ABSTRACT
Objective:To investigate the therapeutic effect of the combination of mouse nerve growth factor and edaravone in the treatment of carbon monoxide poisoning and its effect on patients′ cognitive function, lactic acid clearance rate, and related indicators of oxygen free radicals.Methods:A selection of 158 patients with carbon monoxide poisoning in the Huxi Hospital Affilliated Jining Medical College from May 2017 to June 2020 were divided into study group (80 cases) and control group (78 cases) according to the treatment plan. Both groups were given conventional treatment. On this basis, the control group was given edaravone, and the study group was given mouse nerve growth factor combined with edaravone, both of which were treated for 2 weeks. The clinical efficacy of the two groups was compared with those before treatment and 1 week and 2 weeks after treatment. Neurological impairment score (NIHSS), disease severity score (APACHE Ⅱ), cognitive function score (MMSE), serum inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), C-reactive protein (CRP)], oxygen free radical related indicators [lipid peroxide (LPO), superoxide dismutase (SOD), gluten Glutathione peroxidase (GSH-PX), malondialdehyde (MDA)] levels, blood lactic acid levels before treatment and lactic acid clearance rates after 12 h, 24 h, 72 h treatment, and statistics of adverse reactions and 30-day mortality.Results:The total effective rate of the study group was higher than that of the control group after 2 weeks of treatment [95.00% (76/80) vs. 78.21% (61/78)] ( P<0.05); NIHSS and APACHEⅡ scores of the study group after 1 week and 2 weeks of treatment Lower than the control group: (6.08 ± 1.15) points vs. (8.94 ± 1.71) points, (4.58 ± 0.74) points vs. (6.32 ± 0.93) points and (6.79 ± 1.03) points vs. (8.02 ± 1.47) points, (5.94 ± 1.47) points vs. (7.25 ± 0.94) points, the MMSE score was higher than that of the control group: (22.09 ± 4.35) points vs. (19.34 ± 5.32) points, (26.05 ± 2.37) points vs. (22.47 ± 4.64) points ( P<0.05) After 1 and 2 weeks of treatment, the serum TNF-α, IL-6, CRP, LPO and MDA levels in the study group were lower than those in the control group: (22.62 ± 4.12) ng/L vs. (29.43 ± 4.68) ng/L and (18.21 ± 2.09) ng/L vs. (24.37 ± 3.16) ng/L, (39.67 ± 4.35) ng/L vs. (52.14 ± 5.48) ng/L and (34.83 ± 3.75) ng/L vs. (41.07 ± 4.09) ng/L, (12.63 ± 1.85) mg/L vs. (17.02 ± 2.47) mg/L and (8.27 ± 1.16) mg/L vs. (11.05 ± 1.62) mg/L, (11.06 ± 1.28) μmol/L vs. (15.97 ± 1.85) μmol/L and (8.24 ± 1.12) μmol/L vs. (12.97 ± 1.40) μmol/L, (7.15 ± 1.16) μmol/L vs. (9.02 ± 1.47) μmol/L and (6.12 ± 0.96) μmol/L vs. (7.84 ± 1.25) μmol/L, the levels of SOD and GSH-PX were higher than those in the control group ( P<0.05); the lactate clearance rate in the study group was higher than that in the control group after 12, 24 and 72 h of treatment: (18.49 ± 3.63)% vs. (14.62 ± 2.95)%, (23.19 ± 4.20)% vs. (17.42 ± 3.57)%, (29.86 ± 6.37)% vs. (25.38 ± 5.21)% ( P<0.05); the incidence of adverse reactions in the study group during treatment Compared with the control group, there was no significant difference ( P>0.05); there was no significant difference in the 30-day mortality between the study group and the control group ( P>0.05). Conclusions:The combination of mouse nerve growth factor and edaravone in the treatment of carbon monoxide poisoning can reduce the severity of disease and neurological deficits, improve cognitive function and lactate clearance rate, reduce inflammation and oxidative stress, improve efficacy, and have good safety.
ABSTRACT
ObjectiveTo investigate the changes of serum creatine kinase isoenzyme (CK-MB) and creatine kinase (CK) ratio(CK-MB/CK) and cardiac troponin I(cTnI) simultaneously in patients with acute organophosphorus pesticide poisoning (AOPP) and the clinical value in disease condition judgment.Methods Eight hundred and sixty-eight AOPP patients without disease history of heart,lung,brain,kidney,muscle and other connective tissue were extracted 4 ml of fasting venous blood to determine CK,CK-MB and cTnI simultaneously at 2,12,24,48,96 and 120 hours after poisoning,and the CK-MB/CK was calculated.There were 279 mild poisoning cases (mild poisoning group),289 moderate poisoning cases (moderate poisoning group) and 300 severe poisoning group (severe poisoning group) ; and 208 cases with intermediate myasthenia syndrome (IMS)(IMS group) and 660 cases without IMS (non-IMS group).The result was compared with 288 healthy people (control group) in the same period.Results ( 1 ) The CK,CK-MB and cTnI of mild,moderate and severe poisoning groups between 2 to 12 h,13 to 24 h,25 to 120 h after poisoning were significandy higher than those in control group,CK-MB/CK was obviously lower (P ＜ 0.01 ).The CK,CK-MB,cTnI and CK-MB/CK had significant differences between each two of mild,moderate and severe poisoning groups (P＜ 0.01 or ＜ 0.05).The CK,CK-MB and cTnI of IMS group in 2 to120 h after poisoning were significantly higher than those in non-IMS group,and CK-MB/CK was lower (P ＜ 0.05 or ＜ 0.01 ).In IMS group,the rates of sudden cardiac death (SCD) and multiple organ dysfunction syndrome (MODS) were 23.08％(48/208),37.50％(78/208) respectively,while 4.24％(28/660),9.85％(65/660) in non-IMS group.The incidence of SCD and MODS of two groups had statistical significance (P ＜ 0.01 ).(2) According to IMS and non-IMS group,discriminant equation with independent variables of cTnI (X1), CK (X2) and CK-MB/CK (X3) was established:Y =-0.0014X1 + 0.0225X2 + 65.2376X3,F=21.4911,P ＜ 0.01.The discriminant critical value(Y0) was 2.8124.If Y ＜ 2.8124 belonged to IMS group and Y ≥2.8124 was in non-IMS group,the contribution rates of X1,X2 and X3 were 34.5％,25.4％ and 40.1％ respectively.The coincident rate of return was 91.26％.ConclusionsCK-MB/CK change has negative correlation with poisoning degree of AOPP;cTnI level is positively correlated with AOPP poisoning degree.they may be used to assist the clinical classification,disease judgement and to guide the emergency,treatment and prognosis assessment of AOPP.The function equation with cTnI,CK and CK-MB/CK can be used as effective prediction indexes of IMS,MODS and SCD in early period.
ABSTRACT
Objective To investigate the effects of application and clinical value of the epinephrine with graduate increased dosage by the modality equation G=(K+2n-1)mg/3 min(K=1,2,n=1,2,3……,G≤0.2 mg/kg)and aminophylline and sheng-mai injection with uniform method at the same time rapidly combination on cardiopulmonary resuscitation (CPR).MethodsThree hundred and twenty-eight cases with sudden cardiac-arrest (CA) were randomly divided into 3 groups：112 cases with the standard-dose epinephrine group (SDE control group);106 cases with the first-dosage epinephrine for K=1 mg in the equation G=(K+2n-1)mg/3min (K=1,2,n=1,2,3……,G≤0.2 mg/kg,group (equation 1 group) and 110 cases with the first-dosage epinephrine for K=2mg(epuation 2 group).Patients'electrocardiogram and mean arterial pressure(MAP)and the heart rate(HR)and the time of recovery of spontaneous circulation (ROSC)were monitored,and the resuscitation effect were evaluated.ResultsTo compare the equation 2 group and equation 1 group with the SDE control group,the ROSC rate,the survival rate,the 24-hour survival rate and the scoring by Glasgow coma scale were all significantly elevated(P＜0.01)：but the average time from initial stage applied with the epinephrine in the CPR to ROSC in the equation 2 group and equation 1 group was much shorten significantly than that in the SDE control group(P＜0.01).To compare the equation 2 group and equation 1 group with the SDE control group：the average dose of the epinephrine was much reduced from initial stage applied with the epinephrine on CPR to ROSC(P＜0.05),but the cycle summation of apphcation epinephrine by mainline from the CPR initial stage to ROSC in the equation 2 group and equation 1 group was much significantly decreased than that in the SDE control group(P＜0.01).ConclusionsThe method of the epinephrine with graduate increased dosage by the equation G=(K+2n-1) mg/3min(K=1,2,n=1,2,3……,C≤0.2mg/kg)and aminophylline and sheng-mai injection with uniform method at the same time rapidly combination on CPR has better effects on increasing significandy the success rate of CPR,the survival rate,the time activity of success and shortening significantly time of the ROSC,improving brain and nervous system function.It can be new and effective method to increasing the success rate of resuscitation on the CPR.
