OBJECTIVE:
To establish a model of long-term free drinking mouse by feeding mice with alcohol to simulate the state of human voluntary long-term drinking, and on this basis, to further discuss the evaluation criteria of long-term free drinking mice model in sports, anxiety and cognitive behavior.
METHODS:
Forty six-week-old SPF C57BL/6 male mouse were randomly divided into two groups: Long-term free drinking group (n=20) and normal control group (n=20). The two groups were given solid feed normally. The long-term free drinking group was free to take 10% alcohol and water every day, while the normal drinking group only took water every day. The mice were fed for 7 months, and were evaluated by a series of behavioral methods, including Rota-rod test, balance beam test, open filed test, the elevated plus maze, two-box social behavior, new object recognition, Y maze and water maze.
RESULTS:
With the increase of drinking days, the mice showed significant alcohol addiction in the alcohol preference test. With the increase of alcohol intake, the mice in the long-term free choice drinking group had slightly shiny fur and reduced diet. Compared with the control group, the weight gain began to slow down from the third month, and the weight decreased significantly by the sixth and seventh months (P=0.006, P < 0.001). The mice showed reduced balance locomotion ability (P=0.003, P=0.001) in the rotary bar and balance beam test. In the open field and elevated cross test, the mice had obvious anxiety-like behavior (P < 0.001). The mice showed decreased social ability in the two boxes of social behavior (P < 0.016). In the experiment of new object recognition and Y maze, the exploration of new object decreased (P=0.018, P=0.040). In the water maze, cognitive functions, such as learning and spatial memory were reduced (P < 0.001).
CONCLUSION
The successful establishment of the long-term free drinking mouse model is more convenient for us to carry out further research on the neural mechanism of alcohol addiction, and lays an experimental foundation for exploring the neural mechanism of alcohol addiction and related new targets.

A series of chemotherapeutic drugs that induce DNA damage, such as cisplatin (DDP), are standard clinical treatments for ovarian cancer, testicular cancer, and other diseases that lack effective targeted drug therapy. Drug resistance is one of the main factors limiting their application. Sensitizers can overcome the drug resistance of tumor cells, thereby enhancing the antitumor activity of chemotherapeutic drugs. In this study, we aimed to identify marketable drugs that could be potential chemotherapy sensitizers and explore the underlying mechanisms. We found that the alcohol withdrawal drug disulfiram (DSF) could significantly enhance the antitumor activity of DDP. JC-1 staining, propidium iodide (PI) staining, and western blotting confirmed that the combination of DSF and DDP could enhance the apoptosis of tumor cells. Subsequent RNA sequencing combined with Gene Set Enrichment Analysis (GSEA) pathway enrichment analysis and cell biology studies such as immunofluorescence suggested an underlying mechanism: DSF makes cells more vulnerable to DNA damage by inhibiting the Fanconi anemia (FA) repair pathway, exerting a sensitizing effect to DNA damaging agents including platinum chemotherapy drugs. Thus, our study illustrated the potential mechanism of action of DSF in enhancing the antitumor effect of DDP. This might provide an effective and safe solution for combating DDP resistance in clinical treatment.

OBJECTIVE:
To explore the risk factors of acute respiratory distress syndrome (ARDS) in patients with sepsis and to construct a risk nomogram model.
METHODS:
The clinical data of 234 sepsis patients admitted to the intensive care unit (ICU) of Tianjin Hospital from January 2019 to May 2022 were retrospectively analyzed. The patients were divided into non-ARDS group (156 cases) and ARDS group (78 cases) according to the presence or absence of ARDS. The gender, age, hypertension, diabetes, coronary heart disease, smoking history, history of alcoholism, temperature, respiratory rate (RR), mean arterial pressure (MAP), pulmonary infection, white blood cell count (WBC), hemoglobin (Hb), platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), D-dimer, oxygenation index (PaO2/FiO2), lactic acid (Lac), procalcitonin (PCT), brain natriuretic peptide (BNP), albumin (ALB), blood urea nitrogen (BUN), serum creatinine (SCr), acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA) were compared between the two groups. Univariate and multivariate Logistic regression were used to analyze the risk factors of sepsis related ARDS. Based on the screened independent risk factors, a nomogram prediction model was constructed, and Bootstrap method was used for internal verification. The receiver operator characteristic curve (ROC curve) was drawn, and the area under the ROC curve (AUC) was calculated to verify the prediction and accuracy of the model.
RESULTS:
There were no significant differences in gender, age, hypertension, diabetes, coronary heart disease, smoking history, alcoholism history, temperature, WBC, Hb, PLT, PT, APTT, FIB, PCT, BNP and SCr between the two groups. There were significant differences in RR, MAP, pulmonary infection, D-dimer, PaO2/FiO2, Lac, ALB, BUN, APACHE II score and SOFA score (all P < 0.05). Multivariate Logistic regression analysis showed that increased RR, low MAP, pulmonary infection, high Lac and high APACHE II score were independent risk factors for sepsis related ARDS [RR: odds ratio (OR) = 1.167, 95% confidence interval (95%CI) was 1.019-1.336; MAP: OR = 0.962, 95%CI was 0.932-0.994; pulmonary infection: OR = 0.428, 95%CI was 0.189-0.966; Lac: OR = 1.684, 95%CI was 1.036-2.735; APACHE II score: OR = 1.577, 95%CI was 1.202-2.067; all P < 0.05]. Based on the above independent risk factors, a risk nomograph model was established to predict sepsis related ARDS (accuracy was 81.62%, sensitivity was 66.67%, specificity was 89.10%). The predicted values were basically consistent with the measured values, and the AUC was 0.866 (95%CI was 0.819-0.914).
CONCLUSIONS
Increased RR, low MAP, pulmonary infection, high Lac and high APACHE II score are independent risk factors for sepsis related ARDS. Establishment of a risk nomograph model based on these factors may guide to predict the risk of ARDS in sepsis patients.

Journal of Forensic Medicine 2022;38(2):239-245
OBJECTIVES:
To investigate the epidemiological characteristics of antisocial personality disorder (ASPD) in young men in Chengdu and explore the characteristics and risks of violence.
METHODS:
Stratified random sampling was used to conduct a self-assessment questionnaire survey in 4 108 males aged from 18 to 34 in Chengdu, including general demographic characteristics, structured clinical interview for the diagnostic and statistical manual of mental disorders-Ⅳ axis Ⅱ disorders (SCID-Ⅱ) personality disorder screen questionnaire, violence questionnaire, psychosis screening questionnaire (PSQ), Alcohol Use Disorders Identification Test (AUDIT) and drug use. χ2 test, univariate and multivariate logistic regression were used for analysis and odds ratio (OR) was calculated.
RESULTS:
The positive rate of ASPD was 5.91%, which was associated with young age, unmarried, unemployment state, low educational level, violent behavior, psychotic symptoms, alcohol and drug use (P<0.05). Young men with ASPD also had a risk (P<0.05) of violence (OR was 8.51), multiple violence (OR was 16.57), injury (OR was 6.68), intentional violence (OR was 11.41), etc., the risk decreased after controlling for psychotic symptoms and substance abuse, but was still statistically significant.
CONCLUSIONS
The risk of violence, severe violence and intentional violence in young men in Chengdu is high, and psychotic symptoms and substance abuse increase the risk of ASPD violence and relate characteristics.

The purpose of this study was to investigate the effects of α2 adrenergic receptor agonist dexmedetomidine on withdrawal symptoms in alcohol-dependent rats and the underlying mechanism, so as to provide a scientific basis for the treatment of alcohol withdrawal syndrome (AWS). Adult Sprague-Dawley (SD) male rats were orally administered with 6% aqueous alcohol continuously for 28 d to establish alcohol drinking model, and then stopped drinking to induce AWS. Enzyme-linked immunosorbent assay (ELISA) was used to determine the content of norepinephrine (NE) in the locus coeruleus and hippocampus of rats. Dexmedetomidine (5, 10, and 20 μg/kg) was intraperitoneally injected respectively when the rats showed significant AWS. In some rats, α2 adrenergic receptor antagonist yohimbine was injected into hippocampus in advance. The results showed that, compared with the control group, the 6 h withdrawal group exhibited significantly increased AWS score and amount of repeat drinking. The NE contents in hippocampus and locus coeruleus of the last drinking and the 6 h withdrawal groups were significantly increased compared with those of the control group. Dexmedetomidine intervention significantly decreased AWS score and hippocampus NE content in the 6 h withdrawal group, while yohimbine could reverse these effects of dexmedetomidine. These results suggest that dexmedetomidine might improve the withdrawal symptoms in alcohol-dependent rats via activating α2 adrenergic receptor.

INTRODUCTION:
Few studies have examined the changes in the prevalence of comorbidity of mental and physical disorders in recent years. The present study sought to examine whether the prevalence of comorbidity of mental and physical disorders in Singapore showed any changes between 2010 and 2016.
METHODS:
We extracted data from two repeated nationally representative cross-sectional surveys conducted among resident adults aged ≥ 18 years in Singapore. Significant changes were tested using pooled multinomial logistic regression analyses.
RESULTS:
The prevalence of comorbid mental and physical disorders increased significantly from 5.8% in 2010 to 6.7% in 2016. Among those with physical disorders, there were significant increases over time in the prevalence of comorbid generalised anxiety disorder (GAD) (0.1% vs. 0.4%) and obsessive-compulsive disorder (OCD) (1.4% vs. 3.9%) in diabetes mellitus, and alcohol dependence in cardiovascular disorders (0.1% vs. 1.3%). Among those with mental disorders, there were significant increases over time in the prevalence of comorbid diabetes mellitus in OCD (4.1% vs. 10.9%), cancer in major depressive disorder (0.4% vs. 2.4%), and cardiovascular disorders in GAD (0.4% vs. 6.7%) and alcohol dependence (0.9% vs. 11.8%). Significant changes in the overall prevalence of comorbid mental and physical disorders were also observed across age group, education and employment status.
CONCLUSION
The prevalence of comorbid mental and physical disorders increased significantly over time. This finding supports the need for more appropriate clinical management with better integration between mental health and general medical care professionals across all aspects of the healthcare system to treat this comorbidity in Singapore.

7.Are Wischnewski Spots Found Only in Hypothermia?
Korean Journal of Legal Medicine 2019;43(1):16-22
Wischnewski spots (WS) are multiple black spots observed in the gastric mucosa at autopsy that are considered a reliable and important feature of hypothermia. Nonetheless, the frequency of WS varies widely. WS were discovered in 20 cases out of 3,493 autopsies (0.57%) conducted between 2001 and 2017 in the Department of Forensic Medicine of the School of Medicine, Kyungpook National University in Korea. This study aimed to investigate the distribution and size of WS in these cases and analyze the respective causes of death. Nine cases that occurred in winter were the same as the nine cases with hypothermia as the cause of death or contributory cause. The post-mortem blood alcohol test was positive in eight cases, with acute or chronic alcoholism determined as the cause of death in two of these cases. There were two cases of acute poisoning by pesticides. Putrefaction was noted in six cases (30%). WS presented in various sizes ranging from pinpoint to more than 5 mm in diameter, and the number of WS varied from 5 to 100. WS distribution was diffuse in four cases (20%) and localized in 13 cases (65%). Microscopic examination showed brown to black pigmentation but no neutrophil infiltration or vital reactions in the WS. Thus, WS are associated with hypothermia and are considered post-mortem alterations with variable appearance, size, and distribution. Hypothermia is an exclusive diagnosis at autopsy that should result from a combined assessment of toxicological tests, circumstance of death, and autopsy findings.

8.An Integrative Literature Review of Resilience in Adult Children of Alcoholics: Focusing on Operational Definitions and Moderators
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2019;28(1):50-63
PURPOSE: The objective of this study was to explore operational definitions and moderators of the resilience of adult children of alcoholics (ACOA) and its associated variables. METHODS: This integrative review was conducted based on a literature review method suggested by Whittemore and Knafl. Databases including PubMed, CINAHL, PsycINFO, and RISS were searched using the combinations of search terms such as; ‘adult children of alcoholics,’ ‘parental alcoholism,’ ‘resilience,’ and ‘children of alcoholics.’ RESULTS: Seventeen studies were selected for this review. Findings of integrative reviews reported operational definitions for the resilience of ACOA and moderators. The operational definition of ACOA's resilience is: (1) having no behavioral and emotional problem, (2) meeting social and developmental expectancies, (3) having the ability to cope with adversity, (4) having high self-concept, and (5) having a meaningful relationship. In addition, the varying environmental moderators include family communication, qualities of caring environment, parental communication, parentification, and social support. Several moderators were identified as positive effect, self-esteem, alcohol-specific coping style, locus of control, spirituality, the image of God, and dyadic cohesion in marital communication. CONCLUSION: Our study findings emphasize comprehensive understanding of diverse definition of resilience and moderators in developing nursing interventions to promote resilience in ACOA.

9.Association of Basic Psychological Needs with Recovery Attitude in Inpatients with Alcohol Use Disorders based on the Self-Determination Theory
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2019;28(4):344-352
PURPOSE: The purpose of this study was to examine the impact of autonomy, competence, and relationship on the recovery attitude of inpatients with alcohol use disorder.METHODS: This descriptive correlational study was based on the basic psychological needs theory, which is a sub-theory of self-determination theory (SDT). Study participants were 158 inpatients with alcohol use disorder from four mental hospitals in two areas. Data were collected from self-report questionnaires administered in September and October 2019. Data were analyzed using the t-test, one-way ANOVA, Pearson's correlation coefficients, and the multiple linear regression with IBM SPSS 22.0.RESULTS: Recovery attitude showed a positive correlation with autonomy (r=.62, p < .001), competence (r=.40, p < .001), and relationship (r=.33, p < .001). The results of the regression indicate the autonomy and competence explained 39% of the recovery attitude (R2=.40, F=51.04, p < .001).CONCLUSION: The results suggest that autonomy and competence play integral roles in the recovery attitude of inpatients with alcohol use disorders. Thus, mental health practitioners should develop psychological need-based interventions to improve the autonomy, competence, and recovery attitude of inpatients' with alcohol use disorder.

Journal of Korean Academy of Psychiatric and Mental Health Nursing 2019;28(4):298-308
PURPOSE: The purpose of this mixed-method study was to identify the demand for mental health nursing education and work of nurses at a private psychiatric hospital.METHODS: The survey of demand for mental nursing education was conducted by including 231 nurses at a private psychiatric hospital from November to December, 2017. Qualitative research by two focus groups was conducted from October to November, 2018.RESULTS: The mean of mental health nursing education demands according to major category were the therapeutic environment (4.27±0.76), substancerelated and addictive disorders (4.18±0.68), therapeutic relationship and communication (4.17±0.64), respect for human (4.11±0.74), and neurocognitive disorders (4.07±0.74). The qualitative research participants’ demands for mental health nursing education were classified into five categories: ‘discrimination power’, ‘communication techniques’, ‘psychiatric drugs’, ‘coping method’, and ‘legal issues’.CONCLUSION: Nurses with less psychiatric careers have strong need to learn a therapeutic environment and alcoholism, and nurses with more experience in psychiatry have education of humanities. Nurses at private psychiatric hospitals have high demand for continous education of updated mental nursing to expand their extensive experience required for becoming more professional nurses in future.
