Objective To investigate the actual cost and benefit of stoma nursing at present as a reference for the improvement of stoma care cost management program. Methods A cross sectional study was carried out in gastrointestinal surgery of a tertiary- level hospital in southwestern China from April 2014 to December 2014. The consumption of intestinal stoma care work, the average monthly income/average monthly working hours ratio and other indicators of stoma care nurse specialist were measured by the step cost allocation method, to investigate the actually cost of a single stoma care service which colostomy patients had received and analyze the gap between actually costs and charge standard of Sichuan Province. Results The directly human cost of stoma care expenses were (22.33 ± 3.66) yuan; working fee expenses were (4.18 ± 0.68) yuan;administrative expenses were (1.87 ± 1.32 ) yuan; research and education expenses were (1.87 ± 1.32 ) yuan; the total cost of investment was (29.14 ± 4.76) yuan, which was much higher than the current charge standard of Chengdu Bureau of Commodity Prices (t=119.50, P <0.05). Conclusions There is a difference between the actual cost and charge standard of stoma care. The situation of low pay to labor is not in line with economic laws, and not conducive to the future development of stoma care speciality.

Objective To explore the effect of IFN-γ, IL-10 and IL-4 on B cell activating factor (BAFF) expression in human HL-60 cells, a kind of myeloid tumor cell lines, and its possible regulation mechanism. Methods Cultured human HL-60 cells were treated with IFN-γ, IL-10 and IL-4 for 1-3 days. The expression of membrane-bound BAFF on HL-60 cells was examined by flow cytometry, the amount of soluble BAFF was detected by ELISA assay, and the level of BAFF mRNA was tested by real-time PCR method. A functional 1021 bp fragment of the 5'-tlanking region of the human BAFF gene (-1349 to -329 bp) was cloned and investigated with serial 5'-deletion. The 5'-deleted promoters were recombinated with chloramphenicol acetyltransferase (CAT) as reporter gene. These five recombinant plasmids were transiently transfected to HL-60 cells with liposomal transfectian method. Promoters activities were determined by CAT reporter gene assay(CAT-ELISA) in those transfected cells treated with different cytokines. Results The results showed that the expression of membrane-bound BAFF, soluble BAFF and BAFF mRNA in human HL-60 cells were significantly elevated (P ＜ 0. 05) after incubated with IFN-γ and IL-10. In addition, IFN-γ and IL-10 showed significantly (P ＜ 0. 05) increased effects on promoter activity in human BAFF gane. And the cytokines-responsive sequences were located between -929 and -719 bp of the BAFF promoter region. Conclusion The enhancement of IFN-γ and IL-10 on BAFF expression and synthesis were regnla-ted by promoter activation. Our in vitro studies also raise the possibility to investigate the mechanisms regula-ting BAFF expression in other tumor cells of myeloid origin under pathological circumstances.

Objective To explore the effect of several cytokines, including interferon-γ, interleukin-10 and interlekin-4, on promoter activity of human BAFF (B-cell activating factor belonging to tumor necrosis factor family) gene. Methods A construct of phBAFF 1.02 containing sequence form -1349 bp to -329 bp of human BAFF gene, linking with chloramphenicol acetyltransferase (CAT) as reporter gene, was transiently transfected into human HL-60 cells, a kind of myeloid tumor cell lines. The cells were subsequently treated with IFN-γ, IL-10 and IL-4, and the CAT activity was assessed 24 hours after stimulation with each cytokines. Results IFN-γ of 5 ng/ml, IL-10 of 100 ng/ml could increase the CAT activity of phBAFF 1.02 to 4.18 and 2.13 folds respectively compared to the control. IL-4 at 100 ng/ml had no effect on promoter activity of human BAFF gene. Combination of IFN-γ, IL-10 and IL-4 could increase the CAT activity of phBAFF 1.02 to 3.41 and 1.58 folds respectively compared with controls. Conclusion IFN-γ and IL-10 can increase the promoter activity of human BAFF gene. IL-4 treatment can not affect the CAT activity driven by BAFF promoter. However, IL-4 can decrease the upregulating effect of IFN-γ and IL-10 on phBAFF1.02. These provide essential evidence for future study on the interaction mechanism of cytokines and BAFF in autoimmune diseases.

The effects of over-expression of ANXA10 gene on proliferation and apoptosis of hepato-cellular carcinoma cell line HepG2 were elucidated. The human ANXA10 gene was subcloned into the lentiviral vector, PGC-FU, to generate the lentiviral expression vector, PGC-FU-ANXA10. The corrected ANXA10 was confirmed by endoenzyme digestion, and sequencing. Recombinant lentiviruses were produced by 293T cells following the co-transfection of PGC-FU-ANXA10 with the packaging plasmids pHelper1.0 and pHelper2.0. The resulting recombinant lentiviruses carrying ANXA10 were then used to infect human embryonic kidney epithelial cells, and lentiviral particles were produced. The ANXA10 expression in 293T cells was detected by using fluorescent microscope and Western blotting. HepG2 cells were infected, and divided into PGC-Fu-ANXA10 group, PGC-Fu group and HepG2 cell group. The changes of ANXA10 mRNA and protein expression were detected by using RT-PCR and Western blotting respectively. Flow cytometry and MTT assay were performed to examine the changes in cell apoptosis and proliferation respectively. The recombinant PGC-FU-ANXA10 vector was successfully constructed, the ANXA10 protein was detected by using Western blotting, and virus titer was 2×10(8) TU/mL. The recombinant lentiviruses were effectively infected into HepG2 cells in vitro and the infection efficiency was 70%. At 72 h after infection, the ANXA10 mRNA and protein expression levels in PGC-Fu-ANXA10 group were significantly higher than in PGC-Fu group and HepG2 cell group (P<0.05); the in vitro growth inhibition rate of HepG2 cells in PGC-Fu-ANXA10 group was 24.65%, significantly higher than that in PGC-Fu group and HepG2 cell group (P<0.05), but there was no significant difference between PGC-Fu group and HepG2 cell group; the apoptosis rate in PGC-Fu-ANXA10 group, PGC-Fu group and HepG2 cell group was (51.92±1.41)%, (19.00±1.12)% and (3.59±0.89)% respectively. The apoptosis rate in PGC-Fu-ANXA10 group was significantly higher than in PGC-Fu group and HepG2 cell group (P<0.05). The recombinant lentiviruses PGC-FU-ANXA10 were constructed successfully and infected into HepG2 cells. The overexpression of ANXA10 gene can significantly inhibit proliferation and promote apoptosis of HepG2 cells in vitro.

Objective: To investigate the association between estimated glomerular filtration rate (eGFR) and all-cause mortality in the elderly aged 65 years and older in longevity areas in China. Methods: Data used in this study were obtained from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey, 1 802 elderly adults were collected in the study during 2012-2017/2018. In this study, the elderly were classified into 4 groups, moderate-to-severe group [<45 ml·min^-1·(1.73 m²)^-1], mild-to-moderate group [45- ml·min^-1·(1.73 m²)^-1], mild group [60- ml·min^-1·(1.73 m²)^-1] and normal group [≥90 ml·min^-1·(1.73 m²)^-1] according to their eGFR levels. Results: After 6 years of follow-up, 852 participants died, with a mortality rate of 47.3%. Multivariate Cox regression analysis showed that the levels of eGFR were negatively correlated with all-cause mortality risk in the elderly (the HR of elderly was 0.993 and the 95%CI was 0.989-0.997 for every unit of eGFR increased, P=0.001), while compared with the group with normal eGFR, the HRs (95%CI) of the elderly in the moderate-to-severe group, mild-to-moderate group, and mild group were 1.690 (1.224-2.332, P=0.001), 1.312 (0.978-1.758, P=0.070), 1.349 (1.047-1.737, P=0.020) respectively [trend test P<0.001]. Conclusion The decrease in eGFR was associated with higher mortality risk among the elderly in longevity areas in China.
