ObjectiveTo evaluate the clinical efficacy and economic value of the Jiangsu Traditional Chinese Medicine (TCM) Diagnosis and Treatment Protocol for Dominant Diseases (abbreviated as the Diagnosis and Treatment Protocol) in adult patients with non-severe community-acquired pneumonia (CAP) based on real-world clinical data. MethodsA retrospective real-world cohort study was conducted using electronic medical records of adult patients hospitalized for non-severe CAP from September 1st, 2023 to December 31st, 2024 across 10 TCM hospitals in Jiangsu province. Patients were classified into an exposure group and a non-exposure group based on whether they received Chinese herbal medicine (CHM) according to the Diagnosis and Treatment Protocol. The non-exposure group received only conventional western medicine, while the exposure group additionally received differentiated CHM for at least five consecutive days. Outcomes were compared between two patient groups, including cough resolution rate, sputum resolution rate (assessed by volume, color, and consistency), incidence of abnormal C-reactive protein (CRP), incidence of abnormal white blood cell (WBC) count, and radiographic resolution rate of pulmonary infiltrates on chest imaging. Multivariable logistic regression was performed to identify factors influencing clinical efficacy. Subgroup analyses were conducted according to age, gender, smoking status, history of hypertension, and pneumonia severity score (CURB-65), and the efficacy of treatment for cough and sputum was analyzed within each subgroup. Cost-effectiveness analysis was conducted using cough resolution rate as the outcome measure, evaluating the pharmacoeconomics of the two groups. ResultsA total of 1688 patients were included with 1293 in the exposure group and 395 in the non-exposure group. Compared to the non-exposure group, the exposure group demonstrated significantly higher resolution rates of cough, sputum volume, color, and consistency, as well as a significantly lower incidence of abnormal CRP (P<0.05). No statistically significant difference was observed between the groups in terms of abnormal WBC count and radiographic resolution rate of pulmonary infiltrates (P>0.05). Logistic regression analysis showed that the cough resolution rate in the exposure group was 1.83 times that of the non-exposure group, while the probabilities of resolution in sputum volume, color, and consistency were 1.37, 2.09, and 1.56 times those of the non-exposure group, respectively (P<0.05). Subgroup analyses showed that the exposure group achieved significantly higher cough resolution rates across most subgroups except for populations with a CURB-65 score ≥2 or those with a history of hypertension (P<0.05). Specifically, among females, patients aged ≥18 and <65 years, non-smokers, those without hypertension, and those with a CURB-65 score of 0, the exposure group showed a higher cough resolution rate than the non-exposure group (P<0.05). From an economic perspective, total hospitalization cost, length of stay, antibiotic cost, and CHM cost all differed significantly between groups (P<0.05). The cost-effectiveness ratio (CER) was 10,788.80 CNY/case in the exposure group, while 22,513.80 CNY/case in the non-exposure group. This implies that, compared with the exposure group, the non-exposure group incurred an additional 17,302.27 CNY to achieve one case of cough resolution. When the willingness-to-pay threshold ranged from 0 to 50,000 CNY, the probability of economic advantage was consistently higher in the exposure group than in the non-exposure group. ConclusionOn the basis of conventional western medicine, the addition of CHM in accordance with the Diagnosis and Treatment Protocol can effectively improve clinical symptoms, reduce inflammatory markers, promote clinical recovery, and is more cost-effective in treating adults with non-severe CAP.

ObjectiveTo observe the real‑world effectiveness and economic outcomes of Weishi Qingjin Formula (苇石清金方, WQF) in the treatment of adult community‑acquired pneumonia (CAP) with phlegm‑heat obstructing the lung syndrome. MethodsBased on a multicenter, real-world retrospective cohort study, clinical data were collected from hospitalized adult patients diagnosed with non‑severe CAP and phlegm‑heat obstructing the lung syndrome in 10 traditional Chinese medicine (TCM) hospitals in Jiangsu province. Patients were divided into an exposure group (those who received oral WQF) and a non‑exposure group (those who did not). The following outcomes were compared between the two groups before and after treatment, which were remission rates of clinical symptoms including cough, expectoration (sputum volume, color, consistency), and chest pain, levels of inflammatory markers including C‑reactive protein (CRP) and white blood cell count (WBC), and the rate of pulmonary inflammatory absorption on chest CT. Subgroup analyses were performed based on age, gender, smoking status, presence of hypertension, and the severity of community-acquired pneumonia (CURB‑65) score, comparing the two groups in terms of cough remission rate, chest pain remission rate, and chest CT absorption rate. For health economic evaluation, cost‑effectiveness analysis was used to calculate the cost‑effectiveness ratio (CER) and incremental cost‑effectiveness ratio (ICER). Univariate sensitivity analysis and probabilistic sensitivity analysis were performed to test the robustness of the results. ResultsA total of 647 patients in the exposure group and 1491 patients in the non-exposure group were included in the final statistical analysis. There was no statistically significant difference in length of hospital stay, gender, marital status, smoking history, bronchoscopy history, and comorbidities between the groups (P>0.05), but age, CURB-65 score, and antibiotic use. The exposure group had significantly higher remission rates of cough and sputum consistency than the non-exposure group (P<0.05). After adjusting for confounders using propensity score matching and logistic regression, the cough remission rate in the exposure group was 1.49 times that of the non-exposure group (P<0.01). No significant difference was observed between groups in the reduction rates of CRP and WBC, and in the rate of pulmonary inflammatory absorption on chest CT (P>0.05). Subgroup analyses revealed that the cough remission rate in the exposure group was significantly better than that in the non-exposure group except for patients aged ≥65 years, smokers, hypertensive patients, those using other type antibiotics or not using antibiotics, and those with a CURB-65 score ≥1 (P<0.05). Among smokers, the chest pain remission rate in the exposure group was 4.38 times that of the non-exposure group (P<0.01). No significant difference in chest CT absorption rate was found between groups across subgroups of gender, age, hypertension status, or antibiotic type (P>0.05). In terms of economic evaluation, CER was 10,877.60 CNY/case in the exposure group and 16,773.10 CNY/case in the non-exposure group. Compared to the exposure group, the non-exposure group incurred an additional 15,034.26 CNY to achieve one case of cough resolution, indicating a more favorable cost-effectiveness profile. Probabilistic sensitivity analysis yielded results consistent with the cost-effectiveness analysis, confirming the robustness of the findings. ConclusionWQF demonstrates significant efficacy in improving cough symptoms in the treatment of adult CAP with phlegm-heat obstructing the lung syndrome, and also exhibits favorable economic benefits.

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.

ObjectiveTo analyze the potential risk of infection sources during the consolidation phase of schistosomiasis elimination in Lushan County (a mountainous region) of Sichuan Province, and to provide prevention and control strategies for the consolidation of schistosomiasis elimination achievements in mountainous areas. MethodsIn 2024, one to two villages with historically severe epidemics were selected in the heavily endemic townships of Lushan County as monitoring sites to carry out monitoring for wild animal feces, domestic animals, wild rats, free-roaming dogs, local residents, and mobile populations. Follow-up monitoring for previously infected individuals was carried out in Caoping Village of Siyan Town. Statistical analyses were performed to assess the risks associated with infection sources. ResultsA total of 115 fecal samples from 13 species of wildlife were incubated, with all negative. Blood tests were conducted on 492 cattle, 34 sheep, and 261 dogs, with all negative. A total of 2 520 rodent traps were set, capturing 67 wild rats with a capture rate of 2.66%, and no positive wild rats were found upon dissection. The activity track of 25 loose dogs was 2 212 meters at the farthest, 236 meters at the nearest, and 744 meters on average. a total of 68 wild droppings (all dog feces) were picked up along the way, with all negative. Blood tests were performed on 3 540 local population, yielding 39 blood-positive cases with a blood positive rate of 1.1%. Fecal examinations were conducted on 193 individuals, with all negative. A total of 315 blood tests were performed on the mobile population, identifying 1 positive case with a blood-positive rate of 0.32%. One person received a fecal examination, with zero positive. A follow-up survey of 505 previously infected individuals revealed 5 blood-positive cases, with a positive rate of 0.99%. Fecal examinations were conducted on 15 individuals, with all negative. ConclusionIn this investigation, no local or imported sources of schistosomiasis transmission were found. However, there was a wide variety and a large number of potential sources of infection in the local area. It is necessary to actively explore regional monitoring models for schistosomiasis elimination flexibly adjust prevention and control strategies according to local conditions, achieve precise prevention and control, and consolidate the achievements of elimination.

Objective To address the need for rapid review of automated organ-at-risk (OAR) contouring for head-and-neck cancer in online adaptive radiotherapy, this study used dosimetric indices as the reference standard to evaluate the suitability of geometric similarity metrics and to develop a rapid screening model that balances the risk of missed errors with review efficiency. Methods This retrospective study included 29 patients with head-and-neck radiotherapy, yielding 243 pairs of OAR contours (auto-generated vs. manual). Geometric similarity metrics, including the Dice similarity coefficient (Dice), the 95th percentile Hausdorff distance (HD95), and the maximum Hausdorff distance (HD100), were computed between the two contour sets. Using the dose distributions from clinical treatment plans, dosimetric differences between the two contour sets were calculated for key indices, including mean dose (Dmean) and maximum dose (Dmax). Correlations between geometric metrics and dosimetric differences were analyzed. Dosimetric discrepancy events were defined as Y3Gy using a threshold of 3 Gy. Within a univariable logistic regression triage framework, each geometric metric was used as an independent variable to estimate the probability of Y3Gy. Discriminative performance was assessed using receiver operating characteristic (ROC) curves and precision-recall (PR) curves, with the area under the curve (AUC) including ROC-AUC and PR-AUC. Practical operating thresholds were determined via threshold sweeping. Results Geometric similarity metrics showed weak-to-moderate correlations with dosimetric differences; compared with maximum dose, correlations with mean dose differences were more consistent. Among the evaluated metrics, HD95 achieved the best classification performance for Y3Gy. Threshold sweeping suggested that an HD95 threshold in the range of 4-9 mm can balance the risk of missed discrepancies with the efficiency of automated contour quality assurance (QA). Conclusion Several geometric similarity metrics demonstrated only weak-to-moderate associations with dosimetric differences. For head-and-neck OAR contour QA in this study, HD95 provided the best discriminative performance and can support rapid triage of automated contours, with a practical operating threshold range of 4-9 mm, potentially improving the efficiency of adaptive radiotherapy workflows.

Objective To analyze the relationship between cognitive function, motor ability and the risk of falls in patients during the rehabilitation period after stroke. Methods A total of 330 patients with stroke who received rehabilitation treatment in the hospital from February 2022 to February 2025 were classified into fall group (n=105) and non-fall group (n=225) based on the occurrence of falls during rehabilitation period. The clinical data of patients were collected, and the motor function of patients was evaluated by Fugl-Meyer scale, and the cognitive function of patients was assessed by mini-mental state examination (MMSE). Univariate and logistic multivariate regression analyses were applied to analyze the factors affecting the occurrence of falls. Spearman correlation analysis was performed to analyze the relationship between motor ability, cognitive function and risk of falls. Results The proportions of osteoporosis, malnutrition, sleep disorder and history of falls in the fall group were higher while the education level, Fugl-Meyer score and MMSE score were lower compared to the non-fall group (P<0.05). After logistic multivariate analysis, it was found that osteoporosis, malnutrition, sleep disorder, history of falls, low education level, low Fugl-Meyer score and low MMSE score were risk factors for falls in patients during post-stroke rehabilitation period (P<0.05). Correlation analysis indicated that the motor ability and cognitive function in patients during post-stroke rehabilitation period were negatively associated with the occurrence of falls (r=-0.579, -0.438, P<0.001). Conclusion The cognitive function, motor ability of patients in the post-stroke rehabilitation period are closely related to the risk of falls. Clinically, the risk of falls in patients during post-stroke rehabilitation period can be reduced by improving the motor ability and cognitive function.
