ABSTRACT
Objective To investigate the rehabilitation promoting factors in stroke patients and to provide references for the design and implementation of effective intervention for rehabilitation of stroke patients.Methods In-depth interviews were conducted among eight stroke patients,and interview data were collected and analyzed.Results Five themes were identified through analysis and classification of the interview data:practical rehabilitation goals,effective rehabilitation training behaviors,overcoming abandonment behaviors and negative emotions,suitable support system,and proper self-adjustment.Conclusion The rehabilitation promoting factors for stroke patients are performing effective rehabilitation training towards effective rehabilitation goals.In this process,patients need to rely on appropriate social support and patients' self-adjustment to overcome abandonment behaviors and negative emotions.These factors form a force to promote rehabilitation during the process of rehabilitation.
ABSTRACT
Objective To analyze the stability of chromosome variant ratio of three available transformed corneal cell lines. Methods Chromosome specimens of transformed cells including human corneal epithelial cells(HCE),bovine corneal endothelial cells(BCE) and rabbit corneal epithelial cells(RCE) were prepared by a direct method using regular Giemsa staining. Chromosomes of cells in metaphase were counted under the microscope. Then, the variant ratio of chromosomes and their nuclear types were analyzed. Results The chromosome numbers were 56 to 65, 27 to 34 and 74 to 88 for HCE, BCE and RCE, respectively. Chromosome numbers in the three commonly used and transformed corneal cell lines were changed in comparison to their parent tissues. Conclusion Genotyping study may provide important information for using HCE、BCE、RCE in functional studies.
ABSTRACT
<p><b>OBJECTIVE</b>In order to investigate the leukemogenic potential of NUP98-HOXA9 fusion gene in vivo.</p><p><b>METHODS</b>Molecular cloning technology was used to construct NUP98-HOXA9 transgenic plasmid and NUP98-HOXA9 transgenic mice were generated. The genotype and phenotype of the NUP98-HOXA9 transgenic mice were analyzed by PCR, RT-PCR and colony-forming assay. The effect of N-ethyl-N-nitrosourea (ENU) stimulation on the transgenic mice was analyzed by peripheral blood count, bone marrow (BM) cells morphology pathological examination.</p><p><b>RESULTS</b>The transgenic expression was detected in 5 independent lines of NUP98-HOXA9 transgenic mice, but no expected phenotypes was found in 2 year follow-up. Upon ENU stimulation, 2 of 10 transgenic mice developed myeloid leukemia, suggesting that NUP98-HOXA9 transgenic mice have increased susceptibility to ENU mutagenesis in leukemogenesis.</p><p><b>CONCLUSION</b>The fusion gene expressed in BM cells of NUP98-HOXA9 transgenic mice. It seems that the expression of the fusion gene is insufficient to trigger leukemogenesis. However, the increased susceptibility to ENU mutagenesis suggests that NUP98-HOXA9 fusion gene might play a potential role in leukemogenesis.</p>

<p><b>OBJECTIVE</b>In order to investigate the leukemogenic potential of NUP98-PMX1 fusion gene in vivo.</p><p><b>METHODS</b>NUP98-PMX1 transgenic mice were generated, in which the fusion gene was driven by hCG promoter and expressed in myeloid cells at early stage of differentiation. Molecular cloning technology was used to construct NUP98-PMX1 transgenic plasmid. The genotype and phenotype of the NUP98-PMX1 transgenic mice were analyzed by PCR, RT-PCR, peripheral blood count (PBC), bone marrow (BM) cells morphology and pathological examination.</p><p><b>RESULTS</b>NIH3T3 cells transfected with NUP98-PMX1 fusion gene grew faster, formed colonies in soft agar, and developed tumors in 10 inoculated nude mice. Among 8 disordered NUP98-PMX1 transgenic mice, 4 developed myeloid leukemia-like phenotype, including 3 resembling human chronic myeloid leukemia.</p><p><b>CONCLUSION</b>NUP98-PMX1 has oncogenic activity and plays a crucial role in leukemogenesis.</p>

<p><b>OBJECTIVE</b>To investigate the relationship between haplotypes of multilocus markers and ankylosing spondylitis (AS).</p><p><b>METHODS</b>Five families with AS were recruited from Shanghai area. Eleven microsatellite markers around D6S276 were analyzed by Linkage package and by Cyrillic package.</p><p><b>RESULTS</b>Fine linkage analysis showed the significant Lod score values with D6S276 was 3.8821, Lod score values with D6S1691 and D6S1618 near D6S276 were larger than 1.5. The crossover value in 5 pedigrees was 14%. The haplotype analysis showed that the regions between D6S1691 and D6S1618 were associated with AS.</p><p><b>CONCLUSION</b>The regions of D6S1691-D6S276-D6S1618 may harbor a susceptible gene of AS. The specific haplotypes of different pedigrees may play an important role in the presymptomatic diagnosis for AS.</p>

<p><b>OBJECTIVE</b>To study the biological function of fusion gene HRX-EEN and its role in leukemogenesis, and to provide an ideal animal model for anti-leukemia drug screening.</p><p><b>METHODS</b>HRX-EEN fusion gene was constructed by use of three different DNA fragments, and it was inserted into hCG transgenic vector. G(0) transgenic mice were obtained by microinjection of the recombined DNA into the pronucleus of zygotes, followed by implantation of the injected zygotes into pseudopregnant mice. The integration of the transgene was tested by PCR and its expression by reverse transcription-polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>The sequence of recombined HRX-EEN gene was confirmed by sequencing. PCR testing revealed a total of 7 G(0) transgenic mice, these mice were then mated with C57 wild type mice. Except mouse No. 35 that died, the others all had their F1 offsprings. From these 6 lines of transgenic mice, HRX-EEN gene was found to be stably expressed in 3 lines by RT-PCR. Up to now, all transgenic mice expressing the fusion gene have no obvious abnormal phenotypes.</p><p><b>CONCLUSION</b>A transgenic mice model in which the HRX-EEN fusion gene can be stably expressed has been established.</p>
