Description
技术领域
1 本发明属于医疗保健食品领域,具体涉及一种促进胃部微生物菌群平衡的组合物,涉及低聚甘露糖,大分子量壳寡糖和壳聚糖的配伍组合物及其制备方法和应用。
背景技术
2 胃癌是全球癌症相关死亡的第三大原因,当前大量研究认为幽门螺杆菌(Hp)的感染是导致胃癌的最主要危险因素,它可以促进癌前病变(如胃萎缩、肠化、不典型增生)的发展,最终导致胃癌的发生。Hp感染非常常见,全球感染率大约50%左右,其中1-3%的感染者会发展为胃癌。
3 目前主要的研究认为,Hp是慢性胃炎、消化性溃疡和胃癌的重要致病因子,因此大量的研究都在解决如何根除Hp。目前临床采用多联抗生素高强度联合治疗Hp,但是会存在很多问题,抗生素药物的副作用大以及病人依从性差,Hp耐药菌株的产生,药物价格昂贵等。专利CN02136931,一种用于抑杀Hp的生物制剂,主要组分为溶葡萄球菌酶,溶菌酶,乳链菌肽,认为对不同分型的Hp均有明显的抑杀作用。谢勇等人的研究发现壳聚糖及衍生物在体内外具有抗Hp的作用。
4 导致胃癌发生的主要因素有Hp菌株特异性毒力因子,遗传因素,饮食因素、环境因素,此外还有胃内菌群。之前的研究热点主要集中于单一菌群,即幽门螺杆菌与胃癌的关系,随着对核糖体RNA基因组测序、系统发生分析、计算方法的进步,发现了正常人胃组织中还有其他微生物群的存在,主要的菌群种类,有以下五种菌门:变形菌门(69.3%)、厚壁菌门(14.7%)、拟杆菌门(9%)、放线菌门(4.3%、梭杆菌门(1.3%)。菌群作为一个共生体,可以阻止病原体入侵和防止肿瘤发生,当共生的微妙平衡被中断,表现为微生态失调而导致机体的疾病过程,其中也包括癌症。
5 研究发现,引起胃部微生态失调的原因主要有:(1)在抗生素治疗过程中对致病菌抑制的同时,也破坏了正常菌群的存活;(2)宿主的不同生理状态引起的菌群防御屏障被破坏,可能引起正常菌群比例失调或转移至其他非正常部位等;(3)胃动力的异常导致菌群失调的形成;(4)饮食结构单一或无纤维食物可能影响菌群的生态平衡,导致菌群发生变化;(5)胃肠道免疫屏障受损可能引起需氧菌及厌氧菌大量繁殖,破坏菌群平衡。
6 在正常的胃组织中的菌群,一般以少量非Hp菌为主,多数为韦荣氏球菌属、乳杆菌属和梭菌属。与消化不良患者胃内菌群比较,胃癌患者胃内细菌数量有所增加,优势菌群为链球菌、乳酸菌、韦荣氏球菌等,这可能与胃酸减少、pH升高,产生有利于细菌生长的微环境有关,进而破坏胃部微生态平衡,并产生过量代谢产物损伤胃部粘膜及诱发癌变。
7 胃肠道菌群能够通过促进细胞凋亡、抑制细胞增殖以及炎症发生等方面发挥促进健康、预防疾病的作用。胃肠道微生态失调可能导致病原微生物的入侵,进而诱发胃癌。重建胃肠道微生态菌群,维持胃部的微生态平衡有利于维持人体的胃肠道健康和人体的整体健康。
