Description
技术领域
本发明涉及一种缓解溃疡性结肠炎的长双歧杆菌及其应用,属于微生物技术领域。
背景技术
溃疡性结肠炎(Ulcerative colitis,UC)是一种慢性、特发性炎症紊乱性疾病。病变通常位于结肠黏膜层和黏膜下层,累及直肠和乙状结肠,呈连续性分布。临床上以持续的便血、腹痛、里急后重为典型症状,病程长,较难治愈。随着近些年来发病率的增高,而受到广泛的关注和重视。溃疡性结肠炎的治疗药物是多样化的,但因传统药物治疗的并发症多,且溃疡性结肠炎病情易反复发作,极大的影响了患者的生活质量。
人体肠道是一个错综复杂的微生态系统,其中蕴含着大约100万亿个微生物,肠道菌群正常的生理活动关联着宿主机体的健康运转,在宿主和消化代谢方面发挥着重要的联通作用。例如,将肥胖小鼠的肠道菌群移植到无菌鼠体内会导致肥胖及高血糖。通过对UC患者肠道菌群的临床大数据分析显示,肠道菌群结构的异变与UC的发病密切相关,并且影响伴随着结肠炎的发生和发展全过程。在UC的早期,患者肠道内菌群结构变化的信号就已初见端倪,随着病程的延伸,在UC活动期,患者肠道中双歧杆菌、乳杆菌等原著益生菌的数量出现明显下降。
研究表明,大肠杆菌Nissle和VSL#3等益生菌制剂,可重塑结直肠癌患者的肠道菌群结构,发挥癌细胞清除功能,减少肠黏膜糜烂,稳定肠道微生态。长双歧杆菌是在婴儿和成人的肠道微生物群中发现的最常见的双歧杆菌菌种,目前已被纳入卫生部下发的《可用于食品的菌种名单》及欧洲食品安全局(European Food Safety Agency)安全资格认定清单。长双歧杆菌在宿主肠道内具有良好的定植能力,能在定植后发挥其益生功能,在各种疾病治疗中具有良好的效果。专利CN112458015A公开了一株长双歧杆菌i772及其在调节肠道菌群平衡,缓解酒精对肝脏损伤方面的应用;专利CN112159784A公开了一株长双歧杆菌NX-4及其在制备治疗和/或预防过敏性疾病药物中的应用;专利CN112159784A公开了一株长双歧杆菌 CCFM1029及其在制备治疗和/或预防特应性皮炎食品、药品或保健品中的应用;专利 CN109055269B公开了一株长双歧杆菌CCFM687及其发酵食品在治疗抑郁、自闭、肥胖、及糖尿病等方面的应用;专利CN112111422A公开了一株可缓解结肠炎的假小链双歧杆菌MY40C及其应用。大部分双歧杆菌益生作用的研究仅采用动物模型,在肠道菌群研究方面仅关注其组成及代谢产物的变化,忽略了人体肠道菌群与动物肠道菌群的显著差异对长双歧杆菌拮抗溃疡性结肠炎效果的潜在影响。同时已有研究报道,肠道炎症诱发的全身炎症状态会导致非酒精性脂肪肝、动脉粥样硬化等并发症增加(Bessissow T,et al.Incidenceand predictors of nonalcoholic fatty liver disease by serum biomarkers inpatients with inflammatory bowel disease[J].Inflamm Bowel Dis,2016,22(8):1937-1944;Fumery M,et al.Thromboembolic events and cardiovascular mortalityin inflammatory bowel diseases:a meta-analysis of observational studies[J].JCrohns Colitis,2014,8:469-479.),但目前尚未有任何专利文献报道长双歧杆菌对结肠炎伴随的代谢紊乱的缓解作用。

2、双歧杆菌的分离纯化
(1)粪便样品梯度稀释:在无菌厌氧环境中,取约1g步骤1采集到的粪便样本,加入到9mL生理盐水,得到第一梯度稀释液,吸取1mL第一梯度稀释液于9mL生理盐水,得到第二梯度稀释液,以此类推,共配制9个梯度稀释液;
(2)涂布培养:分别吸取100μL上述所有梯度稀释液分别置于MRS固定培养基上,涂布后至于37℃厌氧条件下培养48h,得到稀释涂布平板;
(3)纯化培养:挑取固体培养基上不同形态的菌落进行划线分离,直至得到边缘整齐,微白,不透明,表面湿润光滑,且形态一致的纯的单菌落(图1);挑取固体培养基上的纯菌落接种于5mL液体MRS培养基中,至于37℃厌氧条件下培养24h,得到纯化培养液。
3、菌种保藏与鉴定

结果显示,长双歧杆菌NSP001能够上调Caco-2细胞产生的SOD(图2),使SOD水平上调2.44%,促进细胞对自由基的清除功能;而长双歧杆菌标准株ATCC15707则使得细胞产生的SOD水平下调了10.15%。
实施例3:长双歧杆菌NSP001对不同肠道菌群环境的溃疡性结肠炎小鼠结肠外观形态和疾病活动指数(DAI)的影响
1、长双歧杆菌NSP001冻存剂的制备:
(1)培养方法:将长双歧杆菌NSP001菌种在固体培养基上划线,长出单菌落后,接种至液体培养基,在37℃下厌氧培养16-24h,达到稳定期。
(2)保护剂的制备:称取半胱氨酸盐酸盐1g/L,甘油200-300g/L,均匀溶解于蒸馏水中,115-121℃灭菌15-20min。

2、制备粪菌溶液:
在无菌厌氧环境中,取健康成年人的粪便,按20%(w/v)加入步骤1中制备的保护剂,混匀后,5000rpm离心10min,取上清,即为灌胃所需的粪菌溶液。
3、实验方法:
取5周龄健康雌性C57BL/6小鼠50只,随机分为五组:正常组(NC)、溃疡性结肠炎组(模型组,M)、鼠源菌群的结肠炎小鼠+长双歧杆菌NSP001组(BD)、人源菌群的结肠炎小鼠+长双歧杆菌NSP001组(AFBD)及结肠炎小鼠+果胶组(阳性对照组,P),每组含小鼠10只。
小鼠饲养于25±2℃、相对湿度50±5%、12h光照12h黑暗的标准化实验室中,适应性喂养一周后开始实验。
实验流程如表2所示,所有小鼠经一周适应期后开始持续为期28天的实验。其中第1-14 天,AFBD组小鼠每24小时灌胃一次抗生素溶液(氨苄青霉素100mg/kg bw,万古霉素50mg/kg bw,新霉素100mg/kg bw,甲硝唑100mg/kg bw),第14天采用qPCR技术检测小鼠肠道菌清除情况;第15-28天,AFBD组小鼠每24小时灌胃一次步骤2制备的粪菌溶液,移植人源肠道菌群,同时,BD及AFBD组小鼠每24小时灌胃一次0.2mL的步骤1制备的长双歧杆菌NSP001冻存剂(5.0×108CFU/mL),P组小鼠灌胃0.2mL的果胶溶液(CP Kelco, 300mg/kg bw)。第1-21天,所有小鼠均自由饮用灭菌蒸馏水,第22-28天,除NC组小鼠自由饮用灭菌蒸馏水,其余组小鼠均改为自由饮用含3%DSS的灭菌蒸馏水。
每日监测记录各组小鼠的状态,并按表3计算疾病活动指数(DAI)。28天实验结束后,处死所有小鼠,收集结肠组织。
表2实验流程
表3疾病活动指数评分
注:正常粪便:成形粪便;松散粪便:不黏附于肛门的糊状、半成形粪便;稀便:黏附于肛门的稀水样粪便。
实验结果如图3所示,连续7天引用含有3%DSS的蒸馏水后,BD组小鼠的DAI指数为2.03(p<0.05),AFBD组小鼠DAI指数为2.07(p<0.05),较模型组小鼠DNA指数分别降低了25.6%和23.8%,因此长双歧杆菌NSP001干预能显著降低因溃疡性结肠炎导致的DAI 指数上升。模型组小鼠的结肠明显萎缩长度仅有对照组的58%,而BD及AFBD组小鼠结肠长度得到了显著的恢复,长度恢复到对照组结肠长度的83%(图3B)。以上结果表明,本发明长双歧杆菌NSP001在鼠源及人源肠道菌群环境下均能够降低溃疡性结肠炎小鼠的疾病活动指数(DAI),并恢复结肠长度。
实施例4:长双歧杆菌NSP001对不同肠道菌群环境的溃疡性结肠炎小鼠结肠通透性及结肠组织结构的影响
实验方法同实施例2,在处死前6h开始禁食,处死前4h灌胃600mg/kg小鼠体重的Dextran-FITC,之后处死所有小鼠,收集血清及结肠,通过检测血清中Dextran-FITC的荧光强度来说明各组小鼠结肠通透性的变化,采用HE染色法观察各组小鼠结肠的形态学变化。
实验结果如图4所示,连续7天的含3%DSS的饮用水将小鼠血清中FITC含量从81.30 ng/mL升高至650.21ng/mL(p<0.001),而经长双歧杆菌NSP001干预后,BD组小鼠血清中 FITC含量降低至158.43ng/mL(p<0.001),AFBD组小鼠血清中FITC含量降低至116.37ng/mL (p<0.001),使得小鼠结肠通透性接近正常小鼠水平(图4A)。经DSS造模后,模型组小鼠结肠可见明显炎症细胞浸润,出现大量炎症细胞,结肠绒毛破坏,肠隐窝消失,长双歧杆菌NSP001干预后,BD组及AFBD组小鼠结肠炎症细胞浸润均较模型组减少,且可见整齐绒毛和清晰的隐窝结构(图4B)。以上结果表明,本发明长双歧杆菌NSP001在鼠源及人源肠道菌群环境下均能够降低溃疡性结肠炎症小鼠结肠通透性,并维持肠道组织结构完整。
实施例5:长双歧杆菌NSP001对不同肠道菌群环境的溃疡性结肠炎小鼠免疫因子及氧化应激水平的调节作用
实验方法同实施例2,在实验结束后处死所有小鼠,收集结肠组织,采用ELISA试剂盒 (南京森贝伽生物科技有限公司产品)测定其中炎症因子及髓过氧化物酶(MPO)的浓度。
实验结果如图5所示,连续7天的含3%DSS的饮用水显著升高了小鼠结肠中TNF-α和 IL-6的含量,分别从124.53ng/L及14.99pg/mL提高至150.32ng/L(p<0.05)及28.96pg/mL (p<0.001),经长双歧杆菌NSP001干预后,BD组小鼠结肠中TNF-α和IL-6分别降低至118.78 ng/L(p<0.01)和20.67pg/mL(p<0.01),AFBD组小鼠结肠中TNF-α和IL-6分别降低至107.79 ng/L(p<0.001)和19.34pg/mL(p<0.001),接近正常组小鼠水平。同时,正常组小鼠MPO 水平为12.52ng/L,模型组小鼠则升高至18.58ng/L(p<0.001),经长双歧杆菌NSP001干预后,BD组小鼠结肠MPO水平降低至15.34ng/L(p<0.01),AFBD组小鼠降低至16.00ng/L (p<0.05),MPO水平显著降低。以上结果表明,本发明长双歧杆菌NSP001在鼠源及人源肠道菌群环境下均能够降低溃疡性结肠炎小鼠的促炎因子,并缓解组织的过度氧化损伤。
实施例6:长双歧杆菌NSP001对不同肠道菌群环境的溃疡性结肠炎小鼠结肠内容物中短链脂肪酸的调节作用
实验方法同实施例2,在实验结束后处死所有小鼠,收集结肠内容物,采用GC-MS技术分别检测其中短链脂肪酸的组成变化。
实验结果如图6所示,相比正常组小鼠,模型组小鼠结肠内容物中的乙酸、丙酸和戊酸从52.44mmol/g、22.05mmol/g、2.19mmol/g降低至30.57mmol/g(p<0.001)、13.11mmol/g (p<0.001)及1.47mmol/g(p<0.05)。经长双歧杆菌NSP001干预后,BD组小鼠的乙酸和丙酸分别增加至40.03mmol/g(p<0.05)及19.58mmol/g(p<0.01),AFBD组小鼠的乙酸和丙酸分别增加至40.20mmol/g(p<0.05)及19.80mmol/g(p<0.001)。以上结果表明,本发明长双歧杆菌NSP001在鼠源及人源肠道菌群环境下均能够增加溃疡性结肠炎小鼠肠道中短链脂肪酸的含量,说明溃疡性结肠炎小鼠的肠道菌群逐渐恢复正常,短链脂肪酸在维持肠道健康、在预防和改善多种非传染性疾病方面中发挥了重要作用,推测长双歧杆菌NSP001还可以有效预防结肠炎并发症的发生。
实施例7:长双歧杆菌NSP001对不同肠道菌群环境的溃疡性结肠炎小鼠代谢紊乱的调节作用
实验方法同实施例2,在实验结束后处死所有小鼠,收集血清,采用UPLC-triple-TOF/MS 技术分别检测其代谢物组成。
实验结果如图7所示,相比正常组小鼠,模型组小鼠血清中代谢物组成发生了明显的变化,其中与结肠炎相关结肠癌发生发展密切关联的磷酸酯代谢通路中的磷脂酰丝氨酸(PE) 显著上调,信号强度从4.379上升至5.393。不仅如此,与机体能量代谢相关的TCA循环中关键代谢物柠檬酸的信号强度从3.317下降至3.239,神经传导相关的关键代谢物7-二甲基黄嘌呤的信号强度从2.201下降至1.869。说明,小鼠患有溃疡性结肠炎的同时,很可能伴随有机体代谢失调的症状。
相比模型组小鼠,如图8所示,长双歧杆菌NSP001干预后血清代谢物组成明显不同。其中AFBD组小鼠血清中柠檬酸的信号强度从3.239上升至3.338,通过SMPDB数据库比对分析,推测小鼠的TCA循环通路信号得到了明显的上调(p<0.05)(图8A)。BD组小鼠血清中7-二甲基黄嘌呤的信号强度从1.869上升至2.350,通过SMPDB数据库比对分析,推测小鼠的咖啡因代谢通路信号得到了明显的上调(p<0.001)(图8B)。以上结果表明,本发明长双歧杆菌NSP001在鼠源及人源肠道菌群环境下从不同信号通路预防或恢复肠炎伴随的代谢紊乱,在溃疡性结肠炎治疗过程中常常会使用到糖皮质激素等激素药,可能会进一步加重代谢紊乱,本发明长双歧杆菌NSP001可与现有的治疗药物协同以预防或减少代谢紊乱的发生。
