Malignant melanoma develops from the melanocyte and the most common primary site is skin, followed by mucosa and retina. Even though any other tissue where melanocytes reside could be the primary site of the malignant melanoma, the one developed in the mediastinum is rarely reported. We experienced a patients of 54 years old woman whose initial symptom was progressive dyspnea for one month, and proved to have the anterior mediastinal mass with pleural effusion and the small mass in the abdominal soft tissue. The needle aspiration biopsy from the mediastinal mass showed the consistent findings with malignant melanoma. We concluded the mediastinum was the primary site of the malignant melanoma of this patient because we couldn't find any other evidence of primary tumor in skin, oral and gastrointestinal mucosa, and retina. She has been treated with combined chemotherapy with dacarbazine, cisplatin and vinblastine. Her symptom was improved after chemotherapy and follow up chest CT after three cycles of chemotherapy showed the decreased tumor size in the mediastinum.

The present study was conducted to evaluate the food and nutrients intakes of stomach cancer patients in the Daegu and Gyeongbuk areas in order to find out the dietary risk factors for stomach cancer. The subjects of the study were 102 patients who had recently been diagnosed with stomach cancer at the Gyeongbuk National University Hospital. The control subjects were 105 people including patients from the Department of Orthopedic Surgery and healthy volunteers who did not have any gastrointestinal diseases. Estimates of nutrients intakes were determined from the food intake frequency data obtained by individual interviews using questionnaires. The mean daily calorie intakes of the control and the case groups were not significantly different. However the energy intake from protein was significantly higher in the case group as compared to the control group. With regard to the nutrients intakes, the case subjects consumed significantly higher amounts of nutrients such as protein, calcium, sodium, phosphorus and niacin than the control group. The case group showed a tendency to consume higher amount of protein, fat, calcium and iron from animal food sources. In the present study dietary factors which were suspected as being risk factors for stomach cancer included high consumption of animal foods, specific nutrients such as protein, sodium and niacin, specific food groups such as meat, spices, and low consumption of fruits and mushrooms. Therefore, it is recommended that more extensive and systematic surveys be conducted to confirm the risk factors for stomach cancer, taking into consideration the dietary cultural characteristics of this region.

Rab25, a member of the Rab11 small GTPase family, is central to achieving cellular polarity in epithelial tissues. Rab25 is highly expressed in epithelial cells of various tissues including breast, vagina, cervix, the gastrointestinal tract, and skin. Rab25 plays key roles in tumorigenesis, mainly by regulating epithelial differentiation and proliferation. However, its role in skin physiology is relatively unknown. In this study, we demonstrated that Rab25 knock-out (KO) mice show a skin barrier dysfunction with high trans-epidermal water loss and low cutaneous hydration. To examine this observation, we investigated the histology and epidermal differentiation markers of the skin in Rab25 KO mice. Rab25 KO increased cell proliferation at the basal layer of epidermis, whereas the supra-basal layer remained unaffected. Ceramide, which is a critical lipid component for skin barrier function, was not altered by Rab25 KO in its distribution or amount, as determined by immunohistochemistry. Notably, levels of epidermal differentiation markers, including loricrin, involucrin, and keratins (5, 14, 1, and 10) increased prominently in Rab25 KO mice. In line with this, depletion of Rab25 with single hairpin RNA increased the expression of differentiation markers in a human keratinocyte cell line, HaCaT. Transcriptomic analysis of the skin revealed increased expression of genes associated with skin development, epidermal development, and keratinocyte differentiation in Rab25 KO mice. Collectively, these results suggested that Rab25 is involved in the regulation of epidermal differentiation and proliferation.

Gastroesophageal reflux disease (GERD) is a gastrointestinal disorder in which stomach contents reflux into the esophagus, causing complications such as mucosal damage. The purpose of this study was to determine the effect of Rhei Rhizoma and Scutellariae Radix mixture (RS) in chronic acid reflux esophagitis (CARE), one of the GERD. After inducing reflux esophagitis through surgery, the group was separated and the drug was administered for 2 weeks; Normal rats (Normal, n=8), chronic acid reflux esophagitis rats (Control, n=8), tocopherol 30 mg/kg-treated chronic acid reflux esophagitis rats (Toco, n=8), Rhei Rhizoma and Scutellariae Radix mixture 100 mg/kg-treated chronic acid reflux esophagitis rats (RSL, n=8), Rhei Rhizoma and Scutellariae Radix mixture 200 mg/kg-treated chronic acid reflux esophagitis rats (RSH, n=8). Gross lesion of esophageal mucosa after RS treatment showed a superior enhancement compared with that of Control group. Additionally, RS significantly decreased the levels of MPO and MDA, effectively inhibited NADPH oxidase, and regulated the expression of the AMPK/LKB1/NF-κB pathway. Moreover, it significantly increased the expression of tight junction proteins. Taken together, RS not only alleviates inflammation of the esophageal mucosa via the AMPK/LKB1/NF-κB pathway by reducing oxidative stress, but also improves esophageal function by modulating tight junction proteins.

Background/Aims Delayed gastric emptying (GE) is associated with high morbidity and mortality in subjects with diabetes. The aim of this study is to investigate associations between GE time and the major cardiovascular events (coronary heart diseases and ischemic stroke) in diabetic subjects with upper gastrointestinal (UGI) symptoms. Methods Among 259 subjects with chronic UGI symptoms who underwent gastric emptying study (GES) over 13 years, 122 diabetic subjects without gastric surgery and/or rapid GE were enrolled in this study. We also gathered data about baseline demographics, clinical characteristics, estimated GE half-time (GE T½) and incidence of cardiovascular events following GES. Results The mean age of subjects was 64.0 ± 17.4 years. There were 86 women and 104 subjects with type 2 diabetes. There were 52 (42.6%) subjects with normal GE, 50 (41.0.%) subjects with mild delayed GE, and 20 (16.4%) subjects with marked delayed GE. During follow-up (median, 207 weeks), cardiovascular events occurred in 7 (13.5%) subjects with normal GE, 4 (8.0%) subjects with mild delayed GE and 7 (35.0%) subjects with marked GE (P = 0.015). Univariate analysis showed that GE T½ was significantly associated with incidence of cardiovascular events (crude OR, 1.74; 95% CI, 1.12-2.69; P = 0.014). In a multivariate model, association between GE T½ and incidence of cardiovascular events remained statistically significant after adjustment for baseline characteristics and comorbidities (adjusted OR, 1.94; 95% CI, 1.21-3.12; P = 0.006). Conclusion A delay of GE was associated with an increased incidence of cardiovascular events in diabetic subjects with chronic UGI symptoms.

Purpose: An underlying factor for the failure of several clinical trials of anti-epidermal growth factor receptor (EGFR) therapies is the lack of an effective method to identify patients who overexpress EGFR protein. The quantitative dot blot method (QDB) was used to measure EGFR protein levels objectively, absolutely, and quantitatively. Its feasibility was evaluated for the prognosis of overall survival (OS) of patients with gastric cancer. Materials and Methods: Slices of 2×5 ㎛ from formalin-fixed paraffin-embedded gastric cancer specimens were used to extract total tissue lysates for QDB measurement. Absolutely quantitated EGFR protein levels were used for the Kaplan-Meier OS analysis. Results: EGFR protein levels ranged from 0 to 772.6 pmol/g (n=246) for all gastric cancer patients. A poor correlation was observed between quantitated EGFR levels and immunohistochemistry scores with ρ=0.024 and P=0.717 in Spearman's correlation analysis. EGFR was identified as an independent negative prognostic biomarker for gastric cancer patients only through absolute quantitation, with a hazard ratio of 1.92 (95% confidence interval, 1.05-3.53; P=0.034) in multivariate Cox regression OS analysis. A cutoff of 208 pmol/g was proposed to stratify patients with a 3-year survival probability of 44% for patients with EGFR levels above the cutoff versus 68% for those below the cutoff based on Kaplan-Meier OS analysis (log rank test, P=0.002). Conclusions: A QDB-based assay was developed for gastric cancer specimens to measure EGFR protein levels absolutely, quantitatively, and objectively. This assay should facilitate clinical trials aimed at evaluation of anti-EGFR therapies retrospectively and prospectively for gastric cancer.

Objectives: To compare the effectiveness and safety of East Asian traditional medicine treatments (EATMT) versus conventional management in patients following heart valve replacement surgery. Methods: We searched several databases, including the Korean Studies Information Service System, PubMed, China National Knowledge Infrastructure, and Citation Information by NII. The search range included randomized controlled trials from each first issue until June 27, 2021. Two review authors independently extracted the data. We assessed the risk of systematic errors by evaluating risk domains using the "Risk of bias" tool. Results: We included 5 trials in the review. In the EATMT, the investigators reported significant improvements in reshaping of the heart structure: left ventricular end diastolic diameter (MD -4.43, 95% CI -6.06 to -2.79; 130 participants; 2 studies; high evidence). Comparisons with usual care revealed a significant decrease in gastrointestinal complications rate (OR 0.30, 95% CI 0.20 to 0.47; 503 participants; 2 studies; high evidence). We assessed 4 studies as having a low risk of bias and 1 study as having a high risk of bias. Conclusion: This systematic review suggests that East Asian traditional medicine interventions may be effective in preventing and alleviating complications, but we found evidence of important trade-offs between known benefits and known adverse effects in cardiac dysfunction and inflammation following heart valve replacement. Consequently, additional high-quality studies should be conducted.
