OBJECTIVE:To establish a gas chromatography(GC)method for determination of seven residual solvents in clofarabine.METHODS:The capillary column was AT-1301;the carrier gas was nitrogen gas and the detector was FID.By temperature programming was applied for the column temperature with an initial temperature of 40 ℃,which rose to 80 ℃ with an increase rate of 7 ℃?min-1,then rose to 200 ℃(kept at this temperature for 2 min)with the increase rate of 20 ℃?min-1.The injector temperature was 250 ℃ and the detector temperature was 280 ℃.The sample was injected directly for determination of residual levels of methanol,acetonitrile,dichlormethane,t-butyl alcohol,ethyl acetate,n-heptane and acetic acid in 3 batches of clofarabine.RESULTS:All the organic solvents were effectively separated and they showed good linearity within a concentration range(r=0.999 41～0.999 93)with average recovery rate ranged from 96.5% to 102.4%(RSDs of all were less than 4.0%).7 kinds of organic solvents in 3 batches of samples were all up to the standard specified in Chinese Pharmacopeia.CONCLUSION:The method is sensitive,accurate and reliable,and it is applicable for the determination of the residual solvents in clofarabine.

Objective To study the small intestinal absorption patterns of glimepiride in rats. Methods A rat model of small intestinal absorption in vivo was employed in this study. The small intestinal absorption rate of glimepiride was detected by high performance liquid chromatography. Results At the low and high concentrations of glimepiride, the average small intestinal absorption rates were 0.233 6 h -1 and 0.217 8 h -1 , respectively. Conclusion The small intestinal absorption pattern of glimepiride might be passive diffusion.

Objective To evaluate the effects of recombinant human bone morphogenetic-2-polylactide sustained release nanospheres (rhBMP-2-PLA-Ns) on cultured rabbit osteoblasts in vitro. Methods Rabbit osteoblasts were cultured in vitro, and rhBMP-2-PLA-Ns was added into the medium of the third generation of rabbit osteoblasts. The expression of the proliferating cell nuclear antigen (PCNA) was examined by immunofluoreacence staining, and the formation of tuberculums observed with alizarin red staining. Western blot was used to detect the effects of rhBMP-2-PLA-Ns on the expression of vascular endothelial growth factor (VEGF), which was compared with that in rhBMP-2 group and blank group. Results There was no significant difference in the number of osteoblasts with positive PCNA expression among three groups five days later. Ten days later, the number of osteoblasts with positive PCNA expression in rhBMP-2-PLA-Ns group was significantly higher than that in rhBMP-2 group and blank group, which indicated that rhBMP-2-PLA-Ns could enhance the expression of PCNA. Compared with rhBMP-2 group and blank group, rhBMP-2-PLA-Ns could significantly enhance the formation of tuberculums, with statistical difference (P<0.05). The expression of VEGF was detected in all three groups, and the level of the VEGF expression in rhBMP-2-PLA-Ns group was significantly higher than that in the other 2 groups (P<0.05). Conclusion The biological activity of rhBMP-2-PLA-Ns is superior than that of rhBMP2, and rhBMP-2-PLA-Ns can promote the proliferation, mineralization of osteoblasts and the secretion of VEGF, which has a better prospect in facilitating traumatic bone healing.

OBJECTIVE:To explore the present situation of scientific research of clinical pharmacists in domestic third-grade class A hospitals,and discuss its feasible research ideas. METHODS:Questionnaire was conducted for the scientific research situa-tion of clinical pharmacists who obtained the certification in domestic 63 third-grade class A hospitals,the questionnaire data was collected,and data was statistically analyzed by using IBM SPSS Statistics 22.0 software. RESULTS:Totally 315 questionnaires were sent out,282 were effectively received,with effective recovery of 89.52%. In terms of attitude to scientific research,propor-tion of the surveyed clinical pharmacists who thought it was quite necessary and necessary was more than 70%;except for academ-ic degree(P<0.05),the different gender,age and job title did not cause the differences in scientific research attitude(P>0.05). In terms of the present situation of scientific research,achievements of them were relatively simple,thinking the biggest difficulty was insufficient of experiment condition;there was significant difference in the numbers of authorized patents in recent 5 years by different gender (P<0.05),the numbers of applications for approved funds,authorized patents and paper published in recent 5 years by different academic degrees(P<0.05),as well as the numbers of applications for approved off-campus funds(title also re-lated to the number of hospital funds)and the numbers of paper published in domestic magazine in recent 5 years by different ages and job titles (P<0.05). In terms of direction of scientific research,most of surveyed clinical pharmacists thought they should strengthen communicate with physicians and look for the breakthrough point,they also thought the optimal one was clinical re-search;the direction selection was basically similar no matter the gender,academic degree,age and job title(P>0.05). In terms of ability enhancement,the surveyed pharmacists thought liter-ature review,evidence-based literature/experimental interpreta-tion and foreign language reading were the abilities most need to be enhanced;except for gender,academic degree,age andjob title showed similarity in enhancing the literature review,evidence-based literature/experimental interpretation ability (P>0.05),while there were significant differences in enhancing foreign language reading ability by different gender,academic degree, age and job title (P<0.05). CONCLUSIONS:Clinical pharmacists show certain differences in the attitude to scientific research, present situation and direction of scientific research,and ability enhancement because of different gender,academic degree,age and job title,but there are also common. In order to improve the competence of scientific research and promote the discipline devel-opment of clinical pharmacy,pharmacy administrator in hospital should improve the academic degree and job title on clinical phar-macists and provide necessary advanced scientific platform and pertinent training at the same time. Additionally,except for the ratio-nal drug use,evidence-based pharmacy and pharmacoeconomics,clinical pharmacists can find new breakthrough point from phar-maceutical care,drug treatment decisions,translational medicine and medicine large data.
