  • Background: The incidence and clinical importance of nonalcoholic fatty liver disease (NAFLD) has emerged. However, effective therapeutic strategies for NAFLD have yet to be found. Panax ginseng (P. ginseng) is a traditional herb in Eastern Asia with therapeutic effects in many chronic disorders. However, the precise effects of ginseng extract on NAFLD are currently unknown. In present study, the therapeutic effects of Rg3-enriched red ginseng extract (Rg3-RGE) on the progression of NAFLD were explored. Methods: Twelve-week-old C57BL/6 male mice were fed a chow or western diet supplemented with high sugar water solution with or without Rg3-RGE. Histopathology, immunohistochemistry, immunofluorescence, serum biochemistry, western blot analysis, and quantitative RT-PCR were used for in vivo experiment. Conditionally immortalized human glomerular endothelial cell (CiGEnC) and primary liver sinusoidal endothelial cells (LSECs) were used for in vitro experiments. Results: Eight weeks of Rg3-RGE treatment significantly attenuated the inflammatory lesions of NAFLD. Furthermore, Rg3-RGE inhibited the inflammatory infiltrate in liver parenchyma and the expression of adhesive molecules to LSECs. Moreover, the Rg3-RGE exhibited similar patterns on the in vitro assays. Conclusion: The results demonstrate that Rg3-RGE treatment ameliorates NAFLD progression by inhibiting chemotaxis activities in LSECs.

  • Living creatures possess long-conserved mechanisms to maintain homeostasis in response to various stresses. However, chronic and continuous exposure to stress can result in the excessive production of stress hormones, including catecholamines, which have harmful effects on health. Studies on the relationship between the sympathetic nervous system (SNS) and cancer have been conducted based on the traditional hypothesis that stress can promote cancer progression. Many preclinical and epidemiological studies have suggested that the regulation of ${\beta}$-adrenergic signaling, which mediates SNS activity, can suppress the progression of solid tumors. SNS activation has highly pleiotropic effects on tumor biology, as it stimulates oncogenes, survival pathways, the epithelial - mesenchymal transition, and invasion. Moreover, it inhibits DNA repair and programmed cell death and regulates the tumor microenvironment, including immune cells, endothelial cells, the extracellular matrix, mesenchymal cells, and adipocytes. Although targeted therapies on the molecular basis of tumor proliferation are currently receiving increased attention, they have clinical limitations, such as the compensatory activation of other signaling pathways, emergence of drug resistance, and various side effects, which raise the need for pleiotropic cancer regulation. This review summarizes the effects of the SNS on the development and progression of cancer and discusses the clinical perspectives of ${\beta}$-blockade as a novel therapeutic strategy for this disease.

  • Alzheimer's disease (AD) is the most prevalent form of neurodegenerative disease associated with aging in the human population. This disease is characterized by the following 4 structural changes : Atrophy of the Cortex, Parasympathetic, and other neural cells, the existence of Neurofibrillary tangles (NFTs), and the accumulation of Senile plaques. NFTs and Senile plaques is known to be the index of this disease. Senile plaques disturbs the neutro transmission and depletes of Acetylcholine. So, Recovery of Acetylcholine is the primal objective for treating Alzheimer's disease. So, Inhibiting the activity of Acetylcholine Esterase (AChE), which causes the hydrolysus of acetylcholine into choline and acetate, can be seen as a key role for treating Alzheimer's disease. Increasing body of evidence has been demonstrated that Bee Venom Acupuncture (BV) could compete with complex protein involving in multiple step of $NF-_{\kappa}B$ activation and exert the anti -inflammatory potential of combined inhibition of the prostanoid and nitric oxide synthesis systems by inhibition of IKK and $NF-_{\kappa}B$. The effect of BV through behavioral tests after memory impairment induced by Scopolamine. We examined the improving effect of BV on the Scopolamine (1 mg/Kg, i.p.)-induced memorial impairment using passive avoidance response and water maze tests in the mice. BV (0.84, $1.67\;{\mu}g/ml$) reversed the Scopolamine-induced memorial impairment in dose dependent manner. This study therefore suggests that BV acupuncture method may be useful for prevention of development or progression of AD.

  • Chylomicron retention disease, also known as Anderson's disease, is a rare hereditary hypocholesterolemic disorder, recessive inherited, characterized by nonspecific symptoms as abdominal distension, steatorrhea, and vomiting associated with failure to thrive. We describe a patient with failure to thrive, chronic diarrhea and steatorrhea who the diagnosis of chylomicron retention disease was established after several months of disease progression. The genetic study confirmed a homozygosity mutation in SAR1B gene, identifying a mutation never previous described [c.83_84delTG(p.Leu28Argfs*7)]. With this case report the authors aim to highlight for this very rare cause of failure to thrive and for the importance of an attempting diagnosis, in order to start adequate management with low fat diet supplemented with fat-soluble vitamins, reverting the state of malnutrition and avoiding possible irreversible and desvantating complications.

  • Pompe disease (glycogen storage disease type II) is an autosomal recessive disorder caused by deficiency of acid-${\alpha}$-glucosidase (GAA) resulting in lysosomal glycogen accumulation in multiple tissue, particularly cardiac and skeletal muscle. The classic infantile form of Pompe disease is characterized by marked cardiomegaly, respiratory failure and severe generalized hypotonia. Most patients die from cardiorespiratory failure or respiratory infection within the first year or two of life without treatment. A "non-classic" phenotype presents with less severe clinical feature and slow progression of disease. We report two patients with non-classic infantile Pompe disease from one family manifested hypertrophic cardiomyopathy and progressive proximal weakness.

  • Alexander disease is a rare degenerative leukodystrophy caused by dominant mutations in glial fibrillary acidic protein (GFAP). The neonatal form of Alexander disease may manifest as frequent and intractable seizures or obstructive hydrocephalus, with rapid progression leading to severe disability or death within two years. We report a case of a 50-day-old male who presented with intractable seizures and obstructive hydrocephalus. His initial magnetic resonance imaging (MRI) suggested a tumor-like lesion in the tectal area causing obstructive hydrocephalus. Despite endoscopic third ventriculostomy and multiple administrations of antiepileptic drugs, the patient experienced intractable seizures with rapid deterioration of his clinical status. After reviewing serial brain MRI scans, Alexander disease was suspected. Subsequently, we confirmed the de novo missense mutation in GFAP (c.1096T>C, Y366H). Although the onset was slightly delayed from the neonatal period (50 days old), we concluded that the overall clinical features were consistent with the neonatal form of Alexander disease. Furthermore, we also suspected that a Y366 residue might be closely linked to the neonatal form of Alexander disease based on a literature review.

  • Objectives: The purpose of this study was to confirm the relationship between socioeconomic characteristics and the prevalence of periodontal disease, with a focus on employment status, in a representative sample of Korean adults aged 19-39 years. Methods: Data were obtained from 3,178 adults who completed the Korean National Health and Nutrition Examination Survey, health-related questionnaires, and an oral examination. Socioeconomic, demographic, and oral health-related behavior data were adopted as independent variables. The chi-square test was used to assess differences in the distribution of socioeconomic status, oral health behavior, and nutrition factors according to employment status. Logistic regression analysis was performed to confirm the relationships between the prevalence of periodontitis and the related variables. Results: Significant differences in sex, educational level, income, marital status, smoking status, prevalence of periodontitis, number of dental check-ups in a year, and unmet dental care were confirmed according to employment status. The prevalence of periodontal disease was not significantly related to employment status. Conclusions: These results suggest a significant difference in periodontal disease according to socioeconomic factors in Korean adults. However, the prevalence of periodontal disease was not related to employment status. To prevent the progression of periodontal disease, attention should be paid to oral health, time available for dental treatment, smoking cessation, and use of floss.

  • Purpose: Pediatric Crohn's disease (CD) is directly related to growth and has a high probability of requiring surgical intervention(s); therefore, more active treatment for CD is required for children. This study investigated the impact of biologics on growth and disease course associated with surgery. Methods: This was a retrospective cohort study involving patients diagnosed with CD at the Seoul National University Children's Hospital (Seoul, Korea) between January 2006 and October 2017. The aim was to determine the characteristics of pediatric patients with CD and whether biologics affected growth and the surgical disease course. Results: Among patients who underwent surgery for CD, the mean number of operations per patient was 1.89. The mean time from initial diagnosis to surgery was 19.3 months. The most common procedure was fistulectomy (34%), followed by incision and drainage (25%). In all patients, the use of biologics increased the height (p=0.002) and body mass index (BMI) (p=0.005). Among patients who underwent surgery, height (p=0.004) and BMI (p=0.048) were increased in the group using biologics. Patients who used biologics exhibited a low operation rate only within 2 years after diagnosis, with no differences thereafter (p=0.027). Conclusion: Although biologics could not mitigate the operation rate in pediatric patients who underwent surgery for CD, biological therapy delayed disease progression within 2 years of disease onset. Additionally, biologics conferred growth and BMI benefits in this window period. Therefore, it may be helpful to use biologics for optimal growth in pediatric patients with a high probability of undergoing future surgery.

  • Purpose: To assess parent perspectives of the current and potential future tests for their child with inflammatory bowel disease (IBD). Methods: New Zealand parents of a child with IBD were invited to complete an anonymous online survey. Experiences relating to their child's blood or faecal tests, medical imaging (abdominal ultrasound [US], abdominal computerised tomography [CT] and magnetic resonance enterography) and colonoscopy were collected. Perceived attitudes to potential future testing of urine, saliva, and breath, were sought. Results: Twenty-eight parents, 93% female completed the survey, and 86% were aged between 35 and 54 years. Baseline information was provided by parents for 27 of 28 children, 70.3% had Crohn's disease with a mean disease duration of 2.67 years. Blood tests were the most requested and completed tests, while CT was the least ordered and most refused test. Colonoscopy was rated as the least comfortable and generated the most worry. Explanation of test significantly improved parent's levels of understanding when their child had blood, faecal, imaging (US) or colonoscopy tests. Providing an explanation, test invasiveness and the impact of the blood results may have on their child's treatment significantly improved parents' comfort levels. However, explanation of colonoscopy generated a significant parental concerns. Saliva, urine and blood tests were chosen as the most preferred disease monitoring tests. Conclusion: Parents preferred any tests less invasive than colonoscopy for monitoring their child's IBD. Although providing explanation of their child's tests enhanced parents' understanding, it can also affect parents' levels of concern and comfort.
