RESUMEN
Objective To analyze the relation between ~(99)Tc~m-DTPA renal dynamic imaging and pathological changes in patients with lupus nephritis (LN).Methods Ten normal control and 29 patients with LN underwent ~(99)Tc~m-DTPA renal dynamic imaging.The LN patients were divided into two groups:silent LN (SLN) group,18 patients;and obvious LN (OLN) group,11 patients.For each case,glomerular filtration rate (GFR),peak time (t_p),half excretion time (t_(1/2)) and the excretion rate at 20 min (R_(20)) were calculated.Assessment of renal function on the scintigraphic images was evaluated by nuclear medicine physicians.The t-test,Fisher'exact probability and R×C association were used for data analysis.Results There were significant differences between normal people and two goups of LN in tp(t=5.3,9.3,both P＜0.05),t_(1/2)(t=6.9,12.0,both P＜0.05)and R_(20)(t=10.1,12.1,both P＜0.05).As to GFR,there was significant decrease in OLN patients(t=4.1,P＜0.05),but not in SLN patients(t=1.7,P＞0.05).Diagnoses of renal function by renal dynamic imaging were compared with the renal pathological changes (r=0.2273,P＜0.05).Conclusions ~(99)Tc~m-DTPA renal dynamic imaging is useful for evaluation of the early stage renal function for LN patients and to diagnose LN patients with no symptom of renal impairment.It may help to assess the degree of renal parenchymal damage while obviating the need for renal biopsy in these patients.
RESUMEN
<p><b>OBJECTIVE</b>The research on flavonoid in the recent years is extensive, such as Soybeans flavone, Baicalensis flavone, Epimedium flavone. Experiments show the effects of flavonoid is closely related to human health. There are a lot of reports about Ginkcobiobal flavone. In order to make further progress research on ginlcgobiobal flavone, we sum up the articles and reports on ginlcgobiobal flavone in the recent years.</p><p><b>METHOD</b>To searche the articles about ginlcgobiobal flavone studies in the past five years.</p><p><b>RESULT</b>Ginlcgobiobal flavone is not only a vasodilator, but also has the effects of anti-inflammation, analgesia, lowering blood lipids, preventing senile and inhibiting tumor, treating leukaemia, regulating gene and biotransformation.</p><p><b>CONCLUSION</b>Ginlcgobiobal flavone has the potential value for drug research and development.</p>
