The results of two experimental tests showed that: the optimum application dosage of chinaberry element biological compound fertilizer to the corn is 1 500 kg per hectare; With the same content of nitrogen, phosphorus, and potassium, chinaberry element biological compound fertilizer has the effect not quite obvious to increase production compared to the general ternary fertilizer and formula fertilizer, but the application of fertilizer can increase the resistance to diseases and pests of corn, degradation of toxic substances such as pesticide residues and heavy metals.

试验结果表明，玉米施用楝素生物复合肥，每公顷1 500 kg为最佳施用量；在同样氮、磷、钾含量的情况下，楝素生物复合肥同常规三元肥、配方肥相比有一定增产效果，但效果不十分明显，不过施用复合肥能提高玉米的抗病虫能力、降解农药残留和重金属等有毒物质，是生产绿色玉米的理想肥料。

The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

Combined with animal model of peradaptation to myocardium ischemia , the research observed the level of enzymatic dynamics of myocardium, SOD,MDA,ET and correlation peptide of calcitonin gene in peripheral blood and cardiac function, apoptic cell and expression of apoptosis regulatory gene, ultrastructure of myocardium with BIOPAC16, in situ end labeling and hybridism, optic microscope and electron microscope. The study of animal model of peradaptation to myocardium ischemia illustrated that the peradaptation and pretreatment with Wenxin capsule could be positively protective for the injury of ischemia reperfusion. The protection is mainly reflected by reduction of infarction area, correction of heart rhythm abnormality of ischemia reperfusion, melioration of the contraction and relaxation function of myocardium, recovery of the subcellular structure and themelioration of the abnormality of biochemical and bioactive substance in the myocardium.

New antifungal agents have been developed over the past years based on the discovery of many new target sites of Candida albicands. For example, Echinocandins, aiming at the cell wall of Candida albicands, showed strong antifungal activities to fluconazole resistant candidas and fungal biofilm. Moreover, because β-glucan synthase does not exist on the cell membrane of mammalian cells, Echinocandins has a low toxicity and a promising clinical future. Though the mechanism of Histatin is not clear, it has strong activity not only on candida resistant of polyene and azole, but also to Candida parapsilosis, Candida krusei and Cry ptococcus neoformans. Berberine and Ocimum gratissimum L. were also found to have prominent anti-fungi activities.
