| 1 | Diagnostic value of PIVKA-Ⅱ and alpha-fetoprotein in hepatitis B virus-associated hepatocellular carcinoma显示文摘AIM: To determine the cutoff values and to compare the diagnostic role of alpha-fetoprotein(AFP) and prothrombin induced by vitamin K absence-Ⅱ(PIVKA-Ⅱ) in chronic hepatitis B(CHB).METHODS: A total of 1255 patients with CHB, including 157 patients with hepatocellular carcinoma(HCC), 879 with non-cirrhotic CHB and 219 with cirrhosis without HCC, were retrospectively enrolled. The areas under the receiver operating characteristic(AUROC) curves of PIVKA-Ⅱ, AFP and their combination were calculated and compared.RESULTS: The optimal cutoff values for PIVKA-Ⅱ and AFP were 40 m AU/m L and 10 ng/m L, respectively, for the differentiation of HCC from nonmalignant CHB. The sensitivity and specificity were 73.9% and 89.7%, respectively, for PIVKA-Ⅱ and 67.5% and 90.3% for AFP, respectively. The AUROC curves of both PIVKA-Ⅱ and AFP were not significantly different(0.854 vs 0.853, P = 0.965) for the differentiation of HCC from nonmalignant CHB, whereas the AUROC of PIVKA-Ⅱ was significantly better than that of AFP in patients with cirrhosis(0.870 vs 0.812, P = 0.042). When PIVKA-Ⅱ and AFP were combined, the diagnostic power improved significantly compared to either AFP or PIVKA-Ⅱ alone for the differentiation of HCC from nonmalignant CHB(P < 0.05), especially when cirrhosis was present(P < 0.05).CONCLUSION: Serum PIVKA-Ⅱ might be a better tumor marker than AFP, and its combination with AFP may enhance the early detection of HCC in patients with CHB. | Seung In Seo Hyoung Su Kim Won Jin Kim Woon Geon Shin Doo Jin Kim Kyung Ho Kim Myoung Kuk Jang Jin Heon Lee Joo Seop Kim Hak Yang Kim Dong Joon Kim Myung Seok Lee Choong Kee Park | 2015 | World Journal of Gastroenterology2015，21，13： | 60 |
| 2 | Evolution of laparoscopy in colorectal surgery:An evidencebased review显示文摘Open surgery for colorectal disease has progressed significantly over the past century from humble beginnings to form the mainstay of treatment for colorectal cancer and a number of benign conditions.Following the introduction of laparoscopic abdominal surgery,the next stage in the evolution of the specialty began in the 1990s with the first laparoscopic colonic resection.Following some early concerns regarding its safety and oncological efficacy during the latter part of that decade,laparoscopic colorectal surgery rapidly came into mainstream use in the early part of the current century with evidence supporting its use being made available from large scale randomised controlled trials.This article provides an evidence-based summary of this evolutionary process as it relates to both benign and malignant colorectal disease,as well as discussion of the next phase of new technologies such as robotic surgery. | Alexander Emmanuel Blackmore Mark Te Ching Wong Choong Leong Tang | 2014 | World Journal of Gastroenterology2014，20，17： | 12 |
| 3 | Toothpick impaction with sigmoid colon pseudodiverticulum formation successfully treated with colonoscopy显示文摘Foreign bodies in the colon are encountered with increasing frequency, but only sporadic reports concerning their management have appeared in the literature. While most ingested foreign bodies usually pass through the gastrointestinal tract uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal perforation and may even result in death. We report our experience with a patient with a sigmoid colon pseudodiverticulum formation, a complication of accidental ingestion of a toothpick that was diagnosed and successfully managed colonoscopically. | Youn Son Chung Yong Woo Chung Sun You Moon Su Mi Yoon Min-Jeong Kim Kyoung Oh Kim Cheol Hee Park Taeho Hahn Kyo-Sang Yoo Sang Hoon Park Jong Hyeok Kim Choong Kee Park | 2008 | World Journal of Gastroenterology2008，14，6： | 10 |
| 4 | Impact of tumor location on clinical outcomes of gastric endoscopic submucosal dissection显示文摘AIM:To determine whether there is a correlation between the location of the lesion and endoscopic submucosal dissection(ESD)outcome.METHODS:From January 2008 to December 2010,ESD of 1443 gastric tumors was performed.En bloc resection rate,complete resection rate,procedure time and complication rate were analyzed according to the tumor location.RESULTS:The rates of en bloc resection and complete resection were 91%(1318/1443)and 89%(1287/1443),respectively.The post-ESD bleeding rate was 4.3%,and perforation rate was 2.7%.Tumors located in the upper third of the stomach were associated with a longer procedure time and significantly higher rates of incomplete resection,piecemeal resection,and perforation than tumors below the upper third of the stomach.Posterior wall lesions had significantly longer procedure times and higher rates of incomplete resection and piecemeal resection than lesions in other locations.In multivariate analysis,posterior wall lesions and upper third lesions were significantly associated with incomplete resection and perforation,respectively.In post-ESD bleeding analysis,location was not a significant related factor.CONCLUSION:More advanced endoscopic techniques are required during ESD for lesions located in the upper third or posterior wall of the stomach to decrease complications and improve therapeutic outcomes. | Ji Young Yoon Choong Nam Shim Sook Hee Chung Wan Park Hyunsoo Chung Hyuk Lee Sung Kwan Shin Sang Kil Lee Yong Chan Lee Jun Chul Park | 2014 | World Journal of Gastroenterology2014，20，26： | 10 |
| 5 | Endoscopic submucosal dissection for undifferentiated-type early gastric cancer: Do we have enough data to support this?显示文摘Although endoscopic submucosal dissection(ESD)is now accepted for treatment of early gastric cancers(EGC)with negligible risk of lymph node(LN)metastasis,ESD for intramucosal undifferentiated type EGC without ulceration and with diameter≤2 cm is regarded as an investigational treatment according to the Japanese gastric cancer treatment guidelines.This consideration was largely based on the analysis of surgically resected EGCs that contained undifferentiated type EGCs;however,results from several institutes showed some discrepancies in sample size and incidence of LN metastasis.Recently,some reports about the safety and efficacy of ESD for undifferentiated type EGC meeting the expanded criteria have been published.Nonetheless,only limited data are available regarding long-term outcomes of ESD for EGC with undifferentiated histology so far.At the same time,endoscopists cannot ignore the patients’desire to guarantee quality of life after the relatively non-invasive endoscopic treatment when compared to conventional surgery.To satisfy the needs of patients and provide solid evidence to support ESD for undifferentiated EGC,we need more delicate tools to predict undetected LN metastasis and more data that can reveal predictive factors for LN metastasis. | Choong Nam Shim Sang Kil Lee | 2014 | World Journal of Gastroenterology2014，20，14： | 10 |

| 10 | Signet-ring cell carcinoma arising from a fundic gland polyp in the stomach显示文摘Fundic gland polyps(FGPs)are currently the most common type of gastric polyps and are usually benign.However,although rare,gastric adenocarcinoma of FGP has been recently proposed as a new variant of gastric adenocarcinoma.Here we report the first case of a49-year-old woman with focal signet ring cell carcinoma that arose from an FGP of the stomach.The tumor was completely excised by endoscopic snare polypectomy.FGPs should therefore be evaluated for malignant changes although they occur rarely,if the FGP has an erosive or irregular surface. | Yong Seol Jeong Sung Eun Kim Mi-Jung Kwon Jae Yong Seo Hyun Lim Ji Won Park Ho Suk Kang Sung Hoon Moon Jong Hyuk Kim Choong Kee Park | 2014 | World Journal of Gastroenterology2014，20，47： | 6 |
| 11 | Nasal metastases from renal cell carcinoma are associated with Memorial Sloan-Kettering Cancer Center poor-prognosis classification显示文摘Unusual sites of metastases are recognized in patients with renal cell carcinoma (RCC). However, the prognostic implications of these sites are not well understood. We used the Memorial Sloan-Kettering Cancer Center (MSKCC) risk classification for metastatic RCC to evaluate 912 consecutive patients with RCC managed at the Singapore General Hospital between 1990 and 2009. Among these patients, 301 had metastases either at diagnosis or during the course of illness. Nasal metastases, all arising from clear cell RCC, were identified histologically in 4 patients (1.3% of those with metastasis). All 4 patients were classified as MSKCC poor prognosis by current risk criteria. Nasal metastases were significantly associated with lung and bone metastases. The frequency of nasal metastases in patients with metastatic RCC is about 1%, occurring predominantly in patients with clear cell RCC. Nasal metastases are associated with poor prognosis as estimated by the MSKCC risk classification, with attendant implications for selection of targeted therapy, and are usually associated with multi-organ dissemination, including concurrent lung and bone involvement. | Caroline Victoria Choong Tiffany Tang Wen Yee Chay Christopher Goh Miah Hiang Tay Nor Azhari Mohd Zam Puay Hoon Tan Min-Han Tan | 2011 | Chinese Journal of Cancer2011，30，2： | 6 |

| 13 | Wearable sensors for 3D upper limb motion modeling and ubiquitous estimation显示文摘Human motion capture technologies are widely used in interactive game and learning, animation, film special effects, health care, and navigation. Because of the agility, upper limb motion estimation is the most difficult problem in human motion capture. Traditional methods always assume that the movements of upper arm and forearm are independent and then estimate their movements separately; therefore, the estimated motion are always with serious distortion. In this paper, we propose a novel ubiquitous upper limb motion estimation method using wearable microsensors, which concentrates on modeling the relationship of the movements between upper arm and forearm. Exploration of the skeleton structure as a link structure with 5 degrees of freedom is firstly proposed to model human upper limb motion. After that, parameters are defined according to Denavit-Hartenberg convention, forward kinematic equations of upper limb are derived, and an unscented Kalman filter is invoked to estimate the defined parameters. The experimental results have shown the feasibility and effectiveness of the proposed upper limb motion capture and analysis algorithm. | Zhang, Zhiqiang Wong, Wai Choong Wu, Jiankang | 2011 | 控制理论与应用(英文版)2011，9，1： | 5 |

| 16 | Does the discrepancy in histologic differentiation between a forceps biopsy and an endoscopic specimen necessitate additional surgery in early gastric cancer?显示文摘AIM To investigate the clinicopathological variables in early gastric cancer(EGC) patients in relation to differentiation discrepancy.METHODS The data of 265 specimens from 240 patients with EGC, who had undergone radical operation at Hallym University Sacred Heart Hospital from 2010 to 2015, were retrospectively analyzed. We evaluated clinical, endoscopic, and histopathological data according to histological discrepancy.RESULTS Clinically significant discrepancy rate showed the difference in differentiated type(well and moderately differentiated) and undifferentiated type(poorly differentiated and signet ring cell) between endoscopic biopsies and postoperative specimens was 9.4%(25/265). There were no differences in tumor location, size, gross pattern, and number of biopsies. Specimens having histological discrepancy showed more submucosal invasion(72.0% vs 49.6%, P = 0.033) and lymph node involvement(24.0% vs 7.9%, P = 0.009) than specimens having non-discrepancy. The rate of a positive epidermal growth factor receptor status was higher in specimens having discrepancy than in specimens having non-discrepancy(81.0% vs 55.4%, P = 0.035).CONCLUSION The discordance of histologic differentiation is associated with higher submucosal invasion and lymph node metastases in EGC. Patients have histological discrepancy may require additional surgical treatments. | Jae Seung Soh Hyun Lim Ho Suk Kang Jong Hyeok Kim Kab Choong Kim | 2017 | World Journal of Gastrointestinal Oncology2017，9，8： | 4 |
| 17 | Differentiation of acute and chronic hepatitis B in IgM antiHBc positive patients显示文摘AIM: To identify the factors that differentiate acute hepatitis B(AHB) from chronic hepatitis B with acute exacerbation(CHB-AE).METHODS: From 2004 to 2013, a total of 82 patients(male n = 52, 63.4%; female n = 30, 36.6%) with clinical features of acute hepatitis with immunoglobulin M antibodies to the hepatitis B core antigen(Ig M antiHBc) were retrospectively enrolled and divided into two groups; AHB(n = 53) and CHB-AE(n = 29). The AHB group was defined as patients without a history of hepatitis B virus(HBV) infection before the episode and with loss of hepatitis B surface antigen within 6 mo after onset of acute hepatitis. Biochemical and virological profiles and the sample/cutoff(S/CO) ratio of Ig M anti-HBc were compared to determine the differential diagnostic factors.RESULTS: The multivariate analysis demonstrated that, the S/CO ratio of Ig M anti-HBc and HBV DNA levels were meaningful factors. The S/CO ratio of Ig M anti-HBc was significantly higher in the AHB group, while the HBV DNA level was significantly higher in the CHB-AE group. The optimal cutoff values of Ig M anti-HBc and HBV DNA levels for differentiating the two conditions were 8 S/CO ratio and 5.5 log10 IU/m L, respectively. The sensitivity and specificity were 96.2% and 89.7% for the S/CO ratio of Ig M anti-HBc and 81.1% and 72.4% for HBV DNA levels, respectively. The area under receiver operating characteristic curves of both the S/CO ratio of Ig M anti-HBc and HBV DNA levels were not significantly different(0.933 vs 0.844, P = 0.105). When combining Ig M anti-HBc and HBV DNA, the diagnostic power significantly improved compared to HBV DNA alone(P = 0.0056). The combination of these factors yielded a sensitivity and specificity of 98.1% and 86.2%, respectively.CONCLUSION: The combination of the S/CO ratio of Ig M anti-HBc and HBV DNA levels was a useful tool for differentiating AHB from CHB-AE in patients with positive Ig M anti-HBc. | Ji Won Park Kyeong Min Kwak Sung Eun Kim Myoung Kuk Jang Dong Joon Kim Myung Seok Lee Hyoung Su Kim Choong Kee Park | 2015 | World Journal of Gastroenterology2015，21，13： | 4 |
| 18 | Univector field method-based multi-agent navigation for pursuit problem in obstacle environments显示文摘The pursuit problem is a well-known problem in computer science. In this problem, a group of predator agents attempt to capture a prey agent in an environment with various obstacle types, partial observation, and an infinite grid-world. Predator agents are applied algorithms that use the univector field method to reach the prey agent, strategies for avoiding obstacles and strategies for cooperation between predator agents. Obstacle avoidance strategies are generalized and presented through strategies called hitting and following boundary(HFB); trapped and following shortest path(TFSP); and predicted and following shortest path(PFSP). In terms of cooperation, cooperation strategies are employed to more quickly reach and capture the prey agent. Experimental results are shown to illustrate the efficiency of the method in the pursuit problem. | Le Pham Tuyen Hoang Huu Viet Sang Hyeok An Seung Gwan Lee Dong-Han Kim Tae Choong Chung | 2017 | Journal of Central South University2017，24，4： | 3 |

| 20 | Gallbladder lymphangioma:A case report and review of the literature显示文摘Lymphangiomas are rare, benign tumors of the lymphatic system, usually present in children aged 5 years and younger. Because they are asymptomatic until the mass enlarges to cause symptoms, most lymphangiomas are diagnosed at adulthood incidentally. We experienced a case of a 60-year-old man diagnosed with a cystic lymphangioma of the gallbladder, which was successfully resected without any complication. Magnetic resonance imaging and magnetic resonance cholangiopancreatography were very helpful for the diagnosis of the cystic lesion around the gallbladder as were ultrasonography and computed tomography scan. These showed a multi-lobulated cystic mass with intact cystic duct and bile duct in the gallbladder fossa. The patient underwent an open cholecystectomy and the histological findings were consistent with a cystic lymphangioma of the gallbladder. We here report the case of cystic lymphangioma of the gallbladder with a review of the literature. | Jwa-Kyung Kim Kyo-Sang Yoo Joon Ho Moon Kwang Hyuk Park Yong Woo Chung Kyoung Oh Kim Cheol Hee Park Taeho Hahn Sang Hoon Park Jong Hyeok Kim Jang Yeong Jeon Min Jung Kim Kwang Seon Min Department of Pathology Hallym University College of Medicine Anyang Korea Choong Kee Park | 2007 | World Journal of Gastroenterology2007，13，2： | 3 |
