In recent years, repetitive transcranial magnetic stimulation (rTMS) has garnered significant attention as a therapeutic approach for sleep disorders in the elderly. However, the prevailing rTMS protocols are predominantly developed based on normative neurophysiological data derived from young adults and fail to incorporate individualized parameters tailored to the brain characteristics of the elderly. To address this gap, the consensus development group synthesized the latest evidence from 2010 to 2025 and established a standardized rTMS protocol specifically for elderly patients with sleep disorders. Adhering to the Appraisal of Guidelines for Research and Evaluation II (AGREE II) framework, systematically screened randomized controlled trials (RCTs) and systematic reviews regarding rTMS in the treatment of sleep disorders across various conditions. Meanwhile, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was employed to rigorously grade the quality of evidence and the strength of recommendations. This consensus guideline delineates precise rTMS protocols for the management of sleep disorders in the elderly, highlights the adjustment of stimulation intensity according to scalp-cortex distance recommends either MRI‑guided neuronavigation or the Beam F3/F4 heuristic approach for accurate target localization, thereby providing precise rTMS intervention protocol for sleep disorders in the elderly, aiming to enhance clinical efficacy while ensuring treatment safety.

ObjectiveTo investigate the contamination status of ochratoxin A (OTA) in commercially available food products in Shanghai, and to assess OTA exposure levels and the associated non-carcinogenic and carcinogenic risks among pregnant women by integrating dietary consumption data of this population. MethodsThe levels of OTA contamination in 1 520 food samples collected in Shanghai from 2022 to 2023 were determined using liquid chromatography-tandem mass spectrometry. An exposure assessment model was developed based on the dietary consumption levels of pregnant women from the 2016‒2017 Shanghai Pregnant Women Dietary Monitoring Survey to calculate the estimated daily intake (EDI) of OTA, the margin of exposure for non-carcinogenic toxicity (MOE1), and the margin of exposure for carcinogenic toxicity (MOE2). An MOE1 greater than 200 and an MOE2 greater than 10 000 indicate that the non-carcinogenic toxicity and carcinogenic toxicity resulting from exposure are negligible, respectively. For samples with OTA contamination levels below the limit of detection (LOD), which accounted for more than 80% of the samples, the OTA levels were assigned values of 0 and LOD, respectively, for subsequent calculations. ResultsThe detection rates of OTA in cereals, nuts, dried fruits, and alcohol samples collected in 2022 were 2.03%, 0, 0, and 0, respectively. The OTA detection rates in cereals, nuts, dried fruits, beans, and alcohol samples collected in 2023 were 2.50%, 0.39%, 2.47%, 1.67%, and 13.33%, respectively. For pregnant women in Shanghai in 2022, simulation results indicated that when assigning a value of 0 and the LOD, theP50 values of EDI for dietary OTA exposure were 0.05 and 0.72 ng·(kg·d)-1, respectively, and the P95 values of EDI for dietary OTA exposure were 0.25 and 2.40 ng·(kg·d)-1, respectively. For pregnant women in Shanghai in 2023, the P50 values of EDI for dietary OTA exposure were 0.04 and 1.00 ng·(kg·d)-1, respectively, and the P95 values of EDI for dietary OTA exposure were 0.23 and 2.67 ng·(kg·d)-1, respectively, both substantially below the tolerable daily intake (TDI) for OTA [17 ng·(kg·d)-1]. The EDI for dietary OTA exposure in 100.0% of Shanghai pregnant women was lower than the TDI, indicating an overall low level of dietary OTA exposure among this population. For 100.0% of pregnant women, the MOE₁ for dietary OTA exposure exceeded 200. When assigned a value of 0, the MOE₂ for 100.0% of pregnant women in both 2022 and 2023 exceeded10 000. When assigned the LOD value, 72.3% and 81.8% of pregnant women in 2022 and 2023, respectively, had an MOE₂ exceeding 10 000. ConclusionFrom 2022 to 2023, samples of cereals, nuts, dried fruits, beans, and alcohol sold in Shanghai exhibited varying degrees of OTA contamination. The overall EDI of OTA exposure among pregnant women in Shanghai remained at a low level. The non-carcinogenic and carcinogenic risks associated with OTA exposure were generally low and at controllable levels.

Ferroptosis is a key driver of the onset and progression of chronic obstructive pulmonary disease (COPD). By exploring the role of ferroptosis in COPD from the perspective of "qi deficiency with retention and stagnation", it is considered that mitochondrial dysfunction and imbalanced antioxidant defenses are the microscopic manifestations of "qi deficiency", whereas iron accumulation and lipid peroxide deposition constitute the pathological basis of "retention and stagnation". In traditional Chinese medicine (TCM), the treatment principle is tonifying deficiency and benefiting qi, scattering retention and unblocking stagnation. Its mechanism involves improving the antioxidant system and mitochondrial function to enhance cellular resistance to ferroptosis, as well as relieving pulmonary iron overload, excessive lipid peroxidation, and inflammatory factor release to reduce the accumulation of pathological products, thereby exerting therapeutic effects on COPD.

Background Amid global climate change, extreme environmental events are occurring more frequently, and it is imperative to investigate the impacts of combined exposure to fine particluate matter (PM2.5) and cold spells (CS) on population mortality. Objective To analyze the association between sequential extreme PM2.5-cold spell (EP-CS) events and non-accidental mortality among residents in Zigong City from 2016 to 2021. Methods Using time-series study design, meteorological data in Zigong were collected from the Zigong Meteorological Bureau for the period from January 1, 2016 to December 31, 2021, while daily non-accidental mortality data were obtained from the mortality surveillance system of the Zigong Center for Disease Control and Prevention. We adopted the percentile method to define extreme PM2.5 events and cold spells. We analyzed the risk effect of EP-CS events on non-accidental mortality among residents in this city and explored the potential amplification of damage resulting from different patterns of consecutive extreme events by using distributed lag nonlinear model (DLNM). We also conducted stratified analyses based on age, gender, education level, and marital status. Results The EP-CS events demonstrated a significant impact on non-accidental mortality among the local residents, exhibiting a certain lagged effect. The effects on the overall residents lasted from lag0 (RR=1.030, 95%CI: 1.013, 1.048) to lag14 (RR=1.035, 95%CI: 1.019, 1.052). Notably, the effects were more pronounced among females, individuals aged 65 years and above, and those who were never married, divorced, or widowed. Different patterns of EP-CS events all associated with adverse effects, the health impact of EP-CS events was significantly greater than that of individual PM2.5 pollution or CS events. The analysis of lag effects across different event patterns revealed that the overall effect of EP-CS events with shorter intervals (0–7 d) had a stronger effect compared to EP-CS with longer intervals (8–14 d), and the RR values of lag14 were 1.034 (95%CI: 1.015, 1.054) and 1.017 (95%CI: 1.007, 1.027), suggesting that the damaging effect of compound events occurring in the short term was more significant. Conclusion All sequential extreme EP-CS events have an impact on non-accidental mortality among residents in this city, with compound events demonstrating a stronger effect. Females, individuals aged ≥65 years, and those who were never married, divorced, or widowed are more sensitive to EP-CS events.

OBJECTIVE To establish a scientific, systematic, multi-dimensional performance management system for pharmacy practice, so as to improve the efficiency and quality of pharmacy practice performance management in public hospitals. METHODS Based on the four dimensions of the balanced scorecard theory, finance, customer, internal process, learning and growth, reference indicators for pharmacy practice performance management were summarized. The Delphi method was used to screen indicators, and the analytic hierarchy process was applied to determine the weights of indicators. A pharmacy practice performance management system was then constructed. Based on this system, action plans were formulated and implemented. The effectiveness was evaluated from two aspects: customer reviews and changes in pharmacy practice outcomes. RESULTS A total of 28 reference indicators were summarized, and a performance management system for pharmacy practice was constructed, consisting of 4 primary indicators, 9 secondary indicators, and 20 tertiary indicators. Compared with action plans implementation before, the satisfaction of clinical departments was significantly improved, and 11 pharmacy practice performance management indicators were optimized after implementation. CONCLUSIONS A scientific and systematic performance management system for pharmacy practice has been successfully established, which can provide a reference for the innovation of hospital pharmacy practice management and the high quality development of pharmacy practice.

The chronicity of infectious diseases is an important field in the collaborative research of traditional Chinese and Western medicine. The warm disease theory of pathogen invading nutrient and blood aspects in traditional Chinese medicine (TCM) takes the struggle between healthy Qi and pathogenic Qi and cementation of Yin as the core pathogenesis, providing a unique theoretical framework for explaining the common pathology of infectious chronic diseases. This theory originated from Yin-Yang interaction in the Internal Classic and was enriched with WU Youke's theory of intruding pathogen interacting and lingering in blood vessels and YE Tianshi's theory of long-term illness entering collaterals. Combining the theory with modern medical knowledge, our team has condensed the dynamic pathogenesis model of deficiency (nutrient and blood aspects) and excess (pathogen) interacting in the blood collaterals of Yin aspect, the core feature of which is the four-dimensional interactions of cause (pathogen characteristics), location (three Yin locations of diseases), nature (deficiency and excess), and potential (transmission trend). The common pathology of infectious chronic diseases is reflected in interactions. That is, the interactions between nutrient and blood deficiency (immune exhaustion and metabolic disorder) and pathogen excess (pathogen persistence and fibrous hyperplasia) in the liver collaterals (Jueyin), kidney collaterals (Shaoyin), lung collaterals (Taiyin) and other blood collaterals of Yin aspect form the pathological damage characterized by immune inflammatory response-continuous tissue damage with excessive repair. Taking the inheritance and innovative development of classics as the main line, this paper systematically discusses the scientific connotation of the theory of pathogen invading nutrient and blood aspects and the paths of inheritance and innovation and clarifies the original significance of this theory in the chronic development of infectious diseases. Furthermore, taking clinical diseases as an example, this paper reflects the guiding value of this classical theory in the modern diagnosis and treatment of infectious diseases with integrated traditional Chinese and Western medicine and the application potential of this theory in solving complex medical problems through the construction of the innovative paradigm of precise diagnosis and treatment with integrated traditional Chinese and Western medicine.

Hepatocellular carcinoma (HCC), a malignancy with high mortality, exhibits poor survival rates and prognosis. The profound suppression of the tumor immune microenvironment (TIME) and the abnormal hyperactivity of metabolic reprogramming (MR) are the two primary factors driving HCC progression. Traditional Chinese medicine has demonstrated significant efficacy in HCC treatment. The team proposed that "deficiency of healthy Qi and stasis toxins" was the core pathogenesis of HCC, closely associated with TIME suppression and MR hyperactivity. This paper proposed that a suppressed state of the TIME was the biological manifestation of "deficiency of healthy Qi", where the functional exhaustion of effector T lymphocytes and natural killer cells reflected the decline of "healthy Qi" in eliminating pathogens. Conversely, the expansion and activation of immunosuppressive cells, such as regulatory T cells (Tregs), M2-like tumor-associated macrophages (TAM-M2), and myeloid-derived suppressor cells (MDSCs) , represent the dysfunction of "healthy Qi" in maintaining homeostasis. MR serves as the material basis of "stasis toxins". Stasis toxins exhibit heat stagnation, manifested by abnormal hyperactivity of glycolysis and lipid synthesis. They demonstrate migratory propensity, as toxic metabolites like lactic acid and prostaglandin E2 promote tumor invasion and metastasis. They display a consumptive nature, reflected in the functional suppression of immune cells. The vicious cycle between TIME and MR is the biopathological reflection of "deficiency of healthy Qi intertwined with stasis toxins". Immunosuppression exacerbates MR, while toxic metabolites further impair immune function, establishing a pathogenic chain of "deficiency leading to stasis, and stasis toxins damaging healthy Qi". The primary therapeutic approach is reinforcing healthy Qi, resolving stasis, and removing toxins, which can reinforce and tonify healthy Qi to regulate pathways, such as phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt), C-X-C chemokine receptor type 4/ C-X-C chemokine ligand 12 (CXCR4/CXCL12), and toll-like receptor 4/ nuclear factor-kappa B/ signal transducer and activator of transcription 3 (TLR4/NF-κB/STAT3), adjust T lymphocyte ratios, inhibit Tregs/TAM-M2 function, and downregulate immune checkpoints, including programmed death ligand 1/programmed death 1(PD-L1/PD-1), and reshape TIME. It is also involved in resolving stasis and removing toxins to modulate phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) and hypoxia-inducible factor-1α (HIF-1α) signaling pathways, suppress key enzymes in glycolysis and lipid synthesis, and block toxic metabolite production. Thus, this therapy synergistically regulates the immune and metabolic network, breaks the vicious cycle of "deficiency in healthy Qi and stasis toxins", and offers a novel strategy for integrating traditional Chinese medicine and Western medicine in HCC treatment.

ObjectiveBased on the regulation of macrophage M2 polarization, this study aims to explore the molecular mechanism and action targets of the Qijia Rougan prescription and its key effector ingredients in anti-fibrosis, thereby providing a basis and reference for the development of new drugs for hepatic fibrosis. MethodsA rat model of hepatic fibrosis was established by subcutaneous injection of 40%CCl4, followed by oral administration of Qijia Rougan granules. The volume of collagen fibers was detected using Masson staining, the fibrosis markers Collagen Ⅰ and α-SMA were detected using immunohistochemistry, the proportion of M2 macrophages was detected by flow cytometry. The expression levels of M2 macrophage phenotype markers CD163 and CD206 were detected using immunofluorescence double staining. Western blot was used to detect the levels of the transforming growth factor-β (TGF-β), platelet derived growth factor subunit B (PDGFB), interleukin-10 (IL-10), phosphorylated Janus kinase 1 (p-JAK1), and phosphorylated signal transducer and activator of transcription 6 (p-STAT6). Real-time fluorescent quantitative PCR was used to detect the relative expression levels of JAK1, STAT6, Arginase 1(Arg1), and Fizz1. Based on the theory of serum pharmacology, liquid chromatography-mass spectrometry and WENN analysis were used to obtain the active ingredients of Qijia Rougan prescription. Molecular docking and molecular dynamics simulation were performed to analyze the effector ingredients and their targets. The identified effector ingredients were interfered with IL-4-induced M2 polarization of RAW264.7 macrophage in vitro to validate the targets. ResultsQijia Rougan prescription significantly reduced the content of fibrosis markers α-SMA and Collagen Ⅰ, as well as collagen fiber content (P<0.05). It decreased the proportion of M2 macrophages and the levels of related cytokines IL-10, TGF-β and PDGFB, and up-regulated the levels of p-JAK1 and p-STAT6 (P<0.05). A total of 1 214 compounds were identified from Qijia Rougan prescription, medicated serum and blank serum, and 29 ingredients were finalized by Venn analysis, including 15 blood-entry prototypes and 14 drug metabolites. Molecular docking showed that enoxolone and berberine bound more strongly to JAK1, with binding free energies of -9.6 kcal·mol-1(1 cal≈4.184 J) and -9.1 kcal·mol-1, respectively. Molecular dynamics simulations showed that JAK1-enoxolone and JAK1-berberine exhibited stable simulation trajectories within 100 ns, with essentially identical conformations and high protein overlap before and after simulation. Their binding free energies were -25.18 5.0.81 kcal·mol-1 and -27.39 7.0.85 kcal·mol-1, respectively. The number of hydrogen bonds formed between JAK1 and enoxolone ranges from 0 to 5, and most of the time can be maintained at 2-3. In vitro intervention with enoxolone or berberine significantly reduced p-JAK1 and p-STAT6 levels (P<0.05). ConclusionQijia Rougan prescription inhibits M2 macrophage polarization in hepatic fibrosis. Enoxolone and berberine are the key effector ingredients of Qijia Rougan prescription to inhibit macrophage M2 polarization through targeting JAK1 and modulating the JAK1/STAT6 signaling pathway, thereby ameliorating hepatic fibrosis. This study provides a basis for prescription optimization, clinical application and new drug development, as well as a reference for monolithic anti-hepatic fibrosis research.
