【摘要】 目的:探討腸道菌群失調(diào)對(duì)代謝綜合征(MS)兒童免疫功能及血清炎癥因子的影響。方法:選取2017年8月-2019年6月本院轄區(qū)內(nèi)查體篩選出的128例MS患兒。經(jīng)糞便涂片檢查,腸道菌群失調(diào)的有76例,在出現(xiàn)腸道菌群失調(diào)的患兒中隨機(jī)選擇52例作為A組,其他未出現(xiàn)腸道菌群失調(diào)的52例代謝綜合征患兒作為B組,隨機(jī)選擇查體正常的健康兒童52例作為C組。比較三組體格與血生化檢查結(jié)果和免疫功能及血清炎癥因子檢測結(jié)果。結(jié)果:三組BMI、腰臀比、SBP、DBP、TG、FBG、HDL-C比較,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05)。三組IgA、IgM、IgG水平比較,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05)。C組IgA、IgM、IgG水平均低于A組和B組,B組IgM、IgG水平均低于A組,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05)。三組TNF-α、IL-6、hs-CRP水平比較,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05);C組TNF-α、IL-6、hs-CRP水平均低于A組和B組,B組TNF-α、hs-CRP水平均低于A組,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05)。結(jié)論:腸道菌群的改變與MS相關(guān),一旦失調(diào),會(huì)打破機(jī)體的免疫平衡,導(dǎo)致MS兒童免疫功能下降,血清炎癥因子上升。

[Abstract] Objective: To investigate the effects of intestinal flora imbalance on immune function and serum inflammatory factors in children with metabolic syndrome (MS). Method: A total of 128 children with MS were selected from August 2017 to June 2019 within the jurisdiction of our hospital. According to stool smear, 76 cases had intestinal flora imbalance, among the children with intestinal flora imbalance, 52 cases were randomly selected as group A, 52 cases of MS without intestinal flora imbalance were selected as group B, and 52 cases of healthy children with normal physical examination were randomly selected as group C. The results of physical and blood biochemical examination, immune function and serum inflammation were compared among three groups. Result: The differences in BMI, waist-hip ratio, SBP, DBP, TG, FBG and HDL-C among three groups were statistically significant (P<0.05). Comparison of IgA, IgM and IgG levels among three groups, the differences were statistically significant (P<0.05). The IgA, IgM and IgG levels of group C were all lower than those of group A and B, and the IgM and IgG levels of group B were all lower than those of group A, there were statistically significant differences (P<0.05). The levels of TNF-α, IL-6 and hs-CRP in the three groups were significantly different (P<0.05). The levels of TNF-α, IL-6 and hs-CRP in group C were all lower than those in group A and B, and the levels of TNF-α and hs-CRP in group B were lower than those in group A, there were statistically significant differences (P<0.05). Conclusion: The change of intestinal flora is related to MS. Once the imbalance occurs, the immune balance of the body will be disturbed, leading to the decrease of immune function and the increase of serum inflammatory factors in children with MS.

研究顯示,腸道菌群失調(diào)導(dǎo)致腸道細(xì)菌死亡后,脂多糖(LPS)作為細(xì)胞內(nèi)毒素從溶解的菌體釋放入腸道環(huán)境并進(jìn)入血液循環(huán),與其受體蛋白LPS結(jié)合蛋白相結(jié)合后引發(fā)宿主炎癥級(jí)聯(lián)反應(yīng),導(dǎo)致機(jī)體固有免疫被激活,通過一系列信號(hào)轉(zhuǎn)導(dǎo)過程導(dǎo)致IL-6、TNF-α等炎癥因子的大量表達(dá)[19-20]。因此,腸道菌群失調(diào)患者經(jīng)常處于一種長期、慢性輕度炎癥狀態(tài)。本研究發(fā)現(xiàn),C組TNF-α、IL-6、hs-CRP水平均低于A組和B組,B組TNF-α、hs-CRP水平均低于A組,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05)。表明腸道菌群具有抗炎的作用,當(dāng)腸道菌群失調(diào)時(shí),人體會(huì)發(fā)生炎癥反應(yīng),并影響著MS的發(fā)生,與上述研究結(jié)果一致。
綜上所述,腸道菌群的改變與MS相關(guān),一旦失調(diào),會(huì)打破機(jī)體的免疫平衡,導(dǎo)致MS兒童免疫功能下降,血清炎癥因子上升。通過平衡腸道菌群的結(jié)構(gòu),可以改善免疫功能,減少機(jī)體的炎癥反應(yīng)的發(fā)生,這為治療MS兒童提供了新的依據(jù)。
