Plant type characters of truss tomato were studied for exploring the inheritance of leaf angle, and providing a theoretical basis for breeding truss tomato cultivars in compact plant type. Participant truss tomato inbred lines were involved in the cross and backcross for multi-generations, and the mixed major genes plus polygene inheritance model was employed to analyze the inheritance model of leaf angle, plant width, and leaf drooping value. The inheritance of leaf angle and plant width was controlled by one pair of additive major genes plus additive-dominant polygene （D-2）. The additive effect of the major genes controlling leaf angle was 6.51, the additive effect of the polygene was 15.01, the potential ratio was 0.914, and the dominant degree was 0; the heritability of the major genes was 45.61% in B1 generation, 37.29% in B2 generation, and 47.71% in F2 generation. The additive effect of the major genes controlling plant width was 3.08, while the additive effect and dominant effect of the polygene were 3.58 and -1.59, respectively, with the potential ratio of -0.44 and 0 dominant degree; the heritability of the major genes was 23.30% in B1 generation, 20.73% in B2 generation, and 36.11% in F2 generation; leaf-drooping-value trait was controlled by one pair of negative complete dominant major genes plus additive-dominant polygene （D-4）. The additive effect of the major genes was 8.18, the dominant effect was -8.18, the additive effect in the polygene was 3.12, the dominant effect was 19.07, the potential ratio was 6.09, and the dominant degree was -1; the heritability of the polygene was 69.15% in B1 generation, 68.5% in B2 generation, and 49.57% in F2 generation. The improvement on leaf angle and plant width of 173×101 should be focused on the major genes and the selection should be made in early generations, while the improvement on leaf-drooping-value of 173×01 should be made in late generations.

Single crystal copper with large diameter is prepared in vacuum induction furnace under the protection of argon using downward continuous unidirectional solidification method. The process parameters are determined through the experiments. The effects of the process parameters on solidification structure and surface quality of the single crystal copper with large diameter are investigated. The results show that single crystal copper of Φ16 mm with bright surface can be obtained continuously and stably under the following conditions: melting temperature is 1150 ℃, outlet temperature of mold is 750 ℃, cooling water volume is 0.9 m3·h-1, cooling distance is 50 mm, and drawing speed is 0.1 to 0.15 mm·s-1. By X-ray diffraction, the orientation and competition growth of single crystal copper have been analyzed, and the crystallization surfaces of (311), (220) and (111) are eliminated sequentially during evolutionarily processing. The final growth face of single crystal copper is (200). its direction of crystallization is [100]. Effect of solid-liquid interface on crystal growth has been investigated, the micro-convex interface to liquid is the key to getting single crystal copper.

To develop beam splitters for soft X-ray laser Michelson interferometer at 13.9 nm, Mo/Si multilayers of 100 nm thickness deposited on both sides of silicon nitride were fabricated by using DC magnetron sputtering. Initial evaluation of their reflectivity and transmission showed that reflectivity and transmission were above 10% and 25%. The broadband analyzers have been designed, fabricated and characterized for 13～20 nm polarization measurements. The measured results are in good agreement with the design. The supermirrors with different angular intervals at 0.154 nm have been designed, fabricated and characterized.

Objective： To examine the association of genetic variants with characteristic symptoms of type 2 diabetes mellitus （T2DM）. Methods： A matched case-control study was performed to investigate the association between common variants in four genes （CDKAL1, GLIS3, GRK5, and TCFTL2） and symptoms of T2DM. Symptoms were examined with questionnaire for 710 subjects. Genomic DNA was extracted from peripheral blood mononuclear cell by salting-out procedure. Genotyping was carried out by direct sequencing of the unpurified polymerase chain reaction products. Result： Most of the T2DM patients pressented characteristic symptoms, such as feeling weak in limbs （P=0.0057）, hand tremor （P=0.0208）, bradymasesis （P=0.0234）, and polyuria （P=0.0051）. Some of the T2DM patients shared characteristic symptoms, such as desire for cold drinks （P=0.0304）, polyphagia （P=0.0051）, and furred tongue （P=0.028）. The impaired glucose regulation （IGR） cases took only one characteristic symptom of frequent micturition （P=0.0422）. GLIS3 rs7034200 and GRK5 rs10886471 were significantly associated with increased T2DM risk （GLIS3 rs7034200 under dominant model： P=0.0307; GRK5 rs 10886471 under recessive model： P=0.0092）. However, only the rs10886471 polymorphism in GRK5 showed a significant effect on both differentiated symptoms and T2DM risk. The C-allele was involved in both dampness-heat encumbering Pi （Spleen） syndrome （P=0.047） and qi-yin deficiency syndrome （P=0.002） via increased GRK5 expression. Conclnsions： Both T2DM and IGR exhibited its corresponding characteristic symptoms. The variants of GRK5 were involved with both qi-yin deficiency syndrome and dampness-heat encumbering Pi syndrome.

Adinbitor was cloned from Agkistrodon halys brevicaudus stejneger and characterized as a novel disintegrin. In this study, total RNA was extracted from venom gland and used in RT-PCR to generate a cDNA which is 219 bp long. The sequence encoded a polypeptide composed of 73 amino acids, including 12 cysteines, an RGD motif, and the signature motif of disintergrin. Recombinant Adinbitor (rAdinbitor) was expressed in E. coli and purified by using the His?Bind affinity chromatography. The IC50 for inhibiting human platelet aggregation and bFGF-induced proliferation of ECV304 cells was 6 μΜ and 0.89 μΜ respectively. Furthermore, Adinbitor significantly inhibited angiogenesis both in vivo and in vitro. Taken together, these results suggested that Adinbitor had typical functions of disintegrins.
