3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) is the first rate-limiting enzyme for sesquiterpene synthesis in the mevalonate (MVA) pathway. The specific primers were designed according to the transcript sequence of AsHMGR2 from the Aquilaria sinensis (Lour.) Gilg transcriptome database. The full-length cDNA of AsHMGR2 was cloned by RT-PCR and rapid amplification of cDNA ends (RACE) technology, and was analyzed at bioinformatics levels; AsHMGR2 expression profiles in different tissues and in responds to different treatments were analyzed by real-time PCR. The length of AsHMGR2 Open Reading Frame (ORF) was 1 749 bp, encoding 582 amino acids. The GenBank accession number is KC140287. Tissue expression analysis indicated that AsHMGR2 was mainly expressed in root and shoot tips, followed by stem, and was lowest in leaves. Inducible-experiments showed that the genes were induced by mechanical wound as well as chemical liquid induction, and reached the highest expression level at 6 h and 8 h, separately. The full-length cDNA of AsHMGR2 and its expression patterns will provide a foundation for further research on its function in agarwood sesquiterpene biosynthesis.

Objective:To study the inhibition of astragaloside on the proliferation of human keloid fibroblasts. Methods: Com-pared with that of normal skin, the expression of transforming growth factor-β( TGF-β) and its transduction factors Smad in the human keloid fibroblasts was detected. The optimal concentration was screened by MTT after HFF-1 human skin fibroblast was infected with astragaloside at different concentrations. The mRNA expression of Smad2, Smad3, Smad4 and Smad7 in the fibroblasts was studied by using real-time. The protein expression of TGF-βRⅡ, Smad2, Smad3, Smad4 and Smad7 in the fibroblasts was detected by using Western blot. Results: Compared with that of normal skin tissue, the expression of Smad protein was significantly increased ( P <0. 05) in the human keloid fibroblasts, and there was no significant difference in the TGF-βRⅡ expression (P>0. 05). The optimal concentration of astragaloside was 0. 5μg·ml-1 . The expression level of Smad2 protein in the two groups was significantly increased, and the level of Smad3 expression was significantly decreased (P<0. 05). Conclusion:Astragaloside can inhibit the formation of fi-broblast possibly through Smad2 over-expression and Smad3 inhibition in the TGF-β/Smad signal transduction pathway.

AIM: To evaluate the influences of triptolide on serum cytokines, symptoms and pulmonary function in patients with steroid - resistant asthma, so as to investigate if there is therapeutic effect of triptolide on these patients. METHODS: Sixteen patients with steroid - resistant asthma were randomly divided into two groups (A and B, n =8 for each group). All of the patients took procaterol (50 - 100 μg/d) and theophylline (400 mg/d) orally as baseline treatment. Additionally, triptolide was prescribed for group A (33 μg, orally, three times per day for 4 weeks). Asthmatic symptom score calculation, serum cytokines ( interferon - γ, IFN - γ; interleukin - 4, IL - 4; and interleukin - 5, IL - 5)determination and pulmonary function test (FVC%, FEV1%, PEF%, V50% and V25% ) were undertaken before and at the end of the study. RESULTS: At baseline, no significant difference was found between group A and group B with respect to the above mentioned indices. Following the administration of triptolide, group A had significantly increased serum IFN -γlevel, FVC%, FEV1%, PEF%, V50% and V25%, and significantly decreased asthmatic symptom score and serum IL-4, IL-5 levels (P<0.01 compared with baseline in the same group, and P<0.05 compared with group B at the end of the study). Compared with baseline, no significant change was observed for group B regarding all the indices at the end of the study. CONCLUSION: Triptolide in combination with procaterol and theophylline may be a novel and effective strategy for the treatment of steroid - resistant asthma.
