Objectives Tongue diagnosis is an important diagnostic method in traditional Eastern medicine, and it has a high potential to be used in the future healthcare because of easy, quick, and non-contact measuring features. Recently, research and development efforts on computerized tongue diagnosis systems (CTDS) have been active that led to the technical advancements in the field of photographing techniques, image extraction and classification algorithms. In this study, we analyzed the trends in the CTDS patents. Using the WIPS search engine (www.wipsglobal.com), quantitative and qualitative patent analyses were performed through Korea, China, Japan, U.S.A and Europe. Methods For a systematic search and data analysis, we defined patent categories based on the application area and technical details. By applying thus-obtained categorical key words, we obtained 360 relevant patents on photographing techniques, image extraction and classification algorithms for the purpose of diagnosis or security. Results As a result, companies related to image acquisition, medical imaging and mobile devices and research groups of universities in East Asia were major patent applicants. In all the five countries, the number of patents have been increasing since 1980. In particular, technology related to color correction and image segmentation were most actively patented categories, and expected to continue a high application rate.

Objectives : In recent years, the Chinese Government has been providing full support aimed at promoting the excellence of Chinese culture, including Traditional Chinese Medicine (TCM), to the world after recognizing Chinese culture and medicine as elements that can generate national wealth. Methods : In investigating China's awareness of the issues surrounding the intellectual property rights of TCM, as well as its implementation of protective measures, this study analyzed the law and platform policies of the Chinese Government, as well as the designation status of China's intangible cultural heritages and the recent research trend in the TCM field. Results : First, China is taking various protective measures based on laws and institutional devices, including the Patent Act. Second, China is protecting the intellectual property rights of traditional Chinese medicines by registering them as Chinese intangible cultural heritages or UNESCO world heritages. Third, China is seeking to promote TCM throughout the wider world through various research and academic conferences, and by strengthening ties between nations. Conclusions : With the adoption of the international regimes of the WIPO and CBD, and particularly the Nagoya Protocol in 2010, China is seeking to implement measures aimed at maximizing the national interest based on the intellectual property rights of TCM. China began to implement a system of protection of medicinal resources and the related traditional knowledge after recognizing the potential crisis that could occur if Chinese medicine-related patents were taken over by foreign countries. As such, the system now takes various forms.

Objectives : This study collected and analyzed information related to preventive formulas from continuously published and revised COVID-19 treatment guidelines in various regions of China. Methods : We collected treatment guidelines published in different regions of China and categorized formulas for prevention and medical observation period listed in them according to the editions. The categorized preventive formulas were compared by type and target group. Results : Herbal medicines used for prevention included formulas derived from Korean medical classics, such as Okbyeongpungsan(玉屏風散) and Eunkyosan(銀翹散). The newly composed formulas, totaling over 100, were created by adding, subtracting, and combining formulas such as Sang-gukeum(桑菊飮), Eunkyosan(銀翹散), Sasammaekmundongtang(沙參麥門冬湯), Okbyeongpungsan(玉屏風散), Gwakhyangjeong-gisan(藿香正氣散), and Soshihotang(小柴胡湯). Patent medicines including Huoxiangzhengqi capsule(藿香正氣膠囊), Lianhuaqingwen capsule(連花淸瘟膠囊), Shufengjiedu capsule(疏風解毒膠囊), and Jinhuaqinggan granule(金花淸感顆粒) were frequently used, mainly targeting close contacts. These medicines were used differently depending on the specific population group, such as the general population, the elderly, children, pregnant women, and patients with underlying diseases, and were also applied differently according to the individual's constitution. Conclusion : We were able to identify various background factors contained in the guidelines for the use of preventive formulas presented by TCM group, and understand the social conditions that enabled the group to provide such guidelines. Through this, thorough preparation should be made so that the Korean Medicine can actively respond to another future pandemic.

As social interest in acne treatment has grown, various external preparations have been developed and studied. So, we investigated the external prescription which can treat acne in medical classics, then reviewed and divided it by dynasty. The data for analysis of Herbal formula was taken from 'medicine Dictionary of traditional Chinese medicine prescriptions(中醫方劑大辭典)'. 31 external medicines were searched, 3 were before song(宋) dynasty, 11 were Song(宋) dynasty, 11 were Yuan(元) dynasty, 7 were Ming(明) dynasty and 7 were Qing(淸) dynasty. The recipe and usage were only making them pill(丸) and paste(膏) using grinded medicinal herbs, then rubbing to face. As the age developed, unique manufacturing process(i.e fermentation method), and usage(i.e time-based usage, herbal medicine extracts for wash) were proposed. The external application with oriental medicine for acne used with Angelicae Gahuricae Radix(n=12), Bletillae Rhizoma(n=8), Syzygii Flos, Saposhnikoviae Radix(n=7) and so on. In particular, Bletillae Rhizoma was searched with high frequency in this study, but it was not included or studied in patent composition. The results of this study will provide basic data for future experiments and clinical studies.

Objectives : The purpose of this study is to assess the effect of using Boyanghwano-tang(BYHWT) for diabetic retinopathy. Methods : We searched randomized controlled trials(RCTs) that used BYHWT for diabetic retinopathy in 10 databases(RISS, KISS, ScienceON, KCI, OASIS, DBpia, CNKI, Wanfang Database, PubMed, Cochrane Library) on August 12, 2023. Outcome measurements included total effective rate(TER) and visual acuity as the primary outcome measurements, and the secondary outcome measurements included fasting blood glucose(FBG), 2hPG, HbA1c, ET-1, NO, etc. The indicator of stability included adverse reactions. A meta-analysis was conducted according to TER, visual acuity, FBG. Results : A total of 8 randomized control trials were selected. The treatment group which used BYHWT showed significant improvement effects in TER and visual acuity compared to the control group which used western medicine or chinese patent medicine alone. TER: (RR: 1.22, CI 1.14 to 1.31, P=<0.00001), visual acuity: (RR: 2.06, CI 1.40 to 3.03, P=0.0002). Secondary outcome measurements including FBG also showed improvement in the treatment group compared to the control group. FBG: (MD: -0.15, CI -0.43 to 0.31, P=0.28). Adverse reactions were only mentioned in one study, which showed that no adverse reactions occurred in both the treatment and control groups. Conclusions : This study suggests that BYHWT is effective for diabetic retinopathy. However these findings should be interpreted cautiously due to the insufficient number of studies and unknown or high risk of bias in the included trials.
