  • Pathological hypertrophy of the heart is closely associated with endoplasmic reticulum stress (ERS), leading to maladaptations such as myocardial fibrosis, induction of apoptosis, and cardiac dysfunctions. Salubrinal is a known selective inhibitor of protein phosphatase 1 (PP1) complex involving dephosphorylation of phospho-eukaryotic translation initiation factor 2 subunit $(p-eIF2)-{\alpha}$, the key signaling process in the ERS pathway. In this study, the effects of salubrinal were examined on cardiac hypertrophy using the mouse model of transverse aortic constriction (TAC) and cell model of neonatal rat ventricular myocytes (NRVMs). Treatment of TAC-induced mice with salubrinal ($0.5mg{\cdot}kg^{-1}{\cdot}day^{-1}$) alleviated cardiac hypertrophy and tissue fibrosis. Salubrinal also alleviated hypertrophic growth in endothelin 1 (ET1)-treated NRVMs. Therefore, the present results suggest that salubrinal may be a potentially efficacious drug for treating pathological cardiac remodeling.

  • Objectives : This study explores perspectives, reasons, functions of dreams in order to develop a treatment model. Methods : We searched CNKI, KISS, NDSL. Papers published since 2002, which are classified in categories. Results : 1. The Recognitions about the dream of Oriental Medicine is based on "Hwangjenaegyeong Eumsabalmong(黃帝內經 淫邪發夢)". 2. By each era, There are a variety of etiological causes, stages. 3. Dreams are generated by the internal stimuli Physiological activities of the Jangbu(臟腑),Deficiencies of yin and yang(陰陽), Pathological changes in the Jangbu(臟腑), Pathology products, external stimuli Yukeum(六淫), Eumsiksang(飮食傷), and unusual feelings. 4. Spirit(神) comes from brain(腦), not heart(心). So what we call brain spirit(腦神) is right. Dreams are the mental activity related to the brain. 5. Dreams are the reflection of the pathological changes of the human body. And it shows the development, changes and prognosis of disease. Dreams sometimes illustrate the incidence of the disease Conclusions : We organized perspectives, Causes and Functions of dreams mentioned in Oriental Medicine Literatures. Health is closely related to the dream. Therefore, we propose that the dream is worth for the diagnosis and treatment in oriental medicine.

  • Background: Flexible flat foot is that the medial longitudinal arch collapses in weight bearing and returns normal arch when weight is removed and the weight bearing shifts toward medial part of the foot, which can cause pathological problems in the alignment of the lower extremities and the entire body. Objective: To compare the foot pressure for adults with flexible flat foot. Design: Quasi-Experimental Study Methods: 24 participants with flexible flat foot were recruited and were randomly divided into Visual feedback Short Foot Exercise (VSFE) group and Short Foot Exercise (SFE) group. To compare changes of foot pressure about pre and post intervention, the contact pressure measurement was conducted. Results: In the VSFE, significant differences were observed for the foot pressure of the 1st toe, 1st, 3rd and 4-5th metatarsal, midfoot, medial and lateral heel (p<.05). The foot pressure of the 3rd and 4-5th metatarsal, midfoot showed significant differences in the SFE (p<.05). The contact pressure of the 1st toe, 3rd metatarsal showed significant differences between the groups. Conclusions: Visual feedback short foot exercise can be useful for moving the pressure from medial to lateral part, and can prevent possible pathological problems.

  • Background: Brain magnetic resonance imaging (MRI) is routinely performed to identify brain lesions in girls with central precocious puberty (CPP). We aimed to investigate the prevalence and type of brain lesions among Korean girls with CPP and evaluate the need for routine brain MRI examinations. Methods: This retrospective cross-sectional study evaluated data on 3,528 girls diagnosed with CPP from April 2003 to December 2016, and identified 317 girls who underwent sellar MRI. Exclusion criteria were patients with a known brain tumor or who did not undergo brain MRI due to refusal or the decision of the pediatric endocrinologist. Results: Normal sellar MRI findings were observed in 291 of the 317 girls (91.8%). Incidental findings were observed in 26 girls (8.2%). None of the patients had pathological brain lesions. Conclusion: The prevalence of intracranial lesions among girls who were generally healthy and without neurological symptoms but diagnosed with CPP was lower than that previously reported. Furthermore, none of the identified lesions required treatment. It may be prudent to reconsider the routine use of brain MRI to screen all patients with CPP, especially if they are healthy and neurologically asymptomatic, and are girls aged 6-8 years.

  • Objectives : The purpose of this paper is to understand the meaning of Yangmingzhongfeng in the Shanghanlun. Methods :Each verse was analyzed, along with consideration of the general context of the Bianyangmingbingmaizhengbingzhi(辨陽明病脈證幷治) chapter where Yangmingzhongfeng is explained. The meaning of Yangmingzhongfeng was discussed with a focus on the intention underlying the contrast between Zhongfeng[中風] and Zhonghan[中寒] within the text. Results : In Yangming Disease, disease patterns that have mutated from other channels are differentiated as either Zhuanshu[轉屬, change of assignment] or Zhuanxi[轉繫, change of connection]. Zhuanshu refers to the situation where symptoms of the original pathological site has disappeared, therefore being assigned to Yangming. Zhuanxi refers to the before-and-after pathological sites being connected. The condition of Zhuanxi is further divided into Taiyin and Yangming, where Zhuanxi Yangming needs to be differentiated from Zhuanshu Yangming in that the cathartic method[下法] cannot be applied even with the existence of constipation, despite it being the indication for such treatment. Yangming Zhongfeng and Yangming Zhonghan are differentiated according to coldness and heat of Zhuanxi Yangming. Conclusions : Yangming Zhongfeng refers to the heat type of Zhuanxi Yangming where the person presents constipation whilst residing exterior pattern. Yangming Disease cannot be understood as having a uniform pattern of Weijiashi-constipation-Shengqitang, and its disease pattern requires a multi-dimensional approach.

  • Tumoral calcinosis is a condition characterized by deposition of calcium salts in the skin and subcutaneous tissue, commonly found around the joints. However, tumoral calcinosis of the auricle is extremely rare. We present the case of a 13-year-old boy with tumoral calcinosis of the helix of the ear auricle. A 13-year-old boy presented with a 10-year history of an enlarging mass on the left auricle. The mass was hard, non-tender, and non-compressible. The patient had no history of trauma. Complete surgical excision and pathological examination of the specimen was performed. The final diagnosis of the excised mass was tumoral calcinosis. After 9 months of follow-up, there were no signs of recurrence of the tumor and the patient was satisfied with the surgical results. Tumoral calcinosis of the auricle is extremely rare and may be misdiagnosed as other tumors. Pathological examination is essential for definitive diagnosis and complete surgical excision should be considered as the treatment of choice.

  • Objectives: The purpose of this research is to investigate recent clinical studies of Intestinal Metaplasia (IM) based on a search of the China National Knowledge Infrastructure (CNKI). Methods: We investigated recent clinical studies of Oriental medicine therapies in traditional Chinese medical journals for IM through a CNKI search. 20 clinical articles published from 2010 to 2016 were analyzed. This study examined the authors, publication years, types of studies, criteria for diagnosis and evaluation, periods, purposes of study and articles classified by methods of treatment. Results: Most of articles were classified as randomized controlled trial. IM was diagnosed using gastroscopy, pathological examination and clinical symptoms in a high proportion of articles. The criteria for evaluation most frequently used were the effective ratios of clinical symptoms, gastroscopy and pathological tests. The methods of treatment in all studies were Chinese herb medicine. Acupuncture, acupoint injection therapy, and embedding therapy were also used in several studies. Conclusion: In this study, the Chinese treatment for IM was markedly effective. To improve the treatment of IM in Korea, many clinical studies and case reports are required, based on Chinese medicine.

  • Fibrofolliculoma is a benign tumor characterized by a smooth, dome-shaped papule of size 2-4 mm. Most fibrofolliculomas occur as multiple lesions, and very rarely, they are solitary. Herein, we report a case of solitary fibrofolliculoma found in the alar rim, without the typical characteristics of a fibrofolliculoma. A 42-year-old man visited the hospital with a protruding lesion that had occurred 1 year previously. A mass of size 5×7 mm was observed on the left alar rim. The tumor was dome-shaped and palpable. The patient did not have any similar lesions elsewhere. No family member was known to have such a lesion. An incisional biopsy was performed before surgery, and pathological examination revealed hyperkeratosis and dyskeratosis; however, an accurate diagnosis was not made. Complete resection was planned for the mass on the alar rim. The resected mass was subjected to permanent biopsy, and the pathological examination results led to the diagnosis of fibrofolliculoma. Therefore, when diagnosing a dome-shaped mass in the alar rim, despite the suspicion of a very rare disease, it is necessary to suspect fibrofolliculoma and consider the process from diagnostic examination to treatment.

  • Glial cells, including astrocytes and microglia, interact closely with neurons and modulate pain transmission, particularly under pathological conditions. In this study, we examined the excitability of substantia gelatinosa (SG) neurons of the spinal dorsal horn using a patch clamp recording to investigate the roles of microglial activation in the nociceptive processes of rats. We used xanthine/xanthine oxidase (X/XO), a generator of superoxide anion (O2·-), to induce a pathological pain condition. X/XO treatment induced an inward current and membrane depolarization. The inward current was significantly inhibited by minocycline, a microglial inhibitor, and fluorocitrate, an astrocyte inhibitor. To examine whether toll-like receptor 4 (TLR4) in microglia was involved in the inward current, we used lipopolysaccharide (LPS), a highly specific TLR4 agonist. The LPS induced inward current, which was decreased by pretreatment with Tak-242, a TLR4-specific inhibitor, and phenyl N-t-butylnitrone, a reactive oxygen species scavenger. The X/XO-induced inward current was also inhibited by pretreatment with Tak-242. These results indicate that the X/XO-induced inward current of SG neurons occurs through activation of TLR4 in microglial cells, suggesting that neuroglial cells modulate the nociceptive process through central sensitization.
