| 1 | Eosinophilic gastroenteritis presenting as small bowel obstruction: A case report and review of the literature显示文摘Eosinophilic gastroenteritis is a rare disease of unknown etiology. It is characterized by eosinophilic infiltration of the bowel wall to a variable depth and symptoms associated with gastrointestinal tract. Recently, the authors experienced a case of eosinophilic gastroenteritis presenting as small bowel obstruction. A 51-year old woman was admitted to our hospital complaining of abdominal pain and vomiting. Physical examination revealed a distended abdomen with diffuse tenderness. Complete blood count showed mild leukocytosis without eosinophilia. Computed tomography confirmed a dilatation of the small intestine with ascites. An emergency laparotomy was performed for a diagnosis of peritonitis due to intestinal obstruction. Segmental resection of the ileum and end to end anastomosis were performed. Histologically, there was a dense infiltration of eosinophils throughout the entire thickness of ileal wall and eosinophilic enteritis was diagnosed. The patient recovered well, and was free from gastrointestinal symptoms at the time when we reported her disease. | Min Young Yun Young Up Cho In Suh Park Sun Keun Choi Sei Joong Kim Seok Hwan Shin Kyung Rae Kim | 2007 | World Journal of Gastroenterology2007，13，11： | 19 |
| 2 | Risk prediction platform for pancreatic fistula after pancreatoduodenectomy using artificial intelligence显示文摘BACKGROUND Despite advancements in operative technique and improvements in postoperative managements,postoperative pancreatic fistula(POPF)is a life-threatening complication following pancreatoduodenectomy(PD).There are some reports to predict POPF preoperatively or intraoperatively,but the accuracy of those is questionable.Artificial intelligence(AI)technology is being actively used in the medical field,but few studies have reported applying it to outcomes after PD.AIM To develop a risk prediction platform for POPF using an AI model.METHODS Medical records were reviewed from 1769 patients at Samsung Medical Center who underwent PD from 2007 to 2016.A total of 38 variables were inserted into AI-driven algorithms.The algorithms tested to make the risk prediction platform were random forest(RF)and a neural network(NN)with or without recursive feature elimination(RFE).The median imputation method was used for missing values.The area under the curve(AUC)was calculated to examine the discriminative power of algorithm for POPF prediction.RESULTS The number of POPFs was 221(12.5%)according to the International Study Group of Pancreatic Fistula definition 2016.After median imputation,AUCs using 38 variables were 0.68±0.02 with RF and 0.71±0.02 with NN.The maximal AUC using NN with RFE was 0.74.Sixteen risk factors for POPF were identified by AI algorithm:Pancreatic duct diameter,body mass index,preoperative serum albumin,lipase level,amount of intraoperative fluid infusion,age,platelet count,extrapancreatic location of tumor,combined venous resection,co-existing pancreatitis,neoadjuvant radiotherapy,American Society of Anesthesiologists’score,sex,soft texture of the pancreas,underlying heart disease,and preoperative endoscopic biliary decompression.We developed a web-based POPF prediction platform,and this application is freely available at http://gffzz52cab37b8d4e4d2chcuocok5up6kx6onq.ffgz.tsg.suse.edu.cn This study is the first to predict POPF with multiple risk factors using AI.This platform is reliable(AUC 0.74),so it could be used to select patients who need especially intense therapy and to preoperatively establish an effective treatment strategy. | In Woong Han Kyeongwon Cho Youngju Ryu Sang Hyun Shin Jin Seok Heo Dong Wook Choi Myung Jin Chung Oh Chul Kwon Baek Hwan Cho | 2020 | World Journal of Gastroenterology2020，26，30： | 12 |

| 4 | Alterations of Gefitinib Pharmacokinetics by Co-administration of Herbal Medications in Rats显示文摘Objective: To evaluate the potential pharmacokinetic interactions of the anticancer agent gefitinib(Iressa?) and the oriental medications Guipi Decoction(归脾汤, GPD, Guibi-tang in Korean) and Bawu Decoction(八物汤, BWD, Palmul-tang in Korean). Methods: Methylcellulose(MC, control), GPD(1,200 mg/kg), or BWD(6,000 mg/kg) was orally administered to rats either as a single dose or multiple doses prior to gefitinib administration. To examine the effects of a single dose of the herbal medicines, gefitinib(10 mg/kg) was orally administered after 5 min or 1 h of MC or the herbal medicine pretreatments. To examine the effects of the multiple doses of the herbal medicines, gefitinib(10 mg/kg) was orally administered following 7 consecutive days of the administration of MC or each herbal medicine. The plasma concentrations of gefitinib were determined with liquid chromatography-tandem mass spectrometry assay. The plasma concentration-time profiles of gefitinib were analyzed with a noncompartmental analysis. Results: Gefitinib was rapidly absorbed and showed a monoexponential decline with an elimination half-life of 3.7–4.1 h. The pharmacokinetics of gefitinib was not affected by GPD pretreatment. However, a significantly lower maximum plasma concentration(Cmax, P<0.05) and area under the curve(P<0.05), and a delayed time to reach Cmax(Tmax, P<0.01) were observed in both single-and multipledose BWD-pretreated rats compared with the control rats. Conclusions: BWD and not GPD might delay and interfere with gefitinib absorption. Further evaluations of the clinical significance of these findings are needed. | Kwon-Yeon Weon Min Gi Kim Soyoung Shin Tae Hwan Kim Sang Hoon Joo Eunsook Ma Seok Won Jeong Sun Dong Yoo Yu Seok Youn Beom Soo Shin | 2018 | Chinese Journal of Integrative Medicine2018，24，6： | 2 |
| 5 | Let-7 miRNA and CDK4 siRNA co-encapsulated in Herceptin-conjugated liposome for breast cancer stem cells显示文摘Recently,breast cancer stem cells(BCSCs)have rapidly emerged as a novel target for the therapy of breast cancer as they play critical roles in tumor growth,maintenance,metastasis,and recurrence.Let-7 miRNA is known to be downregulated in a variety of cancers,especially BCSCs,whereas CDK4 being overexpressed in human epidermal growth factor receptor 2(HER-2)overexpressing tumor cells.In this study,let-7 miRNA and CDK4-specific siRNA were chosen as therapeutic agents and co-encapsulated in Herceptinconjugated cationic liposomes for breast cancer therapy.Particle size,zeta potential,and encapsulation efficacy of mi/siRNA-loaded PEGylated liposome conjugated with Herceptin(Her-PEG-Lipo-mi/siRNA)were 176 nm,28.1 mV,and 99.7%±0.1%,respectively.Enhanced cellular uptake(86%)was observed by fluorescence microscopy when SK-BR-3 cells were treated with Her-PEG-Lipo-mi/siRNA.Also,the increased amount of let-7a mRNA and decreased amount of cellular CDK4 mRNA were observed by qRT-PCR when SK-BR-3 cells were treated with Her-PEG-Lipo-mi/siRNA,which was even more so when SK-BR-3 stem cells were used(197 vs 768 times increase for let-7a,62%vs 68%decrease for CDK4).Growth inhibition(65%)andmigration arrest(0.5%)of the cellswere achieved by the treatment of the cells with Her-PEG-Lipo-mi/siRNA,but not withmi/siRNA complex or other formulations.In conclusion,an efficient liposomal delivery system for the combination of miRNA and siRNA to target the BCSCs was developed and could be used as an efficacious therapeuticmodality for breast cancer. | Jeong Hyun Shin Dae Hwan Shin Jin Seok Kim | 2020 | Asian Journal of Pharmaceutical Sciences2020，15，4： | 1 |

| 9 | Periportal thickening on magnetic resonance imaging for hepatic fibrosis in infantile cholestasis显示文摘BACKGROUND Untreated neonatal cholestasis can progress to liver cirrhosis and end stage liver disease in infancy due to prolonged hepatocyte and biliary tree injury and may require liver transplantation.Therefore,non-invasive evaluation of hepatic fibrosis is important in infants with cholestasis.AIM To investigate the usefulness of periportal thickening(PT)measured on liver magnetic resonance imaging(MRI)for the assessment of hepatic fibrosis in infants with cholestasis including biliary atresia(BA).METHODS This retrospective study included infants less than 6 mo who underwent liver MRI and biopsy for the evaluation of infantile cholestasis.PT and spleen size were measured on MRI.Serologic assessment was based on aspartate transaminase to platelet ratio index(APRI).The grade of histopathologic fibrosis was assessed by the METAVIR grading system.Correlation and diagnostic performance of PT,normalized spleen size ratio(SR,using the upper normal size limit),and APRI for diagnosing hepatic fibrosis were obtained by receiveroperating characteristic(ROC)curve analysis.RESULTS A total of 155 patients were included,110 of which were diagnosed with BA.Mean age at the time of MRI was 57.6±34.4 d.There were positive correlations between fibrosis grade and PT and SR,even after adjusting age(all,P<0.001).For the diagnosis of significant fibrosis(METAVIR grade F2-F4),the area under the ROC curve was 0.899(95%CI:0.840–0.941)for PT(cutoff,4.2 mm),which was higher than 0.741(95%CI:0.664–0.808)for SR and 0.712(95%CI:0.634–0.782)for APRI(both,P<0.001).For the diagnosis of cirrhosis(F4),the area under the ROC curve was the highest with SR as 0.790(95%CI:0.718–0.852).CONCLUSION Liver MRI findings of PT and SR are useful to assess clinically significant hepatic fibrosis(F2 and higher)in infants with cholestasis including BA. | Myung Hwan Lee Hyun Joo Shin Haesung Yoon Seok Joo Han Hong Koh Mi-Jung Lee | 2020 | World Journal of Gastroenterology2020，26，21： | 0 |
| 10 | Transanal excision of a malignant fibrous histiocytoma of anal canal:A case report and literature review显示文摘Malignant fibrous histiocytoma, which is composed of spindle-shaped cells arranged in a pleomorphic and storiform pattern, is rarely found in the colorectum. Although complete surgical excision remains the main stem of therapy, an optimal treatment strategy according to the stage has not been elucidated. We report a case of a 63-year-old woman with an ulcerative lesion in the anorectal junction and a final diagnosis of malignant fibrous histiocytoma. We introduced an access for transanal local excision and adjuvant radiotherapy because the patient refused abdominoperineal resection. No local recurrences or distant metastases were observed 15 mo after the operation. To our knowledge, this is the first case reported in the English literature of a malignant fibrous histiocytoma treated with the transana local excision and adjuvant radiotherapy. This report showed that this approach is selectively reserved for early-stage malignant fibrous histiocytoma and for those patients who refuse radical surgery because of the risk in a permanent colostomy. | Beom Gyu Kim In Taik Chang Jun Seok Park Yoo Shin Choi Gi Hyeon Kim Eon Sub Park Chang Hwan Choi | 2008 | World Journal of Gastroenterology2008，14，9： | 0 |
