1入侵植物喜旱莲子草——生物学、生态学及管理显示文摘喜旱莲子草Alternanthera philoxeroides原产于南美洲,属于苋科Amaranthaceae莲子草属Alternanthera。一百多年来,该物种通过压舱水或军马饲料被传播到北美洲、大洋洲、欧洲,以及东南亚和中国等地,成为暖温带-热带湿润气候区淡水生态系统的重要外来入侵种。本文结合对喜旱莲子草在原产地的分布状况的考察、原产地和入侵地喜旱莲子草的比较研究,以及入侵生态学研究的最新成果,对该物种在原产地的地理分布和种内变异、生活史特征、入侵机制和控制策略等方面进行评述,以提高我国科研人员对这一外来入侵种的认识,为科学管理和控制提供依据。潘晓云 耿宇鹏 Alejandro SOSA 张文驹 李博 陈家宽 2007植物分类学报2007,45,6:72
2喜旱莲子草茎叶解剖结构从原产地到入侵地的变异式样显示文摘长期以来人们一直认为,外来种入侵及其危害是由于一个物种从原产地到入侵地其环境因子改变(如天敌压力的减弱等)而导致的。近年来,越来越多的研究者开始认识到,生物入侵过程实际上是一个现代人类活动影响下的物种的快速进化过程,生物入侵的进化遗传学已成为入侵生物学研究中最活跃的分支之一。作者比较了来自原产地(阿根廷)和入侵地(中国和美国)的喜旱莲子草(Alternantheraphiloxeroides)的11个种群在茎、叶解剖结构方面的变异式样,发现所研究的19个性状在原产地(阿根廷)和入侵地(中国和美国)的变异情况明显不同:在原产地种群中,共有9个性状指标存在显著差异,遗传率在49–89%之间,这9个性状是气孔密度、气孔指数、茎直径、髓腔直径、维管柱直径、皮层厚度、维管柱面积比、髓腔面积比和叶形指数;而在入侵地种群间,19个性状指标均无明显差异。这表明喜旱莲子草从原产地到入侵地其遗传多样性降低;入侵地喜旱莲子草种群间的形态变异主要为表型可塑性。根据19个形态指标对喜旱莲子草11个种群进行主成分分析和聚类,结果显示:所有入侵地种群和原产地的Ar1种群(SantaFé,59°49′W,29°16′S)聚为一类,原产地的Ar4(Tandil,59°03′W,37°11′S)单独聚为一类,原产地的其他4个种群聚为一类。表明Ar1种群可能与入侵中国的喜旱莲子草在基因型上更为接近。这一结果为进一步揭示喜旱莲子草入侵机理(如杂交适应性)和在原产地寻求对应天敌的生物防治工作提供了基础数据。潘晓云 梁汉钊 Alejandro Sosa 耿宇鹏 李博 陈家宽 2006生物多样性2006,14,3:22

4Surgical perspectives in gastrointestinal disease: A study of quality of life outcomes in esophageal, pancreatic, colon, and rectal cancers显示文摘在外科的结果评价传统地包括了考虑的数据在外科的肿瘤学的仙子起作用的死亡和病态,以及长期的幸存和复发。然而,生命(QOL ) 的质量是另一项重要病人相关的结果措施。QOL 数据能被用来定制治疗并且由在可能不那样被俯看的病人检测物理或心理的问题改进临床的结果,但是它为照顾的有效交货有深刻含意。我们考察仪器与胃肠的恶意在病人为使用明确地开发了的几验证得好的 QOL,包括食道,胰腺并且渲染表面的癌症,并且断定 QOL 评价应该习惯性地在新奇治疗的临床的试用被包括。Kate V Viola Charlotte Ariyan Julie Ann Sosa 2006World Journal of Gastroenterology2006,12,20:5
5Adjuvant therapy sparing in rectal cancer achieving complete response after chemoradiation显示文摘AIM:To evaluate the long-term results of conventional chemoradiotherapy and laparoscopic mesorectal excision in rectal adenocarcinoma patients without adjuvant therapy.METHODS:Patients with biopsy-proven adenocarcinoma of the rectum staged cT3-T4 by endoscopic ultrasound or magnetic resonance imaging received neoadjuvant continuous infusion of 5-fluorouracil for five weeks and concomitant radiotherapy.Laparoscopic surgery was planned after 5-8 wk.Patients diagnosed with ypT0N0 stage cancer were not treated with adjuvant therapy according to the protocol.Patients with ypT1-2N0 or ypT3-4 or N+were offered 5-fluorouracil-based adjuvant treatment on an individual basis.An external cohort was used as a reference for the findings.RESULTS:One hundred and seventy six patients were treated with induction chemoradiotherapy and 170underwent total mesorectal excision.Cancer staging of ypT0N0 was achieved in 26/170(15.3%)patients.After a median follow-up of 58.3 mo,patients withypT0N0 had five-year disease-free and overall survival rates of 96%(95%CI:77-99)and 100%,respectively.We provide evidence about the natural history of patients with localized rectal cancer achieving a complete response after preoperative chemoradiation.The inherent good prognosis of these patients will have implications for clinical trial design and care of patients.CONCLUSION:Withholding adjuvant chemotherapy after complete response following standard neoadjuvant chemoradiotherapy and laparoscopic mesorectal excision might be safe within an experienced multidisciplinary team.Xabier García-Albéniz Rosa Gallego Ralf Dieter Hofheinz Gloria Fernández-Esparrach Juan Ramón Ayuso-Colella Josep Antoni Bombí Carles Conill Miriam Cuatrecasas Salvadora Delgado Angels Ginés Rosa Miquel Mario Pagés Estela Pineda Verónica Pereira Aarón Sosa Oscar Reig Iván Victoria Luis Feliz Antonio María de Lacy Antoni Castells Iris Burkholder Andreas Hochhaus Joan Maurel 2014World Journal of Gastroenterology2014,20,42:5
6Role of colonoscopy in the diagnostic work-up of bowel endometriosis显示文摘AIM:To evaluate the accuracy of colonoscopy for the prediction of intestinal involvement in deep pelvic endometriosis.METHODS:This prospective observational study was performed between September 2011 and July 2014.Only women with both a clinical and imaging diagnosis of deep pelvic endometriosis were included.The study was approved by the local ethics committee and written informed consent was obtained in all cases.Both colonoscopy and laparoscopy were performed by expert surgeons with a high level of expertise with these techniques.Laparoscopy was performed within4 wk of colonoscopic examination.All hypothetical colonoscopy findings(eccentric wall thickening with or without surface nodularities and polypoid lesions with or without surface nodularities of endometriosis)were compared with laparoscopic and histological findings.We calculated the sensitivity,specificity,positive predictive value and negative predictive value for the presence of colonoscopic findings of intestinal endometriosis.RESULTS:A total of 174 consecutive women aged between 21-42 years with a diagnosis of deep pelvic endometriosis who underwent colonoscopy andsurgical intervention were included in our analysis.In 76 of the women(43.6%),intestinal endometrial implants were found at surgery and histopathological examination.Specifically,38 of the 76 lesions(50%)were characterized by the presence of serosal bowel nodules;28 of the 76 lesions(36.8%)reached the muscularis layer;8 of the 76 lesions(10.5%)reached the submucosa;and 2 of the 76 lesions(2.6%)reached the mucosa.Colonoscopic findings suggestive of intestinal endometriosis were detected in 7 of the174(4%)examinations.Colonoscopy failed to diagnose intestinal endometriosis in 70 of the 76 women(92.1%).A colonoscopic diagnosis of endometriosis was obtained in all cases of mucosal involvement,in 3of 8 cases(37.5%)of submucosal involvement,in no cases of muscularis layer involvement and in 1 of 38cases(2.6%)of serosa involvement.The sensitivity,specificity,positive predictive and negative predictive values of colonoscopy for the diagnosis of intestinal endometriosis were 7%,98%,85%and 58%,respectively.CONCLUSION:Being an invasive procedure,colonoscopy should not be routinely performed in the diagnostic work-up of bowel endometriosis.Marco Milone Antonio Mollo Mario Musella Paola Maietta Loredana Maria Sosa Fernandez Olena Shatalova Alessandro Conforti Gianni Barone Giuseppe De Placido Francesco Milone 2015World Journal of Gastroenterology2015,21,16:5
7Varicocele repair in severe oligozoospermia: A case report of post-operative azoospermia显示文摘Varicocele has been implicated as a cause in 35%-50% of patients with primary infertility and up to 81% of men with secondary infertility. Although a large number of reports have shown improvement in the semen parameters after correction of varicocele, other studies have suggested no benefit. We report the first case of azoospermia after surgery in a young infertile male patient with left-sided varicocele and severe oligozoospermia undergoing laparoscopic varicocelectomy. A pregnancy was only achieved with assisted reproductive technology because semen cryopreservation was performed before surgery. In the light of the above, the deterioration of sperm count after varicocele repair in patients with severe oligozoospermia could be due to irreversible impairment of spermatogenesis of such patients, together with the possible temporary damage of the surgical repair. This possible complication could therefore turn the severe oligozoospermia into an indication to perform cryopreservation before surgery, on both clinical and medico-legal grounds. Further research is needed before drawing definitive conclusions regarding the management of varicocele-related severe oligozoospermia.Marco Milone Mario Musella Miguel Emilio Sosa Fernandez Paola Maietta Annarita Sasso Loredana Maria Sosa Fernandez Laura Virginia Sosa Fernandez Francesco Milone 2014World Journal of Clinical Cases2014,2,4:4

12基于企业战略的社会责任财务评价体系研究显示文摘全球竞争环境的变更导致企业社会责任约束力越来越大。企业在承受外部企业社会责任评价体系带来的压力的同时,更希望提高自身的企业社会责任内部管理能力。将企业社会责任与经济绩效联系在一起,从财务评价体系的角度融入社会责任元素,是提高企业社会责任内部管理能力的关键途径。为此,企业可以借助日常财务嵌入、信息披露和财务数据挖掘等三种途径,并将其与企业社会责任战略链接在一起,从财务数据中和战略方向上体现社会责任绩效。帅萍 Johana Sosa Copa 2010生态经济(学术版)2010,,2:2
