目的:探讨血清锰超氧化物歧化酶(Mn-SOD)与颅内良恶性肿瘤的关系。方法:采用黄嘌吟氧化酶法测定了50例脑肿瘤患者血清Mn-SOD活性,并做相关性分析。结果:①星形细胞瘤各组血清Mn-SOD活性均明显低于脑膜瘤组及正常对照组(P<0.01);星形细胞瘤Ⅲ、Ⅵ级组亦明显低于星形细胞Ⅰ、Ⅱ级组(P<0.01);而脑膜瘤组与正常对照组间无显著性差异(P>0.05)。②术后10d星形细胞瘤各组血清Mn-SOD活性较术前明显升高(P<>0.01),而脑膜瘤组较术前无明显改变。③复发性星形细胞瘤Mn-SOD水平较术后10d明显下降(P<0.01),接近于术前水平。结论:随脑肿瘤恶性程度的增加,血清Mn-SOD活性降低;Mn-SOD可作为鉴别脑肿瘤良恶性的辅助指标,并可为早期诊断复发提供帮助。  相似文献

目的探讨磁共振弥散加权成像(DWI)联合波谱分析技术(MRS)应用于临床诊断脑肿瘤的价值。方法回顾性分析资料完整经手术及组织病理学确诊为脑肿瘤的78例患者临床和影像资料。所有患者均行磁共振扫描检查,并予弥散加权成像及波谱分析。比较不同脑肿瘤及其对侧正常区域脑组织的ADC值,记录不同肿瘤代谢物变化情况。结果脑膜瘤平均ADC值明显高于对侧正常区域脑组织ADC值,差异有统计学意义(t=7.96,P0.05);脑转移瘤平均ADC值高于对侧正常区域脑组织ADC值,差异有统计学意义(t=4.94,P0.05);星形细胞瘤平均ADC值为高于对侧正常区域脑组织ADC值,差异有统计学意义(t=9.09,P0.05)。脑膜瘤、脑转移瘤和星形细胞瘤之间ADC值方差分析无统计学意义(P0.05)。I-II级星形细胞瘤与III~IV级星形细胞瘤ADC值差异有统计学意义(t=7.18,P0.05),与对照侧正常组织差异有统计学意义(P0.05)。脑转移瘤、脑膜瘤及星形细胞瘤NAA水平明显低于正常脑组织NAA水平,差异有统计学意义(P0.05);星形细胞瘤NAA/Cho和NAA/Cr值明显高于脑转移瘤、脑膜瘤,差异有统计学意义(P0.05)。结论磁共振弥散成像对脑肿瘤诊断和鉴别诊断有一定价值,ADC值本身并不能很好鉴别实性肿瘤,联合应用波谱分析技术,并结合常规磁共振检查可对常见脑肿瘤进行定性分析和恶性程度分级,为临床诊断和治疗方案制定提供参考依据。  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
