A novel method for quantification of astragaloside IV in Radix Astragli was developed by using online SPE liquid chromatography coupled with corona charged aerosol detection( CAD) . The sample solution
was loaded into Acclaim Polar AdvantageⅡC18(50 mm×4. 6 mm, 3 μm) which was selected as online SPE column. Then the cleaning process was done by using the Right one of dual gradient pumps with Methanol-water as mobile phase. Acclaim C18(150 mm×4. 6 mm, 5 μm) was selected as analytical column with acetonitrile-water as mobile phase at a flow rate of 1. 0 mL/min. The eluate containing the target from SPE column was transferred into the analytical column by heart-cutting mode. The temperature of nebulizer of corona CAD was set at 30 ℃ and the nitrogen pressure was 241. 3 kPa. The baseline separation of astragaloside IV from matrix components has been achieved. There was a good linear correlation in the range of 4 . 0-80 mg/L for astragaloside IV and the correlation coefficient was 0 . 9998 . The standard addition average recovery of astragaloside IV in Radix Astragli was 97 . 6%. It has been validated that astragaloside IV in Radix Astragli and its preparations can be quantified rapidly and accurately with this method.

Objective To establish an HPLC method for determination of pterodontic acid in Lingdancao Soft Capsula. Methods Agilent Zorbax XDB-C18 column (250 mm?4.6 mm, 5 ?m) was used. Acetonitrile-water (60∶40) was used as mobile phase, the detection wavelength was 210 nm, flow rate was 1.0 mL/min, and column temperature was at 25 ℃. Results The linear range of pterodontic acid was 12.91—129.1 ?g/mL (r=0.999 9), the average recovery rate of pterodontic acid was 99.7 %, RSD was 2.0%. Conclusion The method is simple, accurate, and reliable, and it can be used to the quality control of this preparation effectively as a quantitative method.

This paper presented the introduction of information technology to develop the hospital's one-card intelligent management system and its successful application. Thanks to the effective integration and linkage of hospital resources and information technology, such a system is built on the Internet of Things, platform + application, " Internet +" mindset. Thus the system can effectively achieve the service philosophy of strong security, high efficiency, and sustainable development, as well as more convenient access to medical treatment, more effective communication, and a new pattern of more comfortable medical and health services.
