However, the relative advantages and disadvantages of TCM external therapies and their mechanisms of action have not yet been confirmed in evidence-based medicine. We used network meta-analysis to rank the effectiveness and safety of TCM external therapies, screen the optimal TCM external therapies. TCM external therapies for KOA published before October 2024 were comprehensively retrieved from eight electronic databases. Using the Cochrane Reviewers' Handbook, two independent reviewers performed study selection, data extraction, and bias assessment of the included randomized controlled trials (RCTs). Data analysis was conducted using Stata 16.0 and RevMan 5.4 software. A total of 68 RCTs were identified, including 6571 participants, involving 11 interventions, 4.41% of which showed a high risk of bias. The results of the network meta-analysis revealed that in terms of improving Visual Analog Scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) function scores, each external therapy was better than conventional medicine. Electroacupuncture may be the most effective intervention in improving the VAS score and TNF-α level. Moxibustion resulted in the greatest improvement in WOMAC function and IL-6 levels. The most effective interventions for reducing WOMAC pain scores were the manual needle knife, followed by electroacupuncture and Tuina therapy (SUCRA = 82.9%, 79.0%, and 71.4%, respectively). Warming acupuncture dominantly increased Lysholm scores. The safety results showed that the three safest interventions were the sham intervention, Tuina therapy, and moxibustion (SUCRA = 90.6%, 83.1%, and 68.8%, respectively). Silver needle had the best comprehensive effect. Electroacupuncture has the best effect on improving pain symptoms, and moxibustion can be prioritized when functional limitations are the main symptoms.

It is caused by a thrombotic occlusion of coronary vessel/s that leads to cardiomyocyte death. As a response, inflammatory and fibrotic responses are initiated to replace the necrotic tissue and remodel the heart. However, in most cases, these responses are excessively activated, which accentuates the injury and causes adverse cardiac remodeling, often leading to heart failure. This is highly attributed to the dysregulated repair mechanism brought by reduced regenerative capacity of the adult heart, chronic inflammation, and other patient factors, such as comorbidities, diet, and lifestyle. Because of the negative consequences of excessive inflammation and fibrosis in post-MI responses, inhibiting factors associated with these processes are one of the major approaches in MI management. Several therapies have been developed to broadly and/or selectively inhibit inflammation- and fibrosis-associated proteins over the past decades and have shown promise in addressing post-MI complications. However, challenges (<i>e.g.</i>, off-targets, problems with drug delivery, dosage, route, and cost) and efficacy of these interventions in the clinical setting remain. Hence, alternative approaches to optimally alleviate these post-MI processes are still much needed. In this review, we discuss the possible use of plasmapheresis, a technique that involves extracorporeal replacement of blood plasma, as a treatment for MI.

Besides, FBXW5 inhibition significantly decreased cell viability by 49.05% in MDA-MB-231 cells and 62.30% in MCF-7 cells. FBXW5 inhibition significantly inhibited cell proliferation by 66% in MDA-MB-231 cells and 74% in MCF-7 cells.
