| 1 | Neoadjuvant radiotherapy for rectal cancer management显示文摘Thirty per cent of all colorectal tumours develop in the rectum.The location of the rectum within the bony pelvis and its proximity to vital structures presents significant therapeutic challenges when considering neoadjuvant options and surgical interventions.Most patients with early rectal cancer can be adequately managed by surgery alone.However,a significant proportion of patients with rectal cancer present with locally advanced disease and will potentially benefit from down staging prior to surgery.Neoadjuvant therapy involves a variety of options including radiotherapy,chemotherapy used alone or in combination.Neoadjuvant radiotherapy in rectal cancer has been shown to be effective in reducing tumour burden in advance of curative surgery.The gold standard surgical rectal cancer management aims to achieve surgical removal of the tumour and all draining lymph nodes,within an intact mesorectal package,in order to minimise local recurrence.It is critically important that all rectal cancer cases are discussed at a multidisciplinary meeting represented by all relevant specialties.Pre-operative staging including CT thorax,abdomen,pelvis to assess for distal disease and magnetic resonance imaging to assess local involvement is essential.Staging radiology and MDT discussion are integral in identifying patients who require neoadjuvant radiotherapy.While Neoadjuvant radiotherapy is potentially beneficial it may also result in morbidity and thus should be reserved for those patients who are at a high risk of local failure,which includes patients with nodal involvement,extramural venous invasion and threatened circumferential margin.The aim of this review is to discuss the role of neoadjuvant radiotherapy in the management of rectal cancer. | Gerard Feeney Rishabh Sehgal Margaret Sheehan Aisling Hogan Mark Regan Myles Joyce Michael Kerin | 2019 | World Journal of Gastroenterology2019，25，33： | 28 |

| 5 | Intracellular signaling mechanisms regulating the activation of human eosinophils by the novel Th2 cytokine IL-33:implications for allergic inflammation显示文摘The novel interleukin(IL)-1 family cytokine IL-33 has been shown to activate T helper 2(Th2)lymphocytes,mast cells and basophils to produce an array of proinflammatory cytokines,as well as to mediate blood eosinophilia,IgE secretion and hypertrophy of airway epithelium in mice.In the present study,we characterized the activation of human eosinophils by IL-33,and investigated the underlying intracellular signaling mechanisms.IL-33 markedly enhanced eosinophil survival and upregulated cell surface expression of the adhesion molecule intercellular adhesion molecule(ICAM)-1 on eosinophils,but it suppressed that of ICAM-3 and L-selectin.In addition,IL-33 mediates significant release of the proinflammatory cytokine IL-6 and the chemokines CXCL8 and CCL2.We found that IL33-mediated enhancement of survival,induction of adhesion molecules,and release of cytokines and chemokines were differentially regulated by activation of the nuclear factor(NF)-KB,p38 mitogen-activated protein kinase(MAPK)and extracellular signal-regulated kinase(ERK)pathways.Furthermore,we compared the above IL-33 activities with two structurally and functionally related cytokines,IL-1 B and IL-18.IL-1β,but not IL-18,markedly upregulated cell surface expression of ICAM-1.IL-1βand IL-18 also significantly enhanced eosinophil survival,and induced the release of IL-6 and chemokines CXCL8 and CCL2 via the activation of the NF-κB,p38 MAPK and ERK pathways.Synergistic efects on the release of IL-6 were also observed in combined treatment withIL-1B,IL-18 and IL-33.Taken together,our findings provide insight into IL-33-mediated activation of eosinophils via differential intracellular signaling cascades in the immunopathogenesis of allergic inflammation. | Joyce YS Chow Chun K Wong Phyllis FY Cheung Christopher WK Lam | 2010 | Cellular & Molecular Immunology2010，7，1： | 22 |

| 8 | Ultrasound shear wave elastography and liver fibrosis: A Prospective Multicenter Study显示文摘AIM To assess the accuracy of shear wave elastography(SWE) alone and in combination with aminotransferase platelet ratio index(APRI) score in the staging of liver fibrosis.METHODS A multicenter prospective study was conducted to assess the accuracy of SWE(medians) and APRI to predict biopsy results. The analysis focused on distinguishing the different stages of liver disease, namely, F0 from F1-4, F0-1 from F2-4, F0-2 from F3-4 and F0-3 from F4; F0-F1 from F2-F4 being of primary interest. The area under the receiver operating characteristic(AUROC) curve was computed using logistic regression model. The role of age, gender and steatosis was also assessed.RESULTS SWE alone accurately distinguished F0-1 from F2-4 with a high probability. The AUROC using SWE alone was 0.91 compared to 0.78 for using the APRI score alone.The APRI score, when used in conjunction with SWE, did not make a significant contribution to the AUROC. SWE and steatosis were the only significant predictors that differentiated F0-1 from F2-4 with an AUROC of 0.944.CONCLUSION Our study validates the use of SWE in the diagnosis and staging of liver fibrosis. Furthermore, the probability of a correct diagnosis is significantly enhanced with the addition of steatosis as a prognostic factor. | Joyce Anyona Sande Suleman Verjee Sudhir Vinayak Farin Amersi Munir Ghesani | 2017 | World Journal of Hepatology2017，9，1： | 16 |

| 10 | Prevention 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 | 2016 | World Journal of Gastroenterology2016，22，28： | 10 |

| 13 | Exosomes:Small vesicles with big roles in cancer,vaccine development,and therapeutics显示文摘Cancer is a deadly disease that is globally and consistently one of the leading causes of mortality every year.Despite the availability of chemotherapy,radiotherapy,immunotherapy,and surgery,a cure for cancer has not been attained.Recently,exosomes have gained significant attention due to the therapeutic potential of their various components including proteins,lipids,nucleic acids,miRNAs,and lncRNAs.Exosomes constitute a set of tiny extracellular vesicles with an approximate diameter of 30-100 nm.They are released from different cells and are present in biofluids including blood,cerebrospinal fluid(CSF),and urine.They perform crucial multifaceted functions in the malignant progression of cancer via autocrine,paracrine,and endocrine communications.The ability of exosomes to carry different cargoes including drug and molecular information to recipient cells make them a novel tool for cancer therapeutics.In this review,we discuss the major components of exosomes and their role in cancer progression.We also review important literature about the potential role of exosomes as vaccines and delivery carriers in the context of cancer therapeutics. | Abhimanyu Thakur Diana Carolina Parra Pedram Motallebnejad Marcelo Brocchi Huanhuan Joyce Chen | 2022 | Bioactive Materials2022，7，4： | 8 |

| 15 | Endoscopic balloon catheter dilatation via retrograde or static technique is safe and effective for cricopharyngeal dysfunction显示文摘AIM To evaluate the safety and efficacy of upper esophageal sphincter(UES) dilatation for cricopharyngeal(CP) dysfunction. To determine if:(1) indication for dilatation; or(2) technique of dilatation correlated with symptom improvement.METHODS All balloon dilatations performed at our institution from over a 3-year period were retrospectively analyzed for demographics, indication and dilatation site. All dilatations involving the UES underwent further review to determine efficacy, complications, and factors that predict success. Dilatation technique was separated into static(stationary balloon distention) and retrograde(brusque pull-back of a fully distended balloon across the UES).RESULTS Four hundred and eighty-eight dilatations were reviewed. Thirty-one patients were identified who underwent UES dilatation. Median age was 63 years(range 27-81)and 55% of patients were male. Indications included dysphagia(28 patients), globus sensation with evidence of UES dysfunction(2 patients) and obstruction to echocardiography probe with cricopharyngeal(CP)bar(1 patient). There was evidence of concurrent oropharyngeal dysfunction in 16 patients(52%) and a small Zenker's diverticula(≤ 2 cm) in 7 patients(23%). Dilator size ranged from 15 mm to 20 mm. Of the 31 patients, 11 had dilatation of other esophageal segments concurrently with UES dilatation and 20 had UES dilatation alone.Follow-up was available for 24 patients for a median of 2.5 mo(interquartile range 1-10 mo), of whom 19 reported symptomatic improvement(79%). For patients undergoing UES dilatation alone, follow-up was available for 15 patients, 12 of whom reported improvement(80%).Nineteen patients underwent retrograde dilatation(84%response) while 5 patients had static dilatation(60%response); however, there was no significant difference in symptom improvement between the techniques(P = 0.5).Successful symptom resolution was also not significantly affected by dilator size, oropharyngeal dysfunction,Zenker's diverticulum, age or gender(P > 0.05). The only complication noted was uvular edema and a shallow ulcer after static dilatation in one patient, which resolved spontaneously and did not require hospital admission.CONCLUSION UES dilatation with a through-the-scope balloon by either static or retrograde technique is safe and effective for the treatment of dysphagia due to CP dysfunction. To our knowledge, this is the first study evaluating retrograde balloon dilatation of the UES. | Vinay Chandrasekhara Joyce Koh Lakshmi Lattimer Kerry B Dunbar William J Ravich John O Clarke | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，4： | 6 |
| 16 | 套式PCR检测中国江苏省猪场猪鼻支原体和猪肺炎支原体的感染(英文)显示文摘目的猪鼻支原体和猪肺炎支原体的感染在中国养猪业较为普遍,本研究对江苏省猪鼻支原体(Mycoplasma hyorhinis,Mhr)和猪肺炎支原体(Mycoplasma hyopneumoniae,Mhp)流行病学进行初步调查。方法从江苏省不同的猪场采集7、14、21、28及35日龄仔猪的鼻拭子样本,用套式PCR方法对收集的399份鼻拭子样本进行Mhr和Mhp的检测。结果江苏省不同猪场样本中Mhr的检出率为70.9%,Mhp检出率为13.5%。5周龄以下的猪Mhr的感染率要高于Mhp。其中30个样本(7.5%)的检测结果为两种病原体共感染。7-35日龄的猪Mhr的感染率随着日龄的增长呈现明显的上升趋势,但Mhp的感染率并未随着仔猪日龄的增长而显著上升。从本研究结果分析还发现,不同品种的猪Mhr的感染率存在显著差异,与其他品种猪相比姜曲海瘦肉型品种猪(Jiangquhai porcine lean strain,JQHPL)更易于感染Mhr(p<0.001),但是其Mhp的感染率与其他猪相比不存在显著性差异(P>0.05)。结论本试验调查了江苏地区猪场中仔猪感染Mhr和Mhp的情况,且研究结果表明Mhr的感染状况与日龄及品种有一定关系。 | Joyce Wanjiru Maingi 熊祺琰 韦艳娜 马庆红 纪燕 William Kimaru 华立忠 王佳 邵国青 鲍恩东 | 2014 | 中国人兽共患病学报2014，30，8： | 6 |
| 17 | Current concepts in total femoral replacement显示文摘Total femoral replacement(TFR) is a salvage arthroplasty procedure used as an alternative to lower limb amputation. Since its initial description in the mid-20^(th) century, this procedure has been used in a variety of oncologic and non-oncologic indications. The most compelling advantage of TFR is the achievement of immediate fixation which permits early mobilization. It is anticipated that TFR will be increasingly performed as the rate of revision arthroplasty rises worldwide. The existing literature is mainly composed of a rather heterogeneous mix of retrospective case series and a wide assortment of case reports. Numerous TFR prostheses are currently available and the surgeon must understand the unique implications of each implant design. Long-term functional outcomes are dependent on adherence to proper technique and an appropriate physical therapy program for postoperative rehabilitation. Revision TFR is mainly performed for periprosthetic infection and the severe femoral bone loss associated with aseptic revisions. Depending on the likelihood of attaining infection clearance, it may sometimes be advisable to proceed directly to hip disarticulation without attempting salvage of the TFR. Other reported complications of TFR include hip joint instability, limb length discrepancy, device failure, component loosening, patellar maltracking and delayed wound healing. Further research is needed to better characterize the long-term functional outcomes and complications associated with this complex procedure. | Deepak Ramanathan Marcelo BP Siqueira Alison K Klika Carlos A Higuera Wael K Barsoum Michael J Joyce | 2015 | World Journal of Orthopedics2015，6，11： | 6 |
