| 1 | Clinical implications of fatty pancreas:Correlations between fatty pancreas and metabolic syndrome显示文摘AIM:To investigate the clinical implications of lipid deposition in the pancreas(fatty pancreas). METHODS:The subjects of this study were 293 patients who had undergone abdominal computed tomography(CT)and sonography.Fatty pancreas was diagnosed by sonographic findings and subdivided into mild,moderate,and severe fatty pancreas groups comparing to the retroperitoneal fat echogenicity. RESULTS:Fatty pancreas was associated with higher levels for visceral fat,waist circumference,aspartate aminotransferase(AST),alanine aminotransferase (ALT),total cholesterol,triglyceride,high density lipoprotein,free fatty acid,γ-GTP,insulin,and the homeostasis model assessment of insulin resistance (HOMA-IR)than the control group(P<0.05).HOMAIR,visceral fat,triglyceride,and ALT also tended to increase with the degree of fat deposition in the pancreas on sonography.In a multivariate logistic regression analysis,HOMA-IR,visceral fat,and ALT level were independently related to fatty pancreas after adjustment for age,body mass index,and lipid profile.The incidence of metabolic syndrome in the fatty pancreas group was significantly higher than in the control group,and the numbers of metabolic syndrome parameters were significantly higher in the fatty pancreas group(P<0.05).CONCLUSION:Sonographic fatty pancrease showed higher insulin resistance,visceral fat area,triglyceride, and ALT levels than normal pancreases.Fatty pancreas also showed a strong correlation with metabolic syndrome. | Jun Seok Lee Sang Heum Kim Dae Won Jun Jee Hye Han Eun Chul Jang Ji Young Park Byung Kwan Son Seong Hwan Kim Yoon Ju Jo Young Sook Park Yong Soo Kim | 2009 | World Journal of Gastroenterology2009,15,15: | 40 |
| 2 | CXC chemokines and chemokine receptors in gastric cancer: From basic findings towards therapeutic targeting显示文摘Gastric cancer is the fourth most common cancer,and the second-highest cause of cancer-related deaths worldwide.Despite extensive research to identify novel diagnostic and therapeutic agents,patients with advanced gastric cancer suffer from a poor quality of life and poor prognosis,and treatment is dependent mainly on conventional cytotoxic chemotherapy.To improve the quality of life and survival of gastric cancer patients,a better understanding of the underlying molecular pathologies,and their application towards the development of novel targeted therapies,is urgently needed.Chemokines are a group of small proteins associated with cytoskeletal rearrangements,the directional migration of several cell types during development and physiology,and the host immune response via interactions with G-protein coupled receptors.There is also growing evidence to suggest that chemokines not only play a role in the immune system,but are also involved in the development and progression of tumors.In gastric cancer,CXC chemokines and chemokine receptors regulate the trafficking of cells in and out of the tumor microenvironment.CXC chemokines and their receptors can also directly influence tumorigenesis by modulating tumor transformation,survival,growth,invasion and metastasis,as well as indirectly by regulating angiogenesis,and tumor-leukocyte interactions.In this review,we will focus on the roles of CXC chemokines and their receptors in the development,progression,and metastasis of gastric tumors,and discuss their therapeutic potential for gastric cancer. | Hyo Jin Lee Ik-Chan Song Hwan-Jung Yun Deog-Yeon Jo Samyong Kim | 2014 | World Journal of Gastroenterology2014,20,7: | 25 |
| 3 | Therapeutic potential of Gastrodia elata Blume for the treatment of Alzheimer's disease显示文摘Several studies have demonstrated that the Chinese herb Gastrodia elata Blume can protect against amyloid beta-peptide (Aβ)-induced cell death. To investigate the possible therapeutic effects of Gastrodia elata Blume on Alzheimer's disease, we established a rat model of Alzheimer's disease by injecting Aβ 25-35 into bilateral hippocampi. These rats were intragastrically administered 500 or 1 000 mg/kg Gastrodia elata Blume per day for 52 consecutive days. Morris water maze tests showed that Gastrodia elata Blume treatment significantly improved the spatial memory of Alzheimer's disease rats. Congo red staining revealed that Gastrodia elata Blume significantly reduced the number of amyloid deposits in the hippocampus of these rats. Western blot analysis showed that choline acetyltransferase expression in the medial septum and hippocampus was significantly increased by the treatment of Gastrodia elata Blume,while Ellman method showed significant decrease in the activity of acetylcholinesterase in all three regions (prefrontal cortex,medial septum and hippocampus). These findings suggest that long-term administration of Gastrodia elata Blume has therapeutic potential for Alzheimer's disease. | Guang-Biao Huang Tong Zhao Sushma Shrestha Muna Hong-Mei Jin Jong-Il Park Kyu-Sik Jo Bo-Hee Lee Soo-Wan Chae Sun-Young Kim Soo-Hyun Park Eun-Ock Park Eun-Kyung Choi Young-Chul Chung | 2013 | Neural Regeneration Research2013,8,12: | 21 |
| 4 | Benefit of neoadjuvant concurrent chemoradiotherapy for locally advanced perihilar cholangiocarcinoma显示文摘AIM To clarify the role of neoadjuvant concurrent chemoradiotherapy(NACCRT) followed by surgical resection for localized or locally advanced perihilar cholangiocarcinoma(CCA).METHODS We retrospectively reviewed 57 patients who underwent surgical resection with or without NACCRT for perihilar CCA; 12 patients received NACCRT and 45 patients did not received NACCRT. Patients with locally advanced perihilar CCA requiring NACCRT were defined as follows:(1) a mass involving unilateral branches of the portal vein or hepatic artery with insufficient volume of the anticipated remnant lobe; or(2) an infiltrating mass in the main portal vein that was too long for reconstruction, identified at preoperative staging. RESULTS The median disease-free survival(DFS) durations of the neoadjuvant and non-neoadjuvant CCRT groups were26.0 and 15.1 mo, respectively(P = 0.91). The median overall survival(OS) durations of the neoadjuvant and non-neoadjuvant CCRT groups were 32.9 and 27.1 mo, respectively(P = 0.26). The NACCRT group showed a downstaging tendency compared to the non-NACCRT group as compared with the tumor stage confirmed by histological examination after surgery and the tumor stage confirmed by imaging test at the time of diagnosis(P = 0.01). CONCLUSION NACCRT does not prolong DFS and OS in localized or locally advanced perihilar CCA. However, NACCRT may allow tumor downstaging and improve tumor resectability. | Jang Han Jung Hyun Jik Lee Hee Seung Lee Jung Hyun Jo In Rae Cho Moon Jae Chung Jeong Youp Park Seung Woo Park Si Young Song Seungmin Bang | 2017 | World Journal of Gastroenterology2017,23,18: | 21 |
| 5 | Colonoscopy evaluation after short-term anti-tuberculosis treatment in nonspecific ulcers on the ileocecal area显示文摘AIM: To evaluate the eff icacy of colonoscopy follow-up after short-term anti-tuberculosis treatment in patients with nonspecific ulcers on ileocecal areas being suspicious of tuberculous colitis. METHODS: We prospectively analyzed the colonoscopic fi ndings before and after short term anti- tuberculosis treatment in 18 patients with nonspecifi c ulcers on the ileocecal area and compared them with 7 patients of confi rmed tuberculous colitis by acid-fast bacilli or caseating granuloma on colonic biopsy. RESULTS: Mean duration for short-term follow- up was 107.3 d with combined chemotherapy containing isoniazid, rifampicin, ethambutol and pyrazinamide. Seven patients with tuberculous colitis showed complete healing of active ulcers after short- term medication. After short-term anti-tuberculosis treatment, follow-up colonoscopy findings devided 18 patients with nonspecific ulcers into two groups by ulcer state. One is the 'suspicious tuberculous colitis group' showing healing of ulcers and erosions and another is the 'suspicious inflammatory bowel disease group' showing active ulcers with or without aggravation of the lesion. Finally, all 9 of the 'suspicious tuberculous colitis group' were diagnosed as tuberculous colitis showing no recurrence of ulcers after termination of 9 mo of anti-tuberculosis medication. Patients of the 'suspicious inflammatorybowel disease group' were f inally diagnosed as Crohn's disease or nonspecifi c colonic ulcers during long-term follow up. CONCLUSION: Follow-up colonoscopy shows a healing stage ulcer or scarring change without an active ulcer with just 2 mo to 3 mo of medication in patients with tuberculous colitis. Colonoscopy follow-up after short term anti-tuberculosis trial in patients with nonspecif ic ulcers on the ileocecal area is valuable in making early differential diagnosis of tuberculous colitis. | Young Sook Park Dae Won Jun Seong Hwan Kim Han Hyo Lee Yun Ju Jo Moon Hee Song Nam In Kim Jun Seok Lee | 2008 | World Journal of Gastroenterology2008,14,32: | 14 |
| 6 | Understanding the physical metallurgy of the CoCrFeMnNi high-entropy alloy:an atomistic simulation study显示文摘Although high-entropy alloys(HEAs)are attracting interest,the physical metallurgical mechanisms related to their properties have mostly not been clarified,and this limits wider industrial applications,in addition to the high alloy costs.We clarify the physical metallurgical reasons for the materials phenomena(sluggish diffusion and micro-twining at cryogenic temperatures)and investigate the effect of individual elements on solid solution hardening for the equiatomic CoCrFeMnNi HEA based on atomistic simulations(Monte Carlo,molecular dynamics and molecular statics).A significant number of stable vacant lattice sites with high migration energy barriers exists and is thought to cause the sluggish diffusion.We predict that the hexagonal close-packed(hcp)structure is more stable than the face-centered cubic(fcc)structure at 0 K,which we propose as the fundamental reason for the micro-twinning at cryogenic temperatures.The alloying effect on the critical resolved shear stress(CRSS)is well predicted by the atomistic simulation,used for a design of non-equiatomic fcc HEAs with improved strength,and is experimentally verified.This study demonstrates the applicability of the proposed atomistic approach combined with a thermodynamic calculation technique to a computational design of advanced HEAs. | Won-Mi Choi Yong Hee Jo Seok Su Sohn Sunghak Lee Byeong-Joo Lee | 2018 | npj Computational Materials2018,,1: | 11 |
| 7 | The modulation of radiation-induced cell death by genistein in K562 cells:Activation of thymidine kinase 1显示文摘Ionizing radiation is one of the most effective tools in cancer therapy. In a previous study, we reported that protein tyrosine kinase (PTK) inhibitors modulate the radiation responses in the human chronic myelogenous leukemia (CML)cell line K562. The receptor tyrosine kinase inhibitor, genistein, delayed radiation-induced cell death, while non-recepter tyrosine kinase inhibitor, herbimycin A (HMA) enhances radiation-induced apoptosis. In this study, we focused on the modulation of radiation-induced cell death by genistein and performed PCR-select suppression subtractive hybridization(SSH) to understand its molecular mechanism. We identified human thymidine kinase 1 (TK1), which is cell cycle regulatory gene and confirmed expression of TK1 mRNA by Northern blot analysis. Expression of TK1 mRNA and TK 1enzymatic activity were parallel in their increase and decrease. TK1 is involved in G1-S phase transition of cell cycle progression. In cell cycle analysis, we showed that radiation induced G2 arrest in K562 cells but it was not able to sustain. However, the addition of genistein to irradiated cells sustained a prolonged G2 arrest up to 120 h. In addition,the expression of cell cycle-related proteins, cyclin A and cyclin B 1, provided the evidences of G1/S progression and G2-arrest, and their relationship with TK1 in cells treated with radiation and genistein. These results suggest that the activation of TK1 may be critical to modulate the radiation-induced cell death and cell cycle progression in irradiated K562 cells. | Min Ho JEONG Young Hee JIN Eun Young KANG Wol Soon JO Hwan Tae PARK Jae Dong LEE Yeo Jin YOO Soo Jin JEONG | 2004 | Cell Research2004,14,4: | 10 |
| 8 | LAMOST Experiment for Galactic Understanding and Exploration (LEGUE)——The survey's science plan显示文摘We describe the current plans for a spectroscopic survey of millions of stars in the Milky Way galaxy using the Guo Shou Jing Telescope (GSJT, formerly called the Large sky Area Multi-Object fiber Spectroscopic Telescope - LAMOST). The survey will obtain spectra for 2.5 million stars brighter than r < 19 during dark/grey time, and 5 million stars brighter than r < 17 or J < 16 on nights that are moonlit or have low transparency. The survey will begin in the fall of 2012, and will run for at least four years. The telescope's design constrains the optimal declination range for observations to 10 < δ < 50 , and site conditions lead to an emphasis on stars in the direction of the Galactic anticenter. The survey is divided into three parts with different target selection strategies: disk, anticenter, and spheroid. The resulting dataset will be used to study the merger history of the Milky Way, the substructure and evolution of the disks, the nature of the first generation of stars through identification of the lowest metallicity stars, and star formation through study of open clusters and OB associations. Detailed design of the LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) survey will be completed in summer 2012, after a review of the results of the pilot survey. | Li-Cai Deng Heidi Jo Newberg Chao Liu Jeffrey L.

| 9 | 含垂直裂纹的厚热障涂层的热稳定性及力学性能(英文)显示文摘采用循环热暴露及热震试验研究含或不含垂直裂纹的厚热障涂层的热稳定性和失效机制。先采用空气等离子喷涂技术在基体表面制备150μm厚的连接涂层,再在该涂层上采用空气等离子喷涂技术制备2000μm厚的热障涂层。含或不含垂直裂纹的热障涂层的粘附强度分别为24.7和11.0 MPa,表明含垂直裂纹的热障涂层的界面稳定性更高。循环热暴露及热震试验表明其热稳定性更高。含或不含垂直裂纹的热障涂层的硬度分别为6.6和5.3GPa,经循环热暴露试验后分别升高至9.5和5.5 GPa。实验表明上层涂层中垂直裂纹的存在有利于延长热障涂层高温环境的寿命。 | Zhe LU Min-Sik KIM Sang-Won MYOUNG Je-Hyun LEE Yeon-Gil JUNG In-Soo KIM Chang-Yong JO | 2014 | Transactions of Nonferrous Metals Society of China2014,24,S1: | 9 |
| 10 | 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 |
| 11 | Characteristics of and risk factors for colorectal neoplasms in young adults in a screening population显示文摘AIM: To investigate prevalence and risk factors for colorectal neoplasms in adults aged < 50 years, for whom screening is not recommended.METHODS: This cross-sectional study compared prevalence and characteristics of colorectal and advanced adenomas in patients aged < 50 years who underwent colonoscopy screening with subjects aged ≥ 50 years. To evaluate risk factors for colorectal and advanced adenoma in young adults, we used multivariable logistic regression models. Colorectal neoplasm characteristics were evaluated and compared with those in older patients.RESULTS: Among 2819 patients included, prevalences of colorectal adenoma and advanced adenoma were 19.7% and 1.5%, respectively. As patient age increased, so did the prevalence of colorectal neoplasm. However, prevalence of advanced adenoma did not differ between age-groups 45-49 years and ≥ 50 years(OR = 0.43, 95%CI: 0.17-1.07, P = 0.070). In younger age-group(< 50 years), colorectal adenoma was significantly associated with older age, waist circumference(OR = 1.72, 95%CI: 1.15-2.55, P = 0.008), and current smoking(OR = 1.60, 95%CI: 1.07-2.41, P = 0.023). Alcohol consumption was an independent risk factor for colorectal advanced adenoma(OR = 3.69, 95%CI: 1.08-12.54, P = 0.037). Multiple neoplasms and large neoplasms(≥ 1 cm) were more prevalent in subjects ≥ 50 years.CONCLUSION: Current screening strategies for colorectal cancer may need to be amended to account for patient age, especially in young subjects with abdominal obesity, current smoking and alcohol consumption. | Seung Eun Lee Hee Bum Jo Won Gun Kwack Yun Jin Jeong Yeo-Jin Yoon Hyoun Woo Kang | 2016 | World Journal of Gastroenterology2016,22,10: | 8 |

| 13 | Asymptomatic lymphangioma involving the spleen and retroperitoneum in adults显示文摘Lymphangioma,a benign neoplasm of the lymphatic system,is common in children but rare in adults.Its clinical manifestations include abdominal pain,nausea, vomiting and a palpable mass.However,abdominal sonography or abdominal computed tomography(CT) scan can also incidentally reveal lymphangioma.A larger or symptomatic lymphangioma is treated with total resection to prevent recurrence,infection,torsion and enlargement.Although lymphangioma rarely becomes malignant,its prognosis is generally good. We report a cystic lymphangioma of the spleen and retroperitoneum,which was incidentally found in a 56-year-old man who was hospitalized due to a colon mass.Physical examination showed no specific findings.Abdominal CT revealed a 5.7 cm,non-enhanced multilobulated cystic mass with multiple septa in the spleen and a 10 cm lobulated cystic mass in the paraaortic area.Splenectomy and retroperitoneal resection of the cystic mass were conducted.The endotheliumof splenic and retroperitoneal cyst was immunohisto- chemically stained with D2-40 antibody.The patient was finally diagnosed with splenic cystic and retroperitoneal cavernous lymphangioma. | Sook Hee Chung Young Sook Park Yun Ju Jo Seong Hwan Kim Dae Won Jun Byoung Kwan Son Jun Young Jung Dae Hyun Baek Dong Hee Kim Yoon Young Jung Won Mi Lee | 2009 | World Journal of Gastroenterology2009,15,44: | 7 |
| 14 | Behavior of CaO and Calcium in pure Magnesium显示文摘Mg alloys exhibit a number of good properties such as low density, good castability and high specific strength. However, molten Mg and Mg alloys are ignited without the melt protective gases during melting and casting process due to their high reactivity. The purpose of this study is to investigate effects of Ca and CaO on pure Mg through microstructure observation, ignition test and phase analysis. With increasing Ca and CaO contents, the ignition resistance of Ca or CaO added pure Mg is increased and the grains are refined. As results of XRD and EDS, CaO is reduced to Ca in CaO added pure Mg. Mg2Ca phase is formed even in 0.1 wt.%CaO added pure Mg by reduction mechanism, while Mg2Ca phase is formed over 1.35 wt.% Ca added pure Mg. | HA Seong-Ho LEE Jin-Kyu JO Hyung-Ho JUNG Seung-Boo KIM Shae K. | 2006 | Rare Metals2006,25,z2: | 7 |
| 15 | Clinicopathologic and molecular features associated with patient age in gastric cancer显示文摘AIM: To compare characteristics and prognosis of gastric cancer based on age.METHODS: A retrospective study was conducted on clinical and molecular data from patients(n =1658) with confirmed cases of gastric cancer in Seoul National University Bundang Hospital(Seoul, South Korea) from 2003 to 2010 after exclusion of patients diagnosed with lymphoma, gastrointestinal stromal tumor, and metastatic cancer in the stomach. DNA was isolated from tumor and adjacent normal tissue,and a set of five markers was amplified by polymerase chain reaction to assess microsatellite instability(MSI). MSI was categorized as high, low, or stable if ≥ 2, 1, or 0 markers, respectively, had changed.Immunohistochemistry was performed on tissue sections to detect levels of expression of p53, human epidermal growth factor receptor(HER)-2, and epidermal growth factor receptor. Statistical analysis of clinical and molecular data was performed to assess prognosis based on the stratification of patients by age(≤ 45 and> 45 years).RESULTS: Among the 1658 gastric cancer patients, the number of patients with an age ≤ 45 years was 202(12.2%; 38.9 ± 0.4 years) and the number of patients> 45 years was 1456(87.8%; 64.1 ± 0.3 years).Analyses revealed that females were predominant inthe younger group(P < 0.001). Gastric cancers in the younger patients exhibited more aggressive features and were at a more advanced stage than those in older patients. Precancerous lesions, such as atrophic gastritis and intestinal metaplasia, were observed less frequently in the older than in the younger group(P < 0.001). Molecular characteristics, including overexpression of p53(P < 0.001), overexpression of HER-2(P = 0.006), and MSI(P = 0.006), were less frequent in gastric cancer of younger patients. Cancer related mortality was higher in younger patients(P= 0.048), but this difference was not significant after adjusting for the stage of cancer.CONCLUSION: Gastric cancer is distinguishable between younger and older patients based on both clinicopathologic and molecular features, but stage is the most important predictor of prognosis. | Ji Yeon Seo Eun Hyo Jin Hyun Jin Jo Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim Hyun Chae Jung Dong Ho Lee | 2015 | World Journal of Gastroenterology2015,21,22: | 7 |

| 18 | Comparison of efficacy and safety between standard-dose and modified-dose FOLFIRINOX as a first-line treatment of pancreatic cancer显示文摘AIM To directly compare the efficacy and toxicity of standarddose FOLFIRINOX(sFOLFIRINOX) and modified-dose FOLFIRINOX(mFOLFIRINOX, 75% of standard-dose) for pancreatic cancer.METHODS One hundred and thirty pancreatic cancer patients who received sFOLFIRINOX(n = 88) or mFOLFIRINOX(n = 42) as their first-line chemotherapy from January 2013 to July 2017 were retrospectively reviewed. For efficacy analysis, the objective response rate(ORR),disease control rate(DCR), progression-free survival(PFS), and overall survival(OS) were evaluated and compared using Pearson's chi-square test, Kaplan-Meier plot and log-rank test. The adverse events(AEs) were evaluated, and severe(≥ grade 3) AEs rates of the two groups were compared for toxicity analysis.RESULTS The mFOLFIRINOX group included more female patients(30.7% vs 57.1%; P = 0.004) and older patients [age(median), 57 vs 63.5; P = 0.018] than the sFOLFIRINOX group. In the efficacy analysis, the ORR and DCR were not significantly different between the two groups(ORR: 39.8% vs 35.7%; P = 0.656; DCR: 80.7% vs 83.3%; P = 0.716). The median PFS and OS were also not different between the groups(PFS: 8.7 mo vs 8.1 mo, P = 0.272; OS: 13.9 mo vs 13.7 mo, P = 0.476). In the safety analysis with severe AEs, the rates of neutropenia(83.0% vs 66.7%; P = 0.044), anorexia(48.9% vs 28.6%; P = 0.029) and diarrhea(13.6% vs 0.0%; P = 0.009) were markedly lower in the mFOLFIRINOX group.CONCLUSION m FOLFIRINOX showed comparable efficacy but better safety compared to sFOLFIRINOX. If clinically necessary, initiating FOLFIRINOX with 75% of the standard-dose can alleviate toxicity concerns without compromising efficacy. | Huapyong Kang Jung Hyun Jo Hee Seung Lee Moon Jae Chung Seungmin Bang Seung Woo Park Si Young Song Jeong Youp Park | 2018 | World Journal of Gastrointestinal Oncology2018,10,11: | 6 |
| 19 | Hepatobiliary scintigraphy for detecting biliary strictures after living donor liver transplantation显示文摘AIM:To investigate the diagnostic accuracy of hepatobiliary scintigraphy(HBS) in detecting biliary strictures in living donor liver transplantation(LDLT) patients.METHODS:We retrospectively reviewed 104 adult LDLT recipients of the right hepatic lobe with duct-toduct anastomosis,who underwent HBS and cholangiography.The HBS results were categorized as normal,parenchymal dysfunction,biliary obstruction,or bile leakage without re-interpretation.The presence of biliary strictures was determined by percutaneous cholangiography or endoscopic retrograde cholangiopancreatography(ERCP).RESULTS:In 89 patients with biliary strictures,HBS showed biliary obstruction in 50 and no obstruction in 39,for a sensitivity of 56.2%.Of 15 patients with no biliary strictures,HBS showed no obstruction in 11,for a specificity of 73.3%.The positive predictive value(PPV) was 92.6%(50/54) and the negative predictive value(NPV) was 22%(11/50).We also analyzed the diagnostic accuracy of the change in bile duct size.The sensitivity,NPV,specificity,and PPV were 65.2%,27.9%,80% and 95%,respectively.CONCLUSION:The absence of biliary obstruction on HBS is not reliable.Thus,when post-LDLT biliary strictures are suspected,early ERCP may be considered. | Yu Jin Kim Kyu Taek Lee Young Cheol Jo Kwang Hyuck Lee Jong Kyun Lee Jae-Won Joh Choon Hyuck David Kwon | 2011 | World Journal of Gastroenterology2011,17,21: | 6 |
