| 1 | Proteolytic-antiproteolytic balance and its regulation in carcinogenesis显示文摘Cancer development is essentially a tissue remodeling process in which normal tissue is substituted with cancer tissue. A crucial role in this process is attributed toproteolytic degradation of the extracellular matrix (ECM).Degradation of ECM is initiated by proteases, secreted by different cell types, participating in tumor cell invasion and increased expression or activity of every known class of proteases (metallo-, serine-, aspartyl-, and cysteine)has been linked to malignancy and invasion of tumor cells.Proteolytic enzymes can act directly by degrading ECM or indirectly by activating other proteases, which then degrade the ECM. They act in a determined order, resulting from the order of their activation. When proteases exert their action on other proteases, the end result is a cascade leading to proteolysis. Presumable order of events in this complicated cascade is that aspartyl protease (cathepsin D) activates cysteine proteases (e.g. cathepsin B) that can activate pro-uPA. Then active uPA can convert plasminogen into plasmin. Cathepsin B as well as plasmin are capable of degrading several components of tumor stroma and may activate zymogens of matrix metalloproteinases, the main family of ECM degrading proteases. The activities of these proteases are regulated by a complex array of activators,inhibitors and cellular receptors. Tn physiological conditions the balance exists between proteases and their inhibitors.Proteolytic-antiproteolytic balance may be of major significance in the cancer development. One of the reasons for such a situation is enhanced generation of free radicals observed in many pathological states. Free radicals react with main cellular components like proteins and lipids and in this way modify proteolytic-antiproteolytic balance and enable penetration damaging cellular membrane. All these lead to enhancement of proteolysis and destruction of ECM proteins and in consequence to invasion and metastasis. | Elzbieta Skrzydlewska Mariola Sulkowska Mariusz Koda Stanislaw Sulkowski | 2005 | World Journal of Gastroenterology2005，11，9： | 14 |
| 2 | Lipid peroxidation and antioxidant status in colorectal cancer显示文摘AIM: Reactive oxygen species (ROS) can induce carcinogenesis via DNA injury. Both enzymatic and non-enzymatic parameters participate in cell protection against harmful influence of oxidative stress. The aim of the present study was to assess the levels of final lipid peroxidation products like malondialdehyde (MDA) and 4-hydroxy-2-nonenal (4-HNE) in primary colorectal cancer. Moreover, we analysed the activity of main antioxidative enzymes, superoxide dismutase (Cu, Zn-SOD),catalase (CAT), glutathione peroxidase (GSH-Px) and glutathione reductase (GSSRG-R) and the level of nonenzymatic antioxidants (glutathione, vitamins C and E).METHODS: Investigations were conducted in 81 primary colorectal cancers. As a control, the same amount of sample was collected from macroscopically unchanged colon regions of the most distant location to the cancer.Homogenisation of specimens provided 10% homogenates for our evaluations. Activity of antioxidant enzymes and level of glutathione were determined by spectrophotometry.HPLC revealed levels of vitamins C and E and served as a method to detect terminal products of lipid peroxidation in colorectal cancer.RESULTS: Our studies demonstrated a statistically significant increase in the level of lipid peroxidation products (MDA-Adc.muc.-2.65±0.48 nmol/g, Adc. G3-2.15±0.44 nmol/g, clinical Ⅳ stage 4.04±0.47 nmol/g, P<0.001 and 4-HNE-Adc.muc.-0.44±0.07 nmol/g, Adc. G3-0.44±0.10 nmol/g, clinical Ⅳstage 0.52±0.11 nmol/g, P<0.001) as well as increase of Cu,Zn-SOD (Adc.muc.-363±72 U/g, Adc. G3-318±48 U/g,clinical Ⅳ stage 421±58 U/g, P<0.001), GSH-Px (Adc.muc.-2143±623 U/g, Adc. G3-2005±591 U/g, clinical Ⅳ stage 2467±368 U/g, P<0.001) and GSSG-R (Adc. muc.-880±194 U/g,Adc. G3-795±228 U/g, dinical Ⅳ stage 951±243 U/g, P<0.001)in primary tumour comparison with normal colon (MDA1.39±0.15 nmol/g, HNE-0.29±0.03 nmol/g, Cu, Zn-SOD-117±25 U/g, GSH-Px-1723±189 U/g, GSSG-R-625±112 U/g)especially in mucinous and G3-grade adenocarcinomas as well as clinical Ⅳ stage of colorectal cancer. We also observed a decrease of CAT activity (Adc.muc. -40±14 U/g,clinical Ⅳ stage 33±18 U/g vs84±17 U/g, P<0.001) as well as a decreased level of reduced glutathione (clinical Ⅳ stage 150±48 nmol/g vs 167±15 nmol/g, P<0.05) and vitamins C and E (vit. C-clinical Ⅳ stage 325±92 nmol/g vs 513±64 nmol/g, P<0.001; vit. E-clinical Ⅳ stage 13.3±10.3nmol/g vs37.5±5.2 nmol/g).CONCLUSION: Colorectal carcinogenesis is associated with serious oxidative stress and confirms that gradual advancement of oxidative-antioxidative disorders is followed by progression of colorectal cancer. | Elzbieta Skrzydlewska Stanislaw Sulkowski Mariusz Koda Bogdan Zalewski Luiza Kanczuga-Koda Mariola Sulkowska | 2005 | World Journal of Gastroenterology2005，11，3： | 12 |
| 3 | Carbon/carbon supercapacitors显示文摘Supercapacitors, or electrochemical capacitors, are a power storage system applied for harvesting energy and delivering pulses during short periods of time. The commercially available technology is based on charging an electrical double-layer (EDL), and using high surface area carbon electrodes in an organic electrolyte. This review first presents the state-of-the-art on EDL capacitors, with the objective to better understand their operating principles and to improve their performance. In particular, it is shown that capacitance might be enhanced for carbons having subnanometric pores where ions of the electrolyte are distorted and partly desolvated. Then, strategies for using environment friendly aqueous electrolytes are presented. In this case, the capacitance can be enhanced through pseudo-faradaic contributions involving i) surface functional groups on carbons, ii) hydrogen electrosorption, and iii) redox reactions at the electrode/electrolyte interface. The most promising system is based on the use of aqueous alkali sulfate as electrolyte allowing voltages as high as 2 V to be reached, due to the high overpotential for di-hydrogen evolution at the negative electrode. | Elzbieta Frackowiak Qamar Abbas Franois Bguin | 2013 | Journal of Energy Chemistry2013，22，2： | 10 |

| 5 | Insulin resistance,adipokine profile and hepatic expression of SOCS-3 gene in chronic hepatitis C显示文摘AIM:to analyze adipokine concentrations,insulin resistance and hepatic expression of suppressor of cytokine signaling 3(SOCS-3)in patients with chronic hepatitis C genotype 1 with normal body weight,glucose and lipid profile.METHODS:The study group consisted of 31 patients with chronic hepatitis C and 9 healthy subjects.Total levels of adiponectin,leptin,resistin,visfatin,omentin,osteopontin and insulin were measured using an ELISA kit.The hepatic expression of SOCS-3 was determined by the use of the reverse transcription polymerase chain reaction method.RESULTS:Homeostasis model assessment for insulin resistance(HOMA-IR)values were significantly higher in hepatitis C virus(HCV)infected patients without metabolic disorders compared to healthy controls(2.24 vs 0.59,P=0.0003).Hepatic steatosis was observed in 32.2%of patients with HCV infection and was found in patients with increased HOMA-IR index(2.81 vs1.99,P=0.05)and reduced adiponectin level(5.96vs 8.37,P=0.04).Inflammatory activity(G≥2)was related to increased osteopontin concentration(34.04vs 23.35,P=0.03).Advanced liver fibrosis(S≥2)was associated with increased levels of omentin and osteopontin(436.94 vs 360.09,P=0.03 and 32.84 vs20.29,P=0.03)and reduced resistin concentration(1.40 vs 1.74,P=0.047).No correlations were reported between adipokine profile,HOMA-IR values and hepatic expression of the SOCS-3 gene.CONCLUSION:We speculated that no relationship between adipokines and HOMA-IR values may indicate that HCV can induce insulin resistance itself.Some adipokines appear to be biochemical markers of steatosis,inflammation and fibrosis in patients with chronic HCV infection. | Kamila Wójcik Elzbieta Jabonowska Aleksandra Omulecka Anna Piekarska | 2014 | World Journal of Gastroenterology2014，20，30： | 8 |
| 6 | Intestinal epithelium, intraepithelial lymphocytes and the gut microbiota-Key players in the pathogenesis of celiac disease显示文摘Celiac disease(CD) is a chronic immune-mediated disorder triggered by the ingestion of gluten in genetically predisposed individuals. Before activating the immune system, gluten peptides are transferred by the epithelial barrier to the mucosal lamina propria, where they are deamidated by intestinal tissue transglutaminase 2. As a result, they strongly bind to human leucocyte antigens(HLAs), especially HLA-DQ2 and HLA-DQ8, expressed on antigen-presenting cells. This induces an inflammatory response, which results in small bowel enteropathy. Although gluten is the main external trigger activating both innate and adaptive(specific) immunity, its presence in the intestinal lumen does not fully explain CD pathogenesis. It has been hypothesized that an early disruption of the gut barrier in genetically susceptible individuals, which would result in an increased intestinal permeability, could precede the onset of gluten-induced immune events. The intestinal barrier is a complex functional structure, whose functioning is dependent on intestinal microbiotahomeostasis, epithelial layer integrity, and the gutassociated lymphoid tissue with its intraepithelial lymphocytes(IELs). The aim of this paper was to review the current literature and summarize the role of the gut microbiota, epithelial cells and their intercellular junctions, and IELs in CD development. | Bozena Cukrowska Agnieszka Sowińska Joanna Beata Bierla Elzbieta Czarnowska Anna Rybak Urszula Grzybowska-Chlebowczyk | 2017 | World Journal of Gastroenterology2017，23，42： | 7 |
| 7 | Evaluation of serum catnepsin B and D in relation to diniGopatnological staging of colorectal cancer显示文摘AIM: Proteolytic degradation of the extracellular matrix facilitates cancer invasion and promotes metastasis. The study aims at evaluation of preoperative and postoperative serum cathepsins B and D levels in correlation with selected anatomoclinical features of colorectal cancer.METHODS: Blood samples were collected from 63colorectal cancer patients before curative operation of the tumor 10 d later. Blood that was obtained from 20healthy volunteers, served as a control. The activity of cathepsin B was measured with Bz-DL-arginine-pNA as a substrate at pH 6.0, while cathepsin D activity was determined with urea-denatured hemoglobin (pH 4.0).RESULTS: The preoperative and postoperative activities of cathepsin B were significantly (P<0.00001) lower in serum of colorectal cancer patients than in control group.However, postoperative values of this protease were significantly increased in comparison with preoperative ones (P = 0.031). Activity of cathepsin D appeared to be significantly higher in colorectal cancer sera (P<0.00001)compared with controls. No statistically significant differences between preoperative and postoperative activity of cathepsin D were noted (P = 0.09). We revealed a strong linkage of cathepsins' levels with lymph node status and pT stage of colorectal cancer.CONCLUSION: Blood serum activities of cathepsin B and D depend on the time of sampling, tumor size and lymph node involvement. Significantly, increased activity of cathepsin D could indicate a malignant condition of the large intestine. In our work, the serum postoperative decrease of cathepsin B activity appears as an obvious concomitant of local lymph node metastasis-the wellknown clinicopathological feature of poor prognosis. | Elzbieta Skrzydlewska Mariola Sulkowska Andrzej Wincewicz Mariusz Koda Stanislaw Sulkowski | 2005 | World Journal of Gastroenterology2005，11，27： | 6 |
| 8 | Ultrastructure of oval cells in children with chronic hepatitis B,with special emphasis on the stage of liver fibrosis:The first pediatric study显示文摘AIM:To investigate the ultrastructure of oval cells in children with chronic hepatitis B,with special emphasis on their location in areas of collagen fibroplasia. METHODS:Morphological investigations were conducted on biopsy material obtained from 40 children,aged 3-16 years with chronic hepatitis B. The stage of fibrosis was assessed histologically using the arbitrary semiquantitative numerical scoring system proposed by Ishak et al. The material for ultrastructural investigation was fixed in glutaraldehyde and paraformaldehyde and processed for transmission-electron microscopic analysis. RESULTS:Ultrastructural examination of biopsy specimens obtained from children with chronic hepatitis B showed the presence of two types of oval cells,the hepatic progenitor cells and intermediate hepatic-like cells. These cells were present in the parenchyma and were seen most commonly in areas of intense periportal fibrosis (at least stage 2 according to Ishak et al) and in the vicinity of the limiting plate of the lobule. The activated nonparenchymal hepatic cells,i.e. transformed hepatic stellate cells and Kupffer cells were seen in close proximity to the intermediate hepatic-like cells. CONCLUSION:We found a distinct relationship between the prevalence of oval cells (hepatic progenitor cells and intermediate hepatocyte-like cells) and fibrosis stage in pediatric patients with chronic hepatitis B. | Maria Elzbieta Sobaniec-Lotowska Joanna Maria Lotowska Dariusz Marek Lebensztejn | 2007 | World Journal of Gastroenterology2007，13，21： | 6 |

| 11 | Relationships between serum lipid,lipoprotein,triglyceride-rich lipoprotein,and high-density lipoprotein particle concentrations in post-renal transplant patients显示文摘Objective:Disturbances in lipid and lipoprotein profiles in patients after kidney transplantation (Tx) are still not understood. Methods:Serum levels of lipids,lipoprotein,triglyceride-rich lipoproteins (TRLs),and high-density lipoprotein (HDL) particles were determined,lipid and lipoprotein ratios were calculated,and their relationships in Tx patients with hypertriglyceridemia (HTG) and lower apolipoprotein AI (apoAI) concentration were examined. Serum lipid and lipoprotein levels were measured in 109 Tx patients and 89 healthy subjects. HDL particle levels were de-termined by enzyme-linked immunosorbent assay (ELISA). Results:Tx patients had disturbed concentration,com-position,and metabolism of TRLs and HDL particles. Multivariance analysis showed significant and positive correlation between HDL cholesterol/apoAI (HDL-C/apoAI) and HDL-C/HDL ratios,which indicates that both ratios could sensi-tively reflect changes in the HDL subclasses and their distribution into smaller size particles. In Tx patients,the de-creased HDL-C/apoAI ratio indicates that,along with the decreased apoAI concentration,the HDL-C level is de-creased. However,a low HDL-C/HDL ratio indicates that HDL particles in Tx patients transport lesser content of HDL-C but more triglyceride (TG) (high TG/HDL ratio),and thus are hypercatabolized and removed; therefore,con-centration of HDL particles in serum was decreased. Conclusion:The decrease of HDL-C/apoAI ratio seems to be a good marker of HDL subclass distribution into smaller size particles. | ElZbieta KIMAK Magdalena HALABI Iwona BARANOWICZ-GASZCZYK | 2010 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010，11，4： | 5 |
| 12 | Association between moderately oxidized low-density lipoprotein and high-density lipoprotein particle subclass distribution in hemodialyzed and post-renal transplant patients显示文摘Disturbances in the metabolism of lipoprotein profiles and oxidative stress in hemodialyzed(HD) and post-renal transplant(Tx) patients are proatherogenic,but elevated concentrations of plasma high-density lipoprotein(HDL) reduce the risk of cardiovascular disease.We investigated the concentrations of lipid,lipoprotein,HDL particle,oxidized low-density lipoprotein(ox-LDL) and anti-ox-LDL,and paraoxonase-1(PON-1) activity in HD(n=33) and Tx(n=71) patients who were non-smokers without active inflammatory disease,liver disease,diabetes,or malignancy.HD patients had moderate hypertriglyceridemia,normocholesterolemia,low HDL-C,apolipoprotein A-I(apoA-I) and HDL particle concentrations as well as PON-1 activity,and increased ox-LDL and anti-ox-LDL levels.Tx patients had hypertriglyceridemia,hypercholesterolemia,moderately decreased HDL-C and HDL particle concentrations and PON-1 activity,and moderately increased ox-LDL and anti-ox-LDL levels as compared to the reference,but ox-LDL and anti-ox-LDL levels and PON-1 activity were more disturbed in HD patients.However,in both patient groups,lipid and lipoprotein ratios(total cholesterol(TC)/HDL-C,LDL-C/HDL-C,triglyceride(TG)/HDL-C,HDL-C/non-HDL-C,apoA-I/apoB,HDL-C/apoA-I,TG/HDL) were atherogenic.The Spearman's rank coefficient test showed that the con-centration of ox-LDL correlated positively with HDL particle level(R=0.363,P=0.004),and negatively with TC(R=?0.306,P=0.012),LDL-C(R=?0.283,P=0.020),and non-HDL-C(R=?0.263,P=0.030) levels in Tx patients.Mul-tiple stepwise forward regression analysis in Tx patients demonstrated that ox-LDL concentration,as an independent variable,was associated significantly positively with HDL particle level.The results indicated that ox-LDL and de-creased PON-1 activity in Tx patients may give rise to more mildly-oxidized HDLs,which are less stable,easily un-dergo metabolic remodeling,generate a greater number of smaller pre-β-HDL particles,and thus accelerate reverse cholesterol transport,which may be beneficial for Tx patients.Further studies are necessary to confirm this. | Elzbieta KIMAK Magdalena HALABI Iwona BARANOWICZ-GASZCZYK Janusz SOLSKI Andrzej KSIAZEK | 2011 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2011，12，5： | 5 |
| 13 | Connexin 26 correlates with Bcl-xL and Bax proteins expression in colorectal cancer显示文摘AIM: To evaluate of Cx26 in correlation with Bcl-xL and Bax proteins in colorectal cancer.METHODS: Immunohistochemical staining using specific antibodies was performed to evaluate the protein expression of Cx26, Bax and Bcl-xL in 152 colorectal cancer samples and the correlations among studied proteins as well as the relationships between the expression of Cx26,Bax, Bcl-xL and clinicopathological features were analyzed.RESULTS: Both normal epithelial cells and carcinoma cells expressed Cx26, Bax and Bcl-xL, but Cx26 in cancer cells showed aberrant, mainly cytoplasmic staining. Expression of Cx26, Bax and Bcl-xL was observed in 55.9%, 55.5%and 72.4% of evaluated colorectal cancers respectively.We found the positive correlation between Cx26 and Bax expression (r = 0.561, P<0.0001), Cx26 and Bcl-xL (r = 0.409, P<0.0001) as well as between Bax and Bcl-xL (r = 0.486, P<0.0001). Association of Cx26, Bax and Bcl-xL expression with histological G2 grade of tumors was noted (P<0.005, P<0.001 and P<0.002 respectively).CONCLUSION: Cytoplasmic presence of Cx26 and its association with apoptotic markers could indicate a distinct role from physiological functions of Cx26 in cancer cells and it could suggest that connexins might be a target point for modulations of apoptosis with therapeutic implications. | Luiza Kanczuga-Koda Stanislaw Sulkowski Mariusz Koda Elzbieta Skrzydlewska Mariola Sulkowska | 2005 | World Journal of Gastroenterology2005，11，10： | 5 |
| 14 | Laparoscopy-assisted percutaneous endoscopic gastrostomy enables enteral nutrition even in patients with distorted anatomy显示文摘AIM:To analyzed whether laparoscopy-assisted percutaneous endoscopic gastrostomy(PEG)could be a valuable option for patients with complicated anatomy.METHODS:A retrospective analysis of twelve patients(seven females,five males;six children,six young adults;mean age 19.2 years)with cerebral palsy,spastic quadriparesis,severe kyphoscoliosis and interposed organs and who required enteral nutrition(EN)due to starvation was performed.For all patients,standard PEG placement was impossible due to distorted anatomy.All the patients qualified for the laparoscopyassisted PEG procedure.RESULTS:In all twelve patients,the laparoscopy-assisted PEG was successful,and EN was introduced four to six hours after the PEG placement.There were no complications in the perioperative period,either technical or metabolic.All the patients were discharged from the hospital and were then effectively fed using bolus methods.CONCLUSION:Laparoscopy-assisted PEG should become the method of choice for gastrostomy tube placement and subsequent EN if PEG placement cannot be performed safely. | Adam Hermanowicz Ewa Matuszczak Marta Komarowska Elzbieta Jarocka-Cyrta Jerzy Wojnar Wojciech Debek Konrad Matysiak Stanislaw Klek | 2013 | World Journal of Gastroenterology2013，19，43： | 5 |
| 15 | Soluble adhesion molecules ICAM-1,VCAM-1,P-selectin in children with Helicobacter pylori infection显示文摘AIM: To assess the sICAM-1, sVCAM-1, and sP-selectin levels in children withHelicobacter pylori(H pylori)infection and to evaluate their significance for the morphological changes found in gastric mucosa.METHODS: The study included 106 children: 59children (55.7%) with chronic gastritis and positive IgG against H pylori, 29 children (27.3%) after previous H pylori infection without the bacterium colonization but with positive IgG against H pylori, and 18 children (17%) with functional disorders of the gastrointestinal system but with normal IgG against H pylori. Endoscopic and histopathological evaluation of gastric mucosa was performed based on the Sydney System classification.The evaluation of sP-selectin, sIC AM-1, sVCAM-1 levels in the sera of children was carried out using ELISA test.RESULTS: The assessment of gastritis activity degrees indicated statistically significant values in the antrum and corpus (P<0.001) of children examined. Serum sVCAM-1 levels were higher in group with gastritis due to H pylori infection than in group without infection and differed statistically (P<0.05). Serum sVCAM-1 levels proved to be the highest among other adhesive molecules in infected children and decreased after eradication of H pylori. Serum sICAM-1 levels were similar in all examined groups. Serum sP-selectin levels were similar in children with and without H pylori infection.CONCLUSION: Assessment of adhesive molecules (sPselectin, sICAM-1, sVCAM-1) in the sera of children with active H pylori infection can show the participation of sVCAM-1 in the pathogenesis of gastric mucosal inflammation, sP-selectin and sICAM-1 concentrations in the sera of children with H pylori infection after eradication cannot reveal any significant differences as compared to healthy children. | Elzbieta Maciorkowska Maciej Kaczmarski Anatol Panasiuk Katarzyna Kondej-Muszynska Andrzej Kemonai | 2005 | World Journal of Gastroenterology2005，11，43： | 5 |
| 16 | Sodium alendronate loaded poly(L-lactideco-glycolide)microparticles immobilized on ceramic scaffolds for local treatment of bone defects显示文摘Bone tissue regeneration in critical-size defects is possible after implantation of a 3D scaffold and can be additionally enhanced once the scaffold is enriched with drugs or other factors supporting bone remodelling and healing.Sodium alendronate(Aln),a widely used anti-osteoporosis drug,exhibits strong inhibitory effect on bone resorption performed by osteoclasts.Thus,we propose a new approach for the treatment of bone defects in craniofacial region combining biocompatible titanium dioxide scaffolds and poly(L-lactide-co-glycolide)microparticles(MPs)loaded with Aln.The MPs were effectively attached to the surface of the scaffolds’pore walls by human recombinant collagen.Drug release from the scaffolds was characterized by initial burst(2466% of the drug released within first 24 h)followed by a sustained release phase(on average 5 mg of Aln released per day from Day 3 to Day 18).In vitro tests evidenced that Aln at concentrations of 5 and 2.5 mg/ml was not cytotoxic for MG-63 osteoblast-like cells(viability between 8166% and 9863% of control),but it prevented RANKL-induced formation of osteoclast-like cells from macrophages derived from peripheral blood mononuclear cells,as shown by reduced fusion capability and decreased tartrateresistant acid phosphatase 5b activity(5665% reduction in comparison to control after 8 days of culture).Results show that it is feasible to design the scaffolds providing required doses of Aln inhibiting osteoclastogenesis,reducing osteoclast activity,but not affecting osteoblast functions,which may be beneficial in the treatment of critical-size bone tissue defects. | Lucja Rumian Cornelia Wolf-Brandstetter Sina Roβler Katarzyna Reczynska Hanna Tiainen Havard J.Haugen Dieter Scharnweber Elzbieta Pamula | 2020 | Regenerative Biomaterials2020，7，3： | 5 |

| 19 | Phagocytic and oxidative burst activity of neutrophils in the end stage of liver cirrhosis显示文摘AIM: To evaluate the phagocytic activity and neutrophil oxidative burst in liver cirrhosis.METHODS: In 45 patients with advanced postalcoholic liver cirrhosis (aged 45±14 years) and in 25 healthy volunteers (aged 38±5 years), the percentage of phagocytizing cells after in vitro incubation with E. coli (Phagotest Kit), phagocytic activity (mean intensity of fluorescence, MIF) and the percentage of neutrophil oxidative burst (Bursttest Kit), and the level of free oxygen radical production (MIF of Rodamine 123)were analyzed by flow cytometry. The levels of soluble sICAM-1, sVCAM-1, sP-selectin, sE-selectin, sL-selectin,and TNF-α were determined in blood serum.RESULTS: The percentage of E. coli phagocytizing neutrophils in liver cirrhosis patients was comparable to that in healthy subjects. MIF of neutrophil - ingested E. coli was higher in patients with liver cirrhosis. The oxidative burst in E. coli phagocytizing neutrophils generated less amount of active oxygen compounds in liver cirrhosis patients (MIF of R123:24.7±7.1 and 29.7±6.6 in healthy,P<0.01). Phorbol myristate acetate (PMA) - stimulated neutrophilsproduced less reactive oxidants in liver cirrhosis patients than in healthy subjects (MIF of R123: 42.7±14.6 vs 50.2±13.3, P<0.01). A negative correlation was observed between oxidative burst MIF of PMA-stimulated neutrophils and ALT and AST levels (r -0.35, P<0.05;r-0.4, P<0.03). sVCAM-1, sICAM-1, sE-selectin concentrations correlated negatively with the oxygen free radical production (MIF of R123) in neutrophils after PMA stimulation in liver cirrhosis patients (r-0.45, P<0.05;r-0.41, P<0.05; r-0.39, P<0.05, respectively).CONCLUSION: Neutrophil metabolic activity diminishes together with the intensification of liver failure. The metabolic potential of phagocytizing neutrophils is significantly lower in liver cirrhosis patients, which can be one of the causes of immune mechanism damage. The evaluation of oxygen metabolism of E. coli-stimulated neutrophils reveals that the amount of released oxygen metabolites is smaller in liver cirrhosis patients than in healthy subjects. | Anatol Panasiuk Jolanta Wysocka Elzbieta Maciorkowska Bozena Panasiuk Danuta Prokopowicz Janusz Zak Karol Radomski | 2005 | World Journal of Gastroenterology2005，11，48： | 4 |
| 20 | 欧盟可再生能源市场和生物燃料的发展显示文摘文章旨在介绍可再生能源市场的发展,并特别关注欧盟的生物燃料。该分析包括可再生能源在岛屿总能源消费中所占份额,2004年~2016年可再生能源的变化和液体生物燃料数量的数据。笔者用描述性和统计方法来描述生物能源的变化欧洲联盟(EU)中生物能源发展的变化。生物燃料和可再生废物的最大份额出现在拉脱维亚(31.2%)、芬兰(26.7%)和瑞典(24.8%)。2015年风能比例最高的国家是丹麦(7.2%)、葡萄牙(4.3%)、爱尔兰(4.0%)和西班牙(3.5%)。2015年太阳能的最高份额出现在塞浦路斯(3.5%)、西班牙(2.6%)和希腊(2.2%)。2015年,地热能贡献最大的国家是意大利(3.5%)、葡萄牙(0.8%)和斯洛文尼亚(0.7%)。2015年,水力发电量最大的国家是瑞典(14.2%),奥地利(9.6%)和斯洛文尼亚(5.0%)。在2004年至2017年间,马耳他(140.3%)、塞浦路斯(101.1%)和英国(71.9%)的可再生能源电力份额变化系数最高。此外,2004-2017年间,可再生能源中供暖和制冷所占份额变动系数最高的是马耳他(72.4%)、英国(69.81%)和匈牙利(44.91%)。此外,2004~2017年在芬兰(113.78%),马耳他(115.52%)和比利时(96.53%)可再生能源中交通运输份额的变化系数最高。欧盟最大的乙醇和生物柴油生产商是德国、法国和波兰。聚类分析数据表明,德国和法国在生物柴油和乙醇生产中至关重要。在2003年至2017年间,生物柴油的产量从719.32亿升增加到133.23亿升(增长1852.2%)。然而,在2014年至2017年间,生物燃料生产停滞,从136.73亿升下降到133.23亿升(-2.56%)。到2030年,市场情况和对绿色能源需求的增加会引起乙醇和植物油酯的产量增加,这将为该部门的发展做出贡献。 | Piotr Borawski Aneta Beldycka-Borawska Elzbieta Jadwiga Szymanska Krzysztof Jozef Jankowski Bogdan Dubis James W Dunn 王健(译) | 2019 | 中国沼气2019，37，6： | 3 |
