Journal of Applied Clinical Pediatrics 1986;0(02):-
Objective To search for a way of treating chi1dren's idtopathic nephrotic syndrome (INS) hypoadrenocorticismand its significance. Meethods Thirty-nine patients (31 males and 8 females) with INS were randomly divided into twogroups: 21 patients in tera-peutic group (treated by prednisone, astragali and acanthopanax root) and 18patients in control group (Simply treated by prednisone). 1ml blood was respectively drawn from all thepatients at 8 o'clock (one time before treatment and one time after treatment), the serum cortisol wasdetermined by radioimmunoassay (RIA). Results In control group, the levels of serum cortisol still remained lower than the normal value aftertreatment and the levels after large dosages prednisone treatment were markedly lower than that beforetrea-tment. The values of serum cortisol returned to be normal after treatment in therapeutic group. Conclusion Astragali and acanthopanax root can restore the hypoadrenocorticism in children with INS.

Objective:To explore the degradation effect of gamma-rays radiation sterilization on the effective constituents in Simiao Junyi ointment and study the changes of fingerprint chromatography before and after the sterilization to provide basis for the feasibility of gamma-rays radiation sterilization for Simiao Junyi ointment. Methods:The contents of tetrahydropalmatine and PNS ( Panax Notogin-seng saponins) in Simiao Junyi ointment were determined by HPLC, and the fingerprint chromatography was established. The content changes of tetrahydropalmatine and PNS in Simiao Junyi ointment before and after the gamma-rays radiation sterilization were compared among the same batch and various batches, and the relative retention time and relative peak area in the fingerprint chromatography were also compared. Results:The content of tetrahydropalmatine had no change basically before and after the gamma-rays radiation steriliza-tion(P >0. 05), and there was no change in the total content of PNS (P >0. 05). Comparing the HPLC fingerprint chromatography at 280 nm, the relative retention time had statistically significant change after the gamma-rays radiation sterilization ((P <0.05), while the relative peak area had no statistically significant change(P >0. 05). The number of characteristic peaks reduced by one, namely the C8 characteristic peak disappeared in the pasteurized chromatography, and the areas of C6, C9 and C14 peak decreased significantly, while that of C12 increased. Conclusion:Gamma-rays radiation sterilization have no notable effect on the content of tet-rahydropalmatine and PNS in Simiao Junyi ointment, it can be used for the sterilization of Simiao Junyi ointment.

Objective:To establish an analytical method for HPLC fingerprint chromatography of Simiao Junyi ointment to provide basis for the quality control standard. Methods:The separation conditions were established to obtain the HPLC fingerprint chromatog-raphy of the main ingredients in Simiao Junyi ointment. The conditions were as follows:the chromatographic column was Ultimate C18-ODS(250 mm ×4.6 mm,5 μm), the mobile phase was acetonitrile-0.1% phosphate solution, the flow rate was 1.0 ml·min-1, the detection wavelength was 280 nm, and the column temperature was 35℃. The common peaks in the chromatography were analyzed for their belongings. Results:Gradient elution was performed under the above optimal separation conditions, the constituents in Simiao Ju-nyi ointment were separated from each other perfectly, and the optimal fingerprint chromatography was obtained. Though the methodolo-gy examination, the indicators such as precision, stability and repeatability of the method were all promising, and the fingerprint chro-matography could be seen clearly and was easy to be analyzed. The relationships between Simiao Junyi ointment and the common peaks of four medicinal materials in the fingerprint chromatography were preliminary determined, which provided important basis for the quali-ty control of Simiao Junyi ointment. Conclusion:The HPLC fingerprint chromatography of Simiao Junyi ointment can be used as an a-nalysis method for the quality control of Simiao Junyi ointment, which provides reference for the quality control standard for the finished product.
