ObjectiveTo investigate the effect of pravastatin on serum levels of interleukin-6(IL-6) and tu- mor necrosis faetor-α(TNF-α) in patients with acute coronary syndromes(ACS). Methods50 patients with ACSwere randomly divided into pravastatin group( n = 25) and routine therapy group( n = 25). Serum TNF-α and IL-6levels were measured before and four weeks after the two treatment options respectively. ResultsThe level of TNF- α and IL-6 were higher than routine therapy group before therapy(P < 0.01 ). The level of TNF-α and IL-6 weredecreased significantly after pravastatin therapy,and higher thancontrols(P < 0.05). The levels of TNF-α and IL-6changed only slightly after the routine therapy(P > 0.05). ConclusionThe level of TNF-α and IL-6 becominghigher in ACS patients may be related to the pathogenesis of ACS. Pravastatin can reduce serum level of TNF-α and IL-6 contributing to treatment of ACS.

Objective To explore the change of degrade of clonazepam in serum with single and repeated - dose administration in children with seizure, and find a reasonable method for using the clonazepam. Methods Children with seizures were divided into single - dose paradigam, repeated - dose paradigam, and decreased - dose paradigam. The concentration of CZP in serum was determined by high performance liquid chromatography( HPLC). Results The serum concentrations of clanazepain in single - dose paradigam were (101.9?12.1),(76.9 ? 5.8),(50.7?2.9),(30.9?5.4),(21.5?6.8)?g/L,the time point that the blood samples collected were 15,30,60,120 and 480 min. The serum concentrations in repeated - dose paradigam were (97. 2 ? 6. 1),(130.4? 13. 4), (99. 4 ? 9.8),(79.6?2.4)?g/L,in decreased-dose paradigam were( 101.1 ?13.1),(123.1 ?6. 6), (99.4 ?9. 8), (79. 3 ? 2. 2)?g/L,in these two groups,the time point were 15,45,60 and 120 min. Conclusion Repeated administration of CZP with decreased dose may increase its effectiveness in treatment without substantially increasing toxicity.

The β-Glucuronidase gene (sbGUS) cDNA firstly from Scutellari abaicalensis leaf was cloned by RT-PCR, with GenBank accession number KR364726. The full length cDNA of sbGUS was 1 584 bp with an open reading frame (ORF), encoding an unstable protein with 527 amino acids. The bioinformatic analysis showed that the sbGUS encoding protein had isoelectric point (pI) of 5.55 and a calculated molecular weight about 58.724 8 kDa, with a transmembrane regions and signal peptide, had conserved domains of glycoside hydrolase super family and unintegrated trans-glycosidase catalytic structure. In the secondary structure, the percentage of alpha helix, extended strand, β-extended and random coil were 25.62%, 28.84%, 13.28% and 32.26%, respectively. The homologous analysis indicated the nucleotide sequence 98.93% similarity and the amino acid sequence 98.29% similarity with S. baicalensis (BAA97804.1), in the nine positions were different. The expression level of sGUS was the highest in root based on a real-time PCR analysis, followed by flower and stem, and the lowest was in stem. The results provide a foundation for exploring the molecular function of sbGUS involved in baicalcin biosynthesis based on synthetic biology approach in S. baicalensis plants.
