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 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 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.
