The research was carried out to establish HPLC fingerprints of Tibetan medicinal herb "Songdi" (Saxifraga umbellulata var. pectinata), and to provide reference for identification an quality control of it. It was performed on an Amethyst-C18-P (4.6 mm x 250 mm, 5 microm) column with the mobile phase of methanol-0.4% formic acid in a linear gradient mode at a flow rate of 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 254 nm. The software for chromatographic fingerprint was applied to analyse the pattern analysis, the common peaks and similarity. Cluster analysis was done based on the common peaks data of 33 samples from different plant species and sources by SPSS software. Ten common chromatographic peaks were identified by fingerprint, showing a low similarity in constituent and variety. Flavonoids and saponins were the principal components. The number and area of peaks were affected by the collection sources and method. The high similarity are showed by the samples derived from the same area with high accuracy and high purity. The method is so simple, exclusive, stable and high repeatable that it can provide reference for identification and quality assessment of "Songdi" (S. umbellulata var. pectinata).

Objective To develop a Chinese military psychosomatic health scale(CMPHS) and examine its reliability and validity. Methods Based upon the previous researches, the Scale was compiled according to open-ended inventory survey. The data was collected from 1050 subjects chosen by random cluster sampling. 60 of them were tested with the CPSHS at the same time, while 61 of them were retested with the CMPHS after two weeks. The reliability and validity were examined by exploratory factor analysis ( EFA) and correlation analysis. Results According to the factor analysis results, 11 factors were extracted, namely espiratory apparatus, alimentary system,skeletal and musculature,integument,regeneration and endocrine,nervous system, anxiety, depression, psy-choticism and family history. There were 91 items in the formal scale when one lie subscale was added. The correlation between subscales were 0. 103 ~ 0. 778 (P < 0. 01) , the correlation between subscales and total scale were 0.600 ~0.859(P<0.01). The test-retest correlation coefficients of total scale and subscales were 0.427 ~0.901 (P < 0.01); the Cronbach (α) coefficients were 0. 643 ~ 0. 935 (P < 0. 01) ; and the split-half correlation coefficients were 0. 349 ~ 0. 855 (P < 0. 01 ). The correlation coefficients were 0. 425 ~ 0. 979 (P < 0. 05 or 0. 01 ). Conclusion The Chinese military psychosomatic health scale has acceptable psychometrics properties on reliability and validity.
