Based on the theory of evidence-based medicine （EBM）， this paper systematically constructed a multi-dimensional evaluation framework for traditional Chinese medicine （TCM） appropriate technologies， encompassing three core dimensions including evidence， practitioner， and patient. For the current practical challenges in the promotion of TCM technologies such as lack of high-quality evidence， inconsistent operational standards， and varying patient acceptance， the paper proposed the integration of published literature evidence and real-world research data to construct a scientific and applicable evaluation pathway. Regarding the evidence dimension， it emphasizes syste-matic assessment of effectiveness， safety， and economic efficiency， introducing methods like the target trial emulation framework to enhance evidence quality； for the practitioner dimension， it suggests developing multi-aspects competency evaluation tools based on educational background， training assessment， and clinical outcomes； for the patient dimension， it recommends designing patient acceptance assessment tools by considering factors such as technical characte-ristics， expected efficacy， patient-practitioner interaction， and the availability of alternative treatments. The purpose of the above measures is to provide methodological support for the standardized popularization and precision application of TCM appropriate technologies.

BackgroundNegative symptoms of schizophrenia impose a substantial burden on society， and the current antipsychotic drugs have limited efficacy in treating these symptoms. Intermittent theta burst stimulation （iTBS）， as a novel neuromodulation technique， shows potential therapeutic promise. However， the evidence for its efficacy in treating negative symptoms of schizophrenia and its relationship with associated immuno-inflammatory changes remain to be further elucidated. ObjectiveTo investigate the efficacy of iTBS targeting the left dorsolateral prefrontal cortex （L-DLPFC） on persistent negative symptoms of schizophrenia， and to analyze its relationship with changes in peripheral blood inflammatory markers， so as to provide references for the clinical application of iTBS in treating persistent negative symptoms and to offer clues for further research into its potential biological mechanisms. MethodsA randomized， double-blind， sham-controlled clinical trial was conducted. A total of 60 patients with schizophrenia who were hospitalized at Xuzhou Oriental Peopple's Hospital from February 20， 2024 to May 10， 2025 were consecutively enrolled. All patients met the diagnostic criteria for schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） and fulfilled the criteria for persistent negative symptoms. Participants were randomly assigned into the study group and the control group， with 30 patients in each group. The two groups respectively received 20 sessions of either active iTBS or sham stimulation over a 4-week period. Clinical symptoms were assessed using the Positive and Negative Syndrome Scale （PANSS） at the baseline， the end of treatment， and 3 months after treatment. Peripheral blood inflammatory markers were measured at the baseline and at the end of treatment， including white blood cell count， platelet count， neutrophil count， lymphocyte count， and monocyte count， the neutrophil-to-lymphocyte ratio （NLR）， monocyte-to-lymphocyte ratio （MLR）， and platelet-to-lymphocyte ratio （PLR） were also calculated. A linear mixed model was used to compare PANSS scores between the two groups. Spearman correlation analysis was performed to examine the association between reductions in inflammatory markers at the end of treatment and reductions in PANSS negative symptom subscale scores， with body mass index （BMI） and chlorpromazine-equivalent dose as covariates. Results①The time-group interaction effect for the PANSS negative symptom subscale score was statistically significant （F=5.410， P<0.01）. At the end of treatment and 3 months after treatment， the study group had significantly lower scores on the PANSS negative symptom subscale than the control group （P<0.01）. ② At the end of treatment， group differences in reduction scores for neutrophil count， NLR， and PLR were significant （Z=-2.262， -2.048， -2.070， P<0.05）. However， after FDR correction， the between-group differences in reductions in peripheral blood inflammatory markers were no longer statistically significant （P>0.05）. ③ After adjusting for BMI and chlorpromazine equivalents， the reduction in PANSS negative symptom subscale scores was positively correlated with the reduction in neutrophil count in the study group （r_s=0.382， P=0.045）. ConclusioniTBS targeting the L-DLPFC may be beneficial in improving persistent negative symptoms of schizophrenia， and its clinical efficacy may be associated with changes in neutrophil count. ［Funded by National Natural Science Foundation of China （number， 82371510）； Social Development Project of Jiangsu Province （number， BE2023668）. www.chictr.org.cn number， ChiCTR2500101060］

Objective To observe the repair effect and mechanism of Danhuang Powder-containing serum on high glucose-induced vascular endothelial cell injury.Methods Danhuang Powder-containing serum was prepared.Human umbilical vein endothelial cells(HUVECs)were cultured to be divided into control group,recombinant human epidermal growth factor(called"growth factor"for short)group,Danhuang Powder group,high glucose group,high glucose+growth factor group,and high glucose+Danhuang Powder group.After corresponding intervention in each group for 48 hours,the cell ultrastructure and autophagy were observed under transmission electron microscope,apoptosis was detected by flow cytometry,and the protein expression levels of vascular endothelial growth factor(VEGF),epidermal growth factor(EGF)and basic fibroblast growth factor(bFGF)in the cells were detected by Western Blot.Results(1)The intra-mitochondrial ridges in the control group were clearly visible,autophagosomes and autolysosomes were fewer;mitochondria in the high glucose group were swollen and irregular,and appeared vacuolated;and the more typical autophagy-like structures were seen in the high glucose+Danhuang Powder group.(2)Compared with the high glucose group and high glucose+growth factor group,the apoptosis rate of cells in the high glucose+Danhuang Powder group was significantly decreased(P<0.05).(3)Compared with the high glucose group and the high glucose+growth factor group,the protein expression levels of VEGF,EGF and bFGF in the cells of the high glucose+Danhuang Powder group were significantly increased(P<0.05).Conclusion Danhuang Powder-containing serum can reduce the high glucose-induced damage in HUVEC cells,and its mechanism may be related to the activation of mitochondrial autophagy,and the inhibition of apoptosis,as well as the up-regulation of the expression of VEGF,EGF and bFGF.

Objective To examine the association between sleep and depressive symptoms among community-dwelling older adults and whether loneliness mediates this association.Methods Using a multistage sampling approach,we enrolled participants aged 60 years or older from two communities in Chengdu,China.A questionnaire was used to collect basic information,including age,sex,etc.,from the participants.In addition,loneliness,depressive symptoms,and sleep quality were assessed using a short-form University of California Los Angeles Loneliness Scale(ULS-8),the 10-item version of Center of Epidemiologic Studies Depression Scale(CESD-10),and the Pittsburgh Sleep Quality Index(PSQI),respectively.The Spearman rank correlation coefficient was employed to assess the correlations among social sleep,loneliness,and depression symptoms.Generalized structural equation modeling was used to assess the mediating effect of loneliness between sleep and depressive symptoms.Results Of the 1377 participants,32.03％(441)experienced loneliness and 30.57％(421)had depressive symptoms,with the median and interquartile range of their sleep quality being 6(3,9).Correlation analysis revealed statistically significant associations between sleep quality,loneliness,and depressive symptoms(P＜0.001).Generalized structural equation modeling analysis revealed that loneliness had a partial mediation effect on the association between sleep quality and depressive symptoms(b=0.075;95％CI,0.025-0.125;P＜0.05),accounting for 44.38％of the total effect(95％CI,0.258-0.630;P＜0.001).Conclusion Poor sleep quality is associated with a higher risk of depressive symptoms in community-dwelling older adults,with loneliness mediating the association.Further research on improving the sleep quality to mitigate depressive symptoms in older adults is warranted.Special attention should be given to older adults experiencing both poor sleep and loneliness.

Objective To investigate the application of cardiovascular magnetic resonance feature tracking(CMR-FT)in assessing myocardial strain in dilated cardiomyopathy(DCM)patients residing at high altitudes.Methods We retrospectively enrolled 29 DCM patients living at high altitudes(DCM-H),27 DCM patients living in a low-altitude plain environment(DCM-P),23 healthy volunteers living at a high altitude(HV-H),and 24 healthy volunteers living in a low-altitude plain environment(HV-P).All subjects underwent cine MRI scanning using a 3.0T rapid steady-state free precession sequence.The CMR images thus acquired were analyzed using cvi42,a post-processing software,to obtain left ventricular function and myocardial strain parameters.Results Compared with the HV-H group,the DCM-H group showed higher left ventricle end-diastolic volume(LVEDV)and left ventricle end-systolic volume(LVESV),and lower left ventricular ejection fraction(LVEF)and stroke volume(LVSV)(all P＜0.01).No significant difference was observed in cardiac function between the DCM-H and DCM-P groups(all P＞0.05).The absolute values of global radial strain(GRS),global circumferential strain(GCS),and global longitudinal strain(GLS)in the DCM-H group were lower than those in the HV-P group([14.5±6.5]％vs.[34.2±10.7]％,[-11.1±4.4]％vs.[-19.9±2.8]％,and[-7.7±3.2]％vs.[-13.6±4.1]％,respectively),with the differences being statistically significant(all P＜0.001).The DCM-H group had higher absolute GRS,GCS,and GCS values than the DCM-P group did([14.5±6.5]％vs.[7.0±2.7]％,[-11.1±4.4]％vs.[—5.4±2.2]％,and[—7.7±3.2]％vs.[—4.3±1.7]％,respectivley,all P＜0.01).Conclusion Myocardial strain in DCM patients living at a high altitude is lower than that in healthy volunteers living at a high altitude,but higher than that in DCM patients living in a low-altitude plain environment.CMR-FT can be used to quantitatively assess myocardial contractility in DCM patients living at a high altitude,showing promise for clinical application.

Objective:To investigate the impact of evaluating the alcohol intake on all-cause mortality in patients with metabolic-associated fatty liver disease（MAFLD）and metabolic dysfunction and alcohol-related liver disease（MetALD）.Method:The retrospective study included patients aged 20 to 74 years with hepatic steatosis diagnosed by ultrasound，with data from the Third National Health and Nutrition Examination Survey（NHANES III）between 1988 and 1994. Participants were categorized into light，moderate，and heavy drinking groups according to daily alcohol intake. Multivariable-adjusted hazard ratios（aHR）and their 95% confidence intervals（ CI）were calculated by Cox proportional risk regression modeling to assess the effect of alcohol intake on all-cause mortality. Results:A total of 2 322 patients were included in the study. Males accounted for 50.2%（1 166/2 322），with a age of 42.0（31.3，57.0）years，a median follow-up of 316.0（270.0，337.0）months，and an all-cause mortality rate of 1.48% per person-year. There were 1，763 cases in the light drinking group，333 in the moderate drinking group，and 226 in the heavy drinking group.The all-cause mortality rates for patients in the three drinking groups were 1.38%，1.67%，and 2.10% per person-year，respectively. The moderate（a HR=1.37，95% CI：1.12 to 1.67， P=0.002）and heavy（a HR=1.45，95% CI：1.17 to 1.80， P=0.001）drinking groups were independently associated with increased all-cause mortality following covariate adjustment. There was a difference in all-cause mortality for alcohol intake in non-type 2 diabetes mellitus（T2DM）patients under 60 years of age（ P<0.05），but the difference was not statistically significant between non-T2DM patients over 60 years of age and T2DM patients of all ages（ P>0.05）according to the analysis of diabetes status and age subgroups. Conclusion:Alcohol intake has a dose-dependent negative effect on patients with MAFLD and MetALD. The risk of all-cause mortality increased significantly with increasing alcohol intake.

Objective:To investigate the efficacy of fibrosis-4 index (FIB-4), NAFLD fibrosis score (NFS), aspartate aminotransferase to platelet count ratio (APRI), liver stiffness value (LSM), and Agile 3+ score and their combined model in predicting advanced-stage liver fibrosis in patients with chronic hepatitis B (CHB) combined with metabolic-associated fatty liver disease (MAFLD).Methods:A multicenter retrospective cohort study was conducted on the BMOVE population.Nine hundred twenty CHB cases combined with MAFLD who underwent liver biopsy at seven medical centers in China from April 2006 to December 2023 were included. The patients were divided into advanced-stage liver fibrosis (159 cases) and non-advanced-stage liver fibrosis (761 cases) according to the Scheuer's scoring system.The area under the receiver operating characteristic curve (AUROC), decision curve, and calibration curve analysis were used to evaluate the efficacy of the firbrosis-4 index (FIB-4) score, NFS score, APRI index, LSM, and Agile 3+ score and their combined model in predicting advanced-stage fibrosis. The liver fibrosis grade of all patients was diagnosed by liver biopsy. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of each scoring model and combined model, as well as the proportion of correctly classified patients, were calculated based on different cutoff values.Results:AUROC analysis showed that Agile 3+ (0.814, 95% CI: 0.787-0.838) and LSM (0.805, 95% CI: 0.778-0.829) had similar accuracy and were superior to FIB-4 (0.721, 95% CI: 0.691-0.749), NFS (0.687, 95% CI: 0.656-0.716) and APRI ( 0.689, 95% CI: 0.658-0.718); however, HBV DNA level and HBV e antigen status had no effect on this outcome. Decision curve analysis showed that interventions based on LSM and Agile 3+ had provided higher net benefits compared with serological scores. Calibration curves showed that Agile 3+ had better predicitive accuracy than all other models. Agile 3+ had the highest PPV (0.54), minimal uncertainty interval (11.6%), and the highest proportion of correctly classified patients (76%); followed by LSM (PPV: 0.43, uncertainty interval: 15.5%, correct classification rate: 66%), and FIB-4 (PPV: 0.42, uncertainty interval: 26.1%, correct classification rate: 62.6%) in terms of identifying advanced-stage liver fibrosis. Combined model analysis demonstrated that FIB-4 combined with Agile 3+ had improved the correct classification rate and reduced the proportion of missed patients compared with FIB-4 combined with LSM. Conclusion:The Agile 3+ score is superior than LSM, FIB-4, NFS, and APRI index at identifying advanced-stage fibrosis in patients with CHB combined with MAFLD. This study supports the use of FIB-4 index combined with Agile 3+ for risk stratification in patients with CHB combined with MAFLD.

Objective To investigate the association of ondansetron use with short-term mortality risk and long-term mortality risk in patients with cerebrovascular disease.Methods Clinical data of patients with cerebrovascular disease admitted to the intensive care unit(ICU)between 2008 and 2022 from the MIMIC-Ⅳ database were retrospectively collected.All enrolled subjects were divided into an ondansetron group and a non-ondansetron group according to whether they had used ondansetron during their hospitalization.The differences in clinical indicators between the two groups were equalized using a 1∶1 propensity score matching(PSM)method.Kaplan-Meier survival analyses were employed to compare the differences in survival rates between the two groups at ICU,hospital,30-and 90-day,respectively.Cox proportional-hazards regression models were employed to analyze the associations between ondansetron use and ICU,hospital,and 30-and 90-day all-cause mortality in critically ill patients with cerebrovascular disease.Results The study included 9,198 patients with cerebrovascular disease,including 3,514 in the ondansetron group and 5,684 in the non-ondansetron group.Pre-matched baseline data showed that the overall ICU,hospital,and 30-and 90-day mortality rates in the ondansetron group were 7.0％,12.4％,15.9％,and 21.3％respectively,while those in the non-ondansetron group were 11.0％,17.2％,22.3％and 27.9％respectively.After 1∶1 PSM equalization of baseline data,a total of 3,239 pairs were successfully matched.Based on the matched data,Kaplan-Meier survival analyses showed higher survival rates of ICU(P＜0.001),hospital(P＜0.001),30 d(P＜0.001),and 90 d(P＜0.001)in the ondansetron group compared to the non-ondansetron group.In Cox proportional-hazards analysis,after adjustment for potential confounders,the hazard ratios(HR)in the ondansetron group relative to the non-ondansetron group were 0.60[95％CI(0.51,0.71),P＜0.001]for ICU mortality,0.73[95％CI(0.64,0.83),P＜0.001]for hospital mortality,0.76[95％CI(0.67,0.85),P＜0.001]for 30 d mortality,and 0.81[95％CI(0.73,0.89),P＜0.001]risk ratio for 90 d mortality.Conclusion The use of ondansetron may significantly decrease the ICU,hospital,30 d and 90 d risk of mortality in patients with severe cerebrovascular disease.

Objectives To investigate the clinical efficacy on combined application of ear canal injected administration dispenser and triamcinolone acetonide econazole nitrate cream in the treatment of mycosis externa.Methods Clinical data of 130 patients(166 ears)diagnosed with mycosis externa from January 2023 to December 2023 were collected and randomly divided into two groups.In the observation group,65 cases(86 ears)were treated with ear canal injected administration dispenser combined with triamcinolone acetonide econazole nitrate cream,while in the control group,65 cases(80 ears)applied clean cotton swabs with triamcinolone acetonide econazole nitrate cream to the external auditory canal by themselves to treat mycosis externa.All the patients were treated for 4 weeks and followed up for half a year.The clinical efficacy,recurrence rate and adverse reactions were statistically analyzed and compared.Results The total effective rate of the observation group was 97.67%,which was significantly higher than that of the control group was 73.75%,there was a significant difference between the two groups(P<0.05).There were no obvious adverse reactions in either group.No obvious recurrence was observed in the recovered patients of both groups during the follow-up period.Conclusion The efficacy of combined of ear canal injected administration dispenser and triamcinolone acetonide econazole nitrate cream in the treatment of mycosis externa is significant.Compared with the traditional way of medicine application,the adverse reactions are less.It can improve the cure rate and reduce the recurrence rate,which is worthy in clinical application.
