Background:Tripterygium wilfordii Hook F can cause adverse effects (AEs) in clinical application and may be harmful to human health. This study aim to summarize the AEs caused by T. wilfordii tgpolyglycoside (TWP), the most common preparation of T. wilfordii Hook F for clinical use. Methods: The Cochrane Library, EMBASE, PubMed, and Web of Science were searched to identify potential articles on this topic. All single-arm trials, controlled clinical trials, and randomized controlled trials were selected and summarized. Meta-regression was used to determine the sources of heterogeneity, and subgroups were used to identify factors leading to AEs. Results: Forty-six studies, comprising 25 randomized controlled trials, 13 controlled clinical trials, and 8 single-arm trials, were included in this meta-analysis, representing 2437 enrolled TWP-treated participants. Combined intervention, drug dosage, medication treatment, pharmaceutical manufacturers, and specific organ toxicity were identified as potential factors leading to TWP-induced AEs in this meta-analysis. In patients treated with TWP, the global incidence of AEs was 30.75% (95% confidence interval [21.18–40.33], I² = 97%), and that of severe grade AEs was 4.68% (95% confidence interval [0.00–12.72], I² = 53%). Organ-specific analyses indicated that TWP treatment elicited intestinal toxicity, reproductive toxicity, hepatotoxicity, nephrotoxicity, hematotoxicity, cutaneous toxicity, and other damages. The AEs analyzed in the subgroups of combined intervention, drug dosage, medication treatment, and pharmaceutical manufacturers were considered as primary outcomes, and organic-specific AEs were considered as secondary outcomes. Conclusions: The occurrence of TWP-induced AEs was systemic, organ-specific, and related to medication course, combined intervention, and drug dosage.

Background: RYR is a commonly used lipid-lowering dietary supplements in Asian and European countries, showing considerable benefits and low toxicity. This quantitative study aims to present high-quality evidence regarding the efficacy and safety of RYR in treating hyperlipidemia, in order to promote its clinical application.Methods: PubMed, embase, and Cochrane Central Register of Controlled Trials databases were systematically searched, and high-quality randomized controlled trials comparing RYR with non-RYR interventions were included. RevMan5.3 software was used to conduct the meta-analysis.Results: A total of 1,012 individuals participated in this study (481 in the experimental and 531 in the control group). In comparison to statins, RYR was more effective in lowering TG (MD, −19.90; 95% CI, −32.22 to −7.58; p = 0.002), comparable in lowering LDL-C and elevating HDL-C, and less effective in lowering TC (MD, 12.24; 95% CI, 2.19 to 22.29; p = 0.02). Compared with nutraceutical, RYR significantly reduced TC (MD, −17.80; 95% CI, −27.12 to −8.48; p = 0.0002) and LDL-C (MD, −14.40; 95% CI, −22.71 to −6.09; p = 0.0007), and elevated HDL-C (MD, 7.60; 95% CI, 4.33 to 10.87; p < 0.00001). Moreover, RYR effectively synergized nutraceutical to further reduce TC (MD, −31.10; 95% CI, −38.83 to −23.36; p < 0.00001), LDL-C (MD, −27.91; 95% CI, −36.58 to −19.24; p < 0.00001), and TG (MD, −26.32; 95% CI, −34.05 to −18.59; p < 0.00001). Additionally, RYR significantly reduced apoB (MD, −27.98; 95% CI, −35.51 to −20.45; p < 0.00001) and, whether alone or in combination, did not increase the risk of adverse events in patients with hyperlipidemia.Conclusion: RYR at 200–4800 mg daily appears to be a safe and effective treatment for hyperlipidemia, effectively regulating blood lipid levels with an exceptional impact on TG. Looking forward, high-quality clinical trials with longer observation periods are required to evaluate the efficacy and safety of RYR as a long-term medication.Systematic Review Registration: (https://www.crd.york.ac.uk/PROSPERO/), identifier (CRD4202128450).

Histologically, melanoma tissues had fewer positive cells percentage of pyroptosis-related genes (PRGs), GZMA, GSDMB, NLRP1, IL18, and CHMP4A in epidermal than in normal skin. Pyroptosis, a new frontier in cancer, affects the tumor microenvironment and tumor immunotherapy. Nevertheless, the role of pyroptosis remains controversial, which reason is partly due to the heterogeneity of the cellular composition in melanoma. In this study, we present a comprehensive analysis of the single-cell transcriptome landscape of pyroptosis in melanoma specimens. Our findings reveal dysregulation in the expression of PRGs, particularly in immune cells, such as CD8⁺ cells (representing CD8⁺ T cells) and CD57⁺ cells (representing NK cells). Additionally, the immunohistochemical and multiplex immunofluorescence staining experiments results further confirmed GZMA⁺ cells and GSDMB⁺ cells were predominantly expressed in immune cells, especially in CD8 ⁺ T cells and NK cells. Melanoma specimens secreted a minimal presence of GZMA⁺ merged CD8⁺ T cells (0.11%) and GSDMB⁺ merged CD57⁺ cells (0.08%), compared to the control groups exhibiting proportions of 4.02% and 0.62%, respectively. The aforementioned findings indicate that a reduced presence of immune cells within tumors may play a role in diminishing the ability of pyroptosis, consequently posing a potential risk to the anti-melanoma properties. To quantify clinical relevance, we constructed a prognostic risk model and an individualized nomogram (C-index=0.58, P = 0.002), suggesting a potential role of PRGs in malignant melanoma prevention. In conclusion, our integrated single-cell and bulk RNA-seq analysis identified immune cell clusters and immune gene modules with experiment validation, contributing to our better understanding of pyroptosis in melanoma.

In this quantitative study, we evaluated the effectiveness and safety of fire needle therapy for nodular prurigo. We systematically searched several databases, including EMBASE, PubMed, the Cochrane Library, the Web of Science, the China Network Knowledge Infrastructure, the Wanfang Data Knowledge Service Platform, and the China Science and Technology Journal Database, and retrieved randomized controlled trials comparing conventional therapies (control group) with fire needle therapy alone or in combination with conventional therapies. Revman 5.2 software was used to calculate risk ratios (RR) with 95% confidence intervals (CI). In total, 14 trials with 1176 participants were included. Our quantitative study showed that the effectiveness rate of fire needle therapy combined with conventional therapies was significantly higher than that of conventional therapies alone (fire needle + traditional Chinese medicine [TCM] vs. TCM: RR, 1.11; 95% CI, 1.04 to 1.18; fire needle + oral thalidomide + topical glucocorticoid [TGC] vs. thalidomide + TGC: RR, 1.41; 95% CI, 1.17 to 1.70; fire needle + TGC vs. TGC only: RR, 1.18; 95% CI, 1.07 to 1.31). Similar results were obtained for the Symptom Score Reducing Index (fire needle + TCM vs. TCM: mean difference [MD], −3.39; 95% CI: −5.39 to −1.39), visual analog scale scores for itching severity (fire needle vs. halometasone cream: MD, −0.93; 95% CI, −1.29 to −0.58; fire needle + TCM vs. TCM: MD, −1.18; 95% CI, −1.78 to −0.58), and Dermatology Life Quality Index (fire needle vs. halometasone cream: MD, −3.03; 95% CI, −3.43 to −2.63; fire needle + TCM vs. TCM: MD, −2.53; 95% CI, −3.12 to −1.94). Adverse event and recurrence rates were comparable between groups. Thus, fire needle therapy alone or combined with conventional treatments may be effective for nodular prurigo, without any additional side effects.
