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.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective To investigate the neuroprotective effect of ligustilide(LIG)-mediated phosphatase and tensin homolog(PTEN)-induced putative kinase 1(PINK1)/Parkin pathway on mitophagy in rats with cerebral ischemia-reperfusion injury.Methods 161 male Sprague Dawley(SD)rats were randomly divided into sham operation(Sham)group,model group,LIG low-dose group,LIG high-dose group,mitophagy inhibitor(Mdivi-1)group,LIG high-dose+Mdivi-1 group,and the positive drug Nimodipine(NMDP)group,each with 23 rats.A modified middle cerebral artery wire thrombus method was used to construct a cerebral ischemia/reperfusion model in rats,and the neurobehavioral scores of rats in each group were compared by Longa's five-point scale;the volume of cerebral infarction was detected by 2,3,5-triphenyltetrazolium chloride(TCC)staining,the histopathology and ultrastructure of the hippocampus were examined by hematoxylin-eosin(HE)staining and transmission electron microscope(TEM).And the Na+-K+-Adenosine Triphosphate was measured by enzyme-linked immunosorbent assay(ELISA);double immunofluorescence staining for translocase of the outer membrane of mitochondrion 20(TOMM20)and Microtubule-associated protein 1 light chain 3(LC3)co-localized area percentage.Flow cytometry assay(FCM)to test the level of reactive oxygen(ROS);real-time fluorescence quantitative PCR(qRT-PCR)was used to measure the relative content of mitochondria in hippocampal neurons;and Western blot was performed to test the level of autophagy and the PINK1/Parkin pathway related protein expression.Results Compared with the Sham group,the neurological function score and cerebral infarction volume of the model group were increased,the hippocampal neurons showed pathological damage such as disordered arrangement,nucleolus disappearance and partial shrinkage of the nucleus and plasma,nuclear membrane rupture,swelling,membrane rupture and crista reduction of some mitochondria,a large number of autophagosomes were observed,and the colocalization area percentage of TOMM20 and LC3 was increased.TOMM20 and cytochrome C oxidase subunit IV isoform 1(COX4I1)in hippocampus and selective autophagy adaptor protein 62(p62)protein expression,mitochondrial encoded ATP synthase 6(mt-ATP6)/Ribosomal protein L13(Rpl13)ratio and Na+-K+-ATPase content decreased,while PINK1 and Parkin protein expression,LC3-II/I ratio and ROS relative content increased,and the differences were statistically significant(t=4.602～52.012,all P<0.01).Compared with the model group,the neurological function score,cerebral infarction volume,pathological and ultrastructural damage of hippocampal neurons were significantly improved in the LIG low,high dose and NMDP groups,and the differences were statistically significant(t=4.851～12.525,all P<0.01).The colocalization of TOMM20 and LC3 and the content of Na+-K+-ATPase were increased,while the expression of TOMM20,COX4I1 and p62 proteins and the mt-ATP6/Rpl13 ratio were decreased in the high-dose LIG group.The protein expression of PINK1 and Parkin,LC3-II/I ratio and ROS relative content were increased,and the differences were statistically significant(t=4.087～33.211,all P<0.01).Compared with the LIG high-dose group,the Mdivi-1 and LIG+Mdivi-1 groups had significantly decreased colocalization of TOMM20 and LC3 and Na+-K+-ATPase content,and significantly increased expression of TOMM20,COX4I1 and p62 proteins and mt-ATP6/Rpl13 ratio.The protein expression of PINK1 and Parkin,LC3-II/I ratio and ROS relative content were decreased,and the differences were statistically significant(t=4.008～43.415,all P<0.01).However,the percentage of TOMM20 and LC3 co-localization area,PINK1 and Parkin protein expression,LC3-II/I ratio and Na+-K+-ATPase content in the hippocampus of the LIG+Mdivi-1 group were higher than those of the Mdivi-1 group.The protein expression of COX4I1 and p62,mt-ATP6/Rpl13 ratio and ROS level were lower than those in MDIV-1 group,and the differences were statistically significant(t=3.721～21.513,all P<0.01).Conclusion LIG may activate mitophagy by regulating PINK1/Parkin signaling pathway to protect neurons from cerebral ischemia-reperfusion injury in rats.

Objective:To observe effectiveness of combining diffusion tensor imaging (DTI) with motor evoked potentials (MEPs) in evaluating the upper limb motor functioning of stroke survivors.Methods:Thirty-seven stroke survivors with upper limb motor dysfunction were selected. At the 4th, 12th and 24th week after their onset, each was were assessed using Fugl-Meyer Upper Limb (FMA-UE) scoring, the National Institutes of Health stroke scale (NIHSS), the modified Rankin Scale (mRS), the Barthel Index (BI) and hemiplegic hand function classification. DTI was also applied and MEPs were measured. The patients were divided into an MEP positive group and an MEP negative group according to the existence of the MEP waveform. The DTI and MEP parameters were correlated with the FMA-UE scores, linear regressions were evaluated and a receiver operating characteristics curve was prepared to estimate the utility of DTI in predicting hand function. The sensitivity and specificity of MEPs in predicting hand function recovery were evaluated.Results:The asymmetry index (FAa) of the average anisotropy score of the posterior limb of the internal capsule and the FAa of the cerebral peduncle were both significantly correlated with the FMA-UE scores at the 12th and 24th weeks. The best cut-off points for predicting functional recovery of a patient′s hand were 0.155 for the FAa of the posterior limb of the internal capsule and 0.145 for the cerebral peduncle. Among the 37 patients, the MEPs of 8 (the MEP positive group) could be extracted, and their hand functions recovered completely. The sensitivity of the MEPs in predicting the complete recovery of hand function was 80% with 100% specificity. The linear regression analysis showed 77% prediction accuracy for the FAa and MEPs of the cerebral peduncle for upper limb motor function at the 24th week after onset. In the MEP negative group, two patients completely recovered their hand function, with one′s FAa less than 0.145, and the other′s more than 0.145. When the MEP was negative, the sensitivity of DTI in predicting the recovery of hand function was 50% with 81.5% specificity.Conclusions:DTI combined with MEPs can be used as an index to evaluate the prognosis of upper limb motor function in stroke patients.

Objective:To investigate the correlation and influencing factors between sarcopenia and cardiac structure and function in elderly inpatients.Methods:A total of 945 elderly patients, aged 60 years and older, were recruited from the Geriatrics Department at Xuanwu Hospital.Sarcopenia was assessed, while cardiac structure and function were evaluated through echocardiography and NT-proBNP measurements.Results:Patients were classified into two groups: a sarcopenia group(n=185, 19.6%)and a non-sarcopenia group(n=760, 80.4%).Compared to the non-sarcopenia group, the sarcopenia group exhibited a reduction in left atrial diameter(LAD), left ventricular end-diastolic diameter(LVEDD), left ventricular mass(LVM), stroke volume(SV), and cardiac output(CO)(all P<0.05).In contrast, NT-proBNP levels were significantly elevated in the sarcopenia group( P<0.001).Multivariate logistic regression analysis identified older age( OR=1.080, P<0.001)and elevated NT-proBNP( OR=1.001, P<0.001)as independent risk factors for sarcopenia.Conversely, higher LAD( OR=0.858, P<0.001)and LVM( OR=0.988, P=0.002)were recognized as independent protective factors.Additionally, NT-proBNP demonstrated a negative correlation with handgrip strength( r=-0.241, P<0.001), gait speed( r=-0.215, P<0.001), SPPB score( r=-0.270, P<0.001), and appendicular skeletal muscle mass(ASM)( r=-0.208, P<0.001), while exhibiting a positive correlation with the 5-time chair stand test( r=0.169, P<0.001).LVM was positively correlated with handgrip strength( r=0.213, P<0.001)and ASM( r=0.456, P<0.001).Furthermore, LAD was positively correlated with handgrip strength( r=0.071, P=0.029)and ASM( r=0.305, P<0.001). Conclusions:Notably, significant differences exist in cardiac structure and function between elderly patients with sarcopenia and those without.Furthermore, indicators related to sarcopenia are correlated with alterations in cardiac structure and function.

Objective:To explore whether cytoplasmic linker protein 170(CLIP170)affects papillary thyroid cancer(PTC)cell metastasis and invasion and clarify the underlying mechanisms.Methods:We analyzed CLIP170 expression levels in PTC using GEO and TCGA data and con-structed CLIP170 knockdown(CLIP170KD)cells using lentiviral transfection.Then,we evaluated their functions through Transwell transfer and invasion assays.We assessed how CLIP170 affected the cellular actin structure via immunofluorescence analysis.We detected transforming growth factor-β 1(TGF-β1)release in the cell culture medium using enzyme-linked immunosorbent assay(ELISA).We also assessed epithelial-mesenchymal transition(EMT)and TGF-β signaling pathway molecule expression using immunoblotting and reverse-transcription quantitat-ive fluorescence PCR and validated the results in a nude mouse lung metastasis model.Results:CLIP170 expression level in PTC was lower than that in normal thyroid tissue.Regarding the function,CLIP170KD significantly enhanced PTC cell metastasis both in vitro and in vivo.Re-garding the underlying mechanism,CLIP170KD triggered TGF-β pathway activation,subsequently promoted tumor cell migration and invasion.The inhibitor of TGF-β effectively inhibited TGF-β activation,and this inhibition significantly reversed the CLIP170KD-induced tumor metastasis.Conclusions:CLIP170 could be a promising therapeutic target to mitigate metastatic tendencies in PTC.

Purpose/Significance To study the typical characteristics of urban residents when they choose internet medical services,and to establish patient behavior portraits,so as to provide decision-making basis for improving internet medical services.Method/Process Taking patients in Beijing as the research object,patient group portraits are constructed from three dimensions:individual attrib-ute characteristics,online consultation behavior and medical demand preference,and online patient groups are classified by the clustering method.Result/Conclusion Online patients are classified into five distinct groups:value potential,platform loyalty,potential conver-sion,strong demand,and service transfer.Overall,online patients from major cities tend to have lower case severity and lower levels of activity.They typically prefer lower-cost text-based consultations and show a preference for doctors from top-tier hospitals with higher professional titles and superior online service quality.These five different patient groups possess their own typical characteristics,and specific measures need to be taken to meet their personalized medical needs.
