Abstract
OBJECTIVES The objectives of this study were to assess the effect of 8 weeks of moderate-intensity aerobic training on permeability inflammatory indicators of matrix metalloproteinases (MMPs) and specific tissue inhibitors of MMPs in female migraineurs. METHODS Female migraineurs (n = 28, age 32 ± 6) were randomised into two groups: migraine with exercise training (EXE + Mig, n = 13) and migraine without exercise training (NON-EXE + Mig, n = 15). Matched healthy women were also recruited as a healthy control group (CON, n = 15). The EXE-Mig group performed 8 weeks of aerobic training. Pre and post intervention, serum matrix metalloproteinases (MMP-2 and 9) and specific tissue inhibitors of MMPs (TIMP-1 and 2) were measured. In addition, body composition indices and VO2max were determined. RESULTS Exercise training reduced serum MMP-9 in female migraineurs with between-group changes and a time x group interaction (p < 0.05). In addition, exercise training reduced the serum MMP-9/TIMP-1 ratio in female migraineurs with between-group changes and time x group interaction (p < 0.05). However, no training-induced effect was observed in serum TIMP-1, TIMP-2, MMP-2 contents (p > 0.05) and MMP-2/TIMP-2 ratio (p > 0.05). Finally, exercise training reduced body fat content, WHR and BMI, and improved VO2max (p < 0.01). CONCLUSIONS Our results demonstrated beneficial effects of aerobic exercise training on some circulatory inflammation factors (MMP9, MMP-9/TIMP-1) and some health indicators in female migraineurs, suggesting that such training can be employed as a non-pharmacological therapeutic method.

Abstract
Aims To determine the roles of matrix metallopeptidase-9 (MMP9) on human coronary artery smooth muscle cells (HCASMCs) in vitro, early beginning of atherosclerosis in vivo in diabetic mice, and drug naïve patients with diabetes. Methods Active human MMP9 (act-hMMP9) was added to HCASMCs and the expressions of MCP-1, ICAM-1, and VCAM-1 were measured. Act-hMMP9 (n=16) or placebo (n=15) was administered to diabetic KK.Cg-Ay/J (KK) mice. Carotid artery inflammation and atherosclerosis measurements were made at 2 and 10 weeks after treatment. An observational study of newly diagnosed drug naïve patients with type 2 diabetes mellitus (T2DM n=234) and healthy matched controls (n=41) was performed and patients had ultrasound of carotid arteries and some had coronary computed tomography angiogram for the assessment of atherosclerosis. Serum MMP9 was measured and its correlation with carotid artery or coronary artery plaques was determined. Results In vitro, act-hMMP9 increased gene and protein expressions of MCP-1, ICAM-1, VCAM-1, and enhanced macrophage adhesion. Exogenous act-hMMP9 increased inflammation and initiated atherosclerosis in KK mice at 2 and 10 weeks: increased vessel wall thickness, lipid accumulation, and Galectin-3+ macrophage infiltration into the carotid arteries. In newly diagnosed T2DM patients, serum MMP9 correlated with carotid artery plaque size with a possible threshold cutoff point. In addition, serum MMP9 correlated with number of mixed plaques and grade of lumen stenosis in coronary arteries of patients with drug naïve T2DM. Conclusion MMP9 may contribute to the initiation of atherosclerosis and may be a potential biomarker for the early identification of atherosclerosis in patients with diabetes.

Abstract
PURPOSE Radiotherapy showed the potential to effectively kill the cysts of pulmonary cystic echinococcosis (CE). However, little is known about its safety. This study was designed to investigate the safety of three-dimensional conformal radiotherapy (3D-CRT) on the normal lung tissue adjacent to the cyst and blood of sheep naturally infected with pulmonary CE. METHODS Twenty pulmonary CE sheep were randomly divided into control group (n = 5) and radiation groups with a dose of 30 Gray (Gy) (n = 5), 45 Gy (n = 5), and 60 Gy (n = 5), respectively. Animals in control group received no radiation. Heat shock protein 70 (Hsp70), tumor growth factor-β (TGF-β), matrix metalloproteinase-2 (MMP-2) and MMP-9 in the lung tissues adjacent to the cysts, which were considered to be closely related to the pathogenesis of CE, were evaluated after 3D-CRT. A routine blood test was conducted. RESULTS The results showed that there were multiple cysts of various sizes with protoscoleces in the lung tissues of sheep, and necrotic cysts were found after 3D-CRT. 3D-CRT significantly increased the mRNA level of Hsp70, enhanced the protein level of TGF-β and slightly increased the expression of MMP-2 and MMP-9 in lung tissues adjacent to the cysts. 3D-CRT did not significantly alter the amount of WBC, HB and PLT in sheep blood. CONCLUSIONS The results suggested that 3D-CRT may suppress the inflammation and induce less damage of the normal lung tissues and blood. We preliminarily showed that 3D-CRT under a safe dose may be used to treat pulmonary CE.

Abstract
Background The progression of COVID-19 has different clinical presentations, which raises a number of immunological questions. Objectives This study aimed to investigate MMP-9 and TIMP-1 levels in patients diagnosed with COVID-19 and whether the MMP-9/TIMP-1 ratio is associated with lung involvement in COVID-19. Methods This study was conducted with 192 patients and 45 healthy controls. ELISA was used to measure the MMP-9 and TIMP-1. Results The MMP-9 and TIMP-1 levels of the patients were found to be higher than those of the controls. MMP-9 and TIMP-1 were detected more in patients with lung involvement on chest CT scans than in those with no lung involvement on chest CT scans. A comparison of lung involvement levels revealed no difference was found between the groups. The MMP-9/TIMP-1 ratio was 5.8 in the group with lung involvement on chest CT scans and 6.1 in the group without lung involvement on chest CT scans. No difference was found between the two groups. A comparison with respect to lung involvement levels showed that the MMP-9/TIMP-1 ratio difference was found between the groups. Conclusion Diagnostic and treatment methods targeting MMP-9 activity or neutrophil activation may be important in predicting lung involvement in COVID-19 and directing clinical outcomes.

Abstract
Congenitally deaf children who undergo cochlear implantation before 1 year of age develop their auditory skills faster than children who are implanted later. In this longitudinal study, a cohort of 59 implanted children were divided into two subgroups according to their ages at implantation-below or above 1 year old-and the plasma levels of matrix metalloproteinase-9 (MMP-9), brain-derived neurotrophic factor (BDNF), and pro-BDNF were measured at 0, 8, and 18 months after cochlear implant activation, while auditory development was simultaneously evaluated using the LittlEARs Questionnaire (LEAQ). A control group consisted of 49 age-matched healthy children. We identified statistically higher BDNF levels at 0 months and at the 18-month follow-ups in the younger subgroup compared to the older one and lower LEAQ scores at 0 months in the younger subgroup. Between the subgroups, there were significant differences in the changes in BDNF levels from 0 to 8 months and in LEAQ scores from 0 to 18 months. The MMP-9 levels significantly decreased from 0 to 18 months and from 0 to 8 months in both subgroups and from 8 to 18 months only in the older one. For all measured protein concentrations, significant differences were identified between the older study subgroup and the age-matched control group.

Abstract
Aging is accompanied by a low-grade proinflammatory status that plays a role in age-related vascular alterations. Syndecan-4 (SDC4) is a key component of the endothelial glycocalyx, and its extracellular domain can be shed by matrix metalloproteinase-9 (MMP-9). In vitro studies demonstrated that MMP-9-mediated shedding of SDC4 is induced by tumor necrosis factor-α (TNF- α) in human endothelial cells. However, the relationship between circulating shed SDC4, systemic inflammation, and age-related vascular alterations remains unknown. Here, we used linear regression models to examine the associations of serum SDC4 levels with cardiovascular hemodynamic phenotypes, serum MMP-9, and serum TNF-α and inteleukin-6 in healthy older women (n = 74). Serum SDC4 was not associated with proinflammatory cytokines or arterial elasticity. Nevertheless, we found significant correlations of SDC4 with MMP-9, heart rate, left ventricular ejection time, systemic vascular resistance, and blood pressure. Our preliminary evidence suggests that systemic inflammation might not induce SDC4 shedding in healthy aging.

Abstract
Background The role of the long non-coding RNAs (lncRNAs) in the pathogenesis of systemic lupus erythematosus (SLE) is mostly unknown, despite increasing evidence that lncRNAs extensively participate in physiological and pathological conditions. Aim To detect the level of lncRNA-Cox2, HOTAIR, IL-6, and MMP-9 in the serum of SLE patients and to correlate these levels with disease activity and patients’ clinical and laboratory data to evaluate the value of these biomarkers for SLE diagnosis and assessment of disease activity. Methods Blood samples from 58 SLE patients, and 60 healthy controls (HCs) were used for detection of lncRNAs-Cox2 and HOTAIR expression levels by real-time polymerase chain reaction. Both IL-6 and MMP-9 serum levels were assayed by enzyme-linked immunosorbent assay. Lupus activity was assessed with the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Results The serum expression levels of lncRNA-Cox2 and HOTAIR were significantly up-regulated in SLE patients vs HCs (fold change [median (IQR) was 1.29(0.81–1.71, P<0.0001) and 2.68(0.95–3.67), P = 0.038) for lncRNA-Cox2 and HOTAIR, respectively. Serum levels of both IL-6 and MMP-9 were significantly high in SLE patients compared with HCs (P≤0.001 for each). The up-regulated lncRNA-Cox2 was positively associated with the presence of neurological manifestations in SLE patients (P = 0.007). Furthermore, HOTAIR expression level had significantly positive correlation with IL-6 (r = 0.578, P<0.0001), MMP-9 level (r = 0.762, P<0.0001), nephritis grades (r = 0.296, P = 0.024) and proteinuria (r = 0.287, P = 0.035). LncRNA-Cox2 showed sensitivity and specificity 72.4%, and 100.0% respectively. HOTAIR sensitivity was 60.3%, and specificity was 100.0%. By multiple logistic regression analysis, lncRNA-Cox2 and HOTAIR were found as SLE independent predictors. Conclusion LncRNA-COX2 and HOTAIR can be used as new non-invasive biomarkers for the diagnosis of SLE.

Abstract
Both angiogenesis and inflammation contribute to activation of matrix metalloproeteinase-9 (MMP-9), which dissolves the extracellular matrix, disrupts the blood-brain barrier, and plays an important role in the pathogenesis of brain arteriovenous malformations (BAVMs). The key common cytokine in both angiogenesis and inflammation is interleukin 6 (IL-6). Previous studies have shown elevated systemic MMP-9 and decreased systemic vascular endothelial growth factor (VEGF) in BAVM patients. However, the clinical utility of plasma cytokines is unclear. The purpose of this study is to explore the relationship between plasma cytokines and the clinical presentations of BAVMs. Prospectively, we recruited naive BAVM patients without hemorrhage as the experimental group and unruptured intracranial aneurysm (UIA) patients as the control group. All patients received digital subtraction angiography, and plasma cytokines were collected from the lesional common carotid artery. Plasma cytokine levels were determined using a commercially available, monoclonal antibody-based enzyme-linked immunosorbent assay. Subgroup analysis based on hemorrhagic presentation and angiograchitecture was done for the BAVM group. Pearson correlations were calculated for the covariates. Means and differences for continuous and categorical variables were compared using Student's t and χ2 tests respectively. Plasma MMP-9 levels were significantly higher in the BAVM group (42,945 ± 29,991 pg/mL) than in the UIA group (28,270 ± 17,119 pg/mL) (p < 0.001). Plasma MMP-9 levels in epileptic BAVMs (57,065 ± 35,732; n = 9) were higher than in non-epileptic BAVMs (35,032 ± 28,301; n = 19) (p = 0.049). Lower plasma MMP-9 levels were found in cases of BAVM with angiogenesis and with peudophlebitis. Plasma MMP-9 is a good biomarker reflecting ongoing vascular remodeling in BAVMs. Angiogenesis and pseudophlebitis are two angioarchitectural signs that reflect MMP-9 activities and can potentially serve as imaging biomarkers for epileptic BAVMs.

Abstract
UNLABELLED Ischemic stroke is the main cause of permanent disability in adult patients. No commonly accepted method were discovered to predict stroke before the first symptoms. Activation of matrix metalloproteinases (MMPs), tissue inhibitor of metalloproteinases (TIMP) and S100B protein may be observe in patients with symptomatic carotid artery stenosis. Hemorrhagic transformation of ischemic stroke may be associated with changes in MMP, TIMP and S100B. AIM The aim of this study was to determine if MMP-9, TIMP-1 and S-100B protein may markers of forthcoming ischemic stroke in patients undergoing carotid endarterectomy. MATERIALS AND METHODS Blood samples were taken and an analysis of circulating proteins (MMP-9, TIMP-1, S100B) 73 subsequent patients with carotid artery stenosis ≥70% (33 asymptomatic and 40 symptomatic), who were referred for potential revascularization. RESULTS A statistically significant difference was found between MMP- 9 levels in patients with ischemic stroke compared to patients with asymptomatic carotid stenosis after endarterectomy. Also, average TIMP-1 levels in patients with ischemic stroke and stenosis ≥70% were statistically significantly higher than the average levels in patients after endarterectomy. In terms of S-100B, a higher mean value was observed in patients with stroke than in endarterectomy group. No statistical differences were found in the levels of that proteins in the hemorrhagic transformation of ischemic stroke. CONCLUSIONS Increased levels of MMP-9, TIMP-1 and S-100B in patients with ischemic stroke compared to patients with asymptomatic carotid stenosis after endarterectomy showed that abovementioned proteins may be a good predictive factor of ischemic stroke in patients undergoing carotid endarterectomy.

Abstract
Background: Alcohol consumption by adolescents is responsible for a number of adverse health and social outcomes. Despite the well-established effect of alcohol use on the development of alcoholic liver disease, the relationship between the pattern of alcohol consumption and liver fibrosis is still unclear. This study is a follow-up to work on liver damage from alcohol intoxication. The aim of our study was to explore the early effects of alcohol intoxication on liver fibrosis in adolescents. Methods: The prospective study included 57 adolescents aged 14−17 years admitted to the emergency department (ED) from February 2017 to June 2018 due to acute alcohol intoxication. Serum levels of amino terminal propeptide of type III procollagen (PIIINP), type IV collagen, matrix metallopeptidase 9 (MMP-9) and tissue inhibitor of metalloproteinase 1 (TIMP-1) were determined by enzyme-linked immunosorbent assays. Results: There were significant differences in MMP-9 (p = 0.02) and TIMP-1 (p = 0.007) levels between the study and control groups. Liver parameters and selected markers of fibrosis were similar in groups in terms of blood alcohol concentrations (BAC). MMP-9 was positively correlated with alanine aminotransferase (ALT) (r = 0.38; p = 0.004) and total bilirubin (r = 0.39; p = 0.004). Positive significant correlations were also found between TIMP-1 and ALT (r = 0.47; p < 0.001), AST (r = 0.29; p = 0.03) and total bilirubin (r = 0.32; p = 0.02). In receiver operating characteristic (ROC) analysis, MMP-9 (AUC = 0.67, p = 0.02) and TIMP-1 (AUC = 0.69, p = 0.003) allowed for the differentiation of patients with and without alcohol intoxication. Conclusion: Our results show that even a single episode of alcohol intoxication in adolescents can lead to imbalance in markers of fibrosis.

Abstract
The aim of the present study was to evaluate the effect of Compound 21 (C21), a selective AT2R agonist, on the prevention of endothelial dysfunction, extracellular matrix (ECM) remodeling and arterial stiffness associated with diet-induced obesity (DIO). Five-week-old male C57BL/6J mice were fed a standard (Chow) or high-fat diet (HF) for 6 weeks. Half of the animals of each group were simultaneously treated with C21 (1 mg/kg/day, in the drinking water), generating four groups: Chow C, Chow C21, HF C, and HF C21. Vascular function and mechanical properties were determined in the abdominal aorta. To evaluate ECM remodeling, collagen deposition and TGF-β1 concentrations were determined in the abdominal aorta and the activity of metalloproteinases (MMP) 2 and 9 was analyzed in the plasma. Abdominal aortas from HF C mice showed endothelial dysfunction as well as enhanced contractile but reduced relaxant responses to Ang II. This effect was abrogated with C21 treatment by preserving NO availability. A left-shift in the tension-stretch relationship, paralleled by an augmented β-index (marker of intrinsic arterial stiffness), and enhanced collagen deposition and MMP-2/-9 activities were also detected in HF mice. However, when treated with C21, HF mice exhibited lower TGF-β1 levels in abdominal aortas together with reduced MMP activities and collagen deposition compared with HF C mice. In conclusion, these data demonstrate that AT2R stimulation by C21 in obesity preserves NO availability and prevents unhealthy vascular remodeling, thus protecting the abdominal aorta in HF mice against the development of endothelial dysfunction, ECM remodeling and arterial stiffness.

Abstract
Background/Aims Non-alcoholic fatty liver disease (NAFLD) represents a significant public health issue. Identifying patients with simple steatosis from those with non-alcoholic steatohepatitis (NASH) is crucial since NASH is correlated with increased morbidity and mortality. Serum-based markers, including adipokines and cytokines, are important in the pathogenesis and progression of NAFLD. Here we assessed the usefulness of such markers in patients with NAFLD. Methods This prospective, cross-sectional study included 105 adult patients with varying severity of NAFLD. Twelve serum-based markers were measured by 3 biochip platforms and 2 enzyme-linked immunosorbent assay (ELISA) methods. We also developed a NAFLD individual fibrosis index (NIFI) using the serum-based markers mostly correlated with fibrosis severity. Results Sixty-one out of 105 patients were male (58.1%) with mean age was 53.5 years. Higher Interleukin-6 (IL-6) increased (p = 0.0321) and lower Matrix Metalloproteinase-9 (MMP-9) serum levels (p = 0.0031) were associated with higher fibrosis as measured by Fibroscan® in multivariable regression analysis. Using receiver-operating characteristic (ROC) curve analysis for the NIFI, area under the curve for predicting Fibroscan values ≥ 7.2 kPa was 0.77 (95%CI: 0.67, 0.88, p<0.001), with sensitivity of 89.3%, specificity of 57.9% and a positive likelihood ratio of 2.8. Conclusions Increasing fibrosis severity in NAFLD is associated with differential expression of IL-6 and MMP-9. NIFI could be valuable for the prediction of advanced NAFLD fibrosis and potentially help avoid unnecessary interventions such as liver biopsy in low-risk patients.

Abstract
OBJECTIVE HIV and hepatitis B virus (HBV) coinfection can accelerate morbidity and mortality, especially in sub-Saharan Africa where both infections are common. Although inflammation contributes to disease progression, more information is needed to better understand the pathology. This study compared markers of cirrhosis and inflammation in HIV/HBV-coinfected individuals compared with monoinfected and uninfected patients. SETTING The HIV/HBV-coinfected subjects from the Ugandan arm of the prospective African Cohort Study were selected for evaluation and matched by age and gender with HIV-monoinfected, HBV-monoinfected, and uninfected controls. METHODS Plasma samples were used to quantify markers of immune activation and inflammation. The FIB-4 (a simple index to predict significant liver fibrosis) score was used to estimate liver fibrosis. Demographic and laboratory characteristics were compared across the groups. RESULTS Together, 31 HIV/HBV-coinfected participants were identified and compared with 62 HIV-monoinfected, 7 HBV-monoinfected, and 62 uninfected controls. The HIV/HBV-coinfected group had generally higher levels of inflammation. Most notably, matrix metalloproteinase-2, matrix metalloproteinase-9, and fibroblast growth factor-19 levels were dysregulated among the HIV/HBV-coinfected individuals. Furthermore, the FIB-4 score was higher in the HIV/HBV-coinfected group compared with the HIV-monoinfected group and revealed that 11% of HIV/HBV-coinfected individuals had evidence of undiagnosed advanced liver disease. CONCLUSIONS Differences in levels of inflammation exist between individuals with HIV/HBV coinfection compared with monoinfected and uninfected controls. A distinct signature of inflammation was associated with HIV/HBV coinfection that could reflect the mechanism of liver fibrosis and increased risk for disease progression. Finally, there may be an underappreciated amount of undiagnosed advanced liver disease in sub-Saharan Africa.

Abstract
Tick-borne encephalitis (TBE) is an acute disease caused by the tick-borne encephalitis virus. Due to the viral nature of the condition, there is no effective causal treatment for full-blown disease. Current and nonspecific TBE treatments only relieve symptoms. Unfortunately, the first phase of TBE is characterized by flu-like symptoms, making diagnosis difficult during this period. The second phase is referred to as the neurological phase as it involves structures in the central nervous system-most commonly the meninges and, in more severe cases, the brain and the spinal cord. Therefore, it is important that early markers of TBE that will guide clinical decision-making and the choice of treatment are established. In this review, we performed an extensive search of literature reports relevant to biomarkers associated with TBE using the MEDLINE/PubMed database. We observed that apart from routinely determined specific immunoglobulins, free light chains may also be useful in the evaluation of intrathecal synthesis in the central nervous system (CNS) during TBEV infection. Moreover, selected metalloproteinases, chemokines, or cytokines appear to play an important role in the pathogenesis of TBE as a consequence of inflammatory reactions and recruitment of white blood cells into the CNS. Furthermore, we reported promising findings on tau protein or Toll-like receptors. It was also observed that some people may be predisposed to TBE. Therefore, to understand the role of selected tick-borne encephalitis biomarkers, we categorized these factors and discussed their potential application in the diagnosis, prognosis, monitoring, or management of TBE.

Abstract
OBJECTIVES The aim of the study was to analyze some metalloproteinases, cytokines, and chemokines in LB patients and healthy seropositive subjects. The presence of IgM/IgG antibodies against specific Borreliella antigens was analyzed in the presence or absence of clinical manifestations of LB. MATERIAL AND METHODS The study involved 38 patients diagnosed with LB and arthralgia and/or arthritis symptoms, and 57 foresters presenting no clinical symptoms of LB. The ELISA test was applied for general screening of anti-Borreliella IgM/IgG. Western blot was used for confirmatory diagnosis of LB for the positive and borderline results. Serum IL-2, IL-4, IL-6, IL-10, IL-17A, IFN-γ, TNF, IL-8, CCL5, CXCL9/MIG, CCL2/MCP-1, CXCL10/IP-10 concentrations were measured with the use of the Human Cytometric CBA test. The concentration of MMP-2 and MMP-9 in the serum was determined with the use of ELISA tests. RESULTS Analysis of the cytokines and chemokines revealed that only the concentration of IL-2 was significantly higher (2.4 pg/m; p=0.00641) in patients with LB symptoms than in the seropositive individuals (0.4 pg/ml). The MMP2 concentration was significantly higher (233.3 ng/ml; p=0.00294) in patients with clinical manifestations of LB than in those occupationally exposed to tick bites, but did not have anti-Borreliella antibodies (192.0 ng/ml). CONCLUSIONS The presence of IgG antibodies against a number of Borreliella antigens and the differences in the IL-2 and MMP2 levels in seropositive or seronegative individuals and symptomatic LB patients, may indicate differences in the intensity of the immune response to the infection and, consequently, may induce development of clinical manifestations of the disease in seropositive and seronegative individuals.

Abstract
BACKGROUND Early diagnosis of hepatic encephalopathy (HE) in chronic liver disease (CLD) is difficult clinically. OBJECTIVE The aim of this study was to evaluate whether serum matrix metalloproteinase-9 (MMP-9) levels could identify early HE in patients with CLD. METHODS Serum MMP-9 levels in 1,187 patients with CLD were measured at baseline. A total of 1,187 patients with CLD were followed for a mean of 48 months (range: 4-50). The association between MMP-9 and the risk of HE was evaluated by logistic regression analysis and Cox regression analysis. RESULTS Patients with higher serum MMP-9 levels had higher rates of HE history and HE events during follow-up (all P<0.001). The multivariate logistic regression analysis revealed that MMP-9 (OR=2.84, 95% CI 1.63-7.11, P=0.004) was independently associated with HE history, with an increased grade of aggravation on liver fibrosis at baseline. Multivariate Cox proportional hazard analysis revealed that MMP-9 (HR=2.21, 95% CI 1.09-5.02, P<0.001) was an independent predictor for HE events by sensitivity analysis. The Kaplan-Meier analysis demonstrated that patients with MMP-9 above the median value (176.2 mg/d) had a higher rate of new HE events than patients who had MMP-9 levels below the median value (P<0.001). CONCLUSIONS Elevated serum RBP4 levels were associated with a higher risk of HE events during follow-up. These results may suggest that serum MMP-9 has good predictive value for detecting HE in patients with CLD, which provides some clinical reference value to clinicians for the early diagnosis of HE.

Abstract
Serum biomarkers are associated with hemorrhagic transformation and brain edema after cerebral infarction. However, whether serum biomarkers predict hemorrhagic transformation in large vessel occlusion stroke even after mechanical thrombectomy, which has become widely used, remains uncertain. In this prospective study, we enrolled patients with large vessel occlusion stroke in the anterior circulation. We analyzed 91 patients with serum samples obtained on admission. The levels of matrix metalloproteinase-9 (MMP-9), amyloid precursor protein (APP) 770, endothelin-1, S100B, and claudin-5 were measured. We examined the association between serum biomarkers and hemorrhagic transformation within one week. Fifty-four patients underwent mechanical thrombectomy, and 17 patients developed relevant hemorrhagic transformation (rHT, defined as hemorrhagic changes ≥ hemorrhagic infarction type 2). Neither MMP-9 (no rHT: 46 ± 48 vs. rHT: 15 ± 4 ng/mL, P = 0.30), APP770 (80 ± 31 vs. 85 ± 8 ng/mL, P = 0.53), endothelin-1 (7.0 ± 25.7 vs. 2.0 ± 2.1 pg/mL, P = 0.42), S100B (13 ± 42 vs. 12 ± 15 pg/mL, P = 0.97), nor claudin-5 (1.7 ± 2.3 vs. 1.9 ± 1.5 ng/mL, P = 0.68) levels on admission were associated with subsequent rHT. When limited to patients who underwent mechanical thrombectomy, the level of claudin-5 was higher in patients with rHT than in those without (1.2 ± 1.0 vs. 2.1 ± 1.7 ng/mL, P = 0.0181). APP770 levels were marginally higher in patients with a midline shift ≥ 5 mm than in those without (79 ± 29 vs. 97 ± 41 ng/mL, P = 0.084). The predictive role of serum biomarkers has to be reexamined in the mechanical thrombectomy era because some previously reported serum biomarkers may not predict hemorrhagic transformation, whereas the level of APP770 may be useful for predicting brain edema.

Abstract
BACKGROUNDNecrotizing soft-tissue infections (NSTIs) are rapidly progressing infections frequently complicated by septic shock and associated with high mortality. Early diagnosis is critical for patient outcome, but challenging due to vague initial symptoms. Here, we identified predictive biomarkers for NSTI clinical phenotypes and outcomes using a prospective multicenter NSTI patient cohort.METHODSLuminex multiplex assays were used to assess 36 soluble factors in plasma from NSTI patients with positive microbiological cultures (n = 251 and n = 60 in the discovery and validation cohorts, respectively). Control groups for comparative analyses included surgical controls (n = 20), non-NSTI controls (i.e., suspected NSTI with no necrosis detected upon exploratory surgery, n = 20), and sepsis patients (n = 24).RESULTSThrombomodulin was identified as a unique biomarker for detection of NSTI (AUC, 0.95). A distinct profile discriminating mono- (type II) versus polymicrobial (type I) NSTI types was identified based on differential expression of IL-2, IL-10, IL-22, CXCL10, Fas-ligand, and MMP9 (AUC >0.7). While each NSTI type displayed a distinct array of biomarkers predicting septic shock, granulocyte CSF (G-CSF), S100A8, and IL-6 were shared by both types (AUC >0.78). Finally, differential connectivity analysis revealed distinctive networks associated with specific clinical phenotypes.CONCLUSIONSThis study identifies predictive biomarkers for NSTI clinical phenotypes of potential value for diagnostic, prognostic, and therapeutic approaches in NSTIs.TRIAL REGISTRATIONClinicalTrials.gov NCT01790698.FUNDINGCenter for Innovative Medicine (CIMED); Region Stockholm; Swedish Research Council; European Union; Vinnova; Innovation Fund Denmark; Research Council of Norway; Netherlands Organisation for Health Research and Development; DLR Federal Ministry of Education and Research; and Swedish Children's Cancer Foundation.

Abstract
Memantine was suggested as a promising treatment for stroke due to its neuroprotective property and efficacy in reducing ischemic brain injury and improving post-ischemic neurological recovery. This pilot, open-label, randomized clinical trial was conducted to investigate the impact of memantine on serum concentrations of matrix metalloproteinases (MMP)-2 and MMP-9, as neuronal damage biomarkers, and neurologic function evaluated by the National Institute of Health Stroke Scale(NIHSS) and Barthelindex(BI) in patients with ischemic stroke. Admitted patients with mild to moderate ischemic stroke were assessed for eligibility, and eligible patients were randomized to the intervention or control group. Enrolled patients in the intervention group received 20 mg memantine every 8 h for five days and then 20 mg daily for three months. Both groups managed with the standard treatments. From 77 randomized patients, 29 participants in the control group and 24 patients in the intervention group completed the study. Data showed that the increase in the serum concentrations of MMP-9 within the first 5 days of the study was significantly lower in the intervention group (P = 0.005). This effect of memantine on the MMP-2 was not significant (P = 0.448). memantine also could significantly improve the neurologic function of the patients according to NIHSS (P < 0.0001) and BI (P = 0.002) during hospitalization and after that. In conclusion, memantine could be considered as a neuroprotective agent in patients with mild to moderate ischemic stroke, based on its significant effects on reducing brain damage and improving neurologic function of the patients.

Abstract
INTRODUCTION Microribonucleic acids (miRNAs) have short (approximately 18 to 25) nucleotides and are evolutionarily conserved and endogenously expressed RNAs belonging to a family of noncoding RNA molecules. miRNA-373 regulates cell proliferation, migration, apoptosis, invasion, and repairing damaged DNA after hypoxia stress. Neonatal hypoxic-ischemic encephalopathy (HIE) refers to perinatal asphyxia caused by partial or complete hypoxia, reduced or suspended cerebral blood flow, and fetal or neonatal brain damage. We aim to investigate the relationship between miRNA-373 and HIF-1α, between miRNA-373 MMP-9, and between miRNA-373 VEGF in the occurrence and development of HIE. METHODS Human (children) samples were divided into four groups (n = 15 in each group) according to HIE severity. The patient group was divided into middle, moderate, and severe HIE groups. The control group included healthy children or children with nonneurological diseases. The expressions of miRNA-373, HIF-1α, MMP-9, and VEGF were assayed in the serum samples. RESULTS Our study showed a strong relationship between miRNA-373 and HIF-1α, between miRNA-373 and MMP-9, and between miRNA-373 and VEGF. The expression levels of miRNA-373, HIF-1α, MMP-9, and VEGF in the HIE groups were much higher than those of the control group. CONCLUSION The increased change in miRNA-373 expression has a certain diagnostic significance on neonatal HIE. In the occurrence and development of HIE, miRNA-373 is positively correlated with HIF-1α, MMP-9, and VEGF.

Abstract
BACKGROUND The discovery that nerve growth factor (NGF) metabolism is altered in Down syndrome (DS) and Alzheimer's disease (AD) brains offered a framework for the identification of novel biomarkers signalling NGF deregulation in AD pathology. METHODS We examined levels of NGF pathway proteins (proNGF, neuroserpin, tissue plasminogen activator [tPA], and metalloproteases [MMP]) in matched cerebrospinal fluid (CSF)/plasma samples from AD-symptomatic (DSAD) and AD-asymptomatic (aDS) individuals with DS, as well as controls (HC). RESULTS ProNGF and MMP-3 were elevated while tPA was decreased in plasma from individuals with DS. CSF from individuals with DS showed elevated proNGF, neuroserpin, MMP-3, and MMP-9. ProNGF and MMP-9 in CSF differentiated DSAD from aDS (area under the curve = 0.86, 0.87). NGF pathway markers associated with CSF amyloid beta and tau and differed by sex. DISCUSSION Brain NGF metabolism changes can be monitored in plasma and CSF, supporting relevance in AD pathology. These markers could assist staging, subtyping, or precision medicine for AD in DS.

Abstract
Matrix metalloproteinase-9 (MMP-9) has been shown to play a key role in endothelial function and perhaps pivotal in the correlation between periodontal disease and cardiovascular disease (CVD). For the study, the impact of MMP-9 of periodontitis and CVD on serum and saliva concentrations was analyzed. For the study patients with periodontitis (n = 31), CVD (n = 31), periodontitis + CVD (n = 31), and healthy patients (n = 31) were enrolled. Clinical and demographic characteristics as well as serum and salivary MMP-9 were evaluated. MMP-9 concentrations in serum and saliva were statistically elevated in patients with CVD (p < 0.01) and in patients with periodontitis plus CVD (p < 0.001) compared to patients with periodontitis and healthy subjects. Multivariate regression analysis showed that c-reactive protein (hs-CRP) was the only significant predictor for MMP-9 serum (p < 0.001), whereas hs-CRP (p < 0.001) and total cholesterol (p = 0.029) were the statistically significant salivary MMP-9 predictors. This study evidenced that patients with CVD and periodontitis + CVD presented elevated MMP-9 concentrations in serum and saliva compared to patients with periodontitis and healthy subjects. Furthermore, hs-CRP was a negative predictor of serum and salivary MMP-9.

Abstract
BACKGROUND Tissue inhibitor of metalloproteinase-1 (TIMP-1) has been suggested as a marker for abnormal regulation of tissue remodelling in type 1 diabetes. Metalloproteinase-9 (MMP-9) has been associated with matrix turnover, and Neutrophil gelatinase associated lipocalin (NGAL) is a marker of tubular injury in diabetic nephropathy. The aim was to analyse these biomarkers to unmask early diabetic complications. METHODS Thirty-three type 1 diabetes patients, aged 20-35 years, and disease duration 20 ± 5.3 years were included. Along with clinical examination, neurophysiological measurements, routine biochemistry, plasma concentrations of TIMP-1, MMP-9 and NGAL were determined with immunoenzymatic techniques. RESULTS TIMP-1 correlated with abnormal unilateral and bilateral vibratory sense foot perception (r = -0.49 and r = -0.51, respectively), foot neuropathy impairment assessment score (NIA; r = -0.55), neuropathy symptom assessment score (r = 0.42), microalbuminuria (r = 0.50) and eGFR (r = -0.45). MMP-9 correlated with impaired foot NIA (r = 0.51). Multiple regression analysis showed an association for TIMP-1 (p = 0.004) with impaired neurophysiological examinations and renal dysfunction along with NGAL (p = 0.016 and p = 0.015 respectively). CONCLUSIONS This study suggests that plasma levels of TIMP-1, MMP-9 and NGAL may serve as useful biomarkers in unravelling subclinical neuropathy and nephropathy in type 1 diabetes.

Abstract
Substance-P (SP) is a neuropeptide that modulates immune responses and accelerates tissue repair in critical inflammatory disease. Liver fibrosis and cirrhosis are the ultimate outcomes of almost all chronic liver diseases caused by viral infection, steatohepatitis, autoimmune, and cholestatic injury. Despite the development of new drugs, liver transplantation is still the only fundamental treatment; thus, new therapeutic approaches to mitigate liver fibrosis and chronic inflammation are constantly being needed. The aim of this study was to examine the effect of SP on liver damage due to cholestatic stress. To induce cholestatic injury, common bile duct ligation (CBDL) was attempted, followed by systemic application of SP. SP treatment increased IL-10 and decreased TNF-α in serum with increasing levels of circulating regulatory T cells (Tregs) from the early stage of CBDL. Moreover, SP decreased CBDL-induced TGF-β1 expression in the circulation. This could create anti-inflammatory/anti-fibrotic environment under CBDL, which might ameliorate the progression of liver fibrosis in CBDL. Histological and molecular analysis revealed that SP treatment reduced ductular reaction, hepatic damage, and apoptotic hepatocytes, accompanied by diminishing type I collagen and upregulating MMP-9. These studies found that SP is a promising therapeutic candidate for immune-related liver disease as well as cholestatic liver disease, by providing hepatic protective effects via immune suppression.

Abstract
BACKGROUND AND AIMS Whether the prognostic value of matrix metalloproteinase-9 (MMP-9) is modified by patients' dyslipidemia status is unknown. The aim of present study was to evaluate the prognostic effect of MMP-9 among ischemic stroke patients stratified by dyslipidemia status. METHODS AND RESULTS MMP-9 levels were measured for 2977 acute ischemic stroke patients from 26 participating hospitals across China, and data of clinical outcomes within one year after ischemic stroke was collected. The primary outcome was a composite outcome of major disability and death at one year after stroke onset, and secondary outcomes were major disability, death, vascular events and recurrent stroke. The association between MMP-9 and primary outcome was appreciably modified by dyslipidemia status (Pinteraction = 0.048). After multivariate adjustment, increased MMP-9 level was associated with increased risk of primary outcome at one year after ischemic stroke in the patients with dyslipidemia (odds ratio, 1.34; 95% confidence interval, 1.06-1.79), but not in those without dyslipidemia (odds ratio, 1.23; 95% confidence interval, 0.90-1.68). Increased MMP-9 was also significantly associated with major disability, death and vascular events in the patients with dyslipidemia but not in those without dyslipidemia (P for interaction < 0.05 for all). CONCLUSION Increased MMP-9 was associated with poor prognosis within one-year after stroke only in patients with dyslipidemia, suggesting that the prognostic value of MMP-9 be modified by dyslipidemia status of ischemic stroke patients. Further prospective study from other populations and randomized clinical trials are needed to verify our findings and clarify the potential mechanisms.

Abstract
Matrix metalloproteinases (MMPs) are enzymes with critical roles in biology and pathology. Glycosylation, nitrosylation and proteolysis are known posttranslational modifications (PTMs) regulating intrinsically the activities of MMPs. We discovered MMP citrullination by peptidyl arginine deiminases (PADs) as a new PTM. Upon hypercitrullination, MMP-9 acquired a higher affinity for gelatin than control MMP-9. Furthermore, hypercitrullinated proMMP-9 was more efficiently activated by MMP-3 compared to control MMP-9. JNJ0966, a specific therapeutic inhibitor of MMP-9 activation, inhibited the activation of hypercitrullinated proMMP-9 by MMP-3 significantly less in comparison with control proMMP-9. The presence of citrullinated/homocitrullinated MMP-9 was detected in vivo in neutrophil-rich sputum samples of cystic fibrosis patients. In addition to citrullination of MMP-9, we report efficient citrullination of MMP-1 and lower citrullination levels of MMP-3 and MMP-13 by PAD2 in vitro. In conclusion, citrullination of MMPs is a new PTM worthy of additional biochemical and biological studies.

Abstract
Matrix metalloproteinases (MMPs) are important in the pathogenesis of numerous diseases. The present study aimed to monitor the activation of MMP-2 and MMP-9 in spontaneously hypertensive rats (SHR) and their normotensive counterparts-Wistar-Kyoto rats (WKY). The animals were divided according to age (7, 20, and 52 weeks) and phenotype into: WKY-7, WKY-20, WKY-52, SHR-7, SHR-20 and SHR-52 groups. MMP plasma activities were determined by gelatine zymography. We monitored selected parameters of oxidative stress and antioxidant status. N-terminal pro-brain natriuretic peptide (NT-proBNP) was determined as a marker of heart function and neurohumoral activation. SHR-7 showed higher MMP-2 activity compared with WKY-7, while SHR-52 showed lower MMP-2 and MMP-9 activities compared with WKY-52. Examining age-dependent changes in MMP activities, we found a decrease in MMP-2 activity and increase in MMP-9 activity with increasing age in both phenotypes. Parameters of oxidative stress and antioxidant status as well as NT-proBNP levels were not significantly worsened due to aging in SHR. Our results suggest that hypertension is accompanied by varying MMP activation during aging. The results of our study may indicate that MMP-2 inhibition is therapeutically applicable during the development of hypertension, while in developed, stabilized and uncomplicated hypertension, systemic MMP-2 and MMP-9 inhibition may not be desirable.

Abstract
Cardiac autonomic neuropathy (CAN) is a least diagnosed complication of diabetes. Inflammation and oxidative stress play a crucial role in the pathophysiology of cardiomyopathy and neuropathy. Escin has anti-inflammatory activity and antioxidant activity. Hence, the present study was designed to evaluate the effect of escin in the management of CAN. Diabetes was induced in Sprague Dawley rats with streptozotocin (STZ). Diabetic animals were randomized in different groups after 6 weeks. Animals in the diabetic control group received no treatment, while animals in other groups received escin at dose 5, 10, and 20 mg/kg for 4 weeks. One group was kept as normal control. Various parameters like basic hemodynamic parameters, heart rate variability (HRV), oxidative stress parameters, and matrix metalloproteinase 9 (MMP-9) were assessed at the end of study. Escin significantly normalized hemodynamic parameters and HRV as compared to diabetic animals. Escin significantly reduced the malondialdehyde level and significantly increased reduced glutathione, catalase and superoxide dismutase levels in diabetic animals. Escin treatment significantly reduced plasma MMP-9 level in diabetic rats. The improvement in the studied parameters was found mainly with administration of higher doses of escin (10 and 20 mg/kg). The escin treatment mitigates CAN in diabetic rats. The results of study indicate that escin can be useful option for management of CAN.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a rare connective tissue disease associated with rapid evolving interstitial lung disease (SSc-ILD), driving its mortality. Specific biomarkers associated with the evolution of the lung disease are highly needed. We aimed to identify specific biomarkers of SSc-ILD to predict the evolution of the disease. Nucleosomes are stable DNA/protein complexes that are shed into the blood stream making them ideal candidates for biomarkers. METHODS We studied circulating cell-free nucleosomes (cf-nucleosomes) in SSc patients, 31 with ILD (SSc-ILD) and 67 without ILD. We analyzed plasma levels for cf-nucleosomes and investigated whether global circulating nucleosome levels in association with or without other biomarkers of interest for systemic sclerosis or lung fibrosis (e.g., serum growth factors: IGFBP-1 and the MMP enzyme: MMP-9), could be suitable potential biomarkers for the correct identification of SSc-ILD disease. RESULTS We found that H3.1 nucleosome levels were significantly higher in patients with SSc-ILD compared SSc patients without ILD (p < 0.05) and levels of MMP-9 were significantly increased in patients with SSc-ILD compared to SSc patients without ILD (p < 0.05). Conversely, IGFBP-1 was significantly reduced in patients with SSc-ILD compared to SSc without ILD (p < 0.001). The combination of cf-nucleosomes H3.1 coupled to MMP-9 and IGFBP-1 increased the sensitivity for the differential detection of SSc-ILD. High levels of accuracy were reached with this combined model: its performances are strong with 68.4% of positive predictive value and 77.2% of negative predictive value for 90% of specificity. With our model, we identified a significant negative correlation with FVC % pred (r = -0.22) and TLC % pred (r = -0.31). The value of our model at T1 (baseline) has a predictive power over the Rodnan score at T2 (after 6-18 months), showed by a significant linear regression with R2 = 19% (p = 0.013). We identified in the sole group of SSc-ILD patients a significant linear regression with a R2 = 54.4% with the variation of DLCO between T1 and T2 (p < 0.05). CONCLUSION In our study, we identified a new blood-based model with nucleosomic biomarker in order to diagnose SSc-ILD in a SSc cohort. This model is correlated with TLC and FVC at baseline and predictive of the skin evolution and the DLCO. Further longitudinal exploration studies should be performed in order to evaluate the potential of such diagnostic and predictive model.

Abstract
This study was designed to investigate the expressions and roles of MMP-9 and HMGB1 in peripheral blood of patients with epilepsy and their relationship with the cognitive function and to explore factors affecting the prognosis of epilepsy patients. A total of 127 patients with epilepsy were collected in the study group and 120 healthy subjects receiving a physical examination at the same time were collected in the control group. The MMP-9 and HMGB1 expressions and their diagnostic value for epilepsy were compared between the two groups. The relationship between MMP-9 and HMGB1 expression levels and the clinical-pathological features and the Mini-mental State Evaluation Scale (MMSE) of patients from the study group were also analyzed. The serum levels of MMP-9 and HMGB1 in the study group were significantly higher than those in the control group (P< 0.001), and were greatly decreased after the treatment (P<0.001). The ROC curve showed that MMP-9 and HMGB1 combined detection had a good diagnostic efficiency for epilepsy. MMP-9 was much related to the type and disease duration of epilepsy (P< 0.05). HMGB1 was significantly associated with disease duration, seizure, and previous treatment history of epilepsy (P< 0.050). According to the Pearson correlation coefficient analysis, the expressions of MMP-9 and HMGB1 were negatively correlated with MMSE scores of the study group (P< 0.001). Logistic regression analysis showed that the duration of disease, seizures, MMP-9, and HMGB1 were independent risk factors for the prognosis of epilepsy. The expression levels of MMP-9 and HMGB1 in peripheral blood of patients with epilepsy are significantly increased, and negatively correlated with neurological function scores. They have potential involvement in the occurrence and development of epilepsy, which makes them significant for the diagnosis and treatment of epilepsy in the future.

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
BACKGROUND To explore the role of resistin (RE) on deep vein thrombosis (DVT) and the molecular mechanism. METHODS ELISA assay was used to determine the concentration of RE, MMP-2, MMP-9, and PAI-1 in serum of DVT patients and controls. Rats were randomly divided into 4 groups: control, DVT, DVT + RE, and DVT + RE + SB203580 group. HE staining was used to observe the intravascular situation and thrombosis in the 4 groups. The relative mRNA levels and protein expression of RE, MMP-2, MMP-9, and PAI-1 in the 4 groups were determined by RT-PCR and western blotting. RESULTS The concentration of RE, MMP-2, MMP-9, and PAI-1 in serum from DVT patients was significantly higher than that in controls. RE promoted thrombosis in rats with DVT, while SB203580 inhibited the promotion of RE on thrombosis. RE up-regulated the expression of MMP-2, MMP-9, and PAI-1 in DVT rat models. Introduction of SB203580 inhibited the expression of RE, which then abolished the up-regulation role of RE on the expression of MMP-2, MMP-9, and PAI-1. CONCLUSIONS RE promoted thrombosis in DVT rat models by increasing the expression of MMP-2, MMP-9, and PAI-1.

Abstract
To evaluate the effect of coal-burning arsenic (As) exposure on lung function and the potential underlying mechanisms, a total of 217 As-exposed subjects and 75 reference subjects were recruited into this study. Hair arsenic (H-As), pulmonary function tests, and serum inflammatory markers CC16, SP-A, MMP-9, and TIMP-1 were evaluated. Residents from As-exposed areas showed higher H-As concentrations (median 0.25 μg/g) than subjects from the reference area (median 0.14 μg/g). Large reductions in lung function parameters were noted in the As-exposed group. A significant negative correlation was observed between H-As concentrations and lung function. Specifically, monotonic negative dose-response relationships were observed between H-As and FEV1(%), FEV1/FVC (%) and FEF75 (%) (all P < 0.05), while the associations between H-As and FVC (%), FEF25 (%), and FEF50 (%) were nonlinear (P for nonlinearity = 0.03, 0.001, 0.01, respectively). In addition, there was a direct positive relationship between H-As and the inflammatory response. Alterations in inflammatory biomarkers (CC16, SP-A, MMP-9, and MMP-9/TIMP-1) were significantly associated with As-induced lung function impairment. Thus, this population-based study revealed that As exposure has significant toxic effects on lung function and increased inflammation may occur during this toxic process. We provide scientific evidence for an As-induced alteration in inflammatory biomarkers and pulmonary damage in an As-exposed population. The results of this study can inform risk assessment and risk control processes in relation to human As exposure in coal-burning arsenicosis areas.

Matrix metalloproteinase 9 (MMP9) level and MMP9 -1562C>T in patients with obstructive sleep apnea: a systematic review and meta-analysis of case-control studies. Sleep Med 2020; 67:110-119. [PMID: 31918116 DOI: 10.1016/j.sleep.2019.11.1247] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [What about the content of this article?

Abstract
BACKGROUND The peripheral level of matrix metalloproteinase (MMP)-9 and polymorphism of MMP9 -1562C>T in patients with obstructive sleep apnea (OSA) remains controversial. Therefore, the aims of this systemic review and meta-analysis are to assess the MMP9 level in OSA patients and identify the relationship between MMP9 -1562C>T and OSA susceptibility. METHODS This systematic review was performed following the PRISMA guideline. We searched for studies in major databases, identifying those indexed from inception to July 3, 2019 which related to MMP9 level, MMP9 -1562C>T and OSA. The pooled standardized mean differences (SMDs) and 95% confidence interval (CI) of MMP9 levels were calculated. In addition, the relationship between MMP9 -1562C>T and OSA susceptibility was assessed by three genetic models. The heterogeneity analysis and calculation of the pooled odds ratio (OR) were also performed, followed by quality assessment using the Newcastle-Ottawa Scale (NOS). RESULTS In sum, our review included 15 eligible studies regarding MMP9 level and three regarding MMP9 -1562C>T. The pooled results showed that peripheral level of MMP9 was increased in OSA patients (SMD = 1.37; 95% CI = 1.15-1.59). Furthermore, significant difference of MMP9 level can be found between severe and mild-to-moderate OSA patients (SMD = 28.17; 95% CI = 4.23-52.11) or between moderate-severe and mild OSA (SMD = 36.62; 95% CI = 12.19-61.04). However, no relationship was observed between MMP9 -1562C>T and OSA susceptibility in three genetic models (Homozygote model, OR = 1.37; 95% CI = 0.87-2.18); (Recessive model, OR = 1.42; 95% CI = 0.83-2.42); (Allele model, OR = 1.07; 95% CI = 0.96-1.18). CONCLUSIONS This systemic review and meta-analysis indicated that the level of MMP9 was increased in patients with OSA and this increase is relevant to OSA severity. Moreover, the relationship between MMP9 -1562 C>T and OSA susceptibility has currently not been proven by current merging values. Further analyses with larger sample size are required to verify these associations.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) are involved in vascular wall degradation, and drugs able to modulate MMP activity can be used to prevent or treat aneurysmal disease. In this study, we evaluated the effects of statins on MMP-2, MMP-9, and neutrophil gelatinase-associated lipocalin (NGAL) in both plasma and tissue in patients with aneurysmal disease. METHODS We performed a prospective, single-blind, multicenter, control group clinical drug trial on 184 patients of both sexes >18 years old with a diagnosis of arterial aneurysmal disease. Enrolled patients were divided into two groups: Group I under statin treatment and Group II not taking statins. In addition, 122 patients without aneurysmal disease and under statin treatment were enrolled as a control group (Group III). The expression of MMPs and NGAL in plasma was evaluated using ELISA, while their expression in endothelial tissues was evaluated using Western blot. RESULTS The ELISA test revealed greater plasma levels (p < 0.01) of MMPs and NGAL in Groups I and II vs. Group III. Western blot analysis showed higher expression (p < 0.01) of MMPs and NGAL in Group II vs. Group I, and this increase was significantly higher (p < 0.01) in patients treated with low potency statins compared to high potency ones. CONCLUSIONS MMPs and NGAL seem to play a major role in the development of aneurysms, and their modulation by statins suggests that these drugs could be used to prevent arterial aneurysmal disease.

Abstract
We study the effect of an enriched cholesterol-methionine diet administered to females on the cardiac tissue remodelling of the offspring during two successive pregnancies. Two groups are constituted, standard diet (SD) group fed a standard diet and CD group fed a combined diet (standard + cholesterol 1%-methionine 0.25%). The diet is administered during 80 days. The results show changes in serum and cardiac parameters of CD newborn, with the involvement of phospholipids (PLs) (phosphatidylethanolamine (PE) and phosphatidylcholine (PC), variations in malondialdehyde (MDA), conjugated diene (CD), and vitamin C [VIT-C] rates). Under the CD effect, serum matrix metalloproteinase (MMP)-2, pro-MMP-9, and MMP-9 activities change. As to cardiac MMP-2 activity, a rise is noticed in the second pregnancy. Histological analysis reveals constricted blood capillaries, collagen fibre deposits, and lipid accumulation in the CD newborn heart. Our study shows the amplified effect of the maternal cholesterol-methionine diet in the second pregnancy on newborn cardiac disorders (matrix remodelling, oxidative stress, and lipid accumulation).

Abstract
Arsenic exposure in adults has been associated with increased serum matrix metalloproteinase-9 (MMP-9), a biomarker which is associated with chronic respiratory disease, lung inflammation, cardiovascular disease and cancer. The objective of this study was to evaluate the association between serum MMP-9 levels in children, urinary arsenic, arsenic chronic daily intake (CDI) and arsenic exposure from playground dust. This cross-sectional study examined 127 children from five elementary schools, in Hermosillo, Sonora, Mexico. Arsenic was analyzed in the dust using a portable X-ray fluorescence (XRF) analyzer. Total urinary arsenic was determined by inductively coupled plasma/optical emission spectrometry. Serum was analyzed for MMP-9 using ELISA. Arsenic levels in playground dust averaged 16.9 ± 4.6 mg/kg. Urinary arsenic averaged 34.9 ± 17.1 µg/L. Arsenic concentration in playground dust was positively associated with serum MMP-9 levels in crude analyses and after adjustment (P < 0.01), MMP-9 and CDI were positively associated only after adjustment (P < 0.01), and no association was found between MMP-9 and urinary arsenic. In conclusion, our study showed an association in children between serum MMP-9 levels and playground dust arsenic concentrations. Therefore, exposure to arsenic in dust where children spend significant time may manifest toxic effects.

Abstract
BACKGROUND The current study aims to investigate the expression of antisense noncoding RNA in the INK4 locus (ANRIL) in serum of patients with ischemic stroke and its correlation with high-sensitivity C-reactive protein (hs-CRP) and matrix metalloproteinase-9 (MMP-9). METHODS Real time PCR analysis was carried out to evaluate the level of ANRIL. The levels of hs-CRP and MMP-9 were evaluated using ELISA. ROC analysis was carried out to evaluate the diagnostic value of ANRIL, hs-CRP and MMP-9. Pearson's correlation analysis was carried out to evaluate the expression of ANRIL in serum of hs-CRP and MMP-9. RESULTS Our data showed that the expression levels of ANRIL, hs-CRP, and MMP-9 in serum of the patients were significantly higher than those of the control group (p < 0.05). Pearson's correlation analysis showed that there was a positive correlation between the expression of ANRIL and hs-CRP and MMP-9. Meanwhile, serum levels of ANRIL, hs-CRP, and MMP-9 in patients with severe neurological deficits were significantly higher than those in patients with moderate and mild neurological deficits (p < 0.05). Moreover, the expression levels of ANRIL, hs-CRP, and MMP-9 in serum of patients with different degrees of neurological impairment have different correlations. More importantly, ROC analysis demonstrated that the combined use of ANRIL, hs-CRP, and MMP-9 demonstrated higher diagnostic value for stroke patients. CONCLUSIONS Serum ANRIL may be used as a molecular marker in the diagnosis of ischemic stroke and may play an important role in the pathogenesis and development of ischemic stroke in cooperation with hs-CRP and MMP-9.

Abstract
Neuroinflammation contributes to the occurrence and development of epilepsy. However, several inflammatory factors that are important for facilitating the diagnosis to reduce or prevent seizures need to be further studied. This study is aimed to explore serum levels of matrix metalloproteinase-9 (MMP-9), interleukin-6 (IL-6), hypersensitive C-reactive protein (hs-CRP), and homocysteine (HCY) in epilepsy patients and the relationship of them with epilepsy. Epilepsy patients (n = 101) in the Second Xiangya Hospital from January 2017 to August 2018 were allocated to the epilepsy groups, which were divided into idiopathic epilepsy group (n = 43) and symptomatic epilepsy group (n = 58) according to the pathogeny. Healthy individuals (n = 50) were allocated to the control group. The concentrations of serum MMP-9, IL-6, hs-CRP, and HCY in all samples were detected by enzyme-linked immunosorbent assay, chemiluminescence method, latex-enhanced immunoturbidimetry, and enzyme circulation method. The levels of serum MMP-9, IL-6, hs-CRP, and HCY in epilepsy patients were higher than those in the control group (P < 0.05, P < 0.01, P < 0.01, and P < 0.01, respectively). The levels of serum MMP-9, IL-6, hs-CRP, and HCY in the symptomatic epilepsy group were higher than those in the control group (P < 0.01 or P < 0.05, respectively). The levels of serum MMP-9, IL-6, and hs-CRP in idiopathic epilepsy patients were higher than those in the control group (P < 0.01 or P < 0.05, respectively). The serum HCY level in the idiopathic epilepsy group was lower than that in the symptomatic epilepsy group (P < 0.01). MMP-9, IL-6, hs-CRP, and HCY may be recommended as the state biomarker to distinguish etiology of epilepsy. We hope our study could provide help in some ways for clinical diagnosis and treatment.

Abstract
The purpose of this study was to analyze changes in the levels of matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1), and transforming growth factor-β1 (TGF-β1) in response to strength recovery after eccentric exercise in humans. In this study, 16 healthy males participated and were divided into a faster recovery (FR) group (n = 8, >80% of baseline) and a slower recovery (SR) group (n = 8, <40% of baseline) on the basis of their recovery of maximal isometric strength (MIS) 96 h after eccentric exercise. For both groups, measurements were taken of muscle soreness, creatine kinase (CK) activity, and MMP-9, TIMP-1, and TGF-β1 levels during the 24- to 96-h period after eccentric muscle contraction of their non-dominant elbow flexor. Muscle soreness (p < 0.001), CK activity (p < 0.01), and TGF-β1 level (p < 0.01) were significantly lower in the FR group compared with SR group, whereas no significant differences in MMP-9 and TIMP-1 levels were found between the two groups (p > 0.05). These results suggest that scar tissue formation caused by the pro-fibrotic activity of growth factors such as TGF-β1 is a potential cause of delay in strength recovery after exercise-induced muscle injury.

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
Results of previous epidemiology studies on BPA exposure and endometriosis (EMs) risk were inconsistent, and were limited by inappropriate control selection, incorrect BPA detection method, and the generalization of different subtypes of EMs. Upregulated matrix metalloproteinase (MMP) 2 and MMP9 are involved in the development of EMs. We conducted a case-control study among 120 EMs patients and 100 healthy women to evaluate the relationships between BPA exposure and MMP2, MMP9 expressions, and the risk of EMs subtypes. Besides, we used human endometrial stromal cell lines (HESCs) to investigate the underlying mechanisms. Creatinine-adjusted urinary BPA concentrations were positively correlated with serum MMP2, MMP9 levels, and the risk of peritoneal EMs (third vs lowest quartile: OR 4.92, 95% CI 1.47, 16.50; fourth versus lowest quartile: OR 3.70, 95% CI 1.07, 12.74, Ptrend = 0.030). The risk of peritoneal EMs increased approximately tenfold when creatinine-adjusted urinary BPA concentration was 2 μg/g. In vitro study found that BPA exposure increased MMP2, MMP9 expressions in a dose-dependent manner. The effects of BPA on HESCs could be blocked by G protein-coupled estrogen receptor (GPER) inhibitor or mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) inhibitor. This study provides evidence that BPA exposure promotes peritoneal EMs, and raises a concern about the potential toxicity of BPA on the female reproductive system.

Abstract
BACKGROUND AND AIMS The purpose of this study was to investigate whether an intervention with physical activity (PA) would promote positive effects on the angiogenic factors, mobilization, and functionality of circulating endothelial progenitor cells (EPCs) in children with low birth weight (LBW). METHODS AND RESULTS Thirty-five children participated in a 10-week PA program (intensity: 75-85% of heart rate reserve, frequency: four times/week, and duration: 45 min). Before and after the PA program, we evaluated anthropometric parameters, blood pressure levels, biochemical profile, number of EPCs, number of EPC colony forming units, and plasma levels of vascular endothelial growth factor-A (VEGF-A), nitric oxide (NO), and matrix metalloproteinases (MMPs) 2 and 9. We found a significant main effect of the PA program on waist circumference (ηp2 = 0.489), cardiorespiratory fitness (ηp2 = 0.463), and MMP-9 (ηp2 = 0.582). Birth weight or the PA program produced significant independent effects on systolic blood pressure (birth weight: ηp2 = 0.431; PA program: ηp2 = 0.615) and EPC colony forming units (birth weight: ηp2 = 0.541; PA program: ηp2 = 0.698) with no significant interactions. The combination of birth weight and the PA program produced a significant interaction effect on the number of circulating EPCs (ηp2 = 0.123), NO (ηp2 = 0.258), and VEGF-A (ηp2 = 0.175). The variation in the number of EPCs from baseline to 10 weeks of the PA program correlated positively with the change in NO (P = 0.002) and VEGF-A (P = 0.004). CONCLUSIONS A 10-week PA program attenuates the adverse effect of LBW on the number and functionality of EPCs; this effect occurs through an improvement in circulating levels of NO and VEGF-A.

Abstract
As myocardial fibrosis might be an important contributor to the association of diabetes mellitus with left ventricular (LV) dysfunction and chronic heart failure (HF), we investigated the profile of some proinflammatory, profibrotic biomarkers in patients with type 2 diabetes mellitus (T2DM) at various stages of the cardiovascular disease continuum from absence of clinic since and symptoms to HF with preserved (HFpEF) and midrange ejection fraction (HFmrEF). Material and Methods. Sixty-two patients with T2DM (age 60 [55; 61]), 20 patients without clinical manifestations of HF and 2 groups with clinical manifestations of stable HF, 29 patients with HFpEF, and 13 patients with HFmrEF, were included in the study. The control group consisted of 13 healthy subjects and normal BMI. All patients underwent transthoracic echocardiography, laboratory assessment of N-terminal fragment of the brain natriuretic peptide (Nt-proBNP), highly sensitive C-reactive protein (hsCRP), soluble suppression of tumorigenesis-2 (sST2), galectin-3, C-terminal propeptide of procollagen type I (PICP), N-terminal propeptide of procollagen type III (PIIINP), matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of matrix proteinase-1 (TIMP-1). Results. Patients with HFmrEF had higher values of LV volumetric parameters, indexed parameters of LV myocardial mass (LVMM), and higher concentrations of Nt-proBNP (all p < 0.05). The concentrations of galectin-3 were greater in patients with HFpEF and HFmrEF compared to patients without HF (p = 0.01 and p = 0.03, respectively). PICP and PICP/PIIINP ratio were greater in patients with HFmrEF compared to patients with HFpEF (p = 0.043 and p = 0.033, respectively). In patients with T2DM and HF, a relationship was found between galectin-3 and LVMM/body surface area (r = -0.58, p = 0.001), PIIINP, TIMP-1, and LV end-diastolic volume (r = -0.68 and p = 0.042 and r = 0.38 and p = 0.02, respectively). Conclusion. The dynamics at various stages of the cardiovascular disease continuum in the serum fibrosis markers may reflect an increase in fibrotic and decrease in antifibrotic processes already at the preclinical stage of HF. At the same time, the changes found in the circulating procollagen levels may indicate a shift in balance towards type I collagen synthesis in HFmrEF compared with HFpEF.

Abstract
The purpose was to investigate the efficacy and safety of Osimertinib in the treatment of advanced non-small cell lung cancer and to analyze its effects on the expression of serum matrix metalloproteinase-7 (MMP-7) and matrix metallo-proteinase-9 (MMP-9). Eighty patients were equally divided into observation and control group. The observation group was given Osimertinib combined with conventional chemotherapy and the other was treated with conventional chemotherapy alone. The short-term efficacy, the levels of serum MMP-7, MMP-9 and adverse reactions were compared. The effectiveness and clinical benefit rate of the observation group were 62.50% and 92.50% respectively, significantly higher than the control group. There was no significant difference in MMP-7 and MMP-9 before treatment however there was a significant difference after treatment, and the serum MMP-7 & MMP-9 levels showed a trend of increasing with decreasing efficacy. After treatment, comparing with control group, serum MMP-7 and MMP-9 levels were significantly lower, the Karnofsky score was significantly higher, and the improvement effect of the quality of life was statistically significant. Besides, the incidence of leukopenia, thrombocytopenia, anemia and gastrointestinal symptoms were significantly lower. In the treatment of patients with advanced non-small cell lung cancer, Osimertinib significantly reduced the expression of serum MMP-7, MMP-9, improved the clinical benefit and quality of life of patients. The clinical efficacy was significant with a high safety.

Abstract
Objective To determine whether the matrix metalloproteinases-2 and -9 plasma levels were associated with intensive care unit mortality in patients who suffered severe traumatic brain injury, despite the presence of extracerebral injuries. Methods This prospective cohort enrolled 39 male patients who suffered severe traumatic brain injury (Glasgow coma scale: 3 - 8 at hospital admission). The plasma matrix metalloproteinase -2 and matix metalloproteinase -9 levels were determined by ELISA at the time of intensive care unit admission. Results Severe traumatic brain injury was associated with a 46% intensive care unit mortality rate. Higher plasma matrix metalloproteinase -9 concentrations were associated with mortality: 147.94 ± 18.00ng/mL for survivors and 224.23 ± 23.86ng/mL for nonsurvivors (mean ± standard error of the mean, p = 0.022). In contrast, there was no significant association between matrix metalloproteinase -2 levels and intensive care unit mortality: 315.68 ± 22.90ng/mL for survivors and 336.55 ± 24.29ng/mL for nonsurvivors (p = 0.499). Additionally, there were no significant associations between matrix metalloproteinase -2 (p = 0.711) and matrix metalloproteinase -9 (p = 0.092) levels and the presence of associated lesions. Conclusion Increased plasma matrix metalloproteinase -9 levels were associated with intensive care unit mortality following severe traumatic brain injury, regardless of the presence of extracerebral injuries. Conversely, in this same context, plasma matrix metalloproteinase -2 levels were not associated with short-term fatal outcome prediction.

Abstract
Matrix metallopeptidase 2 (MMP-2) and matrix metallopeptidase 9 (MMP-9) are involved in the breakdown of extracellular matrix in normal physiological processes as well as in disease processes, such as cancer metastasis. We conducted this work to study the role of MMP-2 and MMP-9 in breast cancer by measuring their plasma concentrations before and after surgery. Also, to examine if their levels can reflect the stage of disease and prognosis. Forty-eight breast cancer patients and 13 patients with benign breast diseases were included in the study. MMP-2 and MMP-9 levels were measured by ELISA and semi-quantitative real-time PCR. MMP-2 and MMP-9 levels in plasma were determined by ELISA immediately before surgery and during 6 to 12 months after curative surgery. We observed a significant increase in the level of MMP-9 mRNA expression in breast cancer patients in comparison to their normal breast tissues and to tissues of benign breast disease. In all TNM tumor stages, the plasma levels of MMP-2 and MMP-9 were increased significantly before curative surgery in the studied patients with breast carcinoma and decreased significantly after surgery. Both MMP-2 and MMP-9 may be used as a possible marker for follow-up or as a marker that reflects the response of the disease to treatment.

Abstract
Numerous studies have demonstrated that cancer-related matrix metalloproteinase-9 (MMP-9) is an ideal biomarker for cancer diagnosis. However, most MMP-9 detection methods are expensive and time-consuming, and more convenient and specific MMP-9 detection methods are needed both clinically and in research. In the present study, peptide-linked polymer dots were assembled onto a graphene oxide surface to construct a graphene oxide-peptide-polymer dot (GO-Pep-Pdot) nanocomplex for sensitive, rapid, and accurate detection of MMP-9. In the absence of MMP-9, the nanocomplex was in an "off" state, whereas in the presence of MMP-9, the nanocomplex was turned "on", resulting in the emission of a fluorescence signal that is linearly correlated with the MMP-9 concentration. The limit of detection of the nanocomplex was 3.75 ng mL-1, lower than most methods. This method was successfully verified by detecting MMP-9 in clinical serum samples of prostate cancer. The results suggest that this protease nanocomplex is generic and can be adopted to respond to other proteases by selecting specific peptides with suitable cleavage sites in clinics.
