  • Objectives: We aim to observe the relation of body mass index (BMI) and the indicators of oral health. Methods: 400 subjects participated in the study. The BMI values are calculated from the height and weight. For the tongue diagnosis, we used the tongue imaging device to analyze the color, tongue coating, and tooth marks. We measured the concentration of hydrogen sulfide (H2S) and methyl mercaptan (CH3SH) to evaluate the halitosis. The dry mouth was evaluated through the measurement of saliva secretion and with the questionnaire asking the frequency of dry mouth. Results: The BMI values were significantly higher in the group with light-white and blue-purple colored tongue, and significantly lower for lightly-coated tongue. However, the correlation of BMI and the amounts of saliva secretion was not significant as well as in the correlation of BMI and the concentration of H2S, CH3SH. In tongue diagnosis, the subjects who had blue-purple colored tongue also had significantly higher H2S and CH3SH, but tendency of lower saliva secretion. Conclusion: We obtain data showing that BMI value and the indicators of oral health including tongue diagnosis have meaningful correlation.

  • Purpose: The purpose of this study is to seek in-depth perspectives of stakeholders on the necessity and specific criteria for designating a specialized hospital for urologic diseases. Methods: Eight participants experts in urology medicine and specialized hospital system were divided into four groups. Following the semi-structured guidelines, an in-depth interview was conducted twice and a focus group discussion was conducted three times. All the interviews were transcribed verbatim and analyzed. Results: The majority of participants predicted that there would be demand for specialized hospitals for urologic diseases. The criteria of designating a specialized hospital, such as the number of hospital beds and quality of health care, have to be modified in consideration of the specificity of urology. The introduction of a specialized hospital would improve the healthcare delivery system, positively affecting hospitals and patients. Furthermore, government support is essential for the maintenance of specialized hospital systems as urology hospitals experience difficulties in generating profits. Conclusion: This study is expected to be used as base data for introducing and operating a specialized hospital for urologic diseases. In addition, it is expected that the methodology and results of this study would encourage follow-up studies on specialized hospitals and provide guidelines to evaluate the effectiveness of such hospitals in other medical fields.

  • Background/Objectives: The aim of this national population-based retrospective study was to analyze the status and treatment outcome in patients with hypopharyngeal cancer. Materials & Methods: Participants were included in the KNHIS national sample cohort who received a KNHIS health check-up in 2008 and 2009, and we followed these individuals until 2017. Patients were defined as having hypopharynx cancer if they had admissions records for hypopharynx cancer in their national health insurance data from 2010 to 2017. Results: The study cohort included 3,922 patients. According to our nationwide data, 3,533(90.1%) were male with a median age of 65.03±11.04 years at the time of diagnosis. Among parametric models for hypopharyngeal cancer prognosis, old age (Hazard ratio [HR]:1.92; 95% confidence interval[CI]:1.76-2.09), female (HR:0.77; 95% CI:0.66-0.89), and low socioeconomic status (HR:1.216; 95% CI:1.114-1.327) were significantly associated with survival. Compared with concurrent chemoradiotherapy, patients who received no treatment (HR, 1.88; 95% CI, 1.31-2.70), neoadjuvant chemotherapy followed by surgery (HR, 1.21; 95% CI, 1.04-1.41), and chemotherapy alone (HR, 1.16; 95% CI, 1.03-1.27) showed poor prognosis in hypopharyngeal cancer. Conclusion: Our data indicated that age, sex, and income were significant predictors of lifetime survival in patients with hypopharyngeal cancer. Treatment modalities were also associated with prognosis. The data have implications for treatment investigations and prevention strategies.

  • This study was conducted to suggest the Cudrania tricuspidata leaf and Achyranthes japonica Nakai Complex (CAC) possibility of use as a functional natural material for improving bone disease. Cudrania tricuspidata leaf and Achyranthes japonica Nakai were mixed in the same amount, extracted with hot water, and then powdered and used in the study. After, the cytotoxicity of CAC for osteoblasts (MG63 cell), osteoclasts (differentiated RAW264.7 cell), and macrophages (RAW264.7 cell) were evaluated by MTT assay, and ALP assay and TRAP assay were performed to confirm the differentiation capacity of osteoblasts and osteoclasts, respectively. In addition, the anti-inflammatory effect in macrophages was evaluated by ELISA, qRT-PCR, and western blot assay. CAC did not proliferated osteoblasts and osteoclasts, but increased ALP activity against osteoblasts differentiation and decreased TRAP activity against osteoclasts differentiation. CAC did not proliferated macrophages but decreased nitric oxide production. Also, decreased NOS2, IL1B, IL6, PTGS2, and TNFA gene expression, and JNK and p38 protein phosphorylation in a concentration-dependent manner, but ERK protein phosphorylation was not changed. As a result, CAC increased the differentiation and activation of osteoblasts, inhibited the differentiation and activation of osteoclasts, and regulated the expression of inflammatory cytokines in macrophages. Therefore, it is thought that CAC can be used as a functional natural material that prevents bone disease and has an anti-inflammatory effect.

  • Objective : The present study comparatively analyzed the anti-obesity effect of Arctium lappa L. roots with and without microwave processing. Methods : Four HFD groups except for the Normal group (n=8) were allocated: Control, microwave-processed dried Arctium lappa L. roots (MAL) extract 400 mg/kg/d (MAL400), MAL extract 800 mg/kg/d (MAL800), and the dried Arctium lappa L. roots (DAL) extract 800 mg/kg/d (DAL800). The efficacy of MAL and DAL was confirmed in terms of the serum biochemical index, protein expressions related to the synthesis of triglyceride (TG) and total cholesterol (TC) and 𝛽-oxidation, and histopathological staining. Results : Both MAL and DAL treatments significantly reduced final body weight and body weight gain. MAL800 treatment significantly reduced serum TG, TC, low-density lipoprotein cholesterol, and leptin levels, but the serum high-density lipoprotein cholesterol and adiponectin concentrations were dramatically increased. In particular, leptin in the MAL800 group was reduced by 14.1% compared with the DAL800 group. Moreover, the MAL800 treatment showed an effect superior to the DAL800 treatment in the reduction of serum TC, the sirtuin 1 (Sirt1) activation, and the inhibition of 3-hydroxy-3-methyl glutaryl coenzyme A reductase (HMGCR) gene expression. In particular, unlike the DAL800 treatment, MAL treatment significantly led to the activation of peroxisome proliferator-activated receptor alpha (PPAR𝛼). Subsequently, PPAR𝛼 meaningfully regulated downstream proteins associated with 𝛽-oxidation. Conclusion : These findings suggest that Arctium lappa L. roots with microwave processing effectively ameliorate obesity through the regulation of leptin and TC and the promotion of 𝛽-oxidation compared with Arctium lappa L. roots without microwave processing.

  • Objectives To compare the therapeutic effect of ultrasound guided soyeom pharmacopuncture therapy and unguided soyeom pharmacopuncture therapy on cervical facet joint of patient who have cervical pain caused by traffic accidents. Methods The study was planned as a retrospective study that analyzes the patient's medical records. We analyzed medical records of 20 patients with acute cervical pain caused by traffic accidents from April 1, 2022 to May 31, 2022. 10 patients (Group A) were treated ultrasound guided soyeom pharmacopuncture therapy on cervical facet joint, 10 patients (Group B) were treated unguided soyeom pharmacopuncture therapy on cervical facet joint. We used visual analogue scale (VAS) and neck disability index (NDI) to evaluate improvements in cervical functions and pain, five point Likert scale to estimate patient's satisfaction. We used the IBM SPSS Statistics version 25 program (IBM Co., Armonk, NY, USA) for statistical analysis. Results Group A showed a significant decrease in the VAS on the 5th day of the soyeom pharmacopuncture therapy (p=0.001). However, there was no statistically significant difference of VAS between two groups (p=0.142). Group A showed significant decrease in the NDI on the 5th day of the therapy (p=0.002). Also, there was statistically significant difference on NDI between two groups (p=0.018). Difference of five point Likert scale between two groups was not statistically significant (p=0.407). Conclusions In patients of acute cervical pain caused by traffic accidents, ultrasound guided soyeom pharmacopuncture therapy on cervical facet joint showed significant efficacy on reduction of neck disability compared with unguided therapy.

  • The incidence of rotator cuff tear is increasing rapidly due to the aging of the population and the advancement of radiological diagnosis, and so on. Recently, arthroscopic rotator cuff repair is common way of surgery, and the surgical outcome is comparable to open rotator cuff repair. Arthroscopic repair is one of the minimally invasive procedures itself and may have additional benefits of postoperative pain reduction and early functional recovery. Recently, there has been increasing interest in various methods for improving the functional recovery of patients after arthroscopic shoulder surgery. Various protocols of functional recovery after arthroscopic shoulder surgery are classified by the postoperative period, and they are being studied actively and improved at each stage. On the other hand, there are a range of methods according to the postoperative period, rehabilitation stage, characteristics of individual patients, degree of rotator cuff tear, and underlying disease. Therefore, for functional recovery after arthroscopic rotator cuff repair, it is essential to establish proper regimens for functional recovery.

  • Objectives: The purpose of this study is to evaluate anti-breast cancer and anti-inflammatory effects of Chungganhaewool-tang and Shipyeukmiyeugi-eum. Methods: MDA-MB-231 cells were used to measure cytotoxicity, Reactive oxygen species (ROS) production, protein expression amounts of Bcl-2-associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), B-cell lymphoma-extra large (Bcl-xl), Cytochrome C Caspase-3, Caspase-7, Caspase-9, Poly ADP-ribose polymerase (PARP), Nuclear factor erythroid-2-related factor 2 (Nrf2), Heme oxygenase-1 (HO-1) and NAD (P) H Quinone Oxidoreductase 1 (NQO1) to evaluate the anti-breast cancer effects of Chungganhaewool-tang (CHT) and Shipyeukmiyeugi-eum (SYE), and THP-1 cells, differentiated into macrophage and induced inflammation with Lipopolysaccharide (LPS), were used to measure production amounts of ROS, Nitric oxide (NO), and protein expression amounts of Inducible nitric oxide synthase (iNOS), Cyclooxygenase (COX-2), Interleukin-1 beta (IL-1β), Interleukin-6 (IL-6) and Tumor necrosis factor-alpha (TNF-α) to evaluate the anti-inflammatory effects of CHT and SYE. Results: CHT and SYE reduced MDA-MB-231 cell counts, increased protein expression of Bax and Cytochrome C, and decreased protein expression of Bcl-2, Bcl-xl. The protein expression amounts of Caspase-3, 7, and 9 decreased, but amounts of the active form, cleaved Caspase-3, 7, and 9, increased. In addition, PARP protein expression decreased, the amount of PARP protein in the cleaved form increased, and the amount of protein expressions of Nrf2 and HO-1 decreased, but NQO1 showed no significant difference. In THP-1 cells CHT and SYE reduced ROS and NO, and reduced protein expressions of iNOS, COX-2, IL-1, and TNF-α, but only SYE groups reduced IL-6. Conclusions: This study suggests that CHT and SYE have potential to be used as treatments for breast cancer.

  • This study divided video content of current representative YouTube channels on Chinese language education into internal and external elements for analysis. By examining these channels, this study found that they have various external and internal elements. In addition, YouTube classes also have certain distinct characteristics that are non-existent in traditional classroom or face-to-face classes, and show potential to serve as a new educational medium that can fill the gaps in existing classroom classes. However, a large number of these channels still have problems with their internal and external elements, which seem to require not only the effort and attention of the instructors creating the videos, but also considerable time and human and material resources.
