Many compulsory isolated detoxification centers had already implemented the measure, but rarely a systematically comprehensive research was published. Therefore, the purpose of this paper was to evaluate the effect of “5433” training program as an exercise intervention on addicts during drug treatment and rehabilitation, in order to provide the experimental data for the research about the effects of mental quality and physical quality of addicts. Methods: The 2132 male addicts were randomly divided into experimental group (n = 1020) and control group (n = 1112), experimental group was training by “5433” program, and control group ordinary was managed alone. Before and after one year training, in accordance with the “SCL-90” and “Standards of People’s Republic of China national physique”, the SCL-90 scores, height/weight, vital capacity, step index, grip strength, vertical jump, push-ups, sit-and-reach, one-leg standing with eye-closed, choice reaction index of two groups were detected. Results: 1) The scores of depression, anxiety, paranoia and psychosis in two groups before the experiment are both lower than those after the experiment, and the experimental group decreased more (P 0.05). Conclusion:These initial findings show that The “5433” Training Program was effective more than a simple kinesiotherapy, thereby opening avenues for the rehabilitation of Chinese drug addicts.展开更多

Nonetheless,few studies have examined behavioral adjustment and its plasticity following error commission in methamphetamine（METH） dependence, which is detrimental to human health. Thus, we investigated the behavioral adjustment performance following error commission in long-term METH addicts and how it varied with the application of repetitive transcranial magnetic stimulation（r TMS） of the left dorsolateral prefrontal cortex（DLPFC）. Twenty-nine male long-term METH addicts（for [ 3 years） were randomly assigned to high-frequency（10 Hz, n = 15） or sham（n = 14） r TMS of the left DLPFC during a two-choice oddball task. Twenty-six age-matched, healthy male adults participated in the two-choice oddball task pretest to establish normal performance for comparison. The results showed that 10 Hz r TMS over the left DLPFC significantly decreased the post-error slowing effect in response times of METH addicts. In addition, the 10 Hz r TMS intervention remarkably reduced the reaction times during post-error trials but not post-correct trials. While the 10 Hz r TMS group showed a more pronounced post-error slowing effect than the healthy participants during the pretest, the posterror slowing effect in the posttest of this sample was similar to that in the healthy participants. These results suggest that high-frequency r TMS over the left DLPFC is a useful protocol for the improvement of behavioral adjustment after error commission in long-term METH addicts.展开更多

In the cluster-randomized placebo-controlled trial, 83 detoxified heroin addicts were recruited from a detoxification treatment center in Wuhan, China. Patients in the intervention group （n=41） were given the combined treatment with tyrosine, lecithin, L-glutamine and 5-HTP and those in the control group （n=42） were administered the placebo. The sleep status and the withdrawal symptoms were observed daily throughout the study, and the mood states were monitored pre- and post-intervention. The results showed that the insomnia and withdrawal scores were significantly improved over time in participants in the intervention group as compared with those in the control group. A greater reduction in tension-anxiety, depression-dejection, anger-hostility, fatigue-inertia and total mood disturbance, and a greater increase in their vigor-activity symptoms were found at day 6 in the intervention group than in the control group （all P〈0.05）. It was concluded that the neurotransmitter-precursor-supplement intervention is effective in alleviating the withdrawal and mood symptoms and it may become a supplementary method for patients＇ recovery from heroin addiction.展开更多

Results were shown that there were no significant differences between addiction pictures and non-addiction pictures in clarity, while there were significant differences in pleasure and arousal, as the scores of non-addiction pictures were higher. Correlation analysis indicated that there was obvious positive correlation among clarity, pleasure and arousal of addiction pictures & non-addiction pictures. The coefficients of internal consistency reliability and split-half reliability of 22 pictures’ scores exhibited both over 0.90. ISPSCYIA has proved typical and distinctive through valence assessment, which could be preliminarily applied to measure the characteristics of Chinese adolescents’ internet addiction.展开更多

This was a quasi-experimental study with pretest and posttest. The sample of this study included 30 under treatment male addicts whom were selected through applying random sampling method and were placed in two groups, experimental and control. After holding a preliminary session aiming at aiding the experimental group to become familiar with the procedure, 8 sessions of the mindfulness-based therapy were administered. Assessment tools were Craving Beliefs Questionnaire (CBQ) and the Depression Anxiety Stress Scale (DASS-21). After calculating mean and standard deviation, the obtained data were analyzed using covariance. The results indicated that the mindfulness therapy was significantly effective in controlling drug cravings, decreasing stress, anxiety, and depression of under treatment addicts (p < 0.05).展开更多

Opium is a derivative from a plant family called Papaveracea and contains almost 80 types of alkaloids. Drug addiction causes physiological dependency and its withdrawal lead to some disorders. The aim of this study was to determine the effects of opium consumption and its withdrawal on some blood biochemical factors in addicted people. Methods: We enrolled fifty-six opium addicted people according to the especial criteria to this study. Biochemical blood parameter levels such as fasting blood sugar (FBS), urea, Creatinine (Cr), Aspartate transaminase (AST), Alanine transaminase (ALT) and Alkaline phosphatase (ALP) enzymes levels were measured and urine analysis was also performed before and 3 months after withdrawal. Data were analyzed by using SPSS software version 18 and a P < 0.05 was considered as significant. Results: our finding showed that opium withdrawal reduces FBS and increases AST but these changes were not significant. Nevertheless opium withdrawal significantly increased blood urea level (P < 0.0001). We didn’t find any significant difference in Cr, ALP, AST and Urea specific gravity (SG). Conclusion: According to the results of the current study we can concluded that opium increases FBS, which is in contrast to the most previous studies and withdrawal has opposite effects.展开更多

Addictive substances can be categorized as natural, semi-synthetic, or synthetic based on their origin. Additionally, they can be classified into three groups according to their pharmacological targets: opioids, hallucinogens, and cannabinoids that act on G-protein-coupled receptors (GPCRs);alcohols, nicotine, ketamine, barbiturates, and benzodiazepines (BDZs) that affect ligand-gated ion channel-type receptors;and psychostimulants that interact with monoamine transporters. Current treatments for drug addiction primarily include substitution therapy and non-pharmacological approaches. However, these methods have limitations, particularly in addressing the underlying causes of relapse. Several drugs in clinical trials have demonstrated potential therapeutic effects for addiction to opioids, heroin, cocaine, and other substances. This review examines the origins and pharmacological mechanisms of addiction to naturally-derived psychoactive substances (NPS) and provides an overview of recent advancements in pharmacotherapy for drug addiction.展开更多

文摘AIM:To assess the acceptance,safety and efficacy of care and treatment for chronic hepatitis C(CHC)in drug addicts.METHODS:We designed a multidisciplinary,phase IV prospective cohort study.All illicit drug users(IDUs)visited a Territorial Addiction Service(SerT)in the District of Brescia,and hepatitis C antibody(HCVAb)testing positive were offered as part of a standardised hepatologic visit in our Gastroenterology Unit.Patients with confirmed CHC and without medical contraindications were administered peginterferon alfa-2b 1.5μg/kg per week plus ribavirin(800-1400 mg/d)for 16-48wk.All IDUs were unselected because of ongoing addiction and read and signed an informed consent form.Virologic responses at weeks 4 and 12 of therapy,at the end of treatment and 24 wk after the end of treatment were the main measures of efficacy.Adherence was estimated according to the 80/80/80 criteria.RESULTS:From November 2007 to December 2009,162 HCVAb+IDUs were identified.Sixty-seven patients(41%of the initial cohort)completed the diagnostic procedure,and CHC was diagnosed in 54(33%of the total).Forty-nine patients were offered therapy,and 39agreed(80%of acceptance rate).The prevalent HCV genotype was type 1,and the HCV RNA baseline level was over 5.6 log/mL in 61%of cases.Five patients dropped out,two because of severe adverse events(SAEs)and three without medical need.Twenty-three and 14 patients achieved end of treatment responses(ETRs;59%)and sustained virologic responses(SVRs;36%),respectively.Thirty-one patients were fully compliant with the study protocol(80%adherence).The prevalence of host and viral characteristics negatively affecting the treatment response was high:age over40 years(54%),male gender(85%),overweight body type(36%),previous unsuccessful antiviral therapy(21%),HCV genotype and viral load(60%and 62%,respectively),earlier contact with HBV(40%)and steatosis and fibrosis(44%and 17%,respectively).In a univariate analysis,alcohol intake was associated with a non-response(P=0.0018,95%CI:0.0058-0.4565).CONCLUSION:Drug addicts with CHC can be successfully treated in a multidisciplinary setting using standard antiviral combination therapy,despite several"difficult to reach,manage and treat"characteristics.
文摘To develop the initial sandplay picture system for Chinese young internet addicts (ISPSCYIA) for the diagnosis and testing studies on internet addiction, 22 pictures were selected from the used pictures of initial sandplay in existing research results of initial sandplay of Chinese young Internet addicts. 54 normal adolescents were recruited to evaluate the valence of the pictures on a nine-point scale in terms of clarity, pleasure and arousal. Results were shown that there were no significant differences between addiction pictures and non-addiction pictures in clarity, while there were significant differences in pleasure and arousal, as the scores of non-addiction pictures were higher. Correlation analysis indicated that there was obvious positive correlation among clarity, pleasure and arousal of addiction pictures & non-addiction pictures. The coefficients of internal consistency reliability and split-half reliability of 22 pictures’ scores exhibited both over 0.90. ISPSCYIA has proved typical and distinctive through valence assessment, which could be preliminarily applied to measure the characteristics of Chinese adolescents’ internet addiction.
文摘The present study aimed to examine the effectiveness of mindfulness therapy in controlling under treatment addicts’ drug cravings. This was a quasi-experimental study with pretest and posttest. The sample of this study included 30 under treatment male addicts whom were selected through applying random sampling method and were placed in two groups, experimental and control. After holding a preliminary session aiming at aiding the experimental group to become familiar with the procedure, 8 sessions of the mindfulness-based therapy were administered. Assessment tools were Craving Beliefs Questionnaire (CBQ) and the Depression Anxiety Stress Scale (DASS-21). After calculating mean and standard deviation, the obtained data were analyzed using covariance. The results indicated that the mindfulness therapy was significantly effective in controlling drug cravings, decreasing stress, anxiety, and depression of under treatment addicts (p < 0.05).
文摘Objective: One of the common misinterpretation be- liefs in some societies (especially eastern communities) is the using of opium can reduce serum glucose and lipids. Opium is a derivative from a plant family called Papaveracea and contains almost 80 types of alkaloids. Drug addiction causes physiological dependency and its withdrawal lead to some disorders. The aim of this study was to determine the effects of opium consumption and its withdrawal on some blood biochemical factors in addicted people. Methods: We enrolled fifty-six opium addicted people according to the especial criteria to this study. Biochemical blood parameter levels such as fasting blood sugar (FBS), urea, Creatinine (Cr), Aspartate transaminase (AST), Alanine transaminase (ALT) and Alkaline phosphatase (ALP) enzymes levels were measured and urine analysis was also performed before and 3 months after withdrawal. Data were analyzed by using SPSS software version 18 and a P < 0.05 was considered as significant. Results: our finding showed that opium withdrawal reduces FBS and increases AST but these changes were not significant. Nevertheless opium withdrawal significantly increased blood urea level (P < 0.0001). We didn’t find any significant difference in Cr, ALP, AST and Urea specific gravity (SG). Conclusion: According to the results of the current study we can concluded that opium increases FBS, which is in contrast to the most previous studies and withdrawal has opposite effects.

文摘Inhibitory control dysfunction is regarded as a core feature in addicts.The major objective of this study was to explore the time course of response inhibition in chronic heroin addicts and provide the neurophysiological evidence of their inhibitory control dysfunction.The amplitudes and latencies of ERP components were studied in fourteen heroin addicts(mean duration of heroin use being(13.54±5.71) years(Mean±SD),average abstinence being((4.67±6.44) months)) and fourteen matched healthy controls with a visual Go/Nogo task.Our results showed that heroin addicts demonstrated significantly larger Go-N2 amplitudes which results in a decreased N2 Go/Nogo effect,but no statistically significant differences were found between heroin addicts and controls in P3.The ERP data suggest that fronto-central areas of heroin addicts were impaired during the inhibition process(200-300 ms) and over-activated to targets.The impaired early process might reflect an abnormal conflict monitoring process in heroin addicts.These results consolidate the inhibitory control dysfunction hypothesis in chronic heroin users.

文摘Objectives:The addiction of the student population to short-form video platforms such as TikTok(Douyin)is becoming increasingly apparent and is rapidly expanding.This emerging addiction is also believed to have negative impacts on students’academic,social,and emotional well-being.Consequently,video addiction has become an important public health issue on campuses around the world.Therefore,this study aimed to investigate the relationship between two types of TikTok addiction(video and live streaming)and social and emotional learning(SEL),including self-awareness,self-management,social awareness,relationship skills,and responsible decision-making.Methods:Previous research has indicated that some students at vocational colleges become addicted to short-form videos.Accordingly,this study employed a snowball sampling method to survey students at vocational institutions across China.A total of 563 valid responses were obtained,yielding an effective response rate of 84.66%.The mean age of participants was 20.20 years old(SD=1.36).Data were validated with structural equation modeling.Results:Results showed that both video content addiction and live-streaming content addiction negatively correlatedwith all five dimensions of SEL.This also represents that all 10 hypotheses are valid and significant at p<0.001.Theeffect sizes ranged from 0.48 to 0.54,which represents larger effect sizes.Notably,TikTok addiction showed the strongest explanatory power for self-awareness.This indicates that higher levels of addiction to either video or live-streaming content are associatedwith poorer performance across all facets of social and emotional learning,including self-awareness,emotion regulation,interpersonal relationships,sense of responsibility,and empathy.Conclusion:This study found that TikTok addicts entered a state of ego depletion due to impaired self-regulation.This depletion then caused their subsequent self-control efforts during learning to fail.Our results also support the ego depletion theory,which posits that engaging in self-regulatory behaviors consumes limited self-control resources and can trigger a range of complex cognitive,emotional,and behavioral problems.This result also draws attention to the negative consequences of excessive use of short videos for social awareness and emotional performance.

文摘Objectives:Short video addiction has emerged as a significant public health issue in recent years,with a growing trend toward severity.However,research on the causes and impacts of short video addiction remains limited,and understanding of the variable“TikTok brain”is still in its infancy.Therefore,based on the Stimulus-Organism-Behavior-Consequence(SOBC)framework,we proposed six research hypotheses and constructed a model to explore the relationships between short video usage intensity,TikTok brain,short video addiction,and decreased attention control.Methods:Given that students are considered a high-risk group for excessive short video use,we collected 1086 valid participants from Chinese student users,including 609 males(56.1%)and 477 females(43.9%),with an average participant age of 19.84 years,to test the hypotheses.Results:(1)Short video usage intensity was positively related to short video addiction,TikTok brain,and decreased attention control;(2)TikTok brain was positively related to short video addiction and decreased attention control;and(3)Short video addiction was positively related to decreased attention control.Conclusions:These findings suggest that although excessive use of short video applications brings negative consequences,users still spend significant amounts of time on these platforms,indicating a need for strict self-regulation of usage time.

文摘Overeating is a risk factor and a management challenge in adiposity-based chronic disease(ABCD).Acupuncture has shown high safety and reliable clinical evidence in addressing overeating,and it is the promising potential non-pharmacological intervention.However,the mechanism underlying its effects has not been sufficiently summarized.The addiction model offers a framework to elucidate the mechanism of this aberrant eating behavior and provides novel perspectives and breakthrough points for optimizing clinical acupuncture strategies in ABCD management.In the paper,through analyzing domestic and in-ternational relevant findings,the characteristics of overeating based on food addiction,the relationship between overeating and ABCD,and the potential effect mechanisms of acupuncture for FA have been re-viewed and summarized.Including adaptive balance of transmitters and hormones,functional networks,periphery-central connection,and cross-system interaction.In future studies,the maturely-developed ad-diction research methods should be adopted to deepen the exploration on the mechanism of acupuncture effect,addiction medicine should be leveraged to shatter the cognitive barriers surrounding acupuncture’s role in mind-body regulation for ABCD treatment,and the prevention and treatment of overeating via acupuncture should be organically integrated into multidisciplinary management strategies.

文摘Understanding the cellular mechanisms of drug addiction remains a key task in current brain research.While neuron-based mechanisms have been extensively explored over the past three decades,recent evidence indicates a critical involvement of astrocytes,the main type of non-neuronal cells in the brain.In response to extracellular stimuli,astrocytes modulate the activity of neurons,synaptic transmission,and neural network properties,collectively influencing brain function.G protein-coupled receptors(GPCRs)expressed on astrocyte surfaces respond to neuron-and environment-derived ligands by activating or inhibiting astrocytic signaling,which in turn regulates adjacent neurons and their circuitry.In this review,we focus on the dopamine D1 receptors(D1R)and metabotropic glutamate receptor 5(mGLUR5 or GRM5)—two GPCRs that have been critically implicated in the acquisition and maintenance of addiction-related behaviors.Positioned as an introductory-level review,this article briefly discusses astrocyte biology,outlines earlier discoveries about the role of astrocytes in substance-use disorders(SUDs),and provides detailed discussion about astrocytic D1Rs and mGLUR5s in regulating synapse and network functions in the nucleus accumbens(NAc)—a brain region that mediates addictionrelated emotional and motivational responses.This review serves as a stepping stone for readers of Engineering to explore links between astrocytic GPCRs and drug addiction and other psychiatric disorders.

文摘Persistent and maladaptive drug-related memories represent a key component in drug addiction.Converging evidence from both preclinical and clinical studies has demonstrated the potential efficacy of the memory reconsolidation updating procedure(MRUP),a non-pharmacological strategy intertwining two distinct memory processes:reconsolidation and extinction—alternatively termed“the memory retrieval-extinction procedure”.This procedure presents a promising approach to attenuate,if not erase,entrenched drug memories and prevent relapse.The present review delineates the applications,molecular underpinnings,and operational boundaries of MRUP in the context of various forms of substance dependence.Furthermore,we critically examine the methodological limitations of MRUP,postulating potential refinement to optimize its therapeutic efficacy.In addition,we also look at the potential integration of MRUP and neurostimulation treatments in the domain of substance addiction.Overall,existing studies underscore the significant potential of MRUP,suggesting that interventions predicated on it could herald a promising avenue to enhance clinical outcomes in substance addiction therapy.

文摘Drug addiction, a disorder characterized by chronic relapse and compulsive drug use, poses a significant threat to public safety and human health. Addictive substances can be categorized as natural, semi-synthetic, or synthetic based on their origin. Additionally, they can be classified into three groups according to their pharmacological targets: opioids, hallucinogens, and cannabinoids that act on G-protein-coupled receptors (GPCRs);alcohols, nicotine, ketamine, barbiturates, and benzodiazepines (BDZs) that affect ligand-gated ion channel-type receptors;and psychostimulants that interact with monoamine transporters. Current treatments for drug addiction primarily include substitution therapy and non-pharmacological approaches. However, these methods have limitations, particularly in addressing the underlying causes of relapse. Several drugs in clinical trials have demonstrated potential therapeutic effects for addiction to opioids, heroin, cocaine, and other substances. This review examines the origins and pharmacological mechanisms of addiction to naturally-derived psychoactive substances (NPS) and provides an overview of recent advancements in pharmacotherapy for drug addiction.
