Transgenic animal model provide a good platform to research the pathogenesis and therapy of chronic myelogenous leukemia (CML). To date, a number of BCR/ABL transgenic animal models have been established using different promoter or tetracycline-controlling system. Some of them appear the characteristics of human CML, which have contributed greatly to research the pathogenesis and therapy of CML. In this article, the researching progress, advantage and drawback, application of BCR/ABL transgenic animal model are reviewed.

In this article we built formula database of health food containing Gardeniae Fructus with Traditional Chinese Medicine Inheritance Support System (V2.0). And on this basis, use data mining method such as association rules of the software, to analyze commonly used formula raw materials or materials combination of formula containing Gardeniae Fructus and raw material application having assisted function formula to protect chemical liver injury. The result shows that of the 71 health food formulas containing Gardeniae Fructus, most used materials are Gardeniae Fructus, Lycii Fructus, Angelica Sinensis Radix, Poria and so on. Commonly used materials combination mostly are Gardeniae Fructus and Lycii Fructus, Gardeniae Fructus and Angelica Sinensis Radix, Gardeniae Fructus and Poria, Gardeniae Fructus and Paeonia. There are nearly 18 healthcare functions of the health food containing Gardeniae Fructus, and most of these are assisted functions to protect chemical liver injury, and then immune modulating function. Of 23 formulas containing Gardeniae Fructus having assisted function formula to protect chemical liver injury, Gardeniae Fructus usually combined with traditional Chinese medicine which nourishs blood and liver such as Pueraria, Lycii Fructus, Hawthorn, Paeonia and Turnjujube. Analyzing formula raw materials application of health food containing Gardeniae Fructus contributes a lot to the further development and utilization.

P210(bcr/abl) fusion gene is indispensable for generation and progression of chronic myeloid leukemia (CML). Small molecule inhibitors, such as imatinib, are effective for P210(bcr/abl) gene mediated CML, but drug resistance may occur. The unique fusion junction of P210(bcr/abl) gene is an attractive target for therapeutic intervention using RNA interference (RNAi). This study was purposed to constructed the BaF3 cell line by viral vector which can stably express P210(bcr/abl) shRNA and P210(bcr/abl) mRNA at the same time, and investigate the effect of lentiviral-victor-delivered shRNA on P210(bcr/abl) gene expression. The infective rate of lentiviral vector on BaF3 cells with P210(bcr/abl) gene was assayed by fluorescent microscopy; the cell proliferation ability was determined by trypan blue exclusion; the P210(bcr/abl) mRNA and protein expressions were detected by RT-PCR and Western blot respectively. The results found that stable expression of the P210(bcr/abl) shRNA resulted in obvious inhibition of P210(bcr/abl) mRNA and protein expression and increased sensitivity of these P210(bcr/abl) gene transformed Ba/F3 cells to imatinib. The IC(50) to imatinib in these cells decreased < 50% as compared with Ba/F3-P210(bcr/abl) cells which did not express P210(bcr/abl) mRNA. The survival time of the lethal dose irradiated mice induced by intravenous injection of these Ba/F3 cells was longer than the other group induced by Ba/F3-P210(bcr/abl). It is concluded that stable expression of shRNA targeting the P210(bcr/abl) gene fusion junction may potentiate the effects of conventional therapy for CML.

Objective To evaluate the short term effect of bipolar arthroplasties in aged cases with intertrochanteric fractures.Methods There were 23 males and 15 females(at age of 70-93 years, average 76 years)with unstable intertrochanteric fractures treated with the third generation cementing techniques and bipolar arthroplasties that were followed up for average 2.4 years.The clinical effect was evaluate with Harris scale,X-ray films and complications.Results Of all,34 cases(89.5%)could walk freely.The average Harris scale was 84.2 points.The average period until walk with full-weight load was 5.6 weeks.The greater trochanters was united in 35 cases(92%)during average 4.2 months.No peri-prothetic ossteolysis and loosening or subsidence occurred.Conclusions Cemented bipolar arthro- plasty has good advantages of reduced laying up period and few complications.The short-term outcome is satisfactory hut the long-term outcome needs deeper observation.

WRKY transcription factors are novel transcriptional regulatory factors, which play an important role in regulating plant development, metabolism and other physiological processes. In this study, a new Dendrobium officinale WRKY transcription factor, designated as DoWRKY1 was cloned by using RT-PCR and RACE (GenBank Accession No. KF953910). Bioinformatic analysis demonstrated that, the full-length cDNA of DoWRKY1 was 1,704 bp. And DoWRKY1 contained a 1,629 bp open reading frame (ORF) that encoding a peptide of 542 amino acid residues. The putative DoWRKY1 protein contained two conserved WRKY domains and it belonged to the group I WRKY family protein. Yeast one-hybrid experiment showed that DoWRKY1 had transcriptional activation ability in yeast, and it could activate the expression of downstream report genes (His3 and Ade2). Semi-quantitative RT-PCR experiment showed that DoWRKY1 expressed in roots, stems, leaves and protocorm-like bodies. Real-time qRT-PCR proved that DoWRKY1 could be induced by methyl jasmonate (MeJA) and chitosan (Chitosan), and the expression level of this gene can reach the expression peak at 2 h and 1 h, respectively. These results are useful for further determination of the regulation function of this gene in secondary metabolism of D. officinale.
