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.

OBJECTIVE:To systematically review the efficacy and safety of salmeterol and fluticasone propionate aerosol in the treatment of AECOPD and provide evidence-based reference for the clinical treatment. METHODS:CJFD,Wanfang database, VIP,CBM,Cochrane Library,PubMed and EMBase were retrieved to collect the randomized controlled trial(RCT)of efficacy and safety of salmeterol and fluticasone propionate aerosol in the treatment of AECOPD. After information collection and quality evalua-tion,Meta-analysis was performed by using Rev Man 5.1 software. RESULTS:There were totally 17 RCTs,including 2 872 pa-tients. Results of Meta-analysis showed FEV1[SMD=0.47,95%CI(0.41,0.53),P<0.001],FEV1/FVC [SMD=1.08,95%CI(0.76, 1.39),P<0.001],FEV1 percentage of predicted value[SMD=0.83,95%CI(0.60,1.06),P<0.001] and incidence of adverse reac-tions [RR=1.38,95%CI(1.02,1.87),P=0.03] in test group were significantly higher than control group,with significant differenc-es. CONCLUSIONS:Salmeterol and fluticasone propionate aerosol has good efficacy in the treatment of AECOPD,can better im-prove patients’lung function and the safety needs to be improved. Due to the limit of research methodology,it remains to be fur-ther verified by large-sample and high-quality RCT.

OBJECTIVETo investigate the effect of modified bone morphogenetic protein-2 polylactic acid nanospheres (BMP-2-PLA-Ns) sustained-release system on rabbit mandibular defect repair.

METHODSThe polylactic acid s nanospheres (PLA-Ns) and BMP-2-PLA-Ns were prepared by ultrasonic emulsification after graft polymerization. Forty-five rabbits were randomly divided into 3 groups: Blank group, PLA-Ns gel group(control group), and BMP-2-PLA-Ns gel group (experimental group). The rabbit mandibular defect models were established. The defect area of control group was implanted with PLA-Ns gel, meanwhile, the experimental group was implanted with BMP-2-PLA-Ns gel, the blank group experienced no special handling. Rabbits were killed in 1, 2, 4 weeks after operation and the iconography, hematine eosin(HE) staining and PCNA immunohistochemistry were used to detect the reparative effect on rabbit mandible defects.

RESULTSImage observation showed that bone defect repair in the experimental group was well and the shadow was not obvious. Better repair effect was seen compared with the control group and blank group. HE staining showed that the experimental group and the control group had a large number of neovascularization and secondary callus formation, callus in experimental group was obviously higher than that of control group and blank group. Immunohistochemical observation showed that the experimental group's PCNA positive chondrocytes were more than those in the control group and the blank group in the first 2 weeks; all groups of PCNA positive cells were rare in the fourth week, PCNA positive expression rate of the fourth week was lower than that of the first 2 weeks.

CONCLUSIONThe modified BMP-2-PLA-Ns sustained-release system promotes mandibular defect repair obviously.

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.
