Relationship between injury and alcohol use in 531 patients in the emergency room / 中南大学学报(医学版)

Objective:To determine the relationship between injury risk and alcohol drinking. Methods:Totally 531 patients (age≥18 years) who were treated for the ifrst time and came to the emergency room within 6 h atfer the injury were included. hTe American National Institute of Health questionnaire was used to investigate the trauma type, intentional injury, drinking before the injury, drinking volume, and drinking history in the past years and so on. hTe case-crossover method was used to analyze the data and relationship between alcohol drinking and injury.Results:Compared with the non-drinkers, subjects who drank alcohol 6 h before the injury had a higher risk of intentional injury (OR=2.79, 95%CI: 1.61–4.84). Male, drunken, patients with positive alcohol test results were more likely to suffer from intentional injury. Compared with the non-drinkers, victims who drank alcohol 6 h before injury had a higher risk of injury in traffc accidents (OR=2.41, 95%CI: 1.29–4.51). Compared with the non-drinkers, subjects who drank alcohol 6 h before injury had a higher risk of injury (OR=11.86, 95%CI: 5.48–25.65). Subjects who drank more than 6 standard drinks of alcohol 6 h before injury had much higher risks than non-drinkers (OR=24.52, 95%CI: 5.84–102.86). Conclusion:Alcohol drinking before injury is associated with increased the risk of trauma, intentional injury and injury related to traffc accidents.

Objectives To explore the brain white matter integrity among the patients with buprenorphine tables,scopolamine and promethazine solution(BSP) dependence after abstinence.Methods BSP-dependent patients( n=16)and age/eduction-matched healthy control subjects ( n=18) were assessed by diffusion tensor imaging (DTI) after 3 days,1 month and 2 months of abstinence.White matter (WM) integrity was measured with DTI as fractional anisotropy ( FA),an index of intravoxel orientational coherence of white matter fibers.Results Compared with health controls,FA values were significantly lower in frontal,parietal,temporal and corpus callosum in the BSP addicts after 3-day withdrawal (P＜0.001,uncorrected).Increased FA values in left superior frontal cortex,right medial frontal gyms and fight inferior parietal gyrus were found in BSP users after 2 months of abstinence (P ＜0.001,uncorrected).However,no significant difference was found between these BSP addicts after 1-month abstince.Compared with health controls,BSP dependent subjects still exhibited significantly lower FA in the corpus callosum,frontal,parietal and temporal WM after 2-month withdrawal (P ＜ 0.001,uncorrected ).Conclusion The abnormalities showed less recovery in BSP dependent individuals with abstinence in white matter that suggests that rehabilitation time should be further prolonged for BSP addicts and emphasis cognitive-behavioral therapy to assist BSP abusers rebuild social functions.

Effects of terguride on protein and mRNA expressions of dopamine D2 receptor and dynorphin in different brain regions of rats after heroin self administration / 中国药理学与毒理学杂志

OBJECTIVE To study mechanisms of terguride on the treatment of herion dependence. METHODS Adult male SD rats were randomly assigned into 5 groups: normal control group, saline treatment during heroin use period group, terguride treatment during heroin use period group, saline treatment during heroin reinstatement period group, terguride treatment during heroin reinstatement period group, the last 4 groups established heroin intravenous self administration and cue induced reinstatement models, and after interfernce and perfusion to get the following five brain regions [including ventral tegmental area (VTA)]sections. The expression of dopamine D2 receptor protein and mRNA, prodynorphin protein and preprodynorphin mRNA was detected by immunohistochemistry and hybridization in situ. RESULTS The expression of dopamine D2 receptor was downregulated during heroin use period and upregulated during heroin reinstatement period in nucleus accumbens shell (AcbSH) region, the expression of dopamine D2 receptor mRNA was parallelled with the protein expression approximately, terguride could downregulate the high expression of receptor protein during reinstatement. The expression of dopamine D2 receptor protein and mRNA was upregulated during heroin reinstatement period in central nucleus amygdalae (CeA) region, and terguride could downregulate this high expression. The expression of dopamine D2 receptor protein and mRNA was upregulated during heroin use period and downregulated during heroin reinstatement period in CA1 region of hippocampus and prefrontal cortex (PFC), terguride could downregulate the high expression of mRNA during heroin reinstatement period. The expression of dynorphin protein and mRNA was upregulated during heroin reinstatement period, terguride could downregulate this high expression. The expression of dynorphin protein was upregulated during heroin reinstatement period, and terguride could downregulate this high expression. CONCLUSION The activity of mesolimbic dopamine is boosted up during heroin use period and depressed during reinstatement period, terguride can regulate this dysregulation. The activity of dynorphin is boosted up during cue induced reinstatement, and terguride has the downregulation effect. So the preclinic study demonstrated that terguride has the potential benefit in heroin dependence.
