OBJECTIVE:To establish a method for the contents determination of astragalosidesⅠ,Ⅱ,Ⅲ,Ⅳ,lobetyolin and for-mononetin in Shenqi fuzheng injection. METHODS:HPLC was performed. The detector was evaporative light scattering detector, column was Ultimate XB-C18 with mobile phase of acetonitrile-0.5% formic acid (gradient elution) at a flow rate of 1.2 ml/min, column temperature was 30 ℃,and injection volume was 10 μl. RESULTS:The linear range was 0.62-5.67 μg for astragalosidesⅠ(r=0.999 6),0.78-6.31 μg for astragalosidesⅡ(r=0.999 6),0.36-3.48 μg for astragalosidesⅢ(r=0.999 7),0.81-6.72 μg for as-tragalosides Ⅳ(r=0.999 5),0.82-7.03 μg for lobetyolin(r=0.999 8)and 0.58-6.62 μg(r=0.999 7)formononetin;limit of quan-titation was 1.21,0.15,0.12,0.03,0.12,0.17 μg/ml;limit of detection was 0.35,0.35,0.04,0.01,0.03,0.04 μg/ml;RSDs of pre-cision,stability and reproducibility tests were lower than 2%;recoveries were 95.1%-101.1%(RSD=2.0%,n=9),95.2%-100.7%(RSD=1.9%,n=9),95.8%-100.2%(RSD=1.4%,n=9),96.2%-100.6%(RSD=1.7%,n=9),96.6%-101.2%(RSD=1.4%, n=9) and 95.9%-99.5%(RSD=1.2%,n=9),respectively. CONCLUSIONS:The method is simple and accurate,and can be used for the simultaneous determination of astragalosidesⅠ,Ⅱ,Ⅲ,Ⅳ,lobetyolin and formononetin in Shenqi fuzheng injection.

ObjectiveTo explore the relationship between the changes of neuro-electrophysiology and prognosis in children with Guillain-Barr? syndrome(GBS).MethodsThirty-eight children with GBS were divided into group A(rapid recovery,n=16) and group B(slow recovery,n=22) according to the time required for podosoma motor function recovery,at the same time,they were divided into the better prognosis group(n=22) and the worse prognosis group(n=16),for analyzing the difference between group A and B in terms of age,preceding infections,maximal Hughes grades and neuro-electrophysiology including motor conduction velocity(MCV),distal complex muscle action potential(dCMAP) and F wave,and investigating the related factors with the prognosis of GBS.Results1.MCV of tibial nerve was(40.2?2.53) m/s and(33.4?2.46) m/s in group A and group B,respectively;MCV of peroneal nerve was(45.2?3.23) m/s and(38.3?2.16) m/s in group A and group B,respectively,and the difference between group A and group B was significant(Pa0.05);abnormal rate of F wave(68.42%) was higher than abnormal rate of MCV(42.11%) and dCMAP(42.11%)(Pa

Objective: To study the chemical constituents of Pattra medicine Evodia lepta from Xishuangbanna of Yunnan province, China. Methods: The chemical constituents were isolated and purified by chromatographic techniques, and identified by NMR, MS, and other spectral methods with chemical hydrolysis. Results: In 95% ethanol extract from the leaves of E. lepta, four compounds were isolated and their structures were identified as 2, 4, 6-trihydroxyacetophenone-3, 5-di-C-β-D-glucoside (1), 2, 4, 6-trihydroxy- acetophenone-3, 5-di-C-β (6'-O-E-p-coumaroyl)-D-glucoside (2), 2, 4, 6-trihydroxyacetophenone-3, 5-di-C-β(6'-O-Z-p-coumaroyl)- D-glucoside (3), and 2, 4, 6-trihydroxyacetophenone-3, 5-di-C-β (6'-O-E-cinnamoyl)-D-glucoside (4), respectively. Conclusion: Compounds 2-4 are new compounds named leptabiside A, B, and C, respectively. Compound 1 is obtained from domestic E. lepta for the first time.

OBJECTIVETo evaluate therapeutic effect of acupuncture at "Kaiyin point No. 1" on submucosal hemorrage of vocal cords.

METHODSOne hundred and sixty cases were randomly divided into a test group and a control group. The test group were treated by acupuncture at "Kaiyin point No. 1" with reducing method in reinforcing or reducing method by manipulating the needle in cooperation with the patient's respiration, combined with deep respiratory movement of the glottis laryngeal cavity, once daily; and the control group by spray inhalation of western medicine, once daily, 7 days constituting one therapeutic course.

RESULTSThe cured and markedly effective rate and the total effective rate were 85.0% and 97.5% in the test group and 60.0% and 85.0% in the control group respectively, with a significant difference between the two groups. After treatment of the test group,the acoustical parameters maximum phonation time (MPT), frequency perturbation quotient (FPQ), amplitude perturbation quotient (APQ), ratio of harmonic to noise (H/N) objectively reflected improvement of voice quality.

CONCLUSIONAcupuncture at "Kaiyin point No. 1" as main method is an ideal therapy for submucosa hemorrhage of vocal cords.
