Objective To develop self-management behavior assessment scale for chemotherapy patients with peripherally inserted central catheter (PICC),and test the validity and reliability of it.Methods In reference to Chronic Disease Self Management Study Measure and its scoring standard by patient education and study center of American Stanford University,in combination with PICC patient self-management content,with reference to the literature,expert assessment,the self-management behavior assessment scale was established.The scale included five dimensions,19 quantitative indicators,a total of 78 entries.From February 2010 to November 2011 192 cases of breast cancer chemotherapy patients with PICC participated in the survey.Results Effective questionnaire was 178 copies,scale of content validity index (CVI) was 0.906,the overall Cronbach alpha coefficient was 0.892.Using factor analysis method,4 common factors were extracted whose characteristic root was greater than 1,and could explain 41.180％ of the total variance,each item on the corresponding factor of load was above 0.3.Conclusions The evaluation scale has good validity and reliability,which can provide researchers with a tool to evaluated and intervene with self management behavior of breast cancer chemotherapy patients with PICC.

Objective To investigate the characteristics of family environment in children with attention deficit hyperactivity disorder (ADHD) in clinics, and analyse the risk factors for ADHD. Methods Two thousand two hundred and ninety-six children with inattention, hyperactivity or unfavourable school performance were subjected to diagnosis with DSM-Ⅳ criteria in clinics. The characteristics of family environment were investigated by self-prepared questionnaires. The risk factors for ADHD were explored by univariate analysis and noneonditioned multivariate Logistic regression analysis. Results Seven hundred and twenty children were diagnosed with ADHD. There were significant differences in family environment between children with ADHD and those without(P<0.05 or P<0.01). The risk factors for ADHD included discord between parents, parental smoking and maternal depression during pregnancy and after delivery, while older age, female, paternal higher educational background were protective factors for ADHD. Conclusion Unfavourable family environment may be associated with the prevalence of ADHD, and special attention should be paid to the family environment in the treatment of ADHD.

Objective To discuss the valuable influence of the total-body massage on the facilitation of the rehabilitation for the women in puerperium.Methods Both Chinese traditional medical total-body massage and the biological information theories and its methodology were employed in dealing with 50 cases of puerperants without contraindications,who had labored naturally 12 hours before and who had received cesarean sections 48 hours before. The results were compared with the control group in which conventional preventive health care for puerperants was adopted.Results Notable differences exist in the aspect of lochia,defecation,lactation and emotions between the two groups.Conclusion Significant benefits can be obtained from the massage to facilitate the rehabilitation of the women in puerperium while promoting their quality of lives and broadening the coverage of services of the preventive health care for the puerperants.

Cell viability of Pichia pastoris was detected by flow cytometry (FCM) with two reagents fluorescein diacetate (FDA) and propidium iodide (PI). Compared with FDA/PI double-stained dot plots and PI single-stained dot plots,the latter could divide dead and living cells into two separate zones,and get the correct proportion. Then PI single-stained method was used to detect the change of cell viability in Pichia patoris fermentation. At glycerol batch and fed-batch phase,little dead cells were detected. At methanol fed-batch phase,cell viability decreased when cell weight increased,and was only 73.8% at 88 h.

Proteolytic degradation has been a severe problem when Pichia pastoris is employed to express recombinant proteins.One alternative method to circumvent this problem is to construct protease gene disruptant.However,the main study of gene disruption is focused on nonrecombinant Pichia pastoris rather than recombinant strain.In our study,we established two different methods to directly disrupt PRC1 and KEX1 gene in recombinant Pichia pastoris.On the basis of this,we further discussed and compared the application and advantages of both methods.

The kinase domain of receptor tyrosine kinase(RTK) ErbB2 was expressed fused with GFP in Pichia pastoris. Recombinant expression vector pPIC3.5K was constructed in Escherichia coli TOP10. The right P. pastoris transformants were screened on his-deficient plates and YPD-G418 plates by turns after electroporation of recombinant vector, and then induced by methanol in baffled shake bottles. The strain with highest protein yield was scaled up in a 5 L fermentor. Recombinant protein was analyzed with tyrosine kinase assay after Ni2+ affinity chromatograph. Results showed that the 100 kD recombinant protein with tyrosine kinase activity was successfully expressed in P. pastoris.

The bioreactor production of recombinant Lateolabrax japonicus growth hormone (rljGH) expressed intracellularly by Pichia pastoris was investigated. A strategy of feeding methanol at the exponential rate was established and the effect of specific growth rate on the rljGH production was examined. The results indicated that the average specific production rate increased and the rljGH production duration decreased as the specific growth rate increased. The maximum specific rljGH production (0.58 mg/g WCW) was achieved at a specific growth rate of 0.029/h. The effect of supplementing ammonium sulfate, peptone and yeast ex- tract on the rljGH production was further investigated. The results indicated that the effects of ammonium sulfate and peptone were not significant. Supplementing yeast extract of 2.5 g/L was advantageous for the rljGH production. The duration of the rljGH production was increased to 23 h from 17 h and the fermenta- tion stability of run-to-run could be improved.
