| 1 | Radiotherapy as valid modality for hepatocellular carcinoma with portal vein tumor thrombosis显示文摘Although the current standard treatment for hepatocellular carcinoma(HCC) with portal vein tumor thrombosis(PVTT) is sorafenib, many previous studies have established the need for a reliable local modality for PVTT control, which is a major cause of liver function deterioration and metastasis. Additionally, there is growing evidence for the prognostic significance of PVTT classification according to the location of tumor thrombosis. Favorable outcomes can be obtained by applying local modalities, including surgery or transarterial chemoembolization, especially in second-order or distal branch PVTT. Rapid control of PVTT could maintain or improve liver function and reduce intrahepatic as well as distant metastasis. Radiotherapy(RT) is one of the main locoregional treatment modalities in oncologic fields, but has rarely been used in HCC because of concerns regarding hepatic toxicity. However, with the development of advanced techniques, RT has been increasingly applied in HCC management. Randomized studies have yet to definitively prove the benefit of RT, but several comparative studies have justified the application of RT in HCC. The value of RT is especially noticeable in HCC with PVTT; several prospective and retrospective studies have reported favorable outcomes, including a 40% to 60% objective response rate and median overall survival of 15 mo to 20 mo in responders. In this review, we evaluate the role of RT as an alternative local modality in HCC with PVTT. | Jeong Il Yu Hee Chul Park | 2016 | World Journal of Gastroenterology2016，22，30： | 20 |
| 2 | 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 |
| 3 | 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 |
| 4 | Proton therapy for hepatocellular carcinoma:Current knowledges and future perspectives显示文摘Hepatocellular carcinoma(HCC) is the second leading cause of cancer-related death, as few patients can be treated with currently available curative local modalities. In patients with HCC where curative modalities are not feasible, radiation therapy(RT) has emerged as an alternative or combination therapy. With the development of various technologies, RT has been increasingly used for the management of HCC. Among these advances, proton beam therapy(PBT) has several unique physical properties that give it a finite range in a distal direction, and thus no exit dose along the beam path. Therefore, PBT has dosimetric advantages compared with X-ray therapy for the treatment of HCC. Indeed, various reports in the literature have described the favorable clinical outcomes and improved safety of PBT for HCC patients compared with X-ray therapy. However, there are some technical issues regarding the use of PBT in HCC, including uncertainty of organ motion and inaccuracy during calculation of tissue density and beam range, all of which may reduce the robustness of a PBT treatment plan. In this review, we discuss the physical properties, current clinical data, technical issues, and future perspectives on PBT for the treatment of HCC. | Gyu Sang Yoo Jeong Il Yu Hee Chul Park | 2018 | World Journal of Gastroenterology2018，24，28： | 8 |
| 5 | 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 | Flash‑Induced High‑Throughput Porous Graphene via Synergistic Photo‑Effects for Electromagnetic Interference Shielding显示文摘Porous 2D materials with high conductivity and large surface area have been proposed for potential electromagnetic interference(EMI)shielding materials in future mobility and wearable applications to prevent signal noise,transmission inaccuracy,system malfunction,and health hazards.Here,we report on the synthesis of lightweight and flexible flash-induced porous graphene(FPG)with excellent EMI shielding performance.The broad spectrum of pulsed flashlight induces photo-chemical and photo-thermal reactions in polyimide films,forming 5×10 cm^(2)-size porous graphene with a hollow pillar structure in a few milliseconds.The resulting material demonstrated low density(0.0354 g cm^(−3))and outstanding absolute EMI shielding effectiveness of 1.12×10^(5) dB cm^(2) g^(−1).The FPG was characterized via thorough material analyses,and its mechanical durability and flexibility were confirmed by a bending cycle test.Finally,the FPG was utilized in drone and wearable applications,showing effective EMI shielding performance for internal/external EMI in a drone radar system and reducing the specific absorption rate in the human body. | Jin Soo Lee Jeong‑Wook Kim Jae Hee Lee Yong Koo Son Young Bin Kim Kyoohee Woo Chanhee Lee Il‑Doo Kim Jae Young Seok Jong Won Yu Jung Hwan Park Keon Jae Lee | 2023 | Nano-Micro Letters2023，15，11： | 1 |
