Lung cancer, with persistently high incidence and mortality rates, remains a significant global health challenge. By taking the study on the experience in diagnosis and treatment of lung cancer with phlegm-dampness and blood stasis syndrome by distinguished traditional Chinese medicine physicians of the Sichuan School as an example, the diagnosis and treatment system for lung cancer with phlegm-dampness and blood stasis syndrome, which was formed in response to the humid and foggy environment of the Sichuan Basin, possesses unique value. However, traditional inheritance modes face challenges such as fragmentation, lack of standardization, and insufficient quantification, which hinder the promotion and application of this experience. This research focused on how to leverage multimodal data and artificial intelligence-generated content (AIGC) to achieve precise analysis, intelligent inheritance, and clinical innovation of the experience in diagnosis and treatment of lung cancer with phlegm-dampness and blood stasis syndrome by distinguished traditional Chinese medicine physicians of the Sichuan School. By integrating multimodal data (encompassing four diagnostic methods of traditional Chinese medicine, modern medical imaging, clinical laboratory tests, molecular biology, and regional environmental information), a precise diagnosis and treatment system integrating macro and micro perspectives for the "disease, syndrome, and pathogenesis" was constructed. The research yielded the following results: (1) In precise syndrome differentiation, the objective quantification of the phlegm-dampness and blood stasis syndrome was achieved. By constructing a "four diagnostic methods, imaging, and molecule" correlation model, the study revealed intrinsic links between tongue and pulse parameters and the tumor microenvironment, as well as between regional climatic factors and syndrome characteristics, enabling real-time dynamic monitoring of efficacy. (2) In elucidating patterns, the study systematically explored the syndrome differentiation thoughts of Sichuan School physicians, such as the timing of purgation and tonification. A "pathogenesis, syndrome complex, and prescriptions and herb" network model was constructed, which accurately elucidated the synergistic action mechanisms of core herb pairs and quantified the dynamic compatibility patterns of reinforcing healthy Qi and eliminating pathogenic factors. (3) In intelligent empowerment, an auxiliary system integrating intelligent syndrome differentiation, treatment plan generation, and efficacy evaluation was built. This system can fuse regional characteristics with individual data, dynamically generate and optimize personalized prescriptions aligned with the experience of Sichuan School, and predict efficacy trends and potential adverse reactions. The integration of multimodal data and AIGC can effectively facilitate the structured inheritance and clinical translation of distinguished physicians' experience. The established intelligent diagnosis and treatment model integrating traditional Chinese medicine and Western medicine demonstrates clear potential in prolonging patients' progression-free survival, alleviating symptoms, and reducing adverse reactions to treatment. This study provides a referential methodological framework for the traditional Chinese medicine experience in diagnosis and treatment of lung cancer, especially the empirical inheritance and modernized development of regional academic schools. It contributes to advancing clinical diagnosis and treatment toward greater precision and personalization.

ObjectiveThe Golgi apparatus serves as a central hub in the eukaryotic secretory pathway, responsible for the processing, sorting, and trafficking of proteins and lipids. In mammalian cells, the Golgi typically forms a perinuclear ribbon-like structure composed of laterally connected cisternae stacks.The maintenance of Golgi ribbon structure depends on the balance of membrane flux across multiple intracellular trafficking pathways, yet the specific contributions of distinct trafficking branches to Golgi macroscopic morphology remain elusive. In mammalian cells, the Golgi ribbon is typically organized as a perinuclear, laterally connected structure composed of stacked cisternae, and its integrity is highly dynamic and sensitive to perturbations in membrane trafficking. This study aims to elucidate the role of coat protein complex I (COPI)-mediated retrograde transport in maintaining the Golgi ribbon and to dissect the functional relationship between the transmembrane cargo receptors LEPROT/LEPROTL1 (LEPROTs) and the COPI adaptor GOLPH3. MethodsUsing siRNA interference and gene-deficient cell lines, we selectively perturbed COPI- or adaptor protein complex 1 (AP-1)-mediated trafficking pathways in HeLa cells. To quantitatively evaluate Golgi morphology, we employed a “Golgi Angle”-based measurement to assess its circumferential distribution around the nucleus. The spatial distribution of the Golgi ribbon was quantitatively analyzed using confocal microscopy, while Golgi ultrastructure and vesicle density were examined via transmission electron microscopy. Additionally, the subcellular distribution of COPI components was assessed by immunofluorescence co-localization. ResultsSelective inhibition of COPI retrograde transport significantly induced the circumferential extension of the Golgi ribbon around the nucleus, whereas blocking AP-1-mediated anterograde transport resulted in Golgi compaction, indicating opposing roles. These results suggest that different trafficking branches downstream of ARF1 exert distinct and even antagonistic effects on Golgi morphology. LEPROTs-deficient cells exhibited a Golgi extension phenotype highly consistent with COPI impairment. Furthermore, knockdown of GOLPH3 in a LEPROTs double-knockout background produced a significant additive effect on Golgi extension, suggesting that LEPROTs and GOLPH3 play non-redundant roles in regulating COPI-related trafficking processes. Mechanistically, loss of either LEPROTs or GOLPH3 led to the aberrant accumulation of COPI components at endoplasmic reticulum exit sites, accompanied by a reduction in COPI-like vesicles around the Golgi. This redistribution indicates a defect in COPI recycling between the ER-Golgi interface and the Golgi apparatus. Ultrastructural analysis revealed that Golgi cisternae in defective cells became shorter and thicker while maintaining a stable number of stacks. In parallel, the density of Golgi-associated vesicles was markedly decreased, further supporting an impairment in COPI vesicle formation or budding processes. ConclusionThis study demonstrates that active COPI retrograde transport is a critical factor in restricting the over-connection of the Golgi ribbon and maintaining its compactness. Rather than causing fragmentation, partial disruption of COPI function leads to a distinct morphological outcome characterized by Golgi ribbon extension at the light microscopy level and cisternal remodeling at the ultrastructural level. LEPROTs and GOLPH3 cooperatively promote the recycling and vesiculation of COPI components, thereby imposing a structural constraint on the Golgi periphery. Our findings support a model in which multiple adaptor proteins act in parallel to sustain efficient COPI cycling, thereby maintaining Golgi structural homeostasis. These findings provide new cell biological evidence for the membrane trafficking basis of Golgi morphological homeostasis.

With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

ObjectiveMigraine is a leading neurological disorder and the fourth most common cause of years lived with disability worldwide, affecting nearly 116 million individuals. Although pharmacological treatments are available, their efficacy is often limited by side effects and variable response rates. Repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (DLPFC) offers a safe, non-invasive alternative for migraine management. However, the neurophysiological mechanisms, particularly how rTMS modulates local cortical excitability and distributed pain-related circuits, remain poorly understood. Elucidating these mechanisms is essential for optimizing treatment protocols and improving clinical outcomes. MethodsThis study employed concurrent transcranial magnetic stimulation and electroencephalography (TMS-EEG) to investigate neuroplastic and neurocircuitry mechanisms of DLPFC-rTMS in migraine. Study 1 compared 30 migraineurs and 28 healthy controls to identify abnormalities in TMS-evoked potentials (TEPs) and significant current density (SCD) within sensory-discriminative regions including the primary somatosensory cortex (S1) and posterior insula (pINS), cognitive-affective regions including the anterior insula (aINS) and midcingulate cortex (MCC), and a descending modulatory region, the periaqueductal gray (PAG). Study 2 used a single-blind, crossover, sham-controlled design in 34 healthy participants. Each participant received both active (10 Hz, 80% RMT, 1 500 pulses) and sham DLPFC-rTMS in counterbalanced order. TMS-EEG and cold pain tolerance were assessed before and after each session. ResultsIn Study 1, migraineurs showed a significantly less negative N120 amplitude compared to healthy controls (P=0.027, Cohen’s d=0.60), indicating local intracortical disinhibition. No group differences were observed for N40, P60, or P180 components. At the source level, migraineurs exhibited significantly higher SCD in the S1, pINS, aINS, and MCC (allQ<0.05), but not in the ventroposterior thalamus (vpTHAL), mediodorsal thalamus (mdTHAL), or PAG. In Study 2, active rTMS significantly reduced SCD from pre- to post-stimulation in the S1, aINS, and MCC (all Q<0.05). Sham stimulation also reduced SCD in the S1 (Q<0.05) but not in the aINS or MCC. Although no significant group-level analgesic effect was observed between active and sham conditions (P=0.107), correlation analyses revealed that greater SCD reductions in the S1 and MCC were significantly associated with higher post-rTMS pain tolerance (R=-0.487 and -0.495, both Q<0.01) and larger improvements in pain tolerance(R=-0.487 and -0.451, both Q<0.05). No such correlations were found following sham stimulation, suggesting that the behavioural relevance of neural changes is specific to active rTMS. ConclusionThis study provides novel evidence that migraineurs exhibit both local neuroplastic abnormalities (reduced N120 amplitude) and hyperactivity in key pain-processing regions (S1, pINS, aINS, MCC). A single session of DLPFC-rTMS reduced hyperactivity in the aINS, MCC, and S1. Notably, greater reductions in the S1 and MCC were associated with improved pain tolerance. These findings identify distinct cortical circuitries, particularly within the cognitive-affective pain network, that may serve as potential biomarkers for optimizing rTMS treatment in migraine and other chronic pain conditions. Future studies should validate these results in patient populations experiencing spontaneous migraine attacks and explore multi-session or accelerated rTMS protocols.

OBJECTIVE To mine the risk signals associated with erectile dysfunction (ED) related to antihypertensive drugs based on real-world data, and to provide a reference for the safe clinical use and risk monitoring of these drugs.METHODS Reports of ED associated with 15 target antihypertensive drugs were extracted from the US FDA Adverse Event Reporting System (FAERS) database, covering the period from the first quarter of 2004 to the first quarter of 2026. Three proportional disproportionality measures (reporting odds ratio, proportional reporting ratio, and empirical Bayesian geometric mean) were used to mine the risk signals for ED associated with various antihypertensive drugs, and stratified analyses were performed based on patient age and body weight.RESULTS A total of 997 ED reports associated with 15 antihypertensive drugs were included. The majority were male patients (931 reports), with age concentrated in the 18 to <65 years group (511 reports), body weight in the 50 to <100 kg group (366 reports), and reporters predominantly consumers/patients (497 reports). The top three drugs by number of reports were amlodipine (413 reports), metoprolol (133 reports), and valsartan (82 reports); the overall demographic distribution characteristics of reports associated with each drug were similar. Positive signals were detected for 8 drugs, including amlodipine and metoprolol. ED associated with atenolol, candesartan, metoprolol, hydrochlorothiazide, and losartan mostly occurred within 30 days after medication; ED associated with valsartan and perindopril mostly occurred over 360 days after medication; and the onset time of amlodipine-associated ED was evenly distributed across all time periods. There were a total of 835 serious reports, with calcium channel blockers (CCBs) accounting for the highest proportion (44.0%) and angiotensin-converting enzyme inhibitors for the lowest (3.7%). The intensity of risk signals for amlodipine-associated ED increased with advancing age and higher body weight, while the signals for metoprolol were most pronounced in individuals aged 45 to <60 years and weighing≥100 kg; positive signals for valsartan were observed only in individuals aged≥60 years and those weighing 50 to <75 kg or ≥100 kg.CONCLUSIONS Reports of ED associated with antihypertensive drugs exhibit significant heterogeneity across drug types and differences in the distribution of onset times; CCBs have the highest proportion of serious reports; and the relationship between ED risk signals associated with amlodipine, metoprolol, and valsartan and age and body weight also shows marked heterogeneity.

ObjectiveTo investigate the contamination status of arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) in commercially available aquatic products in Shanghai and their distribution characteristics among different categories of aquatic products, and to assess the dietary exposure levels and non‑carcinogenic health risks of As, Cd, Pb, and Hg through aquatic product consumption among different age groups, so as to provide a scientific basis for food safety surveillance of aquatic products and dietary risk management for residents in Shanghai. MethodsFrom October to November 2021, a total of 90 aquatic product samples, including marine fish, freshwater fish, freshwater shrimp, marine crab, freshwater crab, and mollusks, were randomly collected from 16 districts of Shanghai. Sample pretreatment was performed according to GB 5009.268‒2016 (National Food Safety Standard—Determination of Multi‑elements in Foods). The concentrations of As, Cd, and Pb in aquatic products were determined by inductively coupled plasma mass spectrometry (ICP‑MS), and Hg was determined by direct mercury analyzer. Inorganic arsenic (iAs) was estimated as 3.5% of total As according to the method recommended by the European Food Safety Authority (EFSA). The contamination levels of As, Cd, Pb, and Hg in aquatic products were evaluated according to GB 2762‒2017 (National Food Safety Standard—Maximum Levels of Contaminants in Foods). A combined approach of point assessment and probabilistic assessment was applied to estimate the estimated daily intake (EDI) and non‑carcinogenic risk indicators—hazard quotient (HQ) and hazard index (HI)—for different age groups. ResultsThe detection rates of As and Hg were both 100.00% in all samples, while those of Cd and Pb were 74.44% and 25.56%, respectively. The arithmetic means (wet weight) of the four elements and estimated iAs were: As (1.432 9±3.736 5) mg·kg-1, iAs (0.050 2±0.130 8) mg·kg-1, Cd (0.082 5±0.197 8) mg·kg-1, Pb (0.006 1±0.005 5) mg·kg-1, and Hg (0.021 9±0.016 7) mg·kg-1. According to the relevant maximum residue limits, 2 out of 7 mollusk samples (28.57%) and 3 out of 20 marine fish samples (15.00%) exceeded the limit for iAs, and 2 out of 8 marine crab samples (25.00%) exceeded the limit for Cd. The estimated daily intake (EDI, μg·kg-1·d-1, by body weight) of iAs, Cd, Pb, and Hg via aquatic product consumption varied among different age groups, with the highest levels observed in children aged 3‒4 years, decreasing gradually with age to the lowest level at 12 ‒ <15 years, with a slight rebound thereafter. The point assessment results showed that the HQs of iAs, Cd, Pb, and Hg ranged from 0 to 0.25, and the cumulative HI ranged from 0.27 to 0.48, all below 1, indicating a relatively low overall risk. The probabilistic assessment results revealed that under the high‑exposure scenario (P97.5), the HQs of iAs (1.101‒1.281) and Cd (1.175‒1.366) exceeded 1 in children aged 3‒9 years, suggesting potential health risks, while the HQs of Pb and Hg were all below 1, indicating relatively lower risks. ConclusionHg and As are ubiquitously detected in commercially available aquatic products in Shanghai, while the detection rates of Cd and Pb are relatively low. The overall non-carcinogenic risk is at an acceptable level, but children aged 3‒9 years may have potential health risks from iAs and Cd under high-percentile exposure levels. It is recommended to strengthen the monitoring of toxic elements in key aquatic products such as marine fish, mollusks, and marine crabs, and to implement targeted dietary risk management measures for sensitive populations, including children.

ObjectiveStroke remains the leading cause of acquired disability in adults worldwide, imposing a substantial socioeconomic burden on patients, families, and healthcare systems. Among the various neurological deficits caused by stroke, motor dysfunction——particularly contralateral hemiplegia——is the most common and debilitating consequence, and it predominantly results from damage to the cortical motor conduction pathways. When motor cortex neurons or their projecting fibers are damaged, the distal axons and their associated myelin sheaths undergo a series of progressive, programmed degeneration, fragmentation, and eventual phagocytic clearance. This pathological process is termed Wallerian degeneration (WD). However, the temporal progression of WD following ischemic stroke and the associated alterations in the local glial microenvironment remain incompletely understood. The present study was designed to systematically elucidate the time course of corticospinal tract (CST) axonal WD after ischemic stroke in mice, and to simultaneously characterize the dynamic pathological changes of astrocytes, microglia, oligodendrocyte lineage cells, and myelinating oligodendrocytes during the WD process. MethodsEight-week-old male C57BL/6J mice were randomly assigned to control and ischemic stroke groups. A focal cortical ischemic stroke model was established in the right sensorimotor cortex using the photothrombotic method. This method induces localized intravascular thrombosis in the target cortical region through precisely controlled interaction between the photosensitizer and laser light of specific wavelength. At day 1 post‑surgery, 2,3,5-triphenyltetrazolium chloride (TTC) staining was performed to evaluate infarct volume, hematoxylin and eosin (HE) staining for histopathological examination, and Nissl staining for assessment of neuronal injury. For axonal degeneration time-course analysis, rAAV-CAG-mCherry anterograde viral tracing was employed to specifically label CST neurons. Cervical spinal cord sections at the CST region were collected at day 3, 5, 7, 14, and 60 post-injury. Morphological changes of mCherry-positive CST fibers were observed under fluorescence microscopy, and the fluorescence signal area fraction within the defined region was quantitatively analyzed to evaluate the dynamic process of axonal degeneration. For glial response assessment, immunofluorescence staining against Iba1 (microglia), GFAP (astrocytes), Olig2 (oligodendrocyte lineage cells), and APC (myelinating oligodendrocytes) was performed at day 7, 14, and 60 post‑surgery. The numbers of positive cells were counted to quantitatively analyze the dynamic changes in each glial population at different time points after ischemia, thereby revealing the evolution of the glial microenvironment during WD. ResultsThe photothrombotic method stably and reliably established an ischemic brain injury model confined to the sensorimotor cortex. Viral tracing revealed that the proportion of mCherry‑positive CST fibers was significantly reduced at day 7 after ischemic injury to the neuronal soma. Immunofluorescence staining demonstrated that during WD, the numbers of microglia and astrocytes in the CST region were significantly increased, whereas the numbers of oligodendrocyte lineage cells and myelinating oligodendrocytes showed no significant changes. ConclusionWD of CST axons is observed at day 7 post-ischemic stroke in a delayed manner. This degenerative process selectively activates microglia and astrocytes, while leaving the number of oligodendrocyte lineage cells largely unaffected.

ObjectiveTo investigate the distribution and characteristics of traditional Chinese medicine (TCM) syndromes in patients with colorectal cancer and metabolic dysfunction-associated fatty liver disease (CRC-MAFLD), to explore the correlation between influencing factors and syndrome distribution, and to provide a reference for clinical syndrome differentiation. MethodsA total of 319 patients who were admitted to Shanxi Provincial Institute of Traditional Chinese Medicine and The Affiliated Hospital of Shanxi University of Chinese Medicine from January 2021 to December 2025 and were diagnosed with CRC-MAFLD based on pathology and radiological examination were enrolled as subjects, and TCM syndrome differentiation was performed for all subjects. A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between multiple groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between multiple groups. The indicators with statistical significance in the univariate analysis were incorporated into the unordered multinomial Logistic regression model, and the syndrome of liver depression and spleen deficiency was set as the reference group to identify the independent influencing factors for each TCM syndrome. ResultsThe main clinical symptoms of CRC-MAFLD included fatigue (78.06%), abdominal distension (64.26%), poor appetite (61.13%), loose stool (57.05%), and costal pain (52.04%). The syndrome of liver depression and spleen deficiency showed the highest distribution frequency, followed by intermingled phlegm and blood stasis, internal retention of dampness turbidity, damp-heat accumulation, deficiency of liver and kidney, and deficiency of spleen and kidney. Comparison between groups with different TCM syndromes showed significant differences in the distribution of body mass index (χ2=42.216, P<0.001), the clinical stage of colorectal cancer (χ2=11.666, P=0.040), liver metastasis (χ2=19.279, P=0.002), degree of hepatic steatosis (χ2=71.085, P<0.001), diabetes (χ2=12.486, P=0.029), chemotherapy (χ2=21.920, P<0.001), fasting plasma glucose (FPG) (F=10.367, P<0.001), glycosylated hemoglobin (HbA1c) (F=3.696, P=0.003), albumin (Alb) (F=3.302, P=0.006), alkaline phosphatase (ALP) (H=34.350, P<0.001), gamma-glutamyl transferase (GGT) (H=41.679, P<0.001), and triglyceride (TG) (H=28.826, P<0.001). An unordered multinomial Logistic regression model was constructed with the syndrome of liver depression and spleen deficiency as the reference, and the results showed that overweight/obesity was a common independent risk factor for intermingled phlegm and blood stasis (odds ratio [OR]=4.468, P=0.002), internal retention of dampness turbidity (OR=2.944, P=0.024), and damp-heat accumulation (OR=5.651, P=0.001); clinical stage Ⅳ was an independent risk factor for deficiency of liver and kidney (OR=6.746, P=0.003) and deficiency of spleen and kidney (OR=10.074, P=0.001); presence of liver metastasis was an independent risk factor for intermingled phlegm and blood stasis (OR=5.145, P=0.001); severe fatty liver disease was an independent risk factor for intermingled phlegm and blood stasis (OR=5.201, P=0.007) and internal retention of dampness turbidity (OR=7.412, P=0.001), and moderate fatty liver disease was an independent risk factor for intermingled phlegm and blood stasis (OR=2.643, P=0.045), internal retention of dampness turbidity (OR=3.182, P=0.029), and damp-heat accumulation (OR=3.073, P=0.036); diabetes was an independent risk factor for internal retention of dampness turbidity (OR=5.133, P=0.003) and damp-heat accumulation (OR=3.716, P=0.031). As for continuous variables, elevated FPG was an independent risk factor for internal retention of dampness turbidity (OR=2.375, P=0.003) and damp-heat accumulation (OR=2.701, P=0.005); elevated HbA1c was an independent risk factor for intermingled phlegm and blood stasis (OR=2.029, P=0.032) and deficiency of liver and kidney (OR=3.308, P=0.010); elevated ALP was an independent risk factor for damp-heat accumulation (OR=1.053, P=0.019); elevated GGT was an independent risk factor for intermingled phlegm and blood stasis (OR=1.029, P=0.026) and damp-heat accumulation (OR=1.030, P=0.047); elevated TG was an independent risk factor for intermingled phlegm and blood stasis (OR=2.931, P=0.006) and internal retention of dampness turbidity (OR=2.449, P=0.019); elevated Alb was a protective factor against deficiency of spleen and kidney (OR=0.756, P=0.005). ConclusionBody mass index, the clinical stage of colorectal cancer, liver metastasis, degree of hepatic steatosis, diabetes, chemotherapy, FPG, HbA1c, Alb, ALP, GGT, and TG are the main influencing factors for TCM syndromes in CRC-MAFLD.

Objective:
To investigate the availability and use of child safety seats among children aged 0-3 years, so as to provide the basis for improving riding safety for children.
Methods:
Parents of children aged 0-3 years in Huangpu District, Shanghai Municipality, were recruited using the stratified multistage random sampling method from May to July 2024. Demographic information, family travel patterns, the use of child safety seat and related health beliefs were collected using questionnaire surveys. Factors affecting the use of child safety seats were identified using a multivariable logistic regression model.
Results:
Totally 514 valid questionnaires were recovered, with an effective rate of 96.98%. The respondents included 122 fathers (23.74%) and 392 mothers (76.26%), with a median age of 34.00 (interquartile range, 5.00) years. There were 446 families equipping with child safety seats, accounting for 86.77%; and 169 families using child safety seats, accounting for 32.88%. Multivariable logistic regression analysis showed that the parents who had children aged >1-2 years (OR=0.597, 95%CI: 0.366-0.973), travelled 2-4 times per month (OR=0.359, 95%CI: 0.213-0.607) or once per month or less (OR=0.384, 95%CI: 0.202-0.729), and scored high in perceived barrier (OR=0.634, 95%CI: 0.486-0.827) were less likely to use child safety seats; the parents who had children with local household registration (OR=2.506, 95%CI: 1.356-4.633), travelled 5-<10 km (OR=1.887, 95%CI: 1.148-3.101) or ≥10 km (OR=2.319, 95%CI: 1.355-3.967), always wore seat belts (OR=2.342, 95%CI: 1.212-4.524), scored high in perceived susceptibility (OR=1.392, 95%CI: 1.091-1.778) and self-efficacy (OR=1.413, 95%CI: 1.156-1.727) were more likely to use child safety seats.
Conclusions
Equipping family cars with child safety seats and using them can prevent and reduce traffic injuries among children aged 0-3 years. It is recommended to strengthen publicity to promote the use of child safety seats.
