粪便中肿瘤M2型丙酮酸激酶联合潜血试验检测结直肠癌的效率分析 [PDF]
【目的】探讨粪便中肿瘤M2型丙酮酸激酶(tumor M2-PK)联合潜血试验检测结直肠癌的临床意义。【方法】43例结直肠癌病人和43例健康正常人的粪便标本各1份,应用酶联免疫吸附测定法(ELISA)检测标本的tumor M2-PK水平,同时行免疫法粪便潜血试验(IFOBT)检测,比较二者单独及联合筛查结直肠癌的效率。【结果】粪便中tumor M2-PK水平中位值(最大值,最小值):结直肠癌组为8.6(0,59.0)U/mL,健康对照组为0.6(0,9.0)U/mL,两组差异有显著性意义(U=319,P ...

野生哺乳动物肠道微生态由肠道正常菌群及其所生活的环境共同构成,与动物个体生理和健康密切相关。粪便样品对野生动物肠道微生态的研究具有特殊价值,基于粪便组学将可能从多个角度对野生哺乳动物肠道微生态在外界环境、饮食和疾病等方面提供重要信息。本文主要综述了基于粪便的高通量组学技术及其在野生哺乳动物研究中的应用,重点关注野生与圈养、气候与地域变化,以及疾病状态的肠道微生物组学和代谢组学的研究应用,以期推动生物技术在我国野生哺乳动物研究中的发展,为野生动物保护提供新的研究手段和研究方向。

目前黑龙江东北虎林园有东北虎1 000多只,每天会排出大量的粪便,之前仅将虎粪作为垃圾处理,耗费大量的人力、物力和财力,而且还存在处理不及时造成对水源、空气、土壤等污染的问题。本研究通过系统比较野生东北虎和人工圈养东北虎粪便的矿物质含量,分析不同饲喂条件下人工圈养东北虎虎粪的矿物质含量和营养组成,在充分认识虎粪的环境污染问题的基础上,探讨虎粪的有效利用问题,提出了虎粪可作为沼气池发酵原料和有机肥料等潜在的利用途径,为改善和美化东北虎林园的环境,同时为开发虎粪资源,变废为宝提供了新的思路。

粪便隐血试验是检测消化道微量出血的重要手段。本文用三种隐血试验:血红蛋白定量试验(HQT)、反向间接血球凝集试验(RPHA)和联苯胺试验(BT)对不同消化道疾病患者的粪便进行检测。结果表明隐血的检出用HQT和RPHA较BT更为特异和敏感。

为了解卷羽鹈鹕(Pelecanus crispus)源大肠埃希菌(Escherichia coli)和粪肠球菌(Enterococcus faecalis)耐药性特征,采集圈养卷羽鹈鹕粪便9份,用全自动微生物生化鉴定法进行鉴定。结果表明:分别从9份粪便样中分离鉴定出大肠埃希菌9株,粪肠球菌7株。药敏试验结果显示,大肠埃希菌对氨苄西林、四环素和磺胺异恶唑的耐药性均较强,对阿莫西林/克拉维酸、头孢噻呋、多西环素等均较为敏感;粪肠球菌对青霉素、红霉素、四环素的耐药性均较强,对链霉素、呋喃妥因和氯霉素等较敏感 ...

Abstract The effectiveness and safety of electroacupuncture (EA) for constipation have been confirmed by numerous clinical studies and experiments, and there are also studies on the efficacy of EA for Parkinson's disease (PD) motor symptoms. However, there are few researches on EA for PD constipation.

Invertebrate‐derived DNA (iDNA) has enabled the identification and quantification of ecological interactions within trophic networks and its use in biodiversity assessment. The dung beetle iDNA currently uses live beetles. However, the effectiveness of the iDNA approach hinges on the successful detection of mammalian DNA from specimens collected via ...

Highlights For the first time, our study contributed a systematic evaluation of bile acid (BA) profiles in plasma, feces and liver tissue and gut microbiota changes triggered by fasting‐refeeding cycle in mice. Our work clearly demonstrated that overnight fasting leads to significant, but reversible changes in BA profiles and gut microbiota composition.
