Objective To observe the effect of ultra-low frequency transcranial magnetic stimulation on cerebral blood flow in children with spastic diplegia cerebral palsy. Methods 36 cases of spastic diplegia cerebral palsy were divided into control group (n=21) and obsevation group (n=15), 19 healthy children were as normal group. The control group received conventional rehabilitation training. The obsevation group received the ultra-low frequency transcranial magnetic stimulation in addition. All the children received the check of transcranial color Doppler (TCD). Results Several arterials flow velocity was lower, several arterials pulsatility index and resistance index were higher in the obsevation group than in the normal group before treatment (P<0.05). Compared with the control group, the arterial flow of obsevation group improved, pulsatility index and resistance index decreased in some degrees in the obsevation group after treatment (P<0.05). Conclusion The cerebral blood flow is of low velocity and high resistance in spastic diplegia children, while ultra-low frequency magnetic stimulation could improve the condition of cerebral flow.

Objective To establish a new method of quality control for Jie-Er-Yin Lotion.Methods Jie-Er-Yin Lotion and different kinds of agents(without Fructus Cnidii,Cortex Phellodendri Chinensis, Radix Sophorae Flavescentis,excipient agent or all medicinal material agents) were treated with the same approach,then using ~1H-NMR to get all of the chemical component information of the samples and analyze the data from the spectra.Results Analyzing the data with principal component analysis(PCA) by model recognition,the different agents can be distinguished in the scattered plots.Conclusion The ~1H-NMR-PCA is an useful method to identify Jie-Er-Yin Lotion from other preparations and can be used for the quality control of Chinese prepared medicines by simple operation.
