The contents of schisandrin, schizandrin A, B and C were determined by HPLC, and the effects of the climate factors and altitude on lignin contents were analyzed in order to select the optimal cultivation area of S. chinensis. The lignin contents were analyzed by HPLC using a ZORBAX SB-C18 column (4.6 mm x 250 mm, 5 microm). The column temperature and detection wave length were set at 35 degrees C and 254 nm, respectively. Methanol-water was used as the mobile phase in gradient elution mode and the flow-rate was 1.0 mL min(-1). The method had a good repeatability, stability and accuracy. The correlation of climate factors and lignins contents was analyzed by SPSS software. The results showed that the schizandrin A content in S. chinensis fruits were higher than 0.4% in Ji'an, Liuhe, Antu and Fusong in Jilin province, which met the quality requirement. It had significant linear negative correlation relationship between schisandrin, schizandrin A, B and altitude, the contents decreased with the increase of altitude. The significant negative linear fitting coefficient was 0.844 1 between schisandrin and altitude; but it had not significant correlation between schizandrin C and altitude. A significant positive correlation of climate factors and the contents of S. chinensis lignins were mainly the temperature factors (the average annual temperature, the highest temperature in July, the average temperature in July, the highest temperature in January, the average temperature in January) and precipitation factor (average annual precipitation), which reveals that higher temperature and precipitation were helpful to the formation and accumulation of lignins of S. chinensis. So the cultivation area of S. chinensis should be in the low elevations region with warm and rainy climate.

Medicinal values and their chemical bases of Paris (Trilliaceae) are reviewed. Paris plants include 40 species and varieties. Among them, 18 ones are medicinal plants with similarity in traditional uses. Fourteen species have been studied phytochemically, which led to isolation of 207 compounds including 121 steroidal saponins. These saponins are major active constituents from Paris plants, which can explain the traditional uses of the plants to treat cancer, malignant boil, bleeding, gastritis, and so on. The similarity in medicinal uses and chemical constituents of Paris plants implies the possibility of resource substitution among these species. It is worth to further investigate Paris plants in chemical constituents, pharmacological activity, biological property, and toxicology.

Objective To investigate SLC25A13gene mutation in neonatal intrahepatic cholestasis caused by citrin defi-ciency (NICCD). Method A total of 17 children with NICCD were collected. PCR-RFLP method was used to analyze the most common eight mutations of SLC25A13 gene in Chinese populations and results were analyzed together with routine laboratory examinations. Results In the 17 NICCD patients, there were six cases of homozygous mutation, three cases of compound heterozy-gous mutation and eight cases of single heterozygous mutation in SLC25A13 gene. Three kinds of mutations detected were 851del4 (73.1%), 1638ins23 (11.5%) and IVS6+5G>A (15.4%). The seventeen cases showed classical NICCD symptoms of low birth weight, pathological jaundice. And laboratory data suggested liver dysfunction, hyperbilirubinemia, hyperbileacidemia, hy-poproteinemia, hypoglycemia, coagulation disorders, hyperlactacidemia and hyperammonemia. Conclusions 851del4, 1638ins23 and IVS6+5G>A are hot spots of SLC25A13 gene mutation in Chinese populations. PCR-RFLP is a rapid, convenient and reliable technology for NICCD molecular diagnosis.

To investigate the distribution of the genes of two major metallo-beta-lactamases (MBL; i.e., IMP and VIM) and class 1 integrons (intI) in the clinical imipenem-resistant Pseudomonas aeruginosa, a total of 65 isolates, from a university hospital in Sichuan between December 2004 and April 2005 were screened for MBL genes by PCR using primers specific for bla ( IMP-1 ), bla ( VIM ) and bla ( VIM-2 ) genes. The MBL-positive isolates were further assessed for class 1 integrons by PCR using specific primers. The nucleotide sequences of several PCR products were also determined. The results revealed that the bla ( VIM ) gene was found in 81.5% (53/65) of all isolates, bla ( VIM-2 ) gene was found in only 1 isolate and the intI gene was observed in 45.3% (24/53) of bla ( VIM )-positive isolates. One isolate carried simultaneously both bla ( IMP-1 ) and intI genes, and to the best of our knowledge this is the first report of such isolate in southwest China. These observations highlight that the genes for VIM beta-lactamase and class 1 integrons were predominantly present among the imipenem-resistant P. aeruginosa tested, confirming the current widespread threat of imipenem-resistant, integron-borne P. aeruginosa.
