Objective: Farnesyl pyrophosphate synthase (FPS) gene of Fritillaria thunbergii was cloned and the correlation between the expression content of gene and alkaloid accumulation was analyzed to explore the role of FPS gene in the regulation of alkaloid synthesis and metabolism. Methods: In this study, the new bulbs and different tissues of Fritillaria thunbergii varieties "Narrow leaf" "Broad leaf" and "New Meiyuan" were used to clone the full-length sequence of FPS gene via RACE technology. RT-qPCR and HPLC-ELSD technology was used to determine the expression of FPS in 10 different developmental stages and the content of alkaloid (Peimine and Verticinone), respectively. Finally, the correlation was analyzed. Results: The full-length cDNA sequence of FPS gene was 1 629 bp. Open Reading Frame (ORF) was 1 056 bp and encoded 351 amino acids. Among them, the tissue specific expression trends of FPS gene were same, flowers had the highest expression level, followed by the new bulb. The results of correlation analysis showed thatthe content Peimine and Verticinone had significant positive correlation with the expression level of FPS gene in "Broad leaf" and "New Meiyuan" (The correlation coefficients were 0.289 and 0.613, 0.427 and 0.622, respectively);FPS gene expression and alkaloid content in different tissues had a positive correlation (The correlation coefficients were 0.057 and 0.476, 0.085 and 0.495, 0.375 and 0.432, respectively). Conclusion: The full-length sequence of FPS gene was successfully cloned in this study. The FPS gene involved in the regulation of alkaloid synthesis and metabolism.

OBJECTIVETo systematically review the effectiveness of bone substitute augmentation combined with internal fixation versus internal fixation alone in treating proximal femoral fractures in the elderly.

METHODSSubject term and keywords were searched from Pubmed, Cochrane databases and CNKI from database foundation to August 2015. Randomized controlled studies and qusi-randomized controlled studies on bone substitutes augmentation combined with internal fixation versus internal fixation alone for the treatment of proximal femoral fractures in the elderly were chosen. Postoperative re-displacement, re-operation rate, complications (infection and bone ununion), functional outcome, quality of life scores and muscle strength were seen as outcome indicators. Enumeration data were statistical analyzed by risk difference and 95% confidence interval. Measurement data were analyzed by standardized mean difference and 95% confidence interval. If the same measurement data were evaluated by different standards in different studies, standardized mean differences and 95% confidence interval were used. The methods of statistical analysis were used by Cochrane databases.

RESULTSEleven RCTs (677 patients) were included. Meta-analysis results indicated that bone substitutes augmentation combined with internal fixation occurred fewer re-displacement [SMD = -0.75, 95% CI (-1.03, -0.47)] and obtained better function [SMD = 0.40, 95% CI (0.20, 0.59)]. While there were no significant differences in reoperation rate [RD = 0.02, 95% CI (-0.05, -0.09)], pain at 1 week after operation [MD = -1.79, 95% CI (-13.55, -9.96)], pain ranged from 6 to 8 weeks [MD = -7.24, 95% CI (-20.07, -5.59)], postoperative pain at 12 weeks [MD = -0.32, 95% CI (-4.9, -3.55)], muscle strength [MD = 1.25, 95% CI (-6.98, -9.48)], bone ununion [RD = 0.02, 95% CI (-0.01, -0.05)] and postoperative complications [MD = 0.01, 95% CI (-0.03, -0.04)].

CONCLUSIONCompared with single internal fixation, bone substitutes augmentation combined with internal fixation for the treatment of proximal femoral fractures in the elderly less occur re-displacement and could obtain better functional recovery.

Objective To investigate the relationship between CYP19 gene polymorphism and Alzheimer disease. Methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to analyze the allele frequency distribution at the Mfe Ⅰ site of CYP19 gene in 102 patients with Alzheimer disease and 121 healthy control subjects. Results The frequencies of CYP19 ml and m2 alleles showed significant differences between the patient group and the control group (66.2% vs 81.0% and 33.8% vs 19.0%, respectively, X2=12.696, P<0.05). In patients with Alzheimer disease, the frequencies ofm1/m1, m1/m2, m2/m2 genotypes of CYP19 gene were 44.1%, 44.1%, and 11.8%, respectively, showing significant differences from the frequencies in the control subjects (65.3%, 31.4%, and 3.3%, respectively, X2=12.384, P<0.05). Conclusion CYP19 gene polymorphism at the Mfe Ⅰ site is associated with the genetic susceptibility to Alzheimer disease.

To investigate the modulation on the P-glycoprotein in the jejunum by combined use of Glycyrrhiza inflata and Kansui with ussing chamber and rt-pcr, Rhodamine 123 (R123), a P-gp substrate and fluorescein sodium (CF), a model drug of non-P-gp substrate transported by a passive diffusion were taken as investigational drugs. Because these two drugs can be easily assayed and widely used in various research fields. The permeability of R123 or CF via Wistar rat jejunum membranes was evaluated by in vitro ussing chamber after oral administration of four different decoctions of Glycyrrhiza inflata and Kansui for 1 week. And the concentration of R123 or CF was determined by the fluorospectrophotometry in the receiving solution. Meanwhile the expression of mdr1a in P-glycoprotein was detected by real-time fluorescent quantitative PCR. After oral administration of combined decoction of the single drug, the absorptive directed permeability of R123 increased significantly (P < 0.01). On the other hand, Kansui and combine decoction of the two drugs also decrease the permeability of secretory directed transport (P < 0.05). No action of Glycyrrhiza inflata was found on the secretory transport of R123 [Papp = (2.56 +/- 0.38) x 10(-5), cm x s(-1)] across the jejunum tissues, while Papp of control group was found [Papp = (2.35 +/- 0.27) x 10(-5), cm x s(-1)]. After oral administration of Kansui decoction for 1 week and 2 weeks, the levels of mdr1a expression in Wistar rats were lower than that of the control group, but there were no significant difference in the results. Meanwhile, Glycyrrhiza inflata had no effect on transport of CF across the jejunum tissues, though the other three groups could decrease the permeability of CF, as compared with control group. Kansui may slightly inhibit P-glycoprotein function in the intestinal membrane. For another, some compositions in Kansui inhibit P-glycoprotein function, and some others strengthen the tight junction between cells in the intestinal membrane to decrease permeability of CF. As the inhibitory action to P-glycoprotein was enhanced by combination of Glycyrrhiza inflata and Kansui, based on the results, it may be one of the mechanisms of creating toxicity once co-administration of Glycyrrhiza inflata and Kansui.
