Objective: To study the effect of micronutrient fertilizer ratio on the growth and yield of aconite daughter root (the processed daughter root of Aconitum carmichaelii). Methods: Taking A. carmichaelii (Ranunculaceae) as test material, to study the growth and yield of aconite daughter root under the various ratio of Zn, B, Fe, and Mn by the uniform design. Results: To promote the growth and improve the yield of aconite daughter root, the optimum ratio of fertilizer Zn-B-Fe-Mn was 4:1:1:2. Under this ratio, the size of the tuber, the number of the fibrous roots, the length of fibrous roots, the volume of the sub-root, and the dry weight of the tuber, the fibrous roots, and the mother root were significantly or very significantly higher than those under the other fertilizer ratio, while the plant height and the dry weight of leaf were lower than those in the control treatment, with the weight of fibrous roots and the mother roots increased by 24.5% and 25.9% compared with those in the control treatment. The results also showed that there existed negative correlation between the plant height and the yield of per plant, while the dry weight of the fibrous roots and the mother roots showed significantly positive correlation with the yield of per plant. Conclusion: The above mentioned ratio of Zn-B-Fe-Mn as 4:1:1:2 is the best, since it could promote the growth and improve the yield of aconite daughter root more than the other treatment.

OBJECTIVE:To observe the effect of acyclovir on neurological function and cytokines of children with viral menin-gitis. METHODS:Totally 70 children with viral meningitis were randomly divided into control group and observation group. All children were given routine treatment,including defervescence,reducing intracranial pressure and regulating water and electrolyte balance,etc. Based on it,the control group was treated by Ribavirin glucose injection 15 mg/kg,iv,bid;observation group was treated by Acyclovir glucose injection 5 mg/kg,iv,tid. The course for both was 7 d. The clinical data was compared,including the vascular endothelial growth factor (VEGF),matrix metalloproteinase-9 (MMP-9) in cerebrospinal fluid (CSF) and serum,insu-lin-like growth factor-Ⅱ(IGF-Ⅱ) and insulin like growth factor binding protein-3(IGFBP-3) in CSF before and after treatment and the incidence of adverse reactions. There were no obvious adverse reactions during the treatment. RESULTS:After treatment, the VEGF and MMP-9 in serum and the VEGF,MMP-9,IGF-Ⅱ and IGFBP-3 in CSF in 2 groups were significantly lower than before,and observation group was lower than control group,with significant differences(P<0.05). There was no adverse reactions in 2 groups during the treatment. CONCLUSIONS:Compared with ribavirin,acyclovir can more obviously improve the neurological function and cytokines of children with viral meningitis,with similar safety.

The Componential Framework of Creativity,advanced by Amabile,one of significant figures on the social psychology of creativity,comprehensively interpreted the nature and the construct components of creativity.Inspiring by the ideology of Amabile's Componential Framework of Creativity,this study examined whether the science research human resource management practices in today's Chinese science research institutions follow the nature of science research and whether the policy and operation inhibit creativity.It identified the common misconducts happened in human resource selection,development and performance management,and the causes and countermeasures of those misconducts were also explored.The findings will be a source of reference for human resource management practitioners at the science research field of China.
