Liposomes are attractive carriers for targeted and controlled drug delivery receiving increasing attention in cancer photothermal therapy. However, the field of creating near-infrared nanomaterial-liposome hybrid nanocarriers (NIRN-Lips) is relatively little understood. The hybrid nanocarriers combine the dual superiority of nanomaterials and liposomes, with more stable particles, enhanced photoluminescence, higher tumor permeability, better tumor-targeted drug delivery, stimulus-responsive drug release, and thus exhibiting better anti-tumor efficacy. Herein, this review covers the liposomes supported various types of near-infrared nanomaterials, including gold-based nanomaterials, carbon-based nanomaterials, and semiconductor quantum dots. Specifically, the NIRN-Lips are described in terms of their feature, synthesis, and drug-release mechanism. The design considerations of NIRN-Lips are highlighted. Further, we briefly introduced the photothermal conversion mechanism of NIRNs and the cell death mechanism induced by photothermal therapy. Subsequently, we provided a brief conclusion of NIRNs-Lips applied in cancer photothermal therapy. Finally, we discussed a synopsis of associated challenges and future perspectives for the applications of NIRN-Lips in cancer photothermal therapy.

Metabolic dysfunction-associated steatohepatitis (MASH) is a large group of metabolic diseases that are hazardous to human health. Endothelial-to-mesenchymal transition (EndMT) mediated myofibroblast activation is an important factor that aggravates the development of liver fibrosis during MASH. However, the limited understanding of the underlying molecular mechanisms that drive EndMT in MASH has hindered the development of molecularly targeted therapies specifically targeting this pathological process. We employed wild-type and ifn-γ-deficient mice, MASH models were induced repeated CCl4 injections and a high-fat diet to verify the significance of IFN-γ role in vivo and its impact in EndMT. Male mice models of MASH were used to further analyze the effect of Scutellarin@BSA on the improvement of liver fibrosis during MASH in vivo and HUVECs were used to assess IFN-γ effect on EndMT and its interaction with JAK signaling pathway in vitro. The results showed that IFN-γ is revealed as a key regulator of EndMT during MASH, as evidenced by the significantly lower levels of EndMT and reduced pathological damage in the livers of ifn-γ knockout mice. Furthermore, our research has led to the development of Scutellarin@BSA therapy, which targets and mitigates IFN-γ-driven EndMT, which showed excellent therapeutic effects on EndMT and liver fibrosis in vivo and in vitro during MASH. Mechanistically, IFN-γ can directly bind to the JAK protein and activate downstream STAT1 transcription factors, exerting transcriptional activity and further driving the expression of EndMT-associated proteins. Notably, Scutellarin@BSA treatment effectively diminishes the hallmarks of liver fibrosis by modulating the canonical JAK/STAT1 signaling pathway. IFN-γ was identified as a key regulator of EndMT, and Scutellarin@BSA, as an emerging treatment, has been found to effectively inhibit EndMT by directly targeting the regulatory influence of the IFN-γ signaling. This result demonstrates significant therapeutic efficacy in alleviating hepatic fibrosis during MASH, highlighting its great potential as an innovative liver fibrosis treatment.

Background: Parkinson's disease (PD) and irritable bowel syndrome (IBS) are respectively one of the most common neurodegenerative diseases and functional bowel diseases in the world. Recent studies suggest that patients with IBS seem to have a higher risk of PD, which conflicts with the result of previous meta-analysis. Therefore, the purpose of this systematic review is to evaluate all available evidence, in order to clarify the association between PD and IBS.Methods: Two reviewers independently searched the PubMed, Embase, Web of Science, and Cochrane library on April 25, 2021 to identify all records that explore the association between IBS and PD. All reports that clearly define PD and IBS and analyze the relationship between the two were included. The Newcastle-Ottawa scale was used to assess the risk of bias of included studies.Results: Five studies from four articles involving 2,044,110 subjects were included in this analysis. The pooled results demonstrated a significant association between PD and IBS (1.48; 95% CI: 1.35–1.62, P < 0.001), with subtle heterogeneity (I² = 0.0%, p = 0.585). The association was observed across genders and increased with age. However, the available evidence cannot allow a reliable analysis of the causal relationship between IBS and PD.Conclusion: This study demonstrates a higher risk of PD among subjects with IBS. Future studies are required to further clarify the causation and underlying mechanism of the association.

Malignant melanoma is the most fatal form of skin cancer worldwide, and earlier diagnosis and more effective therapies are required to improve prognosis. As a possible solution, near-infrared fluorescent heptamethine cyanine dyes have been shown to be useful for tumor diagnosis and treatment. Here, we synthesized a novel theranostic agent, IR-817, a multifunctional bioactive small-molecule that has near-infrared emission, targets mitochondria in cancer cells, and has selective anti-cancer effects. In in vitro experiments, IR-817 preferentially accumulated in melanoma cells through organic anion transporting polypeptide transporters but also selectively inhibited the growth of tumor cells by inducing mitochondrial-dependent intrinsic apoptosis. Mechanistically, IR-817 caused G0/G1 cell cycle arrest by targeting the E2F/Cyclin/CDK pathway. Finally, IR-817 significantly suppressed the growth of xenograft tumors in zebrafish and mice. Immunohistochemical staining and hematoxylin and eosin staining revealed that IR-817 induced apoptosis and inhibited tumor cell proliferation without notable side effects. Therefore, mitochondrial-targeting theranostic agent IR-817 may be promising for accurate tumor diagnosis, real-time monitoring, and safe anti-cancer treatments.

Objective: Cardiac arrhythmia remains a major public health problem worldwide. Combinations of traditional medicine (TM) and conventional medicine (CM) have been used for arrhythmia treatment, yet the effectiveness and safety of many TM preparations can be controversial. We analyzed the safety and effectiveness of Zhigancao decoction (ZGCD) combined with metoprolol for arrhythmia treatment.Methods: Systematic searches for randomized clinical trials (RCTs) were conducted in eight databases (January 2010–September 2020) without language restrictions. According to the Cochrane system evaluation method, the overall effectiveness and safety were evaluated by meta-analysis using Review Manager software (version 5.3), and publication bias was qualitatively analyzed using STATA 12.0.Results: A total of 39 RCTs were incorporated, including 4,260 patients with arrhythmia, with 2,133 patients in the experimental group (ZGCD + metoprolol, ZGCD + BB) and 2,127 patients in the control group (metoprolol only, BB). Meta-analysis revealed that compared with BB, ZGCD + BB could significantly increase the total efficacy (OR = 4.74, 95% CI: 3.78–5.94, P < 0.01) and lower the incidences of arrhythmia (MD = −3.39, 95% CI: −4.09 to −2.68, P < 0.01). Moreover, mean HR reductions were reported in patients receiving ZGCD + BB the ZGCD + BB group (MD = −8.48, 95% CI: −10.98 to −5.97, P < 0.01) and a decrease in TCM symptoms were reported also (MD = −2.92, 95% CI: −3.08 to −2.76, P < 0.01). The incidence of adverse events was lower in patients treated with ZGCD + BB (RR = 0.36, 95% CI: 0.26–0.51, P < 0.01). These results appeared consistent across common arrhythmias. Nevertheless, the majority of included studies were unable to be formally assessed for bias, and funnel-plot analysis implied a moderate risk of publication bias.Conclusion: ZGCD + BB appeared to demonstrate good efficacy and fewer adverse reactions compared to BB in the treatment of arrhythmia, and this may represent a useful complementary therapy. However, our findings must be cautiously evaluated because of the small sample size and low quality of the clinic trials cited in the review. Rigorous and large-scale RCTs are warranted in the future to confirm these results.Systematic Review Registration: https://inplasy.com/inplasy-2021-10-0045/.

Hemorrhagic wound management in severe trauma patients remains a vital clinical problem because of uncontrolled bleeding and inflammatory responses. Charcoal drugs have shown great potential for facilitating hemostasis and wound repair for more than two thousand years. Nevertheless, studies on the inherent biological activities of charcoal drugs and their corresponding pharmacological effects are far from satisfactory. Herein, a novel carbon dot prepared from charred Mume Fructus (CMF-CDs) for enhancing hemorrhagic wound healing was reported for the first time. Surprisingly, the as-prepared CMF-CDs showed good biocompatibility, reactive oxygen species scavenging ability and protection of human cells from oxidative damage. Inspired by this, we confirmed that CMF-CDs enhanced hemorrhagic wound healing by facilitating hemostasis, M2-type macrophage polarization, angiogenesis, collagen deposition and tissue regeneration. Proteomic results further revealed that the CMF-CDs reshaped the inflammatory microenvironment of the wound by reducing excessive ROS produced by tissue oxidative phosphorylation and the tricarboxylic acid cycle metabolic pathway. Ultimately, the discovery of CMF-CDs holds enormous promise for managing severe traumatic wounds and provides theoretical and material insights into charcoal drug-mediated hemostasis applications.
