ABSTRACT
Objective To investigate and evaluate the effects and safety of the operationabsorption of irrigation fluid occurs during 1470 nm diode laser vaporization of the prostate by ethano. Methods We retrospectively analyzed the clinical data about 32 cases of BPH treated by 1470 nm diode laser vaporization from May 2016 to December 2016 intraoperative use of isotonic saline contains 1.0％ ethanol as perfusion fluid, monitor the patients' breath ethanol concentration, calculation of perfusion fluid absorption. Results All the operations were successfully completed, the average operation time was (57.6 ± 32.9) min, the average perfusion fluid volume was (21.5 ± 9.9) L, only 5 cases detected perfusion fluid absorption, the average absorptive amount was (156.8 ± 111.7) ml. During operation, all the patients with stable breathing, circulation, no alcohol poisoning symptoms, no bleeding, capsular perforation, cardiorespiratory failure occurred. All the 32 cases patients were followed up for 3 months, which revealed a significant improvement in dysuresia, no severe complications such as urethrostenosis, urinary incontinence, secondary hemorrhage were noted. Conclusion Fluid absorption little occurs during 1470 nm diode laser vaporization, it is safe and effective in treatment of benign prostatic hyperplasia.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate serum IL-18 levels in mice with collagen-induced arthritis treated by recombinant adenoviral vector containing mIL-18BP and mIL-4 fusion gene (AdmIL-18BP/mIL-4).</p><p><b>METHODS</b>Arthritis was induced by injection of collagen in male DBA-1/BOM mice. Mice with collagen-induced arthritis (CIA) were intra-articularly injected with 10(7)pfu/6μL of AdmIL-18BP/mIL-4; and in mice of control groups AdLacZ or PBS were used. The animals were sacrificed at week 1, 2 and 4 after treatment. Serum IL-18 levels were determined by ELISA at the different time points.</p><p><b>RESULT</b>The mean serum levels of IL-18 at weeks 1, 2, and 4 after injection of AdmIL-18BP/mIL-4 were (36.5±5.4)ng/L, (32.5 ± 3.2) ng/L and (28.7 ±2.9)ng/L, respectively, which were significantly lower than those at the same time point of AdLacZ group [(66.2 ±5.1)ng/L, (69.2 ±4.2)ng/L and (77.7 ±3.9)ng/L] and PBS group [(67.3 ±7.1)ng/L, (71.9 ±1.8)ng/L and (78.7±4.1)ng/L] (P<0.01 at all time points). In the therapy group, there were no significant differences in the mean serum concentrations of IL-18 at all time points.</p><p><b>CONCLUSION</b>The serum IL-18 levels in CIA mice are down-regulated by treatment of recombinant adenovirus containing mIL-18BP and mIL-4 fuse gene, which might be a promising therapeutic strategy for rheumatoid arthritis.</p>
