1Differing coping mechanisms, stress level and anorectal physiology in patients with functional constipation显示文摘AIM: To investigate coping mechanisms, constipation symptoms and anorectal physiology in 80 constipated subjects and 18 controls.METHODS: Constipation was diagnosed by Rome Ⅱ criteria.Coping ability and anxiety/depression were assessed by validated questionnaires. Transit time and balloon distension test were performed.RESULTS: 34.5% patients were classified as slow transit type of constipation. The total colonic transit time (56 h vs 10 h, P<0.0001) and rectal sensation including urge sensation (79 mL vs 63 mL, P = 0.019) and maximum tolerable volume (110 mL vs95 mL, P = 0.03) differed in patients and controls. Constipated subjects had significantly higher anxiety and depression scores and lower SF-36 scores in all categories. They also demonstrated higher scores of'monitoring' coping strategy (14+6 vs9+3, P = 0.001),which correlated with the rectal distension sensation (P = 0.005), urge sensation (P=0.002), and maximum tolerable volume (P = 0.035). The less use of blunting strategy predicted slow transit constipation in both univariate (P = 0.01) and multivariate analysis (P = 0.03).CONCLUSION: Defective or ineffective use of coping strategies may be an important etiology in functional constipation and subsequently reflected in abnormal anorectal physiology.Annie OO Chan Cecilia Cheng Wai Mo Hui Wayne HC Hu Nina YH Wong KF Lam Wai Man Wong Kam Chuen Lai Shiu Kum Lam Benjamin CY Wong 2005World Journal of Gastroenterology2005,11,34:92
2Serum MicroRNA Signatures Identified in a Genome-Wide Serum MicroRNA Expression Profiling Predict Survival of Non-Small-Cell Lung Cancer(摘要)显示文摘Hu, ZB Chen, X Zhao, Y Tian, T Jin, GF Shu, YQ Chen, YJ Xu, L Zen, K Zhang, CY Shen, HB 2010南京医科大学学报(自然科学版)2010,30,7:141
3Pyogenic liver abscess:An audit of 10 years’experience显示文摘AIM:To describe our own experience with pyogenic liver abscesses over the past 10 years and investigate the risk factors associated with failure of initial percutaneous therapy.METHODS:A retrospective study of records of 63 PLA patients presenting between 1998 and 2008 to Australian tertiary referral centre,were reviewed.Amoebic and hydatid abscesses were excluded.Demographic,clinical,radiological,and microbiological characteristics,as well as surgical/radiological interventions,were recorded.RESULTS:Sixty-three patients(42 males,21 females) aged 65(±14) years[mean±(SD) ]had prodromal symptoms for a median(interquartile range;IQR) of 7(5-14) d.Only 59%of patients were febrile at presentation;however,the serum C-reactive protein was elevated in all 47 in whom it was measured.Liver function tests were non-specifically abnormal.67%of patients had a solitary abscess,while 32%had>3 abscesses with a median(IQR) diameter of 6.3(4-9) cm.Causative organisms were:Streptococcus milleri 25%,Klebsiella pneumoniae 21%,and Escherichia coli 16%.A presumptive cryptogenic cause was most common (34%).Four patients died in this series:one from sepsis,two from advanced cancer,and one from acute myocardial infarction.The initial procedure was radiological aspiration±drainage in 54 and surgery in two patients.17%underwent surgical management during their hospitalization.Serum hypoalbuminaemia[mean (95%CI) :32(29-35) g/L vs 28(25-31) g/L,P=0.045] on presentation was found to be the only factor related to failure of initial percutaneous therapy on univariate analysis.CONCLUSION:PLA is a diagnostic challenge,because the presentation of this condition is non-specific.Intravenous antibiotics and radiological drainage in the first instance allows resolution of most PLAs;However,a small proportion of patients still require surgical drainage.Tony CY Pang Thomas Fung Jaswinder Samra Thomas J Hugh Ross C Smith 2011World Journal of Gastroenterology2011,17,12:46
4Estrogen enhances the functions of CD4^(+)CD25^(+)Foxp3^(+) regulatory T cells that suppress osteoclast differentiation and bone resorption in vitro显示文摘Cross-talk has been shown to occur between the immune system and bone metabolism pathways.In the present study,we investigated the impact of CD4^(+)CD25^(+)Foxp3^(+) regulatory T(Treg)cells on osteoclastogenesis and bone resorption.Treg cells that were isolated and purified from peripheral blood mononuclear cells(PBMCs)of healthy adults inhibited both the differentiation of osteoclasts(OCs)from human embryo bone marrow cells(BMCs)and the pit formation in a dose-dependent manner.In cell cocultures,the production levels of both interleukin-10(IL-10)and transforming growth factor-beta 1(TGF-β1)were proportionally upregulated as the ratio of Treg cells to BMCs was increased,and the inhibition of OC differentiation and bone resorption by Treg cells was completely reversed by anti-IL-10 and anti-TGF-β1 antibodies.Treatment of BMC and Treg cell cocultures with 17β-estradiol(E2)at concentrations between 10^(-7) and 10^(-9) mol/l suppressed OC differentiation and bone resorption more efficiently than it did in cultures of BMCs alone;this enhanced suppression occurred via the stimulation of Treg cell IL-10 and TGF-b1 expression.These data suggest that Treg cells suppress OC differentiation and bone resorption by secreting IL-10 and TGF-β1.E2 enhances the suppressive effects of Treg cells on OC differentiation and bone resorption by stimulating IL-10 and TGF-β1 secretion from these cells.Therefore,Treg cell-derived IL-10 and TGF-b1 are likely involved in the regulation of E2 on bone metabolism and represent potential therapeutic targets for the treatment of postmenopausal osteoporosis(PMO).CY Luo L Wang C Sun DJ Li 2011Cellular & Molecular Immunology2011,8,1:33
5High-intensity focused ultrasound ablation:An effective bridging therapy for hepatocellular carcinoma patients显示文摘AIM:To analyze whether high-intensity focused ultrasound(HIFU) ablation is an effective bridging therapy for patients with hepatocellular carcinoma(HCC).METHODS:From January 2007 to December 2010,49 consecutive HCC patients were listed for liver transplantation(UCSF criteria).The median waiting time for transplantation was 9.5 mo.Twenty-nine patients received transarterial chemoembolization(TACE) as a bringing therapy and 16 patients received no treatment before transplantation.Five patients received HIFU ablation as a bridging therapy.Another five patients with the same tumor staging(within the UCSF criteria) who received HIFU ablation but not on the transplant list were included for comparison.Patients were comparable in terms of Child-Pugh and model for end-stage liver disease scores,tumor size and number,and cause of cirrhosis.RESULTS:The HIFU group and TACE group showed no difference in terms of tumor size and tumor number.One patient in the HIFU group and no patient in the TACE group had gross ascites.The median hospital stay was 1 d(range,1-21 d) in the TACE group and two days(range,1-9 d) in the HIFU group(P < 0.000).No HIFU-related complication occurred.In the HIFU group,nine patients(90%) had complete response and one patient(10%) had partial response to the treatment.In the TACE group,only one patient(3%) had response to the treatment while 14 patients(48%) had stable disease and 14 patients(48%) had progressive disease(P = 0.00).Seven patients in the TACE group and no patient in the HIFU group dropped out from the transplant waiting list(P = 0.559).CONCLUSION:HIFU ablation is safe and effective in the treatment of HCC for patients with advanced cirrhosis.It may reduce the drop-out rate of liver transplant candidate.Tan To Cheung Sheung Tat Fan See Ching Chan Kenneth SH Chok Ferdinand SK Chu Caroline R Jenkins Regina CL Lo James YY Fung Albert CY Chan William W Sharr Simon HY Tsang Wing Chiu Dai Ronnie TP Poon Chung Mau Lo 2013World Journal of Gastroenterology2013,19,20:23
6亚太地区胃食管反流病的处理共识:更新版显示文摘背景与目的:自从2004年亚太地区胃食管反流病(GERD)共识发表以来,更多关于GERD流行病学和处理的文献资料相继出现。有必要对这些资料进行循证综述,对共识作出更新。方法:由多学科专家组应用德尔菲(Delphi)法制定共识条文,提呈相关资料,并对证据质量、推荐力度和共识水平进行分级。结果:亚洲GERD发生率日益增加。其危险因素包括老年、男性、种族、家族史、社会经济地位高、体重指数增加和吸烟。对于有典型症状而无报警症状的患者,对质子泵抑制剂(PPI)试验有症状应答具有诊断意义。如PPI试验失败,停止治疗后pH监测结果阴性可排除GERD。窄带成像、胶囊内镜检查和无线pH监测的作用尚未明确。亚洲诊断策略的制定须考虑到并存的胃癌和消化性溃疡。减轻体质量和抬高床头可改善反流症状。PPIs是最有效的内科治疗手段。对于非糜烂性反流病(NERD)患者,按需治疗较为适宜。有慢性咳嗽、喉炎和典型GERD症状的患者在排除非GERD病因后,应予PPI每天两次治疗。如有经验丰富的外科医师,GERD患者可行胃底折叠术。除临床试验外,GERD不应采用内镜治疗。结论:新的诊断方法和内镜治疗的作用有待进一步研究阐明。亚洲GERD诊断策略的制定须考虑到并存的胃癌和消化性溃疡。PPIs仍为治疗的基石。Kwong Ming Fock Nicholas J Talley Ronnie Fass Khean Lee Goh Peter Katelaris Richard Hunt Michio Hongo Tiing Leong Ang Gerald Holtmann Sanjay Nandurkar San Ren Lin Benjamin CY Wong Francis KL Chan Abdul Aziz Rani Young-Tae Bak Jose Sollano Khek Yu Ho Sathoporn Manatsathit 钱本余 2008胃肠病学2008,13,7:21
7Effects of tachyplesin on the morphology and ultrastructure of human gastric carcinoma cell line BGC-823显示文摘AIM To investigate the morphological andultrastructural changes in the human gastriccarcinoma cell line BGC-823 after being treatedwith tachyplesin.METHODS Tachyplesin was isolated from acidextracts of Chinese horseshoe crab(Tachypleustridentatus)hemocytes.BGC-823 cells and thecells treated with 2.0mg/L tachyplesin wereexamined respectively under light microscope,scanning and transmission electron microscope.RESULTS BGC-823 cells had undergone therestorational alteration in morphology andultrastructure after tachyplesin treatment.Thechanges were as follows:the shape of cells wasunanimous,the volume enlarged and cellsturned to be flat and spread,the nucleo-cytoplasmic ratio lessened and nuclear shapebecame rather regular,the number of nucleolusreduced and its volume lessened,heter-chromatin decreased while euchromatinincreased in nucleus.In the cytoplasm,mitochondria grew in number with consistentstructure relatively,Golgi complex turned to betypical and well-developed,rough endoplasmicreticulum increased and polyribosomedecreased.The microvilli at cellular surfacewere rare and the filopodia reduced whilelamellipodia increased at the cell edge.CONCLUSION Tachyplesin could alter themalignant morphological and ultrastructuralcharacteristics of human gastric carcinoma cellseffectively and have a certain inducing differen-tiation effect on human gastric carcinoma cells.Li QF Ou Yang GL Li CY Hong SG 2000World Journal of Gastroenterology2000,6,5:19

10Treatment of functional dyspepsia with sertraline:A double-blind randomized placebo-controlled pilot study显示文摘AIM:To evaluate sertraline,a selective serotonin reuptake inhibitor in the treatment of patients with functional dyspepsia.METHODS:Consecutive tertiary hospital patients with a clinical diagnosis of functional dyspepsia(FD) according to the Rome Ⅱ criteria with a Hong Kong dyspepsia index(HKDI) of greater than 16 were recruited.Patients commenced enrolment prior to the inception of the Rome Ⅲ criteria for functional dyspepsia.All patients were ethnic Chinese,had a normal upper endoscopy and were Helicobacter pylori negative prior to enrolment.Study patients were randomized to receive sertraline 50 mg or placebo daily for 8 wk.HKDI symptom scores,quality of life,hospital anxiety and depression(HAD) scale and global symptom relief were evaluated before,during and after treatment.Adverse effects were monitored during and after treatment.RESULTS:A total of 193 patients were randomized in the intention to treat(ITT),and 150 patients were included in the per protocol(PP) analysis.In both the ITT and PP,there was no difference in the primary outcome of global dyspepsia symptoms between the sertraline and placebo groups at week 8.In the ITT analysis,98 and 95 patients were randomized to the sertraline and placebo groups respectively.A total of 43 patients withdrew from the study(22.3%) by week 8,with 23 of the 24 drop-outs in the sertraline group occurring prior to week 4(95.8%).In contrast,in the placebo arm,11 of 19 patients dropped out by week 4(57.9%).Utilizing the last response carried forward to account for the drop-outs,there were no differences between the sertraline and placebo groups at baseline in terms of the HKDI,HKDI 26.08 ± 6.19 vs 26.70 ± 5.89,P = 0.433;and at week 8,HKDI 22.41 ± 6.36 vs 23.25 ± 7.30,P = 0.352 respectively.In the PP analysis,74 and 76 patients were randomized to the sertraline and placebo groups respectively.At baseline,there were no statistically significant differences between the sertraline and placebo groups,HKDI 25.83 ± 6.313 vs 27.19 ± 5.929 respectively,P = 0.233;however by week 8,patients in the sertraline group demonstrated a statistically significant difference in their Hong Kong Dyspepsia Index compared to placebo,HKDI 20.53 ± 6.917 vs 23.34 ± 7.199,P = 0.02,respectively).There was also no statistically significant difference in overall quality of life measures or the HAD scale related to treatment in either the ITT or PP analysis at week 8.CONCLUSION:This pilot study,the first to examine sertraline,a selective serotonin reuptake inhibitor,for the management of FD,did not find that it was superior to placebo.Victoria PY Tan Tin K Cheung Wai M Wong Roberta Pang Benjamin CY Wong 2012World Journal of Gastroenterology2012,18,42:14
11miR-182参与调节胶质母细胞瘤的凋亡、生长和分化(英文)显示文摘Glioblastoma multiforme(GBM)is a lethal,therapy-resistant brain cancer consisting of numerous tumor cell subpopulations,including stem-like glioma-initiating cells(GICs),which contribute to tumor recurrence following initial response to therapy.Here,we identified miR-182 as a regulator of apoptosis,growth,and differentiation programs whose expression level is correlated with GBM patient survival.Repression of Bcl2-like12(Bcl2L12),c-Met,and hypoxia-inducible factor 2α(HIF2A)is of central importance to miR-182 anti-tumor activity,as it results in enhanced therapy susceptibility,decreased GIC sphere size,expansion,and stemness in vitro.To evaluate the tumor-suppressive function of miR-182 in vivo,we synthesized miR-182-based spherical nucleic acids(182-SNAs);i.e.,gold nanoparticles covalently functionalized with mature miR-182 duplexes.Intravenously administered 182-SNAs penetrated the bloodbrain/blood-tumor barriers(BBB/BTB)in orthotopic GBM xenografts and selectively disseminated throughout extravascular glioma parenchyma,causing reduced tumor burden and increased animal survival.Our results indicate that harnessing the anti-tumor activities of miR-182 via safe and robust delivery of 182-SNAs represents a novel strategy for therapeutic intervention in GBM.Kouri FM Hurley LA Daniel WL Day ES Hua Y Hao L Peng CY Merkel TJ Queisser MA Ritner C Zhang H James CD Sznajder JI Chin L Giljohann DA Kessler JA Peter ME Mirkin CA Stegh AH 2015中华神经外科疾病研究杂志2015,14,2:14

13Surgical management of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the second most common cause of death from cancer worldwide. Standard potentially curative treatments are either resection or transplantation. The aim of this paper is to provide an overview of the surgical management of HCC, as well as highlight current issues in hepatic resection and transplantation. In summary, due to the relationship between HCC and chronic liver disease, the management of HCC depends both on tumourrelated and hepatic function-related considerations. As such, HCC is currently managed largely through nonsurgical means as the criteria, in relation to the above considerations, for surgical management is still largelyrestrictive. For early stage tumours, both resection and transplantation offer fairly good survival outcomes(5 years overall survival of around 50%). Selection therefore would depend on the level of hepatic function derangement, organ availability and local expertise. Patients with intermediate stage cancers have limited options, with resection being the only potential for cure. Otherwise, locoregional therapy with transarterial chemoembolization or radiofrequency ablation are viable options. Current issues in resection and transplantation are also briefly discussed such as laparoscopic resection, ablation vs resection, anatomical vs non-anatomical resection, transplantation vs resection, living donor liver transplantation and salvage liver transplantation.Tony CY Pang Vincent WT Lam 2015World Journal of Hepatology2015,7,2:10
14Prevention and management of hepatitis B virus reactivation in patients with hematological malignancies treated with anticancer therapy显示文摘Hepatitis due to hepatitis B virus(HBV) reactivation can be severe and potentially fatal, but is preventable. HBV reactivation is most commonly reported in patients receiving cancer chemotherapy, especially rituximabcontaining therapy for hematological malignancies and those receiving stem cell transplantation. All patients with hematological malignancies receiving anticancer therapy should be screened for active or resolved HBV infection by blood tests for hepatitis B surface antigen(HBs Ag) and antibody to hepatitis B core antigen(antiHBc). Patients found to be positive for HBs Ag should be given prophylactic antiviral therapy to prevent HBV reactivation. For patients with resolved HBV infection, no standard strategy has yet been established to prevent HBV reactivation. There are usually two options. One is pre-emptive therapy guided by serial HBV DNA monitoring, whereby antiviral therapy is given as soon as HBV DNA becomes detectable. However, there is little evidence regarding the optimal interval and period of monitoring. An alternative approach is prophylactic antiviral therapy, especially for patients receiving highrisk therapy such as rituximab, newer generation of anti-CD20 monoclonal antibody, obinutuzumab or hematopoietic stem cell transplantation. This strategy may effectively prevent HBV reactivation and avoid the inconvenience of repeated HBV DNA monitoring. Entecavir or tenofovir are preferred over lamivudine as prophylactic therapy. Although there is no well-defined guideline on the optimal duration of prophylactic therapy, there is growing evidence to recommend continuing prophylactic antiviral therapy for at least 12 mo after cessation of chemotherapy, and even longer for those who receive rituximab or who had high serum HBV DNA levels before the start of immunosuppressive therapy. Many novel agents have recently become available for the treatment of hematological malignancies, and these agents may be associated with HBV reactivation. Although there is currently limited evidence to guide the optimal preventive measures, we recommend antiviral prophylaxis in HBs Ag-positive patients receiving novel treatments, especially the Bruton tyrosine kinase inhibitors and the phosphatidylinositol 3-kinase inhibitors, which are B-cell receptor signaling modulators and reduce proliferation of malignant B-cells. Further studies are needed to clarify the risk of HBV reactivation with these agents and the best prophylactic strategy in the era of targeted therapy for hematological malignancies.Man Fai Law Rita Ho Carmen KM Cheung Lydia HP Tam Karen Ma Kent CY So Bonaventure Ip Jacqueline So Jennifer Lai Joyce Ng Tommy HC Tam 2016World Journal of Gastroenterology2016,22,28:10
15Key factors in developing the trinitrobenzene sulfonic acid-induced post-inflammatory irritable bowel syndrome model in rats显示文摘AIM:To investigate the key factors in developing the trinitrobenzene sulfonic acid(TNBS)-induced postinflammatory irritable bowel syndrome(PI-IBS)model in rats. METHODS:TNBS was administered to rats at the following conditions:(1)with different doses(20,10,5 mg/0.8 mL per rat);(2)with same dose in different concentrations(20 mg/rat,25,50 mg/mL);(3)in different ethanol percentage(25%,50%);and(4)at depth either 4 cm or 8 cm from anus.At 5 d and 4 wk after TNBS administration,inflammation severity and inflammation resolution were evaluated.At 4 and 8 wk after TNBS application,visceral hyperalgesia and enterochromaffin(EC)cell hyperplasia were assayed by abdominal withdrawal reflex test,silver staining and capillary electrophoresis. RESULTS:Our results showed that:(1)TNBS induced dose-dependent acute inflammation and inflammation resolution.At 5 d post TNBS,the pathological score and myeloperoxidase(MPO)activity in all TNBS treated rats were significantly elevated compared to that of the control(9.48±1.86,8.18±0.67,5.78± 0.77 vs 0,and 3.55±1.11,1.80±0.82,0.97±0.08 unit/mg vs 0.14±0.01 unit/mg,P<0.05).At 4 wk post TNBS,the pathological score in high and median dose TNBS-treated rats were still significantly higher than that of the control(1.52±0.38 and 0.80±0.35 vs 0,P<0.05);(2)Intracolonic TNBS administration position affected the persistence of visceral hyperalgesia.At 4 wk post TNBS,abdominal withdrawal reflex (AWR)threshold pressure in all TNBS-treated groups were decreased compared to that of the control(21.52 ±1.73 and 27.10±1.94 mmHg vs 34.44±1.89 mmHg,P<0.05).At 8 wk post TNBS,AWR threshold pressure in 8 cm administration group was still significantly decreased(23.33±1.33 mmHg vs 36.79±2.29 mmHg,P<0.05);(3)Ethanol percentage affected the TNBS-induced inflammation severity and visceral hyperalgesia.In TNBS-25%ethanol-treated group,the pathological score and MPO activity were significantly lowered compared to that of the TNBS-50%ethanoltreated group,while AWR threshold pressure were significantly elevated(36.33±0.61 mmHg vs 23.33±1.33 mmHg,P<0.05);and(4)TNBS(5 mg/0.8 mL per rat, in 50%ethanol,8 cm from anus)-treated rats recovered completely from the inflammation with acquired visceral hyperalgesia and EC cell hyperplasia at 4 wk after TNBS administration.CONCLUSION:TNBS dosage,concentration,intraco-lonic administration position,and ethanol percentage play important roles in developing visceral hyperalgesia and EC cell hyperplasia of TNBS-induced PI-IBS rats.Hong-Yan Qin Hai-Tao Xiao Justin CY Wu Brian M Berman Joseph JY Sung Zhao-Xiang Bian 2012World Journal of Gastroenterology2012,18,20:10

19杏仁核-海马环路参与抑郁症的发病机制显示文摘慢性应激常可引发抑郁症。临床资料显示,抑郁症病人的腹侧海马CA1区(vCA1)n体积减小。vCA1是否参与抑郁症的发病?vCA1通过什么环路起作用?其分子机制如何?是本文要回答的科学问题。研究者利用慢性不可预见性温和应激(CUMS),构建小鼠抑郁症模型。主要结果如下:(1)与对照组相比,CUMS组vCA1中表达c-Fos的兴奋性神经元的比例降低。采用化学遗传学方法激活vCA1内兴奋性神经元,可明显缓解抑郁样行为。因此,海马vCA1内兴奋性神经元的活性降低,介导抑郁症的发生。刘风雨(译) Ma H Li CY Wang JP 2021中国疼痛医学杂志2021,27,2:9
20慢性药物性肝损伤生化学未缓解的列线图预测模型的建立显示文摘【据Hepatology 2021年12月报道】题:慢性药物性肝损伤生化学未缓解的列线图预测模型的建立(作者Wang CY等)药物性肝损伤(DILI)已被公认为急性和慢性肝病的重要原因。虽然大多数经历DILI的患者在停用可疑药物后可获得临床和生化学的完全缓解,但仍有8%~20%的患者可进展为慢性DILI。反复出现生化学未缓解(BNR)的DILI患者可能进展至肝硬化甚至肝衰竭,生活质量差。目前慢性DILI的诊断仍然具有很大的挑战性,肝活检虽然有助于DILI诊断的正确性,但其临床应用受到了有创性及高成本的限制。此外,DILI的组织学及生化特征与预后的关系尚不明确。纪冬 WANG CY DENG Y LI P 2022临床肝胆病杂志2022,38,1:8
