Objective To investigate the effect of ultrasound monitoring guided early enteral nutrition（EEN）in patients with severe sepsis（SS）and invasive mechanical ventilation（IV）．Methods A total of 115 SS-IV patients admitted to Lianzhou People's Hospital from February 2021 to November 2023 were randomly divided into control group（n=57）and ultrasound monitoring group（n=58）．All patients were given comprehensive treatment in intensive care unit（ICU）．On this basis,traditional enteral nutrition（EN）intervention with clinical experience was implemented in control group,and EEN intervention guided by ultrasonic monitoring was implemented in ultrasound monitoring group．All patients were monitored until the end of treatment．IV time,ICU stay time,EN compliance time,incidence of EN intolerance,and incidence of related complications were analyzed in the 2 groups．Nutritional status [albumin（ALB）,total protein（TP）,prealbumin（PA）],sequential organ failure assessment（SOFA）,acute physiology and chronic health evaluation Ⅱ（APACHEⅡ）were compared before intervention and at the end of EN．Results In control group,1 cases gave up,2 cases died,and 54 cases were included．In ultrasound monitoring group,1 case gave up,1 case died,and 56 cases were included．The EN compliance time [（40.18±8.46）h],IV time [（7.12±1.44）d] and ICU stay time [（9.21±1.63）d] of ultrasound monitoring group were shorter than those of control group [（46.03±10.15）h,（8.02±1.62）d,（10.18±1.54）d]（t=3.288,3.082,3.206,all P<0.05）．At the end of EN,serum ALB[（32.05±3.13）g/L],TP[（65.36±3.62）g/L],PA[（0.24±0.06）g/L] of SS-IV patients in ultrasound monitoring group were higher than those in control group [（30.28±2.24）g/L,（63.28±4.24）g/L,（0.21±0.05）g/L]（t=3.400,2.770,2.843,all P<0.05）．At the end of EN,APACHEⅡ scores [（15.85±1.93）points] and SOFA scores [（7.42±1.64）points] of ultrasound monitoring group were lower than those of control group [（17.02±2.04）points and（8.35±2.03）points]（t=3.091,2.648,all P<0.05）．The incidence of EN intolerance in ultrasound monitoring group [12.50%（7/56）] was lower than that in control group [29.63%（16/54）],and the incidence of related complications in ultrasound monitoring group [8.93%（5/56）] was lower than that in control group [24.07%（13/54）]（χ²=4.878,4.608,all P<0.05）．Conclusions EEN intervention guided by ultrasonic monitoring in SS-IV patients can improve the nutritional status of patients,reduce the risk of EN intolerance and related complications,shorten the recovery time,and reduce the progression of patients' disease．

目的 研究CXC趋化因子配体4（CXCL4）、基质金属蛋白酶-9（MMP-9）、微小RNA-24（miR-24）对急性脑梗死（ACI）早期神经功能恶化（END）的预测价值。方法 分别选择2020年1月—2021年6月我院收治的30例ACI早期END患者（ACI+END组）,30例单纯ACI患者（ACI组）,同时期30例健康人群作为对照组,检测受试者CXCL4、MMP-9、miR-24表达情况及存在的相关性,分析血清CXCL4、MMP-9、miR-24表达情况与ACI早期发生END的关系。结果 CXCL4、MMP-9水平在对照组、ACI组、ACI+END组中依次升高,miR-24相对表达量依次降低（P<0.05）。血清CXCL4、MMP-9、miR-24水平在轻度、重度患者中呈升高趋势,miR-24相对表达呈降低趋势（P<0.05）。Logistic回归分析血清CXCL4、MMP-9、miR-24表达异常与ACI早期发生END独立相关（P<0.05）。经Pearson相关性分析发现,CXCL4与MMP-9之间呈正相关（r=0.584,P=0.001）;CXCL4、miR-24之间呈负相关（r=-0.569,P=0.001）,MMP-9、miR-24之间呈负相关（r=-0.567,P=0.001）。ROC曲线显示,与CXCL4、MMP-9、miR-24单项预测相比,三项联合对ACI的关系及对早期END的预测价值较高（P<0.05）。结论 CXCL4、MMP-9、miR-24在ACI发生END时出现异常表达,检测CXCL4、MMP-9、miR-24水平对ACI早期END具有一定预测价值,可尽早制定相关措施干预,提高治疗效率。

Objective To study the predictive value of CXC chemokine ligand 4（CXCL4）,matrix metalloproteinase-9（MMP-9）,microRNA-24（miR-24）in early neurological deterioration（END）of acute cerebral infarction（ACI）．Methods A total of 30 patients with ACI early END（ACI+END group）and 30 patients with ACI only（ACI group）who were admitted to our hospital from January 2020 to June 2021 were selected,and 30 healthy people（control group）who underwent physical examination in our hospital during the same period were selected．Expressions of CXCL4,MMP-9,and miR-24 were detected and their correlations were analyzed,and the relationship between the expressions of serum CXCL4,MMP-9,miR-24 and the early occurrence of END in ACI were analyzed．Results The levels of CXCL4 and MMP-9 were increased in the control group,ACI group and ACI+END group in turn,and the relative expression of miR-24 was decreased in turn,and the differences among the groups were statistically significant（P<0.05）．The levels of serum CXCL4,MMP-9,and miR-24 increased in mild and severe patients,while the relative expression of miR-24 decreased,and the differences between groups were statistically significant（P<0.05）．Logistic regression analysis showed that abnormal expressions of serum CXCL4,MMP-9 and miR-24 were independently correlated with the early occurrence of END in ACI（P<0.05）．After Pearson correlation analysis,it was found that there was a positive correlation between CXCL4 and MMP-9（r=0.584,P=0.001）,a negative correlation between CXCL4 and miR-24（r=-0.569,P=0.001）;a negative correlation between MMP-9 and miR-24（r=-0.567,P=0.001）．The ROC curve showed that compared with the single prediction of CXCL4,MMP-9 and miR-24,the predictive value of the combined prediction on ACI and early END were higher（P<0.05）．Conclusions CXCL4,MMP-9,and miR-24 are abnormally expressed in ACI when END occurs．Detection of CXCL4,MMP-9,and miR-24 levels has certain predictive value for early END of ACI,and relevant measures can be formulated as soon as possible to improve treatment efficiency．

Objective To investigate the effect of timing of neostigmine antagonizing cisatracurium on residual muscle relaxation and early lung function in patients underwent laparoscopic radical resection of colorectal cancer．Methods February 2021 to September 2022,194 patients who underwent radical colon cancer surgery in our hospital were selected as the research subjects．The patients were randomly divided into a blank control group and an experimental group using a random number table method．Then,combined with the train-of-four（TOF）ratios observed during neostigmine treatment,the experimental group patients were divided into experimental group A（TOF≤0.1）,experimental group B（0.10.8）．The residual muscle relaxation and lung function between groups were compared．Results Before intubation,the TOF ratio of patients in experimental group A was lower than that of other groups（P<0.01）,while the TOF ratio of patients in the blank control group was higher than that of other groups（P<0.01）．There was no significant difference in the observation time between the blank control group and the experimental group A~E in the postanesthesia care unit（P>0.01）．The muscle relaxation recovery index of patients in experimental group A was lower than that of other groups（P<0.01）,while the muscle relaxation recovery index of patients in the blank control group was higher than that of other groups（P<0.01）．There were no significant differences in force expiratory volume in one second（FEV1）,forced Vital capacity（FVC）and FEV1/FVC between groups before intubation,0.5 h after extubation and 24 h after extubation（P>0.05）．Conclusions Administration of neostigmine after radical surgery for colorectal cancer can accelerate muscle relaxation recovery,but it will not affect the residence time of the postanesthesia care unit and lung function levels．
