Objective Peritoneal dialysis can be done at home , however , its clinical follow-up quality is lower compared with hemodialysis due to the lack of detailed follow-up system and professional management team for post-discharge nursing care .The article aimed to explore the effect of a nurse-led integrated specialized disease management model in the follow-up of peritoneal dialysis patients . Methods Nurse-led integrated specialized disease management model was provided for 270 patients with peritoneal dialysis (PD) from January 2012 to May 2013.Self-designed questionnaire on diasease knowledge and self-care assement questionnaire were used for patients to evaluate their self-care ability and understanding of disease knowledge .Regular follow-up continued . Results The patients′understanding of disease knowledge was on the rise at 1st day before discharge, 1st month and 3rd months after discharge. After the application of nurse-led integrated specialized disease management model , the patients′regular clinical follow-up rate was in-creased from 78.3% to 88.6%.The patients′self-care ability improved gradually at 1st day before discharge , 1st month and 3rd months after discharge , which was of significant differences . Conclusion The nurse-led nurse-led integrated specialized disease management model can improve peritoneal dialysis patients′self-care ability and reduce their medical expense , which is of clinical sig-nificance .

Objective To explore the effect of antidepressant intervention on mood state of at or around the time of radiation therapy. Methods 62 hospitalized patients with cancer receiving radiotherapy were divided into two groups by the order of the time when they accept the radiotherapy which called intervention group ( antidepressant fluoxetine group) and control group. And the two groups patients filled out Hamilton Anxiety Scale( HAMA )and Hamilton Depression Scale (HAMD) at or around the time of radiation therapy to investigate the effects of fluoxetine on anxiety and depression. Results The scores of HAMA and HAMD showed that there was no differences between the intervention group and the control group before the radiotherapy. There was significant difference during the radiotherapy ( 6.41 ± 2.30 ) vs ( 9.29 ± 5.62 ); ( 8.80 ± 3. 048 ) vs ( 12.22 ± 8.32 ) and two weeks after the end of the radiotherapy ( 4.90 ± 1.71 ) vs ( 12.32 ± 7.24 ); ( 6.83 ± 2.47 ) vs ( 16.09 ± 8.61 ) between antidepressant fluoxetine group and control group(P ＜ 0.05 ). Conclusion More attention should be paid to mental health and antidepressant can alleviate anxiety and depression of the cancer patients'at or around the time of radiotherapy.

Hot-melt extrusion was applied to prepare mesoporous silica/ethylcellulose mini-matrix for sustained release, and fenofibrate was used as a model drug, ethylcellulose and xanthan gum were chosen as sustained-release agent and releasing moderator, respectively. This novel matrix obtained the controlled release ability by combining mesoporous silica drug delivery system and hot-melt extrusion technology. And mesoporous silica particle (SBA-15) was chosen as drug carrier to increase the dissolution rate of fenofibrate in this martix. Scanning electron microscope, transmission electron microscope, small angle X-ray powder diffraction and N2 adsorption-desorption were introduced to determine the particle morphology, particle size and pore structure of the synthesized SBA-15. The results showed that SBA-15 had a very high Brunauer-Emmett-Teller specific surface area, a narrow pore size distribution, large pore volume and a ordered two-dimensional hexagonal structure of p6mm symmetry. Differential scanning calorimetry and X-ray powder diffraction results demonstrated that fenofibrate dispersed in an amorphous state inside the pores of the mesoporous silica which contributed to the improvement in the dissolution rate. The drug release of mini-matrices was influenced by ethylcellulose viscosity grades and xanthan gum concentration, which increased with the increasing of xanthan gum concentration and decreasing of ethylcellulose viscosity. Mini-matrix containing 22% xanthan gum exhibited a good sustained release performance, and the drug release behavior followed the first-order kinetics.

Objective To investigate the genetic characteristic of whole-genome of influenza A/H3N2 viruses in severe acute respiratory infection cases in Beijing area.Methods From 2014 to 2016,the viral RNA was extracted from 32 strains isolated from SARI cases,then sequenced by Ion Torrent PGM Sequencer.The phylogeny and molecular features of whole-genome were analyzed by Mega and Consurf software.Results The HA gene of tested strains isolated in 2014-2015 influenza season belonged to lineage 3C.3a and 3C.2a,while those isolated in 2015-2016 influenza season belonged to cluster 3C.2a.Moreover,compared with the vaccine strains,7 variant amino acids of protein of HA1 were identified,and two of them were located in antigenic sites.All isolates were sensitive to neuraminidase inhibitors while showed resistance to blockers for M2 ion channel.Conclusion The phylogenetic features of isolates studied in this study are similar with that of current circulating strains.However,the difference between isolates and vaccines should not be overlooked.
