ABSTRACT
Objective To investigate the changes of plasma microRNA-223(miR-223) and HMGB-1 in pediatric sepsis patients.Methods There were 49 children with sepsis enrolled in the study (sepsis group),severe sepsis group (n=25) and general group (n=24). Meanwhile, 50 healthy children (normal control group) were selected as control group. The expression levels of plasma miR-223and HMGB-1 (high mobility group box 1) were detected. The predictive values of miR-223and HMGB-1 in plasma of children with sepsis were evaluated by receiver operatingcharacteristic (ROC) curve.Results The plasma miR-223 and HMGB-1 expression levels in severe sepsis group and general group were up-regulated compared with those in the normal control group (F=63.02, 76.32,P<0.05). The area under ROC curve of miR-223,HMGB-1 predicting sepsis were 0.904 (95%CI 0.821-0.998), 0.748 (95%CI: 0.625-0.903). There was positive correlation between miR-223 and HMGB-1 (r=3.532, P<0.05). Conclusions The expression levels of plasma miR-223 in children with sepsis are signiifcantly up-regulated, which can be used as early diagnostic markers to relfect the severity of inlfammation in some degree.
ABSTRACT
Objective: To establish a method for the determination of cyasterone in Shenshixiao capsules. Methods: Using an HPLC method, the column was an Agilent C18 (250 mm × 4. 6 mm,5 μm) column, the mobile phase was methanol-water with gradient elution. The detection wavelength was 243nm, the flow rate was 1. 0 ml·min-1 ,and the temperature of column was room temperature. Results:The linear relationship of cyasterone was good within the concentration range of 0. 025-0. 247 μg(r=0. 999 6), the average recovery was 99. 4%, and RSD was 0. 76%. Conclusion:The method is rapid, simple and accurate, and can be used in the quality control of the preparation.
ABSTRACT
AIM: To establish the quality control standard for Compound Dingfengzhitong Capsule (Radix Notoginseng, Radix Saposhnikoviae, Radix Angelicae Dahuricae). METHODS: Radix Saposhnikoviae, Radix Angelicae Dahuricae in capsule were identified by TLC, and the content of ginsenoside R g1 was determined by HPLC. RESULTS: Radix Saposhnikoviae, Radix Angelicae Dahuricae could be identified by TLC. The Ginsenoside R g1 showed a good linear relationship at a range of 0.5286?g～26.43?g, r=0.9999(n=6) , the average recovery was 99.94%, and RSD was 1.34%( n =9). CONCLUSION: The method is accurate with the good reproducibility and can be used for the quality control of Compound Dingfengzhitong Capsules.
