ABSTRACT
OBJECTIVE: To establish the method for content determination of 12 trace elements (Cu, Mn, Mg, Cd, Zn, Fe, Ba, Se, Pb, As, Cr, Ni) in Shiquan dabu pills, and to provide reference for further improvement of its quality control.METHODS: ICP-OES was adopted to detect. Microwave digestion was used for sample pretreatment with digestion power of 800 W; digestion process included heating to 120 ℃ keeping for 3 min, heating to 160 ℃ keeping for 5 min, and finally heating to 180 ℃ keeping for 20 min. PF power was 1 150 W, and pump speed was 50 r/min; the flow rate of atomizing gas was 0. 5 L/min, and that of plasma gas was 12. 0 L/min, detection wavelength of 182. 205-455. 403 nm. RESULTS: Results of 12 elements determination were all within standard range according to national standard substance sampling determination. The liner ranges of Cu, Mn, Mg, Cd, Zn, Fe, Ba, As, Cr and Ni were 0. 2-2. 0 mg/L, those of Se and Pb were 0. 4-4. 0 mg/L (r≥0. 999 5). The detection limits ranged 0. 1-8. 5 μg/L, and limits of quantitation were 0. 3-28. 3 μg/L. RSDs of precision tests were all lower than 1. 00％ (n=6). The average recovery rates were 88. 5％-99. 0％ (RSD were 1. 7％-4. 9％, n=6). CONCLUSIONS: The method is rapid, simple and sensitive, and it can be used for content determination of 12 trace elements in Shiquan dabu pills.
ABSTRACT
Objective To observe the efficacy of the combined treatment of Reduning,budesonide and erythromycin sequential therapy in the treatment of children with mycoplasma pneumonia and investigate its mechanism.Methods 78 children with mycoplasma pneumonia were randomly divided into two groups,each group 39 cases.The control group were given budesonide and erythromycin sequential therapy,and the observation group were given Reduning injection on the basis of the control group.Both groups were treated for 2 weeks.The clinical efficacy was observed,and before and after treatment,the pulmonary function was tested in the both groups.Results The total effective rate of the observation group was 94.87％,which was higher than that of the control group(86.62％)(x2=6.683,P＜0.05);The fever,cough improved,pulmonary rales disappeared,wheeze disappeared and hospital stay time of the observation group were significantly shorter than the control group(all P＜0.01);The FVC,FEV1 and PEF of the observation group were higher than those of the control group(all P＜0.05).Conclusion On the basis of the combined treatment of budesonide and erythromycin,the addition of Reduning injection can improve clinical effect and shorten the symptoms and signs improve time,improve lung function,chich may in association with regulating humoral immunity and reducing the levels of inflammatory cytokines.
