Objective To explore the methods of the standardized management used in humanistic nursing care and to assess its effects.Methods Measures of the standardized management began to be used in such care at the hospital since January 2013.Questionnaires of patient satisfaction with nursing care for inpatients and those discharged were used to assess the effects of the standardized management measures periodically and synthetically.Results The patient satisfaction with humanistic nursing care keeps increasing year by year from 2013 to 201 5.The differences among three sets of data are statistically significant(P < 0.05 ).Conclusions Humanistic nursing care calls for promotion of standardized management.It is high time to build such a standardized management system at the hospitals.

In order to construct generally efficient cell immortalization vector, pTP-hTERT, we modified the traditional piggyBac (PB) transposon using artificial synthesis, PCR and enzyme digestion. The modified vector contained the necessary transposon elements, a PB transposase expression cassette, a co-expression selectable element and a human telomerase reverse transcriptase (hTERT) expression cassette. The co-expression selectable element had two markers, enhanced green fluorescent protein (EGFP) gene and puromycin-resistance (Puro) gene, linked by porcine teschovirus-1 2A peptide (P2A). To validate the functionality of vector elements, we transfected pTP-hTERT into HEK293 cell, selected the positive cell clones and then conducted RT-PCR, Western blotting (WB) and Tail-PCR, methylene blue staining and statistic analysis on selected cells. The results of sequencing and cell culture show that the pTP-hTERT was constructed successfully and the positive cell could be selected by puromycin. The WB results, P2A cutting EGFP and Puro fusion protein with high efficiency, reflected the selectable element worked. The sequencing result of Tail-PCR confirmed the vector integrated into the genome through transposition. The results of methylene blue staining and statistic analysis indicated the clone of positive cells triggered by pTP-hTERT significantly increased (P < 0.01) compared with control group. The construction of pTP-hTERT provides an efficient tool for establishing immortalized cell lines and a demonstration for building other eukaryotic plasmids.

Objective To study whether ORF3 coded by fap1-orf4 gene locus of Streptococcus pa-rasanguis is involved in the regulation of Fap1 glycosylation and maturation and to investigate whether ORF3 influences Streptococcus parasanguis adhesion. Methods A gene replacement strategy was adapted to con-struct orf3 alleic replace mutant of Streptococcus parasanguis. Complementation assay and Western blot were used to test Fap1 expression levels. Whole saliva-coated hydroxyapatite (SHA) adhesion assay was adapted to determine Streptococcus parasanguis adhension. Results (1) Non-polar was found in strain VT1774, the orf3 alleic replace mutant of Streptococcus parasanguis. (2) Western blot showed that mature Fapl (Mr about 220 × 103) disappeared and were substituted with high molecular weight Fapl (Mr about 470 × 103) in strain VT1774, furthermore, complementation assay showed VT1775, the complementation strain of VT1774, re-stored mature Fapl expression. (3) The binding ability reduced significantly in strain VT1774. Conclusion ORF3 coded byfapl-orf4 gone locus was required for Fap1 glycosylation and maturation in Streptococcus pa-rasanguis, orf3 alleic replacment resulted in Fap1 glycosylation and mature disorder and decreasing of adhen-sion ability of Streptococcus parasanguis.

Objective To investigate whether glucosyltransfernse(GTF) and open reading frame 4 (ORF4) coded by fap1-orf4 gene locus of Streptococcus parasanguis was involved in the regulation of Fap1 glycosylation, and mature and to determine whether there was interaction between GTF and ORF4. Methods A gene replacement strategy was adapted to construct gtf and orf4 allele replace mutant of S. Parasanguis. Complementation assay and Western blot were used to test fap1 expression levels. Yeast two-hybrid analysis and GST pull down assays were adapted to determine the interaction between GTF and ORF4. Results (1) Compared with wild S. Parasanguis, mature Fapl (Mr about 220×103) disappeared and were substituted with high molecular weight Fapl (Mr about 360×103) in gtf or orf4 alleie replace mutants of S. Parasan-guis. Complementation assay showed that pVPT-GFP-gtf and pVPT-GFP-orf4 restored mature fap1 expression in gtf or orf4 alleie replace mutants, respectively. (2) With Yeast two-hybrid analysis, the eotransformants, AH109/pAD-Gtf+pBD-orf4 and AHlOg/pAD-orf4+pBD-gtf growed on SD-LTHA selective ngar plate after streaked, reversely, the eotransformants, AH109/pAD+pBD-orf4,AH109/pAD+pBD-gtf、AH109/pBD+ pAD-orf4、AH109/pBD+pAD-gtf did not grow on SD-LTHA selective agar plate, furthermore, the cotrans-formants, AH109/pAD+pBD-orf4 and AH109/pAD-orf4+pBD-gtfshowed blue during X-α-gal assay. (3) GST pull down assay confirmed the direct interaction between GTF and ORF4. Conclusion There is inter-action between GTF and ORF4 coded byfapl-orf4 gene locus of S. Parasangnis and the formation of the GTF and ORF4 complex was required for the glycosylation and mature of Fapl in S. Parasanguis.

Objective:To investigate the immunogenicity of SARS-CoV N DNA vaccine and the feasibility of live-attenuated Salmonella typhimurium as the carrier to deliver the N DNA vaccine.Method:The recombinant attenuated salmonella strain CS022 harboring the pcDNA-N DNA vaccine was constructed.And mouse was immunized with the recombinant strain via intranasal and oral routes.Cellular and humoral immune responses were assessed by ELISA,lymphocyte proliferation assays,ELISPOT and FACS.Result:The oral immunization with the transformed salmonellae elicited strong immune responses mainly including high level of N-specific antibody,a dramatic activation of IFN-?-secreting cells,a high level of lymphocyte proliferation,and a high level of activated CD8+ T cells.Conclusion:Live-attenuated Salmonella typhimurium could effectively deliver the SARS-CoV N DNA vaccine in vivo.These encouraging pre-clinical data provide a rational basis for undertaking a new immune style to investigate SARS vaccine.

To explore a new strategy for further optimization to the C-3 bioisteric heterocyclic ring of fluoroquinolones,twelve novel fluoroquinolone C-3 s-triazole Schiff-base carboxylic acid derivatives(7a-71) were designed and synthesized with both functionalized sulfanylacetic acid and Schiff-base moieties as the modified side-chain for the C-3 bioisosteric s-triazole ring of pefloxacin(1).The structures were characterized by elemental analysis and spectral data,and the in vitro anti-tumor activity of the title compounds against SMMC-7721,L1210 and HL60 cell lines was evaluated.The preliminary pharmacological results demonstrated that the title compounds possessed more significantly anti-proliferative activity than either the parent 1 or the corresponding amine intermediates(6).In particular,the title compound bearing a fluorine atom (7j) and compound bearing a nitro group attached to benzene ring (71) were comparable to the control doxorubicin against SMMC-7721 cells with an IC50 value of micro-molar concentration,respectively.It suggests that s-triazole ring modified with functional side-chain moieties instead of the C-3 carboxylic group is favorable to the improvement of antitumor activity.

Peking University Health Science Center has various characteristics of educational manage-ment practice such as clear three level management, diversified management training and strict quality control, and at the same time there exist many deficiencies, such as lack of the implementation of management regulations and the requirements caused by multi-level management and management quality having ups and downs be-cause of human factors and etc.. By introducing life cycle management into national continuing medical educa-tion project management, we make management run through the whole life cycle of national continuing medical education project, namely five aspects of management from reporting and publishing, planning and publicity, holding and supervision, graduation and certificates, as well as summary and feedback, which plays an impor-tant role in standardizing the national continuing medical education project and improving the quality of the project.

Conclusions The application of E- learning in the training of public health emergencies is beneficial to help the medical staff to obtain and share information resources more conveniently, to enhance the ability of the clinic medical workers of understanding the condition of emergent public health affairs, to elevate the grades of theoretical learning of the relevant knowledge and to improve the management level of training, training effect and efficiency.

Objective To investigate the effect of continuing nursing on elderly patients with high risk of pressure sores. Methods High-risk elderly patients with pressure sores healed in our hospital in January 2014 to December 2014 were divided into control group and observation group with 130 cases in each group by random number table. The control group received routine follow-up service, while the observation group were intervened by continuing nursing care. To observe the differences before and after the interventions in both groups on the patient's quality of life and the incidence of pressure sores. Results There was statistically significance on mental function scores (t=12.393, P=0.000), social function score (t=8.459, P=0.000) and overall quality of life score (t=12.750, P=0.000) between the two groups after the interventions. Meanwhile, there was no statistically significance on material life score (t =-1.913, P=0.057) and physical function score (t=-0.328, P=0.744). The difference of the re-occurrence of pressure sores in the two groups was statistically significant (χ2=35.96, P=0.000), either. Conclusions Continuing nursing intervention can obviously reduce the risk the re-occurrence of pressure sores on high-risk elderly patients, in particular to improve the quality of life aspects of mental function and social function in patients, meanwhile with no obvious improvement in that of material life and body functions.
