Objective To investigate the endovascular treatment of peripheral vascular anomaly in children and its efficacy.Methods Eighty-three children with peripheral vascular anomaly were treated via endovascular means. Before and during the endovascular operation,all the cases were diagnosed as follows: arteriovenous fistula in 23 cases, cirsoid angioma 32 and cavernous hemangioma 28. The endovascular approaches included:①transcatheter embolization using coils or gelfoam sponge;② transcatheter embolization combined with local cirrhosis agents treatment.Results Immediate angiography after embolization showed all the arteriovenous fistulas and hemangiomas were efficiently occluded and the clinical presentation and symptoms improved greatly. Follow-up one to three years after operation demonstrated 100% of efficacy and 68.7% curative rate with no complications. Conclusions Endovascular approach for peripheral vascular anomaly in children is a micro-invasive, safe and effective way.

OBJECTIVETo study the water soluble constituents from Amomum villosum.

METHODThe constituents were separated and purified with chromatographic methods, identified by NMR, MS, UV and IR.

RESULTTwo quercetin glycosides: quercitrin (quercetin-3-O-alpha-L-rhamnoside I) and isoquercitrin (quercetin-3-O-beta-D-glucoside II) were isolated and identified.

CONCLUSIONI and II were isolated for the first time from A. villosum.

The aim of this study is to assess the antibacterial and anti-biofilm properties of the lipid extract from Mantidis ootheca against the gentamycin resistant Pseudomonas aeruginosa. The chemical composition of the lipid extract and its relative proportion were determined using the technique of gas chromatography coupled with mass spectrometry (GC-MS). Antibacterial susceptibility tests were performed using a disc diffusion assay and the minimum inhibition concentration (MIC) was determined by way of the agar dilution method. The anti-biofilm test was carried out with crystal violet staining and scanning electron microscopy (SEM). There were 16 compounds detected, and the most abundant components were sesquiterpenoids, monoterpenes, and trace aromatic compounds. The MIC for P. aeruginosa was 4 mg/ml and the eradication effect on preformed biofilms was established and compared with a ciprofloxacin control. The results of our study indicated that a lipid extract from M. ootheca could be used as a topical and antibacterial agent with anti-biofilm activity in the future.
