Objective To develop an artificial intelligence (AI)-driven lung cancer database by structuring and standardizing clinical data, enabling advanced data mining for lung cancer research, and providing high-quality data for real-world studies. Methods Building on the extensive clinical data resources of the Department of Thoracic Surgery at Peking Union Medical College Hospital, this study utilized machine learning techniques, particularly natural language processing (NLP), to automatically process unstructured data from electronic medical records, examination reports, and pathology reports, converting them into structured formats. Data governance and automated cleaning methods were employed to ensure data integrity and consistency. Results As of September 2024, the database included comprehensive data from 18 811 patients, encompassing inpatient and outpatient records, examination and pathology reports, physician orders, and follow-up information, creating a well-structured, multi-dimensional dataset with rich variables. The database’s real-time querying and multi-layer filtering functions enabled researchers to efficiently retrieve study data that meet specific criteria, significantly enhancing data processing speed and advancing research progress. In a real-world application exploring the prognosis of non-small cell lung cancer, the database facilitated the rapid analysis of prognostic factors. Research findings indicated that factors such as tumor staging and comorbidities had a significant impact on patient survival rates, further demonstrating the database’s value in clinical big data mining. Conclusion The AI-driven lung cancer database enhances data management and analysis efficiency, providing strong support for large-scale clinical research, retrospective studies, and disease management. With the ongoing integration of large language models and multi-modal data, the database’s precision and analytical capabilities are expected to improve further, providing stronger support for big data mining and real-world research of lung cancer.

Gentianopsis barbata (G. barbata) represents a significant plant species with considerable ornamental and medicinal value in China. This investigation sought to elucidate the primary constituents within the plant and investigate their pharmacological properties. Fifty triterpenoids (1-50), including nine previously undescribed compounds (1, 2, 7, 10, 20, 28, 29, 37, and 41) were isolated and characterized from the whole plants of G. barbata. Notably, compounds 1 and 2 exhibited the novel 3,4;9,10-diseco-24-homo-cycloartane triterpenoid skeleton. The isolated triterpenoids demonstrated substantial anti-inflammatory activity through inhibition of tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) cytokine secretion in LPS-induced RAW264.7 macrophages, and hepatoprotective effects by preventing tert-butyl hydroperoxide (t-BHP)-induced oxidative injury in HepG2 cells. These results demonstrate both the presence of diverse triterpenoids in G. barbata and their therapeutic potential for inflammatory and hepatic conditions, providing scientific evidence supporting the clinical application of this traditional Mongolian medicinal plant.

Background Water serves as an indispensable resource for human survival and constitutes one of the primary means through which humans are exposed to environmental chemicals. Consequently, the safety of drinking water is critical to safeguarding public health. Objective To analyze the levels of the 10 metal/metalloid indicators [Al, Fe, Mn, Cu, Zn, As, Cd, Cr(VI), Pb, and Hg] in drinking water from a region of the Fuchun River Basin, and to evaluate the health risks in drinking water through oral ingestion. Methods In accordance with the national Standard Examination Method for Drinking Water – Part 2: Collection and Preservation of Water Samples (GB/T 5750-2006 and GB/T 5750-2023), a total of 2016 drinking water samples were collected from urban and rural water supply systems in a region of the Fuchun Basin from 2017 to 2024. Two batches of water samples were collected annually during the dry and wet seasons, with each batch comprising 72 samples from the urban water supply system and 54 samples from the rural water supply system. These samples were analyzed according to the Standard Examination Method for Drinking Water – Part 6: Metal and Metalloid Indicators (GB/T 5750-2006 and GB/T 5750-2023) and the results were compared with the limits specified in the Standards for Drinking Water Quality (GB 5749-2022). Health risks were evaluated using the U.S. Environmental Protection Agency (EPA) health risk assessment model. Results All tested metal/metalloid elements in the drinking water samples of the area met the national standards. The results of risk assessment showed that the non-carcinogenic risks associated with oral intake of drinking water, ranked from highest to lowest, were as follows: As>Cr(VI)>Pb>Cd>Hg>Mn>Cu>Zn>Fe>Al, with values of 4.55×10⁻², 2.79×10⁻², 2.06×10⁻², 1.20×10⁻², 4.95×10⁻³, 4.58×10⁻³, 2.85×10⁻³, 1.95×10⁻³, 1.52×10⁻³, and 9.21×10⁻⁴, respectively. The non-carcinogenic risk of each indicator was less than 1, which suggested no potential risk to population health. The carcinogenic risks ranked as Cr(VI)>As>Cd>Pb, with values of 4.18×10⁻⁵, 2.05×10⁻⁵, 3.85×10⁻⁶, and 2.45×10⁻⁷, respectively. The carcinogenic risks of Cr(VI), As, and Cd were between 10⁻⁶ and 10⁻⁴, which suggested an acceptable carcinogenic risk, while the carcinogenic risk of Pb was relatively negligible. Children's total non-carcinogenic/total carcinogenic risks were comparable to those of adult males, both higher than those of adult females. Additionally, rural areas exhibited higher non-carcinogenic/carcinogenic risks for Cr(VI), while those risks for As and Pb were lower than those in urban water samples, and those risks for Cd were comparable between the two. Conclusion The concentrations of the 10 metal/metalloid indicators in drinking water from the studied region in the Fuchun River Basin comply with the national standards from 2017 to 2024. There is a certain carcinogenic risk associated with oral intake of drinking water, but it is still within the acceptable range. In terms of non-carcinogenic risk, no potential threat to population health is anticipated.

This paper summarized the key points and methods in terms of the establishment of the guideline working group and the management of conflict of interests， trying to provide reference for the development of clinical practice guidelines for Chinese patent medicine （CPM）. The establishment of the working group is the first important step for developing CPM guidelines. Considering the characteristics of the clinical practice guidelines for CPM， this study suggests that the three key elements of ‘multidisciplinarity’， ‘clinical relevance’ and ‘geographical representativeness’ should be put focus on when forming the working group. The guideline advisory committee， clinical expert group， evidence systematic evaluation group， secretary group and the external review group should be established. All group members should clarify the conflict of interest， and the process and management method of the conflict of interest should be clearly reported.

Objective:To explore the association of frailty and serum C-terminal agrin fragment(CAF)with the prognosis of elderly patients with acute coronary syndrome(ACS).Methods:In this prospective cohort study, clinical data of 207 older patients with ACS between January 2020 and May 2022 were collected.Serum samples were obtained within 24 hours after enrollment to detect CAF levels.Meanwhile, the thrombolysis in myocardial infarction(TIMI)and frailty screening questionnaire(FSQ)scores were assessed on admission.Patients were followed up for major adverse cardiovascular and cerebrovascular events(MACCE)for 90 days.Multivariate logistic regression was used to analyze the influencing factors of MACCE.The receiver operating characteristic(ROC)curve was performed to evaluate the predictive ability of the FSQ score, serum CAF and their combination for MACCE.According to 90-day mortality, patients were divided into a survival group(n=176)and a death group(n=31). The Cox proportional hazards regression model was used for survival analysis.Results:The FSQ score( Z=4.412, P<0.001)and serum CAF( Z=6.702, P<0.001)in the MACCE group were higher than those in the non-MACCE group.Logistic regression analysis showed that after adjusting for age, sex, TIMI score and complete revascularization, frailty defined by FSQ( OR=1.714; 95% CI: 1.059-2.775; P=0.028)and high serum CAF( OR=1.230; 95% CI: 1.122-1.350; P<0.05)were independent risk factors for MACCE.The area under the ROC curve(AUC)of the FSQ score for predicting MACCE was 0.797(95% CI: 0.735-0.850; P<0.001), the predictive cut-off point was an FSQ score >2, and the Youden index(YI)was 0.419, yielding a sensitivity of 0.708 and a specificity of 0.711.In addition, the AUC of serum CAF for predicting MACCE was 0.766(95% CI: 0.701-0.822; P<0.001), the predictive cut-off point was >6.01 μg/L, and YI was 0.460, yielding a sensitivity of 0.750 and a specificity of 0.710.The predictive ability of FSQ combined with CAF for MACCE was higher than FSQ( Z=2.294, P=0.022)or CAF( Z=2.545, P=0.011)alone.Cox regression analysis showed that frailty defined by FSQ( HR=3.487; 95% CI: 1.329-9.153; P=0.011)was independently associated with all-cause mortality within 90 days after ACS. Conclusions:Frailty assessment and serum CAF detection can improve the risk stratification of elderly patients with ACS.

Objective:To establish a 14-day prognosis model for emergency patients with acute ischemic cerebral stroke and evaluate its predictive efficacy.Methods:A prospective cohort study was conducted. Patients with acute ischemic stroke admitted to the emergency department of Beijing Bo’ai Hospital within 72 hours of onset from October 2018 to December 2020 were enrolled. Univariate and multivariate logistic regression analysis were used to screen the risk factors of poor prognosis. The ROC curve was drawn to determine the cut-off value of continuous variables and discretise data with reference to clinical practice. The corresponding scores were set up according to the β regression coefficient of each variable, and the clinical scale prediction model of short-term prognosis of acute cerebral infarction was established. Patients with ischemic stroke in the hospital from January to December 2021 were selected as the internal validation, to verify the constructed predictive model.Results:A total of 321 patients were included in the study, including 223 in the training set and 98 in the internal validation set. Multivariate logistic regression analysis showed that age, hypersensitive C-reactive protein, prealbumin (PA), infarct volume, Frailty Screening Questionnaire (FSQ) and National Institute of Health Stroke Scale (NIHSS) were independent risk factors for poor short-term prognosis of acute cerebral infarction. The total score of the clinical prediction scoring system for short-term prognosis of acute cerebral infarction in the emergency department was 15 points, including age ≥74 years (1 point), PA ≤373 mg/L (2 points), large artery atherosclerosis (1 point), cardiogenic embolism (2 points), infarct volume ≥ 2.18 cm 3 (2 points), FSQ ≥3 points (1 point), NIHSS ≥4 points (6 points); The area under the ROC curve (AUC) of the scoring system for predicting short-term poor prognosis of acute cerebral infarction was 0.927 (95% CI: 0.894-0.960). The optimal cut-off value was ≥5 points, and the sensitivity and specificity were 0.770 and 0.976, respectively. In the internal validation set, the scoring system had similar predictive value for poor outcomes (AUC=0.892, 95% CI:0.827-0.957). Conclusion:The scoring system for short-term prognosis prediction of acute ischemic cerebral infarction has good diagnostic efficacy, and could guide clinicians to judge the prognosis of emergency patients in the early stage.

Objective:To examine the prevalence of frailty among elderly patients in the emergency department and to investigate the potential relationship between vitamin D nutritional status and frailty.Methods:This study collected clinical data from elderly patients aged over 65 years in the emergency intensive care unit and emergency observation ward of Beijing Bo'Ai Hospital from January to September 2021.The data included blood routine, biochemical indicators, circulating interleukin-6, cortisol, thyrotropin, and 25-hydroxyvitamin D[25(OH)D], which were detected within 24 hours after enrollment.Additionally, the Frailty Screening Questionnaire(FSQ), FRAIL scale, and Clinical Frailty Scale(CFS)were used to score the patients.Based on the scores, the patients were divided into frail or non-frail groups, and the prevalence of frailty was reported accordingly using the criteria of the aforementioned scales.The consistency of the three scales was evaluated using the Spearman rank test and Kappa coefficient.We compared the differences in clinical data and laboratory indicators of patients between the frail and non-frail groups.Additionally, we used a multivariable Logistic regression model to analyze the association between vitamin D nutritional status and frailty.We also analyzed the prevalence of frailty in different vitamin D nutritional statuses and evaluated the predictive ability of serum 25(OH)D for frailty using the receiver operating characteristic(ROC)curve.Results:A total of 317 patients were included in the study.The prevalence of frailty in elderly patients in the emergency department was found to be 47.0%, 55.2%, and 69.4% according to the FSQ, FRAIL, and CFS scales, respectively.The study evaluated the consistency of these three scales, revealing a Spearman rank correlation coefficient of 0.761(95% CI: 0.715-0.806, P<0.001)and a Kappa coefficient of 0.536(95% CI: 0.451-0.621, P<0.001)between FSQ and FRAIL, which were the highest correlations observed.Logistic regression analysis, after adjusting for age, gender, BMI, and other factors, indicated that vitamin D deficiency( OR=5.994, 95% CI: 1.232-29.169, P=0.027)was independently associated with an increased prevalence of frailty as defined by FSQ criteria.The prevalence of frailty increased with the severity of vitamin D malnutrition.In the vitamin D deficiency group, the prevalence was higher compared to the vitamin D insufficiency and sufficiency groups( P<0.05 for all).The area under the ROC curves(AUCs)of serum 25(OH)D levels to predict frailty, as defined by FSQ, FRAIL, and CFS, were 0.806(95% CI: 0.744-0.868), 0.748(95% CI: 0.679-0.817), and 0.768(95% CI: 0.701-0.826)( P<0.001 for all).The optimal cut-off values were 12.0, 9.76, and 11.65 μg/L, respectively, yielding a Youden index of 0.553, 0.419, and 0.462. Conclusions:FSQ, FRAIL, and CFS demonstrated a strong level of consistency in assessing frailty.Additionally, serum 25(OH)D can serve as an independent predictor of frailty, aiding in the identification of frail individuals and enhancing the risk stratification of elderly patients in the emergency department.

Objective:To investigate the association between serum interleukin (IL) -6 and silent information regulator (SIRT) -1 and frailty in elderly patients in the emergency department.Methods:This was a cross-sectional study. Patients aged 60 years and above treated in the emergency department of Beijing Bo'Ai Hospital from January to December 2022 were collected. Blood routine, biochemical indicators, and serum IL-6 were detected within 24 h after enrollment. At the same time, fasting venous blood 2 mL was collected and the serum was stored at minus 80℃ after centrifugation. The level of SIRT-1 was detected by enzyme-linked immunosorbent assay. Nutritional risk screening 2002 was performed within 72 h, Barthel index was used to assess the ability of daily living and grip strength was measured. The patients were divided into frailty and non-frailty groups according to Fried frailty phenotype (FP). The differences of clinical data and laboratory indicators were compared between the two groups. Multivariable logistic regression model was used to analyze the association between serum IL-6, SIRT-1 and frailty. The predictive ability of serum IL-6 and SIRT-1 for frailty was evaluated by the receiver operating characteristic (ROC) curve.Results:A total of 316 elderly patients in the emergency department were included in this study and divided into frailty group ( n=156) and non-frailty group ( n=160) according to Fried FP criteria. Univariate analysis showed that serum IL-6 [33.3 (13.0, 69.2) ng/L vs. 20.0 (9.2, 41.3) ng/L, P=0.001] and SIRT-1 [(9.98±1.23) μg/L vs. (8.98±1.65) μg/L, P<0.001] of patients in the frailty group were higher than those in the non-frailty group. Multivariable logistic regression analysis showed that serum IL-6 ( OR=1.006, 95% CI: 1.001-1.011, P=0.036) and SIRT-1 ( OR=1.838, 95% CI: 1.475-2.290, P<0.001) were independently associated with frailty after adjusting for age, sex, body mass index, Barthel index and grip strength. The area under the curve (AUC) of serum IL-6 for predicting frailty was 0.671 (95% CI: 0.604-0.738, P<0.001), the predictive cut-off point was 33.8 ng/L. The AUC of SIRT-1 for predicting frailty was 0.736 (95% CI: 0.674-0.799, P<0.001), the predictive cut-off point was 9.13 μg/L. The AUC of the model of IL-6 combined with SIRT-1 was 0.765 (95% CI: 0.707-0.823, P<0.001), the sensitivity and specificity were 0.776 and 0.726, respectively, and its predictive efficacy was superior to that of IL-6 alone ( Z=2.119, P=0.034). Conclusion:Serum IL-6 and SIRT-1 are independent predictors of frailty in elderly patients in the emergency department.

Objective: To evaluate the efficacy and safety of Qili Qiangxin Capsule (QLQXC) combined with western medicine in patients with ischemic cardiomyopathy (ICM) comorbid with heart failure (HF) for clinical application. Methods: We searched relevant references in Chinese databases including China National Knowledge Infrastructure (CNKI), China Scientific Journal Database (VIP), Wanfang Database, and China Biology Medicine (CBM), as well as English databases including PubMed and Embase, from the foundation of the database to January 8, 2023, without language restrictions. All statistical analyses, including subgroup and sensitivity analyses, were performed using the Review Manager (version 5.4) and Stata (version 15.0). Results: QLQXC combined with western medicine significantly increased the endpoints of overall response rate (ORR) (P< 0.000 01), left ventricular ejection fraction (LVEF) (P< 0.000 01), the score of Minnesota Living with Heart Failure Questionnaire (MLHFQ) (P = 0.000 2), and 6-minute walking distance (6MWD) (P < 0.000 01), decreased left ventricular end-diastolic diameter (LVEDD) (P < 0.000 01), left ventricular end-systolic diameter (LVESD) (P = 0.03), and pro-brain natriuretic peptide (pro-BNP) (P < 0.000 01), and reduced the incidence of rehospitalization (P = 0.000 3) and adverse events (AEs) (P = 0.000 6) compared with those under the conventional western therapy alone. Nonetheless, no significant difference was observed in reducing the mortality between the QLQXC combined with western medicine group and the western medicine group (P = 0.30). Conclusion The combination therapy of QLQXC with western medicine can potentiate cardiac function and raise the quality of life in patients with ICM comorbid with HF.

ObjectiveTo investigate the association between serum 25-hydroxy vitamin D [25(OH)D] and the occurrence and outcome of stroke-associated pneumonia (SAP) in patients with acute ischemic stroke (AIS) in emergency ward. MethodsThe clinical data of 256 patients with AIS from January, 2019 to December, 2021 were collected in the emergency department of Beijing Bo'ai Hospital. Blood routine, biochemical indicators and serum concentration of 25(OH)D were detected within 24 hours after enrollment; meanwhile, National Institute of Health Stroke Scale (NIHSS) and A2DS2 score were evaluated. The patients were divided into non-SAP group (n = 164) and SAP group (n = 92) according to whether pneumonia occurred during hospitalization. Multivariable logistic regression model was used to analyze the influencing factors of SAP. The predictive ability of serum 25(OH)D and A2DS2 for SAP were evaluated by receiver operating characteristic (ROC) curves. The 28-day survival of patients with SAP was followed up. Multivariable Cox proportional hazard regression model was used to investigate the association between vitamin D nutritional status and 28-day all-cause mortality. ResultsSerum 25(OH)D was significantly lower in the SAP group than that in the non-SAP group (Z = 6.896, P < 0.001). After adjusting age, sex, infarct volume, A2DS2 score and other factors, lower serum 25(OH)D level (OR = 0.934, 95%CI 0.884 to 0.986, P = 0.014) was an independent risk factor for SAP. The areas under curve (95%CI) of serum 25(OH)D, A2DS2 score and their combined model for predicting SAP were 0.774 (0.718 to 0.824), 0.832 (0.781 to 0.876) and 0.851 (0.802 to 0.893) (P < 0.001), respectively; and the optimum cut-off values were 25(OH)D < 10.2 ng/mL, A2DS2 score > 5 points, combined prediction > 0.207, and the Youden index were 0.493, 0.662 and 0.616, respectively. A2DS2 score could improve the prediction efficiency of serum 25(OH)D (Z = 2.106, P = 0.035). After adjusting age, sex, infarct volume and NIHSS score, vitamin D deficiency was an independent risk factor for all-cause mortality after 28 days of SAP (HR = 2.871, 95%CI 1.004 to 8.208, P = 0.049) . ConclusionSerum 25(OH)D is independently associated with the occurrence and outcome of SAP in patients with AIS in emergency ward, which could serve as an independent predictor for SAP.
