| 1 | Limited endoscopic sphincterotomy plus large balloon dilation for choledocholithiasis with periampullary diverticula显示文摘AIM: To investigate the effectiveness and safety of limited endoscopic sphincterotomy (EST) plus large balloon dilation (LBD) for removing choledocholithiasis in patients with periampullary diverticula (PAD). METHODS: A total of 139 patients with common bile duct (CBD) stones were treated with LBD (10-20 mm balloon diameter) after limited EST. Of this total, 73 patients had PAD and 66 patients did not have PAD (controls). The results of stone removal and complications were retrospectively evaluated. RESULTS: There were no significant differences between the PAD and the control groups in overall successful stone removal (94.5% vs 93.9%), stone removal in first session (69.9% vs 81.8%), mechanical lithotripsy (12.3% vs 13.6%), and complications (11.0% vs 7.6%). Clinical outcomes were also similar between the types of PAD, but the rate of stone removal in first session and the number of sessions were significantly lower and more frequent, respectively, in type B PAD (papilla located near the diverticulum) than controls [23/38 (60.5%) vs 54/66 (81.8%), P = 0.021; and 1 (1-2) vs 1 (1-3), P = 0.037, respectively] and the frequency of pancreatitis was significantly higher in type A PAD (papilla located inside or in the margin of the diverticulum) than in controls (16.1% vs 3.0%, P = 0.047). CONCLUSION: Limited EST plus LBD was an effective and safe procedure for removing choledocholithiasis in patients with PAD. However, some types of PAD should be managed with caution. | Hyung Wook Kim Dae Hwan Kang Cheol Woong Choi Jong Hwan Park Jin Ho Lee Min Dae Kim Il Doo Kim Ki Tae Yoon Mong Cho Ung Bae Jeon Suk Kim Chang Won Kim Jun Woo Lee | 2010 | World Journal of Gastroenterology2010,16,34: | 26 |
| 2 | Gastric cancer surgery in cirrhotic patients: Result of gastrectomy with D2 lymph node dissection显示文摘AIM: To explore the feasibility of performing gastrectomy with D2 lymphadenectomy in gastric cancer patients with liver cirrhosis.METHODS: A total of 7 178 patients were admitted with a diagnosis of liver cirrhosis from January 1993 to December 2003. We reviewed the records of 142 patients who were diagnosed with liver cirrhosis and gastric adenocarcinoma during the same period. Gastrectomy with D2 lymph node dissection for carcinoma of the stomach was performed in 94 patients with histologically proven hepatic cirrhosis.RESULTS: All but 12 patients were classified as Child's class A. Only 35 patients (37.2%) were diagnosed with cirrhosis before operation. Seventy-three patients underwent a subtotal gastrectomy (77.7%) and 21 patients (22.3%)underwent a total gastrectomy, each with D2 or more lymph node dissection. Two patients (3.8%) who had prophylactic intra-operative drain placement, died of postoperative complications from hepatorenal failure with intractable ascites. Thirty-seven patients (39.4%) experienced postoperative complications. The extent of gastric resection did not influence the morbidity whereas serum aspartate aminotransferase level (P = 0.011) and transfusion did (P= 0.008). The most common postoperative complication was ascites (13.9%) followed by wound infection (10.6%).CONCLUSION: We concluded that the presence of compensated cirrhosis, i.e. Child class A, is not a contraindication against gastrectomy with D2 or more lymph node dissection, when curative resection for gastric cancer is possible. Hepatic reserve and meticulous hemostasis are the likely determinants of operative prognosis. | Jun Ho Lee Junuk Kim Jae Ho Cheong Woo Jin Hyung Seung Ho Choi Sung Hoon Noh | 2005 | World Journal of Gastroenterology2005,11,30: | 25 |

| 4 | Biopathologic features and clinical significance of micrometatasis in the lymph node of early gastric cancer显示文摘AIM: To evaluate the biopathologic features and clinical significance of nodal micrometastasis(MI) in early gastric cancer(EGC).METHODS: Among 1022 EGC patients who underwent gastrectomy with lymphadenectomy of D1 + β or more from March 2001 to December 2005 at the Korean National Cancer Center, available nodal metastasis was found in 90 p T1N1 patients. Nodal metastasis was confirmed by immunohistochemistry(IHC) with cytokeratin and patients were classified into MI and macrometastasis(MA) groups based on the main tumor burden according to the 6th International Union Against Cancer/American Joint Committee on Cancer staging system; the main tumor burden with a diameter of greater than 0.2 mm but no greater than 2 mm as MI, and greater than 2 mm as MA of the representative metastatic node. Proliferative and apoptotic activities of the primary tumor and the nodal metastasis were measured by IHC with Ki-67 and terminal deoxynucleotidyl transferase d UTP nick end labeling, respectively. Biopathologic and clinical features of the patients were analyzed and compared between MI and MA groups. Patients with recurrence were compared with those without recurrence to identify risk factors for recurrence.RESULTS: Thirty-seven patients showed MI and the other 53 patients revealed MA in the lymph node; the incidence of patients with MI and MA was 41.1% and 58.9%. The main tumor burden was 0.9 and 4.6 mm in the representative metastatic node, respectively. Japanese N2 stations were more frequently involved in MA group(20.9%) than in MI group(10.3%) butthe difference was not statistically different(P = 0.338). Proliferative and apoptotic activities of MI were decreased than those of MA(26.7% vs 40.5%, P = 0.004 and 1.0% vs 3.0%, P < 0.001, respectively). However, nodal MI in the current study showed a relatively high proliferative activity and an equivalent apoptotic activity compared to other cancers in the previously published studies. Recurrence was observed in 6 patients during the mean follow up period of 87.6 ± 26.2 mo. The recurrence was significantly associated with the presence of MA(P = 0.041) and lymphovascular invasion of the primary tumor(P = 0.032).CONCLUSION: Lymphadenectomy of D1 + β or more might be necessary in patients with MI in sentinel node to prevent recurrence by clearing MI involving Japanese N2 station. | Min Jung Jo Ji Yeon Park Joon Seon Song Myeong-Cherl Kook Keun Won Ryu Soo-Jeong Cho Jun Ho Lee Byung-Ho Nam Eun Kyung Hong Il Ju Choi Young-Woo Kim | 2015 | World Journal of Gastroenterology2015,21,2: | 9 |

| 7 | Clinical significance and risk factors of postembolization fever in patients with hepatocellular carcinoma显示文摘AIM:To investigate tumor response and survival in patients with postembolization fever(PEF) and to determine the risk factors for PEF.METHODS:Four hundred forty-three hepatocellular carcinoma(HCC) patients who underwent the first session of transcatheter arterial chemoembolization(TACE) between January 2005 and December 2009 were analyzed retrospectively.PEF was defined as a body temperature greater than 38.0 ℃ that developed within 3 d of TACE without evidence of infection.The tumor progression-free interval was defined as the interval from the first TACE to the second TACE based on mRECIST criteria.Clinical staging was based on the American Joint Committee on Cancer tumor,node,metastases(TNM) classification of malignant tumors.All patients were admitted before their 1 st TACE treatment,and blood samples were obtained from all patients before and after treatment.Clinicoradiological variables and host-related variables were compared between two groups:patients with PEF vs patients without PEF.Additionally,variables related to 20-mo mortality and tumor progression-free survival were analyzed.RESULTS:The study population comprised 370(85.4%) men and 73(14.6%) women with a mean age of 62.29 ± 10.35 years.A total of 1836 TACE sessions were conducted in 443 patients,and each patient received between 1 and 27(mean:4.14 ± 3.57) TACE sessions.The mean follow-up duration was 22.23 ± 19.6 mo(range:0-81 mo).PEF developed in 117 patients(26.41%) at the time of the first TACE session.PEF was not associated with 20-mo survival(P = 0.524) or computed tomography(CT) response(P = 0.413) in a univariate analysis.A univariate analysis further indicated that diffuse-type HCC(P = 0.021),large tumor size(≥ 5 cm)(P = 0.046),lipiodol dose(≥ 7 mL,P = 0.001),poor blood glucose control(P = 0.034),alanine aminotransferase(ALT) value after TACE(P = 0.004) and C-reactive protein(CRP) value after TACE(P = 0.036) served as possible risk factors correlated with PEF.The ALT value after TACE(P = 0.021) and lipiodol dose over 7 mL(P = 0.011) were independent risk factors for PEF in the multivariate analysis.For the 20-mo survival,poor blood sugar control(P < 0.001),portal vein thrombosis(P = 0.001),favorable CT response after TACE(P < 0.001),initial aspartate aminotransferase(P = 0.02),initial CRP(P = 0.042),tumor size(P < 0.001),TNM stage(P < 0.001) and lipiodol dose(P < 0.001) were possible risk factors in the univariate analysis.Tumor size(P = 0.03),poor blood sugar control(P = 0.043),and portal vein thrombosis(P = 0.031) were significant predictors of survival in the multivariate analysis.Furthermore,the tumor progression-free interval was closely associated with CRP > 1 mg/dL(P = 0.003),tumor size > 5 cm(P < 0.001),tumor type(poorly defined)(P < 0.001),and lipiodol dose(> 7 mL,P < 0.001).CONCLUSION:PEF has no impact on survival at 20 mo or radiologic response.However,the ALT level after TACE and the lipiodol dose represent significant risk factors for PEF. | Chung Hwan Jun Ho Seok Ki Hoon Ki Lee Kang Jin Park Seon Young Park Sung Bum Cho Chang Hwan Park Young Eun Joo Hyun Soo Kim Sung Kyu Choi Jong Sun Rew | 2013 | World Journal of Gastroenterology2013,19,2: | 7 |
| 8 | Outcome of transarterial chemoembolization-based multi-modal treatment in patients with unresectable hepatocellular carcinoma显示文摘AIM:To investigate the efficacy and safety of transarterial chemoembolization(TACE)-based multimodal treatment in patients with large hepatocellular carcinoma(HCC).METHODS:A total of 146 consecutive patients were included in the analysis,and their medical records and radiological data were reviewed retrospectively.RESULTS:In total,119 patients received TACE-based multi-modal treatments,and the remaining 27 received conservative management.Overall survival(P<0.001)and objective tumor response(P=0.003)were significantly better in the treatment group than in the conservative group.After subgroup analysis,survival benefits were observed not only in the multi-modal treatment group compared with the TACE-only group(P=0.002)but also in the surgical treatment group compared with the loco-regional treatment-only group(P<0.001).Multivariate analysis identified tumor stage(P<0.001)and tumor type(P=0.009)as two independent pre-treatment factors for survival.After adjusting for significant pre-treatment prognostic factors,objective response(P<0.001),surgical treatment(P=0.009),and multi-modal treatment(P=0.002)were identified as independent post-treatment prognostic factors.CONCLUSION:TACE-based multi-modal treatments were safe and more beneficial than conservative management.Salvage surgery after successful downstaging resultedin long-term survival in patients with large,unresectable HCC. | Do Seon Song Soon Woo Nam Si Hyun Bae Jin Dong Kim Jeong Won Jang Myeong Jun Song Sung Won Lee Hee Yeon Kim Young Joon Lee Ho Jong Chun Young Kyoung You Jong Young Choi Seung Kew Yoon | 2015 | World Journal of Gastroenterology2015,21,8: | 7 |
| 9 | 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 |
| 10 | Hwangryunhaedoktang exerts anti-inflammation on LPS-induced NO production by suppressing MAPK and NF-κB activation in RAW264.7 macrophages显示文摘OBJECTIVE: This study aimed to evaluate whether Hwangryunhaedoktang(HHT), a herbal compound, has an inhibitory effect on lipopolysaccharide(LPS)-induced inflammation in RAW264.7 macrophages.METHODS: The effects of HHT were evaluated by confirming nitric oxide(NO) production and expression of inducible NO synthase(iN OS) and mitogen-activated protein kinases(MAPKs) in LPS-stimulated RAW264.7 macrophages via the Griess assay, Western blotting, and real-time reverse transcription quantitative polymerase chain reaction. Western blot analyses and luciferase assays were used to evaluate whether HHT has an effect on the phosphorylation and translocation of nuclear factor-κB(NF-κB). The secretion and expression of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) were determined via enzyme-linked immunosorbent assay and Western blot analyses.RESULTS: HHT suppressed LPS-induced NO production and expression of iN OS in a dose-dependent manner. Additionally, MAPKs activation was also attenuated via inhibition of phosphorylation of extracellular signal-regulated kinases 1/2, c-Jun N-terminal kinase and p38 which were related to inflammatory pathway. Furthermore, HHT also effectively attenuated NF-κB activation and its translocation to the nucleus, a process that is closely linked to inflammation. LPS normally induced the expression of inflammatory cytokines such as TNF-α and IL-6, but the secretion and expression of TNF-α and IL-6 were significantly attenuated by pretreating the cells with HHT.CONCLUSION: HHT suppressed LPS-induced NO production by blocking the activation of NF-κB and MAPK signaling pathways in RAW264.7 macrophages. Furthermore, HHT may have an anti-inflammatory effect by suppressing the LPS-induced secretion of TNF-α and IL-6. Therefore, the traditional herbal formula HHT might be a useful potential therapeutic agent for inflammation. | Byung Hyuk Han Yun Jung Lee Jung Joo Yoon Eun Sik Choi Seung Namgung Xian Jun Jin Da Hye Jeong Dae Gill Kang Ho Sub Lee | 2017 | Journal of Integrative Medicine2017,15,4: | 5 |

| 12 | Decellularized sciatic nerve matrix as a biodegradable conduit for peripheral nerve regeneration显示文摘The use of autologous nerve grafts remains the gold standard for treating nerve defects, but current nerve repair techniques are limited by donor tissue availability and morbidity associated with tissue loss. Recently, the use of conduits in nerve injury repair, made possible by tissue engineering, has shown therapeutic potential. We manufactured a biodegradable, collagen-based nerve conduit containing decellularized sciatic nerve matrix and compared this with a silicone conduit for peripheral nerve regeneration using a rat model. The collagen-based conduit contains nerve growth factor, brain-derived neurotrophic factor, and laminin, as demonstrated by enzyme-linked immunosorbent assay. Scanning electron microscopy images showed that the collagen-based conduit had an outer wall to prevent scar tissue infiltration and a porous inner structure to allow axonal growth. Rats that were implanted with the collagen-based conduit to bridge a sciatic nerve defect experienced significantly improved motor and sensory nerve functions and greatly enhanced nerve regeneration compared with rats in the sham control group and the silicone conduit group. Our results suggest that the biodegradable collagen-based nerve conduit is more effective for peripheral nerve regeneration than the silicone conduit. | Jongbae Choi Jun Ho Kim Ji Wook Jang Hyun Jung Kim Sung Hoon Choi Sung Won Kwon | 2018 | Neural Regeneration Research2018,13,10: | 5 |

| 16 | Multi-directionally wrinkle-able textile OLEDs for clothing-type displays显示文摘A clothing-type wearable display can be utilized in fashion,bio-healthcare,and safety industries as well as smart textiles for the internet of things(IoTs)and wearable devices.In response to this trend,we demonstrate a textile display that can endure the active movements of a human body.It can be applied to any kind of textile,and is durable against conditions such as rain,sweat,and washing.As a key technology for realizing the multi-directional wrinkle-able textile display,we fabricated a stress-lowering textile platform with an ultrathin planarization layer replicated from the flat surface of glass.An elastomeric strain buffer for reducing mechanical stress is also inserted into the textile platform.Here,organic light-emitting diodes(OLEDs)with red,green and blue color,thin film transistors(TFTs)fabricated at a low temperature below 150℃,and a washable encapsulation layer blocking both gas and liquid were demonstrated on the textile platform. | Seungyeop Choi Woosung Jo Yongmin Jeon Seonil Kwon Jeong Hyun Kwon Young Hyun Son Junmo Kim Jun Hong Park Hyuncheol Kim Ho Seung Lee Minwoo Nam Eun Gyo Jeong Jeong Bin Shin Taek-Soo Kim Kyung Cheol Choi | 2020 | npj Flexible Electronics2020,4,1: | 3 |
| 17 | Generation of induced secretome from adipose-derived stem cells specialized for disease-specific treatment:An experimental mouse model显示文摘BACKGROUND Recently,the exclusive use of mesenchymal stem cell(MSC)-secreted molecules,named as the secretome,have been evaluated for overcoming the limitations of cell-based therapy while maintaining its advantages.AIM To improve cell-free therapy by adding disease-specificity through stimulation of MSCs using disease-causing materials.METHODS We collected the secretory materials(named as inducers)released from AML12 hepatocytes that had been pretreated with thioacetamide(TAA)and generated the TAA-induced secretome(TAA-isecretome)after stimulating adipose-derived stem cells with the inducers.The TAA-isecretome was intravenously administered to mice with TAA-induced hepatic failure and those with partial hepatectomy.RESULTS TAA-isecretome infusion showed higher therapeutic potential in terms of(1)restoring disorganized hepatic tissue to normal tissue;(2)inhibiting proinflammatory cytokines(interleukin-6 and tumor necrosis factor-α);and(3)reducing abnormally elevated liver enzymes(aspartate aminotransferase and alanine aminotransferase)compared to the naïve secretome infusion in mice with TAA-induced hepatic failure.However,the TAA-isecretome showed inferior therapeutic potential for restoring hepatic function in partially hepatectomized mice.Proteomic analysis of TAA-isecretome identified that antioxidant processes were the most predominant enriched biological networks of the proteins exclusively identified in the TAA-isecretome.In addition,peroxiredoxin-1,a potent antioxidant protein,was found to be one of representative components of TAA-isecretome and played a central role in the protection of TAA-induced hepatic injury.CONCLUSION Appropriate stimulation of adipose-derived stem cells with TAA led to the production of a secretome enriched with proteins,especially peroxiredoxin-1,with higher antioxidant activity.Our results suggest that appropriate stimulation of MSCs with pathogenic agents can lead to the production of a secretome specialized for protecting against the pathogen.This approach is expected to open a new way of developing various specific therapeutics based on the high plasticity and responsiveness of MSCs. | Ok-Hee Kim Ha-Eun Hong Haeyeon Seo Bong Jun Kwak Ho Joong Choi Kee-Hwan Kim Joseph Ahn Sang Chul Lee Say-June Kim | 2020 | World Journal of Stem Cells2020,12,1: | 2 |
