脑偏侧化加速了人类进化,但这种因环境压力所致基因突变的结果,也增加了人类对各种精神疾病的易感性,某些神经、精神疾病患者的非右利手率较正常右利手人群高。近年来的许多研究表明,大脑半球功能偏侧化的变异可能是精神疾病发病的重要环节之一。抑郁发作时大脑半球活化平衡向右脑倾斜,偏执型精神分裂症这一平衡则向左脑过度倾斜,并与躁狂、冲动、暴力和反社会性人格障碍有关,而广泛性焦虑和创伤后应激障碍等则右半球过度活化,精神疾病脑偏侧化变异同时也改变了与情绪、语言信息处理和视-听注意偏向的半球优势特征。精神疾病半球非对称性假说与中医气机升降理论不谋而合,中医认为人体气机运动为左升右降、肝升肺降,气机升降逆乱导致各种病证的发生。本文拟从太极、阴阳、六气、八卦和五行学说,论述"气机升降"中医理论与人体功能偏侧化理论的同一性及其科学性,为揭示中医"气机升降"理论探索新的研究途径。  相似文献

基于精神疾病脑功能非对称性假说,采用重复经颅磁刺激(r TMS)或经颅直流电刺激(t DCS)提高左半球活跃性和/或抑制右半球活跃性可治疗抑郁症;同样,通过r TMS抑制右半球活跃性可治疗焦虑障碍;反之,通过r TMS抑制抑郁症左半球活跃性则加重抑郁症状,通过r TMS兴奋焦虑障碍患者右半球活跃性则加重焦虑症状。r TMS和t DCS在改变半球活跃性的同时,也可改变与之相关的视-听注意偏向。针刺治疗抑郁症可发挥类似r TMS和t DCS的生物学效应,并且左、右单侧肢体经穴针刺增高或降低同侧半球运动皮层兴奋性的效应与人体气机左升右降方向一致,因此,无论在理论上还是和实践上,脑功能非对称性假说与中医气机升降理论不谋而合。  相似文献

中医理论认为,"脑为元神之府",头为"诸阳之会",脑是精髓汇聚和神明生发之处,府精神明有赖于气机推动、经络调畅、脏腑做功、精血生养、升清降浊。情志为狭义之"神明",喜、怒、思(忧)、悲、恐(惊)七种情志活动,分属五行于心、肝、脾、肺、肾。"思"是认知过程,位于其余情绪之中央和归宿。情志与气机升降关系最为密切,喜、怒、惊主动为阳,气机升发外散;悲、忧、恐、思主静属阴,气机内收下沉。现代脑科学研究发现,人类在接受正性和负性情绪信息时左、右半球发生非对称性激活,其激活程度与情绪强度有关。情感性精神障碍和精神分裂症患者左、右半球激活程度的非对称性则发生过度、降低或反转的异常变化。中医"思(脾土)中心"论和"阴阳喜怒"学说与现代心理学认知与情绪的关系、情绪两极性等观点不谋而合。本文基于情志理论、气机升降理论、现代情绪心理学和脑研究成果,论述"情志—气机升降—半球间功能偏侧化"在精神疾病发病机理中的相关性,以扩大中、西医在精神病学领域的共识。  相似文献

<正> 脾胃生理特性与功能脾为脏属阴,胃为腑属阳。以气机升降而言,脾气主升而胃气主降。根据阴阳二气性质,阳气主升阴气主降,但脾胃之气升降与此相反。因为人体脏腑之气属阴者主升,属阳者主降,阴阳之气相互交感,才能发挥其生理功能,故脾气主升而胃气主降。从功能而论,胃主受纳水谷,纳则贵下行故胃  相似文献

6.肺与肝肺主气,司呼吸,肝藏血司疏泄;肺主肃降,肝主升发。以上是两脏各自的主要生理功能及生理活动的特点。而两脏在生理上的联系,主要体现在人体气机升降的调节方面。“气机”,即气的活动,或者说是泛指功能活动。肝气的活动以升发为常,肺气的活动以肃降为顺。升降协调,相互为用,是人体气机调畅,气血调和的一个重要环节。中医有“左肝右肺之说,认为“肝生于左,肺藏于右”。这里左右并非指肝、肺的解剖位置,而是用来代表两脏气机的活动特点,也即“升者左行,降者右行”。因为,从阴阳学说的观点而言,气的运动是上升、下降地循环周流的。上升属…  相似文献

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P < 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (>0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P <0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P < 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.  相似文献

Objective: To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods: SD rats served as both donors and recipients. 4℃ sodium lactate Ringer's was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava (IVC) inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results: Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion: This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.  相似文献

Objective:To investigate the clinical features, pathological characteristics and immunophenotype of solid-pseudopapillary tumor of the pancreas(SPTP). Methods:Nine surgically treated cases of SPTP were retrospectively reviewed. Hematoxylin and Eosin(HE) staining and immunohistochemical staining were used to analyze all cases, and the general clinical data was collected. Results:Six patients were asymptomatic except for a palpable mass. Two patients complained of vague-epigastric pain. One patient appeared jaundice. The tumor was encapsulated and solid tissues alternately with cystic tissues. Histologically, the histological structure of solid portion was pseudopapillary with a fibrovascular core. Tumor cells were uniform and medium-sized which were arranged in sheets ets or nests or pseudopapillary patterns. Immunohistochemical studies demonstrated that SPTP proved positive in vimentin(9/9 cases), AAT(9/9 cases), NSE(9/9 cases), ACT(7/9 cases), CK20(2/9 cases), CgA(1/9 cases), S-100(3/gcases), PR(4/gcases), Syn(3/9 cases) and CD56(5/9cases), negative in CEA and ER. Conclusion:SPTP is a tumor predominantly occurring in young women frequently without special symptoms. This tumor has various characteristical histological patterns with different immunophenotype.  相似文献

Objective: To explore the role of matrix metalloproteinase-1,2 (MMP-1, MMP-2) and tissue inhibitor of matrix metalloproteinases-1 (TIMP-1) in endometriosis. Methods: The eutopic and ectopic endometria from 40 subjects suffering from endometriosis and regular.endometria from 40 subjects (excluding endometriosis) were collected and examined by in situ hybridization technology and western blot assay. Results: Both expressions of MMP-1 and -2 were stronger in ectopic endometrium and eutopic endometrium than in normal endometrium. On the contrary, the expression of TIMP-1 in ectopic endometrium and eutopic endometrium was lower. The differences were significant (P 〈 0.01 ). Moreover, there was no relationship among the expressions of MMP-1, 2 and TIMP-1 in ectopic endometrium. Conclusion: The expressions of MMP-1, 2 and TIMP-1 lose balance and lack of periodic changes in ectopic endometrium , which explains the biological invasive behavior of endometriosis. It was suggested-that regulating the balance between the MMPs and TIMP-1 should be an ideal therapeutic target to endometriosis.  相似文献
