Objective To assess the value of quantitative color Doppler sonography in patients with systemic lupus erythematosus (SLE). Methods The right renal in 21 patients with SLE and 22 normal subjects were examined with Philips IU22 ultrasonic diagnostic device. Resistence index (RI) of interlobar artery and interlobular artery were measured with color Doppler sonography, vascularity index (VI), flow index (FI) and vascularization flow index (VFI) which reflecting the renal cortical blood flow were calculated with quantitated analysis software. All the parameters between two groups were compared and analyzed. Results The color signals of renal cortical blood flow in patients with SLE were inferior to those of the normal group, especially in the area near the edge of renal. No statistical difference of RI was found between the two groups (P>0.05), while VI, FI and VFI in SLE group were significantly lower than those of the normal group (VI, VFI, P<0.01, FI, P=0.01). Conclusion Color Doppler sonography combined with blood flow quantitative technique provide a helpful, sensitive and convenient tool to detecte the renal changes in SLE patients.

Objective To design and apply the nursing quality management system of our hospital in order to strengthen nursing informationization construction, and improve management efficiency of nursing quality. Methods Based on the original design of nursing management system, the quality management system which take nursing as the main part was researched and developed by us and applied to the clinical. Our nursing management department combined PDCA cycle with our nursing quality management, and developed nursing unit quality evaluation criteria, each ward were checked by evaluating group of nursing quality management, the analysis and corrective measures should be asked to put forward. Results From July to December in 2016, nursing accidents, pressure ulcer, tumbling, pipe slippage, medication, errors and all adverse events incidence compared with 2015 year dropped 60.00％(0.03/0.05), 43.33％ (0.13/0.30), 50.00％ (0.04/0.08), 40.00％ (0.04/0.10), 33.33％ (0.01/0.03),43.85％(0.25/0.57), and all adverse events in 2016 compared to the period of 2015 had statistically difference (χ2=7.266, P<0.05), and the problem rectification rate was significantly higher than before(χ2=-3.212--2.637,P<0.05). Conclusion The construction and application of nursing quality management system realized the informationization and resource sharing of nursing quality management, it will help the quality of management to upgrade continuously and improve the efficiency of nursing quality management.
