ABSTRACT
Objective To investigate the mechanism and clinical characteristics of rapid spontaneous resolution of acute subdural hematoma in children. Methods The clinical data of 9 children with rapid spontaneous resolution of acute subdural hematoma were retrospective analyzed. Results Subdural hematoma of three cases were completely dissolved within 8 h, while those of the other 6 cases were significantly reduced which were completely dissolved in 48-72 h. Conclusions Rapid spontaneous resolution of acute subdural hematoma in children is rare in clinical practice. The redistribution and dilution of hematoma and the anatomical characteristics of the children patient determine the possibility of hematoma dissipation. The conservative treatment can get a good prognosis.
ABSTRACT
Objective To establish the fingerprint for evaluation of Zhenhuang Capsules (Scutellaria Extract, Notoginseng Radix et Rhizoma, et al). Methods The fingerprint was established by HPLC with photodiode array detector (PADA). The mobile phase was methanol-0.1%phosphoric acid (gradient elution), column temperature was at 35 ℃, flow rate was 1.0 mL/min, and detection wavelength was at 280 nm. Results There were 15 common peaks appeared in the HPLC-PADA fingerprint which was defined by Similarity Evaluation System for Chromatographic Fingerprint of TCM (Version 2004A) published by Committee of Pharmacopoeia of China. The similarity of 11 batches examples with the control was more than 0.99. Conclusion The method is simple, accurate and sensitive, with good reproducibility. It is suitable for quality evaluation of Zhenhuang Capsules.
ABSTRACT
Objective To set up a method for determining Specnuezhenide in Shengxinfa Capsules. Methods With HPLC method, Agilent TC-C18 column (4.6 mm×250 mm, 5 μm) was used. Mobile phase was methanol-water (35∶65), the flow rate was 1.0 mL/min, and the detecting wavelength was at 224 nm. Results The linearity was in the range of 0.15-0.90 μg. The average recovery was 100.35%, and RSD was 1.43%. Conclusion The method is accurate, reliable, and can be used for the determination of Specnuezhenide in Shengxinfa Capsules for its quality control.
ABSTRACT
Objective To set up a method for determining the quercetin in Pyrola calliatha H.Andres.Method HPLC method was carried on Agilent Eclipse XDB-C18 column(4.6 mm?150 mm,5 ?m) with mobile phase of methanol-0.1% phosphoric acid(50:50),and the detecting wavelength was at 370 nm.Result The standard curve was linear within the range of 0.092～0.46 ?g.The average recovery rate was 99.24% and RSD was 0.70%.Conclusion The method is simple,accurate,highly sensitive and reproducible.It can be used for the quality determination of quercetin in Pyrola calliatha H.Andres.
