Treatment of vitiligo with 308-nm light emitting diode: Our experience from a two-year follow-up of Chinese patients.

BACKGROUND: A light emitting diode (LED), with a wavelength of 308 nm, has been utilized in the dermatologic treatment of vitiligo. OBJECTIVES: We investigated the efficacy and safety of 308-nm LED for use in the treatment of vitiligo. METHODS: We conducted a retrospective study of 70 stable-stage vitiligo patients (with a total of 99 lesions) who received 308-nm LED treatment at the Institute of Dermatology, Chinese Academy of Medical Sciences and Peking Union Medical College from June 2018 to June 2020. Treatment efficacy was evaluated after 8 treatment sessions, 16 treatment sessions, and the final treatment session, to estimate the percentage of re-pigmentation in the treated area. The Kruskal-Wallis test was used for data analysis. RESULTS: Based on the final treatment session analysis of all 99 lesions, 0 lesions showed no response, 21 lesions showed poor response, 29 lesions showed moderate response, 23 lesions showed good response, and 26 lesions showed excellent response. The efficacy rate was 49.49%, and there was a significant correlation between the six distinct anatomical regions treated and re-pigmentation grade (χ2  = 13.419, p = .009). Among these regions, facial lesions showed the best response to treatment, while the hands and feet lesions showed the poorest response. CONCLUSIONS: The clinical efficacy of 308-nm LED treatment is limited based on the treatment area. It demonstrated significant practical application in the treatment of vitiligo.

Efficacy and safety of Chinese herbal medicine Wen Xin granules for the treatment of unstable angina pectoris with Yang deficiency and blood stasis syndrome: study protocol for a randomized controlled trial.

INTRODUCTION: Unstable angina pectoris (UAP) is the common type of coronary heart disease with the risk of developing into acute myocardial infarction (AMI). Currently, there are still numerous patients suffering from recurrent angina after revascularization or conventional medication due to the microvascular lesions, endothelial dysfunction, chronic inflammation, in-stent restenosis, and other factors. As an important part of China's medical and health care system, traditional Chinese medicine (TCM) has rich clinical experience in the treatment of UAP. According to the theory of TCM, Yang deficiency and blood stasis syndrome is a common type of UAP. Wen Xin decoction, as a type of Chinese herbal medicine, has been used in the clinic for years and shown great efficacy in the treatment of UAP with Yang deficiency and blood stasis syndrome. This study aims to evaluate the efficacy and safety of Wen Xin granular in patients with UAP. METHODS AND ANALYSIS: This is a double-blinded, randomized, placebo-controlled clinical trial. A total of 502 participants will be randomly allocated to the intervention group and the placebo group. Based on conventional medication, the intervention group will be treated with Wen Xin granular and the placebo group will be treated with Wen Xin granular placebo. The primary outcomes are major adverse cardiovascular events (MACE). Assessments will be performed 1 year after the treatment. The secondary outcomes include TCM symptom scale score, Seattle angina questionnaire, and thromboelastography. Assessments will be performed at baseline (before randomization) and 4 and 8 weeks after randomization. DISCUSSION: This trial will provide high-quality data on the benefits and risks of Wen Xin granular in patients with UAP. TRIAL REGISTRATION: ClinicalTrials.gov NCT04661709 .

Advances in Research on the circRNA-miRNA-mRNA Network in Coronary Heart Disease Treated with Traditional Chinese Medicine.

There has been an increase in morbidity and mortality related to coronary heart disease (CHD) in China in recent years. Numerous clinical experiences and studies have shown that traditional Chinese medicine (TCM) plays an important role in the prevention, treatment, and prognosis of CHD. However, the mechanism of TCM in the treatment of CHD has not yet been elucidated. The circRNA-miRNA-mRNA network consists of miRNA that is competitively bound by circRNA, and miRNA regulates the transcription level of mRNA. Through literature review, we found that the circRNA-miRNA-mRNA network acts to contribute to certain effects to CHD such as myocardial hypertrophy, myocardial fibrosis, and heart failure. TCM contains constituents that act against CHD by antiatherosclerosis and apoptosis inhibition action, cardiac and cardiomyocyte protection, and these components also promote cell growth and protection of the vascular system by regulating miRNAs. Therefore, we consider that the circRNA-miRNA-mRNA network may be a new regulatory mechanism for the effective treatment of CHD by TCM.

Efficacy and safety of the Shexiang Baoxin Pill for the treatment of coronary artery disease not amenable to revascularisation: study protocol for a randomised, placebo-controlled, double-blinded trial.

INTRODUCTION: Coronary artery disease (CAD) not amenable to revascularisation indicates that the coronary arteries have severe diffuse lesions or calcifications, or that CAD is complicated with severe multiple-organ disease. Currently, Western medicines available for the treatment of CAD not amenable to revascularisation are limited. Shexiang Baoxin Pill (SBP), a type of Chinese patent medicine, has been widely used to treat CAD in China for many years. Previous studies have shown that long-term administration of SBP (1-2 pills three times daily, for at least 6 months) for treatment of CAD is effective and safe, with a significant, long-term effect. This study aims to evaluate the efficacy and safety of SBP in patients with CAD not amenable to revascularisation. METHODS AND ANALYSIS: This is a multicentre, randomised, double-blinded, placebo-controlled clinical trial. A total of 440 participants will be randomly allocated to two groups: the intervention group and the placebo group. Based on conventional treatment with Western medicine, the intervention group will be treated with SBP and the placebo group will be treated with SBP placebo. The primary outcomes include major adverse cardiovascular events (including angina, acute myocardial infarction, pulmonary embolism and aortic dissection). The secondary outcomes include C reactive protein, B-type natriuretic peptide, ECG, echocardiographic parameters (ejection fraction percentage and the E/A ratio) and hospital readmission rates due to CAD. Assessments will be performed at baseline (before randomisation) and at 24 weeks after randomisation. ETHICS AND DISSEMINATION: The protocol has been approved by the Research Ethics Committee of Guang'anmen Hospital, China Academy of Chinese Medical Sciences in Beijing, China (reference: 2016-129-KY-01). The results of this study will be published in a peer-reviewed journal and will be used as a basis for a multisite trial. TRIAL REGISTRATION NUMBER: NCT03072121; Pre-results.
