Objectives This study was designed to analyze the clinical studies on Mental retardation(MR) in traditional Chinese medicine(TCM). Methods For this study, we searched the clinical studies on MR, which had been published from 2003 to 2007, through web site CNKI(中國知識基礎設施工 http://www.cnki.net). There were 17 clinical studies and we focused on those studies. Results 1. In those Chinese studies, they used following words to describe Mental retardation; 小人弱智($xi\check{a}o\acute{e}rru\grave{o}zh\grave{i}$), 智能發育不全($zh\grave{i}n\acute{e}ngf\bar{a}y\grave{u}buqu\acute{a}n$), 智力低下($zh\grave{i}l\grave{i}d\bar{i}xi\grave{a}$), 精神發育遲滯($j\bar{i}ngsh\acute{e}f\bar{a}y\grave{u}ch\acute{i}zh\grave{i}$), 智能落后($zh\grave{i}n\acute{e}nglu\grave{o}h\grave{o}u$), 智能落后($zh\grave{i}n\acute{e}ngch\acute{i}hu\check{a}n$), 失天愚型患人($xi\bar{a}nti\bar{a}ny\acute{u}x\acute{i}nghu\grave{a}n'\acute{e}r$). 2. There were many kinds of TCM treatment methods for MR, such as herbal medicine, acupuncture, electroacupunture, acupoint injection, Chuna therapy, and special education. And those TCM treatments methods showed higher efficacies in the treatment of MR compared with Western medicine. 3. Mental retardation was related with the deficiency of heart, kidney, liver, spleen(心虛, 腎虛, 肝虛, 脾虛) and the pathological mechanism of Phlegm(絹) and Blood stasis(慫沂)in the studies about the Bian Zheng-the types of differential diagnosis- of MR. 4. Most of studies used Intelligence Quotient(IQ) to assess the efficacy of TCM treatment of MR. And the duration of treatment, the degree of illness, the age of patient, and the cause of illness affected the prognosis of MR. Conclusions These results suggest that traditional medicine could be one of the useful treatments on MR. And these results could be used in the clinical practices and studies on MR in Korea.

Objectives: This research aimed to investigate Chinese clinical studies on the treatment of central post-stroke pain (CPSP) and thalamic syndrome after stroke with traditional herbal medicine (THM). Methods: Randomized controlled trials verifying the effects of herbal medicine on treating CPSP and thalamic syndrome after stroke were included in the study. Electrical and hand search were conducted in the China National Knowledge Infrastructure (CNKI), National Discovery for Science Leaders (NDSL), Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (Oasis) for CPSP and thalamic syndrome after stroke. A literature search was performed in the Chinese and Korean databases for papers published from January 1, 2010 to October 1, 2018. The selected literature was assessed by Cochrane's risk of bias. Results: Twelve reports on randomized controlled trials met the inclusion criteria from the 227 identified reports. Effective rate, comparison of visual analogy scale, present pain intensity, pain grading index, recurrence rate, follow-up, and a 36-item short form survey instrument were used to evaluate the treatments. The effective rate of the treatment group was significantly higher than that of the control group in all papers. Side effects occurred less frequently in the treatment group than in the western medicine control group. Conclusions: The treatment of CPSP and thalamic syndrome after stroke with THM was shown to be highly effective. Additional well-designed clinical trials are needed. This study can be used as a basis for further research on the treatment of CPSP and thalamic syndrome after stroke.

Objectives: The purpose of this study is to review clinical studies of Traditional Chinese medicine (TCM) on Genito-Pelvic Pain/Penetration Disorder (GPPPD) in women. Methods: Key words "Dyspareunia", "Vaginismus" were searched on Chinese National Knowledge Infrastructure Database (CNKI) on April 21th 2019. Results: 2 case reports and 7 clinical trials were collected in accordance with the selection and exclusion criteria. Among the 7 trials, 4 were controlled trials, and 3 were single-arm trials. The types of intervention were herb medication in 8 studies, and compound TCM treatment including acupuncture, moxibustion, and cupping therapy in 1 study. All 4 controlled trials were about dyspareunia and conducted by herbal medicine of TCM. The study results and methods of intervention were analyzed. Conclusions: 2 case reports described the effectiveness of compound TCM treatments (acupuncture, moxibustion, cupping therapy) and herb medicine in dyspareunia. In 4 controlled trials, 2 trials described the effectiveness of herb medicine (oral or vaginal agent) compared to western treatment in dyspareunia, and other 2 trials described no effectiveness of herbal enema compared to danazol. In 3 single-arm trials, 1 trial of dyspareunia and 2 trials of vaginismus described the effectiveness of herb medicine. All the 9 selected studies reported improved or disappeared symptoms of GPPPD, or high effective rate after TCM treatment. There was limitation that the selected studies were retrieved from only one site of CNKI, and generalized results could not be derived, further studies should be carried out. Additional well-designed clinical studies on GPPPD in women are needed in Korea.

Blended Learning is one of the most popular methods in education for encouraging active learning and improving student learning effectiveness, and it is regarded as one of the most effective methods for universities to attract students. Based on the cultural dimension theory, this paper examined blended learning research trends in both South Korea and China, which are culturally similar but also differ. The research methods include keyword analysis and visualization. Academic papers on blended learning indexed by WoS, KISS, and CNKI from 1990 to June 2022 were collected and analyzed. According to the findings, since the outbreak of COVID-19, the common research topic of blended learning has been subdivided by forming clusters in various research fields. Korea and China exhibit similarities to global research trends while exhibiting differences based on cultural background. The cultural dimension theory-based analysis reveals a common pattern that is especially long-term oriented. The findings can suggest significant implications for designing what role national culture plays in forming patterns of education and research and for developing blended learning with effective impacts in a multicultural educational environment.

Objectives: The purpose of this study was to evaluate the effects of shenfu injection on myocardial protective effects after mitral valve replacement surgery. Methods: We searched four international databases (PUBMED, Embase, Web of Science and CNKI) and three domestic electronic databases (OASIS, RISS and NDSL) for relevant studies. We used following keywords 'shenfu', 'valve replacement', 'mitral valve' at PUBMED, Embase and Web of Science; '二尖瓣', '参附注射液', '瓣膜' at CNKI and '이첨판', '판막', '삼부' at domestic databases. The search range included randomized controlled trials. When appropriate, meta-analyses were performed. Results: Seven randomized controlled trials were selected. All studies used Shenfu injection after mitral valve replacement surgery. We analyzed myocardial damage, cardiac function, patients' recovery rate, with various evaluation indicators. We also used meta-analysis for CK-MB, cTnI, MDA and voluntary recovery of heartbeat. CK-MB was analyzed in two subgroups: 8 hours and 24 hours after surgery. Std was -2.34(95% CI -4.10, -0.58) for 8 hours and -1.95(95% CI -4.79 to 0.88) for 24 hours. 8 hours showed statistically significant difference. cTnI appeared significant decrease with Std of -2.13(95% CI -2.60, -1.66). MDA showed significant decrease with Std of -0.95(95% CI -1.43 to -0.47). Voluntary recovery of heartbeat significantly increased with the odd ratio of 4.34(95% CI 1.76, 10.70). Conclusions: We suggest that Shenfu injection after Mitral valve replacement surgery may have significant myocardial protective effects in terms of reducing myocardial damages, reactive oxygen species, increasing cardiac function and patients' recovery after surgery. However, the evidence is limited, further research is required.

Objectives: This review investigated the research on warm herbal foot bath therapy (WHFT) for insomnia. Methods: A search was conducted on the China National Knowledge Infrastructure (CNKI) database to collect relevant studies published up to August 29, 2023. Randomized controlled trials (RCTs) comparing WHFT and sleeping pills in patients with insomnia were included. The methodological quality of the included studies was assessed using the Cochrane risk-of-bias assessment tool. The results of the meta-analysis were presented as risk ratios (RRs) or mean differences (MDs) and their 95% confidence intervals (CIs). Results: A total of 11 RCTs were included. WHFT as monotherapy resulted in a significantly higher total effective rate (TER) (RR, 1.25; 95% CI, 1.15 to 1.36; I²=25%) and an improved Pittsburgh Sleep Quality Index (PSQI) global sore (MD, -3.10; 95% CI, -4.24 to -1.95; I²=73%) compared to benzodiazepines. Additionally, WHFT as a combined therapy with benzodiazepines resulted in a significantly higher TER (RR, 1.15; 95% CI, 1.04 to 1.27; I²=0%) and an improved PSQI global score (MD, -2.23; 95% CI, -4.09 to -0.38; I²=80%) compared to benzodiazepines alone. In network analysis visualizing the components of HWFT, four clusters were discovered, and Polygoni Multiflori Ramuls and Ziziphi Spinosae Semen were the key herbs used in WHFT. Overall, the methodological quality of the included studies was poor. Conclusions: There was limited evidence that WHFT as a monotherapy or combined therapy was effective in improving insomnia. The findings can be used as basic data for future WHFT research in South Korea.
