ABSTRACT
The method of scoping review was used to systematically search and sort out the clinical research of oral Chinese patent medicines for ischemic stroke，to understand the scope of relevant research and the distribution of evidence. Three medical catalogs were manually searched to obtain the oral Chinese patent medicines used for ischemic stroke，and 7 databases were retrieved to obtain the clinical research including these oral Chinese patent medicines. Then the clinical evidence results were visualized by description combined with chart analysis. A total of 68 oral Chinese patent medicines were retrieved，and 1 392 articles were included，with 367 published in core journals， involving 35 oral Chinese patent medicines. The research types included randomized controlled trials，cohort studies，case series，case reports，secondary studies，adverse drug reaction reports，pharmacoeconomic evaluations，drug interactions，consensus or guidelines，non-randomized intervention studies and cross-sectional studies，of which randomized controlled trials had the largest number （283， 77.1%），followed by secondary studies and case series （25， 6.7% for each）. Among the 283 randomized controlled trials，there were 159 clinical studies in the acute phase of ischemic stroke，65 in the non-acute phase，and 59 in the unclear phase. Ten intervention control types and 20 outcome index types were summarized. Among them， the composite outcome index and surrogate outcome index were used 217 times （76.7%） and 245 times （86.6%）， respectively，followed by the degree of neurological impairment （three scales）. Future clinical research of oral Chinese patent medicines for ischemic stroke should clarify the stage of the disease，and the research design should specify the advantages of oral Chinese patent medicines intervening in ischemic stroke. Furthermore， publicly-recognized positive controls should be employed，and important clinical outcome indexes should be selected.
ABSTRACT
Objective:To investigate the value of quantitative electroencephalography (qEEG) in the evaluation of thrombolytic efficacy in acute cerebral infarction.Methods:A prospective cohort study was conducted. Ninety-four patients with acute cerebral infarction who received intravenous thrombolysis admitted to the department of emergency of Qinhuangdao First Hospital from October 2019 to September 2020 were enrolled. The relative energy values of δ, θ, α and β waves in qEEG before and 2 hours, 24 hours and 7 days after intravenous recombinant tissue plasminogen activator (rt-PA) thrombolysis were dynamically monitored, and the power ratio index [DTABR, DTABR = (δ+θ)/(α+β)] was calculated. The National Institutes of Health stroke scale (NIHSS) score was also recorded. The reduction of NIHSS score ≥ 3 or the disappearance of neurological symptoms were regarded as effective thrombolytic therapy. The changes of DTABR before and after thrombolysis in patients with effective and ineffective thrombolysis were analyzed, and the correlation between DTABR and NIHSS score was analyzed by Pearson method.Results:A total of 94 patients were enrolled, including 64 males and 30 females. The average age was (61.71±10.11) years from 36 to 89 years old. Thrombolysis was effective in 57 cases and ineffective in 37 cases. Compared with before thrombolysis, DTABR of the effective group was significantly decreased at 2 hours, 24 hours and 7 days after thrombolysis (left cerebral infarction: 1.87±1.45, 1.59±0.88, 1.58±0.90 vs. 3.82±2.60; right cerebral infarction: 1.55±0.57, 1.41±0.50, 1.35±0.44 vs. 3.20±1.63, all P < 0.05). DTABR did not change or increase significantly at 2 hours, 24 hours and 7 days after thrombolysis compared with before thrombolysis (left cerebral infarction: 3.56±2.57, 3.48±2.19, 3.54±2.50 vs. 3.11±1.62; right cerebral infarction: 5.29±3.93, 5.33±3.94, 5.19±4.52 vs. 4.73±2.43, all P > 0.05). Pearson correlation analysis showed a significant positive correlation between DTABR and NIHSS score in patients with acute cerebral infarction (r = 0.691, P < 0.01).Conclusion:The quantitative index of qEEG, DTABR, can accurately and quickly monitor the process of thrombolysis in acute cerebral infarction, and can effectively evaluate the effect of thrombolysis in patients.
ABSTRACT
Objective:To analyze the distribution and composition characteristics of jellyfish stings in various coastal baths in Qinhuangdao City from 2017 to 2019, and to provide scientific basis for the prevention, control and early warning of jellyfish stings.Methods:Statistics and analysis of the age, gender, time of stings, location of injury, first symptoms, and playing time in the sea at the time of the sting, etc. of people with jellyfish stings in various bathing beaches along the coast of Qinhuangdao from 2017 to 2019 (July to August) were conducted.Results:The number of jellyfish stings in the coastal bathing beaches of Qinhuangdao City in 2017, 2018, and 2019 was decreasing year by year, with 1 890, 492, and 171 cases respectively. Among them, Qianshuiwan Bathing Beach and Dongshan Bathing Beach had more stings (60.90% and 35.08% respectively in 2017, 24.39% and 64.23% respectively in 2018, 16.96% and 16.42% respectively in 2019). There was no significant change in the gender and age distribution of jellyfish stings each year [57.99% males in 2017, with a median age of 13 (8, 31) years old; 63.21% males in 2018, with a median age of 25 (8, 29) years old; and 59.65% males in 2019, with a median age of 12 (7, 31) years old]. Stings were mainly located at the lower limbs (the proportion of lower limb injuries: 46.54% in 2018, 45.61% in 2019), followed by upper limbs (upper arm, elbow, forearm), trunk, etc. The first symptom was mainly pain (89.43% in 2018, 38.29% in 2019), followed by rash (64.43% in 2018, 59.43% in 2019), numbness, blisters, etc. Sting incidents mainly occurred from 13:00 to 17:59 (the proportion of sting incidents in this time period in 2018 and 2019 were 68.09% and 52.63%, respectively).Conclusions:Jellyfish stings in coastal baths in Qinhuangdao City are mainly distributed in Qianshuiwan Baths and Dongshan Baths. The management of these sea areas should be strengthened, and scientific publicity and medical rescue should be strengthened to prevent jellyfish stings in peak hours and related baths.
ABSTRACT
Synergistic effects of drug combinations are very important in improving drug efficacy or reducing drug toxicity. However, due to the complex mechanism of action between drugs, it is expensive to screen new drug combinations through trials. It is well known that virtual screening of computational models can effectively reduce the test cost. Recently, foreign scholars successfully predicted the synergistic value of new drug combinations on cancer cell lines by using deep learning model DeepSynergy. However, DeepSynergy is a two-stage method and uses only one kind of feature as input. In this study, we proposed a new end-to-end deep learning model, MulinputSynergy which predicted the synergistic value of drug combinations by integrating gene expression, gene mutation, gene copy number characteristics of cancer cells and anticancer drug chemistry characteristics. In order to solve the problem of high dimension of features, we used convolutional neural network to reduce the dimension of gene features. Experimental results showed that the proposed model was superior to DeepSynergy deep learning model, with the mean square error decreasing from 197 to 176, the mean absolute error decreasing from 9.48 to 8.77, and the decision coefficient increasing from 0.53 to 0.58. This model could learn the potential relationship between anticancer drugs and cell lines from a variety of characteristics and locate the effective drug combinations quickly and accurately.

Objective:To analyze the status quo of bystander cardiopulmonary resuscitation (BCPR) for out-of-hospital cardiac arrest (OHCA) in Qinhuangdao area and its influence on the prognosis of cardiopulmonary resuscitation (CPR).Methods:Based on the Utstein model CPR database of Qinhuangdao, data of 1 162 OHCA patients admitted to the Health Emergency Dispatch Center of Qinhuangdao City from January 2018 to January 2019 were collected, and they were divided into two groups according to whether BCPR was performed or not. The patients' demographic parameters (gender, age), precardiac arrest parameters (location of cardiac arrest), the parameters of the CPR (first aid response time before hospital, initial diagnosis of causes of cardiac arrest, initial cardiac rhythm) and the parameters of the CPR results [whether to achieve on-site restoration of spontaneous circulation (ROSC) and 30-day survival rate] were collected. Multivariate Logistic regression analysis was performed for the relationship between BCPR and on-site ROSC rate. The social characteristics of bystanders implementing BCPR, including gender, age, occupation, educational background, and acquisition method of CPR knowledge, were analyzed.Results:Among the 1 162 OHCA patients, the patients witnessed by professional medical personnel in nursing homes, hospitals and other places and pre-hospital emergency personnel were excluded. 852 OHCA patients were enrolled, among which only 24 patients obtained BCPR (2.8%), and the remaining 828 patients did not obtain BCPR (97.2%). There were no statistically significant differences in gender, age, location of cardiac arrest, pre-hospital emergency response time, primary diagnosis of cardiac arrest causes and initial cardiac rhythm between the two groups. Compared with the non-BCPR group, the on-site ROSC rate and the 30-day survival rate of the BCPR group were significantly increased [on-site ROSC rate: 16.7% (4/24) vs. 5.2% (43/828), 30-day survival rate: 8.3% (2/24) vs. 1.3% (11/828), both P < 0.05]. Multivariate Logistic regression analysis showed that BCPR [odds ratio ( OR) = 32.132, 95% confidence interval (95% CI) was 11.129-65.471], location of cardiac arrest ( OR = 0.080, 95% CI was 1.212-3.125) and response time during pre-hospital emergency treatment ( OR = 0.121, 95% CI was 0.174-0.816) were important factors for on-site ROSC of OHCA patients (all P < 0.01). A total of 30 bystanders participated in the implementation of OHCA patients' BCPR, excluding 2 bystanders of lost follow-up, 28 bystanders with effective return visit. The 28 bystanders of BCPR practitioners were mainly male (85.7%), the age was mainly 18-40 years old (57.1%), the occupation was mainly in the tourism service industry (21.5%), students (17.9%), soldiers (14.3%) and bus drivers (10.7%), and the education background was mainly junior college or above (85.7%), the methods of acquiring CPR knowledge mainly included APP and new media (42.9%) and lectures (21.4%). Conclusions:The BCPR implementation rate of OHCA in Qinhuangdao was only 2.8%. BCPR can improve the success rate of pre-hospital CPR and the 30-day survival rate of OHCA patients. Targeted selection of tourism service industry, students, military personnel and bus drivers as CPR training targets may obtain more significant social benefits.
ABSTRACT
To study the effect of mild hypothermiaon neurological function and oxidative stress in patients with acute massive cerebral infarction. Methods Sixty patients with acute massive cerebral infarction (within 12 hours of onset, the age < 70 years old) admitted to the First Hospital of Qinhuangdao from August 2017 to August 2018 were enrolled. Patients were divided into control group and observation group according to random number table method, with 30 patients in each group. The control group was given conventional treatment such as lowering intracranial pressure, anticoagulation, improving microcirculation, neurotrophy and anti-stress ulcer, while the observation group was received mild hypothermia (after 72 hours of treatment at 32-35 ℃, it increased about 1 ℃ every 6 hours until the normal temperature). The neurological impairment (the National Institutes of Health Stroke Scale, NIHSS), motor function (Fugl-Meyer score), daily living ability (Bathel index) and coma degree (Glasgow coma scale, GCS) were observed before treatment and 72 hours after treatment. The levels of plasma malondialdehyde (MDA), superoxide dismutase (SOD) and advanced oxidative protein products (AOPP) were measured at same time. After 72 hours of treatment, the therapeutic effect was judged according to the NIHSS score. Results There was no significant difference in NIHSS score, Fugl-Meyer score, Bathel index and GCS scores, and the levels of plasma MDA, SOD and AOPP between two groups before treatment. Compared with before treatment, NIHSS score and plasma MDA and AOPP levels in the two groups were significantly decreased after treatment, while Fugl-Meyer score, Bathel index, GCS score and plasma SOD activity were significantly increased; and the change of observation group was more significant than those of control group [NIHSS score: 9.78±3.24 vs. 13.44±2.63, MDA (mmol/L): 8.70±2.79 vs. 10.50±3.81, AOPP (μmol/L):51.10±17.81 vs. 72.60±18.71, Fugl-Meyer score: 55.68±8.38 vs. 46.25±3.92, Bathel index: 66.63±11.25 vs. 56.71±10.81, GCS score: 13.78±1.31 vs. 10.49±1.03, SOD (kU/L): 134.70±29.87 vs. 104.60±25.75, all P < 0.05]. The total effective rate of the observation group was significantly higher than that of the control group [93.3% (28/30) vs. 86.7% (26/30), χ2 = 6.119, P = 0.020]. Conclusions Mild hypothermia was effective in treating acute massive cerebral infarction. It could significantly improve the neurological function and oxidative stress of patients, improve the quality of life, and was safe and reliable.
ABSTRACT
Objective To investigate the role of p38 mitogen-activated protein kinase (p38MAPK) signaling pathway in the expression of aquaporin 4 (AQP4) in brain tissue of rats with cardiopulmonary resuscitation (CPR) during mild hypothermia. Methods Forty-eight healthy male Sprague-Dawley (SD) rats were divided into sham operation group, normal temperature group and mild hypothermia group according to random number table method, with 16 in each group. The rat model of cardiac arrest-cardiopulmonary resuscitation (CPR) was established by asphyxia method. The sham operation group only experienced venous catheterization and tracheal intubation. The mild hypothermia group was treated with hypothermia 0.5 hours after restore of spontaneous circulation (ROSC, maintaining esophageal temperature at 32-34 ℃); the normal temperature group was treated at room temperature after ROSC (maintaining esophageal temperature at 36-38 ℃). Brain tissue was harvested at 6 hours after ROSC, and histopathological changes were observed by hematoxylin-eosin (HE) staining. The water content of brain tissue was determined by dry-wet specific gravity method. The protein expressions of phosphorylation of p38 mitogen-activated protein kinase (p-p38MAPK), p38MAPK and AQP4 in brain tissue were determined by Western Blot. Results Compared with the sham operation group, the nerve cells in the normal temperature group were reduced in size, cytoplasmic loosening, nuclear pyknosis, and in apoptotic body formation, water content of brain tissue was significantly increased [(83.64±2.53)% vs. (77.95±0.94)%, P < 0.05], the protein expressions of p-p38MAPK, p38MAPK, AQP4 were significantly increased (p38MAPK/β- actin: 1.010±0.217 vs. 0.427±0.090, p-p38MAPK/p38MAPK: 0.451±0.172 vs. 0.191±0.141, AQP4/β- actin: 3.129±0.754 vs. 1.598±0.464, all P < 0.05). Compared with the normal temperature group, the degree of necrosis of nerve cells in the mild hypothermia group was reduced, the water content of brain tissue was significantly decreased [(80.49±2.05)% vs. (83.64±2.53)%, P < 0.05], the protein expression of p38MAPK, p-p38MAPK and AQP4 in brain tissue were significantly decreased (p38MAPK/β- actin: 0.590±0.162 vs. 1.010±0.217, p-p38MAPK/p38MAPK: 0.298±0.076 vs. 0.451±0.172, AQP4/β- actin: 2.061±0.340 vs. 3.129±0.754, all P < 0.05). Conclusion Mild hypothermia may regulate the expression of AQP4 in brain tissue of CPR rats through p38MAPK signaling pathway, and reduce brain edema, thereby exerting brain protection.

ABSTRACT
Conventional oxygen therapy (COT) is generally provided through a low flow rate device including a nasal cannula or facemask. Since the benefits of high-flow nasal cannula (HFNC) oxygen therapy in adults with acute respiratory failure (ARF) have firstly been demonstrated by Roca et al and because of its effectivity and comfort and good compliance, it has shown greater advantageous than COT and it has been increasingly used in adults with mild to moderate ARF and obtained very nice therapeutic effect. However, because of the specificity of emergency environment and the more complexity of HFNC system than COT, the use of HFNC in department of emergency is still controversial. Since HFNC system delivers oxygen by high-flow rate, the dilution of inspired oxygen concentration (FiO2) by room air can be maximally decreased, and the system can provide the highest flow rate up to 60 L/min, being greater than the patients' peak inspiration flow flow (PIF); the high flow rate can dilute the carbon dioxide (CO2) concentration in the anatomical dead space, and the above several factors can guarantee that HFNC may deliver 0.21-1.00 relatively constant FiO2. Therefore, HFNC as a new noninvasive supplemental oxygen therapy has been increasingly widely studied and used in the adult patients with ARF. In this article, we will review the HFNC physiological effects and its advances in application for adult patients in department of emergency.
ABSTRACT
Objective@#To investigate the prehospital intervention based on emergency medical services (EMS) in patients with acute ischemic stroke (AIS) for door-to-needle time (DNT) with intravenous thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA) impact.@*Methods@#112 emergency patients receiving rt-PA intravenous thrombolysis admitted to the First Hospital of Qinhuangdao City based on EMS from June 2016 to December 2017 were enrolled. According to whether or not to receive prehospital interventions, patients were divided into prehospital intervention group (n = 42) and routine treatment group (n = 70). Both groups followed the general principles of first aid, including assessment and support of the airway, respiration, and circulation, and blood glucose, electrocardiogram, and dynamic vital signs were monitored. Based on the general principle of EMS, first-aid personnel in the prehospital intervention group screened suspected acute stroke patients requiring prehospitalization according to Los Angeles prehospital stroke screening table (LAPSS), and established fluid ways, and got blood samples to evaluate rt-PA intravenous thrombolysis and risks. Factors influenced DNT compliance were analyzed through multivariate Logistic regression, which included the education level of the patient, whether there were risk factors related to cerebrovascular disease (hypertension, coronary heart disease, diabetes), visit time, National Institute of Health stroke scale (NIHSS) score, whether received EMS intervention or not. The average DNT, DNT ≤ 60 minutes compliance rate, communication time, and decision time for thrombolysis were compared between the two groups. NIHSS score was used to evaluate the effective rate of thrombolysis for 7 days. The modified Rankin score (mRs) was used to evaluate the neurological function after 3 months of thrombolysis (a mRs score of 0-2 was defined as a good nerve function).@*Results@#Univariate analysis showed that the DNT of patients with NIHSS score > 5 was significantly shorter than those with NIHSS score≤5, and DNT in patients received EMS intervention was significantly shorter than the non-receiver; but education level, visiting time, and risk factors associated with cerebrovascular disease had nothing to do with DNT. Multivariate Logistic regression analysis showed that NIHSS score and EMS intervention were the influencing factors of DNT compliance [NIHSS score: odds ratio (OR) = 0.452, 95% confidence interval (95%CI) = 0.162-1.263, P = 0.030; EMS intervention: OR = 3.077, 95%CI = 1.260-7.514, P = 0.014]. Compared with conventional treatment group, DNT of intravenous thrombolytic in prehospital intervention group was significantly shortened (minutes: 62.00±11.07 vs. 78.03±21.04), DNT≤60 minutes compliance rate was significantly increased [35.7% (15/42) vs. 12.9% (9/70)], communication time [minutes: 4 (3, 6) vs. 6 (5, 9)] and decision-making thrombolytic time (minutes: 5.81±2.48 vs. 6.70±2.15) were significantly shortened, the differences were statistically significant (all P < 0.05). The 7-day effective rate in the prehospital intervention group [33.3% (14/42) vs. 14.3% (10/70), χ2 = 5.657, P = 0.017] and the 3-mouth good rate of nerve function [38.1% (16/42) vs. 14.3% (10/70), χ2 = 10.759, P = 0.001] were significantly higher than those in the conventional treatment group.@*Conclusion@#Prehospital interventions based on EMS can shorten DNT of intravenous thrombolysis in the patients with AIS, improve treatment efficiency, and improve prognosis.
ABSTRACT
Objective To analyze the epidemiological characteristics of patients with sea lice injury in coastal baths in Qinhuangdao City, and provide scientific evidence for the importance of prevention of sea lice injury and the early warning of sea lice outbreak. Methods The data of 2 659 patients with sea lice injury, including gender, age composition, severity of bruises and other epidemiological data reported by the coastal bathing stations in Qinhuangdao City from 2016 to 2018 (mainly from July to August) were retrospectively analyzed, and the correlation between the temperature at the surface of sea water and the number of patients with sea lice injury was also analyzed. Results Among the 7 bathing beaches along the coast of Qinhuangdao City, Dongshan Bathing Spot (1 101 cases) and Repulse Bay Bathing Beach (1 365 cases) had the largest numbers of bruises, while the Gold Coast Bath had the least (only 5 cases), and the differences in number of bruises in different baths were statistically significant in 2016, 2017, 2018 years (277, 1 890, 492 cases respectively, χ2= 490.611, P < 0.05). Among 2 659 patients, 1 124 were children (≤14 years old), 1 535 were adult, 1 570 male and 1 089 female patients. The severity type of patients' sea lice injury in each bath was mainly mild to moderate type; among the total injury cases, there were 2 589 cases with mild type injury accounting for 97.37%, 61 cases with moderate type (2.29%) and 9 cases with severe type (0.34%). A linear trend between sea surface temperature and the patients' number of bruises was seen, and there was a positive correlation between the sea surface temperature and the patients' number (r = 0.433, P < 0.05). Conclusion The sea lice injuries in Qinhuangdao City are mainly distributed in the Dongshan and Repulse Bay Baths, the main type of injury is light one, and in the mean time the injury is influenced by factors such as popularization of science, medical care, environmental factors, and collective sea lice drift, etc.
ABSTRACT
Objective To objectively and standardly compare the bare-handed CPR and Thumper cardiopulmonary resuscitation CPR recovery effect based on cardiopulmonary resuscitation (CPR) Utstein model.Methods A retrospective study was conducted. CPR adult patients admitted to the Emergency Room of First Hospital of Qinhuangdao in Hebei Province from January 2015 to January 2017 were enrolled. Seventy patients who underwent CPR using the Thumper cardiopulmonary resuscitator were included in the Thumper CPR group; 80 patients who underwent manual hand-held CPR were included in the bare-handed CPR group. Return of spontaneous circulation (ROSC) and return of spontaneous breathing, and blood gas analysis indexes of recovery for 5 minutes and 15 minutes [arterial oxygen partial pressure (PaO2), arterial blood carbon dioxide partial pressure (PaCO2), arterial blood oxygen saturation (SaO2), blood lactic acid (Lac)] were collected.Results There was no significant difference in gender, age and cardiac arrest (CA) causes between the two groups. Compared with the bare-handed CPR group, the ROSC rate in the Thumper CPR group was significantly increased [68.57％ (48/70) vs. 51.25％ (41/80),χ2 = 4.642,P = 0.031], but there was no significant difference in return of spontaneous breathing rate [48.57％ (34/70) vs. 47.50％ (38/80),χ2 = 0.017,P = 0.896]. There was no significant difference in blood gas index between the two groups after 5 minutes of recovery. The PaO2 and SaO2 in the Thumper CPR group were significantly higher than those in the bare-handed CPR group [PaO2 (mmHg, 1 mmHg = 0.133 kPa): 88.13±5.06 vs. 84.26±5.53, SaO2: 0.828±0.068 vs. 0.766±0.031, bothP < 0.05), PaCO2 and Lac were significantly lower than those in the bare-handed CPR group [PaCO2 (mmHg):34.04±4.62 vs. 40.43±5.29, Lac (mmol/L): 6.90±2.07 vs. 8.50±2.12, bothP < 0.05].Conclusions In the process of emergency rescue, Thumper cardiopulmonary resuscitator is more successful than bare-handed CPR. The recovery rate of Thumper cardiopulmonary resuscitator is more conducive to save manpower and obtain better metabolic effect, which is worthy of clinical promotion and application.

Objective To investigate the potential factors which have impact on the working space for surgeons in gasless laparoscopic cholecystectomy and to probe into the specifications of gasless surgeries.Methods Clinical data of 49 cases of gasless laparoscopic cholecystectomy between March 2007 and July 2010 were summarized.The impacts of body mass index,bowel preparation and means of anesthesia on operation time and conversion to laparotomy were analyzed.Results For patients with body mass index ≤25and ＞ 25,operation times were (43.0 ± 5.4) min,and (52.8 ± 7.4 ) min,respectively,and rates of conversion to laparotomy were 0/34 and 4/15,respectively.Both indices in the first group were higher.For patients with and without bowel preparation,operation times were (44.5 ± 5.4) min and (46.1 ± 8.0)min,respectively,and rates of conversion to laparotomy were 2/26 and 2/23,respectively.For patients with epidural anesthesia and lumbar/epidural anesthesia,operation times were (46.5 ± 7.9) min and (44.1 ±6.8) min,respectively,and rates of conversion to laparotomy were 2/24 and 2/25,respectively.Conclusions The operation time of gasless laparoscopic cholecystectomy could be affected by many factors,such as body mass index.Gasless operations can be improved by evaluating the conditions of patients correctly and by selecting suitable operation methods,anesthesia means and bowel preparation.
ABSTRACT
Objective To study the therapeutic effect and significance of Naloxane on the brain function in patients with acute organ phosphorus pesticide poisoning. Methods 106 patients with acute organ phosphorus pesti-cide poisoning were randomly allocated to two groups according to the hospitalized date, the NX group(n=54) and the normal group(n=52). The two groups received the same basic treatment and the dynamic monitor about the changes of the β-EP and MDA levels in each groups, and the NX group was given additional treatment with 0.8 mg Naloxone-intravenous injection every 20 minutes till consciousness recovering or symptoms improved. Results The time of recovering consciousness was (16.71±3.17)h in NX group and (20.84±3.25)h in control group. β-EP and MDA were higher than normal before treatment in all patients (P<0.01), and were significantly reduced after treatment in NX group (P<0.05), the control group had mild change after treatment. Conclusion Relating to the inhibition of oxygen free radicals, Naloxone can reduce time of recovering consciousness and can protect the injured brain of the patients with acute organ phosphorus pesticide poisoning.
