| 1 | siRNA targeting Livin decreases tumor in a xenograft model for colon cancer显示文摘AIM: To evaluate the effect of silencing Livin gene expression with siRNA to apoptosis and proliferation in a colon cancer cell line.METHODS: To investigate the anticancer effect of silencing Livin gene expression, we established an siRNA transfected cell line using the HCT116 colon cancer cell line. After confirming the successful transfection, MTT assay, flow cytometry and annexin V staining were employed to evaluate the antiapoptotic effect. To confirm the in vivo effect of Livin-siRNA, different doses of LivinsiRNA were injected into xenografted tumors in BALB/c nude mice model.RESULTS: Livin expression was dramatically decreased after siRNA transfection, especially at 25 μmol/L of siRNA, but this suppression was not dose-dependent. The cell count at 18 h after transfection was significantly reduced as compared with controls (P < 0.01), but tended not to decrease proportionally depending on transfected doseor time. MTT assay revealed that silencing the Livin gene suppressed cellular proliferation at 18 h after transfection (P = 0.04); however, the inhibitory effect disappeared thereafter. Also, there was no significant difference in cel- lular proliferation depending on siRNA dose. The rate of apoptosis also increased with silencing of the Livin gene. In vivo , the tumor size significantly decreased after Livin- siRNA injection at 20 μmol/L concentration (P = 0.03). There were no significant body weight changes of mice after siRNA injection. Histologic examination revealed no significant toxic reaction in kidney, liver and brain of mice. CONCLUSION: siRNA-mediated downregulation of Livin expression can induce apoptosis in colon cancer in vitro and in vivo , which suggests the possibility of new cancer therapeutics using siRNA. | Bo-Young Oh Ryung-Ah Lee Kwang Ho Kim | 2011 | World Journal of Gastroenterology2011，17，20： | 15 |
| 2 | Endoscopic features suggesting gastric cancer in biopsy-proven gastric adenoma with high-grade neoplasia显示文摘AIM:To elucidate the endoscopic features that predict the cancer following endoscopic submucosal dissection(ESD)in patients with high-grade neoplasia(HGN).METHODS:We retrospectively analyzed the medical records of patients who underwent ESD of gastric neoplasms from January 2007 to September 2010.ESD was performed in 555 cases involving 550 patients.A total of 112 lesions from 110 consecutive patients were initially diagnosed as HGN without cancer by forceps biopsy,and later underwent ESD.We classified lesions into two groups according to histologic discrepancies between the biopsy and ESD diagnosis.Gastric adenoma in the final diagnosis by ESD specimens were defined as adenoma group.Lesions with coexisting cancer after ESD were defined as cancer group.RESULTS:The mean age was 65.3 years,and 81 patients were male.There was no significant difference in the age or gender distribution between the adenoma(n=52)and cancer(n=60)groups.Thirty-six of these lesions(32.1%)showed histologic concordance between the forceps biopsy and ESD specimens,16(14.3%)showed a downgraded histology(low-grade neoplasia),and 60(53.6%)showed an upgraded histology(cancer).A red color change of the mucosal surface on endoscopy was found in 27/52(51.9%)of cases in the adenoma group and in 46/60(76.7%)of cases in the cancer group(P=0.006).Ulceration of the mucosal surface on endoscopy was found in 5(9.6%)of 52 lesions in the adenoma group and in 17(28.3%)of 60 lesions in the cancer group(P=0.013).In the multivariate analysis,a reddish surface color change and mucosal ulceration were significant predictive factors correlated with cancer after ESD of the HGN by forceps biopsy.CONCLUSION:HGN with a red color change or mucosal ulceration correlated with the presence of gastric cancer.These finding may help to guide the diagnosis and treatment. | Jung Ho Kim Yoon Jae Kim Jungsuk An Jong Joon Lee Jae Hee Cho Kyoung Oh Kim Jun-Won Chung Kwang An Kwon Dong Kyun Park Ju Hyun Kim | 2014 | World Journal of Gastroenterology2014，20，34： | 10 |
| 3 | Gastric leptomeningeal carcinomatosis: Multi-center retrospective analysis of 54 cases显示文摘AIM: To identify the clinical features and outcomes of infrequently reported leptomeningeal carcinomatosis (LMC) of gastric cancer.METHODS: We analyzed 54 cases of cytologically confirmed gastric LMC at four institutions from 1994 to 2007.RESULTS: The male-to-female ratio was 32:22, and the patients ranged in age from 28 to 78 years (median,48.5 years). The majority of patients had advanced disease at initial diagnosis of gastric cancer. The clini-cal or pathologic tumor, node and metastasis stage ofthe primary gastric cancer wasin 38 patients (70%).The median interval from diagnosis of the primarymalignancy to the diagnosis of LMC was 6.3 mo, rang-ing between 0 and 73.1 mo. Of the initial endoscopic f indings for the 45 available patients, 23 (51%) of the patients were Bormann typeand 15 (33%) patientswere Bormann type. Pathologically, 94% of cases proved to be poorly differentiated adenocarcinomas. Signet ring cell component was also observed in 40% of patients. Headache (85%) and nausea/vomiting (58%) were the most common presenting symptoms of LMC. A gadolinium-enhanced magnetic resonance imaging was conducted in 51 patients. Leptomeningeal enhancement was noted in 45 cases (82%). Intrathecal (IT) chemotherapy was administered to 36 patients-primarily methotrexate alone (61%), but also in combi-nation with hydrocortisone/± Ara-C (39%). The median number of IT treatments was 7 (range, 1-18). Concomitant radiotherapy was administered to 18 patients, and concomitant chemotherapy to seven patients. Sev-enteen patients (46%) achieved cytological negative conversion. Median overall survival duration from the diagnosis of LMC was 6.7 wk (95% CI: 4.3-9.1 wk). In the univariate analysis of survival duration, hemoglobin, IT chemotherapy, and cytological negative conversion showed superior survival duration (P = 0.038, P = 0.010, and P = 0.002, respectively). However, in our multivariate analysis, only cytological negative conversion was predictive of relatively longer survival duration (3.6, 6.7 and 14.6 wk, P = 0.030, RR: 0.415, 95% CI: 0.188-0.918).CONCLUSION: Although these patients had a fatal clinical course, cytologic negative conversion by IT chemotherapy may improve survival. | Sung Yong Oh Su-Jin Lee Jeeyun Lee Suee Lee Sung-Hyun Kim Hyuk-Chan Kwon Gyeong-Won Lee Jung Hun Kang In Gyu Hwang Joung-Soon Jang Ho Yeong Lim Young Suk Park Won Ki Kang Hyo-Jin Kim | 2009 | World Journal of Gastroenterology2009，15，40： | 10 |
| 4 | Dual-priming oligonucleotide-based multiplex PCR using tissue samples in rapid urease test in the detection of Helicobacter pylori infection显示文摘AIM:To investigate whether tissue samples processed by the rapid urease test(RUT)kit are suitable for dualpriming oligonucleotide-based multiplex polymerase chain reaction(DPO-PCR)to detect Helicobacter pylori(H.pylori).METHODS:A total of 54 patients with specific gastrointestinal symptom were enrolled in this study.During endoscopy,gastric biopsy specimens were taken for histology,RUT,and DPO-PCR.DPO-PCR was performed on gastric biopsy samples and tissue samples that were analyzed by RUT at 2 separate institutes.In detecting H.pylori,the concordance rate of the DPO-PCR tests between the tissue samples that had been submitted to RUT and the gastric biopsy samples was investigated.RESULTS:H.pylori co-occurred with 76.0%(19/25)of gastric ulcers,64.3%(9/14)of duodenal ulcers,and 33.3%(4/12)of gastritis cases.H.pylori infection was found in 100%(3/3)of the patients with both gastric and duodenal ulcers.Overall,H.pylori was detected in 35 of 54(64.8%)patients.The diagnostic sensitivities of histology,RUT,and DPO-PCR were85.7%(30/35),74.3%(26/35),and 97.1%(34/35),respectively(P=0.02).The positive predictive value(PPV)of DPO-PCR was 94.4%,whereas the negative predictive value(NPV)was 94.7%.In the rapid urease test(CLOtest)-negative cases,the frequency of positive DPO-PCR and histologic results was 20.0%(7/35).The concordance rate of the DPO-PCR tests between the tissue samples from the RUT kit and the gastric biopsy samples was 94.4%(51/54).The rate of DPOPCR and silver stain positivity in the RUT-negative cases was 20.0%(7/35).CONCLUSION:In diagnosing H.pylori infection,DPO-PCR can be performed on tissue samples that have been processed by the RUT kit.Particularly,in patients with RUT-negative results,DPO-PCR on these tissue samples could be helpful in detecting of H.pylori infection. | Woo Chul Chung Sung Hoon Jung Jung Hwan Oh Tae Ho Kim Dae Young Cheung Byung Wook Kim Sung Soo Kim Jin Il Kim Eun Young Sin | 2014 | World Journal of Gastroenterology2014，20，21： | 10 |
| 5 | Recurrent massive bleeding due to dissecting intramural hematoma of the esophagus: Treatment with therapeutic angiography显示文摘Spontaneous or traumatic intramural bleeding of the esophagus, which is often associated with overlying mucosal dissection, constitutes a rare spectrum of esophageal injury called dissecting intramural hematoma of the esophagus (DIHE). Chest pain, swallowing diffi culty, and minor hematemesis are common, which resolve spontaneously in most cases. This case report describes a patient with spontaneous DIHE with recurrent massive bleeding which required critical management and highlights a potential role for therapeutic angiography as an alternative to surgery. | Jaejun Shim Jae Young Jang Young Hwangbo Seok Ho Dong Joo Hyeong Oh Hyo Jong Kim Byung-Ho Kim Young Woon Chang Rin Chang | 2009 | World Journal of Gastroenterology2009，15，41： | 8 |
| 6 | Predictors of poor outcomes in patients with wild mushroom-induced acute liver injury显示文摘AIM To identify early predictive markers of poor outcomes in patients with acute liver injury from wild mushroom intoxication.METHODS This observational, retrospective record review involved adults aged ≥ 18 years admitted to emergency department with mushroom intoxication from January 2005 to December 2015. The diagnosis of mushroom intoxication was based on the following:(1) a positive history of recent wild mushroom intake(either raw or cooked);(2) the onset of gastrointestinal symptoms, such as watery diarrhea, vomiting, and/or abdominal pain, after ingestion; and(3) the exclusion of other possible causes of acute liver injury. Acute liver injury was defined by a > 5-fold elevation of liver enzymes or moderate coagulopathy [international normalized ratio(INR) > 2.0]. Clinical and laboratory findings were compared in survivors and non-survivors.RESULTS Of 93 patients with mushroom intoxication, 23, 11 men(47.8%) and 12 women(52.2%), of median age 61 years, developed acute liver injury. The overall inhospital mortality rate was 43.5%(10/23). Among thelaboratory variables, mean serum alkaline phosphatase(73.38 ± 10.89 mg/dL vs 180.40 ± 65.39 mg/dL, P < 0.01), total bilirubin(2.312 ± 1.16 mg/dL vs 7.16 ± 2.94 mg/d L, P < 0.01) concentrations and indirect/direct bilirubin(2.45 ± 1.39 mg/dL vs 0.99 ± 0.45 mg/dL, P < 0.01) ratio as well as prothrombin time(1.88 ± 0.83 mg/dL vs 10.43 ± 4.81 mg/dL, P < 0.01), and activated partial thromboplastin time(a PTT; 32.48 ± 7.64 s vs 72.58 ± 41.29 s, P = 0.01), were significantly higher in non-survivors than in survivors. Logistic regression analysis showed that total bilirubin concentration(OR = 3.58, 95%CI: 1.25-10.22), indirect/direct bilirubin ratio(OR = 0.14, 95%CI: 0.02-0.94) and aP TT(OR = 1.30, 95%CI: 1.04-1.63) were significantly associated with mortality. All patients with total bilirubin > 5 mg/dL or aP TT > 50 s on day 3 died.CONCLUSION Monitoring of bilirubin concentrations and a PTT may help in predicting clinical outcomes in patients with acute liver injury from wild mushroom intoxication. | Taerim Kim Danbi Lee Jae Ho Lee Yoon-Seon Lee Bum Jin Oh Kyoung Soo Lim Won Young Kim | 2017 | World Journal of Gastroenterology2017，23，7： | 7 |
| 7 | Effects of Bacillus subtilis CSL2 on the composition and functional diversity of the faecal microbiota of broiler chickens challenged with Salmonella Gallinarum显示文摘Background: The chicken gastrointestinal tract contains a diverse microbiota whose composition and structure play important roles in gut functionality. In this study, microbial shifts resulting from feed supplementation with Bacillus subtilis CSL2 were evaluated in broilers challenged and unchallenged with Salmonella Gallinarum. To analyse bacterial community composition and functionality, 454 GS-FLX pyrosequencing of 16 S r RNA gene amplicons was performed.Results: The Quantitative Insights into Microbial Ecology(QIIME) pipeline was used to analyse changes in the faecal microbiota over a 24-h period. A total of 718,204 sequences from broiler chickens were recorded and analysed. At the phylum level, Firmicutes, Bacteroidetes, and Proteobacteria were the predominant bacterial taxa. In Salmonellainfected chickens(SC), Bacteroidetes were more highly abundant compared to control(NC) and Bacillus-treated(BT)chickens. At the genus level, in the NC and BT groups, Lactobacil us was present at high abundance, and the abundance of Turicibacter, unclassified Enterobacteriaceae, and Bacteroides increased in SC broilers. Furthermore, taxon-independent analysis showed that the SC and BT groups were compositional y distinct at the end of the 24-h period. Further analysis of functional properties showed that B. subtilis CSL2 administration increased gut-associated energy supply mechanisms(i.e. carbohydrate transport and metabolism) to maintain a stable microbiota and protect gut integrity.Conclusions: This study demonstrated that S. Gallinarum infection and B. subtilis CSL2 supplementation in the diet of broiler chickens influenced the diversity, composition, and functional diversity of the faecal microbiota. Moreover, the findings offer significant insights to understand potential mechanisms of Salmonel a infection and the mode of action of probiotics in broiler chickens. | Ju Kyoung Oh Edward Alain B.Pajarillo Jong Pyo Chae In Ho Kim Dong Soo Yang Dae-Kyung Kang | 2017 | Journal of Animal Science and Biotechnology2017，8，2： | 6 |

| 9 | 4-1BB signaling activates glucose and fatty acid metabolism to enhance CD8^(+) T cell proliferation显示文摘4-1BB(CD137)is a strong enhancer of the proliferation of CD8^(+)T cells.Since these cells require increased production of energy and biomass to support their proliferation,we hypothesized that 4-1BB signaling activated glucose and fatty acid metabolism.We found that treatment with agonistic anti-4-1BB mAb promoted the proliferation of CD8^(+)T cells in vitro,increasing their size and granularity.Studies with a glycolysis inhibitor and a fatty acid oxidation inhibitor revealed that CD8^(+)T cell proliferation required both glucose and fatty acid metabolism.Anti-4-1BB treatment increased glucose transporter 1 expression and activated the liver kinase B1(LKB1)-AMP-activated protein kinase(AMPK)-acetyl-CoA carboxylase(ACC)signaling pathway,which may be responsible for activating the metabolism of glucose and fatty acids.We also examined whether blocking glucose or fatty acid metabolism affected cell cycle progression and the anti-apoptotic effect of 4-1BB signaling.The increase of anti-apoptotic factors and cyclins in response to anti-4-1BB treatment was completely prevented by treating CD8^(+)T cells with the fatty acid oxidation inhibitor,etomoxir,but not with the glycolysis inhibitor,2-deoxy-D-glucose.We conclude that anti-4-1BB treatment activates glucose and fatty acid metabolism thus supporting the increased demand for energy and biomass,and that fatty acid metabolism plays a crucial role in enhancing the cell cycle progression of anti-CD3-activated CD8^(+)T cells in vitro and the anti-apoptotic effects of 4-1BB signaling on these cells. | Beom K Choi Do Y Lee Don G Lee Young H Kim Seon-Hee Kim Ho S Oh Chungyong Han Byoung S Kwon | 2017 | Cellular & Molecular Immunology2017，14，9： | 6 |
| 10 | Hepatic arterial infusion chemotherapy in hepatocellular carcinoma with portal vein tumor thrombosis显示文摘AIM: To evaluate the prognostic factors and efficacy of hepatic arterial infusion chemotherapy in hepatocellular carcinoma with portal vein tumor thrombosis. METHODS: Fifty hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) were treated using hepatic arterial infusion chemotherapy (HAIC) via a subcutaneously implanted port. The epirubicin-cisplatin-5-fluorouracil (ECF) chemotherapeutic regimen consisted of 35 mg/m 2 epirubicin on day 1, 60 mg/m 2 cisplatin for 2 h on day 2, and 500 mg/m 2 5-fluorouracil for 5 h on days 1-3. The treatments were repeated every 3 or 4 wk. RESULTS: Three (6%) of the 50 patients achieved a complete response (CR), 13 (26%) showed partial responses (PR), and 22 (44%) had stable disease (SD).The median survival and time to progression were 7 and 2 mo, respectively. After 2 cycles of HAIC, CR was achieved in 1 patient (2%), PR in 10 patients (20%) and SD in 26 patients (52%). Significant pre-treatment prognostic factors were a tumor volume of < 400 cm 3 (P = 0.01) and normal levels of protein induced by vitamin K absence or antagonist (PIVKA)-Ⅱ (P = 0.022). After 2 cycles of treatment, disease control (CR + PR + SD) (P = 0.001), PVTT response (P = 0.003) and α-fetoprotein reduction of over 50% (P = 0.02) were independent factors for survival. Objective response (CR + PR), disease control, PVTT response, and combination therapy during the HAIC were also significant prognostic factors. Adverse events were tolerable and successfully managed. CONCLUSION: HAIC may be an effective treatment modality for advanced HCC with PVTT in patients with tumors < 400 cm 3 and good prognostic factors. | Do Seon Song Si Hyun Bae Myeong Jun Song Sung Won Lee Hee Yeon Kim Young Joon Lee Jung Suk Oh Ho Jong Chun Hae Giu Lee Jong Young Choi Seung Kew Yoon | 2013 | World Journal of Gastroenterology2013，19，29： | 5 |
| 11 | Association between hepatocellular carcinoma and tumor necrosis factor alpha polymorphisms in South Korea显示文摘AIM: To investigate associations between the tumor necrosis factor alpha(TNF-α)-1031 T>C,-863 C>A,-857 C>T,-308 G>A,and-238 G>A polymorphisms and HCC in Korea.METHODS: Hepatocellular carcinoma(HCC) cases were diagnosed at CHA Bundang Medical Center from June 1996 to August 2008. The association between TNF-α polymorphisms and HCC was analyzed in 157HCC patients and 201 controls using a polymerase chain reaction-restriction fragment length polymorphism assay. We investigated five TNF-α polymorphisms,which are TNF-α-1031 T>C,-863 C>A,-857 C>T,-308 G>A,and-238 G>A. The TNF-α genotype frequencies,genotype combinations and haplotypes were analyzed to disclose the association with HCC.RESULTS: None of the TNF-α polymorphisms was significantly associated with HCC. However,nine genotype combinations had associations with increased likelihood of HCC. Among them,TNF-α-1031/-857/-238 TT/CC/GA(AOR = 18.849,95%CI: 2.203-161.246,P = 0.007),TNF-α-1031/-308/-238 TT/GG/GA(AOR = 26.956,95%CI: 3.071-236.584,P = 0.003),and TNF-α-1031/-238 TT/GA(AOR = 21.576,95%CI: 2.581-180.394,P = 0.005) showed marked association with HCC. There were five haplotypes of TNF-α polymorphisms which were significantly associated with HCC. They are TNF-α-1031/-863/-857/-308/-238 T-C-C-G-A(OR = 25.824,95%CI: 1.491-447.223,P = 0.0005),TNF-α-1031/-857/-308/-238 T-C-G-A(OR = 12.059,95%CI: 2.747-52.950,P < 0.0001),TNF-α-1031/-857/-238 T-C-A(OR = 10.696,95%CI: 2.428-47.110,P = 0.0001),TNF-α-1031/-308/-238 T-G-A(OR = 7.556,95%CI: 2.173-26.280,P = 0.0002) and TNF-α-1031/-238 T-A(OR = 10.865,95%CI: 2.473-47.740,P = 0.0001). Moreover,HCC Okuda stage Ⅲ cases with the TNF-α-1031 CC genotype had better survival than those with the TT genotype(AOR = 5.795,95%CI: 1.145-29.323). CONCLUSION: Although no single TNF-α polymorphism is associated with HCC in this study,some TNF-α genotype combinations and haplotypes are associated with HCC. In addition,HCC Okuda stage Ⅲ cases with the TNF-α-1031 TT genotype may have a better prognosis than those with the CC genotype. | Suk Pyo Shin Nam Keun Kim Ju Hwan Kim Ju Ho Lee Jung Oh Kim Sung Hwan Cho Hana Park Mi Na Kim Kyu Sung Rim Seong Gyu Hwang | 2015 | World Journal of Gastroenterology2015，21，46： | 5 |

| 13 | Surgical failure after colonic stenting as a bridge to surgery显示文摘AIM: To identify risk factors for surgical failure after colonic stenting as a bridge to surgery in left-sided malignant colonic obstruction.METHODS: The medical records of patients who underwent stent insertion for malignant colonic obstruction between February 2004 and August 2012 were retrospectively reviewed. Patients with malignant colonic obstruction had overt clinical symptoms and signs of obstruction. Malignant colonic obstruction was diagnosed by computed tomography and colonoscopy. A total of 181 patients underwent stent insertion during the study period; of these, 68 consecutive patientswere included in our study when they had undergone stent placement as a bridge to surgery in acute leftsided malignant colonic obstruction due to primary colon cancer.RESULTS: Out of 68 patients, forty-eight(70.6%) were male, and the mean age was 64.9(range, 38-89) years. The technical and clinical success rates were 97.1%(66/68) and 88.2%(60/68), respectively. Overall, 85.3%(58/68) of patients underwent primary tumor resection and primary anastomosis. Surgically successful preoperative colonic stenting was achieved in 77.9%(53/68). The mean duration, defined as the time between the SEMS attempt and surgery, was 11.3 d(range, 0-26 d). The mean hospital stay after surgery was 12.5 d(range, 6-55 d). On multivariate analysis, the use of multiple self-expanding metal stents(OR = 28.872; 95%CI: 1.939-429.956, P = 0.015) was a significant independent risk factor for surgical failure of preoperative stenting as a bridge to surgery. Morbidity and mortality rates in surgery after stent insertion were 4.4%(3/68) and 1.5%(1/68), respectively.CONCLUSION: The use of multiple self-expanding metal stents appears to be a risk factor for surgical failure. | Jung Ho Kim Kwang An Kwon Jong Joon Lee Won-Suk Lee Jeong-Heum Baek Yoon Jae Kim Jun-Won Chung Kyoung Oh Kim Dong Kyun Park Ju Hyun Kim | 2014 | World Journal of Gastroenterology2014，20，33： | 5 |

| 18 | Endoscopic stenting for recurrence-related colorectal anastomotic site obstruction:Preliminary experience显示文摘AIM:To evaluate the efficacy of stents in treating patients with anastomotic site obstructions due to cancer recurrence following colorectal surgery.METHODS:The medical records of patients who underwent endoscopic self-expanding metal stents(SEMS)insertion for colorectal obstructions between February2004 and January 2014 were retrospectively reviewed.During the study period,a total of 218 patients underwent endoscopic stenting for colorectal obstructions.We identified and examined the patients who underwent endoscopic stenting for obstructions caused by cancer recurrence at the anastomotic site following colorectal surgeries for primary colorectal cancer.RESULTS:Five consecutive patients[mean age,56.4years(range:39-82 years);4 women,1 man]underwent endoscopic stenting for obstructions caused by cancer recurrence at the anastomotic site following colorectal surgeries for primary colorectal cancer.Technical and clinical success was achieved in all 5 patients,without any early complications.During follow-up,3patients did not need further intervention,prior to their death,after the first stent insertion;thus,the overall success rate was 3/5(60%).Perforations occurred in 2patients who required a second SEMS insertion due to re-obstruction;none of the patients experienced stent migration.CONCLUSION:SEMS placement is a promising treatment option for patients who develop obstructions of their colonic anastomosis sites due to cancer recurrence. | Jung Ho Kim Jong Joon Lee Jae Hee Cho Kyoung Oh Kim Jun-Won Chung Yoon Jae Kim Kwang An Kwon Dong Kyun Park Ju Hyun Kim | 2014 | World Journal of Gastroenterology2014，20，38： | 4 |
| 19 | Gender differences in clinical outcomes of acute myocardial infarction undergoing percutaneous coronary intervention: insights from the KAMIR-NIH Registry显示文摘Background There are numerous but conflicting data regarding gender differences in outcomes following percutaneous coronary intervention(PCI). Furthermore, gender differences in clinical outcomes with acute myocardial infarction(AMI) following PCI in Asian population remain uncertain because of the under-representation of Asian in previous trials. Methods A total of 13,104 AMI patients from Korea Acute Myocardial Infarction Registry-National Institute of Health(KAMIR-NIH) between November 2011 and December 2015 were classified into male(n = 8021, 75.9%) and female(n = 2547, 24.1%). We compared the demographic, clinical and angiographic characteristics, 30-days and 1-year major adverse cardiac and cerebrovascular events(MACCE) in women with those in men after AMI by using propensity score(PS) matching. Results Compared with men, women were older, had more comorbidities and more often presented with non-ST segment elevation myocardial infarction(NSTEMI) and reduced left ventricular systolic function. Over the median follow-up of 363 days, gender differences in both 30-days and 1-year MACCE as well as thrombolysis in myocardial infarction minor bleeding risk were not observed in the PS matched population(30-days MACCE: 5.3% vs. 4.7%, log-rank P = 0.494, HR = 1.126, 95% CI: 0.800-1.585;1-year MACCE: 9.3% vs. 9.0%, log-rank P = 0.803, HR = 1.032, 95% CI: 0.802-1.328;TIMI minor bleeding: 4.9% vs. 3.9%, log-rank P = 0.215, HR = 1.255, 95% CI: 0.869-1.814). Conclusions Among Korean AMI population undergoing contemporary PCI, women, as compared with men, had different clinical and angiographic characteristics but showed similar 30-days and 1-year clinical outcomes. The risk of bleeding after PCI was comparable between men and women during one-year follow up. | Myunhee Lee Dae-Won Kim Mahn-Won Park Kyusup Lee Kiyuk Chang Wook Sung Chung Tae Hoon Ahn Myung Ho Jeong Seung-Woon Rha Hyo-Soo Kim Hyeon Cheol Gwon In Whan Seong Kyung Kuk Hwang Shung Chull Chae Kwon-Bae Kim Young Jo Kim Kwang Soo Cha Seok Kyu Oh Jei Keon Chae Ji-Hoon Jung 无 KAMIR-NIH registry investigators | 2020 | Journal of Geriatric Cardiology2020，17，11： | 3 |
| 20 | Bevacizumab as a second- or later-line of treatment for metastatic colorectal cancer显示文摘AIM: To determine the efficacy of bevacizumab in patients with metastatic colorectal cancer (MCRC) who have failed prior chemotherapy without bevacizumab. METHODS: Between March 2002 and June 2010, 40 patients in South Korea with MCRC who were treated with bevacizumab plus chemotherapy as a second or later-line treatment were analyzed retrospectively for their overall response rate (ORR), overall survival (OS), and progression-free survival (PFS). The tumor responses were assessed using the RECIST (Response Evaluation Criteria in Solid Tumors) guidelines. RESULTS: All of the patients had progressed under prior chemotherapy without bevacizumab. Three patients (7.5%) exhibited an ORR, twenty one patients (52.5%) exhibited stable disease (SD), and fifteen patients (37.5%) exhibited disease progression. The median duration of the OS and PFS were 14.0 and 6.13 mo respectively. The median OSs were 16.60, 14.07 and 13.00 mo for second-line, third-line and fourth- or later-line treatments, respectively. The median PFSs were 7.23, 7.30 and 3.87 mo for the second-line, third-line and fourth- or later-line treatments, respectively. CONCLUSION: In patients with MCRC, bevacizumab combined chemotherapy may be beneficial during second- or later-line treatment. | Lee Chun Park Ho Sup Lee Seong Hoon Shin Seun Ja Park Moo In Park Sung Yong Oh Hyuk Chan Kwon Jin ho Baek Young Jin Choi Myoung Joo Kang Yang Soo Kim | 2012 | World Journal of Gastroenterology2012，18，10： | 3 |
