The biological incompatibility of traditional peritoneal dialysis fluids(PDF) is the main reason for the poor outcomes of long-term peritoneal dialysis and the high rate of technical failure.Recently,two-compartment PDF has been applied in the treatment of peritoneal dialysis patients,and reportedly has lots of clinical advantages due to its better biocompatibility.This paper presents an overview of recent advances in the studies of two-compartment PDF.

Objective:A novel tuberculosis DNA vaccine integrating siRNA,fusional antigen and hIL-12 triple expression units was constructed in our laboratory.Methods:To evaluate the independent expression of the three expression units,two eukaryotic expression plasmid pVAX1-siRNA-PVAE[EGFP]-hIL12 with TB fusional gene Ag85B-ESAT6(PVAE) and enhanced green fluorescent protein(EGFP),and pVAX1-siEGFP-PVAE[EGFP]-hIL12 with siRNA coding sequence targeting EGFP instead of Mcl-1L were constructed.Then two plasmids were used to transfer human embryonic kidney 293 cells.Based on EGFP report gene,it was demonstrated that siRNA expression unit and fusional antigen gene were independently expressed.Results:The hIL12 expression at 48h and 72h post transfection were also detected by ELISA analysis up to 1571.63pg/ml and 2392.25pg/ml respectively in the cell culture fluid.Conclusion:The results demonstrated that the novel DNA vaccine with siRNA,TB fusional antigen and hIL12 three expression units in the same plasmid frame is successfully constructed and independently expressed in eukaryotic cells.It laid a foundation for further animal model study on anti-tuberculosis effects of this novel DNA vaccine.

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

Objective To investigate the distribution of HLA-B27 subtypes in ankylosing spondylitis(AS) patients of Chinese Han population by using the updated HLA-B27 typing data. Methods One hundred AS subjects were randomly selected from spondyloarthritis patients data bank of the third affiliated hospital of Sun Yat-sen university. All subjects were independent individuals, and the duplicated samples in the same family were excluded. Salt fraction method was used to prepare genome DNA. Luminex liquid array combining PCR-SSOP was used to perform the low resolution HLA-B genotyping. PCR-SSP was applied to perform the high resolution HLA-B27 typing for HLA-B27 positive subjects. Results Ninety-eight independent AS patients were recruited randomily, of which, 93 were HLA-B27 positive, with positive rate 94.9%, and covered 96% patients with family history of AS. Three subtypes were detected in this population including B * 2704 (n=76, 81.7%), B * 2705 (n=12, 12.9%) and B * 2715 (n=5, 5.4%). Compared with the two reports about HLA-B27 subtype distribution in healthy HLA-B27 positive Han population there was no significant difference between AS patients and healthy controls. But no B * 2715 case was found in those two reports of healthy population. Three reports (including 1 report in Chinese) could found about B * 2715 subtype, but all positive cases were oriental people. Furthermore, all B * 2715 positive patients were AS patients. Conclusion B * 2704 is the predominant subtype ,in AS patients of Chinese Han population, and followed by B * 2705. We found five cases with positive B * 2715, a considerable rare allele. This may suggest association between B * 2715 and AS.

Age - related macular degeneration ( AMD ) is the leading cause of irreversible visual loss in elderly people among white - dominated population. At percent, treatment for AMD includes anti - vascular endothelial growth factor antibody ( Anti- VEGF ) drug treatment, photodynamic therapy ( PDT ) , topical application of triamcinolone acetonide ( TA ) and laser therapy ( nanosecond laser) etc. Through comparative analysis of different treatment methods of AMD, we review the mechanism, clinical efficacy, adverse events and cost effectiveness to provide the basis for clinical treatment.

OBJECTIVE:To study on the phlorotannins in Ecklonia kurome. METHODS:Silica gel column chromatography and Sephadex LH-20 column chromatography were conducted for isolation and identification of phlorotannins,and the compound structures were analyzed and identified based on physicochemical properties and spectral data. RESULTS:Totally 7 phlorotannins were isolated from E. kurome,namely Phloroglucinol(1),Eckol(2),Fucodiphloroethol G(3),Phlorofucofuroeckol A(4),1-(3′, 5′-dihydro-xyphenoxy)-7-(2″,4″,6-trihydro-xyphenoxy)-2,4,9-trihydroxydibenzo-1,4-dioxin(5),Dieckol(6)and 6,6′-bieckol (7). CONCLUSIONS:Compound 5 and 7 are isolated from E. kurome for the first time,and the study has laid a foundation for its quality evaluation.

Objective To investigate the knowledge and attitude of nurses on prevention and intervention of common complications among bedridden patients in Chinese hospitals and to explore the influential factors.Methods It was a cross-sectional study.A total of 3 903 nurses from 6 tertiary hospitals,11 secondary hospitals and 8 primary hospitals from 6 provinces and cities were recruited by convenience sampling and surveyed using selfdesigned questionnaires.Results Nurses' average scoring rate of knowledge and attitude were 73.46％ and 85.02％.Level of hospitals,whether in ICU or not,age,working time,educational background,job title,position,employment form were influential factors for nurses' knowledge (P＜0.05).Meanwhile,level of hospitals,educational background,position,employment form were influential factors for nurses' attitude (P＜0.05).Conclusion Nurses took a positive attitude for prevention and intervention of common complications among bedridden patients,while the level of nurses' knowledge should be improved.

Quality management of scientific research is a systematic work,quality control of multicenter nursing research depends on perfect and effective quality management system,measures and procedures,as well as rigorous scientific attitude in project team. To establish and improve quality management system of scientific research,to for-mulate standard quality control procedures,to promote the usage of electronic data acquisition system in multicenter nursing researches,and to improve scientific,standard,and refined quality management of research are effective mea-sures to guarantee quality control of multicenter nursing research. This paper summarized quality control methods for multicenter investigation,to provide more experience for nursing researchers as references.
