RESUMO
Objective:To investigate the relationship between caspase recruitment domain protein 9 (CARD9) level and inflammatory response in cerebral tissue of ischemic brain injury mice.Methods:Totally 24 SPF BALB/c male mice were randomly(random number) divided into 4 groups: sham operated group, ischemia 3 h group, ischemia 6 h group, and ischemia 12 h group, 6 mice in each group. The permanant middle cerebral artery occlusion (pMCAO) model in the ischemia groups was established by using line embolism to block blood flow. Mice in each group were sacrificed at the predetermined time point after operation. CARD9 and p-p65NF-κB levels were detected by Western blot, and the inflammatory factors mRNA and protein including TNF-ɑ, IL-lβ and IL-6 were detected by RT-PCR and ELISA, respectively. The data were analyzed by SPSS 21.0 software, the comparison of measurement data between each two groups was analyzed by independent sample t test, and the correlations between CARD9 and inflammatory factors were analyzed by Pearson analysis. Results:Compared with the sham operated group, the CARD9 levels in the ischemia 3 h, 6 h and 12 h groups were increased significantly [(0.325±0.011) vs. (0.462±0.019), P=0.036; (0.735±0.036), P=0.003; (0.903±0.024), P=0.001], the p-p65NF-κB levels in the ischemia 3 h, 6 h and 12 h groups were increased significantly [(0.227±0.016) vs. (0.316±0.017), P=0.041; (0.445±0.021), P=0.016; (0.671±0.039), P=0.008], the TNF-ɑ levels in the ischemia 3 h, 6 h and 12 h groups were significantly increased [(0.53±0.06) vs. (1.06±0.10), P=0.009; (1.47±0.15), P=0.004; (2.78±0.18), P=0.001], the IL-lβ levels in the ischemia 3 h, 6 h and 12 h groups were significantly increased [(0.55±0.07) vs. (1.01±0.11), P=0.009; (2.13±0.16), P=0.003; (3.09±0.18), P=0.001], and the IL-6 levels in the ischemia 3 h, 6 h and 12 h groups were significantly increased [(1.99±0.18) vs. (4.10±0.41), P=0.006; (8.54±0.84), P=0.002; (11.56±0.96), P=0.001]. Pearson analysis showed that CARD9 was positively correlated with the p-p65NF-κB and TNF-ɑ, IL-lβ, IL-6 ( r=0.894, P=0.001; r=0.747, P=0.008; r=0.810, P=0.001; r=0.773, P=0.007). Conclusions:A positive correlation exists between CARD9 and inflammatory responses in the early stage of ischemic brain injury in mice
RESUMO
Objective To summarize the clinical experience of ESWL under B ultrasound guidance in treatment of urinary stones.Methods The clinical data of 20 625 patients who underwent B ultrasound-guided ESWL between August 1995 and July 2011 were retrospectively analyzed.Of the stones,8659cases were in the kidney,11 712 cases were in the ureter,and 254 cases were in the bladder.And 1965stones were radioparent.Results The stone fragmentation rates of the kidney,ureter and bladder stones were 96.27％ ( 8336/8659),97.56％ ( 1 1 426/1 1 712) and 99.21％ ( 252/254),respectively.The total stone fragmentation rate was 97.04％ (20 014/20 625 ).The 3-month stone-free rates of the kidney,ureter and bladder stones were 86.63％ (7501/8659),95.32％ ( 11 164/11 712) and 97.24％ (247/254),respectively.The total 3-month stone-free rate was 91.69％ (18 912/20 625).The stone fragmentation rate of radioparent stones was 97.91％ ( 1924/1965 ),and the 3-month stone-free rate was 94.40％ ( 1855/1965).Conclusion B ultrasound-guided ESWL is safe and effective in the treatment of urinary stones.
