28 GPT-4 can pass the Korean National Licensing Examination for Korean Medicine Doctors 장동엽, 윤태림, 이충열, 권영규, 김창업 2023.12.15 ~ 학회지
Traditional Korean medicine (TKM) emphasizes individualized diagnosis and treatment. This uniqueness makes AI modeling difficult due to limited data and implicit processes. Large language models (LLMs) have demonstrated impressive medical inference, even without advanced training in medical texts. This study assessed the capabilities of GPT-4 in TKM, using the Korean National Licensing Examination for Korean Medicine Doctors (K-NLEKMD) as a benchmark. The K-NLEKMD, administered by a national organization, encompasses 12 major subjects in TKM. GPT-4 answered 340 questions from the 2022 K-NLEKMD. We optimized prompts with Chinese-term annotation, English translation for questions and instruction, exam-optimized instruction, and self-consistency. GPT-4 with optimized prompts achieved 66.18% accuracy, surpassing both the examination’s average pass mark of 60% and the 40% minimum for each subject. The gradual introduction of language-related prompts and prompting techniques enhanced the accuracy from 51.82% to its maximum accuracy. GPT-4 showed low accuracy in subjects including public health & medicine-related law, internal medicine (2), and acupuncture medicine which are highly localized in Korea and TKM. The model’s accuracy was lower for questions requiring TKM-specialized knowledge than those that did not. It exhibited higher accuracy in diagnosis-based and recall-based questions than in intervention-based questions. A significant positive correlation was observed between the consistency and accuracy of GPT-4’s responses. This study unveils both the potential and challenges of applying LLMs to TKM. These findings underline the potential of LLMs like GPT-4 in culturally adapted medicine, especially TKM, for tasks such as clinical assistance, medical education, and research. But they also point towards the necessity for the development of methods to mitigate cultural bias inherent in large language models and validate their efficacy in real-world clinical settings.
27 Phlomidis Radix Extract Alleviates Paclitaxel-Induced Neuropathic Pain by Modulating Spinal TRPV1 in Mice 박근태, 고성규, 김우진 2023.11.10 ~ 학회지
Paclitaxel is a chemotherapeutic drug reported to have excellent activity against tumors; however, various side effects, including peripheral neuropathy, limit its use in some cases. In this study, the effect of Phlomidis radix (P.Radix) extract was assessed on paclitaxel-induced cold and mechanical peripheral neuropathy in mice. Multiple paclitaxel injections (accumulative dose of 8 mg/kg, i.p.) induced increased behavioral responses to cold and mechanical stimuli in mice from D10 to D21 after the first paclitaxel injection. Cold and mechanical stimuli were performed by acetone drop and von Frey filament, respectively. Oral administrations of 25% ethanol extract of P.Radix (300 and 500 mg/kg) relieved cold and mechanical pain in a dose-dependent manner. Furthermore, among the various transient receptor potential (TRP) cation channel subfamilies, paclitaxel upregulated the spinal gene expression of transient receptor potential vanilloid 1 (TRPV1) and melastatin 4 (TRPM4), but not ankyrin 1 (TRPA1). However, 500 mg/kg but not 300 mg/kg of P.Radix extract significantly downregulated the gene expression of TRPV1 but not TRPM4. Among the components of P.Radix, sesamoside was identified and quantified by high-performance liquid chromatography (HPLC), and the administration of sesamoside (7.5 mg/kg, i.p.) showed a similar analgesic effect to 300 mg/kg P.Radix. These results suggest that P.Radix and sesamoside should be considered when treating paclitaxel-induced neuropathic pain.
26 Study on Physiological Understanding about Internal Six-qi and Its Modern Approaches 김병수 2023.10.25 ~ 학회지
Six-qi theory is an important concept in Korean medicine. Traditionally, Six-qi theory has been used pathologically. However, it could be more valuable when applied from a physiological perspective. The external Six-qi theory is an analysis of the external environment such as the climate, but the internal Six-qi theory is an analysis of the internal environment of the human body. The internal environment of the human body is considered to be the condition of extracellular fluid (ECF). The internal Six-qi can be understood by the condition of extracellular fluid. In particular, among the internal Six-qi, cold-heat and dry-dampness are well reflected in the condition of extracellular fluid. In addition, analyzing the condition of the internal Six-qi through medical inquiry would be helpful in more practical clinical treatment. A questionnaire about cold and heat could determine the intensity of the body's metabolism, and a questionnaire about dryness and moisture could determine the level of body fluids in the body.
25 A 8-week, randomized, double-blind, placebo-controlled human trial to evaluate the efficacy and safety of Saccharum officinarum wax alcohols (Policosanol) on improvement of blood cholesterol 김하림, 김예슬, 류도곤, 이금산, 권강범 외 2023.06.30 ~ 학회지
Background
The prevalence of atherosclerotic cardiovascular disease appears to be reduced, according to a large body of research, by lowering blood levels of the ratio of low-density lipoprotein cholesterol (LDL-C)/ high-density lipoprotein cholesterol (HDL-C), triglyceride (TG)/HDL-C, and LDL-C.

Objective
The objective of the investigation was to determine the safety and endurance of policosanol (20 mg/d), as well as its efficacy in healthy individuals. Two parallel groups in this randomized, double-blind, placebo-controlled human experiment received either a policosanol (20 mg/d) or a placebo for eight weeks. 80 people were randomly assigned, with a mean (SD) age (years) of 42.61 (13.51), a mean (SD) BMI (kg/m2) of 24.53 (3.57), a mean (SD) weight (kg) of 66.71 (14.30), and a mean (SD) height (cm) of 164.21. (7.99).

Results
At 8 weeks, when compared to the baseline group, the policosanol (20 mg/d) batch displayed considerably greater LDL-C (-4.87 ± 11.30 mg/dL; p = 0.014), total cholesterol (-6.82 ± 14.32 mg/dL; p = 0.007), triglyceride (-9.37 ± 19.27 mg/dL; p = 0.008), non HDL-C reductions (-10.32 ± 13.75 mg/dL; p = 0.0001), and significantly greater augmentation of HDL-C (3.50 ± 4.55 mg/dL; p = 0.010). Policosanol (20 mg/d) treatment also significantly reducing the serum levels of TC/HDL-C (p = 0.0001) and LDL-C/HDL-C (p = 0.0002), triglyceride/HDL-C (p = 0.001), and T-cholesterol-HDL-C/HDL-C (p = 0.0001) ratios.

Conclusion
In humans, policosanol delivery resulted in a lowering of LDL-C levels and an improvement in other lipid markers, demonstrating the product potential to regulate hypercholesterolemia.
