Abstract
Background: The primary risk of HIV transmission in China has shifted from injecting drug use (IDU) to sexual contact since 2006. We evaluated the prevalence trends of HIV, hepatitis C virus (HCV), syphilis, and sexual and drug use behaviors among drug users. Methods: People who use drugs participated in any of four rounds of cross-sectional surveys during 2010-2017 in Chongqing. Participants were tested for HIV, HCV, and syphilis. Questionnaire interviewing was conducted to collect behavioral information. Chi-square and trend tests were employed to assess the changes in diseases and behaviors over time. Results: A total of 8,171 people who inject drugs (PWID) and 5,495 non-injection drug users (NIDU) were included in the analyses. HIV prevalence among PWID in four rounds of the survey in 2010-11, 2012-13, 2014-15, and 2016-17 was 11.5%, 9.7%, 6.5%, and 6.9%, and among NIDU, 2.4%, 1.4%, 2.1% and 2.6%, respectively. HCV prevalence among PWID was 83.5%, 85.2%, 67.1% and 79.7% (P < 0.001), and among NIDU, 22.2%, 10.8%, 13.4% and 14.8%, (P < 0.001). Conclusions: The declining HIV and HCV prevalence among PWID is coincident with declining risky drug use behaviors. Tailored disease prevention and interventions targeting PWID and NIDU are needed.

Mavragani A, Bradley H, Wang Z, Ma M, Zhang B, Jia Z. Comparison of the Users' Attitudes Toward Cannabidiol on Social Media Platforms: Topic Modeling Study. JMIR Public Health Surveill 2023; 9:e34132. [PMID: 36630175 PMCID: PMC9878368 DOI: 10.2196/34132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 05/14/2022] [Accepted: 11/25/2022] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND As one of the major constituents of the cannabis sativa plant, cannabidiol (CBD) is approved for use in medical treatment and cosmetics because of its potential health benefits. With the rapid growth of the CBD market, customers purchase these products, and relevant discussions are becoming more active on social media. OBJECTIVE In this study, we aimed to understand the users' attitudes toward CBD products in various countries by conducting text mining on social media in countries with different substance management policies. METHODS We collected posts from Reddit and Xiaohongshu, conducted topic mining using the latent Dirichlet allocation model, and analyzed the characteristics of topics on different social media. Subsequently, a co-occurrence network of high-frequency keywords was constructed to explore potential relationships among topics. Moreover, we conducted sentiment analysis on the posts' comments and compared users' attitudes toward CBD products on Reddit and Xiaohongshu using chi-square test. RESULTS CBD-related posts on social media have been rapidly increasing, especially on Xiaohongshu since 2019. A total of 1790 posts from Reddit and 1951 posts from Xiaohongshu were included in the final analysis. The posts on the 2 social media platforms, Reddit and Xiaohongshu, were categorized into 7 and 8 topics, respectively, by the latent Dirichlet allocation model, and these topics on the 2 social media were grouped into 5 themes. Our study showed that the themes on Reddit were mainly related to the therapeutic effects of CBD, whereas the themes on Xiaohongshu concentrated on cosmetics, such as facial masks. Theme 2 (CBD market information) and theme 3 (attitudes toward CBD) on Reddit had more connections with other themes in the co-occurrence network, and theme 3 and theme 1 (CBD therapeutic effects) had a high co-occurrence frequency (22,803/73,865, 30.87%). Meanwhile, theme 1 (CBD cosmetics) on Xiaohongshu had various connections with others (169,961/384,575, 44.19%), and the co-occurrence frequency of theme 4 (CBD ingredients) and theme 1 was relatively prominent (27,128/49,312, 55.01%). Overall, users' comments tended to be positive for CBD-related information on both Reddit and Xiaohongshu, but the percentage was higher on Xiaohongshu (82.25% vs 86.18%; P<.001), especially in cosmetics and medical health care products. CONCLUSIONS The CBD market has grown rapidly, and the topics related to CBD on social media have become active. There are apparent differences in users' attitudes toward CBD in countries with different substance management policies. Targeted CBD management measures should be formulated to suit the prevalence of CBD use of each country.

Normalization of the H3K9me2/H3K14ac-ΔFosB pathway in the nucleus accumbens underlying the reversal of morphine-induced behavioural and synaptic plasticity by Compound 511. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 108:154467. [PMID: 36252464 DOI: 10.1016/j.phymed.2022.154467] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 09/10/2022] [Accepted: 09/18/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Although opioid agonist-based treatments are considered the first-line treatment for opioid use disorders, nonopioid alternatives are urgently needed to combat the inevitable high relapse rates. Compound 511 is a formula derived from ancient traditional Chinese medical literature on opiate rehabilitation. Previously, we observed that Compound 511 could effectively prevent the acquisition of conditioned place preference (CPP) during early morphine exposure. However, its effects on drug-induced reinstatement remain unclear. PURPOSE This study aims to estimate the potential of Compound 511 for the therapeutic intervention of opioid relapse in rodent models and explore the potential mechanisms underlying the observed actions. STUDY DESIGN/METHODS The CPP and locomotor sensitization paradigm were established to evaluate the therapeutic effect of Compound 511 treatment on morphine-induced neuroadaptations, followed by immunofluorescence and western blot (WB) analysis of the synaptic markers PSD-95 and Syn-1. Furthermore, several addiction-associated transcription factors and epigenetic marks were examined by qPCR and WB, respectively. Furthermore, the key active ingredients and targets of Compound 511 were further excavated by network pharmacology approach and experimental validation. RESULTS The results proved that Compound 511 treatment during abstinence blunted both the reinstatement of morphine-evoked CPP and locomotor sensitization, accompanied by the normalization of morphine-induced postsynaptic plasticity in the nucleus accumbens (NAc). Additionally, Compound 511 was shown to exert a selectively repressive influence on morphine-induced hyperacetylation at H3K14 and a reduction in H3K9 dimethylation as well as ΔFosB activation and accumulation in the NAc. Finally, two herbal ingredients of Compound 511 and six putative targets involved in the regulation of histone modification were identified. CONCLUSION Our findings indicated that Compound 511 could block CPP reinstatement and locomotor sensitization predominantly via the reversal of morphine-induced postsynaptic plasticity through epigenetic mechanisms. Additionally, 1-methoxy-2,3-methylenedioxyxanthone and 1,7-dimethoxyxanthone may serve as key ingredients of Compound 511 by targeting specific epigenetic enzymes. This study provided an efficient nonopioid treatment against opioid addiction.

Abstract
Background Methamphetamine is the most prevalent drug in the mainland of China, yet few studies on the non-medical use of methamphetamine nationwide have been conducted. This study aimed to examine the trends in the prevalence of non-medical methamphetamine use and to explore the flow pattern of internal migrant methamphetamine users in the mainland of China. Methods Data were extracted from the National Dynamic Management and Control Database for Drug Users (NDMCD). Joinpoint regressions were used to examine trends in the prevalence and population size of methamphetamine use. Results A total of 1,821,468 methamphetamine use cases registered in NDMCD from 2006 to 2015 were identified. The number of methamphetamine use cases presented an increasing trend in all age subgroups, and among them, the elderly increased the fastest [annual percent change (APC2006−2015), 122.9; 95% CI, 113.0–133.3; p < 0.001]. The prevalence of methamphetamine use increased from 4.69 per 100,000 population in 2008 to 45.38 per 100,000 population in 2015 (APC2008−2015, 36.1; 95% CI, 31.9–40.6; p < 0.001). The regions of the Pearl River Delta, Yangtze River Delta, and Beijing-Tianjin-Hebei Urban Agglomeration absorbed over 96% of all internal migrant methamphetamine use cases, and the number of migrant methamphetamine use cases presented increased trends in these three regions. Conclusions The increasing trends in methamphetamine use have become a threat to all age groups in China. Substance use prevention programs should focus on internal migrant drug users, especially in economically developed regions.

Abstract
Introduction Oleanolic acid (OA) has been shown to be useful for the treatment of mental disorders. Methods In this study, we investigated the effects of OA in animal models of spontaneous withdrawal and naloxone-precipitated withdrawal and evaluated the effects of OA on the acquisition, extinction, and reinstatement of morphine-induced conditioned place preference (CPP). Results OA significantly improved symptoms of withdrawal, and significantly reduced the acquisition and reinstatement of morphine-induced conditioned place preference. Moreover, OA significantly reduced the serum content of 5-hydroxy tryptamine (5-HT) and dopamine (DA) in a dose-dependent manner, and reduced norepinephrine (NE) and 5-HT content in the frontal cortex (PFC), while significantly increasing endorphin content in rats. OA also significantly reduced serum DA content in mice. Conclusion These results indicate that OA can improve the withdrawal symptoms of rats and mice by regulating the DA system and suggest that OA may be useful in treatment of morphine addiction.

Abstract
Background: E-cigarette use has spread rapidly and widely among youth, to an extent that has surprised some researchers.Objectives: We suggest that this surprise is owing to a particular limitation in the dominant models of addiction - namely, a strong focus upon addictive substances as cause. We argue that the phenomenon at hand is easier to comprehend when less attention is placed upon preventing the use of specific substances and more upon what we identify as structural susceptibility to addiction instead.Results: Drawing upon neurobiology, history, public health theory, and social theory, we re-conceive addictive substances as mechanisms of escape from social structures that predispose whole societies to addiction.Conclusions/Importance: We argue that the surge in youth e-cigarette use in particular, as well as the phenomenon of addiction in general, are easier to comprehend if models of addiction are expanded to conceptualize the problem in its wider dimensions. We invite addictions researchers to join us in expanding the field's analytical view.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17155483. [PMID: 32751337 PMCID: PMC7431999 DOI: 10.3390/ijerph17155483] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 07/17/2020] [Accepted: 07/21/2020] [Indexed: 12/31/2022]
Abstract
Background: Heavy drug users was a global consensus high-risk population of HIV infection. However, the specific impact of drug on HIV infection has not yet been established. Depressants and stimulants were most widely used drugs in mainland China, and mix use of the two drugs was also serious. We assessed the HIV infection rate and trends in heavy drug users by analyzing data from the National Dynamic Management and Control Database for Drug Users (NDMCDDU). Methods: All heavy drug users with HIV test results in NDMCDDU from 2008 to 2016 were grouped into depressants only group (DOG), stimulants only group (SOG), and both depressants and stimulants group (DSG). We used joinpoint regression to examine trends of HIV infection rates. Multivariable logistic regression was used to examine factors related to HIV infection. Results: A total of 466,033 heavy drug users with 9522 cases of HIV infection were included in this analysis. HIV infection rate was estimated at 2.97% (95% CI 2.91–3.04%) of 265,774 users in DOG, 0.45% (95% CI 0.42–0.49%) of 140,895 users in SOG, and 1.65% (95% CI 1.55–1.76%) of 59,364 users in DSG. In DOG, a U-shaped curve of HIV infection rate decreased from 3.85% in 2008 to 2.19% in 2010 (annual percent change (APC) −12.9, 95% CI −19.3–−6.0, p < 0.05), then increased to 4.64% in 2016 (APC 8.3, 95% CI 6.1–10.4, p < 0.05) was observed. However, SOG and DSG showed consistent increases from 0.15% in 2008 to 0.54% in 2016 (APC 8.2, 95% CI 4.8–11.8, p < 0.05) and from 0.78% in 2008 to 2.72% in 2016 (APC 13.5, 95% CI 10.7–16.4, p < 0.05), respectively. HIV infection rate of DOG in the southwest region presented a U-shaped trend. All groups showed significant increases in HIV infection in east and central regions. Conclusions: The U-shaped curve for HIV infection rate among DOG users and consistent increases among SOG and DSG users implies drug abuse is still a critical focus of HIV infection in China. It is urgently needed to reassess the effectiveness of current strategies on HIV prevention and control among drug users.

Abstract
BACKGROUND Opioid use disorder (OUD) causes substantial public health and social problems worldwide. Poly-drug use is common in people with OUD and increases morbidity and mortality. Investigation of the patterns and characteristics of poly-drug use of prescription medicine among opioid users is needed to develop appropriate prevention and intervention strategies. OBJECTIVES To estimate the prevalence of poly-drug use of prescription medicine among people with OUD in China using meta-analysis. METHODS We searched relevant epidemiological studies published before February 2017 in English and Chinese databases. The quality of included studies was assessed using the Agency for Healthcare Research and Quality scale. The pooled prevalences of prescription medicine use among people with OUD were estimated. RESULTS We included 80 eligible studies in the meta-analysis. The main prescription medicines were benzodiazepines (BZDs) and prescription opioid analgesics. The pooled prevalence of unclassified BZDs and prescription opioids was 40.6% and 23.2%, respectively. Diazepam was the most frequently co-used BZD (32.6%), followed by triazolam (32.1%), and estazolam (9.2%). Tramadol was the most commonly used prescription opioid (27.3%), followed by methadone (16.8%), buprenorphine (12.6%), pethidine (8.9%), morphine (6.5%), dihydroetorphine (3.9%), and codeine-containing cough syrup (3.7%). BZDs were mainly used for self-medication (56.1%), whereas prescription opioids were primarily coused for nonmedical purposes (69.4%). CONCLUSIONS The results demonstrate that prescription medicine use is widespread among opioid users in China. There needs to be more consideration of poly-drug use, and early interventions and management strategies are needed to prevent poly-drug use among opioid users in China.

Abstract
The methadone maintenance treatment (MMT) has been initiated in Wuhan, China since early 2006. To understand the social-demographic, behavioral, and infectious diseases characteristics of drug users enrolled in their first-ever-MMT between 2006 and 2015, a retrospective observational study was implemented to also provide evidence for health policy-decisions to reduce harm and control disease. Pearson chi-square tests and t-tests were used to assess significant differences between two 5-year periods, 2006-2010 and 2011-2015. We observed increases in the mean age (38.65 vs. 42.43 years, P < 0.001), mean age of initial opioid drug use (28.18 vs. 31.07 years, P < 0.001), employment (11.9% vs. 30.7%, P < 0.001), married/co-habiting (42.4% vs. 47.8%, P < 0.001), and declines in higher education level (93.6% vs. 84.8%, P < 0.001), injection (82.3% vs. 75.1%, P < 0.001), syringe sharing (27.7% vs. 9.9%, P < 0.001), HCV infection rates (72.9% vs. 70.5%, P = 0.017). The number of drug users enrolling each year reduced following a continuous rapid growth in the first 3 years. The findings imply for adjusting in treatment services and allocation of resources to respond to emerging trends. In addition, the data will also be helpful for identifying needs and getting a baseline insight of the social-demographic and behavioral characteristics of the opioid abusers in the area.

Abstract
To compare the effects of heroin and methamphetamine (METH) addiction on dopamine transporters (DATs) in the same dose and duration, we assessed DAT levels in the striatum by 99m Tc-TRODAT-1 single-photon emission computed tomography (SPECT) brain images in people with heroin and METH dependence. We recruited 21 healthy human controls, 23 heroin-dependent subjects and 25 METH abusers. The heroin- and METH-dependent subjects exhibited negative urine toxicology after undergoing physiological detoxification. All subjects underwent SPECT brain imaging, and specific tracer uptake ratios (SURs) were assessed bilaterally in the regions of interest. A significant SUR reduction in heroin-dependent subjects and METH-dependent subjects compared with healthy controls was found in the left striatum, right striatum, left caudate nucleus, right caudate nucleus, left putamen and right putamen. There were no significant differences in the heroin group and METH group for the left striatum, right striatum, left caudate nucleus, right caudate nucleus, left putamen and right putamen. The scores of craving, HAMA (Hamilton Anxiety Rating Scale), in heroin abusers were lower than in the METH abusers. Our results show that people with heroin and METH dependence who are currently abstinent had lower DAT levels in the striatum than healthy controls. There were no differences in striatal DAT in heroin and METH users. These results suggest that chronic heroin and METH abuse appears to produce similar effects in striatal DAT in humans. METH users may have more serious craving and anxiety symptoms than heroin users with prolonged abstinence.

Abstract
Previous studies demonstrated that histone acetylation modulated the transcription of associated gene expression and thus contributed to the persistence of addictive behaviors and neuroplasticity. Nonetheless, the roles of histone acetylation in distinct phases of methamphetamine (METH)-induced conditioned place preference (CPP) remain unclear. The current study examines the effects of the histone deacetylases (HDACs) inhibitor sodium butyrate (NaB) on the acquisition, extinction, and reinstatement of METH-induced CPP in mice. Our results showed that 1 mg/kg METH induced CPP in mice after four conditioning sessions. METH-induced CPP was extinguished after three extinction training sessions and could be triggered by the same dose (1 mg/kg) of METH on the reinstatement test day. Meanwhile, NaB (400 mg/kg) per se had no effect on the natural preference of mice, but injections of NaB during the conditioning and extinction phases facilitated the acquisition and extinction of METH-induced CPP, respectively. Additionally, although the effect of a single NaB injection prior to the trigger of CPP reinstatement was not observed, repeated NaB injections during the extinction phase totally blocked the reinstatement of METH-induced CPP. Taken together, our results suggested a specific effect of histone acetylation on modulating distinct phases of METH-induced CPP and that treatment of NaB during the extinction phase not only produced beneficial effects on eliminating already established CPP but also blocked the reinstatement of METH-induced CPP. © 2016 Wiley Periodicals, Inc.

Analysis of Risk Factors Associated with the Development of Hepatocellular Carcinoma in Chronic HBV-Infected Chinese: A Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2016; 13:ijerph13060604. [PMID: 27322300 PMCID: PMC4924061 DOI: 10.3390/ijerph13060604] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/15/2016] [Revised: 06/12/2016] [Accepted: 06/14/2016] [Indexed: 12/13/2022]
Abstract
Hepatitis B virus (HBV) infection is a major risk factor for the development of hepatocellular carcinoma (HCC) in China. At present, there still are 9.3 million chronic HBV-infected Chinese. Numerous studies have explored the association between possible factors and hepatocellular carcinoma risk, however, the results remains inconsistent. Therefore, we did this pooled analysis so as to get a precise result. Here, we took the chronic HBV-infected Chinese as the object. We systematically searched for studies evaluating whether the proposed factors changed HCC risk in PubMed, Chinese National Knowledge Infrastructure, VIP database and Wanfang data. Odds ratios (OR) with 95% confidence intervals (CI) were calculated by Review Manager 5.0 and publication bias was determined by Begg’s test and Egger’s test. In total, 3165 cases and 10,896 controls from 27 studies were included in this meta-analysis. Our results showed that pooled OR with 95% CI for each of the factors investigated were: non-antiviral treatment 2.70 (2.01, 3.62), high HBV DNA levels 2.61 (1.73, 3.94), alcohol consumption 2.19 (1.53, 3.13), a family history of HCC 3.58 (2.53, 5.06) and male gender 2.14 (1.68, 2.73), respectively. Our meta-analysis supports that high HBV DNA levels, non-antiviral treatment, alcohol consumption, a family history of HCC and male gender contributed to the risk of hepatocellular carcinoma in chronic HBV-infected Chinese from currently available evidence. Given the high prevalence of the non-antiviral treatment and alcohol drinking, behavior interventions for the two factors should be tackled first.

Abstract
BACKGROUND Methadone maintenance treatment (MMT) reduces the harms of opioid use disorder and is being rapidly scaled-up in China. This study evaluated the real-world implementation of MMT system in Wuhan, China. METHODS Data extracted from electronic medical records collected in 2010 on 8811 patients were used to compute for each patient indices of the prescribed and consumed daily methadone doses, an adherence index, dose adjustments following missed doses, the rates of opiate positive urine tests, self-reported drug use, injection drug use (IDU), and the duration of MMT exposure. FINDINGS The modal daily doses prescribed were 60 mg and above for 68.5% of patients. Adherence was variable: 51% of patients attended less than 60% and 26% attended 80-100% of their treatment days; and patients with long MMT exposure had significantly higher adherence rates than patients with short MMT exposure. The differences between doses dispensed immediately before and after the interruption in dosing days ranged from 0 to 7 mg, independently of the length of the interruption or the prescribed dosing level. The overall rate of opiate positive tests was 20%; 45% of patients had at least one opiate positive test; 29% reported past month drug use and 53% of them reported past month IDU. Adherence and MMT exposure duration correlated significantly with the proportion of opiate negative urine tests (r=0.355, p<0.001; r=0.351, p<0.001, respectively). Treatment for males and females was comparable. CONCLUSIONS Provision of safe methadone dosing after absences and improving daily attendance are identified as priority improvement areas.

Abstract
Addiction to psychostimulants has been considered as a chronic psychiatric disorder characterized by craving and compulsive drug seeking and use. Over the past two decades, accumulating evidence has demonstrated that repeated drug exposure causes long-lasting neurochemical and cellular changes that result in enduring neuroadaptation in brain circuitry and underlie compulsive drug consumption and relapse. Through intercellular signaling cascades, drugs of abuse induce remodeling in the rewarding circuitry that contributes to the neuroplasticity of learning and memory associated with addiction. Here, we review the role of the extracellular signal-regulated kinase (ERK), a member of the mitogen-activated protein kinase, and its related intracellular signaling pathways in drug-induced neuroadaptive changes that are associated with drug-mediated psychomotor activity, rewarding properties and relapse of drug seeking behaviors. We also discuss the neurobiological and behavioral effects of pharmacological and genetic interferences with ERK-associated molecular cascades in response to abused substances. Understanding the dynamic modulation of ERK signaling in response to drugs may provide novel molecular targets for therapeutic strategies to drug addiction.

Abstract
BACKGROUND Heroin has emerged as the primary drug of concern in China, with as many as three million contemporary users. Once a Chinese citizen has been identified by Chinese law enforcement as a 'drug addict', that individual is 'registered' in an official government tracking system for the rest of his or her life, independent of verified rehabilitation and recovery. Most of what is known about heroin users in China is based on studies of registered heroin users participating, often involuntarily, in government-sponsored treatment. METHODS Using Grounded Theory Methodology, we collected and analyzed in-depth interviews of heroin users voluntarily seeking treatment at a new, non-government-sponsored, for-profit, addiction treatment hospital in Beijing, China. RESULTS We identified three major themes among our participants: (1) intense social stigma towards individuals with drug addiction; (2) a desire for anonymous, confidential treatment to avoid social stigma and the loss of personal freedom that accompanies participation in government-sponsored treatment; and (3) a deep mistrust of government-sponsored treatment and a search for more effective alternatives. CONCLUSION Despite a desire for treatment, our subjects were reluctant to access government-sponsored treatment facilities because of fear of a stigmatized identity, fear of loss of personal freedom, and lack of faith in the efficacy and safety of government-sponsored treatments. Their willingness to pay cash at a new, non-government-sponsored, addiction treatment facility illustrates the lengths to which they will go to remain 'unregistered' and to discover better alternatives. That the Chinese government allows such facilities to operate outside of government surveillance suggests a new openness to alternative options to combat China's rising drug epidemic. The efficacy of these alternative options, however, remains in question.

Abstract
BACKGROUND Illicit drug use/dependence has been recognized as a major problem. Clinical studies demonstrate that poor sleep quality is associated with increased frequency of drug use and relapse. However, few studies have addressed the issue of sleep quality among illicit drug dependent subjects. METHODS This cross-sectional study explored sleep quality in drug dependent subjects in China. We studied 2178 illicit drug dependent subjects from drug rehabilitation centres in Changsha and 2236 non-drug-using subjects, all of whom completed the self-report Pittsburgh Sleep Quality Index (PSQI). RESULTS We found that the prevalence of sleep disturbance was much higher in drug users (68.5%, PSQI >5; specifically, 80.24% in heroin users, 54.16% in methamphetamine users and 81.98% in ketamine users with PSQI >5) than non-users (26.4%, PSQI >5). Drug users had approximately twice the sleep latency than nondrug users (37.7 minutes V.S 18.4 minutes). Although drug users and non-users reported similar sleep duration (about 7.4 hours), drug users showed poorer subjective sleep quality and habitual sleep efficiency. They reported more sleep disturbance and need for sleep medications, more daytime dysfunction and poorer subjective sleep quality compared with nondrug users. The total PSQI score positively correlated with the duration of drug use (rp = 0.164, p < 0.001). We also found a link between sleep problems and cigarette smoking, alcohol drinking, and duration of drug use. CONCLUSIONS Poor sleep quality is common among illicit drug dependent subjects. Long-term substance users had more sleep problems. Future research aiming at quantifying the benefits of treatment interventions should not neglect the influence of sleep problems. Gaining more insight into the impact of sleep quality on the addiction treatment could also help to target future intervention measures more effectively.

Abstract
BACKGROUND AND OBJECTIVES Amphetamine-type stimulants (ATS) have quickly spread and been widely abused in many parts of the world, particularly in China. This review focuses on and describes the epidemiological trends and the advances of treatments of ATS in China. METHODS A descriptive study based on literature identified from searches of the China National Knowledge Infrastructure (1979-2013), PubMed databases, hand-picked references, and online references with emphasis on epidemiology, treatment and traditional Chinese medicine. This review covers some traditional Chinese treatments and their complementary Western approaches. RESULTS AND CONCLUSIONS The epidemiological trends of ATS in China have led to its being 2.2 times the rate of morphine abuse and second only to marijuana abuse. The treatment programs in China have used traditional herbal approaches as well as acupuncture, often in combination with Western medications such as fluoxetine for depression associated with ATS abuse. Other herbal treatments have reversed the cardiac arrhythmias associated with ATS intoxication, and acupuncture has been used successfully for the protracted depressive and somatic symptoms of ATS withdrawal over a period of 3 months. SCIENTIFIC SIGNIFICANCE These traditional Chinese treatments may be increasingly available to the world, but will remain a consistent complementary therapy for ATS in China and the Far East, where ATS has become such a prevalent problem.

Abstract
Summary The importance of genetic factors in substance addiction has long been established. The rationale for this work is that understanding of the function of addiction genes and delineation of the key molecular pathways of these genes would enhance the development of novel therapeutic targets and biomarkers that could be used in the prevention and management of substance abuse. Over the past few years, there has been a substantial increase in the number of genetic studies conducted on addiction in China; these studies have primarily focused on heroin, alcohol, and nicotine dependence. Most studies of candidate genes have concentrated on the dopamine, opioid, and serotonin systems. A number of genes associated with substance abuse in Caucasians are also risk factors in Chinese, but several novel genes and genetic risk factors associated with substance abuse in Chinese subjects have also been identified. This paper reviews the genetic studies of substance abuse performed by Chinese researchers. Genotypes and alleles related to addictive behavior in Chinese individuals are discussed and the contributions of Chinese researchers to the international corpus of knowledge about the genetic understanding of substance abuse are described.

Abstract
MicroRNA (miRNA)-related single nucleotide polymorphisms (miR-SNPs) can affect cancer development, treatment efficacy and patients prognosis. We examined 6 miR-SNPs in miRNA processing machinery genes including exportin 5 (XPO5) (rs11077), Ran-GTPase (RAN) (rs14035), Dicer (rs3742330), Trinucleotide Repeat Containing 6B (TNRC6B) (rs9623117), GEMIN3 (rs197412), GEMIN4 (rs2740348) in 108 surgically resected HCC patients and evaluated the impact of these miR-SNPs on HCC outcome. Among the 6 SNPs, only the A/A genotype of rs11077 located in XPO5 3'UTR was identified to associated independently with worse survival in HCC patients by multivariate analysis with relative risk, 0.395; 95% CI, 0.167-0.933; p = 0.034. This is the first study reporting that polymorphisms related to miRSNPs have prognostic value in hepatocellular carcinoma and identify the A/A genotype of rs11077 SNP site located in XPO5 3'UTR can help to predict worse prognosis in patients.

Abstract
PURPOSE Examine the severity of club drug dependence and perceived need for treatment, and further identify their determinants among a sample of club drug users in Shanghai, China. METHODS Two hundred and seventy-six club drug users were recruited using respondent-driven sampling (RDS). Severity of dependence on club drugs was measured using the Severity of Dependence Scale (SDS). RESULTS 69.9% reported dependence on club drugs (i.e., SDS ≥ 4) and 36.6% reported severe dependence (i.e., SDS ≥ 6). One-eighth (12.7%) perceived need for drug treatment. Severe dependence on club drugs was more likely among those who reported recent use of ecstasy and those who had more depressive symptoms, but less likely among those reporting recent use of methamphetamine. Perceived need for treatment was more likely among those who lived with a spouse or boy/girlfriend, but less likely among those had prior drug treatment experience and more severe club drug dependence. CONCLUSIONS Our findings suggest that educational activities should be implemented to raise public awareness about the powerful addictive properties of club drugs, along with efforts to reduce stigma towards drug abuse and psychiatric disorders. Programs to motivate drug users to seek treatment and encourage treatment linkage are urgently needed.

Abstract
BACKGROUND Over the past two decades, China has experienced a dramatic increase in methamphetamine (MA) abuse. This study examined gender-specific socio-demographic and clinical characteristics of MA use among Han Chinese, which has previously received little systematic study. METHODS This analysis described MA-related socio-demographic and clinical characteristics in a broad cross-sectional sample (n=1464; male/female=1185/279), and examined differences between males and females in MA use history, MA initiation, MA-related subjective feelings and behaviors, and withdrawal symptoms. RESULTS Most MA abusers (about 72%) were young (in their 20s or 30s), with women being 5 years younger than men on average. More males (33.2%) were married than females (21.9%). The average body mass index (BMI) was significantly lower in this MA abuser sample compared to the age-matched healthy controls. Moreover, the BMI of females was significantly lower than that of males. The laboratory tests showed that the blood levels of glucose, cholesterol and triglyceride were all significantly higher in males than females. Females used MA at a younger age compared to males. The most frequent route of MA use was smoking (90.9%). Males were more likely to use another drug, and more likely to be hospitalized. However, many characteristics and behaviors of MA use are similar for males and females, including the route, the dose and duration of MA use, and relapse status. CONCLUSION Although there were some male-female similarities in MA use parameters, significant differences do exist that may have implications for gender-specific research as well as for prevention and treatment strategies.

Abstract
BACKGROUND Pharmacologic therapies for maintenance treatment of heroin dependence have been used and studied widely. Systematic reviews have demonstrated the effectiveness of such therapies. Opium dependence is associated with less problems and impairments and is less likely to be used by injecting, with consequent reductions in risk of overdose and blood-borne diseases. Although it is a common substance use disorder in many countries, a systematic review of the literature is lacking on the maintenance treatment for opium dependence. OBJECTIVES To evaluate the effectiveness and safety of various pharmacological therapies on maintenance of opium dependence (alone or in combination with psychosocial interventions) compared to no intervention, detoxification, different doses of the same intervention, other pharmacologic interventions and any psychosocial interventions. SEARCH METHODS We searched the following sources up to February 2012: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, PsycINFO, regional databases (IMEMR and ASCI), national databases (Iranmedex and Iranpsych), main electronic sources of ongoing trials and reference lists of all relevant papers. Also, we contacted known investigators from some Asian countries to obtain details about unpublished trials. SELECTION CRITERIA Randomised controlled clinical trials (RCTs) comparing any maintenance pharmacologic intervention versus no intervention, other pharmacologic or non-pharmacologic intervention for opium dependence. DATA COLLECTION AND ANALYSIS Two reviewers assessed the risks of biases and extracted data, independently. MAIN RESULTS Three RCTs recruiting 870 opium dependents were included. The studies made different comparisons so it was not possible to pool data. Only retention rate was assessed by the studies. Two studies compared different doses of buprenorphine: in one study, 4 mg/day of buprenorphine was compared with doses of 2 mg/day and 1 mg/day and in another study, 8 mg/day of buprenorphine was compared with doses of 3 mg/day and 1 mg/day. Comparisons showed a statistically significant difference between groups; higher doses of buprenorphine increased the probability of retention in treatment. The studies had high risks of biases. In the third study, after a process of detoxification, baclofen (60 mg/day) was compared with placebo for maintenance treatment. The difference in retention rate between groups was high, but it was not statistically significant. AUTHORS' CONCLUSIONS It is not possible to conclude about the use of any kind of pharmacologic therapies for maintenance treatment of opium dependence.

Abstract
AIMS To investigate the incidence of dropout and the prevalence of poor adherence among newly admitted first-time clients of methadone maintenance treatment (MMT) clinics, and the associations between MMT-related misconceptions and these two treatment outcomes. DESIGN A cohort study (maximum follow-up period = 17.6 months) was conducted. SETTING Three of the nine MMT clinics in Guangzhou, China participated in the study. PARTICIPANTS The sample included 158 newly admitted first-time MMT clients. MEASUREMENTS Information collected included background characteristics, history of drug use, MMT-related misconceptions, dropout during the entire study period and poor adherence within the first 6 months since admission to MMT. FINDINGS Of all newly admitted MMT clients, 98.2% possessed at least one and 50.6% possessed all four types of MMT-related misconception; 51.3% had dropped out before the completion of the study [95% confidence interval (CI): 43.5-59.1%] and 62% exhibited poor adherence within the first 6 months since admission (95% CI: 54.2-69.6%). Adjusting for significant background variables, the number of misconceived responses predicted significantly both dropout [hazard ratio (HR) = 3.80 for two to three misconceived items, HR = 7.13 for four misconceived items, with zero to one misconceived item being the reference] and poor adherence within the first 6 months [relative risk (RR) = 4.13 for two to three misconceived items; RR = 4.40 for four misconceived items, with zero to one misconceived item being the reference. CONCLUSIONS Among opiate addicts in China prescribed methadone maintenance therapy for the first time, misconceptions about this medication are prevalent and are associated with poor adherence to the medication regimen and a high a rate of dropout from the treatment programme.

Abstract
The methadone maintenance treatment (MMT) program is scaling up in China, but little is known about drug users' cognitions of MMT. To investigate the prevalence and associated factors of MMT-related misconceptions, a totally of 300 newly admitted MMT users were interviewed in three MMT clinics in Guangzhou. Four statements were used to assess MMT-related misconceptions. The results showed that the majority of participants misconceived that MMT is intended primarily for detoxification (92.3%), that one could be completely detoxified and quit using methadone after using it for 2-3months (64.2%), that MMT is not a long-term or even lifetime treatment (77.9%); and that one should attempt to reduce its treatment dosage as methadone is harmful to one's health (84.3%); 48.5% of the respondents possessed all four types of misconceptions. Prior experience of methadone use in voluntary drug detoxification centers (OR=1.82 to 2.55, p<0.05) was associated with some misconception items, whilst being introduced by some peer drug users or community members to use MMT (versus not being introduced by anyone; OR=0.38 to 0.50, p<0.05), having taken up HIV voluntary counseling and testing prior to admission (OR=0.52, p<0.05), and a higher HIV-related knowledge level (OR=0.38, p<0.05) were associated with lower likelihoods for possessing some of the misconceptions. The findings suggested that MMT-related misconceptions were very prevalent among newly recruited MMT users in China. Misconceptions are potential factors causing drop-outs. Interventions targeting such misconceptions are greatly warranted.

Abstract
AIMS To compare characteristics and illicit drug abuse patterns among drug abusers in rural and urban areas of Hunan Province, China. MEASUREMENTS AND DESIGN: Data collected by public security bureau on newly registered drug abusers between 2005 and 2008 in five urban and five rural areas (n = 1639) were extracted anonymously and analyzed. SETTING AND PARTICIPANTS All newly registered drug users in urban (n = 812) and rural (n = 827) areas of Hunan Province were included. FINDINGS Drug users from the rural areas were younger [31 (6.6) versus 34 (8.0) years, P < 0.001], with a higher proportion of males (86% versus 82%, P < 0.05) or married (34% versus 27%, P < 0.01). Rural drug users reported an earlier onset of drug use [27 (5.9) versus 30 (7.9) years old, P < 0.001], were more likely to report heroin as their primary drug of abuse (53% versus 47%, P < 0.001) and had a lower prevalence of criminal activities (19% versus 31%, P < 0.001). Rural drug users were less likely to report needle sharing (1.8% versus 4.3%, P < 0.01), less likely to report being human immunodeficiency virus positive (0.8% versus 2.6%, P < 0.01) and less likely to report prior drug treatment participation (2.8% versus 6.8%, P < 0.001). CONCLUSIONS Drug abuse is a substantial problem in both urban and rural areas in China. The very low proportion of newly registered drug users reporting any prior drug abuse treatment points to the importance of expanding substance abuse treatments, especially in rural areas where treatment penetration is even lower than in urban areas.

Abstract
MicroRNAs (miRNAs) can bind to the 3'-untranslated regions (UTRs) of messenger RNAs, where they interfere with translation and thereby regulate cell differentiation, apoptosis and tumorigenesis. Genetic polymorphisms in the 3'-UTRs targeted by miRNAs alter the strength of miRNA binding in a manner that affects the behavior of individual miRNAs. The histone methyltransferase SET8 has been reported to methylate TP53 and regulate genomic stability. We analyzed a single-nucleotide polymorphism (rs16917496) within the miR-502 miRNA seed region for the 3'-UTR of SET8 in Chinese patients with hepatocellular carcinoma (HCC). The SET8 CC genotype was independently associated with longer postoperative survival in patients with HCC by multivariate analysis (relative risk, 0.175; 95% CI = 0.053-0.577; p = 0.004). The SET8 CC genotype was associated with reduced SET8 protein levels based on the immunostaining of 51 HCC tissue samples. We also found that the low SET8 levels were associated with longer HCC survival. Our data suggest that SET8 modifies HCC outcome by altering its expression, which depends, at least in part, on its binding affinity with miR-502. The analysis of genetic polymorphisms in miRNA binding sites can help to identify patient subgroups that are at high risk for poor disease outcomes.

Abstract
This pilot clinical trial evaluated whether the efficacy of methadone maintenance treatment (MMT) provided with limited psychosocial services is improved by the addition of manual-guided behavioral drug and HIV risk reduction counseling (BDRC). Heroin dependent individuals (n=37) enrolling in two MMT clinics in Wuhan, China, received standard MMT services, consisting of daily medication at the clinics and infrequent additional services on demand, and were randomly assigned to MMT only (n=17) or MMT with weekly individual BDRC (n=20) for 3 months. Participants were followed for six months from the time of enrollment (3 months active counseling phase and 3 months follow-up while treated with standard MMT). Primary outcome measures included reductions of HIV risk behaviors and illicit opiate use and treatment retention. Participants were 81% male; mean (SD) age 36.7 (7.2) years; there were no significant baseline differences between the two groups. Participants in MMT+BDRC achieved both greater reductions of HIV risk behaviors (p<0.01), as indicated by the scores on a short version of the AIDS Risk Inventory, and of illicit opiate use, as indicated by the proportions of opiate negative test results during the active phase of the study and the follow-up (p<0.001). 83.3% in the MMT+BDRC group and 76.2% in the standard MMT group were still actively participating in MMT at 6 months. Manual-guided behavioral drug and HIV risk reduction counseling is feasible to deliver by the trained MMT nursing personnel and appears to be a promising approach for improving the efficacy of standard MMT services in China.

Abstract
Accumulation of mutations and single nucleotide polymorphisms (SNPs) in the displacement loop (D-loop) of mitochondrial DNA (mtDNA) might be associated with cancer risk and disease outcome. We investigated the prediction power of D-loop SNPs in hepatocellular carcinoma (HCC) patients. No mutation in these HCC patients has prediction power for post-operational survival, whereas two SNP sites (nucleotides 146 T/C and 150 C/T) were identified by the log-rank test for statistically significant prediction of HCC survival. In an overall multivariate analysis, allele 146 was identified as an independent predictor of HCC outcome. The length of survival of patients with allele 146C was significantly shorter than that of patients with allele 146T (relative risk, 2.781; 95% CI, 1.127-6.859; p=0.026). The analysis of genetic polymorphisms in the mitochondrial D-loop can help identify patient subgroups at high risk of a poor disease outcome.

Abstract
Background Hepatocellular carcinoma (HCC) is frequently preceded by hepatitis virus infection or alcohol abuse. Genetic backgrounds may increase susceptibility to HCC from these exposures. Methods Mitochondrial DNA (mtDNA) of peripheral blood, tumor, and/or adjacent non-tumor tissue from 49 hepatitis B virus-related and 11 alcohol-related HCC patients, and from 38 controls without HCC were examined for single nucleotide polymorphisms (SNPs) and mutations in the D-Loop region. Results Single nucleotide polymorphisms (SNPs) in the D-loop region of mt DNA were examined in HCC patients. Individual SNPs, namely the 16266C/T, 16293A/G, 16299A/G, 16303G/A, 242C/T, 368A/G, and 462C/T minor alleles, were associated with increased risk for alcohol- HCC, and the 523A/del was associated with increased risks of both HCC types. The mitochondrial haplotypes under the M haplogroup with a defining 489C polymorphism were detected in 27 (55.1%) of HBV-HCCand 8 (72.7%) of alcohol- HCC patients, and in 15 (39.5%) of controls. Frequencies of the 489T/152T, 489T/523A, and 489T/525C haplotypes were significantly reduced in HBV-HCC patients compared with controls. In contrast, the haplotypes of 489C with 152T, 249A, 309C, 523Del, or 525Del associated significantly with increase of alcohol-HCC risk. Mutations in the D-Loop region were detected in 5 adjacent non-tumor tissues and increased in cancer stage (21 of 49 HBV-HCC and 4 of 11 alcohol- HCC, p < 0.002). Conclusions In sum, mitochondrial haplotypes may differentially predispose patients to HBV-HCC and alcohol-HCC. Mutations of the mitochondrial D-Loop sequence may relate to HCC development.

Abstract
In the 25 years since drug abuse re-emerged in China in the 1980s, the National Institute of Drug Dependence (NIDD) has made many contributions to China's antidrug campaign. This present paper offers an account of the history, current status and future of drug dependence research at NIDD. NIDD was originally a research centre at Beijing Medical University, founded by the Chinese Ministry of Health to address the rapid spread of drug abuse in China. Originally, the main task of NIDD was to complete the commissions assigned by the government and university. Further developments transformed NIDD into a national research institute in the field of drug addiction that began to conduct its own research. NIDD has now created a professional team spread across several independent departments involved in neurobiological mechanisms, epidemiological surveys and monitoring, pre-clinical and clinical evaluation of new drugs (mainly analgesic drugs and detoxification drugs) and informatics and data analysis. As a university-based research institute, NIDD's funding derives mainly from grants provided by the government and financial support from international organizations. Its past and present research has a gained NIDD a reputation with both practitioners and policy makers in the field of drug addiction. In the future, NIDD will continue to engage in various aspects of drug addiction research and will enter the field of brain function.

Abstract
OBJECTIVE The authors examined the prevalence and distribution of mental disorders in rural Chinese 15-34 years of age who committed suicide. They hypothesized that mental illness is a risk factor for suicide in this population and that the prevalence of mental illness is lower in females than in males. METHOD In this case-control psychological autopsy study, face-to-face interviews were conducted to collect information from proxy informants for 392 suicide victims and 416 living comparison subjects. Five categories of DSM-IV mental disorders (mood disorders, schizophrenia and other psychotic disorders, substance use disorders, anxiety disorders, and other axis I disorders) at the time of death or interview were assessed using the Chinese version of the Structured Clinical Interview for DSM-IV. Sociodemographic variables, social support, and life events were also assessed. RESULTS The prevalence of current mental illness was 48.0% for suicide victims and 3.8% for comparison subjects. Among suicide victims, mental illness was more prevalent in males than in females (55.1% compared with 39.3%). A strong association between mental illness and suicide was observed after adjustment for sociodemographic characteristics. Other risk factors included having a lower education level, not being currently married, having a lower level of social support, and having a history of recent and long-term life events. Additive interactions were observed between mental illness and lower level of social support. CONCLUSIONS Although mental illness is a strong risk factor for suicide, it is less prevalent among rural Chinese young people who committed suicide, particularly females, in comparison with other populations in China and in the West.

Abstract
Illicit drug use has become popular in China. Acknowledging the challenge of illicit drug use, China has adopted several new policies on the management of illicit drug use in recent years. This study reviews the current policies on drug use and assesses the harm reduction interventions among drug users in China. The review documents that the new policies on drug use provide a variety of choices of detoxification treatment for drug users. The methadone maintenance treatment and needle exchange programs have been adopted as harm reduction models in China. Most of the reviewed harm reduction programs have been successfully implemented and yielded positive effects in reducing drug related risk behaviors among drug users. Although there remain barriers to the effective implementation of policies on drug use and harm reduction programs, Chinese government has shown their commitment to support the expansion of harm reduction interventions for drug users throughout the country.

Looking for a solution for drug addiction in China: exploring the challenges and opportunities in the way of China's new Drug Control Law. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2009; 21:149-54. [PMID: 19896818 DOI: 10.1016/j.drugpo.2009.10.002] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2009] [Revised: 10/05/2009] [Accepted: 10/08/2009] [Indexed: 11/22/2022]
Abstract
In the wake of the deteriorating situation of drug addiction and related infectious diseases among injecting drug users (IDUs) in China in recent years, the Standing Committee of the National People's Congress of China adopted the new Drug Control Law which came into force in June 1, 2008. This law is part of a broad reform movement in China where drug addiction is no longer understood as simply a legal or moral issue but rather, as a complicated medical condition requiring comprehensive therapeutic strategies. Although the Drug Control Law draws a distinct line from previous Drug Control regulations in the country, there have still been dilemmas along the implementation process. This paper is intended to elaborate on the general principles of China's latest Drug Control Law from the point of view of scholars who are involved in the field of drug addiction research and treatment in China. This paper will also discuss the challenges we are currently facing, based on the observations and practical experiences the authors have obtained in China. It is hoped that by addressing these issues, we will be able to implement the new Drug Control Law more successfully and ensure that we deal more effectively with drug addiction in China.

Abstract
The harm associated with high-risk injected opiate use and the threat of the HIV epidemic among injecting drug users has become a worldwide problem. Twenty years ago, in the face of a rapid increase in mortality rates among injecting drug users and the upcoming threat of HIV, the first harm-reduction programs were implemented in the Western world. This paper is a literature review describing four forms of harm reduction currently in use in Europe, North America, and Australia. Each represents a reasonable counterapproach to the threat of increased prevalence of HIV among injecting drug users in transitional and developing countries. The paper attempts to explain the concepts behind the most commonly used types of harm reduction and provides a brief overview of the advantages and disadvantages of each and the reasons for their implementation. The main focus of the review is on the definition and the practical aspects of harm reduction; it includes a brief introduction of Chinese harm-reduction efforts and their implications.
