| 2 | Current status of radiofrequency ablation of hepatocellular carcinoma显示文摘Loco-regional treatments for hepatocellular carcinoma(HCC) are important alternatives to curative transplantation or resection.Among them,radiofrequency ablation(RFA) is accepted as the most popular technique showing excellent local tumor control and acceptable morbidity.The current role of RFA is well documented in the evidence-based practice guidelines of European Association of Study of Liver,American Association of Study of the Liver Disease and Japanese academic societies.Several randomized controlled trials have confirmed that RFA is superior to percutaneous ethanol injections in terms of local tumor control and survival.The overall survival after RFA is comparable to after surgical resection in a selected group of patients with smaller(< 3 cm) tumors.Currently,the clinical benefits of combined RFA with transarterial chemoembolization for intermediate stage HCC are increasingly being explored.Here we review the ongoing technical advancements of RFA and future potential. | Hyunchul Rhim Hyo K Lim Dongil Choi | 2010 | World Journal of Gastrointestinal Surgery2010，2，4： | 7 |
| 3 | Concurrent and subsequent radiofrequency ablation combined with hepatectomy for hepatocellular carcinomas显示文摘Partial hepatectomy has long been the standard treatment modality for patients with hepatocellular carcinoma(HCC),although the majority of patients with HCCs are not candidates for curative resection.Radiofrequency ablation(RFA) has been widely used as the preferred locoregional therapy.RFA and hepatectomy can be complementary to each other for the treatment of multifocal HCCs.Combining hepatectomy with RFA permits the removal of larger tumors while simultaneously ablating any smaller residual tumors.By using this combination treatment,more patients might become candidates for curative resection.For treating recurrent tumors involving the liver after hepatectomy,RFA has been performed recently instead of transcatheter arterial chemoembolization or ethanol ablation.Many retrospective studies on the combination of RFA and hepatectomy demonstrate favorable results of effectiveness and safety.However,further investigation of prospective design will be needed to confirm these encouraging results. | Dongil Choi Hyo K Lim Hyunchul Rhim | 2010 | World Journal of Gastrointestinal Surgery2010，2，4： | 6 |
| 4 | Hepatic resection vs percutaneous radiofrequency ablation of hepatocellular carcinoma abutting right diaphragm显示文摘BACKGROUND It is usually difficult to adequately conduct percutaneous ultrasound-guided radiofrequency(RF) ablation for hepatocellular carcinomas(HCCs) abutting the diaphragm. Our hypothesis was that the subphrenic location of HCC could have an effect on the long-term therapeutic outcomes after hepatic resection and RF ablation.AIM To compare the long-term therapeutic outcomes of hepatic resection and percutaneous RF ablation for HCCs abutting the diaphragm.METHODS A total of 143 Child-Pugh class A patients who had undergone hepatic resection(n = 80) or percutaneous ultrasound-guided RF ablation(n = 63) for an HCC(≤ 3 cm) abutting the right diaphragm were included. Cumulative local tumor progression(LTP), cumulative intrahepatic distant recurrence(IDR), disease-free survival(DFS), and overall survival(OS) rates were estimated. Prognostic factors for DFS and OS were analyzed. Complications were evaluated.RESULTS The cumulative IDR rate, DFS rate, and OS rate for the hepatic resection group and RF ablation group at 5 years were '35.9% vs 65.8%', '64.1% vs 18.3%', and'88.4% vs 68.7%', respectively. Hepatic resection was an independent prognostic factor for DFS(P ≤ 0.001; hazard ratio, 0.352; 95%CI: 0.205, 0.605; with RF ablation as the reference category); however, treatment modality was not an independent prognostic factor for OS. The LTP rate was 46.6% at 5 years for the RF ablation group. The major complication rate was not significantly different between the groups(P = 0.630). The rate of occurrence of peritoneal seeding was higher in the RF ablation group(1.3% vs 9.5%, P = 0.044).CONCLUSION Although OS was not significantly different between patients who had gone hepatic resection or percutaneous RF ablation for HCCs abutting the diaphragm,DFS was better in the hepatic resection group. | Kyoung Doo Song Hyo Keun Lim Hyunchul Rhim Min Woo Lee Tae Wook Kang Yong Han Paik Jong Man Kim Jae-Won Joh | 2019 | World Journal of Gastrointestinal Oncology2019，11，3： | 6 |
| 5 | Single hepatocellular carcinoma ≤ 3 cm in left lateral segment:Liver resection or radiofrequency ablation?显示文摘AIM:To evaluate the long-term results of radiofrequency ablation(RFA)compared to left lateral sectionectomy(LLS)in patients with Child-Pugh class A disease for the treatment of single and small hepatocellular carcinoma(HCC)in the left lateral segments.METHODS:We retrospectively reviewed the data of133 patients with single HCC(≤3 cm)in their left lateral segments who underwent curative LLS(n=66)or RFA(n=67)between 2006 and 2010.RESULTS:The median follow-up period was 33.5mo in the LLS group and 29 mo in the RFA group(P=0.060).Most patients had hepatitis B virus-related HCC.The hospital stay was longer in the LLS group than in the RFA group(8 d vs 2 d,P<0.001).The 1-,2-,and 3-year disease-free survival and overall survival rates were 80.0%,68.2%,and 60.0%,and 95.4%,92.3%,and 92.3%,respectively,for the LLS group;and 80.8%,59.9%,and 39.6%,and 98.2%,92.0%,and 74.4%,respectively,for the RFA group.The disease-free survival curve and overall survival curve were higher in the LLS group than in the RFA group(P=0.012 and P=0.013,respectively).Increased PIVKA-Ⅱlevels and small tumor size were associated with HCC recurrence in multivariate analysis.CONCLUSION:Liver resection is suitable for single HCC≤3 cm in the left lateral segments. | Jong Man Kim Tae Wook Kang Choon Hyuck David Kwon Jae-Won Joh Justin Sangwook Ko Jae Berm Park Hyunchul Rhim Joon Hyeok Lee Sung Joo Kim Seung Woon Paik | 2014 | World Journal of Gastroenterology2014，20，14： | 4 |
| 6 | Simultaneous emission of orthogonal handedness in circular polarization from a single luminophore显示文摘The direct emission of circularly polarized(CP)light improves the efficiency of an organic light-emitting diode and characterizes the secondary structure of proteins.In most cases,CP light is generated from a luminescent layer containing chiral characteristics,thereby generating only one kind of CP light in an entire device.Here,we propose direct CP light emissions using a twisted achiral conjugate polymer without any chiral dopant as an emitting layer(EML).The twisted structure is induced in the mesogenic conjugate polymer due to its elasticity by applying different alignment directions to its upper and lower interfaces.Furthermore,we demonstrate the simultaneous emission of orthogonal CP light in a single luminescent device by patterning different alignment directions on the surfaces of the EML.The light source with multipolarization including the orthogonal CP states is applicable to many applications in biosensors and optical devices. | Kyungmin Baek Dong-Myung Lee Yu-Jin Lee Hyunchul Choi Jeongdae Seo Inbyeong Kang Chang-Jae Yu Jae-Hoon Kim | 2019 | Light(Science & Applications)2019，8，1： | 3 |
| 7 | Dynamic Response of Mold Oscillator Interacting with Steel Slabs显示文摘A mathematical model to show the dynamic response of the mold oscillator was suggested.The model considered a frictional interaction between the mold oscillator and slab as several connected nodes.The governing equation considered the slab as a multi-degree-of-freedom(DoF)system,and included a hysteresis model to describe elastic-plastic behavior of the slab;the mold oscillator was given two DoF by utilizing pressure and displacement experiment data.Simulations indicate that the mold and slab execute various vibrations,and that mold oscillation marks are caused by a stick-and-slip phenomenon during intervals,in which the slab contacting the mold moves downward compared to the other slab(negative strip time).The slab shows the formation of mold oscillation marks to previous formation criterion equally when the mold velocity is faster than the casting speed about downward.The oscillation mark will grow up over 2 Hz exciting frequency with constant 4 mm stroke in simulations.Finally,the negative strip time was compared to the frictional force,hysteresis variable,and plastic force to investigate formation mechanism of the oscillation marks. | Yonghui PARK Hyunchul PARK | 2016 | Journal of Iron and Steel Research(International)2016，23，9： | 2 |

| 9 | Axial strain enhances osteotomy repair with a concomitant increase in connexin43 expression显示文摘The mechanical environment is known to influence fracture healing. We speculated that connexin43(Cx43) gap junctions, which impact skeletal homeostasis, fracture healing and the osteogenic response to mechanical load,may play a role in mediating the response of the healing bone to mechanical strain. Here, we used an established rat fracture model, which uses a 2 mm osteotomy gap stabilized by an external fixator, to examine the impact of various cyclical axial loading protocols(2%, 10%, and 30% strain) on osteotomy healing. We examined the presence of Cx43 in the osteotomy-healing environment and assessed how mechanical strain modulates Cx43 expression patterns in the callus. We demonstrated that increased cyclical axial strain results in increased radiographic and histologic bone formation. In addition, we show by immunohistochemistry that Cx43 is abundantly expressed in the healing callus, with the expression most robust in samples exposed to increased cyclical axial strain. These data are consistent with the concept that an increase in Cx43 expression by mechanical load may be part of the mechanisms by which mechanical forces enhances fracture healing. | Rishi R Gupta Hyunchul Kim Yu-Kwan Chan Carla Hebert Leah Gitajn David J Yoo Robert V O’Toole Adam H Hsieh Joseph P Stains | 2015 | Bone Research2015，3，2： | 2 |
