| 1 | Comparison of the efficacy and safety of sedation between dexmedetomidine-remifentanil and propofol-remifentanil during endoscopic submucosal dissection显示文摘AIM: To compare the efficacy and safety of sedation protocols for endoscopic submucosal dissection(ESD) between dexmedetomidine-remifentanil and propofolremifentanil.METHODS: Fifty-nine patients scheduled for ESD were randomly allocated into a dexmedetomidineremifentanil(DR) group or a propofol-remifentanil(PR) group. To control patient anxiety, dexmedetomidine or propofol was infused to maintain a score of 4-5 on the Modified Observer's Assessment of Alertness/Sedation scale. Remifentanil was infused continuously at a rate of 6 μg/kg per hour in both groups. The ease of advancing the scope into the throat, gastric motility grading, and satisfaction of the endoscopist and patient were assessed. Hemodynamic variables and hypoxemic events were compared to evaluate patient safety.RESULTS: Demographic data were comparable between the groups. The hemodynamic variables and pulse oximetry values were stable during the procedure in both groups despite a lower heart rate in the DR group. No oxygen desaturation events occurred in either group. Although advancing the scope into the throat was easier in the PR group('very easy' 24.1% vs 56.7%, P = 0.010), gastric motility was moresuppressed in the DR group('no + mild' 96.6% vs 73.3%, P = 0.013). The endoscopists felt that the procedure was more favorable in the DR group('very good + good' 100% vs 86.7%, P = 0.042), whereas patient satisfaction scores were comparable between the groups. En bloc resection was performed 100% of the time in both groups, and the complete resection rate was 94.4% in the DR group and 100% in the PR group(P = 0.477). CONCLUSION: The efficacy and safety of dexmedetomidine and remifentanil were comparable to propofol and remifentanil during ESD. However, the endoscopists favored dexmedetomidine perhaps due to lower gastric motility. | Namo Kim Young-Chul Yoo Sang Kil Lee Hyunzu Kim Hyang Mi Ju Kyeong Tae Min | 2015 | World Journal of Gastroenterology2015，21，12： | 25 |

| 3 | Neoadjuvant chemoradiotherapy followed by D2 gastrectomy in locally advanced gastric cancer显示文摘AIM:To investigate the efficacy of neoadjuvant chemoradiotherapy(NACRT) for resectability of locally advanced gastric cancer(LAGC).METHODS:Between November 2007 and January 2014,29 patients with LAGC(clinically T3 with distal esophagus invasion/T4 or bulky regional node metastasis) that were treated with NACRT followed by D2 gastrectomy were included in this study.Resectability was evaluated with radiologic and endoscopic exams before and after NACRT.Using threedimensional conformal radiotherapy,patients received 45 Gy,with a daily dose of 1.8 Gy.The entire tumor extent and the regional metastatic lymph nodes were included in the gross tumor volume.Patients presenting with a resectable tumor after NACRT received a total or subtotal gastrectomy with D2 dissection.The pathologic tumor response was evaluated using Japanese Gastric Cancer Association histologic evaluation criteria.Postoperative morbidity was evaluated using the National Cancer Institute-Common Terminology Criteria for Adverse Events version 4.0.Overall survival(OS) and progression-free survival(PFS) rates were estimated using a Kaplan-Meier analysis and compared using the log-rank test.RESULTS:All patients were assessed as unresectable cases.Twenty-four patients(24/29; 82.8%) showed LAGC on positron emission tomography-computed tomography(CT) and contrast-enhanced CT,whereas four patients(4/29; 13.8%) with vague invasion orabutment to an adjacent organ underwent diagnostic laparoscopy.One patient(1/29; 3.4%),initially assessed as a resectable case,underwent an 'open and closure' after the tumor was found to be unresectable.Abutment to an adjacent organ(34.5%) was the most common reason for NACRT.The clinical response rate one month after NACRT was 44.8%.After NACRT,69%(20/29) of patients had a resectable tumor.Of the 20 patients with a resectable tumor,18 patients(62.1%) underwent a D2 gastrectomy.The R0 resection rate was 94.4% and two patients(2/18; 11.1%) showed a complete response.The median follow-up duration was 13.5 mo.The one-year OS and PFS rates were 72.4 and 48.9%,respectively.The one-year OS,PFS,local failure-free survival,and distant metastasis-free survival were higher in patients with a resectable tumor after NACRT(P < 0.001,P < 0.001,P < 0.001,and P =0.078,respectively).No grade 3-4 late treatment-related toxicities or postoperative mortalities were observed.CONCLUSION:NACRT with D2 gastrectomy showed a high rate of R0 resection and promising local control,which may increase the R0 resection opportunity resulting in survival benefit. | Mi Sun Kim Joon Seok Lim Woo Jin Hyung Yong Chan Lee Sun Young Rha Ki Chang Keum Woong Sub Koom | 2015 | World Journal of Gastroenterology2015，21，9： | 15 |
| 4 | Brain-derived neurotrophic factor mediates macrophage migration inhibitory factor to protect neurons against oxygen-glucose deprivation显示文摘Macrophage migration inhibitory factor(MIF)is a chemokine that plays an essential role in immune system function.Previous studies suggested that MIF protects neurons in ischemic conditions.However,few studies are reported on the role of MIF in neurological recovery after ischemic stroke.The purpose of this study is to identify the molecular mechanism of neuroprotection mediated by MIF.Human neuroblastoma cells were incubated in Dulbecco’s modified Eagle’s medium under oxygen-glucose deprivation(OGD)for 4 hours and then returned to normal aerobic environment for reperfusion(OGD/R).30 ng/mL MIF recombinant(30 ng/mL)or ISO-1(MIF antagonist;50μM)was administered to human neuroblastoma cells.Then cell cultures were assigned to one of four groups:control,OGD/R,OGD/R with MIF,OGD/R with ISO-1.Cell viability was analyzed using WST-1 assay.Expression levels of brain-derived neurotrophic factor(BDNF),microtubule-associated protein 2(MAP2),Caspase-3,Bcl2,and Bax were detected by western blot assay and immunocytochemistry in each group to measure apoptotic activity.WST-1 assay results revealed that compared to the OGD/R group,cell survival rate was significantly higher in the OGD/R with MIF group and lower in the OGD/R with ISO-1 group.Western blot assay and immunocytochemistry results revealed that expression levels of BDNF,Bcl2,and MAP2 were significantly higher,and expression levels of Caspase-3 and Bax were significantly lower in the MIF group than in the OGD/R group.Expression levels of BDNF,Bcl2,and MAP2 were significantly lower,and expression levels of Caspase-3 and Bax were significantly higher in the ISO-1 group than in the OGD/R group.MIF administration promoted neuronal cell survival and induced high expression levels of BDNF,MAP2,and Bcl2(anti-apoptosis)and low expression levels of Caspase-3 and Bax(pro-apoptosis)in an OGD/R model.These results suggest that MIF administration is effective for inducing expression of BDNF and leads to neuroprotection of neuronal cells against hypoxic injury. | Su Hwan Bae Mi Ran Yoo Ye Yeong Kim In Kyung Hong Mi Hee Kim Seung Hak Lee Dae Yul Kim | 2020 | Neural Regeneration Research2020，15，8： | 11 |

| 6 | Toothpick impaction with sigmoid colon pseudodiverticulum formation successfully treated with colonoscopy显示文摘Foreign bodies in the colon are encountered with increasing frequency, but only sporadic reports concerning their management have appeared in the literature. While most ingested foreign bodies usually pass through the gastrointestinal tract uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal perforation and may even result in death. We report our experience with a patient with a sigmoid colon pseudodiverticulum formation, a complication of accidental ingestion of a toothpick that was diagnosed and successfully managed colonoscopically. | Youn Son Chung Yong Woo Chung Sun You Moon Su Mi Yoon Min-Jeong Kim Kyoung Oh Kim Cheol Hee Park Taeho Hahn Kyo-Sang Yoo Sang Hoon Park Jong Hyeok Kim Choong Kee Park | 2008 | World Journal of Gastroenterology2008，14，6： | 10 |
| 7 | Efficacy of early treatment with infliximab in pediatric Crohn’s disease显示文摘AIM: To investigate the effectiveness of early infliximab use for induction and maintenance therapy in pediatric Crohn’s disease. METHODS: We performed a retrospective chart review of 36 patients with Crohn’s disease. Ten patients (group A) were treated with mesalamine after induction therapy with oral prednisolone, and 13 patients (group B) were treated with azathioprine after induction therapy with oral prednisolone. Thirteen patients (group C) received infliximab and azathioprine for induction and maintenance therapy for the first year, and were treated with azathioprine after 1 year. All patients were followed for at least 24 mo. Efficacy was determined by the relapse rate using the pediatric Crohn’s disease activity index score in each group at 12 and 24 mo. RESULTS: At the 1 year follow-up, the relapse ratee, Mi Jin Kim, Hae Jeong Lee, Yon Ho Choe (23.1%, 3 of 13 patients) in group C was lower than that (61.5%, 8 of 13 patients) in group B (P = 0.047). At the 2 years follow-up, the relapse rate (38.5%, 5 of 13 patients) in group C was lower than that (76.9%, 10 of 13 patients) in group B (P = 0.047). Adverse events in group C were fewer than in groups A and B. CONCLUSION: Early induction with infliximab at diagnosis, known as 'top-down' therapy, was effective for reducing the relapse rate compared to conventional therapies for at least 2 years. | Jong Seung Lee Jee Hyun Lee Ji Hyuk Lee Hye Jin Lee Mi Jin Kim Hae Jeong Lee Yon Ho Choe | 2010 | World Journal of Gastroenterology2010，16，14： | 10 |
| 8 | Association of chronic viral hepatitis B with insulin resistance显示文摘AIM:To investigate the relationship between chronic viral hepatitis B(CVHB) and insulin resistance(IR) in Korean adults.METHODS:A total of 7880 adults(3851 men,4029 women) who underwent a comprehensive medical examination were enrolled in this study.Subjects diagnosed with either diabetes mellitus,or any other disorder that could influence their insulin sensitivity,were rejected.Anthropometry,metabolic risk factors,hepatitis B surface antigen,hepatitis B surface antibody,hepatitis B core antibody,fasting plasma glucose and insulin were measured for all subjects.Homeostasis model assessment(HOMA),quantitative insulin check index(QUICKI),and Mf fm index were used for determining insulin sensitivity.Each participant was categorized into a negative,recovery,or CVHB group.To compare variables between groups,a t-test and/or one-way analysis of variance were used.Partial correlation coefficients were computed to present the association between insulin resistance and other variables.Multiple logistic regression analysis was used to assess the independent association between CVHB and IR.RESULTS:The mean age of men and women were 48.9 and 48.6 years,respectively.Subjects in the CVHB group had significantly higher waist circumference [(86.0 ± 7.7 cm vs 87.3 ± 7.8 cm,P = 0.004 in men),(78.3 ± 8.6 cm vs 80.5 ± 8.5 cm,P < 0.001 in women)],cystatin C [(0.96 ± 0.15 mg/dL vs 1.02 ± 0.22 mg/dL,P < 0.001 in men),(0.84 ± 0.15 mg/dL vs 0.90 ± 0.16 mg/dL,P < 0.001 in women)],fasting insulin [(5.47 ± 3.38 U/mL vs 6.12 ± 4.62 U/mL,P < 0.001 in men),(4.57 ± 2.82 U/mL vs 5.06 ± 3.10 U/mL,P < 0.001 in women)] and HOMA index [(1.24 ± 0.86 vs 1.43 ± 1.24,P < 0.001 in men),(1.02 ± 0.76 vs 1.13 ± 0.87,P = 0.033 in women)] compared to control group.The HOMA index revealed a positive correlation with body mass index(BMI)(r = 0.378,P < 0.001),waist circumference(r =0.356,P < 0.001),percent body fat(r = 0.296,P < 0.001),systolic blood pressure(r = 0.202,P < 0.001),total cholesterol(r = 0.134,P < 0.001),triglycerides(r = 0.292,P < 0.001),cystatin C(r = 0.069,P < 0.001) and uric acid(r = 0.142,P < 0.001).The QUICKI index revealed a negative correlation with BMI(r =-0.254,P < 0.001),waist circumference(r = 0-0.243,P < 0.001),percent body fat(r =-0.217,P < 0.001),systolic blood pressure(r =-0.132,P < 0.001),total cholesterol(r =-0.106,P < 0.001),triglycerides(r =-0.205,P < 0.001),cystatin C(r =-0.044,P < 0.001) and uric acid(r =-0.096,P < 0.001).For subjects identified with IR,the odds ratio of an accompanying diagnosis of chronic hepatitis B was 1.534(95% CI:1.158-2.031,HOMA index criteria) or 1.566(95% CI:1.124-2.182,QUICKI criteria) after adjustment for age,gender,BMI,and amount of alcohol consumption.CONCLUSION:Our study demonstrates that CVHB is associated with IR.CVHB may need to be monitored for occurrence of IR and diabetes mellitus. | Jeong Gyu Lee Sangyeoup Lee Yun Jin Kim Byung Mann Cho Joo Sung Park Hyung Hoi Kim JaeHun Cheong Dong Wook Jeong Yu Hyun Lee Young Hye Cho Mi Jin Bae Eun Jung Choi | 2012 | World Journal of Gastroenterology2012，18，42： | 10 |

| 10 | Three-Tesla magnetic resonance elastography for hepatic fibrosis:Comparison with diffusion-weighted imaging and gadoxetic acid-enhanced magnetic resonance imaging显示文摘AIM:To evaluate the feasibility of 3-Tesla magnetic resonance elastography(MRE)for hepatic fibrosis and to compare that with diffusion-weighted imaging(DWI)and gadoxetic acid-enhanced magnetic resonance(MR)imaging.METHODS:Forty-two patients were included in the study.On MRE,mean stiffness values were measured on the elastograms in kilopascals.The apparent diffusion coefficient(ADC)of the liver was measured using DWI.On gadoxetic acid enhanced MR,the contrast enhancement index(CEI)was calculated as signal intensity(SI)post/SIpre,where SIpost is liver-to-muscle SI ratio on hepatobiliary phase images and SIpre is that on nonenhanced images.Correlation between aspartate aminotransferase to the platelet ratio index(APRI)and three MR parameters was assessed.Each MR parameter was compared between a hepatic fibrosis(HF)group and non-hepatic fibrosis(n HF)group.RESULTS:Liver stiffness showed strong positive correlation with APRI[Spearman correlation coeffiecient(r)=0.773,P<0.0001],while ADC and CEI showed weak or prominent negative correlation(r=-0.28 and-0.321,respectively).In the HF group,only liver stiffness showed strong correlation with APRI(r=0.731,P<0.0001).Liver stiffness,ADC,and APRI were significantly different between the HF group and n HF group.CONCLUSION:MRE at 3-Tesla could be a feasible method for the assessment of hepatic fibrosis. | Hee Sun Park Young Jun Kim Mi Hye Yu Won Hyeok Choe Sung Il Jung Hae Jeong Jeon | 2014 | World Journal of Gastroenterology2014，20，46： | 9 |
| 11 | Benign gallbladder diseases:Imaging techniques and tips for differentiating with malignant gallbladder diseases显示文摘Benign gallbladder diseases usually present with intraluminal lesions and localized or diffuse wall thickening.Intraluminal lesions of the gallbladder include gallstones,cholesterol polyps,adenomas,or sludge and polypoid type of gallbladder cancer must subsequently be excluded.Polyp size,stalk width,and enhancement intensity on contrast-enhanced ultrasound and degree of diffusion restriction may help differentiate cholesterol polyps and adenomas from gallbladder cancer.Localized gallbladder wall thickening is largely due to segmental or focal gallbladder adenomyomatosis,although infiltrative cancer may present similarly.Identification of Rokitansky-Aschoff sinuses is pivotal in diagnosing adenomyomatosis.The layered pattern,degree of enhancement,and integrity of the wall are imaging clues that help discriminate innocuous thickening from gallbladder cancer.High-resolution ultrasound is especially useful for analyzing the layering of gallbladder wall.A diffusely thickened wall is frequently seen in inflammatory processes of the gallbladder.Nevertheless,it is important to check for coexistent cancer in instances of acute cholecystitis.Ultrasound used alone is limited in evaluating complicated cholecystitis and often requires complementary computed tomography.In chronic cholecystitis,preservation of a two-layered wall and weak wall enhancement are diagnostic clues for excluding malignancy.Magnetic resonance imaging in conjunction with diffusion-weighted imaging helps to differentiate xathogranulomatous cholecystitis from gallbladder cancer by identifying the presence of fat and degree of diffusion restriction.Such distinctions require a familiarity with typical imaging features of various gallbladder diseases and an understanding of the roles that assorted imaging modalities play in gallbladder evaluations. | Mi Hye Yu Young Jun Kim Hee Sun Park Sung Il Jung | 2020 | World Journal of Gastroenterology2020，26，22： | 9 |
| 12 | Lycium barbarum polysaccharides related RAGE and Aβ levels in the retina of mice with acute ocular hypertension and promote maintenance of blood retinal barrier显示文摘Our previous study verified the protective effects of Lycium barbarum polysaccharides(LBP)on retinal neurons and blood vessels in acute ocular hypertension(AOH)mice.To investigate the effect of LBP on the reactivity of retinal glial cells,an AOH mouse model was established in one eye by maintaining ocular hypertension of 90 mm Hg for 60 minutes.Either LBP solution(1 mg/kg)or phosphate-buffered saline was administrated to the mice by gavage daily,starting 7 days before the AOH insult and continuing until the mice were sacrificed for specimen collection on day 4 post-insult.After AOH insult,increased numbers of astrocytes and microglia were observed,together with decreased expression of the following glial cell biomarkers in the retinal ganglion cells of AOH mice:glial fibrillary acidic protein,glutamine synthetase,aquaporin-4,S-100 proteins,ionized calcium-binding adaptor molecule 1,amyloid precursor protein and receptor of advanced glycosylation end-products.After intervention with LBP,the above changes were significantly reduced.Remarkably,morphological remodeling of blood vessel-associated retinal astrocytes,marked by glial fibrillary acidic protein,was also observed.These results,taken together,suggest that LBP regulated the production of amyloid-βand expression of receptor of advanced glycosylation end-products,as well as mediating the activity of retinal glial cells,which may lead to the promotion of better maintenance of the blood-retinal barrier and improved neuronal survival in AOH insult.This study was approved by the Committee for the Use of Live Animals in Teaching and Research(approval No.CULTRA-#1664-08). | Xue-Song Mi Qian Feng Amy Cheuk Yin Lo Raymond Chuen-Chung Chang Sookja Kim Chung Kwok-Fai So | 2020 | Neural Regeneration Research2020，15，12： | 8 |

| 14 | Esophageal subepithelial lesion diagnosed as malignant gastrointestinal neuroectodermal tumor显示文摘A 21-year-old male visited our hospital with a complaint of aggravating dysphagia and odynophagia for a few days.Esophagogastroduodenoscopy showed huge bulging mucosa with an intact surface causing luminal narrowing at 35 cm from the incisor teeth.Endoscopic ultrasonography showed an about 35 mm sized irregular margined in-homogenous hypoechoic lesion with an obscure layer of origin.Endoscopic ultrasonography fine needle aspiration revealed spindle cell proliferation without immunoreactivity for CD117,SMA,and cytokeratin.The patient underwent excision of the subepithelial lesion at the distal esophagus.On pathologic examination of the specimen,the tumor was composed of short fascicles of oval to spindle cells with eosinophilic and clear cytoplasm and vesicular nuclei.The tumor cells were positive for S-100 and SOX10and negative for CD117,SMA,HMB-45,melan-A,cytokeratin,and CD99.The split-apart signal was detected in EWSR1 on FISH,suggesting a malignant gastrointestinal neuroectodermal tumor.At the time of writing,the patient is on radiation therapy at the operated site of esophagus and doing well,with no recurrence for three months.Malignant gastrointestinal neuroectodermal tumor is a rare gastrointestinal tumor with features of clear cell sarcoma,without melanocytic differentiation,and shows a poor prognosis.This is the first reported case of malignant gastrointestinal neuroectodermal tumor arising as subepithelial lesion in the esophagus. | Sung Bum Kim Si Hyung Lee Mi Jin Gu | 2015 | World Journal of Gastroenterology2015，21，18： | 8 |
| 15 | Assessing significant fibrosis using imaging-based elastography in chronic hepatitis B patients: Pilot study显示文摘BACKGROUND Accurate detection of significant fibrosis(fibrosis stage 2 or higher on the METAVIR scale)is important especially for chronic hepatitis B(CHB)patients with high viral loads but with normal or mildly elevated alanine aminotransferase(ALT)levels because the presence of significant fibrosis is accepted as the indication for antiviral treatment.Liver biopsy is the reference standard for diagnosing significant fibrosis,but it is an invasive procedure.Consequently,noninvasive imaging-based measurements,such as magnetic resonance elastography(MRE)or two-dimensional shear-wave elastography(2DSWE),have been proposed for the quantitative assessment of liver fibrosis.AIM To explore MRE and 2D-SWE to identify fibrosis stage,and to compare their performance with that of serum-based indices.METHODS The study enrolled 63 treatment-na?ve CHB patients with high viral loads but with normal or mildly elevated ALT levels who underwent liver biopsy before a decision was made to initiate antiviral therapy.MRE and 2D-SWE were performed,and serum-based indices,such as FIB-4 and aspartate transaminase to platelet ratio index(APRI),were calculated.The diagnostic performances of MRE,2D-SWE,FIB-4,and APRI for assessing significant fibrosis(≥F2)and cirrhosis(F4)were evaluated with liver histology as the reference standard,using receiver operating characteristic analyses.RESULTS The liver fibrosis stage was F0/F1 in 19,F2 in 14,F3 in 14,and F4 in 16 patients,respectively.MRE significantly discriminated F2 from F0/1(P=0.022),whereas 2D-SWE showed a broad overlap in distinguishing those stages.MRE showed a higher correlation coefficient value with fibrosis stage than 2D-SWE with fibrosis stage(0.869 vs 0.649,Spearman test;P<0.001).Multivariate linear regression analyses showed that fibrosis stage was the only factor affecting the values of MRE(P<0.001),whereas body mass index(P=0.042)and fibrosis stage(P<0.001)were independent factors affecting 2D-SWE values.MRE performance for diagnosing significant fibrosis was better[area under the curve(AUC)=0.906,positive predictive value(PPV)97.3%,negative predictive value(NPV)69.2%]than that of FIB-4(AUC=0.697,P=0.002)and APRI(AUC=0.717,P=0.010),whereas the performance of 2D-SWE(AUC=0.843,PPV 86%,NPV 65%)was not significantly different from that of FIB-4 or APRI.CONCLUSION Compared to SWE,MRE might be more precise non-invasive assessment for depicting significant fibrosis and for making-decision to initiate antiviral-therapy in treatment-na?ve CHB patients with normal or mildly-elevated ALT levels. | Hee Sun Park Won Hyeok Choe Hye Seung Han Mi Hye Yu Young Jun Kim Sung Il Jung Jeong Han Kim So Young Kwon | 2019 | World Journal of Gastroenterology2019，25，25： | 7 |
| 16 | Risk prediction of hepatitis B virus-related hepatocellular carcinoma in the era of antiviral therapy显示文摘Hepatocellular carcinoma(HCC)is a grave primary liver cancer that has a limited therapeutic option because it is generally diagnosed later in an advanced stage due to its aggressive biologic behavior.The early detection of HCC has a great impact on the treatment efficacy and survival of patients at high risk for cancer.Potential host,environmental,and virus-related risk factors have been introduced.Hepatitis B virus(HBV)is a major cause of end-stage liver diseases such as liver cirrhosis or HCC in endemic areas,and its serologic or virologic status is considered an important risk factor.HCC risk prediction derived from the identification of major risk factors is necessary for providing adequate screening/surveillance strategies to high-risk individuals.Several risk prediction models for HBV-related HCC have been presented recently with simple,efficient,and readily available to use parameters applicable to average-or unknown-risk populations as well as high-risk individuals.Predictive scoring systems of risk estimation to assess HCC development can provide the way to an evidence-based clinical approach for cost-and effort-effective outcomes,capable of inducing a personalized surveillance program according to risk stratification.In this review,the concepts and perspectives of the risk prediction of HCC are discussed through the analysis of several risk prediction models of HBV-related HCC. | Il Han Song So Mi Kim Young Kwang Choo | 2013 | World Journal of Gastroenterology2013，19，47： | 7 |
| 17 | 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 |
| 18 | Differential 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 | 2013 | World Journal of Gastroenterology2013，19，40： | 6 |
| 19 | PD-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 | 2021 | Cellular & Molecular Immunology2021，18，2： | 6 |
