ABSTRACT
Objective:To investigate the effect of continuous hemoperfusion (HP) on the levels of soluble CD14 isoform (sCD14-st) and neutrophil gelatinase-associated lipocalin (NGAL) on patients with diquat (DQ) poisoning and its significance.Methods:A total of 86 patients with acute DQ poisoning admitted to the department of emergency medicine, Harrison International Peace Hospital Affiliated to Hebei Medical University from May 2018 to August 2021 were enrolled and divided into the intermittent HP group (40 cases) and the continuous HP group (46 cases) according to the random number table method. All patients received basic treatment and continuous veno-venous hemofiltration (CVVH) within 24 hours after admission. On this basis, the intermittent HP group received HP treatment within 2 hours, lasting 2 hours each time for every 8 hours, 3 times in all; the continuous HP group received continued HP treatment until there was no DQ component in urine samples. Serum NGAL levels were detected in all patients before treatment and at 3 hours, 12 hours, 24 hours, 2 days, 3 days, 5 days, and 7 days after treatment. At the same time, serum sCD14-st, blood lactate (Lac), arterial partial pressure of oxygen (PaO 2), serum creatinine (SCr), MB isoenzyme of creatine kinase (CK-MB) and interleukin-18 (IL-18) levels were detected before treatment and at 24 hours, 3 days, and 7 days after treatment. Kaplan-Meier survival curve was drawn to analyze the 28-day survival of patients. Results:Before treatment, there was no significant difference in serum NGAL, sCD14-st, Lac, PaO 2, SCr, CK-MB and IL-18 levels between the two groups. With the prolongation of treatment, the serum levels of NGAL, sCD14-st, Lac, SCr, CK-MB and IL-18 in the intermittent HP group increased at first and then decreased. Serum levels of NGAL, sCD14-st, CK-MB and IL-18 reached their peaks at 24 hours after treatment, and the Lac and SCr levels reached their peaks at 3 days after treatment. In addition, the levels of the above indexes at each time point in the continuous HP group were all significantly lower than those in the intermittent HP group [after 24 hours of treatment: NGAL (μg/L) was 345.90±30.75 vs. 404.24±38.79, sCD14-st (ng/L) was 1 941.88±298.02 vs. 2 656.35±347.93, CK-MB (U/L) was 30.67±9.11 vs. 43.28±8.06, IL-18 (ng/L) was 139.49±16.29 vs. 177.98±27.85; 3 days of treatment: Lac (mmol/L) was 2.98±0.26 vs. 3.72±0.49, SCr (μmol/L) was 125.01±24.24 vs. 156.74±28.88; all P < 0.05]. However, there was no significant difference in PaO 2 levels between the two groups at each time point after treatment. The Kaplan-Meier survival curve showed that the 28-day mortality of patients in the continuous HP group was significantly lower than that in the intermittent HP group [26.09% (12/46) vs. 52.50% (21/40); Log-Rank test: χ2 = 7.288, P = 0.007]. Conclusion:Continuous HP could effectively reduce serum sCD14-st, NGAL levels and 28-day mortality in patients with DQ poisoning, with good curative effect.
ABSTRACT
Objective:To explore the value of neutrophil gelatinase-associated lipocalin(NGAL)and neutrophil-to-lymphocyte and platelet ratio(NLPR)for early prediction of kidney injury with Diquat(DQ)poisoning in elderly patients.Methods:In this retrospective study, a total of 106 elderly patients with DQ poisoning treated in the Emergency Intensive Care Unit(EICU)of Harrison International Peace Hospital Affiliated to Hebei Medical University between October 2019 and October 2021 were divided into an acute kidney injury group(AKI group, n=62)and a non-acute kidney injury group(NAKI group, n=44). Meanwhile, 40 non-elderly patients with DQ poisoning served as the control group.Samples of 5 ml venous blood were collected from patients admitted to the EICU to measure NGAL and NLPR levels and Logistic regression analysis was conducted to analyze independent risk factors for AKI in elderly DQ poisoning patients.The area under the curve(AUC)was calculated via the receiver operating characteristic(ROC)curve, and the value of NGAL and NLPR for early prediction of AKI in elderly patients with DQ poisoning and patient prognosis was assessed.Results:Blood NGAL and NLPR levels in the AKI group were significantly higher than in the NAKI group[(387.1±46.6)μg/L vs.(103.5±18.6)μg/L, (13.5±3.4) vs.(5.3±1.1), t=38.243, 15.608, P<0.001 for both]. Logistic regression analysis results showed that elevated levels of NGAL( OR=1.009, 95% CI: 1.003-1.015, P<0.001)and NLPR( OR=1.263, 95% CI: 1.039-1.536, P<0.001)were risk factors for AKI in elderly patients with DQ poisoning.The areas under the ROC curves of NGAL, NLPR and NGAL+ NLPR for AKI prediction were 0.834, 0.803 and 0.873 respectively.The predictive power of NGAL and NLPR for the death of elderly patients with DQ poisoning was higher than that of creatinine clearance(Ccr). The sensitivity of the combination of the two to predict the risk of death was 0.850, the specificity was 0.828, and the AUC was 0.887. Conclusions:NGAL and NLPR are independent risk factors for the occurrence of AKI in elderly patients with DQ poisoning.Combined detection of NGAL and NLPR improves AKI prediction and prognosis assessment in elderly patients with DQ poisoning.
ABSTRACT
Objective:To explore the predictive value of peripheral perfusion index (PI) combined with central venous-arterial carbon dioxide tension to arterial-venous oxygen content ratio(Pv-aCO 2/Ca-vO 2)for prognosis after initial resuscitation of septic shock. Methods:A total of 76 cases of patients with septic shock from January 2019 to January 2021 in emergency intensive care unit (EICU) of Harrson international peace hospital affiliated to Hebei Medical University were enrolled. All recovered according to 2016 Severe Sepsis and Septic Shock Treatment International Guidelines 2016 (SSC 2016) , and PI was monitored, central vein and arterial blood gas analysis was performed, and the ratio of Pv-aCO 2/Ca-vO 2 was calculated.The PI and Pv-aCO 2/Ca-vO 2 at 3 h,hemodynamic variables,oxygen metabolism indexes,APACHEⅡ and SOFA score were recorded.Patients were divided into survival group and death group according to 28 d survival condition, the dfferences in demographics and clinical data were compared between two groups.The Kaplan-Meier urviving curve was created and the survival of the patients was analyzed by the Log-rank test. Risk factors associated with the prognosis were analyzed using the Cox regression analysis. The role of PI and Pv-aCO 2/Ca-vO 2 in prediting death was evaluated by receiver operating characteristic curves(ROC). Results:There were 37 cases in survival group and 39 cases in death group.Compared with death group, PI in survival group [(1.77±0.63) vs. (0.89±0.69)]was significantly higher,and Pv-aCO 2/Ca-vO 2[(1.52±0.52) vs. (2.57±0.86)] was significantly lower ( P<0.05). Kaplan-Meier survival curve showed that the median survival time in the high PI group [20.09 d (95% CI:16.95-23.24) vs.11.00d (95% CI:7.14-14.86)] was longer than that in the low PI group(χ 2=12.424, P=0.000),and that in low Pv-aCO 2/Ca-vO 2 group [23.74 d (95% CI:20.35-27.13) vs.12.85d (95% CI:9.75-15.95)] was longer than that in the high Pv-aCO 2/Ca-vO 2 group (χ 2=12.200, P=0.000) .Cox regression analysis showed that both PI ( RR=0.397, 95% CI: 0.230-0.687, P =0.001) and Pv-aCO 2/Ca-vO 2 ( RR=1.878, 95% CI: 1.169-3.019, P =0.009) were predictors of 28 d mortality.The area under the ROC curve of PI and Pv-aCO 2/Ca-vO 2 for predicting 28 d death in patients with septic shock were 0.828 (95% CI: 0.732-0.923) and 0.785 (95% CI: 0.6777-0.893)respectively. The optimal cutoff values were 0.52 (sensitivity 58.3% and specificity 94.4%) and 0.35 (sensitivity 88.9% and specificity 63.9%)respectively, and the AUC of the combined prediction of the two indicators was 0.903 (95% CI: 0.835-0.971). Conclusions:Combination of PI and Pv-aCO 2/Ca-vO 2 is better to predict the risk of adverse outcomes of septie shock patients,and may provide useful information for the resuscitation at early stage.
ABSTRACT
Objective:To investigate clinical value of early cerebral oxygen utilization(O 2UCc)combined with the bispectral index(BIS)for monitoring delayed encephalopathy after acute carbon monoxide poisoning(DEACMP)in elderly patients. Methods:This was a retrospective analysis.A total of 90 elderly patients with acute severe carbon monoxide poisoning(ASCMP)treated in Harrison International Peace Hospital from Nov.2018 to Jan.2020 were considered as research objects.Patients were divided into the DEACMP group(n=25)and the good prognosis group(n=65)according to their prognosis.Oxygen quantity absorbed into UCC(O 2UCc)and Bispectral index(BIS)at different times in the early stages were compared between the two groups.Correlations of O 2UCc and BIS with the occurrence of DEACMP were analyzed.Clinical significance of O 2UCc or BIS alone and of the two parameters in combination for the prediction of DEACMP was investigated. Results:O 2UCc was higher and BIS was lower in the DEACMP group than in the good prognosis group at 0 h, 6 h, 12 h, and 24 h after admission(all P<0.01). Pearson correlation analysis showed that O 2UCc was negatively correlated with DEACMP( r0 h=-0.482, r6 h=-0.534, r12 h=-0.587, r24 h=-0.514, all P<0.01), BIS was positively correlated with DEACMP( r0 h=0.348, r6 h=0.583, r12 h=0.679, r24 h=0.489, all P<0.01), and the correlation was the strongest at 12h after admission.ROC curve analysis was performed with O2UCc, BIS and the combined predictors at 12 h, and the results showed that the areas under the ROC curve of O 2UCc, BIS and the two in combination for DEACMP prediction were 0.845, 0.850 and 0.909, respectively, the sensitivities were 78.5%, 90.8% and 96.9% and the specificities were 80.0%, 76.0% and 84.0%, respectively. Conclusions:Early detection of O 2UCc or BIS has a good clinical value for predicting the development of ASCMP to DEACMP, and their combined value is even better.
ABSTRACT
Objective:To investigate the predictive neutrophil/lymphocyte ratio (NLR) combined with soluble growth stimulating expression gene 2 protein (sST2) on in-hospital major adverse cardiovascular events (MACE) in patients with myocardial injury following moderate-severe acute carbon monoxide poisoning (ACOP).Methods:A single-cente prospective observational approach was conducted. Moderate-severe ACOP patients with myocardial damage from November 2016 to February 2020 in department of emergency medicine of Harrison International Peace Hospital Affiliated to Hebei Medical University were enrolled. The baseline data of the patients, NLR and sST2 (T0 sST2) on admission, sST2 at 3 days after admission (T3 d sST2), and the other myocardial injury and biochemical indicators were collected. According to whether MACE occurred, the patients were divided into MACE group and non-MACE group. The clinical data of the two groups were compared. Pearson correlation analysis was used to analyze the correlation of each index. Binary Logistic regression was used to analyze the independent risk factors of in-hospital MACE in patients with moderate-severe ACOP myocardial injury. The receiver operator characteristic curve (ROC curve) was drawn and area under ROC curve (AUC) was calculated to analyze the predictive value of NLR, sST2, and NLR combined with sST2 for the occurrence of in-hospital MACE in patients with moderate-severe ACOP myocardial injury.Results:A total of 278 patients with moderate-severe ACOP myocardial injury were included in the final analysis, and the incidence of MACE was 11.51% (32/278). Cardiac troponin I (cTnI), lactic acid (Lac), NLR, and T3 d sST2 in the MACE group were significantly higher than those in the non-MACE group [cTnI (μg/L): 0.83±0.15 vs. 0.46±0.37, Lac (mmol/L): 2.96±1.14 vs. 2.43±1.35, NLR: 13.14±4.37 vs. 9.49±4.21, T3 d sST2 (μg/L): 59.88±23.42 vs. 39.83±12.60, all P < 0.05], there was no significant difference in T0 sST2 between the MACE group and the non-MACE group (μg/L: 269.09±90.89 vs. 240.14±113.02, P > 0.05). Pearson correlation analysis showed that there were significantly positive correlations in NLR with acute physiology and chronic health evaluationⅡ(APACHEⅡ), T3 d sST2 with APACHEⅡ, and NLR with T3 d sST2 ( r values were 0.226, 0.209, 0.193, all P < 0.01). Binary Logistic regression analysis showed that T3 d sST2 and NLR were both independent risk factors for MACE in moderate-severe ACOP patients with myocardial injury [odds ratio ( OR) and 95% confidence interval (95% CI) respectively was 1.064 (1.039-1.090), 1.176 (1.066-1.298), both P < 0.01]. ROC curve analysis showed that the predictive efficacy of NLR combined with T3 d sST2 for the occurrence of in-hospital MACE in patients with ACOP myocardial injury (AUC = 0.876) was better than that of NLR (AUC = 0.754) and T3 d sST2 (AUC = 0.813). When the optimal critical value of NLR was 10.02 and that of T3 d sST2 was 43.50 μg/L, the sensitivity of predicting the occurrence of MACE in patients with moderate-severe ACOP myocardial injury was 69.8% and 86.2% respectively, and the specificity was 74.3% and 70.4%, respectively. The specificity and sensitivity of the combined detection was 83.4% and 79.8%, respectively. Conclusions:NLR and T3 d sST2 were independent predictors of in-hospital MACE in moderate-severe ACOP patients with myocardial injury, and combined application of NLR and T3 d sST2 had good predictive value. For patients with moderate-severe ACOP myocardial injury with NLR > 10.02 and T3 d sST2 > 43.50 μg/L, the occurrence of in-hospital MACE should be alert.
ABSTRACT
Objectives:To investigate the relationship between heart rate adjusted QT dispersion (QTcd) and soluble growth stimulating gene 2 protein (sST2) and the severity and prognosis of patients with acute carbon monoxide toxic heart disease.Methods:Retrospective analysis was performed on 135 patients with acute carbon monoxide toxic heart disease admitted to the Emergency Medical Department of our hospital from January 2017 to 2020. Blood sST2, creatine kinase isoenzyme (CK-MB) and troponin I(cTnI) concentrations were recorded at 3 h, 12 h, 2 d and 3 d immediately after admission.The patient was measured and calculated on the day of admission,2 d,3 d and QTcd at discharge.According to the toxicity of carbon monoxide in heart disease severity was divided into mild heart disease group (58 cases), moderate heart disease group (45 cases), severe heart disease group (32 cases), according to whether severe heart disease were divided into severe group (32 cases) and non severe group (103 cases), according to whether the patients death in patients with severe heart disease.Results:Thirty-two of the 135 patients had severe toxic heart disease, with an incidence of 23.7%.In the severe group, sST2, cTnI and CK-MB increased from 24 h and 2 d after admission, and the detected values were all higher than those of the non-severe group and the normal control group, with statistically significant differences ( P<0.05).Before treatment, there were statistically significant differences in sST2 and QTcd between the toxic group and the non-severe group and the normal control group ( P<0.05).After 2 d and 3 d poisoning, there were statistically significant differences between the two groups ( P<0.05). ROC curve analysis showed that the area under the sST2 curve was 0.726, 95% CI was 0.555-0.898, sensitivity was 56.3%, specificity was 94.1%, and truncation was 88.5 ng/mL.The area under the QTcd curve was 0.745, 95% CI was 0.602-0.889, sensitivity was 56.3%, specificity was 82.4%, and truncation value was 68.5 ms.The area under the combined detection curve was 0.939, 95% CI was 0.874-1.000, sensitivity was 81.3%, specificity was 91.2%. Conclusions:In patients with acute carbon monoxide toxic heart disease, the level of sST2 increased earlier than THAT of cTnI and CK-MB, and the combined observation of sST2 and QTcd can be used as an indicator for early prediction of acute carbon monoxide toxic heart disease and its severity.
ABSTRACT
Objective:To investigate the clinical significance of soluble growth stimulating expression gene 2 protein (sST2) combined with neutrophil/lymphocyte ratio (NLR) in the prediction of nosocomial cardiovascular adverse events in patients with acute carbon monoxide poisoning (ACOP) myocardial injury.Methods:Patients with ACOP myocardial injury from January 2017 to December 2019 in Emergency Ward and EICU of Harrson International Peace Hospital, Hebei Medical University were enrolled. NLR was calculated by routine blood examination on admission, and sST2 (T 0sST2, T 3dsST2) was detected by ELISA on admission and at 3 days after admission. According to the occurrence of cardiovascular adverse events, the patients were divided into the event group and the non-event group. Logistic regression was used to analyze the risk factors of in-hospital cardiovascular adverse events. ROC curve was used to analyze the value of sST2, NLR, sST2 and NLR combined in predicting the occurrence of in-hospital cardiovascular adverse events in patients with ACOP myocardial injury. Results:Totally 255 patients with ACOP myocardial injury were included in the final analysis. NLR was (13.38±4.33) in the event group and (9.57±4.22) in the non-event group, T 3dsST2 was (61.59±22.67) ng/mL in the event group and (40.52±13.14) ng/mL in the non-event group, with statistically significant differences (all P<0.01). T 0sST2 was (265.34±89.95) ng/mL in the event group and (242.43±93.09) ng/mL in the non-event group, with no statistically significant difference ( P=0.333). Logistic regression analysis showed that NLR ( OR=1.270, 95% CI: 1.125-1.434, P<0.01) and T 3dsST2 ( OR=1.082, 95% CI: 1.052-1.114, P<0.01) were independent risk factors for nosocomial cardiovascular adverse events in patients with ACOP myocardial injury. The optimal cutoff value of T 3dsST2 was 44.5 ng/mL, and of NLR was 12.08. The sensitivity and specificity of dual T 3dsST2 and NLR in predicting nosocomial cardiovascular adverse events was 79.3% and 82.7%, respectively (AUC 0.857, Youden index 0.620). Conclusions:T 3dsST2 and NLR are independent risk factors for the nosocomial cardiovascular adverse events in patients with ACOP myocardial injury. The predictive cutoff values are 44.5 ng/mL for T 3dsST2 and 12.08 for NLR. Combination of T 3dsST2 and NLR has a practical predictive value for nosocomial cardiovascular adverse events in patients with ACOP myocardial injury.
ABSTRACT
Objective:To investigate the value of combined detection of neutrophil gelatinase-associated lipocalin(NGAL), cystatin C(CysC)and heme oxygenase-1(HO-1)in the early diagnostic of acute kidney injury(AKI)caused by acute paraquat poisoning(APP)in elderly patients.Methods:One hundred and two elderly APP patients admitted to the emergency department of our hospital from May 2015 to June 2019 were assigned to the observation group, and 50 patients who took physical examinations served as the control group.The observation group was divided into the AKI sub-group(n=59)and the non-AKI sub-group(n=43)based on whether AKI occurred within 72 h of admission.Serum levels of NGAL, CysC, HO-1 and creatinine(Scr)were detected in all APP patients at 0 h(admission), 12 h, 24 h, 48 h and 72 h. Measurements of the same parameters were made on the day of physical examination for the control group.The correlations of serum levels of NGAL, CysC and HO-1 with the occurrence of AKI were analyzed.Relative operating characteristic curve(ROC)was drawn to analyze the diagnostic value of NGAL, CysC, HO-1 and the combination of the three for the early diagnosis of renal injury in APP patients.Results:Serum levels of NGAL, CysC, HO-1 and Scr at admission showed no significant difference between the AKI sub-group, non-AKI sub-group and control group( P>0.05). After admission, all the parameters showed an upward trend in the observation group.Serum levels of NGAL, CysC and HO-1 at 12 h after admission( P<0.05)and Scr levels at 72 h after admission( P<0.05)were significantly different between the AKI sub-group and the non-AKI sub-group.Correlation analysis showed that serum NGAL, CysC and HO-1 levels were positively correlated with the occurrence of AKI in APP patients at 12 h, 24 h, 48 h and 72 h after admission, with the best correlation at 48 h after admission(NGAL: r=0.203, 0.545, 0.707 and 0.560, P<0.05; CysC: r=0.242, 0.340, 0.754 and 0.467, P<0.05; HO-1: r=0.249, 0.536, 0.677 and 0.509, P<0.05). The area under ROC curve predicted by NGAL, CysC, HO-1, Scr and NGAL+ CysC+ HO-1 for AKI at 48 h after admission was 0.777, 0.718, 0.888, 0.602 and 0.969, respectively. Conclusions:Serum levels of NGAL, CysC and HO-1 are significantly elevated at 12 h after admission in elderly APP patients, and reach the peak at 48 h after admission.Each of them can give an earlier diagnosis for AKI than Scr, and the combination of the three provides a higher diagnostic accuracy for AKI.
ABSTRACT
Objective:To investigate the effect of clinical factors on the short-term prognosis of patients with acute carbon monoxide toxic heart disease.Methods:From October 2017 to December 2019, 92 patients with acute carbon monoxide poisoning (ACOP) and toxic heart disease admitted to the Department of Emergency of our hospital were enrolled in this study. The duration from poisoning to hospital admission, duration of coma, length of hospital stay, endotracheal intubation or not, admission to ICU ward or not, acute physiology and chronic health evaluation (APACHEⅡscore) at admission were recorded. The heart rate-corrected QT dispersion (QTcd) calculated based on electrocardiography results, as well as levels of serum trocalin I (cTnI) and creatine kinase isoenzyme (CK-MB) were recorded at admission, day 2, day 3, and hospital discharge. According to the diagnostic criteria of occupational cute toxic cardiopathy caused by chemicals, the patients were divided into three groups: 45 cases in the mild heart disease group (mild group), 35 cases in the moderate heart disease group (moderate group) and 12 cases in the severe heart disease group (severe group). The variables data of each group were presented as Mean±SD, and analyzed using one-way anova test. LSD- t test was used for pairwise comparison between the groups. Attributes data were compared using χ 2 comparisontest, and correlations were analyzed using Spearman correlation method and binary logistic regression analysis. Results:APACHE II score was significantly higher, and the durations of coma, and hospitalization time of severe heart disease group were significantly higher longer in the severe heart disease group than those ofin the mild and moderate groups, and the proportions of patients with early tracheal intubation to protect airway and admission in ICU ward were both significantly lower in the severe heart disease group than those ofin the mild and moderate moderate groups (all P < 0.05). The levels of CTnI and QTcd in each group increased immediately after admission, which was statistically different from that in the normal control group ( P < 0.05), while cTnI and QTcd at admission in the severe group were significantly higher than those in the mild and moderateother two groups ( P < 0.05). The levels of CK-MB in the severe group wereas significantly different from thoseat of the mild to and moderate groups at day 2 and day 3 after admission ( P < 0.05). The correlation between serum cTnI and APACHE II score at admission was R1 = 1.000 and R2 = 0.458. The correlation between QTcd and APACHE II score at admission was R1 = 1.000 and R2 = 0.765. Both of them were positively correlationsed with statistical difference ( P < 0.01). Conclusions:Patients with ACOP should admit to hospital as early as possible. For patients with severe hypoxia and no airway protection ability, an artificial airway should be established as soon as possible, and the patients should admit to the ICU at the early stage of poisoning to stabilize their condition. Changes of QTcd, serum cTnI, CK-MB and other related indicators should be monitored to detect cardiac injury in time and protect heart.
ABSTRACT
Objective:The predictive value of LCR and BIS monitoring for delayed encephalopathy in acute severe carbon monoxide poisoning.Methods:Ninety-four patients with acute severe carbon monoxide poisoning treated in the Harrison International Peace Hospital Affiliated to Hebei Medical University between January 2017 and March 2019 were selected. According to whether DEACMP occurred within 60 days after discharge, the patients were divided into the DEACMP group ( n=33) and good prognosis group ( n=61). LCR and BIS of the two groups at different time points were compared, and the correlation between LCR and BIS was analyzed. The predictive value of LCR, BIS and the combination of the two for DEACMP was analyzed by receiver operating characteristic (ROC) curve. Results:The LCR and BIS of the DEACMP group at day 1t, 3 and 5 were significantly lower than those of the good prognosis group ( P<0.05). Pearson correlation analysis showed that there was a positive correlation between BIS and LCR in the DEACMP group at day 1, 3 and 5 ( r=0.371, P<0.05). There was also a positive correlation between LCR and BIS in the good prognosis group at day 1, 3 and 5 ( r=0.373, P<0.05). ROC curve analysis showed that the areas under the curves of LCR, BIS and the combination of the two for predicting the occurrence of DEACMP in patients with ASCOP were 0.803 (95% CI: 0.707~0.897), 0.941 (95% CI: 0.886~0.997), and 0.949 (95% CI: 0.879~1.000), respectively. Conclusions:LCR combined with BIS is of high predictive value for the occurrence of DEACMP in patients with ASCOP.

A two-way factorial design was used to analyze the main effect of biofeedback on physical and biochemical parameters and the interaction of biofeedback and job stress.@*Results@#After 6 months of intervention, the patients in both the biofeedback group and the moderate group had significantly decreased waist circumference, body mass index, systolic blood pressure (SBP) , diastolic blood pressure (DBP) , and levels of triglyceride (TG) , total cholesterol, low-density lipoprotein cholesterol (LDL-C) , and fasting plasma glucose (FPG) and a significantly increased level of high-density lipoprotein cholesterol (HDL-C) (all P<0.05) ; the patients in both the health education group and the moderate group had significantly decreased SBP, DBP, and levels of TG, LDL-C, and FPG (P<0.05) . The factorial analysis of variance showed that there was a synergistic interaction between the intervention method and job stress level in SBP, DBP, TG, HDL-C, LDL-C, and FPG among MS patients (P<0.05) . The high group had significantly more improvements in all indices compared with the medium group and the moderate group (P<0.05) .@*Conclusion@#Biofeedback therapy can effectively improve blood pressure, blood lipids, and blood glucose in MS patients, and is more effective for patients with high job stress level.
ABSTRACT
Objective@#To investigate the relationship between neutrophil-to-lymphocyte ratio (NLR) and myocardial injury induced by acute carbon monoxide poisoning.@*Methods@#A retrospective analysis was performed on 214 patients with acute carbon monoxide poisoning who were admitted to Emergency Depart-ment of Harrison International Peace Hospital, Hebei Medical University, from 2015 to 2017. According to the diagnostic criteria for toxic heart disease and the level of cardiac troponin I (cTnI), a biomarker of cardiac injury, these patients were divided into myocardial injury group (n = 84) and non-myocardial injury group (n=130). The general information of age and sex, as well as routine blood test results and cardiac injury biomarkers on admission, were collected. NLR was calculated and compared between the two groups. The relationship between NLR and cTnI was analyzed. Logistic regression analysis was used to identify the influenc-ing factors for myocardial injury induced by acute carbon monoxide poisoning. The receiver operating charac-teristic curve was used to evaluate the predictive value of NLR on admission for myocardial injury induced by acute carbon monoxide poisoning.@*Results@#There were significant differences between two groups in male patients, the history of smoking, white blood cell count (WBC), NLR, creatine kinase-MB, and lactate dehydro-genase(P<0.01). In the myocardial injury group, NLR was positively correlated with cTnI (r=0.295, P<0.01). The multivariate logistic regression analysis showed that NLR (odds ratio OR=1.079, 95% confidence inter-val CI: 1.017~1.144, P<0.01), WBC (OR=1.216, 95% CI: 1.098~1.346, P<0.01), and male sex (OR = 2.693, 95% CI: 1.045~6.939, P= 0.05) were independent risk factors for myocardial injury induced by acute carbon monoxide poisoning. In predicting myocardial injury induced by acute carbon monoxide poisoning, NLR on admission had a sensitivity of 85.7% and a specificity of 45.4% at the optimal cut-off value of 4.83.@*Conclusion@#Increased NLR on admission has a certain predictive value for myocardial injury induced by acute carbon monoxide poisoning.

ABSTRACT
Objective To investigate the clinical values of continuous hemoperfusion on the level of inter-leukin-18(IL-18)and prognosis in patients with acute paraquat poisoning(APP). Methods A total of 112 pa-tients with APP treated in our hospital from Jun 2013 to Jul 2017 were divided into two groups:control group(56 cases,routine drug and single hemoperfusion)and therapy group(56 cases,treated by continuous hemoperfusion based on control group).All APP patients were treated with continuous veno venous hemofiltration(CVVH)at 24 hours after treatment.Within admission 24 hours,3 days and 7 days after treatment,IL-18,lactic acid(Lac),ar-terial oxygen partial pressure(PaO2),alanine aminotransferase(ALT),creatinine(Cr)and creatine kinase(CK-MB)of patients were detected,28-day survival was recorded.Pearson correlation test was used to analyze the corre-lation between IL-18 in patients with APP and the survival rate. Results In admission,there were no differences in the levels of IL-18,Lac,PaO2,ALT,Cr and CK-MB between the two groups(P>0.05).At 3 days after treat-ment,the levels of IL-18,Lac,ALT,Cr and CK-MB were higher than those before treatment,and the therapy group was lower than the control group,while PaO2was lower than those before treatment,and the therapy group was higher than the control group(P<0.05);At 7 days after treatment,the two groups both had lower levels of IL-18,Lac,ALT,Cr and CK-MB than those after 3 days treatment,and the therapy group was lower than the con-trol group,while PaO2was lower than those after 3 days treatment,and the therapy group was higher than the con-trol group(P<0.05);There were 39 deaths in the therapy group and 49 deaths in the control group,the therapy group had a lower 28-day mortality rate than control group,the difference was statistically significant(69.64% vs 87.50%,χ2=5.303,P=0.021). The level of serum IL-18 in patients with APP was negatively correlated with the survival rate(r =-0.209,P = 0.027).Conclusions Therapeutic effect of continuous hemoperfusion in APP pa-tients is superior to single hemoperfusion. It could decrease the levels of IL-18,Lac,ALT,Cr and CK-MB,im-prove PaO2 and reduce the mortality rate of patients.The clinical curative effect is distinct.
ABSTRACT
Objective@#To investigate the dynamic change in cerebral oxygen utilization coefficient (O2UCc) in the early stage of acute severe carbon monoxide poisoning (ASCMP) and its value in predicting delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) .@*Methods@#A prospective observational study was conducted for patients with ASCMP who were admitted to our hospital from November 2013 to March 2016, and their baseline features and physiological parameters were recorded. Observation ended at two months after acute poisoning; according to the presence or absence of DEACMP, the patients were divided into DEACMP group with 21 patients and non-DEACMP group with 64 patients. The change in O2UCc was monitored on admission and at 6, 24, 48, and 72 hours. Spearman correlation was used to investigate the correlation between O2UCc and Acute Physiology and Chronic Health Evaluation II (APACHE II) score, and the receiver operating characteristic (ROC) curve was used to evaluate the accuracy of O2UCc in predicting DEACMP.@*Results@#Both groups had a significant increase in O2UCc on admission, and the DEACMP group had a significantly greater increase than the non-DEACMP group (52.57%±9.30% vs 41.46±%6.37%, P<0.05) . Then both groups tended to have a reduction in O2UCc, and the DEACMP group had a significantly higher O2UCc than the non-DEACMP group at 6, 24, and 48 hours (47.40%±7.92%, 39.38%±8.01%, and 32.29%±6.31% vs 34.51%±7.89%, 28.79%±5.4%, and 27.72%±5.46%, P<0.05) . On admission and at 6, 24, and 48 hours, O2UCc was positively correlated with APACHE II score (r=0.304, 0.398, 0.426, and 0.300, P=0.005, 0.000, 0.000, and 0.005) . The ROC curve showed that O2UCc had a value in predicting DEACMP on admission and at 6, 24, and 48 hours, and 6-hour O2UCc had the highest predictive value with an area under the ROC curve of 0.870 (95% confidence interval 0.794-0.947, P<0.05) .@*Conclusion@#The dynamic change in O2UCc has a reference value in early identification of DEACMP, and O2UCc can be used as an important reference index for predicting DEACMP.

ABSTRACT
Objective@#To observe the effects of Ginaton on blood nitric oxide (NO) and nitric oxide synthase (NOS) in patients with delayed encephalopathy after acute carbon monoxide poisoning (DEACMP).@*Methods@#A total of 116 patients with DEACMP who were treated in Emergency Department of Harrison International Peace Hospital Affiliated to Hebei Medical University from January 2012 to April 2016 were enrolled and ran-domly divided into control group and treatment group using a random number table, with 58 patients in each group. The patients in the control group were given conventional treatment including hyperbaric oxygen, preven-tion and treatment of cerebral edema, and promotion of brain cell metabolism, and those in the treatment group were given Ginaton in addition to the conventional treatment. The course of treatment was 2 weeks for both groups. The levels of neuron-specific enolase (NSE) , NO, NOS, and inducible nitric oxide synthase (iNOS) were measured before treatment and at 2 weeks after treatment, and the change in Mini-Mental State Examina-tion (MMSE) score and clinical outcome were observed in both groups. The correlation between the blood NO level on admission and the MMSE score was analyzed.@*Results@#There was a significant difference in the overall response rate between the treatment group and the control group (81.03% vs 62.07%, χ2 = 5.124, P=0.024). Be-fore treatment, there were no significant differences in the levels of NO and NSE, the activity of NOS and iN-OS, and MMSE score between the two groups (P>0.05). After treatment, both groups showed reductions in the levels of NO and NSE and the activity of NOS and iNOS, but the treatment group had significantly greater reduc-tions compared with the control group (P<0.05). Both groups showed a significant increase in the MMSE score after treatment, while the treatment group had a significantly greater increase compared with the control group (P<0.05). In the patients with DEACMP, the blood NO level on admission was negatively correlated with the MMSE score (r=-0.268, P=0.004).@*Conclusion@#In the treatment of patients with DEACMP, Ginaton can effectively reduce the levels of NO and NSE and the activity of NOS and iNOS, increase the MMSE score, and promote the recovery of neurological function.
