Objectives: This study was aimed to evaluate the hemodynamic feasibility using pulse parameters as a way to establish safe dose guidelines for Chunwangbosim-dan, and to provide a foundation for developing evidence-based guidelines for clinical use. Methods: Forty-one volunteers were recruited to participate in a study examining the changes in pulse wave characteristics following the ingestion of Chunwangbosim-dan, over a period of 2 weeks, and pulse wave measurements were taken before and after the administration. Pulse wave parameters were measured in this study using a 3-dimensional radial pulse tonometry device(DMP-Lifeplus). In addition, questionnaire, blood pressure, temperature, and body composition were also measured as secondary measures. Results: Fifteen minutes after administration of Chunwangbosim-dan, the non-adverse event group(non-AE) exhibited a statistically significant increase in several power and pressure-related parameters, including h1, h3, h4, h5, SA, PA and PW, while the adverse event group(AE) showed a trend of decreasing stroke volume and increasing Systemic Vascular Resistance Index(SVRI) and applied pressure. After 2 weeks of administration, non-adverse event group(non-AE) exhibited significant changes in standard deviation of pulse rate and HRV_LH ratio. Notably, there are significant differences between AE group and non-AE group in h4/h1, w/t, applied pressure, SV and pulse rate. Conclusion: These findings suggest that pulse parameters may be a useful way to establish safe dosing guidelines for Chunwangbosim-dan. Further research is needed to confirm these results and to develop evidence-based guidelines for clinical use.

Objectives: Gyeongokgo is a traditional medicine typically used for individuals with wasting disorders and decreased immunity. Carop is well-known for its exceptional antioxidant effects. The objective of this study was to determine whether the antioxidant and anti-inflammatory properties of Gyeongokgo may be enhanced by the addition of carob. Methods: Cytotoxicity was confirmed using an MTT assay. Free radical scavenging activity ability was evaluated using DPPH assay. The amount of produced nitrogen oxide, TNF-α, and IL-6 were measured using an ELISA reader. Results: The Gyeongokgo with carob showed no cytotoxicity and a synergistic effect on antioxidant activity, when compared with the Gyeongokgo without carob. In addition, the inhibitory effect on nitric oxide production was higher for the Gyeongokgo with carob when compared with the Gyeongokgo without carob. The anti-inflammatory response of the Gyeongokgo with carob was possibly through the suppression of the production of TNF-α and IL-6. Conclusion: The addition of carob to Gyeongokgo may be an effective measure to enhance the antioxidant and anti-inflammatory effects.

Objectives: Psoriasis is a common chronic inflammatory skin disease characterized by keratinocyte hyperproliferation and an excessive inflammatory response. Agents that can attenuate keratinocyte hyperproliferation and excessive inflammatory responses are considered potentially useful for the treatment of psoriasis. Daehwangmokdanpitang (DHMDPT) exhibits a broad range of bioactivities, including anti-proliferative and anti-inflammatory effects. This study aims to evaluate the anti-psoriatic potential of DHMDPT in vitro. Methods: HaCaT keratinocytes were stimulated with a mixture of IL-17A, IL-22, oncostatin M, IL-1α, and TNF-α (M5) to establish an in vitro psoriatic keratinocyte model. Cell viability was measured using the MTT assay. Quantitative real-time PCR (qRT-PCR) was performed to measure the mRNA levels of the hyperproliferative marker gene keratin 6 (KRT6) and inflammatory factors such as IL-6, TNF-α, and IL-23A. Additionally, chemokines including CCL5, CCL2, CCL20, and CXCL1 were measured by qRT-PCR. Results: DHMDPT attenuated M5-induced hyperproliferation, as indicated by a reduction in KRT6 expression in HaCaT keratinocytes. M5 stimulation significantly upregulated the mRNA levels of IL-6, TNF-α, and IL-23A. However, DHMDPT treatment attenuated the upregulation of IL-6 but not TNF-α or IL-23A. Additionally, DHMDPT inhibited the expression of CCL5, CCL2, and CXCL1, but not CCL20. Conclusion: DHMDPT effectively attenuated the M5-induced proliferation and inflammatory response in HaCaT keratinocytes. Therefore, DHMDPT could be an attractive candidate for future development as an anti-psoriatic agent.

Objectives: This study aims to evaluate the clinical validity of the system by conducting a clinical study to assess the diagnostic agreement between the system and Korean medical doctors. Methods: This study was conducted from September 7, 2023, to December 7, 2023, across five Korean medicine institutions, involving 100 adult participants aged 20-64 who consented to participate. Participants first entered their symptoms into a web-based program, which utilized an AI-based algorithm to diagnose 36 types of pattern differentiation. Subsequently, Korean medical doctors conducted face-to-face diagnoses using the same 36 types. The diagnostic agreement between the system and the doctors' diagnoses was analyzed using descriptive statistical analysis, and the results were expressed as a percentage agreement. Results: Analysis of the diagnostic data from 100 participants revealed that the web-based diagnosis support system identified an average of 7.76±0.79 patterns per patient, while Korean medical doctors identified an average of 7.99±0.10 patterns per patient. The diagnostic agreement between the system and the doctors showed an average of 7.08±1.08 patterns per patient, with an overall diagnostic agreement rate of 88.57±13.31%. Conclusion: This study developed a web-based diagnosis support system for traditional Korean medicine and evaluated its clinical validity by assessing diagnostic agreement. Comparing the diagnoses of the system with those of Korean medical doctors for 100 patients, the system showed an approximately 89% agreement rate with the clinical diagnoses. The system holds potential for aiding Korean medical doctors in pattern differentiation diagnosis in clinical practice.
