Objective:To suggest approaches for the establishment of Chinese standards for defining rare disea-ses and advance corresponding Chinese legislation. Methods:By comparing the standards for defining rare diseases in Europe, the United States, and other countries and studying key influencing factors of standards, this paper proposes suggestions for the establishment of proper Chinese standards for defining rare. Results and Conclusion:Social and e-conomic development levels, medical development levels and social security levels influence the establishment of standards. It is recommended that the national conditions should be taken into consideration and the number of pa-tients, severity of the diseases and economic indicators of orphan drugs be used to define rare diseases in China.

Objective: To provide policy recommendations for improving price negotiation system of patented drugs in China. Methods: This paper comparatively analyzes the commonalities and characteristics between Korea’ and Germany’s price negotiation models for patented drugs from three aspects of their goals, procedures and effects. Results:The key objective of both Korea’ and Germany’s price negotiation systems for patented drugs is to efficiently improve the utilization of national health insurance services, and responsibilities are properly assigned among differ-ent institutions to ensure the equity and efficiency of negotiations. However, due to the differences in national cir-cumstances, there is a big difference in the selection of technical assessment criteria. Conclusion: This paper sug-gests China to strengthen the convergence between price negotiations for patented drugs and medical insurance reim-bursement policy, to establish a technical assessment system with the innovation extent for patented drugs as its core, and to develop scientific and rational negotiation procedures and division of responsibilities as well.

OBJECTIVE:To evaluate the application effects of PDCA cycle management in the outpatient prescription intervention.METHODS:A total of outpatient prescriptions (pre-intervention group) during Jan.-Dec.2014 and 918 659 (intervention group) were selected during Jan.-Dec.2015 were selected from a hospital.Irrational 9utpatient prescriptions were analyzed before and after the application of PDCA cycle management,and the improvement of main indexes were compared such as unsuitable usage and dosage,incomplete clinical diagnosis writing,no physicians' signature on the prescription or inconsistent with sample.RE SULTS:Before intervention,there were 2 347 irrational prescriptions,including 1 401 nonstandard prescriptions,849 unsuitable prescriptions and 97 abnormal prescriptions.After intervention,there were 1 161 irrational prescriptions,including 695 nonstandard prescriptions,425 unsuitable prescription and 41 abnormal prescriptions,decreasing 50.53％,50.39％ 49.94％ and 57.73％,respectively.The proportion of unsuitable usage and dosage,incomplete clinical diagnosis writing,no physicians' signature on the prescription or inconsistent with sample,nonstandard prescription paper,unsuitable indications,no signature and date for prescription revision or no reason and new signature for overdose use,outpatient prescriptions more than 7 d common dose or emergency prescriptions more than 3 d common dose without special situation in total amount of outpatient prescriptions decreased from 0.72‰,0.57‰,0.45‰,0.27‰,0.20‰,0.19‰ and 0.15‰ before intervention to 0.32‰,0.25‰,0.19‰,0.11‰,0.09‰,0.08‰ and 0.07‰ after intervention.CONCLUSIONS:PDCA cycle management significantly improves the quality of outpatient prescriptions.There still are irrational outpatient prescriptions in this hospital,and it is to be intervened continuously.

Objective To investigate the effect of different function of sympathetic nerve on the pain of peripheral nerve chronic compression. Methods Forty-eight male Sprague-Dawley rats were made into lower trunk chronic compression models and divided into 6 groups (A1,B1,C1,A2,B2,C2) with 8 rats per group. The C8T1 dorsal root ganglions of the compressed sides of group A1 (control group), B1 (sympathetic block group)and C1 (de-sympathetic group) were harvested 3 months after compression surgery. The compressed lower trunks of group A2 (control group), B2(sympathetic block group)and C2(de-sympathetic group)were decompressed 3 months after compression surgery and bred for another month and then the C8T1 dorsal root ganglions of the compressed sides were harvested. The levels of substance P mRNA in the C8T1 dorsal root ganglions were tested with RT-PCR technique. Results the mean relative levels of substance P mRNA of group A1, B1 and C1 were (3.620 ± 0.830) × 10-2, (2.945 ± 0.724) × 10-2, (2.239 ± 0.734) × 10-2, respectively, with a significant difference (P = 0.006) and those of group A2, B2 and C2 were (3.163 ± 1.026) × 10-2, (2.355 ± 0.680) × 10-2,(1.487 ± 0.802) × 10-2, the difference among which was statistically significant (P = 0.003). Conclusion The pain of peripheral nerve chronic compression is affected by sympathetic function. The more lower the sympathetic function is, the more light the pain is. Sympathetic blockage or resection helps to relieve the pain of peripheral nerve compression disease after being decompressed.

Objective To explore the regulatory effect of Nervilia fordii Injection ( NFI ) on inflammatory cytokines in rats with lipopolysaccharide ( LPS) -induced acute lung injury ( ALI) , and to explore its possible interfering mechanism . Methods The rats were randomly divided into normal group , model group , Shenmai Injection group, and NFI group. J774 macrophages were stimulated by LPS to establish the cell model in vitro, and in vivo ALI rat model was established by injection of LPS through the sublingual veins. Electronic microscope and enzyme-linked immunosorbent assay (ELISA) were used for observing the proliferation of J774 macrophages, the levels of supernatant inflammatory cytokines secreted by J774 cells, and the levels of serum inflammatory cytokines . Results The proliferation of LPS-induced J774 macrophages was increased , and the secretion of inflammatory cytokines was disordered. Uncontrolled inflammatory reaction occurred in the lung after the rats were administrated with intravenous injection of LPS . Both NFI and Shenmai Injection could inhibit the proliferation of J774 macrophages. NFI could also significantly inhibit the levels of supernatant and serum tumor necrosis factor (TNF) -α and interleukin 6 (IL-6) expression (P<0.05 or P<0.01), and it could increase the level of supernatant IL-10 (P<0.01) and decrease the level of serum interleukin 10 (IL-10) in rats (P<0.05), but couldn’t regulate the secretion of monocyte chemoattractant protein 1 (MCP-1) (P>0.05). Conclusion NFI has better preventive and therapeutic effect for ALI than Shenmai Injection, and its possible mechanism is related with the inflammatory regulation and lung injury relief through the suppression of excessive expression of TNF-α and IL-6 .
