To interpret the evidence-to-decision （EtD） framework and to illustrate its application in traditional Chinese medicine （TCM） guideline development using the example of the Pharmacovigilance Guideline of Chinese Patent Medicine， thereby providing methodological references for TCM guideline standardization. Based on the core three stages of the EtD framework （formulating the question， making an assessment of the evidence， and drawing conclusions）， critical decision points and evaluation evidence within the evidence-translation process were systematically addressed， aligning with the purpose， scope， and key questions of the guideline. Qualitative research methods， such as the nominal group technique， were employed to formulate recommendations. The analysis was conducted based on the EtD framework. During question formulation， the specific characteristics and practical needs of pharmacovigilance for Chinese patent medicines were clarified， focusing on the core objective of safety assurance throughout the product lifecycle. In the evidence assessment， multi-source evidence was integrated， including policy documents， literature research， and expert consensus， completing the evidence evaluation. Finally， in recommendation-forming， dispersed research evidence and expert experience were synthesized into consensus， culminating in the guideline's completion through solicitation of opinions and peer review. The EtD framework provides a structured tool for evidence-to-decision translation in TCM guideline development， effectively enhancing the transparency and scientific rigor of the process. Therefore， it is recommended that TCM guideline development adopt the EtD framework to improve the evidence-to-decision process with TCM characteristics.

To standardize the clinical application of oral Chinese patent medicines （CPMs）， and address the safety issues arising from their dosage form characteristics， irrational clinical use， and the lack of targeted pharmacovigilance systems， the China Association of Chinese Medicine organized the formulation and release of Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines， aiming to inform the safe clinical use of oral CPMs and related pharmacovigilance work. According to the principles of GB/T1.1—2020 and the Drug Administration Law of the People's Republic of China （2019 revision）， the Institute of Basic Research in Clinical Medicine， China Academy of Chinese Medical Sciences， led a drafting group comprising 18 institutions. After multiple rounds of expert interviews， literature retrieval， evidence screening， and extensive solicitation of opinions， the Guidelines were registered internationally. Systematic standardization focused on safety monitoring， risk identification， assessment， control， and other aspects. The Guidelines clarified the characteristics of oral CPMs in terms of safety monitoring， known risks， and potential risks， compared to non-oral CPMs. Then， risk control measures were proposed， including medication in special populations and irrational medication. As a special guideline for pharmacovigilance in the clinical application of oral CPMs， the Guidelines systematically construct a technical system in line with the characteristics of traditional Chinese medicine （TCM）， which is essential for improving the clinical safety management of oral CPMs and provides an important reference for medical institutions， pharmaceutical manufacturers， and regulatory authorities.

In recent years, hybrid brain-computer interfaces (BCIs) have gained significant attention due to their demonstrated advantages in increasing the number of targets and enhancing robustness of the systems. However, Existing studies usually construct BCI systems using intense auditory stimulation and strong central visual stimulation, which lead to poor user experience and indicate a need for improving system comfort. Studies have proved that the use of peripheral visual stimulation and lower intensity of auditory stimulation can effectively boost the user's comfort. Therefore, this study used high-frequency peripheral visual stimulation and 40-dB weak auditory stimulation to elicit steady-state visual evoked potential (SSVEP) and auditory steady-state response (ASSR) signals, building a high-comfort hybrid BCI based on weak audio-visual evoked responses. This system coded 40 targets via 20 high-frequency visual stimulation frequencies and two auditory stimulation frequencies, improving the coding efficiency of BCI systems. Results showed that the hybrid system's averaged classification accuracy was (78.00 ± 12.18) %, and the information transfer rate (ITR) could reached 27.47 bits/min. This study offers new ideas for the design of hybrid BCI paradigm based on imperceptible stimulation.

OBJECTIVES: To investigate the effects of quercetin on cuproptosis and L-type calcium currents in the myocardium of diabetic rats. METHODS: Forty SD rats were randomized into control group and diabetic model groups. The rat models of diabetes mellitus (DM) induced by high-fat and high-sugar diet combined with streptozotocin (STZ) injection were further divided into DM model group, quercetin treatment group, and empagliflozin treatment group (n=10). Blood glucose and body weight were measured every other week, and cardiac function of the rats was evaluated using echocardiography. HE staining, Sirius red staining, and wheat germ agglutinin (WGA) analysis were used to observe the changes in myocardial histomorphology, and serum copper levels and myocardial FDX1 expression were detected. In cultured rat cardiomyocyte H9c2 cells with high-glucose exposure, the effects of quercetin and elesclomol, alone or in combination, on intracellular CK-MB and LDH levels and FDX1 expression were assessed, and the changes in L-type calcium currents were analyzed using patch-clamp technique. RESULTS: The diabetic rats exhibited elevated blood glucose, reduced body weight, impaired left ventricular function, increased serum copper levels and myocardial FDX1 expression, decreased L-type calcium currents, and prolonged action potential duration. Quercetin and empagliflozin treatment significantly lowered blood glucose, improved body weight, and restored cardiac function of the diabetic rats, and compared with empagliflozin, quercetin more effectively reduced serum copper levels, downregulated FDX1 expression, and enhanced myocardial L-type calcium currents in diabetic rats. In H9c2 cells, high glucose exposure significantly increased myocardial expressions of FDX1, CK-MB and LDH, which were effectively lowered by quercetin treatment; Elesclomol further elevated FDX1, CK-MB and LDH levels in the exposed cells, and these changes were not significantly affected by the application of quercetin. CONCLUSIONS Quercetin ameliorates myocardial injury in diabetic rats possibly by suppressing myocardial cuproptosis signaling and restoring L-type calcium channel activity.

Objective To explore the application of serum signal transducer and activator of transcription 3(STAT3),histone deacetylase 2(HDAC2),and developmental endothelial locus-1(Del-1)levels in the evaluation of disease severity and prognosis of children with respiratory syncytial virus pneumonia(RSVP).Methods A total of 109 children with RSVP admitted to Jiamusi Central Hospital from November 2023 to March 2025 were enrolled as the RSVP group.Based on disease severity,RSVP patients were categorized into a low-risk group(n=31),a medium-risk group(n=42),and a high-risk group(n=36).According to the prognosis after 7 days of treatment,they were divided into a favorable prognosis group(n=78)and a poor prognosis group(n=31).Additionally,109 healthy children undergoing physical examination at the same hospital during the same period were selected as the normal control group(NC group).ELISA method was used to detect serum levels of STAT3,HDAC2,and Del-1.Pearson correlation analysis was used to explore the correlations between serum STAT3,HDAC2,Del-1 levels and pulmonary function indices.Multivariate logistic regression analysis was used to explore the factors affecting the prognosis of children with RSVP.Moreover,ROC curve was used to explore the predictive value of serum STAT3,HDAC2,and Del-1 levels for the prognosis of children with RSV.Results Compared with the NC group,the RSVP group had higher serum STAT3 and HDAC2 levels,and lower serum Del-1 levels(P<0.05).Serum STAT3 and HDAC2 levels progressively increased from the low-risk group,medium risk group,to high-risk group,while the time to peak ratio(time to peak tidal expiratory flow to total expiratory time ratio,TPTEF/TE),peak volume ratio(volume to peak expiratory flow to total expired volume ratio,VPEF/VE),and serum Del-1 levels progressively decreased(P<0.05).TPTEF/TE and VPEF/VE were prominently negatively correlated with serum STAT3 and HDAC2 levels,and prominently positively correlated with Del-1 levels(P<0.05).Compared with the favorable prognosis group,the poor prognosis group had significantly lower initial blood oxygen saturation,serum Del-1 levels,and significantly higher serum STAT3 and HDAC2 levels(P<0.05).High expression levels of STAT3 and HDAC2 were independent risk factors affecting the prognosis of children with RSVP,while high expression of Del-1 was an independent protective factor(P<0.05).The AUC values of serum STAT3,HDAC2,and Del-1 levels alone in predicting the prognosis of children with RSV were 0.824,0.818,and 0.842,respectively.The combined prediction AUC was 0.947,which was superior to individual predictions(ZSTAT3-joint=2.436,ZHDAC2-joint=2.570,ZDel-1-joint=2.611,all P<0.05).Conclusion Serum expression of STAT3 and HDAC2 is upregulated,while the expression of Del-1 is down-regulated in children with RSVP.The three markers are closely related to the disease severity and pulmonary function indices,and are important factors affecting the prognosis of children with RSVP.Combined detection of these markers demonstrates high efficacy for prognosis evaluation.

The amount of data generated by the human experience in medical cases of classic formulas is large and the research value is high， but how to extract valuable information from these massive data is an important problem of researches on classical formulas. It is concluded that there are many problems in the current study of human experience in classical formulas， such as large amount of data， uneven quality， weak extrapolation and clinical application， which seriously affected the evidence strength of human experience in classical formulas and the contribution to experience accumulation and theoretical support. Therefore， from the structural perspective of the research questions， this paper proposed the research ideas of human experience in medical cases of classic formulas： firstly， according to the characteristics of traditional Chinese medicine （TCM） cases， based on the PICO model， which refers parti-cipants （P）， intervention （I）， comparisons （C）， and outcomes （O）， a TCM medical record evaluation tool in line with the evidence-based concept was constructed to evaluate the quality of medical cases； secondly， constructing a standardized database of human experience in classical formulas and using data mining algorithms to explore the deep relationship hidden in human experience； finally， the clinical value evaluation is carried out to verify the effectiveness of the diagnosis and treatment rules of classical formulas to achieve clinical transformation.

Objective To establish a simultaneous detection approach for 34 emerging contaminants(ECs)in tap water by liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).Human health risk assessment was performed according to the detection results from 43 tap water samples.Methods Tap water samples were concentrated and extracted by solid phase extraction,and then blown to near dry by nitrogen at 40℃.The sample extracts were dissolved in methanol-water solution(95:5,VN)to 0.5 mL for analyzing.Agilent Jet Stream Electrospray Ionization(AJS ESI)and the multiple reaction monitoring(MRM)mode were performed for MS to acquire the data of 34 ECs.A database including precursor ion,product ion and retention times was established accordingly.Results The average linear correlation coefficients(r)of 34 kinds of ECs was 0.995 9.The limits of detection were 0.01～0.60 ng/L and the recoveries were between 60.7％and 119.8％.The intra-group precisions were between 0.05％～9.89％and the intra-day precisions were between 0.20％～14.40％for the spiked samples.The method was applied to analyze 43 tap water samples and a total of 15 ECs were detected.According to the results,the detection rate of caffeine was the highest(84％),and the concentration range was ND～74.42 ng/L.Among all the ECs detected,1,2,3-benzotriazole had the highest concentration(ND～361.15 ng/L),where detection rate was 44％.Humans may be exposed to these ECs by drinking the tap water.The human health risk assessments of 12 kinds of ECs were carried out,however,the estimated risk was negligible(risk quotient＜0.01).Conclusion The method is simple,highly sensitive and selective,and could meet the detection needs of ECs at trace level in tap water.There was no human health risk posed for ECs identified in 43 tap water samples analyzed by this method.

Objective:To construct a nomogram model for predicting frailty in elderly hypertensive patients, and to evaluate the discrimination and consistency of the model.Methods:A total of 317 patients with essential hypertension who were admitted to Hebei Eighth People′s Hospital from February 2021 to June 2022 were taken, they were divided into modeling group (190 cases) and verification group (127 cases) according to the proportion of 6∶4, the patients in the modeling group were divided into the asthenic group (45 cases) and the non asthenic group (145 cases) according to whether the patients in the modeling group had asthenia. The nomograph model was constructed based on the results of Logistic analysis.Results:The age, obesity or overweight ratio, diabetes ratio and systolic blood pressure in the frail group were significantly higher than those in the non-frail group: (76.25 ± 3.64)years vs.(70.44 ± 3.82) years, 51.11%(23/45) vs. 24.83%(36/145), 46.67%(21/45) vs. 17.24%(25/145), (156.46 ± 18.64) mmHg (1 mmHg = 0.133 kPa) vs. (143.25 ± 12.38) mmHg, and the mini-nutrition assessment summary form (MNA-SF) score was significantly lower than that in the non-frail group: (11.45 ± 2.06) scores vs. (13.12 ± 1.22) scores, there were statistical differences ( P<0.05). Logistic results showed that age, body mass index, diabetes, and systolic blood pressure were the risk factors for frailty ( P<0.05). The receiver operating characteristic (ROC) curve evaluation showed that the area under the curve (AUC) in the modeling group was 0.998, and AUC in the validation group was 0.954. The Hosmer-Lemeshow goodness of fit test showed: modeling group χ2 = 6.18, P = 0.627; validation group χ2 = 6.58, P = 0.582. Conclusions:The nomogram prediction model of frailty risk in elderly hypertensive patients has good consistency and differentiation
