3肝脏移植治疗不可切除结直肠癌肝转移的前瞻性试验性研究显示文摘背景和目的无法手术切除的结直肠癌肝转移(Colorectal Liver Metastases,CLMs)患者预后差,存活时间极少超过5年。尽管对部分肝脏原发及继发恶性肿瘤患者施行肝脏移植可获得较佳的预后,但目前仍普遍认为,结直肠癌肝转移是肝移植的绝对禁忌证。1995年之前,曾针对结直肠癌肝转移患者进行过数例肝脏移植,但预后不良(5年生存率仅为18%),自此放弃对此类患者进行肝脏移植。然而,目前总体肝移植生存率较当时提高30%左右。基于此,结直肠癌肝转移患者肝移植后的5年生存率有望达到50%。因此,本试验性研究旨在探讨CLM患者在接受肝移植后的潜在长期生存获益。方法自2006年11月到2011年3月,在此项前瞻性、试验性研究中,共对21名无法切除的结直肠癌肝转移患者进行肝移植术。患者入选标准包括一般状况良好(ECOG 1分或以下)、结直肠癌伴无法切除的单纯肝转移、原发肿瘤已行根治性切除以及移植前接受过至少6周的化疗。结果入组的患者肝脏肿瘤负荷及原发肠癌T/N分期相异;肝移植术前,76%(16/21)患者存在至少一线化疗进展。Kaplan-Meier推算患者1、3及5年总体生存率分别为95%、68%及60%。与预期相同,移植术后复发转移现象普遍,21例中19例在中位时间6(2~24)个月内发生局部复发或转移。其中,单个肺转移灶7例;其余多部位(包括肺)转移者9例,包括移植肝新发转移7例,骨转移5例,卵巢或肾上腺转移3例,腹膜转移1例,腹主动脉旁淋巴结转移2例。2例发生直肠癌局部复发。然而,绝大多数的转移癌可经手术切除或射频治疗,且经过干预后,中位随访时间27个月(8~60个月),33%(7例)患者无病生存。肝移植术前肝脏肿瘤负荷、初次手术距肝移植的时间(肠癌切除距肝移植超过2年者生存获益更显著)以及化疗后肿瘤进展均为影响预后的显著性因素。结论研究结果表明,对于此类患者人群,肝移植术后总体生存率显著高于化疗,而化疗为该患者人群现有的唯一治疗方式。此外,本研究显示的总体生存率与可切除的结直肠癌肝转移患者以及接受再次肝移植的非恶性肿瘤患者情况相当。同时,对预后因素进行手术策略筛选,应可进一步改善患者预后。(临床研究注册编号ClinicalT rials.gov:NCT01311453)。Hagness M Foss A Line PD 张信华 2013消化肿瘤杂志(电子版)2013,5,4:8
4Plecanatide and dolcanatide, novel guanylate cyclase-C agonists, ameliorate gastrointestinal inflammation in experimental models of murine colitis显示文摘AIM: To evaluate the effect of orally administeredplecanatide or dolcanatide, analogs of uroguanylin, on amelioration of colitis in murine models.METHODS: The cyclic guanosine monophosphate(cG MP) stimulatory potency of plecanatide and dolcanatide was measured using a human colon carcinoma T84 cellbased assay. For animal studies all test agents were formulated in phosphate buffered saline. Sulfasalazine or 5-amino salicylic acid(5-ASA) served as positive controls. Effect of oral treatment with test agents on amelioration of acute colitis induced either by dextran sulfate sodium(DSS) in drinking water or by rectal instillation of trinitrobenzene sulfonic(TNBS) acid, was examined in BALB/c and/or BDF1 mice. Additionally, the effect of orally administered plecanatide on the spontaneous colitis in T-cell receptor alpha knockout(TCRα-/-) mice was also examined. Amelioration of colitis was assessed by monitoring severity of colitis, disease activity index and by histopathology. Frozen colon tissues were used to measure myeloperoxidase activity.RESULTS: Plecanatide and dolcanatide are structurally related analogs of uroguanylin, which is an endogenous ligand of guanylate cyclase-C(GC-C). As expected from the agonists of GC-C, both plecanatide and dolcanatide exhibited potent cG MP-stimulatory activity in T84 cells. Once-daily treatment by oral gavage with either of these analogs(0.05-0.5 mg/kg) ameliorated colitis in both DSS and TNBS-induced models of acute colitis, as assessed by body weight, reduction in colitis severity(P < 0.05) and disease activity index(P < 0.05). Amelioration of colitis by either of the drug candidates was comparable to that achieved by orally administered sulfasalazine or 5-ASA. Plecanatide also effectively ameliorated colitis in TCRα-/- mice, a model of spontaneous colitis. As dolcanatide exhibited higher resistance to proteolysis in simulated gastric and intestinal juices, it was selected for further studies. CONCLUSION: This is the first-ever study reporting the therapeutic utility of GC-C agonists as a new class of orally delivered and mucosally active drug candidates for the treatment of inflammatory bowel diseases.Kunwar Shailubhai Vaseem Palejwala Krishna Priya Arjunan Sayali Saykhedkar Bradley Nefsky John A Foss Stephen Comiskey Gary S Jacob Scott E Plevy 2015World Journal of Gastrointestinal Pharmacology and Therapeutics2015,6,4:5
5中国的寄生性杜鹃及其宿主多样性(英文)显示文摘通过多年的调查资料、观鸟爱好者所提供的图片和文献整理,我们对多杜鹃寄生系统下的中国寄生性杜鹃及其宿主的多样性进行了系统研究。在中国分布的17种寄生性杜鹃中,迄今已发现11种杜鹃的宿主达55种,均为雀形目鸟类,隶属于15科,其中莺科、鸫科和画眉科分别占到寄生记录总数的 22.6%、20.8% 和 17.0%。大杜鹃(Cuculus canorus)的宿主种类最多(45.5%),是中国最常见、宿主多样性最丰富的寄生性杜鹃。不同种类的寄生性杜鹃的卵色不同,而且杜鹃与其宿主之间均呈现明显的卵色多态性,为典型的卵色协同进化。基于人眼观察,大杜鹃、小杜鹃(C. poliocephalus)和八声杜鹃(Cacomantis merulinus)的卵色均与其宿主高度模拟,而鹰鹃(Cuculus sparverioides)、中杜鹃(C. saturatus)和翠金鹃(Chrysococcyx maculatus)则产非模拟的卵。目前仍有6种寄生性杜鹃的宿主不详,亟待加强研究。杨灿朝 梁伟 Anton ANTONOV 蔡燕 Brd G.STOKKE Frode FOSSφY Arne MOKSNES Eivin RφSKAFT 2012Chinese Birds2012,,1:5
6Oral treatment with plecanatide or dolcanatide attenuates visceral hypersensitivity via activation of guanylate cyclase-C in rat models显示文摘AIM To investigate the effects of plecanatide and dolcanatide on maintenance of paracellular permeability, integrity of tight junctions and on suppression of visceral hypersensitivity. METHODS Transport of fluorescein isothiocyanate(FITC)-dextran was measured to assess permeability across cell monolayers and rat colon tissues. Effects of plecanatide and dolcanatide on the integrity of tight junctions in Caco-2 and T84 monolayers and on the expression and localization of occludin and zonula occludens-1(ZO-1) were examined by immunofluorescence microscopy. Anti-nociceptive activity of these agonists was evaluated in trinitrobenzene sulfonic acid(TNBS)-induced inflammatory as well as in non-inflammatory partial restraint stress(PRS) rat models. Statistical significance between the treatment groups in the permeability studies were evaluated using unpaired t-tests.RESULTS Treatment of T84 and Caco-2 monolayers with lipopolysaccharide(LPS) rapidly increased permeability, which was effectively suppressed when monolayers were also treated with plecanatide or dolcanatide. Similarly, when T84 and Caco-2 monolayers were treated with LPS, cell surface localization of tight junction proteins occludin and ZO-1 was severely disrupted. When cell monolayers were treated with LPS in the presence of plecanatide or dolcanatide, occludin and ZO-1 were localized at the cell surface of adjoining cells, similar to that observed for vehicle treated cells. Treatment of cell monolayers with plecanatide or dolcanatide without LPS did not alter permeability, integrity of tight junctions and cell surface localization of either of the tight junction proteins. In rat visceral hypersensitivity models, both agonists suppressed the TNBS-induced increase in abdominal contractions in response to colorectal distension without affecting the colonic wall elasticity, and both agonists also reduced colonic hypersensitivity in the PRS model. CONCLUSION Our results suggest that activation of GC-C signaling might be involved in maintenance of barrier function, possibly through regulating normal localization of tight junction proteins. Consistent with these findings, plecanatide and dolcanatide showed potent antinociceptive activity in rat visceral hypersensitivity models. These results imply that activation of GC-C signaling may be an attractive therapeutic approach to treat functional constipation disorders and inflammatory gastrointestinal conditions.Illona-Marie Boulete Anusha Thadi Catherine Beaufrand Viren Patwa Apoorva Joshi John A Foss E Priya Eddy Helene Eutamene Vaseem A Palejwala Vassilia Theodorou Kunwar Shailubhai 2018World Journal of Gastroenterology2018,24,17:5

8Origin of pit chains in the floor of lunar Copernican craters显示文摘There are small pit chains in the floor of lunar Copernican craters. They are usually so small in scale that there are few lunar spacecrafts to detect their detailed morphology. Combining camera data from Lunar Orbiter, Lunar Reconnaissance Orbiter (LRO), Kaguya and Chang’e-1 missions, 5 representative large Copernican craters on various terrains of the lunar surface are chosen to study the origin of the pit chains in the crater floor. The morphology and distribution characteristic of the pit chains are referred by the high resolution images in this research. It is suggested that it is the magma activities from the subsurface magma layer combining with the existence of fractures and faults under the crater floor that leaded the formation of the pit chains. The model is further verified and discussed using the regolith thickness data in the crater floor. Our model suggests that the pit chains are still developing in the floor of the Copernican craters and the Moon may not be totally cold. Finally, the model limitation and potential future work are discussed based on available data.XIAO ZhiYong 1* , ZENG ZuoXun 1,2 , XIAO Long 1,2 , FA WenZhe 3 & HUANG Qian 3,4 1 Faculty of Earth Sciences, China University of Geosciences, Wuhan 430074, China 2 Research Center for Space Science and Technology, China University of Geosciences, Wuhan 430074, China 3 Institut de Physique du Globe de Paris, 4 Avenue de Neptune, Saint Maur des Fosse’s, 94100, France 4 Shanghai Astronomical Observatory, Chinese Academy of Sciences, Shanghai 200030, China 2010Science China(Physics,Mechanics & Astronomy)2010,53,12:4
