Background： Continuous negative pressure drainage （CNPD） is widely used after lower lumbar internal fixation; however, it may cause tremendous blood loss and lead to postoperative hernorrhagic anemia. The present study explored the efficacy and safety of improved intermittent-clamped drainage （ICD） for lower lumbar internal fixation. Methods： This was a prospective study that included 156 patients with decompression of the spinal canal and internal fixation for the first time from January 2012 to December 2014. The patients were randomly divided into ICD group and CNPD group, and each group had 78 cases. A drainage tube was placed under the deep fascia in all patients within 10 min after the commencement of wound closure. The postoperative drainage amount at different time points, the hemoglobin level, and postoperative complications were recorded and compared between the two groups. Shapiro-Wilk test, independent samples t-test, and Mann-Whitney U-test were used in this study. Results： The drainage amount was significantly reduced in the ICD group, as compared with the CNPD group （Z = 10.74, P 〈 0.01 ）. The mean total drainage amount （in rot） of the single-segment and two-segment procedures was significantly greater in the CNPD group than the ICD group （Z =10.63 and 10.75, respectively; P 〈 0.01 ）. For the adverse events, there was no significant difference in postoperative temperature, wound problem, and complications between the two groups. Conclusions： The present study showed a statistically significant reduction in postoperative drainage amount between ICD and CNPD groups, and ICD is an effective, convenient, and safe method for routine use in lower lumbar surgery. It is essential to focus on the effect of clamping drainage with long-segment surgical procedure and complex lumbar disease in the thrther investigation, as well as the effect of clamping on long-term functional outcomes.

为探究碱性环境下急性氨氮胁迫对虹鳟(Oncorhynchus mykiss)抗氧化和免疫功能的影响,研究设置3个不同氨氮处理组(0.86、1.73和2.59 mg/L)对虹鳟进行96h急性胁迫实验,测定肝脏和血清中抗氧化与免疫酶的活性及肝脏中相关基因的表达水平。结果显示,在不同浓度氨氮胁迫下,虹鳟肝脏CAT、T-AOC、T-SOD活性和MDA含量均呈现先上升后下降的变化趋势,血清T-AOC活性呈先下降后上升的变化,其他酶活性变化则与肝脏一致;高浓度组肝脏MDA含量在胁迫48h时最低,而T-SOD活性最高。肝脏和血清免疫相关酶GPT、GOT、ACP和AKP的活性在不同浓度的氨氮胁迫下呈先升高后降低的变化趋势;在96h时,不同浓度组肝脏和血清中GPT活性均显著高于对照组(P<0.05)。不同浓度组肝脏抗氧化相关基因(cu/zn-sod、mn-sod和cat)表达量在6h时均高于对照组;在12h时,hsp90基因的表达量高于对照组,而hsp70基因的表达量低于对照组。以上结果表明,在胁迫初期虹鳟抗氧化和免疫酶活性被诱导激活,抗氧化与免疫相关基因表达量上调;随着胁迫时间的延长,机体抗氧化与免疫功能受到抑制,相关酶活性与基因表达量下调。研究为深入探究虹鳟氨氮胁迫下抗氧化和免疫系统的应激机制提供了基础资料。

西南地区磷石膏建材易发生霉变,影响产品质量和人体健康,制约其资源化利用。为控制霉菌污染,本工作从霉菌生物结构和适存环境出发,以黑曲霉为感染源,分别采用耐霉菌性等级法、抑菌圈法和软化系数及抗压强度测定检测材料抗霉性能及物理力学性能,通过XRD、FT-IR和SEM等方法进行结构表征和微观形貌分析,构建无机碱性材料与有机季铵盐协同抗霉模型,探讨其抗霉机理。结果表明:单掺无机碱只能提升材料短期抗霉效果,且提升程度受pH、无机成分和吸湿性能共同调控;Ca(OH)_(2)和季铵盐的协同改性能获得优异抗霉效果与耐久性,但季铵盐掺杂会劣化其软化系数和抗压强度。复掺质量分数10%Ca(OH)_(2)和0.1%CTAB试件的物理力学性能较优;Ca(OH)_(2)和季铵盐协同增强抗霉作用在于:OH^(-)和季铵根离子分别以氢键和静电吸引作用稳定依附于CaSO_(4)·2H_(2)O晶体表面,前者让霉菌孢子生物膜系统的蛋白质变性后,后者对磷脂双分子层的破坏程度加剧,加速霉菌孢子失活,提高抗霉性。
