| 1 | Limited endoscopic sphincterotomy plus large balloon dilation for choledocholithiasis with periampullary diverticula显示文摘AIM: To investigate the effectiveness and safety of limited endoscopic sphincterotomy (EST) plus large balloon dilation (LBD) for removing choledocholithiasis in patients with periampullary diverticula (PAD). METHODS: A total of 139 patients with common bile duct (CBD) stones were treated with LBD (10-20 mm balloon diameter) after limited EST. Of this total, 73 patients had PAD and 66 patients did not have PAD (controls). The results of stone removal and complications were retrospectively evaluated. RESULTS: There were no significant differences between the PAD and the control groups in overall successful stone removal (94.5% vs 93.9%), stone removal in first session (69.9% vs 81.8%), mechanical lithotripsy (12.3% vs 13.6%), and complications (11.0% vs 7.6%). Clinical outcomes were also similar between the types of PAD, but the rate of stone removal in first session and the number of sessions were significantly lower and more frequent, respectively, in type B PAD (papilla located near the diverticulum) than controls [23/38 (60.5%) vs 54/66 (81.8%), P = 0.021; and 1 (1-2) vs 1 (1-3), P = 0.037, respectively] and the frequency of pancreatitis was significantly higher in type A PAD (papilla located inside or in the margin of the diverticulum) than in controls (16.1% vs 3.0%, P = 0.047). CONCLUSION: Limited EST plus LBD was an effective and safe procedure for removing choledocholithiasis in patients with PAD. However, some types of PAD should be managed with caution. | Hyung Wook Kim Dae Hwan Kang Cheol Woong Choi Jong Hwan Park Jin Ho Lee Min Dae Kim Il Doo Kim Ki Tae Yoon Mong Cho Ung Bae Jeon Suk Kim Chang Won Kim Jun Woo Lee | 2010 | World Journal of Gastroenterology2010，16，34： | 26 |

| 3 | Dysphagia in patients with isolated pontine infarction显示文摘Little is known about dysphagia after pontine infarction. In this study, we evaluated the incidence of dysphagia after isolated pontine infarction and identified the predictive factors for the occurrence of dysphagia. A total of 146 patients were included in this study. All patients underwent clinical testing for dysphagia within 1 day after admission and at the time of discharge. We compared the incidence of dysphagia between patients with unilateral pontine infarction and those with bilateral pontine infarction. To evaluate the functional status of patients, we investigated their initial modified Rankin Scale(mRS) score and initial National Institutes of Health Stroke Scale(NIHSS) score within 1 day of admission. Of 146 patients, 50(34.2%) had dysphagia initially within 1 day after admission. At the second evaluation at the time of discharge, dysphagia was diagnosed in 24 patients(16.4%). Patients with bilateral pontine infarction were more likely to present with dysphagia. In addition, clinical severity(in terms of mRS and NIHSS scores) was identified as a predictor of dysphagia in patients with cerebral infarction(multiple binary logistic regression analysis, mRS: P = 0.011, NIHSS: P = 0.004). Dysphagia frequently occurs in patients with isolated pontine infarction. Clinicians should pay particular attention to the occurrence of dysphagia, especially in patients with bilateral pontine infarction or high functional disability. | Min Cheol Chang Sang Gyu Kwak Min Ho Chun | 2018 | Neural Regeneration Research2018，13，12： | 11 |
| 4 | Differentiation of hepatocellular carcinoma from its variousmimickers in liver magnetic resonance imaging:What arethe tips when using hepatocyte-specific agents?显示文摘Hepatocellular carcinoma is the most common primary hepatic malignant tumor.With widespread use of liver imaging,various cirrhosis-related nodules are frequently detected in patients with chronic liver disease,while diverse hypervascular hepatic lesions are incidentally detected but undiagnosed on dynamic computed tomography and magnetic resonance imaging(MRI).However,use of hepatocyte-specific MR contrast agents with combined perfusion and hepatocyte-selective properties have improved diagnostic performance in detection and characterization of focal liver lesions.Meanwhile,the enhancement patterns observed during dynamic phases using hepatocyte-specific agents may be different from those observed during MRI using conventional extracellular fluid agents,leading to confusion in diagnosis.Therefore,we discuss useful tips for the differentiation of hepatocellular carcinoma from similar lesions in patients with and without chronic liver disease using liver MRI with hepatocyte-specific agents. | Yang Shin Park Chang Hee Lee Jeong Woo Kim Sora Shin Cheol Min Park | 2016 | World Journal of Gastroenterology2016，22，1： | 10 |
| 5 | Prediction of liver cirrhosis, using diagnostic imaging tools显示文摘Early diagnosis of liver cirrhosis is important. Ultrasoundguided liver biopsy is the gold standard for diagnosis of liver cirrhosis. However, its invasiveness and sampling bias limit the applicability of the method. Basic imaging for the diagnosis of liver cirrhosis has developed over the last few decades, enabling early detection of morphological changes of the liver by ultrasonography(US), computed tomography, and magnetic resonance imaging(MRI). They are also accurate diagnostic methods for advanced liver cirrhosis, for which early diagnosis is difficult. There are a number of ways to compensate for this difficulty, including texture analysis to more closely identify the homogeneity of hepatic parenchyma, elastography to measure the stiffness and elasticity of the liver, and perfusion studies to determine the blood flow volume, transit time, and velocity. Amongst these methods, elastography using US and MRI was found to be slightly easier, faster, and able to provide an accurate diagnosis. Early diagnosis of liver cirrhosis using MRI or US elastography is therefore a realistic alternative, but further research is still needed. | Suk Keu Yeom Chang Hee Lee Sang Hoon Cha Cheol Min Park | 2015 | World Journal of Hepatology2015，7，17： | 9 |
| 6 | Early treadmill exercise increases macrophage migration inhibitory factor expression after cerebral ischemia/reperfusion显示文摘The neuroprotective function of macrophage migration inhibitory factor(MIF) in ischemic stroke was rarely evaluated.This study aimed to investigate the effects of early treadmill exercise on recovery from ischemic stroke and to determine whether these effects are associated with the expression levels of MIF and brain-derived neurotrophic factor(BDNF) in the ischemic area.A total of 40 male Sprague-Dawley rats were randomly assigned to the ischemia and exercise group [middle cerebral artery occlusion(MCAO)-Ex,n = 10),ischemia and sedentary group(MCAO-St,n = 10),sham-surgery and exercise group(Sham-Ex,n= 10),or sham-surgery and sedentary group(Sham-St,n = 10).The MCAO-Ex and MCAO-St groups were subjected to MCAO for 60 minutes,whereas the Sham-Ex and Sham-St groups were subjected to an identical operation without MCAO.Rats in the MCAO-Ex and Sham-Ex groups then ran on a treadmill for 30 minutes once a day for 5 consecutive days.After reperfusion,the hanging time tested by the wire hang test was longer and the relative fractional anisotropy determined by MRI was higher in the peri-infarct region of the MCAO-Ex group compared with the MCAO-St group.The expression levels of MIF and BDNF in the peri-infarct region were upregulated in the MCAO-Ex group.Increased MIF and BDNF levels were positively correlated with relative fractional anisotropy changes in the peri-infarct region.There was no significant difference in the levels of MIF and BDNF in the peri-infarct region between the Sham-Ex and Sham-St groups.Our study demonstrated that early exercise(initiated 48 hours after the MCAO) could improve motor and neuronal recovery after ischemic stroke.Furthermore,the increased levels of MIF and BDNF in the peri-infarct region(penumbra) may be one of the mechanisms of enhanced neurological function recovery.All experiments were approved by the Institutional Animal Care and Use Committee in Asan Medical Center in South Korea(2016-12-126). | Min Cheol Chang Chae Ri Park Seung Hwa Rhie Woo Hyun Shim Dae Yul Kim | 2019 | Neural Regeneration Research2019，14，7： | 7 |
| 7 | Clinical and endoscopic characteristics of drug-induced esophagitis显示文摘AIM: To investigate clinical, endoscopic and pathological characteristics of drug-induced esophagitis.METHODS: Data for patients diagnosed with drug-induced esophagitis from April 2002 to May 2013 was reviewed. Patients diagnosed with malignancy, viral or fungal esophagitis were excluded. Clinical, endoscopic and pathological characteristics of patients diagnosed with drug-induced esophagitis were analyzed.RESULTS: Seventy-eight patients were diagnosed with drug-induced esophagitis. Their mean age was 43.9 ± 18.9 years and 35.9% were male. Common symptoms were chest pain(71.8%), odynophagia(38.5%) and dysphagia(29.5%). The endoscopic location was in the middle third of esophagus in 78.2%. Endoscopic findings were ulcer(82.1%), erosion(17.9%), ulcer with bleeding(24.4%), coating with drug material(5.1%), impacted pill fragments(3.8%) and stricture(2.6%). Kissing ulcers were observed in 43.6%. The main causative agents were antibiotics and non-steroidal antiinflammatory drugs. All the patients were treated with proton pump inhibitors(PPIs) or sucralfate, and the causative drugs were discontinued. Nineteen patients with drug-induced esophagitis were followed up with endoscopy and revealed normal findings, scars or healing ulcers.CONCLUSION: Drug-induced esophagitis mainly presents as chest pain, odynophagia and dysphagia, and may be successfully treated with PPIs and discontinuation of the causative drug. Kissing ulcers were observed in 43.6%. | Su Hwan Kim Ji Bong Jeong Ji Won Kim Seong-Joon Koh Byeong Gwan Kim Kook Lae Lee Mee Soo Chang Jong Pil Im Hyoun Woo Kang Cheol Min Shin | 2014 | World Journal of Gastroenterology2014，20，31： | 7 |
| 8 | Correlation of fatty liver and abdominal fat distribution using a simple fat computed tomography protocol显示文摘AIM: To evaluate the relationship between hepatic fat infiltration and abdominal fat volume by using computed tomography (CT).METHODS: Three hundred and six patients who visited our obesity clinic between November 2007 and April 2008 underwent fat protocol CT scans.The age range of the patients was 19 to 79 years and the mean age was 49 years.The male to female ratio was 116:190.Liver and spleen attenuation measurements were taken with three regions of interests (ROIs) from the liver and two ROIs from the spleen.Hepatic attenuation indices (HAIs) were measured as follows: (1) hepatic parenchymal attenuation (CTLP);(2) liver to spleen attenuation ratio (LS ratio);and (3) difference between hepatic and splenic attenuation (LSdif).Abdominal fat volume was measured using a 3 mm slice CT scan starting at the level of the umbilicus and was automatically calculated by a workstation.Abdominal fat was classified into total fat (TF),visceral fat (VF),and subcutaneous fat (SF).We used a bivariate correlation method to assess the relationship between the three HAIs and TF,VF,and SF.RESULTS: There were significant negative correlations between CTLP,LS ratio,and LSdif with TF,VF,and SF,respectively.The CTLP showed a strong negative correlation with TF and VF (r = -0.415 and -0.434,respectively,P < 0.001).The correlation between CTLP and SF was less significant (r = -0.313,P < 0.001).CONCLUSION: Fatty infiltration of the liver was correlated with amount of abdominal fat and VF was more strongly associated with fatty liver than SF. | Seonah Jang Chang Hee Lee Kyung Mook Choi Jongmee Lee Jae Woong Choi Kyeong Ah Kim Cheol Min Park | 2011 | World Journal of Gastroenterology2011，17，28： | 5 |
| 9 | Motor outcomes of patients with a complete middle cerebral artery territory infarct显示文摘Detailed knowledge of motor outcomes enables to establish proper goals and rehabilitation strate-gies for stroke patients. Several previous studies have reported functional or motor outcomes in patients with a middle cerebral artery territory infarct. However, little is known about motor outcome in patients with a complete middle cerebral artery territory infarct. In this study, we investigated the motor outcomes in 23 patients with a complete middle cerebral artery territory infarct. All of these patients received comprehensive rehabilitative management, including movement therapy and neuromuscular electrical stimulation of the affected finger extensors and ankle dorsiflexors, for more than 3 months. Motor outcomes were measured at 6 months after stroke onset using the Medical Research Council, Motricity Index, the modified Brunnstrom Classification, and Functional Ambula-tion Category scores. The motor function of the lower extremities was found to be better than that of the upper extremities. After receiving rehabilitation treatments for 3-6 months, about 70% of these patients were able to walk independently (Functional Ambulation Category scores > 3), but no pa-tient achieved functional hand recovery. | Sung Ho Jang Min Cheol Chang | 2013 | Neural Regeneration Research2013，8，20： | 4 |
| 10 | Effects of pulsed radiofrequency on spasticity in patients with spinal cord injury:a report of two cases显示文摘Spasticity following spinal cord injury(SCI) results in functional deterioration and reduced quality of life. Herein, we report two SCI patients who presented with good response to pulsed radiofrequency(PRF) for the management of spasticity in the lower extremities. Patient 1(a 47-year-old man) had complete thoracic cord injury and showed a phasic spasticity on the extensor of both knees(3–4 beats clonus per every 30 seconds) and tonic spasticity(Modified Ashworth Scale: 3) on both hip adductors. Patient 2(a 64-yearold man) had incomplete cervical cord injury and showed a right ankle clonus(approximately 20 beats) when he walked. After the application of PRF to both L2 and L3 dorsal root ganglion(DRG)(patient 1) and right S1 DRG(patient 2) with 5 Hz and 5 ms pulsed width for 360 seconds at 45 V under the C-arm guide, all spasticity disappeared or was reduced. Moreover, the effects of PRF were sustained for approximately 6 months with no side effects. We believe that PRF treatment can be useful for patients with spasticity after SCI. | Min Cheol Chang Yun Woo Cho | 2017 | Neural Regeneration Research2017，12，6： | 3 |
| 11 | Sex-based differences in histology,staging,and prognosis among 2983 gastric cancer surgery patients显示文摘BACKGROUND Few studies have been conducted on sex differences in the incidence, pathophysiology, and prognosis of gastric cancer(GC).AIM To analyze the differences in GC characteristics according to sex in patients who underwent surgical treatment for GC.METHODS A total of 2983 patients diagnosed with gastric adenocarcinoma who received surgical treatment at the Seoul National University Bundang Hospital between 2003 and 2017 were included.Baseline clinicopathological characteristics, histologic type of GC, overall and GC-specific survival rates, and associated risk factors were analyzed.RESULTS Among the 2983 patients, 2005(67.2%) and 978(32.8%) were males and females, respectively.The average age of the female group(59.36 years) was significantly younger than that of the male group(61.66 years;P < 0.001).Cancer of the gastric body(P < 0.001) and diffuse-type histology(P < 0.001) were more common in females than in males.This trend was more prominent in females younger than 60 years of age, with a significantly higher proportion of diffuse-type cancer than in the male group.Regardless of sex, diffuse-type GC was more common in younger patients, and the proportion of intestinal-type GC increased with age.The overall survival rate was significantly higher in females(P < 0.001).However, this difference disappeared for GC-specific survival(P = 0.168), except for the poor GC-specific survival rate in advanced-stage cancer(stage Ⅲ or above) in females(P = 0.045).The risk factors for GC-related mortality were older age, upper location of GC, and diffuse-or mixed-type histology.In terms of comorbidities, more males died from diseases other than GC, including other malignancies such as lung cancer, hepatocellular carcinoma, and pancreatic cancer, and respiratory diseases such as interstitial lung disease and chronic obstructive pulmonary disease, while there were relatively more cardiovascular or cerebrovascular deaths in females.CONCLUSION Sex-based differences in GC were observed in clinicopathological features, including age at diagnosis, tumor location, histologic type, survival rate, and comorbidities. | Yonghoon Choi Nayoung Kim Ki Wook Kim Hyeong Ho Jo Jaehyung Park Hyuk Yoon Cheol Min Shin Young Soo Park Dong Ho Lee Hyeon Jeong Oh Hye Seung Lee Young Suk Park Sang-Hoon Ahn Yun-Suhk Suh Do Joong Park Hyung-Ho Kim Ji-Won Kim Jin Won Kim Keun-Wook Lee Won Chang Ji HoonPark Yoon Jin Lee Kyoung Ho Lee Young Hoon Kim | 2022 | World Journal of Gastroenterology2022，28，9： | 2 |
| 12 | Orthotic approach to prevention and management of diabetic foot:A narrative review显示文摘Diabetic foot is a common complication affecting more than one-fifth of patients with diabetes.If not treated in time,it may lead to diabetic foot ulcers or Charcot arthropathy.For the management of diabetic foot,shoe modifications and orthoses can be used to reduce pressure on the affected foot or provide the foot with increased stability.In addition,the shoe modifications and orthotic devices can relieve patient discomfort during walking.Appropriate shoe modifications include changing the insole material,modifying the heel height,adding a steel shank or rocker sole,and using in-depth shoes.Alternatively,a walking brace or ankle-foot orthosis can be used to reduce the pressure on the affected foot.The purpose of this narrative review was to provide a reference guide to support clinicians in prescribing shoe modifications and foot orthoses to treat diabetic foot ulcers and Charcot arthropathy. | Min Cheol Chang Yoo Jin Choo In Sik Park Myung Woo Park Du Hwan Kim | 2022 | World Journal of Diabetes2022，13，11： | 1 |

| 18 | Right lower limb apraxia in a patient with left supplementary motor area infarction: intactness of the corticospinal tract confirmed by transcranial magnetic stimulation显示文摘We reported a 50-year-old female patient with left supplementary motor area infarction who presented right lower limb apraxia and investigated the possible causes using transcranial magnetic stimulation. The patient was able to walk and climb stairs spontaneously without any assistance at 3 weeks after onset. However, she was unable to intentionally move her right lower limb although she understood what she supposed to do. The motor evoked potential evoked by transcranial magnetic stimulation from the right lower limb was within the normal range, indicating that the corticospinal tract innervating the right lower limb was uninjured. Thus, we thought that her motor dysfunction was not induced by motor weakness, and confirmed her symptoms as apraxia. In addition, these results also suggest that transcranial magnetic stimulation is helpful for diagnosing apraxia. | Min Cheol Chang Min Ho Chun | 2015 | Neural Regeneration Research2015，10，2： | 1 |
