OBJECTIVE: To analyze the available data on the anti-anger effects of herbal medicines (HMs) as well as their underlying mechanisms in rat models. METHODS: From 6 electronic databases [PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang, Oriental Medicine Advanced Searching Integrated System (OASIS), and Research Information Sharing Service (RISS)], relevant animal experiments were searched by using "anger," "rats," and "animal" as search keywords. The last search was conducted on November 22, 2019, and all experiments involving rat models of anger and treatment using HMs published until the date of the search were considered. RESULTS: A total of 24 studies with 16 kinds of HMs were included. Most studies have used the "tail irritating method" and "social isolation and resident intruder" method to establish anger models. According to the included studies, the therapeutic mechanisms of HMs for anger regulation and important herbs by their frequency and/or preclinical evidence mainly incladed regulation of hemorheology (Bupleuri Radix, Paeoniae Radix Alba, and Glycyrrhizae Radix), regulation of sex hormones (Bupleuri Radix, Cyperi Rhizoma, and Paeoniae Radix Alba), regulation of neurotransmitters (Cyperi Rhizoma), regulation of anger-related genes (Bupleuri Radix, Glycyrrhizae Radix, and Paeoniae Radix Alba), and other effects. Overall, Liver (Gan) qi-smoothing herbs including Bupleuri Radix and Cyperi Rhizoma were the most frequently used. CONCLUSIONS This review found the frequent methods to establish an anger model, and major mechanisms of anti-anger effects of HMs. Interestingly, some Liver qi-smoothing herbs have been frequently used to investigate the anti-anger effects of HM. These findings provide insight into the role and relevance of HMs in the field of anger management.

PURPOSE: This study examined the relationships between nurses' exercise behavior and their anger control using a cross-sectional descriptive design. METHODS: The participants were 290 nurses in South Korea, who completed a survey questionnaire on general characteristics, the stage of exercise behavior change, and anger emotion, evaluated using state anger and anger expression method. RESULTS: Those who engaged in regular exercise behavior exhibited lower levels of state anger and higher levels of anger control than those who did not. In the prediction model, a significant association of exercise behavior with anger control was found. The levels of anger control decreased as the age, education level, and work experiences of nurses decreased. Anger control scores were significantly higher than anger suppression scores and anger expression-out scores in the hospital nurses. CONCLUSION: Engaging in regular exercise may help nurses manage anger emotions better.

PURPOSE: The preceptorenewly graduated nurse (NGN) relationship is integral to the successful experience of clinical teaching and learning and new nurses' transition. However, interpersonal conflicts between them are common. Little is known whether their anger contributes to their level of job satisfaction and burnout. This study aimed to examine the effects of each nurse's anger on job satisfaction and burnout in preceptoreNGN dyads.METHODS: A cross-sectional, correlational survey design was used. This study involved 121 preceptor enewly graduate nurse dyads in two hospitals in South Korea. Nurses completed a questionnaire about demographics, the State-Trait Anger Expression Inventory-Korean version, a job satisfaction measure, and the Copenhagen Burnout Inventory. This study adopted the Actor-Partner Interdependence Model to handle dyadic data.RESULTS: Preceptor nurses reported higher frequencies of feeling anger than did new nurses and appear to have higher levels of trait anger, anger-out, and burnout. Both the preceptors' and NGNs' trait anger was positively associated with preceptors' burnout. Suppressing anger was closely related to the nurses' own job satisfaction and burnout. Preceptors with a higher level of anger-control had higher job satisfaction, and NGNs with a higher level of anger-control had less burnout.CONCLUSION: The results indicate that preceptors and new nurses appear to experience significant anger, which is closely associated with their job satisfaction and burnout during their preceptorship. Anger management training programs geared toward educating both preceptors and new nurses about appropriate anger expression in the workplace should be developed to retain valuable nurses.

Emotional information is critical for our social life, in which attentional bias is now a focus in the study on attention. However, the attentional bias processing mechanism of emotional faces still arouses huge controversy. Using similar experimental paradigms and stimuli, the published studies have yielded contradictory results. Some studies suggest that angry faces could automatically stimulate attention, that is, there is an anger superiority effect. On the contrary, lines of growing evidence support the existence of a happiness superiority effect, suggesting that the superiority effect is shown in happy faces rather than angry faces. In the present paper, the behavioral and neuroscience studies of anger and happiness superiority effects are combined. It is found that there are three major reasons for the debate over the two types of effects, which include the choice of stimulus materials, the difference of paradigm setting, and the different stages of emotional processing. By comparatively integrating the previous published results, we highlight that the future studies should further control the experimental materials and procedures, and investigate the processing mechanism of anger and happiness superiority effects by combining cognitive neurobiology means to resolve the disputes.

PURPOSE: The Iri station explosion that occurred in 1977 was a major social disaster in Korea, caused by a fire in a train equipped with explosives. The purpose of this study was to investigate the social disaster adaptation experiences of railroad workers. METHODS: This study was based on qualitative research using phenomenological methodology. Participants were six railroad workers who experienced the Iri station explosion. Data were collected through in-depth interviews with individual workers from March to June, 2018. The data analysis method was based on Colaizzi's approach. RESULTS: Experiences of railroad workers were categorized into 12 themes and the following 6 theme clusters: (1) Anxiety due to the extreme vibration and crash, (2) Terror regarding the horrible situation that one cannot face, (3) Anger about the cause of the explosion and a sense of relief about survival, (4) Confusion regarding different rumors, (5) Various efforts to return to daily life, and (6) Trauma that continues to exist. CONCLUSION: The findings of this study recommend that railroad organizations and managers should pay attention to enhance disaster preparedness and develop organizational disaster coping guidelines for members. The results of this study can help us to better understand the various aspects of the Iri station explosion of 1977.

OBJECTIVE: Posttraumatic embitterment disorder (PTED), a subgroup of an adjustment disorder, is a feeling with anger and helplessness. Hemodialysis may be a trigger event leading to PTED. We investigated the prevalence of PTED in patients with each categorized stages of chronic kidney disease (CKD) and the association between PTED and depression and functional impairment. METHODS: Patients were categorized into three groups according to the stages of CKD (stage I–II, III–IV, and V). CKD (I–II) group was defined as estimated glomerular filtration rate (eGFR) >60 ml/min/1.73 m², CKD (III–IV) group as eGFR <60 ml/min/1.73 m², and CKD (V) group as CKD stage V including patients ongoing hemodialysis. Patients were assessed for the prevalence of PTED, depression, and decreased quality of life by using the scale of PTED, Patient Health Questionnaire-9 (PHQ-9), and EuroQol Five Dimensional Questionnaires, Visual Analogue Scale (EQ-5D-VAS), respectively. RESULTS: A total of 445 patients were analyzed. The number of patients in CKD (I–II) was 166, CKD (III–IV) was 172, and CKD (V) was 107. Multivariate analysis by binomial logistic regression demonstrated that CKD (V) was significantly associated with the prevalence of PTED (odds ratio, 4.13; 95% confidence interval, 1.56–15.6; p=0.006) after adjustment for age, gender, and diabetes mellitus. Also, a significant correlation existed between PTED and EQ-5D-VAS in all stages, but the correlation was nonsignificant between PTED and PHQ-9 score in group CKD (V). CONCLUSION: The findings suggest that PTED is underdiagnosed in CKD patients. Acknowledgment and diagnosis of PTED in CKD patients may lead to a better quality of life.

OBJECTIVE: A recently introduced single-photon emission computed tomography (SPECT), based on cadmium-zinc-telluride (CZT) detectors (D-SPECT), supports high energy resolution for cardiac imaging. Importantly, the high energy resolution may allow simultaneous dual-isotope (SDI) imaging (e.g., using Tc-99m and I-123). We quantitatively evaluated Tc-99m/I-123 SDI imaging by D-SPECT in comparison with conventional T1-201/I-123.MATERIALS AND METHODS: Energy resolution was measured as a percentage of the full width at half maximum(FWHM) for Tc-99m, I-123, and Tl-201. The impact of cross-talk and reconstructed image contrast were quantified by measuring the contrast-to-noise ratio (CNR), and the transmural defect contrast in the left ventricle wall (CTD) induced by a difference in energy, for combinations of Tc-99m/I-123 or Tl-201/I-123, using an RH-2 cardiac phantom. Corresponding measurement was also carried out in Anger SPECT (A-SPECT).RESULTS: The energy resolution of the D-SPECTsystem was 5.4%/5.1%for Tc-99m/I-123 and 5.4%/5.3%for Tl-201/I-123, which was approximately two times higher than the A-SPECT. No notable difference was confirmed in the CNRs of the two systems, but T1-201/I-123 showed overall higher value than Tc-99m/I-123. Compared to A-SPECT, CTD of D-SPECT significantly increased with both Tc-99m/I-123 and T1-201/I-123 (p < 0.05). In DSPECT, the combination of Tc-99m/I-123 had a slightly better CTD than T1-201/I-123. In addition, CTD of Tc-99m/I-123 was improved with scatter correction at both nuclides (p < 0.05), but in Tl-201/I-123, no significant improvement was confirmed in I-123 (p > 0.05).CONCLUSION: D-SPECT was considered to be capable of performing high-quality SDI imaging using Tc-99m/I-123.

OBJECTIVES: This study investigated the prevalence and psychosocial correlates of depressive symptoms in patients with hypertension.METHODS: The participants were 124 outpatients with hypertension who were treated at the Department of cardiology, Chosun University Hospital. Each subject was assessed concerning depressive symptom severity, state-trait anger, ego resilience, social conflict, and perceived stress using self-report questionnaires. A logistic regression model was constructed to examine the impact of psychosocial factors on depressive symptoms.RESULTS: A total of 37.1% of participants were identified as having depressive symptoms. Depressive symptoms were positively correlated with perceived stress, trait anger, social conflict, and state anger. On the other hand, ego resilience was negatively correlated with depressive symptoms. Further, perceived stress and state anger were related to a higher risk of depressive symptoms whereas ego resilience were associated with a lower risk of depressive symptoms.CONCLUSION: This study demonstrated a high prevalence of depressive symptoms in patients with hypertension. Moreover, several possible risk and protective psychosocial factors of depressive symptoms were determined. Especially, our findings suggest that improving ego resilience as well as lowering perceived stress and state anger would be important in the prevention and management of depression in patients with hypertension.

OBJECTIVE: Anger attacks have been observed in patients with obsessive-compulsive disorder (OCD), often triggered by obsessional triggers. However, few studies have reported the clinical characteristics and correlates of anger attacks among Chinese patients with OCD. METHODS: A total of 90 adults with a primary diagnosis of OCD, ranging from 15 to 78 years old, participated in the study. Participants were administered the Rage Outbursts and Anger Rating Scale (ROARS), Yale-Brown Obsessive-Compulsive Scale-Second Edition, and Brown Assessment of Beliefs Scale by a trained clinician. Patients completed the Obsessive-Compulsive Inventory-Revised and Depression Anxiety Stress Scale-21. RESULTS: A total of 31.3% of participants reported anger outbursts in the past week, and ROARS scores had no significant correlation with age, duration of illness, OCD severity, depression, or stress. However, ROARS scores were negatively related to education level, and positively related to obsessing symptoms and anxiety. CONCLUSIONS These data suggest that anger attacks are relatively common in Chinese patients with OCD. The severity of anger attacks is related to educational level, obsessing symptoms, and anxiety, which may be a latent variable reflecting executive functioning and emotion regulation skills.

BACKGROUND AND OBJECTIVES: Although Ling 6 sounds are often used in the rehabilitation process, its acoustic features have not been fully analyzed and represented in cortical responses. Current study was aimed to analyze acoustic features according to gender and emotional statuses of core vowels of Ling 6 sounds, /u/, /a/, and /i/. Cortical auditory evoked potentials (CAEPs) were also observed in those vowels. SUBJECTS AND METHODS: Vowel sounds /u/, /a/, and /i/ out of Ling 6 sounds representing low, middle and high frequencies were recorded from normal 20 young adults. The participants watched relevant videos for 4-5 minutes in order for them to sympathize emotions with anger (A), happiness (H), and sadness (S) before producing vowels. And without any emotional salience, neutrally production was performed. The recording was extracted for 500 ms to select pure vowel portion of production. For analysis of CAEP, the latencies and amplitudes of P1, N1, P2, N2, N1-P2 were analyzed. RESULTS: Intensities of /u/, /a/, and /i/ were 61.47, 63.38, and 60.55 dB. The intensities of neutral (N), H, A, S were 60.60, 65.43, 64.21, and 55.75 dB for vowel /u/, vowel /a/ were 61.80, 68.98, 66.50, and 56.23 dB, and vowel /i/ were 59.34, 64.90, 61.90, and 56.05 dB. The statistical significances for vowel and emotion were found but not for gender. The fundamental frequency (F0) of vowels for N, A, H, and S were 168.04, 174.93, 182.72, and 149.76 Hz and the first formant were 743.75, 815.59, 823.32, and 667.62 Hz. The statistical significance of F0 was found by vowel, emotion, and gender. The latencies and amplitudes of CAEP components did not show any statistical significance according to vowel. CONCLUSIONS: Ling 6 sounds should be produced consistently in the rehabilitation process for considering their difference of intensities and frequencies according to speaker’s emotions and gender. The vowels seemed to be interpreted as tonal stimuli for CAEP components of this study with similar acoustic features among them. Careful selection of materials is necessary to observe meaningful conclusion of CAEP measurement with vowel stimuli.
