【摘要】目的探討消化性潰瘍患者外周血細(xì)胞免疫及體液免疫功能的變化及臨床意義。方法選擇2014年1月—2015年1月杭州師范大學(xué)附屬醫(yī)院門診及住院的連續(xù)經(jīng)胃鏡確診的消化性潰瘍患者122例為潰瘍組，另選擇同期體檢中心體檢健康者70例為對照組，潰瘍組患者根據(jù)是否感染幽門螺桿菌分為幽門螺桿菌陽性亞組(Hp+亞組)85例和幽門螺桿菌陰性亞組(Hp-亞組)37例，根據(jù)是否出血分為出血亞組58例和未出血亞組64例。檢測外周血細(xì)胞免疫指標(biāo)(包括CD3、CD4、CD8、CD4/CD8、CD19、CD56)及體液免疫指標(biāo)(IgG、IgA、IgM、IgE、C3、C4)水平，出血亞組中30例大便隱血試驗陽性患者大便隱血試驗轉(zhuǎn)陰后復(fù)查外周血細(xì)胞免疫指標(biāo)及體液免疫指標(biāo)。結(jié)果潰瘍組患者外周血CD3、CD4、CD4/CD8、CD19、CD56、C3、C4水平較對照組降低，IgG水平較對照組升高(P<0.05)；Hp+亞組患者外周血CD3、CD4、CD8、CD19、IgM、IgE水平較Hp-亞組升高，CD4/CD8較Hp-亞組降低(P<0.05)；出血亞組患者外周血CD3、CD4水平、CD4/CD8較未出血亞組降低(P<0.05)。大便隱血試驗陽性患者轉(zhuǎn)陰后外周血CD3、CD4、CD8、CD19、CD56、C3、C4水平較治療前升高，IgG、IgM水平較治療前降低(P<0.05)。結(jié)論消化性潰瘍患者存在免疫功能調(diào)節(jié)紊亂，幽門螺桿菌感染可促使機體產(chǎn)生強烈的免疫反應(yīng)，急性出血后免疫功能處于抑制狀態(tài)，止血后免疫功能有所恢復(fù)。

消化性潰瘍是一種多發(fā)病、常見病，好發(fā)于胃和十二指腸。免疫因素是否參與了消化性潰瘍的發(fā)生與發(fā)展，是目前國內(nèi)外研究的焦點之一[1-2]，且一直存在爭議，免疫功能調(diào)節(jié)具有雙向性，其亢進(jìn)或低下與消化性潰瘍的關(guān)系尚不清楚[3]。為此，本研究檢測消化性潰瘍患者外周血細(xì)胞免疫指標(biāo)及體液免疫指標(biāo)，觀察消化性潰瘍患者與體檢健康者、是否感染幽門螺桿菌及是否出血與免疫功能指標(biāo)的關(guān)系以及出血恢復(fù)期免疫功能指標(biāo)的變化，探討消化性潰瘍與細(xì)胞免疫指標(biāo)及體液免疫指標(biāo)之間的關(guān)系。

3討論

淋巴細(xì)胞在免疫應(yīng)答中起核心作用，T淋巴細(xì)胞亞群是構(gòu)成機體免疫防御系統(tǒng)的重要細(xì)胞，免疫球蛋白及補體與淋巴細(xì)胞同樣是機體免疫防御機制的重要組成部分，在體液免疫中起著重要作用。目前消化性潰瘍病因尚未完全明了，較為明確的病因是幽門螺桿菌感染，幽門螺桿菌感染是否使機體免疫功能紊亂，導(dǎo)致消化性潰瘍的發(fā)生，目前的研究結(jié)果并不一致[1-3]。

【Abstract】ObjectiveTo investigate the changes of cellular immune function and humoral immune function in peripheral blood of patients with peptic ulcer and the clinical significance.MethodsFrom January 2014 to January 2015,we enrolled 122 patients who were definitely diagnosed as peptic ulcer in the Affiliated Hospital of Hangzhou Normal University as ulcer group,and enrolled 70 healthy people who received physical examination as control group.According to whether infection of helicobacter pylori occurred,the patients in ulcer group were divided into helicobacter pylori positive subgroup(Hp+subgroup)(n=85) and helicobacter pylori negative subgroup(Hp-subgroup)(n=37),and were divided into bleeding subgroup(n=58) and non-bleeding subgroup(n=64) according to whether bleeding occurred.The indexes of cellular immune function(including CD3，CD4，CD8，CD4/CD8，CD19and CD56) and indexes of humoral immune function(including IgG，IgA，IgM，IgE，C3 and C4) in peripheral blood were detected.In bleeding subgroup,30 patints who had positive results in fecal occult blood testing received reexamination of the indexes of immune function and humoral immune function in peripheral blood after fecal occult blood testing showed negative results.ResultsThe levels of CD3，CD4，CD4/CD8，CD19，CD56，C3 and C4 in peripheral blood were lower in ulcer group than those in control group,the levels of IgG in peripheral blood was higher in ulcer group than that in control group(P<0.05)；the levels of CD3，CD4，CD8，CD19，IgM and IgE in peripheral blood were higher in Hp+ subgroup than those in Hp- subgroup，the CD4/CD8 in peripheral blood was lower in Hp+ subgroup than that in Hp- subgroup(P<0.05)；the levels of CD3，CD4 and CD4/CD8 in peripheral blood were lower in bleeding subgroup than those in non-bleeding subgroup(P<0.05).The levels of CD3，CD4，CD8，CD19，CD56，C3 and C4 in peripheral blood were higher in patients who had positive results in fecal occult blood testing first but later turned negative than those before treatment(P<0.05);the levels of IgG,IgM in peripheral blood were lower in patients who had positive results in fecal occult blood testing first but later turned negative than those before treatment(P<0.05).ConclusionPatients with peptic ulcer have disorder in immune function,and infection of helicobacter pylori may induce strong immune reactions.Acute hemorrhage may cause a inhibitory state of immune function which may be relieved after hemostasis.
