| 1 | Increased intestinal macromolecular permeability and urine nitrite excretion associated with liver cirrhosis with ascites显示文摘AIM: To determine intestinal permeability,the serum tumor necrosis factor (TNF)-α level and urine nitric oxide (NO) metabolites are altered in liver cirrhosis (LC) with or without ascites. METHODS: Fifty-three patients with LC and 26 healthy control subjects were enrolled in the study. The intestinal permeability value is expressed as the percentage of polyethylene glycol (PEG) 400 and 3350 retrieval in 8-h urine samples as determined by high performance liquid chromatography. Serum TNF-α concentrations and urine NO metabolites were determined using an enzyme-linked immunosorbent assay (ELISA) and Greiss reaction method,respectively. RESULTS: The intestinal permeability index wassignif icantly higher in patients with LC with ascites than in healthy control subjects or patients with LC without ascites (0.88 ± 0.12 vs 0.52 ± 0.05 or 0.53 ± 0.03,P < 0.05) and correlated with urine nitrite excretion (r = 0.98). Interestingly,the serum TNF-α concentra-tion was significantly higher in LC without ascites than in control subjects or in LC with ascites (198.9 ± 55.8 pg/mL vs 40.9 ± 12.3 pg/mL or 32.1 ± 13.3 pg/mL,P < 0.05). Urine nitrite excretion was significantly higher in LC with ascites than in the control subjects or in LC without ascites (1170.9 ± 28.7 μmol/L vs 903.1 ± 55.1 μmol/L or 956.7 ± 47.7 μmol/L,P < 0.05). CONCLUSION: Increased intestinal macromolecular permeability and NO is probably of importance in the pathophysiology and progression of LC with ascites,but the serum TNF-α concentration was not related to LC with ascites. | Soong Lee Seung-Cheol Son Moon-Jong Han Woo-Jin Kim Soo-Hyun Kim Hye-Ran Kim Woo-Kyu Jeon Ki-Hong Park Myung-Geun Shin | 2008 | World Journal of Gastroenterology2008，14，24： | 16 |
| 2 | Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite. | Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon | 2009 | World Journal of Gastroenterology2009，15，1： | 15 |
| 3 | 术前肌电图和脑干听觉诱发电位与面肌痉挛微血管减压术后迟发性面瘫发生的关系(英文)显示文摘Background Delayed facial palsy ( DFP) after microvascular decompression ( MVD) in patients with hemifacial spasm ( HFS) is not uncommon,but the cause remains unknown. Objectives To assess whether intraoperative electromyography ( EMG) and brainstem auditory evoked potential ( BAEP) can predict DFP after MVD. Methods Between September 2009 and February 2011 we examined 86 patients,9 of whom ( 10. 4% ) developed DFP after MVD on the same side. All patients underwent MVD and were followed - up for a median period of 13 months ( range 6-22) . We retrospectively examined intraoperative facial EMG and BAEP findings using our MVD patients' registry. We excluded secondary HFS and immediate postoperative facial palsy after MVD in this study. We assessed the prevalence and clinical characteristics of DFP and compared EMG and BAEP findings between DFP and non-DFP groups. Results: All pa- tients recovered completely,with a mean time to recovery of 37. 8 days ( range 22-57) . There were no significant differences between DFP and non - DFP patients in terms of the amplitude and latency of intraoperative EMG and BAEP. Conclusion The usefulness of intraoperative facial EMG and BAEP is limited and cannot predict DFP after MVD for HFS. We speculate that DFP after MVD is not associated with permanent nerve damage according to the EMG findings. | Kim HJ Park YS Ryu JS Huh R Han I Shin DA Kim TG Cho KG Chung SS | 2012 | 中华神经外科疾病研究杂志2012，11，4： | 13 |

| 5 | Risk prediction platform for pancreatic fistula after pancreatoduodenectomy using artificial intelligence显示文摘BACKGROUND Despite advancements in operative technique and improvements in postoperative managements,postoperative pancreatic fistula(POPF)is a life-threatening complication following pancreatoduodenectomy(PD).There are some reports to predict POPF preoperatively or intraoperatively,but the accuracy of those is questionable.Artificial intelligence(AI)technology is being actively used in the medical field,but few studies have reported applying it to outcomes after PD.AIM To develop a risk prediction platform for POPF using an AI model.METHODS Medical records were reviewed from 1769 patients at Samsung Medical Center who underwent PD from 2007 to 2016.A total of 38 variables were inserted into AI-driven algorithms.The algorithms tested to make the risk prediction platform were random forest(RF)and a neural network(NN)with or without recursive feature elimination(RFE).The median imputation method was used for missing values.The area under the curve(AUC)was calculated to examine the discriminative power of algorithm for POPF prediction.RESULTS The number of POPFs was 221(12.5%)according to the International Study Group of Pancreatic Fistula definition 2016.After median imputation,AUCs using 38 variables were 0.68±0.02 with RF and 0.71±0.02 with NN.The maximal AUC using NN with RFE was 0.74.Sixteen risk factors for POPF were identified by AI algorithm:Pancreatic duct diameter,body mass index,preoperative serum albumin,lipase level,amount of intraoperative fluid infusion,age,platelet count,extrapancreatic location of tumor,combined venous resection,co-existing pancreatitis,neoadjuvant radiotherapy,American Society of Anesthesiologists’score,sex,soft texture of the pancreas,underlying heart disease,and preoperative endoscopic biliary decompression.We developed a web-based POPF prediction platform,and this application is freely available at http://gffzz52cab37b8d4e4d2chckbow55x6pp56ubp.ffgz.tsg.suse.edu.cn This study is the first to predict POPF with multiple risk factors using AI.This platform is reliable(AUC 0.74),so it could be used to select patients who need especially intense therapy and to preoperatively establish an effective treatment strategy. | In Woong Han Kyeongwon Cho Youngju Ryu Sang Hyun Shin Jin Seok Heo Dong Wook Choi Myung Jin Chung Oh Chul Kwon Baek Hwan Cho | 2020 | World Journal of Gastroenterology2020，26，30： | 12 |
| 6 | Effect of metronome rates on the quality of bag-mask ventilation during metronome-guided 30:2 cardiopulmonary resuscitation:A randomized simulation study显示文摘BACKGROUND: Metronome guidance is a feasible and effective feedback technique to improve the quality of cardiopulmonary resuscitation(CPR). The rate of the metronome should be set between 100 to 120 ticks/minute and the speed of ventilation may have crucial effect on the quality of ventilation. We compared three different metronome rates(100, 110, 120 ticks/minute) to investigate its effect on the quality of ventilation during metronome-guided 30:2 CPR.METHODS: This is a prospective, randomized, crossover observational study using a Respi Trainer r. To simulate 30 chest compressions, one investigator counted from 1 to 30 in cadence with the metronome rate(1 count for every 1 tick), and the participant performed 2 consecutive ventilations immediately following the counting of 30. Thirty physicians performed 5 sets of 2 consecutive(total 10) bag-mask ventilations for each metronome rate. Participants were instructed to squeeze the bag over 2 ticks(1.0 to 1.2 seconds depending on the rate of metronome) and defl ate the bag over 2 ticks. The sequence of three different metronome rates was randomized.RESULTS: Mean tidal volume significantly decreased as the metronome rate was increased from 110 ticks/minute to 120 ticks/minute(343±84 m L vs. 294±90 m L, P=0.004). Peak airway pressure significantly increased as metronome rate increased from 100 ticks/minute to 110 ticks/minute(18.7 vs. 21.6 mm Hg, P=0.006).CONCLUSION: In metronome-guided 30:2 CPR, a higher metronome rate may adversely affect the quality of bag-mask ventilations. In cases of cardiac arrest where adequate ventilation support is necessary, 100 ticks/minute may be better than 110 or 120 ticks/minute to deliver adequate tidal volume during audio tone guided 30:2 CPR. | Ji Ung Na Sang Kuk Han Pil Cho Choi Dong Hyuk Shin | 2017 | World Journal of Emergency Medicine2017，8，2： | 12 |

| 8 | Clinical usefulness of ankle brachial index and brachial-ankle pulse wave velocity in patients with ischemic stroke显示文摘Ankle brachial index(ABI) and brachial-ankle pulse wave velocity(baPWV) are widely used noninvasive modalities to evaluate atherosclerosis.Recently,evidence has increased supporting the use of ABI and baPWV as markers of cerebrovascular disease.This study sought to examine the relationship between ABI and baPWV with ischemic stroke.This study also aimed to determine which pathogenic mechanism,large artery disease(LAD) or small vessel disease(SVD),is related to ABI or baPWV.Retrospectively,121 patients with ischemic stroke and 38 subjects with no obvious ischemic stroke history were recruited.First,ABI and baPWV were compared between the groups.Then,within the stroke group,the relevance of ABI and baPWV with regard to SVD and LAD,which were classified by brain magnetic resonance image(MRI) and magnetic resonance angiography(MRA) or computed tomography angiography(CTA) findings,was assessed.The baPWV was higher in the stroke group than non-stroke group(1,944.18±416.6 cm/s vs.1,749.76±669.6 cm/s,P< 0.01).Regarding LAD,we found that mean ABI value was lower in the group with extracranial large artery stenosis(P< 0.01),and there was an inverse linear correlation between ABI and the grade of extracranial large artery stenosis(P<0.01).For SVD,there was a significant correlation between SVD and baPWV(2,057.6±456.57 cm/s in the SVD(+) group vs.1,491 ±271.62 cm/s in the SVD(-) group;P < 0.01).However,the grade of abnormalities detected in SVD did not correlate linearly with baPWV.These findings show that baPWV is a reliable surrogate marker of ischemic stroke.Furthermore,baPWVand ABI can be used to indicate the presence of small vessel disease and large arterial disease,respectively. | Hyung-Suk Lee Hye Lim Lee Ho-seong Han Minju Yeo Ji Seon Kim Sung-Hyun Lee Sang-Soo Lee Dong-Ick Shin | 2016 | The Journal of Biomedical Research2016，30，4： | 8 |
| 9 | Liver intravoxel incoherent motion diffusion-weighted imaging for the assessment of hepatic steatosis and fibrosis in children显示文摘AIM To evaluate the correlation between intravoxel incoherent motion(IVIM) diffusion-weighted imaging(DWI) parameters and the degree of hepatic steatosis and fibrosis in children.METHODS This retrospective study was approved by the institutional review board. The children(≤ 18 years) who underwent liver IVIM DWI with 8 b-values under the suspicion of hepatic steatosis or fibrosis from February 2013 to November 2016 were included. Subjects were divided into normal, fatty liver(FAT), and fibrotic liver(FIB) groups. The slow diffusion coefficient(D), fast diffusion coefficient(D*), perfusion fraction(f), and apparent diffusion coefficient(ADC) were measured. MR proton density fat fraction(PDFF), MR elastography(MRE), and IVIM values were compared.RESULTS A total of 123 children(median age of 12 years old, range: 6-18 years) were included, with 8 in the normal group, 93 in the FAT group, and 22 in the FIB group. The D* values were lower in the FIB group compared with those of the normal(P = 0.015) and FAT(P = 0.003) groups. The f values were lower in the FIB group compared with the FAT group(P = 0.001). In multivariate analyses, PDFF value was positively correlated with f value(β = 3.194, P < 0.001), and MRE value was negatively correlated with D* value(β =-7.031, P = 0.032). The D and ADC values were not influenced by PDFF or MRE value.CONCLUSION In liver IVIM DWI with multiple b-values in children, there was a positive correlation between hepatic fat and blood volume, and a negative correlation between hepatic stiffness and endovascular blood flow velocity, while diffusion-related parameters were not affected. | Hyun Joo Shin Haesung Yoon Myung-Joon Kim Seok Joo Han Hong Koh Seung Kim Mi-Jung Lee | 2018 | World Journal of Gastroenterology2018，24，27： | 8 |
| 10 | Redefining Budd-Chiari syndrome:A systematic review显示文摘AIM:To re-examine whether hepatic vein thrombosis(HVT)(classical Budd-Chiari syndrome)and hepatic vena cava-Budd Chiari syndrome(HVC-BCS)are the same disorder.METHODS:A systematic review of observational studies conducted in adult subjects with primary BCS,hepatic vein outflow tract obstruction,membranous obstruction of the inferior vena cava(IVC),obliterative hepatocavopathy,or HVT during the period of January2000 until February 2015 was conducted using the following databases:Cochrane Library,CINAHL,MEDLINE,Pub Med and Scopus.RESULTS:Of 1299 articles identified,26 were included in this study.Classical BCS is more common in women with a pure hepatic vein obstruction(49%-74%).HVCBCS is more common in men with the obstruction often located in both the inferior vena cava and hepatic veins(14%-84%).Classical BCS presents with acute abdominal pain,ascites,and hepatomegaly.HVC-BCS presents with chronic abdominal pain and abdominalwall varices.Myeloproliferative neoplasms(MPN)are the most common etiology of classical BCS(16%-62%)with the JAK2V617-F mutation found in 26%-52%.In HVCBCS,MPN are found in 4%-5%,and the JAK2V617-F mutation in 2%-5%.Classical BCS responds well to medical management alone and 1st line management of HVC-BCS involves percutaneous recanalization,with few managed with medical management alone.CONCLUSION:Systematic review of recent data suggests that classical BCS and HVC-BCS may be two clinically different disorders that involve the disruption of hepatic venous outflow. | Naomi Shin Young H Kim Hao Xu Hai-Bin Shi Qing-Qiao Zhang Jean Paul Colon Pons Ducksoo Kim Yi Xu Fei-Yun Wu Samuel Han Byung-Boong Lee Lin-Sun Li | 2016 | World Journal of Hepatology2016，8，16： | 6 |
| 11 | 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 |
| 12 | Laser dissimilar welding of CoCrFeMnNi-high entropy alloy and duplex stainless steel显示文摘High entropy alloys(HEAs)have superior mechanical properties that have enabled them to be used as structural materials in nuclear and aerospace applications.As a dissimilar joint design is required for these applications,we created a dissimilar joint between CoCrFeMnNi-HEA and duplex stainless steel(DSS)through laser beam welding;a technique capable of producing a sound joint between the two materials.Micro structure examination using SEM/EBSD/XRD analysis revealed that the weld metal(WM)exhibits an FCC phase regardless of the postweld heat treatment(PWHT)temperature(800 and 1000℃)without forming detrimental intermetallic compounds or microsegregation.The heat-affected zone of the CoCrFeMnNi-HEA showed CrMn oxide inclusions while that of the DSS showed no inclusions.Moreover,a lower hardness was recorded by the WM compared to the base metal after welding.After PWHT,the hardness of the WM,CoCrFeMnNi-HEA,and DSS decreased with an increase in the PWHT temperature.However,the decrease in the hardness of the HEA was more significant than in the WM and DSS.The cause for this reduction in hardness was attributed to recrystallization and grain growth.In addition,a strength of 584 MPa with low ductility was recorded after welding.The obtained strength was lower than that of the BMs,but comparable to that of the welded CoCrFeMnNi-HEA.The application of PWHT resulted in over a 20%increment in ductility,with only a marginal reduction in strength.The defo rmation mechanism in the as-weld joint was mainly dominated by dislocation while that for the PWHT joint was twinning.We propose laser beam offset welding as a technique to improve the mechanical properties of the dissimilar joint,which will be the subject of future studies. | Nana Kwabena Adomako Giseung Shin Nokeun Park Kyoungtae Park Jeoung Han Kim | 2021 | Journal of Materials Science & Technology2021，，26： | 6 |
| 13 | An herbal formula,CGX,exerts hepatotherapeutic effects on dimethylnitrosamine-induced chronic liver injury model in rats显示文摘AIM: To evaluate the therapeutic effect of Chunggan extract (CGX), a modified traditional Chinese hepatotherapeutic herbal, on the dimethylnitrosamine (DMN)-induced chronic liver injury model in rats. METHODS: Liver injuries were induced in Wistar rats by injection of DMN (ip, 10 mg/mL per kg) for 3 consecutive days per week for 4 wk. The rats were administered with CGX (po, 100 or 200 mg/kg per day) or distilled water as a control daily for 4 wk starting from the 15th d of the DMN treatment. Biochemical parameters (serum albumin, bilirubin, ALP, AST and ALT), lipid peroxides, hydroxyproline, as well as histological changes in liver tissues were analyzed. In addition, gene expression of TNF-α, TGF-b, TIMP-1, TIMP-2, PDGF-b, and MMP-2, all of which are known to be associated with liver fibrosis, were analyzed using real-time PCR. RESULTS: CGX administration restored the spleen weight to normal after having been increased by DMN treatment. Biochemical analysis of the serum demonstrated that CGX significantly decreased the serum level of ALP (P < 0.05), ALT (P < 0.01), and AST (P < 0.01) that had been elevated by DMN treatment. CGX administration moderately lowered lipid peroxide production and markedly lowered hydroxyproline generation caused by DMN treatment in accordance with histopathological examination. DMN treatment induced a highly up-regulated expression of TNF-α, TGF-b, TIMP-1, TIMP-2, PDGF-b, and MMP-2. Of these, the gene expression encoding PDGF-b and MMP-2 was still further enhanced 2 wk after secession of the 4-wk DMN treatment, and was remarkably ameliorated by CGX administration. CONCLUSION: CGX exhibits hepatotherapeutic proper- ties against chronic hepatocellular destruction and consequential liver fibrosis. | Jang-Woo Shin Jin-Young Son Se-Mi Oh Seung-Hyun Han Jing-Hua Wang Jung-Hyo Cho Chong-Kwan Cho Hwa-Seung Yoo Yeon-Weol Lee Myong-Min Lee Xiao Ping Hu Chang-Gue Son | 2006 | World Journal of Gastroenterology2006，12，38： | 5 |
| 14 | Predicting gastroesophageal varices through spleen magnetic resonance elastography in pediatric liver fibrosis显示文摘BACKGROUND A recent retrospective study confirmed that hepatic stiffness and splenic stiffness measured with magnetic resonance elastography(MRE) are strongly associated with the presence of esophageal varices. In addition, strong correlations have been reported between splenic stiffness values measured with MRE and hepatic venous pressure gradients in animal models. However, most studies have been conducted on adult populations, and previous pediatric MRE studies have only demonstrated the feasibility of MRE in pediatric populations, while the actual clinical application of spleen MRE has been limited.AIM To assess the utility of splenic stiffness measurements by MRE to predict gastroesophageal varices in children.METHODS We retrospectively reviewed abdominal MRE images taken on a 3 T system in pediatric patients. Patients who had undergone Kasai operations for biliary atresia were selected for the Kasai group, and patients with normal livers and spleens were selected for the control group. Two-dimensional spin-echo echoplanar MRE acquisition centered on the liver, with a pneumatic driver at 60 Hz and a low amplitude, was performed to obtain hepatic and splenic stiffness values. Laboratory results for aspartate aminotransferase to platelet ratio index(APRI) were evaluated within six months of MRE, and the normalized spleen size ratio was determined with the upper normal size limit. All Kasai group patients underwent gastroesophageal endoscopy during routine follow-up. The MannWhitney U test, Kendall's tau b correlation and diagnostic performance analysis using the area under the curve(AUC) were performed for statistical analysis.RESULTS The median spleen MRE value was 5.5 kPa in the control group(n = 9, age 9-18 years, range 4.7-6.4 kPa) and 8.6 kPa in the Kasai group(n = 22, age 4-18 years,range 5.0-17.8 kPa). In the Kasai group, the APRI, spleen size ratio and spleen MRE values were higher in patients with portal hypertension(n = 11) than in patients without(n = 11)(all P < 0.001) and in patients with gastroesophageal varices(n = 6) than in patients without(n = 16)(all P < 0.05), even though their liver MRE values were not different. The APRI(τ = 0.477, P = 0.007), spleen size ratio(τ = 0.401, P = 0.024) and spleen MRE values(τ = 0.426, P = 0.016) also correlated with varices grades. The AUC in predicting gastroesophageal varices was 0.844 at a cut-off of 0.65(100% sensitivity and 75% specificity) for the APRI,and 0.844 at a cut-off of 9.9 kPa(83.3% sensitivity and 81.3% specificity) for spleen MRE values.CONCLUSION At a cut-off of 9.9 kPa, spleen MRE values predicted gastroesophageal varices as well as the APRI and spleen size ratio in biliary atresia patients after the Kasai operation. However, liver MRE values were not useful for this purpose. | Haesung Yoon Hyun Joo Shin Myung-Joon Kim Seok Joo Han Hong Koh Seung Kim Mi-Jung Lee | 2019 | World Journal of Gastroenterology2019，25，3： | 5 |

| 16 | Digital Vision Based Concrete Compressive Strength Evaluating Model Using Deep Convolutional Neural Network显示文摘Compressive strength of concrete is a significant factor to assess building structure health and safety.Therefore,various methods have been developed to evaluate the compressive strength of concrete structures.However,previous methods have several challenges in costly,time-consuming,and unsafety.To address these drawbacks,this paper proposed a digital vision based concrete compressive strength evaluating model using deep convolutional neural network(DCNN).The proposed model presented an alternative approach to evaluating the concrete strength and contributed to improving efficiency and accuracy.The model was developed with 4,000 digital images and 61,996 images extracted from video recordings collected from concrete samples.The experimental results indicated a root mean square error(RMSE)value of 3.56(MPa),demonstrating a strong feasibility that the proposed model can be utilized to predict the concrete strength with digital images of their surfaces and advantages to overcome the previous limitations.This experiment contributed to provide the basis that could be extended to future research with image analysis technique and artificial neural network in the diagnosis of concrete building structures. | Hyun Kyu Shin Yong Han Ahn Sang Hyo Lee Ha Young Kim | 2019 | Computers, Materials & Continua2019，，9： | 5 |
| 17 | Stereotactic body radiotherapy for isolated paraaortic lymph node recurrence from colorectal cancer显示文摘AIM:To evaluate the efficacy and complications of stereotactic body radiotherapy in localized paraaortic lymph node recurrence from colorectal cancer.METHODS:From 2003 to 2009,7 patients with paraaortic lymph node recurrence(1-3 lesions)from colorectal cancer were treated with stereotactic body radiotherapy.Total gross tumor volumes ranged from 4 to 40 mL.The doses were escalated from 36 Gy/patient to 51 Gy/patient and were delivered in 3 fractions.RESULTS:One and 3 year overall survival rates were 100%and 71.4%,respectively,and median survival was 37 mo.GradeⅣintestinal obstruction was reported in 1 of 7 patients.This patient received 48 Gy in 3 fractions with a maximum point dose to the intestine of 53 Gy and V45Gy=3.6 mL.However,6 patients received an intestinal maximum point dose of<51 Gy and V45Gy of<1 mL,and did not develop any severe complications.CONCLUSION:This pilot study suggests selected paraaortic lymph node recurrence(1-3 closed lesions) that failed to respond to chemotherapy can be potentially salvaged by stereotactic body radiotherapy. | Mi-Sook Kim Chul Koo Cho Kwang Mo Yang Dong Han Lee Sun Mi Moon Young Joo Shin | 2009 | World Journal of Gastroenterology2009，15，48： | 4 |

| 19 | Differential diagnoses of magnetic resonance imaging for suspected acute appendicitis in pregnant patients显示文摘BACKGROUND: Accurate and timely diagnosis of acute surgical disease in pregnant patient is chal enging. Although magnetic resonance imaging(MRI) is the most accurate modality to diagnose acute appendicitis in pregnant patients, it is often used as a last resort because of high cost and long scan time. We performed this study to analyze differential diagnoses of appendix MRI and to investigate if there are any blood tests that can predict surgical condition in pregnant patients.METHODS: A retrospective, cross-sectional study was conducted on 46 pregnant patients who underwent non-enhanced appendix MRI in suspicion of acute appendicitis from 2010 to 2016. Differential diagnoses of appendix MRI were analyzed and blood tests were compared between those who had surgical and non-surgical disease.RESULTS: Appendix MRI differentiated two surgical disease; acute appendicitis and ovarian torsion; and various non-surgical conditions such as uterine myoma, hydronephrosis, ureterolithiasis and diverticulitis among clinically suspected acute appendicitis in pregnancy. The diagnostic accuracy of MRI for acute appendicitis in this study was 93.5%. Patients who had surgical disease showed significantly higher WBC count(≥11,000/mm^3), proportion of neutrophils in the WBC(≥79.9%), neutrophil-to-lymphocyte ratio(NLR≥6.4), levels of C-reactive protein(CRP≥1.82 mg/dL) and bilirubin(≥0.66 mg/dL) than those who had non-surgical disease.CONCLUSION: MRI can reliably differentiate surgical conditions and several blood tests(WBC, proportion of neutrophils in the WBC, NLR, CRP, bilirubin) can help anticipate acute surgical condition among pregnant patients suspected to have acute appendicitis. | Ji Yong Jung Ji Ung Na Sang Kuk Han Pil Cho Choi Jang Hee LEE Dong Hyuk Shin | 2018 | World Journal of Emergency Medicine2018，9，1： | 4 |
