RESUMEN
AIM To establish an HPLC method for the simultaneous content determination of 5-caffeoylquinic acid,chlorogenic acid,4-caffeoylquinic acid,caffeic acid,1,3-dicaffeoylquinic acid,scutellarin,isochlorogenic acid B,3,5-dicaffeoylquinic acid,apigenin-7-O-glucronide and 4,5-dicaffeoylquinic acid in Dengzhan Xixin Injection [Erigeron breviscapus (Vaniot.) Hand.-Mazz].METHODS The analysis of aqueous extract of this drug was performed on a 30 ℃ thermostatic Inertsil(R) ODS-3 column (250 mm × 4.6 mm,5 μm),with the mobile phase comprising of 0.4％ phosphoric acid-acetonitrile flowing at 0.9 mL/min in a gradient elution manner,and the detection wavelength was set at 327 nm.RESULTS Ten constituents showed good linear relationships within their own ranges (r≥0.999 0),whose average recoveries were 94.11％-100.64％ with the RSDs of 1.12％-2.77％.CONCLUSION This simple,accurate and reproducible method can be used for the quality control of Dengzhan Xixin Injection.
RESUMEN
Objective To observe the effect of Dengzhan Xixin injection on prevention and intervention of cardiovascular and cerebrovascular system disease of older people caused by metabolic disorder. Method A Group with metabolic syndrome were treated with a mixture of 30～40 mL of Dengzhan Xixin injection in 250 mL of physiological saline by intravenous injections (n=52). A treatment session was one injection once a day for 10～14 days. Each session was repeated every six months for a duration of three years. Cardiovascular and cerebrovascular disease symptoms, and changes of high sensitivity C-reactive protein (hsCRP) were measured compared with the control group (n=50). Results Compared to the control group, the intervention group had improved symptoms, lower occurrence of cardiovascular and cerebrovascular disease and ruduced hsCRP test result. The difference was significant (P
RESUMEN
Objective: To observe the influences of Dengzhan Xixin injection(灯盏细辛注射液) on(vascular) endothelial function and neurological deficit extent in patients with acute cerebral infarction.(Methods): Eightyseven patients with mild to moderate acute cerebral infarction were randomly(divided) into Dengzhan Xixin injection treatment group(treatment group,42 cases) and control group(45 cases) by the random method of envelope and card.The patients in both groups were treated with the same basic therapy.The treatment group was treated with 40 ml of Dengzhan Xixin injection,and the control group was treated with 16 ml of salvia miltiorrhiza injection.The therapeutic course was 14 days in both groups and 2 courses were applied.The changes of circulating endothelial cell count(CEC),the levels of endothelin(ET) and(calcitonin) generelated peptide(CGRP) in plasma as well as neurological deficit were measured and(compared).Results: The plasma CEC,ET in treatment group((8.0?3.6)cells/0.9 ?l and(52.92?(4.52)ng/L)) were significantly lower than those in control group((10.2?3.3)cells/0.9 ?l and(60.12?(3.23)ng/L)),but the plasma CGRP was higher than that in the(control) group on 14 th days((65.23?(1.52)ng/L) vs.(60.12?2.14)ng/L).The differences were significant between the two groups(P
RESUMEN
[Objective] To investigate the effect of Dengzhan Xixin Injection (DXI) combined with photon-autotransfusion therapy in treating diabetic peripheral neuropathy (DPN). [ Methods ] Sixty-one cases of DPN were randomized into 2 groups. Group A ( n=31) was given DXI 30 - 40 mL (intravenous drip, qd) and photon-autotransfusion therapy (once every 2-3 days). Group B (n = 30) was treated with anisodamine 10 - 20 mg (intravenous drip, qd) and vitamin B] 100 mg and B12 500 ?g (intramuscular injection, qd) . Changes of symptoms and signs and neural conductive velocity were observed to evaluate the curative effect after treatment. [ Results ] The markedly effective rate and total effective rate were 58.07% and 93.55% respectively in group A, which were higher than those in group B (16.67% and 63.34% respectively) , the difference being significant ( P
