目的评价超声引导下喉上神经阻滞结合环甲膜穿刺用于困难气道清醒插管的临床效果。方法采用前瞻性研究,以2019年8月至2023年2月武警海警总队医院择期进行全身麻醉手术的困难气道患者80例为研究对象,采用随机数字表法分为对照组(40例)和观察组(40例)。两组患者均实施纤维支气管镜(FOB)引导下经鼻清醒气管插管,插管前对照组实施表面麻醉结合环甲膜穿刺麻醉,对观察组实施超声引导下喉上神经阻滞(SLNB)联合环甲膜穿刺麻醉。监测患者插管过程中血流动力学指标,记录插管操作耗时,评价插管过程中镇静及呛咳反应程度,检测插管前后血清应激反应因子含量,调查患者对于插管操作的满意度。结果观察组气管导管进入声门即刻(T1)、气管导管进入气管后(T2)时点心率(HR)依次为(84.08±8.25)次/分,(82.64±7.81)次/分、平均动脉压(MAP)依次为(92.57±8.32)mmHg(1 mmHg=0.133 kPa),(103.27±9.16)mmHg均显著低于对照组(t=5.92~12.56,P<0.001),观察组与对照组各时点血氧饱和度(SpO_(2))差异均无统计学意义(t=0.34~0.43,P=0.652~0.726);观察组插管操作耗时(8.96±1.15)min,显著短于对照组的(11.47±1.39)min(t=6.84,P<0.001);观察组插管过程中Ramsay镇静评分3(2,3)分,显著高于对照组的2(1,3)分;而呛咳反应评分1(0,1)分,显著低于对照组的1(0,2)分(Z=9.26、4.37,均P<0.001);观察组血清去甲肾上腺素(NE)和肾上腺素(E)等应激反应因子含量均显著低于对照组(t=14.58~25.94,均P<0.05);观察组对于插管操作的总体满意度(97.50%)显著高于对照组(χ^(2)=4.51,P=0.034)。结论SLNB结合环甲膜穿刺用于困难气道清醒经鼻气管插管的麻醉管理,可提高患者血流动力学稳定性和镇静程度,缩短气管插管操作耗时,减轻操作过程应激反应,提高患者治疗满意度。

The objective of this study was to investigate the effects of natural capsicum extract(NCE,containing 2%natural capsaicin,the rest is carrier)replacing chlortetracycline(CTC)on performance,digestive enzyme activities,antioxidant capacity,inflammatory cytokines,and gut health in weaned pigs.A total of 108 weaned pigs(Duroc×[Landrace×Yorkshire],initial body weight-8.68±1.34 kg;weaned on d 28)were randomly allotted into 3 treatments with 6 replicate pens per treatment(3 barrows and 3 gilts per pen).The treatments include a corn-soybean meal basal diet as a control group(CON),a CTC group(basal diet+CTC at 75 mg/kg),and a NCE group(basal diet--NEC at 80 mg/kg).Compared with CON and CTC,NCE had increased(P<0.05)average daily gain in phase 2(d 15 to 28)and overall(d 1 to 28),and higher(P<0.05)apparent total tract digestibility of gross energy,dry matter,crude protein,and organic matter in phase 1(d 1 to 14).These pigs also had increased(P<0.05)pancrelipase activity in pancreas,α-amylase,lipase and protease activities in the jejunal mucosa,and lipase activity in the ileal mucosa on d ***,NCE had increased(P<0.05)the contents of growth hormone,β-endorphin,5-hydroxytryptamine,total antioxidant capacity,total superoxide dismutase,catalase,and IL-10,as well as decreased(P<0.05)contents of malondialdehyde,tumor nuclear factor-a,interferon-y,and interleukin-6 in serum on d 28 compared with CON and *** showed higher(P<0.05)propionic acid,butyric acid and total volatile fatty acids(VFA)contents,and increased(P<0.05)relative abundance of Faecalibacterium in colon,as well as higher(P<0.05)propionic acid and total volatile fatty acids in cecum on d 28 compared with *** conclusion,NCE replacing CTC could enhance performance via improving digestive enzyme activities,antioxidant capacity,anti-inflammatory function,gut VFA composition and microbiota community in weaned pigs,and it could be used as a potential target for the development of feed additives.

中国式检察机关支持起诉制度对于保障农村集体经济组织及其成员权益具有重要意义。仅具备框架性的法律依据,是导致农村集体经济领域支持起诉制度适用不足、效果不彰的根源。应从顶层设计完善民事诉讼法,明确支持起诉制度中检察机关的诉讼地位,细化诉讼规则。具体路径为:(1)明确支持起诉中检察机关定性限度;(2)完善支持起诉方式;(3)改变支持起诉启动模式;(4)支持起诉制度衔接相关法律,构建“诉前支持、诉中参与、诉后监督”的三阶递进民事支持体系。

The mammalian gut is inhabited by a massive and complicated microbial community, in which the hostachieves a stable symbiotic environment through the interdependence, coordination, reciprocal constraintsand participation in an immune response. The interaction between the host gut and themicrobiota is essential for maintaining and achieving the homeostasis of the organism. Consequently, guthomeostasis is pivotal in safeguarding the growth and development and potential productive performanceof the host. As metabolites of microorganisms, short chain fatty acids are not only the preferredenergy metabolic feedstock for host intestinal epithelial cells, but also exert vital effects on antioxidantsand the regulation of intestinal community homeostasis. Herein, we summarize the effects of intestinalmicroorganisms on the host gut and the mechanisms of action of short chain fatty acids on the fourintestinal barriers of the organism, which will shed light on the manipulation of the intestinal communityto achieve precise nutrition for specific individuals and provide a novel perspective for theprevention and treatment of diseases.
