Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

OBJECTIVE To construct a classification prediction model for vancomycin blood concentration, and to optimize its precision dosing strategies. METHODS Patient records meeting inclusion criteria were extracted from the Medical Information Mart for Intensive Care database. Following data cleaning and preprocessing, a final cohort of 9 902 patient was analyzed. Feature selection was performed through correlation analysis and the Boruta feature selection algorithm. Vancomycin blood concentrations were discretized into three categories based on clinical therapeutic windows: low (<10 μg/mL), intermediate (10-20 μg/mL), and high (≥20 μg/mL). Six machine learning algorithms were employed to construct classification models: tabular prior-data fitted network (TabPFN), logistic regression (LR), random forest (RF), extreme gradient boosting (XGBoost), support vector machine (SVM), K-nearest neighbors (KNN). Model performance was evaluated using 10-fold cross-validation (10-CV), with primary metrics including: accuracy, balanced accuracy, precision macro, recall macro, macro F1, area under the receiver operating characteristic curve (OvR-AUC). Shapley Additive Explanations (SHAP) was adopted to analyze the direction and magnitude of the impact that different features had on the model’s predictive outcomes. RESULTS The results showed that the RF and TabPFN models performed the best (with accuracy of 0.741 4 and 0.737 7, and OvR-AUC of 0.907 0 and 0.895 8, respectively). XGBoost model exhibited moderate performance, while LR, SVM, and KNN models demonstrated relatively poor performance. Confusion matrix heatmap analysis revealed that both RF and TabPFN achieved higher accuracy in predicting high- concentration cases but exhibited slightly lower performance in the low and medium concentration categories. Bootstrap with 10-CV revealed that the RF model demonstrated stable performance across various evaluation metrics (accuracy: 0.741 4; balanced accuracy: 0.740 3; precision macro: 0.732 1; recall macro: 0.736 0; macro F1: 0.736 0; OvR-AUC: 0.907 0), indicating good classification performance and generalization ability. SHAP analysis revealed that creatinine, urea nitrogen, daily cumulative dose and administration frequency of vancomycin, which were key predictors, had a significant impact on the prediction results. CONCLUSIONS RF and TabPFN models demonstrate certain advantages in the classification prediction of vancomycin trough blood concentrations; however, their performance in the low to moderate concentration categories still requires improvement.

【Objective】 To evaluate the efficacy and safety of plasma-derived human coagulation factor Ⅷ (FⅧ) in the treatment of patients with hemophilia A. 【Methods】 A multi-center and open, SAT(single-arm trials) clinical study was conducted. A total of 54 subjects with hemophilia A were enrolled in 5 research centers. FⅧ was injected according to the subjects' weight, severity of disease and other factors, and the transfusion efficiency of FⅧ activity at 10 min after the first infusion of the first bleeding event was taken as the main efficacy indexes. The improvement scores of bleeding symptoms and signs within 24 h after the first infusion of the first bleeding event were the secondary efficacy indexes. The pathogenic microbial indexes and FⅧ inhibitors were detected on 90(th) and 180(th) day after treatment. 【Results】 The transfusion efficiency of FⅧ activity of 54 subjects at 10 min after the first infusion was 171.9% on average, with median of 169.5%, both higher than the target value of 100%. Within 24 h after the first infusion, the improvement of bleeding symptoms and signs of the subjects were scored, among which 19 cases (35.2%) were "obvious", 35 cases (64.8%) were "good", and the total clinical effective rate reached 100%. Five subjects (9.3%) had six drug-related adverse events. On 90(th) and 180(th) day after treatment, hepatitis B surface antigen, hepatitis C antibody, HIV antibody, treponema pallidum antibody and FⅧ inhibitors were detected, and no negative to positive cases were found. 【Conclusion】 After infusion, the FⅧ preparation can significantly improve the FⅧ activity level in hemophilia A patients in a short period of time, which has high infusion efficiency and can achieve better treatment efficacy, and can also effectively control and relieve bleeding symptoms and signs, with good overall safety.

Patients with acute heart failure (AHF) often experience dyspnea, and monitoring and quantifying their breathing patterns can provide reference information for disease and prognosis assessment. In this study, 39 AHF patients and 24 healthy subjects were included. Nighttime chest-abdominal respiratory signals were collected using wearable devices, and the differences in nocturnal breathing patterns between the two groups were quantitatively analyzed. Compared with the healthy group, the AHF group showed a higher mean breathing rate (BR_mean) [(21.03 ± 3.84) beat/min vs. (15.95 ± 3.08) beat/min, P < 0.001], and larger R_RSBI_cv [70.96% (54.34%-104.28)% vs. 58.48% (45.34%-65.95)%, P = 0.005], greater AB_ratio_cv [(22.52 ± 7.14)% vs. (17.10 ± 6.83)%, P = 0.004], and smaller SampEn (0.67 ± 0.37 vs. 1.01 ± 0.29, P < 0.001). Additionally, the mean inspiratory time (TI_mean) and expiration time (TE_mean) were shorter, TI_cv and TE_cv were greater. Furthermore, the LBI_cv was greater, while SD1 and SD2 on the Poincare plot were larger in the AHF group, all of which showed statistically significant differences. Logistic regression calibration revealed that the TI_mean reduction was a risk factor for AHF. The BR_ mean demonstrated the strongest ability to distinguish between the two groups, with an area under the curve (AUC) of 0.846. Parameters such as breathing period, amplitude, coordination, and nonlinear parameters effectively quantify abnormal breathing patterns in AHF patients. Specifically, the reduction in TI_mean serves as a risk factor for AHF, while the BR_mean distinguishes between the two groups. These findings have the potential to provide new information for the assessment of AHF patients.

【Objective】 To explore the recruitment and retention strategy of blood donors by investigating the age composition of blood donors in some areas of China, so as to promote blood donation and enhance clinical blood supply. 【Methods】 Through the working platform of Practice Comparison Working Group of China’s Mainland Blood Collection and Supply Institutions, the average age and age composition of blood donors from 22 blood centers were collected, and statistical analysis was conducted after eliminating invalid data. 【Results】 The median average age of blood donors during the survey year was 30.02.The median age in 2.89% of the blood centers was lower than 25. The average age of different genders was statistically significant only in 2018(P<0.05). Fot first-time blood donors, the median constituent ratio of donors <25 and ≥25 years old was 54.53% and 44.28%, with median retention rate at 10.30% and 9.61%, respectively. The median overall participation rate of blood donors was 2.7%, with median participation rate of blood donors <25 years old at 5.1%. 【Conclusion】 The recruitment and retention of blood donor is crucial to enhance clinical blood supply. Blood donors <25 years old, with a longer period for future donation, should be the main target of blood donation recruitment. Meanwhile, the revision of upper age limit for blood donation is another important initiative to grow the blood donor pool.
