4Spider angiomas in patients with liver cirrhosis: Role of vascular endothelial growth factor and basic fibroblast growth factor显示文摘AIM: To investigate whether vascular endothelial growth factor (VEGF) and basic fibroblastic growth factor (bFGF) are associated wibh spider angiomas in patients wibh liver cirrhosis. METHODS: Eighty-six patients with liver cirrhosis were enrolled and the number and size of the spider angiomas were recorded. Fifty-three healthy subjects were selected as controls. Plasma levels of VEGF and bFGF were measured in both the cirrhotics and the controls. RESULTS: Plasma VEGF and bFGF were increased in cirrhotics compared with controls (122±13 vs. 71±11 pg/mL, P=0.003 for VEGF; 5.1±0.5 vs. 3.4±0.5 pg/mL, P=0.022 for bFGF). In cirrhotics, plasma VEGF and bFGF were also higher in patients with spider angiomas compared with patients without spider angiomas (185±28 vs. 90±10 pg/mL, P=-0.003 for VEGF; 6.8±1.0 vs. 4.1±0.5 pg/mL, P=0.017 for bFGF). Multivariate logistic regression showed that young age and increased plasma levels of VEGF and bFGF were the most significant predictors for the presence of spider angiomas in cirrhotic patients (odds ratio [OR]=6.64, 95% confidence interval[CI]=2.02-21.79, P=0.002; OR=4.35, 95% CI=1.35-14.01,P=0.014; OR=5.66, 95% CI=1.72-18.63, P=0.004, respectively). CONCLUSION: Plasma VEGF and bFGF are elevated inpatients with liver cirrhosis. Age as well as plasma levels of VEGF and bFGF are significant predictors for spider angiomas in cirrhotic patients.Chun-Pin Li Fa-Yauh Lee Shinn-Jang Hwang Rei-Hwa Lu Wei-Ping Lee Yee Chao Sung-Sang Wang Full-Young Chang Jacqueline Whang-Peng Shou-Dong Lee 2003World Journal of Gastroenterology2003,9,12:24

7基于主根横断面近红外光谱的西洋参和人参鉴别研究显示文摘为了快速准确进行西洋参和人参的品种鉴别,从主根横断面入手,采集其横断面的近红外光谱,分别从物理结构因素和化学因素方面对光谱进行了分析,选定特定波段进行物理因素主导建模、化学因素主导建模、理化因素综合建模,并对三种建模结果进行比较分析,发现三种模型判别率都在96%以上,都能很好的满足批量原材料快速检测的需求。物理因素模型运算简单,但判别率相对低。化学因素判别率较高,但运算量大。理化因素综合模型判别率最高为100%,无需预处理,运算量小,效果最理想,该结果说明近红外定性判别中物理结构因素有时也发挥重要作用。横断面鉴别法准确、便捷,可实际应用于企业原料药材的质量控制,实现对原料药材的快速筛查。王灵灵 黄亚伟 戚淑叶 Jacqueline J SHAN Lei LING 韩东海 2012光谱学与光谱分析2012,32,4:17
8重症监护与非重症监护患者的压力性损伤患病率:全州范围的比较显示文摘背景:医院获得性压力性损伤(HAPI)与患病率和病死率的增加有关,被认为在很大程度上是可以预防的。压力性损伤的患病率被视为反映卫生保健质量的一项指标。目的:在全州范围内,比较重症监护室(ICU)患者和非ICU患者的压力性损伤的患病率、严重程度和发生部位。方法 :本研究采用二次数据分析设计,从昆士兰州所有拥有Ⅰ-Ⅲ级重症监护室,并参与了2012-2014年昆士兰床旁审计的卫生医院,提取和分析去识别化处理的压力性损伤数据。样本涵盖所有成人ICU患者和非ICU患者,患者均同意参与昆士兰床旁审计。精神卫生单位除外。结果 :除压力性损伤Ⅰ期外,2012-2014年间,ICU患者HAPI的总患病率为11%,非ICU患者为3%;住院期间,ICU患者发展为压力性损伤的可能性是非ICU患者的3.8倍(RR的95%可信区间为2.7~5.4)。对所有患者来说,骶骨/尾骨都是HAPI最常见的部位(ICU患者为22%,非ICU患者为35%)。然而,ICU患者黏膜压力性损伤的比例(22%)显著高于非ICU患者(2%)。压力性损伤Ⅱ期是HAPI患病率最高的阶段,ICU患者为53%,非ICU患者为63%。Fiona Coyer Sandra Miles Sandra Gosley Paul Fulbrook Kirstine Sketcher-Baker Jane-Louise Cook Jacqueline Whitmore 2017中国护理管理2017,17,9:17
9Probiotic effects on intestinal fermentation patterns in patients with irritable bowel syndrome显示文摘AIM: To determine whether Lactobacillus casei strain Shirota (Yakult ) can alter small intestinal bacterial overgrowth (SIBO), as tested by the lactulose breath test, and whether this is associated with changes in symptoms in irritable bowel syndrome (IBS). METHODS: 18 patients with IBS (Rome Ⅱ criteria), who showed an early rise in breath hydrogen with lactulose (ERBHAL), consumed 65 mL of Yakult daily for 6 wk. Lactulose breath test was repeated at the end of the treatment period. Symptoms were recorded daily using a 10 cm visual analogue scale. RESULTS: 14 patients completed the study, 9 (64%) had reversal of ERBHAL, with the median time of f irst rise in breath hydrogen increasing from 45 to 75 min (P = 0.03). There was no signifi cant improvement in the symptom score with probiotic therapy, except for wind (P=0.04). Patients commencing with at least moderate symptoms and who no longer had ERBHAL at the end of treatment, showed improvement in the overall symptoms scores [median fi nal score 5.3 (IQR3.9-5.9), 55% reduction; n=6] to a greater extent than those who had had persisting ERBHAL [final score 6.9 (5.0-7.0), 12% reduction; n = 5; P = 0.18]. CONCLUSION: Yakult is effective in altering fermentation patterns in the small bowel, consistent with reducing SIBO. The loss of ERBHAL was associated with reduced symptoms. The true interpretation of these fi ndings awaits a randomised, controlled trial.Jacqueline S Barrett Kim EK Canale Richard B Gearry Peter M Irving Peter R Gibson 2008World Journal of Gastroenterology2008,14,32:16
10Encapsulating peritoneal sclerosis显示文摘Encapsulating peritoneal sclerosis(EPS) is a debilitating condition characterized by a fibrocollagenous membrane encasing the small intestine, resulting in recurrent small bowel obstructions. EPS is most commonly associated with long-term peritoneal dialysis, though medications, peritoneal infection, and systemic inflammatory disorders have been implicated. Many cases remain idiopathic. Diagnosis is often delayed given the rarity of the disorder combined with non-specific symptoms and laboratory findings. Although cross-sectional imaging with computed tomography of the abdomen can be suggestive of the disorder, many patients undergo exploratory laparotomy for diagnosis. Mortality approaches 50% one year after diagnosis. Treatment for EPS involves treating the underlying condition or eliminating possible inciting agents(i.e. peritoneal dialysis, medications, infections) and nutritional support, frequently with total parenteral nutrition. EPSspecific treatment depends on the disease stage. In the inflammatory stage, corticosteroids are the treatment of choice, while in the fibrotic stage, tamoxifen may be beneficial. In practice, distinguishing between stages may be difficult and both may be used. Surgical intervention, consisting of peritonectomy and enterolysis, is timeconsuming and high-risk and is reserved for situations in which conservative medical therapy fails in institutions with surgical expertise in this area. Herein we review the available literature of the etiology, pathogenesis, diagnosis, and treatment of this rare, but potentially devastating disease.Christopher J Danford Steven C Lin Martin P Smith Jacqueline L Wolf 2018World Journal of Gastroenterology2018,24,28:13

13Does playing a sports active video game improve object control skills of children with autism spectrum disorder?显示文摘Background: Active video games(AVGs) encourage whole body movements to interact or control the gaming system, allowing the opportunity for skill development. Children with autism spectrum disorder(ASD) show decreased fundamental movement skills in comparison with their typically developing(TD) peers and might benefit from this approach. This pilot study investigates whether playing sports AVGs can increase the actual and perceived object control(OC) skills of 11 children with ASD aged 6–10 years in comparison to 19 TD children of a similar age.Feasibility was a secondary aim.Methods: Actual(Test of Gross Motor Development) and perceived OC skills(Pictorial Scale of Perceived Movement Skill Competence for Young Children) were assessed before and after the intervention(6 × 45 min).Results: Actual skill scores were not improved in either group. The ASD group improved in perceived skill. All children completed the required dose and parents reported the intervention was feasible.Conclusion: The use of AVGs as a play-based intervention may not provide enough opportunity for children to perform the correct movement patterns to influence skill. However, play of such games may influence perceptions of skill ability in children with ASD, which could improve motivation to participate in physical activities.Jacqueline Edwards Sarah Jeffrey Tamara May Nicole J.Rinehart Lisa M.Barnett 2017Journal of Sport and Health Science2017,6,1:12
14Diabetes and cancer:Looking at the multiligand/RAGE axis显示文摘The association between diabetes and hyperglycemia and the associated increased risk of several solid and hematologic malignancies has been the subject of investigation for many years.Although the association is not fully understood,current knowledge clearly indicates that diabetes may influence malignant cell transformation by several mechanisms,including hyperinsulinemia,hyperglycemia and chronic inflammation.In this context,the receptor for advanced glycation end-products (RAGE) has emerged as a focal point in its contribution to malignant transformation and tumor growth.We high-light how RAGE,once activated,as it manifests itself in conditions such as diabetes or hyperglycemia,is able to continuously bring about an inflammatory milieu,thus supporting the contribution of chronic inflammation to the development of malignancies.Armando Rojas Ileana González Erik Morales Ramón Pérez-Castro Jacqueline Romero Héctor Figueroa 2011World Journal of Diabetes2011,2,7:11
15Indoleamine 2,3-dioxygenase (IDO) is essential for dendritic cell activation and chemotactic responsiveness to chemokines显示文摘Indoleamine 2, 3-dioxygenase (IDO) is a rate-limiting enzyme for the tryptophan catabolism. In human and murine cells, IDO inhibits antigen-specific T cell proliferation in vitro and suppresses T cell responses to fetal alloantigens during murine pregnancy. In mice, IDO expression is an inducible feature of specific subsets of dendritic cells (DCs), and is important for T cell regulatory properties. However, the effect of IDO and tryptophan deprivation on DC func- tions remains unknown. We report here that when tryptophan utilization was prevented by a pharmacological inhibitor of IDO, 1-methyl tryptophan (1MT), DC activation induced by pathogenic stimulus lipopolysaccharide (LPS) or inflam- matory cytokine TNF-α was inhibited both phenotypically and functionally. Such an effect was less remarkable when DC was stimulated by a physiological stimulus, CD40 ligand. Tryptophan deprivation during DC activation also regu- lated the expression of CCR5 and CXCR4, as well as DC responsiveness to chemokines. These results suggest that tryptophan usage in the microenvironment is essential for DC maturation, and may also play a role in the regulation of DC migratory behaviors.Shih Ling HWANG Nancy Pei-Yee CHUNG Jacqueline Kwai-Yi CHAN Chen-Lung Steve LIN 2005Cell Research2005,15,3:11

17A new prognostic histopathologic classification of nasopharyngeal carcinoma显示文摘Background:The current World Health Organization(WHO) classification of nasopharyngeal carcinoma(NPC) con?veys little prognostic information.This study aimed to propose an NPC histopathologic classification that can poten?tially be used to predict prognosis and treatment response.Methods:We initially developed a histopathologic classification based on the morphologic traits and cell differentia?tion of tumors of 2716 NPC patients who were identified at Sun Yat?sen University Cancer Center(SYSUCC)(training cohort).Then,the proposed classification was applied to 1702 patients(retrospective validation cohort) from hospitals outside SYSUCC and 1613 patients(prospective validation cohort) from SYSUCC.The efficacy of radiochemotherapy and radiotherapy modalities was compared between the proposed subtypes.We used Cox proportional hazards models to estimate hazard ratios(HRs) with 95% confidence intervals(CI) for overall survival(OS).Results:The 5?year OS rates for all NPC patients who were diagnosed with epithelial carcinoma(EC;3708 patients),mixed sarcomatoid?epithelial carcinoma(MSEC;1247 patients),sarcomatoid carcinoma(SC;823 patients),and squamous cell carcinoma(SCC;253 patients) were 79.4%,70.5%,59.6%,and 42.6%,respectively(P < 0.001).In mul?tivariate models,patients with MSEC had a shorter OS than patients with EC(HR = 1.44,95% CI = 1.27–1.62),SC(HR = 2.00,95% CI = 1.76–2.28),or SCC(HR = 4.23,95% CI = 3.34–5.38).Radiochemotherapy significantly improved survival compared with radiotherapy alone for patients with EC(HR 49–0.75),and possibly for those with SCC(HR = 0.67,95% CI = 0.56–0.80),MSEC(HR = 0.58,95% CI = 0..74–1.28).= 0.63;95% CI = 0.40–0.98),but not for patients with SC(HR = 0.97,95% CI = 0Conclusions:The proposed classification offers more information for the prediction of NPC prognosis compared with the WHO classification and might be a valuable tool to guide treatment decisions for subtypes that are associ?ated with a poor prognosis.Hai-Yun Wang Yih-Leong Chang Ka-Fai To Jacqueline S.G.Hwang Hai-Qiang Mai Yan-Fen Feng Ellen T.Chang Chen-Ping Wang Michael Koon Ming Kam Shie-Lee Cheah Ming Lee Li Gao Hui-Zhong Zhang Jie-Hua He Hao Jiang Pei-Qing Ma Xiao-Dong Zhu Liang Zeng Chun-Yan Chen Gang Chen Ma-Yan Huang Sha Fu Qiong Shao An-Jia Han Hai-Gang Li Chun-Kui Shao Pei-Yu Huang Chao-Nan Qian Tai-Xiang Lu Jin-Tian Li Weimin Ye Ingemar Ernberg Ho Keung Ng Joseph T.S.Wee Yi-Xin Zeng Hans-Olov Adami Anthony T.C.Chan Jian-Yong Shao 2016Chinese Journal of Cancer2016,35,6:10
18Prevention 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
19Optical coherence tomography angiography for the anterior segment显示文摘Optical coherence tomography angiography(OCTA)is a rapid and non-invasive technique for imaging vasculature in the eye.As OCTA can produce high-resolution cross-sectional images and allow depth-resolved analysis for accurate localization of pathology of interest,it has become a promising method for anterior segment imaging.Furthermore,OCTA offers a more patient-friendly alternative to the conventional invasive dye-based fluorescent angiography.However,conventional OCTA systems are typically designed and optimized for the posterior segment of the eye,and thus using OCTA for anterior segment imaging can present several difficulties and limitations.In this review,we summarized the recent developments and clinical applications in anterior segment OCTA(AS-OCTA)imaging,such as for the cornea,iris,sclera and conjunctiva.We also compared commercially available OCTA systems,discussed the limitations of adapting current OCTA technology for the anterior segment imaging,and proposed possible future directions for AS-OCTA systems.AS-OCTA provides potential for future clinical applications such as diagnosis of corneal and iris pathologies,pre-operative surgical planning,assessment of new antiangiogenic therapeutics or evaluation of limbal stem cell deficiency.With further development,OCTA for anterior segment imaging in the clinics may become common in the near future.Wen Di Lee Kavya Devarajan Jacqueline Chua Leopold Schmetterer Jodhbir S.Mehta Marcus Ang 2019Eye and Vision2019,6,1:9
20Long-term hepatic consequences of chemotherapy-related HBV reactivation in lymphoma patients显示文摘AIM: To investigate the long-term consequences of chemotherapy-related HBV reactivation in patients with lymphoma.METHODS: This study was based on the database of published prospective study evaluating HBV reactivation in HBV lymphoma patients during chemotherapy.Deteriorated liver reserve (DLR) was defined as development of either one of the following conditions during follow-up: (1) newly onset parenchyma liver disease, splenomegaly or ascites without evidence of lymphoma involvement; (2) decrease of the ratio (albumin/globulin ratio) to less than 0.8 or increase of the ratio of INR of prothrombin time to larger than 1.2 without evidence of malnutrition or infection. Liver cirrhosis was diagnosed by imaging studies.RESULTS: A total of 49 patients were included. The median follow-up was 6.2 years (range, 3.9-8.1 years).There were 31 patients with and 18 patients without HBV reactivation. Although there was no difference of overall survival (OS) and chemotherapy response rate between the two groups, DLR developed more frequently in patients with HBV reactivation (48.4% vs 16.7%; P= 0.0342). Among the HBV reactivators, HBV genotype C was associated with a higher risk of developing DLR (P = 0.0768) and liver cirrhosis (P = 0.003). Four of five patients with sustained high titer of HBV DNA and two of three patients with multiple HBV reactivation developed DLR. Further, patients with a sustained high titer of HBV DNA had the shortest OS among the HBV reactivators (P= 0.0000). No patients in the non-HBV reactivation group developed hepatic failure or liver cirrhosis.CONCLUSION: Chemotherapy-related HBV reactivation is associated with the long-term effect of deterioration of hepatic function.Chi-Chung Wen Chao A.Hsiung Ih-Jen Su Ann-Lii Cheng Ming-Chih Chang Chao-Jung Tsao Woei-Yao Kao Wu-Ching Uen Chiun Hsu Chih-Hung Hsu Yen-Shen Lu Hwei-Fan Tien Tsu-Yi Chao Li-Tzong Chen Jacqueline Whang-Peng Pei-Jer Chen 2005World Journal of Gastroenterology2005,11,34:8
