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.

Objective To study the effects of ginkgo biloba extract(GBE)on c-reactive protein(CRP) and tumor necrosis factor-α(TNF-α)in serum and alveolar lavage fluid(BALF)from rats with chronic obstructive pulmonary disease(COPD). Methods 90 rats were randomly divided into groups A,B,C,D,E and F. There were 15 rats in each group. The rat model of COPD were established in groups B,C,D,E and F. Groups C and D were given intraperitoneal injections with GBE from day l to day l4 and day 29 to day 42. Groups E and F weregiven intraperitoneal injections with erythromycin from day l to day l4 and day 29 to day 42. After the end of experi-ment ,the contents of CRP and TNF-α in serum and BALF were detected in all groups. Results The contents of CRP and TNF-α in the serum and the BALF were markedly lower in groups C,D,E and F than in group B (P<0.05);and the contents of CRP in the serum and the BALF and TNF-αin the BALF were lower in groups C, E and F than in group D(P<0.05). Conclusions GBE can inhibit the airway and systemic inflammatory response in COPD rats. Early intervention is more effective.

Objective To explore whether 5 to -7-day of folic acid supplementation prior to pemetrexed therapy is needed. Methods We retrospectively evaluate the outcomes of non-small cell lung cancer patients received less than the advised folic acid premedication. Seventy patients with Ⅲ-Ⅳ NSCLC were randomly divided into two groups: patients who initiated vitamin supplementation on 7 days before the first dose of pemetrexed (group A) and patients who initiated vitamin supplementation on the day of the first dose of pemetrexed (group B). Results In group A and group B, CR 0 and 0, PR 10 and 8, the response rates of 28.6% and 22.9% were observed, respectively. There was no statistically significant differences between these two groups. No significant differences were observed in the incidence of hematologic and non-hematologic toxicities. Conclusions The initiation of pemetrexed-based chemotherapy does not need to accommodate a vitamin supplementation schedule.
