Coronary microvascular disease (CMVD) is a high risk factor for many cardiovascular events. Due to the limited understanding of its pathophysiological mechanism, modern medicine still lacks therapeutic drugs for CMVD. Existing clinical studies have shown that traditional Chinese medicine (TCM) can effectively improve the clinical symptoms and quality of life of CMVD patients. ⋯ In the face of numerous oral CPMs for treatment of CMVD, how to choose a reasonable medication regimen is one of the important issues in clinic. Based on this, this paper reviewed the clinical efficacy and recommended level of 12 CPMs in the treatment of CMVD, which are recommended by expert consensus on diagnosis and treatment of coronary microvascular disease with integrated Chinese and Western medicine (WM). In addition, this study also systematically summarized the possible mechanisms of CPMs in the treatment of CMVD by protecting coronary microvascular endothelial cells, improving vascular endothelial function, inhibiting inflammation, reducing oxidative stress, promoting angiogenesis, and improving hemorheology, aiming to provide meaningful information for its clinical application.

Review
Regulatory mechanisms and clinical applications of tumor-driven exosomal circRNAs in cancers.
Malignant tumors seriously affect people's survival and prognosis. Exosomes, as vesicle structures widely existing in human tissues and body fluids, are involved in cell-to-cell transmission. ⋯ Tumor-driven exosomal circRNAs are often involved in tumorigenesis and development including the proliferation, invasion, migration and chemo-or-radiotherapy sensitivity of tumor cell by multiple regulatory mechanisms. In this review, we will elaborate the roles and functions of tumor-driven exosomal circRNAs in cancers which may be used as potential cancer biomarkers and novel therapeutic targets.

Biliary tract cancers (BTCs) are a heterogenous group of malignancies arising from the epithelial cells of the biliary tree and the gallbladder. They are often locally advanced or already metastatic at the time of the diagnosis and therefore prognosis remains dismal. Unfortunately, the management of BTCs has been limited by resistance and consequent low response rate to cytotoxic systemic therapy. ⋯ Although there are still few data available, ctDNA analysis in BTC is fast, non-invasive, and could also represent a way to diagnose BTC earlier and monitor tumor response to chemotherapy. The prognostic capabilities of soluble factors in BTC are not yet precisely determined and more studies are needed. In this review, we will discuss the different approaches to immunotherapy and tumor circulating factors, the progress that has been made so far, and the possible future developments.

Comparative Study
Effect of the Brief Instructional Video Intervention on the Quality of Cardiopulmonary Resuscitation.
Background: Chest compressions are the basis of cardiopulmonary resuscitation (CPR), and high-quality chest compressions can improve survival rate in patients with out-of-hospital cardiac arrest. Although many efforts have been made to improve the quality of CPR in inexperienced adults, the results are still not high, especially during emergencies. The primary purpose of this study is to investigate whether a brief instructional chest compression-only CPR video could improve chest compression quality in inexperienced adults. ⋯ For phases 2 through 3, V-CPR and WV-CPR achieved significant differences in CCF, CCD, CCR, PCCR, and RPE (p < 0.01). There were significant differences (p < 0.05) in CCF, CCD, chest compression rebound rate, and RPE among the different administration stages of both WV-CPR and V-CPR. Conclusions: The results of this study revealed that a brief instructional chest compression-only CPR video could improve chest compression quality for inexperienced adults by reducing fatigue and CCR, and increasing CCF and PCCR.

Randomized Controlled Trial
A functional evaluation of anti-fatigue and exercise performance improvement following vitamin B complex supplementation in healthy humans, a randomized double-blind trial.
B vitamins play a crucial role in maintaining fundamental cellular functions and various essential metabolic pathways in the body. Although they do not directly provide energy, each B vitamin acts as a cofactor in energy metabolism processes. Based on the evidence presented above, we hypothesized that a 28-day supplementation of vitamin B would enhance physical performance and reduce physical fatigue. ⋯ In addition, the Ex PLUS® supplementation group presented significantly reduced blood lactate and blood ammonia concentrations during exercise and at rest after exercise compared with placebo (p < 0.05). In conclusion, 28 consecutive days of vitamin B complex (Ex PLUS®) supplementation significantly improved exercise endurance performance and reduced exercise fatigue biochemical metabolites in not athletes. In addition, it does not cause adverse effects in humans when taken at appropriate doses.
