Mitochondria, functioning not only as the central hub of cellular energy metabolism but also as semi-autonomous organelles, orchestrate cellular fate decisions through their endogenous mitochondrial DNA (mtDNA), which encodes core components of the electron transport chain. Emerging research has identified microRNAs localized within mitochondria, termed mitochondria-located microRNAs (mitomiRs). Recent studies have revealed that mitomiRs are transcribed from nuclear DNA (nDNA), processed and matured in the cytoplasm, and subsequently transported into mitochondria. mitomiRs regulate mtDNA through diverse mechanisms, including modulation of mtDNA expression at the translational level and direct binding to mtDNA to influence transcription. Aberrant expression of mitomiRs leads to mitochondrial dysfunction and contributes to the pathogenesis of metabolic diseases. Restoring mitomiR expression to physiological levels using mitomiRs mimics or inhibitors has been shown to improve mitochondrial function and alleviate related diseases. Consequently, the regulatory mechanisms of mitomiRs have become a major focus in mitochondrial research. Given that mitomiRs are located in mitochondria, targeted delivery strategies designed for mtDNA can be adapted for the delivery of mitomiRs mimics or inhibitors. However, numerous intracellular and extracellular barriers remain, highlighting the need for more precise and efficient delivery systems in the future. The regulation of mtDNA expression mediated by mitomiRs not only expands our understanding of miRNA functions in post-transcriptional gene regulation but also provides promising molecular targets for the treatment of mitochondrial-related diseases. This review systematically summarizes recent research progress on mitomiRs in regulating mtDNA expression and discusses the underlying mechanisms of mitomiRs-mtDNA interactions. Additionally, it provides new perspectives on precision therapeutic strategies, with a particular emphasis on mitomiRs-based regulation of mitochondrial function in mitochondrial-related diseases.

Cervical cancer is one of the most common gynecological malignant tumors in China. Given their lack of obviously early symptoms, more than half of patients with cervical cancer are diagnosed in the middle and late stages of this malignancy, resulting in poor prognosis. Finding new therapeutic targets is the current research direction. Metabolomics, as a new omics technology, is expected to provide new targets for tumor precision diagnosis and treatment through the analysis of the changes and potential mechanisms of metabolites in tumor occurrence and development by chromatography, mass spectrometry, and other technologies. Herein, we review the research methods of metabolomics; metabolic characteristics of cervical cancer; and progress of the research on metabolomics in cervical cancer diagnosis, curative effect prediction, and prognosis evaluation to provide new ideas for the precise diagnosis and treatment of cervical cancer.

The interactions between microorganisms and medicinal plants are crucial to the quality improvement of medicinal plants. Medicinal plants attract microorganisms to colonize by secreting specific compounds and provide niche and nutrient support for these microorganisms, with a symbiotic network formed. These microorganisms grow in the rhizosphere, phyllosphere, and endophytic tissues of plants and significantly improve the growth performance and medicinal component accumulation of medicinal plants by promoting nutrient uptake, enhancing disease resistance, and regulating the synthesis of secondary metabolites. Microorganisms are also widely used in the ecological planting of medicinal plants, and the growth conditions of medicinal plants are optimized by simulating the microbial effects in the natural environment. The interactions between microorganisms and medicinal plants not only significantly improve the yield and quality of medicinal plants but also enhance their geoherbalism, which is in line with the concept of green agriculture and eco-friendly development. This study reviewed the research results on the interactions between medicinal plants and microorganisms in recent years and focused on the analysis of the great potential of microorganisms in optimizing the growth environment of medicinal plants, regulating the accumulation of secondary metabolites, inducing systemic resistance, and promoting the ecological planting of medicinal plants. It provides a scientific basis for the research on the interactions between medicinal plants and microorganisms, the research and development of microbial agents, and the application of microorganisms in the ecological planting of medicinal plants and is of great significance for the quality improvement of medicinal plants and the green and sustainable development of TCM resources.

Non-small cell lung cancer(NSCLC) is the most common type of lung cancer worldwide, accounting for approximately 80%-85% of all lung cancer cases. Despite the clinical benefits of traditional treatments such as surgery, chemotherapy, and radiotherapy, challenges such as the high rate of postoperative recurrence and resistance of some patients to chemotherapy and targeted therapies limit their effectiveness, necessitating the exploration of more effective treatment options. In recent years, immunotherapy, especially immune checkpoint inhibitors(ICIs), has revolutionized NSCLC treatment and significantly improved the survival prognosis of some patients. However, the efficacy of immunotherapy is limited by tumor immune escape, drug resistance, and immune-related adverse events(irAEs), which have not been effectively addressed. Traditional Chinese medicine(TCM), as a traditional therapeutic approach, has shown unique advantages in NSCLC treatment, with studies indicating its ability to enhance immune responses, regulate immune checkpoints, and improve the tumor microenvironment(TME), thus boosting the efficacy of immunotherapy. Additionally, the multi-target and multi-pathway effects of TCM help mitigate the side effects of immunotherapy, further improving efficacy and safety. This review summarizes the latest research progress of TCM in NSCLC immunotherapy, focusing on the research results of TCM in enhancing the effect of immunotherapy by regulating immune cells, optimizing the immune microenvironment, and being applied with ICIs, etc. The latest research progress of TCM in alleviating irAEs is also elucidated. The aim is to provide theoretical support for the clinical application of TCM in the prevention and treatment of NSCLC and the research and development of new drugs and promote the optimization and development of combined immunotherapy and TCM treatment models.

This study investigated the therapeutic effects of Yiguanjian on dry eye in rats and its mechanisms involving the T helper cell 17(Th17)/regulatory T cell(Treg) balance. The rat model of dry eye was established by administrating 0.2% benzalkonium chloride solution in eye drops. After successful modeling, the rats were treated with Yiguanjian for 4 consecutive weeks. The Schirmer test was carried out to assess the lacrimal gland function, corneal fluorescence staining to detect corneal injury, hematoxylin-eosin staining to observe corneal histopathology, enzyme-linked immunosorbent assay to measure serum levels of interleukin(IL)-6, IL-8, IL-17A, IL-21, and tumor necrosis factor-α(TNF-α), RT-qPCR to analyze mRNA levels of retinoic acid receptor-related orphan receptor gamma t(RORγt) and forkhead box protein p3(Foxp3) in the corneal tissue, immunofluorescence double staining to evaluate RORγt and Foxp3 expression in the lacrimal gland tissue, and Western blot to quantify the protein levels of signal transducer and activator of transcription 3(STAT3), phosphorylated STAT3(p-STAT3), Janus kinase 2(Jak2), phosphorylated Jak2(p-Jak2), RORγt, and Foxp3 in the corneal tissue. The results demonstrated that Yiguanjian increased tear secretion(P<0.01), alleviated corneal damage and pathological changes, and lowered the serum levels of IL-6, IL-8, IL-17A, IL-21, and TNF-α(P<0.05) in model rats. Additionally, Yiguanjian decreased the ratio of RORγt to Foxp3 in the corneal and lacrimal gland tissue(P<0.01), downregulated the protein levels of STAT3, Jak2, and RORγt(P<0.05), upregulated the protein level of Foxp3(P<0.05), and inhibited phosphorylation of STAT3 and Jak2(P<0.01). These findings indicate that Yiguanjian ameliorates ocular surface dysfunction in dry eye rats by restoring Th17/Treg balance in the corneal and lacrimal gland tissue and suppressing systemic inflammatory cytokine release, thus mitigating ocular surface inflammation.

Endosomes are characterized by the presence of various phosphoinositides that are essential for defining the membrane properties. However, the interplay between endosomal phosphoinositides metabolism and innate immunity is yet to be fully understood. Here, our findings highlight the evolutionary continuity of RAB-10/Rab10's involvement in regulating innate immunity. Upon infection of Caenorhabditis elegans with Pseudomonas aeruginosa, an increase in RAB-10 activity was observed in the intestine. Conversely, when RAB-10 was absent, the intestinal diacylglycerols (DAGs) decreased, and the animal's response to the pathogen was impaired. Further research revealed that UNC-16/JIP3 acts as an RAB-10 effector, facilitating the recruitment of phospholipase EGL-8 to endosomes. This leads to a decrease in endosomal phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) and an elevation of DAGs, as well as the activation of the PMK-1/p38 MAPK innate immune pathway. It is noteworthy that the dimerization of UNC-16 is a prerequisite for its interaction with RAB-10(GTP) and the recruitment of EGL-8. Moreover, we ascertained that the rise in RAB-10 activity, due to infection, was attributed to the augmented expression of LET-413/Erbin, and the nuclear receptor NHR-25/NR5A1/2 was determined to be indispensable for this increase. Hence, this study illuminates the significance of endosomal PI(4,5)P2 catabolism in boosting innate immunity and outlines an NHR-25-mediated mechanism for pathogen detection in intestinal epithelia.

Hepatocellular carcinoma (HCC) is a common malignant tumor with a high mortality rate, an insidious onset, and complex pathological mechanisms. In the tumor microenvironment, tumor-promoting immune cells protect tumor cells from immune attacks, while dysfunction of anti-tumor immune cells causes the inhibition of immune response, thereby leading to the continuous deterioration of cancer. In recent years, traditional Chinese medicine has shown good efficacy in the treatment of HCC, and it can inhibit the proliferation and metastasis of cancer cells by regulating immune cells. By analyzing related articles in China and globally, this article summarizes how immune cells affect the progression of HCC through the immunosuppressive pathway and how traditional Chinese medicine exerts an anti-HCC effect by regulating immune cells, in order to provide theoretical basis and reference for optimizing the treatment of HCC.

ObjectiveTo evaluate the efficacy of Shexiang Baoxinwan in treating stable angina pectoris with Qi stagnation and blood stasis syndrome in patients with coronary artery disease (CAD) complicated with anxiety and depression and explore its underlying mechanisms. MethodsThis study employed a randomized, double-blind, and placebo-controlled clinical trial design. Patients admitted to the hospital were randomly assigned to the observation group and the control group, with 52 patients in each group. Patients in the observation and control groups received Shexiang Baoxinwan and placebo, respectively, both in combination with conventional Western medication. The dose was 45.0 mg, three times daily, for a total duration of eight weeks. The primary outcome was the Seattle Angina Questionnaire (SAQ) scores before and after treatment. Secondary outcomes included changes in traditional Chinese medicine (TCM) syndrome score, the patient health questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7), inflammatory markers [interleukin-18 (IL-18), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α), CD40, etc.], monoamine neurotransmitters [e.g., dopamine (DA)], vascular endothelial function markers [e.g., endothelin-1(ET-1)], adipokines, and ischemia-modified albumin (IMA). Adverse reactions were also recorded. ResultsA total of 92 patients completed the study, with 44 in the observation group and 48 in the control group. Compared with baseline, both groups showed significant decreases in PHQ-9, GAD-7, and TCM syndrome scores following treatment (P<0.05), along with a significant increase in SAQ scores (P<0.05). In the observation group, DA levels were significantly increased (P<0.05), while levels of IL-18, TNF-α, CD40, ET-1, and IMA were decreased (P<0.05). In contrast, the control group exhibited significantly increased CD40 levels (P<0.05). Compared with the control group after treatment, the observation group showed significant improvements in the SAQ dimensions of physical limitation, angina stability, treatment satisfaction, and disease perception, as well as in TCM syndrome score, PHQ-9 score, IL-18, CD40, ET-1, and IMA (P<0.05). No adverse reactions were observed in either group during treatment. ConclusionShexiang Baoxinwan can improve anxiety and depression, alleviate angina symptoms, and reduce TCM symptoms of Qi stagnation and blood stasis in CAD patients. The mechanism may involve anti-inflammation, improvement of vascular endothelial function, reduction of IMA, and increase of monoamine neurotransmitter levels.

Optical imaging is highly valued for its superior temporal and spatial resolution. This is particularly important in near-infrared II (NIR-II, 1 000-3 000 nm) imaging, which offers advantages such as reduced tissue absorption, minimal scattering, and low autofluorescence. These characteristics make NIR-II imaging especially suitable for deep tissue visualization, where high contrast and minimal background interference are critical for accurate diagnosis and monitoring. Currently, inorganic fluorescent probes—such as carbon nanotubes, rare earth nanoparticles, and quantum dots—offer high brightness and stability. However, they are hindered by ambiguous structures, larger sizes, and potential accumulation toxicity in vivo. In contrast, organic fluorescent probes, including small molecules and polymers, demonstrate higher biocompatibility but are limited by shorter emission wavelengths, lower quantum yields, and reduced stability. Recently, gold clusters have emerged as a promising class of nanomaterials with potential applications in biocatalysis, fluorescence sensing, biological imaging, and more. Water-soluble gold clusters are particularly attractive as fluorescent probes due to their remarkable optical properties, including strong photoluminescence, large Stokes shifts, and excellent photostability. Furthermore, their outstanding biocompatibility—attributed to good aqueous stability, ultra-small hydrodynamic size, and high renal clearance efficiency—makes them especially suitable for biomedical applications. Gold clusters hold significant potential for NIR-II fluorescence imaging. Atomic-precision gold clusters, typically composed of tens to hundreds of gold atoms and measuring only a few nanometers in diameter, possess well-defined three-dimensional structures and clear spatial coordination. This atomic-level precision enables fine-tuned structural regulation, further enhancing their fluorescence properties. Variations in cluster size, surface ligands, and alloying elements can result in distinct physicochemical characteristics. The incorporation of different atoms can modulate the atomic and electronic structures of gold clusters, while diverse ligands can influence surface polarity and steric hindrance. As such, strategies like alloying and ligand engineering are effective in enhancing both fluorescence and catalytic performance, thereby meeting a broader range of clinical needs. In recent years, gold clusters have attracted growing attention in the biomedical field. Their application in NIR-II imaging has led to significant progress in vascular, organ, and tumor imaging. The resulting high-resolution, high signal-to-noise imaging provides powerful tools for clinical diagnostics. Moreover, biologically active gold clusters can aid in drug delivery and disease diagnosis and treatment, offering new opportunities for clinical therapeutics. Despite the notable achievements in fundamental research and clinical translation, further studies are required to address challenges related to the standardized synthesis and complex metabolic behavior of gold clusters. Resolving these issues will help accelerate their clinical adoption and broaden their biomedical applications.
