| 1 | Serum IL-6, TNFα and CRP levels in Greek colorectal cancer patients: Prognostic implications显示文摘AIM: The significance of preoperative serum IL-6, TNFαand CRP levels in the progression of colorectal cancer (CRC) has not been fully elucidated. Our intention was to investigate their role and identify their prognostic significance.METHODS: The IL-6, TNFα and CRP levels were measured in 74 CRC patients and the relationships between their elevation s and both the clinicopathological factors and prognosis of patients were investigated. Serum concentrations of human IL-6 and TNFα were determined by enzyme-linked immunosorbent assay (ELISA). CRP was measured by an immunoturbinometric method.RESULTS: Median IL-6, TNFα and CRP levels weresignificantly higher in CRC patients than in normal controls.High levels of serum IL-6, TNFα and CRP were correlated with larger tumor size. Furthermore, high IL-6 and high CRP levels were associated with reduced overall survival.CONCLUSION: Serum IL-6, TNFα and CRP levels definitely increase in CRC patients. Pre-operative serum elevation of IL-6 and CRP was thus found to be predictor of the prognosis of CRC patients. The clinical value of TNFα in CRC needs to be further investigated. | Nikolaos I.

| 2 | Type 2 diabetes is associated with a worse functional outcome of ischemic stroke显示文摘AIM: To assess whether ischemic stroke severity and outcome is more adverse in patients with type 2 diabetes mellitus(T2DM). METHODS: Consecutive patients hospitalized for acute ischemic stroke between September 2010 and June 2013 were studied prospectively(n = 482; 40.2% males, age 78.8 ± 6.7 years). T2 DM was defined as self-reported T2 DM or antidiabetic treatment. Stroke severity was evaluated with the National Institutes of Health Stroke Scale(NIHSS) score at admission. The outcome was assessed with the modified Rankin scale(m RS) score at discharge and with in-hospital mortality. Adverse outcome was defined as m RS score at discharge ≥ 2 or in-hospital death. The length of hospitalization was also recorded.RESULTS: T2 DM was present in 32.2% of the study population. Patients with T2 DM had a larger waist circumference, higher serum triglyceride and glucose levels and lower serum high-density lipoprotein cholesterol levels as well as higher prevalence of hypertension, coronary heart disease and congestive heart failure than patients without T2 DM. On the other hand, diabetic patients had lower low-density lipoprotein cholesterol levels and reported smaller consumption of alcohol than non-diabetic patients. At admission, the NIHSS score did not differ between patients with and without T2DM(8.7 ± 8.8 and 8.6 ± 9.2, respectively; P = NS). At discharge, the m RS score also did not differ between the two groups(2.7 ± 2.1 and 2.7 ± 2.2 in patients with and without T2 DM, respectively; P = NS). Rates of adverse outcome were also similar in patients with and without T2DM(62.3% and 58.5%, respectively; P = NS). However, when we adjusted for the differences between patients with T2 DM and those without T2 DM in cardiovascular risk factors, T2 DM was independently associated with adverse outcome [relative risk(RR) = 2.39; 95%CI: 1.21-4.72, P = 0.012]. Inhospital mortality rates did not differ between patients with T2 DM and those without T2DM(9.0% and 9.8%, respectively; P = NS). In multivariate analysis adjusting for the difference in cardiovascular risk factors between the two groups, T2 DM was again not associated with in-hospital death. CONCLUSION: T2 DM does not appear to affect ischemic stroke severity but is independently associated with a worse functional outcome at discharge. | Konstantinos Tziomalos Marianna Spanou Stella D Bouziana Maria Papadopoulou Vasilios Giampatzis Stavroula Kostaki Vasiliki Dourliou Maria Tsopozidi Christos Savopoulos Apostolos I Hatzitolios | 2014 | World Journal of Diabetes2014，5，6： | 15 |
| 3 | An alternative surgical approach to a difficult case of Mirizzi syndrome: A case report and review of the literature显示文摘Mirizzi syndrome (MS) is an uncommon complication of gallstone disease and occurs in approximately 1% of all patients suffering from cholelithiasis. The syndrome is characterized by extrinsic compression of the common hepatic duct frequently resulting in clinical presentation of intermittent or constant jaundice. Most cases are not identifi ed preoperatively. Surgery is the indicated treat- ment for patients with MS. We report here a 71-year- old male patient referred to the surgical outpatient department for diffuse upper abdominal pain and mild jaundice (bilirubin rate: 4.2 mg/dL). Ultrasound examina- tion revealed a stone in the cystic duct compressing the common hepatic duct. The patient had a history of gas- trectomy for gastric ulcer 30 years ago. MRCP revealed a stone impacted in the cystic duct causing obstruction of the common hepatic duct by extrinsic compression. With these fi ndings the preoperative diagnosis was indicative of MS. At laparotomy a moderately shrunken gallbladder was found embedded in adhesions containing a large stone which was palpable in the common bile duct. The anterior wall of the body of the gallbladder was opened by an incision which extended longitudinally along the gallbladder towards the common bile duct. The stone measuring 3.0 cm in diameter, was then removed set- ting astride a large communication with the common bile duct. A Roux-en-Y cholecysto-choledocho-jejunostomy was performed. The subhepatic region was drained. The patient had an uneventful recovery. He was discharged eleven days after operation and remained well after a 30-mo follow-up. | Michael Safioleas Michael Stamatakos Constantinos Revenas Constantinos Chatziconstantinou Constantinos Safioleas Alkiviades Kostakis | 2006 | World Journal of Gastroenterology2006，12，34： | 13 |
| 4 | Circulating lymphangiogenic growth factors in gastrointestinal solid tumors, could they be of any clinical significance?显示文摘Metastasis is the principal cause of cancer mortality, with the lymphatic system being the first route of tumor dissemination. The glycoproteins VEGF-C and VEGF-D are members of the vascular endothelial growth factor (VEGF) family, whose role has been recently recognized as lymphatic system regulators during embryogenesis and in pathological processes such as inflammation, lymphatic system disorders and malignant tumor metastasis. They are ligands for the VEGFR-3 receptor on the membrane of the lymphatic endothelial cell, resulting in dilatation of existing lymphatic vessels as well as in vegetation of new ones (lymphangiogenesis). Their determination is feasible in the circulating blood by immunoabsorption and in the tissue specimen by immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR). Experimental and clinicopathological studies have linked the VEGF-C, VEGF-D/VEGFR3 axis to lymphatic spread as well as to the clinical outcome in several human solid tumors. The majority of these data are derived from surgical specimens and malignant cell series, rendering their clinical application questionable, due to subjectivity factors and post-treatment quantification. In an effort to overcome these drawbacks, an alternative method of immunodetection of the circulating levels of these molecules has been used in studies on gastric, esophageal and colorectal cancer. Their results denotethat quantification of VEGF-C and VEGF-D in blood samples could serve as lymph node metastasis predictive biomarkers and contribute to preoperative staging of gastrointestinal malignancies. | Theodore D Tsirlis George Papastratis Kyriaki Masselou Christos Tsigris Antonis Papachristodoulou Alkiviadis Kostakis Nikolaos I Nikiteas | 2008 | World Journal of Gastroenterology2008，14，17： | 12 |
| 5 | Clinical considerations and therapeutic strategy for sigmoid volvulus in the elderly:A study of 33 cases显示文摘AIM: To evaluate different types of treatment for sigmoid volvulus and clarify the role of endoscopic intervention versus surgery. METHODS: A retrospective review of the clinical presentation and imaging characteristics of 33 sigmoid volvulus patients was presented, as well as their diagnosis and treatment, in combination with a literature review. RESULTS: In 26 patients endoscopic detorsion was achieved after the first attempt and one patient died because of uncontrollable sepsis despite prompt operative treatment. Seven patients had unsuccessful endoscopic derotation and were operated on. On two patients with gangrenous sigmoid, Hartmann's procedure was performed. In five patients with viable colon, a sigmoid resection and primary anastomosis was carried out. Three patients had a lavage 'on table' prior to anastomosis, while in the remaining 2 patients a diverting stoma was performed according to the procedure of the first author. Ten patients were operated on during their first hospital stay (3 to 8 d after the deflation). All patients had viable colon; 7 patients had a sigmoid resection and primary anastomosis, 2 patients had sigmoidopexy and one patient underwent a near-total colectomy. Two patients (sigmoidectomy-sigmoidopexy) had recurrences of volvulus 43 and 28 mo after the initial surgery. Among 15 patients who were discharged from the hospital after non-operative deflation, 3 patients were lost to follow-up. Of theremaining 12 patients, 5 had a recurrence of volvulus at a time in between 23 d and 14 mo. All the five patients had been operated on and in four a gangrenous sigmoid was found. Three patients died during the 30 d postoperative course. The remaining seven patients were admitted to our department for elective surgery. In these patients, 2 subtotal colectomies, 3 sigmoid resections and 2 sigmoidopexies were carried out. One patient with subtotal colectomy died. Taken together of the results, it is evident that after 17 elective operations we had only one death (5.9%), whereas after 15 emergency operations 6 patients died, which means a mortality rate of 40%. CONCLUSION: Although sigmoid volvulus causing intestinal obstruction is frequently successfully encountered by endoscopic decompression, however, the principal therapy of this condition is surgery. Only occasionally in patients with advanced age, lack of bowel symptoms and multiple co-morbidities might surgical repair not be considered. | Michael Safioleas Constantinos Chatziconstantinou Evangelos Felekouras Michael Stamatakos Ioannis Papaconstantinou Anastasios Smirnis Panagiotis Safioleas Alkiviades Kostakis | 2007 | World Journal of Gastroenterology2007，13，6： | 10 |

| 7 | 在不含酒精的脂肪肝疾病和尖锐 ischemic 击严厉和结果之间的协会显示文摘 AIM:To evaluate the association of nonalcoholic fatty liver disease(NAFLD)with acute ischemic stroke severity and in-hospital outcome.METHODS:We prospectively studied all patients who were admitted in our Department with acute ischemic stroke between September 2010 and August 2012(n=415;39.5%males,mean age 78.8±6.6 years).The severity of stroke was assessed with the National Institutes of Health Stroke Scale(NIHSS)score at admission.NALFD was defined as serum alanine aminotransferase and/or aspartate aminotransferase levels above the upper limit of normal in the absence of other causes of elevated aminotransferases levels[chronic hepatitis B or C,drug toxicity,increased alcohol consumption(>21 and>14 drinks per week in men and women,respectively),cholestatic diseases or rhabdomyolysis].The outcome was assessed with the modified Rankin scale(mRS)score at discharge and in-hospital mortality.Adverse outcome was defined as mRS score at discharge≥2.Dependency at discharge was defined as mRS score between 2 to 5.RESULTS:NAFLD was present in 7.7%of the study population.Patients with NAFLD had lower serum high-density lipoprotein cholesterol and higher triglyceride levels than patients without NAFLD(P<0.05 for both comparisons).Demographic data,the prevalence of other cardiovascular risk factors and the prevalence of established CVD did not differ between the two groups.At admission,the NIHSS score did not differ between patients with and without NAFLD(6.3±6.4and 8.8±9.6,respectively;P=NS).At discharge,the mRS score did not differ between the two groups(1.9±2.2 and 2.6±2.2 in patients with and without NAFLD,respectively;P=NS).Rates of dependency at discharge were also similar in patients with and without NAFLD(36.8%and 55.0%,respectively;P=NS)as were the rates of adverse outcome(42.9%and58.6%,respectively;P=NS).In-hospital mortality rates also did not differ between the 2 groups(8.0%and 7.0%in patients with and without NAFLD,respectively;P=NS).CONCLUSION:The presence of NAFLD in patients admitted for acute ischemic stroke does not appear to be associated with more severe stroke or with worse in-hospital outcome. | Konstantinos Tziomalos Vasilios Giampatzis Stella D Bouziana Marianna Spanou Maria Papadopoulou Athinodoros Pavlidis Stavroula Kostaki Andreas Bozikas Christos Savopoulos Apostolos I Hatzitolios | 2013 | World Journal of Hepatology2013，5，11： | 2 |
| 8 | Efficient differentiation of vascular smooth muscle cells from Wharton's Jelly mesenchymal stromal cells using human platelet lysate: A potential cell source for small blood vessel engineering显示文摘BACKGROUND The development of fully functional small diameter vascular grafts requires both a properly defined vessel conduit and tissue-specific cellular populations.Mesenchymal stromal cells(MSCs) derived from the Wharton's Jelly(WJ) tissue can be used as a source for obtaining vascular smooth muscle cells(VSMCs),while the human umbilical arteries(h UAs) can serve as a scaffold for blood vessel engineering.AIM To develop VSMCs from WJ-MSCs utilizing umbilical cord blood platelet lysate.METHODS WJ-MSCs were isolated and expanded until passage(P) 4. WJ-MSCs were properly defined according to the criteria of the International Society for Cell and Gene Therapy. Then, these cells were differentiated into VSMCs with the use of platelet lysate from umbilical cord blood in combination with ascorbic acid,followed by evaluation at the gene and protein levels. Specifically, gene expression profile analysis of VSMCs for ACTA2, MYH11, TGLN, MYOCD, SOX9,NANOG homeobox, OCT4 and GAPDH, was performed. In addition,immunofluorescence against ACTA2 and MYH11 in combination with DAPI staining was also performed in VSMCs. HUAs were decellularized and served as scaffolds for possible repopulation by VSMCs. Histological and biochemical analyses were performed in repopulated h UAs.RESULTS WJ-MSCs exhibited fibroblastic morphology, successfully differentiating into'osteocytes', 'adipocytes' and 'chondrocytes', and were characterized by positive expression(> 90%) of CD90, CD73 and CD105. In addition, WJ-MSCs were successfully differentiated into VSMCs with the proposed differentiation protocol. VSMCs successfully expressed ACTA2, MYH11, MYOCD, TGLN and SOX9. Immunofluorescence results indicated the expression of ACTA2 and MYH11 in VSMCs. In order to determine the functionality of VSMCs, h UAs were isolated and decellularized. Based on histological analysis, decellularized h UAs were free of any cellular or nuclear materials, while their extracellular matrix retained intact. Then, repopulation of decellularized h UAs with VSMCs was performed for 3 wk. Decellularized h UAs were repopulated efficiently by the VSMCs. Biochemical analysis revealed the increase of total hydroyproline and s GAG contents in repopulated h UAs with VSMCs. Specifically, total hydroxyproline and s GAG content after the 1 st, 2 nd and 3 rd wk was 71 ± 10, 74 ± 9 and 86 ± 8 μg hydroxyproline/mg of dry tissue weight and 2 ± 1, 3 ± 1 and 3 ± 1μg s GAG/mg of dry tissue weight, respectively. Statistically significant differences were observed between all study groups(P<0.05).CONCLUSION VSMCs were successfully obtained from WJ-MSCs with the proposed differentiation protocol. Furthermore, h UAs were efficiently repopulated by VSMCs. Differentiated VSMCs from WJ-MSCs could provide an alternative source of cells for vascular tissue engineering. | Panagiotis Mallis Aggeliki Papapanagiotou Michalis Katsimpoulas Alkiviadis Kostakis Gerasimos Siasos Eva Kassi Catherine Stavropoulos-Giokas Efstathios Michalopoulos | 2020 | World Journal of Stem Cells2020，12，3： | 2 |
| 9 | Benign multicystic peritoneal mesothelioma: A case report and review of the literature显示文摘Benign multicystic peritoneal mesothelioma (BMPM) is a rare tumor that occurs mainly in women in their reproductive age. The pathogenesis of BMPM is unclear and a controversy regarding its neoplastic and reactive nature exists. The biological behavior of BMPM is characterized by its slowly progressive process and high rate of recurrence after surgical resection. In addition this lesion does not present a strong tendency to transform into malignancy. Today approximately 130 cases have been reported. We here report a 62-year-old woman who had diffuse abdominal pain, nausea and vomiting. Physical examination revealed a painful mass in her upper abdomen. She reported a mild dehydration, but the vital signs were normal. Peristaltic rushes, gurgles and high- pitched tinkles were audible. Upright plain abdominal film revealed small bowel loops with air-fluid levels. She was diagnosed having an incarcerated incisional hernia that resulted in intestinal obstruction. The patient underwent surgery during which a cystic mass of the right ovary measuring 6 cm x 5 cm x 4 cm, four small cysts of the small bowel (1 cm in diameter) and a cyst at the retroperitoneum measuring 11 cm x 10 cm x 3 cm were found. Complete resection of the lesion was performed. The patient had an uneventful recovery and had no recurrence two years after surgery. | Michael C Safioleas Kontzoglou Constantinos Stamatakos Michael Giaslakiotis Konstantinos Safioleas Constantinos Kostakis Alkiviadis | 2006 | World Journal of Gastroenterology2006，12，35： | 2 |
