Rheumatoid arthritis belongs to arthralgia syndrome in the theory of traditional Chinese medicine, and cold-dampness obstruction syndrome and dampness-heat obstruction syndrome are core syndromes and main syndrome differentiation types of this disease. Fine therapeutic effects have been obtained in the long-term clinical practice of many famous traditional Chinese medicine practitioners following the syndrome differentiation and treatment based on the guiding principles of cold and heat. To adapt to the clinical diagnosis practice of combining disease differentiation and syndrome differentiation, and to better carry out basic research on integrated Chinese and Western medicine and preclinical study on new traditional Chinese medicines, Guidelines for Establishing Animal Models of Rheumatoid Arthritis with Cold-Dampness Obstruction Syndrome and Dampness-Heat Obstruction Syndrome (hereinafter referred to as the Guidelines) were compiled by our research group, in cooperation with the renowned experts in research fields including traditional Chinese medicine, clinical medicine, zoology and evidence-based medicine, which provide a meaningful reference for scientific research, teaching and clinical applications. The compilation process of the Guidelines was guided by the theory of disease and syndrome integration and the principles of "evidence takes the main place, consensus plays an auxiliary role, and experience serves as the reference". Based on the comprehensive evaluation of pathogenesis homology, behavioral phenotypic consistency, and drug treatment predictability compared between animal models and human diseases, by the nominal group method, "recommendations" were formed for recommendations supported by evidence, and "consensus recommendations" were formed for recommendations not supported by evidence. Guidelines were formed involving content such as animal types, arthritis modeling methods, external stimulation conditions, and modeling assessment indicators during the establishment of the animal models of rheumatoid arthritis with cold-dampness obstruction syndrome and dampness-heat obstruction syndrome. The Guidelines are applicable for the disease and syndrome research on rheumatoid arthritis, investigation of therapeutic mechanisms, and development of new traditional Chinese medicine. The Guidelines also provide a reference for the establishment of guidelines on other types of diseases and syndromes combined with animal models to further promote the modernization of traditional Chinese medicine research and its integration with international academic development.

RNA modifications constitute a crucial class of post-transcriptional chemical alterations that profoundly influence RNA stability and translational efficiency, thereby shaping cellular protein expression profiles. These diverse chemical marks are ubiquitously involved in key biological processes, including cell proliferation, differentiation, apoptosis, and metastatic potential, and they exert precise regulatory control over these functions. A major advance in the field is the recognition that RNA modifications do not act in isolation. Instead, they participate in complex, dynamic interactions—through synergistic enhancement, antagonism, competitive binding, and functional crosstalk—forming what is now termed the “RNA modification interactome” or “RNA modification interaction network.” The formation and functional operation of this interactome rely on a multilayered regulatory framework orchestrated by RNA-modifying enzymes—commonly referred to as “writers,” “erasers,” and “readers.” These enzymes exhibit hierarchical organization within signaling cascades, often functioning in upstream-downstream sequences and converging at critical regulatory nodes. Their integration is further mediated through shared regulatory elements or the assembly into multi-enzyme complexes. This intricate enzymatic network directly governs and shapes the interdependent relationships among various RNA modifications. This review systematically elucidates the molecular mechanisms underlying both direct and indirect interactions between RNA modifications. Building upon this foundation, we introduce novel quantitative assessment frameworks and predictive disease models designed to leverage these interaction patterns. Importantly, studies across multiple disease contexts have identified core downstream signaling axes driven by specific constellations of interacting RNA modifications. These findings not only deepen our understanding of how RNA modification crosstalk contributes to disease initiation and progression, but also highlight its translational potential. This potential is exemplified by the discovery of diagnostic biomarkers based on interaction signatures and the development of therapeutic strategies targeting pathogenic modification networks. Together, these insights provide a conceptual framework for understanding the dynamic and multidimensional regulatory roles of RNA modifications in cellular systems. In conclusion, the emerging concept of RNA modification crosstalk reveals the extraordinary complexity of post-transcriptional regulation and opens new research avenues. It offers critical insights into the central question of how RNA-modifying enzymes achieve substrate specificity—determining which nucleotides within specific RNA transcripts are selectively modified during defined developmental or pathological stages. Decoding these specificity determinants, shaped in large part by the modification interactome, is essential for fully understanding the biological and pathological significance of the epitranscriptome.

Breast cancer is one of the most common and fatal malignancies among women worldwide, and its treatment efficacy is often limited by drug resistance and the presence of undruggable targets. Traditional small-molecule drugs have difficulty effectively modulating certain critical targets such as transcription factors and non-coding RNAs, necessitating new therapeutic strategies. Proteolysis-targeting chimeras (PROTACs) function by recruiting pathogenic proteins to the cellular ubiquitin-proteasome system, thereby inducing their specific degradation. In contrast, ribonuclease-targeting chimeras (RIBOTACs) utilize small-molecule ligands but bind to RNA and direct endogenous RNases to selectively degrade pathogenic RNA molecules. By employing a "degradation rather than inhibition" mechanism, targeting chimera technology broadens the druggable landscape and offers a novel precision therapeutic strategy for breast cancer, particularly for refractory and drug-resistant cases. This approach not only overcomes the limitations of traditional drugs, such as the absence of suitable binding sites or poor selectivity, but also reduces required dosages and potential adverse effects. Recent studies have preliminarily demonstrated the therapeutic potential of PROTACs and RIBOTACs in breast cancer, encompassing target design, mechanistic investigation, and preclinical as well as early clinical applications. Research into these technologies reveals their ability to tackle previously undruggable targets, thereby providing theoretical support for the development of safer and more effective precision therapies for breast cancer. In the future, with advances in drug delivery systems and clinical trials, PROTACs and RIBOTACs are expected to be used synergistically with immunotherapy and chemotherapy, offering breast cancer patients more promising comprehensive treatment options and potentially driving oncology toward broader intervention of undruggable targets.

OBJECTIVES:
To explore the therapeutic mechanism of Guizhi Fuling (GZFL) Pellets against cervical cancer.
METHODS:
Publicly available databases were used to identify the targets of GZFL Pellets and cervical cancer to construct the protein-protein interaction (PPI) network, followed by GO biological process and KEGG pathway enrichment analysis of the hub genes. The "Traditional Chinese Medicine-Active Ingredients-Targets-Pathways" network for GZFL Pellets in cervical cancer treatment was generated using Cytoscape v10.0.0, and molecular docking of the drug and potential targets was performed to predict the specific targets of active components in Guizhi Fuling Pellets. The inhibitory effects of hederagenin, an active ingredient in GZFL Pellets, was tested in cultured cervical cancer cells and in nude mice bearing cervical cancer xenografts.
RESULTS:
GZFL Pellets contain 338 active components targeting 247 action sites. A total of 10127 cervical cancer-related targets were obtained, and among them 195 were identified as potential therapeutic targets of GZFL Pellets for cervical cancer treatment, including the key targets of GABRA1, PTK2, JAK2, HTR3A, GSR, and IL-17. Molecular docking study showed low binding energies of the active components such as hederagenin, campesterol, and stigmasterol for protein-molecule interaction. GO enrichment analysis suggested that GZFL Pellets inhibited cervical cancer primarily by regulating responses to steroid hormones, oxidative stress, and lipopolysaccharides. Among the active components of GZFL Pellets, hederagenin was found to inhibit cervical cancer cells in vitro and significantly reduced STAT3 phosphorylation level in the cancer cells. In nude mice bearing cervical cancer xenografts, hederagenin effectively inhibited tumor growth rate without causing obvious adverse effects.
CONCLUSIONS
GZFL Pellets inhibit cervical cancer cell growth through its multiple active components that target different pathways. Among these components, hederagenin inhibits tumor cell growth possibly by directly binding to JAK2 protein to inhibit STAT3 phosphorylation.

Objective To analyze the current status and latent profiles on the decision fatigue of nurses. Methods A total of 812 nurses from four public tertiary hospitals in Guangdong Province were selected as the research subjects using the convenience sampling method. The Decisional Fatigue Scale, the Nursing Work Environment Scale, the Nurses Job Stress Scale, and the Chinese version of 10-item Connor-Davidson Resilience Scale were used to assess the level of decision fatigue, work environment, job stress level, and resilience among nurses. The characteristics of latent profiles on the decision fatigue of nurses were analyzed, and multinomial logistic regression was used to analyze the influencing factors of latent profiles on the decision fatigue of nurses. Results The median and 25th and 75th percentiles of the scores of the decision fatigue of nurses were 10.0 (9.0, 15.0). The average scores for work environment, job stress, and resilience were (107.9±24.0), (86.1±23.8), and (23.6 ± 8.3), respectively. The result of latent profile analysis showed that the decision fatigue of nurses could be classified into three types: low fatigue-energetic, medium fatigue-avoidant and high fatigue-burnout, accounting for 15.0%, 59.6%, and 25.4%, respectively. The results of multinomial logistic regression showed that the risk of being classified as medium fatigue-avoidant was higher among practice nurse than nurse (P<0.05). Nurse with a monthly income of 5 000 to 10 000 yuan had higher risk of being classified as medium fatigue-avoidant than those with >10 000 yuan (P<0.05). And nurse with poorer work environment scores had higher risk of being classified as medium fatigue-avoidant than those with higher scores (P<0.01). Nurse with higher score on job stress and lower score on resilience had higher risk of being classified as medium fatigue-avoidant and high fatigue-burnout, than those with lower score of job stress and higher score on resilience (all P<0.01). Conclusion There is a heterogeneity in the decision fatigue of nurses, which can be categorized into three categories: low fatigue-energetic, medium fatigue-avoidant and high fatigue-burnout. The influencing factors of latent profile on the decision fatigue of nurses are job title, individual monthly income, work environment, job stress, and resilience.

OBJECTIVE:
To explore method and clinical effect of microsurgical thinned anterolateral thigh perforator flap to repair soft tissue defects of foot and ankle.
METHODS:
From March 2017 to January 2022, totally 20 patients with soft tissue defects of ankle joint were treated with micro-thinning anterolateral perforator flap for free transplantation, included 13 males and 7 females, aged from 22 to 58 years old with an average of (36.45±12.36) years old. The size of flap ranged from 8.0 cm×5.0 cm to 20.0 cm×12.0 cm. Before operation, perforating vessels on the anterolateral thigh region were detected and marked with a portable Doppler detector. For the defect width less than 8 cm, 11 patients were repaired with a single flap. For the defect width more than 8 cm, the wound could not be sutured directly, and the lobulated flap technique was used in 9 patients, the width was converted to length, and the donor site was closed directly. Under the microscope, all flaps were thinened in a stepwise manner from the center of the pedicle to the periphery. After operation, survival of the flap, the shape, texture, sensory function recovery were observes, and recovery of foot function was evaluated by Maryland foot function evaluation standard.
RESULTS:
All 20 patients with microsurgical thinned anterolateral thigh perforator flaps were survived. Venous crisis occurred in 1 patient due to subcutaneous hematoma, after removal of the hematoma, the crisis was relieved and the flap survived successfully. The wounds in the donor and recipient sites healed well, and only linear scars left in the donor sites. Twenty patients were followed up for 3 to 26 months after operation, good shape of flaps without bloated, and good texture. The two-point discrimination of free flaps ranged from 9.0 to 16.0 mm, and the protective sensation was restored. The ankle flexion and extension function recovered well and patients could walk normally. According to Maryland foot function evaluation standard, 8 patients got excellent result, 10 patients good and 2 middle.
CONCLUSION
Microsurgical thinned anterolateral thigh perforator flap is an ideal method to repair soft tissue defects in functional area of foot and ankle, with good appearance and texture of the flap, no need for re-plastic surgery, reduced hospitalization costs, and less donor site damage.

Journal of Environmental and Occupational Medicine 2023;40(10):1212-1217
Noise pollution has become a common public health problem. The harm of noise exposure to human health cannot be ignored. Exposure to noise not only damages the auditory system but also affects the non-auditory system. At present, accumulating domestic and international epidemiological studies have suggested that noise exposure may be related to glycolipid metabolism disturbance. This article summarized recent epidemiological evidence of the association between noise exposure and glucose and lipid metabolism disorders, such as type 2 diabetes, obesity, metabolic syndrome, and hyperlipidaemia. The potential biological mechanisms connecting noise exposure to glucolipid metabolism were also introduced, e.g. noise as a stressor, sleep disorders, and intestinal flora regulation. This study discussed the impacts of noise exposure on glycolipid metabolism related diseases, providing a basis for further identifying noise related risk factors, conducting future related research, and formulating scientific and effective prevention and control measures.

Journal of Southern Medical University 2023;43(4):527-536
OBJECTIVE:
To investigate the role of myosin heavy chain 9 (MYH9) in regulation of cell proliferation, apoptosis, and cisplatin sensitivity of non-small cell lung cancer (NSCLC).
METHODS:
Six NSCLC cell lines (A549, H1299, H1975, SPCA1, H322, and H460) and a normal bronchial epithelial cell line (16HBE) were examined for MYH9 expression using Western blotting. Immunohistochemical staining was used to detect MYH9 expression in a tissue microarray containing 49 NSCLC and 43 adjacent tissue specimens. MYH9 knockout cell models were established in H1299 and H1975 cells using CRISPR/Cas9 technology, and the changes in cell proliferation cell were assessed using cell counting kit-8 (CCK8) and clone formation assays; Western blotting and flow cytometry were used to detect apoptosis of the cell models, and cisplatin sensitivity of the cells was evaluated using IC50 assay. The growth of tumor xenografts derived from NSCLC with or without MYH9 knockout was observed in nude mice.
RESULTS:
MYH9 expression was significantly upregulated in NSCLC (P < 0.001), and the patients with high MYH9 expression had a significantly shorter survival time (P=0.023). In cultured NSCLC cells, MYH9 knockout obviously inhibited cell proliferation (P < 0.001), promoted cell apoptosis (P < 0.05), and increased their chemosensitivity of cisplatin. In the tumor-bearing mouse models, the NSCLC cells with MYH9 knockout showed a significantly lower growth rate (P < 0.05). Western blotting showed that MYH9 knockout inactivated the AKT/c- Myc axis (P < 0.05) to inhibit the expression of BCL2- like protein 1 (P < 0.05), promoted the expression of BH3- interacting domain death agonist and the apoptosis regulator BAX (P < 0.05), and activated apoptosis-related proteins caspase-3 and caspase-9 (P < 0.05).
CONCLUSION
High expression of MYH9 contributes to NSCLC progression by inhibiting cell apoptosis via activating the AKT/c-Myc axis.
