OBJECTIVE: To strengthen monitoring on the clinical use of antibacterials so as to promote rational drug use. METHODS: Clinical pharmacists worked on the rational use of antibacterials, offered consultation guidance and monitoring to participate the affairs about hospital infection control. RESULTS & CONCLUSIONS: Clinical pharmacists' participation in hospital infection control by strengthening the monitoring of the rational clinical use of antibacterials, participating in clinical consultance of critical infective patients, careful evaluating prescriptions and medical histories in respect of the rationality of drug use can help strengthen the control on the clinical use of antibacterials.

Objective:To analyze the intellectual property risk of international cooperative scientific research involving human genetic resources, explore possible risk control measures regarding to intellectual property.Methods:By means of literature review, this paper analyzes the special attributes and strategic position of human genetic resources, reviews the policies and systems involving human genetic resources in international cooperative scientific research, identifies the intellectual property risk points, and puts forward suggestions on risk management and control from the perspective of intellectual property protection.Results:The management of human genetic resources in China is evolving quickly. However, there is still a lack of practical guidelines on intellectual property protection and development, more substantial engagement and contribution of Chinese investigators in the international collaborative research should be promoted, and the perception and awareness of the significance of human genetic resources should be enhanced.Conclusions:In the international cooperative scientific research involving human genetic resources, we should clarify the operating rules at the level of intellectual property protection, improve the substantive participation of Chinese investigators, enhance the strategic awareness and risk awareness of human genetic resources, and provide support at the level of executive management institutions.

Objective:To analyze the disadvantages of " paper-centric" in science and technology evaluation, explore how to establish a new evaluation model of scientific and technological innovation in academic universities in China on the premise of breaking the " paper-centric" orientation.Methods:Analyze problems and disadvantages of the " paper-centric" orientation in the evaluation of science and technology at academic universities in China, take account into the in-depth interpretation of key policies of breaking away from " paper-centric" in recent years, and finally make proposal for the establishment of evaluation system and mode of scientific and technological innovation in the future.Results:There are many pitfalls in the " paper-centric" orientation in the evaluation of science and technology in academic universities in China, thus, it is urgent to establish a new evaluation mode of scientific and technological innovation.Conclusions:Based on the current domestic and international context, academic universities in China should deploy the strategy of scientific and technological innovation in advance, break the " paper-centric" orientation, and establish a new evaluation system and mode of science and technology that proactively match the national strategy and the development requirement.

Objective To investigate the effect of spleen on hepatic macrophages mediated activation of hepatic stellate cells(HSCs)in mice with liver fibrosis.Methods Eighteen male C57BL/6 mice were randomly divided into three groups.Mice in Group A and Group B were injected intraperitoneally with CCl4 to establish liver fibrosis mouse model,while those in Group C were injected with corn oil as normal control.Four weeks later,mice with liver fibrosis received splenectomy(Spx)or sham operation(Sham),respectively.After continuous injection for 2 weeks,liver homogenates(L-Homo)were prepared and liver cells were isolated from the three groups.Expressions of IL-1β,IL-13,TGF-β,TNF-α,PDGF-β and VEGF in the liver homogenates of the three groups were detected by Luminex multifactor analysis.The expressions of these cytokines in liver macrophages(L-Mψ)and other non-parenchymal cells of Sham and Spx mice were analyzed by Real-time quantitative PCR(RT-qPCR)and flow cytometry.Macrophage cell line RAW264.7 or bone marrow-derived macrophages(BMDMs)were treated with liver homogenates from the Sham and Spx groups.Then the differently treated RAW264.7 cells were analyzed for mRNA expressions of cytokines and glutamine metabolism-related molecules by RT-qPCR,or transwell co-cultured with hepatic stellate cell line JS1.After co-culture,the survival and extracellular matrix expression of JS1 cells were analyzed.For comparison,Student's t test(between two groups)or one-way analysis of variance(among multiple groups)were used.Results Compared with normal control group,the concentrations of IL-1β,IL-13,TGF-β and TNF-α in the L-Homo of model group were significantly increased and showed higher levels in Sham group than in Spx group.Moreover,the hepatic macrophages were indicated as the major source of these cytokines.Consistently,macrophages treated with liver homogenate of Sham mice had increased expressions of IL-1β,TGF-β and TNF-α and glutaminase(GLS).After co-culture with macrophages treated with liver homogenate of Sham group rather than Spx group,JS1 expressed higher expressions of α-SMA and collagens.Conclusion The spleen is involved in regulating the secretion of cytokines by hepatic macrophages and enhancing their ability to activate hepatic stellate cells.
