| 4 | Electro-acupuncture to prevent prolonged postoperative ileus:A randomized clinical trial显示文摘AIM:To examine whether acupuncture can prevent prolonged postoperative ileus(PPOI)after intraperitoneal surgery for colon cancer. METHODS:Ninety patients were recruited from the Fudan University Cancer Hospital,Shanghai,China. After surgery,patients were randomized to receive acupuncture(once daily,starting on postoperative day 1, for up to six consecutive days)or usual care.PPOI was defined as an inability to pass flatus or have a bowel movement by 96 h after surgery.The main outcomes were time to first flatus,time to first bowel movement, and electrogastroenterography.Secondary outcomes were quality of life(QOL)measures,including pain, nausea,insomnia,abdominal distension/fullness,and sense of well-being. RESULTS:No significant differences in PPOI on day 4 (P=0.71)or QOL measures were found between the groups.There were also no group differences when the data were analyzed by examining those whose PPOI had resolved by day 5(P=0.69)or day 6(P= 0.88).No adverse events related to acupuncture were reported. CONCLUSION:Acupuncture did not prevent PPOI andwas not useful for treating PPOI once it had developed in this population. | M Kay Garcia Joseph S Chiang Bob Thornton J Lynn Palmer Jennifer McQuade Lorenzo Cohen | 2010 | World Journal of Gastroenterology2010,16,1: | 27 |

| 8 | Usefulness of serum des-γ-carboxy prothrombin in detection of hepatocellular carcinoma显示文摘AIM: To evaluate whether DCP is better than AFP for differentiating HCC from nonmalignant liver disease and further evaluate the usefulness of DCP in early diagnosis of small HCC.METHODS: Serum DCP and AFP levels were determined in 127 patients. Among these patients, 32 were with noncirrhotic chronic hepatitis, 34 were with compensated cirrhosis, and 61 were with HCC. The cut-off value for the DCP and AFP were set as 40 mAU/mL and 20 ng/mL,respectively. To compare the diagnostic value of DCP and AFP in distinguishing HCC from nonmalignant chronic liver disease, receiver operating characteristic (ROC) curves were constructed for each assay.RESULTS: The accuracy, sensitivity, and specificity of DCP were higher than AFP in detecting HCC (81.9%, 77%,and 86.4% vs 68.5%, 59%, and 77.3%, respectively).The area under the ROC (AUROC) curves revealed that DCP had a better accuracy than AFP in diagnosis of HCC (0.85 [95%CT, 0.78-0.91] vs 0.73 [95%CI, 0.65-0.81],P = 0.013). In 39 patients with solitary HCC, the positive rates of DCP were 100% in patients with tumor size larger than 3 cm, 66.7% in patients with tumor size 2-3 cm and50% in patients with tumor size less than 2 cm. The positive rates of AFP in patients with tumor size larger than 3 cm, 2-3 cm and less than 2 cm were 55.6%, 50%,and 33.3%, respectively. The median level of DCP in HCC patients with tumor size larger than 3 cm was significantly higher than those with tumor size 2-3 cm and those with the size of less than 2 cm.CONCLUSION: Our study indicates that DCP has a better diagnostic value than AFP in differentiating HCC from nonmalignant chronic liver disease. DCP has not only a stronger correlation with HCC than AFP in tumor size but also more effectiveness than AFP in detecting small size of HCC. | Chaur-Shine Wang Chin-Lin Lin Hsi-Chang Lee Kuan-Yang Chen Ming-Feng Chiang Hung-Sheng Chen Tsung-Jung Lin | 2005 | World Journal of Gastroenterology2005,11,39: | 18 |
| 9 | Osthole treatment ameliorates Th2-mediated allergic asthma and exerts immunomodulatory effects on dendritic cell maturation and function显示文摘Osthole,an active component of Chinese herbal medicines,reportedly possesses various pharmacological properties and has potential therapeutic applications.This study explored the anti-allergic effects of osthole in asthmatic mice and investigated the immunomodulatory actions of osthole on dendritic cells(DCs)and T cells.Herein,we show that oral administration of osthole to BALB/c mice after ovalbumin(OVA)sensitization ameliorated all of the cardinal features of T helper 2(Th2)-mediated allergic asthma;namely,the production of OVA-specific immunoglobulin E,airway hyperresponsiveness,airway inflammation and the production of Th2-type cytokines including interleukin(IL)-4,IL-5 and IL-13.Surprisingly,IL-10 production was not inhibited and was even enhanced by osthole treatment.We observed a significant increase in the percentages of IL-10-producing DCs and forkhead box P3-positive regulatory T(Treg)cells in osthole-treated asthmatic mice.Additionally,in vitro analyses revealed that osthole-treated bone-marrow-derived DCs had a partial maturation phenotype,secreting large amounts of IL-10 and low levels of proinflammatory cytokines,such as IL-12,IL-6 and tumor necrosis factor-α,and displaying reduced levels of MHC class II surface molecules.These DCs displayed immunosuppressive capacity by directly inhibiting effector T-cell responses or inducing Treg cells.In addition,osthole directly inhibited the activated CD4+T-cell proliferation and Th1/Th2-type cytokine production in this system.Collectively,these results suggest that DCs and T cells are potential target cells responsible for the action of osthole against allergic asthma. | Chen-Yuan Chiang Chen-Chen Lee Chia-Kwung Fan Huei-Mei Huang Bor-Luen Chiang Yueh-Lun Lee | 2017 | Cellular & Molecular Immunology2017,14,11: | 15 |

| 11 | Conservation and Diversity of MicroRNA-associated Copper-regulatory Networks in Populus trichocarpa显示文摘Plants develop important regulatory networks to adapt to the frequently-changing availability of copper (Cu). However, little is known about miRNA-associated Cu-regulatory networks in plant species other than Arabidopsis. Here, we report that Cu-responsive miRNAs in Populus trichocarpa (Torr. & Gray) include not only conserved miR397, miR398 and miR408, but also Populus-specific miR1444, suggesting the conservation and diversity of Cu-responsive miRNAs in plants. Copper-associated suppression of mature miRNAs is in company with the up-regulation of their target genes encoding Cu-containing proteins in Populus. The targets include miR397-targeted PtLAC5, PtLAC6 and PtLAC110a, miR398- targeted PtCSD1, PtCSD2a and PtCSD2b, miR408-targeted PtPCL1, PtPCL2, PtPCL3 and PtLAC4, and miR1444-targeted PtPPO3 and PtPPO6. Consistently, P. trichocarpa miR408 promoter-directed GUS gene expression is down-regulated by Cu in transgenic tobacco plants. Cu-response elements (CuREs) are found in the promoters of Cu-responsive miRNA genes. We identified 34 SQUAMOSA-promoter binding protein-like (SPL) genes, of which 17 are full-length PtSPL proteins or partial sequences with at least 300 amino acids. Phylogenetic analysis indicates that PtSPL3 and PtSPL4 are CuRE-binding proteins controlling Cu-responsive gene expression. Cu appears to be not involved in the regulation of these transcription factors because neither PtSPL3 nor PtSPL4 is Cu-regulated and no CuRE exists in their promoters. | Shanfa Lu Chenmin Yang Vincent L.

| 12 | Computed tomography-guided percutaneous core needle biopsy in pancreatic tumor diagnosis显示文摘AIM: To evaluate the techniques, results, and complications related to computed tomography(CT)-guided percutaneous core needle biopsies of solid pancreatic lesions.METHODS: CT-guided percutaneous biopsies of solid pancreatic lesions performed at a cancer reference center between January 2012 and September 2013 were retrospectively analyzed. Biopsy material was collected with a 16-20 G Tru-Core needle(10-15 cm; Angiotech, Vancouver, CA) using a coaxial system and automatic biopsy gun. When direct access to the lesion was not possible, indirect(transgastric or transhepatic) access or hydrodissection and/or pneumodissection maneuvers were used. Characteristics of the patients, lesions, procedures, and histologic results were recorded using a standardized form. RESULTS: A total of 103 procedures included in the study were performed on patients with a mean age of 64.8 year(range: 39-94 year). The mean size of the pancreatic lesions was 45.5 mm(range: 15-195 mm). Most(75/103, 72.8%) procedures were performed via direct access, though hydrodissection and/or pneumodissection were used in 22.2%(23/103) of cases and indirect transhepatic or transgastric access was used in 4.8%(5/103) of cases. Histologic analysis was performed on all biopsies, and diagnoses were conclusive in 98.1%(101/103) of cases, confirming3.9%(4/103) of tumors were benign and 94.2%(97/103) were malignant; results were atypical in 1.9%(2/103) of cases, requiring a repeat biopsy to diagnose a neuroendocrine tumor, and surgical resection to confirm a primary adenocarcinoma. Only mild/moderate complications were observed in 9/103 patients(8.7%),and they were more commonly associated with biopsies of lesions located in the head/uncinate process(n =8), than of those located in the body/tail(n = 1) of the pancreas, but this difference was not significant.CONCLUSION: CT-guided biopsy of a pancreatic lesion is a safe procedure with a high success rate, and is an excellent option for minimally invasive diagnosis. | Chiang J Tyng Maria Fernanda A Almeida Paula NV Barbosa Almir GV Bitencourt José Augusto AG Berg Macello S Maciel Felipe JF Coimbra Luiz Henrique O Schiavon Maria Dirlei Begnami Marcos D Guimares Charles E Zurstrassen Rubens Chojniak | 2015 | World Journal of Gastroenterology2015,21,12: | 14 |
| 13 | Helicobacter pylori infection concomitant with metabolic syndrome further increase risk of colorectal adenomas显示文摘AIM: To investigate the association of colorectal adenomas with both Helicobacter pylori (H. pylori) infection and metabolic syndrome. METHODS: Using a cross-sectional hospital-based study, we analyzed physical examination data from 9311 healthy subjects with overnight physical examinations performed between January 2004 and December 2006. Examined data included gender, age, life style, anthropometric measurements, blood pressure, biochemical and hematological studies, H. pylori infection detected by esophagogastroduodenoscopy and biopsy urease tests, and colorectal adenomas detected with a complete total colonoscopy. RESULTS: The prevalence values for H. pylori infection, metabolic syndrome, and colorectal adenoma were39.2%, 18.7%, and 20.7%, respectively. Colorectal adenoma risk factors included male gender [odd ratio (OR): 2.005, 95% conf idence interval (CI): 1.740-2.310, P < 0.001], advanced age (OR: 1.046, 95% CI: 1.040-1.052, P < 0.001), smoking (OR: 1.377, 95% CI: 1.146-1.654, P = 0.001), increased body fat (OR: 1.016, 95% CI: 1.007-1.026, P = 0.001), higher white blood cell count (OR: 1.038, 95% CI: 1.005-1.073, P = 0.025), H. pylori infection (OR: 1.366, 95% CI: 1.230-1.517, P < 0.001), and metabolic syndrome (OR: 1.408, 95% CI: 1.231-1.610, P < 0.001). In addition, concomitant H. pylori infection with metabolic syndrome further increased the probability of colorectal adenomas. CONCLUSION: Our study revealed H. pylori infection with concomitant metabolic syndrome might further increase the risk of colorectal adenomas. | Ying-Lung Lin Jui-Kun Chiang Shih-Min Lin Chih-En Tseng | 2010 | World Journal of Gastroenterology2010,16,30: | 13 |

| 15 | Synergistic effect of fatty liver and smoking on metabolic syndrome显示文摘AIM:To investigate the association of fatty liver and smoking on metabolic syndrome and its components.METHODS:This cross-sectional study enrolled participants who attended annual health screening at Shin Kong Wu Ho-Su Memorial Hospital from January to December 2005.A total of 3455(1981 men and 1474 women) subjects were included in final analyses.Fatty liver was diagnosed using abdominal ultrasonography by trained gastroenterologists.The modified National Cholesterol Education Program Adult Treatment Panel Ⅲ was used to define metabolic syndrome.The associations between smoking,fatty liver and metabolic syndrome were analyzed using multiple logistic regression.RESULTS:Subjects with fatty liver,and who smoked tobacco,had the highest odds ratios(ORs) for high waist circumference [OR,4.5(95% CI:3.3-6.1) ,P < 0.05],hypertriglyceridemia [OR,8.1(95% CI:6.0-10.9) ,P < 0.05],low serum high-density lipoprotein cholesterol(HDL-C) [OR,8.3(95% CI:6.1-11.3) ,P < 0.05],and metabolic syndrome [OR,9.5(95% CI:6.7-13.4) ,P < 0.05] compared to subjects without fatty liver who did not smoke tobacco.We also found that the ORs for hypertriglyceridemia,low serum HDL-C,and metabolic syndrome for subjects with fatty liver who smoked tobacco had greater than the sum of the ORs for subjects with fatty liver who did not smokeplus those who did not have fatty liver and who did smoke.CONCLUSION:Fatty liver and smoking had a synergistic effect on metabolic syndrome and its components,especially for hypertriglyceridemia and low serum HDL-C. | Po-Hsin Chiang Tsui-Yen Chang Jong-Dar Chen | 2009 | World Journal of Gastroenterology2009,15,42: | 12 |
| 16 | Peliosis hepatis complicated by portal hypertension following renal transplantation显示文摘Peliosis hepatis(PH)is a vascular lesion of the liver that mimics a hepatic tumor.PH is often associated with underlying conditions,such as chronic infection and tumor malignancies,or with the use of anabolic steroids,immunosuppressive drugs,and oral contraceptives.Most patients with PH are asymptomatic,but some present with abdominal distension and pain.In some cases,PH may induce intraperitoneal hemorrhage and portal hypertension.This study analyzed a 46-year-old male who received a transplanted kidney nine years prior and had undergone long-term immunosuppressive therapy following the renal transplantation.The patient experienced progressive abdominal distention and pain in the six months prior to this study.Initially,imaging studies revealed multiple liver tumor-like abnormalities,which were determined to be PH by pathological analysis.Because the hepatic lesions were progressively enlarged,the patient suffered from complications related to portal hypertension,such as intense ascites and esophageal varices bleeding.Although the patient was scheduled to undergo liver transplantation,he suffered hepatic failure and died prior to availability of a donor organ. | Chia-Ying Yu Liang-Che Chang Li-Wei Chen Tsung-Shih Lee Rong-Nan Chien Ming-Fang Hsieh Kun-Chun Chiang | 2014 | World Journal of Gastroenterology2014,20,9: | 11 |
| 17 | Percutaneous transgastric computed tomography-guided biopsy of the pancreas using large needles显示文摘AIM:To assess the safety,yield and clinical utility of percutaneous transgastric computed tomography(CT)-guided biopsy of pancreatic tumor using large needles, in selected patients. METHODS:We reviewed 34 CT-guided biopsies in patients with pancreas mass,of whom 24(71%)had a direct path to the mass without passing through a major organ.The needle passed through the liver in one case(3%).Nine passes(26%)were made through the stomach.These nine transgastric biopsies which used a coaxial technique(i.e.a 17-gauge coaxial introducer needle and an 18-gauge biopsy needle)were the basis of this study.Immediate and late follow-up CT images to detect complications were obtained. RESULTS:Tumor tissues were obtained in nine pancreatic biopsies,and histologic specimens for diagnosis were obtained in all cases.One patient,who had a rare sarco-matoid carcinoma,received a second biopsy.One patient had a complication of transient pneumoperitoneum but no subjective complaints.An immediate imaging study and clinical follow-up detected neither hemorrhage nor peritonitis.No delayed procedure-related complication was seen during the survival period of our patients.CONCLUSION:Pancreatic biopsy can be obtained by a transgastric route using a large needle as an alternative method,without complications of peritonitis or bleeding. | Hsiuo-Shan Tseng Chia-Yuen Chen Wing P Chan Jen-Huey Chiang | 2009 | World Journal of Gastroenterology2009,15,47: | 11 |
| 18 | 不平衡负载工况下三相变流器有源功率解耦控制显示文摘三相电压源型变流器(VSC)对于微电网的稳定运行有着重要的作用。然而,孤岛工况下带三相不平衡负载运行时,交流侧产生的二次脉动功率耦合至直流侧,导致系统的工作性能降低并影响系统的寿命。针对该问题,在二次功率脉动分析的基础上,提出了一种基于虚拟三相瞬时功率的解耦控制策略,通过控制虚拟三相瞬时功率脉动分量为0,在不增加开关器件的情况下,利用LCL滤波器中电容提供负载所需二次脉动功率,实现交直流侧二次脉动功率解耦。在此基础上进一步分析了该拓扑结构直流侧所需的最低电压以及电流应力影响因素。最后仿真和实验结果均表明所提控制策略可以较好地实现功率解耦控制,直流侧源电流二次脉动分量大大减小,有利于提高系统控制性能和实现直流侧电容轻量化。 | 许泽富 唐芬 周家宇 辛振 Poh Chiang Loh | 2019 | 电网技术2019,43,3: | 11 |
| 19 | Ursolic acid: An overview on its cytotoxic activities against breast and colorectal cancer cells显示文摘Ursolic acid(UA) is a pentacyclic triterpene of the ursane type. As a common chemical constituent among species of the family Lamiaceae, UA possesses a broad spectrum of pharmacological properties. This overview focuses on the anticancer properties of UA against breast cancer(BC) and colorectal cancer(CRC)that are most common among women and men, respectively. In vitro studies have shown that UA inhibited the growth of BC and CRC cell lines through various molecular targets and signaling pathways.There are several in vivo studies on the cytotoxic activity of UA against BC and CRC. UA also inhibits the growth of other types of cancer. Studies on structural modifications of UA have shown that the –OH groups at C3 and at C28 are critical factors influencing the cytotoxic activity of UA and its derivatives.Some needs for future research are suggested.

| 20 | Structure and Potential Application of Konjac Glucomannan Nano Microfibril Aerogel显示文摘An ultra-light and high porosity nano microfibril aerogel was prepared from konjac glucomannan(KGM) by the electrospinning and freeze-drying. The structure of aerogel was analyzed by scanning electron microscopy(SEM) and X-ray diffraction(XRD) while the density and compressive strength of the samples were studied separately. Results reveal that porous network structure of the KGM nano microfibril aerogel is constructed by intermolecular hydrogen bonds in random and interpenetrate way. The nano microfibril structure presents in the KGM aerogel,which is an important reason of its high density and compressive strength. There is a potential application for this unique nano microfibril aerogel in the absorption of biodegradation bacteria to solve problems in marine oil spill pollution. | 陈涵 穆若郡 庞杰 谭小丹 王敏 Chiang Wei-Yin | 2016 | Chinese Journal of Structural Chemistry2016,35,1: | 10 |
