摘要:目的从中医“天人相应”动态生命观的角度揭示胃的生理功能特点及其调节机制。方法观察中医五季(春、夏、长夏、秋、冬)变化下,对照组和松果腺摘除模型组大鼠胃黏膜IL-2、IL-10、PGE2和SIgA含量改变情况。结果1)正常对照组大鼠胃黏膜IL-2水平在春季[(43.41±6.34) ng/g]呈现出高峰(P<0.05);2)对照组大鼠在长夏季节胃黏膜IL-10[(15.56±2.59 ) ng/g]、PGE2[(47.23±23.09) ng/g]和SIgA[(3.62±1.50) μg/mg]水平最高,且与夏、冬季相比,均有统计学意义(P<0.05,P<0.01,P<0.01);3)模型组大鼠摘除松果腺后,胃黏膜IL-2、IL-10的季节性节律消失,胃黏膜PGE2、SIgA含量变化不明显。结论胃黏膜的免疫因子存在季节性节律变化,长夏季节胃黏膜免疫功能较其他季节存在着显著的差异,而且松果腺在这一变化中起了重要的调节作用。

Abstract:ObjectiveTo reveal the physiological features and regulation mechanism of stomach from the perspective of TCM “Corresponding between man and nature”,a dynamic perspective view of life.MethodsRats in control group and model group (with the removal of pineal glands) were raised under TCM five seasons (spring,summer,late summer,autumn,winter) and content changes of IL-2,IL-10,PGE2 and SIgA in gastric mucosa were observed.Results1)IL-2 level of rat gastric mucosa in control group showed a peak(43.41±6.34 ng/g) in the spring (P<0.05);2)IL-10,[(15.56±2.59) ng/g] PGE2[(47.23±23.09) ng/g)]and SIgA[(3.62±1.50) μg/mg] in gastric mucosa of the control rats all reached the highest level in late summer,and were statistically significant (P<0.05,P<0.01,P<0.01 respectively) compared with those in summer and winter;3)After model rats’ pineal glands being removed,seasonal rhythms of IL-2 and IL-10 in gastric mucosa disappeared,while the content of gastric mucosa PGE2 and SIgA did not change significantly.Conclusion1)Seasonal changes of gastric mucosal immune factors exist;2)There are significant differences in the gastric mucosal immune function in late summer compared to other seasons;3)Pineal gland plays an important regulatory role in these changes.

Keywords:TCM five seasons;late summer;gastric mucosal immune;pineal gland

中医“五脏应时”理论体现了机体自发地、自组织地去适应环境的过程[1],而这种从五季(春、夏、长夏、秋、冬)的动态变化中认识人体脏腑功能是中医生命观的特点之一。各项实验研究也证实其具有临床价值[2]。胃为“仓廪之官”,具有重要的临床意义。现代流行病学调查[3-6]也表明,许多胃的疾病均存在季节性发病的特点,因此有研究者相应地提出发病季节等因素是慢性胃炎研究的重要考虑因素[7],但其中的机制尚不清楚。免疫功能在维持机体健康方面发挥着重要的作用,而胃的黏膜免疫的变化也直接影响着胃的免疫功能[8]。因此本研究通过观察胃黏膜IL-2、IL-10、PGE2和SIgA等相关免疫因子在中医五季的变化特点,以及与季节调节密切相关的松果腺的影响,以期从中医“天人相应”动态生命观的角度揭示胃的生理功能特点及其调节机制。……
