1Clinical 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 2009World Journal of Gastroenterology2009,15,15:40
2Bedside index for severity in acute pancreatitis:comparison with other scoring systems in predicting severity and organ failure显示文摘BACKGROUND:The early identification of severe acute pancreatitis is important for the management and for improving outcomes.The bedside index for severity in acute pancreatitis(BISAP)has been considered as an accurate method for risk stratification in patients with acute pancreatitis.This study aimed to evaluate the comparative usefulness of the BISAP.METHODS:We retrospectively analyzed 303 patients with acute pancreatitis diagnosed at our hospital from March 2007to December 2010.BISAP,APACHE-II,Ranson criteria,and CT severity index(CTSI)of all patients were calculated.We stratified the number of patiants with severe pancreatitis,pancreatic necrosis,and organ failure as well as the number of deaths by BISAP score.We used the area under the receiveroperating curve(AUC)to compare BISAP with other scoring systems,C-reactive protein(CRP),hematocrit,and body mass index(BMI)with regard to prediction of severe acute pancreatitis,necrosis,organ failure,and death.RESULTS:Of the 303 patiants,31(10.2%)were classified as having severe acute pancreatitis.Organ failure occurred in 23(7.6%)patients,pancreatic necrosis in 40(13.2%),and death in6(2.0%).A BISAP score of 2 was a statistically significant cutoff value for the diagnosis of severe acute pancreatitis,organ failure,and mortality.AUCs for BISAP predicting severe pancreatitis and death were 0.80 and 0.86,respectively,which were similar to those for APACHE-II(0.80,0.87)and Ranson criteria(0.74,0.74)and greater than AUCs for CTSI(0.67,0.42).The AUC for organ failure predicted by BISAP,APACHE-II,Ranson criteria,and CTSI was 0.93,0.95,0.84 and 0.57,respectively.AUCs for BISAP predicting severity,organ failure,and death were greater than those for CRP(0.69,0.80,0.72),hematocrit(0.45,0.35,0.14),and BMI(0.41,0.47,0.17).CONCLUSION:The BISAP predicts severity,death,and especially organ failure in acute pancreatitis as well as APACHE-II does and better than Ranson criteria,CTSI,CRP,hematocrit,and BMI.Ji Young Park Tae Joo Jeon Tae Hwan Ha Jin Tae Hwang Dong Hyun Sinn Tae-Hoon Oh Won Chang Shin Won-Choong 2013Hepatobiliary & Pancreatic Diseases International2013,12,6:33
3Histologic characteristics of gastric polyps in Korea: Emphasis on discrepancy between endoscopic forceps biopsy and endoscopic mucosal resection specimen显示文摘瞄准:在朝鲜人口调查胃的息肉的组织学的特征。方法:我们与胃的息肉考察了内视镜的相片和病人的医药记录通过 2003 年 2 月从 1996 年 4 月经历了内视镜的粘膜切除术。结果:从 74 个病人的 85 胃的息肉的一个总数被考察。Male-to-female 比率是 1:1.96。吝啬的年龄是 59.9 +/- 10.8 年。多重息肉在 10.8% 被观察。胃的息肉最经常发生在窦(58.8%) 。resected 标本上的病理学的结果如下:管状腺瘤 45.9% ,增生的息肉 31.8% ,煽动性的息肉 9.4% ,错构瘤 3.5% ,底的腺息肉 2.4% , tubulovillous 腺瘤 2.4% ,腺癌 2.4% ,发育异常 1.1% ,并且粘膜 pseudolipomatosis 1.1% 。在 resected 标本的内视镜的活体检视和病理之间的差异率是 27.1% 。在息肉和词语索引率的尺寸之间没有关系。结论:在在内视镜的钳活体检视和 resected 标本之间的 histologic 调查结果有可观的差异。全部息肉的组织学的评论的途径应该被执行,特别当一个腺瘤被怀疑时。Won Jae Yoon Dong Ho Lee Yong Jin Jung Ji Bong Jeong Ji Won Kim Byeong Gwan Kim Kook Lae Lee Kwang Hyuck Lee Young Soo Park Jin-Hyeok Hwang Jin-Wook Kim Nayoung Kim Jun Kyu Lee Hyun Chae Jung Yong Bum Yoon In Sung Song 2006World Journal of Gastroenterology2006,12,25:19
4Recurrence after endoscopic piecemeal mucosal resection for large sessile colorectal polyps显示文摘AIM: To evaluate the safety and outcomes of endoscopic piecemeal mucosal resection (EPMR) for large sessile colorectal polyps. METHODS: The patients enrolled in this study were 47 patients with 50 large sessile polyps (diameter, 2 cm or greater) who underwent EPMR using a submucosal saline injection technique between December 2002 and October 2005. All medical records, including characteristics of the patients and polyps, complications, and recurrences, were retrospectively reviewed. The first follow-up endoscopic examination was performed at 3-6 mo after initial endoscopic resection, and the second at 12 mo postEPMR. Subsequent surveillance colonoscopic examinations were individualized, taking risk factors into account. RESULTS: The patients were 23 men and 24 women,with a mean age of 60 years. Mean polyp size was 30.1 mm. Of 50 polyps identified, 34 (68%) were benign and 16 (32%) were malignant. There were 6 (12%) cases with EPMR-related bleeding: 5 intra-procedural and 1 early post-procedural bleeding. All bleeding episodes were managed by endoscopic clipping or argon beam coagulation. There were no perforations. Recurrence was identified in 5 cases (12.2%): 4 local recurrences detected at 3 mo post-EPMR and 1 local recurrence detected at 14 mo post-EPMR. The recurrence rate after EPMR was 3.1% for benign polyps and 33.3% for malignant polyps (P < 0.05). Median follow-up time was 37 mo. CONCLUSION: EPMR is safe, but should be applied carefully in malignant polyps. Close follow-up endoscopic examinations are necessary for early detection of recurrence.Guh Jung Seo Dae Kyung Sohn Kyung Su Han Chang Won Hong Byung Chang Kim Ji Won Park Hyo Seong Choi Hee Jin Chang Jae Hwan Oh 2010World Journal of Gastroenterology2010,16,22:17
5Optimal biliary drainage for inoperable Klatskin's tumor based on Bismuth type显示文摘AIM: To investigate differences in the effects of biliary drainage procedures in patients with inoperable Klatskin’s tumor based on Bismuth type, considering endoscopic retrograde biliary drainage (ERBD), external percutaneous transhepatic biliary drainage (EPTBD) and internal biliary stenting via the PTBD tract (IPTBD). METHODS: The initial success rate, cumulative patency rate, and complication rate were compared retrospectively, according to the Bismuth type and ERBD, EPTBD, and IPTBD. Patency was defined as the duration for adequate initial bile drainage or to the point of the patient’s death associated with inadequate drainage. RESULTS: One hundred thirty-four patients (93 men, 41 women; 21 Bismuth type Ⅱ, 47 Ⅲ, 66 Ⅳ; 34 ERBD, 66 EPTBD, 34 IPTBD) were recruited. There were no differences in demographics among the groups. Adequate initial relief of jaundice was achieved in 91% of patients without a significant difference in the results among different procedures or Bismuth types. The cumulative patency rates for ERBD and IPTBD were better than those for EPTBD with Bismuth type Ⅲ. IPTBD provided an excellent response for Bismuth type Ⅳ. However, there was no difference in the patency rate among drainage procedures for Bismuth type Ⅱ. Procedure-related cholangitis occurred less frequently with EPTBD than with ERBD and IPTBD. CONCLUSION: ERBD is recommended as the first- line drainage procedure for the palliation of jaundice in patients with inoperable Klatskin’s tumor of Bismuth type Ⅱ or Ⅲ, but IPTBD is the best option for Bismuth type Ⅳ.Sang Hyub Lee Joo Kyung Park Won Jae Yoon Jun Kyu Lee Ji Kon Ryu Yong Bum Yoon Yong-Tae Kim 2007World Journal of Gastroenterology2007,13,29:17
6Effects of Flower Buds Extract of Tussilago farfara on Focal Cerebral Ischemia in Rats and Inflammatory Response in BV2 Microglia显示文摘Objective: To investigate the effects of the flower buds extract of Tussilago farfara Linné(Farfarae Flos; FF) on focal cerebral ischemia through regulation of inflammatory responses in activated microglia. Methods: Brain ischemia was induced in Sprague-Dawley rats by a transient middle cerebral artery occlusion(t MCAO) for 90 min and reperfusion for 24 h. Twenty rats were randomly divided into 4 groups(n=5 per group): normal, t MCAO-induced ischemic control, t MCAO plus FF extract 300 mg/kg-treated, and t MCAO plus MK-801 1 mg/kg-treated as reference drug. FF extract(300 mg/kg, p.o.) or MK-801(1 mg/kg, i.p.) was administered after reperfusion. Brain infarction was measured by 2,3,5,-triphenyltetrazolium chloride staining. Neuronal damage was observed by haematoxylin eosin, Nissl staining and immunohistochemistry using anti-neuronal nuclei(Neu N), anti-glial fibril ary acidic protein(GFAP), and antiCD11 b/c(OX42) antibodies in ischemic brain. The expressions of inducible nitric oxide synthase(i NOS), tumor necrosis factor(TNF-α), and hypoxia-inducible factor-1 a(HIF-1α) were determined by Western blot. BV2 microglial cel s were treated with FF extract or its main bioactive compound, tussilagone with or without lipopolysaccharide(LPS). Nitric oxide(NO) production was measured in culture medium by Griess assay. The expressions of i NOS, COX-2 and pro-inflammatory cytokines mRNA were analyzed by reverse transcription-polymerase chain reaction. The expression of i NOS, and COX-2 proteins, the phosphorylation of ERK1/2, JNK, and p38 MAPK and the nuclear expression of NF-κB p65 in BV2 cells were determined by Western blot. Results: FF extract significantly decreased brain infarctions in ischemic rats(P<0.01). The neuronal death and the microglia/astrocytes activation in ischemic brains were inhibited by FF extract. FF extract also suppressed i NOS, TNF-α, and HIF-1α expression in ischemic brains. FF extract(0.2 and 0.5 mg/m L, P<0.01) and tussilagone 20 and 50 μmol/L, P<0.01) significantly decreased LPS-induced NO production in BV2 microglia through downregulation of i NOS m RNA and protein expression. FF extract and tussilagone significantly inhibited LPS-induced expression of TNF-α, IL-1β, and IL-6 m RNA, and also suppressed the phosphorylation of ERK1/2, JNK and p38 MAPK and the nuclear expression of NF-κB in a dosedependent manner. Conclusion: FF extract has a neuroprotective effect in ischemic stroke by the decrease of brain infarction, and the inhibition of neuronal death and microglial activation-mediated inflammatory responses.Ji Hye Hwang Vinoth Kumar R Seok Yong Kang Hyo Won Jung Yong-Ki Park 2018Chinese Journal of Integrative Medicine2018,24,11:13
7Management of entecavir-resistant chronic hepatitis B with adefovir-based combination therapies显示文摘AIM: To evaluate the long-term efficacy adefovir(ADV)-based combination therapies in entecavir(ETV)-resistant chronic hepatitis B(CHB) patients. METHODS: F i fty CHB pat ient s wi t h genotypic resistance to ETV at 13 medical centers in South Korea were included for the analysis. All the patients received rescue therapy with the combination of ADV plus ETV(ADV/ETV,n = 23) or ADV plus lamivudine(LMV)(ADV/LMV,n = 27) for more than 12 mo. Patients were monitored at least every 3-4 mo during ADV-based combination therapy by clinical examination as well as biochemical and virological assessments. Hepatitis B virus(HBV) DNA levels were measured by realtime PCR and logarithmically transformed for analysis. Cumulative rates of virologic response(VR; HBV DNA < 20 IU/m L) were calculated using the Kaplan-Meier method,and the difference was determined by a logrank test. Multivariate logistic regression and Cox proportional hazards models were used to identify independent risk factors significantly associated with short-term and long-term VR,respectively.RESULTS: Baseline median HBV DNA levels were 5.53(2.81-7.63) log10 IU/m L. The most commonly observed ETV genotypic mutation sites were rt184 and rt202. Patients were treated for a median of 27(12-45) mo. Overall,cumulative VR rates at 6,12,24,and 36 mo were 26%,36%,45%,and 68%,respectively. Patients treated with the ADV/ETV combination showed higher cumulative VR rates(35%,43%,65%,and 76%,respectively) than those with the ADV/LAM combination(18%,30%,30%,and 62%,respectively; P = 0.048). In the multivariate analysis,low baseline HBV DNA levels(< 5.2 log10 IU/m L) and initial virologic response at 3 mo(IVR-3; HBV DNA < 3.3 log10 IU/m L after 3 mo) were independent predictive factors for VR. Patients with favorable predictors achieved cumulative VR rates up to 90% at 36 mo. During the same period,the cumulative incidence of virologic breakthrough was as low as 6% in patients with the both favorable predictors.CONCLUSION: If tenofovir is not available,ADV/ETV combination could be considered in ETV-resistant patients with low HBV DNA titers,and may becontinued if IVR-3 is achieved.Hyoung Su Kim Hyung Joon Yim Myoung Kuk Jang Ji Won Park Sang Jun Suh Yeon Seok Seo Ji Hoon Kim Bo Hyun Kim Sang Jong Park Sae Hwan Lee Sang Gyune Kim Young Seok Kim Jung Il Lee Jin-Woo Lee In Hee Kim Tae Yeob Kim Jin-Wook Kim Sook-Hyang Jeong Young Kul Jung Hana Park Seong Gyu Hwang 2015World Journal of Gastroenterology2015,21,38:13
8Pretreated 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 2017Neural Regeneration Research2017,12,2:9
9Biopathologic 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 2015World Journal of Gastroenterology2015,21,2:9

13PD-1 blockade-unresponsive human tumor-infiltrating CD8^(+)T cells are marked by loss of CD28 expression and rescued by IL-15显示文摘Blockade of programmed death-1(PD-1)reinvigorates exhausted CD8^(+)T cells,resulting in tumor regression in cancer patients.Recently,reinvigoration of exhausted CD8^(+)T cells following PD-1 blockade was shown to be CD28-dependent in mouse models.Herein,we examined the role of CD28 in anti-PD-1 antibody-induced human T cell reinvigoration using tumor-infiltrating CD8^(+)T cells(CD8^(+)TILs)obtained from non-small-cell lung cancer patients.Single-cell analysis demonstrated a distinct expression pattern of CD28 between mouse and human CD8^(+)TILs.Furthermore,we found that human CD28^(+)CD8^(+)but not CD28^(–)CD8^(+)TILs responded to PD-1 blockade irrespective of B7/CD28 blockade,indicating that CD28 costimulation in human CD8^(+)TILs is dispensable for PD-1 blockade-induced reinvigoration and that loss of CD28 expression serves as a marker of anti-PD-1 antibody-unresponsive CD8^(+)TILs.Transcriptionally and phenotypically,PD-1 blockade-unresponsive human CD28^(–)PD-1^(+)CD8^(+)TILs exhibited characteristics of terminally exhausted CD8^(+)T cells with low TCF1 expression.Notably,CD28^(–)PD-1^(+)CD8^(+)TILs had preserved machinery to respond to IL-15,and IL-15 treatment enhanced the proliferation of CD28^(–)PD-1^(+)CD8^(+)TILs as well as CD28^(+)PD-1^(+)CD8^(+)TILs.Taken together,these results show that loss of CD28 expression is a marker of PD-1 blockade-unresponsive human CD8^(+)TILs with a TCF1–signature and provide mechanistic insights into combining IL-15 with anti-PD-1 antibodies.Kyung Hwan Kim Hong Kwan Kim Hyung-Don Kim Chang Gon Kim Hoyoung Lee Ji Won Han Seong Jin Choi Seongju Jeong Minwoo Jeon Hyunglae Kim Jiae Koh Bo Mi Ku Su-Hyung Park Myung-Ju Ahn Eui-Cheol Shin 2021Cellular & Molecular Immunology2021,18,2:6
14Signet-ring cell carcinoma arising from a fundic gland polyp in the stomach显示文摘Fundic gland polyps(FGPs)are currently the most common type of gastric polyps and are usually benign.However,although rare,gastric adenocarcinoma of FGP has been recently proposed as a new variant of gastric adenocarcinoma.Here we report the first case of a49-year-old woman with focal signet ring cell carcinoma that arose from an FGP of the stomach.The tumor was completely excised by endoscopic snare polypectomy.FGPs should therefore be evaluated for malignant changes although they occur rarely,if the FGP has an erosive or irregular surface.Yong Seol Jeong Sung Eun Kim Mi-Jung Kwon Jae Yong Seo Hyun Lim Ji Won Park Ho Suk Kang Sung Hoon Moon Jong Hyuk Kim Choong Kee Park 2014World Journal of Gastroenterology2014,20,47:6
15Pretreated 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 2019Neural Regeneration Research2019,14,9:6
16Ampullary neuroendocrine tumor diagnosed by endoscopic papillectomy in previously confirmed ampullary adenoma显示文摘Ampullary adenoma is a common indication for endoscopic papillectomy. Ampullary neuroendocrine tumor(NET) is a rare disease for which complete surgical resection is the treatment of choice. However, because of the morbidity and mortality associated with surgical resection, endoscopic papillectomy is increasingly used in selected cases of low grade, with no metastasis and no invasion of the pancreatic or bile duct. Also, confirmed and complete endoscopic resection of ampullary NET accompanied by adenoma has not been reported to date. We report herein a rare case of an ampullary NET accompanied with adenoma, which was successfully and completely resected via endoscopic papillectomy. Prior to papillectomy, this case was diagnosed as an ampullary adenoma.Seoung Ho Lee Tae Hoon Lee Si-Hyong Jang Chi Young Choi Won Myung Lee Ji Hey Min Hyun Deuk Cho Sang-Heum Park 2016World Journal of Gastroenterology2016,22,13:6
17T cell epitopes in SARS-CoV-2 proteins are substantially conserved in the Omicron variant显示文摘In November 2021,the Omicron variant(B.1.1.529)emerged and was designated a variant of concern(VOC)by the World Health Organization.Recently,Omicron was reported to extensively escape neutralizing antibodies elicited by COVID-19 vaccination or natural infection[1,2,3].However,whether Omicron evades the T cell immunity elicited by COVID-19 vaccination or natural infection remains to be elucidated.To address this issue,we analyzed the amino acid sequences of T cell epitopes identified from the original SARS-CoV-2 strain(Wuhan-Hu-1)in the Omicron variant(hCoV-19/South Africa/CERI-KRISP-K032284/2021).Seong Jin Choi Dong-Uk Kim Ji Yun Noh Sangwoo Kim Su-Hyung Park Hye Won Jeong Eui-Cheol Shin 2022Cellular & Molecular Immunology2022,19,3:5
18Nonalcoholic fatty liver disease is associated with coronary artery disease in Koreans显示文摘AIM:To investigate whether nonalcoholic fatty liver disease(NAFLD)affects coronary artery disease(CAD)and identify candidate mediators.METHODS:Patients who underwent coronary angiography were consecutively recruited.The patients were classified into four groups by coronary artery stenosis:A,insignificant;B,one-vessel disease;C,two-vessel disease;and D,three-vessel disease.Abdominal ultrasonography was performed to determine the presence of a fatty liver and categorize by grade:0,no evidence;1,mild;2,moderate;and 3,severe.We measured not only known CAD risk factors,but also serum insulin,HOMA-index,adiponectin,interleukin-6,tumor necrosis factor-αand high-sensitivity C-reactive protein levels.RESULTS:Of the 134 patients who met the inclusion criteria,82(61.2%)had ultrasonographically diagnosed NAFLD.Among the 46 patients with CAD,37(80.4%)had evidence of a fatty liver.The two groups(A vs B-D)were significantly different in terms of age,total cholesterol,triglycerides,low-density lipoprotein levels and fatty liver.Coronary artery stenosis was strongly associated with fatty liver in a grade-dependent manner(P=0.025).In binary logistic regression,NAFLD was a significant independent predictor of CAD(P=0.03,OR=1.685;95%CI:1.051-2.702).Among the candidate mediators,the serum adiponectin level showed a trend toward lowering based on CAD progression(P=0.071).CONCLUSION:NAFLD is an independent risk factor for CAD in a grade-dependent manner.Moreover,adiponectin might be related to the pathogenesis of NAFLD.Dae Hee Choi Sung Joon Lee Chang Don Kang Myoung Ok Park Dong Wook Choi Tae Suk Kim Wonho Lee Byung Ryul Cho Yong Hoon Kim Bong-ki Lee Dong Ryeol Ryu Ji Won Lee 2013World Journal of Gastroenterology2013,19,38:5
