摘要
目的:探讨磁共振IDEAL-IQ序列评价"接力赛"电针法对腹型肥胖女性肝脏脂肪含量影响的价值。方法:20例腹型肥胖女性随机分为对照组和电针治疗组,其中对照组9例,电针治疗组11例,电针治疗组采用"接力赛"电针法进行治疗,每周治疗3次,共治疗3个月。治疗前后,20例受试者均行腹部MRI扫描,采用基于最小二乘法估计和不对称回波迭代分解水和脂肪的脂肪成像(IDEAL-IQ)序列,测量每位受试者的质子密度脂肪分数(PDFF)值,记录治疗前后20例受试者的身高、体重并计算身体质量指数(BMI)。结果:治疗前,对照组与治疗组的BMI差异无统计学意义(P>0.05);对照组检查前、后的BMI差异无统计学意义(P>0.05);治疗后治疗组的BMI降低,与治疗前差异有统计学意义(P<0.05)。治疗组各肝段(Ⅰ、Ⅱ、Ⅲ、ⅣA、ⅣB、Ⅴ、Ⅵ、Ⅶ、Ⅷ)的PDFF值较治疗前均有所下降,且Ⅱ、Ⅲ、ⅣA、ⅣB、Ⅴ、Ⅵ、Ⅶ、Ⅷ段的PDFF值与治疗前相比差异有统计学意义(P值均<0.05),各肝段的PDFF值分别下降2.5%、3.1%、2.1%、4.2%、1.8%、2.1%、2.3%、2.2%、3.2%。对照组各肝段治疗后与治疗前相比,PDFF差异均无统计学意义(P值均>0.05)。结论:"接力赛"电针法可以有效降低腹型肥胖女性的肝脏脂肪含量,磁共振IDEAL-IQ序列可以评价肝脏各段脂肪含量的变化。
Objective：To evaluate the efficacy of electroacupuncture （EA） therapy on liver fat content in abdominal type obese women by MRI IDEAL-IQ sequence. Methods： A total of 20 cases of abdominal type obese women were randomly divided into EA group （n = 11） and control group （n = 9）. In EA group,patients were treated with EA therapy 3 times per week for 3 months. Height and body weight were recorded for all the subjects and their body mass index （BMI） was measured as well. Magnetic resonance imaging was performed on all subjects before and after treatment. Hepatic proton-density fat fraction （PDFF） was measured on images of IDEAL-IQ with three regions of interest within each liver segment. Results：Before treatment,there was no significant statistical difference in BMI between control group and EA group （P 〈 0.05）. There was no significant statistical difference in BMI before and after examination in control group; however, BMI decreased significantly after treatment in EA group （P 〈0.05）. In EA group, the PDFF decreased in all liver segments （2.5% ,3.1% ,2.1% ,4.2% ,1.8% ,2.1% ,2.3%,2.2% ,3.2%） ,and significantly decreased in all segments except segment I （P〈0.05）. However,in control group,the difference of PDFF was insignificant （P 〈 0.05） before and after treatment. Conclusion： EA therapy can effectively reduce liver fat content in obese women, and the IDEAL-IQ sequence can be used to evaluate the change of fat content in each liver segment.
