| 1 | 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 |
| 2 | Contrast-enhanced ultrasonography for the evaluation of liver fibrosis after biliary obstruction显示文摘AIM:To investigate perfusion change in contrastenhanced ultrasonography(CEUS) to evaluate liver fibrosis based on biliary obstruction using an animal model.METHODS:New Zealand white rabbits(3-4 kg) underwent bile duct ligation to form a biliary obstruction model.We performed liver CEUS and laboratory tests on the day before the operation(day 0) and every 7 postoperative days until the rabbits were sacrificed.After CEUS,signal intensity of liver parenchyma with a time-intensity curve was analyzed.Perfusion parameters were automatically calculated from regionof-interests,including peak signal intensity,mean transit time,area under the curve and time to peak.Histological grades of liver fibrosis were assessed according to the Metavir score system immediately after sacrifice.Generalized estimating equations were used to analyze the association between liver fibrosis grades and perfusion parameters for statistical analysis.The perfusion parameters were measured on the last day and the difference between day 0 and the last day were evaluated.RESULTS:From the nine rabbits,histological grades of liver fibrosis were grade 1 in one rabbit,grade 2 and 3 in three rabbits each,and grade 4 in two rabbits.Among the four CEUS parameters,only the peak signal intensity measured on the last day demonstrated a significant association with liver fibrosis grades(OR =1.392,95%CI:1.114-1.741,P =0.004).The difference in peak signal intensity between day 0 and the last dayalso demonstrated an association with liver fibrosis(OR =1.191,95%CI:0.999-1.419,P =0.051).The other parameters tested,including mean transit time,area under the curve,and time to peak,showed no significant correlation with liver fibrosis grades.CONCLUSION:This animal study demonstrates that CEUS can be used to evaluate liver fibrosis from biliary obstruction using peak signal intensity as a parameter. | Hyun Joo Shin Eun Young Chang Hye Sun Lee Jung Hwa Hong Gyuri Park Hyun Gi Kim Myung-Joon Kim Mi-Jung Lee | 2015 | World Journal of Gastroenterology2015，21，9： | 4 |
| 3 | A case of Clostridium difficile infection complicated by acute respiratory distress syndrome treated with fecal microbiota transplantation显示文摘Acute respiratory distress syndrome is a life-threatening disorder caused mainly by pneumonia.Clostridium difficile infection(CDI)is a common nosocomial diarrheal disease.Disruption of normal intestinal flora by antibiotics is the main risk factor for CDI.The use of broadspectrum antibiotics for serious medical conditions can make it difficult to treat CDI complicated by acute respiratory distress syndrome.Fecal microbiota transplantation is a highly effective treatment in patients with refractory CDI.Here we report on a patient with refractory CDI and acute respiratory distress syndrome caused by pneumonia who was treated with fecal microbiota transplantation. | Ji Eun Kim Tae-Geun Gweon Chang Dong Yeo Young-Seok Cho Gi Jun Kim Jae Young Kim Jong Wook Kim Hyunho Kim Hye Won Lee Taeseok Lim Hyoju Ham Hyun Jin Oh Yeongbok Lee Jaeho Byeon Sung Soo Park | 2014 | World Journal of Gastroenterology2014，20，35： | 3 |
| 4 | Relationship between early structural changes at cornea incision sites and surgical outcomes after phacoemulsification显示文摘AIM: To assess the early structural changes at clear corneal cataract incision sites and surgical outcomes using anterior segment optical coherence tomography(AS-OCT).METHODS: We evaluated 80 eyes of 59 patients who underwent phacoemulsification with a clear corneal incision. All incisions were evaluated 1 wk, 1, and 3 mo postoperatively using AS-OCT and analyzed regarding angle, length of the incision, maximal corneal thickness at the incision, and if present, corneal endothelial gap length and incision gap area. The patients were divided into two groups according to whether or not an endothelial gap was present at 1 wk postoperatively(endothelial gap, group 1;no endothelial gap, group 2). We analyzed the difference in patient and surgical factors between the two groups, and compared the surgical outcome and the refractive outcome.RESULTS: An endothelial gap was observed in 56(70.0%) of 80 eyes at 1 wk postoperatively but not at 3 mo postoperatively. The mean patient age was significantly higher in group 1 than in group 2. The longer the length of the corneal incision and the steeper the incision angle, the greater the length and area of the endothelial gap. In group 1, the mean change in mean keratometry of the anterior cornea was significantly greater than in group 2, and the spherical equivalent(SE) and mean numerical error indicated significant myopic changes at 1 wk postoperatively. CONCLUSION: The risk of an endothelial gap increases with patient age and a long corneal incision and steep incision angle. The presence of an endothelial gap aftersurgery may affect the early postoperative corneal curvature and SE. | Kyung Hyun Jin Tae Gi Kim | 2019 | International Journal of Ophthalmology(English edition)2019，12，7： | 3 |

| 6 | 3D-printed gelatin methacrylate (GelMA)/ silanated silica scaffold assisted by two-stage cooling system for hard tissue regeneration显示文摘Among many biomaterials,gelatin methacrylate(GelMA),a photocurable protein,has been widely used in 3D bioprinting process owing to its excellent cellular responses,biocompatibility and biodegradability.However,GelMA still shows a low processability due to the severe temperature dependence of viscosity.To overcome this obstacle,we propose a two-stage temperature control system to effectively control the viscosity of GelMA.To optimize the process conditions,we evaluated the temperature of the cooling system(jacket and stage).Using the established system,three GelMA scaffolds were fabricated in which different concentrations(0,3 and 10 wt%)of silanated silica particles were embedded.To evaluate the performances of the prepared scaffolds suitable for hard tissue regeneration,we analyzed the physical(viscoelasticity,surface roughness,compressive modulus and wettability)and biological(human mesenchymal stem cells growth,western blotting and osteogenic differentiation)properties.Consequently,the composite scaffold with greater silica contents(10 wt%)showed enhanced physical and biological performances including mechanical strength,cell initial attachment,cell proliferation and osteogenic differentiation compared with those of the controls.Our results indicate that the GelMA/silanated silica composite scaffold can be potentially used for hard tissue regeneration. | Eunjeong Choi Dongyun Kim Donggu Kang Gi Hoon Yang Bongsu Jung MyungGu Yeo Min-Jeong Park SangHyun An KyoungHo Lee Jun Sik Kim Jong Chul Kim Woonhyeok Jeong Hye Hyun Yoo Hojun Jeon | 2021 | Regenerative Biomaterials2021，8，2： | 2 |

| 16 | Hepatic fat quantification magnetic resonance for monitoring treatment response in pediatric nonalcoholic steatohepatitis显示文摘AIM: To evaluate the possibility of treatment effect monitoring using hepatic fat quantification magnetic resonance(MR) in pediatric nonalcoholic steatohepatitis(NASH).METHODS: We retrospectively reviewed the medical records of patients who received educational recommendations and vitamin E for NASH and underwent hepatic fat quantification MR from 2011 to 2013.Hepatic fat fraction(%) was measured using dual- and triple-echo gradient-recalled-echo sequences at 3T.The compliant and non-compliant groups were compared clinically,biochemically,and radiologically.RESULTS: Twenty seven patients(M:F = 24:3; mean age: 12 ± 2.3 years) were included(compliant group = 22,non-compliant = 5).None of the baseline findings differed between the 2 groups,except for triglyceride level(compliant vs non-compliant,167.7 mg/d L vs 74.2 mg/d L,P = 0.001).In the compliant group,high-density lipoprotein increased and all other parameters decreased after 1-year follow-up.However,there were various changes in the non-compliant group.Dualecho fat fraction(-19.2% vs 4.6,P < 0.001),tripleecho fat fraction(-13.4% vs 3.5,P < 0.001),alanine aminotransferase(-110.7 IU/L vs-10.6 IU/L,P = 0.047),total cholesterol(-18.1 mg/d L vs 3.8 mg/d L,P = 0.016),and triglyceride levels(-61.3 mg/d L vs 11.2 mg/d L,P = 0.013) were significantly decreased only in the compliant group.The change in body mass index and dual-echo fat fraction showed a positive correlation(ρ = 0.418,P = 0.030).CONCLUSION: Hepatic fat quantification MR can be a non-invasive,quantitative and useful tool for monitoring treatment effects in pediatric NASH. | Hong Koh Seung Kim Myung-Joon Kim Hyun Gi Kim Hyun Joo Shin Mi-Jung Lee | 2015 | World Journal of Gastroenterology2015，21，33： | 1 |
