The inhibin a gene、 the bone morphogenetic protein 4 (BMP4) gene and the bone morphogenetic protein 7 (BMP7) gene were studied as candidate genes on the prolificacy of Small Tail Han sheep. Single nucleotide polymorphisms of 5 ' regulatory region、 exon 1 of INHA gene;exon 2、 exon 3 and exon 4 of BMP4 gene and exon 2、 exon 3 of BMP7 were detected in high fecundity breed and low fecundity breeds (Chinese Merino sheep, Corriedale sheep and South African Mutton Merino sheep) by PCR-SSCP. The results indicated that there was a mutation (316C→T) in 5' region of INHA gene in Small Tail Han sheep, Chinese Merino sheep and Corriedale sheep, the same mutation did not exist in South African Mutton Merino sheep.

The comparative investigation of the characteristics of deformation and AE were conducted and the results are presented as followed: 1. The characteristics of rock AE are correlated to the strength, joints, cracks, and the size and hardness of crystalline grain. 2. The sequence of AE can be divided into four phases: beginning phase, tempestuousness phase, drop phase and dreariness phase. The loss and the duration of the phases are correlated to the rock character and flaws in the rock. 3. The AE rate characteristics are not almost concordant with the AE energy rate. 4. Besides the homogeneity, the strength of rock contributes the activity of AE. The higher the strength is, the lower the activity is. 5. There is a dreariness phase before the failure of most kinds of rock. 6. Whether the precursor is obvious is correlated to rock the character, and the precursor of AE rate is more apparent than the precursor of AE energy rate comparatively.
通过对比研究这六种不同岩石的变形和声发射特征发现,岩石声发射受到岩石强度、节理裂隙和晶粒软硬大小等的影响;岩石声发射过程存在初始区、剧烈区、下降区和沉寂区,各个阶段是否存在及持续时间与岩石强度、内部缺陷等有关;岩石的声发射事件率特征与能量率特征并不完全一致;岩石的声发射活性除了受其均匀性影响外,还受到岩石的强度影响,强度越小,声发射活性越强;大多数岩石破坏前存在一声发射沉寂区;岩石的破坏前兆是否明显跟岩性有关,相比较而言,岩石破坏时的声发射率前兆比声发射能量率前兆更为明显一些。

Sample collection: Two hundred and fifteen sera samples of normal population were collected from the peripheral blood of healthy blood donors of Shenyang, and the sera were separated by centrifugation after blood clotting; The patients sera were collected from the outpatients and inpatients of No. 1 hospital of China Medical University and the Second hospital of Jilin University. Syphilis was confirmed by clinical and serum test of TPHA and RPR; That of pemphigus vulgarism was confirmed not only by clinical, histopathological examination, but also by direct and indirect immunofluorescence test. DIF test on lesion or non-lesion skin showed immunoglobin and/or C3 deposits in the intercellular space of epidermis, and IIF test showed positive anti- intercellular antibody in patient serum using mouse's or rat's tongue or esophagus as substrate.

And they systematically studied the effect of the activate spleen-energy law on digestive and absorptive function, it is confirmed that the activate spleen-energy law have significant regulation effect on the action and secretion of gastrointestinal tract. Recently, we established the juvenile rat model with anorexia by imitating the major cause of children and found that the CCK-8S concentration in hypothalamus and periphery blood of the anorexy model was obviously increased .We also found the appestat that the spontaneous discharge frequency of LHA neurons was decreased and the spontaneous discharge frequency of VMH neurons was increased.

CML is cytogenetically marked by the philadelphia chromosome, which originates from a reciprocal translocation between chromosome 9 and 22 and is molecularly marked a chimeric bcr-abl gene, resulting from juxta-positive of the abl proto-oncogene on chromosome 9 with the bcr gene, which is normally located on chromosome 22. The chimeric bcr-abl gene expression an 8. 5kb hybrid mRNA transcript giving rise to a 210-KD fusion protein (P210〓) with increased tyrosine kinase activity. P210〓 plays a key role in the pathogenesis of CML. The continuous cell line K562 was established from the pleural effusion of a 53-year-old female with CML in terminal blast crisis, and was a human erythroleukemia line, contained Ph chromosome.
