| 2 | Role of surgical resection for multiple hepatocellular carcinomas显示文摘AIM:To clarify the role of surgical resection for multiple hepatocellular carcinomas(HCCs)compared to transarterial chemoembolization(TACE)and liver transplantation(LT). METHODS:Among the HCC patients who were managed at Yonsei University Health System between January 2003 and December 2008,160 patients who met the following criteria were retrospectively enrolled:(1) two or three radiologically diagnosed HCCs;(2)no radiologic vascular invasion;(3)Child-Pugh class A;(4) main tumor smaller than 5 cm in diameter;and(5) platelet count greater than 50 000/mm3.Long-term outcomes were compared among the following three treatment modalities:surgical resection or combined radiofrequency ablation(RFA)(n=36),TACE(n=107), and LT(n=17).The survival curves were computed using the Kaplan-Meier method and compared with a log-rank test.To identify the patients who gained a survival benefit from surgical resection,we also investigated prognostic factors for survival following surgical resection.Multivariate analyses of the prognostic factors for survival were performed using the Cox proportional hazard model. RESULTS:The overall survival(OS)rate was significantly higher in the surgical resection group than in the TACE group(48.1%vs 28.9%at 5 years,P<0.005). LT had the best OS rate,which was better than that of the surgical resection group,although the difference was not statistically significant(80.2%vs 48.1%at 5 years,P=0.447).The disease-free survival rates were also significantly higher in the LT group than in the surgical resection group(88.2%vs 11.2%at 5 years, P<0.001).Liver cirrhosis was the only significant prognostic factor for poor OS after surgical resection. Clinical liver cirrhosis rates were 55.6%(20/36)in the resection group and 93.5%(100/107)in the TACE group.There were 19 major and 17 minor resections. En bloc resection was performed in 23 patients,multisite resection was performed in 5 patients,and combined resection with RFA was performed in 8 patients. In the TACE group,only 34 patients(31.8%)were recorded as having complete remission after primary TACE.Seventy-two patients(67.3%)were retreated with repeated TACE combined with other therapies. In patients who underwent surgical resection,the 16 patients who did not have cirrhosis had higher 5-year OS and disease-free survival rates than the 20 patients who had cirrhosis(80.8%vs 25.5%5-year OS rate, P=0.006;22.2%vs 0%5-year disease-free survival rate,P=0.048).Surgical resection in the 20 patients who had cirrhosis did not provide any survival benefit when compared with TACE(25.5%vs 24.7%5-year OS rate,P=0.225).Twenty-nine of the 36 patients who underwent surgical resection experienced recur-rence.Of the patients with cirrhosis,80%(16/20) were within the Milan criteria at the time of recurrence CONCLUSION:Among patients with two or three HCCs, no radiologic vascular invasion,and tumor diameters≤ 5 cm,surgical resection is recommended only in those without cirrhosis. | Sung Hoon Choi Gi Hong Choi Seung Up Kim Jun Yong Park Dong Jin Joo Man Ki Ju Myoung Soo Kim Jin Sub Choi Kwang Hyub Han Soon Il Kim | 2013 | World Journal of Gastroenterology2013，19，3： | 12 |

| 5 | Sequential transcatheter arterial chemoembolization and portal vein embolization before right hemihepatectomy in patients with hepatocellular carcinoma显示文摘Background:Recent studies showed that sequential selective transcatheter arterial chemoembolization(TACE)and portal vein embolization(PVE)provided better future liver remnant(FLR)regeneration rate and disease-free survival following surgery compared with PVE alone.The present study aimed to clarify whether preoperative sequential TACE and PVE before right hemihepatectomy can reduce postoperative hepatocellular carcinoma(HCC)recurrence and improve long-term disease-free and overall survival.Methods:Recurrence and survival outcomes were retrospectively evaluated in 205 patients with HCC who underwent right hemihepatectomy by a single surgeon from November 1993 to November 2017.Patients were divided into four groups according to the procedure performed before the surgery:sequential TACE and PVE(TACE-PVE),PVE-only,TACE-only,or na?ve control groups.The baseline patient and tumor characteristics,postoperative outcomes,recurrence-free survival and overall survival were analyzed.Results:Baseline patient and tumor characteristics upon diagnosis were similar in all four groups,while sequential TACE and PVE were well tolerated.The TACE-PVE group had a higher mean increase in percentage FLR volume compared with that of the PVE-only group(17.46%±6.63%vs.12.14%±5.93%;P=0.001).The TACE-PVE group had significantly better overall and disease-free survival rates compared with the other groups(both P<0.001).Conclusions:Sequential TACE and PVE prior to surgery can be an effective therapeutic strategy for patients with HCC scheduled for major hepatic resection.The active application of preoperative sequential TACE and PVE for HCC would allow more patients with marginal FLR volume to become candidates for major hepatic resection by promoting compensatory FLR hypertrophy without the deterioration of basal hepatic functional reserve or tumor progression. | Gil Chun Park Sung Gyu Lee Young In Yoon Kyu Bo Sung Gi Young Ko Dong Il Gwon Dong Hwan Jung Yong Kyu Jung | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，3： | 9 |
| 6 | Impact of KRAS mutation and PTEN expression on cetuximab-treated colorectal cancer显示文摘AIM:To investigate the prognostic value of KRAS mutation,and phosphatase and tensin (PTEN) expression in Chinese metastatic colorectal cancer metastatic colorectal cancer (mCRC) patients treated with cetuximab.METHODS:Ninety Chinese mCRC patients treated with cetuximab were evaluated for KRAS mutation and PTEN protein expression by DNA sequencing of codons 12 and 13 and immunohistochemistry,respectively.We then selected 61 patients treated with cetuximab,either in combination with chemotherapy,or alone as a second-line or third-line regimen to assess whether KRAS mutation or PTEN protein expression is associated with the response and the survival time of mCRC patients treated with cetuximab.RESULTS:KRAS mutation was found in 30 (33.3%) tumor samples from the 90 patients,and positive PTEN expression was detected in 58 (64.4%) of the 90 patients.Among the 61 patients who were treated with cetuximab as a second-line or third-line regimen,the resistance to cetuximab was found in 22 patients with KRAS mutation and in 39 patients without KRAS mutation,with a response rate of 4.5% and 46.1% respectively (P=0.001),a shorter median progression-free survival (PFS) time of 14 ± 1.3 wk and 32 ± 2.5 wk respectively (P < 0.001),a median overall survival (OS) time of 11 ± 1.2 mo and 19 ± 1.8 mo respectively (P < 0.001),as well as in 24 patients with negative PTEN expression and in 37 patients with positive PTEN expression respectively (P < 0.001),with a responsive rate of 4.2% and 48.6% respectively,a shorter median PFS survival time of 17 ± 2.0 wk and 28 ± 1.9 wk respectively (P=0.07),and a median OS time of 11 ± 1.3 mo and 18 ± 1.9 mo respectively (P=0.004).Combined KRAS mutation and PTEN expression analysis showed that the PFS and OS time of patients with two favorable prognostic factors were longer than those of patients with one favorable prognostic factor or no favorable prognostic factor (P < 0.001).CONCLUSION:KRAS mutation and PTEN protein expression are significantly correlated with the response rate and survival time of Chinese mCRC patients treated with cetuximab. | Fang-Hua Li,Zhuang-Hua Li,Hui-Yan Luo,Miao-Zhen Qiu,Yu-Hong Li,Rui-Hua Xu,State Key Laboratory of Oncology in Southern China,Department of Medical Oncology,Sun YatSen University Cancer Center,Guangzhou 510060,Guangdong Province,China Fang-Hua Li,Department of Medical Oncology,Shengli Oil Field Central Hospital,Dongying 257034,Shandong Province,China Lin Shen,Department of GI Oncology,Peking University School of Oncology,Beijing Cancer Hospital and Institute,Beijing 100142,China Hui-Zhong Zhang,State Key Laboratory of Oncology in Southern China,Department of Pathology,Sun Yat-Sen University Cancer Center,Guangzhou 510060,Guangdong Province,China | 2010 | World Journal of Gastroenterology2010，16，46： | 9 |
| 7 | Primary large cell neuroendocrine carcinoma in the common bile duct:First Asian case report显示文摘Large cell neuroendocrine carcinoma(LCNEC)in the biliary system is a poorly differentiated,high-grade neuroendocrine tumor.These tumors exhibit aggressive behavior and an increased tendency for early nodal and distant metastases.Herein,we report an unusual case of a pure primary LCNEC of the common bile duct(CBD).A 75-year-old female presented with nausea and jaundice.The patient underwent a CBD excision with lymph node dissection.Upon histological and immunohistochemical examination,the tumor exhibited pure large cell-type neuroendocrine features.Metastases were noted in two of the eight lymph nodes.The patient was administered adjuvant chemotherapy.The patient’s cancer recurred 7 mo after surgery,and the patient died from liver failure 5 mo after recurrence.The prognosis of LCNEC of CBD remains poor despitecurative resection and adjuvant chemotherapy.The role of additional therapies,such as multimodal treatment including radiation therapy,must be further studied to improve the prognoses of patients. | Sung Bae Park Suk Bae Moon Young Joon Ryu Jeana Hong Yang Hee Kim Gi Bong Chae Seong Kweon Hong | 2014 | World Journal of Gastroenterology2014，20，47： | 8 |
| 8 | Assessing cypermethrin-contaminated soil with three different earthworm test methods显示文摘A series of tests (lethal,sublethal,and behavioral) on earthworms were conducted as an eco-assessment of pesticides.In this study,the toxicity of cypermethrin-contaminating soil on adult and juvenile earthworms was assessed.Beside the acute and chronic tests,an avoidance response test was carried out.It was shown that the all-round toxicity from cypermethrin was weak on adult earthworms.Compared with adult earthworms,the toxicity of juvenile earthworms from cypermethrin especially chronic toxicity increased significantly.Growth and reproduction of earthworms appeared to be more severely affected by cypermethrin at juvenile stage than at adult stage.Applied at 10 mg/kg,cypermethrin had obvious adverse impact on the growth of juvenile earthworms,while 20 mg/kg,cypermethrin caused significant toxic effects in reproduction.The results also indicated that ecotoxicological risk assessment using only adult specimens may underestimate the effects of cypermethrin on soil invertebrate populations. | Wong Hang Gi Michelle | 2008 | Journal of Environmental Sciences2008，20，11： | 7 |

| 10 | 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 |
| 11 | Individual and combined toxic effects of cypermethrin and chlorpyrifos on earthworm显示文摘Toxicities were assessed for a pyrethroid (cypermethrin) and an organophosphate insecticide (chlorpyrifos) individually and in combination. A series of tests were conducted on different responses (acute, chronic, behavioral) of earthworms of species Eisenia fetida andrei in the ecological risk assessment of these pesticides. The results showed that the toxicity of the mixture of cypermethrin and chlorpyrifos was significantly higher than either of these pesticides individually, especially on the earthworm's chronic responses. At a concentration of 5 mg/kg, the mixture caused significant reductions on the growth and reproduction rates of earthworms, but did not cause any significant effect when the individual was tested. The increase in toxicity of the pesticide mixture means that the use of toxicity data obtained exclusively from single-pesticide experiments may underestimate the ecological risk of pesticides that actually present in the field. | Shiping Zhou Changqun Duan Wong Hang Gi Michelle Fazhong Yang Xuehua Wang | 2011 | Journal of Environmental Sciences2011，23，4： | 5 |
| 12 | Experimental investigation of friction coefficient in tube hydroforming显示文摘The friction coefficient between tube and die in guide zone of tube hydroforming was obtained. In hydroforming, the tube is expanded by an internal pressure against the tool wall. By pushing the tube through tool, a friction force at the contact surface between the tube and the tool occurs. In guiding zone, the friction coefficients between tube and die can be estimated from the measured axial feeding forces. In expansion zone, the friction coefficients between tube and die can be evaluated from the measured geometries of expanded tubes and FE analysis. | Hyae Kyung YI Hong Sup YIM Gun Yeop LEE Sung Mun LEE Gi Suk CHUNG Young-Hoon MOON | 2011 | Transactions of Nonferrous Metals Society of China2011，21，A01： | 5 |
| 13 | Emission properties of nanolasers during the transition to lasing显示文摘This review addresses ongoing discussions involving nanolaser experiments,particularly those related to thresholdless lasing or few-emitter devices.A quantum-optical(quantum-mechanical active medium and radiation field)theory is used to examine the emission properties of nanolasers under different experimental configurations.The active medium is treated as inhomogeneously broadened semiconductor quantum dots embedded in a quantum well,where carriers are introduced via current injection.Comparisons are made between a conventional laser and a nanolaser with a spontaneous emission factor of unity,as well as a laser with only a few quantum dots providing the gain.It is found that the combined exploration of intensity,coherence time,photon autocorrelation function and carrier spectral hole burning can provide a unique and consistent picture of nanolasers in the new regimes of laser operation during the transition from thermal to coherent emission.Furthermore,by reducing the number of quantum dots in the optical cavity,a clear indication of non-classical photon statistics is observed before the single-quantum-dot limit is reached. | Weng W Chow Frank Jahnke Christopher Gies | 2014 | Light(Science & Applications)2014，3，1： | 5 |
| 14 | Texture tailoring and bendability improvement of rolled AZ31 alloy using {10-12} twinning: The effect of precompression levels显示文摘In this study,the texture of a rolled Mg alloy is effectively modified through the application of precompression and subsequent annealing treatment,leading to a remarkable improvement in the bending formability of the alloy at room temperature.Precompression induces lattice reorientation through{10-12}twinning,and annealing treatment reduces the stored strain energy of the precompressed material,which results in the formation of a stable grain structure with two dominant texture components.With an increase in precompression,the tensile strain in the outer region of the bending samples is accommodated to a greater extent due to more pronounced{10-12}twinning and basal slip.As a result,the bending formability of the material at room temperature improves with greater precompression.The variation in microstructure,texture,and bending behavior in relation to the degree of precompression is discussed in detail. | Jong Un Lee Ye Jin Kim Sang-Hoon Kim Jeong Hun Lee Min-Seong Kim Shi-Hoon Choi Byoung Gi Moon Young Min Kim Sung Hyuk Park | 2019 | Journal of Magnesium and Alloys2019，7，4： | 5 |
| 15 | Surgical repair of intractable chylous ascites following laparoscopic anterior resection显示文摘Chylous ascites is the accumulation of a milk-like peritoneal fluid rich in triglycerides and it is an unusual complication following surgical treatment of colorectal cancer. Conservative management is usually sufficientin patients with chylous ascites after surgery. However,we describe a patient with intractable chylous ascites after laparoscopic anterior resection for sigmoid colon cancer who failed initial conservative treatment. This patient was successfully managed by surgery. | Gi Won Ha Min Ro Lee | 2015 | World Journal of Gastroenterology2015，21，19： | 5 |
| 16 | Intrauterine midgut volvulus without malrotation:Diagnosis from the 'coffee bean sign'显示文摘Fetal midgut volvulus is quite rare, and most cases are associated with abnormalities of intestinal rotation or fixation. We report a case of midgut volvulus without malrotation, associated with a meconium pellet, during the gestation period. This 2.79 kg, 33-wk infant was born via a spontaneous vaginal delivery caused by preterm labor. Prenatal ultrasound showed dilated bowel loops with the appearance of a 'coffee bean sign'. This patient had an unusual presentation with a distended abdomen showing skin discoloration. An emergency laparotomy revealed a midgut volvulus and a twisted small bowel, caused by complicated meconium ileus. Such nonspecific prenatal radiological signs and a low index of suspicion of a volvulus during gestation might delay appropriate surgical management and result in ischemic necrosis of the bowel. Preterm labor, specific prenatal sonographic findings (for example, the coffee bean sign) and bluish discoloration of the abdominal wall could suggest intrauterine midgut volvulus requiring prompt surgical intervention. | Jun Seok Park Seong Jae Cha Beom Gyu Kim Yong Seok Kim Yoo Shin Choi In Taik Chang Gwang Jun Kim Woo Seok Lee Gi Hyeon Kim | 2008 | World Journal of Gastroenterology2008，14，9： | 4 |
| 17 | Subacute electroacupuncture at Baihui (GV 20) and Dazhui (GV 14) promotes post-stroke functional recovery via neurogenesis and astrogliosis in a photothrombotic stroke mouse model显示文摘OBJECTIVE:To investigate the optimal timing and underlying mechanism of electroacupuncture(EA)at Baihui(GV 20)and Dazhui(GV 14)for improved long-term functional recovery after focal cerebral ischemia in a photothrombotic stroke mouse model.METHODS:Totally 50 adult male C57 BL/6 J mice were assigned into 5 groups:(a)the control group,sham-operated mice(n=10);(b)the vehicle group,focal cerebral ischemia induction without EA(n=10);(c)the acute EA group,mice received EA immediately post-ischemia,followed by once-daily treatments for 7 consecutive days(n=10);(d)the subacute EA group,mice received EA 4 days post-ischemia,followed by once-daily treatments for 7 consecutive days(n=10);(e)the delayed EA group.EA stimulation(2 Hz,2 V for 20 min)was applied to acupuncture points(acupoints),Baihui(GV 20)and Dazhui(GV 14),once a day for 7 consecutive days beginning immediately(acute treatment),4 d(subacute treatment)and 10 d(delayed treatment)after focal cerebral ischemia in C57 BL/6 J mice.Behavioral assessments were conducted 21 and 28 d post-ischemia and histopathological analyses were performed 28 days post-ischemia.RESULTS:The subacute EA treatment at Baihui(GV20)and Dazhui(GV 14)significantly improved functional recovery compared to the vehicle group 28 d after ischemic brain injury,although brain atrophy was not reduced.The number of Neu N+and Neu N+/Brd U+cells as well as GFAP intensity in the ipsilateral cortex were significantly increased in the subacute group compared to the vehicle group 28 d post-ischemia.We concluded that EA stimulation 4 d post-ischemia(subacute treatment)enhanced neurogenesis and astrogliosis,likely contributing to long-term functional recovery following focal cerebral ischemia.CONCLUSION:Our findings suggest that the timing of the EA therapy at Baihui(GV 20)and Dazhui(GV 14)determines the therapeutic effects in mice with focal cerebral ischemia induced by photothrombotic occlusion. | Young-Wook Park Gi Yoon Heo Min Jae Kim Seo-Yeon Lee Byung Tae Choi Hwa Kyoung Shin | 2019 | Journal of Traditional Chinese Medicine2019，39，6： | 4 |
| 18 | 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 |
| 19 | Cholecystocolic fistula caused by gallbladder carcinoma:Preoperatively misdiagnosed as hepatic colon carcinoma显示文摘Cholecystocolic fistula secondary to gallbladder carcinoma is extremely rare and has been reported in very few studies. Most cholecystocolic fistulae are late complications of gallstone disease, but can also develop following carcinoma of the gallbladder when the necrotic tumor penetrates into the adjacent colon. Although no currently available imaging technique has shown great accuracy in recognizing cholecystocolic fistula, abdominopelvic computed tomography may show fistulous communication and anatomical details.Herein we report an unusual case of cholecystocolic fistula caused by gallbladder carcinoma, which was preoperatively misdiagnosed as hepatic flexure colon carcinoma. | Gi Won Ha Min Ro Lee Jong Hun Kim | 2015 | World Journal of Gastroenterology2015，21，15： | 3 |
| 20 | High prevalence of osteoporosis in patients with gastric adenocarcinoma following gastrectomy显示文摘AIM: To evaluate the prevalence and predictive factors of osteoporosis in patients with gastric adenocarcinoma after gastrectomy. METHODS: The study included 133 patients diagnosed with gastric adenocarcinoma but who did not undergo prior diagnostic work-up for osteoporosis. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry (DXA) and vertebral deformity was assessed by plain X-rays. We evaluated the effects of age, sex, body mass index (BMI), anemia, back pain, vertebral deformity, tumor staging, reconstruction type, and past medical history to determine predictive factors of osteoporosis in these patients. RESULTS: The prevalence of osteoporosis in the lumbar spine was 38.3% (male, 28.9%; female, 54.0%), and 15.0% in the femoral neck (male, 10.8%; female, 22.0%). The vertebral deformity rate was 46.6% (male, 43.4%; female, 52.0%). Age, BMI and hemoglobin correlated with BMD (P < 0.01). In males, anemia and age > 64 years were independent predictive factors of osteoporosis in multivariate analysis. In females, back pain was an independent factor for osteoporosis. CONCLUSION: The results of this study revealed that prevalence of osteoporosis and vertebral bone deformity rate were high in gastric cancer patients, regardless of post-gastrectomy duration and operation type. Early diagnosis and a proper management plan must be established in these patients. | Jung Sub Lim Sang Bum Kim Ho-Yoon Bang Gi Jeong Cheon Jong-Inn Lee | 2007 | World Journal of Gastroenterology2007，13，48： | 3 |
