The development of traditional Chinese medicine (TCM) diagnosis and treatment has undergone multiple paradigms, evolving from sporadic experiential practices to systematic approaches in syndrome differentiation and treatment and further integration of disease and syndrome frameworks. TCM is a vital component of the medical system, valued alongside Western medicine. Treatment based on syndrome differentiation embodies both personalized treatment and holistic approaches; however, the inconsistency and lack of stability in syndrome differentiation limit clinical efficacy. The existing integration of diseases and syndromes primarily relies on patchwork and embedded systems, where the full advantages of synergy between Chinese and Western medicine are not fully realized. Recently, driven by the development of diagnosis and treatment concepts and advances in analytical technology, Western medicine has been rapidly transforming from a traditional biological model to a precision medicine model. TCM faces a similar need to progress beyond traditional syndrome differentiation and disease-syndrome integration toward a more precise diagnosis and treatment paradigm. Unlike the micro-level precision trend of Western medicine, precision diagnosis and treatment in TCM is primarily reflected in data-driven applications that incorporate information at various levels, including precise syndrome differentiation, medication, disease management, and efficacy evaluation. The current priority is to accelerate the development of TCM precision diagnosis and treatment technology platforms and advance discipline construction in this area.

The pathological changes of myocardial infarction (MI) are mainly characterized by progressive myocardial ischemic necrosis, decline in cardiac diastolic function, thinning of the ventricular wall, and enlargement of the ventricles. The clinical manifestations include myocardial ischemia, heart failure, arrhythmia, shock, and even sudden cardiac death, rendering MI one of the most perilous cardiovascular diseases. Currently, the clinical treatment for MI primarily involves interventional procedures and drug therapy. However, due to their significant side effects and high complication rates associated with these treatments, they fail to ensure a satisfactory quality of life and long-term prognosis for patients. On the other hand, traditional Chinese medicine has demonstrated remarkable potential in improving patient prognosis while reducing side effects. Research has elucidated that various signaling pathways such as nuclear transcription factor-κB (NF-κB), adenosine 5̒-monophosphate-activated protein kinase (AMPK), transforming growth factor-β (TGF-β)/Smads, mitogen-activated protein kinase (MAPK), Wnt/β-catenin (β-catenin), and phosphatidylinositol 3-kinase (PI3K)/protein kinase B(Akt) play crucial roles in regulating the occurrence and development of MI. Effectively modulating these signaling pathways through its therapeutic interventions, traditional Chinese medicine can enhance MI management by inhibiting apoptosis, providing anti-inflammatory properties, alleviating oxidative stress levels, and resisting myocardial ischemia. Due to its notable efficacy and favorable safety, it has become an area of focus in clinical practice.

BACKGROUND:Carnosic acid,a bioactive compound found in rosemary,has been shown to reduce inflammation and reactive oxygen species(ROS).However,its mechanism of action in osteoclast differentiation remains unclear. OBJECTIVE:To investigate the effects of carnosic acid on osteoclast activation,ROS production,and mitochondrial function. METHODS:Primary bone marrow-derived macrophages from mice were extracted and cultured in vitro.Different concentrations of carnosic acid(0,10,15,20,25 and 30 μmol/L)were tested for their effects on bone marrow-derived macrophage proliferation and toxicity using the cell counting kit-8 cell viability assay to determine a safe concentration.Bone marrow-derived macrophages were cultured in graded concentrations and induced by receptor activator of nuclear factor-κB ligand for osteoclast differentiation for 5-7 days.The effects of carnosic acid on osteoclast differentiation and function were then observed through tartrate-resistant acid phosphatase staining,F-actin staining,H2DCFDA probe and mitochondrial ROS,and Mito-Tracker fluorescence detection.Western blot and RT-PCR assays were subsequently conducted to examine the effects of carnosic acid on the upstream and downstream proteins of the receptor activator of nuclear factor-κB ligand-induced MAPK signaling pathway. RESULTS AND CONCLUSION:Tartrate-resistant acid phosphatase staining and F-actin staining showed that carnosic acid dose-dependently inhibited in vitro osteoclast differentiation and actin ring formation in the cell cytoskeleton,with the highest inhibitory effect observed in the high concentration group(30 μmol/L).Carnosic acid exhibited the most significant inhibitory effect during the early stages(days 1-3)of osteoclast differentiation compared to other intervention periods.Fluorescence imaging using the H2DCFDA probe,mitochondrial ROS,and Mito-Tracker demonstrated that carnosic acid inhibited cellular and mitochondrial ROS production while reducing mitochondrial membrane potential,thereby influencing mitochondrial function.The results of western blot and RT-PCR revealed that carnosic acid could suppress the expression of NFATc1,CTSK,MMP9,and C-fos proteins associated with osteoclast differentiation,and downregulate the expression of NFATc1,Atp6vod2,ACP5,CTSK,and C-fos genes related to osteoclast differentiation.Furthermore,carnosic acid enhanced the expression of antioxidant enzyme proteins and reduced the generation of ROS during the process of osteoclast differentiation.Overall,carnosic acid exerts its inhibitory effects on osteoclast differentiation by inhibiting the phosphorylation modification of the P38/ERK/JNK protein and activating the MAPK signaling pathway in bone marrow-derived macrophages.

The concept of holism is the core idea of traditional Chinese medicine (TCM). Various organs and tissues coordinate with each other to maintain the body's life activities, with a close and mutual influence between the spleen, stomach, and the central nervous system (brain). The gut-brain axis plays an important bridging role between the digestive system and the central nervous system, achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence, coordination, and integration between different organs and systems; multimodality, on the other hand, utilizes multiple sensory modalities, such as vision, hearing, and touch, to convey information. By combining TCM theory with the gut-brain axis theory, a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders, precancerous gastrointestinal diseases, Alzheimer's disease, Parkinson's syndrome, type 2 diabetes, and depression.

China Occupational Medicine 2025;52(1):1-9
The worksite survey of occupational disease diagnosis is a series of occupational health investigations in the workplace initiated by the occupational disease diagnosis institution or the public health administrative department in order to understand whether there is a causal relationship between the workers' diseases and the workplace in the process of occupational disease diagnosis and verification. The main purpose of the worksite survey is to find out whether there are occupational hazards that cause health damage to workers in the workplace, and to analyze whether there is a causal relationship between the exposure to occupational hazards at the corresponding concentration (intensity) and the diseases suffered by workers. In actual work, it is necessary to determine whether it is necessary to organize worksite survey according to the legal situation and actual work of occupational disease diagnosis. The mainly works of worksite survey includes three aspects: preliminary preparation, survey implementation and survey report writing. It is necessary to pay attention to the key and difficult tasks such as preparation before survey, survey plan and questionnaire, complexity and uncertainty of worksite survey and sampling and detection of occupational hazard factors in workplace. After the worksite survey,it is necessary to write a written occupational disease on-site investigation report to provide objective, reliable and scientific evidence for occupational disease diagnosis.

OBJECTIVE To investigate the effect and mechanism of Astragalus polysaccharide (APS) on peritoneal fibrosis and angiogenesis in rats with peritoneal dialysis (PD). METHODS Rats were randomly divided into normal control group (Control group), model group (PD group), 70 mg/kg APS group (APS-L group), 140 mg/kg APS group (APS-H group), and 140 mg/kg APS+40 mg/kg hypoxia-inducible factor-1α (HIF-1α) agonist DMOG group (APS-H+DMOG group), with 12 rats in each group. PD rat models were constructed in the last four groups of rats. Administration groups were given APS intragastrically and DMOG intraperitoneally. Control group and PD group were given constant volume of normal saline intragastrically, once a day, for 4 consecutive weeks. After the last medication, the peritoneal ultrafiltration (UF), mass transfer of glucose (MTG), the levels of serum creatinine (Scr) and blood urea nitrogen (BUN) were detected in rats; peritoneal histomorphology and peritoneal fibrosis (peritoneal thickness and proportion of collagen fiber deposition) were observed; the microvascular density and the expression levels of α-smooth muscle actin (α-SMA), laminin (LN), HIF-1α and vascular endothelial growth factor (VEGF) proteins were detected in peritoneal tissue of rats. RESULTS Compared with Control group, the mesothelium of rats in the PD group was loosely arranged and shed, inflammatory cells infiltrated, the peritoneal thickness and proportion of collagen fiber deposition were increased significantly (P<0.05). The levels of MTG, Scr and BUN in serum, microvascular density and the expressions of α-SMA, LN, HIF-1α and VEGF proteins were significantly increased, while the level of UF was significantly decreased (P< 0.05); compared with PD group, the levels of above indexes were significantly reversed in APS-L and APS-H groups (P<0.05), and the improvement of APS-H group was better than APS-L group (P<0.05). Compared with APS-H group, the levels of above indexes in APS-H+DMOG group were all reversed (P<0.05). CONCLUSIONS APS inhibits peritoneal fibrosis and angioge-nesis in PD rats by inhibiting HIF-1α/VEGF signaling pathway.

A major impedance to neuronal regeneration after peripheral nerve injury(PNI)is the activation of various programmed cell death mechanisms in the dorsal root ganglion.Ferroptosis is a form of pro-grammed cell death distinguished by imbalance in iron and thiol metabolism,leading to lethal lipid peroxidation.However,the molecular mechanisms of ferroptosis in the context of PNI and nerve regeneration remain unclear.Ferroportin(Fpn),the only known mammalian nonheme iron export protein,plays a pivotal part in inhibiting ferroptosis by maintaining intracellular iron homeostasis.Here,we explored in vitro and in vivo the involvement of Fpn in neuronal ferroptosis.We first delineated that reactive oxygen species at the injury site induces neuronal ferroptosis by increasing intracellular iron via accelerated UBA52-driven ubiquitination and degradation of Fpn,and stimulation of lipid peroxidation.Early administration of the potent arterial vasodilator,hydralazine(HYD),decreases the ubiquitination of Fpn after PNI by binding to UBA52,leading to suppression of neuronal cell death and significant ac-celeration of axon regeneration and motor function recovery.HYD targeting of ferroptosis is a promising strategy for clinical management of PNI.
