OBJECTIVE:To study the enterococcal distribution in clinical samples and their drug resistance to commonly use antibiotic and provide the guidance for rational administration.METHODS : Adopting paper diffusion method to observe the drug resistance of enterococci isolated from clinical samples in our hospital and analyzing their distribution in the samples.RESULTS :Enterococcus faecalis accounts for 44.1% in 227 strains and Enterococcus faecium accounts for 37.9%,the other kinds of enterococci were rare.There was no statistical difference between drug resistance of Enterococcus faecium and that of enterococcus faecalis. Vancomycin was the most potent antimicrobial.Penicillin,ampicillin,and nitrofurantion showed good antibacterial activity against enterococcus faecalis. Enterococcus faecium displayed high-level resistance against antibiotics in addition to glycopeptides.CONCLUSION:Doctor should pay attention to the drug resistance about clinically common pathogenic bacterium. Continual surveillance of resistance rate of enterococcus is important to direct the treatment of enterococcus infections.

AIM: To determine the contents of baicalin, berberine, rhein in Yiqing Capsule(Radix et Rhizoma Rhei, Radix Scutellariae, Rhizoma Coptidis) by HPLC. METHODS: The HPLC system consisted of Kromasil C 18 column (150 mm?4.6 mm, 5 ?m), 0.02 mol?L -1 phosphoric acid (TEA adjusted to pH=6.82)-acetonitrile(40∶11) mixture as mobile phase, detection wavelength at 254 nm, flow rate of 1.0 mL?min -1. RESULTS: The calibration curves of three ingredients were linear within the range of 3.666-73.32 mg?L -1(r=0.9998, baicalin), 0.3112-15.56 mg?L -1(r=0.9998, rhein), 1.221-50.04 mg?L -1(r=0.9999,berberine), respectively. The average recovery of baicalin is 102.3%(RSD=2.5%), berberine for 101.8%(RSD=1.8%), and rhein for 98.3%(RSD=2.9%). CONCLUSIONS: The method is rapid, sensitive and accurate.
