| 1 | Expression of heat shock proteins (HSP27, HSP60, HSP70, HSP90, GRP78, GRP94) in hepatitis B virus-related hepatocellular carcinomas and dysplastic nodules显示文摘AIM: Expression of heat shock proteins (HSPs) is frequently up-regulated in hepatocellular carcinoma (HCC), which evolves from dysplastic nodule (DN) and early HCC to advanced HCC. However, little is known about the differential expression of HSPs in multistep hepatocarcinogenesis. It was the purpose of this study to monitor the expression of HSPs in multistep hepatocarcinogenesis and to evaluate their prognostic significance in hepatitis B virus (HBV)related HCC.METHODS: Thirty-eight HCC and 19 DN samples were obtained from 52 hepatitis B surface antigen-positive Korean patients. Immunohistochemical and dot immunoblot analyses of HSP27, HSP60, HSP70, HSP90, glucoseregulated protein (GRP)78, and GRP94 were performed and their expression at different stages of HCC development was statistically analyzed.RESULTS: Expression of HSP27, HSP70, HSP90, GRP78, and GRP94 increased along with the stepwise progression of hepatocarcinogenesis. Strong correlation was found only in GRP78 (Spearman's r= 0.802). There was a positive correlation between the expressions of GRP78, GRP94, HSP90, or HSP70 and prognostic factors of HCC. Specifically, the expression of GRP78, GRP94, or HSP90 was associated significantly with vascular invasion and intrahepatic metastasis.CONCLUSION: The expressions of HSPs are commonly up-regulated in HBV-related HCCs and GRP78 might play an important role in the stepwise progression of HBVrelated hepatocarcinogenesis. GRP78, GRP94, and HSP90 may be important prognostic markers of HBV-related HCC, strongly suggesting vascular invasion and intrahepatic metastasis. | Seung Oe Lim Sung Gyoo Park Jun-Hi Yoo Young Min Park Hie-Joon Kim Kee-Taek Jang Jae Won Cho Byung Chul Yoo Gu-Hung Jung Cheol Keun Park | 2005 | World Journal of Gastroenterology2005，11，14： | 62 |

| 3 | Clinical epidemiology and disease burden of nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) is defined as the presence of hepatic fat accumulation after the exclusion of other causes of hepatic steatosis, including other causes of liver disease, excessive alcohol consumption, and other conditions that may lead to hepatic steatosis. NAFLD encompasses a broad clinical spectrum ranging from nonalcoholic fatty liver to nonalcoholic steatohepatitis(NASH), advanced fibrosis, cirrhosis, and finally hepatocellular carcinoma(HCC). NAFLD is the most common liver disease in the world and NASH may soon become the most common indication for liver transplantation. Ongoing persistence of obesity with increasing rate of diabetes will increase the prevalence of NAFLD, and as this population ages, many will develop cirrhosis and end-stage liver disease. There has been a general increase in the prevalence of NAFLD, with Asia leading the rise, yet the United States is following closely behind with a rising prevalence from 15% in 2005 to 25% within 5 years. NAFLD is commonly associated with metabolic comorbidities, including obesity, type Ⅱ diabetes, dyslipidemia, and metabolic syndrome. Our understanding of the pathophysiology of NAFLD is constantly evolving. Based on NAFLD subtypes, it has the potential to progress into advanced fibrosis, end-stage liver disease and HCC. The increasing prevalence of NAFLD with advanced fibrosis, is concerning because patients appear toexperience higher liver-related and non-liver-related mortality than the general population. The increased morbidity and mortality, healthcare costs and declining health related quality of life associated with NAFLD makes it a formidable disease, and one that requires more in-depth analysis. | Brandon J Perumpail Muhammad Ali Khan Eric R Yoo George Cholankeril Donghee Kim Aijaz Ahmed | 2017 | World Journal of Gastroenterology2017，23，47： | 70 |

| 5 | Overexpression of S100A4 is closely associated with progression of colorectal cancer显示文摘AIM: To investigate whether S100A4 played an important role in the development or progression of colorectal cancer.METHODS: A total of 124 colorectal adenocarcinoma tissue specimens were analyzed by immunohistochemistry for the expression of S100A4 protein and subsequently investigated for the gene mutations in the coding region of S100A4 gene. The specimens were collected over a 3-year period in the laboratories at our large teaching hospital in Seoul, Republic of Korea.RESULTS: Normal colonic epithelium either failed to express or showed focal weak expression of S100A4. Moderate to strong cytoplasmic expression of S100A4 was seen in 69(55.6%) of the 124 colorectal carcinoma tissue specimens.S100A4 expression was detected in 43 (69.4%) of 62specimens with lymph node metastasis. Statistically,overexpression of S100A4 was significantly associated with Dukes' stage and lymph node metastasis. Nuclear staining was also observed in 24 (19.4%) of 124 samples and closely associated with Dukes' stage. However, there was no significant correlation between overexpression of S100A4and other investigated clinico-pathologic parameters,including tumor localization, tumor size, and survival period.In mutational analysis, no gene mutation was found in the analyzed genomic area of colorectal cancer.CONCLUSION: Overexpression of 5100A4 may be closely related with the aggressiveness of colorectal carcinoma. | Yong-Gu Cho Chang-Jae Kim Suk-Woo Nam Shin-Hee Yoon Sug-Hyung Lee Nam-Jin Yoo Jung-Young Lee Won-Sang Park | 2005 | World Journal of Gastroenterology2005，11，31： | 40 |
| 6 | Effects of Cordyceps militaris extract on angiogenesis and tumor growth显示文摘AIM: To evaluate the effects of Cordyceps militaris extract (CME) on angiogenesis and tumor growth. METHODS:Human umbilical vein endothelial cells (HUVEC), HT1080, and B16-F10 cells were used. DNA fragment, angio-genic related gene expressions (MMPs, bFGF, VEGF, etc), capillary tube formation, wound healing in vitro, tumorgrowth in vivo were measured. RESULTS: CME inhibited growth of HUVECs and HT1080 (P<0.01). CME 100and 200 mg/L reduced MMP-2 gene expression in HT1080 cells by 6.0 % and 22.9 % after 3-h and 14.9 % and32.8 % after 6-h treatment. CME did not affect MMP-9 gene expression in B16-F10 melanoma cells. CME 100 and200 mg/L also reduced bFGF gene expression in HUVECs by 22.2 % and 41.3 %. CME inhibited tube formation ofendothelial cells in vitro and in vivo. CME repressed the growth of B16-F10 melanoma cells in mice compared withcontrol group (P<0.05). CONCLUSION: CME has antiangiogenetic properties. | Hwa-seung YOO Jang-woo SHIN Jung-hyo CHO Chang-gue SON Yeon-weol LEE Sang-yong PARK Chong-kwan CHO | 2004 | Acta Pharmacologica Sinica2004，25，5： | 40 |
| 7 | Irritable bowel syndrome:Emerging paradigm in pathophysiology显示文摘Irritable bowel syndrome(IBS)is one of the most common gastrointestinal disorders,characterized by abdominal pain,bloating,and changes in bowel habits.These symptoms cannot be explained by structural abnormalities and there is no specific laboratory test or biomarker for IBS.Therefore,IBS is classified as a functional disorder with diagnosis dependent on the history taking about manifested symptoms and careful physical examination.Although a great deal of research has been carried out in this area,the pathophysiology of IBS is complex and not completely understood.Multiple factors are thought to contribute to the symptoms in IBS patients;altered gastrointestinal motility,visceral hypersensitivity,and the brain-gut interaction are important classical concepts in IBS pathophysiology.New areas of research in this arena include inflammation,postinfectious low-grade inflammation,genetic and immunologic factors,an altered microbiota,dietary factors,and enteroendocrine cells.These emerging studies have not shown consistent results,provoking controversy in the IBS field.However,certain lines of evidence suggest that these mechanisms are important at least a subset of IBS patients,confirming that IBS symptoms cannot be explained by a single etiological mechanism.Therefore,it is important to keep in mind that IBS requires a more holistic approach to determining effective treatment and understanding the underlying mechanisms. | Yoo Jin Lee Kyung Sik Park | 2014 | World Journal of Gastroenterology2014，20，10： | 27 |
| 8 | Double guidewire technique vs transpancreatic precut sphincterotomy in difficult biliary cannulation显示文摘AIM:To compare the outcomes between doubleguidewire technique(DGT) and transpancreatic precut sphincterotomy(TPS) in patients with difficult biliary cannulation.METHODS:This was a prospective,randomized study conducted in single tertiary referral hospital in Korea.Between January 2005 and September 2010.A total of 71 patients,who bile duct cannulation was not possible and selective pancreatic duct cannulation was achieved,were randomized into DGT(n = 34) and TPS(n = 37) groups.DGT or TPS was done for selective biliary cannulation.We measured the technical success rates of biliary cannulation,median cannulation time,and procedure related complications.RESULTS:The distribution of patients after randomization was balanced,and both groups were comparable in baseline characteristics,except the higher percentage of endoscopic nasobiliary drainage in the DGT group(55.9% vs 13.5%,P < 0.001).Successful cannulation rate and mean cannulation times in DGT and TPS groups were 91.2% vs 91.9% and 14.1 ± 13.2 min vs 15.4 ± 17.9 min,P = 0.732,respectively.There was no significant difference between the two groups.The overall incidence of post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis was 38.2% vs 10.8%,P < 0.011 in the DGT group and the TPS group;post-procedure pancreatitis was significantly higher in the DGT group.But the overall incidence of post-ERCP hyperamylasemia was no significant difference between the two groups;DGT group vs TPS group:14.7% vs 16.2%,P < 1.0.CONCLUSION:When free bile duct cannulation was difficult and selective pancreatic duct cannulation was achieved,DGT and TPS facilitated biliary cannulation and showed similar success rates.However,post-procedure pancreatitis was significantly higher in the DGT group. | Young Wook Yoo Sang-Woo Cha Woong Cheul Lee Sae Hee Kim Anna Kim Young Deok Cho | 2013 | World Journal of Gastroenterology2013，19，1： | 25 |
| 9 | Glycyrrhizin attenuates HMGB1-induced hepatocyte apoptosis by inhibiting the p38-dependent mitochondrial pathway显示文摘AIM:To examine how high-mobility group box 1 (HMGB1) regulates hepatocyte apoptosis and,furthermore,to determine whether glycyrrhizin (GL),a known HMGB1 inhibitor,prevents HMGB1-induced hepatocyte apoptosis.METHODS:A human hepatocellular carcinoma cell line stably transfected with a bile acid transporter (HuhBAT cells),were used in this study.Apoptosis was quantified using 4',6-diamidino-2-phenylindole dihydrochloride staining and the APO Percentage apoptosis assay,and its signaling cascades were explored by immunoblot analysis.Kinase signaling was evaluated by immunoblotting and by using selective inhibitors.It is also tried to identify hepatocyte apoptosis affected by the HMGB1 inhibitor,GL.RESULTS:HMGB1 increased cellular apoptosis in HuhBAT cells.HMGB1 led to increased cytochrome c release from mitochondria into the cytosol,and induced the cleavage of procaspase 3.However,it did not affect the activation of caspase 8.HMGB1-induced caspase 3 activation was significantly attenuated by the p38 inhibitor SB203580.GL significantly attenuated HMGB1-induced hepatocyte apoptosis.GL also prevented HMGB1-induced cytochrome c release and p38 activation in Huh-BAT cells.CONCLUSION:The present study demonstrated that HMGB1 promoted hepatocyte apoptosis through a p38dependent mitochondrial pathway.In addition,GL had an anti-apoptotic effect on HMGB1-treated hepatocytes. | Geum-Youn Gwak Tae Gun Moon Dong Ho Lee Byung Chul Yoo | 2012 | World Journal of Gastroenterology2012，18，7： | 26 |
| 10 | Comparison of the efficacy and safety of sedation between dexmedetomidine-remifentanil and propofol-remifentanil during endoscopic submucosal dissection显示文摘AIM: To compare the efficacy and safety of sedation protocols for endoscopic submucosal dissection(ESD) between dexmedetomidine-remifentanil and propofolremifentanil.METHODS: Fifty-nine patients scheduled for ESD were randomly allocated into a dexmedetomidineremifentanil(DR) group or a propofol-remifentanil(PR) group. To control patient anxiety, dexmedetomidine or propofol was infused to maintain a score of 4-5 on the Modified Observer's Assessment of Alertness/Sedation scale. Remifentanil was infused continuously at a rate of 6 μg/kg per hour in both groups. The ease of advancing the scope into the throat, gastric motility grading, and satisfaction of the endoscopist and patient were assessed. Hemodynamic variables and hypoxemic events were compared to evaluate patient safety.RESULTS: Demographic data were comparable between the groups. The hemodynamic variables and pulse oximetry values were stable during the procedure in both groups despite a lower heart rate in the DR group. No oxygen desaturation events occurred in either group. Although advancing the scope into the throat was easier in the PR group('very easy' 24.1% vs 56.7%, P = 0.010), gastric motility was moresuppressed in the DR group('no + mild' 96.6% vs 73.3%, P = 0.013). The endoscopists felt that the procedure was more favorable in the DR group('very good + good' 100% vs 86.7%, P = 0.042), whereas patient satisfaction scores were comparable between the groups. En bloc resection was performed 100% of the time in both groups, and the complete resection rate was 94.4% in the DR group and 100% in the PR group(P = 0.477). CONCLUSION: The efficacy and safety of dexmedetomidine and remifentanil were comparable to propofol and remifentanil during ESD. However, the endoscopists favored dexmedetomidine perhaps due to lower gastric motility. | Namo Kim Young-Chul Yoo Sang Kil Lee Hyunzu Kim Hyang Mi Ju Kyeong Tae Min | 2015 | World Journal of Gastroenterology2015，21，12： | 25 |

| 12 | Laser cleaning of steel structure surface for paint removal and repaint adhesion显示文摘Paint removal from steel structure is executed for shipyards of marine and offshore engineering.Due to environmental unfriendliness and unhealthy drawbacks of sand blasting technique, laser ablation technique is proposed as a substituting method.By absorbing high energy of the 1064 nm pulsed laser, the paint is vaporized quickly.The ablated debris is then collected by using a suction pump.Initial metal surface of the steel is exposed when laser beam irradiates perpendicularly and scans over it.The cleaned surface fulfills the requirements of surface preparation standards ISO 8501 of SA2.The adhesion is further characterized with pull-off test after carrying out painting with Jotamastic 87 aluminum paint.The repainting can be embedded onto the laser cleaned surface to bond much more tightly.The excellent adhesion strength of 20 MPa between repainted coating and the substrate is achieved, which is higher than what is required by shipyards applications. | Xiaoguang Li Tingting Huang Ang Wei Chong Rui Zhou Yoo Sang Choo Minghui Hong | 2017 | 光电工程2017，44，3： | 24 |
| 13 | 高速旋转电弧传感器的数学模型显示文摘以气保护焊接系统的数学模型和HALMOY焊丝熔化模型为基础,对高速旋转电弧传感器进行数学建模。利用该数学模型模拟焊接电流、弧长和焊丝伸出长度随时间的变化规律。实际焊接试验显示,模拟焊接电流与实际焊接电流波形高度吻合,说明建立的数学模型是准确的。结果表明,高速旋转电弧焊接时,弧长的变化较焊丝伸出长度的变化更为显著。利用每个电弧旋转周期内左半周与右半周平均电流值的差,可以判断焊枪的偏差量及其方向,同时还可根据平均电流值的大小来检测角接终止点。所建立的模型对于高速旋转电弧传感系统的设计具有指导意义。 | 石永华 王国荣 YOO Won-Sang NA Suck-Joo | 2007 | 机械工程学报2007，43，11： | 22 |

| 15 | Real time shear wave elastography in chronic liver diseases:Accuracy for predicting liver fibrosis,in comparison with serum markers显示文摘AIM:To evaluate the correlation between liver stiffness measurement(LSM)by real-time shear wave elastography(SWE)and liver fibrosis stage and the accuracy of LSM for predicting significant and advanced fibrosis,in comparison with serum markers.METHODS:We consecutively analyzed 70 patients with various chronic liver diseases.Liver fibrosis was staged from F0 to F4 according to the Batts and Ludwig scoring system.Significant and advanced fibrosis was defined as stage F≥2 and F≥3,respectively.The accuracy of prediction for fibrosis was analyzed using receiver operating characteristic curves.RESULTS:Seventy patients,15 were belonged to F0-F1 stage,20 F2,13 F3 and 22 F4.LSM was increased with progression of fibrosis stage(F0-F1:6.77±1.72,F2:9.98±3.99,F3:15.80±7.73,and F4:22.09±10.09,P<0.001).Diagnostic accuracies of LSM for prediction of F≥2 and F≥3 were 0.915(95%CI:0.824-0.968,P<0.001)and 0.913(95%CI:0.821-0.967,P<0.001),respectively.The cut-off values of LSM for prediction of F≥2 and F≥3 were 8.6kPa with 78.2%sensitivity and 93.3%specificity and10.46 kPa with 88.6%sensitivity and 80.0%specificity,respectively.However,there were no significant differences between LSM and serum hyaluronic acid and typeⅣcollagen in diagnostic accuracy.CONCLUSION:SWE showed a significant correlation with the severity of liver fibrosis and was useful and accurate to predict significant and advanced fibrosis,comparable with serum markers. | Jae Yoon Jeong Tae Yeob Kim Joo Hyun Sohn Yongsoo Kim Woo Kyoung Jeong Young-Ha Oh Kyo-Sang Yoo | 2014 | World Journal of Gastroenterology2014，20，38： | 19 |
| 16 | 隧道复合式防排水系统的设计、试验及工程应用显示文摘传统隧道防排水系统中,防水板极易因施工控制不当出现破裂,而防水板破裂后,地下水进入防水板与二衬间的空隙中,由于防水板与二衬间缺乏排水通道,地下水将沿衬砌裂缝、施工缝等薄弱环节渗出而形成隧道渗漏水病害。在传统隧道防排水系统中,渗漏水病害治理难度大,维修费用高,针对传统防排水系统存在的不足,提出了一种在隧道防水板与二衬间增设排水板的复合式防排水系统,该系统具有可调节、抗淤堵、易维护等优点。为验证该系统的有效性,采用自主研制的试验装置对复合式防排水系统中所采用的3种土工排水材料(毛细型排水板、凸壳型排水板、土工布)在不同水压及支护压力条件下的排水能力及抗淤堵能力进行了相关试验,并依托某在建隧道工程对不同土工排水材料在隧道复合式防排水系统中的应用效果进行了现场验证。主要研究成果有:(1)随着支护压力的增加,3种排水材料的排水能力均出现了不同程度的降低,其中,土工布降幅最大,毛细型排水板次之,凸壳型排水板最小;(2)在固定的水压和2层支护间压力条件下,进行20次浑水排水试验后,土工布排水能力发生大幅下降,毛细型排水板和凸壳型排水板排水能力小幅下降,但凸壳型排水板排水夹杂有泥沙,而毛细型排水板排水为清水,表明其抗淤堵能力较好;(3)复合式防排水系统的现场试验数据表明,防水板与二衬间增设排水板,具有良好排水泄压的能力,可有效降低衬砌背后水压。复合式防排水系统的研发可为隧道防排水系统设计和渗漏水病害治理提供借鉴。 | 张素磊 鲍彤 YOO Chungsik 刘昌 李鹏飞 陈立平 | 2021 | 中国公路学报2021，34，4： | 18 |
| 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 | Predictive factors for photic phenomena after refractive,rotationally asymmetric,multifocal intraocular lens implantation显示文摘AIM: To investigate the independent factors associated with photic phenomena in patients implanted with refractive,rotationally asymmetric,multifocal intraocular lenses(MIOLs).METHODS: Thirty-four eyes of 34 patients who underwent unilateral cataract surgery,followed by implantation of rotationally asymmetric MIOLs were included.Distance and near visual acuity outcomes,intraocular aberrations,preferred reading distances,preoperative and postoperative refractive errors,mesopic and photopic pupil diameters,and the mesopic and photopic kappa angles were assessed.Patients were also administered a satisfaction survey.Photic phenomena were graded by questionnaire.Independent-related factors were identified by correlation and bivariate logistic regression analyses.RESULTS: The distance from the photopic to the mesopic pupil center(pupil center shift) was significantly associated with glare/halo symptoms [odds ratio(OR)=2.065,95% confidence interval(CI)=0.916-4.679,P=0.006] and night vision problems(OR=1.832,95% CI=0.721-2.158,P=0.007).The preoperative photopic angle kappa was significantly associated with glare/halo symptoms(OR=2.155,95% CI=1.065-4.362,P=0.041).The photopic angle kappa was also significantly associated with glare/halo symptoms(OR=2.155,95% CI=1.065-4.362,P=0.041) and with night vision problems(OR=1.832,95% CI=0.721-2.158,P=0.007) in patients implanted with rotationally asymmetric MIOLs.CONCLUSION: A large pupil center shift and misalignment between the visual and pupillary axis(angle kappa)may play a role in the occurrence of photic phenomena after implantation of rotationally asymmetric MIOLs. | Hungwon Tchah Kiyeun Nam Aeri Yoo | 2017 | International Journal of Ophthalmology(English edition)2017，10，2： | 15 |
| 19 | Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite. | Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon | 2009 | World Journal of Gastroenterology2009，15，1： | 15 |
| 20 | Transplantation of mesenchymal stem cells from human umbilical cord versus human umbilical cord blood for peripheral nerve regeneration显示文摘BACKGROUND: Mesenchymal stem cells (MSCs) appear to be a good alternative to Schwann cells in the treatment of peripheral nerve injury. Fetal stem cells, like umbilical cord blood (UCB) and umbilical cord (UC) stem cells, have several advantages over adult stem cells. OBJECTIVE: To assess the effects of UC-derived MSCs (UCMSCs) and UCB-derived MSCs (UCBMSCs) in repair of sciatic nerve defects. DESIGN, TIME AND SETTING: A randomized controlled animal experiment was performed at the laboratory of Department of Oral and Maxillofacial Surgery, Seoul National University Dental Hospital, from July to December 2009. MATERIALS: UCMSCs were provided by the Research Institute of Biotechnology, Dongguk University. UCBMSCs were provided by the Laboratory of Stem Cells and Tumor Biology, College of Veterinary Medicine, Seoul National University. Dulbecco's modified Eagle's medium (DMEM) was purchased from Gibco-BRL, USA. METHODS: Seven-week-old Sprague-Dawley rats were randomly and evenly divided into three groups: DMEM, UCBMSCs, and UCMSCs. A 10-mm defect in the left sciatic nerve was constructed in all rats. DMEM (15 μL) containing 1 × 106 UCBMSCs or UCMSCs was injected into the gap between nerve stumps, with the surrounding epineurium as a natural conduit. For the DMEM group, simple DMEM was injected. MAIN OUTCOME MEASURES: At 7 weeks after sciatic nerve dissection, dorsal root ganglia neurons were labeled by fluorogold retrograde labeling. At 8 weeks, electrophysiology and histomorphometry were performed. At 2, 4, 6, and 8 weeks after surgery, sciatic nerve function was evaluated using gait analysis. RESULTS: The UCBMSCs group and the UCMSCs group exhibited similar sciatic nerve function and electrophysiological indices, which were better than the DMEM group, as measured by gait analysis (P < 0.05). Fluorogold retrograde labeling of sciatic nerve revealed that the UCBMSCs group demonstrated a higher number of labeled neurons; however, the differences were not significant. Histomorphometric indices were similar in the UCBMSCs and UCMSCs groups, and total axon counts, particularly axon density (P < 0.05), were significantly greater in the UCBMSCs and UCMSCs groups than in the DMEM group. CONCLUSION: Transplanting either UCBMSCs or UCMSCs into axotomized sciatic nerves could accelerate and promote sciatic nerve regeneration over 8 weeks. Both treatments had similar effects on nerve regeneration. | Kang-Mi Pang Mi-Ae Sung Mohammad S.Alrashdan Sang Bae Yoo Samir Jabaiti Soung-Min Kim Sung-June Kim Myung-Jin Kim Jeong Won Jahng Jong-Ho Lee | 2010 | Neural Regeneration Research2010，5，11： | 15 |
