| 1 | Diagnostic value of PIVKA-Ⅱ and alpha-fetoprotein in hepatitis B virus-associated hepatocellular carcinoma显示文摘AIM: To determine the cutoff values and to compare the diagnostic role of alpha-fetoprotein(AFP) and prothrombin induced by vitamin K absence-Ⅱ(PIVKA-Ⅱ) in chronic hepatitis B(CHB).METHODS: A total of 1255 patients with CHB, including 157 patients with hepatocellular carcinoma(HCC), 879 with non-cirrhotic CHB and 219 with cirrhosis without HCC, were retrospectively enrolled. The areas under the receiver operating characteristic(AUROC) curves of PIVKA-Ⅱ, AFP and their combination were calculated and compared.RESULTS: The optimal cutoff values for PIVKA-Ⅱ and AFP were 40 m AU/m L and 10 ng/m L, respectively, for the differentiation of HCC from nonmalignant CHB. The sensitivity and specificity were 73.9% and 89.7%, respectively, for PIVKA-Ⅱ and 67.5% and 90.3% for AFP, respectively. The AUROC curves of both PIVKA-Ⅱ and AFP were not significantly different(0.854 vs 0.853, P = 0.965) for the differentiation of HCC from nonmalignant CHB, whereas the AUROC of PIVKA-Ⅱ was significantly better than that of AFP in patients with cirrhosis(0.870 vs 0.812, P = 0.042). When PIVKA-Ⅱ and AFP were combined, the diagnostic power improved significantly compared to either AFP or PIVKA-Ⅱ alone for the differentiation of HCC from nonmalignant CHB(P < 0.05), especially when cirrhosis was present(P < 0.05).CONCLUSION: Serum PIVKA-Ⅱ might be a better tumor marker than AFP, and its combination with AFP may enhance the early detection of HCC in patients with CHB. | Seung In Seo Hyoung Su Kim Won Jin Kim Woon Geon Shin Doo Jin Kim Kyung Ho Kim Myoung Kuk Jang Jin Heon Lee Joo Seop Kim Hak Yang Kim Dong Joon Kim Myung Seok Lee Choong Kee Park | 2015 | World Journal of Gastroenterology2015,21,13: | 60 |
| 2 | Comparison of RECIST version 1.0 and 1.1 in assessment of tumor response by computed tomography in advanced gastric cancer显示文摘Objective:Response Evaluation Criteria in Solid Tumors(RECIST)guideline version 1.0(RECIST 1.0)was proposed as a new guideline for evaluating tumor response and has been widely accepted as a standardized measure.With a number of issues being raised on RECIST 1.0,however,a revised RECIST guideline version 1.1(RECIST 1.1)was proposed by the RECIST Working Group in 2009.This study was conducted to compare CT tumor response based on RECIST 1.1 vs.RECIST 1.0 in patients with advanced gastric cancer(AGC).Methods:We reviewed 61 AGC patients with measurable diseases by RECIST 1.0 who were enrolled in other clinical trials between 2008 and 2010.These patients were retrospectively re-analyzed to determine the concordance between the two response criteria using theκstatistic.Results:The number and sum of tumor diameters of the target lesions by RECIST 1.1 were significantly lower than those by RECIST 1.0(P<0.0001).However,there was excellent agreement in tumor response between RECIST 1.1 and RECIST 1.0(κ=0.844).The overall response rates(ORRs)according to RECIST1.0 and RECIST 1.1 were 32.7%(20/61)and 34.5%(20/58),respectively.One patient with partial response(PR)based on RECIST 1.0 was reclassified as stable disease(SD)by RECIST 1.1.Of two patients with SD by RECIST 1.0,one was downgraded to progressive disease and the other was upgraded to PR by RECIST 1.1.Conclusions:RECIST 1.1 provided almost perfect agreement with RECIST 1.0 in the CT assessment of tumor response of AGC. | Gil-Su Jang Min-Jeong Kim Hong-Il Ha Jung Han Kim Hyeong Su Kim Sung Bae Ju Dae Young Zang | 2013 | Chinese Journal of Cancer Research2013,25,6: | 42 |
| 3 | Adverse events related to colonoscopy: Global trends and future challenges显示文摘Colonoscopy is a widely used method for diagnosing and treating colonic disease. The number of colonoscopies is increasing worldwide, and concerns about associated adverse events are growing. Large-scale studies using big data for post-colonoscopy complications have been reported. A colon perforation is a severe complication with a relatively high mortality rate. The perforation rate, as reported in large studies(≥ 50,000 colonoscopies) published since 2000, ranges from 0.005-0.085%. The trend in the overall perforation rate in the past 15 years has not changed significantly. Bleeding is a more common adverse event than perforation. Recent large studies(≥ 50,000 colonoscopies) have reported postcolonoscopy bleeding occurring in 0.001-0.687% of cases. Most studies about adverse events related to colonoscopy were performed in the West, and relatively few studies have been conducted in the East. The incidence of post-colonoscopy complications increases in elderly patients or patients with inflammatory bowel diseases. It is important to use a unified definition and refined data to overcome the limitations of previous studies. In addition, a structured training program for endoscopists and a systematic national management program are needed to reduce post-colonoscopy complications. In this review, we discuss the current trends in colonoscopy related to adverse events, as well as the challenges to be addressed through future research. | Su Young Kim Hyun-Soo Kim Hong Jun Park | 2019 | World Journal of Gastroenterology2019,25,2: | 22 |
| 4 | Hepatitis B viral load affects prognosis of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is a complex disease that is dually challenging to treat due to underlying chronic liver disease in addition to the cancer itself.The prognosis of patients with HCC is determined by intrahepatic tumor status and reserved hepatic function.Hepatitis B virus(HBV)is an established major risk factor of HCC development,and HBV viral load is being increasingly recognized as a prognostic factor in the presence of established HCC.High HBV viral load may affect the prognosis of HBV-related HCC patients in several ways.First,it is associated with more frequent recurrence of HBV-related HCC after treatment.Second,it is associated with more occurrence and severity of potentially life-threatening HBV reactivation.Last,it is associated with more worsened liver function,which limits the therapeutic options for HBV-related HCC.HBV,directly or indirectly,can induce hepatocarcinogenesis.In patients with a high HBV DNA level and subsequent active hepatitis,adhesion molecules expressed on the sinusoidal cells are up-regulated and may increase intrahepatic metastasis.HCC progression after treatment can lead to a poor prognosis by reducing number of normal functioning hepatocytes.Thus,high HBV viral load can affect the prognosis of patientswith HCC by frequent recurrence after treatment for HCC and deterioration of hepatic function associated with HCC progression.Recent meta-analysis showed that antiviral treatment reduces HCC recurrence and liver-related mortality after curative therapy of HCC.Given the strong relationship between high HBV DNA load and poor survival outcome of HCC patients due to cancer progression,it is expected that long-term antiviral therapy results in the sustained HBV suppression,control of inflammation,reduction in HCC progression,and eventually in improved overall survival. | Su Jong Yu Yoon Jun Kim | 2014 | World Journal of Gastroenterology2014,20,34: | 21 |
| 5 | Fruit quality,anthocyanin and total phenolic contents,and antioxidant activities of 45 blueberry cultivars grown in Suwon,Korea显示文摘Blueberry fruits from 45 commercial cultivars (39 northern highbush and 6 half highbush blueberry) grown in Suwon,Korea were analyzed for fruit size,soluble solids content,titratable acidity,total anthocyanin content,total phenolic content,and antioxidant activity.Fruit characteristics varied widely among the 45 blueberry cultivars.Fruit weight ranged from 0.9 to 3.6 g,soluble solids content from 8.3 to 14.3 °Brix,and titratable acidity from 0.8% to 3.6%.Antioxidant activity ranged from 0.7 to 2.1 mg of quercetin equivalents per gram of fresh berries in different blueberry cultivars.Among the 45 blueberry cultivars,high amounts of anthocyanins and polyphenols,and high antioxidant activity were observed in 'Elliott','Rubel','Rancocas',and 'Friendship'. | Jin Gook KIM Hong Lim KIM Su Jin KIM Kyo-Sun PARK | 2013 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013,14,9: | 20 |

| 7 | Recurrence after endoscopic piecemeal mucosal resection for large sessile colorectal polyps显示文摘AIM: To evaluate the safety and outcomes of endoscopic piecemeal mucosal resection (EPMR) for large sessile colorectal polyps. METHODS: The patients enrolled in this study were 47 patients with 50 large sessile polyps (diameter, 2 cm or greater) who underwent EPMR using a submucosal saline injection technique between December 2002 and October 2005. All medical records, including characteristics of the patients and polyps, complications, and recurrences, were retrospectively reviewed. The first follow-up endoscopic examination was performed at 3-6 mo after initial endoscopic resection, and the second at 12 mo postEPMR. Subsequent surveillance colonoscopic examinations were individualized, taking risk factors into account. RESULTS: The patients were 23 men and 24 women,with a mean age of 60 years. Mean polyp size was 30.1 mm. Of 50 polyps identified, 34 (68%) were benign and 16 (32%) were malignant. There were 6 (12%) cases with EPMR-related bleeding: 5 intra-procedural and 1 early post-procedural bleeding. All bleeding episodes were managed by endoscopic clipping or argon beam coagulation. There were no perforations. Recurrence was identified in 5 cases (12.2%): 4 local recurrences detected at 3 mo post-EPMR and 1 local recurrence detected at 14 mo post-EPMR. The recurrence rate after EPMR was 3.1% for benign polyps and 33.3% for malignant polyps (P < 0.05). Median follow-up time was 37 mo. CONCLUSION: EPMR is safe, but should be applied carefully in malignant polyps. Close follow-up endoscopic examinations are necessary for early detection of recurrence. | Guh Jung Seo Dae Kyung Sohn Kyung Su Han Chang Won Hong Byung Chang Kim Ji Won Park Hyo Seong Choi Hee Jin Chang Jae Hwan Oh | 2010 | World Journal of Gastroenterology2010,16,22: | 17 |
| 8 | Somatostatin adjunctive therapy for non-variceal upper gastrointestinal rebleeding after endoscopic therapy显示文摘AIM:To evaluate the effect of pantoprazole with a somatostatin adjunct in patients with acute non-variceal upper gastrointestinal bleeding(NVUGIB).METHODS:We performed a retrospective analysis of a prospective database in a tertiary care university hospital.From October 2006 to October 2008,we enrolled 101 patients with NVUGIB that had a high-risk stigma on endoscopy.Within 24 h of hospital admission,all patients underwent endoscopic therapy.After successful endoscopic hemostasis,all patients received an 80-mg bolus of pantoprazole followed by continuous intravenous infusion(8 mg/h for 72 h).The somatostatin adjunct group(n=49)also received a 250-μg bolus of somatostatin,followed by continuous infusion (250μg/h for 72 h).Early rebleeding rates,disappearance of endoscopic stigma and risk factors associated with early rebleeding were examined.RESULTS:Early rebleeding rates were not significantly different between treatment groups(12.2%vs 14.3%,P=0.766).Disappearance of endoscopic stigma on the second endoscopy was not significantly different between treatment groups(94.2%vs 95.9%,P=0.696).Multivariate analysis showed that the complete Rockall score was a significant risk factor for early rebleeding(P =0.044,OR:9.080,95%CI:1.062-77.595).CONCLUSION:The adjunctive use of somatostatin was not superior to pantoprazole monotherapy after successful endoscopic hemostasis in patients with NVUGIB. | Cheol Woong Choi Dae Hwan Kang Hyung Wook Kim Su Bum Park Kee Tae Park Gwang Ha Kim Geun Am Song Mong Cho | 2011 | World Journal of Gastroenterology2011,17,29: | 15 |

| 10 | Management of entecavir-resistant chronic hepatitis B with adefovir-based combination therapies显示文摘AIM: To evaluate the long-term efficacy adefovir(ADV)-based combination therapies in entecavir(ETV)-resistant chronic hepatitis B(CHB) patients. METHODS: F i fty CHB pat ient s wi t h genotypic resistance to ETV at 13 medical centers in South Korea were included for the analysis. All the patients received rescue therapy with the combination of ADV plus ETV(ADV/ETV,n = 23) or ADV plus lamivudine(LMV)(ADV/LMV,n = 27) for more than 12 mo. Patients were monitored at least every 3-4 mo during ADV-based combination therapy by clinical examination as well as biochemical and virological assessments. Hepatitis B virus(HBV) DNA levels were measured by realtime PCR and logarithmically transformed for analysis. Cumulative rates of virologic response(VR; HBV DNA < 20 IU/m L) were calculated using the Kaplan-Meier method,and the difference was determined by a logrank test. Multivariate logistic regression and Cox proportional hazards models were used to identify independent risk factors significantly associated with short-term and long-term VR,respectively.RESULTS: Baseline median HBV DNA levels were 5.53(2.81-7.63) log10 IU/m L. The most commonly observed ETV genotypic mutation sites were rt184 and rt202. Patients were treated for a median of 27(12-45) mo. Overall,cumulative VR rates at 6,12,24,and 36 mo were 26%,36%,45%,and 68%,respectively. Patients treated with the ADV/ETV combination showed higher cumulative VR rates(35%,43%,65%,and 76%,respectively) than those with the ADV/LAM combination(18%,30%,30%,and 62%,respectively; P = 0.048). In the multivariate analysis,low baseline HBV DNA levels(< 5.2 log10 IU/m L) and initial virologic response at 3 mo(IVR-3; HBV DNA < 3.3 log10 IU/m L after 3 mo) were independent predictive factors for VR. Patients with favorable predictors achieved cumulative VR rates up to 90% at 36 mo. During the same period,the cumulative incidence of virologic breakthrough was as low as 6% in patients with the both favorable predictors.CONCLUSION: If tenofovir is not available,ADV/ETV combination could be considered in ETV-resistant patients with low HBV DNA titers,and may becontinued if IVR-3 is achieved. | Hyoung Su Kim Hyung Joon Yim Myoung Kuk Jang Ji Won Park Sang Jun Suh Yeon Seok Seo Ji Hoon Kim Bo Hyun Kim Sang Jong Park Sae Hwan Lee Sang Gyune Kim Young Seok Kim Jung Il Lee Jin-Woo Lee In Hee Kim Tae Yeob Kim Jin-Wook Kim Sook-Hyang Jeong Young Kul Jung Hana Park Seong Gyu Hwang | 2015 | World Journal of Gastroenterology2015,21,38: | 13 |
| 11 | New magnifying endoscopic classification for superficial esophageal squamous cell carcinoma显示文摘AIM To assess the accuracy of a new magnifying endoscopy(ME)classification for predicting depth of invasion of superficial esophageal squamous cell carcinoma(SESCC).METHODS This study included a total of 70 lesions in 69 patients with SESCC who underwent ME with narrow-band imaging(ME-NBI)before resection from August 2010 to July 2016.Accuracy of ME-NBI for predicting depth of invasion of SESCC was analyzed by using a new ME classification proposed by the Japan Esophageal Society(JES),and interobserver agreement was assessed.RESULTS Overall accuracy of ME-NBI for estimating depth of invasion of SESCC was 78.6%.Sensitivity and specificity of type B1 for tumors limited to the epithelial layer(m1)or invading into the lamina propria(m2)were 71.4%and 100%,respectively.Sensitivity and specificity of type B2 for tumors invading into the muscularis mucosa(m3)or superficial submucosa(≤200μm,sm1)were94.4%and 73.1%,respectively,while those of type B3for tumors invading into the deep submucosa(>200μm,sm2)were 75.0%and 97.8%,respectively.Interobserver agreement was excellent(κ=0.86,95%CI:0.76-0.95).CONCLUSION The recently developed JES ME classification is useful for predicting depth of invasion of SESCC,with reliable interobserver agreement. | Su Jin Kim Gwang Ha Kim Moon Won Lee Hye Kyung Jeon Dong Hoon Baek Bong Eun Lee Geun Am Song | 2017 | World Journal of Gastroenterology2017,23,24: | 13 |
| 12 | Plasma levels of acylated ghrelin in patients with functional dyspepsia显示文摘AIM:To investigate the relationship between plasma acylated ghrelin levels and the pathophysiology of functional dyspepsia.METHODS:Twenty-two female patients with functional dyspepsia and twelve healthy volunteers were recruited for the study.The functional dyspepsia patients were each diagnosed based on the Rome Ⅲ criteria.Eligible patients completed a questionnaire concerning the severity of 10 symptoms.Plasma acylated ghrelin levels before and after a meal were determined in the study participants using a commercial human acylated enzyme immunoassay kit;electrogastrograms were performed for 50 min before and after a standardized 10-min meal containing 265 kcal.RESULTS:There were no significant differences in plasma acylated ghrelin levels between healthy volunteers and patients with functional dyspepsia.However,in patients with functional dyspepsia,there was a negative correlation between fasting plasma acylated ghrelin levels and the sum score of epigastric pain(r =-0.427,P = 0.047) and a positive correlation between the postprandial/fasting plasma acylated ghrelin ratio and the sum score of early satiety(r = 0.428,P =0.047).Additionally,there was a negative correlation between fasting acylated ghrelin plasma levels and fasting normogastria(%)(r =-0.522,P = 0.013).Interestingly,two functional dyspepsia patients showed paradoxically elevated plasma acylated ghrelin levels after the meal.CONCLUSION:Abnormal plasma acylated ghrelin levels before or after a meal may be related to several of the dyspeptic symptoms seen in patients with functional dyspepsia. | Yeon Soo Kim Joon Seong Lee Tae Hee Lee Joo Young Cho Jin Oh Kim Wan Jung Kim Hyun Gun Kim Seong Ran Jeon Hoe Su Jeong | 2012 | World Journal of Gastroenterology2012,18,18: | 12 |
| 13 | Severe acute pancreatitis due to tamoxifen-induced hypertriglyceridemia with diabetes mellitus显示文摘The side effects of tamoxifen are generally mild, including the effect on lipoprotein metabolism. However, there are few cases of severe tamoxifen induced hypertriglyceridemia. Hypertriglyceridemia is a marked risk factor for acute pancreatitis and approximately 2% to 5% of cases of acute pancreatitis are related to drugs. We report on tamoxifen-induced hypertriglyceridemia and acute pancreatitis in a 40 years old woman with type 2 diabetes mellitus occurred by dexamethasone. She was treated with insulin infusion and fenofibrate, and goserelin acetate was started instead of tamoxifen after discharge from the hospital. Also, probable pathogenic hypotheses about the correlation between tamoxifen and dexamethasone induced type 2 diabetes mellitus on severe acute pancreatitis are provided. Clinicians should take care of risks of severe acute pancreatitis on using tamoxifen, especially for patients with dexamethasone induced diabetes mellitus. These individuals should undergo pre-post tamoxifen lipid screening and careful history taking of drugs, including dexamethasone. | Young Ae Kim Sol Lee Ji Woong Jung Yu Jin Kwon Gyeong Bok Lee Dong Gue Shin Sang Su Park Jin Yun Yong-Seog Jang Dong Hui Cho | 2014 | Chinese Journal of Cancer Research2014,26,3: | 12 |
| 14 | Effective treatment strategies other than sorafenib for the patients with advanced hepatocellular carcinoma invading portal vein显示文摘Patients with hepatocellular carcinoma(HCC) accompanying portal vein tumor thrombosis(PVTT) have relatively few therapeutic options and an extremely poor prognosis. These patients are classified into barcelonaclinic liver cancer stage C and sorafenib is suggested as the standard therapy of care. However, overall survival(OS) gain from sorafenib is unsatisfactory and better treatment modalities are urgently required. Therefore, we critically appraised recent data for the various treatment strategies for patients with HCC accompanying PVTT. In suitable patients, even surgical resection can be considered a potentially curative strategy. Transarterial chemoembolization(TACE) can be performed effectively and safely in a carefully chosen population of patients with reserved liver function and sufficient collateral blood flow nearby the blocked portal vein. A recent metaanalysis demonstrated that TACE achieved a substantial improvement of OS in HCC patients accompanying PVTT compared with best supportive care. In addition, transarterial radioembolization(TARE) using yttrium-90 microspheres achieves quality-of-life advantages and is as effective as TACE. A large proportion of HCC patients accompanying PVTT are considered to be proper for TARE. Moreover, TACE or TARE achieved comparable outcomes to sorafenib in recent studies and it was also reported that the combination of radiotherapy with TACE achieved a survival gain compared to sorafenib in HCC patients accompanying PVTT. Surgical resectionbased multimodal treatments, transarterial approaches including TACE and TARE, and TACE-based appropriate combination strategies may improve OS of HCC patients accompanying PVTT. | Su Jong Yu Yoon Jun Kim | 2015 | World Journal of Hepatology2015,7,11: | 12 |
| 15 | Motor function outcomes of pediatric patients with hemiplegic cerebral palsy after rehabilitation treatment:a diffusion tensor imaging study显示文摘Previous diffusion tensor imaging(DTI) studies regarding pediatric patients with motor dysfunction have confirmed the correlation between DTI parameters of the injured corticospinal tract and the severity of motor dysfunction. There is also evidence that DTI parameters can help predict the prognosis of motor function of patients with cerebral palsy. But few studies are reported on the DTI parameters that can reflect the motor function outcomes of pediatric patients with hemiplegic cerebral palsy after rehabilitation treatment. In the present study, 36 pediatric patients with hemiplegic cerebral palsy were included. Before and after rehabilitation treatment, DTI was used to measure the fiber number(FN), fractional anisotropy(FA) and apparent diffusion coefficient(ADC) of bilateral corticospinal tracts. Functional Level of Hemiplegia scale(Fx L) was used to assess the therapeutic effect of rehabilitative therapy on clinical hemiplegia. Correlation analysis was performed to assess the statistical interrelationship between the change amount of DTI parameters and Fx L. DTI findings obtained at the initial and follow-up evaluations demonstrated that more affected corticospinal tract yielded significantly decreased FN and FA values and significantly increased ADC value compared to the less affected corticospinal tract. Correlation analysis results showed that the change amount of Fx L was positively correlated to FN and FA values, and the correlation to FN was stronger than the correlation to FA. The results suggest that FN and FA values can be used to evaluate the motor function outcomes of pediatric patients with hemiplegic cerebral palsy after rehabilitation treatment and FN is of more significance for evaluation. | Jin Hyun Kim Yong Min Kwon Su Min Son | 2015 | Neural Regeneration Research2015,10,4: | 12 |
| 16 | Synthesis and properties of Cr-Al-Si-N films deposited by hybrid coating system with high power impulse magnetron sputtering (HIPIMS) and DC pulse sputtering显示文摘The CrN and Cr-Al-Si-N films were deposited on Si wafer and SUS 304 substrates by a hybrid coating system with high power impulse magnetron sputtering (HIPIMS) and a DC pulse sputtering using Cr and AlSi targets under N2/Ar atmosphere.By varying the sputtering current of the AlSi target in the range of 0-2.5 A,both the Al and Si contents in the films increased gradually from 0 to 19.1% and 11.1% (mole fraction),respectively.The influences of the AlSi cathode DC pulse current on the microstructure,phase constituents,mechanical properties,and oxidation behaviors of the Cr-Al-Si-N films were investigated systematically.The results indicate that the as-deposited Cr-Al-Si-N films possess the typical nanocomposite structure,namely the face centered cubic (Cr,Al)N nano-crystallites are embedded in the amorphous Si3N4 matrix.With increasing the Al and Si contents,the hardness of the film first increases from 20.8 GPa for the CrN film to the peak value of 29.4 GPa for the Cr0.23Al0.14Si0.07 N film,and then decreases gradually.In the meanwhile,the Cr0.23Al0.14Si0.07N film also possesses excellent high-temperature oxidation resistance that is much better than that of the CrN film at 900 or 1000 °C. | Min Su KANG Tie-gang WANG Jung Ho SHIN Roman NOWAK Kwang Ho KIM | 2012 | 中国有色金属学会会刊:英文版2012,22,S3: | 11 |
| 17 | Anti-inflammatory and Antimicrobial Effects of Anthocyanin Extracted from Black Soybean on Chronic Bacterial Prostatitis Rat Model显示文摘Objective: To investigated the anti-inflammatory and antimicrobial effects of anthocyanins extracted from black soybean on the chronic bacterial prostatitis(CBP) rat model.Methods: The SpragueDawley rats were divided into 4 groups,including control,ciprofloxacin,anthocyanins and anthocyanins with ciprofloxacin groups(n=8 in each group).Then,drip infusion of bacterial suspension(Escherichia coli Z17O_2:K_1:H^-) into Sprague-Dawley rats was conducted to induce CBP.In 4 weeks,results of prostate tissue,urine culture,and histological analysis on the prostate were analyzed for each group.Results: The use of ciprofloxacin,anthocyanins,and anthocyanins with ciprofloxacin showed statistically significant decreases in bacterial growth and improvements in the reduction of prostatic inflammation compared with the control group(P<0.05).The anthocyanins with ciprofloxacin group showed a statistically significant decrease in bacterial growth and improvement in prostatic inflammation compared with the ciprofloxacin group(P<0.05).Conclusions: These results suggest that anthocyanins may have anti-inflammatory and antimicrobial effects,as well as a synergistic effect with ciprofloxacin.Therefore,we suggest that the combination of anthocyanins and ciprofloxacin may be effective in treating CBP to obtain a higher rate of treatment success. | Byung Il Yoon Woong Jin Bae Yong Sun Choi Su Jin Kim U Syn Ha Sung-Hoo Hong Dong Wan Sohn Sae Woong Kim | 2018 | Chinese Journal of Integrative Medicine2018,24,8: | 11 |
| 18 | Brain-derived neurotrophic factor mediates macrophage migration inhibitory factor to protect neurons against oxygen-glucose deprivation显示文摘Macrophage migration inhibitory factor(MIF)is a chemokine that plays an essential role in immune system function.Previous studies suggested that MIF protects neurons in ischemic conditions.However,few studies are reported on the role of MIF in neurological recovery after ischemic stroke.The purpose of this study is to identify the molecular mechanism of neuroprotection mediated by MIF.Human neuroblastoma cells were incubated in Dulbecco’s modified Eagle’s medium under oxygen-glucose deprivation(OGD)for 4 hours and then returned to normal aerobic environment for reperfusion(OGD/R).30 ng/mL MIF recombinant(30 ng/mL)or ISO-1(MIF antagonist;50μM)was administered to human neuroblastoma cells.Then cell cultures were assigned to one of four groups:control,OGD/R,OGD/R with MIF,OGD/R with ISO-1.Cell viability was analyzed using WST-1 assay.Expression levels of brain-derived neurotrophic factor(BDNF),microtubule-associated protein 2(MAP2),Caspase-3,Bcl2,and Bax were detected by western blot assay and immunocytochemistry in each group to measure apoptotic activity.WST-1 assay results revealed that compared to the OGD/R group,cell survival rate was significantly higher in the OGD/R with MIF group and lower in the OGD/R with ISO-1 group.Western blot assay and immunocytochemistry results revealed that expression levels of BDNF,Bcl2,and MAP2 were significantly higher,and expression levels of Caspase-3 and Bax were significantly lower in the MIF group than in the OGD/R group.Expression levels of BDNF,Bcl2,and MAP2 were significantly lower,and expression levels of Caspase-3 and Bax were significantly higher in the ISO-1 group than in the OGD/R group.MIF administration promoted neuronal cell survival and induced high expression levels of BDNF,MAP2,and Bcl2(anti-apoptosis)and low expression levels of Caspase-3 and Bax(pro-apoptosis)in an OGD/R model.These results suggest that MIF administration is effective for inducing expression of BDNF and leads to neuroprotection of neuronal cells against hypoxic injury. | Su Hwan Bae Mi Ran Yoo Ye Yeong Kim In Kyung Hong Mi Hee Kim Seung Hak Lee Dae Yul Kim | 2020 | Neural Regeneration Research2020,15,8: | 11 |
| 19 | Preoperative colonoscopy through the colonic stent in patients with colorectal cancer obstruction显示文摘AIM:To evaluate the feasibility of a preoperative colonoscopy through a self-expendable metallic stent(SEMS)and to identify the factors that affect complete colonoscopy.METHODS:A total of 48 patients who had SEMS placement because of acute malignant colonic obstruction underwent preoperative colonoscopy.After effective SEMS placement,patients who showed complete resolution of radiological findings and clinical signs of acute colon obstruction underwent a standard bowel preparation.Preoperative colonoscopy was then performed using a standard colonoscope.If the passage of colonoscope was not feasible gastroscope was used.After colonoscopy,cecal intubation time,grade of bowel preparation,tumor location,stent location,presence of synchronous polyps or cancer,damage to colonoscopy and bleeding,and stent migration after colonoscopy were recorded.RESULTS:Complete evaluation with colonoscope was possible in 30 patients(62.5%).In this group,adenoma was detected in 13 patients(43.3%).The factors that affected complete colonoscopy were also analyzed:Tumor location at an angle;stent placement at an angle;and stent expansion diameter,which affected complete colonoscopy significantly.However in multivariate analysis,stent expansion diameter was the only significant factor that affected complete colonoscopy.Complete evaluation using additional gastroscope was feasible in 42 patients(87.5%).CONCLUSION:Preoperative colonoscopy through the colonic stent using only conventional colonoscope was unfavorable.The narrow expansion diameter of the stent may predict unfavorable outcome.In such a case,using small caliber scope should be considered and may expect successful outcome. | Jin Su Kim Kang Moon Lee Sang Woo Kim Eun Jung Kim Chul Hyun Lim Seong Taek Oh Myung Gyu Choi Kyu Yong Choi | 2014 | World Journal of Gastroenterology2014,20,30: | 11 |
