Objective To establish a quality control system of volatile oil of Chunyang Zhengqi capsules. Methods The chromatogram of volatile oil was established by GC method, and the contents of cinnamaldehyde and eugenol were determined. Results In 15 batches of samples, 19 common peaks were identified, and 9 characteristic peaks were selected to establish the characteristic spectrum. The linear ranges of cinnamaldehyde and eugenol were 0.522 - 1.565 mg/ml (r=0.9994) and 3.038 - 9.115 mg/ml (r=0.9997), respectively. The average recoveries were 97.1% and 97.3%, with RSD of 1.5% and 1.4%, respectively. Conclusion The established GC characteristic map and content determination method could control the quality of essential oil in Chunyang Zhengqi capsules qualitatively and quantitatively. The method is accurate and feasible which could be used as the quality control method of essential oil in Chunyang Zhengqi capsules.

Objective To observe the effect of very early intervention with cerebellar fastigial nucleus electrical stimulation and neurodevelopmental treatment on infants of central coordination disturbance(CCD).Methods 86 infants(0～6 months)with central coordination disturbance were divided into intervention group and control group.The intervention group was treated with neurodevelopmental treatment,cerebellar fastigial nucleus(FN)electrical stimulation and family interference.The control group was treated with neurodevelopmental treatment and family interference.The effect of infant was assessment with Gross Motor Function Measure(GMFM)and Gesell Development Test after 3 months treatment.Results The total improved incidence of the intervention group was 95.6%,which was significantly higher than that of the control group(P<0.01).The difference of scores in social,adaptive and motor area improved in the intervention group compared with that of control group(P<0.05).Conclusion Very early intervention with cerebellar fastigial nucleus electrical stimulation can facilitate the development of gross motor,social,adaptive capability of infants with CCD treated with neurodevelopmental therapy.
