AIM: To investigate the potential role of 14-3-3 tau in trophoblast cells on invasiveness. METHODS: 14-3-3 tau expression was detected in first-trimester villi, deciduas and human trophoblastic cell line (BeWo) by immunohistochemistry. Small interference RNA (siRNA) targeting 14-3-3 tau was transfected into BeWo cells. The effects of down-regulated 14-3-3 tau on invasion of human trophoblasts cell line BeWo were examined by matrigel invasion assay, and the transcription, translation of E-cadherin and snail were estimated by RT-PCR or Western blotting. U0126 was used to detect the extracellular-signal related kinase 1/2 (ERK1/2) function on down-regulation of 14-3-3 tau induced cell invasion. RESULTS: 14-3-3 tau was detected in the invasive trophoblastic cells in the first trimester villi and that invaded to the deciduas. BeWo cells also expressed 14-3-3 tau. Down-regulation of 14-3-3 tau increased the invasive cell-number of BeWo, as well as the expression of snail, and inhibited E-cadherin. U0126 inhibited the enhanced invasiveness in these cells induced by the down-regulation of 14-3-3 tau. CONCLUSION: 14-3-3 tau may regulate the invasiveness of human trophoblastic cells through ERK1/2 signaling pathway.

Objective To analyse a novel splice mutation in EXT1 gene of hereditary multiple osteochondroma, and study its pathogenic mechanism.Methods In April of 2013, the proband was hospitalized from the outpatient department with multiple joint deformity for more than 20 years, peripheral blood of the proband and his parents were collected and genomic DNA was extracted .Coding regions and adjacent intron sequences of EXT1/EXT2 genes in genomic DNA of the family members were amplified and sequenced.Bioinformatics was used to analyze the mutation from sequencing .cDNA from peripheral blood of the proband ,the mother and normal control was made respectively as a template for amplifying coding regions of EXT1 gene, and the product was T-A cloned and sequenced.The abnormal transcripts of each group were counted and analyzed using chi square test to study the pathogenic mechanism of the mutation .Results Sequencing results of family members revealed that there was a heterozygous deletion mutation ( c.1284 +2del) in the 5′splice site of intron 4 in EXT1 gene of the proband and his mother .Bioinformatics predicted that exon 4 of EXT1 gene was skipping or spliced aberrantly due to the mutation .T-A clone and sequencing results as well as the statistical analysis suggested that there was a significantly higher proportion of transcripts with skipping exon 4 in the proband and his mother compared with the normal control (P=0.000, P<0.01).Conclusions c.1284+2del in EXT1 gene is reported for the first time internationally , which results in a considerable number of abnormal transcripts with skipping exon 4 in EXT1 gene, thereby influences the normal transcription and translation of EXT1 gene.

Objective To explore the experience of nursing patients with Crohn’s disease.Method The nursing histories of 80 patients with Crohn’s disease were retrospectively reviewed to analyze and summarize the measures for nursing them.Result After active treatment and effective nursing,all the patients were improved and discharged.Conclusion Effective nursing is of positive significance to improve the curative effect of Crohn's disease.

Objective To understand the support effect of the resources and services provided by the library on the scientific research of medical postgraduates. Methods Taking 150 graduate stu-dents in Chongqing Medical University as the research object, through questionnaire survey and inter-view method, the characteristics of medical graduate students' selection of document resources, as well as their application of the resources and services provided by the library were investigated. Results 65% (98/150) of students chose Chinese literature as the preferred source of information, 6% (9/150) of graduate students did not borrow books at the library, 54% (81/150) of graduate students chose library website as the data retrieval entrance at the time of obtaining the preferred document, 9% (14/150) of students did not participate in the library reader training. Conclusion Library resources are still the first choice for the graduate students to obtain the literature, and the library should be improved in the aspects of resource allocation, service mode, in order to meet the needs of graduate students' scientific research.

Objective To know the impact of nursing intervention mode of parent-child interactive on the adaption of postpartum family roles.Methods One hundred families (maternal,husbands,baby at birth) were divided into the intervention group and the control group.The intervention group was cared by the responsibility nurses who were trained to master the parent-child interactive nursing intervention.The control group was cared by conventional nursing methods.The role adaptation of the fathers and the mothers of the two groups,and self-confidence of the parents to take care of newborns were observed.Results In the intervention group,the role adaptation of the fathers and the mothers was better than the control group; self-confidence of taking care of the newborn was better than the control group.The sleep time of the newborns was prolonged and the crying times were less than the control group.Conclusions The parent-child interactive nursing intervention model can help the family to adapt to the father and the mother role as soon as possible; teach the parents to comprehensively understand newborns,give stimulation of touch,sight,hearing,smell,so as to achieve positive response of newborns and increase the confidence of rearing newborns of the parents.

Objective To establish the murine animal model for acute graft-versus-host disease after allogeneic hematopoietic stem cell transplantation (HSCT). Methods T cell-depleted (TCD) BM cells from allogeneic C57BL/6 mice were harvested and prepared from the marrow of the femurs and tibias. Age of 4 to 6 weeks’ BALB/c mice received 900 cGy total body irradiation ( TBI) from a 137Cs source. Two to four hours later,the mice were injected intravenously ( i. v. ) 5 × 106 TCD-BM cells with 1. 25 × 106 or 2. 5 × 106 or 5 × 106 splenic cells from allogeneic C57BL/6 mice,and respectively divided them into experimental group 1,experimental group 2 and experimental group 3. TCD-BM only was used as the negative control group of GVHD. Ten mice were used for each group. The establishment of aGVHD model was evaluated with a clinical GVHD scoring system,survival rate and target-organ damage. Results On 7 to 14 days after transplanta-tion,the typical clinical GVHD manifestation of severe diarrhea,hogback,activity reduced and ruffling were observed in experimental group 2. Furthermore,the aGVHD target organs of colon,lung and liver were harvested and made histological paraffin sections,then the obviously path-ological tissue damages of GVHD were detected under microscope. And the survival rate was lowed down to 0 on 45 days after transplantation in experimental group 2. On the contrary,no obviously clinical manifestation of aGVHD were observed in the control group,experimental group 1 and group 3. On 60 days later, the survival rate was 80% in experimental group 1 and 100% in control group. However,no mice was sur-vived on 10 days later in group 3. Conclusion BALB/c mice aGVHD model after allogeneic HSCT is successfully established by injecting i. v. 5 × 106 TCD-BM cells with 2. 5 × 106 splenic cells from allogeneic C57BL/6 mice.
