markers of cardiac fibrosis were not significantly different between the two groups. Conclusions Harmonics optical microscopy can quantify the spatial mal-alignment of collagen fibers in AF. The entropy of spectral-energy distribution of collagen alignment is a potential tool for research in atrial remodeling.

Abstract
Circulating levels of inflammatory markers predict the risk of cardiovascular disease (CVD), mediated perhaps in part by dietary fat intake, through mechanisms only partially understood. To evaluate post-fat load changes in inflammatory markers and genetic influences on these changes, we administered a standardized high-fat meal to 838 related Amish subjects as part of the Heredity and Phenotype Intervention (HAPI) Heart Study and measured a panel of inflammatory markers, including C-reactive protein (CRP), interleukin-1beta (IL-1beta), matrix metalloproteinase-1 and -9 (MMP-1 and MMP-9), and white blood cell (WBC) count, before and 4 h after fat challenge (CRP prechallenge only). Heritabilities (h(2) +/- s.d.) of basal inflammatory levels ranged from 16 +/- 8% for MMP-9 (P = 0.02) to 90 +/- 7% for MMP-1 (P < 0.0001). Post-fat load, circulating levels of WBC, MMP-1, and MMP-9 increased by 16, 32, and 43% (all P < 0.0001), with no significant changes in IL-1beta. Postprandial changes over the 4-h period were modestly heritable for WBC (age- and sex-adjusted h(2) = 14 +/- 9%, P = 0.04), but the larger MMP-1 and MMP-9 changes appeared to be independent of additive genetic effects. These results reveal that a high-fat meal induces a considerable inflammatory response. Genetic factors appear to play a significant role influencing basal inflammatory levels but to have minimal influence on post-fat intake inflammatory changes.

Abstract
OBJECTIVE To detect the levels of matrix metalloprotease (MMP)-1 and MMP-7 in the serum and the bronchoalveolar lavage fluid (BALF) of patients with idiopathic pulmonary fibrosis (IPF) and sarcoidosis (Stage II), and therefore to investigate the significance of these changes in the pathogenesis of IPF. METHODS Forty-four clinically confirmed cases of IPF were recruited, with the patients' age ranging from 46 to 70 years (58 ± 9 years). Twenty patients with sarcoidosis, aged 35 to 65 (50 ± 12) years, were also studied. Enzyme-linked immunoabsorbent assay was used to detect the levels of MMP-1 and MMP-7 in the serum and the BALF samples. RESULTS In the serum of patients with IPF, the level of MMP-1 [3.78 (0.14 - 13.44) µg/L] was lower than that in patients with sarcoidosis [7.79 (4.67 - 10.68) µg/L (z = -3.53, P < 0.01)], but the level of MMP-7 [7.83 (3.57 - 14.37) µg/L] was higher than that in patients with sarcoidosis [4.04 (0.06 - 9.94) µg/L (z = -3.84, P < 0.01)]. In the BALF of patients with IPF, the level of MMP-1 [1.09 (0.04 - 5.14) µg/L] was lower than that in patients with sarcoidosis [2.08 (0.05 - 4.16) µg/L (z = -1.53, P > 0.05)], but the level of MMP-7 [3.75 (1.10 - 9.87)µg/L] was higher than that in patients with sarcoidosis [1.16 (0.02 - 4.47) µg/L (z = -5.33, P < 0.01)]. The serum level of MMP-7 in patients with IPF was negatively correlated with the diffusing capacity of carbon monoxide(r = -0.56, P < 0.01) and the percentage of neutrophils (r = -0.47, P < 0.01). The level of MMP-7 in the BALF showed a negative correlation with diffusing capacity of carbon monoxide (r = -0.31, P < 0.05). CONCLUSIONS The results suggest that MMP-1 may be increased in the inflammatory phase as compared to the matrix remodeling phase of lung fibrosis, while MMP-7 may be increased in the matrix remodeling phase rather than in the inflammatory phase. MMP-7 may act as an important indicator for the severity of IPF.

Abstract
Cardiovascular disease is the leading cause of morbidity and mortality among captive chimpanzees. The most prevalent form of cardiovascular disease among chimpanzees is sudden cardiac death. Myocardial fibrosis was the only significant pathologic lesion observed in affected animals at necropsy. We previously showed an association between myocardial fibrosis and sudden cardiac death. The presumed pathogenesis was interstitial myocardial fibrosis that led to decreased myocardial contractility and interrupted signal propagation in the heart, leading to fibrillation and resulting in sudden cardiac death. In this pilot study, we assayed 5 biomarkers of collagen types I and III metabolism and fibrogenesis and studied their association with CVD in chimpanzees. The biomarker MMP1 did not crossreact in chimpanzee sera and could not be studied further. Two biomarkers (TIMP1 and PINP) and their difference showed no significant association with CVD in chimpanzees. The biomarkers ICTP and PIIINP were significantly increased in cases of CVD with concurrent renal disease. Furthermore, both biomarkers showed a significant trend to increase with disease severity. We conclude that ICTP and PIIINP warrant further study for antemortem detection of renal and myocardial fibrosis in chimpanzees.

Abstract
Aim of the study--investigation of dynamics of levels of serum markers of myocardial fibrosis matrix metalloproteinase-1 (MMP-1), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1)--at the background of 3 months hypotensive therapy in 39 patients with arterial hypertension and paroxysmal form of atrial fibrillation. Twenty patients received sotalol, 19--retard form of verapamil. After 3 months of hypotensive therapy in all patients and separately in groups of patients receiving sotalol and verapamil no significant changes of MMP-1 and TIMP-1 occurred. However in patients with most pronounced hypotensive effect according to 24-hour blood pressure monitoring significant elevation of MMP-1 and lowering of TIMP-1 levels took place. This was associated with improvement of ventricular diastolic function. In most patients longer period of therapy (more than 3 months) is required for achievement of regression of damage to the heart.

Abstract
Matrix metalloproteinases are proteolytic enzymes which degrade extracellular matrix proteins. Along with their specific inhibitors--issue inhibitors of metalloproteinases--they play an important role in the spreading of malignant tumours. The research conducted in recent years has shown that metalloproteinases and their inhibitors contribute substantially to the ovarian cancer progression, participating both in in situ tumours growth, and the spreading of neoplasm via peritoneal fluid. The assessment of serum concentration of some metalloproteinases and their inhibitors appeared to be useful in differential diagnosis between malignant, borderline and benign ovarian tumours. In numerous research, it was revealed that the expression of metalloproteinases in primary tumours and in metastatic changes has a prognostic value. Moreover, the pre-operational assessment of concentration of TIMP-1 in blood serum allows to select the cases of an ovarian cancer with an aggressive phenotype and unfavourable prognosis. Despite great expectations, the usage of synthetic inhibitors of metalloproteinases did not bring significant changes and improvement to ovarian cancer treatment.

Abstract
AIM To evaluate the effect of ACE inhibitor enalapril, AR blocker candesartan and their combination on left ventricular hypertrophy (LVH) and content of biochemical markers of collagen balance in patients with hypertensive LV hypertrophy. MATERIAL AND METHODS. A total of 66 patients with arterial hypertension with LV hypertrophy were divided into two groups. Group 1 (n = 33) received candesartan (8-16 mg/day), group 2 (n = 33) received enalapril (10-20 mg/day). In effective hypotensive response to the initial treatment, it was continued for 6 months. If in two months of monotherapy the effect was unsatisfactory, the other drug was added. At baseline and upon 6 months of treatment all the patients were examined for myocardial mass index (MMI), matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of matrix metalloproteinase-1 (THMP-1) in the blood. RESULTS In effective initial treatment with candesartan 6-month treatment lowered LV MMI by 13.9%, while in enalapril group--only by 1.5%. In addition of the second drug in ineffective initial therapy the reduction was 5.1%. THMP-1 did not change during the trial. CONCLUSION In patients with hypertensive LVH candesartan more effectively treated LVH. The addition of the second RAS blocker in insufficient efficacy of the initial one significantly reduces LV MMI. A significant antifibrotic effect was achieved only in case of simultaneous use of two RAS blockers.

Abstract
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a chronic progressive fibrotic lung disease associated with substantial morbidity and mortality. The objective of this study was to determine whether there is a peripheral blood protein signature in IPF and whether components of this signature may serve as biomarkers for disease presence and progression. METHODS AND FINDINGS We analyzed the concentrations of 49 proteins in the plasma of 74 patients with IPF and in the plasma of 53 control individuals. We identified a combinatorial signature of five proteins-MMP7, MMP1, MMP8, IGFBP1, and TNFRSF1A-that was sufficient to distinguish patients from controls with a sensitivity of 98.6% (95% confidence interval [CI] 92.7%-100%) and specificity of 98.1% (95% CI 89.9%-100%). Increases in MMP1 and MMP7 were also observed in lung tissue and bronchoalveolar lavage fluid obtained from IPF patients. MMP7 and MMP1 plasma concentrations were not increased in patients with chronic obstructive pulmonary disease or sarcoidosis and distinguished IPF compared to subacute/chronic hypersensitivity pneumonitis, a disease that may mimic IPF, with a sensitivity of 96.3% (95% CI 81.0%-100%) and specificity of 87.2% (95% CI 72.6%-95.7%). We verified our results in an independent validation cohort composed of patients with IPF, familial pulmonary fibrosis, subclinical interstitial lung disease (ILD), as well as with control individuals. MMP7 and MMP1 concentrations were significantly higher in IPF patients compared to controls in this cohort. Furthermore, MMP7 concentrations were elevated in patients with subclinical ILD and negatively correlated with percent predicted forced vital capacity (FVC%) and percent predicted carbon monoxide diffusing capacity (DLCO%). CONCLUSIONS Our experiments provide the first evidence for a peripheral blood protein signature in IPF to our knowledge. The two main components of this signature, MMP7 and MMP1, are overexpressed in the lung microenvironment and distinguish IPF from other chronic lung diseases. Additionally, increased MMP7 concentration may be indicative of asymptomatic ILD and reflect disease progression.

Abstract
INTRODUCTION Non-ST elevation acute coronary syndrome (ACS) represents a spectrum of risk, with electrocardiographic (ECG) changes and a positive troponin being associated with higher morbidity and mortality. Ischaemia produces alterations in the collagenous component of the heart, even in the absence of myocyte necrosis. Collagen turnover can be assessed biochemically with C-propeptide for type I collagen (PICP) and C-telopeptide for type I collagen (CITP) being markers of collagen synthesis and degradation respectively. Tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) is a marker of inhibition of degradation. METHODS Fifty-two patients with non-ST elevation acute ACS were recruited and dichotomised into high- and low-risk groups based on ECG and troponin level. Sequential measurements of plasma PICP, CITP and TIMP-1 were performed over a 48 hour period. RESULTS Twenty were classified as low-risk (negative troponin and normal ECG) and 32 as high-risk. PICP was within the normal range at all time points in both groups. However, admission CITP was higher in the high-risk group (3.7 vs. 2.6 ng/ml, p<0.001) and, unlike the low-risk group, demonstrated a further rise over 48 h. Similarly, mean TIMP-1 displayed a sequential change over time in the high-risk group only, and admission level was higher compared to the low-risk group (302 vs. 221 ng/ml, p<0.01). DISCUSSION There is serological evidence of time-dependent altered collagen metabolism in high-risk ACS, which is not present in the low-risk group. This may reflect a degree of remodeling and may aid risk stratification of patients presenting with non-ST elevation ACS.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) are elevated in the brain tissue of patients with dementia and may play a role in the pathophysiology of dementia. MMP-9 and tissue inhibitors of MMPs (TIMPs) are elevated in postmortem brain tissue of patients with Alzheimer's disease (AD). In a previous study we showed that circulating levels of MMP-9 are elevated in AD patients. The aim of the present study was to examine circulating levels of MMP-1, MMP-2, MMP-9, TIMP-1 and TIMP-2 in the plasma of patients with mild cognitive impairment (MCI), AD, vascular dementia (VaD), dementia with Lewy bodies (DLB) and frontotemporal dementia (FTD), to determine, whether plasma profiles of MMPs and TIMPs differ in various types of dementia. METHODS Gelatinolytic activity (MMP-2 and MMP-9) was measured in all plasma samples by zymography. Levels of MMP-2, MMP-9, MMP-1 as well as TIMP-1 and TIMP-2 were measured by ELISA. RESULTS We found constitutive expression of MMP-1, -2 and -9 as well as TIMP-1 and -2 in all the samples investigated. As shown previously, MMP-9 was significantly elevated in the plasma of AD patients (p = 0.004) as compared to controls and MCI patients. Plasma levels of TIMP-1 were significantly lower in VD samples as compared to all other groups. Levels of TIMP-2 were significantly lower in patients with FTD as compared to AD, VaD and MCI patients. There were no significant changes of MMP-1 and MMP-2 levels in the samples. CONCLUSION These findings suggest that circulating levels of MMP-9, TIMP-1 and TIMP-2 and changes in the MMP/TIMP balance in plasma differ in various types of dementia.

Abstract
Matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) are thought to be associated with coronary artery disease. The association of these markers with incident coronary artery disease has not been well described. Using a case-cohort design, we selected 216 individuals who had incident coronary artery disease (case group) and 225 individuals from a cohort random sample (comparison group) from participants enrolled in the Atherosclerosis Risk in Communities study. We measured plasma levels of MMP-1 and TIMP-1, traditional risk factors, and other markers of inflammation. We found no significant difference in TIMP-1 levels between the case group (827.8 +/- 23.8 ng/mL) and the comparison group (819.31 +/- 16.1 ng/mL) (P=0.77), and no significant difference in the frequency of MMP-1 levels that were dichotomized at the minimum detectable value of 1.7 ng/mL (P=0.49). In models adjusted for age, sex, race, body mass index, hypertension, diabetes, total cholesterol, high-density lipoprotein cholesterol, triglycerides, fibrinogen, von Willebrand factor, and white blood cell count, the hazard-rate ratio for incident coronary artery disease was 1.14 (95% confidence interval, 0.63-2.04; P=0.67) for individuals whose TIMP-1 levels were above, versus at or below the mean, and 1.17 (95% confidence interval, 0.63-2.19; P=0.62) for individuals whose MMP-1 levels were above 1.7 ng/mL. We conclude that TIMP-1 and MMP-1 levels in plasma were not predictive of incident coronary artery disease in a case-cohort random sample of the Atherosclerosis Risk in Communities study, a population study of asymptomatic middle-aged adults who had no prevalent atherosclerosis upon enrollment.

Abstract
Lyme disease is a multisystem disease that can affect skin, nervous system, heart and joints. Lyme arthritis can develope in about 60% of "not treated" Lyme disease patients, 10% of patients may develope chronic arthritis. Lyme arhritis symptoms (especially chronic arthritis) is similar to rheumatoid arthritis. The purpose of this study was to establish the usefulness of examinations of serum levels of matrix metalloproteinases MMP-3, MMP-9, tissue inhibitor of metalloproteinases 1 (TIMP-1), hialuronic acid (HA) and antibodies against cyclic citrullinated peptide (anti-CCP) in Lyme arthritis, rheumatoid arthritis (RA) and patients with arthritic complaints. Plasma levels of MMP-3, HA and anti-CCP were significantly higher in RA group than in Lyme arthritis group and patients with arthritic complaints. There were no significant differences in serum levels of MMP-3, MMP-9, TIMP-1, HA, anti-CCP between Lyme arthritis patients and patients with arthritic complaints and these parameters are not usefull in differential diagnoses of Lyme arthritis.

Abstract
OBJECTIVES To study metalloproteinase activity and sex steroid hormone production in serum after intra-articular glucocorticoid treatment for knee synovitis. METHODS 18 female patients with rheumatoid arthritis and synovitis of the knee with need for intra-articular glucocorticoid treatment were included in this study. Serum samples of matrix metalloproteinases (MMP-1/TIMP complex and MMP-3), dehydroepiandrosterone sulphate, testosterone, oestradiol, steroid hormone binding globulin, follicle stimulating hormone and luteinising hormone were collected before injection with 20 mg triamcinolone hexacetonide, and 24 h, 48 h, 1 week and 2 weeks after injection, respectively. RESULTS Serum levels of MMP-3 were significantly decreased, but MMP-1/TIMP complex was unaffected. Dehydroepiandrosterone sulphate, testosterone and oestradiol levels all decreased and tended to return to baseline levels during the observation period. Steroid hormone binding globulin, follicle stimulating hormone and luteinising hormone levels were unchanged. CONCLUSIONS Intra-articular glucocorticoid treatment causes a temporary, but considerable suppression of sex steroid hormone secretion. The reduction of MMP-3 indicates an inhibition of the inflammatory, but probably also the cartilage destructive processes within the treated joint.

Abstract
OBJECTIVE To observe the effect of Gandou Decoction IV (GDIV) on serum indexes of hepatic fibrosis and liver function in patients with Wilson's disease (WD). METHODS Sixty-one WD patients were assigned to two groups, 30 patients in the sodium dimercaptosulphonate (DMPS) group and 31 patients in the GD IV group. Both groups received 8 courses of DMPS treatment with 6 days as one course, and the GD IV group was given GD IV additionally. Serum indexes of liver function were examined, serum matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) were detected by double antibody sandwish ABC enzyme-linked immunosorbent assay (ELISA), and serum hyaluronic (HA), laminin (LN), procollagen III (PC III) and collagen type IV (C-IV) were determined by radioimmunoassay (RIA). RESULTS After treatment, all indexes of hepatic fibrosis and liver function had no significant change in the DMPS group, while in the GD IV group, the serum TIMP-1 level markedly decreased (P <0.05), the ratio of MMP-1/TIMP-1 significantly increased (P <0.01), and serum indexes of liver function markedly decreased (P < 0.05), but the changes in serum levels of HA, LN and PCIII, as well as in serum MMP-1 and C-IV were insignificant (P> 0.05), though they showed a trend of decreasing or increasing, respectively. CONCLUSION Short-term decopper-ing treatment with DMPS alone has no significant effect on hepatic function and serum fibrosis indexes in WD patients, while combined with GD IV, it can improve liver function and display an anti-fibrosis effect through inhibiting the serum TIMP-1 level and increasing the ratio of MMP-1/TIMP-1.

Abstract
OBJECTIVES Tibolone is a tissue selective compound with estrogenic, androgenic and progestogenic properties in classical bioassays. It is used for alleviation of menopausal symptoms and for osteoporosis prophylaxis in postmenopausal women. Only few data are available regarding the effects of tibolone on the cardiovascular system. We investigated therefore the in vitro effects of tibolone and its metabolites on the vasculature under special controlled conditions, using human female coronary endothelial and smooth muscle cells. METHODS The effect on the production of the following markers in endothelial cells from human female coronary arteries was evaluated: nitric oxide synthase, prostacyclin, endothelin, plasminogen-activator-inhibitor-1 (PAI-1), E-Selectin, Intercellular adhesion molecule (ICAM-1), monocyte attracting protein-1 (MCP-1) and the precursor of matrix metalloproteinase-1 (pro-MMP-1). Tibolone, its metabolites, estradiol (E2), E2/norethisterone (NET) and E2/medroxyprogesterone acetate (MPA) were tested at 0.1 microM and 1 microM. The markers were determined by enzyme immunoassays in the cell supernatant. Cell proliferation of smooth muscle cells from female coronary artery was measured by an adenosine triphosphate-assay. RESULTS Tibolone, its 3-hydroxy metabolites, E2/NET, E2/MPA and estradiol alone had significant effects on the synthesis of all markers tested. The magnitude of the tibolone effects, however, was mostly smaller than that of E2/NET and E2/MPA. Concerning smooth muscle cells tibolone and its 3-hydroxy metabolites also elicited an inhibition of the proliferation compared to control values. The strongest effect here was found for E2/NET and E2 alone, whereas E2/MPA had no effect. CONCLUSION The results of this in vitro study conducted with cells of the most important vascular bed with respect to the problem of cardiovascular risk suggest that tibolone can positively influence the vasculature. However, these tibolone effects may depend on intact vascular cells and may vary due to the different atherosclerotic stages of the vessels. Thus, experimental studies are useful to explore mechanisms, but clearly cannot replace clinical studies.

Abstract
We studied the serum levels of receptor activator of nuclear factor-kappaB ligand (RANKL), osteoprotegerin (OPG), pro-matrix metalloproteinase (MMP) 1, MMP3, and tissue inhibitor of metalloproteinase (TIMP) 1 in patients with juvenile idiopathic arthritis (JIA) and correlated these with different disease variables. Sera of 70 patients with JIA (ILAR 2001 criteria) and 33 age- and sex-matched controls were assayed by enzyme-linked immunosorbent assay. Nonparametric tests were used for analysis of data. The subtype distribution of the JIA patients was: enthesitis-related arthritis (ERA) 24, polyarticular 22, systemic onset 13, oligoarticular 8, and others 3. The median level of RANKL, OPG, pro-MMP1, MMP3, and TIMP-1 were elevated in JIA patients as compared to controls (p < 0.001). There was no difference in levels among different types of JIA. RANKL/OPG ratio was elevated in all subtypes of JIA. MMP3/TIMP-1 ratio correlated with measures of disease activity including swollen and tender joint count, erythrocyte sedimentation rate, and disease activity score (rS 0.28, p < 0.05). Ours is the first study to show elevated RANKL in serum of patients with JIA. Further, our data suggest that patients with ERA have similar levels to other forms of JIA. Association of the MMP3/TIMP-1 ratio with disease activity suggests that it may be a useful biomarker for follow-up.

Abstract
OBJECTIVE Multiple studies have shown that matrix metalloproteases (MMPs) are involved in the pathologic reactions occurring as a consequence of cardiac transplantation, including ischemia-reperfusion injury and allograft rejection. This study sought to determine the temporal profile of MMP serum levels following cardiac transplantation. METHODS Endomyocardial biopsies and serum samples were obtained from 66 recipients at 1, 2, 3, 4, 7, 12, 24, and 52 weeks post-transplant during the routine follow-up protocol, and MMP-1, MMP-8, MMP-9, and tissue inhibitor of metalloproteases (TIMP)-1 serum concentrations were measured by enzyme-linked immunosorbent assay (ELISA). Immunosuppression comprised cyclosporine A (CyA; n=46) or tacrolimus (TAC; n=20) with mycophenolate mofetil and steroids. RESULTS Increased MMP-8, MMP-9, and TIMP-1 serum levels were observed during the first 2 weeks following transplantation compared to the later time points. MMP-1 was increased at 2 and 3 weeks post-transplant compared to all later time points. No correlation of MMP or TIMP serum concentrations with infection episodes was observed. CONCLUSIONS Early increase in MMP and TIMP serum levels following cardiac transplantation indicates involvement of these molecules in the reaction of the transplant to ischemia-reperfusion or early immunologic adaptation processes of the host. Further investigation of the relationship between MMP and TIMP serum levels and clinical conditions following transplantation including allograft rejection and hemodynamic graft function is necessary.

Abstract
BACKGROUND In rectal cancer treatment, preoperative radiotherapy has led to reduction of local recurrence, but it is associated with morbidity and increased risk for secondary tumours. Matrix metalloproteinases (MMPs) are associated with tumour progression through tissue remodeling. The aim of this study was to investigate tissue remodeling after preoperative radiotherapy and to explore possible correlations with clinical outcome. MATERIALS AND METHODS Ninety-one patients scheduled for rectal cancer surgery were included; 49% received preoperative radiotherapy three-field treatment, 5 x 5 Gy. Blood samples and biopsies from tumour and adjacent mucosa were taken during surgery. Biopsies and plasma were assayed with ELISA for MMP-1, MMP-2 and MMP-9. Clinical outcome was reviewed focusing on infections, perineal healing, fistula formation, anastomotic dehiscence, small bowel obstruction, local recurrence and distant metastases. RESULTS Compared to non-irradiated mucosa, MMP-2 (p < 0.0001), MMP-1 (p = 0.03) and MMP-9 (p = 0.04) were significantly higher in irradiated normal mucosa. Tumour tissue had higher levels of MMP-2 if irradiated (p < 0.0001). A correlation between MMP-2 levels and wound infection (p = 0.02) as well as fistula formation (p = 0.04) was found. MMP-1 in mucosa (p = 0.02) and tumour (p = 0.04) were higher in patients developing distant metastases. Plasma levels were not influenced by irradiation, but MMP-2 was higher in patients who were later developing distant metastases (p = 0.007). CONCLUSIONS Extracellular matrix remodeling after radiotherapy seems to be correlated to postoperative morbidity; MMP-2 is associated with both wound infections and fistula formation. High levels of MMP-1 in tumour and mucosa as well as MMP-2 in plasma may be correlated to risk of developing distant metastases.

Abstract
OBJECTIVE To evaluate the performance of biochemical and traditional markers in predicting radiographic progression in rheumatoid arthritis (RA). METHODS One hundred thirty-two patients with early RA were treated with nonbiologic therapies for 2 years and studied longitudinally. Genomic DNA was analyzed for presence of the shared epitope. Levels of matrix metalloproteinases (matrix metalloproteinase 1 [MMP-1], MMP-13, and MMP-3), tissue inhibitor of metalloproteinases 1 (TIMP-1), and cartilage oligomeric matrix protein (COMP) were assessed in serially obtained serum samples. The presence of pyridinoline (Pyr), deoxypyridinoline, glycosylated Pyr (Glc-Gal-Pyr), and C-telopeptide of type II collagen (CTX-II) was assessed in urine samples. Radiographs obtained at entry and at 2 years were evaluated using the modified Larsen score. RESULTS Baseline and 2-year radiographs were available from 118 patients. Larsen scores worsened during the 2 years in 50 patients, while 68 patients had no radiographic progression. Levels of a variety of biochemical markers, i.e., MMP-3, CTX-II, COMP, TIMP-1, Pyr, and Glc-Gal-Pyr, correlated significantly with radiographic progression at entry and longitudinally as assessed by area under the curve (AUC). By multivariate analysis, a model including MMP-3 and CTX-II was identified as providing the best prediction of radiographic progression at entry (predictive accuracy by receiver operating characteristic [ROC] AUC = 0.76 [95% confidence interval 0.66-0.85]), while a combination of MMP-3, CTX-II, and swollen joint count formed the best longitudinal AUC model (predictive accuracy by ROC AUC = 0.81 [95% confidence interval 0.73-0.89]). Patient-reported measures (Health Assessment Questionnaire, pain scores) were of limited use. In a subset of 50 patients who were treated with methotrexate (MTX) during the followup period, median serum MMP-3 levels decreased after the initiation of MTX therapy (P = 0.0003). CONCLUSION These results indicate that biochemical markers are useful predictors of radiographic progression in RA and that serum MMP-3 levels decrease significantly with MTX therapy. Multivariate models that include MMP-3 and CTX-II perform better than existing traditional markers in predicting radiographic outcome in RA.

Abstract
Aim of the study was to investigate interrelationship between serum markers of myocardial fibrosis: matrix metalloproteinase -1 (MMP-1), tissue inhibitor of metalloproteinase-1 (TIMP-1) and parameters of echocardiography in patients with arterial hypertension (AH) and paroxysmal form of atrial fibrillation (n=39). We revealed positive correlation of levels of TIMP-1 with thickness of interventricular septum in diastole (r=0,47, p=0,02), peak velocity of late filling of the right ventricle (r=0,46, p=0,01), and negative relation between MMP-1 levels and degree of mitral and tricuspid regurgitation (r=0,43, p=0,005 and r=0,38, p=0,04, respectively). In the group of patients with increased left ventricular myocardial mass index (LVMMI) TIMP-1 level was significantly higher than in patients with normal LVMMI (p < 0,05). In the group combining patients with concentric and eccentric LV hypertrophy TIMP-1 level was significantly higher than in the group combining patients with LV concentric remodeling and normal geometry (p < 0,05). No correlations were revealed between MMP-1 and TIMP-1 levels and parameters of diastolic dysfunction. In patients with AH increase of serum concentrations of TIMP-1 was associated with increased thickness of interventricular septum, increase of LVMMI, and with prognostically unfavorable types of LV remodeling.

Abstract
OBJECTIVES Circulating levels of matrix metalloproteinase (MMP)-10 are related to inflammation in asymptomatic subjects with cardiovascular risk factors. Whether MMP-10 is associated with the severity of atherosclerosis remains to be determined. This study examines the relationship of systemic MMP-10 levels with atherosclerotic risk factors and subclinical atherosclerosis. METHODS AND RESULTS Circulating levels of MMP-1, -9 and -10, and markers of inflammation [fibrinogen, interleukin-6, von Willebrand factor, and high-sensitivity C-reactive protein (hs-CRP)] were measured in 400 subjects (mean age 54.3 years, 77.7% men) with cardiovascular risk factors but free from clinical cardiovascular disease. Subclinical atherosclerosis was evaluated by both the mean carotid intima-media thickness (IMT) and the presence of atherosclerotic plaques with the use of B-mode ultrasound in all subjects. MMP-10 levels were positively correlated with fibrinogen (r = 0.24, P < 0.001), hs-CRP (r = 0.14, P < 0.01) and carotid IMT (r = 0.17, P < 0.01). The association between MMP-10 and IMT remained significant in multiple regression analysis (P < 0.02) when controlling for traditional atherosclerotic risk factors and inflammatory markers. Such an association was not observed for MMP-1 and -9. Subjects in the highest MMP-10 tertile had significantly higher carotid IMT (adjusted odds ratio 6.3, 95% confidence interval 1.3-31.4, P = 0.024). In addition, MMP-10 levels were significantly higher in patients with carotid plaques (n = 78) than in those with no plaques after adjusting for age and sex (P < 0.01). CONCLUSION Higher serum MMP-10 levels were associated with inflammatory markers, increased carotid IMT and atherosclerotic plaques in asymptomatic subjects. Circulating MMP-10 may be useful to identify subclinical atherosclerosis in subjects free from cardiovascular disease.
