目的 研究乌司他丁对重症急性胰腺炎(SAP)患者血清TNF-α、IL-6、IL-10水平的影响。方法 对2010年1 月至
2014年1月收治的160例SAP 患者,按随机数字表法分为对照组和治疗组,每组80例。观察两组患者治疗前后血清TNF-α、IL-6、IL-10 水平变化及临床疗效。结果 治疗前两组患者血清TNF-α、IL-6、IL-10 水平比较,差异均无统计学意义(均P>0.05)。治疗7d 后两组患者血清TNF-α、IL-6 水平均较治疗前显著降低(均P<0.01),并且治疗组下降更明显(均P<0.01);血清IL-10水平均较治疗前显著上升(均P<0.01),并且治疗组上升更明显(均P<0.01)。对照组治疗总有效率73.75%,治疗组总有效率86.25%,两组比较差异有统计学意义(P<0.05)。结论 乌司他丁对SAP 治疗有效,能有效调控患者机体的炎症反应,阻断炎症进程,加速患者康复。 相似文献

Spallation neutrons were produced by the irradiation of Pb with 250 MeV protons. The Pb target was surrounded by water which was used to slow down the emitted neutrons. The moderated neutrons in the water bath were measured by using the resonance detectors of Au, Mn and In with a cadmium (Cd) cover. According to the measured activities of the foils, the neutron flux at different resonance energies were deduced and the epithermal neutron spectra were proposed. Corresponding results calculated with the Monte Carlo code MCNPX were compared with the experimental data to check the validity of the code. The comparison showed that the simulation could give a good prediction for the neutron spectra above 50 eV, while the finite thickness of the foils greatly effected the experimental data in low energy. It was also found that the resonance detectors themselves had great impact on the simulated energy spectra. 相似文献
