Objective To explore the correlation between cytomegalovirus pneumonia (CMV-IP) and viral load in renal transplant recipients and to find out the threshold value of viral load for predicting CMV-IP. Methods The blood samples of 56 renal transplant recipients were taken weekly for the first 2 months and every 2 weeks for 2-6 months after transplantation.Real-time PCR were used to quantify the plasma CMV DNA.The mean viral loads of CMV-IP group and non-CMV-IP group in each time were compared using Wilcoxon test.Different cut-off values were tested to find the suitable values to predict the CMV-IP. Results Of the 56 recipients,8 (14.3%) developed CMV-IP.The viral loads were near zero in the first 4 weeks in both groups;from week 5 the viral load of CMV-IP group increased gradually and reached the climax at week 8 and then declined,but the load of non-CMV-IP group fluctuated at a low level.During weeks 5-11,the viral loads of CMV-IP group were higher than those of non-VMV-IP group.At 5,7 and 9 weeks,the differences of the viral loads between the 2 groups were significant (P

Objective To explore the application of diffusion tensor imaging in the assessment of ischemic muscle in hind-limb ischemia model of rabbit. Methods Excision of femoral artery in unilateral hind limb was done in 14 New Zealand white rabbits and ischemic model were established in 12 rabbits. Three (12 rabbits),10(10 rabbits) ,28(7 rabbits),56(5 rabbits) days after the model establishment, DTI scan was performed on bilateral hind limbs in each of the models, respectively and, λ_1,λ_2,λ_3, ADC and FA values were measured. Histological analysis was also performed at these time points. Pared t test was used to compare the differences of these indexes in bilateral hind limbs. Results Following femoral artery excision, a rapid ascending of ADC,λ_2,λ_3 values with sharply reduced FA value was observed in ligated hind-limb, which reached maximal on 3 days post-excision (ADC_(ligated)= 1.72±0.16, ADC_(unligated)= 1.53±0.16, t = 6.48, P < 0.01 ; λ_(2 ligated)= 1.70±0.15, λ_(2 unligated)= 1.51±0.06, t=10.87, P < 0.01 ; λ_(3 ligated_ =1.17±0.12, λ_(3 unligated)= 0.88±0.12, t=6.67, P < 0.01 ; FA_(ligated)= 0.24±0.04, FA_(unligated) =0.39±0.03, t = -10.61 ,P <0.01) and histologic analysis revealed the severest muscle damag at that time. Ischemic muscle recovered very slowly during the first 10 day post-excision accompanied with reduction of ADC , λ_2, λ_3 values, however there was also difference of ADC,λ_2, λ_3 values between ligated and nonligated limbs except λ_1 ( ADC_(ligated) = 1.65±0. 16, ADC_(unligated)= 1.50±0.12, t =6.42, P <0.01 ; λ_(2 ligated) = 1.62±0.32, λ_(2 unligated) =1.48±0.31, t=5.09, P < 0.01) ; λ_(3 ligated)= 1.11±0.13, λ_(3 unligated)= 0.85±0.09, t=6.26, P <0. 01;λ_(1 ligated)=2.20±0.21, λ_(1 unligated) =2.18+0.20, t=0.87, P=0.40). After 28 days, ADC and λ_3 returned to normal (ADC_(ligated)= 1.51±0. 16, ADC_(unligated)= 1.55±0.14, t=-1.35, P=0.23 ; λ_(3 ligated) =0.95±0. 10, λ_(3 unligated)= 0.92±0.06, t=1.70, P=0.14), but λ_2 and FA of ligated limb were still different from those of nonligated limb (λ_(2 ligated)= 1.45±0.23, λ_(2 unligated)= 1.52±0. 95, t=-3.56, P=0.012; FA_(ligated)=0.35±0.02, FA_(unligated)=0.40±0.03, t=-3.83, P<0.01). After 56 days, all parameters retuned to normal(ADC_(ligated) =1.57±0.18, ADC_(unligated)=1.58±0.23, t=-0.71, P=0.52; λ_(1 ligated) =2.18±0.18, λ_(1 unligated)=2.24±0.14, t=-0.22, P=0.10; λ_(2 ligated)=1.64±0.13, λ_(2 unligated)=1.59±0.15, t=0.89, P=0.42; λ_(3 ligated)=0.89±0.1,λ_(3 unligated)=0.91±0.07, t=- 1.64,P= 0.18; FA_(ligated)= 0.39±0. 03, FA_(unligated)= 0.41±0.02, t=-0.83, P=0.47). Conclusion DTI is a quantitative and relatively accurate technique to assess time-dependent changes of ischemic muscle in hindlimb ischemia model of rabbit.

Objective To investigate the effects of CD40-P227A SNP at human B cell signaling and function. Methods Human Ramos B cells were transfected with plasmids of CFP fusion wild type CD40 and mutant type CD40-P227A, together with plasmids of luciferase fusion NF-κB and AP-1, as well as plasmids of GFP fusion NF-κB. Activation of NF-κB and AP-1 pathway were detected by luciferase assay and flow cytometry, degradation of IκBα and nuclear translocation of NF-κB subunits were tested by Western blot and transfactor ELISA assay. Results Compared with wild type CD40, CD40-P227A SNP induced more degradation of IκBα, increased nuclear translocation of p65, p50 and c-Rel. As well as higher activity of NF-κB, as shown by increased NF-κB luciferase and GFP-NF-κB expressing B cells. Moreover, CD40-P227A SNP induced more activation of AP-1 pathway than CD40. CD40-P227A enhanced B cells function by inducing more excretion of IL-6 and TNF-α. Conclusion Our data indicate that CD40-P227A is a gain-of-function phenotype which induces activation of NF-κB and AP-1 signaling pathways and may contribute to the pathogenesis of the SLE autoimmune disease.
