| 2 | 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 |
| 3 | Long-term result of endoscopic Histoacryl (N-butyl-2-cyanoacrylate)injection for treatment of gastric varices显示文摘AIM:To evaluate the long-term efficacy and safety of endoscopic obliteration with Histoacryl for treatment of gastric variceal bleeding and prophylaxis.METHODS:Between January 1994 and March 2010 at SoonChunHyang University Hospital,a total of 127 patients with gastric varices received Histoacryl injections endoscopically.One hundred patients underwent endoscopic Histoacryl injections because of variceal bleeding,the other 27 patients received such injections as a prophylactic procedure.RESULTS:According to Sarin classification,56 patients were GOV1,61 patients were GOV2 and 10 patients were IGV.Most of the varices were large(F2 or F3,111 patients).The average volume of Histoacryl per each session was 1.7±1.3 cc and mean number of sessions was 1.3±0.6.(1 session-98 patients,2 sessions-25 patients,≥3 sessions-4 patients).Twenty-seven patients with high risk of bleeding(large or fundal or RCS+or Child C) received Histoacryl injection as a primary prophylactic procedure.In these patients,hepatitis B virus was the major etiology of cirrhosis,25 patients showed GOV1 or 2(92.6%)and F2 or F3 accounted for 88.9%(n=24).The rate of initial hemostasis was 98.4%and recurrent bleeding within one year occurred in 18.1%of patients.Successful hemostasis during episodes of rebleeding was achieved in 73.9%of cases.Median survival was 50 mo (95%CI 30.5-69.5).Major complications occurred in 4 patients(3.1%).The rebleeding rate in patients with hepatocellular carcinoma or GOV2 was higher than in those with other conditions.None of the 27 subjects who were treated prophylactically experienced treatment-related complications.Cumulative survival rates of the 127 patients at 6 mo,1,3,and 5 years were 92.1%,84.2%,64.2%,and 45.3%,respectively.The 6 mo cumulative survival rate of the 27 patients treated prophylactically was 75%.CONCLUSION:Histoacryl injection therapy is an effective treatment for gastric varices and also an effective prophylactic treatment of gastric varices which carry high risk of bleeding. | Eun Jung Kang Soung Won Jeong Jae Young Jang Joo Young Cho Sae Hwan Lee Hyun Gun Kim Sang Gyune Kim Young Seok Kim Young Koog Cheon Young Deok Cho Hong Soo Kim Boo Sung Kim | 2011 | World Journal of Gastroenterology2011,17,11: | 41 |
| 4 | Clinical implications of fatty pancreas:Correlations between fatty pancreas and metabolic syndrome显示文摘AIM:To investigate the clinical implications of lipid deposition in the pancreas(fatty pancreas). METHODS:The subjects of this study were 293 patients who had undergone abdominal computed tomography(CT)and sonography.Fatty pancreas was diagnosed by sonographic findings and subdivided into mild,moderate,and severe fatty pancreas groups comparing to the retroperitoneal fat echogenicity. RESULTS:Fatty pancreas was associated with higher levels for visceral fat,waist circumference,aspartate aminotransferase(AST),alanine aminotransferase (ALT),total cholesterol,triglyceride,high density lipoprotein,free fatty acid,γ-GTP,insulin,and the homeostasis model assessment of insulin resistance (HOMA-IR)than the control group(P<0.05).HOMAIR,visceral fat,triglyceride,and ALT also tended to increase with the degree of fat deposition in the pancreas on sonography.In a multivariate logistic regression analysis,HOMA-IR,visceral fat,and ALT level were independently related to fatty pancreas after adjustment for age,body mass index,and lipid profile.The incidence of metabolic syndrome in the fatty pancreas group was significantly higher than in the control group,and the numbers of metabolic syndrome parameters were significantly higher in the fatty pancreas group(P<0.05).CONCLUSION:Sonographic fatty pancrease showed higher insulin resistance,visceral fat area,triglyceride, and ALT levels than normal pancreases.Fatty pancreas also showed a strong correlation with metabolic syndrome. | Jun Seok Lee Sang Heum Kim Dae Won Jun Jee Hye Han Eun Chul Jang Ji Young Park Byung Kwan Son Seong Hwan Kim Yoon Ju Jo Young Sook Park Yong Soo Kim | 2009 | World Journal of Gastroenterology2009,15,15: | 40 |
| 5 | Efficacy and safety of 0.4 percent sodium hyaluronate for endoscopic submucosal dissection of gastric neoplasms显示文摘AIM:To evaluate the efficacy and safety of sodium hyaluronate solution(SH) in endoscopic submucosal dissection(ESD) of gastric neoplasms.METHODS:A prospective multicenter randomized,double blind,controlled trial was designed and utilized in this study.A total of 76 patients with 5-20 mm sized gastric neoplasms were enrolled at three academic hospitals in South Korea from June 2011 to October 2011.Patients were randomly assigned to the 0.4% sodium hyaluronate or control groups.All lesions underwent endoscopic ESD.ESD was performed with 0.4%SH and normal saline(NS) solution for submucosal injection.Efficacy was assessed using en bloc resection and the number of additional injections.Secondary evaluation variables were the volume of injection material,steepness of mucosal elevation,bleeding rate,procedural time and operator satisfaction.Finally,the safety was assessed by analyzing adverse events during the study.RESULTS:The usefulness rate in the 0.4%SH group and the controlled group had statistically significant difference under intention to treat(ITT) analysis(90.91% vs 61.11% P = 0.0041).Under per protocol(PP),the usefulness rate is statistically significant different(93.10% vs 61.76%,P = 0.0036).The difference in volume of the solution injected between 0.4%SH group and the controlled group and NS group was also statistically significant under intention to treat and per protocol analysis(ITT:0.03 ± 0.02 mL vs 0.06 ± 0.03 mL,P = 0.0003,PP:0.03 ± 0.02 mL vs 0.06 ± 0.03 mL,P = 0.0004).Satisfaction above the grade good was significantly higher in the SH group under intention to treat and per protocol analysis(ITT:90.91% vs 61.11%,P = 0.0041,PP = 93.11% vs 61.77%,P = 0.0022).Adverse events above grade 3 were not noticed in either group.All adverse events were treated and were judged as not associated with the submucosal injection solutions.CONCLUSION:0.4%SH solution is a safe and effective agent that doesn't cause any significant adverse events and is useful for submucosal injection during ESD. | Young Dae Kim Jun Lee Ju Yeon Cho Seok Won Kim Seong Hwan Kim Young Kwan Cho Jin Seok Jang Ji Sun Han Joo Young Cho | 2013 | World Journal of Gastroenterology2013,19,20: | 26 |

| 7 | Common bile duct stones on multidetector computed tomography:Attenuation patterns and detectability显示文摘AIM:To investigate the attenuation patterns and detectability of common bile duct(CBD) stones by multidetector computed tomography(MDCT).METHODS:Between March 2010 and February 2012,191 patients with suspicion of CBD stones undergoing both MDCT and endoscopic retrograde cholangiopancreatography(ERCP) were enrolled and reviewed retrospectively.The attenuation patterns of CBD stones on MDCT were classified as heavily calcified,radiopaque,less radiopaque,or undetectable.The association between the attenuation patterns of CBD stones on MDCT and stone type consisting of pure cholesterol,mixed cholesterol,brown pigment,and black pigment and the factors related to the detectability of CBD stones by MDCT were evaluated.RESULTS:MDCT showed CBD stones in 111 of 130 patients in whom the CBD stones were demonstrated by ERCP with 85.4% sensitivity.The attenuation patterns of CBD stones on MDCT were heavily calcified 34(26%),radiopaque 31(24%),less radiopaque 46(35%),and undetectable 19(15%).The radiopacity of CBD stones differed significantly according to stone type(P < 0.001).From the receiver operating characteristic curve,stone size was useful for the determination of CBD stone by MDCT(area under curve 0.779,P < 0.001) and appropriate cut-off stone size on MDCT was 5 mm.The factors related to detectability of CBD stones on MDCT were age,stone type,and stone size on multivariate analysis(P < 0.05).CONCLUSION:The radiopacity of CBD stones on MDCT differed according to stone type.Stone type and stone size were related to the detectability by MDCT,and appropriate cut-off stone size was 5 mm. | Chang Whan Kim Jae Hyuck Chang Yeon Soo Lim Tae Ho Kim In Seok Lee Sok Won Han | 2013 | World Journal of Gastroenterology2013,19,11: | 24 |
| 8 | Effects of 60 Hz electromagnetic field exposure on testiculargerm cell apoptosis in mice显示文摘Aim:To evaluate the effects of 60 Hz extremely low frequency (ELF) elelctromagnetic field (EMF) exposure on germ cell apoptosis in the testis of mice.Methods:Adult male BALB/c mice (7 weeks of age) were exposed to a 60 Hz EMF of 0.1 mT or 0.5 mT for 24 h/day.A sham-exposed group served as the control.After 8 weeks of exposure,the mice were sacrificed.Germ cell apoptosis in the testis was assessed by histopathological examination,the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay (TUNEL) and flow cytometric examination of isolated spermatogenic cells stained with 7 aminoactinomycin D (7-AAD).Results:EMF exposure did not significantly affect the body and testis weights,but significantly increased the incidence of germ cell death.The distinguishing morphological feature of EMF exposure was a decrement in the number of well organized seminiferous tubules.Quantitative analysis of TUNEL-positive germ cells showed a significantly higher apoptotic rate in the 0.5 mT exposed mice than that in the sham controls (P<0.05),while the difference between the two exposed groups was insignificant.The TUNEL-positive cells were mainly spermatogonia.In flow cytometryanalysis,the percentage of live cells [forward scatter count (FSC)^hgh7-AAD-] was lower in the exposed groups than that in the controls (Figure 5A),but the decrease in viability was not statistically significant.Conclusion:Continuousexposure to ELF EMF may induce testicular germ cell apoptosis in mice.(Asian J Androl 2004 Mar;6:29-34) | Jin Sang Lee Sang Seok Ahn Kyeong Cheon Jung Yoon-Won Kim Sang Kon Lee | 2004 | Asian Journal of Andrology2004,6,1: | 23 |
| 9 | Primary endoscopic approximation suture under cap-assisted endoscopy of an ERCP-induced duodenal perforation显示文摘Duodenal perforation during endoscopic retrograde cholangiopancreatography(ERCP) is a rare complication,but it has a relatively high mortality risk.Early diagnosis and prompt management are key factors for the successful treatment of ERCP-related perforation.The management of perforation can initially be conservative in cases resulting from sphincterotomy or guide wire trauma.However,the current standard treatment for duodenal free wall perforation is surgical repair.Recently,several case reports of endoscopic closure techniques using endoclips,endoloops,or fully covered metal stents have been described.We describe four cases of iatrogenic duodenal bulb or lateral wall perforation caused by the scope tip that occurred during ERCP in tertiary referral centers.All the cases were simply managed by endoclips under transparent capassisted endoscopy.Based on the available evidence and our experience,endoscopic closure was a safe and feasible method even for duodenoscope-induced perforations.Our results suggest that endoscopists may be more willing to use this treatment. | Tae Hoon Lee Byoung Wook Bang Jee In Jeong Hyung Gil Kim Seok Jeong Seon Mee Park Don Haeng Lee Sang-Heum Park Sun-Joo Kim | 2010 | World Journal of Gastroenterology2010,16,18: | 19 |
| 10 | Eosinophilic gastroenteritis presenting as small bowel obstruction: A case report and review of the literature显示文摘Eosinophilic gastroenteritis is a rare disease of unknown etiology. It is characterized by eosinophilic infiltration of the bowel wall to a variable depth and symptoms associated with gastrointestinal tract. Recently, the authors experienced a case of eosinophilic gastroenteritis presenting as small bowel obstruction. A 51-year old woman was admitted to our hospital complaining of abdominal pain and vomiting. Physical examination revealed a distended abdomen with diffuse tenderness. Complete blood count showed mild leukocytosis without eosinophilia. Computed tomography confirmed a dilatation of the small intestine with ascites. An emergency laparotomy was performed for a diagnosis of peritonitis due to intestinal obstruction. Segmental resection of the ileum and end to end anastomosis were performed. Histologically, there was a dense infiltration of eosinophils throughout the entire thickness of ileal wall and eosinophilic enteritis was diagnosed. The patient recovered well, and was free from gastrointestinal symptoms at the time when we reported her disease. | Min Young Yun Young Up Cho In Suh Park Sun Keun Choi Sei Joong Kim Seok Hwan Shin Kyung Rae Kim | 2007 | World Journal of Gastroenterology2007,13,11: | 19 |
| 11 | Treatment strategies using adefovir dipivoxil for individuals with lamivudine-resistant chronic hepatitis B显示文摘AIM:To investigate retrospectively the long-term efficacy of various treatment strategies using adefovir dipivoxil(adefovir) in patients with lamivudine-resistant chronic hepatitis B.METHODS:We included 154 consecutive patients in two treatment groups:the 'add-on' group(n = 79),in which adefovir was added to ongoing lamivudine treatment due to lamivudine resistance,and the 'switch/combination' group(n = 75),in which lamivudine was first switched to adefovir and then re-added later as needed.The 'switch/combination' group was then divided into two subgroups depending on whether participants followed(group A,n = 30) or violated(group B,n = 45) a proposed treatment strategy that determined whether to add lamivudine based on the serum hepatitis B virus(HBV) DNA levels(< 60 IU/mL or not) after 6 mo of treatment(roadmap concept).RESULTS:The cumulative probability of virologic response(HBV DNA < 60 IU/mL) was higher in group A than in the 'add-on' group and in group B(P < 0.001).In contrast,the cumulative probability of virologic breakthrough was lower in the 'add-on' group than in group B(P = 0.002).Furthermore,the risk of virologic breakthrough in the multivariate analysis was significantly lower in the 'add-on' group than in group A(hazard ratio = 0.096;95%CI,0.015-0.629;P = 0.015).CONCLUSION:The selective combination of adefovir with lamivudine based upon early treatment responses increased the odds of virologic breakthrough relative to the use of uniform combination therapy from the beginning of treatment. | Tae Jung Yun Jin Yong Jung Chang Ha Kim Soon Ho Um Hyonggin An Yeon Seok Seo Jin Dong Kim Hyung Joon Yim Bora Keum Yong Sik Kim Yoon Tae Jeen Hong Sik Lee Hoon Jai Chun Chang Duck Kim Ho Sang Ryu | 2012 | World Journal of Gastroenterology2012,18,47: | 19 |
| 12 | Aerobic exercise improves gastrointestinal motility in psychiatric inpatients显示文摘AIM:To evaluate the benefit of aerobic exercise on colonic transit time(CTT)for psychiatric inpatients in a closed ward.METHODS:Sixty consecutive adult inpatients of the Somang Hospital Psychiatry Unit(Eumsung-gun,South Korea),without CTT-related diseases or drug therapies,were recruited for study from March to June of 2012.Upon enrollment,the patients were randomly assigned to partake in a 12-wk instructor-led group aerobic exercise program(exercise group;n=30)or to maintain their ordinary daily activities(control group;n=30).The exercise program was structured as 10 min warm-up(stretching),40 min exercise,and 10 min cool-down(stretching)for three days each week.The exercise sessions consisted of walking only in week one and aerobics from weeks two to 12,with increasing intensity(50%heart rate reserve(HRR)for weeks one to four,60%HRR for weeks five to eight,and 70%HRR for weeks nine to 12).CTT was measured before(baseline)and after(week 12)the exercise program,in duplicate(on days four and seven),using abdominal radiography and the multiple radio-opaque marker technique.Changes in the exercising patients’CTT and weight-,cardiovascular-and fitness-related parameters were statistically assessed.RESULTS:The study dropout rate was 30.0%,with 23patients in the exercise group and 19 patients in the control group completing the study.At week 12,the exercise group showed decreases in body weight(mean±SE)baseline:69.4±2.8 vs study-end:67.6±2.7;P<0.635)and body mass index(BMI)(25.2±1.1 vs24.9±0.8;P<0.810),but the extent of change was not significantly different from that experienced by the control group(body weight:68.8±4.0 vs 68.8±3.9;BMI:24.3±1.1 vs 24.4±1.2).However,the exercise group showed significant improvements in leg muscle strength(baseline:41.7±4.3 vs study-end:64.1±5.0;P<0.001),cardio-respiratory endurance(120.5±4.5vs 105.4±2.8;P<0.004),and leg muscle elasticity and power output(21.5±2.6 vs 30.6±2.8;P<0.001).The exercise group showed an exercise-induced reduction in total CTT(baseline:54.2±8.0 vs 30.3±6.1),which was significantly different from that experienced by the control group over the 12-wk period(48.6±9.3vs 48.3±12.3;P=0.027);however,the exercise-induced decreases in CTT involving the three colonic segments examined(right,left and recto-sigmoid)showed no significant differences from the control group.CONCLUSION:A 12-wk aerobic exercise program can benefit psychiatric inpatients by increasing intestinal motility,possibly decreasing risk of metabolic-and cardiovascular-related disease. | Yeon Soo Kim Bong Kil Song Ji Sun Oh Seung Seok Woo | 2014 | World Journal of Gastroenterology2014,20,30: | 19 |
| 13 | Anemia after gastrectomy for early gastric cancer:Long-term follow-up observational study显示文摘AIM:To identify the incidence and etiology of anemia after gastrectomy in patients with long-term follow-up after gastrectomy for early gastric cancer.METHODS:The medical records of those patients with early gastric adenocarcinoma who underwent curative gastrectomy between January 2006 and October 2007 were reviewed.Patients with anemia in the preoperative workup,cancer recurrence,undergoing systemic chemotherapy,with other medical conditions that can cause anemia,or treated during follow up with red cell transfusions or supplements for anemia were excluded.Anemia was defined by World Health Organization criteria(Hb < 12 g/dL in women and < 13 g/dL in men).Iron deficiency was defined as serum ferritin < 20 g/dL.Vitamin B12 deficiency was defined as serum vitamin B 12 < 200 pg/mL.Iron deficiency anemia was defined as anemia with concomitant iron deficiency.Anemia from vitamin B 12 deficiency was defined as megaloblastic anemia(mean cell volume > 100 fL) with vitamin B 12 deficiency.The profile of anemia over 48 mo of follow-up was analyzed.RESULTS:One hundred sixty-one patients with gastrectomy for early gastric cancer were analyzed.The incidence of anemia was 24.5% at 3 mo after surgery and increased up to 37.1% at 48 mo after surgery.The incidence of iron deficiency anemia increased during the follow up and became the major cause of anemia at 48 mo after surgery.Anemia of chronic disease and megaloblastic anemia were uncommon.The incidence of anemia in female patients was significantly higher than in male patients at 12(40.0% vs 22.0%,P = 0.033),24(45.0% vs 25.0%,P = 0.023),36(55.0% vs 28.0%,P = 0.004),and 48 mo(52.0% vs 31.0%,P = 0.022) after surgery.Patients with total gastrectomy showed significantly higher incidence of anemia than patients with subtotal gastrectomy at 48 mo after surgery(60.7% vs 31.3%,P = 0.008).The incidence of iron deficiency was significantly higher in female patients than in male patients at 6(35.4% vs 13.3%,P = 0.002),12(45.8% vs 16.8%,P < 0.001),18(52.1% vs 22.3%,P < 0.001),24(60.4% vs 20.9%,P < 0.001),36(62.5% vs 29.2%,P < 0.001),and 48 mo(66.7% vs 34.7%,P = 0.001) after surgery.CONCLUSION:Anemia was frequent after gastrectomy for early gastric cancer,with iron deficiency being the major cause.Evaluation for anemia including iron status should be performed after gastrectomy and appropriate iron replacement should be considered. | Chul-Hyun Lim Sang Woo Kim Won Chul Kim Jin Soo Kim Yu Kyung Cho Jae Myung Park In Seok Lee Myung-Gyu Choi Kyo-Young Song Hae Myung Jeon Cho-Hyun Park | 2012 | World Journal of Gastroenterology2012,18,42: | 18 |
| 14 | Proton pump inhibitor administration delays rebleeding after endoscopic gastric variceal obturation显示文摘AIM:To clarify the efficacy of proton pump inhibitors(PPIs)after endoscopic variceal obturation(EVO)with N-butyl-2-cyanoacrylate.METHODS:A retrospective study was performed on16 liver cirrhosis patients with gastric variceal bleeding that received EVO with injections of N-butyl-2-cyanoacrylate at a single center(Kyung Hee University Hospital at Gangdong)from January 2008 to December 2012.Medical records including patient characteristics and endoscopic findings were reviewed.Treatment results,liver function,serum biochemistry and cirrhosis etiology were compared between patients receiving PPIs and those that did not.Furthermore,the rebleeding interval was compared between patients that received PPI treatment after EVO and those who did not.RESULTS:The patient group included nine males and seven females with a mean age of 61.8±11.7years.Following the EVO procedure,eight of the 12patients that received PPIs and three of the four nonPPI patients experienced rebleeding.There were no differences between the groups in serum biochemistry or patient characteristics.The rebleeding rate was not significantly different between the groups,however,patients receiving PPIs had a significantly longer rebleeding interval compared to non-PPI patients(22.2±11.2mo vs 8.5±5.5 mo;P=0.008).The duration of PPI use was not related to the rebleeding interval.A total of six patients,who had ulcers at the injection site,exhibited a shorter rebleeding interval(16.8±5.9 mo)than patients without ulcers(19.9±3.2 mo),though this difference was not statistically significant.CONCLUSION:PPI therapy can extend the rebleeding interval,and should therefore be considered after EVO treatment for gastric varices. | Won Seok Jang Hyun Phil Shin Joung Ⅱ Lee Kwang Ro Joo Jae Myung Cha Jung Won Jeon Jun Uk Lim | 2014 | World Journal of Gastroenterology2014,20,45: | 17 |
| 15 | Central post-stroke pain due to injury of the spinothalamic tract in patients with cerebral infarction: a diffusion tensor tractography imaging study显示文摘Many studies using diffusion tensor tractography(DTT) have demonstrated that injury of the spinothalamic tract(STT) is the pathogenetic mechanism of central post-stroke pain(CPSP) in intracerebral hemorrhage; however, there is no DTT study reporting the pathogenetic mechanism of CPSP in cerebral infarction. In this study, we investigated injury of the STT in patients with CPSP following cerebral infarction, using DTT. Five patients with CPSP following cerebral infarction and eight age-and sex-matched healthy control subjects were recruited for this study. STT was examined using DTT. Among DTT parameters of the affected STT, fractional anisotropy and tract volume were decreased by more than two standard deviations in two patients(patients 1 and 2) and three patients(patients 3, 4, and 5), respectively, compared with those of the control subjects, while mean diffusivity value was increased by more than two standard deviations in one patient(patient 2). Regarding DTT configuration, all affected STTs passed through adjacent part of the infarct and three STTs showed narrowing. These findings suggest that injury of the STT might be a pathogenetic etiology of CPSP in patients with cerebral infarction. | Sung Ho Jang Jun Lee Sang Seok Yeo | 2017 | Neural Regeneration Research2017,12,12: | 17 |
| 16 | Effect of an Artificial Caudal Fin on the Performance of a Biomimetic Fish Robot Propelled by Piezoelectric Actuators显示文摘This paper addresses the design of a biomimetic fish robot actuated by piezoceramic actuators and the effect of artificial caudal fins on the fish robot's performance. The limited bending displacement produced by a lightweight piezocomposite actuator was amplified and transformed into a large tail beat motion by means of a linkage system. Caudal fins that mimic the shape of a mackerel fin were fabricated for the purpose of examining the effect of caudal fin characteristics on thrust pro-duction at an operating frequency range. The thickness distribution of a real mackerel's fin was measured and used to design artificial caudal fins. The thrust performance of the biomimetic fish robot propelled by fins of various thicknesses was examined in terms of the Strouhal number,the Froude number,the Reynolds number,and the power consumption.

| 17 | Tenofovir rescue therapy for chronic hepatitis B patients after multiple treatment failures显示文摘AIM:To evaluate the efficacy and safety of tenofovir disoproxil fumarate(TDF) for chronic hepatitis B(CHB) patients after multiple failures.METHODS:A total of 29 CHB patients who had a suboptimal response or developed resistance to two or more previous nucleoside/nucleotide analogue(NA) treatments were included.Study subjects were treated with TDF alone(n = 13) or in combination with lamivudine(LAM,n = 12) or entecavir(ETV,n = 4) for ≥ 6 mo.Complete virologic response(CVR) was defined as an achievement of serum hepatitis B virus(HBV) DNA level ≤ 60 IU/mL by real-time polymerase chain reaction method during treatment.Safety assessment was based on serum creatinine and phosphorus level.Eleven patients had histories of LAM and adefovir dipivoxil(ADV) treatment and 18 patients were exposed to LAM,ADV,and ETV.Twenty-seven patients(93.1%) were hepatitis B e antigen(HBeAg) positive and the mean value of the baseline serum HBV DNA level was 5.5 log IU/mL ± 1.7 log IU/mL.The median treatment duration was 16 mo(range 7 to 29 mo).RESULTS:All the patients had been treated with LAM and developed genotypic and phenotypic resistance to it.Resistance to ADV was present in 7 patients and 10 subjects had a resistance to ETV.One patient had a resistance to both ADV and ETV.The cumulative probabilities of CVR at 12 and 24 mo of TDF containing treatment regimen calculated by the Kaplan Meier method were 86.2% and 96.6%,respectively.Although one patient failed to achieve CVR,serum HBV DNA level decreased by 3.9 log IU/mL from the baseline and the last serum HBV DNA level during treatment was 85 IU/mL,achieving near CVR.No patients in this study showed viral breakthrough or primary non-response during the follow-up period.The cumulative probability of HBeAg clearance in the 27 HBeAg positive patients was 7.4%,12%,and 27% at 6,12,and 18 mo of treatment,respectively.Treatment efficacy of TDF containing regimen was not statistically different according to the presence of specific HBV mutations.History of prior exposure to specific antiviral agents did not make a difference to treatment outcome.Treatment efficacy of TDF was not affected by combination therapy with LAM or ETV.No patient developed renal toxicity and no cases of hypophosphatemia associated with TDF therapy were observed.There were no other adverse events related to TDF therapy observed in the study subjects.CONCLUSION:TDF can be an effective and safe rescue therapy in CHB patients after multiple NA therapy failures. | Yu Jin Kim Dong Hyun Sinn Geum-Youn Gwak Moon Seok Choi Kwang Cheol Koh Seung Woon Paik Byung Chul Yoo Joon Hyeok Lee | 2012 | World Journal of Gastroenterology2012,18,47: | 16 |
| 18 | Gastric cancer patients at high-risk of having synchronous cancer显示文摘瞄准:识别病人与一在胃的癌症病人之中有同步癌症高风险。方法:我们回顾地在国家癌症中心分析了未来的胃的癌症数据库,从 2000 年 12 月的朝鲜到 2004 年 12 月。有没有同步癌症的病人的同步癌症和那些的病人的 clinicopathological 特征被比较。Multivariate 分析被执行在胃的癌症病人为同步癌症的存在识别风险因素。结果:在数据库登记的 3291 个胃的癌症病人(3.4%) 中的 111 个有同步癌症。在这 111 个病人之中, 109 有单个同步癌症, 2 个病人有二同步癌症。同步癌症的最普通的形式是颜色表面的癌症(42 个病人, 37.2%) 由肺癌症列在后面(21 个病人, 18.6%) 。Multivariate 分析表明有区分的早胃的癌症的老病人有同步癌症的更高的可能性。结论:在胃的癌症病人的同步癌症不是很少发生的。医生应该试着在胃的癌症病人发现同步癌症,在特别与区分的早胃的癌症老。 | Jun Ho Lee Ja Seong Bae Keun Won Ryu Jong Seok Lee Sook Ryun Park Chan Gyoo Kim Myoung Cheorl Kook Il Ju Choi Young Woo Kim Jae-Gahb Park Jae-Moon Bae | 2006 | World Journal of Gastroenterology2006,12,16: | 15 |
| 19 | Does the bile duct angulation affect recurrence of choledocholithiasis?显示文摘AIM:To investigate whether bile duct angulation and T-tube choledochostomy influence the recurrence of choledocholithiasis.METHODS:We conducted a retrospective study including 259 patients who underwent endoscopic sphincterotomy and cholecystectomy for choledocholithiasis between 2000 and 2007.The imaginary line was drawn along the center of the bile duct and each internal angle was measured at the two angulation sites ofthe bile duct respectively.The values of both angles were added together.We then tested our hypothesis by examining whether T-tube choledochostomy was performed and stone recurrence occurred by reviewing each subject's medical records.RESULTS:The overall recurrence rate was 9.3% (24 of 259 patients).The mean value of sums of angles in the recurrence group was 268.3°± 29.6°,while that in the non-recurrence group was 314.8°± 19.9° (P < 0.05).Recurrence rate of the T-tube group was 15.9% (17 of 107),while that of the non T-tube group was 4.6% (7 of 152) (P < 0.05).Mean value of sums of angles after T-tube drainage was 262.5°± 24.6° and that before T-tube drainage was 298.0°± 23.9° in 22 patients (P < 0.05).CONCLUSION:The bile duct angulation and T-tube choledochostomy may be risk factors of recurrence of bile duct stones. | Dong Beom Seo Byoung Wook Bang Seok Jeong Don Haeng Lee Shin Goo Park Yong Sun Jeon Jung Il Lee Jin-Woo Lee | 2011 | World Journal of Gastroenterology2011,17,36: | 15 |
