Objective To explore the effect of Shenshuaining capsule on nutritional status and blood rheology in patients with chronic renal failure.Methods 150 cases of chronic renal failure were randomly selected and were randomly divided into observation group and control group, 75 cases in each group.The control group were given hemodialysis for treatment,and the observation group was treated with Shenshuaining capsule one week after dialysis.The clinical effect,nutritional status and biochemical indicators in the two groups were observed.Results The total effective rate in the observation group was 86.67%, which was higher than 72.00% in the control group,the difference was statistically significant(x2=4.920,P<0.05).After treatment,the nutrition indicators of HBG,ALB,IgG,IgA and IgM in the observation group were (135.7±16.4)g/L,(34.5±2.9)g/L,(10.8±0.7)g/L,(2.1±0.4)g/L and (1.7±0.3)g/L respectively, which were higher than those in the control group[(113.8±16.9)g/L,(28.4±2.5)g/L,(7.6±0.8)g/L,(1.3±0.3)g/L and (1.2±0.2)g/L], the differences were statistically significant(t=8.054,13.797,26.070,13.856,12.010,all P<0.01).In the observation group,the incidence rate of undernutrition was 25.33%, which was lower than 46.67% in the control group, the difference was statistically significant(x2=45.905,P<0.05).After treatment,the blood urea nitrogen and blood urea in the observation group were (349±64)μmol/L and (10.4±3.7)mmol/L respectively,which were lower than those in the control group[(462±51)mol/L and (14.2±4.5)mmol/L], the differences were statistically significant(t=11.958,5.649,all P<0.05).After treatment,the creatinine clearance rate and concentration of hemoglobin in the observation group were (25.1±6.1)mL/min and (92.1±21.1)g/L respectively, which were higher than those in the control group[(21.7±5.4)mL/min and (84.7±15.3)g/L], the differences were statistically significant(t=3.614,2.459,all P<0.01).After treatment, the high blood viscosity,low blood viscosity,plasma viscosity and hematocrit in the observation group were (3.59±0.94)m/Pas,(7.84±0.97)mPa/s,(1.31±0.15)mPa/s and (0.33±0.07) respectively, which were lower than those in the control group[(4.41±1.13)mPa/s,(8.72±1.05)mPa/s,(1.43±0.24)mPa/s and (0.42±0.05)], the differences were statistically significant(t=11.958,5.649,2.459,all P<0.01).Conclusion For patients with chronic renal failure,Shenshuaining capsule combined with hemodialysis can improve the nutritional status and blood rheology.

Objective To explore the matrix effect on cyclosporine A (CsA) test by fluorescence polarization immunoassay (FPIA) and enzyme-multiplied immunoassay technique (EMIT), explain the discrepancy of external quality control results between these two methods and find the corrective action.Methods One hundred whole blood samples with various concentrations were adopted and CsA levels were detected by FPIA and EMIT.The results were compared with each other.Moreover, the influence of residual metal ions upon immunoreactions was assessed by adding Cu2+ and Zn2+.The effect of non-whole blood matrix on extraction efficiency for quality control materials and CsA calibrator was evaluated by adding identical volume of Hb-rich reagents followed with re-extraction.Results There is good correlation between results measured with FPIA(X) and EMIT(Y) methods ( Y=0.926 8X -8.115,R2 =0.996 9).Neither FPIA nor EMIT was affected by residual metal ions ( P ＞ 0.05 ). Non-whole blood matrix decreased the extraction efficiency of two methods, but it could be corrected by supplementation of the Hb-rich reagents (≥30 g/L).Conclusions Non-whole blood matrix may be the main reason for the inconsistent results measured by FPIA and EMIT methods.It could be corrected by using Hb-rich reagents.In addition,we should consider the influence of low lib on CsA test,espocially for organ transplant patients with lower Hb ( ＜30 g/L).

Objective To investigate balanced steady-state free precession with flow-sensitive dephasing magnetization preparation (FSD-bSSFP) in the assessment of arteries of foot in diabetic patients.Methods The lower-extremity peripheral arteries of 43 diabetic patients were evaluated by FSD-bSSFP no contrast MRA and contrast-enhanced MRA (CE-MRA)in. Two experienced observers assessed the image quality, degree of venous contaminated and visibility of pedal artery branches by FSD-bSSFP and CE-MRA respectively in consensus. The signal intensity( SI), signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the source images of both groups were measured and Wilcoxon and t tests were performed. Results The image score of FSD-bSSFP group was 2.7 ± 1.1 and CE-MRA was 2.6 ± 0.8, there was no statistical difference ( Z = 0. 134, P ＞ 0. 05 ). The image score of demonstration of the pedal artery branches and degree of venous contamination on FSD-bSSFP were 3.2 ± 0. 9 and 1.8 ± 0. 4 respectively which were superior to that of CE-MRA (2.5 ± 0.9 and 2.1 ± 0.8 respectively). Significant statistical difference existed between the two groups in demonstration of pedal artery branches ( Z = 5.246, P ＜ 0.05 ) and degree of venous contamination (Z =2.541 ,P ＜0.05). SNR of FSD-bSSFP was 148.6 ±26.7, CNR was 88.3 ± 19.0. SNR of CE-MRA was 148.5 ± 45.6, CNR was 121.0 ± 41.0. No statistical difference existed between SNR between two methods (t = 0.013, P ＞ 0.05 ). But CNR of CE-MRA was superior to that of FSD-bSSFP and significant statistical difference existed between these two methods ( t = 5.113, P ＜ 0.01 ). Conclusion FSD-bSSFP without contrast could be used in the evaluation of foot arteries in patients of renal dysfunction and diabetes.

Objective To investigate the biological function of M122 in pathogenesis of MCMV in developmental brain disorders and brain damage, screening for mouse brain cDNA library interacting with M122 was performed by a yeast two-hybrid system. Methods The reconstructed bait plasmid pGBKT7-M122 was transformed into yeast cells AH109 and screened on the nutrient deficiency medium SD/-Trp. After express of the bait protein in AH109 yeast strains was detected by Western blot analysis, yeast-two hybrid screening was performed by mating AH109 with Y187 containing mouse brain cDNA library plasmid. The diploid yeast cells were plated on the nutrient deficiency medium SD/-Trp/-Leu/-His/-Ade. The second screening was performed with SD/-Trp/-Leu/-His/-Ade containing X-α-gal. The plasmids in positive colonies were extracted and transformed into E. coli JM109 cells. After plasmid DNA in JM109 cells were extracted form positive colonies and sequenced, the results were analyzed by bioinformatic methods. The interactions between M122 protein and the protein obtained from positive colonies were further confirmed by repeating yeast-two hybrid. Then, autoactivations of the proteins obtained from positive colonies were detected.Results The reconstructed bait plasmid was transformed into yeast cells AH109 successfully. The bait protein expressed in the yeast cells AH109 stably. 24 proteins interacting with MCMV M122 were screened, including syntaxin 8 ( Stx8 ), phosphoglucomutase 2 ( Pgm2 ), potassium voltage-gated channel, shaker-related subfamily, beta member 1 ( Kcnab1 ), collagen, type ⅪⅩ, alpha 1 ( Col19a1 ), archain 1 ( Arcn1 ), cytidylate kinase( Cmpk), DnaJ(Hsp40) homolog, subfamily A, member 1 (Dnaja1), ATPase, Na+/K + transporting, beta 3 polypeptide( Atp1b3 ), SH3-domain GRB2-like ( endophilin ) interacting protein 1 ( Sgip1 ),ankyrin repeat domain 17 (Ankrd17), Smg-7 homolog, nonsense mediated mRNA decay factor(Smg7),sperm associated antigen 9 ( Spag9 ), FK506 binding protein 1a ( Fkbp1a), MYST histone acetyltransferase monocytic leukemia 4 ( Myst4), hyaluronan and proteoglycan link protein 1 ( Hapln1), autophagy-related 3 (Atg3), splicing factor, arginine/serine-rich 5 ( Sfrs5 ), zinc finger, C3HC-type containing 1 ( Zc3hc1 ),thioredoxin-related transmembrane protein 1 ( Txndc1 ), adaptor protein complex AP-1, gamma 1 subunit (Ap1g1), Cullin 1 ( Cul1 ), and so on. Three of them were formerly unknown proteins. M122 protein could interact with the proteins obtained from positive colonies in the yeast cells AH109. Ap1g1 and Cul1 were proved to have autoactivation. Conclusion A class of proteins in brain interacting with M122 has been obtained. It is presumed that these proteins are correlated with neuropathogenesis of the brain disorders caused by CMV, but the candidates still need further confirmation for the interaction.

Aim To explore the effect of receptor component protein(RCP)in the signal transduction of vascular smooth muscle cell(VSMC)proliferation induced by static pressure.Methods The mouse-derived vascular smooth muscle cell line(A10VSMC)was employed in the experiment.Cells were exposed to static pressure,and MTT assay was used to detect the cell viability.Western blot was used to determine the expressions of PCNA,RCP and p-Akt,RCP mRNA was tested by RT-PCR,and co-immunoprecipitation was used to test the interaction between RCP and G proteins.Results The cell viability,expressions of PCNA and RCP increased with the elevation of static pressure and reached their peaks at 120 mmHg,and after 6 hours they got a plateau.The static pressure significantly increased the level of p-Akt,meanwhile,the binding of RCP and Gαs significantly decreased.However,the binding of RCP and Gβ increased in response to static pressure after stimuli of static pressure,but Gγ was obscure.Conclusion Static pressure can induce VSMC proliferation and expression of RCP,which may involve G protein signal transduction model.
