Background:
Metabolic syndrome (MetS) refers to a group of risk factors that cause health problems, such as obesity, diabetes, dyslipidemia, and hyperglycemia. MetS is characterized by insulin resistance, which leads to abnormal insulin sensitivity. Cirsium japonicum var. maackii (CJ) is perennial herbaceous species found in Asia that exhibits antioxidant, antidiabetic, antitumor, antifungal, and anti-inflammatory activities. In this study, we aimed to measure the effects of CJ on MetS by improving insulin resistance in a db/db type 2 diabetes mouse model. After administrating CJ extract (CJE) for db/db mouse for 6 weeks, we measured with the evaluation of Insulin resistance, lipid profiles, histological analysis of liver, damage of liver and kideny.
Results:
The results showed that CJE was effective in reducing body weight and fat mas and showed a positive effect on lowering blood glucose and improving insulin sensitivity. CJE improved dyslipidemia by increasing serum-HDL levels and decreasing serum-LDL levels. In addition, CJE reduced liver and kidney damage in histological analysis.
Conclusions
These results demonstrate the anti-diabetic effects of CJE and suggest its potential for improving MetS.Therefore, CJE may have potential values as a functional food material for managing MetS.
2.Alveolar Soft Part Sarcoma of the Larynx: A Case Report
Korean Journal of Head and Neck Oncology 2025;41(1):1-4
Alveolar soft part sarcoma (ASPS) is a rare and potentially aggressive soft tissue malignancy that primarily affects teenagers and young adults. It is generally associated with a high incidence of metastasis early in the disease course, with brain metastases occurring more frequently than in other high-grade sarcomas. ASPS most commonly arises in the extremities, particularly the lower limbs, while approximately one-fourth of cases occur in the head and neck region, with typical sites including the tongue and orbit, although involvement of the larynx is very rare. In this case report, we present a rare case of ASPS located in the larynx, accompanied by a review of the literature. This case emphasizes that ASPS should be considered in the differential diagnosis when evaluating solid and/or vascular laryngeal masses in the young population, and underscores the necessity of early surgical intervention.

Journal of the Korean Ophthalmological Society 2024;65(3):181-193
Purpose:
This study investigated the causative microorganisms, antibiotic susceptibility, and risk factors of infectious keratitis over the past 10 years.
Methods:
Data from patients with infectious keratitis who underwent microbial culture tests from 2012 to 2021, obtained from anonymized data systems, were analyzed. Microbial culture results and antibiotic susceptibility profiles were examined. A retrospective analysis of the medical records of patients with infectious keratitis during the same period was conducted to investigate the clinical characteristics and risk factors.
Results:
Data from 1,837 cases of infectious keratitis were extracted from anonymized records. The culture positive rate among patients was 46.0% (1,137/2,474), with coagulase-negative Staphylococcus (CoNS) being the most common causative organism (27.8%). Increased resistance to cefazolin and cefotaxime was observed in gram-negative bacteria, while there were no significant temporal changes in quinolone resistance in gram-positive or negative bacteria. A retrospective medical record analysis of 288 cases revealed that older patients, as well as those with an initial corrected visual acuity < 0.1, a history of ocular surgery, pre-existing ocular conditions, prior steroid eye drops, or glaucoma eye drops, had significantly higher rates of culture positivity. Multivariate analysis identified risk factors for severe keratitis requiring surgical intervention as a symptom-to-presentation period of 7 days or longer (p = 0.048) and pre-existing ocular conditions (p = 0.040).
Conclusions
CoNS was the most common microorganism causing infectious keratitis over the past decade. There has been an increase in resistance to cephalosporin antibiotics among gram-negative bacteria. Patients with pre-existing ocular conditions may require surgical intervention, so infectious keratitis in these patients requires greater attention.
