目的:探讨香烟烟雾及脂多糖(LPS)短期刺激对小鼠气道免疫细胞的影响。方法:LPS组小鼠气管内(一次性)滴注10μg LPS,熏烟组小鼠每天熏9支香烟持续熏4 d,观测不同干预措施对小鼠体重的影响;检测支气管肺泡灌洗液(BALF)总细胞数及细胞分类... 目的:探讨香烟烟雾及脂多糖(LPS)短期刺激对小鼠气道免疫细胞的影响。方法:LPS组小鼠气管内(一次性)滴注10μg LPS,熏烟组小鼠每天熏9支香烟持续熏4 d,观测不同干预措施对小鼠体重的影响;检测支气管肺泡灌洗液(BALF)总细胞数及细胞分类计数,观察细胞形态,并利用PDB(2-丁酸佛波醇酯)诱导BALF中的细胞检测ROS产出率;荧光定量PCR法检测肺组织中GM-CSF和CXCL15 m RNA表达。结果:与实验前相比,对照组及LPS组小鼠体重未见明显变化(P>0. 05),熏烟组小鼠体重减少了18. 9%,其变化差异明显高于对照组和LPS组(P<0. 01)。与对照组相比,熏烟组小鼠气道灌洗液细胞总数和各类细胞总数均无明显变化(P>0. 05); LPS组小鼠气道灌洗液细胞总数、巨噬细胞计数和中性粒细胞计数均高于对照组和熏烟组(P<0. 01),且LPS组灌洗液巨噬细胞体积较大,形态不规则,中性粒细胞胞核分叶较对照组多。LPS组小鼠气道灌洗液细胞在PDB的诱导下及没有PDB的诱导下均比对照组和熏烟组具有更高ROS产出率(P<0. 01)。与对照组相比,LPS组小鼠肺组织中GM-CSF表达显著增高(P<0. 01),但CXCL-15和熏烟组小鼠肺组织中GM-CSF及CXCL-15的表达并未发生改变(P>0. 05)。结论:短期香烟烟雾刺激明显引起小鼠体重下降,但未能诱发明显气道炎症反应; 10μg LPS气道滴注可通过增加肺组织GM-CSF的表达,增加中性粒细胞的成熟和募集,增加中性粒细胞内氧化应激反应及产生ROS的能力,诱发明显气道炎症反应。 展开更多

目的:研究头孢哌酮/舒巴坦联合替加环素治疗耐碳青霉烯类鲍曼不动杆菌感染的临床疗效及对患者急性生理与慢性健康评分(APACHE Ⅱ)评分及血清C-反应蛋白(CRP)、降钙素原(PCT)水平的影响,为预防和控制耐碳青霉烯类鲍曼不动杆菌感染提供依... 目的:研究头孢哌酮/舒巴坦联合替加环素治疗耐碳青霉烯类鲍曼不动杆菌感染的临床疗效及对患者急性生理与慢性健康评分(APACHE Ⅱ)评分及血清C-反应蛋白(CRP)、降钙素原(PCT)水平的影响,为预防和控制耐碳青霉烯类鲍曼不动杆菌感染提供依据。方法:选取2018年12月至2021年12月收集的80例耐碳青霉烯类鲍曼不动杆菌感染的患者为研究对象,所有受试者按抛掷硬币法随机分为观察组(40例)和对照组(40例)。对照组给予头孢哌酮/舒巴坦治疗,观察组给予头孢哌酮/舒巴坦联合替加环素治疗。治疗7 d后,比较两组治疗总有效率、细菌总清除率;比较治疗前后APACHE Ⅱ评分及CRP、PCT水平的变化。结果:治疗7d后,观察组总有效率为72.50%(29/40),明显高于对照组的40.00%(16/40),差异有统计学意义(P<0.05)。治疗7d后,观察组细菌总清除率为67.50%(27/40),高于对照组的30.00%(12/40),差异有统计学意义(P<0.05)。治疗前两组APACHE Ⅱ评分及CRP、PCT水平比较,差异均无统计学意义(P>0.05);治疗7d后,两组APACHE Ⅱ评分及CRP、PCT水平均有所下降,且观察组明显低于对照组,组间比较差异有统计学意义(P<0.05)。结论:头孢哌酮/舒巴坦联合替加环素治疗耐碳青霉烯类鲍曼不动杆菌感染的临床效果显著,有利于缓解患者的炎症反应,改善其临床症状及控制感染,值得临床推广应用。 展开更多

Objective To assess the efficacy and safety of Chinese medicine injection(CMI)for treating acute lung injury/acute respiratory distress syndrome(ALI/ARDS).Methods Randomized controlled trials(RCTs)were identified by searching 3 English databases and 4 Chinese databases from their inceptions until February 2019.The Cochrane Handbook was used to evaluate risk of bias in the included studies.Data analysis was conducted using RevMan 5.3.3 software.Results A total of 19 eligible RCTs involving 1,334 participants was included in this systematic review and meta-analysis.The main meta-analysis showed that CMI combined with conventional therapy(CT)was more effective than CT alone in reducing the acute physiology and chronic health evaluation(APACHE)H score[mean difference(MD):−1.74 points,95%confidence interval(CI):−2.77 to−0.71,I^2=0]and increasing the total effective rate[relative risk(RR):1.35,95%CI:1.17 to 1.56,I^2=37%].Compared with CT,CMI combined with CT showed improvements in the arterial partial pressure of oxygen(PaO2,MD:9.25 mm Hg,95%CI:0.87 to 17.63,I^2=98%)and oxygenation index[arterial partial pressure of oxygen(PaO2)/fraction of inspired oxygen(FiO2),MD:50.75 mm Hg,95%CI:35.18 to 66.31,I^2=94%].CMI plus CT was superior to CT in reducing the systemic inflammatory response syndrome(SIRS)score(MD:−0.84 points,95%CI:−1.26 to−0.42,I^2=65%),length of hospital stay(MD:−4.22 days,95%CI:−6.49 to−1.95,I^2=92%),and duration of mechanical ventilation(MD:−2.94 days,95%CI:−4.68 to−1.21,I^2=89%).Only 1 study reported adverse events.Conclusions CMI as an adjuvant therapy showed great potential benefits for the treatment of ALI/ARDS.However,we could not make a definite conclusion due to low quality of included studies and uncertain security.Future studies should focus on improving research design,especially in blindness and placebo.The reporting of adverse events was also needed. 展开更多
