本文研究右旋糖酐-70(DX-70)和右旋糖酐-40(DX-40)分别对红细胞悬浮液的 6个触变参数的影响。结果表明随着DX-70浓度增加,屈服应力、粘度的非牛顿分量和结构参数平衡值明显升高,提示DX-70能加速红细胞叠连的形成。而DX-40浓度增高时,这些参数变化不大,说明DX-40对叠连的形成影响不大。应用DX-40作为血浆扩容剂,在流变学上更具有优越性。同时,本文也证明结构参数平衡值是叠连形成的相对数量和程度的良好指标。而叠连解体的表观速率常数是叠连解体难易的指标,这为血液流变学今后的研究提供了重要参数。  相似文献

目的研究短暂性脑缺血发作患者血液流变学改变及其临床意义。方法将50例短暂性脑缺血发作患者的血液流变学指标与正常对照组进行比较分析。结果短暂性脑缺血发作组的各项血液流变学指标高于对照组(P<0.05),红细胞压积和纤维蛋白原明显高于对照组(P<0.01)。结论红细胞压积和纤维蛋白原含量增高是造成血液粘度增高的重要因素。  相似文献

目的 探讨椎基底动脉系统短暂性脑缺血发作 (TIA)患者的血液流变学改变及其临床意义。方法对 2 60例椎基底动脉系统TIA患者在末次发作后 3 6小时内进行血液流变学检查。结果TIA组与对照组比较 ,全血粘度、红细胞压积、红细胞聚集性及纤维蛋白原等各项指标均无明显增高 (P >0 .0 5 )。结论椎基底动脉系统TIA的发病因素可能与其血液流变学异常意义不大。  相似文献

利用Low shear-30流变测定仪测定了30例男性脑血栓形成(CTh)患者的全血触变参数,结果显示血浆粘度(η_p)、屈服应力(τ_0)及粘度的非牛顿分量(η_s-μ)明显高于30例男性健康对照组。将患者随机分为二组(各15例),用双盲法分别以藻酸双酯钠(PSS)和低分子右旋糖酐(DX_(40))静脉滴注治疗两周,结果PSS组τ_0、(η_S-μ)和结构参数平衡值(A)明显下降,DX_(40)组的血液触变参数无明显改变,PSS组的临床疗效明显优于DX_(40)组,上述结果表明CTh患者的红细胞聚集明显增多,PSS对红细胞叠连的解聚作用DX_(40)的作用更明显。作者认为这是PSS治疗CTh的临床疗效优于DX_(40)的原因之一;作者提出血液触变参数可作为评定药物疗效的客观指标。  相似文献

血液触变性是指血液粘度依赖于切变率和剪切持续时间的特性。触变参数的测定能全面、动态、定量地反映血液的流变特性。本研究创造了双阶跃剪切测定法,简化了测定手段,提高了准确度。系统测定了314名中国成年人全血触变参数,分析性别和年龄对此参数的影响。首先澄清了国际上认为血液流变参数与性别年龄无关的误解。阐明脑血管病和肺心病患者血液触变参数比健康人有明显的变化,这些参数可作为诊断此疾病的定量指标。用4种药物在体外、2种药物在脑血栓患者体内进行实验,结果不同药物影  相似文献

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.  相似文献

Radiotherapy and chemotherapy are the important modern medical therapies for malignant tumors,yet they can also bring about serious local and systemic toxic side reactions so to decrease the patient;'s life quality,manifested by a series of consumptive symptoms.Having engaged in the combined work of Chinese and western medicine for nearly 50 years,the research fellow Qiu Baoguo in Henan Provincial Academy of TCM has developed his unique views on the TCM study of consumptive syndromes.The author of this essay had once the fortune tO follow Dr.Qiu in clinic,and specially would like to introduce in the following Dr.Qiu's experience in treating consumptive syndromes after radio-chemotherapies for patients with malignant tumor.  相似文献

OBJECTIVE: To observe therapeutic effects of the comprehensive therapy of acupuncture-moxibustion and Chinese Tuina for treatment of insomnia due to deficiency of both the heart and spleen. METHODS: 92 cases were divided randomly into the treatment group (treated by acupuncture-moxibustion and Chinese Tuina) and the control group (treated by acupuncture-moxibustion). RESULTS: The therapeutic effect of the treatment group was obviously superior to that of the control group (the CHI2 test showed P < 0.01). CONCLUSIONS: The comprehensive therapy of acupuncture-moxibustion and Chinese Tuina can give marked therapeutic effects for treatment of insomnia due to deficiency of both the heart and spleen.  相似文献

Evidence obtained from randomized controlled trials (RCTs) has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine (TCM) and results have shown that there is an urgent need for higher quality RCTs on TCM.  相似文献
