ABSTRACT

Objective:To explore the risk factors of intensive care unit acquired weakness (ICUAW) in patients with sepsis, and to evaluate the predictive value of each risk factor for ICUAW.Methods:A case control study was conducted, 60 septic patients admitted to the intensive care unit (ICU) of Henan Provincial People's Hospital from October 20, 2020 to February 20, 2021 were enrolled. The patients were divided into two groups: sepsis ICUAW group and sepsis non-ICUAW group. The data of gender, age, body mass index (BMI), acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, complications, mechanical ventilation, duration of ICUAW, length of stay in ICU, fasting blood glucose, blood lactic acid (Lac), procalcitonin (PCT), C-reactive protein (CRP), sequential organ failure assessment (SOFA) score, outcome, antimicrobial agent, glucocorticoid, sedatives and analgesics drugs and vasoactive drugs were collected. Risk factors were screened by univariate Logistic regression analysis, and odds ratio ( OR) was adjusted by multivariate binary logistic regression, P < 0.05 was considered as independent risk factors. Finally, the receiver operating characteristic curve (ROC curve) was drawn to analyze the predictive value of independent risk factors. Results:The APACHEⅡ score of the sepsis ICUAW group was significantly higher than that of the sepsis non-ICUAW group (23.05±8.17 vs. 15.33±4.89, P < 0.05), the total length of stay in the ICU was significantly longer than that of the sepsis non-ICUAW group (days: 15.1±9.2 vs. 8.5±3.4, P < 0.05), the improvement rate of patients was significantly lower than that of the sepsis non-ICUAW group [45.0% (9/20) vs. 95.0% (38/40), P < 0.05]. After univariate Logistic regression and multicollinearity test analysis, 7 factors including APACHEⅡ score, average SOFA score, blood lactic acid, proportion of mechanical ventilation, sedatives and analgesics drugs, type of antibiotics and type of vasoactive drugs were included in the binary Logistic regression model [ OR: 1.21, 2.05, 2.26, 0.21, 1.54, 2.07, 1.38, 95% confidence interval (95% CI): 1.09-1.35, 1.42-2.94, 1.12-4.57, 0.05-0.66, 1.03-2.29, 1.27-3.37, 0.96-2.00, all P < 0.05]. Hosmer-Lemchaw test P = 0.901, and the correct percentage of prediction was 85%, indicating good model fit. Multivariate binary Logistic regression analysis showed that APACHEⅡ score and average SOFA score were independent risk factors for the occurrence of ICUAW in septic patients (APACHEⅡscore: OR = 1.17, 95% CI was 1.004-1.376, P = 0.044; average SOFA score: OR = 1.86, 95% CI was 1.157-2.981, P = 0.01). ROC curve analysis showed that the mean value of APACHEⅡ score, average SOFA score and their combined detection had a certain predictive value for the occurrence of ICUAW in sepsis patients, areas under ROC curve (AUC) were 0.787, 0.881, 0.905, 95% CI was 0.646-0.928, 0.791-0.972, 0.828-0.982, all P < 0.05. When the cut-off value was 19.500, 6.225, 0.375, the sensitivity was 75%, 90%, 90%, and the specificity were 80%, 80%, 85%, respectively. Conclusion:APACHEⅡ score and average SOFA score can be used as independent risk factors for the occurrence of ICUAW in sepsis, and their combined predictive value is better than that of individual index.

ABSTRACT

Objective:To assess the application of extracorporeal membrane oxygenation (ECMO) regional treatment pattern in patients with severe cardiopulmonary diseases.Methods:A retrospective analysis was conducted. Patients with severe cardiopulmonary disease who were transferred to Henan Provincial People's Hospital after ECMO treatment in cooperative hospitals were selected. The patients who received regular ECMO treatment from June 2017 to May 2018 were enrolled as the control group, and the patients who received ECMO regional treatment from June 2018 to May 2019 were selected as the observation group. The ECMO regional treatment pattern referred to implement a referral program for critical patients in primary hospitals, which mainly included the establishment of ECMO regional cooperative treatment network and ECMO referral team, the formulation of ECMO referral management standards, and the promotion of the merging of high-quality medical resources. Time of establishment of ECMO, ECMO regional treatment satisfaction, and the incidence of adverse events were also compared.Results:There were 27 patients enrolled in the control group and 64 patients in the observation group. There were no significant differences in gender, age, body mass index (BMI), ECMO mode, hypertension or coronary heart disease history between the two groups. Compared with the control group, the time for establishment of ECMO in the observation group was significantly shorter (minutes: 38.10±17.19 vs. 54.67±41.30, t = 2.715, P = 0.008), the ECMO treatment satisfaction of the observation group was also significantly higher than that of the control group (98.4% vs. 88.9%, χ 2 = 4.120, P = 0.042), and the incidence of ECMO referral adverse events was significantly lower than that of the control group (6.25% vs. 25.93%, χ 2 = 6.918, P = 0.009). Conclusion:The ECMO regional collaborative pattern in patients with severe cardiopulmonary diseases can shorten the time for establishment of ECMO, improve the satisfaction of ECMO treatment, and reduce the incidence of adverse events in ECMO referral.

ABSTRACT

Objective@#To explore the usability of regional saturation of cerebral oxygenation (rScO2) combined with percentage of α variability (PAV) in predicting brain function prognosis in patients with traumatic brain injury (TBI).@*Methods@#A retrospective analysis was conducted. The clinical data of patients with TBI who were monitored rScO2 and bedside quantitative electroencephalogram (qEEG) admitted to intensive care unit (ICU) of Henan Provincial People's Hospital from August 2018 to July 2019 were collected. The rScO2, PAV, and Glasgow coma scale (GCS) score were recorded within 72 hours after the TBI. The primary prognostic indicator was the 3-month Glasgow outcome score (GOS) score. The differences between the two groups of poor prognosis of brain function (GOS score 1-3) and good prognosis (GOS score 4-5) were compared. Binary multivariate Logistic regression analysis was used to analyze the correlation between rScO2, PAV, GCS score and the prognosis of brain function in patients with TBI. In addition, receiver operating characteristic (ROC) curve was plotted to analyze the predicting value of rScO2 and PAV only or combination for prognosis of brain function.@*Results@#A total of 42 patients with TBI were enrolled in the study, with rScO2≥0.60 (grade Ⅰ) in 14 patients, 0.50≤rScO2 < 0.60 (grade Ⅱ) in 16 patients, and rScO2 < 0.50 (grade Ⅲ) in 12 patients. PAV 3-4 scores (grade Ⅰ) were detected in 16 patients, 2 scores (grade Ⅱ) in 17 patients, and 1 score (grade Ⅲ) in 9 patients. GCS score 9-14 (grade Ⅰ) were observed in 13 patients, 4-8 (grade Ⅱ) in 23 patients, and 3 (grade Ⅲ) in 6 patients; 18 patients had poor prognosis and 24 had good one. The rScO2, PAV and GCS scores of the poor-prognosis group were significantly higher than those in the good-prognosis group [rScO2 with grade Ⅲ: 55.6% (10/18) vs. 8.3% (2/24), PAV with grade Ⅲ: 38.9% (7/18) vs. 8.4% (2/24), GCS score with grade Ⅲ: 27.7% (5/18) vs. 4.1% (1/24)] with significant differences (all P < 0.05). There was no significant difference in other general data including gender, age, total length of hospital stay or acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score between the two groups. Binary multivariate Logistic regression analysis showed that rScO2 and PAV were independent risk factors for prognosis of brain in patients with TBI [rScO2: odds ratio (OR) = 4.656, 95% confidence interval (95%CI) was 1.071-20.233, P = 0.040; PAV: OR = 3.525, 95%CI was 1.044-11.906, P = 0.042]. ROC curve analysis showed that both of rScO2 and PAV had predictive value for the prognosis of brain function in patients with TBI (AUC was 0.796 and 0.780, respectively, both P < 0.01), and rScO2 combined with PAV had higher predictive value with the AUC of 0.851 (P < 0.01) than rScO2 or PAV alone, the sensitivity was 94.4% and the specificity was 62.5%.@*Conclusions@#rScO2 and PAV were associated with early brain function prognosis in patients with TBI. The combination of two monitoring indicators can reliably assess the prognosis of brain function in patients with TBI.

ABSTRACT

Objective To explore the predictive value of heparin-binding protein (HBP) combined with sequential organ failure assessment (SOFA) score in patients with septic shock. Methods Seventy-eight patients with sepsis admitted to intensive care unit (ICU) of Henan Provincial People's Hospital from December 2016 to May 2017 were enrolled. Thirty healthy persons were enrolled as controls. The patient's gender, age, length of ICU stay, and blood culture results, white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT), blood lactate (Lac), HBP, SOFA score, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, organ failure and vasoactive agents usage within 24 hours of admission were recorded. The differences in the above indicators between the groups were compared, and the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of HBP, SOFA score and their combination in patients with septic shock. Results All patients were enrolled in the final analysis, including 64 with sepsis and 14 with septic shock. Compared with the sepsis group, the proportion of patients with septic shock who were positive for blood culture, organ failure, and vasoactive agents was higher [57.1% (8/14) vs. 7.8% (5/64), 100.0% (14/14) vs. 65.6% (42/64), 100.0% (14/14) vs. 18.8% (12/64), all P < 0.01], SOFA and APACHEⅡscores were also higher (SOFA: 8.93±4.16 vs. 5.89±2.68, APACHEⅡ: 22.29±4.89 vs. 15.28±5.14, both P < 0.01);however, there was no significant difference in gender, age or length of ICU stay between the two groups. Compared with the healthy control group, HBP, PCT, CRP and Lac levels were significantly increased in the sepsis group and the septic shock group. HBP in the septic shock group was significantly higher than that in the sepsis group (μg/L: 120.33±43.49 vs. 68.95±54.15, P < 0.05), but there was no significant difference in PCT, CRP or Lac between septic shock group and sepsis group [PCT (μg/L): 1.42 (0.47, 46.00) vs. 0.71 (0.19, 4.50), CRP (mg/L): 102.90±78.12 vs. 102.07±72.15, Lac (mmol/L): 1.81 (1.14, 3.65) vs. 1.59 (1.17, 2.24), all P > 0.05]. It was shown by ROC curve analysis that the area under the ROC curve (AUC) of SOFA score for predicting septic shock was 0.715 [95% confidence interval (95%CI) = 0.540-0.890, P = 0.012], and when the optimal cut-off value was 7.5, the sensitivity was 64.3%, the specificity was 76.6%. The AUC of HBP was 0.814 (95%CI = 0.714-0.913, P < 0.001), and when the optimal cut-off value was 89.43 μg/L, the sensitivity was 78.6%, the specificity was 76.6%; when the two were combined, the AUC was 0.829 (95%CI = 0.724-0.935, P < 0.001), the sensitivity was 92.9%, and the specificity was 61.9%. Conclusion HBP can be used as a biological indicator for predicting septic shock, and the accuracy of predicting septic shock can be improved with the combination of SOFA score.

ABSTRACT

In recent years, more and more attention has been paid to the occurrence and harm of delirium, and intensive care unit (ICU) delirium has become a hot issue. The incidence of delirium in ICU patients is much higher than that of general wards, all kinds of complications caused by delirium and increased mortality should win enough attention of the clinicians. There is no uniform standard for the diagnosis and evaluation of ICU delirium, which is a major problem that affects clinicians in the early diagnosis and assessment of prognosis. By reviewing the domestic and international researches of ICU delirium, the latest progress of diagnostic and assessment instruments for delirium in ICU is stated, which provides an important basis for the early identification and diagnosis of delirium in ICU.

ABSTRACT

Objective@#To verify the accuracy of oxygen concentration (FiO2) of modified oxygen treatment with Venturi and humidity system.@*Methods@#Patients just after ventilator weaning and before the removal of tracheal intubation/tracheotomy tube, who admitted to the intensive care unit (ICU) of Henan Provincial People's Hospital from May 1st to December 15th in 2017, were enrolled. All patients were given a modified oxygen treatment with Venturi and humidity system, and the oxygen flow rate (Flow) of the Venturi device and the oretical value of FiO2 were adjusted according to the patient's condition. Patients were divided into five groups based on doctor's orders: Flow 3 L/min FiO2 0.24, Flow 3 L/min FiO2 0.26, Flow 6 L/min FiO2 0.28, Flow 6 L/min FiO2 0.30, Flow 9 L/min FiO2 0.35. The value of FiO2 at the inhalation end of patients of each group was measured by TSI airflow analyzer, and the consistency between the measured value of FiO2 at the inhalation end and the FiO2 marked value of Venturi was compared and analyzed.@*Results@#When the FiO2 theoretical value of Venturi were adjusted to 0.24, 0.26, 0.28, 0.30, and 0.35, the measured values of FiO2 at the inhalation end of patients were 0.38±0.05, 0.38±0.05, 0.40±0.04, 0.41±0.04, and 0.77±0.11, respectively, which were all significantly higher than the theoretical value of FiO2 (all P < 0.01). The difference between the measured value of FiO2 at the inhalation side and the FiO2 value of the Venturi annotated and the difference rate were both "V"-shaped, both of which decreased with the increase in theoretical value of FiO2 to a Flow of 9 L/min and a theoretical value of FiO2 0.35, the accuracy was the worst, with the FiO2 difference of 0.42±0.11, and the FiO2 difference rate of (121.6±36.5)%.@*Conclusion@#There is a difference between the measured value and the theoretical value of FiO2 at the inhalation end of the modified Venturi oxygen therapy humidification system, which needs to be paid attention to during clinical oxygen therapy.

ABSTRACT

Objective To investigate the protective effect of hesperidin on severe acute pancreatitis (SAP) in rats and its related mechanism.Methods Sixty male Sprague-Dawley (SD) rats were randomly divided into five groups (n = 12 in each group): sham group, SAP model group, dexamethasone group (5 mg/kg), low and high dose of hesperidin groups (10 mg/kg and 20 mg/kg). SAP rats were administered a retrograde infusion of 3.5% sodium taurocholate solution into the biliopancreatic duct after laparotomy. Sham rats were administered with equivalent saline. The treatment was intravenously injected 5 minutes after operation through femoral vein. After 24 hours, the survival of animals was observed, the level of serum amylase, the volume of ascites and the relative specific gravity of the pancreas were measured; the pathological changes of pancreatic tissue were observed by Hematoxylin-eosin (HE) staining; the levels of serum and pancreatic tissue interleukin (IL-1β, IL-6) and tumor necrosis factor-α (TNF-α) were detected by enzyme linked immunosorbent assay (ELISA); the expression of Toll-like receptor 4 (TLR4), the phosphorylation of IL-1 receptor associated kinase (IRAK1) and nuclear factor-κB (NF-κB) were detected by Western Blot.Results Compared with SAP model group, the 24-hour survival rate were increased in low and high dose of hesperidin groups (83.3%, 100% vs. 58.3%), the volume of ascites were reduced (mL: 7.36±0.91, 6.10±1.02 vs. 13.82±2.06), the levels of serum amylase were reduced (U/L: 1081.48±78.23, 1048.58±49.97 vs. 1990.37±127.27), the relative specific gravity of the pancreas were reduced [(7.52±1.02)%, (5.59±0.96)% vs. (11.22±0.96)%], and the pathological damage of pancreatic tissue were reduced; the levels of serum and pancreatic tissue inflammatory factors were reduced in high dose hesperidin group [serum IL-1β (ng/L): 68.08±10.49 vs. 130.30±23.35, IL-6 (ng/L): 63.88±10.47 vs. 158.41±21.38, TNF-α(ng/L): 10.42±1.49 vs. 18.16±2.01; pancreas IL-1β (pg/μg): 13.87±1.84 vs. 20.08±1.66, IL-6 (pg/μg): 21.90±3.12vs. 38.13±3.57, TNF-α (pg/μg): 1.88±0.20 vs. 4.26±0.58]; the expression of TLR4, and the phosphorylation levels of IRAK1 and NF-κB were decreased in low and high dose of hesperidin groups (the sham operation group was 100, TLR4/β-actin: 91.9±15.6, 83.7±11.2 vs. 168.5±9.0, p-IRAK1/IRAK1: 117.4±7.6, 104.7±11.5 vs. 173.5±15.8, p-NF-κB p65/NF-κB p65: 119.9±9.3, 105.8±12.6 vs. 174.1±13.0), with statistically significant differences (allP < 0.05). The effects of dexamethasone were similar to that of high dose of hesperidin.Conclusions Hesperidin could significantly protect SAP rats, and this protection was related to the inhibition of TLR4/IRAK1/NF-κB signaling pathway, and to the reduction of pro-inflammatory cytokine expressions. The effect of high dose hesperidin (20 mg/kg) was more significant.

ABSTRACT

Objective To explore the characteristic of early evaluation of patients with amplitude-integrated electroencephalogram (aEEG) on brain function prognosis after cardiopulmonary cerebral resuscitation (CPCR). Methods A retrospective analysis of the clinical data of patients with adult CPCR in intensive care unit (ICU) of Henan Provincial People's Hospital from March 2016 to March 2017 was performed. The length of stay, recovery time, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, aEEG and Glasgow coma scale (GCS) within 72 hours were recorded. The main clinical outcome was the prognosis of brain function (Glasgow-Pittsburgh cerebral performance category, CPC) in patients with CPCR after 3 months. Relationship between aEEG and GCS and their correlation with brain function prognosis was analyzed by Spearman rank correlation analysis. The effects of aEEG and GCS on prognosis of brain function were evaluated by Logistic regression analysis. The predictive ability of aEEG and GCS for brain function prognosis was evaluated by receiver operating characteristic (ROC) curve.Results A total of 31 patients with CPCR were enrolled, with 18 males and 13 females; mean age was (41.84±16.96) years old; recovery time average was (19.42±10.79) minutes; the length of stay was (14.84±10.86) days; APACHE Ⅱ score 19.29±6.42; aEEG grade Ⅰ(normal amplitude) in 7 cases, grade Ⅱ (mild to moderate abnormal amplitude) in 13 cases, grade Ⅲ (severe abnormal amplitude) in 11 cases; GCS grade Ⅰ (9-14 scores) in 7 cases, grade Ⅱ (4-8 scores) in 14 cases, grade Ⅲ (3 scores) in 10 cases; 19 survivals, 12 deaths; the prognosis of brain function was good (CPC 1-2) in 8 cases, and the prognosis of brain function was poor (CPC 3-5) in 23 cases. There was no significant difference in age, gender, recovery time, length of stay and APACHE Ⅱ score between two groups with different brain function prognosis, while aEEG grade and GCS grade were significantly different. Cochran-Armitage trend test showed that the higher the grade of aEEG and GCS, the worse the prognosis of CPCR patients (bothP-trend < 0.01). With the increase in GCS classification, the classification of aEEG was also increasing (r = 0.6206,P = 0.0003). Both aEEG and GCS were positively correlated with the prognosis of brain function (r1 = 0.7796,P1 < 0.0001;r2 = 0.7021,P2 < 0.0001). Univariate Logistic regression analysis showed that aEEG and GCS had significant effect on early brain function prognosis [aEEG: odds ratio (OR) = 37.234, 95%confidence interval (95%CI) = 3.168-437.652,P = 0.004, GCS:OR = 12.333, 95%CI = 1.992-76.352,P = 0.007]; after adjusting for aEEG and GCS, only aEEG had significant effect on the early prognosis of brain function (OR = 26.932, 95%CI = 1.729-419.471,P = 0.019). The ROC curve analysis showed that in the evaluation of the prognosis of CPCR patients with brain function, the area under ROC curve (AUC) of aEEG was 0.913, when the cut-off value of aEEG was 1.5, the sensitivity was 95.7% and the specificity was 75.0%. The AUC of GCS was 0.851, the best cut-off value was 1.5, the sensitivity was 91.3% and the specificity was 62.5%.Conclusion aEEG and GCS scores have a good correlation in the evaluation of brain function prognosis in patients with CPCR, the accuracy of aEEG in the early evaluation of the prognosis of patients with CPCR is higher than the GCS score.

SAP rats were administered a retrograde infusion of 3.5% sodium taurocholate solution into the biliopancreatic duct after laparotomy. Sham rats were administered with equivalent saline. The treatment was intravenously injected 5 minutes after operation through femoral vein. After 24 hours, the survival of animals was observed, the level of serum amylase, the volume of ascites and the relative specific gravity of the pancreas were measured; the pathological changes of pancreatic tissue were observed by Hematoxylin-eosin (HE) staining; the levels of serum and pancreatic tissue interleukin (IL-1β, IL-6) and tumor necrosis factor-α (TNF-α) were detected by enzyme linked immunosorbent assay (ELISA); the expression of Toll-like receptor 4 (TLR4), the phosphorylation of IL-1 receptor associated kinase (IRAK1) and nuclear factor-κB (NF-κB) were detected by Western Blot.Results Compared with SAP model group, the 24-hour survival rate were increased in low and high dose of hesperidin groups (83.3%, 100% vs. 58.3%), the volume of ascites were reduced (mL: 7.36±0.91, 6.10±1.02 vs. 13.82±2.06), the levels of serum amylase were reduced (U/L: 1081.48±78.23, 1048.58±49.97 vs. 1990.37±127.27), the relative specific gravity of the pancreas were reduced [(7.52±1.02)%, (5.59±0.96)% vs. (11.22±0.96)%], and the pathological damage of pancreatic tissue were reduced; the levels of serum and pancreatic tissue inflammatory factors were reduced in high dose hesperidin group [serum IL-1β (ng/L): 68.08±10.49 vs. 130.30±23.35, IL-6 (ng/L): 63.88±10.47 vs. 158.41±21.38, TNF-α(ng/L): 10.42±1.49 vs. 18.16±2.01; pancreas IL-1β (pg/μg): 13.87±1.84 vs. 20.08±1.66, IL-6 (pg/μg): 21.90±3.12vs. 38.13±3.57, TNF-α (pg/μg): 1.88±0.20 vs. 4.26±0.58]; the expression of TLR4, and the phosphorylation levels of IRAK1 and NF-κB were decreased in low and high dose of hesperidin groups (the sham operation group was 100, TLR4/β-actin: 91.9±15.6, 83.7±11.2 vs. 168.5±9.0, p-IRAK1/IRAK1: 117.4±7.6, 104.7±11.5 vs. 173.5±15.8, p-NF-κB p65/NF-κB p65: 119.9±9.3, 105.8±12.6 vs. 174.1±13.0), with statistically significant differences (allP < 0.05). The effects of dexamethasone were similar to that of high dose of hesperidin.Conclusions Hesperidin could significantly protect SAP rats, and this protection was related to the inhibition of TLR4/IRAK1/NF-κB signaling pathway, and to the reduction of pro-inflammatory cytokine expressions. The effect of high dose hesperidin (20 mg/kg) was more significant.

ABSTRACT

Objective To explore the characteristic of early evaluation of patients with amplitude-integrated electroencephalogram (aEEG) on brain function prognosis after cardiopulmonary cerebral resuscitation (CPCR). Methods A retrospective analysis of the clinical data of patients with adult CPCR in intensive care unit (ICU) of Henan Provincial People's Hospital from March 2016 to March 2017 was performed. The length of stay, recovery time, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, aEEG and Glasgow coma scale (GCS) within 72 hours were recorded. The main clinical outcome was the prognosis of brain function (Glasgow-Pittsburgh cerebral performance category, CPC) in patients with CPCR after 3 months. Relationship between aEEG and GCS and their correlation with brain function prognosis was analyzed by Spearman rank correlation analysis. The effects of aEEG and GCS on prognosis of brain function were evaluated by Logistic regression analysis. The predictive ability of aEEG and GCS for brain function prognosis was evaluated by receiver operating characteristic (ROC) curve.Results A total of 31 patients with CPCR were enrolled, with 18 males and 13 females; mean age was (41.84±16.96) years old; recovery time average was (19.42±10.79) minutes; the length of stay was (14.84±10.86) days; APACHE Ⅱ score 19.29±6.42; aEEG grade Ⅰ(normal amplitude) in 7 cases, grade Ⅱ (mild to moderate abnormal amplitude) in 13 cases, grade Ⅲ (severe abnormal amplitude) in 11 cases; GCS grade Ⅰ (9-14 scores) in 7 cases, grade Ⅱ (4-8 scores) in 14 cases, grade Ⅲ (3 scores) in 10 cases; 19 survivals, 12 deaths; the prognosis of brain function was good (CPC 1-2) in 8 cases, and the prognosis of brain function was poor (CPC 3-5) in 23 cases. There was no significant difference in age, gender, recovery time, length of stay and APACHE Ⅱ score between two groups with different brain function prognosis, while aEEG grade and GCS grade were significantly different. Cochran-Armitage trend test showed that the higher the grade of aEEG and GCS, the worse the prognosis of CPCR patients (bothP-trend < 0.01). With the increase in GCS classification, the classification of aEEG was also increasing (r = 0.6206,P = 0.0003). Both aEEG and GCS were positively correlated with the prognosis of brain function (r1 = 0.7796,P1 < 0.0001;r2 = 0.7021,P2 < 0.0001). Univariate Logistic regression analysis showed that aEEG and GCS had significant effect on early brain function prognosis [aEEG: odds ratio (OR) = 37.234, 95%confidence interval (95%CI) = 3.168-437.652,P = 0.004, GCS:OR = 12.333, 95%CI = 1.992-76.352,P = 0.007]; after adjusting for aEEG and GCS, only aEEG had significant effect on the early prognosis of brain function (OR = 26.932, 95%CI = 1.729-419.471,P = 0.019). The ROC curve analysis showed that in the evaluation of the prognosis of CPCR patients with brain function, the area under ROC curve (AUC) of aEEG was 0.913, when the cut-off value of aEEG was 1.5, the sensitivity was 95.7% and the specificity was 75.0%. The AUC of GCS was 0.851, the best cut-off value was 1.5, the sensitivity was 91.3% and the specificity was 62.5%.Conclusion aEEG and GCS scores have a good correlation in the evaluation of brain function prognosis in patients with CPCR, the accuracy of aEEG in the early evaluation of the prognosis of patients with CPCR is higher than the GCS score.

ABSTRACT

Objective To investigate the influence of simvastatin treatment on Toll-like receptor 4 (TLR4) in monocytes of peripheral blood in patients with sepsis and severe sepsis and its significance. Methods A prospective randomized controlled trial was conducted. 106 patients with sepsis and 92 patients with severe sepsis admitted to Department of Critical Care Medicine of Henan Provincial People's Hospital from August 2013 to June 2015 were enrolled. These two groups of patients were randomized into conventional treatment group and simvastatin group. All patients received treatment according to the 2012 International Sepsis Treatment Guidelines, including anti-infection drugs, nutritional support, and palliative treatment, and the patients with severe sepsis were given early goal-directed therapy (EGDT). The patients in simvastatin group received simvastatin 40 mg daily orally for at least 15 days. The peripheral blood was collected and the monocytes were isolated at 1, 5, 10, 15 days after intensive care unit (ICU) admission. TLR4 expression on the surface of TLR4/CD14+ double positive monocytes was determined by flow cytometry, and adverse reaction was observed during treatment. Results TLR4 expression on the surface of monocytes showed a tendency of decreasing with prolongation of simvastatin treatment in the simvastatin group in patients with sepsis (n = 59) or severe sepsis (n = 54). However, in patients with sepsis, TLR4 level was significantly decreased from 10 days in simvastatin group as compared with that of conventional therapy group (n = 47), and it was decreased up to 15 days [mean fluorescence intensity (MFI): 21 (19, 28) vs. 27 (25, 33) at 10 days, Z = 2.198, P = 0.021; 16 (15, 21) vs. 26 (23, 34) at 15 days, Z = 4.611, P = 0.002]. In patients with severe sepsis, there was no significant difference in TLR4 level at different time points between simvastatin group and conventional treatment group (n = 38) [MFI: 55 (52, 63) vs. 56 (48, 65) at 1 day, Z = 0.313, P = 0.692; 47 (42, 56) vs. 49 (41, 58) at 5 days, Z = 0.827, P = 0.533; 40 (35, 42) vs. 42 (37, 45) at 10 days, Z = 1.012, P = 0.301; 33 (30, 38) vs. 38 (35, 41) at 15 days, Z = 0.539, P = 0.571]. No adverse reaction related with simvastatin was found during treatment in patients with sepsis or severe sepsis. Conclusions Statins could significantly down-regulate the TLR4 expression on peripheral blood monocytes in septic patients, while it showed no significant influence on TLR4 expression in patients with severe sepsis. A different effect of statins on TLR4 expression and the downstream inflammation process in sepsis and severe sepsis patients might partially explain the discrepancy in previous reports about the therapeutic effect of statins therapy in sepsis and severe sepsis patients.

ABSTRACT

ObjectiveTo study the effect of anticoagulant therapy with low molecular weight heparin (LMWH) on coagulation and inflammation markers in sepsis patients.Methods A prospective randomized controlled trial was conducted. Sixty sepsis patients admitted to intensive care unit (ICU) of Zhengzhou University People's Hospital from March 2012 to May 2014 were divided into control group and observation group, with 30 cases in each group. The observations were begun as soon as the diagnosis of sepsis was established, and the observation time was 7 days. All sepsis patients were treated according to the 2008 international sepsis treatment guidelines. Every patient in the observation group was subcutaneously injected with LMWH 0.6 mL on the first day of ICU admission, twice a day for 7 days. The blood from peripheral vein was collected at 1, 3, 5, 7 days of treatment, and CD62p, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were determined by enzyme linked immunosorbent assay (ELISA), D-dimmer was determined by immunoturbidimetry, acute physiology and chronic health evaluationⅡ (APACHEⅡ) score was recorded, and incidence of multiple organ dysfunction syndrome (MODS) was also evaluated.Results There were no significant differences in values of all parameters, including CD62p, D-dimmer, IL-6, TNF-α, and APACHEⅡ score at 1 day of treatment. The values of all parameters in observation group were gradually decreased. CD62p at 3 days of treatment and D-dimmer, IL-6, TNF-α, and APACHEⅡ score at 5 days of treatment were significantly lower than those at 1 day of treatment. The values in the control group were decreased at first and then increased, as D-dimmer, IL-6 and TNF-α were significantly higher on the 5th day than those at 1 day of treatment. Compared with control group, CD62p, D-dimmer, IL-6, TNF-α and APACHEⅡ score on the 7th day of treatment were significantly lowered in observation group [CD62 (μg/L): 22.64±2.88 vs. 31.52±2.81, D-dimmer (g/L): 1.32±0.46 vs. 4.79±0.82, IL-6 (ng/L): 5.84±1.87 vs. 49.64±3.12, TNF-α (ng/L): 21.04±3.15 vs. 130.58±6.26, APACHEⅡ score: 9.71±2.02 vs. 14.17±2.38, allP< 0.05]. Correlation analysis showed that in observation group, CD62p, D-dimmer, IL-6, and TNF-α were positively correlated with APACHEⅡ score (r value was 0.907, 0.868, 0.880, 0.693, respectively, all P=0.000). The incidence of MODS in observation group was significantly lower than that in the control group [26.7% (8/30) vs. 46.7% (14/30),χ2=3.943,P= 0.028].Conclusions LMWH, which was given early in sepsis, can significantly down-regulate the expression of CD62p, D-dimmer, IL-6 and TNF-α, and reduce the incidence of MODS. Some indicators regarding coagulation and inflammation can be used as supplementary indicators to severity scores, and it may be able to improve the accuracy of scoring systems for sepsis.

ABSTRACT

Objective To observe the clinical effects of phosphocreatine treatment on left ventricular function and on amino-terminal pro-brain natriuretic peptide (NT-proBNP) level in elderly patients with chronic heart failure. Methods In our department, the 172 elderly patients with chronic heart failure were randomly divided into treatment group and control group (n= 86, each).The control group received routine anti-heart failure treatment. The treatment group received conventional therapy plus creatine phosphate sodium for 4 weeks. The cardiac function was evaluated and the NT-proBNP level was measured in all subjects. Results Four weeks after treatment, the improvements of left ventricular ejection fraction (LVEF), left ventricular end-systolic diameter (LVESD) and left ventricular end-diastolic dimension (LVEDD) were better in treatment group than in control group (all P<0.05). The plasma NT-proBNP level decreased significantly in treatment group as compared with control group [before treatment: (956.4 ± 644.2) pmol/L and (973.6 ±639.8) pmol/L; after treatment: (414. 5 ± 163.8 ) pmol/L and ( 719.3 ± 477. 5 ) pmol/L, all P<0. 05]. Conclusions Phosphocreatine could improve left ventricular function and decrease plasma NT-proBNP level in elderly patients with chronic heart failure.
