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 observe the effect of Shenxian Yiganling Tablets ( SYT) , a Chinese herbal recipe with the actions of tonifying kidney and removing toxicity, combined with HBsAg gene-modified dendritic cells (DC/HBsAg) on immune response and hepatocyte damage of hepatitis B virus (HBV) transgenic mice. Methods HBV transgenic mice ( Tg mice) were immunized with injection of DC/HBsAg ( 100 μg every three weeks) through caudal vein, and then were given intragastric administration of SYT in the dosage of 12.8, 23.5, and 47.0 mg/d for four weeks. HBV Tg mice splenic T cell cytokines of interleukin 2 ( IL-2) and interferon gamma ( IFN-γ) levels as well as serum alanine aminotransferase ( ALT) and aspartate aminotransferase ( AST) conents were detected by enzyme-linked immunosorbent assay ( ELISA) . Lactate dehydrogenase ( LDH) release assay was used to detect the in-vitro cytotoxic activity of splenic HBsAg specific T lymphocytes. Serum HBsAg level of HBV Tg mice was detected by ELISA after immunization. Results Compared with DC/HBsAg administration alone, DC/HBsAg combined with SYT could significantly increase HBV Tg mice splenic T cells cytokines IL-2 and IFN-γ levels ( P<0.05 or P<0.01) , increase the cytotoxic activity of HBsAg-specific T lymphocytes ( P<0.05 or P<0.01), increase the inhibition rate of HBsAg expression (P<0.05 or P<0.01), and reduce hepatocyte damage. Conclusion SYT could enhance the immune response of Tg mice to DC/HBsAg immunization, and relieve the hepatic damage, which enable the HBV clearance process out of hepatic damage in the case of anti-HBV activity of IFN-γbeing unaffected.

Cerebral palsy (CP) is the most common activity limitition of children, their movement and posture impairments persist throughout whole life.In recent years, CP has been significantly increasing with the improved survival rate of newborns.This may lead to a great burden and costs to both the family and the society.A variety of risk factors have been proposed to be associated with CP.However, recent abroad researches indicate that genetic factors may predispose to CP of newborns and initial results of related researches infer that several susceptibility genes may contribute to CP's development, masqueraders have a great impact on CP's clinical symptoms.Now, the recent publications related to virulence genes and masqueraders of CP are reviewed.
