Objective To evaluate the diagnostic value of plasma procalcitonin (PCT) for bacterial infection in patients receiving extracorporeal membrane oxygenation (ECMO). Methods Clinical data of patients receiving ECMO therapy admitted between August 2016 and January 2018 in Department of Critical Care Medicine, Tongji Hospital of Tongji Medical College were analyzed retrospectively. All patients receiving ECMO with bacterial culture were eligible for inclusion. Plasma PCT, IL-6, CRP and WBC levels detected within 24 h of bacterial cultures were analyzed immediately. Bacterial infection in ECMO was determined through bacterial culture and clinical characteristics. Finally, receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic value of inflammatory markers for bacterial infection in ECMO patients. Results Seventeen patients met the inclusion criteria, including 15 patients with acute respiratory failure and 2 patients with acute circulatory failure. There were 37 positive bacterial cultures, and 91 plasma PCT levels were detected in the process of ECMO. Compared with IL-6, CRP and WBC, plasma PCT had significant clinical significance in the diagnosis of bacterial infection (AUC=0.818,P<0.001). The cut-off value of PCT was 1.0 ng/mL, with a sensitivity of 92% and a specificity of 43%. Conclusions Compared with other conventional inflammatory markers, plasma PCT has more diagnostic value for bacterial infection in ECMO patients.

Objective To investigate the effect of different ventilation modes on the ventilation rate and prognosis in patients with cardiac arrest after advanced airway placement. Methods Based on the national database of emergency cardiac arrest treatment, patients treated with advanced airway placement during cardiopulmonary resuscitation (CPR) were enrolled in PUMCH Emergency Department from December 2013 to June 2018. The physiological parameters, such as electrocardiograph waveform, pulse oximetry plethysmographic waveform and capnography, were recorded at least 18 minutes. The demographic data and resuscitation parameters were collected. Waveform capnography was used for calculating ventilation rate (VR) and the VR between 8 to 12 breaths/min was defined as the qualified ventilation rate (QVR). According to the ventilation modes, patients were divided into the bag-mask group (BMG) and mechanical ventilation group (MVG). According to the VR, patients in the mechanical ventilation group were divided into two subgroups, the high-frequency ventilation subgroup (HFV subgroup) with the VR more than 20 breaths/min and the low-frequency VR subgroup (LFV subgroup) with the VR less than 20 breaths/min. VR, the qualified ventilation rate ratio (QVRR), the return of spontaneous circulation (ROSC), and 24-h and 7-day survival were compared between the two groups and subgroups. Result A total of 90 patients were enrolled in the analysis with 22 patients in the bag-mask group and 68 patients in the mechanical ventilation group. The total rate of ROSC was 35.6%, 24-h survival was 1.1% and 7-day survival was 0. The first 18 minutes ventilation data were collected and added up to 1 620 min. The median VR was 16.5 (12.0, 26.0) breaths/min and the QVRR was 30%. Compared with the mechanical ventilation group, the VR in the bag-mask group were lower (10 breaths/min vs 21 breaths/min) and the QVRR was higher (88.9% vs 11.5%). The ROSC, 24-h survival and 7-day survival had no statistical differences between the two groups. In the mechanical ventilation group, the ratio of VR more than 20 breaths/min was 52.6%. Between the two subgroups, there was no statistical difference in ROSC, 24-h survival and 7-day survival. Conclusions Compared with the mechanical ventilation during CPR, the VR is lower with bag-mask ventilation, and the QVRR is higher. But there was no statistical difference on the outcomes. There was no difference on the outcomes between the two mechanical ventilation subgroups.

Objective To study the effect of high-flow nasal cannula oxygen therapy (HFNC) in reduction in re-intubation rate, length of ICU stay and improvement of respiratory function in patients with high cervical spinal cord injury. Methods Single center retrospective study was carried out in our intensive care unit from September 2016 to March 2018. Post-operative patients ready for planned extubation with high cervical spinal cord injury were included. The length of ICU stay, re-intubation rate in case of respiratory failure, respiratory rate, pulse rate, MAP, SaO2, PaO2/FiO2, and PaCO2 of patients at 6, 24 and 72 h after extubation were compared between the HFNC and conventional oxygen therapy (COT) groups. Results During the study period, 38 patients were enrolled in the study. Of them, 16 patients were assigned in the HFNC group and 22 patients in the COT group. Re-intubation rate was significantly different between the two groups (18.8% vs 27.3%, P<0.05), but the length of ICU stay had no significant difference [(15.5±3.4) days vs (16.6±5.2) days]. The respiratory rate, pulse rate, SaO2 and PaO2/FiO2 at 6 h after extubation in the HFNC group were improved markedly than those in the COT group (P<0.05); and the PaCO2 and PaO2/FiO2 at 24 and 72 h after extubation in the HFNC group had much more improvement than those in the COT group (P<0.05). Conclusions Among individuals with post-operative high cervical spinal cord injury, high-flow oxygen therapy could reduce re-intubation rate, and PaCO2 level, and improve the respiratory function, but cannot reduce the length of ICU stay. High-flow oxygen therapy may offer advantages for patients with high cervical spinal cord injury.

Objective To investigate the role of activated cannabinoid receptor 2 (CB2R) in lipopolysaccharide (LPS)-induced secretion of RAW264.7 macrophage inflammatory cytokines and its possible mechanism. Methods Macrophages were seeded in 6-well plates (2 mL/well) at the density of 1×105 cells/mL and randomly divided into four groups (n=6 each group): control group (group C), LPS group (group LPS), LPS plus CB2R agonist HU308 group (group LPS+HU308), and LPS plus HU308 plus 3-Methyladenine group (group LPS+HU308+3-MA). LPS with the final concentration of 1 μg/mL were added in group LPS, group LPS+HU308 and group LPS+HU308+3-MA. After incubation for 15 min, 3-MA with a final concentration of 10 mmol/L was added into group LPS+HU308+3-MA . HU308 with the final concentration of 10 μmol/L was added in group LPS+HU308 and group LPS+HU308+3-MA at 15 min after 3-MA intervention, and the cells were then incubated for 24 h. The concentrations of TNF-α, IL-18 and IL-1β in supernatant serum of each group were determined by ELISA. The expressions of ICAM-1 and NLRP3 mRNA were detected by RT-PCR. The expressions of LC3 and Beclin1 were detected by Western blot, and the ratio of LC3-II/LC3-I was calculated. LSD-t test was used for sample pairwise comparison, and one way ANOVA for inter-group comparison. A P<0.05 was considered statistically significant. Results Compared with group C, the concentrations of TNF-α [(228.86±10.20) pg/mL vs (140.05±5.54) pg/mL], IL-1β [(363.62±8.14) pg/mL vs (244.82±9.11) pg/mL], and IL-18 [(293.28±13.57) pg/mL vs (202.84±9.54) pg/mL] in supernatant serum were increased (all P<0.05), the expressions of ICAM-1 [(5.88±0.32) vs (1.00±0.03)] and NLRP3 [(8.07±0.93) vs (1.01±0.05)] mRNA were increased (all P<0.05), the expressions of LC3-II/LC3-I ratio [(0.50±0.03) vs (0.40±0.06)] and Beclin1 [(0.51±0.04) vs (0.16±0.03)] were up-regulated in group LPS (all P<0.05). Compared with group LPS, the concentrations of TNF-α [(165.44±7.07) pg/mL], IL-1β [(272.09±3.35) pg/mL] and IL-18 [(220.41±6.01) pg/mL] in supernatant serum were significantly decreased (all P<0.05), the expressions of ICAM-1 [(3.21±0.35)] and NLRP3 [(1.54±0.30)] mRNA were decreased (all P<0.05), the expressions of LC3-II/LC3-I ratio [(0.71±0.03)] and Beclin1 [(0.71±0.02)] were up-regulated in group LPS+HU308 (all P<0.05). Compared with group LPS+HU308, the concentrations of TNF-α [(197.06±5.59) pg/mL], IL-1β [(318.98±11.54) pg/mL] and IL-18 [(243.33±8.71) pg/mL] in supernatant serum were significantly increased (all P<0.05), the expressions of ICAM-1 [(4.04±0.21)] and NLRP3 [(5.87±0.77)] mRNA were increased (all P<0.05), the expressions of LC3-II/LC3-I ratio [(0.44±0.08)] and Beclin1 [(0.32±0.03)] were down-regulated in group LPS+HU308+3-MA (all P<0.05). Conclusions Activation of cannabinoid receptor 2 can alleviate LPS-induced the secretion of RAW264.7 macrophage inflammatory cytokines, and its mechanism may be related to enhanced autophagy.

Objective To investigate the mechanism of cerebral protection by treatment of butylphthalide (NBP) and its effect to mitochondria in a porcine model of cardiac arrest (CA) after cardiopulmonary resuscitation (CPR). Methods Healthy Wuzhishan pigs weighting (30±2) kg were divide into three groups randomly(random number): The sham group (n=6), the control group (n=12) and the NBP group (n=12). Operation was performed in the sham group. Cardiac arrest of ventricular fibrillation was induced by programed electrical stimulation in the control and NBP group. After CPR, asynchronous defibrillation of 150J was performed to achieve the restoration of spontaneous circulation. NBP was injected at the rate of 2.5 mg•kg-1 in the NBP group. Hemodynamics were recorded at baseline, 1 hr, 2 hr, 3 hr and 4 hr after CPR. The number of injured neurons, apoptosis index and evaluation of mitochondrial injury were calculated under light and electrical microscope respectively. Mitochondria were separated by differential centrifugation. Mitochondrial respiratory function was measured with oxygen consumption of R3 and R4, respiratory control rate (RCR), ADP/oxygen. Mitochondrial permeability transition pore (MPTP) open was tested by colorimetric. Results After CPR, the mean artery pressure, coronary perfusion pressure and cardiac output decreased significantly, whereas no significant differences were found between the control and NBP group (P>0.05). Significant cerebral injury was found after CPR. The number of injured neurons, apoptosis index and evaluation of mitochondrial injury were improved significantly by the NBP treatment (P<0.05). Compared with the sham group, oxygen consumption of R3 and R4, R3/R4 and ADP/O decreased significantly in the cerebral frontal cortex mitochondria of the control group (P<0.01), whereas they were increased in the NBP group (P<0.01). MPTP increased in the control group, which could be improved by the NBP treatment. Conclusions NBP can improve the neurologic outcome after CPR and decrease the apoptosis of neurons by improving the respiratory function of mitochondria and inhibiting the MPTP opening.

Objective To investigate the protective effect of Baicalin on inflammation induced by lipopolysaccharide in H9C2 cardiomyocytes and its possible mechanism. Methods H9C2 myocardial cells were cultured and pretreated with baicalin at the final concentration of 10, 20, 30 μmol/L for 12 hours, then stimulated with LPS at the final concentration of 1 μg/mL for 6 hours. The control group was treated with the same amount of saline to collect cell samples. CCK-8 (The Cell Counting Kit-8) was used to detect cell activity, enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of interleukin-6 (IL-6), interleukin-1beta (IL-1β), tumor necrosis factor-alpha (TNF-α), Western blot was used to detect the protein expression levels of NF-κB p65, p-NF-κB p65, p38 MAPK, p-p38 MAPK, IκBα and p-IκBα. SPSS 23.0 statistical software was used. Independent sample t test was used for comparison between two groups, and one-way ANOVA test was used for comparison among multiple groups. Results The survival rate of myocardial cells in the control group was (93.67 +1.453)%. Compared with the control group, the survival rate of H9C2 myocardial cells induced by LPS decreased (P 0.05). Compared with LPS group, the survival rate of H9C2 myocardial cells in baicalin intervention group increased (P 0.05). Conclusions Baicalin may alleviate LPS-induced cardiomyocyte inflammation by inhibiting the activation of NF-kappa B and p38 MAPK, and improve cell survival.

Objective To explore the applicability of the three commonly used CT examination decision rules in Chinese head injured children. Methods This prospective observational study included 1 538 children and adolescents (aged <18 years), who were treated at the Emergency Department of First Hospital of Shanxi Medical University after head injuries. The three clinical decision rules include the Children’s Head Injury Algorithm for the Prediction of Important Clinical Events (CHALICE; UK); the prediction rule for the identification of children at very low risk of clinically important traumatic brain injury, that was developed by the Pediatric Emergency Care Applied Research Network (PECARN; USA), and the Canadian Assessment of Tomography for Childhood Head Injury (CATCH) rule. Diagnostic accuracy had been evaluated by using the rule-specific predictor variables to predict each rule-specific outcome measure in populations who met inclusion and exclusion criteria for each rule. Sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and ROC curve were referred to the diagnostic accuracy. Indicators were characterized by 95% CI. Results Of the 1 538 patients, CTs were obtained for 339 patients (22.04%). Forty-nine patients (3.19%) had positive CT results, 8 patients (0.52%) underwent neurosurgery, 2 patients (0.13%) died, and 1 patient (0.07%) may be missed. In this study, CHALICE was applied for 1 394 children (90.70%; 95% CI: 89.24%-92.15%), PECARN for 801 children (52.11%; 95% CI: 49.62%-54.61%), and CATCH for 325 patients (21.15%; 95% CI: 19.10%-23.19%). The validation sensitivities of CHALICE, PECARN, and CATCH rules were 92.6% (74.2%-98.7%), 100% (56.1%-100%), and 85.7% (42.0%-99.2%), respectively; the specificities were 78.1% (75.7%-80.2%), 48.0% (44.5%-51.5%) and 70.8% (65.4%-75.6%); positive predictive value were 7.7% (5.1%-11.3%), 0.9% (0.4%-1.9%) and 6.1% (2.5%-13.2%); and negative predictive value were 99.8% (99.2%-100%), 99.1% (98.1%-99.6%), and 99.6% (97.2%-100%), respectively. Conclusions The clinical decision rules of CHALICE, PECARN and CATCH have high sensitivities. The specificity of PECARN rule is lower than those of CHALICE and CATCH rules. The above three clinical decision rules can be used for the decision of CT examination in Chinese children with head injury in practice.

In this study, CHALICE was applied for 1 394 children (90.70%; 95% CI: 89.24%-92.15%), PECARN for 801 children (52.11%; 95% CI: 49.62%-54.61%), and CATCH for 325 patients (21.15%; 95% CI: 19.10%-23.19%). The validation sensitivities of CHALICE, PECARN, and CATCH rules were 92.6% (74.2%-98.7%), 100% (56.1%-100%), and 85.7% (42.0%-99.2%), respectively; the specificities were 78.1% (75.7%-80.2%), 48.0% (44.5%-51.5%) and 70.8% (65.4%-75.6%); positive predictive value were 7.7% (5.1%-11.3%), 0.9% (0.4%-1.9%) and 6.1% (2.5%-13.2%); and negative predictive value were 99.8% (99.2%-100%), 99.1% (98.1%-99.6%), and 99.6% (97.2%-100%), respectively. \u0000 \u0000 \u0000Conclusions \u0000The clinical decision rules of CHALICE, PECARN and CATCH have high sensitivities. The specificity of PECARN rule is lower than those of CHALICE and CATCH rules. The above three clinical decision rules can be used for the decision of CT examination in Chinese children with head injury in practice. \u0000 \u0000 \u0000Key words: \u0000Children; Head trauma; CT examination; Clinical decision rules; Applicability; CATCH; PECARN; CHALICE","PeriodicalId":9981,"journal":{"name":"中华急诊医学杂志","volume":"28 1","pages":"956-961"},"PeriodicalIF":0.0,"publicationDate":"2019-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47920258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective To explore the effect of noninvasive ventilation (NIV) with helmet or facial mask on clinical efficacy, tolerability, and prognosis in patients with acute respiratory failure. Methods Fifty patients with acute respiratory failure according to the inclusion criteria were recruited from January 2018 to July 2018 in Emergency Intensive Care Unit of the First Affiliated Hospital of Zhengzhou University. Included patients were randomly allocated into the helmet group or facial mask group. Based on conventional drug therapy, pressure support mode was performed with the interface of the helmet or facial mask. Oxygenation index, arterial carbon dioxide partial pressure, and respiratory rates were measured before and after the treatment, and the data were compared and analyzed by the repeated measures ANOVA. Tolerance score, complication rate, tracheal intubation rate, and mortality rate were recorded at each observation time point of the two groups. Results The oxygenation index before NIV, at 4 h and at the end of NIV treatment of the helmet group were significantly increased from (160.29±50.32) mmHg to (249.29±83.47) mmHg and (259.24±87.09) mmHg; the oxygenation index of the facial mask group were increased from (168.63±38.63) mmHg to (225.00±74.96) mmHg and (217.69±77.80) mmHg, and there was no significant difference within the two groups (P 0.05). Patients in the helmet was better tolerated than those in the facial mask group [ratio of good tolerance 96% (24/25) vs 56% (14/25) (P = 0.001) and fully tolerance 80% (20/25) vs 36% (9/25) (P =0.002)] and had less complications (1/25 vs 10/25, P = 0.002). 84% patients in the helmet group and 76% patients in the facial mask group were successfully weaned and discharged after NIV treatment (P =0.480). Conclusions Similar clinical efficacy in improving blood gas exchange and relieving dyspnea were observed in the helmet group and the facial mask group in patients with acute respiratory failure. However, the helmet is better tolerant, and had lower complication rate, which is especially suitable for patients with chest trauma combined with facial injuries. Key words: Helmet; Facial mask; Noninvasive ventilation; Acute respiratory failure; Chest trauma; Randomized controlled trial
目的探讨头盔或面膜无创通气(NIV)对急性呼吸衰竭患者的临床疗效、耐受性和预后的影响。方法根据纳入标准,于2018年1月至2018年7月在郑州大学第一附属医院急诊重症监护室招募50例急性呼吸衰竭患者。纳入的患者被随机分为头盔组或面膜组。在传统药物治疗的基础上,通过头盔或面膜的接口进行压力支持模式。在治疗前后测量氧合指数、动脉二氧化碳分压和呼吸频率,并通过重复测量方差分析对数据进行比较和分析。记录两组在每个观察时间点的耐受性评分、并发症发生率、气管插管率和死亡率。结果头盔组NIV前、4 h及NIV结束时氧合指数由(160.29±50.32)mmHg显著升高至(249.29±83.47)mmHg和(259.24±87.09)mmHg;面膜组氧合指数由(168.63±38.63)mmHg增至(225.00±74.96)mmHg和(217.69±77.80)mmHg,头盔组患者耐受性优于面膜组[良容率96%(24/25)vs 56%(14/25)(P=0.001),全容率80%(20/25)vs 36%(9/25)(P=0.002)],并发症较少(1/25 vs 10/25,P=0.002)结论头盔组和面膜组急性呼吸衰竭患者改善血气交换、缓解呼吸困难的临床疗效相似。然而,该头盔具有更好的耐受性,并发症发生率较低,特别适合胸部创伤合并面部损伤的患者。关键词:头盔;面膜;无创通气;急性呼吸衰竭;胸部创伤;随机对照试验

Objective To measure the reads numbers of Human Herpes Virus in blood sample from patients with sepsis by using Next Generation sequencing (NGS) and explore the relationship between read number of virus and the severity, prognosis, immune status of septic patients. Methods Blood sample and clinical information from 150 patients with sepsis were enrolled in this study. All patients’ blood samples were sent to perform NGS pathogenic test. According to the results of NGS, septic patients were divided into HHV-detected group and HHV-undetected group. Besides, patients were scored with Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) on the day of blood collection. The counts of total leukocytes, lymphocytes and the levels of cytokines were also measured. Results 51.3 percent of septic patients were detected with HHV nucleic acid. The APACHE II and SOFA scores were significantly higher in HHV-detected patients compared with patients in HHV-undetected group. Besides, patients who had a higher SOFA score might lead to a higher detection rate of HHV. Moreover, the 28-day and 90-day mortality rates were higher in detected group (P < 0.01). The detection of HHV nucleic acid was positively correlated with a high 90-day mortality rate (P = 0.0056). One-way analysis of variance revealed that the counts of total lymphocyte and different types of lymphocyte (CD19+B、CD4+T、CD8+T、CD56+ lymphocyte) were significantly less in detected group than that in undetected group. Furthermore, both the levels of pro-inflammatory cytokines (TNF-α、IL-2R、IL-6、IL-8) and anti-inflammatory cytokines (IL-10) in detected group were significantly higher than those in undetected group. Gender, age, APACHEⅡ, SOFA, IL-2R, IL-10, CD19+B lymphocyte and T cells, were still significant even after multivariate logistic analyses. Conclusions The detection rate of HHV nucleic acid in patients with sepsis was high. The detection of HHV was a high-risk factor of death in patients with sepsis. The cut-off value which is more than 100 had a significant clinical value. The infection of HHV could be conducted by dysfunction of immunity.

目的应用Next Generation sequencing (NGS)技术检测脓毒症患者血样中人类疱疹病毒的reads数,探讨病毒reads数与脓毒症患者严重程度、预后、免疫状态的关系。方法收集150例脓毒症患者的血样及临床资料。所有患者血样均送行NGS致病性检测。根据NGS结果将脓毒症患者分为hhv检测组和未检测组。并于采血当天对患者进行顺序器官衰竭评估(SOFA)和急性生理与慢性健康评估Ⅱ(APACHEⅡ)评分。同时测定白细胞总数、淋巴细胞计数和细胞因子水平。结果51.3%的脓毒症患者检出HHV核酸。检测到hhv的患者APACHE II和SOFA评分明显高于未检测到hhv的患者。此外,SOFA评分较高的患者可能导致HHV的检出率较高。检测组28天、90天死亡率均高于对照组(P < 0.01)。HHV核酸检测与高90天死亡率呈正相关(P = 0.0056)。单因素方差分析显示,检测组总淋巴细胞计数及不同类型淋巴细胞(CD19+B、CD4+T、CD8+T、CD56+淋巴细胞)计数均显著低于未检测组。检测组的促炎因子(TNF-α、IL-2R、IL-6、IL-8)和抗炎因子(IL-10)水平均显著高于未检测组。性别、年龄、APACHEⅡ、SOFA、IL-2R、IL-10、CD19+B淋巴细胞和T细胞在多因素logistic分析后仍有显著性差异。结论HHV核酸在脓毒症患者中的检出率较高。HHV的检测是脓毒症患者死亡的高危因素。临界值大于100具有显著的临床价值。HHV的感染可能是由免疫功能障碍引起的。关键词:脓毒症;新一代测序;人类疱疹病毒;免疫statusCLC: R459.7
