        Qing-Yu-Mu, an Herbal Formula, Reduces Hepatic Oxidative Stress in Rats Fed a High-Frying Oil Diet and Ameliorates Carbon Tetrachloride-Induced Liver Injury

        Wen-Pin Lee,Mei-Ling Li,Yun-Ta Liu,Chung-Ming Lee,Hsien-Tsung Yao 한국식품영양과학회 2021 Journal of medicinal food Vol.24 No.1

        Qing-Yu-Mu (QYM) is an herbal formula used to prevent and treat liver disease in Taiwan. In this study, the hepatoprotective effects of QYM were evaluated in two experimental models. First, rats were fed a high-frying oil (FO) diet containing 1.25% QYM for 5 weeks to investigate effects of QYM on hepatic oxidative stress and antioxidant enzyme activities. Then, protective effects of QYM on carbon tetrachloride (CCl4)-induced chronic liver injury were evaluated. Results show that QYM treatment reduced FO diet-induced hepatic lipid peroxidation and reactive oxygen species levels and increased glutathione (GSH) S-transferase activity. A higher reduced GSH/oxidized GSH (GSSG) ratio was observed after QYM treatment. Furthermore, QYM ameliorated CCl4-induced liver injury by reducing the activity of plasma alanine aminotransferase and histological lesions in the liver. QYM also increased the level of hepatic GSH and activities of GSH peroxidase and superoxide dismutase. Finally, chlorogenic acid, chrysophanol, and apigenin were found to be present in relative abundance in QYM. Results show that QYM may exhibit a hepatoprotective effect by reducing oxidative stress and increasing antioxidant activity in the liver.

        Comparison between residents with a 6-year medical program and a 7-year medical program in terms of objective structured clinical examination performance in postgraduate year training in Taiwan: a 2-group pre- and post-test non-synchronized study

        Ya-Ting Chang,Ying-Ying Yang,Chung-Pin Li,Chen-Huan Chen 한국보건의료인국가시험원 2022 보건의료교육평가 Vol.19 No.-

        Purpose In 2013, medical schools in Taiwan implemented a 6-year medical program that replaced the previous 7-year medical education program. The postgraduate year (PGY) program was also extended from 1 year to 2 years. The new program is characterized by diversified teaching, integration of medical skills, a system-oriented curriculum, and the implementation of primary care and clinical thinking training. The purpose of this study was to examine whether postgraduate residents who learned under the new program have better patient care skills than those who learned under the previous program. Methods Of 101 residents in the PGY program at Taipei Veterans General Hospital, 78 were trained in the 6-year program, while 23 were trained in the 7-year program. During the PGY training, 2 objective structured clinical examinations (OSCEs) were used to evaluate clinical reasoning, communication skills, and procedural skills at the beginning of the training and after 11 months of training, respectively. The scores of each OSCE and the rate of improvement of the pre- and post-tests were analyzed. Results Residents trained in the new program scored higher on clinical reasoning (P<0.001) and the total scores of the 3 tested skills (P=0.019) on the pre-test. In terms of improvement, residents educated in the previous system improved more in clinical reasoning than those educated in the new education system. Conclusion The new medical education program, which emphasizes clinical thinking, improved residents’ clinical skills. The PGY program was effective in improving the clinical performance of residents who were educated in the previous system.

        Negative effects on medical students’ scores for clinical performance during the COVID-19 pandemic in Taiwan: a comparative study

        Eunice Jia-Shiow Yuan,Shiau-Shian Huang,Chia-An Hsu,Jiing-Feng Lirng,Tzu-Hao Li,Chia-Chang Huang,Ying-Ying Yang,Chung-Pin Li,Chen-Huan Chen 한국보건의료인국가시험원 2023 보건의료교육평가 Vol.20 No.-

        Purpose Coronavirus disease 2019 (COVID-19) has heavily impacted medical clinical education in Taiwan. Medical curricula have been altered to minimize exposure and limit transmission. This study investigated the effect of COVID-19 on Taiwanese medical students’ clinical performance using online standardized evaluation systems and explored the factors influencing medical education during the pandemic. Methods Medical students were scored from 0 to 100 based on their clinical performance from 1/1/2018 to 6/31/2021. The students were placed into pre-COVID-19 (before 2/1/2020) and midst-COVID-19 (on and after 2/1/2020) groups. Each group was further categorized into COVID-19-affected specialties (pulmonary, infectious, and emergency medicine) and other specialties. Generalized estimating equations (GEEs) were used to compare and examine the effects of relevant variables on student performance. Results In total, 16,944 clinical scores were obtained for COVID-19-affected specialties and other specialties. For the COVID-19-affected specialties, the midst-COVID-19 score (88.51–3.52) was significantly lower than the pre-COVID-19 score (90.14–3.55) (P<0.0001). For the other specialties, the midst-COVID-19 score (88.32–3.68) was also significantly lower than the pre-COVID-19 score (90.06–3.58) (P<0.0001). There were 1,322 students (837 males and 485 females). Male students had significantly lower scores than female students (89.33–3.68 vs. 89.99–3.66, P=0.0017). GEE analysis revealed that the COVID-19 pandemic (unstandardized beta coefficient=-1.99, standard error [SE]=0.13, P<0.0001), COVID-19-affected specialties (B=0.26, SE=0.11, P=0.0184), female students (B=1.10, SE=0.20, P<0.0001), and female attending physicians (B=-0.19, SE=0.08, P=0.0145) were independently associated with students’ scores. Conclusion COVID-19 negatively impacted medical students' clinical performance, regardless of their specialty. Female students outperformed male students, irrespective of the pandemic.
