| 1 | Bedside index for severity in acute pancreatitis:comparison with other scoring systems in predicting severity and organ failure显示文摘BACKGROUND:The early identification of severe acute pancreatitis is important for the management and for improving outcomes.The bedside index for severity in acute pancreatitis(BISAP)has been considered as an accurate method for risk stratification in patients with acute pancreatitis.This study aimed to evaluate the comparative usefulness of the BISAP.METHODS:We retrospectively analyzed 303 patients with acute pancreatitis diagnosed at our hospital from March 2007to December 2010.BISAP,APACHE-II,Ranson criteria,and CT severity index(CTSI)of all patients were calculated.We stratified the number of patiants with severe pancreatitis,pancreatic necrosis,and organ failure as well as the number of deaths by BISAP score.We used the area under the receiveroperating curve(AUC)to compare BISAP with other scoring systems,C-reactive protein(CRP),hematocrit,and body mass index(BMI)with regard to prediction of severe acute pancreatitis,necrosis,organ failure,and death.RESULTS:Of the 303 patiants,31(10.2%)were classified as having severe acute pancreatitis.Organ failure occurred in 23(7.6%)patients,pancreatic necrosis in 40(13.2%),and death in6(2.0%).A BISAP score of 2 was a statistically significant cutoff value for the diagnosis of severe acute pancreatitis,organ failure,and mortality.AUCs for BISAP predicting severe pancreatitis and death were 0.80 and 0.86,respectively,which were similar to those for APACHE-II(0.80,0.87)and Ranson criteria(0.74,0.74)and greater than AUCs for CTSI(0.67,0.42).The AUC for organ failure predicted by BISAP,APACHE-II,Ranson criteria,and CTSI was 0.93,0.95,0.84 and 0.57,respectively.AUCs for BISAP predicting severity,organ failure,and death were greater than those for CRP(0.69,0.80,0.72),hematocrit(0.45,0.35,0.14),and BMI(0.41,0.47,0.17).CONCLUSION:The BISAP predicts severity,death,and especially organ failure in acute pancreatitis as well as APACHE-II does and better than Ranson criteria,CTSI,CRP,hematocrit,and BMI. | Ji Young Park Tae Joo Jeon Tae Hwan Ha Jin Tae Hwang Dong Hyun Sinn Tae-Hoon Oh Won Chang Shin Won-Choong | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，6： | 33 |
| 2 | Small sphincterotomy combined with endoscopic papillary large balloon dilation versus sphincterotomy显示文摘AIM:To compare small sphincterotomy combined with endoscopic papillary large balloon dilation(SES+ ELBD)and endoscopic sphincterotomy(EST)for large bile duct stones. METHODS:We compared prospectively SES+ELBD (group A,n=27)with conventional EST(group B, n=28)for the treatment of large bile duct stones(≥ 15 mm).When the stone could not be removed with a normal basket,mechanical lithotripsy was performed. We compared the rates of complete stone removal with one session and application of mechanical lithotripsy. RESULTS:No significant differences were observed in the mean largest stone size(A:20.8 mm,B:21.3 mm), bile duct diameter(A:21.4 mm,B:20.5 mm),number of stones(A:2.2,B:2.3),or procedure time(A:18 min, B:19 min)between the two groups.The rates of complete stone removal with one session was 85%in group A and 86%in group B(P=0.473).Mechanical lithotripsy was required for stone removal in nine of 27 patients(33%)in group A and nine of 28 patients (32%,P=0.527)in group B.CONCLUSION:SES+ELBD did not show significant benefits compared to conventional EST,especially for the removal of large(≥15 mm)bile duct stones. | Hyun Gun Kim Young Koog Cheon Young Deok Cho Jong Ho Moon Do Hyun Park Tae Hoon Lee Hyun Jong Choi Sang-Heum Park Joon Seong Lee Moon Sung Lee | 2009 | World Journal of Gastroenterology2009，15，34： | 34 |

| 4 | Endoscopic removal of gastric ectopic pancreas:An initial experience with endoscopic submucosal dissection显示文摘AIM:To evaluate the therapeutic usefulness and safety of endoscopic resection in patients with gastric ectopic pancreas.METHODS:A total of eight patients with ectopic pancreas were included.All of them underwent endoscopic ultrasonography before endoscopic resection.Endo-scopic resection was performed by two methods:endo-scopic mucosal resection(EMR)by the injection-and-cut technique or endoscopic mucosal dissection(ESD).RESULTS:We planned to perform EMR in all eight cases but EMR was successful in only four cases.In the other four cases,saline spread into surrounding normal tissues and the lesions becameattened,which made it impossible to remove them by EMR.Inthose four cases,we performed ESD and removed the lesions without any complications.CONCLUSION:If conventional EMR is difficult to remove gastric ectopic pancreas,ESD is a feasible alternative method for successful removal. | Dong Yup Ryu Gwang Ha Kim Do Youn Park Bong Eun Lee Jae Hoon Cheong Dong Uk Kim Hyun Young Woo Jeong Heo Geun Am Song | 2010 | World Journal of Gastroenterology2010，16，36： | 24 |
| 5 | How good is cola for dissolution of gastric phytobezoars?显示文摘AIM:To evaluate the efficacy of cola treatment for gastric phytobezoars,including diospyrobezoars.METHODS:A total of 17 patients(range:48 to 78 years) with symptomatic gastric phytobezoars treated with cola and adjuvant endoscopic therapy were reviewed.Three liters of cola lavage(10 cases) or drink(7 cases) were initially used,and then endoscopic fragmentation was done for the remnant bezoars by using a lithotripsy basket or a polypectomy snare.The overall success of dissolving a gastric phytobezoars with using three liters of cola and the clinical and endoscopic findings were compared retrospectively between four cases of complete dissolution by using only cola and 13 cases of partial dissolution with cola.RESULTS:After 3 L of cola lavage or drinking,a complete dissolution of bezoars was achieved in four patients(23.5%),while 13 cases(76.5%) were only partially dissolved.Phytobezoars(4 of 6 cases) were observed more frequently than diospyrobezoars(0 of 11) in the group that underwent complete dissolution(P = 0.006).Gender,symptom duration,size of bezoar and method of cola administration were not significantly different between the two groups.Twelve of 13 patients with residual bezoars were completely treated with a combination of cola and endoscopic fragmentation.CONCLUSION:The rate of complete dissolution with three liters of cola was 23.5%,but no case of diospyrobezoar was completely dissolved using this method.However,pretreatment with cola may be helpful and facilitate endoscopic fragmentation of gastric phytobezoars. | Beom Jae Lee Jong-Jae Park Hoon Jai Chun Ji Hoon Kim Jong Eun Yeon Yoon Tae Jeen Jae Seon Kim Kwan Soo Byun Sang Woo Lee Jae Hyun Choi Chang Duck Kim Ho Sang Ryu Young-Tae Bak | 2009 | World Journal of Gastroenterology2009，15，18： | 22 |
| 6 | Benefit of neoadjuvant concurrent chemoradiotherapy for locally advanced perihilar cholangiocarcinoma显示文摘AIM To clarify the role of neoadjuvant concurrent chemoradiotherapy(NACCRT) followed by surgical resection for localized or locally advanced perihilar cholangiocarcinoma(CCA).METHODS We retrospectively reviewed 57 patients who underwent surgical resection with or without NACCRT for perihilar CCA; 12 patients received NACCRT and 45 patients did not received NACCRT. Patients with locally advanced perihilar CCA requiring NACCRT were defined as follows:(1) a mass involving unilateral branches of the portal vein or hepatic artery with insufficient volume of the anticipated remnant lobe; or(2) an infiltrating mass in the main portal vein that was too long for reconstruction, identified at preoperative staging. RESULTS The median disease-free survival(DFS) durations of the neoadjuvant and non-neoadjuvant CCRT groups were26.0 and 15.1 mo, respectively(P = 0.91). The median overall survival(OS) durations of the neoadjuvant and non-neoadjuvant CCRT groups were 32.9 and 27.1 mo, respectively(P = 0.26). The NACCRT group showed a downstaging tendency compared to the non-NACCRT group as compared with the tumor stage confirmed by histological examination after surgery and the tumor stage confirmed by imaging test at the time of diagnosis(P = 0.01). CONCLUSION NACCRT does not prolong DFS and OS in localized or locally advanced perihilar CCA. However, NACCRT may allow tumor downstaging and improve tumor resectability. | Jang Han Jung Hyun Jik Lee Hee Seung Lee Jung Hyun Jo In Rae Cho Moon Jae Chung Jeong Youp Park Seung Woo Park Si Young Song Seungmin Bang | 2017 | World Journal of Gastroenterology2017，23，18： | 21 |

| 8 | Clinical and pathological differences between serum immunoglobulin G4-positive and -negative type 1 autoimmune pancreatitis显示文摘AIM: To identify clinical and pathological differences between serum immunoglobulin G4 (IgG4)-positive (SIP) and IgG4-negative (SIN) type 1 autoimmune pancreatitis (AIP) in South Korea. METHODS: AIP was diagnosed by the international consensus diagnostic criteria. The medical records and pathology were retrospectively reviewed and IgG4-positive cells were counted in a high power field (HPF). Type I AIP was defined as a high serum level of IgG4or histological finding. SIN type 1 AIP was defined as a histological evidence of type 1 AIP and a normal serum IgG4 level. The clinical and pathological findings were compared between the two groups. The analysis was performed using Student's t test, Fischer's exact test and Mann-Whitney's U test. A P value of < 0.05 was considered statistically significant. As repeated com- parison was made, P values of less than 5% (P < 0.05) were considered significant. RESULTS: Twenty five patients with definite type 1 AIP (19 histologically and six serologically diagnosed cases) were enrolled. The mean tissue IgG4 concentrations were significantly higher in SIP than SIN group (40 cells per HPF vs 18 cells per HPF, P = 0.02). Among eight SIN patients, the tissue IgG4 concentrations were less than 15 cells per HPF in most of cases, except one. The sensitivity of serum IgG4 was 68% (17 SIP and eight SIN AIP). Other organ involvement was more frequent- ly associated with SIP than SIN AIP (59% vs 26%, P = 0.016). However, the relapse rate and diffuse swelling of the pancreas were not associated with serum IgG4 level. The concentrations of IgG4-positive cells per HPF were higher in SIP than SIN AIP (40 vs 18, P = 0.02). CONCLUSION: The sensitivity of serum IgG4 was 68% in type 1 AIP. High serum IgG4 level was associated with other organ involvement and tissue IgG4 concentration but did not affect the relapse rate in type 1 AIP. | Woo Hyun Paik Ji Kon Ryu Jin Myung Park Byeong Jun Song Joo Kyung Park Yong-Tae Kim Kyoungbun Lee | 2013 | World Journal of Gastroenterology2013，19，25： | 16 |
| 9 | Prognostic significance of the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with stage Ⅲ and Ⅳcolorectal cancer显示文摘AIM To evaluate the prognostic value of the neutrophil-tolymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) in patients with colorectal cancer(CRC).METHODS Between April 1996 and December 2010, medical records from a total of 1868 patients with CRC were retrospectively reviewed. The values of simple inflammatory markers including NLR and PLR in predicting the long-term outcomes of these patients were evaluated using Kaplan-Meier curves and Cox regression models.RESULTS The median follow-up duration was 46 mo(interquartile range, 22-73). The estimation of NLR and PLR was based on the time of diagnosis. In multivariate Cox regression analysis, high NLR (≥ 3.0) and high PLR(≥ 160) were independent risk factors predicting poor long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. However, high NLR and high PLR were not prognostic factors in patients with stage Ⅰ and Ⅱ CRC.CONCLUSION In this study, we identified that high NLR (≥ 3.0) and high PLR (≥ 160) are useful prognostic factors to predict long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. | Jae Hyun Kim Jun Yeop Lee Hae Koo Kim Jin Wook Lee Sung Gyu Jung Kyoungwon Jung Sung Eun Kim Won Moon Moo In Park Seun Ja Park | 2017 | World Journal of Gastroenterology2017，23，3： | 16 |
| 10 | Gender differences in ghrelin, nociception genes, psychological factors and quality of life in functional dyspepsia显示文摘AIM to evaluate gender differences in the aspect of ghrelin,nociception-related genes and psychological aspects and the quality of life(Qo L) in Korean functional dyspepsia(FD) patients.METHODS Total of 191 persons were prospectively enrolled between March 2013 and May 2016 in Seoul National Bundang Hospital,and classified into control and FD group based on ROME Ⅲ criteria. Questionnaire included assessment for dyspepsia symptoms,Qo L and anxiety or depression. Preproghrelin and nociception genes in the gastric mucosa and plasma acyl/des-acyl ghrelin were measured. RESULTS Lower level of plasma acyl ghrelin in FD patients compared to control was significant only in male(15.9 fmol/m L vs 10.4 fmol/m L,P = 0.017). Significantly higher m RNA expressions of nerve growth factor and transient receptor potential vanilloid receptor 1 were observed in male(P = 0.002 and P = 0.014,respectively) than in female. In contrast,female FD patients had a higher anxiety and depression score than male FD(P = 0.029),and anxiety score was correlated with epigastric pain only in female FD patients(female: Spearman rho = 0.420,P = 0.037). The impairment of overall Qo L was more prominent in female FD patients than male patients(5.4 ± 0.3 vs 6.5 ± 0.3,P = 0.020). CONCLUSION Gender differences of ghrelin and nociception-related genes in male and psychological factors in female underlie FD symptoms. More careful assessment of psychological or emotional status is required particularly for the female FD patients. | Yoon Jin Choi Young Soo Park Nayoung Kim Yong Sung Kim Sun Min Lee Dong Ho Lee Hyun Chae Jung | 2017 | World Journal of Gastroenterology2017，23，45： | 16 |
| 11 | 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 |

| 14 | Intraoperative neurophysiological monitoring in spinal surgery显示文摘Recently, many surgeons have been using intraoperative neurophysiological monitoring(IOM) in spinal surgery to reduce the incidence of postoperative neurological complications, including level of the spinal cord, cauda equina and nerve root. Several established technologies are available and combined motor and somatosensory evoked potentials are considered mandatory for practical and successful IOM. Spinal cord evoked potentials are elicited compound potentials recorded over the spinal cord. Electrical stimulation is provoked on the dorsal spinal cord from an epidural electrode. Somatosensory evoked potentials assess the functional integrity of sensory pathways from the peripheral nerve through the dorsal column and to the sensory cortex. For identification of the physiological midline, the dorsal column mapping technique can be used. It is helpful for reducing the postoperative morbidity associated with dorsal column dysfunction when distortion of the normal spinal cord anatomy caused by an intramedullary cord lesion results in confusion in localizing the midline for the myelotomy. Motor evoked potentials(MEPs) consist of spinal, neurogenic and muscle MEPs. MEPs allow selective and specific assessment of the functional integrity of descending motor pathways, from the motor cortex to peripheral muscles. Spinal surgeons should understand the concept of the monitoring techniques and interpret monitoring records adequately to use IOM for the decision making during the surgery for safe surgery and a favorable surgical outcome. | Jong-Hwa Park Seung-Jae Hyun | 2015 | World Journal of Clinical Cases2015，3，9： | 14 |
| 15 | Programmed death ligand-1 expression and its prognostic role in esophageal squamous cell carcinoma显示文摘AIM To investigate the expression and prognostic role of programmed death ligand-1(PD-L1) in locally advanced esophageal squamous cell carcinoma(ESCC).METHODS A total of 200 patients with ESCC who underwent radical esophagectomy with standard lymphadenectomy as the initial definitive treatment in Seoul National University Hospital from December 2000 to April 2013 were eligible for this analysis. Tissue microarrays were constructed by collecting tissue cores from surgical specimens, and immunostained with antibodies directed against PD-L1, p16, and c-Met. Medical records were reviewed retrospectively to assess clinical outcomes. Patients were divided into two groups by PD-L1 status, and significant differences in clinicopathologic characteristics between the two groups were assessed. RESULTS Tumor tissues from 67 ESCC patients(33.5%) were PDL1-positive. Positive p16 expression was observed in 21 specimens(10.5%). The H-score for c-Met expression was ≥ 50 in 42 specimens(21.0%). Although PDL1-positivity was not significantly correlated with any clinical characteristics including age, sex, smoking/alcoholic history, stage, or differentiation, H-scores for c-Met expression were significantly associated with PDL1-positivity(OR = 2.34, 95%CI: 1.16-4.72, P = 0.017). PD-L1 expression was not significantly associated with a change in overall survival(P = 0.656). In contrast, the locoregional relapse rate tended to increase(P = 0.134), and the distant metastasis rate was significantly increased(HR = 1.72, 95%CI: 1.01-2.79, P = 0.028) in patients with PD-L1-positive ESCC compared to those with PD-L1-negative ESCC.CONCLUSION PD-L1 expression is positively correlated with c-Met expression in ESCC. PD-L1 may play a critical role in distant failure and progression of ESCC. | Ryul Kim Bhumsuk Keam Dohee Kwon Chan-Young Ock Miso Kim Tae Min Kim Hak Jae Kim Yoon Kyung Jeon In Kyu Park Chang Hyun Kang Dong-Wan Kim Young Tae Kim Dae Seog Heo | 2016 | World Journal of Gastroenterology2016，22，37： | 14 |
| 16 | Neonatal gastric perforation: A single center experience显示文摘AIM: To determine the etiology and prognostic factors for neonatal gastric perforation(NGP), a rare but life-threatening disease.METHODS: Between 1980 and 2011, nine patients un-derwent surgical intervention for NGP at Seoul National University Children's Hospital. The characteristics and prognosis of the patients were retrospectively analyzed.RESULTS: Among the nine patients, three(33.3%) were preterm babies and five(55.5%) had associated anomalies, which included diaphragmatic eventration(n = 2), congenital diaphragmatic hernia, esophageal atresia with tracheoesophageal fistula, and antral web. Three(33.3%) patients were born before 1990 and three(33.3%) had a birth weight < 2500 g. Pneumo-peritoneum was found on preoperative images in six(66.7%) patients, and incidentally in the other three(33.3%) patients. Surgery was performed within 24 h after the onset of symptoms in seven(77.8%) patients. The overall mortality rate was 22.2%(2/9). The time between symptoms and surgical intervention was the only prognostic factor for survival, whereas premature birth and birth weight were not.CONCLUSION: Early detection and advances in neo-natal intensive care may improve the prognosis of NGP. | Jeik Byun Hyun Young Kim Seung Yeon Noh Soo Hong Kim Sung Eun Jung Seong Cheol Lee Kwi Won Park | 2014 | World Journal of Gastrointestinal Surgery2014，6，8： | 13 |
| 17 | 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 |

| 19 | Electrogastrography associated with symptomatic changes after prokinetic drug treatment for functional dyspepsia显示文摘AIM:To evaluate the effect of prokinetic drugs on electrogastrography(EGG) parameters according to symptomatic changes in patients with functional dyspepsia(FD).METHODS:Seventy-four patients with FD were prospectively enrolled in this study between December 2006 and December 2010.We surveyed the patients using a questionnaire on dyspeptic symptoms before and after an 8-wk course of prokinetic drug treatment.We also measured cutaneous pre-prandial and postprandial EGG recordings including percentage of gastric waves(normogastria,bradygastria,tachygastria),dominant frequency(DF),dominant power(DP),dominant frequency instability coefficient(DFIC),dominant power instability coefficient(DPIC),and the ratio of post-prandial to fasting in DP before and after the 8-wk course of prokinetic drug treatment.RESULTS:Fifty-two patients(70%) achieved symptomatic improvement after prokinetic drug treatment.Patients who had normal gastric slow waves showed symptom improvement group after treatment.Postprandial DF showed a downward trend in the symptom improvement group,especially in the itopride group.Post-prandial DP was increased regardless of symptom improvement,especially in the itopride group and mosapride group.Post-prandial DFIC and DPIC in the symptom improvement group were significantly increased after the treatment.The EGG power ratio was increased after treatment in the symptom improvement group(0.50 ± 0.70 vs 0.93 ± 1.77,P = 0.002),especially in the itopride and levosulpiride groups.CONCLUSION:Prokinetics could improve the symptoms of FD by regulating gastric myoelectrical activity,and EGG could be a useful tool in evaluating the effects of various prokinetics. | Hyun Chul Lim Sang In Lee Jiande DZ Chen Hyojin Park | 2012 | World Journal of Gastroenterology2012，18，41： | 11 |
| 20 | Curcumin attenuates the release of pro-inflammatory cytokines in lipopolysaccharide-stimulated BV2 microglia显示文摘Aim:Pro-inflammatory mediators,such as prostaglandin E_2 (PGE_2) and nitric oxide(NO),and pro-inflammatory cytokines such as interleukin (IL)-1β,IL-6,and TNF-α,play pivotal roles in brain injuries.The anti-inflammatory properties are knownto be associated with significant reductions in pro-inflammatory mediators in braininjuries.In the present study we investigate whether the effects of curcumin onthe production of pro-inflammatory mediators in lipopolysaccharide (LPS)-stimu-lated BV2 microglia.Methods:Curcumin were administered and their effects onLPS-induced pro-inflammatory mediators were monitored by Western blottingand RT-PCR.Result:Curcumin significantly inhibited the release of NO,PGE_2,and pro-inflammatory cytokines in a dose-dependent manner.Curcumin alsoattenuated the expressions of inducible NO synthase and cyclooxygenase-2 mRNAand protein levels.Moreover,curcumin suppressed NF-kB activation via thetranslocation of p65 into the nucleus.Our data also indicate that curcumin exertsanti-inflammatory properties by suppressing the transcription of proinflammatorycytokine genes through the NF-kB signaling pathway.Conclusion:Anti-inflam-matory properties of curcumin may be useful for treating the inflammatory anddeleterious effects of microglial activation in response to LPS stimulation. | Cheng-yun JIN Jae-dong LEE Cheol PARK Yung hyun CHOI Gi-young KIM | 2007 | Acta Pharmacologica Sinica2007，28，10： | 10 |
