| 5 | Pretreated quercetin protects gerbil hippocampal CA1 pyramidal neurons from transient cerebral ischemic injury by increasing the expression of antioxidant enzymes显示文摘Quercetin(QE; 3,5,7,3′,4′-pentahydroxyflavone), a well-known flavonoid, has been shown to prevent against neurodegenerative disorders and ischemic insults. However, few studies are reported regarding the neuroprotective mechanisms of QE after ischemic insults. Therefore, in this study, we investigated the effects of QE on ischemic injury and the expression of antioxidant enzymes in the hippocampal CA1 region of gerbils subjected to 5 minutes of transient cerebral ischemia. QE was pre-treated once daily for 15 days before ischemia. Pretreatment with QE protected hippocampal CA1 pyramidal neurons from ischemic injury, which was confirmed by neuronal nuclear antigen immunohistochemistry and Fluoro-Jade B histofluorescence staining. In addition, pretreatment with QE significantly increased the expression levels of endogenous antioxidant enzymes Cu/Zn superoxide dismutase, Mn superoxide dismutase, catalase and glutathione peroxidase in the hippocampal CA1 pyramidal neurons of animals with ischemic injury. These findings demonstrate that pretreated QE displayed strong neuroprotective effects against transient cerebral ischemia by increasing the expression of antioxidant enzymes. | Bai Hui Chen Joon Ha Park Ji Hyeon Ahn Jeong Hwi Cho In Hye Kim Jae Chul Lee Moo-Ho Won Choong-Hyun Lee In Koo Hwang Jong-Dai Kim Il Jun Kang Jun Hwi Cho Bich Na Shin Yang Hee Kim Yun Lyul Lee Seung Min Park | 2017 | Neural Regeneration Research2017，12，2： | 9 |
| 6 | Retrospective analysis of extra-gastrointestinal stromal tumors显示文摘AIM:To investigate the clinicopathologic features of patients with extra-gastrointestinal stromal tumors(EGISTs)in South Korea.METHODS:A total of 51 patients with an EGIST were identified.The clinicopathologic features,including sex,age,location,tumor size,histology,mitotic rate,immunohistochemical features,genetic status and survival data,were analyzed.RESULTS:The median age was 55 years(range:29-80years),and male:female ratio was 1:1.04.The most common site was in the mesentery(n=15)followed by the retroperitoneum(n=13)and omentum(n=8).The median tumor size was 9.0 cm(range:2.6-30.0cm)and the median mitotic rate was 5.0/50HPF.(1/50-185/50).KIT was analyzed in 16,which revealed 10cases with wild-type KIT and 6 cases with an exon 11mutation.Among 51 patients,31 patients had undergone surgery,and 10 had unresectable disease and had taken palliative imatinib,which resulted in 22.7 mo of progression-free survival.Of the patients who had undergone surgery,18 did not take adjuvant imatinib,and 8 of these were categorized as'high risk'according to the risk criteria.However,the relapse-free survival was not different(P=0.157)between two groups.CONCLUSION:Because the biologic behaviors of GISTs differ according to the location of the tumor,a more stratified strategy is required for managing EGISTs including incorporation of molecular features. | Jun Ho Yi Byeong-Bae Park Jung Hun Kang In Gyu Hwang Dong Bok Shin Sun Jin Sym Hee Kyung Ahn Soon Il Lee Do Hyoung Lim Keon Woo Park Young-Woong Won Sung Hee Lim Se Hoon Park | 2015 | World Journal of Gastroenterology2015，21，6： | 9 |
| 7 | Quality of survival in patients treated for malignant biliary obstruction caused by unresectable pancreatic head cancer: surgical versus non-surgical palliation显示文摘BACKGROUND:Appropriate palliation for unresectable pancreatic head cancer is most important.This study was undertaken to compare the survival of patients with biliary obstruction caused by unresectable pancreatic head cancer after surgical and non-surgical palliation. METHODS:We retrospectively reviewed 69 patients who underwent palliative treatment for unresectable pancreatic head cancer.Fifty-two patients with locally advanced disease (local vascular invasion)and 17 with distant metastatic disease were included.The patients were divided into two groups,surgical and non-surgical palliation. RESULTS:Thirty-eight patients underwent biliary bypass surgery and 31 had percutaneous transhepatic biliary drainage(PTBD).There was no significant difference in the early complications,successful biliary drainage, recurrent jaundice,and 30-day mortality between surgical palliation and PTBD.However,in 52 patients whose tumor was unresectable secondary to local vascular invasion,the rate of recurrent jaundice after successful surgical biliary palliation was lower than that in patients who had non- surgical palliation(P<0.05).The patients who underwent surgical palliation had a longer hospital-free survival rate(P<0.001),although they had a longer postoperative hospital stay(P=0.004)during the first admission period.CONCLUSIONS:In patients with preoperative evaluations showing potentially resectable tumors and/or no metastatic lesions,surgical exploration should be performed.Thus,in patients who have unresectable cancer or limited metastatic disease on exploration,surgical palliation should be performed for longer survival and better quality of survival. | Hyung Ook Kim Sang Il Hwang Hungdai Kim Jun Ho Shin | 2008 | Hepatobiliary & Pancreatic Diseases International2008，7，6： | 8 |
| 8 | Optimal initiation of Helicobacter pylori eradication in patients with peptic ulcer bleeding显示文摘AIM:To evaluate when Helicobacter pylori(H.pylori)eradication therapy(ET)should be started in patients with peptic ulcer bleeding(PUB).METHODS:Clinical data concerning adults hospitalizedwith PUB were retrospectively collected and analyzed.Age,sex,type and stage of peptic ulcer,whether endoscopic therapy was performed or not,methods of H.pylori detection,duration of hospitalization,and specialty of the attending physician were investigated.Factors influencing the confirmation of H.pylori infection prior to discharge were determined using multiple logistic regression analysis.The H.pylori eradication rates of patients who received ET during hospitalization and those who commenced ET as outpatients were compared.RESULTS:A total of 232 patients with PUB were evaluated for H.pylori infection by histology and/or rapid urease testing.Of these patients,53.7%(127/232)had confirmed results of H.pylori infection prior to discharge.In multivariate analysis,duration of hospitalization and ulcer stage were factors independently influencing whether H.pylori infection was confirmed before or after discharge.Among the patients discharged before confirmation of H.pylori infection,13.3%(14/105)were lost to follow-up.Among the patients found to be H.pylori-positive after discharge,41.4%(12/29)did not receive ET.There was no significant difference in the H.pylori eradication rate between patients who received ET during hospitalization a n d t h o s e w h o c o m m e n c e d E T a s o u t p a t i e n t s[intention-to-treat:68.8%(53/77)vs 60%(12/20),P=0.594;per-protocol:82.8%(53/64)vs 80%(12/15),P=0.723].CONCLUSION:Because many patients with PUB who were discharged before H.pylori infection status was confirmed lost an opportunity to receive ET,we should confirm H.pylori infection and start ET prior to discharge. | Hyuk Yoon Dong Ho Lee Eun Sun Jang Jaihwan Kim Cheol Min Shin Young Soo Park Jin-Hyeok Hwang Jin-Wook Kim Sook-Hayng Jeong Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，8： | 7 |
| 9 | Pre-operative predictive factors for gallbladder cholesterol polyps using conventional diagnostic imaging显示文摘AIM:To determine the clinical data that might be useful for differentiating benign from malignant gallbladder (GB) polyps by comparing radiological methods,including abdominal ultrasonography (US) and computed tomography (CT) scanning,with postoperative pathology fi ndings. METHODS:Fifty-nine patients underwent laparoscopic cholecystectomy for a GB polyp of around 10 mm. They were divided into two groups,one with cholesterol polyps and the other with non-cholesterol polyps. Clinical features such as gender,age,symptoms,size and number of polyps,the presence of a GB stone,the radiologically measured maximum diameter of the polyp by US and CT scanning,and the measurements of diameter from postoperative pathology were recorded for comparative analysis. RESULTS:Fifteen of the 41 cases with cholesterol polyps (36.6%) were detected with US but not CT scanning,whereas all 18 non-cholesterol polyps were observed using both methods. In the cholesterol polyp group,the maximum measured diameter of the polyp was smaller by CT scan than by US.Consequently,the discrepancy between those two scanning measurements was greater than for the non-cholesterol polyp group. CONCLUSION:The clinical signs indicative of a cholesterol polyp include:(1) a polyp observed by US but not observable by CT scanning,(2) a smaller diameter on the CT scan compared to US,and (3) a discrepancy in its maximum diameter between US and CT measurements. In addition,US and the CT scan had low accuracy in predicting the polyp diameter compared to that determined by postoperative pathology. | Ji-Hoon Choi Jung-Won Yun Yong-Sung Kim Eun-A Lee Sang-Tae Hwang Yong-Kyun Cho Hong-Joo Kim Jung-Ho Park Dong-Il Park Chong-Il Sohn Woo-Kyu Jeon Byung-Ik Kim Hyoung-Ook Kim Jun-Ho Shin | 2008 | World Journal of Gastroenterology2008，14，44： | 7 |

| 11 | Pretreated Oenan the Javanica extract increases anti-inflammatory cytokines, attenuates gliosis, and protects hippocampal neurons following transient global cerebral ischemia in gerbils显示文摘Recently,we have reported that Oenanthe javanica extract(OJE)displays strong neuroprotective effect against ischemic damage after transient global cerebral ischemia.However,neuroprotective mechanisms of OJE have not been fully identified.Thus,this study investigated the neuroprotection of OJE in the hippocampal CA1 area and its anti-inflammatory activity in gerbils subjected to 5 minutes of transient global cerebral ischemia.We treated the animals by intragastrical injection of OJE(100 and 200 mg/kg)once daily for 1 week prior to transient global cerebral ischemia.Neuroprotection of OJE was observed by immunohistochemistry for neuronal nuclear antigen and histofluorescence staining for Fluoro-Jade B.Immunohistochemistry of glial fibrillary acidic protein and ionized calcium-binding adapter molecule 1 was done for astrocytosis and microgliosis,respectively.To investigate the neuroprotective mechanisms of OJE,we performed immunohistochemistry of tumor necrosis factor-alpha and interleukin-2 for pro-inflammatory function and interleukin-4 and interleukin-13 for anti-inflammatory function.When we treated the animals by intragastrical administration of 200 mg/kg of OJE,hippocampal CA1 pyramidal neurons were protected from transient global cerebral ischemia and cerebral ischemia-induced gliosis was inhibited in the ischemic hippocampal CA1 area.We also found that interleukin-4 and-13 immunoreactivities were significantly increased in pyramidal neurons of the ischemic CA1 area after OJE pretreatment,and the increased immunoreactivities were sustained in the CA1 pyramidal neurons after transient global cerebral ischemia.However,OJE pretreatment did not increase interleukin-2 and tumor necrosis factor-alpha immunoreactivities in the CA1 pyramidal neurons.Our findings suggest that pretreatment with OJE can protect neurons and attenuate gliosis from transient global cerebral ischemia via increasing expressions of interleukin-4 and-13.The experimental plan of this study was reviewed and approved by the Institutional Animal Care and Use Committee(IACUC)in Kangwon National University(approval No.KW-160802-1)on August 10,2016. | Joon Ha Park In Hye Kim Ji Hyeon Ahn YooHun Noh Sung-Su Kim Tae-Kyeong Lee Jae-Chul Lee Bich-Na Shin Tae Heung Sim Hyun Sam Lee Jeong Hwi Cho In Koo Hwang Il Jun Kang Jong Dai Kim Moo-Ho Won | 2019 | Neural Regeneration Research2019，14，9： | 6 |

| 13 | 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 |
| 14 | Outcome of laparoscopic cholecystectomy is not influenced by chronological age in the elderly显示文摘AIM:To evaluate the outcome of laparoscopic cholecystectomy(LC)in patients aged 80 years and older. METHODS:A total of 353 patients aged 65 to 79 years(group 1)and 35 patients aged 80 years and older(group 2)underwent LC.Patients were further classified into two other groups:those with uncomplicated gallbladder disease(group A)or those with complicated gallbladder disease(group B). RESULTS:There were no significant differences between the age groups(groups 1 and 2)with respect to clinical characteristics such as age,gender,comorbid disease,or disease presentation.Mean operative time,conversion rate,and the incidence of major postoperative complications were similar in groups 1 and 2.However,the percentage of high-risk patients was significantly higher in group 2 than in group 1 (20.0%vs 5.7%,P<0.01).Group A comprised 322 patients with a mean age of 71.0±5.3 years,and group B comprised 51 patients with a mean age of 69.9±4.8 years.In group B,mean operative time (78.4±49.3 min vs 58.3±35.8 min,P<0.01),mean postoperative hospital stay(7.9±6.5 d vs 5.0±3.7 d, P<0.01),and the incidence of major postoperative complications(9.8%vs 3.1%,P<0.05)were significantly greater than in group A.The conversion rate tended to be higher in group B,but this difference was not significant. CONCLUSION:Perioperative outcomes in elderly patients who underwent LC seem to be influenced by the severity of gallbladder disease,and not by chronologic age.In octogenarians,LC should be performed at an earlier,uncomplicated stage of the disease whenever possible to improve perioperative outcomes. | Hyung Ook Kim Jung Won Yun Jun Ho Shin Sang Il Hwang Yong Kyun Cho Byung Ho Son Chang Hak Yoo Yong Lai Park Hungdai Kim | 2009 | World Journal of Gastroenterology2009，15，6： | 5 |
| 15 | Eradication rate and histological changes after Helicobacter pylori eradication treatment in gastric cancer patients following subtotal gastrectomy显示文摘AIM: To investigate the eradication rate and histological changes after Helicobacter pylori(H. pylori) eradication treatment following subtotal gastrectomy for gastric cancer.METHODS: A total of 610 patients with H. pylori infection who had undergone surgery for either early or advanced gastric adenocarcinoma between May 2004 and December 2010 were retrospectively studied. A total of 584 patients with proven H. pylori infection after surgery for gastric cancer were enrolled in this study. Patients received a seven day standard triple regimen as first-line therapy and a 10 d bismuthcontaining quadruple regimen as second-line therapy in cases of eradication failure. The patients underwent an esophagogastroduodenoscopy(EGD) between six and 12 mo after surgery, followed by annual EGDs. A further EGD was conducted 12 mo after confirming the result of the eradication and the histological changes. A gastric biopsy specimen for histological examination and Campylobacter-like organism testing was obtained from the lesser and greater curvature of the corpus of the remnant stomach. Histological changes in the gastric mucosa were assessed using the updated Sydney system before eradication therapy and at follow-up after 12 mo.RESULTS: Eradication rates with the first-line and second-line therapies were 78.4%(458/584) and 90%(36/40), respectively, by intention-to-treat analysis and 85.3%(458/530) and 92.3%(36/39), respectively, by per-protocol analysis. The univariate and multivariate analyses revealed that Billroth Ⅱ surgery was an independent factor predictive of eradication success in the eradication success group(OR = 1.53, 95%CI: 1.41-1.65, P = 0.021). The atrophy and intestinal metaplasia(IM) scores 12 mo after eradication were significantly lower in the eradication success group than in the eradication failure group(0.25 ± 0.04 vs 0.47 ± 0.12, P = 0.023; 0.27 ± 0.04 vs 0.51 ± 0.12, P = 0.015, respectively). The atrophy and IM scores 12 mo after successful eradication were significantly lower in the Billroth Ⅱ group than in the Billroth I group(0.13 ± 0.09 vs 0.31 ± 0.12, P = 0.029; 0.32 ± 0.24 vs 0.37 ± 0.13, P = 0.034, respectively).CONCLUSION: Patients with H. pylori following subtotal gastrectomy had a similar eradication rate to patients with an intact stomach. H. pylori eradication is recommended after subtotal gastrectomy. | Jae Jin Hwang Dong Ho Lee Kyu Keun Kang Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim | 2015 | World Journal of Gastroenterology2015，21，13： | 5 |
| 16 | Are human dental papilla-derived stem cell and human brain-derived neural stem cell transplantations suitable for treatment of Parkinson’s disease?显示文摘Transplantation of neural stem cells has been reported as a possible approach for replacing impaired dopaminergic neurons. In this study, we tested the efficacy of early-stage human dental papilla-derived stem cells and human brain-derived neural stem cells in rat models of 6-hydroxydopamine-induced Parkinson's disease. Rats received a unilateral injection of 6-hydroxydopamine into right medial forebrain bundle, followed 3 weeks later by injections of PBS, early-stage human dental papilla-derived stem cells, or human brain-derived neural stem cells into the ipsilateral striatum. All of the rats in the human dental papilla-derived stem cell group died from tumor formation at around 2 weeks following cell transplantation. Postmortem examinations revealed homogeneous malignant tumors in the striatum of the human dental papilla-derived stem cell group. Stepping tests revealed that human brain-derived neural stem cell transplantation did not improve motor dysfunction. In apomorphine-induced rotation tests, neither the human brain-derived neural stem cell group nor the control groups (PBS injection) demonstrated significant changes. Glucose metabolism in the lesioned side of striatum was reduced by human brain-derived neural stem cell transplantation. [18 F]-FP-CIT PET scans in the striatum did not demonstrate a significant increase in the human brain-derived neural stem cell group. Tyrosine hydroxylase (dopaminergic neuronal marker) staining and G protein-activated inward rectifier potassium channel 2 (A9 dopaminergic neuronal marker) were positive in the lesioned side of striatum in the human brain-derived neural stem cell group. The use of early-stage human dental papilla-derived stem cells confirmed its tendency to form tumors. Human brain-derived neural stem cells could be partially differentiated into dopaminergic neurons, but they did not secrete dopamine. | Hyung Ho Yoon Joongkee Min Nari Shin Yong Hwan Kim Jin-Mo Kim Yu-Shik Hwang Jun-Kyo Francis Suh Onyou Hwang Sang Ryong Jeon | 2013 | Neural Regeneration Research2013，8，13： | 5 |
| 17 | Deep-learning-based inverse design model for intelligent discovery of organic molecules显示文摘The discovery of high-performance functional materials is crucial for overcoming technical issues in modern industries.Extensive efforts have been devoted toward accelerating and facilitating this process,not only experimentally but also from the viewpoint of materials design.Recently,machine learning has attracted considerable attention,as it can provide rational guidelines for efficient material exploration without time-consuming iterations or prior human knowledge.In this regard,here we develop an inverse design model based on a deep encoder-decoder architecture for targeted molecular design.Inspired by neural machine language translation,the deep neural network encoder extracts hidden features between molecular structures and their material properties,while the recurrent neural network decoder reconstructs the extracted features into new molecular structures having the target properties.In material design tasks,the proposed fully data-driven methodology successfully learned design rules from the given databases and generated promising light-absorbing molecules and host materials for a phosphorescent organic light-emitting diode by creating new ligands and combinatorial rules. | Kyungdoc Kim Seokho Kang Jiho Yoo Youngchun Kwon Youngmin Nam Dongseon Lee Inkoo Kim Youn-Suk Choi Yongsik Jung Sangmo Kim Won-Joon Son Jhunmo Son Hyo Sug Lee Sunghan Kim Jaikwang Shin Sungwoo Hwang | 2018 | npj Computational Materials2018，，1： | 4 |
| 18 | Surgical palliation of unresectable pancreatic head cancer in elderly patients显示文摘AIM: To determine if surgical biliary bypass would provide improved quality of residual life and safe palliation in elderly patients with unresectable pancreatic head cancer. METHODS: Nineteen patients, 65 years of age or older, were managed with surgical biliary bypass (Group A). These patients were compared with 19 patients under 65 years of age who were managed with surgical biliary bypass (Group B). In addition, the results for group A were compared with those obtained from 17 patients, 65 years of age or older (Group C), who received percutaneous transhepatic biliary drainage to evaluate the quality of residual life. RESULTS: Five patients (26.0%) in Group A had complications, including one intraabdominal abscess, one pulmonary atelectasis, and three wound infections. One death (5.3%) occurred on postoperative day 3. With respect to morbidity, mortality, and postoperative hospitalization, no statistically significant difference was noted between Groups A and B. The number of readmissions and the rate of recurrent jaundice were lower in Group A than in Group C, to a statistically significant degree (P = 0.019, P = 0.029, respectively). The median hospital-free survival period and themedian overall survival were also signifi cantly longer in Group A (P = 0.001 and P < 0.001, respectively). CONCLUSION: Surgical palliation does not increase the morbidity or mortality rates, but it does increase the survival rate and improve the quality of life in elderly patients with unresectable pancreatic head cancer. | Sang Il Hwang Hyung Ook Kim Byung Ho Son Chang Hak Yoo Hungdai Kim Jun Ho Shin | 2009 | World Journal of Gastroenterology2009，15，8： | 4 |
