【摘要】：目的：觀察黃精多糖對(duì)大強(qiáng)度運(yùn)動(dòng)所致人體T淋巴細(xì)胞免疫功能低下的影響，分析其產(chǎn)生影響的可能機(jī)制，探討減輕運(yùn)動(dòng)性免疫功能低下的新手段。方法：體育學(xué)院無(wú)系統(tǒng)專業(yè)運(yùn)動(dòng)訓(xùn)練經(jīng)歷男生14名，隨機(jī)分為安慰劑組（A組）和黃精多糖組（B組），每組7人。A、B兩組受試者按1g/d劑量分別口服安慰劑和黃精多糖4周后，進(jìn)行一次大強(qiáng)度遞增負(fù)荷跑臺(tái)運(yùn)動(dòng)，于運(yùn)動(dòng)前、運(yùn)動(dòng)后即刻、運(yùn)動(dòng)后24h取受試者肘正中靜脈血各10ml，MTT法檢測(cè)外周血T淋巴細(xì)胞轉(zhuǎn)化指數(shù)（T-LTI），流式細(xì)胞術(shù)檢測(cè)T淋巴細(xì)胞亞群（CD4~+、CD8~+）百分比，雙抗體夾心ABC—ELISA法檢測(cè)Th1、Th2型細(xì)胞因子（IFN-γ、IL-4）、放射免疫法檢測(cè)血漿皮質(zhì)醇（Cor）。結(jié)果：1.A、B兩組受試者運(yùn)動(dòng)前各指標(biāo)無(wú)顯著性差異。2.兩組受試者T-LTI運(yùn)動(dòng)后即刻均低于運(yùn)動(dòng)前，其中A組有非常顯著性差異；運(yùn)動(dòng)后24h，兩組T-LTI均有回升，A組接近運(yùn)動(dòng)前水平，B組稍高于運(yùn)動(dòng)前水平；B組運(yùn)動(dòng)后兩時(shí)相T-LTI均高于A組對(duì)應(yīng)時(shí)相，運(yùn)動(dòng)后即刻有顯著性差異。3.A組運(yùn)動(dòng)后即刻CD8~+明顯高于運(yùn)動(dòng)前，CD4~+、CD4~+/CD8~+明顯低于運(yùn)動(dòng)前，運(yùn)動(dòng)后24h各指標(biāo)有所恢復(fù)，但未達(dá)到運(yùn)動(dòng)前水平，CD4~+/CD8~+仍明顯低于運(yùn)動(dòng)前；B組運(yùn)動(dòng)后兩時(shí)相各指標(biāo)變化趨勢(shì)與A組相同，但變化幅度均明顯小于A組，與運(yùn)動(dòng)前比較均無(wú)顯著性差異，，CD4~+、CD4~+/CD8~+在運(yùn)動(dòng)后24h恢復(fù)到略高于運(yùn)動(dòng)前水平。4.兩組受試者運(yùn)動(dòng)后即刻IFN-γ均低于運(yùn)動(dòng)前，其中A組有顯著性差異，B組運(yùn)動(dòng)后即刻IFN-γ明顯高于A組，運(yùn)動(dòng)后24h，兩組IFN-γ均回升到接近運(yùn)動(dòng)前水平；兩組IL-4運(yùn)動(dòng)后即刻均非常顯著高于運(yùn)動(dòng)前，運(yùn)動(dòng)后24h有下降，但仍高于運(yùn)動(dòng)前水平，其中A組有顯著性差異；兩組IFN-γ/IL-4運(yùn)動(dòng)后即刻非常顯著低于運(yùn)動(dòng)前，運(yùn)動(dòng)后24h有回升，但仍低于運(yùn)動(dòng)前，其中A組有顯著性差異。5.A組Cor運(yùn)動(dòng)后即刻明顯高于運(yùn)動(dòng)前，運(yùn)動(dòng)后24h仍高于運(yùn)動(dòng)前，但無(wú)顯著性差異；B組Cor運(yùn)動(dòng)后即刻和運(yùn)動(dòng)后24h都低于運(yùn)動(dòng)前水平，但無(wú)顯著性差異。結(jié)論：一次大強(qiáng)度跑臺(tái)運(yùn)動(dòng)導(dǎo)致人體T淋巴細(xì)胞免疫功能受到抑制,預(yù)先補(bǔ)充黃精多糖能減輕運(yùn)動(dòng)導(dǎo)致的T淋巴細(xì)胞增殖能力的下降、CD4~+細(xì)胞含量和IFN-γ水平的降低以及CD8~+細(xì)胞含量和IL-4水平的升高，進(jìn)而預(yù)防CD4~+/CD8~+比值、IFN-γ/IL-4比值的下降，表明黃精多糖能有效降低運(yùn)動(dòng)導(dǎo)致的機(jī)體免疫平衡趨向抑制的程度，減輕免疫穩(wěn)態(tài)向體液免疫偏移的程度。其作用機(jī)制可能與黃精多糖能通過抑制運(yùn)動(dòng)后血漿皮質(zhì)醇水平的升高，從而達(dá)到減輕其對(duì)機(jī)體免疫功能的負(fù)調(diào)節(jié)作用有關(guān)。
[Abstract]:Aim: to observe the effect of Polygonatum flavescentis polysaccharides on the immune function of human T lymphocytes induced by high intensity exercise, analyze the possible mechanism of its influence, and explore a new method to alleviate the low immune function caused by exercise. Methods: fourteen male students undergoing sports training without systematic major in physical education college were randomly divided into placebo group (group A) and flavin polysaccharide group (group B). The subjects of group A and group B were given placebo and flavin polysaccharides for 4 weeks according to the dose of 1g/d, respectively. A large intensity incremental load treadmill movement, before the exercise, immediately after the exercise, 24 hours after exercise, T lymphocyte transformation index (T-LTI) and T lymphocyte subsets (CD4 ~ + CD8 ~) percentage were measured by MTT assay and flow cytometry respectively. Double antibody sandwich ABC-ELISA assay was used to detect Th1Th 2 type cytokine, and radioimmunoassay was used to detect plasma cortisol. Results 1. There was no significant difference between the two groups before exercise. The T-LTI of the two groups was lower immediately after exercise than that before exercise, and there was a very significant difference between group A and group A. At 24 hours after exercise, the T-LTI of group A was higher than that of group B at 02:00 after exercise, and the T-LTI of group B was higher than that of group A. There was significant difference immediately after exercise. 3. In group A, immediately after exercise, CD8- ~ was significantly higher than that before exercise, CD4- / -CD8- was significantly lower than that before exercise, and the indexes recovered 24 hours after exercise. However, the change trend of each index in group B after exercise was the same as that in group A, but the change range was obviously smaller than that in group A. There was no significant difference between before exercise and before exercise. CD4 ~ / CD4 ~ / CD8 ~ was slightly higher than that of pre-exercise at 24 h after exercise, and the level of CD4 ~ / CD8 ~ was slightly higher than that before exercise. IFN- 緯 in group A was significantly higher than that in group A immediately after exercise, and IFN- 緯 in group B was significantly higher than that in group A immediately after exercise. At 24 hours after exercise, IFN- 緯 in both groups increased to close to the pre-exercise level. Immediately after exercise, IL-4 in both groups was significantly higher than that before exercise, decreased 24 hours after exercise, but still higher than that before exercise, and there was a significant difference in group A, IFN- 緯 / IL-4 immediately after exercise was significantly lower than that before exercise, and there was a rise 24 hours after exercise. The Cor of group A was significantly higher than that of before exercise and 24 hours after exercise. However, there was no significant difference between group B and group B in Cor immediately after exercise and 24 hours after exercise, but the level of Cor in group B was lower than that in group B immediately after exercise and 24 hours after exercise. But there was no significant difference. Conclusion: the immune function of human T lymphocytes was inhibited by a strong treadmill exercise. Supplementation of flavin polysaccharides in advance could attenuate the decrease of proliferation ability of T lymphocytes induced by exercise and the decrease of CD4- 緯 and IFN- 緯 levels, as well as the increase of CD8- cells and IL-4 levels, thereby preventing the decrease of CD4 ~ / CD8- 緯 / IL-4 ratio. The results showed that the polysaccharide could effectively reduce the degree of inhibition of immune balance and the shift of immune homeostasis to humoral immunity. The mechanism may be related to the inhibition of the increase of plasma cortisol after exercise, which can alleviate the negative regulation of the immune function of the body.
