Objective To investigate the blood pressure circadian rhythm in patients with IgA nephropathy by ambulatory blood pressure monitoring and explore its role in the disease progression. Methods A cross sectional study was carried out.Blood pressure rhythm was studied by ambulatory 24-hour monitoring with a portable oscillometric recorder in selected patients with primary IgA nephropathy.The term dipper was described as blood pressure during night dropped at least 10％ below daytime blood pressure.The term non-dipper referred to those in whom the nocturnal decline in blood pressure was less than 10％.Clinicopathological indices between dipper and non-dipper groups were compared. Results Ninety-three patients completed ambulatory blood pressure monitoring among whom 68 (73％) patients were non-dipper.The frequency of non-dipper was 70％,70％ and 81％ in the patients at chronic kidney disease stage 1,2 and 3 or more.The frequency did not differ among these three group patients (P=-0.587).77％ of patients with hypertension and 69％ of patients with normotension were non-dipper (P=0.373).The disappearance of blood pressure circadian rhythm in IgA nephropathy was not influenced by age,gender,blood pressure,proteinuria,renal function and renal pathology lesions.Among the patients who were followed up regularly for more than 12 months (n=54),patients in the dipper group had a trend of slower eGFR decline rate than those in non-dipper group albeit the difference was not significant (P=0.329).Subgroup analysis revealed that in patients with hypertension and non-dipper (n=29),the eGFR decline rate was much faster than that in dipper group[(-6.79±11.58 )vs (-0.34±1.74) ml ·min-1 ·(1.73 m2)-1·year-1,P=0.019]. Conclusions Most patients with IgA nephropathy present disappearance of blood pressure circadian rhythm,even among those at an early stage or without hypertension.The loss of blood pressure rhythm may be associated with a rapid renal function decline rate in those with hypertension.

Objective To study the antitumor effect and mechanism of co-cultured cytokine-induced killer(CIK) cells and autologous DC modified with IL-24 gene on A549 cells in vitro. Methods DC and CIK cells were prepared routinely from human peripheral blood mononuclear cells(PBMC). Recombinant adenovirus vector pAdEasy-1-pTrack-CMV-IL-24 was extracted from DH5α, it was lineared with Pac I and transfected into A293 cells, and then the IL-24 recombined adenovirus(Ad-IL-24) was obtained. Ad-IL-24 was used to infect DC. The cells obtained were named DC-IL-24. RT-PCR and ELISA were used to evaluate the expression of IL-24 gene in transfected DC. The phenotypes change of DC were identified by flow cytometry analysis, the concen-tration of IL-12 and TNF-α in supernatant of DC were determined by EIJSA. The ability of CIK producing per-forin was measured by homolysis method. FCM was used to determine the cytotoxicity of cocultured CIK cells and autologous DC modified with IL-24 gene to A549 cells. Results We obtained the high titre of Ad-IL-24.IL-24 gene was transfered into DC successfully via Ad-IL-24. The green fluorescence was observed on DC by fluorescence microscope. The expression rate of CD80, CD83, HI.A-DR, CD40, CXCR4 on DC-IL-24 was sig-nificantly increased compared with that of the control group. DC-IL-24 produced markedly higher levels of IL-12 and TNF-α as compared with DC. DC-IL-24 can enhance the ability of CIK cells producing perforin. On com-parison with non-transfected DC co-cultured with CIK cells, transfected DC co-cultured with CIK cells had a sig-nificantly higher lytic activity against A549 cells. Conclusion IL-24 gene modification can enhance the anti-tu-moral immunity of DC. The mechanism of which might be related to the increased secretion of IL-12 and TNF-α, up-regulation expression of co-stimulatory molecules and MHC Ⅱ class molecules on DC, promoting the acti-vation and maturation of DC, and then enhancing CIK cells to generate specific anti-tumoral immunity.

Objective:To study the antitumor effect and mechanism of cocultured CIK cells modified with IL-24 gene and autologous DCs on HL-60 cells in vitro.Methods:DCs and CIK cells were prepared routinely from human peripheral blood mononuclear cells ( PBMC).IL-24 gene was transferred into CIK cells via electroporation.The cells obtained were named CIK-IL24.RT-PCR and ELISA were used to evaluate expression of IL-24 gene in transfected CIK cells.The phenotypic changes of CIK cells were identified by flowcytometry analysis.The concentration of IFN-γ and TNF-α in supernatant of CIK was determined by ELISA.FCM was used to determine the cytotoxicity of cocultured CIK cells modified with IL-24 gene and autologous DCs against HL-60 cells.Results:Eukaryotic expressing plasmid pcDNA3.0-IL24 was transferred into CIK cells successfully via electroporation.The expressing rate of CD3~+、CD3~+CD56~+ cells had no significant change in CIK cells.However,the rate of CD4~+CD25~+ cells was significantly decreased compared with that of the control group.Expression of adhesion molecules CD54,CXCR4 were significantly increased on CD3+CD56+ cells.CIK-IL24 cells produced markedly higher levels of IFN-γ and TNF-α as compared with the CIK cells.By comparison with non-transfected CIK cells co-cultured with DCs,transfected CIK cells co-cultured with DCs had a significantly higher lytic activity against HL-60 cells.Conclusion:IL-24 gene modification can enhance the anti-tumoral immunity of CIK cells,the mechanism of which might be related to the increased secretion of IFN-γ,TNF-α,up-regulation of adhesion molecule expression,and reduction of the rate of CD4~+CD25~+ cells in CIK cells.
