2Comparative study of chitosan/fibroin–hydroxyapatite and collagen membranes for guided bone regeneration in rat calvarial defects: micro-computed tomography analysis显示文摘This study aimed to utilize micro-computed tomography(micro-CT)analysis to compare new bone formation in rat calvarial defects using chitosan/fibroin–hydroxyapatite(CFB–HAP)or collagen(Bio-Gide)membranes.Fifty-four(54)rats were studied.A circular bony defect(8 mm diameter)was formed in the centre of the calvaria using a trephine bur.The CFB–HAP membrane was prepared by thermally induced phase separation.In the experimental group(n518),the CFB–HAP membrane was used to cover the bony defect,and in the control group(n518),a resorbable collagen membrane(Bio-Gide)was used.In the negative control group(n518),no membrane was used.In each group,six animals were euthanized at 2,4 and 8 weeks after surgery.The specimens were then analysed using micro-CT.There were significant differences in bone volume(BV)and bone mineral density(BMD)(P,0.05)between the negative control group and the membrane groups.However,there were no significant differences between the CFB–HAP group and the collagen group.We concluded that the CFB–HAP membrane has significant potential as a guided bone regeneration(GBR)membrane.Jae Min Song Sang Hun Shin Yong Deok Kim Jae Yeol Lee Young Jae Baek Sang Yong Yoon Hong Sung Kim 2014International Journal of Oral Science2014,6,2:15
3Diagnostic value of maximal-outer-diameter and maximal-mural-thickness in use of ultrasound for acute appendicitis in children显示文摘AIM: To evaluate the maximal-outer-diameter (MOD) and the maximal-mural-thickness (MMT) of the appendix in children with acute appendicitis and to determine their optimal cut-off values to diagnose acute appendicitis. METHODS: In total, 164 appendixes from 160 children between 1 and 17 years old (84 males, 76 females; mean age, 7.38 years) were examined by high-resolution abdominal ultrasound for acute abdominal pain and the suspicion of acute appendicitis. We measured the MOD and the MMT at the thickest point of the appendix. Patients were categorized into two groups according to their medical records: patients who had surgery (surgical appendix group) and patients who did not have surgery (non-surgical appendix group). Data were analyzed by MedCalc v.9.3. The rank sum test (Mann-Whitney test) was used to evaluate the difference in the MOD and the MMT between the two groups. ROC curve analysis was used to determine the optimal cut-off value of the MOD and the MMT on diagnosis of acute appendicitis. RESULTS: There were 121 appendixes (73.8%) in the non-surgical appendix group and 43 appendixes (26.2%) in the surgical appendix group. The median MOD differed significantly between the two groups (0.37 cm vs 0.76 cm, P < 0.0001), and the median MMT also differed (0.15 cm vs 0.33 cm, P < 0.0001). The optimal cut-off value of the MOD and the MMT for diagnosis of acute appendicitis in children was > 0.57 cm (sensitivity 95.4%, specificity 93.4%) and > 0.22 cm (sensitivity 90.7%, specificity 79.3%), respectively. CONCLUSION: The MOD and the MMT are reliable criteria to diagnose acute appendicitis in children. An MOD > 0.57 cm and an MMT > 0.22 cm are the optimal criteria.Bo-Kyung Je Sung-Bum Kim Seung Hwa Lee Ki Yeol Lee Sang Hoon Cha 2009World Journal of Gastroenterology2009,15,23:14

5Absolute monocyte and lymphocyte count prognostic score for patients with gastric cancer显示文摘AIM:To measure the prognostic significance of absolute monocyte count/absolute lymphocyte count prognostic score(AMLPS) in patients with gastric cancer.METHODS:We retrospectively examined the combination of absolute monocyte count(AMC) and absolute lymphocyte count(ALC) as prognostic variables in a cohort of 299 gastric cancer patients who underwent surgical resection between 2006 and 2013 and were followed at a single institution.Both AMC and ALC were dichotomized into two groups using cut-off points determined by receiving operator characteristic curve analysis.An AMLPS was generated,which stratified patients into three risk groups:low risk(both low AMC and high ALC),intermediate risk(either high AMC or low ALC),and high risk(both high AMC and low ALC).The primary objective of the study was to validate the impact of AMLPS on both disease-free survival(DFS) and overall survival(OS),and the second objective was to assess the AMLPS as an independent prognostic factor for survival in comparison with known prognostic factors.RESULTS:Using data from the entire cohort,the most discriminative cut-off values of AMC and ALC selected on the receiver operating characteristic curve were 672.4/μL and 1734/μL for DFS and OS.AMLPS risk groups included 158(52.8%) patients in the lowrisk,128(42.8%) in the intermediate-risk,and 13(4.3%) in the high-risk group.With a median followup of 37.2 mo(range:1.7-91.4 mo),five-year DFS rates in the low-,intermediate-,and high-risk groups were 83.4%,78.7%,and 19.8%,respectively.And fiveyear OS rates in the low-,intermediate-,and high-risk groups were 89.3%,81.1%,and 14.4%,respectively.On multivariate analysis performed with patient- and tumor-related factors,we identified AMLPS,age,and pathologic tumor-node-metastasis stage as the most valuable prognostic factors impacting DFS and OS.CONCLUSION:AMLPS identified patients with a poor DFS and OS,and it was independent of age,pathologic stage,and various inflammatory markers.Wan Kyu Eo Da Wun Jeong Hye Jung Chang Kyu Yeoun Won Sung Il Choi Se Hyun Kim Sung Wook Chun Young Lim Oh Tae Hwa Lee Young Ok Kim Ki Hyung Kim Yong Il Ji Ari Kim Heung Yeol Kim 2015World Journal of Gastroenterology2015,21,9:6
6Comparison of two Nd:YAG laser posterior capsulotomy: cruciate pattern vs circular pattern with vitreous strand cutting显示文摘AIM: To investigate the effects and safety of neodymium: yttrium-aluminium-garnet(Nd:YAG) laser posterior capsulotomy with vitreous strand cuttingMETHODS: A total of 40 eyes of 37 patients with symptomatic posterior capsular opacity(PCO) were included in this prospective randomized study and were randomly subjected to either cruciate pattern or round pattern Nd:YAG posterior capsulotomy with vitreous strand cutting(modified round pattern). The best corrected visual acuity(BCVA), intraocular pressure(IOP), refractive error, endothelial cell count(ECC), anterior segment parameters, including anterior chamber depth(ACD) and anterior chamber angle(ACA) were measured before and 1 mo after the laser posterior capsulotomy. RESULTS: In both groups, the BCVA improved significantly(P<0.001 for the modified round pattern group, P=0.001 for the cruciate pattern group); the IOP and ECC did not significantly change. The ACD significantly decreased(P<0.001 for both) and the ACA significantly increased(P=0.001 for the modified round pattern group and P=0.034 for the cruciate group). The extent of changes in these parameters was not significantly different between the groups.CONCLUSION: Modified round pattern Nd:YAG laser posterior capsulotomy is an effective and safe method for the treatment of PCO. This method significantly changes the ACD and ACA, but the change in refraction is not significant. Modified round pattern Nd:YAG laser posterior capsulotomy can be considered a good alternative procedure in patients with symptomatic PCO.Jin-Soo Kim Jung Yeol Choi Ji-Won Kwon Won Ryang Wee Young Keun Han 2018International Journal of Ophthalmology(English edition)2018,11,2:6

8Rheostatic Control of ABA Signaling through HOS15-Mediated OST1 Degradation显示文摘Dehydrating stresses trigger the accumulation of abscisic acid(ABA),a key plant stress-signaling hormone that activates Snf1-Related Kinases(SnRK2s)to mount adaptive responses.However,the regulatory circuits that terminate the SnRK2s signal relay after acclimation or post-stress conditions remain to be defined.Here,we show that the desensitization of the ABA signal is achieved by the regulation of OST1(SnRK2.6)protein stability via the E3-ubiquitin ligase HOS15.Upon ABA signal,HOS15-induced degradation of OST1 is inhibited and stabilized OST1 promotes the stress response.When the ABA signal terminates,protein phosphatases ABI1/2 promote rapid degradation of OST1 via HOS15.Notably,we found that even in the presence of ABA,OST1 levels are also depleted within hours of ABA signal onset.The unexpected dynamics of OST1 abundance are then resolved by systematic mathematical modeling,demonstrating a desensitizing feedback loop by which OST1-induced upregulation of ABI1/2 leads to the degradation of OST1.This model illustrates the complex rheostat dynamics underlying the ABA-induced stress response and desensitization.Akhtar Ali Jae Kyoung Kim Masood Jan Haris Ali Khan Irfan Ullah Khan Mingzhe Shen Junghoon Park Chae Jin Lim Shah Hussain Dongwon Baek Kai Wang Woo Sik Chung Vicente Rubio Sang Yeol Lee Zhizhong Gong Woe Yeon Kim Ray ABressan Jose MPardo Dae-Jin Yun 2019Molecular Plant2019,12,11:5
9Carcinoma of the middle bile duct:Is bile duct segmental resection appropriate?显示文摘AIM:To compare survival between bile duct segmental resection(BDSR)and pancreaticoduodenectomy(PD) for treating distal bile duct cancers. METHODS:Retrospective analysis was conducted for 45 patients in a BDSR group and for 149 patients in a PD group. RESULTS:The T-stage(P<0.001),lymph node invasion (P=0.010)and tumor differentiation(P=0.005)were significant prognostic factors in the BDSR group.The 3-and 5-year overall survival rates for the BDSR group and PD group were 51.7%and 36.6%,respectively and 46.0%and 38.1%,respectively(P=0.099).The BDSR group and PD group did not show any significant difference in survival when this was adjusted for the TNM stage.The 3-and 5-year survival rates were: stageⅠa[BDSR(100.0%and 100.0%)vs PD(76.9% and 68.4%)(P=0.226)];stageⅠb[BDSR(55.8% and 32.6%)vs PD(59.3%and 59.3%)(P=0.942)]; stageⅡb[BDSR(19.2%and 19.2%)vs PD(31.9%and 14.2%)(P=0.669)]. CONCLUSION:BDSR can be justified as an alternative radical operation for patients with middle bile duct inselected patients with no adjacent organ invasion and resection margin is negative.Hyung Geun Lee Sang Hoon Lee Dong Do Yoo Kwang Yeol Paik Jin Seok Heo Seong Ho Choi Dong Wook Choi 2009World Journal of Gastroenterology2009,15,47:3
10Effectiveness of gastric cancer screening programs in South Korea:Organized vs opportunistic models显示文摘AIM:To investigate the outcome and effectiveness of two screening programs,National Cancer Screening Program(NCSP)and opportunistic screening(OS),for the detection of gastric cancer. METHODS:A total of 45 654 subjects underwent upper endoscopy as part of the NCSP or OS at the Chung-Ang University Healthcare System in Korea between January 2007 and December 2010.The study population was comprised of subjects over the age of 40 years.More specifically,subjects who took part in the NCSP were Medicaid recipients and beneficiaries of the National Health Insurance Corporation.Still photo-graphs from the endoscopies diagnosed as gastric cancer were reviewed by two experienced endoscopists. RESULTS:The mean age of the screened subjects was 55 years for men and 54 years for women.A total of 126 cases(0.28%)of gastric cancer were detected from both screening programs;100 cases(0.3%)from NCSP and in 26 cases(0.2%)from OS.The proportion of early gastric cancer(EGC)detected in NCSP was higher than that in OS(74.0%vs 53.8%,P=0.046). Among the 34 416 screenees in NCSP,6585(19.1%) underwent upper endoscopy every other year as scheduled.Among the 11 238 screenees in OS,3050(27.1%) underwent upper endoscopy at least once every two years during the study period.The detection rate of gastric cancer was found to be significantly higher during irregular follow-up than during regular follow-up in both screening programs(0.3%vs 0.2%,P=0.036).A higher incidence of EGC than advanced gastric cancer was observed during regular follow-up compared with irregular follow-up. CONCLUSION:Compliance to the screening program is more important than the type of screening system used.Beom Jin Kim Chae Heo Byoung Kwon Kim Jae Yeol Kim Jae Gyu Kim 2013World Journal of Gastroenterology2013,19,5:3
11Experience of limited pancreatic head resection for management of branch duct intraductal papillary mucinous neoplasm in a single center显示文摘AIM: To share our surgical experience and the outcome of limited pancreatic head resection for the management of branch duct intraductal papillary mucinous neoplasm (IPMN). METHODS: Between May 2005 and February 2008, nine limited pancreatic head resections (LPHR) were performed for IPMN of the pancreatic head. We reviewed the nine patients, retrospectively. RESULTS: Tumor was located in the uncinate process of the pancreas in all nine patients. Three patients had stents inserted in the main pancreatic duct due to injury. The mean size of tumor was 28.4 mm. Postoperative complications were found in f ive patients: 3 pancreatic leakages, a pancreatitis, and a duodenal stricture. Pancreatic leakages were improved by external drainage. No perioperative mortality was observed and all patients are recorded alive during the mean follow-up period of 17.2 mo. CONCLUSION: In selected patients after careful evaluation, LPHR can be used for the treatment of branch duct type IPMN. In order to avoid pancreatic ductal injury, preand intra-operative defi nite localization and careful operative techniques are required.Kwang Yeol Paik Seong Ho Choi 2009World Journal of Gastroenterology2009,15,23:3
12Effects of upper lid blepharoplasty on visual quality in patients with lash ptosis and dermatochalasis显示文摘AIM:To assess the effects of upper lid blepharoplasty on visual quality.METHODS:Seventy-three eyelids of 39 patients were subjected to upper lid blepharoplasty.Pre- and postoperative contrast sensitivity,visual acuity,vertical palpebral aperture and the degree of lash ptosis were measured.RESULTS:The mean log contrast sensitivities under photopic(P =0.017) and scotopic conditions(P =0.009)were improved after surgery,and these differences were significant.The degree of lash ptosis was also decreased after blepharoplasty(P<0.001).CONCLUSION:In our study,a significant increase in contrast sensitivity was found after surgery.These results suggest that upper lid blepharoplasty can be helpful for improving visual quality.Scoung Hyun An Sang Wook Jin Yoon Hyung Kwon Won Yeol Ryu Woo Jin Jeong Hee Bae Ahn 2016International Journal of Ophthalmology(English edition)2016,9,9:3
13Ataxic gait following total gastrectomy for gastric cancer显示文摘A 58-year-old woman, who had undergone total gastrectomy for early gastric cancer 9 years previously, visited the outpatient clinic complaining of progressive difficulty in walking for 15 d. Laboratory examinations showed macrocytic anemia and a decreased serum vitamin B12 concentration and increased serum concentrations of folate, vitamin E and copper. Magnetic resonance imaging showed multifocal high signal intensities along the posterior column of the cervical and thoracic spinal cord. Treatment consisted of intramuscular injections of vitamin B12 for 7 d, which increased her serum level of vitamin B12 to normal. This was followed by weekly intramuscular injections of vitamin B12 for another 2 wk and oral administration of vitamin B12 three times per day. After comprehensive rehabilitation for 4 wk, she showed sufficient improvements in strength and ataxic gait, enabling her to return to her normal daily activities.Chang Ho Hwang Dong Jin Park Gyu Yeol Kim 2016World Journal of Gastroenterology2016,22,37:3

17Activation of immediate-early response gene c-Fos protein in the rat paralimbic cortices after myocardial infarction显示文摘c-Fos is a good biological marker for detecting the pathogenesis of central nervous system disorders. Few studies are reported on the change in myocardial infarction-induced c-Fos expression in the paralimbic regions. Thus, in this study, we investigated the changes in c-Fos expression in the rat cingulate and piriform cortices after myocardial infarction. Neuronal degeneration in cingulate and piriform cortices after myocardial infarction was detected using cresyl violet staining, Neu N immunohistochemistry and Fluoro-Jade B histofluorescence staining. c-Fos-immunoreactive cells were observed in cingulate and piriform cortices at 3 days after myocardial infarction and peaked at 7 and 14 days after myocardial infarction. But they were hardly observed at 56 days after myocardial infarction. The chronological change of c-Fos expression determined by western blot analysis was basically the same as that of c-Fos immunoreactivity. These results indicate that myocardial infarction can cause the chronological change of immediate-early response gene c-Fos protein expression, which might be associated with the neural activity induced by myocardial infarction.Ji Yun Ahn Hyun-Jin Tae Jeong-Hwi Cho In Hye Kim Ji Hyeon Ahn Joon Ha Park Dong Won Kim Jun Hwi Cho Moo-Ho Won Seongkweon Hong Jae-Chul Lee Jeong Yeol Seo 2015Neural Regeneration Research2015,10,8:2
18Analysis of liver metastasis after resection for pancreatic ductal adenocarcinoma显示文摘AIM:To investigate the risk factors affecting the liver metastasis(LM) of pancreatic ductal adenocarcinoma(PDAC) after resection.METHODS:We retrospectively analyzed 101 PDAC patients who underwent surgical resection at the Samsung Medical Center between January 2000 and December 2004.Forty one patients with LM were analyzed for the time of metastasis,prognostic factors affecting LM,and survival.RESULTS:LM was found in 40.6%.The median time of the LM(n = 41) was 6.0 ± 4.6 mo and most LM occurred within 1 year.In univariate analysis,tumor size,preoperative carbohydrate antigen 19-9,and perineural invasion were factors affecting LM after resection.In multivariate analysis,tumor size was the most important factor for LM.In univariate analysis,tumor cell differentiation was significant to LM in low-risk groups.CONCLUSION:LM after resection of PDAC occurs early and shows poor survival.Tumor size is the key indicator for LM after resection.Kwang Yeol Paik Seong Ho Choi Jin Seok Heo Dong Wook Choi 2012World Journal of Gastrointestinal Oncology2012,4,5:2
19Pathologic response to preoperative transarte- rial chemoembolization for resectable hepatocellular carcinoma may not predict recurrence after liver resection显示文摘BACKGROUND: Pathologic response(PR) predicts survival after preoperative chemotherapy and resection of a malignancy. Occasionally, transarterial chemoembolization(TACE)may be selected for preoperative management of resectable hepatocellular carcinoma(HCC). This study investigated whether PR to preoperative TACE can predict recurrence after resection for resectable HCC.METHODS: We conducted analysis of 106 HCC patients who underwent TACE followed by liver resection with a curative intent. The PR was evaluated as the mean percentage of nonviable tumor area within each tumor. We divided the patients into three groups according to response rate: complete PR(CPR), major response(MJR: PR≥50%) and minor response(MNR: PR<50%). The primary endpoint was disease-free survival, and the secondary endpoints were predicting factors for tumor recurrence and MJR+CPR.RESULTS: Among the 121 TACE patients, PR could be measured in 106(87.6%). The mean interval between TACE and liver resection was 33.1 days. The 5-year disease-free survival rates by PR status were as follows: 40.6% CPR, 43.7% MJR, and 49.0% MNR(P=0.815). There were also no significant differences in overall survival between the three groups. Multivariate analyses revealed that microvascular invasion and capsular invasion(hazard ratio [HR]=11.224, P=0.002 and HR=2.220P=0.043) were independent predictors of disease-free survival.Multivariate analysis of the predictors of above 50% PR revealed that only hepatitis B was an independent factor.CONCLUSION: These data could reflect that the PR after TACE for resectable HCC may not be useful for predicting recurrence of HCC after resection.Kwang Yeol Paik Eung Kook Kim 2016Hepatobiliary & Pancreatic Diseases International2016,15,2:2
