ObjectiveTo conduct a comparative quality analysis of Inulae Flos， fuzz of Inulae Flos and calyx of Inulae Flos， elucidating the scientific connotation of the "removing calyx" process in the traditional processing of Inulae Flos. MethodsInulae Flos decoction pieces were collected， and the fuzz and calyx of Inulae Flos were prepared according to the experiences of old medicine workers. Subsequently， according to the methods under the "Inulae Flos" item in the 2025 edition of the Pharmacopoeia of the People's Republic of China， the appearance characteristics and thin-layer chromatography（TLC） identification of these samples were tested， and the moisture content， total ash content， extract content were also measured. The characteristic fingerprint patterns of Inulae Flos and fuzz of Inulae Flos were established by high-performance liquid chromatography（HPLC）， followed by similarity evaluation， principal component analysis（PCA）， and partial least squares-discriminant analysis（PLS-DA）. The contents of cryptochlorogenic acid， caffeic acid， 1，3-O-dicaffeoylqunic acid， 1，5-O-dicaffeoylqunic acid， and 1-O-acetyl britannilactone were determined to compare the quality differences of Inulae Flos， fuzz of Inulae Flos， and calyx of Inulae Flos. ResultsThe moisture content of Inulae Flos， fuzz of Inulae Flos， and calyx of Inulae Flos was all<10%. The determination results of total ash content were as follows：Calyx of Inulae Flos>Inulae Flos>fuzz of Inulae Flos， and the determination results of alcohol-soluble extract content were as follows：Fuzz of Inulae Flos>Inulae Flos>calyx of Inulae Flos. HPLC fingerprint patterns of Inulae Flos and fuzz of Inulae Flos were established， and 22 common peaks were identified. The similarity analysis and PCA showed that the overall quality of Inulae Flos and fuzz of Inulae Flos was similar， while the overall quality of calyx of Inulae Flos differed significantly from that of Inulae Flos and fuzz of Inulae Flos. PLS-DA results showed that Inulae Flos， fuzz of Inulae Flos， and calyx of Inulae Flos clustered into distinct groups， indicating significant differences among them. Cryptochlorogenic acid and caffeic acid had relatively high contents in calyx of Inulae Flos， the contents of 1，3-O-dicaffeoylqunic acid and 1，5-O-dicaffeoylqunic acid in Inulae Flos and fuzz of Inulae Flos were higher than those in calyx of Inulae Flos. The order of 1-O-acetyl britannilactone content was determined as follows：fuzz of Inulae Flos>Inulae Flos>calyx of Inulae Flos. ConclusionThe scientific nature of "Removing Calyx" process in the cleansing of Inulae Flos by old medicine workers is demonstrated by the resulting fuzz of Inulae Flos decoction pieces exhibiting enhanced cleanliness and higher content of the index component 1-O-acetyl britannilactone. This study provides a reference basis for further improving and enhancing the processing method and quality control standards of Inulae Flos.

Objective: To analyze the epidemiological characteristics and influencing factors of severe fever with thrombocytopenia syndrome (SFTS) in Zhejiang Province from 2019 to 2023, so as to provide the reference for strengthening SFTS prevention and control. Methods: Data on laboratory-confirmed SFTS cases in Zhejiang Province from 2019 to 2023 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Meteorological data, geographic environment and socioeconomic factors during the same period were collected from the fifth-generation European Centre for Medium-Range Weather Forecasts, Geospatial Data Cloud, and Zhejiang Statistical Yearbook, respectively. Descriptive epidemiological methods were used to analyze the epidemiological characteristics of SFTS from 2019 to 2023, and a Bayesian spatio-temporal model was constructed to analyze the influencing factors of SFTS incidence. Results: A total of 578 SFTS cases were reported in Zhejiang Province from 2019 to 2023, with an annual average incidence of 0.23/105. The peak period was from May to July, accounting for 52.60%. There were 309 males and 269 females, with a male-to-female ratio of 1.15∶1. The cases were mainly aged 50-<80 years, farmers, and in rural areas, accounting for 82.53%, 77.34%, and 75.43%, respectively. Taizhou City and Shaoxing City reported more SFTS cases, while Shaoxing City and Zhoushan City had higher annual average incidences of SFTS. The Bayesian spatio-temporal interaction model showed good goodness of fit. The results showed that mean temperature (RR=1.626, 95%CI: 1.111-2.378) and mean wind speed (RR=1.814, 95%CI: 1.321-2.492) were positively correlated with SFTS risk, while altitude (RR=0.432, 95%CI: 0.230-0.829) and population density (RR=0.443, 95%CI: 0.207-0.964) were negatively correlated with SFTS risk. Conclusions SFTS in Zhejiang Province peaks from May to July. Middle-aged and elderly people and farmers are high-risk populations. Taizhou City, Shaoxing City, and Zhoushan City are high-incidence areas. Mean temperature, mean wind speed, altitude, and population density can all affect the risk of SFTS incidence.

This paper systematically elaborates on the key points of diagnosis and differential diagnosis of salivary gland tumors characterized by a substantial amount of extracellular mucus as a main or prominent feature, and clarifies the core differential features. The term "mucus-rich" specifically denotes that mucus is a major component of the tumor, rather than a focal or minor one. This phenomenon is associated with distinct histogenetic mechanisms: it may result from specific genetic mutations (e.g., AKT1 E17K in mucinous adenocarcinoma) that drive ductal epithelial differentiation into mucus-secreting cells, or from myoepithelial cells secreting glycosaminoglycans that form a myxoid stroma. Salivary gland tumors with abundant extracellular mucus include mucinous cystadenoma, sialadenoma papilliferum-like intraductal papillary tumors, mucinous myoepithelioma, pleomorphic adenoma with mucin-rich stroma, mucinous adenocarcinoma, low-grade mucoepidermoid carcinoma, mucin-rich salivary duct carcinoma and intestinal-type adenocarcinoma. The diagnosis of these tumors is complicated by the dual nature of extracellular mucus: while it is a defining feature of some entities, it can also obscure key diagnostic architectural features in others, leading to histological overlap and inconspicuous diagnostic areas. Given the frequent histological morphological overlap among these tumors, immunohistochemical findings and molecular characteristics have emerged as crucial differential diagnostic criteria. Core differential diagnostic points include the following: histologically, there must be meticulous identification of typical structures obscured by mucin (such as squamoid cells in mucoepidermoid carcinoma and apocrine features in salivary duct carcinoma); in immunohistochemical staining, CK20 is useful for distinguishing intestinal-type adenocarcinoma (positive) from mucinous adenocarcinoma (negative), while androgen receptor aids in differentiating salivary duct carcinoma (positive) from mucoepidermoid carcinoma (negative); and molecular testing plays a critical role in definitive diagnosis (e.g., the AKT1 E17K mutation for mucinous adenocarcinoma, MAML2 rearrangement for mucoepidermoid carcinoma, and MEF2C::SS18 fusion for microsecretory adenocarcinoma). This paper systematically summarizes the core pathological features and differential diagnostic points of mucin-rich salivary gland tumors, aiming to provide a practical reference for clinical pathological diagnosis.

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.

Patients with lung cancer experience a heavy symptom burden during the perioperative period, which seriously affects their recovery and quality of life. Traditional symptom management models rely mainly on scheduled ward rounds during hospitalization and outpatient follow-up after discharge. However, they have limitations such as delayed symptom recognition, lack of post-discharge monitoring, and non-quantitative symptom assessment, which often lead to delayed interventions and low patient satisfaction. In recent years, the symptom management model based on electronic patient-reported outcomes (ePRO) has been increasingly valued in clinical practice. Existing high-level evidence from both domestic and international studies indicates that, through proactive monitoring, real-time alerts, and remote interventions, this model enables dynamic and continuous symptom management and helps improve patient recovery and healthcare experience. As a supplement to routine medical care, the ePRO-based symptom management model aims to enhance the quality of care rather than replace existing medical processes. To promote the standardized application of this model in perioperative lung cancer care, this consensus integrates domestic and international evidence. After multiple rounds of voting by more than 50 experts, it formulates 12 consensus statements covering the three core components, symptom monitoring, alerting, and intervention, to provide scientific and practical recommendations for clinical practice.

Objective To develop a symptom and function assessment scale for patients after Nuss procedure for pectus excavatum and to test its reliability and validity. Methods Following the principles and procedures of patient-reported outcome (PRO) scale development stipulated by the U.S. Food and Drug Administration, an initial draft was formed through literature analysis, qualitative interviews, and Delphi expert consultation. The preliminary draft was used to conduct a pre-survey on patients who underwent Nuss procedure for pectus excavatum at Guangdong Provincial People's Hospital, and the reliability and validity of the scale were tested. Results A preliminary PRO-based symptom and function scale was constructed, covering two domains: symptoms and impact on daily functions. The symptom dimension included six items: chest tightness, palpitations, pain, shortness of breath, foreign body sensation of the steel plate, and distress; while the impact on daily functions included four items: difficulty in getting out of bed or lying down, raising arms, bending over, and standing or sitting for a long time. A total of 73 patients who underwent Nuss procedure for pectus excavatum were included in the questionnaire survey, with 70 valid questionnaires collected, including 64 males and 6 females, with 56 patients aged 12-17 years and 14 patients ≥18 years. Through exploratory factor analysis, two common factors were extracted, with a cumulative variance contribution rate of 70%. The Cronbach’s α coefficient of the scale was 0.917. Conclusion The scale developed in this study has good reliability and validity, high reliability and stability, and can be used as an evaluation tool for the recovery status of patients after Nuss procedure for pectus excavatum.

OBJECTIVE To evaluate the cost-effectiveness of brivaracetam （BRV） versus perampanel （PER） as add-on therapy for drug-resistant focal epilepsy in adults from the perspective of the Chinese healthcare system.METHODS A Markov model was established to simulate the progression of drug-resistant focal epilepsy in adults， with a simulation cycle of 5 months， a time horizon of 44 years， and a discount rate of 4.5%. Clinical data required for the model were derived from the phase Ⅲ clinical trial of BRV and a post hoc analysis of PER； cost data and utility data were obtained from Yaozh and related literature. The willingness-to-pay （WTP） threshold was set at twice China’s 2025 per capita gross domestic product （GDP） [199 330 yuan per quality-adjusted life year （QALY）]， and a cost-effectiveness analysis was adopted to compare the cost-effectiveness of the regimens. One-way sensitivity analysis and probabilistic sensitivity analysis were performed to confirm the stability of the base-case analysis conclusions.RESULTS The incremental cost-effectiveness ratio （ICER） of BRV 50 mg/d as an add-on therapy versus PER 8 mg/d was 44 823.08 yuan/QALY， which was below the WTP threshold； the ICER of BRV 200 mg/d versus PER 12 mg/d was 238 783.00 yuan/QALY， which was above the WTP threshold. In the one-way sensitivity analysis， the direct medical cost of seizures ≥53 times/year and the health utility value of a seizure-free state per year had a relatively large impact on the two ICER results mentioned above， respectively. Probabilistic sensitivity analysis indicated that the above results were robust.CONCLUSIONS For the selection of add-on therapy for drug-resistant focal epilepsy in adults in China， when twice China’s per capita GDP is used as the WTP threshold， BRV 50 mg/d has a cost-effectiveness advantage over PER 8 mg/d， whereas BRV 200 mg/d not have a cost-effectiveness advantage over PER 12 mg/d.

ObjectiveTo investigate the protective effect of ellagic acid （EA） against bleomycin （BLM）-induced pulmonary fibrosis and associated pulmonary function impairment in mice， and to elucidate its relationship with the regulation of the interleukin（IL）-17/ nuclear factor （NF）-κB/ matrix metalloproteinase （MMP）9 signaling axis. MethodsA pulmonary fibrosis model was established in male C57BL/6J mice via intratracheal BLM injection. Interventions included IL-17 neutralizing antibody， Ixekizumab， SB-3CT， PDTC， or EA were used to modulate the IL-17/NF-κB/MMP9 signaling axis. Pathological changes in lung tissue were observed via HE， Masson， and Sirius red staining. Pulmonary function was assessed using a pulmonary function test （PFT）. Western blot and qRT-PCR were employed to detect related protein and gene expression. Network pharmacology was utilized to predict the potential targets of EA. A protein-protein interaction （PPI） network was constructed using the STRING database and Cytoscape. Molecular docking was performed to validate the binding capability of EA to core targets. ResultsBLM successfully induced obvious pulmonary fibrosis and lung dysfunction in mice， significantly elevating the level of the pro-inflammatory cytokine IL-17. This was associated with the activation of the transcription factor NF-κB p65， leading to the upregulation of the pro-fibrotic factor MMP9. Inhibition of the IL-17/NF-κB/MMP9 signaling axis markedly alleviated the degree of pulmonary fibrosis. EA intervention significantly suppressed the BLM-induced increase in IL-17， blocked the activation of the NF-κB/MMP9 pathway， and consequently reduced lung fibrotic lesions and improved pulmonary function. ConclusionEA may effectively ameliorate BLM-induced pulmonary fibrosis and lung dysfunction in mice， likely by inhibiting the inflammatory and fibrotic responses mediated through the IL-17/NF-κB/MMP9 signaling pathway.

Objective To explore the necessity of routine chest X-ray (CXR) examination after lung surgery based on patient symptom burden. Methods A retrospective study was conducted on the patients who underwent thoracoscopic lung resection at the Department of Thoracic Surgery of Guangdong Provincial People's Hospital from March 2020 to April 2023. Routine CXR findings obtained within 24 h post-operation, after chest tube removal, and at 1-month post-discharge, as well as subsequent clinical interventions triggered by these examinations, were collected and analyzed. The Perioperative Symptom Assessment Lung (PSA-Lung) inventory was used to quantify symptom burden including pain, dyspnea, and sleep disturbance. Results A total of 2 101 patients were collected, including 986 males and 1 115 females, with a median age of 56 years. The rate of clinical interventions triggered by routine CXR examinations was very low, being 1.0%, 0.5%, and 1.3% within 24 h post-operation, within 12 h after extubation, and at 1-month post-discharge, respectively. One month after discharge, patients in the intervention group exhibited significantly higher scores for dyspnea (3 points vs. 2 points, P=0.015), pain (2 points vs. 1 point, P=0.039), and sleep disturbance (3 points vs. 2 points, P=0.036) compared with the non-intervention group. Conclusion Very few routine postoperative CXR examinations change patients’ management, and patients who need extra-intervention tended to have more severe symptom burden after surgery.

Objective: To investigate the epidemiological characteristics and influencing factors for hand, foot, and mouth disease (HFMD) incidence in Binzhou City, Shandong Province, so as to provide the evidence for developing HFMD prevention and control strategies. Methods: Data on HFMD cases in Binzhou City from 2017 to 2023 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Meteorological data during the same period were collected from the fifth-generation European Centre for Medium-Range Weather Forecasts. The incidence of HFMD was calculated, and the temporal, population, and regional distribution characteristics of HFMD were analyzed descriptively. Bayesian spatiotemporal model was used to analyze the influencing factors for HFMD incidence Results: From 2017 to 2023, a total of 17 314 HFMD cases were reported in Binzhou City, with an annual average reported incidence of 62.57/105. The incidence peak was from June to September, and a secondary peak appeared from October to November in some years. The annual average reported incidences were higher in Bincheng District and Yangxin County, which were 107.41/105 and 72.95/105, respectively. There were 10 461 males and 6 853 females, with a male-to-female ratio of 1.53∶1. The age was mainly 1-3 years, with 11 713 cases accounting for 67.65%. Bayesian spatiotemporal model analysis showed that the risk of HFMD incidence had obvious seasonality and regionality. From 2017 to 2019 and in 2021, the peaks occurred in weeks 24-27 and 44-47 each year, with RR values of 1.771-6.747. From 2022 to 2023, it showed a single peak distribution. The RR values were all >1 in Bincheng District, Yangxin County, and Huimin County. Average temperature (RR=1.092, 95%CI: 1.080-1.105) and average relative humidity (RR=1.015, 95%CI: 1.008-1.022) were positively correlated with the risk of HFMD incidence, while average wind speed (RR=0.749, 95%CI: 0.655-0.856) was negatively correlated with the risk of HFMD incidence. Conclusions HFMD in Binzhou City mainly occurs in summer and in central areas. Males and children aged 1-3 years are high-risk populations. The risk of HFMD incidence increases with the increase of average temperature and average relative humidity, and decreases with the increase of average wind speed.
