RESUMEN
OBJECTIVE:To investigate the significance of tacrolimus blood concentration monitoring to the therapy of mem-branous nephropathy. METHODS:41 patients with membranous nephropathy received tacrolimus,and the blood concentration of ta-crolimus reached to steady state. The trough concentration of tacrolimus was determined by EMIT. The patients were followed up, and clinical therapeutic efficacies were recorded. The relationship of blood concentration of tacrolimus with clinical efficacy was evaluated by SPSS 16.0 software. RESULTS:The blood concentration of tacrolimus was(7.47±2.74)ng/ml in complete remission (CR)group,(5.72±1.19)ng/ml in partial response(PR)group,and(3.30±1.08)ng/ml in no response(NR)group,with total remission rate of 75.61%. The blood concentration of CR group was the highest,followed by PR group and NR group,there was statistical significance among 3 groups(P<0.05). CONCLUSIONS:The clinical efficacy of tacrolimus in the treatment of nephrot-ic syndrome is correlate to the blood concentration intimately. Trough concentration monitoring of tacrolimus has important signifi-cance to the treatment of membranous nephropathy.
RESUMEN
<p><b>OBJECTIVE</b>To develop a method for elucidating " chromatography-efficacy" relation of the extract of Zanthoxylum nitidum on the gastric cancer cells.</p><p><b>METHOD</b>After obtaining the tumor inhibition rate and fingerprint peak data through MTT and HPLC, "chromatography-efficacy" relation was established by an appropriate statistical method.</p><p><b>RESULT</b>The gastric cancer "chromatography-efficacy" relation of Z. nitidum was established by step-back technique.</p><p><b>CONCLUSION</b>The "chromatography-efficacy" relation has statistically significant and practical significance, so it has reference value in some way.</p>
