  • The carotid sinus nerve (CSN) is well known as mediating baroreflexes. However, studies of its detailed histological analysis are scant in the literature. Therefore, the current anatomical study sought to better elucidate the microanatomy of the CSN. Ten fresh frozen adult cadavers underwent dissection of the CSN. Then, it was harvested and submitted for histological and immunohistochemical staining. Specimens were all shown to be nerve fibers on histology and immunohistochemistry. We identified tyrosine hydroxylase positive fibers in all CSN specimens. These fibers were always found to be within the CSN and not on its surface i.e., epineurium. Based on our findings, the majority of fibers contained in the CSN are tyrosine positive in nature. Further studies are necessary to understand the true function of this autonomic nerve fibers.

  • Objectives: To analyze whether a concept similar to Korean 'Hwabyung' exists in China. We investigated the status of clinical studies conducted in China for relevant diseases and trends of the traditional Chinese medicinal (TCM) treatment adopted in clinical studies. Methods: To explore the concept of a condition similar to Korean Hwabyung in China, we searched for the existence of concept and pattern that were parallel or similar to those of Hwabyung in TCM text-books and diagnostic guidelines. We searched and analyzed clinical studies of TCM treatment for depression syndrome similar to Hwabyung from CNKI using terms 'depression' and 'qi stagnation transforming into fire'. Using extracted data, characteristics of clinical research, herbal medicine, and acupuncture treatment used in the clinical research and their effects were systematically reviewed. Results: Symptoms of 'qi stagnation transforming into fire' were most similar to those of Hwabyung. Nine articles were selected from a total 258 articles. Most of them used DSM-IV or CCMD-3 for depression diagnosis. They applied 'diagnostic and efficacy guidelines for TCM diseases and syndromes' for pattern diagnosis of 'qi stagnation transforming into fire'. Danzhixiaoyao-san and Jiaweixiaoyao-san were found to be effective when they were used alone or in combination with antidepressants. Acupuncture treatment also showed remarkable effect on LR3, HT7, LI4, PC6, GV20 when it was used alone or in combination with antidepressants. However, careful interpretation is required because a small number of studies are included.Conclusions: 'Qi stagnation transforming into fire' seemed to have symptoms similar to Hwabyung. However, further research is needed to determine its diseases and pattern types compared to Hwabyung. According to included studies of 'depression with Qi stagnation transforming into fire', herbal medicine and acupuncture treatment tended to be effective in relieving depressive symptoms. However, more discussion is required for future application of herbal medicine and acupuncture for treating Hwabyung.

  • Purpose: This review aimed to integrate the results of studies related to job embeddedness of clinical nurses and suggest directions for future research. Methods: A search for relevant studies was conducted using six databases according to the predetermined index terms "nurse" and "job embeddedness." A total of 28 studies that met the inclusion criteria were selected and analyzed. Results: The definition of job embeddedness was consistent in the articles, but the terms, scope, and use of tools to determine job embeddedness were not. In addition, no article suggested a theoretical framework. In all the studies except one, the tool used to measure job embeddedness was one revised from Mitchell et al. (2001). In 15 articles, a negative correlation was found between job turnover and turnover intention. Job embeddedness was also found to be associated with nurses' work environment, organizational citizenship behavior, and organizational commitment, and it had a positive impact on these variables. Conclusion: Job embeddedness can be used as a major variable to explain nurses's turnover intention. Job embeddedness is multidimensional, and a theoretical framework is needed to explain the job embeddedness of clinical nurses. Tools specific to Korea should be developed to measure the job embeddedness of Korean clinical nurses.

  • Objectives: The purpose of this research is to investigate clinical studies of essential tremor in China. Methods: We investigated clinical studies of Traditional Chinese Medicine therapies in traditional Chinese medical journals for essential tremor through the China National Knowledge Infrastructure (CNKI) database. In total, 15 clinical articles were analyzed. This study examined the authors; published years; types of study; treatment methods for the treatment and control groups; periods; outcome assessment; and results. Results: Nine articles used acupuncture, 6 articles used herbal therapy. The most commonly used acupoints were GV20, GB20, LR3, LI4, GB34, SP6, and EX-HN1. The most commonly used herbs were Paeoniae Radix Alba, Angelicae Gigantis Radix, Cnidii Rhizoma, Gastrodiae Rhizome and Uncariae Ramulus et Uncus. Total effective rate was 66.67-96.7%; the treatment group values were significantly higher than the control group values in all papers. Tremor score, HAMD, curative effect of TCM syndrome, and incidence of adverse effects were significantly more affected in the treatment group than in the control group. Conclusion: More active clinical studies are needed on essential tremor, and the results of this study can be used as a basis for future research.

  • Objectives: The purpose of this systematic review was to investigate the clinical effects of neurofeedback training on reducing anxiety. Methods: Eight databases were used to extract clinical reports on neurofeedback intervention for anxiety reduction published until 2016. We analyzed the characteristics of selected studies and evaluated biases using the Risk of Bias (RoB) assessment. Results: A total of 22 clinical trials were extracted for the analysis. The risk of bias in most studies was high or unclear. The Chinese Classification of Mental Disorders-3 (CCMD-3) was the most frequently used diagnostic criteria, the Hamilton Rating Scale for Anxiety (HAMA) was the most frequently used assessment tool, and the alpha wave activity increase, sensorimotor rhythm (SMR), and theta wave training were the most frequently used intervention methods. All papers showed a statistically significant decrease of anxiety symptoms; however, significant adverse events were not reported. Conclusions: Neurofeedback intervention might be beneficial for reducing anxiety. However, the quality of the studies used in the analysis was low, and the heterogeneity of the population and interventions was revealed. Therefore, more scientifically designed clinical studies regarding neurofeedback training are required.

  • Electrodiagnostic studies such as nerve conduction studies (NCS) and needle electromyography (EMG) provide important and complementary information for evaluating patients with suspected neuromuscular disorders. NCS and needle EMG are reasonably safe diagnostic investigations and are generally associated with only mild transient discomfort when performed by experienced physicians. However, there is the risk of complications in some patients, because NCS involve the administration of electric current and EMG involves inserting a needle percutaneously into muscle tissue. This article reviews the potential risks of NCS and needle EMG.

  • Objectives : The purpose of this study is to analyze the trends in foreign clinical trials for pediatric asthma in complementary and alternative medicine (CAM). Methods : We reviewed 31 randomized controlled trials (RCT) for pediatric asthma treatment in CAM published from 2005 to 2015 in PubMed and analyzed their treatments, compounds of herbal medicines, acupoints, methods of assessment, and treatment results. Results : The treatments used in the studies were herbal medicines, acupuncture, acupoint application, breathing training, supplement, normocaloric diet, yoga, massage therapy, and art therapy. The frequently used herbs were Asari Herba Cum Radix (細辛). Ephedrae Herba (麻黃), Astragali Radix. The most common acupoints were Feishu (肺兪, BL13). The methods of assessment in pediatric asthma were symptom scale, questionnaire of Quality of Life, lung function test, laboratory studies, and medication usage. In 28 out of 31 studies, treatment group gets better than non-treated group. Conclusions : This study shows that CAM is effective in treating pediatric asthma. More clinical studies using objective outcome measures are needed to prove its efficacy clearly.

  • Purpose: To understand the recent trend of studies for nursing job stress, we collected Korean articles about job stress of clinical nurses. Method: Seventy two articles were selected from the database of "richis", Korean journals of related academic society, and dissertation papers, which are presented from 1981 to 2002. Result: The trend shows that the number of researches for the job stress of clinical nurses are increasing from the year of 1996. Most of the researches are for dissertation papers (75.0%), have done surveys (90.3%), and used questionnaires (94.4%). The nurses who were studied have their jobs in general wards of hospitals (50.6%). And 36.1% of the researches used the tool of Kim and Gu (1984) to measure job stress. These researches focused mainly on job satisfaction, burnout and coping successively. Conclusion: As only 6 out of 72 researches examined in this study have experimental design (8.3%), it can be said that more experimental studies are needed in this area. And we might also consider to use meta-analytic techniques for further studies, because these researches have used very similar tools for the same subject.
