ABSTRACT
Objective@#To analyze the using of pre-hospital emergency resources and treatment characteristics of acute alcoholism patients in Guangzhou.@*Methods@#The pre-hospital emergency data of the emergency department of the Second Affiliated Hospital of Guangzhou Medical University from January 1st in 2009 to December 31st in 2018 were obtained from the database of the Guangzhou Emergency Medical Command Center. The related data of patients with acute alcoholism were collected, including gender, age, poisoning severity, treatment results, caller type, number of empty vehicles (empty vehicle was defined as the empty vehicle return caused by the ambulance who did not receive or refused to come to the hospital after the ambulance leaved), departure time (from the ambulance to the completion time), on-site time (from the ambulance to the patient boarding time) and the distribution of pre-hospital emergency time in 24 hours on weekdays and weekends. The relationship between acute alcoholism patients and the peak of in-hospital emergency treatment was analyzed.@*Results@#A total of 2 408 acute alcoholism patients were recorded, among whom 2 109 patients (87.58%) with acute alcoholism, 126 (5.23%) with drug poisoning, 67 (2.78%) with chemical poisoning, 3 (0.13%) with pesticide poisoning, and 103 (4.28%) with other poisoning. Acute alcoholism patients were mainly male, with a total of 1 862 cases (88.29%), and the ratio between males and females was 7.54∶1. In 2 109 patients with acute alcoholism, 93.41% were in the age range of 18-59 years old. The number of mild patients was 1 717 (81.41%), 1 178 (55.86%) needed further treatment, and no patient died. For the occupation of pre-hospital emergency resources, 43.24% (912/2 109) of acute alcoholism called 120 through 110 with empty vehicles of 36.79% (776/2 109), which were significantly higher than the acute cerebrovascular disease [3.83% (362/9 461), 5.80% (549/9 461), both P < 0.01], acute trauma [24.29% (1 708/7 033), 7.96% (560/7 033), both P < 0.01], acute circulation system disease [2.44% (90/3 694), 2.87% (106/3 694), both P < 0.01], and acute respiratory system disease [0.86% (31/3 606), 1.58% (57/3 606), both P < 0.01]. Furthermore, empty vehicles were more likely to happen through 110 with empty vehicles rate of 51.75% (472/912), which was significantly higher than that through the witness [40.82% (60/147), P < 0.01] and relatives and friends [23.24% (244/1 050), P < 0.01]. The driving time and on-site time of acute alcoholism were significantly shorter than those of acute cerebrovascular disease, acute circulation system disease, and acute respiratory system disease [driving time (minutes): 26 (20, 34) vs. 34 (26, 45), 38 (29, 49), 38 (29, 50); on-site time (minutes): 6 (4, 10) vs. 10 (7, 14), 10 (7, 15), 10 (8, 15), all P < 0.01], but there was no statistical difference as compared with acute trauma [driving time (minutes): 26 (20, 34) vs. 29 (20, 42), on-site time (minutes): 6 (4, 10) vs. 7 (4, 11), both P > 0.05].

ABSTRACT
OBJECTIVE:To study the preventive effects of arhinhor-11 on acute alcoholism in mice. METHODS:48 mice were randomly divided into model group (sodium carboxymethyl cellulose),arhinhor-11 low-dose,medium-dose and high-dose groups [1.23,2.46,4.92 g(crude drug)/kg],with 12 mice in each group. Each group was given relevant medicine intragastrically, and 30 min later given 56% liquor intragastrically to induce acute alcoholism model. The disappearance time and recovery time of righting reflex were determined. 160 mice were grouped,given medicine and modeled with the same method,with 40 mice in each group. The alcohol concentration and alcohol dehydrogenase(ADH)activity in liver of 10 mice were determined 0.5,1,2,3 h af-ter giving alcohol. Other 10 mice were included in normal control (ig administration of sodium carboxymethyl cellulose). RE-SULTS:Compared with model group,the disappearance time of righting reflex were prolonged while recovery time shortened in arhinhor-11 groups,and alcohol concentration and ADH activity increased 0.5,1,2,3 h after giving alcohol (P0.05). CONCLUSIONS:Arhinhor-11 has preventive effect on acute alcoholism in mice. It has a positive control effects on the alco-hol concentration in blood and ADH activity in liver.

ABSTRACT
Objective To study the clinical efficacy of naloxone combined with edaravone on acute alcoholism. Methods One hundred and twenty-five patients with acute alcoholism were randomly divided into the control and treatment groups. The control group accepted conventional treatment and taking naloxone, while the treatment group accepted edaravone on the basis. Before and after treatment,the treatment recovery time,recovery respiratory rate time and symptom disappearance time were recorded. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), neuron-specific enolase (NSE), S-100βand vascular cell adhesion points-1 (VCAM-1) were detected. Results After treatment,the recovery time and recovery respiratory rate time of the treatment group were significantly shorter than those of the control group ( <0.05) . In the control group, S-100β was significantly improved after treatment ( <0.05) . NSE, S-100β, VCAM-1 and MDA have significantly decreased ( <0.05) after treatment in the treatment group. Compared with the control group, there were significant differences of S-100β,VCAM-1 and MDA in the treatment group before and after treatment (<0.05) . While SOD and GSH have significantly increased ( <0.05) after treatment and showed significant differences compared with the control group ( <0.05) . Conclusion Naloxone and edaravone combination therapy can improve oxidative stress and nerve damage, which help early rehabilitation in patients with acute alcoholism.
ABSTRACT
Objective This study was designed to determine the influence of acute ethanol intoxication (AEI) on brain edema and aquaporin-4(AQP-4) levels after traumatic brain injury(TBI) in rots. The underlying mechanism was also investigated. Method Severe traumatic brain injury models were made using the Feeny method; acute ethanol intoxication models were established by gavagy. One hundred and ninety-two male SD rats were randomly divided(random number) into four groups, namely the sham operation group(A ), the acute ethanol intoxication group( B ), the traumatic brain injury group(C) and the combination of acute ethanol intoxication with traumatic brain injury group(D). Each group was further divided into four sub-groups according to the time interval between injury and death of the rats. After brain tissue was fixed by affusing paraformaldehyde, the expression of AQP-4 was detected by immunohistochemistry. Water content was detected by dry-wet analysis, and AQP-4 mRNA and protein were detected by RT-PCR and western blotting respectively after the brain tissue was got by rapid decapitation. Data were analyzed by one-way ANOVA. Results The water content of brain tissue and expression level of AQP-4 were not significantly different between groups A and B( P > 0.05); however both were significantly increased in groups C and D relative to group A( P < 0.05). The water content of brain tissue in group D increased by mere than that in group C( P < 0.05), while the expression level of AQP-4 in group D was lower than that in group C(P<0.05). Conclusions Acute ethanol intoxication inhibited the expression of AQP-4,which induced a more severe cerebral edema after traumatic brain injury.
