Effects of acupuncture on declined cerebral blood flow,impaired mitochondrial respiratory function and oxidative stress in multi-infarct dementia rats

Brain energy disorders and oxidative stress due to chronic hypoperfusion were considered to be the major risk factors in the pathogenesis of dementia. In previous studies, we have demonstrated that acupuncture treatment improved cognitive function of VaD patients and multi-infarct dementia (MID) rats. Acupuncture therapy also increased the activities of glycometabolic enzymes in the brain. But it is not clear whether acupuncture treatment compensates neuronal energy deficit after cerebral ischemic through enhancing the activities of glucose metabolic enzymes and preserving mitochondrial function, and whether acupuncture neuroprotective effect is associated with activations of mitochondrial antioxidative defense system. So, the effect of acupuncture therapy on cognitive function, cerebral blood flow (CBF), mitochondrial respiratory function and oxidative stress in the brain of MID rats was investigated in this study. The results showed that acupuncture treatment significantly improved cognitive abilities and increased regional CBF of MID rats. Acupuncture elevated the activities of total SOD, CuZnSOD and MnSOD, decreased the level of malondialdehyde (MDA) and superoxide anion, regulated the ratio of reduced glutathione (GSH) and oxidized glutathione (GSSG) in mitochondria, and raised the level of the respiratory control index (RCI) and P/O ratio and the activities of mitochondrial respiratory enzymes of MID rats. These results indicated that acupuncture treatment improved cognitive function of MID rats; and this improvement might be due to increased CBF, which ameliorated mitochondrial dysfunction induced by ischemia and endogenous oxidative stress system of brain.     

α1-肾上腺素受体介导交感神经对机体调节及针灸效应的研究情况分析

为明确近30年α_1-AR(a1-Adrenoceptor)介导交感神经对机体生理病理变化及针灸效应的研究情况,本文查阅CNKI数据库及Pubmed数据库,对近30年关于α_1-AR介导的交感神经对机体生理病理影响及针灸效应的研究情况进行系统回顾。发现α_1-AR不但介导交感神经对心脏的变力变时效应,以及血管平滑肌、膀胱括约肌和子宫平滑肌的收缩等生理效应的调节,还介导了心律失常、心肌肥大等病理过程,此外,α_1-AR还介导了针刺信号的传导,而且针刺还可以调节交感神经张力。说明机体的许多生理病理改变与α_1-AR及亚型的变化有密切关系,因此,深入研究α_1-AR将有助于阐释机体的生理病理机制,也为有效药物提供理论依据和相应的药理模型;对经脉穴位上α_1-AR的深入研究,有助于经络实质的探讨及针刺效应物质基础研究。

紫癜清颗粒联合针刺治疗对HSP患者调节性T细胞的影响

目的:探讨紫癜清颗粒对过敏性紫癜(HSP)患者的临床疗效及外周血CD4+CD25+Foxp3+表达的影响。方法:纳入120例确诊为HSP患者,随机分为两组,治疗组予以紫癜清颗粒联合针刺治疗,对照组予以强的松联合扑尔敏治疗;两周为一个疗程,共观察4周,采用流式细胞术检测外周血CD4+CD25+Foxp3+的表达。结果:治疗组有效率与对照组相当(P0.05),但复发率较对照组减低(P0.01);治疗组治疗后患者外周血CD4+CD25+Foxp3+比例增高,与对照组治疗后患者外周血CD4+CD25+Foxp3+的表达相比,无统计学意义(P0.05),但表达比例较对照组高。结论:紫癜清颗粒联合针刺治疗过敏性紫癜既可以明显改善患者临床症状,还能降低复发率;治疗后CD4+CD25+Foxp3+明显升高,说明调节性T细胞可能参与了HSP的发病,也可能是紫癜清颗粒联合针刺治疗HSP有效的原因。     

Mast Cell-Nerve Cell Interaction at Acupoint: Modeling Mechanotransduction Pathway Induced by Acupuncture

Mast cells are found abundant at sites of acupoints. Nerve cells share perivascular localization with mast cells. Acupuncture (mechanical stimuli) can activate mast cells to release adenosine triphosphate (ATP) which can activate nerve cells and modulates pain-processing pathways in response to acupuncture. In this paper, a mathematical model was constructed for describing intracellular Ca²⁺ signal and ATP release in a coupled mast cell and nerve cell system induced by mechanical stimuli. The results showed mechanical stimuli lead to a intracellular Ca²⁺ rise in the mast cell and ATP release, ATP diffuses in the extracellular space (ECS) and activates the nearby nerve cells, then induces electrical current in the nerve cell which spreads in the neural network. This study may facilitate our understanding of the mechanotransduction process induced by acupuncture and provide a methodology for quantitatively analyzing acupuncture treatment.
