3Remission induction and maintenance effect of probiotics on ulcerative colitis: A meta-analysis显示文摘AIM:To evaluate the induction of remission and main-tenance effects of probiotics for ulcerative colitis.METHODS: Information was retrieved from MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. The induction of remission and promotion of mainte-nance were compared between probiotics treatment and non-probiotics treatment in ulcerative colitis.RESULTS: Thirteen randomized controlled studies met the selection criteria. Seven studies evaluated the remission rate, and eight studies estimated the recur-rence rate; two studies evaluated both remission and recurrence rates. Compared with the non-probiotics group, the remission rate for ulcerative colitis patients who received probiotics was 1.35 (95% CI: 0.98-1.85). Compared with the placebo group, the remission rate of ulcerative colitis who received probiotics was 2.00 (95% CI: 1.35-2.96). During the course of treatment, in patients who received probiotics for less than 12 mo compared with the group treated by non-probiotics, the remission rate of ulcerative colitis was 1.36 (95% CI: 1.07-1.73). Compared with the non-probioticsgroup, the recurrence rate of ulcerative colitis patients who received probiotics was 0.69 (95% CI: 2.47-1.01). In the mild to moderate group who received probiotics, compared to the group who did not receive probiotics, the recurrence rate was 0.25 (95% CI: 0.12-0.51). The group who received Bifidobacterium bifidum treatment had a recurrence rate of 0.25 (95% CI: 0.12-0.50) compared with the non-probiotics group.CONCLUSION: Probiotic treatment was more effec-tive than placebo in maintaining remission in ulcerative colitis.Sang, Li-Xuan Chang, Bing Zhang, Wen-Liang Wu, Xiao-Mei Li, Xiao-Hang Jiang, Min 2010World Journal of Gastroenterology2010,16,15:44
4Long-term result of endoscopic Histoacryl (N-butyl-2-cyanoacrylate)injection for treatment of gastric varices显示文摘AIM:To evaluate the long-term efficacy and safety of endoscopic obliteration with Histoacryl  for treatment of gastric variceal bleeding and prophylaxis.METHODS:Between January 1994 and March 2010 at SoonChunHyang University Hospital,a total of 127 patients with gastric varices received Histoacryl  injections endoscopically.One hundred patients underwent endoscopic Histoacryl  injections because of variceal bleeding,the other 27 patients received such injections as a prophylactic procedure.RESULTS:According to Sarin classification,56 patients were GOV1,61 patients were GOV2 and 10 patients were IGV.Most of the varices were large(F2 or F3,111 patients).The average volume of Histoacryl  per each session was 1.7±1.3 cc and mean number of sessions was 1.3±0.6.(1 session-98 patients,2 sessions-25 patients,≥3 sessions-4 patients).Twenty-seven patients with high risk of bleeding(large or fundal or RCS+or Child C) received Histoacryl  injection as a primary prophylactic procedure.In these patients,hepatitis B virus was the major etiology of cirrhosis,25 patients showed GOV1 or 2(92.6%)and F2 or F3 accounted for 88.9%(n=24).The rate of initial hemostasis was 98.4%and recurrent bleeding within one year occurred in 18.1%of patients.Successful hemostasis during episodes of rebleeding was achieved in 73.9%of cases.Median survival was 50 mo (95%CI 30.5-69.5).Major complications occurred in 4 patients(3.1%).The rebleeding rate in patients with hepatocellular carcinoma or GOV2 was higher than in those with other conditions.None of the 27 subjects who were treated prophylactically experienced treatment-related complications.Cumulative survival rates of the 127 patients at 6 mo,1,3,and 5 years were 92.1%,84.2%,64.2%,and 45.3%,respectively.The 6 mo cumulative survival rate of the 27 patients treated prophylactically was 75%.CONCLUSION:Histoacryl  injection therapy is an effective treatment for gastric varices and also an effective prophylactic treatment of gastric varices which carry high risk of bleeding.Eun Jung Kang Soung Won Jeong Jae Young Jang Joo Young Cho Sae Hwan Lee Hyun Gun Kim Sang Gyune Kim Young Seok Kim Young Koog Cheon Young Deok Cho Hong Soo Kim Boo Sung Kim 2011World Journal of Gastroenterology2011,17,11:41
5Clinical implications of fatty pancreas:Correlations between fatty pancreas and metabolic syndrome显示文摘AIM:To investigate the clinical implications of lipid deposition in the pancreas(fatty pancreas). METHODS:The subjects of this study were 293 patients who had undergone abdominal computed tomography(CT)and sonography.Fatty pancreas was diagnosed by sonographic findings and subdivided into mild,moderate,and severe fatty pancreas groups comparing to the retroperitoneal fat echogenicity. RESULTS:Fatty pancreas was associated with higher levels for visceral fat,waist circumference,aspartate aminotransferase(AST),alanine aminotransferase (ALT),total cholesterol,triglyceride,high density lipoprotein,free fatty acid,γ-GTP,insulin,and the homeostasis model assessment of insulin resistance (HOMA-IR)than the control group(P<0.05).HOMAIR,visceral fat,triglyceride,and ALT also tended to increase with the degree of fat deposition in the pancreas on sonography.In a multivariate logistic regression analysis,HOMA-IR,visceral fat,and ALT level were independently related to fatty pancreas after adjustment for age,body mass index,and lipid profile.The incidence of metabolic syndrome in the fatty pancreas group was significantly higher than in the control group,and the numbers of metabolic syndrome parameters were significantly higher in the fatty pancreas group(P<0.05).CONCLUSION:Sonographic fatty pancrease showed higher insulin resistance,visceral fat area,triglyceride, and ALT levels than normal pancreases.Fatty pancreas also showed a strong correlation with metabolic syndrome.Jun Seok Lee Sang Heum Kim Dae Won Jun Jee Hye Han Eun Chul Jang Ji Young Park Byung Kwan Son Seong Hwan Kim Yoon Ju Jo Young Sook Park Yong Soo Kim 2009World Journal of Gastroenterology2009,15,15:40
6Complex role of matrix metalloproteinases in angiogenesis显示文摘Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMP) play a significant role in regulating angiogenesis, the process of new blood vessel formation. Interstitial collagenase (MMP-1), 72 kDa gelatinase A/type IV collagenase (MMP-2), and 92 kDa gelatinase B/type IV collagenase (MMP-9) dissolve extracellular matrix (ECM) and may initiate and Promote angiogenesis. TIMP-1, TIMP-2, TIMP-3, and possibly,TIMP-4 inhibit neovascularisation. A new paradigm is emerging that matrilysin (MMP-7), MMP-9, and metalloelastase (MMP-12) may block angiogehesis by converting plasndnogen to angiostatin, which is one of the most potent angiogenesis antagonists. MMPs and TIMPs play a complex role in regulating angiogenesis. An understanding of the biochemical and cellular pathways and mechanisms of angiogenesis will provide importal information to allow the control of angiogenesis, e.g. the stimulation of angiogenesis for coronary collateral circulation formation; while the inhibition for treating arthritis and cancer.SANG QING XIANG AMY(Biochemistry Division, Department of Chemistry, Florida State University, Tallahassee, Florida 32306-4390, USA) 1998Cell Research1998,8,3:40
7Bacterial infection after liver transplantation显示文摘Infectious complications are major causes of morbidity and mortality after liver transplantation,despite recent advances in the transplant field.Bacteria,fungi,viruses and parasites can cause infection before and after transplantation.Among them,bacterial infections are predominant during the first two months posttransplantation and affect patient and graft survival.They might cause surgical site infections,including deep intra-abdominal infections,bacteremia,pneumonia,catheter-related infections and urinary tract infections.The risk factors for bacterial infections differ between the periods after transplant,and between centers.Recently,the emergence of multi-drug resistant bacteria is great concern in liver transplant(LT)patients.The instructive data about effects of infections with extended-spectrum beta lactamase producing bacteria,carbapenem-resistant gram-negative bacteria,and glycopeptide-resistant gram-positive bacteria were reported on a center-by-center basis.To prevent posttransplant bacterial infections,proper strategies need to be established based upon center-specific data and evidence from well-controlled studies.This article reviewed the recent epidemiological data,risk factors for each type of infections and important clinical issues in bacterial infection after LT.Sang Il Kim 2014World Journal of Gastroenterology2014,20,20:38

12Selective COX-2 inhibitor,NS-398,suppresses cellular proliferation in human hepatocellular carcinoma cell lines via cell cycle arrest显示文摘AIM: To investigate the growth inhibitory mechanism of NS-398, a selective cyclooxygenase-2 (COX-2) inhibitor, in two hepatocellular carcinoma (HCC) cell lines (HepG2 and Huh7). METHODS: HepG2 and Huh7 cells were treated with NS-398. Its effects on cell viability, cell proliferation, cell cycles, and gene expression were respectively evaluated by water-soluble tetrazolium salt (WST-1) assay, 4’-6-diamidino-2-phenylindole (DAPI) staining, flow cytometer analysis, and Western blotting, with dimethyl sulfoxide (DMSO) as positive control. RESULTS: NS-398 showed dose- and time-dependent growth-inhibitory effects on the two cell lines. Proliferating cell nuclear antigen (PCNA) expressions in HepG2 and Huh7 cells, particularly in Huh7 cells were inhibited in a time- and dose-independent manner. NS-398 caused cell cycle arrest in the G1 phase with cell accumulation in the sub-G1 phase in HepG2 and Huh7 cell lines. No evidence of apoptosis was observed in two cell lines. CONCLUSION: NS-398 reduces cell proliferation by inducing cell cycle arrest in HepG2 and Huh7 cell lines, and COX-2 inhibitors may have potent chemoprevention effects on human hepatocellular carcinoma.Ji Yeon Baek Wonhee Hur Jin Sang Wang Si Hyun Bae Seung Kew Yoon 2007World Journal of Gastroenterology2007,13,8:27
13Pre-operative factors that can predict neoplastic polypoid lesions of the gallbladder显示文摘AIM:To investigate the preoperative factors that can predict neoplastic polypoid lesions of the gallbladder(PLGs) as well as malignant PLGs.METHODS:A retrospective analysis was conducted on the 210 consecutively enrolled patients who underwent cholecystectomy due to a PLG larger than 10 mm,as was determined by preoperative trans-abdominal ultrasonography or endoscopic ultrasonography.We ana-lyzed the medical,laboratory,radiologic data and the pathologic results.RESULTS:In 210 cases,146 had non-neoplastic polyps(69.5%) and 64 cases were neoplastic polyps(30.5%).An older age(≥ 65 years),the presence of diabetes mellitus(DM) and the size of polyp(≥ 15 mm) were revealed to be independent predictive variables for neoplastic polyps with odd ratios(OR) of 2.27(P = 0.044),2.64(P = 0.021) and 4.94(P < 0.01),respectively.Among the neoplastic PLGs,an older age(≥ 65 years),the presence of DM and polyp size(≥ 15 mm) were associated with malignancy with ORs of 4.97(P = 0.005),6.13(P = 0.001) and 20.55(P < 0.001),respectively.CONCLUSION:Among patients with PLGs larger than 10 mm in size,higher risk groups such as elderly patients more than 65 years old,those with DM or a large polyp size(≥ 15 mm) should be managed by cholecystectomy.Byung Hyo Cha Jin-Hyeok Hwang Sang Hyub Lee Jang Eon Kim Jai Young Cho Haeryoung Kim So Yeon Kim 2011World Journal of Gastroenterology2011,17,17:27
14Postoperative adjuvant antiviral therapy for hepatitis B/C virus-related hepatocellular carcinoma:A meta-analysis显示文摘AIM:To investigate the impact of postoperative antiviral treatment on tumor recurrence and survival of patients with chronic hepatitis B virus(HBV) or hepatitis C virus(HCV) infection-related primary hepatocellular carcinoma(HCC) after curative therapy.METHODS:We performed a meta-analysis of randomized and non-randomized control trials from electronic search and manual search.The fixed effect model of Mantel-Haenszel method and the random effect model of Der Simonian and Laird method were used for homogeneous and heterogeneous studies,respectively.Seven HCV-related studies,three HBV-related studies and three studies on HBV or HCV-related HCC were identified.RESULTS:A total of 1224 patients were included in this analysis.The estimated odds ratios(OR) for the 1-,2-,3-and 5-year recurrence were 0.54 [15.4% vs 24.1%,95% confidence interval(CI):0.32-0.89,P=0.02],0.42(36.9% vs 58.0%,95% CI:0.19-0.90,P=0.03),0.37(47.9% vs 63.8%,95% CI:0.19-0.71,P=0.003),and 0.32(66.7% vs 74.3%,95% CI:0.15-0.66,P=0.002),respectively;and the OR for the 1-,2-,3-,5-and 7-year mortality were 0.23(1.2% vs 9.1%,95% CI:0.07-0.71,P=0.01),0.31(6.4% vs 22.1%,95% CI:0.12-0.79,P=0.01),0.43(12.7% vs 20.8%,95% CI:0.21-0.89,P=0.02),0.42(25.1% vs 42.0%,95% CI:0.27-0.66,P=0.0002) and 0.28(31.9% vs 52.2%,95% CI:0.13-0.59,P=0.0008).CONCLUSION:This meta-analysis indicates the postoperative antiviral therapy,interferon in particular,may serve as a favorable alternative to reduce recurrence and mortality in patients with HBV/HCV related HCCs.Miao, Ruo-Yu Zhao, Hai-Tao Yang, Hua-Yu Mao, Yi-Lei Lu, Xin Zhao, Yi Liu, Chang-Ning Zhong, Shou-Xian Sang, Xin-Ting Huang, Jie-Fu 2010World Journal of Gastroenterology2010,16,23:26

16Chinese Trauma Surgeon Association for management guidelines of vacuum sealing drainage application in abdominal surgeries-Update and systematic review显示文摘Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chin ese Trauma Surge on Associati on orga nized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries.Eleven questions regarding the use of VSD in abdominal surgeries were addressed:(1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions?(2) Can VSD be preventively used for a high-risk abdominal incision w让h primary suture?(3) Can VSD be used in severely contaminated/infected abdominal surgical sites?(4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome?(5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage?(6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula?(7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess?(8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects?(9) Does VSD in crease the risk of bleeding?(10) Does VSD increase the risk of intestinal wail injury?(11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.Yang Li Pei-Yuan Li Shi-Jing Sun Yuan-Zhang Yao Zhan-Fei Li Tao Liu Fan Yang Lian-Yang Zhang Xiang-Jun Bai Jing-Shan Huo Wu-Bing He Jun Ouyang Lei Peng Ping Hu Yan-An Zhu Ping Jin Qi-Feng Shao Yan-Feng Wang Rui-Wu Dai Pei-Yang Hu Hai-Ming Chen Ge-Fei Wang Yong-Gao Wang Hong-Xu Jin Chang-Ju Zhu Qi-Yong Zhang Biao Shao Xi-Guang Sang Chang-Lin Yin 2019Chinese Journal of Traumatology2019,22,1:26
17Temozolomide resistance in glioblastoma multiforme显示文摘Temozolomide(TMZ)is an oral alkylating agent used to treat glioblastoma multiforme(GBM)and astrocytomas.However,at least 50%of TMZ treated patients do not respond to TMZ.This is due primarily to the over-expression of O6-methylguanine methyltransferase(MGMT)and/or lack of a DNA repair pathway in GBM cells.Multiple GBM cell lines are known to contain TMZ resistant cells and several acquired TMZ resistant GBM cell lines have been developed for use in experiments designed to define the mechanism of TMZ resistance and the testing of potential therapeutics.However,the characteristics of intrinsic and adaptive TMZ resistant GBM cells have not been systemically compared.This article reviews the characteristics and mechanisms of TMZ resistance in natural and adapted TMZ resistant GBM cell lines.It also summarizes potential treatment options for TMZ resistant GBMs.Sang Y.Lee 2016Genes & Diseases2016,3,3:26
18Comparison of the efficacy and safety of sedation between dexmedetomidine-remifentanil and propofol-remifentanil during endoscopic submucosal dissection显示文摘AIM: To compare the efficacy and safety of sedation protocols for endoscopic submucosal dissection(ESD) between dexmedetomidine-remifentanil and propofolremifentanil.METHODS: Fifty-nine patients scheduled for ESD were randomly allocated into a dexmedetomidineremifentanil(DR) group or a propofol-remifentanil(PR) group. To control patient anxiety, dexmedetomidine or propofol was infused to maintain a score of 4-5 on the Modified Observer's Assessment of Alertness/Sedation scale. Remifentanil was infused continuously at a rate of 6 μg/kg per hour in both groups. The ease of advancing the scope into the throat, gastric motility grading, and satisfaction of the endoscopist and patient were assessed. Hemodynamic variables and hypoxemic events were compared to evaluate patient safety.RESULTS: Demographic data were comparable between the groups. The hemodynamic variables and pulse oximetry values were stable during the procedure in both groups despite a lower heart rate in the DR group. No oxygen desaturation events occurred in either group. Although advancing the scope into the throat was easier in the PR group('very easy' 24.1% vs 56.7%, P = 0.010), gastric motility was moresuppressed in the DR group('no + mild' 96.6% vs 73.3%, P = 0.013). The endoscopists felt that the procedure was more favorable in the DR group('very good + good' 100% vs 86.7%, P = 0.042), whereas patient satisfaction scores were comparable between the groups. En bloc resection was performed 100% of the time in both groups, and the complete resection rate was 94.4% in the DR group and 100% in the PR group(P = 0.477). CONCLUSION: The efficacy and safety of dexmedetomidine and remifentanil were comparable to propofol and remifentanil during ESD. However, the endoscopists favored dexmedetomidine perhaps due to lower gastric motility.Namo Kim Young-Chul Yoo Sang Kil Lee Hyunzu Kim Hyang Mi Ju Kyeong Tae Min 2015World Journal of Gastroenterology2015,21,12:25
19Current management of hepatocellular carcinoma:An Eastern perspective显示文摘Hepatocellular carcinoma(HCC) is one of the leading causes of cancer death, especially in Eastern areas. With advancements in diagnosis and treatment modalities for HCC, the survival and prognosis of HCC patients are improving. However, treatment patterns are not uniform between areas despite efforts to promote a common protocol. Although many hepatologists in Asian countries may adopt the principles of the Barcelona Clinic Liver Cancer staging system, they are also independently making an effort to expand the indications of each treatment and to combine therapies for better outcomes. Several expanded criteria for liver transplantation in HCC have been developed in Asian countries. Living donor liver transplantation is much more commonly performed in these countries than deceased donor liver transplantation, and it may be preceded by other treatments such as the down-staging of tumors. Local ablation therapies are often combined with transarterial chemoembolization( TACE) and the outcome is comparable to that of surgical resection. The indications of TACE are expanding, and there are new types of transarterial therapies. Although data on drug-eluting beads, TACE, and radioembolization in Asian countries are still relatively sparse compared with Western countries, these methods are gradually gaining popularity because of better tolerability and the possibility of improved response rates. Hepatic arterial infusion chemotherapy and radiotherapy are not included in Western guidelines, but are currently being used actively in several Asian countries. For more advanced HCCs, appropriate combinations of TACE, radiotherapy, and sorafenib can be considered, and emerging data indicate improved outcomes of combination therapies compared with single therapies. To include these paradigm shifts into newer treatment guidelines, more studies may be needed, but they are certainly in progress.Hyung Joon Yim Sang Jun Suh Soon Ho Um 2015World Journal of Gastroenterology2015,21,13:26
20Laser cleaning of steel structure surface for paint removal and repaint adhesion显示文摘Paint removal from steel structure is executed for shipyards of marine and offshore engineering.Due to environmental unfriendliness and unhealthy drawbacks of sand blasting technique, laser ablation technique is proposed as a substituting method.By absorbing high energy of the 1064 nm pulsed laser, the paint is vaporized quickly.The ablated debris is then collected by using a suction pump.Initial metal surface of the steel is exposed when laser beam irradiates perpendicularly and scans over it.The cleaned surface fulfills the requirements of surface preparation standards ISO 8501 of SA2.The adhesion is further characterized with pull-off test after carrying out painting with Jotamastic 87 aluminum paint.The repainting can be embedded onto the laser cleaned surface to bond much more tightly.The excellent adhesion strength of 20 MPa between repainted coating and the substrate is achieved, which is higher than what is required by shipyards applications.Xiaoguang Li Tingting Huang Ang Wei Chong Rui Zhou Yoo Sang Choo Minghui Hong 2017光电工程2017,44,3:24
