[Abstract] Objective To observe bifidobacteria triple capsule on the levels of CD4+, CD24+ regulatory T cells and IL-10 for patients with ulcerative colitis. Methods Selected 134 cases of patients with ulcerative colitis clinical research data beds, in accordance with the principles of the randomized patients were divided into observation group and control group, with 67 cases in each. Control patients received conventional basic therapy, observation group received probiotics in capsule treatment on the basis of the control group. The efficacy of the two groups of patients and levels of serum CD4+, CD24+ T cells and IL-10 were compared. Results The patients in clinical symptom scores decreased significantly higher percentage, two groups of patients after treatment colitis disease scores were significantly lower than before treatment, and display observed between the two groups of patients after treatment colitis disease scores were significantly lower than the control group. Two groups of patients after treatment serum CD4 +, CD24 + regulatory T cells was significantly higher in CD4+T cells and the percentage of IL-10 levels than before treatment. Conclusion Probiotics capsules adjuvant treatment of ulcerative colitis patients can be adjusted by CD4 +, CD24 + regulatory T cells and IL-10 levels.

3 討論
潰瘍性結(jié)腸炎患者的發(fā)病機(jī)制尚未完全明確,但腸道菌群功能以及免疫功能失調(diào)均與潰瘍性結(jié)腸炎的發(fā)生和發(fā)展存在密切的聯(lián)系[4],微生態(tài)制劑在調(diào)節(jié)腸道正常菌群功能方面的作用已經(jīng)被驗(yàn)證[6],雙歧三聯(lián)活菌膠囊主要包括長(zhǎng)型雙歧桿菌、保加利亞乳桿菌以及嗜熱鏈球菌3種細(xì)菌,此三種細(xì)菌均是腸道重要的益生菌,在維持腸道微生態(tài)平衡、防御致病菌和病毒入侵、促進(jìn)腸道正常菌群生長(zhǎng)繁殖方面作用顯著[7]。既往潰瘍性結(jié)腸炎以抗生素抗感染,5-氨基水楊酸制劑等對(duì)癥治療為主[8],但療效差強(qiáng)人意,已有研究[9]證實(shí)應(yīng)用微生態(tài)制劑聯(lián)合治療潰瘍性結(jié)腸炎療效顯著,但對(duì)于其起效機(jī)制的研究尚不多見。
患者機(jī)體免疫功能失調(diào)是潰瘍性結(jié)腸炎發(fā)病的重要因素,且與其病情發(fā)展密切相關(guān)[10],而微生態(tài)制劑在調(diào)節(jié)腸道正常菌群功能的同時(shí),對(duì)于患者的免疫功能是否也能起到有效的調(diào)節(jié)作用值得研究。調(diào)節(jié)性T細(xì)胞在調(diào)節(jié)功能性T細(xì)胞亞群功能方面具有重要作用,在多種免疫系統(tǒng)相關(guān)疾病的發(fā)生發(fā)展中均具有重要意義。有研究提出CD4+、CD24+調(diào)節(jié)T細(xì)胞具有免疫無(wú)能性與抑制性兩大功能特征,主要通過抑制自身反應(yīng)性T細(xì)胞的免疫反應(yīng),從而減少TGF-β、IL-10等細(xì)胞因子的分泌,在自身免疫性疾病中具有重要意義[11]。CD4+、CD24+調(diào)節(jié)T細(xì)胞的產(chǎn)生可能與腸道菌群存在一定的關(guān)系,有研究[12]認(rèn)為腸道長(zhǎng)期暴露在正常菌群的外源性抗原中,可以在一定程度上誘導(dǎo)CD4+、CD24+調(diào)節(jié)T細(xì)胞的產(chǎn)生,也有研究[13]認(rèn)為腸道菌群可以抑制非成熟樹突狀細(xì)胞的成熟,側(cè)面促進(jìn)CD4+、CD24+調(diào)節(jié)T細(xì)胞的發(fā)育和增殖,以維持正常菌群的免疫功能,因此推測(cè)微生態(tài)制劑調(diào)節(jié)腸道正常菌群功能可能通過以上機(jī)制改善患者的免疫功能從而達(dá)到輔助治療潰瘍性結(jié)腸炎患者的作用。IL-10是重要的炎癥因子,主要由Th2細(xì)胞、單核巨噬細(xì)胞以及活化的B細(xì)胞產(chǎn)生,其可以通過抑制單核細(xì)胞的活性,抑制腸道炎癥反應(yīng)[14]。雙歧三聯(lián)活菌膠囊所含益生菌在腸道增殖后的代謝產(chǎn)物也是調(diào)節(jié)腸道內(nèi)環(huán)境的重要物質(zhì),可以在一定程度上調(diào)節(jié)腸道黏膜的免疫功能,促進(jìn)IL-10的表達(dá)水平,這也是雙歧三聯(lián)活菌膠囊輔助治療潰瘍性結(jié)腸炎的可能機(jī)制。
本研究結(jié)果顯示采用雙歧三聯(lián)活菌膠囊輔助治療的潰瘍性結(jié)腸炎患者,治療6個(gè)月后臨床癥狀評(píng)分下降百分比以及顯著高于對(duì)照組,結(jié)腸炎癥評(píng)分顯著低于對(duì)照組。外周血CD4+、CD24+調(diào)節(jié)T細(xì)胞占CD4+T細(xì)胞的百分比及IL-10水平均顯著高于對(duì)照組。由此總結(jié),CD4+、CD24+調(diào)節(jié)T細(xì)胞和IL-10在潰瘍性結(jié)腸炎患者的發(fā)病和發(fā)展中存在重要作用和意義,雙歧三聯(lián)活菌膠囊輔助治療的潰瘍性結(jié)腸炎患者可以調(diào)節(jié)腸道菌群功能,提高CD4+、CD24+調(diào)節(jié)T細(xì)胞和IL-10水平的表達(dá),提高療效。
