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.

ObjectiveTo elucidate the effects of autonomic neuromodulators [calcium chloride (CaCl₂)-acetylcholine (ACh)] on atrial electrical remodeling and histopathological changes in rats, thereby providing evidence for further investigation into the pathological mechanisms by which autonomic imbalance induces atrial fibrillation (AF). MethodsTen 8-week-old male Sprague-Dawley (SD) rats were randomly divided into experimental and control groups, with 5 rats in each group. The experimental group received daily tail vein injections of a CaCl₂-ACh mixed solution for 28 days, while the control group received an equal volume of saline. Surface electrocardiograms were recorded before and after daily administration. On day 28 of administration, under isoflurane inhalation anesthesia, echocardiography was performed, and then the rats were euthanized by exsanguination under isoflurane anesthesia for tissue collection. Body weight and heart weight of rats were measured, and electrophysiological parameters including AF inducibility, conduction velocity, and conduction dispersion in isolated rat hearts were monitored using the MappingLab multichannel electrophysiological mapping system. HE staining was performed to evaluate atrial tissue architecture and inflammatory cell infiltration. The expression levels of matrix metalloproteinase 9 (MMP-9) and interleukin-1 beta (IL-1β) were analyzed by Western blotting. Masson staining was used to quantitatively analyze the proportional distribution of collagen fibers and myocardial fibers, and to calculate the area of collagen deposition, thereby evaluating the degree of myocardial fibrosis. Wheat germ agglutinin (WGA) staining was used to evaluate morphological changes of cardiomyocytes. Dihydroethidium (DHE) staining was used to detect the level of oxidative stress in atrial myocytes. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining was used to detect atrial cell apoptosis. ResultsCompared with the control group, the experimental group showed obvious arrhythmias on electrocardiograms. Echocardiography after 28 days of administration revealed significant structural remodeling in the experimental group, with a marked increase in left atrial anteroposterior diameter (P < 0.05), and also showed cardiac dysfunction, with significant decreases in left ventricular ejection fraction and left ventricular fractional shortening (P < 0.01). Compared with the control group, the experimental group showed a significantly increased heart weight-to-body weight ratio (P < 0.05), a markedly higher AF inducibility (P < 0.001), a significantly slowed atrial conduction velocity (P < 0.05), an uneven isochronal map with irregular directions, and a significantly increased conduction dispersion (P < 0.01). HE staining showed that atrial myocytes in the experimental group were disorganized, with slight inflammatory cell infiltration. Western blotting showed that the expression levels of MMP-9 and IL-1β in the atrial tissue of the experimental group were significantly upregulated (P < 0.05). Masson staining showed a significant increase in collagen deposition and a significant increase in fibrosis area in the atrial tissue of the experimental group (P < 0.001). WGA staining showed that cardiomyocytes in the experimental group were significantly hypertrophied compared with the control group (P < 0.05). DHE staining and TUNEL staining revealed that the level of oxidative stress in atrial myocytes (P < 0.001) and the apoptotic rate (P < 0.01) were both significantly increased. Conclusion Daily tail vein injections of the autonomic neuromodulator CaCl₂-ACh mixed solution for 28 days can successfully induce AF in rats, accompanied by significant atrial structural remodeling, electrical remodeling, and oxidative stress.

Objective:To develop and validate a combined model integrating radiomics, dosiomics, and clinical parameters based on CT simulation and dosimetric images in order to predict the occurrence of radiation pneumonitis (RP) in patients with non-small cell lung cancer (NSCLC).Methods:A retrospective study was conducted on the clinic data of 143 NSCLC patients who received radiotherapy at the Affiliated Hospital of Jining Medical University from January 2016 to December 2022. Patients were randomly stratified into a training group ( n = 100) and an internal validation group ( n = 43) at a 7∶3 ratio. Moreover, clinic data were collected from 34 NSCLC patients who received radiotherapy at the Jining Cancer Hospital between January 2019 and December 2022 as an external validation group. All three groups (the training group, internal validation, and external validation groups) were further categorized into two groups based on the RP severity (i.e., RP ≥ grade 2 and RP < grade 2). Their radiotherapy dose, CT simulation, and 3D dose distribution images were collected. Then, the total lung minus planning target volume (TL-PTV) was defined as the region of interest (ROI) for radiomics and dosiomic feature extraction, followed by feature dimensionality reduction. Consequently, key features associated with RP were determined. Four predictive models were developed using machine learning approaches (especially multilayer perceptron, MLP): a clinical model (CM), a radiomics model (RM), a dosiomics model (DM), and a radiomics and dosiomics nomogram (RDN), with a nomogram subsequently constructed. Ultimately, the performance and clinical feasibility of these models were assessed using receiver operating characteristic (ROC), area under the curve (AUC), and decision curve analysis (DCA). Results:A total of 1 834 radiomic features and 1 834 dosiomic features were extracted. Using the occurrence of RP ≥ grade 2 as the marker variable, 14 radiomic features, 15 dosiomic features, and three clinical features were selected from the training group to construct the prediction models (CM, RM, DM, and RDN). The performance and generalizability of these models were subsequently validated in both the internal validation and external validation groups. Specifically, the RDN exhibited AUCs of 0.915 (95% CI: 0.852-0.978), 0.879 (95% CI: 0.777-0.982), and 0.838 (95% CI: 0.701-0.975) in the three groups, respectively. A nomogram was established for RDN by integrating the radiomics score (R-score), dosiomics score (D-score), mean lung dose (MLD), V20, and V30. This nomogram allowed for individualized risk estimation of RP and facilitated personalized radiotherapy planning. Conclusions:The RDN model that is developed based on CT simulation and 3D dose distribution images and integrates radiomics, dosiomics, and clinical features can effectively predict the RP risk of NSCLC patients. The integration of multidimensional data contributes to the formation of the optimal predictive model, offering guidance for clinicians.
