目的:β淀粉样蛋白（β-amyloid precursor protein，β-APP）是已知的参与阿尔茨海默病机制的关键因子。β-APP是否参与难治性癫痫中的病理机制并不清楚。这项研究在于了解β-APP的蛋白在难治性癫痫患者术后颞叶皮质和海马组织中的表达是否异常。方法:免疫荧光法半定量测定难治性癫痫患者术后颞叶皮质和海马组织中的β-APP阳性蛋白的荧光值，并应用统计软件对实验数据进行单因素方差分析。结果:免疫荧光强度值分析结果显示β-APP在耐药性癫痫脑组织中表达较对照组明显增高且有统计学意义。结论:β-APP在难治性癫痫脑组织中异常增高，增高的β-APP可能参与了难治性癫痫的病理机制。
ObjectiveTo explore the relationship between plasma homocysteine level and intracranial artery atherosclerosis in patients with cerebral infarction. MethodsA total of 120 patients with cerebral infarction diagnosed between January and December 2013 were selected.Plasma homocysteine level was analyzed and intracranial artery was detected by DSA. ResultsIntracranial artery atherosclerosis can be found in most of patients with cerebral infarction.Moreover,Plasma Hcy level of patients with large cerebral artery atherosclerosis was much higher than others (P<0.05).The much higher Plasma Hcy level,the severe intracranial artery atherosclerosis were found in internal carotid artery and cerebral middle artery (P<0.05). ConclusionIntracranial artery atherosclerosis is common in patients with cerebral infarction.Occurrence of intracranial artery atherosclerosis is positively correlated with plasma homocysteine level.Plasma homocysteine level may be a risk factor of intracranial artery atherosclerosis in patients with cerebral infarction.
Objective To explore the status of smoking and passive smoking of the population with the high risk of stroke in the community and their attitude towards smoking control. Methods In March 2015, under the direction of Stroke Screening and Prevention Projection, the residents with the high risk of stroke were sought out in Longfeng Community, Suining City, Sichuan Province. And then their status of smoking and passive smoking and their attitude towards smoking control was investigated by Passive Smoking Questionnaire for Adults from National Smoking Control Office. Results A total of 354 residents with the high risk of stroke were sought out, in whom 152 (42.9%) were smokers, and the smoking rate of males (70.1%) and females (1.4%) was significantly different (P<0.001). Those aged 40-49 had the highest smoking rate (55.0%), followed by those aged 50-59 (51.7%), and smokers of the two age groups accounted for 73.0% of all smokers. There was significant difference in smoking rate among different age groups (P<0.001). The smoking rate of those with a lower education level of primary school (57.9%) was the highest, and there were significant differences in smoking rates among the population with different education levels (P<0.001). The smoking rate of the solitary (95.7%) was higher than that of the non solitary (34.9%) (P<0.001). In 202 non-smokers, 67 (33.2%) was suffered from passive smoking, and the rate of passive smoking was 31.3% in males and 62.3% in females with a significant difference (P<0.001). The proportion of the female non-smokers against passive smoking (84.1%) was higher than that of the male non-smokers (57.8%). According to the participants report, 79.9% of participants approved completely non-smoking in hospital, school and public transport, 66.4% approved non-smoking in the office and traffic station, and only 10.2% approved non-smoking in the restaurants. Conclusions The rates of smoking and passive smoking among the population with the high risk of stroke are high, and most of the population are supportive to smoke prohibition in public places except restaurants. The population with a low cultural level is short of smoking harm knowledge.
目的 总结前交通动脉瘤栓塞治疗的经验。 方法 2008年1月－2011年8月，23例前交通动脉瘤患者均在全身麻醉下行动脉瘤内栓塞治疗。其中4例在导丝或导管保护动脉瘤颈情况下行栓塞治疗；1例术中导丝刺破动脉瘤，继续快速填塞至动脉瘤完全栓塞；1例栓塞后弹簧圈突入载瘤动脉，行A1-A2段支架后置入。 结果 23例患者手术技术成功率100%。术后即刻造影，动脉瘤完全栓塞11例，＞90%栓塞8例，＜90%栓塞4例。支架后置入患者术后出现脑梗死，经治疗1个月后康复出院。所有患者临床随访6～24个月，未见再出血。16例患者行全脑血管数字减影血管成像复查，动脉瘤未见复发，其中3例＞90%栓塞、2例＜90%栓塞患者动脉瘤完全闭塞。 结论 弹簧圈栓塞治疗前交通动脉瘤是一种安全、有效的治疗方式。但其技术难度相对较大，需要细致操作。
ObjectiveTo analyze insulin resistance in patients with cerebral infarction and its correlation with plasma homocysteine level. MethodsA total of 100 cerebral infarction patients diagnosed between July 2013 and August 2014 and 100 healthy physical examination subjects were included in our research. The plasma homocysteine level was detected; the levels of fasting plasma glucose and fasting insulin were detected at the same time. ResultsPlasma homocysteine level (34.95±14.55) μmol/L in patients with cerebral infarction was significantly higher than that of the control group (8.84±2.27) μmol/L (P<0.05). Insulin resistance index (6.24±3.15) in patients with cerebral infarction was significantly higher than that of the control group (2.19±0.63) (P<0.05). The plasma homocysteine level in the infarction group with insulin resistance was significantly higher than that in the infarction group without insulin resistance (P<0.05). The plasma homocysteine level in the infarction group without insulin resistance was significantly higher than that of the patients with insulin resistance in the control group (P<0.05). In the cerebral infarction group, insulin resistance index was positively correlated with plasma homocysteine level (r=0.600, P<0.01). ConclusionInsulin resistance and plasma homocysteine level play important roles in clinical cerebral infarction. Improving insulin resistance and decreasing plasma homocysteine level may be effective ways to reduce the incidence of cerebral infarction.
