| Objective Explore the correlation between the systemic lupus erythematos-us fingertip peripheral blood flow and renal damage.Method (1) My first visit in52patients with SLE, according to the1982American College of Rheumatology (ACR) diagnostic criteria for SLE’s be divided into LN group (24-hour urinary protein excretion≥0.5g) and SLN group (24-hour urineprotein<0.5g); LN group30cases and SLN group of22cases. Select a control group of50cases. Were detected by the right proper palmar digital artery peak systolic velocity (PSV), diastolic velocity (EDV) and resistance index of the end of (Rl), and pairwise comparison analysis.(2) Detected in SLE patients with middle finger artery RI with24-hour urine protein for correlation analysis.Results (1) Normal proper palmar digital artery can clearly show the blood flow signal, the blood flow beam edge for finishing. Patients with SLE middle finger artery blood flow signals to reduce blood flow interrupted, the more severe was the "star-shaped".(2) Control group of proper palmar digital artery PSV (26.64±7.86) cm/s, EDV (12.11±4.35) cm/s, and RI0.55±0.07; LN, group of proper palmar digital artery the PSV (19.45±6.31) cm/s, EDV (4.73±2.2) cm/s, and RI0.76±0.02, of SLN group of proper palmar digital artery the PSV (24.64±13.38) cm/s,, EDV (10.35±7.37) cm/s, RI0.61±0.12, compared with the SLN group and normal group, LN groupPSV, EDV reduce the RI increased, the difference was statistically significant (P<0.05); SLN group and control group, PSV, EDV, no significant difference (P>0.05), the RI increased, the difference was statistically significant (P<0.05).(3) The linear regression equation Y=6.3X-3.2, with SLE group of proper palmar digital artery RI and24-hour urine protein as a positive correlation (r=0.725, P<0.05).Conclusion SLE proper palmar digital artery RI and24-hour urine protein positive correlation can be used as a new reference value in SLE with renal damage early predictor. |
