目的探讨不同年龄段成人脑血流量随体质量、性别等不同而出现的差异性改变,总结脑血流量不断发展的特征.方法 360例查体者,按照性别分成两组,应用TCD检测血流速度；按不同年龄段分成五组,应用TCD检测血流速度；按照体质量指数分成四组,应用TCD检测血流速度.结果 196例男性体检者,平均脑血流量(969.37±117.54) ml/min;164例女性体检者,平均脑血流量(987.76±114.34)ml/min,两组比较差异无统计学意义(P＞0.05).不同年龄段脑血流速度血流速度有差异,其中20～ 29岁组与30～39岁组差异无统计学意义(P ＞0.05)；40～49岁组、50 ～ 59岁组、60～69岁组、＞70岁组较前两者显著下降(P＜0.05)；后四组之间有差异有统计学意义(P＜0.05).超重组与肥胖组显著低于过轻组与正常组(P＜0.05).结论 TCD可敏感而准确地反映人脑的血流动力学变化,对脑血管疾病的早期诊断、预防、治疗、随访有重要意义.

Objective To explore the different changes of the adult cerebral blood flow with ages,different weight and gender,to summarize the changing characteristics of cerebral blood flow.Methods 360 cases of examination were divided into two groups according to gender,and were divided into five groups at different ages,and were divided into four groups according to body mass index,using TCD detector blood flow velocity.Results 196 cases of male physical examination,the mean cerebral blood flow was (969.37 ± 117.54)ml/min;the 164 females physical examination,the average cerebral blood flow was (987.76 ± 114.34)ml/min,there was no statistically significant difference (P ＞ 0.05).Different ages cerebral blood flow velocity were different,20 to 29-year-old group and the 30 to 39-year-old group had no significant difference (P ＞ 0.05) ;40 to 49-year-old group,50 to 59 years,60 to 69 years old ＞ 70 age group significantly declined compoued with the first two groups,there was significant difference (P ＜ 0.05) ;there were significant difference between the four groups (P ＜ 0.05).Overweight and obese group were significantly lower than the light and the normal group,there was a statistically significant difference (P ＜ 0.05).Conclusion TCDcan be a sensitive and accurate hemodynamic changes in the human brain,and is very important in the early diagnosis,prevention,treatment,and follow-up of cerebrovascular disease.
