Radar-based non-contact health monitoring technology (RBNHMT) has emerged as a transformative paradigm in continuous health sensing, enabling non-invasive and continuous monitoring of physiological parameters and behavioral patterns by transmitting electromagnetic waves, analyzing the reflected signals, and detecting subtle bodily movements—ranging from millimeter-scale chest wall displacements due to respiration to micro-scale vibrations associated with cardiac activity—ultimately transforming them into quantifiable health data. Distinguished by its non-contact operation, inherent privacy preservation, and adaptability to diverse scenarios, RBNHMT exhibits stronger resistance to environmental interference than conventional contact-based monitoring, and has solidified its position as a prominent and dynamic research focus in the field of non-contact health monitoring. Currently, significant and multifaceted progress has been made across several key areas. In human activity recognition (HAR), systems leveraging micro-Doppler signatures or point cloud sequences achieve high-precision detection of gait, gestures, and fall events, with state-of-the-art deep learning-based models achieving accuracy rates exceeding 99% in controlled experimental settings. For vital sign and sleep monitoring, it not only tracks respiratory and heart rates continuously but also extracts clinically relevant metrics such as heart rate variability (HRV) for autonomic nervous system assessment and estimates blood pressure through indirect methods like pulse transit time analysis, while maintaining robustness in dynamic settings through advanced motion compensation algorithms. In sleep monitoring, it further enables sleep posture classification and apnea event detection. In emotion and stress recognition, it provides a non-intrusive approach for psychological assessment by analyzing autonomic-response physiological signal patterns or behavioral features. Furthermore, its applications in auxiliary medical diagnosis have expanded to promising interdisciplinary areas such as non-contact heart sound auscultation, radar-based screening for obstructive sleep apnea (OSA), and emerging research into breast cancer detection using microwave and millimeter-wave imaging techniques. However, several challenges impede its practical deployment. Signal quality is significantly compromised by multipath interference in complex indoor environments and clutter from static objects, and by motion artifacts in dynamic scenarios where gross body movements obscure the subtle physiological signals. Algorithmically, separating signals from multiple targets in close proximity and calibrating for substantial individual physiological differences, such as body habitus, baseline vital signs, remain difficult and limit generalizability. Hardware design also faces the challenge of balancing power consumption, cost, integration, and performance, often requiring trade-offs that constrain miniaturization, battery life, or measurement sensitivity. Future advancement, therefore, requires collaborative and targeted innovation across multiple dimensions. Algorithmically, developing adaptive signal processing models based on emerging paradigms such as few-shot learning (for user-specific calibration with minimal data) and reinforcement learning (for dynamic noise suppression) is essential. At the hardware level, highly integrated radar SoCs with embedded processing capabilities and advanced packaging technologies are crucial for achieving the dual goals of device miniaturization and cost reduction without sacrificing performance. At the system level, fusing radar data with complementary modalities such as infrared and acoustic sensing can create a synergistic, multi-modal framework that significantly enhances perceptual robustness and reliability in complex, real-world environments. This review provides a comprehensive synthesis that systematically summarizes the relevant theoretical foundations and application progress, and offers an in-depth analysis of the current technical bottlenecks. It aims to provide a clear development path and a foundational academic reference for the in-depth integration and practical application of RBNHMT in critical scenarios including rehabilitation engineering, smart elderly care, in-vehicle health monitoring, and beyond, thereby offering innovative technical support for the vision of universal, proactive, and personalized health management.

Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality, characterized by poor prognosis due to its high proliferative and invasive potential. Tumor metabolic reprogramming, particularly involving glucose metabolism, is essential for tumor survival. This study investigates the role of the Hippo pathway effector transcriptional co-activator with PDZ-binding motif (TAZ) in regulating gluconeogenesis and promoting tumorigenesis in HCC. Methods: TAZ expression in HCC was analyzed using The Cancer Genome Atlas data and validated in clinical samples and cell lines. TAZ was overexpressed or silenced in HCC cell lines to evaluate its effects on cell proliferation, apoptosis, migration, and invasion. The expression and prognostic relevance of the gluconeogenesis-related genes phosphoenolpyruvate carboxykinase 1 (PCK1) and glucose-6-phosphatase (G6PC) were examined, along with their correlation with TAZ expression. Tumor growth was assessed in nude mice. Interactions between TAZ and the glucocorticoid receptor (GR) were investigated using co-immunoprecipitation, immunofluorescence, and chromatin immunoprecipitation assays. Results: TAZ was significantly upregulated in HCC tissues and cell lines. TAZ overexpression enhanced proliferation, reduced apoptosis, and promoted migration and invasion. In contrast, PCK1 and G6PC were downregulated in HCC and showed a negative correlation with TAZ expression. Conclusion TAZ modulates gluconeogenesis and accelerates tumor growth, whereas its knockdown attenuates tumor progression. TAZ interacts with GR, suppressing its transcriptional activity on gluconeogenic gene promoters.

Objective: To analyze the changes in serum ghrelin and leptin levels in girls with central precocious puberty (CPP) after 24 weeks of aerobic training combined with gonadotropin releasing hormone agonist (GnRH-a) therapy, so as to provide reference for preventing girls from precocious puberty. Methods: A total of 96 girls with CPP who were treated at the Affiliated Huai an Hospital of Xuzhou Medical University between April 2022 and January 2024 were selected as study subjects. They were divided into a pharmacotherapy group and a combined pharmacotherapy and aerobic exercise group by random number table method, with 48 patients in each group. The pharmacotherapy group received subcutaneous injections of leuprorelin acetate microspheres at a dose of 100 μg/kg in the morning (8:00-10:00), administered once every 4 weeks for a total of 6 injections. The combined pharmacotherapy and aerobic exercise group participated in aerobic exercise in addition to the subcutaneous injections of leuprorelin acetate microspheres; the training was conducted for 24 weeks, 3 times per week, and was conducted after school for girls, for 20- 75 min per session. The t test was utilized to comparatively analyze the serum leptin and ghrelin levels of the patients in both groups before and after the intervention. Binary Logistic regression analysis was applied to explore the correlative factors influencing serum ghrelin and leptin levels in girls with CPP post intervention. Results: Following the intervention, the serum leptin [(7.85± 1.43)ng/mL ] and ghrelin [(8.46±1.06)ng/mL] levels in the girls of the pharmacotherapy group demonstrated no statistically significant changes compared to their pre intervention levels [(7.94±1.45) (8.35±1.22)ng/mL, respectively] ( t =0.41, -0.58, both P > 0.05 ). Conversely, in the combined pharmacotherapy and aerobic exercise group, the post intervention serum leptin levels [(6.35±1.62) ng/mL] significantly decreased compared to pre intervention [(7.87±1.59) ng/mL], and the serum ghrelin levels [(9.12±1.37) ng/mL] significantly increased compared to pre intervention [(8.22±1.47) ng/mL] ( t =6.20, 4.39, both P <0.05). Conclusion Aerobic training increases serum ghrelin levels and decreases serum leptin levels in girls with CPP.

OBJECTIVE To investigate the mechanism through which Danggui buxue decoction regulates neutrophil extracellular traps （NETs） to improve osteoporosis （OP） in rats with premature ovarian failure （POF）. METHODS Female SD rats were randomly divided into normal group， model group， calcitriol group， and Danggui buxue decoction low-dose， medium-dose and high-dose groups， with 9 rats in each group. Except for the normal group， all other groups were administered cisplatin via intraperitoneal injection on days 1 and 8 to establish a POF complicated with OP model. Each group received the corresponding drugs or normal saline intragastrically starting from day 5， once a day， for 4 consecutive weeks. After the last medication， serum levels of estradiol （E2）， NETs， 25-hydroxyvitamin D3 [25（OH）D3]， receptor activator of nuclear factor-κB ligand （RANKL）， and osteocalcin （BGP） were measured. The histopathological changes in bone tissue were observed. The expressions of vitamin D receptor （VDR）， myeloperoxidase （MPO）， neutrophil elastase （NE） and citrullinated histone H3 （CitH3） in bone tissue were detected； the protein expressions of 25-hydroxyvitamin D-1α-hydroxylase （CYP27B1） and 1α，25-dihydroxyvitamin D3-24-hydroxylase （CYP24A1） were also determined. RESULTS Compared with the normal group， the bone tissue of rats in the model group showed a significant reduction in the number of trabeculae， which was thinner broken and poorly connected， with significant destruction of the reticular structure， and an enlarged marrow cavity. Serum levels of NETs and RANKL， the protein expressions of MPO， NE， CitH3 and CYP24A1 in bone tissue were significantly increased or upregulated， while serum levels of E2， 25（OH）D3 and BGP as well as protein expressions of VDR and CYP27B1 were significantly decreased or downregulated （P＜0.05）. Compared with the model group， the histopathological changes in the bone tissue of rats in each administration group showed some degree of recovery， with significant improvements observed in most quantitative indicators （P＜0.05）. CONCLUSIONS Danggui buxue decoction can restore the E2 level in POF complicated with OP rats， and improve OP. The mechanism may be related to its ability to upregulate VD level and inhibit the formation of NETs.

Based on the theory of 'bi （痹） of both body and viscera'， this paper systematically discussed the pathogenic evolution of rheumatoid arthritis （RA） complicated by sarcopenia from the perspective of traditional Chinese medicine （TCM）. It is proposed that a transformation pathway is muscle bi to spleen bi and then atrophy bi， and the core pathogenesis is diaharmony of ying （营） and wei （卫）. Combining modern molecular biology research， it is suggested that imbalances in skeletal muscle homeostasis mediated by the tumor necrosis factor-like weak inducer of apoptosis-ibroblast growth factor-inducible 14 （TWEAK-Fn14） axis may provide the material basis for the evolution of this disease. Furthermore， this authors proposed TCM treatment strategies， including "regulating and tonifying ying and wei， warming yang and moving bi， nourishing the viscera by supporting the body"， and "promoting the spleen and resolving turbidity， clearing heat and promoting circulation， regulating the organs and calming the body". These strategies emphasize the simultaneous treatment of body and viscera， integrated prevention and treatment， so as to provide TCM theoretical foundation and clinical approaches for preventing and treating RA complicated by sarcopenia.

ObjectiveRecent studies have highlighted the critical role of NUDT19 in the initiation, progression, and prognosis of specific cancer types. However, its involvement in pan-cancer analysis has not been fully characterized. This study aims to systematically explore the expression patterns, clinical significance, and immune-related functions of NUDT19 in various cancer types through multi-omics analysis, further revealing its potential role in cancer, particularly its functional and therapeutic target value in leukemia. MethodsTo achieve this goal, various bioinformatics approaches were employed to evaluate the expression patterns, clinical significance, and immune-related functions of NUDT19 in tumors and normal tissues. Additionally, we analyzed the mutation characteristics of NUDT19 and its relationship with epigenetic modifications. Using the single-cell analysis tool SingleCellBase, we explored the distribution of NUDT19 across different cell subpopulations in tumors. To validate these findings, qRT-PCR was used to measure NUDT19 expression levels in specific tumor cell lines, and we established acute myeloid leukemia (AML) cell lines (HL-60 and THP-1) to conduct NUDT19 knockdown and overexpression experiments, assessing its effects on leukemia cell proliferation, apoptosis, and invasion. ResultsPan-cancer analysis revealed the dysregulated expression of NUDT19 across multiple cancer types, which was closely associated with poor prognosis, clinical staging, and diagnostic markers. Furthermore, NUDT19 was significantly correlated with tumor biomarkers, immune-related genes, and immune cell infiltration in different cancers. Mutation analysis showed that multiple mutations in NUDT19 were significantly associated with epigenetic changes. Single-cell analysis revealed the heterogeneity of NUDT19 expression in cancer cells, suggesting its potentially diverse functional roles in different cell subpopulations. qRT-PCR experiments confirmed the significant upregulation of NUDT19 in various tumor cell lines. In AML cell lines, NUDT19 knockdown led to reduced cell proliferation and invasion, with increased apoptosis, while NUDT19 overexpression significantly enhanced cell proliferation and invasion while reducing apoptosis. ConclusionThis study demonstrates the diverse roles of NUDT19 in various cancer types, with a particularly prominent functional role in leukemia. NUDT19 is not only associated with tumor initiation and progression but may also influence cancer progression through the regulation of immune microenvironment and epigenetic mechanisms. Our research highlights the potential of NUDT19 as a therapeutic target, particularly for targeted therapies in malignancies such as leukemia, with significant clinical application prospects.

Objective To explore the symptom clusters in renal transplant recipients and con-struct a concurrent symptom network to identify core symptoms.Methods A total of 343 patients with followed up after renal transplantation were selected as the study subjects.A general information questionnaire and the Chinese version of the Modified Transplant Symptom Occurrence and Symptom Distress Scale were employed to analyze the occurrence of symptoms in patients.In this study,only symptoms with an incidence rate greater than 20％and Spearman correlation coefficient greater than 0.40 between symptom severity and total score were retained.Exploratory factor analysis was used to extract symptom clusters with a factor loading of ≥0.45 as the criterion.The R language was utilized to construct symptom network,based on which core symptoms and bridge symptoms were identified.Results A total of 5 symptom clusters were extracted in this study:the neuro-gastrointestinal symp-tom cluster,the mood-related symptom cluster,the hormone-related symptom cluster,the energy de-ficiency symptom cluster and the vision-related symptom cluster.The core symptoms were anxiety(rs=1.75),mood swings(rs=1.50)and muscle weakness(rs=1.27).The top three symptoms in terms of bridge strength were muscle weakness(rb=0.87),lack of vitality(rb=0.66)and fa-tigue(rb=0.65).Conclusion Multiple symptoms are presented in patients after renal transplanta-tion.Based on the results of symptom network analysis,clinicians can strengthen the assessment of core symptoms and bridge symptoms to develop precise intervention strategies and improve the effectiveness of symptom management.

OBJECTIVE: To elucidate the specific mechanisms by which electroacupuncture (EA) alleviates anxiety and fear behaviors associated with posttraumatic stress disorder (PTSD), focusing on the role of lipocalin-2 (Lcn2). METHODS: The PTSD mouse model was subjected to single prolonged stress and shock (SPS&S), and the animals received 15 min sessions of EA at Shenmen acupoint (HT7). Behavioral tests were used to investigate the effects of EA at HT7 on anxiety and fear. Western blotting and enzyme-linked immunosorbent assay were used to quantify Lcn2 and inflammatory cytokine levels in the prefrontal cortex (PFC). Additionally, the activity of PFC neurons was evaluated by immunofluorescence and in vivo electrophysiology. RESULTS: Mice subjected to SPS&S presented increased anxiety- and fear-like behaviors. Lcn2 expression in the PFC was significantly upregulated following SPS&S, leading to increased expression of the proinflammatory cytokines tumor necrosis factor-α and interleukin-6 and suppression of PFC neuronal activity. However, EA at HT7 inhibited Lcn2 release, reducing neuroinflammation and hypoexcitability in the PFC. Lcn2 overexpression mitigated the effects of EA at HT7, resulting in anxiety- and fear-like behaviors. CONCLUSION EA at HT7 can ameliorate PTSD-associated anxiety and fear, and its mechanism of action appears to involve the inhibition of Lcn2-mediated neural activity and inflammation in the PFC.

This study aims to investigate the pharmacological effects and mechanisms of Yougui Yin in treating glucocorticoid-induced osteonecrosis. A rat model of glucocorticoid-associated osteonecrosis of the femoral head(GA-ONFH) was established by intramuscular injection of dexamethasone at 20 mg·kg~(-1) every other day for 8 weeks. Rats were randomly allocated into control, model, and low-and high-dose(1.5 and 3.0 g·kg~(-1), respectively) Yougui Yin groups. After modeling, rats in Yougui Yin groups were administrated with Yougui Yin via gavage, which was followed by femoral specimen collection. Hematoxylin-eosin staining was employed to observe femoral head repair, and immunofluorescence was employed to assess adipogenic differentiation of bone marrow mesenchymal stem cells(BMSCs) within the femoral head. Cell experiments were carried out with dexamethasone(1 μmol·L~(-1))-treated BMSCs to evaluate the effects of Yougui Yin-medicated serum on adipogenic differentiation. Animal experiments demonstrated that compared with the model group, Yougui Yin at both high and low doses significantly improved bone mineral density(BMD), bone volume/total volume(BV/TV) ratio, and trabecular thickness(Tb.Th) in the femoral head. Additionally, Yougui Yin alleviated necrosis-like changes and adipocyte infiltration and significantly reduced the expression level of peroxisome proliferator-activated receptor γ(PPARγ) in the femoral head, thereby suppressing the adipogenic differentiation of BMSCs in GA-ONFH rats. The cell experiments revealed that Yougui Yin-medicated serum markedly inhibited dexamethasone-induced adipogenic differentiation of BMSCs and down-regulated the level of PPARγ. The overexpression of PPARγ attenuated the inhibitory effect of Yougui Yin-medicated serum on the adipogenic differentiation of BMSCs, indicating the critical role of PPARγ in Yougui Yin-mediated suppression of adipogenic differentiation of BMSCs. In conclusion, Yougui Yin exerts therapeutic effects on glucocorticoid-induced osteonecrosis by down-regulating PPARγ expression and inhibiting adipogenic differentiation of BMSCs.
