Objective To establish a method of HPLC for determination of rhamnocitrin in Oxytropis falcate Bunge.Methods The HPLC method was used.Chromatographic column:Lichrospher C18(4.6 mm? 250 mm,5 ?m) reversed-phase column;mobile phase:0.4% phosphoric acid in water-methanol(20∶80);flow rate:1.0 mL/min;detective wavelength:350 nm.Results Rhamnocitrin was liner at the range of 4～ 30 ?g(r =0.999 8),and its average recovery rate was 99.7%,RSD=1.4%.Conclusion The method was simple and accurate,so it can be used for the quality control of Oxytropis falcate Bunge.

Objective To investigate the antibacterial activity of the alkaloids extract from Oxytropis falcata Bunge against 9 common pathogens in vitro. Methods Alkaloids was extracted from Oxytropis falcata Bunge. The agar plate dilution method was adopted to evaluate the activity against bacteria of 4 Gram-negative test strains and 5 Gram-positive test strains, while the MIC and MBC were determined by tube double dilution method. Results The alkaloids extract from Oxytropis falcata Bunge had the antibacterial activity against 9 pathogens and there was a good dose-response relationship between sensitivity and concentration. Antibacterial activities against bacillus subtilis and stentrophmomas maltophilia showed stronger than other tested bacteria, the MIC and MBC were 0.95 mg/mL and 1.91 mg/mL, respectively. In other tested bacteria, MIC and MBC were ranged in 1.91-7.63 mg/mL. Conclusion The alkaloids extract showed a broad spectrum of a stronger antibacterial activity against all tested pathogens. Gram-positive strains were more sensitive than Gram-negative strains to the inhibitory effects of the alkaloids extract.

Objective To explore the management of nursing adverse events based on JCI evaluation criteria, and to establish a voluntary, non-punitive nursing adverse event reporting system.Methods From January 2014 to December 2015, 680 hospital nurses implemented JCI standards, revision of nursing adverse events management system, created online of nursing adverse events reporting system, to all nursing staff of adverse event management knowledge training and improvement before the analysis of the implementation of the JCI standard, adverse event reporting process and treatment measures of awareness, took the initiative to report rate, nursing adverse events incidence, patient satisfaction rate.Results Before and after nursing staff of adverse event reporting procedure and disposal method of awareness to improve the rate of 39.43% implementation, nursing staff to take the initiative to report to enhance the rate of 7.54%,the incidence of nursing adverse events to reduce the rate of 0.07%,the patients' satisfaction rate increased by 6.15%,there were statistically significant differences(x2=13.50,10.15,12.09,231.51,all P<0.05).Conclusion Nursing adverse events management constructed based on JCI accreditation standards is helpful to avoid the occurrence of nursing adverse events, to improve the rate of patients' satisfaction to nursing, to create a secure hospital atmosphere.
