1Does the bile duct angulation affect recurrence of choledocholithiasis?显示文摘AIM:To investigate whether bile duct angulation and T-tube choledochostomy influence the recurrence of choledocholithiasis.METHODS:We conducted a retrospective study including 259 patients who underwent endoscopic sphincterotomy and cholecystectomy for choledocholithiasis between 2000 and 2007.The imaginary line was drawn along the center of the bile duct and each internal angle was measured at the two angulation sites ofthe bile duct respectively.The values of both angles were added together.We then tested our hypothesis by examining whether T-tube choledochostomy was performed and stone recurrence occurred by reviewing each subject's medical records.RESULTS:The overall recurrence rate was 9.3% (24 of 259 patients).The mean value of sums of angles in the recurrence group was 268.3°± 29.6°,while that in the non-recurrence group was 314.8°± 19.9° (P < 0.05).Recurrence rate of the T-tube group was 15.9% (17 of 107),while that of the non T-tube group was 4.6% (7 of 152) (P < 0.05).Mean value of sums of angles after T-tube drainage was 262.5°± 24.6° and that before T-tube drainage was 298.0°± 23.9° in 22 patients (P < 0.05).CONCLUSION:The bile duct angulation and T-tube choledochostomy may be risk factors of recurrence of bile duct stones.Dong Beom Seo Byoung Wook Bang Seok Jeong Don Haeng Lee Shin Goo Park Yong Sun Jeon Jung Il Lee Jin-Woo Lee 2011World Journal of Gastroenterology2011,17,36:15
2Scalable synthesis of nanoporous silicon microparticles for highly cyclable lithium-ion batteries显示文摘Nanoporous silicon is a promising anode material for high energy density batteries due to its high cycling stability and high tap density compared to other nanostructured anode materials.However,the high cost of synthesis and low yield of nanoporous silicon limit its practical application.Here,we develop a scalable,low-cost top-down process of controlled oxidation of Mg2Si in the air,followed by HCl removal of MgO to generate nanoporous silicon without the use of HF.By controlling the synthesis conditions,the oxygen content,grain size and yield of the porous silicon are simultaneously optimized from commercial standpoints.In situ environmental transmission electron microscopy reveals the reaction mechanism;the Mg2Si microparticle reacts with O2 to form MgO and Si,while preventing SiO2 formation.Owing to the low oxygen content and microscale secondary structure,the nanoporous silicon delivers a higher initial reversible capacity and initial Coulombic efficiency compared to commercial Si nanoparticles(3,033 mAh/g vs.2,418 mAh/g,84.3%vs.73.1%).Synthesis is highly scalable,and a yield of 90.4%is achieved for the porous Si nanostructure with the capability to make an excess of 10 g per batch.Our synthetic nanoporous silicon is promising for practical applications in next generation lithium-ion batteries.Jiangyan Wang William Huang Yong Seok Kim You Kyeong Jeong Sang Cheol Kim Jeffrey Heo Hiang Kwee Lee Bofei Liu Jaehou Nah Yi Cui 2020Nano Research2020,13,6:9
3Giant choledocholithiasis treated by mechanical lithotripsy using a gastric bezoar basket显示文摘Mechanical lithotripsy(ML) is usually considered as a standard treatment option for large bile duct stones.However,it is impossible to retrieve oversized stones because the conventional lithotripsy basket may not be able to grasp the stone.However,there is no established endoscopic extraction method for such giant stone removal.We describe a case of successful extraction of a 4-cm large stone using a gastric bezoar basket.A 78-year-old woman had suffered from upper abdominal pain for 20 d.Contrast-enhanced computed tomogram revealed a 4-cm single stone in the distal common bile duct(CBD).Endoscopic stone retraction was decided upon and endoscopic papillary balloon dilation was performed using a large balloon.An attempt to capture the stone using a standard lithotripsy basket failed due to the large stone size.Subsequently,we used a gastric bezoar basket to successfully capturethe stone.The stone was fragmented into small pieces and extracted.The stone was completely removed after two sessions of endoscopic retrograde cholangiopancreatography;each of which took 30 min.No complications occurred during or after the procedure.The patient was fully recovered and discharged on day 11 of hospitalization.ML using a gastric bezoar basket is a safe and effective retrieval method in select cases,and is considered as an alternative nonoperative option for the management of difficult CBD stones.Hyun Jung Chung Seok Jeong Don Haeng Lee Jung Il Lee Jin-Woo Lee Byoung Wook Bang Kye Sook Kwon Hyung Kil Kim Yong Woon Shin Young Soo Kim 2012World Journal of Gastroenterology2012,18,25:7
4Differential diagnosis of left-sided abdominal pain:Primary epiploic appendagitis vs colonic diverticulitis显示文摘AIM:To investigate the clinical characteristics of left primary epiploic appendagitis and to compare them with those of left colonic diverticulitis.METHODS:We retrospectively reviewed the clinical records and radiologic images of the patients who presented with left-sided acute abdominal pain and had computer tomography(CT) performed at the time of presentation showing radiological signs of left primary epiploic appendagitis(PEA) or left acute colonic diverticulitis(ACD) between January 2001 and December 2011. A total of 53 consecutive patients were enrolled and evaluated. We also compared the clinical characteristics,laboratory findings,treatments,and clinical results of left PEA with those of left ACD.RESULTS:Twenty-eight patients and twenty-five patients were diagnosed with symptomatic left PEA and ACD,respectively. The patients with left PEA had focal abdominal tenderness on the left lower quadrant(82.1%). On CT examination,most(89.3%) of the patients with left PEA were found to have an oval fatty mass with a hyperattenuated ring sign. In cases of left ACD,the patients presented with a more diffuse abdominal tenderness throughout the left side(52.0%vs 14.3%; P = 0.003). The patients with left ACD had fever and rebound tenderness more often than those with left PEA(40.0% vs 7.1%,P = 0.004; 52.0% vs14.3%,P = 0.003,respectively). Laboratory abnormalities such as leukocytosis were also more frequently observed in left ACD(52.0% vs 15.4%,P = 0.006).CONCLUSION:If patients have left-sided localized abdominal pain without associated symptoms or laboratory abnormalities,clinicians should suspect the diagnosis of PEA and consider a CT scan.Jeong Ah Hwang Sun Moon Kim Hyun Jung Song Yu Mi Lee Kyung Min Moon Chang Gi Moon Hoon Sup Koo Kyung Ho Song Yong Seok Kim Tae Hee Lee Kyu Chan Huh Young Woo Choi Young Woo Kang Woo Suk Chung 2013World Journal of Gastroenterology2013,19,40:6
5Anxiety and depression propensities in patients with acute toxic liver injury显示文摘AIM:To investigate anxiety and depression propensities in patients with toxic liver injury.METHODS:The subjects were divided into three groups:a healthy control group(Group 1,n=125),an acute non-toxic liver injury group(Group 2,n=124),and a group with acute toxic liver injury group caused by noncommercial herbal preparations(Group 3,n=126).These three groups were compared and evaluated through questionnaire surveys and using the Hospital Anxiety-Depression Scale(HADS),Beck Anxiety Inventory(BAI),Beck Depression Inventory(BDI),and the hypochondriasis scale.RESULTS:The HADS anxiety subscale was 4.9±2.7,5.0±3.0 and 5.6±3.4,in Groups 1,2,and 3,respectively.The HADS depression subscale in Group 3 showed the most significant score(5.2±3.2,6.4±3.4 and 7.2±3.4in Groups 1,2,and 3,respectively)(P<0.01 vs Group 1,P<0.05 vs Group 2).The BAI and BDI in Group 3showed the most significant score(7.0±6.3 and 6.9±6.9,9.5±8.6 and 8.8±7.3,10.7±7.2 and 11.6±8.5in Groups 1,2,and 3,respectively)(BAI:P<0.01 vs Group 1,P<0.05 vs Group 2)(BDI:P<0.01 vs Group1 and 2).Group 3 showed a significantly higher hypochondriasis score(8.2±6.0,11.6±7.5 and 13.1±6.5in Groups 1,2,and 3,respectively)(P<0.01 vs Group 1,P<0.05 vs Group 2).CONCLUSION:Psychological factors that present vulnerability to the temptation to use alternative medicines,such as herbs and plant preparations,are important for understanding toxic liver injury.Jeong Ill Suh Jeong Kyu Sakong Kwan Lee Yong Kook Lee Jeong Bae Park Dong Joon Kim Yeon Seok SeoDepartment of Internal Medicine Korea University Anam Hospital Korea University College of Medicine Seoul 136-705 South Korea Jae Dong Lee Soon Young Ko Byung Seok Lee Seok Hyun Kim Byung Seok Kim Young Seok Kim Heon Ju Lee In Hee Kim Joo Hyun Sohn Tae Yeob Kim Byung Min Ahn 2013World Journal of Gastroenterology2013,19,47:5
6Is there correlation between pancreatic enzyme and radiological severity in acute pancreatitis?显示文摘AIM: To investigate the correlation between the changes of pancreatic enzyme, the biochemical markers and the clinical results according to the Balthazar computer tomography (CT) grade. METHODS: Between July 2004 and July 2005, we reviewed the charts of 119 patients who were admitted to our hospital with acute pancreatitis. RESULTS: Eighty-three patients (69.7%) were male, and the mean age of the patients was 57 ± 15.7 years. The biliary pancreatitis patients had an older mean age. Forty-nine patients (41.1%) had biliary pancreatitis and forty-six (38.6%) had alcoholic pancreatitis. Group 3 patients had a longer duration of pain (2.51 ± 1.16 vs 3.17 ± 1.30 vs 6.56 ± 6.13, P < 0.001), a longer period of fasting (7.49 ± 4.65 vs 10.65 ± 5.54 vs 21.88 ± 13.81, P < 0.001) and a longer hospital stay (9.17 ± 5.34 vs 14.63 ± 8.65 vs 24.47 ± 15.52, P < 0.001) than the other groups. On the univariate analysis, the factors that affected the radiological grade were the leukocyte count at admission (P = 0.048), the hemoglobin (P = 0.016) and total bilirubin concentrations (P = 0.023), serum lipase (P = 0.009), the APACH Ⅱ scores at admission (P = 0.017), the APACH Ⅱ scores after 24 h (P = 0.031), the C-reactive protein (CRP) titer (P = 0.0001) and the follow up CRP titer (P = 0.003). But the CRP level (P = 0.001) and follow up CRP titer (P = 0.004) were only correlated with the radiological grade on multivariate analysis. According to the ROC curve, when we set the CRP cut off value at 83 mg/L, the likelihoodratio for a positive test was 3.84 and the likelihood ratio for a negative test was 0.26 in group 3. CONCLUSION: In conclusion, our study suggests that the CRP with the radiological severity may be used to estimate the severity of acute pancreatitis.Yeon Soo Kim Byung Seok Lee Seok Hyun Kim Jae Kyu Seong Hyun Yong Jeong Heon Young Lee 2008World Journal of Gastroenterology2008,14,15:5

8Expression of Ki-67,p53,and K-ras in chronic pancreatitis and pancreatic ductal adenocarcinoma显示文摘AIM: To examine surgical specimens of pancreas with either chronic pancreatitis or pancreatic cancer in order to study whether ductal hyperplasia and dysplasia in pancreas represent precursor lesions for pancreatic cancer.METHODS: We examined expression of Ki-67, CEA,p53, and K-ras, in the surgical specimens of pancreas with adenocarcinomas (n = 11) and chronic pancreatitis (n = 12). Cellular proliferation was assessed by Ki-67proliferation index using the proliferation marker Ki-67.In specimens with pancreas cancer, we divided pancreas epithelium into normal (n=7), ductal hyperplasia (n=3), dysplasia (n=4), and cancerous lesion (n=11) after hematoxylin and eosin staining, Ki-67, and CEA immunohistochemical staining. In cases with chronic pancreatitis, the specimen was pathologically examined as in cases with pancreas cancer, and they were also determined as normal (n=10), ductal hyperplasia (n=4), or dysplasia (n= 5). p53 and K-ras expression were also studied by immunohistochemical staining.RESULTS: In pancreatic cancer, the Ki-67 index was 3.73±3.58 in normal site, 6.62±4.39 in ductalhyperplasia, 13.47±4.02 in dysplasia and 37.03±10.05in cancer tissue, respectively. Overall, p53 was positive in normal ducts, ductal hyperplasia, dysplasia, and carcinoma cells in 0 of 14 (0%), 0 of 7 (0%), 7 of 9 (78%),and 10 of 11 (91%), respectively, and K-ras was positive in 0 of 8 (0%), 1 of 3 (33%), 4 of 6 (67%), 4 of 5 (80%),respectively.CONCLUSION: Our results favorably support the hypothesis that ductal hyperplasia and dysplasia of the pancreas might be precursor lesions for pancreas cancer.Further evaluation of oncogenes by the molecular study is needed.Seok Jeong Don Haeng Lee Jung Il Lee Jin-Woo Lee Kye Sook Kwon Pum-Soo Kim Hyung Gil Kim Yong Woon Shin Young Soo Kim Young Bae Kim 2005World Journal of Gastroenterology2005,11,43:4
9Risk factors for metachronous gastric carcinoma development after endoscopic resection of gastric dysplasia: Retrospective, single-center study显示文摘AIM To determine the gastric adenocarcinoma(GAC)occurrence rate and related factors,we evaluated the follow-up results of patients confirmed to have gastric dysplasia after endoscopic resection(ER).METHODS We retrospectively analyzed the medical records,endoscopic examination records,endoscopic procedure records,and histological records of 667 cases from641 patients who were followed-up for at least 12mo,from among 1273 patients who were conformed to have gastric dysplasia after Endoscopic mucosal resection(EMR)or endoscopic submucosal dissection (ESD)of gastric mucosal lesions between January 2007and August 2013 at the Chungnam National University Hospital.RESULTS The mean follow-up period was 33.8 mo,and the median follow-up period was 29 mo(range:12-87).During the follow-up period,the occurrence of metachronous GAC was 4.0%(27/667).The mean and median interval periods between the occurrence of metachronous GAC and endoscopic treatment of gastric dysplasia were 36.3 and 34 mo,respectively(range:16-71).The factors related to metachronous GAC occurrence after ER for gastric dysplasia were male sex(5.3%vs 1.0%),open-type atrophic gastritis(9.5%vs3.4%),intestinal metaplasia(6.8%vs 2.4%),and highgrade dysplasia(HGD;8.4%vs 3.2%).Among them,male sex[OR:5.05(1.18-21.68),P=0.029],intestinal metaplasia[OR:2.78(1.24-6.23),P=0.013],and HGD[OR:2.70(1.16-6.26),P=0.021]were independent related factors in multivariate analysis.Furthermore,24of 27 GAC cases(88.9%)occurred at sites other than the previous resection sites,and 3(11.1%)occurred at the same site as the previous resection site.CONCLUSION Male sex,intestinal metaplasia,and HGD were significantly related to the occurrence of metachronous GAC after ER of gastric dysplasia,and most GACs occurred at sites other than the previous resection sites.Hee Seok Moon Gee Young Yun Ju Seok Kim Hyuk Soo Eun Sun Hyung Kang Jae Kyu Sung Hyun Yong Jeong Kyu-Sang Song 2017World Journal of Gastroenterology2017,23,24:3
10Spectrum of final pathological diagnosis of gastric adenoma after endoscopic resection显示文摘AIM: To investigate how many discrepancies occur in patients before and after endoscopic treatment of referred adenoma and the reason for these results. METHODS: We retrospectively reviewed data from 554 cases of 534 patients who were referred from primary care centres for adenoma treatment and treated for endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) at Chungnam National University Hospital, from July 2006 to June 2009. Reendoscopy was examined in 142 cases and biopsywas performed in 108 cases prior to treatment. Three endoscopists (1, 2 and 3) performed all EMRs or ESDs and three pathologists (1, 2 and 3) diagnosed most of the cases. Transfer notes, medical records and endoscopic pictures of these cases were retrospectively reviewed and analyzed. RESULTS: Adenocarcinoma was 72 (13.0%) cases in total 554 cases after endoscopic treatment of referred adenoma. When the grade of dysplasia was high (55.0%), biopsy number was more than three (22.7%), size was no smaller than 2.0 cm (23.2%), morphologic type was depressed (35.8%) or yamada type Ⅳ (100%), and color was red (30.9%) or mixed-or-undetermined (25.0%), it had much more malignancy rate than the others (P < 0.05). All 18 cases diagnosed as adenocarcinoma in the re-endoscopic forceps biopsy were performed by endoscopist 1. There were different malignancy rates according to the pathologist (P = 0.027). CONCLUSION: High grade dysplasia is the most important factor for predicting malignancy as a final pathologic diagnosis before treating the referred gastric adenoma. This discrepancy can occur mainly through inappropriately selecting a biopsy site where cancer cells do not exist, but it also depends on the pathologist to some extent.Kwan Woo Nam Kyu Sang Song Heon Young Lee Byung Seok Lee Jae Kyu Seong Seok Hyun Kim Hee Seok Moon Eaum Seok Lee Hyun Yong Jeong 2011World Journal of Gastroenterology2011,17,47:2

13Elucidating Ion Transport Phenomena in Sulfide/Polymer Composite Electrolytes for Practical Solid-State Batteries显示文摘Despite the enormous interest in inorganic/polymer composite solid-state electrolytes(CSEs)for solid-state batteries(SSBs),the underlying ion transport phenomena in CSEs have not yet been elucidated.Here,we address this issue by formulating a mechanistic understanding of bi-percolating ion channels formation and ion conduction across inorganic-polymer electrolyte interfaces in CSEs.A model CSE is composed of argyrodite-type Li_6PS_5Cl(LPSCl)and gel polymer electrolyte(GPE,including Li~+-glyme complex as an ion-conducting medium).The percolation threshold of the LPSCl phase in the CSE strongly depends on the elasticity of the GPE phase.Additionally,manipulating the solvation/desolvation behavior of the Li~+-glyme complex in the GPE facilitates ion conduction across the LPSCl-GPE interface.The resulting scalable CSE(area=8×6(cm×cm),thickness~40μm)can be assembled with a high-mass-loading LiNi_(0.7)Co_(0.15)Mn_(0.15)O_(2)cathode(areal-mass-loading=39 mg cm~(-2))and a graphite anode(negative(N)/positive(P)capacity ratio=1.1)in order to fabricate an SSB full cell with bi-cell configuration.Under this constrained cell condition,the SSB full cell exhibits high volumetric energy density(480 Wh L_(cell)~(-1))and stable cyclability at 25℃,far exceeding the values reported by previous CSE-based SSBs.Kyeong‑Seok Oh Ji Eun Lee Yong‑Hyeok Lee Yi‑Su Jeong Imanuel Kristanto Hong‑Seok Min Sang‑Mo Kim Young Jun Hong Sang Kyu Kwak Sang‑Young Lee 2023Nano-Micro Letters2023,15,10:2
14Phase Ⅱ study of R-CVP followed by rituximab maintenance therapy for patients with advanced marginal zone lymphoma:consortium for improving survival of lymphoma(CISL)study显示文摘Background:The response rate and survival improvement for rituximab,a CD20-targeting monoclonal antibody,have been demonstrated in marginal zone lymphoma(MZL)as monotherapy and in combination with chemotherapeutic regimens,yet relapses still occur despite treatment completion.Thus,extending the period of remission in MZL patients remains an essential goal.This multicenter,single-arm,open-label phase II study evaluated the survival efficacy of 2 years of rituximab-maintenance therapy in patients with stage III-IV CD20-positive MZL who had responded to first-line R-CVP(rituximab,cyclophosphamide,vincristine,and prednisolone).The objective of this study was to determine whether rituximab maintenance following R-CVP warrants further investigation.Methods:Prior to rituximab-maintenance therapy,patients received 6-8 cycles of first-line R-CVP therapy for stage III-IV MZL.Rituximab(375 mg/m^(2)),cyclophosphamide(750 mg/m^(2)),and vincristine(1.4 mg/m^(2);maximum 2 mg)were administered via an intravenous infusion on day 1 of each 3-week cycle,while oral prednisolone(100 mg)was given on days 1-5 of each 3-week cycle.The patients who achieved complete response(CR),partial response(PR),or stable disease(SD)to R-CVP treatment,were prescribed rituximab-maintenance therapy which was administered intravenously at a dose of 375 mg/m^(2) every 8 weeks for up to 12 cycles.The primary endpoint was progression-free survival(PFS).Secondary endpoints were overall survival(OS)and treatment safety.Results:47 patients were enrolled,of whom,45(96%)received rituximab-maintenance treatment.Fifteen(33%)patients had nodal MZL.Following R-CVP first-line therapy,20(44%),22(49%),and 3(7%)patients achieved CR,PR,and SD,respectively.After a median follow-up of 38.2 months,their observed 3-year PFS rate was 81%.During the rituximab-maintenance,6 PR and 1 SD patients achieved CR following the administration of R-CVP.Elevated LDH and the presence of B symptoms were found to be significant prognostic factors for PFS(P=0.003)and demonstrated a 3-year OS rate of 90%.Rituximab-maintenance therapy was well tolerated,and the common treatment-emergent adverse events were sensory neuropathy(18%),myalgia(13%),fatigue(9%),and neutropenia(9%).Conclusion: Rituximab-maintenance therapy following first-line R-CVP demonstrated good PFS in patients with stage III-IV MZL, in addition to a favorable toxicity profile.Sung Yong Oh Won Seog Kim Jin Seok Kim Seok Jin Kim Dok Hyun Yoon Deok-Hwan Yang Won Sik Lee Hyo Jung Kim Ho-Young Yhim Seong Hyun Jeong Jong Ho Won Suee Lee Jee Hyun Kong Sung-Nam Lim Jun Ho Ji Kyung A.Kwon Gyeong-Won Lee Jae Hoon Lee Ho Sup Lee Ho-Jin Shin Cheolwon Suh 2019Cancer Communications2019,39,1:2
