Objective　To research the anterior corneal stromal puncture therapeutic effect for bullous keratopathy.Methods　The causes of the bullous keratopathy of the 11 cases were analysed and the bullous keratopathy was cured by the anterior stromal puncture methods.Results　Eleven cases were followed up for three months.The symptoms were relieved in all cases. The corneal bullous disappeared.Conclusion　The cases of the bullous keratopathy caused by mechanical or physical factors can be cured more effectively by using anterior corneal stromal puncture therapeutics.

OBJECTIVETo develop a HPLC method for simultaneous determination of caffeic acid, rosmarinic acid, oleanolic acid and ursolic acid in Spica Prunellae.

METHODAfter ultrasonic extraction with 75% ethanol solution containing 1% formic acid, the ethanol-extract of Spica Prunellae was analyzed on an Elite SinoChrom ODS-AP column using gradient elution of 0.01% phosphoric acid (A) and acetonitrile (B) at a flow rate of 0.9-1.0 mL x min(-1). A wavelength switch program was used for detection at 330 nm (0-33 min) and 203 nm (33-40 min). The column temperature was set at 20 degrees C and injection volume was 50 microL.

RESULTThe calibration curves of all analytes were linear. The average recoveries were 93.7%-105.2% with RSDs not more than 4.5%. The contents of caffeic acid, rosmarinic acid, ursolic acid and oleanolic acid in Spica Prunellae were 0.0401-0.0968, 0.99-2.57, 0.243-0.556, 4.06-8.13 mg x g(-1), respectively.

CONCLUSIONThe described method is sensitive, convenient and accurate, and is suitable for the simultaneous determination of caffeic acid, rosmarinic acid, oleanolic acid and ursolic acid in Spica Prunellae.
