RESUMO
To develop a method for the determination of 18 elements such as Pb, Cu, As, Hg, Mn, Ni, & Tl in Panax notoginseng,Bulbus fritillariae thunbergii,Coix seed, Resina draconis, and to control the contents of heavy metal elements in Sanjie Zhentong Capsule, the samples were digested by microwaves and then analyzed by appropriate determination parameters through ICP-MS, with the internal standard method to improve the matrix effect and interference. The correlation coefficientR2≥ 0.999 2. The lowest limits of quantification were from 0.002 8 to 0.54 μg·L-1. The experiments had better repeatability, while the recovery values ranged from 73.01% to 109.13%. The method is simple, accurate and high sensitive, and it can be used for the determination of rapid monitoring the multi-elements inPanax notoginseng, Bulbus fritillariae thunbergii, Coix seed,and Resina draconis.
RESUMO
Henoch Sch?nlein purpura( HSP) is a vasculitis of primary systemic vascular lesions of aller-gic diseases in children. Henoch Schonlein purpura nephritis( HSPN) is the most common allergic purpura sec-ondary renal disease,hematuria and(or)proteinuria of allergic in purpura the course(the most six months) can make diagnosis. The clinical manifestations varyies in severity,and the incidence has increased year by year,the incidence may be related to infections, allergies, immune abnormalities, immune damage and so on. So raising awareness of children nephritis,early diagnosis,early treatment has a great impact on the prognosis of children.
