目的 :观察头颅磁共振成像 (MRI)定位围针对中风患者血液流变学的影响。方法 :将确诊的 40例中风偏瘫病人随机分为两组

其中 2 0例用MRI定位围针法治疗

另 2 0例用传统头针法治疗

对治疗前后患者血液流变学变化进行比较。结果 :两种针法对中风患者的血液流变学多项指标均有改善作用

经统计学处理发现

MRI定位围针法在改善血液流变学方面优于传统头针组

两组比较差异有显著性意义 (P <0 0 5)。结论 :MRI定位围针法治疗中风偏瘫具有肯定的疗效Objective:To observe the therapeutic effect of magnetic resonance imaging (MRI) location guided surrounding needling on hemorheology of stroke patients. Methods: 40 stroke patients suffering from hemiplegia were randomly and evenly allocated into surrounding needling group and conventional scalp acupuncture group. In the former group

after locating the cerebral focus with MRI scanning

filiform needles were inserted into the scalp around the focus projecting region with every two needles being about 2?cm apart and twirled rapidly (180～200 times/min) for 2?min. In the later group

Motor Area (MS 6) and Sensory Area (MS 7) on the contralateral side of the focus were punctured and stimulated with the same methods. In addition

some other body acupoints were used in combination according to pattern identification. Indexes of hemorheology of both groups were determined by using NXE 1 Viscosimeter. Results: The mean values of the whole blood viscosity (ηb)

plasma viscosity (ηp)

erythrocyte sedimentation rate (ESR)

Hematocrit (HCT)

reduced viscosity (RV)

erythrocyte aggregation index (RAI)

index of rigidity (IR)

blood sedimentation formula K and total integral of healthy people ( n =30) were all significantly higher than those of the 40 stroke patients ( P <0.01). Self comparison of each group displayed that after 30 sessions of treatment

ηb

ηp

HCT

RV

RAI

IR and total integral in surrounding needling group; and ηb

ηp

HCT

RV

RAI and total integral in conventional scalp acupuncture group all lowered significantly ( P <0.05). Comparison between two groups showed that the effects of surrounding needling on ηb

HCT

IR and total integral were significantly superior to those of conventional scalp acupuncture group ( P <0.05)

displaying that surrounding needling is apparently better than conventional scalp acupuncture in improving some indexes of hemorheology of stroke patients. Conclusion: MRI guided surrounding needling is significantly superior to conventional scalp acupuncture in bettering hemorheology of stroke patients.
