Huo Xue Tong Luo Capsule (HXTL) has been clinically used to treat osteonecrosis of the femoral head, osteoporosis, and other bone and joint diseases with promising effects. Our previous study has shown that HXTL can promote osteogenesis in mesenchymal stem cells by inhibiting lncRNA-Miat expression through histone modifications. However, the mechanism by which HXTL treats postmenopausal osteoporosis (PMOP) remains unclear. In this study, we used network pharmacology-based mechanism prediction, molecular docking, and pharmacological validation to investigate the mechanism of HXTL in treating PMOP.

The key candidate targets and relevant signaling pathways of HXTL for PMOP treatment were predicted using network pharmacology and molecular docking analysis. RAW264.7 cells were used for Western blot to validate the predicted mechanistic pathways. The ovaries of mice were surgically removed to simulate PMOP. The effect of HXTL on PMOP was evaluated using tartrate-resistant acid phosphatase staining and immunohistochemical assays in vivo.

Network pharmacology analysis suggested that HXTL interacted with 215 key targets linked to PMOP, primarily affecting the PI3K-AKT signaling pathway. Molecular docking showed that the main components of HXTL exhibited strong binding affinity to NFATc1, p-PI3K, and p-AKT1. Furthermore, our in vitro results confirmed that HXTL suppressed the PI3K-AKT signaling pathway. In vivo, HE and tartrate-resistant acid phosphatase staining results showed that HXTL inhibited osteoclast formation and protected bone mass.

This research demonstrated that HXTL could inhibit osteoclast formation and prevent bone loss induced by ovariectomy in mice by inhibiting the PI3K-AKT signaling pathway. These findings provide important evidence for the clinical application of HXTL in treating PMOP.

Breast cancer remains one of the leading causes of cancer-related deaths worldwide. Early detection of breast cancer significantly improves outcomes and survival rates, minimizing treatments. Imaging techniques are critical in identifying abnormalities and diagnosing breast cancer at its earliest stages, often before clinical symptoms emerge. Mammography remains standard for screening in average-risk women, while supplementary methods like ultrasound, magnetic resonance imaging, and tomosynthesis enhance detection rates, particularly in women with dense breasts or those at high risk. Given that certain factors, such as family history, age, genetic mutations, and breast density, affect the risk of developing breast cancer, some women may benefit from earlier or more frequent screenings. Personalized screening protocols are becoming more common, tailoring the type and frequency of imaging to the individual’s risk profile. Newer technologies, such as molecular breast imaging and contrast-enhanced mammography show promise but require further validation for widespread use. In conclusion, imaging techniques including mammography, ultrasound, magnetic resonance imaging, and newer technologies like three-dimensional mammography and molecular breast imaging are essential tools in the early detection of breast cancer, leading to better outcomes for patients. This literature review provides an overview of current breast cancer imaging methods, their role in early diagnosis, and their effectiveness and limitations.

Traditional Chinese medicine (TCM) is widely used in cancer care in China as an integral part of treatment. This study aimed to understand the motivations of cancer patients in China for adopting TCM in their treatment and to examine their communication with oncologists. Gaining insights into these factors can enhance culturally sensitive, patient-centered oncology care.

A consecutive sample of 287 outpatients with cancer was recruited. Sociodemographic and clinical data, TCM usage, primary reasons for adopting TCM, and communication about TCM with oncologists were collected. Descriptive statistics, binary logistic regression, and thematic analysis were used to analyze the data.

Patients’ primary reasons for choosing TCM fell into five main categories: (1) belief in the benefits of TCM itself, (2) recommendations from others (family, friends, or oncologists), (3) belief in the benefits of combining TCM with Western medicine (WM), (4) previous positive experiences with TCM, and (5) dissatisfaction with or intolerance to WM. Among the 103 patients who consulted external TCM providers, 65% disclosed this to their oncologists. A longer time since diagnosis was associated with a higher likelihood of disclosure, while employed patients were less likely to inform their oncologists. Oncologists’ responses varied, with 55% neither approving nor disapproving of external TCM prescriptions.

The primary reasons for TCM use were perceived benefits and recommendations from oncologists and family members. However, communication about TCM with oncologists remains inconsistent. Enhancing patient-provider communication through education and fostering the integration of TCM and WM can improve holistic cancer care.

Chronic obstructive pulmonary disease (COPD) is an irreversible inflammatory lung disease. Studies have shown that macrophages and estrogen receptors play a pivotal regulatory role in the development of COPD. Ejiao (Colla Corii Asini, CCA, or donkey-hide gelatin), a traditional Chinese medicine, has anti-inflammatory and lung function-protective effects, but its specific mechanism in COPD remains unclear. This study aimed to explore the immunomodulatory effects of Ejiao on COPD, focusing on its impact on inflammatory pathways and macrophages.

This study is the first to apply a network pharmacology approach to explore the potential mechanisms underlying Ejiao’s therapeutic effects on COPD. We collected the peptides and chemical components of Ejiao and used the STRING database to screen for COPD-related targets of Ejiao components, constructing a drug-molecular network. Additionally, we established cigarette smoke extract (CSE) and lipopolysaccharide-induced cell injury models and treated them with Ejiao-containing serum. Western blot (WB) analysis was used to detect the expression of related proteins, enabling a preliminary exploration of Ejiao’s effects and regulatory mechanisms. In further experiments, a mouse COPD model was established, and eight weeks of Ejiao intervention were conducted. We assessed lung function, pathological changes in lung tissue, monitored cytokine levels in serum and bronchoalveolar lavage fluid, performed flow cytometry to evaluate abdominal macrophage levels, and conducted WB to analyze protein expression, providing an in-depth study of Ejiao’s regulatory effects on the mouse COPD model.

The findings from the network pharmacology analysis suggest a potential regulatory role of the estrogen receptor pathway in COPD. CSE stimulation of RAW264.7 cells resulted in elevated tumor necrosis factor-α levels, decreased interleukin-10 levels, reduced expression of estrogen receptors (ERs) α and β, decreased inhibitor of NF-κB levels, and increased p-AKT levels. Following Ejiao intervention, interleukin-10, ERα+β, and inhibitor of NF-κB levels increased, while p-AKT levels decreased. Ejiao significantly improved lung function in CSE/lipopolysaccharide-induced COPD mice, reduced the number of macrophages, lowered the levels of inflammatory factors in bronchoalveolar lavage fluid, and increased estradiol levels in serum. WB results indicated that Ejiao may ameliorate lung injury in COPD by modulating the ER/AKT/NF-κB pathway.

The results suggest that Ejiao may improve lung injury and inflammation in CSE/ lipopolysaccharide-induced COPD by regulating the ER/AKT/NF-κB pathway.

Mitochondria are highly dynamic organelles that adapt to cellular stress and metabolic demands through processes such as fission, fusion, mitophagy, and transport, all of which are vital for maintaining cellular signaling and metabolic homeostasis. Fission facilitates mitochondrial division and biogenesis, while fusion enhances mitochondrial fitness and metabolic flexibility by mitigating damage. Together, these processes play a critical role in regulating cellular stress responses and apoptosis. Dysregulation of mitochondrial dynamics has been linked to impaired development and cancer progression, including breast cancer metastasis. A comprehensive understanding of mitochondrial dynamics in breast cancer progression is essential for advancing precision medicine. This review delves into the intricate molecular mechanisms governing mitochondrial biogenesis, fission, fusion, and mitophagy, with a particular focus on the role of mitophagy in maintaining mitochondrial homeostasis and its connection to metastasis progression. Furthermore, it discusses potential therapeutic strategies targeting mitochondrial dynamics and highlights the critical steps necessary to translate these approaches into clinical trials.

This review explores the complex interplay between the microbiome and human aging, highlighting how dysbiosis impacts host physiology and health, particularly in relation to genomic stability and telomere attrition. Recent advances in cellular and molecular biology have underscored the role of both intrinsic and extrinsic factors in human aging, with the microbiome emerging as a key determinant of host physiology and health. Dysbiosis—disruptions in microbiome composition—is linked to various age-related diseases and impacts genomic stability and telomere attrition, the progressive shortening of telomeres that limits cell division and contributes to aging. This review examines how microbiome dynamics influence aging by triggering inflammation, oxidative stress, immune dysregulation, and metabolic dysfunction, all of which affect two primary hallmarks of aging: genomic instability and telomere attrition. Understanding these interactions is essential for developing targeted interventions to restore microbiome balance and promote healthy aging, offering potential treatments to extend healthspan and alleviate aging-related diseases. The convergence of microbiome and aging research promises transformative insights and new avenues for improving global population well-being.

The Chinese caterpillar fungus Ophiocordyceps sinensis (Berk.) is a valuable traditional medicine, also known throughout Asia by its Tibetan name དབྱར་རྩྭ་དགུན་འབུ (Yartsa Gunbu), meaning “summer grass, winter worm”. The mature fungus O. sinensis contains abundant active biological components, including polysaccharides, alkaloids, amino acids, inorganic elements, and others. Studies have previously confirmed that O. sinensis possesses multiple pharmacological activities. Therefore, it holds high value in the commercial market and is in increasing demand. However, the unique formation process and harsh growth environment contribute to the preciousness and scarcity of the species. To meet market demand, multiple mycelium types have been isolated from natural O. sinensis and cultivated artificially using fermentation technology. Currently, both natural and cultivated O. sinensis products are available as healthy Chinese herbal medicines on the market. However, there is a lack of comparative reviews on the two types of O. sinensis in terms of their compositions and medicinal functions. This mini-review will focus on the bioactive ingredients and medicinal functions of both natural and cultivated O. sinensis, intending to elucidate their medical values as traditional Chinese medicines for human use.
