Korean government first proposed the internationalization of the Korean medicine strategy in 2003. During this time, the Ministry of Health and Welfare enacted a series of policies to support the internationalization of Korean medicine, which has led to fruitful results in attracting foreign patients, international education, and international research cooperation. At the same time, Korean medicinal materials, functional foods, and cosmetics have also entered overseas markets, reaping substantial economic benefits. As Chinese and Korean traditional medicines have the same origin and different flows, the experience of the international development of Korean medicine can provide a reference for the development of the internationalization of TCM to a certain extent.

Aim To discuss the mechanism of Lurong Dabu Decoction on cough variant asthma. Methods Guinea pigs were divided into normal group(CON), model group(OVA), Lurong Dabu Decoction high-dose group(HIGH),low-dose group(LOW), and dexamethasone group(DEX)at random. The CVA model was established by smoking plus injection of OVA, aluminum hydroxide solution and nebulized inhalation to stimulate cough. Gguinea pigs were dissected 24 hours after the last challenge to obtain alveolar lavage fluid(BALF)and lung tissues. Immunoadsorption(ELISA)method was applied to detect the types of inflammatory cells and the content of inflammatory cytokines in BALF; HE and Masson staining of the middle lobe of the left lung were used to observe the pathological changes in lung tissues; immunohistochemical staining was used to observe TLR4 and WNT-5A protein expression and distribution of lung tissues; the protein extracted from the upper lobe of the left lung was used to measure the level of TLR4 and WNT-5A protein in lung tissues by Western blot; immunofluorescence was employed to measure the fluorescence intensity of TLR4 and WNT-5A in lung tissues; flow cytometry was used to detect IL-4 and IFN-γ in guinea pig lung tissues. Results Lurong Dabu Decoction could improve guinea pig airway inflammation, inhibit collagen fiber deposition, reduce the content of IL-4, IL-5, and IL-13 in BALF, and inhibit the protein expression of TLR4 and WNT-5A in lung tissues and increase IFN-γ levels in lung tissues while decreasing IL-4 levels. Conclusion Lurong Dabu Decoction may inhibit the occurrence of CVA through TLR4/WNT-5A signaling pathway.

SUMMARY: The aim of this study was to determine the morphologic characteristics of the lingual foramen and lateral lingual foramen using cone-beam CT in elderly Korean. Cone-beam CT images were obtained from 80 Korean older than 50 years (mean age, 65.2 years). The prevalence of the lingual and lateral lingual foramina at the lingual aspect of the mandible was determined. The diameter and height to the upper margin of the foramina from the mandibular inferior margin, and the bone height to the alveolar crest from the mandibular inferior margin were measured. In addition, the location of the lateral lingual foramen, the direction of its canal, and the presence of communication with the mandibular canal were evaluated. All of elderly Korean possessed at least one lingual foramen, with two or three foramina occurring in 77.5 % of Korean. A lateral lingual foramen was observed in 91.3 % of Korean, with the prevalence being highest at the second premolar in dentulous cases (21.6 %; 33/153). The very high frequencies of these foramina were attributable to high frequencies of relatively small-diameter inferior lingual foramen and lateral lingual foramen in the incisor region. The prevalence of a large-diameter (≥1 mm) superior lingual foramen was high, at 31.0 %. A large-diameter lateral lingual foramen in the premolar region occurred at a frequency of 17.0 %; communication with the mandibular canal was observed in 70.0 % of these cases. These quantitative data on the lingual and lateral lingual foramina of the mandible provide valuable information that could help to avoid surgical complications during implant placement in elderly Korean.
RESUMEN: El objetivo de este estudio fue determinar las características morfológicas del foramen lingual y del foramen lingual lateral mediante TC de haz cónico en adultos mayores coreanos. Se obtuvieron imágenes de TC de haz cónico de 80 coreanos mayores de 50 años (edad media, 65,2 años). Se determinó la prevalencia de los forámenes linguales y linguales laterales en la cara lingual de la mandíbula. Se midió el diámetro y la altura hasta el margen superior de los forámenes desde el margen inferior mandibular, y la altura ósea hasta la cresta alveolar desde el margen inferior mandibular. Además, se evaluó la ubicación del foramen lingual lateral, la dirección de su canal y la presencia de comunicación con el canal mandibular. Todos los adultos mayores coreanos tenían al menos un foramen lingual, con dos o tres forámenes en el 77,5 %. Se observó un foramen lingual lateral en el 91,3 %, siendo la prevalencia más alta en el segundo premolar en casos dentados (21,6 %; 33/ 153). Las mayores frecuencias de estos forámenes se atribuyeron a altas frecuencias de foramen lingual inferior y foramen lingual lateral de diámetro relativamente pequeño en la región de los incisivos. La prevalencia de un foramen lingual superior de gran diámetro (≥1 mm) fue alta, del 31,0 %. Un foramen lingual lateral de gran diámetro en la región premolar ocurrió con una frecuencia del 17,0 %; se observó comunicación con el canal mandibular en el 70,0 % de estos casos. Estos datos cuantitativos sobre los forámenes linguales y linguales laterales de la mandíbula proporcionan información valiosa que podría ayudar a evitar complicaciones quirúrgicas durante la colocación de implantes en adultos mayores coreanos.

BACKGROUND@#Nonalcoholic fatty liver disease (NAFLD) is becoming a global health problem. Bisphenol A (BPA), one of most widely used environmental chemicals, is suspected to be a contributor to the development NAFLD. This study was performed to examine the relationship between human BPA levels and risk of NAFLD.@*METHODS@#The data (n = 3476 adults: 1474 men and 2002 women) used in this study were obtained from the Korean National Environmental Health Survey III (2015-2017). BPA levels were measured in urine samples. NAFLD was defined using hepatic steatosis index after exclusion of other causes of hepatic diseases.@*RESULTS@#There was a significant linear relationship between the elevated urinary BPA concentrations and risk of NAFLD. In a univariate analysis, odds ratio (OR) of the highest quartile of urinary BPA level was 1.47 [95% confidence interval (CI) 1.11-1.94] compared to the lowest quartile. After adjusted with covariates, the ORs for NAFLD in the third and fourth quartiles were 1.31 [95% CI 1.03-1.67] and 1.32 [95% CI 1.03-1.70], respectively.@*CONCLUSIONS@#Urinary BPA levels are positively associated with the risk of NAFLD in adults. Further experimental studies are needed to understand the molecular mechanisms of BPA on NAFLD prevalence.

SUMMARY: Metopic suture can be visualized from the nasion to the bregma along the arch of the frontal bone in mid-sagittal plane. Persistent metopic suture normally closing between 1st and 2nd year of life has also been related with ethnicity. The present study reports the presence of complete and incomplete metopic sutures in Nepalese and Korean population skulls which helps to shed light on its incidence rate. Out of 121 adult skulls in Nepalese population, metopic suture was found to be present in 33 skulls. Incomplete metopic sutures showed variations of morphology, like linear (6.61 %), V-shaped (8.26 %) and double incomplete (10.74 %) and two cases with complete metopic suture, which showed variation in interdigitation between its anterior and posterior ends. Korean population showed metopic suture to be present in 8 skulls out of 104 with metopism in 3 skulls. Incomplete metopic sutures like double incomplete (1.92 %) and linear (2.88 %) were also noted. Alterations to local strains could be the contributing factor for such variation and complexity of interdigitation, which occur during the growth of the braincase. The knowledge of the metopic suture and its variations according to ethnicity is important and should be considered to prevent wrong diagnosis. The presence of different types of metopic sutures as reported by the present study provides informative value on the presence and variation of such sutures in population depending on ethnicity and ought to be helpful in diagnostic sequences in emergency setting.
RESUMEN: La sutura metópica se puede visualizar desde nasión hasta el bregma a lo largo del arco del hueso frontal en el plano mediano sagital. La sutura metópica persistente que normalmente se cierra entre el primer y segundo año de vida, también se ha relacionado con el origen étnico. El presente estudio informa la presencia de suturas metópicas completas e incompletas en los cráneos de la población nepalesa y coreana, lo que además de entregar información sobre su tasa de incidencia. De 121 cráneos adultos en la población nepalesa, en 33 de ellos se encontró la sutura metópica. Las suturas metópicas incompletas mostraron variaciones de la morfología, como lineal (6,61 %), en forma de V (8,26 %) y doble incompleta (10,74 %), además de dos casos con sutura metópica completa, que mostraron variación en la interdigitación entre sus extremos anterior y posterior. De los 104 cráneos de la población coreana en 8 se presentó la sutura metópica y en 3 metopismo. También se observaron suturas metópicas incompletas como doble incompleta (1,92 %) y lineal (2,88 %). Las alteraciones en las etnias locales podrían ser el factor contribuyente para tal variación y complejidad de la interdigitación, que ocurre durante el crecimiento de la cráneo. El conocimiento de la sutura metópica y sus variaciones según el origen étnico es importante y debe considerarse para prevenir un diagnóstico incorrecto. La presencia de diferentes tipos de suturas metópicas según lo informado en el estudio, proporciona un valor informativo sobre la presencia y la variación de tales suturas en la población, dependiendo de la etnia, y debería ser útil en las secuencias de diagnóstico en situaciones de emergencia.

Purpose: We performed this study to determine the association between serum 25-hydroxyvitamin D [25(OH) D] level and myopia in adults. Methods: A total of 25,199 subjects aged ?20 years were included from the National Health and Nutrition Examination Survey 2008�12. Blood 25(OH)D levels were evaluated from blood samples. Refractive error was measured without cycloplegia. Myopia and high myopia were defined as ?-0.50 diopters (D) and ?-6.0 D, respectively. Other covariates such as education, physical activity, and economic status were obtained from interviews. Results: Linear regression analysis showed that as 25(OH) D level increased by 1 ng/mL, myopic refractive error significantly decreased by 0.01 D (P < 0.001) after adjusting for potential confounders including sex, age, height, education level, economic status, physical activity, and sunlight exposure time. The odds ratios for myopia was 0.75 (95% Confidence interval [CI]; 0.67�84, P < 0.001) in the highest 25(OH) D quintile compared to the lowest quintile. The odds ratios for high myopia was 0.63 (95% CI; 0.47�85, P < 0.001) in the highest 25(OH)D quintile compared to the lowest quintile. Conclusion: Serum 25(OH)D level was inversely associated with myopia in Korean adults

PURPOSE: We determined whether elevated serum alkaline phosphatase (ALP) was related to prevalence, location, type, length, and recurrence of pterygium in a population from the Republic of Korea.METHODS: A nationwide cross-sectional dataset, the Korean National Health and Nutrition Examination Survey (2008–2011), was used in this study. All participants were > 30 years of age and underwent the ALP test and ophthalmic evaluation (n = 22,359). One-way analysis of variance, the chi-square test, and Fisher's exact test were used to compare characteristics and outcomes among participants. Multivariable logistic regression was used to examine the possible associations between serum ALP levels and various types of pterygium. Data were adjusted for known risk factors for development of pterygium and ALP elevation (age, sex, residence, sunlight exposure, drinking, smoking, hypertension, diabetes, BMI, AST, ALT, vitamin D, and HDL).RESULTS: The overall prevalence of pterygium was 8.1%, and participants with pterygium had higher levels of serum ALP (p < 0.001). Participants with higher serum ALP had a significantly higher prevalence of all types of pterygium than those in the lower serum ALP quartiles. After adjusting for potential confounding factors, multivariate logistic regression analysis revealed that ALP was associated with the prevalence of pterygium (odds ratio [OR], 1.001; p = 0.038). Trend analysis between the OR and ALP quartiles revealed a linear trend in overall prevalence and in the intermediate type of pterygium. Subgroup analysis revealed a stronger correlation in participants > 50 years of age. One-way analysis of variance revealed an association between the size of pterygium and serum ALP quartile levels. Serum ALP was not associated with recurrence of pterygium.CONCLUSIONS: Increased serum ALP was associated with the prevalence and size of pterygium.

OBJECTIVES: This study examined the association of the total diet quality with the incidence risk of metabolic syndrome constituents and metabolic syndrome among Korean adults.METHODS: Based on a community-based cohort of the Korean Genome and Epidemiology Study (KoGES) from 2001 to 2014, data from a total of 5,549 subjects (2,805 men & 2,744 women) aged 40~69 years at the baseline with a total follow-up period of 38,166 person-years were analyzed. The criteria of the National Cholesterol Education Program Adult Treatment Panel was employed to define metabolic syndrome. The total diet quality was estimated using the Korean Healthy Eating Index (KHEI). Hazard ratios (HR) and 95% confidence intervals (CI) for risk of metabolic syndrome constituents and metabolic syndrome in relation to KHEI quintile groups was calculated by multivariate Cox proportional hazards regression model.RESULTS: After adjusting for age, energy intake, income, education, physical activity, smoking, and drinking, the incidence of abdominal obesity and high blood pressure was significantly lower, by approximately 29.7% (P < 0.01) and 25.2% (P < 0.01), respectively, in the fifth KHEI quintile compared to the first quintile in men. A significant decreasing trend of the metabolic syndrome incidence was observed across the improving levels of KHEI (HRq5vs.q1: 0.775, 95% CIq5vs.q1: 0.619~0.971, P for trend < 0.01). In women, the incidence of abdominal obesity and metabolic syndrome was significantly lower, by approximately 29.8% (P < 0.01) and 22.5% (P < 0.05), respectively, in the fifth KHEI quintile compared to the first quintile adjusting for multiple covariates. On the other hand, the linear trend of metabolic syndrome risk across the KHEI levels did not reach the significance level.CONCLUSIONS: A better diet quality can prevent future metabolic syndrome and its certain risk factors among Korean men and women.

BACKGROUND/OBJECTIVES: Hypertriglyceridemia may be a more important predictor of cardiovascular disease in Asian population consuming carbohydrate-rich foods than in Western populations. Dairy products are known to play a beneficial role in obesity, dyslipidemia, and metabolic syndrome, but the results vary depending on gender and obesity. In this study, we investigated the associations between dairy product intake and hypertriglyceridemia in Korean adults.SUBJECTS/METHODS: The participants were selected from the Korea National Health and Nutrition Examination Survey 2007–2012 (KNHANES IV and V). A total of 22,836 participants aged 19–64 years were included in the analysis. A food frequency questionnaire used to determine the frequency of consumption of products (milk and yogurt). Multivariable logistic regression was used to assess the associations between dairy product intake and hypertriglyceridemia.RESULTS: A significantly decreased risk of hypertriglyceridemia was detected in the highest dairy product intake frequency group (≥ 1 time/day) (odd ratio [OR] = 0.79; 95% confidence interval [CI] 0.64–0.97, P for trend = 0.022) compared to that for the lowest dairy product intake frequency group. Among obese participants, the group with the highest intakes of milk (in men, OR = 0.64; 95% CI: 0.46–0.91, P for trend = 0.036) and yogurt (in women; OR = 0.53; 95% CI: 0.29–0.94, P for trend = 0.019) showed inverse associations with hypertriglyceridemia. No associations were detected in normal weight participants.CONCLUSION: The association between dairy product intake and hypertriglyceridemia differed by gender and obesity status. Further prospective studies are needed to confirm these associations.

BACKGROUND: This study aimed to identify the relationship between exposure to bisphenol A (BPA) and seafood consumption using a nationally representative data of the general Korean population.METHODS: This study was conducted on 5,402 adults aged 19 years and older (2,488 men, 2,914 women) based on the second Korean National Environmental Health Survey (2012–2014). We stratified the data according to gender and analyzed urinary BPA concentrations in terms of sociodemographic characteristics, health behavior, dietary factor, and seafood consumption. In the high and low BPA exposure groups, the odds ratios (ORs) were calculated using logistic regression analysis according to the top 75th percentile concentration.RESULTS: In men, large fish and tuna and other seafood categories had significantly higher ORs before and after adjustment in the group who consumed seafood more than once a week than in the group who rarely consumed seafood, with an adjusted value of 1.97 (95% confidence interval [CI]: 1.12–3.48) and 1.74 (95% CI: 1.10–2.75), respectively. In the shellfish category, the unadjusted OR was 1.61 (95% CI: 1.00–2.59), which was significantly higher in the group who consumed seafood more than once a week than in the group who rarely consumed seafood. However, the OR after adjusting for the variables was not statistically significant. In women, the frequency of seafood consumption and the concentration of urinary BPA were not significantly associated.CONCLUSIONS: BPA concentration was higher in men who frequently consumed large fish and tuna, shellfish and other seafood in this study.

OBJECTIVE@#To explore the effect of pretreatment of neuroblastoma cells with hot water extract of Korean ginseng on MNNG-induced parthanatos and its mechanism.@*METHODS@#Neuroblastoma SH-SY5Y cells were pretreated with 1 mg/L hot water extract of Korean ginseng before induction with 250 μmol/L MNNG for 1 h or 4 h. CCK-8 and cell flow cytometry were used to detect cell survival rate. Western blotting was used to detect the changes in poly(ADP-ribose) (PAR) expression in the treated cells. Immunofluorescence assay was used to detect nuclear distribution of apoptosis-inducing factor (AIF), and flow cytometry was used to detect the level of reactive oxygen species (ROS) in the cells.@*RESULTS@#Compared with the blank control cells, MNNG-treated SH-SY5Y cells showed significantly decreased survival rate as the concentration of MNNG and the stimulation time increased ( < 0.05). Stimulation with MNNG also resulted in significantly increased expression of PAR protein in the cells ( < 0.05). Pretreatment of the cells with hot water extract of Korean ginseng obviously inhibited MNNG-induced cell death and significantly reduced AIF expression and nucleation in the cells ( < 0.05). MNNG stimulation significantly increased ROS level in the cells, which was decreased significantly by pretreatment of the cells with the extract ( < 0.05).@*CONCLUSIONS@#Pretreatment with hot water extract of Korean ginseng reduces MNNG-induced parthanatos and ROS production in SH-SY5Y cells.

La disección virtual es una herramienta educativa sumamente valiosa en anatomía. Es particularmente útil cuando hay escasez de cadáveres o en los casos en que la disección no sea posible por motivos religiosos o éticos. En este trabajo los autores presentan una reconstrucción 3D de un corazón masculino a partir de la información del proyecto Korean Visible Human, realizado en el marco de asociaciones de la cátedra de anatomía digital de la UNESCO creada recientemente en la Universidad Descartes. La segmentación manual de 1640 cortes anatómicos se logró a través del software Winsurf, produciendo un modelo vectorial 3D interactivo del corazón y la anatomía que lo rodea. Se reconstruyeron ochenta y cuatro estructuras, incluyendo el corazón y sus vasos (27 estructuras), tráquea, esófago, pulmones, cayado aórtico, vena cava inferior, riñones, sistema esquelético conformado por 58 estructuras, entre ellas: esternón, cartílagos costales, vértebras torácicas y discos intervertebrales, sacro, coxales y piel. El modelo vectorial 3D obtenido se exportó en formato PDF 3D produciendo una verdadera herramienta de disección virtual a través de la interfaz de Acrobat: las estructuras anatómicas pueden individualizarse y manipularse interactivamente como 84 objetos 3D separados. Además, se pueden agregar "etiquetas" con el nombre de cada elemento anatómico. Esta nueva mesa de disección virtual computarizada es una herramienta simple y poderosa tanto para alumnos como para docentes de anatomía. Además, resulta ser la base para futuras herramientas de simulación que contribuirán al entrenamiento de cirujanos
The virtual dissection is a remarkable learning tool in anatomy. It is particularly useful in the case of lack of cadavers or if anatomical dissection is impossible due to ethical or religious reasons. The authors present here a 3D reconstruction of the female's heart from the Visible Korean human data, made in the frame of the projects of the UNESCO chair of digital anatomy created recently at the Descartes University.The manual segmentation of 1640 anatomical slices was achieved with the Winsurf ® software producing an interactive 3D vectorial model of the heart and surrounding anatomy. Eighty four anatomical structures were reconstructed, including the heart and its vessels (27 structures), trachea, oesophagus, lungs, aortic arch, superior vena cava, azygos system, inferior vena cava, right and left kidneys, skeletal system (58) structures including: sternum, xiphoid process, clavicles, ribs, costal cartilage, thoracic vertebrae, intervertebrales discs, sacrum, hip bones, and femurs) and skin. The obtained 3D vectorial model was exported in 3D PDF format, producing a true virtual dissection tool through the Acrobat's interface: the anatomical structures can be individually and interactively manipulated as 84 separated 3D objects. 3D labels can be added with the name of each anatomical element. This new computerized virtual dissection table is a simple and powerful learning tool for students and anatomy teachers. It is also the basis of future simulation tools for surgeon's training

BACKGROUND: Cutaneous carcinosarcoma is a rare biphasic tumor comprising malignant epithelial and heterologous mesenchymal elements. Data on the clinical and histopathologic characteristics of this tumor in Asian populations are not available. The purpose of this study was to investigate the clinicopathologic and immunohistochemical features of cutaneous carcinosarcoma in the Korean population. METHODS: We retrospectively reviewed the records of 11 patients with cutaneous carcinosarcoma who were diagnosed from 2006 to 2016. RESULTS: The mean patient age at diagnosis was 71.5 years (range, 43–96 years) and there was a men predilection. The most common site of cutaneous carcinosarcoma was the head and neck (8/11, 72.7%). Histopathologically, most tumors showed a characteristic morphology consisting of two types of tumor cells, varied differentiated epithelial cells (such as basal or squamous cells) and spindle cells with transition zones between the two components. These two cell types also demonstrated variable immunohistochemical characteristics. CONCLUSION: Although the number of cases in this study was limited, our results provide valuable insight into the clinical and histopathologic characteristics of cutaneous carcinosarcoma in the Korean population.

PURPOSE: Abernethy malformation is a rare condition, which was first described in 1793 as a congenital extrahepatic porto-systemic shunt (CEPS) directing splanchnic blood flow into the inferior vena cava. Eighty cases have been published so far that reported CEPS, while in Korea, very few cases have been reported. Through this study, we present 6 cases of patients diagnosed with CEPS at Samsung Medical Center and compare these with other such cases published in France and China. METHODS: We reviewed clinical, laboratory, and imaging data of 6 children with CEPS in our pediatric clinic between 2004 and 2017. RESULTS: A total of 6 children with CEPS was included in this study, namely, one with type 1a, two with type 1b, and three with type 2 CEPS. The most common presenting symptom was gastrointestinal bleeding (50.0%). Therapeutic interventions included shunting vessel ligation (16.7%) in type 2 CEPS and liver transplantation (16.7%) in type 2 CEPS patient with suddenly developed hepatic encephalopathy. CONCLUSION: There is no consensus guideline for the optimal management of patients with CEPS. Large-sample studies regarding CEPS are needed to evaluate the characteristics of patients with CEPS and determine the treatment guideline for CEPS.

Athletic performance is a complex multifactorial trait involving genetic and environmental factors. The heritability of an athlete status was reported to be about 70% in a twin study, and at least 155 genetic markers are known to be related with athlete status. Mitochondrial DNA (mtDNA) encodes essential proteins for oxidative phosphorylation, which is related to aerobic capacity. Thus, mtDNA is a candidate marker for determining physical performance. Recent studies have suggested that polymorphisms of mtDNA are associated with athlete status and/or physical performance in various populations. Therefore, we analyzed mtDNA haplogroups to assess their association with the physical performance of Korean population. The 20 mtDNA haplogroups were determined using the SNaPshot assay. Our result showed a significant association of the haplogroup F with athlete status (odds ratio, 3.04; 95% confidence interval, 1.094 to 8.464; p = 0.012). Athletes with haplogroup F (60.64 ± 3.04) also demonstrated a higher Sargent jump than athletes with other haplogroups (54.28 ± 1.23) (p = 0.041). Thus, our data imply that haplogroup F may play a crucial role in the physical performance of Korean athletes. Functional studies with larger sample sizes are necessary to further substantiate these findings.
