1Hepatolithiasis and intrahepatic cholangiocarcinoma: A review显示文摘Although the incidence of hepatolithiasis is decreasing as the pattern of gallstone disease changes in Asia, the prevalence of hepatolithiasis is persistently high, especially in Far Eastern countries. Hepatolithiasis is an established risk factor for cholangiocarcinoma(CCA), and chronic proliferative inflammation may be involved in biliary carcinogenesis and in inducing the upregulation of cell-proliferating factors. With the use of advanced imaging modalities, there has been much improvement in the management of hepatolithiasis and the diagnosis of hepatolithiasis-associated CCA(HLCCA). However, there are many problems in managing the strictures in hepatolithiasis and differentiating them from infiltrating types of CCA. Surgical resection is recommended in cases of single lobe hepatolithiasis with atrophy, uncontrolled stricture, symptom duration of more than 10 years, and long history of biliaryenteric anastomosis. Even after resection, patients should be followed with caution for development of HL-CCA, because HL-CCA is an independent prognostic factor for survival. It is not yet clear whether hepatic resection can reduce the occurrence of subsequent HL-CCA. Furthermore, there are no consistent findings regarding prediction of subsequent HL-CCA in patients with hepatolithiasis. In the management of hepatolithiasis, important factors are the reduction of recurrence of cholangitis and suspicion of unrecognized HL-CCA.Hyo Jung Kim Jae Seon Kim Moon Kyung Joo Beom Jae Lee Ji Hoon Kim Jong Eun Yeon Jong-Jae Park Kwan Soo Byun Young-Tae Bak 2015World Journal of Gastroenterology2015,21,48:63
2Small 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 2009World Journal of Gastroenterology2009,15,34:34
3Lower bounds on the periodic Hamming correlations of frequency hopping sequences with low hit zone显示文摘In this paper, several periodic Hamming correlation lower bounds for frequency hopping sequences with low hit zone, with respect to the size p of the frequency slot set, the sequence length L, the family size M, low hit zone LH ( or no hit zone NH ), the maximum periodic Hamming autocorrelation sidelobe Ha and the maximum periodic Hamming crosscorrelation Hc, are established. It is shown that the new bounds include the known Lempel-Greenberger bounds, T.S. Seay bounds and Peng-Fan bounds for the conventional frequency hopping sequences as special cases.PENG Daiyuan FAN Pingzhi LEE Moon Ho 2006Science in China(Series F)2006,49,2:27
4Nutritional risk index as a predictor of postoperative wound complications after gastrectomy显示文摘AIM:To investigate the correlation between the nutritional risk index (NRI) and postoperative wound complications.METHODS:From January 2008 through June 2008,669 patients who underwent curative gastrectomy for gastric cancer were included in a retrospective study.Medical records of consecutive patients were collected and analyzed to determine postoperative wound complication rates.The NRI was assessed on the fifth postoperative day and other possible risk factors for the incidence of wound complications were analyzed to identify the factors affecting postoperative wound complications.Patients with other postoperative complications were excluded from the study.RESULTS:On the 5th postoperative day,the NRI showed a malnutrition rate of 84.6% among postoperative patients.However,postoperative wound complications occurred in only 66/669 (9.86%) patients.Of the patients with wound complications,62/66 (94%) belonged to the malnourished group (NRI < 97.5),and 4/66 (6%) patients to the non-malnourished group (NRI ≥ 97.5).The only factor correlated with wound complications was the NRI on the 5th postoperative day (odds ratio of NRI ≥ 97.5 vs NRI < 97.5:0.653;95% confidence interval:0.326-0.974;P=0.014) according to univariate analysis as well as multivariate analysis.CONCLUSION:This study suggests that malnutrition immediately after surgery may play a significant role in the development of wound complications.Cheong Ah Oh Dae Hoon Kim Seung Jong Oh Min Gew Choi Jae Hyung Noh Tae Sung Sohn Jae Moon Bae Sung Kim 2012World Journal of Gastroenterology2012,18,7:25
5Glycyrrhizin 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 2012World Journal of Gastroenterology2012,18,7:26
6沙尘暴事件中大气颗粒物化学组分的浓度变化和硫酸盐的形成显示文摘应用电感耦合等离子体原子发射光谱、质谱和离子色谱分析了2002年3月28日—4月8日在山东长岛县采集的共11对粗、细大气颗粒物样品的化学组成,探讨4月6—8日沙尘暴事件中大气颗粒物化学组分的变化和硫酸盐的形成。沙尘暴事件应区分前锋和后续部分,前锋与大气中各种污染物相互作用,具有硫富集的特征。后续部分较好地保持了长距离传输风沙尘本身的特征。硫酸盐的形成机理可能是多相氧化而不是简单的酸碱中和。硫酸铵是首先生成的含硫物种,这是细颗粒主导的形成过程。硫酸铵逐渐转化为其他硫酸盐,硫的成分也逐渐向粗颗粒转移。在沙尘暴事件中含硫污染物不但有一个从气相向颗粒物转变的过程,也有一个从细颗粒向粗颗粒转化的过程。刘咸德 董树屏 李冰 高占君 李玉武 MOON Kil-Choo GHIM Young Sung 2005环境科学研究2005,18,6:22
7Benefit 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 2017World Journal of Gastroenterology2017,23,18:21
8Alcoholic liver disease: Treatment显示文摘The excess consumption of alcohol is associated with alcoholic liver diseases(ALD). ALD is a major healthcare problem, personal and social burden, and significant reason for economic loss worldwide. The ALD spectrum includes alcoholic fatty liver, alcoholic hepatitis, cirrhosis, and the development of hepatocellular carcinoma. The diagnosis of ALD is based on a combination of clinical features, including a history of significant alcohol intake, evidence of liver disease, and laboratory findings. Abstinence is the most important treatment for ALD and the treatment plan varies according to the stage of the disease. Various treatments including abstinence, nutritional therapy, pharmacological therapy, psychotherapy, and surgery are currently available. For severe alcoholic hepatitis, corticosteroid or pentoxifylline are recommended based on the guidelines. In addition, new therapeutic targets are being under investigation.Ki Tae Suk Moon Young Kim Soon Koo Baik 2014World Journal of Gastroenterology2014,20,36:20
9Management of the complications of endoscopic submucosal dissection显示文摘Endoscopic submucosal dissection(ESD) is currently widely accepted as a standard treatment option for early gastrointestinal neoplasms in Korea.However,ESD has technical difficulties and a longer procedure time than conventional endoscopic resection.So it may have a higher risk of complications than conventional endoscopic resection techniques.We,the ESD study group of Korean Society of Gastrointestinal Endoscopy,have experienced many complications,mostly treated by endoscopic or conservative management.Here,we introduce and share our experiences for managementof post ESD complications and review published papers on the topic.Seong Hwan Kim Jeong Seop Moon Young Hoon Youn Ki Myung Lee Sung Joon Lee 2011World Journal of Gastroenterology2011,17,31:19
10Favorable surgical treatment outcomes for chronic constipation with features of colonic pseudo-obstruction显示文摘AIM:To determine long-term outcomes of surgical treatments for patients with constipation and features of colonic pseudo-obstruction.METHODS:Consecutive 42 patients who underwent surgery for chronic constipation within the last 13 years were prospectively collected.We identified a subgroup with colonic pseudo-obstruction(CPO) features,with dilatation of the colon proximal to the narrowed transitional zone,in contrast to typical slowtransit constipation(STC),without any dilated colonic segments.The outcomes of surgical treatments for chronic constipation with features of CPO were analyzed and compared with outcomes for STC.RESULTS:Of the 42 patients who underwent surgery for constipation,33 patients had CPO with dilatation of the colon proximal to the narrowed transitional zone.There were 16 males and 17 females with a mean age of 51.2 ± 16.1 years.All had symptoms of chronic intestinal obstruction,including abdominal distension,pain,nausea,or vomiting,and the mean duration of symptoms was 67 mo(range:6-252 mo).Preoperative defecation frequency was 1.5 ± 0.6 times/wk(range:1-2 times/wk).Thirty-two patients underwent total colectomy,and one patient underwent diverting transverse colostomy.There was no surgery-related mortality.Postoperative histologic examination showed hypoganglionosis or agangliosis in 23 patients and hypoganglionosis combined with visceral neuropathy or myopathy in 10 patients.In contrast,histology of STC group revealed intestinal neuronal dysplasia type B(n = 6) and visceral myopathy(n = 3).Early postoperative complications developed in six patients with CPO;wound infection(n = 3),paralytic ileus(n = 2),and intraabdominal abscess(n = 1).Defecation frequencies 3 mo after surgery improved to 4.2 ± 3.2 times/d(range:1-15 times/d).Long-term follow-up(median:39.7 mo) was available in 32 patients;all patients had improvements in constipation symptoms,but two patients needed intermittent medication for management of diarrhea.All 32 patients had distinct improvements in constipation symptoms(with a mean bowel frequency of 3.3 ± 1.3 times/d),social activities,and body mass index(20.5 kg/m 2 to 22.1 kg/m 2) and were satisfied with the results of their surgical treatment.In comparison with nine patients who underwent colectomy for STC without colon dilatation,those in the CPO group had a lower incidence of small bowel obstructions(0% vs 55.6%,P < 0.01) and less difficulty with long-distance travel(6.7% vs 66.7%,P = 0.007) on long-term follow-up.CONCLUSION:Chronic constipation patients with features of CPO caused by narrowed transitional zone in the left colon had favorable outcomes after total colectomy.Eon Chul Han Heung-Kwon Oh Heon-Kyun Ha Eun Kyung Choe Sang Hui Moon Seung-Bum Ryoo Kyu Joo Park 2012World Journal of Gastroenterology2012,18,32:16
11Tenofovir 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 2012World Journal of Gastroenterology2012,18,47:16
12胶质瘤的基因治疗(英文)显示文摘Glioblastoma multiforme(GBM) is a highly invasive brain tumour that is unvaryingly fatal in humans despite even aggressive therapeutic approaches such as surgical resection followed by chemotherapy and radiotherapy.Unconventional treatment options such as gene therapy provide an intriguing option for curbing glioma related deaths.To date,gene therapy has yielded encouraging results in preclinical animal models as well as promising safety profiles in phase I clinical trials,but has failed to demonstrate significant therapeutic efficacy in phase III clinical trials.The most widely studied antiglioma gene therapy strategies are suicide gene therapy,genetic immunotherapy and oncolytic virotherapy,and we have attributed the challenging transition of these modalities into the clinic to four major roadblocks:(1) anatomical features of the central nervous system,(2) the host immune system,(3) heterogeneity and invasiveness of GBM and(4) limitations in current GBM animal models.In this review,we discuss possible ways to jump these hurdles and develop new gene therapies that may be used alone or in synergy with other modalities to provide a powerful treatment option for patients with GBM.Tobias A Ahmed A Moon KS Lesniak MS. 2013中华神经外科疾病研究杂志2013,12,4:16
13Prognostic 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 2017World Journal of Gastroenterology2017,23,3:16
14Prevalence 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 2009World Journal of Gastroenterology2009,15,1:15

16Pre-existing diabetes mellitus increases the risk of gastric cancer:A meta-analysis显示文摘AIM:To systematically assess the association between diabetes and incidence of gastric cancer.METHODS:We searched MedLine (PubMed),EMBASE,and the Cochrane Library without any limitations with respect to publication date or language,we also searched the references of qualifying articles.Casecontrol studies and cohort studies comparing the risk of gastric cancer between diabetic patients and control subjects were included.We excluded studies reporting only standardized incidence ratios without control groups and those that investigated only mortality but not incidence.Seventeen studies met our criteria,and the qualities of these studies were assessed using theNewcastle-Ottawa Quality Assessment Scale.We performed a meta-analysis of pre-existing diabetes and gastric cancer incidence using the DerSimonian-Laird method for random-effects.For subgroup analyses,we separated the studies by study type,region,sex and method to determine confounding factors and reliability.We also conducted subgroup analyses to examine the effects of smoking,Helicobacter pylori (H.pylori) infection,and cancer site.Publication bias was evaluated using Begg's test.RESULTS:A random-effects model meta-analysis showed an increased gastric cancer risk in diabetic patients [relative risk (RR)=1.19;95%CI:1.08-1.31].Subgroup analyses indicated that this result persisted in cohort studies (RR=1.20;95%CI:1.08-1.34),in studies on populations of both Western (RR=1.18;95%CI:1.03-1.36) and Eastern countries (RR=1.19;95%CI:1.02-1.38),in a female subgroup (RR=1.24;95%CI:1.01-1.52),and in highly qualified studies (RR=1.17;95%CI:1.05-1.31).Moreover,these results persisted when the analysis was confined to studies adjusted for well-known gastric cancer risk factors such as smoking (RR=1.17;95%CI:1.01-1.34) and H.pylori infection (RR=2.35;95%CI:1.24-4.46).CONCLUSION:Pre-existing diabetes mellitus may increase the risk of gastric cancer by approximately 19%.This effect seems to be unrelated to geographical region.Jae Moon Yoon Ki Young Son Chun Sick Eom Daniel Durrance Sang Min Park 2013World Journal of Gastroenterology2013,19,6:14
17Colonoscopy evaluation after short-term anti-tuberculosis treatment in nonspecific ulcers on the ileocecal area显示文摘AIM: To evaluate the eff icacy of colonoscopy follow-up after short-term anti-tuberculosis treatment in patients with nonspecific ulcers on ileocecal areas being suspicious of tuberculous colitis. METHODS: We prospectively analyzed the colonoscopic fi ndings before and after short term anti- tuberculosis treatment in 18 patients with nonspecifi c ulcers on the ileocecal area and compared them with 7 patients of confi rmed tuberculous colitis by acid-fast bacilli or caseating granuloma on colonic biopsy. RESULTS: Mean duration for short-term follow- up was 107.3 d with combined chemotherapy containing isoniazid, rifampicin, ethambutol and pyrazinamide. Seven patients with tuberculous colitis showed complete healing of active ulcers after short- term medication. After short-term anti-tuberculosis treatment, follow-up colonoscopy findings devided 18 patients with nonspecific ulcers into two groups by ulcer state. One is the 'suspicious tuberculous colitis group' showing healing of ulcers and erosions and another is the 'suspicious inflammatory bowel disease group' showing active ulcers with or without aggravation of the lesion. Finally, all 9 of the 'suspicious tuberculous colitis group' were diagnosed as tuberculous colitis showing no recurrence of ulcers after termination of 9 mo of anti-tuberculosis medication. Patients of the 'suspicious inflammatorybowel disease group' were f inally diagnosed as Crohn's disease or nonspecifi c colonic ulcers during long-term follow up. CONCLUSION: Follow-up colonoscopy shows a healing stage ulcer or scarring change without an active ulcer with just 2 mo to 3 mo of medication in patients with tuberculous colitis. Colonoscopy follow-up after short term anti-tuberculosis trial in patients with nonspecif ic ulcers on the ileocecal area is valuable in making early differential diagnosis of tuberculous colitis.Young Sook Park Dae Won Jun Seong Hwan Kim Han Hyo Lee Yun Ju Jo Moon Hee Song Nam In Kim Jun Seok Lee 2008World Journal of Gastroenterology2008,14,32:14
18The diluted atropine for inhibition of myopia progression in Korean children显示文摘AIM:To evaluate the efficacy and safety of three different concentrations of diluted atropine for the control of myopia in Korean children,and to assess the risk factors associated with rapid myopia progression.METHODS:A total of 285 children,with refractive errors within the range of-6 diopters(D)between 5 and 14 years of age were included.After using 0.01%,or 0.025%,or 0.05% atropine,for about 1y,changes in refraction,axial lengths and frequency of adverse events were analyzed.Logistic regression analyses were performed to evaluate the risk factors associated with rapid myopia progression.RESULTS:The changes in the mean spherical equivalent values were -0.134 D/mo in the before atropine group,-0.070 D/mo in the 0.01% atropine group,-0.047 D/mo in the 0.025% atropine group,and -0.019 D/mo in the 0.05% atropine group,with significant differences between the groups(P<0.001).The axial elongation was 0.046 mm/mo,0.037 mm/mo,0.025 mm/mo,and 0.019 mm/mo respectively,with significant differences between the groups(P=0.003).The incidence of photophobia and near vision difficulty was not different among the three atropine groups(P=0.425and P=0.356,respectively).Multivariate logistic regression analyses showed that only highly myopic parents were a significant predictive factor of rapid myopia progression in Korean children(odds ratio,8.155;95% confidence interval,3.626-18.342;P<0.001).CONCLUSION:Treatment with 0.01%,0.025% and 0.05% atropine solution inhibits myopia progression in Korean children in a dose-dependent manner.Children with highly myopic parents preferentially shows a rapid myopia progression rate.Ji-Sun Moon Sun Young Shin 2018International Journal of Ophthalmology(English edition)2018,11,10:14
