1上海26万妇女乳房自我检查随机试验显示文摘目的论证指导妇女进行乳房自我检查(BSE)是否能有效降低乳腺癌患者的死亡率。方法自1989年10月起,上海26.6万名年龄在30~64岁的妇女,随机进入指导组(132979名)和对照组(133085名)。在指导组,最初先由医务人员做规范的BSE手法演示,随后的4年中,使用BSE录像带进行二次强化教育,并定期进行BSE指导和在医务人员监察下进行BSE操作。本研究进行5年,全部活动均被记录。队列人群随访到2000年7月,乳腺癌患者的生存状况随访到2001年12月。统计分析采用Kaplan-Meier方法、Logrank检验以及Cox模型。结果指导组检出乳腺癌864例,其中死于乳腺癌133例;对照组检出乳腺癌896例,其中死于乳腺癌130例。两组乳腺癌病例的肿块大小、TNM分期和累积死亡率的差异均无统计学意义(P均>0.05)。但是指导组比对照组有较多和较小的纤维腺瘤被检出(P<0.01)。结论对人群开展BSE教育和指导,未能降低人群的乳腺癌死亡率;接受BSE教育的妇女比没有接受教育的妇女可检出较多的和较小的良性乳房肿块。高道利 David BThomas Roberta M Ray 王文婉 Charlene J Allison 陈范良 Peggy Porter 胡永伟 赵关林 潘雷达 李雯瑾 武春园 Zakia Coriaty Ilonka Evans 林明纲 Helge Stalsberg Steven Gself 2005中华肿瘤杂志2005,27,6:14
2Treatment 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
3Moving forward in the treatment of cholangiocarcinoma显示文摘Despite being the second most frequent primary liver tumor in humans,early diagnosis and treatment of cholangiocarcinoma(CCA)are still unsatisfactory.In fact,survival after 5 years is expected in less than one fourth of patients diagnosed with this disease.Rare incidence,late appearance of symptoms and heterogeneous biology are all factors contributing to our limited knowledge of this cancer and determining its poor prognosis in the clinical setting.Several efforts have been made in the last decades in order to achieve an improved classification/understanding with regard to the diverse CCA forms.Location within the biliary tree has helped to distinguish between intrahepatic,perihilar and distal CCA types.Sequence analysis contributed to identifying several characteristic genetic aberrations in CCA that may also serve as possible targets for therapy.Novel findings are expected to significantly improve the management of this malignancy in the near future.In this changing scenario our review focuses on the current and future strategies for CCA treatment.Both systemic and surgical treatments are discussed in detail.The results of the main studies in this field are reported,together with the ongoing trials.The current findings suggest that an integrated multidisciplinary approach to this malignancy would be helpful to improve its outcome.Tommaso M Manzia Alessandro Parente Ilaria Lenci Bruno Sensi Martina Milana Carlo Gazia Alessandro Signorello Roberta Angelico Giuseppe Grassi Giuseppe Tisone Leonardo Baiocchi 2021World Journal of Gastrointestinal Oncology2021,13,12:6
4Transcranial direct current stimulation in psychiatric disorders显示文摘The interest in non-invasive brain stimulation techniques is increasing in recent years. Among these techniques, transcranial direct current stimulation(t DCS) has been the subject of great interest among researchers because of its easiness to use, low cost, benign profile of side effects and encouraging results of research in the field. This interest has generated several studies and randomized clinical trials, particularly in psychiatry. In this review, we provide a summary of the development of the technique and its mechanism of action as well as a review of the methodological aspects of randomized clinical trials in psychiatry, including studies in affective disorders, schizophrenia, obsessive compulsive disorder, child psychiatry and substance use disorder. Finally,we provide an overview of t DCS use in cognitive enhancement as well as a discussion regarding its clinical use and regulatory and ethical issues. Although many promising results regarding t DCS efficacy were described, the total number of studies is still low, highlighting the need of further studies aiming to replicate these findings in larger samples as to provide a definite picture regarding t DCS efficacy in psychiatry.Gabriel Tortella Roberta Casati Luana V M Aparicio Antonio Mantovani Natasha Senco Giordano D’Urso Jerome Brunelin Fabiana Guarienti Priscila Mara Lorencini Selingardi Débora Muszkat Bernardo de Sampaio Pereira Junior Leandro Valiengo Adriano H Moffa Marcel Simis Lucas Borrione André R Brunoni 2015World Journal of Psychiatry2015,5,1:6
5Effects of probiotic bacteria on gastrointestinal motility in guinea-pig isolated tissue显示文摘AIM: To evaluate the intestinal motility changes evoked by 8 bacterial strains belonging to Bifidobacterium , Lactobacillus and Streptococcus genera within the probiotic preparation VSL#3. METHODS: Ileum and proximal colon segments isolated from guinea-pigs were used as a study model. Entire cells and cell fractions (cell debris, cell wall fraction, cytoplasmatic fraction, proteinaceous and non- proteinaceous cytoplasmatic components) of VSL#3 strains and, as controls, Escherichia coli, Salmonella aboni and Bacillus licheniformis were tested in this in vitro model. RESULTS: Among the bacterial cell fractions tested, only the cytoplasmatic fraction modified intestinal motility. Lactobacillus strains stimulated the contraction of ileum segment, whereas all probiotic strains tested induced proximal colon relaxation response. The non-proteinaceous cytoplasmatic components were responsible for the colon relaxation. CONCLUSION: The results obtained in this study suggest that the proximal colon relaxation activity showed by the probiotic bacteria could be one of the possible mechanisms of action by which probiotics exert their positive effects in regulating intestinal motility.Matteo Massi Pierfranco Ioan Roberta Budriesi Alberto Chiarini Beatrice Vitali Karen M Lammers Paolo Gionchetti Massimo Campieri Anthony Lembo Patrizia Brigidi 2006World Journal of Gastroenterology2006,12,37:3
6Chronic rejection after liver transplantation:Opening the Pandora’s box显示文摘Chronic rejection(CR)of liver allografts causes damage to intrahepatic vessels and bile ducts and may lead to graft failure after liver transplantation.Although its prevalence has declined steadily with the introduction of potent immunosuppressive therapy,CR still represents an important cause of graft injury,which might be irreversible,leading to graft loss requiring re-transplantation.To date,we still do not fully appreciate the mechanisms underlying this process.In addition to T cell-mediated CR,which was initially the only recognized type of CR,recently a new form of liver allograft CR,antibody-mediated CR,has been identified.This has indeed opened an era of thriving research and renewed interest in the field.Liver biopsy is needed for a definitive diagnosis of CR,but current research is aiming to identify new non-invasive tools for predicting patients at risk for CR after liver transplantation.Moreover,the minimization or withdrawal of immunosuppressive therapy might influence the establishment of subclinical CR-related injury,which should not be disregarded.Therapies for CR may only be effective in the“early”phases,and a tailored management of the immunosuppression regimen is essential for preventing irreversible liver damage.Herein,we provide an overview of the current knowledge and research on CR,focusing on early detection,identification of non-invasive biomarkers,immunosuppressive management,re-transplantation and future perspectives of CR.Roberta Angelico Bruno Sensi Tommaso M Manzia Giuseppe Tisone Giuseppe Grassi Alessandro Signorello Martina Milana Ilaria Lenci Leonardo Baiocchi 2021World Journal of Gastroenterology2021,27,45:2
