| 1 | Comparative study of chitosan/fibroin–hydroxyapatite and collagen membranes for guided bone regeneration in rat calvarial defects: micro-computed tomography analysis显示文摘This study aimed to utilize micro-computed tomography(micro-CT)analysis to compare new bone formation in rat calvarial defects using chitosan/fibroin–hydroxyapatite(CFB–HAP)or collagen(Bio-Gide)membranes.Fifty-four(54)rats were studied.A circular bony defect(8 mm diameter)was formed in the centre of the calvaria using a trephine bur.The CFB–HAP membrane was prepared by thermally induced phase separation.In the experimental group(n518),the CFB–HAP membrane was used to cover the bony defect,and in the control group(n518),a resorbable collagen membrane(Bio-Gide)was used.In the negative control group(n518),no membrane was used.In each group,six animals were euthanized at 2,4 and 8 weeks after surgery.The specimens were then analysed using micro-CT.There were significant differences in bone volume(BV)and bone mineral density(BMD)(P,0.05)between the negative control group and the membrane groups.However,there were no significant differences between the CFB–HAP group and the collagen group.We concluded that the CFB–HAP membrane has significant potential as a guided bone regeneration(GBR)membrane. | Jae Min Song Sang Hun Shin Yong Deok Kim Jae Yeol Lee Young Jae Baek Sang Yong Yoon Hong Sung Kim | 2014 | International Journal of Oral Science2014，6，2： | 15 |
| 2 | Endoscopic papillary large balloon dilation for the removal of bile duct stones显示文摘Endoscopic papillary large balloon dilation(EPLBD)with endoscopic sphincterotomy(EST)has been widely used as the alternative to EST along with endoscopic mechanical lithotripsy(EML)for the removal of large or difficult bile duct stones.Furthermore,EPLBD without EST was recently introduced as its simplified alternative technique.Thus,we systematically searched PubMed,Medline,the Cochrane Library and EMBASE,and analyzed all gathered data of EPLBD with and without EST,respectively,by using a single standardized definition,reviewing relevant literatures,published between 2003and June 2013,where it was performed with largediameter balloons(12-20 mm).The outcomes,including the initial success rate,the rate of needs for EML,and the overall success rate,and adverse events were assessed in each and compared between both of two procedures:'EPLBD with EST'and'EPLBD without EST'.A total of 2511 procedures from 30 published articles were included in EPLBD with EST,while a total of413 procedures from 3 published articles were included in EPLBD without EST.In the results of outcomes,the overall success rate was 96.5%in EPLBD with EST and97.2%in EPLBD without EST,showing no significant difference between both of them.The initial success rate(84.0%vs 76.2%,P<0.001)and the success rate of EPLBD without EML(83.2%vs 76.7%,P=0.001)was significantly higher,while the rate of use of EML was significantly lower(14.1%vs 21.6%,P<0.001),in EPLBD with EST.The rate of overall adverse events,pancreatitis,bleeding,perforation,other adverse events,surgery for adverse events,and fatal adverse events were 8.3%,2.4%,3.6%,0.6%,1.7%,0.2%and 0.2%in EPLBD with EST and 7.0%,3.9%,1.9%,0.5%,0.7%,0%and 0%in EPLBD without EST,respectively,showing no significant difference between both of them.In conclusion,recent accumulated results of EPLBD with or even without EST suggest that it is a safe and effective procedure for the removal of large or difficult bile duct stones without any additional risk of severe adverse events,when performed under appropriate guidelines. | Jin Hong Kim Min Jae Yang Jae Chul Hwang Byung Moo Yoo | 2013 | World Journal of Gastroenterology2013，19，46： | 12 |
| 3 | Prognostic value of inflammation-based markers in patients with pancreatic cancer administered gemcitabine and erlotinib显示文摘AIM: To evaluate the value of systemic inflammationbased markers as prognostic factors for advanced pancreatic cancer(PC). METHODS: Data from 82 patients who underwent combination chemotherapy with gemcitabine and erlotinib for PC from 2011 to 2014 were collected retrospectively. Data that included the neutrophil-to-lymphocyte ratio(NLR), the platelet-to-lymphocyte ratio, and the C-reactive protein(CRP)-to-albumin(CRP/Alb) ratio were analyzed. Kaplan-Meier curves, and univariate and multivariate Cox proportional hazards regression analyses were used to identify the prognostic factors associated with progression-free survival(PFS) and overall survival(OS). RESULTS: The univariate analysis demonstrated the prognostic value of the NLR(P = 0.049) and the CRP/Alb ratio(P = 0.047) in relation to PFS, and a positiverelationship between an increase in inflammation-based markers and a poor prognosis in relation to OS. The multivariate analysis determined that an increased NLR(hazard ratio = 2.76, 95%CI: 1.33-5.75, P = 0.007) is an independent prognostic factor for poor OS. There was no association between the PLR and the patients' prognoses in those who had received chemotherapy that comprised gemcitabine and erlotinib in combination. The Kaplan-Meier method and the log-rank test determined significantly worse outcomes in relation to PFS and OS in patients with an NLR > 5 or a CRP/Alb ratio > 5.CONCLUSION: Systemic inflammation-based markers, including increases in the NLR and the CRP/Alb ratio, may be useful for predicting PC prognoses. | Jae Min Lee Hong Sik Lee Jong Jin Hyun Hyuk Soon Choi Eun Sun Kim Bora Keum Yeon Seok Seo Yoon Tae Jeen Hoon Jai Chun Soon Ho Um Chang Duck Kim | 2016 | World Journal of Gastrointestinal Oncology2016，8，7： | 12 |
| 4 | Biopathologic features and clinical significance of micrometatasis in the lymph node of early gastric cancer显示文摘AIM: To evaluate the biopathologic features and clinical significance of nodal micrometastasis(MI) in early gastric cancer(EGC).METHODS: Among 1022 EGC patients who underwent gastrectomy with lymphadenectomy of D1 + β or more from March 2001 to December 2005 at the Korean National Cancer Center, available nodal metastasis was found in 90 p T1N1 patients. Nodal metastasis was confirmed by immunohistochemistry(IHC) with cytokeratin and patients were classified into MI and macrometastasis(MA) groups based on the main tumor burden according to the 6th International Union Against Cancer/American Joint Committee on Cancer staging system; the main tumor burden with a diameter of greater than 0.2 mm but no greater than 2 mm as MI, and greater than 2 mm as MA of the representative metastatic node. Proliferative and apoptotic activities of the primary tumor and the nodal metastasis were measured by IHC with Ki-67 and terminal deoxynucleotidyl transferase d UTP nick end labeling, respectively. Biopathologic and clinical features of the patients were analyzed and compared between MI and MA groups. Patients with recurrence were compared with those without recurrence to identify risk factors for recurrence.RESULTS: Thirty-seven patients showed MI and the other 53 patients revealed MA in the lymph node; the incidence of patients with MI and MA was 41.1% and 58.9%. The main tumor burden was 0.9 and 4.6 mm in the representative metastatic node, respectively. Japanese N2 stations were more frequently involved in MA group(20.9%) than in MI group(10.3%) butthe difference was not statistically different(P = 0.338). Proliferative and apoptotic activities of MI were decreased than those of MA(26.7% vs 40.5%, P = 0.004 and 1.0% vs 3.0%, P < 0.001, respectively). However, nodal MI in the current study showed a relatively high proliferative activity and an equivalent apoptotic activity compared to other cancers in the previously published studies. Recurrence was observed in 6 patients during the mean follow up period of 87.6 ± 26.2 mo. The recurrence was significantly associated with the presence of MA(P = 0.041) and lymphovascular invasion of the primary tumor(P = 0.032).CONCLUSION: Lymphadenectomy of D1 + β or more might be necessary in patients with MI in sentinel node to prevent recurrence by clearing MI involving Japanese N2 station. | Min Jung Jo Ji Yeon Park Joon Seon Song Myeong-Cherl Kook Keun Won Ryu Soo-Jeong Cho Jun Ho Lee Byung-Ho Nam Eun Kyung Hong Il Ju Choi Young-Woo Kim | 2015 | World Journal of Gastroenterology2015，21，2： | 9 |
| 5 | Endoscopic submucosal tunnel dissection salvage technique for ulcerative early gastric cancer显示文摘Endoscopic submucosal dissection is an effective treatment modality for early gastric cancer(EGC), though the submucosal fibrosis found in ulcerative EGC is an obstacle for successful treatment. This report presents two cases of ulcerative EGC in two males, 73- and 80-year-old, with severe fibrosis. As endoscopic ultrasonography suggested that the EGCs had invaded the submucosal layer, the endoscopic submucosal tunnel dissection salvage technique was utilized for complete resection of the lesions. Although surgical gastrectomy was originally scheduled, the two patients had severe coronary heart disease, and surgeries were refused because of the risks associated with their heart conditions. The endoscopic submucosal tunnel dissection salvage technique procedures described in these cases were performed under conscious sedation, and were completed within 30 min. The complete en bloc resection of EGC using endoscopic submucosal tunnel dissection salvage technique was possible with a free resection margin, and no other complications were noted during the procedure. This is the first known report concerning the use of the endoscopic submucosal tunnel dissection salvage technique salvage technique for treatment of ulcerative EGC. We demonstrate that endoscopic submucosal tunnel dissection salvage technique it is a feasible method showing several advantages over endoscopic submucosal dissection for cases of EGC with fibrosis. | Hyuk Soon Choi Hoon Jai Chun Min Ho Seo Eun Sun Kim Bora Keum Yeon Seok Seo Yoon Tae Jeen Hong Sik Lee Soon Ho Um Chang Duck Kim Ho Sang Ryu | 2014 | World Journal of Gastroenterology2014，20，27： | 8 |
| 6 | Risk factors for hepatocellular carcinoma in patients with drug-resistant chronic hepatitis B显示文摘AIM:To investigate the risk factors and characteristics of hepatocellular carcinoma(HCC) in the patients with drug-resistant chronic hepatitis B(CHB).METHODS:A total of 432 patients with drug-resistant CHB were analyzed retrospectively from January 2004to December 2012. The patients were divided into two groups:the HCC group(n = 57) and the non-HCC group(n = 375). Two groups compared using logistic regression for various patients and viral characteristics in order to identify associated risk factors for HCC.Secondarily,patient and tumor characteristics of HCC patients with na ve CHB(N group,n = 117) were compared to the HCC group(R group,n = 57) to identify any difference in HCC characteristics between them.RESULTS:A significant difference was found for age,platelet count,alpha-fetoprotein(AFP),positivity of HBeAg,seroconversion rate of HBeAg,virologic response,the Child-Pugh score,presence of rtM204I,and the duration of antiviral treatment in non-HCC and HCC group. Cirrhosis,age(> 50 years),HBeAg(+),virologic non-responder status,and rtM204I mutants were independent risk factors for the development of HCC. The R group had lower serum C-reactive protein(CRP) and AFP levels,earlier stage tumors,and a shorter mean tumor surveillance period than the N group. However,the total follow-up duration was not significantly different between the two groups.CONCLUSION:13.2% of patients with drug-resistant CHB developed HCC. Age,cirrhosis,YIDD status,HBeAg status,and virologic response are associated with risk of HCC. Patients with drug-resistant CHB and these clinical factors may benefit from closer HCC surveillance. | Chung Hwan Jun Hyoung Ju Hong Min Woo Chung Seon Young Park Sung Bum Cho Chang Hwan Park Young Eun Joo Hyun Soo Kim Sung Kyu Choi Jong Sun Rew | 2013 | World Journal of Gastroenterology2013，19，40： | 7 |
| 7 | Gastric metastasis from primary lung adenocarcinoma mimicking primary gastric cancer显示文摘Gastric metastases from lung adenocarcinoma are rare. Because gastric metastasis grossly resembles advanced gastric cancer, it is difficult to diagnose gastric metastasis especially when the histology of the primary lung cancer is adenocarcinoma. We describe a case of gastric metastasis from primary lung adenocarcinoma mimicking Borrmann type Ⅳ primary gastric cancer. A 68-year-old man with known lung adenocarcinoma with multiple bone metastases had been experiencing progressive epigastric pain and dyspepsia over one year. Esophagogastroduodenoscopy revealed linitis plasticalike lesions in the fundus of the stomach. Pathologic examination revealed a moderately differentiated adenocarcinoma with submucosal infiltration. Positive immunohistochemical staining for thyroid transcription factor-1(TTF-1) and napsin A(Nap-A) confirmed that the metastasis was pulmonary in origin. The patient had been treated with palliative chemotherapy for the lung cancer and had lived for over fifteen months after the diagnosis of gastric metastasis. Clinicians should be aware of the possibility of gastric metastasis in patients with primary lung adenocarcinoma, and additional immunohistochemical staining for Nap-A as well as TTF-1 may help in differentiating its origin. | Min Ji Kim Ji Hyung Hong Eun Su Park Jae Ho Byun | 2015 | World Journal of Gastrointestinal Oncology2015，7，3： | 6 |
| 8 | How to improve patient satisfaction during midazolam sedation for gastrointestinal endoscopy?显示文摘AIM To determine the procedure-related factors that affect sedation satisfaction and to make a suggestion to improve it.METHODS We prospectively enrolled a total of 456 patients who underwent outpatient endoscopy procedures with midazolam sedation between March 2014 and August 2014. All patients completed both pre- and postendoscopy questionnaires about sedation expectations and satisfaction. RESULTS The study cohort included 167 (36.6%) patients whounderwent esophagogastroduodenoscopy (EGD), 167 (36.6%) who underwent colonoscopy, and 122(26.8%) who underwent a combined procedure (EGD and colonoscopy). Over 80% of all patients were satisfied with sedation using midazolam. In univariate and multivariate analyses, total procedure time in the EGD group, younger age (≤ 50 years), and longer colonoscopy withdrawal time in the colonoscopy group were related to decreased satisfaction with sedation. However, in active monitoring and intervention group, there was no decrease in grade of satisfaction despite longer procedure time due to more procedures during colonoscopy. Younger age (≤ 50 years), longer interprocedure time gap, and colonoscopy withdrawal time were related to decreased satisfaction in the combined EGD and colonoscopy group. CONCLUSION Midazolam is still a safe and effective sedative for gastrointestinal endoscopy. Satisfaction with sedation depends on several factors including age(≤ 50 years) and procedure time duration. To improve patient satisfaction with sedation, active monitoring of sedation status by the endoscopist should be considered for patients who require long procedure time. | Eun Hyo Jin Kyoung Sup Hong Young Lee Ji Yeon Seo Ji Min Choi Jaeyoung Chun Sang Gyun Kim Joo Sung Kim Hyun Chae Jung | 2017 | World Journal of Gastroenterology2017，23，6： | 6 |
| 9 | Primary malignant melanoma of uterine cervix: a suggestion of new scheme of treatment combination显示文摘Historically, the lack of melanocytes in the vaginal and cervical mucus membranes has deterred the findings of primary melanomas. Mainly due to its rarity, difficulty to diagnose, and poor prognosis, there has been no absolute agreement on comprehensive treatment so far. In this case report, we present a case of a 46-year-old woman with primary malignant melanoma of uterine cervix. She underwent neo-adjuvant chemotherapy initially followed by a radical hysterectomy. After adjuvant concurrent chemo-radiation, the patient has been followed up for 24 months. So far, she has not shown any symptoms or signs of recurrence. Further studies with more cases based on variable combinations of treatment regimen have been on the way. | Kyung-Jin Min Yeun-Sun Kim Jin-Hwa Hong Jae-Kwan Lee Dae-Sik Yang | 2014 | Chinese Journal of Cancer Research2014，26，3： | 5 |

| 12 | Treatment for gastric ‘indefinite for neoplasm/dysplasia' lesions based on predictive factors显示文摘BACKGROUND Gastric ‘indefinite for neoplasm/dysplasia'(IFND) is a borderline lesion that is difficult to diagnose as either regenerative or neoplastic. There is a need for guidance in the identification of a subset of patients, who have an IFND lesion with a higher risk of malignant potential, to enable risk stratification and optimal management.AIM To determine the clinical and pathologic factors for the accurate diagnosis of gastric IFND lesions.METHODS In total, 461 gastric lesions diagnosed via biopsy as IFND lesions were retrospectively evaluated. Endoscopic resection(n = 134), surgery(n = 22), and follow-up endoscopic biopsy(n = 305) were performed to confirm the diagnosis.The time interval from initial biopsy to cancer diagnosis was measured, and diagnostic delays were categorized as > 2 wk, > 2 mo, > 6 mo, and > 1 year. The IFND lesions presenting as regenerating atypia(60%) or atypical epithelia(40%)at initial biopsy were adenocarcinomas in 22.6%, adenomas in 8.9%, and gastritis in 68.5% of the cases.RESULTS Four clinical factors [age ≥ 60 years(2.445, 95%CI: 1.305-4.580, P = 0.005),endoscopic size ≥ 10 mm(3.519, 95%CI: 1.891-6.548, P < 0.001), single lesion(5.702, 95%CI: 2.212-14.696, P < 0.001), and spontaneous bleeding(4.056, 95%CI:1.792-9.180, P = 0.001)], and two pathologic factors [atypical epithelium(25.575,95%CI: 11.537-56.695, P < 0.001], and repeated IFND diagnosis [6.022, 95%CI:1.822-19.909, P = 0.003)] were independent risk factors for gastric cancer. With two or more clinical factors, the sensitivity and specificity for carcinoma were91.3% and 54.9%, respectively. Ten undifferentiated carcinomas were initially diagnosed as IFND. In the subgroup analysis, fold change(5.594, 95%CI: 1.458-21.462, P = 0.012) predicted undifferentiated or invasive carcinoma in the submucosal layers or deeper. Diagnostic delays shorter than 1 year were not associated with worse prognoses. Extremely well-differentiated adenocarcinomas accounted for half of the repeated IFND cases and resulted in low diagnostic accuracy even on retrospective blinded review.CONCLUSION More than two clinical and pathologic factors each had significant cut-off values for gastric carcinoma diagnosis; in such cases, endoscopic resection should be considered. | Mi Jung Kwon Ho Suk Kang Hyeon Tae Kim Jin Woo Choo Bo Hyun Lee Sung Eun Hong Kun Ha Park Dong Min Jung Hyun Lim Jae Seung Soh Sung Hoon Moon Jong Hyeok Kim Hye-Rim Park Soo Kee Min Jin won Seo Ji-Young Choe | 2019 | World Journal of Gastroenterology2019，25，4： | 4 |
| 13 | Computed tomography findings for predicting severe acute hepatitis with prolonged cholestasis显示文摘AIM: To evaluate the significance of computed tomography (CT) findings in relation to liver chemistry and the clinical course of acute hepatitis. METHODS: Four hundred and twelve patients with acute hepatitis who underwent enhanced CT scanning were enrolled retrospectively. Imaging findings were analyzed for the following variables: gallbladder wall thickness (GWT), arterial heterogeneity, periportal tracking, number and maximum size of lymph nodes, presence of ascites, and size of spleen. The serum levels of alanine aminotransferase, alkaline phosphatase, bilirubin, albumin, and prothrombin time were measured on the day of admission and CT scan, and laboratory data were evaluated every 2-4 d for all subjects during hospitalization. RESULTS: The mean age of patients was 34.4 years, and the most common cause of hepatitis was hepatitis A virus (77.4%). The mean GWT was 5.2 mm. The number of patients who had findings of arterial heterogeneity, periportal tracking, lymph node enlargement > 7 mm, and ascites was 294 (80.1%), 348 (84.7%), 346 (84.5%), and 56 (13.6%), respectively. On multivariate logistic regression, male gender [odds ratio (OR) = 2.569, 95%CI: 1.477-4.469, P = 0.001], toxic hepatitis (OR = 3.531, 95%CI: 1.444-8.635, P = 0.006), level of albumin (OR = 2.154, 95%CI: 1.279-3.629, P = 0.004), and GWT (OR = 1.061, 95%CI: 1.015-1.110, P = 0.009) were independent predictive factors for severe hepatitis. The level of bilirubin (OR = 1.628, 95%CI: 1.331-1.991, P < 0.001) and GWT (OR = 1.172, 95%CI: 1.024-1.342,P = 0.021) were independent factors for prolonged cholestasis in multivariate analysis. CONCLUSION: In patients with acute hepatitis, GWT on CT scan was an independent predictor of severe hepatitis and prolonged cholestasis. | Sang Jung Park Jin Dong Kim Yeon Seok Seo Beom Jin Park Min Ju Kim Soon Ho Um Chang Ha Kim Hyung Joon Yim Soon Koo Baik Jin Yong Jung Bora Keum Yoon Tae Jeen Hong Sik Lee Hoon Jai Chun Chang Duck Kim Ho Sang Ryu | 2013 | World Journal of Gastroenterology2013，19，16： | 4 |
| 14 | Efficacy and safety of controlled-release oxycodone/naloxone versus controlled-release oxycodone in Korean patients with cancer-related pain: a randomized controlled trial显示文摘Background: Controlled-release oxycodone/naloxone(OXN-CR) maintains the effect of opioid-induced analgesia through oxycodone while reducing the occurrence rate of opioid-induced constipation through naloxone. The present study was designed to assess the non-inferiority of OXN-CR to controlled-release oxycodone(OX-CR) for the control of cancer-related pain in Korean patients.Methods: In this randomized, open-labeled, parallel-group, phase IV study, we enrolled patients aged 20 years or older with moderate to severe cancer-related pain [numeric rating scale(NRS) pain score ≥4] from seven Korean oncology/hematology centers. Patients in the intention-to-treat(ITT) population were randomized(1:1) to OXNCR or OX-CR groups. OXN-CR was administered starting at 20 mg/10 mg per day and up-titrated to a maximum of80 mg/40 mg per day for 4 weeks, and OX-CR was administered starting at 20 mg/day and up-titrated to a maximum of 80 mg/day for 4 weeks.The primary efficacy endpoint was the change in NRS pain score from baseline to week4, with non-inferiority margin of-1.5. Secondary endpoints included analgesic rescue medication intake, patientreported change in bowel habits, laxative intake, quality of life(QoL), and safety assessments.Results: Of the ITT population comprising 128 patients, 7 with missing primary efficacy data and 4 who violated the eligibility criteria were excluded from the efficacy analysis. At week 4, the mean change in NRS pain scores was not significantly different between the OXN-CR group(n = 58) and the OX-CR group(n = 59)(-1.586 vs.-1.559,P = 0.948). The lower limit of the one-sided 95% confidence interval(-0.776 to 0.830) for the difference exceeded the non-inferiority margin(P < 0.001). The OXN-CR and OX-CR groups did not differ significantly in terms of analgesic rescue medication intake, change in bowel habits, laxative intake, QoL, and safety assessments.Conclusions: OXN-CR was non-inferior to OX-CR in terms of pain reduction after 4 weeks of treatment and had a similar safety profile. Studies in larger populations of Korean patients with cancer-related pain are needed to further investigate the effectiveness of OXN-CR for long-term pain control and constipation alleviation.Trial registration ClinicalTrials.gov NCT01313780, registered March 8。 | Kyung-Hee Lee Tae Won Kim Jung-Hun Kang Jin-Soo Kim Jin-Seok Ahn Sun-Young Kim Hwan-Jung Yun Young-Jun Eum Sung Ae Koh Min Kyoung Kim Yong Sang Hong Jeong Eun Kim Gyeong-Won Lee | 2017 | Chinese Journal of Cancer2017，36，11： | 4 |

| 16 | Effects of Salvia miltiorrhiza Bunge extract and its single components on monosodium urate-induced pain in vivo and lipopolysaccharide-induced inflammation in vitro显示文摘OBJECTIVE:To investigate the possible antinociceptive effects of Salvia(S.)miltiorrhiza Bunge and its single components in monosodium urate(MSU)-induced pain model in mice and lipopolysaccharide(LPS)-induced inflammation model in RAW264.7 cells.METHODS:Pretreatment of S.miltiorrhiza Bunge extract(from 1 to 50μg/mL)concentration-dependently attenuated LPS-induced nitric oxide(NO)release.The extract of S.miltiorrhiza Bunge(50 or 100 mg/kg)also caused reversals of decreased threshold for pain in the MSU-treated group as measured by Von-Frey test.Furthermore,we assessed the antinociceptive and anti-inflammatory properties of the active single components from S.miltiorrhiza Bunge such as 15,16-dihydrotanshinoneⅠ,tanshinoneⅠ,cryptotanshinone,miltirone,tanshinoneⅡA,and salvianolic acid B.Some of them showed an anti-inflammatory effect in LPS-induced NO release model and an antinociceptive effect in MSU-treated pain model.RESULTS:Our results suggest that S.miltiorrhiza Bunge extract may exert anti-inflammatory effect by reducing LPS-induced NO release and an antinociceptive property in MSU-treated pain model.Especially,tanshinoneⅡA,miltirone,cryptotanshinone,and 15,16-dihydrotanshinoneⅠ,not only appear to be responsible for LPS-induced NO release induced by S.miltiorrhiza Bunge,but also in the production of S.miltiorrhiza Bunge extract-induced antinociception in MSU-treated pain model.CONCLUSION:Therefore,the analgesic and anti-inflammatory property of S.miltiorrhiza Bunge indicate it as a therapeutic potential candidate for the treatment of pain and inflammation. | FENG Jinghui Set Byeol Kim Hee Jung Lee Su Min Sim Soon Sung Lim Hong Won Suh | 2021 | Journal of Traditional Chinese Medicine2021，41，2： | 4 |
| 17 | MRI of magnetically labeled mesenchymal stem cells in hepatic failure model显示文摘AIM:To track intravascularly transplanted mesenchymal stem cells (MSCs) labeled with superparamagnetic iron oxide (SPIO) by using magnetic resonance imaging (MRI) in an experimental rabbit model of hepatic failure.METHODS:Human MSCs labeled with FDA-approved SPIO particles (Feridex) were transplanted via the mes-enteric vein into rabbits (n=16) with carbon tetrachloride-induced hepatic failure.Magnetic resonance (MR) examinations were performed with a 3.0 T clinical scanner immediately before and 2 h and 1,3,and 7 d after transplantation.Signal intensity (SI) changes on T2weighted MRI were measured,and correlation between MR findings and histomorphologic findings was also investigated.RESULTS:SI on T2-weighted MRI decreased significantly in the liver 2 h after injection of human MSCs and returned gradually to the levels found before injection in 7 d.Changes in SI in the liver at 2 h,1,3,and 7 d were 41.87% ± 9.63%,10.42% ± 4.3%,5.12% ± 1.9%,3.75% ± 1.2%,respectively (P < 0.001).Histologic analyses confirmed the presence of MSCs in the liver,localized mainly in the sinusoids in early period (2 h and 1 d) and concentrated to the border zone in late period (3 and 7 d).The number of iron-positive cells in the liver at 2 h and on 1,3 and 7 d after transplantation was 29.2 ± 4.8,10.1 ± 3.7,6.7 ± 2.2,and 5.8 ± 2.1,respectively (P=0.013).CONCLUSION:Intravascularly injected SPIO-labeled MSCs in an experimental rabbit model of hepatic failure can be detected and followed with MRI. | Kyu Ri Son Se Young Chung Hyo-Cheol Kim Hoe Suk Kim Seung Hong Choi Jeong Min Lee Woo Kyung Moon | 2010 | World Journal of Gastroenterology2010，16，44： | 4 |
| 18 | Periodontitis combined with smoking increases risk of the ulcerative colitis: A national cohort study显示文摘BACKGROUND Periodontitis is a chronic inflammation of periodontal tissues.The effect of periodontitis on the development of inflammatory bowel disease(IBD)remains unclear.AIM To assessed the risk of IBD among patients with periodontitis,and the risk factors for IBD related to periodontitis.METHODS A nationwide population-based cohort study was performed using claims data from the Korean National Healthcare Insurance Service.In total,9950548 individuals aged≥20 years who underwent national health screening in 2009 were included.Newly diagnosed IBD[Crohn’s disease(CD),ulcerative colitis(UC)]using the International Classification of Disease 10th revision and rare intractable disease codes,was compared between the periodontitis and nonperiodontitis groups until 2017.RESULTS A total of 1092825 individuals(11.0%)had periodontitis.Periodontitis was significantly associated with older age,male gender,higher body mass index,quitting smoking,not drinking alcohol,and regular exercise.The mean age was 51.4±12.9 years in the periodontitis group and 46.6±14.2 years in the nonperiodontitis group(P<0.01),respectively.The mean body mass index was 23.9±3.1 and 23.7±3.2 in the periodontitis and non-periodontitis groups,respectively(P<0.01).Men were 604307(55.3%)and 4844383(54.7%)in the periodontitis and non-periodontitis groups,respectively.The mean follow-up duration was 7.26 years.Individuals with periodontitis had a significantly higher risk of UC than those without periodontitis[adjusted hazard ratio:1.091;95%confidence interval(CI):1.008-1.182],but not CD(adjusted hazard ratio:0.879;95%confidence interval:0.731-1.057).The risks for UC were significant in the subgroups of age≥65 years,male gender,alcohol drinker,current smoker,and reduced physical activity.Current smokers aged≥65 years with periodontitis were at a 1.9-fold increased risk of UC than non-smokers aged≥65 years without periodontitis.CONCLUSION Periodontitis was significantly associated with the risk of developing UC,but not CD,particularly in current smokers aged≥65 years. | Eun Ae Kang Jaeyoung Chun Jee Hyun Kim Kyungdo Han Hosim Soh Seona Park Seung Wook Hong Jung Min Moon Jooyoung Lee Hyun Jung Lee Jun-Beom Park Jong Pil Im Joo Sung Kim | 2020 | World Journal of Gastroenterology2020，26，37： | 3 |
| 19 | Understanding microstructure and mechanical properties of(AlTa(0.76))xCoCrFeNi(2.1) eutectic high entropy alloys via thermo-physical parameters显示文摘(AlTa(0.76))xCoCrFeNi(2.1)(x values in molar ratio,x=0.1,0.3,0.5,0.7,1.0,and 1.5) alloys were designed to investigate the microstructure and mechanical properties of the eutectic high entropy alloys(EHEAs)consisting of FCC,B2,and Laves phases.Depending on the compositional variatio,clear microstructural variation was observed,as follows:(1) Group 1:FCC dendrite+Laves interdendrite(x=0.1),(2) Group 2:FCC dendrite+fine-eutectic structure consisting of FCC and Laves phases(x=0.3,0.5 and 0.7),(3) Group 3:B2 dendrite+bimodal eutectic structure [FCC/B2+Laves](x=1.0),(4) Group 4:Laves dendrite+eutectic structure consisting of B2 and Laves phases(x=1.5).As the fraction of Laves or B2 phases increases,yield stress increases from 293 to 2336 MPa,while the plastic strain decreases from 50 % to 2%.Thermo-physical parameters,such as mixing entropy(△S(mix)),mixing enthalpy(△H(mix)),valence electron concentration(VEC),and atomic size difference(δr),were calculated to understand the microstructural variation.Two criteria(δr-VEC and δr-△H(mix)) were utilized to elucidate the formation of the eutectic structures in the present EHEAs,revealing the usefulness of the thermo-physical parameters in the development of EHEAs. | Min Jung Kim Gyeol Chan Kang Sung Hwan Hong Hae Jin Park Sang Chul Muna Gian Song Ki Buem Kim | 2020 | Journal of Materials Science & Technology2020，54，22： | 3 |
| 20 | Effects of traditional Chinese herbal medicine San-HuangXie-Xin-Tang on gastrointestinal motility in mice显示文摘AIM: To investigate the effects of San-Huang-Xie-XinTang(SHXXT), a herbal product used in traditional Chinese medicine, on gastrointestinal(GI) motility in mice.METHODS: The in vivo effects of SHXXT on GI motility were investigated by measuring the intestinal transit rates(ITRs) using Evans blue in normal mice and in mice with experimentally induced GI motility dysfunction(GMD).RESULTS: In normal ICR mice, ITRs were significantly and dose-dependently increased by SHXXT(0.1-1 g/kg). GMD was induced by injecting acetic acid or streptozotocin intraperitoneally. The ITRs of GMD mice were significantly reduced compared to normal mice, and these reductions were significantly and dose-dependently inhibited by SHXXT(0.1-1 g/kg).CONCLUSION: These results suggest that SHXXT is a novel candidate for the development of a prokinetic agent that may prevent or alleviate GMD. | Min Woo Hwang Tae Seok Ahn Noo Ri Hong Han-Sol Jeong Myeong Ho Jung Ki-Tae Ha Byung Joo Kim | 2015 | World Journal of Gastroenterology2015，21，4： | 3 |
