RESUMEN
Objective To explore the clinical effect of color Doppler ultrasound guided small incision in repairing penile fracture.Methods Sixteen cases of penile fracture single cavernosum rupture adopted the preoperative positioning by color Doppler ultrasound,hematoma removal and albuginea repair.The clinical effect was evaluated after operation.Results The albuginea rupture was smoothly found in 15 cases,1 case was converted to coronary sulcus annular degloving incision.The operation time was 20-60 min with a mean of 35 min;the postoperative hospital stay was 3.0-6.0 d with a mean of 4.8 d;the catheter removal was on postoperative 3-5 d,urination was unobstructed.Follow up lasted for 6-12 months,1 case appeared transient erectile dysfunction,the harden was touched during erection in 1 case,and other cases had no obvious complication occurrence.Conclusion The color Doppler ultrasound can locate the rupture of corpora cavernosa penis and albuginea.Selecting color Doppler ultrasound guided small incision in repairing penile fracture has small trauma and less complications,and can get satisfactory effect.
RESUMEN
<p><b>OBJECTIVE</b>To establish the double HPLC fingerprints of water-soluble composition and amino acids precolumn derivative reagent of 13 batches of Isatidis Radix micropower.</p><p><b>METHOD</b>The gradient elution was adopted with Hypersil BDS C18 column (4.6 mm x 250 mm, 5 microm). Water-soluble ingredients were detected with acetonitrile-0.1% phosphoric acid solution as mobile phase, flow rate 0.5 mL x min(-1), column temperature 20 degrees C, and the injection volume 10 microL. Amino acid ingredient were derived by PITC, and then were detected with mobile phase of 0.1 mol x L(-1) sodium acetate buffer solution (pH 6.5) - acetonitrile, flow rate 1.0 mL x min(-1), column temperature 30 degrees C, and the injection volume 5 microL. Both of the absorption wavelengths were 254 nm. Pharmacopoeia Commission "Chinese chromatographic fingerprint evaluation system (version 2.0)" was adopted to analyse, fingerprints of Isatidis Radix micropower were established, at the same time 4 main ingredients were recognized by the SPSS cluster analysis.</p><p><b>RESULT</b>Common mode of Fingerprint to water-soluble and amino acids ingredient of Isatidis Radix micropower was established, then adenosine, epigoitrin and 15 amino acids were identified as characteristic peaks. Cluster analysis showed that different kinds of the herbal Isatidis Radix micropower from different areas were different levels in the main ingredients.</p><p><b>CONCLUSION</b>Double fingerprints of Isatidis Radix micropower is established. Each peak is optimally separated in chromatogram, which provides a scientific basis for quality control of Isatidis Radix micropower.</p>
