远红外陶瓷微珠干预对急性损伤大鼠LZM、MPO、IL-8和IL-10指标影响的研究
利用远红外陶瓷微珠作为干预手段,对大鼠肌肉急性损伤后进行恢复治疗,探讨其对骨骼肌血清炎症指标LZM、MPO和免疫学IL-10、IL-8指标的影响.将88只SD雄性大鼠分为A组安静对照组; B组模型组; C组模型+热水组; D组模型+陶瓷微珠组,大鼠急性损伤造模成功后自然休息48 h后,各组实验大鼠按照设计分别取干预后第3 d、4 d、6 d、7 d时相点数据进行组内、组间分析.结果:(1)干预后第3 d,D组血LZM、IL-10恢复后各时相水平均显著高于自然恢复B组与模型C组(P <0. 05);(2)干预后7 d,D组血MPO、IL-8恢复水平均显著低于自然恢复B组与模型C组(P <0. 01).结论:(1)远红外陶瓷微珠干预下,发现降低了MPO水平而提升了LZM水平,说明干预后急性损伤炎性细胞对损伤肌肉的破坏进一步减小;(2)远红外陶瓷微珠干预可提升IL-10浓度水平和降低IL-8的浓度水平,验证其影响炎症反应过程,促进急性损伤的快速恢复.福建省自然科学基金资助项目(2016J01404);;莆田学院育苗基金资助项目(2017014);莆田学院国家基金预研资助项目(2016076);;国家体育总局科技服务资助项目(2017HT008
Experimental study on effect of Changrun Formula in regulating expression of AQP3 and AQP9 in colon mucosa of functional constipation rats
目的:观察肠润方对功能性便秘模型大鼠结肠黏膜AQP3、AQP9表达的影响,探究其调控AQP3、AQP9表达的分子机制。方法:60只SD大鼠随机分为空白组、模型组、阳性对照组(麻仁丸组)、肠润方组、肠润方联合P38MAPK抑制剂SB203580组。用复方地芬诺酯制造大鼠便秘模型,采用免疫组织化学及实时荧光定量PCR(q RT-PCR)检测大鼠便秘模型近端及远端结肠黏膜AQP3、AQP9的表达;Western Blot检测信号传导通路相关分子P38MAPK及P-P38MAPK的表达。结果:造模成功后,模型组近端结肠黏膜AQP3表达较空白组明显上升,而远端结肠黏膜AQP9表达较空白组明显下降(t值分别为3.148和7.069,P值均0.05)。肠润方联合P38MAPK抑制剂SB203580治疗后,近端结肠黏膜AQP3 m RNA水平显著上升(t=5.922,P0.05). The level of AQP3 m RNA in proximal colonic mucosa was significantly increased(t=5.922, P<0.01), and AQP9 m RNA was significantly decreased in distal colonic mucosa(t=4.038, P<0.01); The relative expression of P-P38/P38 protein was significantly decreased(t=19.419, P<0.01). Conclusion: The therapeutic action ofChangrun Formula on functional constipation rat models might through inhibiting the expression of AQP3 in proximal colon, and accelerating on expression of AQP9 in distal colon, and the regulating mechanism might relate with the inhibition on P38 MAPK and AKT phosphorylation.福建省自然科学基金项目(No.2012D043)~
