OBJECTIVE To provide a basis for aligning Chinese pharmacoeconomic research on heart failure （HF） with international standards. METHODS A qualitative comparison o f domestic and global HF pharmacoeconomic studies was conducted across four dimensions： research methods and model application， research perspectives and endpoints， data sources and parameter selection， and policy translation and practical impact. RESULTS & CONCLUSIONS Global studies predominantly utilize long-term dynamic models， societal perspectives， real-world data integration， and directly inform reimbursement decisions. Conversely， domestic research often relies on short-term simplified models， a single healthcare system perspectives， literature-derived data， and individual medicine recommendations. Future domestic studies should transition to long-term dynamic modeling， develop localized disease-specific utility databases via big data， establish reimbursement-linked closed-loop mechanisms， and foster multidisciplinary collaboration to optimize healthcare resource allocation.

Objective:To observe the effect of contralateral needling to regulate tendons and circulate Qi combined with Maitland joint mobilization on ankle joint function and the peri-ankle muscle groups in patients with chronic ankle sprain.Methods:A total of 77 patients with chronic ankle sprain,meeting the inclusion criteria,were randomly divided into a control group(38 cases)and an observation group(39 cases).The control group received conventional acupuncture treatment,while the observation group received contralateral needling to regulate tendons and circulate Qi combined with joint mobilization.Both groups were treated once daily for two consecutive courses.The American Orthopaedic Foot&Ankle Society(AOFAS)ankle-hindfoot scale was used to assess ankle joint function in the two groups,and the biomechanical model of skeletal muscles of lower limbs(Gait2392_simbody)was used to evaluate the muscle strength of the peri-ankle muscle groups.Results:The total effective rate in the observation group was 94.9%,significantly higher than the 79.0%in the control group(P<0.05).After treatment,the AOFAS ankle-hindfoot scores in both groups increased compared to their respective pre-treatment scores(P<0.05),and the scores in the observation group were higher than those in the control group(P<0.05).After treatment,the maximum muscle strength values of the medial and lateral heads of the gastrocnemius,tibialis posterior,and flexor hallucis longus in both groups increased compared to their respective pre-treatment values(P<0.05),and the values in the observation group were higher than those in the control group(P<0.05).The maximum muscle strength values of the soleus and flexor digitorum longus in both groups decreased compared to their respective pre-treatment values(P<0.05),and the values in the observation group were lower than those in the control group(P<0.05).The maximum muscle strength values of the extensor hallucis longus and tibialis anterior in both groups increased compared to their respective pre-treatment values(P<0.05),and the values in the observation group were higher than those in the control group(P<0.05).The visual analog scale(VAS)score in both groups decreased compared to their respective pre-treatment score(P<0.05),and the score in the observation group was lower than that in the control group(P<0.05).Conclusion:Either the combined therapy(contralateral needling to regulate tendons and circulate Qi combined with joint mobilization)or the conventional acupuncture alone can alleviate pain,improve ankle joint function,and enhance the muscle strength of the peri-ankle muscle groups in patients with chronic ankle sprain,but the combined therapy shows superior efficacy.

Objective To determine the optimal extraction process for kaempferol from Alpinia officinarum Hance and to investigate its antioxidant activity.Methods Based on single-factor experimental data,this study employed the Box-Behnken central composite design and response surface methodology(RSM),combined with high-performance liquid chromatography(HPLC),to plot response surface and contour maps using kaempferol content as the response value.The optimal parameters for ethanol concentration,solid-liquid ratio,extraction time,and extraction temperature were selected.The antioxidant activity of kaempferol was comprehensively evaluated by calculating the radical scavenging rate using the DPPH radical scavenging assays.Results The optimal extraction conditions were determined to be an ethanol concentration of 84%,a solid-liquid ratio of 1∶80,an extraction time of 2 hours,and an extraction temperature of 82℃.Under these conditions,the kaempferol content extracted from Alpinia officinarum Hance reached 0.034 16%.In the DPPH radical scavenging assay,the extract showed a scavenging rate of 91.20%at a concentration of 1 mg/mL.Conclusion The optimized extraction process for kaempferol from Alpinia officinarum Hance was obtained using the Box-Behnken response surface design method,and this process is practical and feasible.The DPPH radical scavenging assay demonstrated that kaempferol from Alpinia officinarum Hance possesses antioxidant activity.

Mental disorders frequently co-occur with other physical illnesses,becoming one of the leading causes of disability worldwide.Early diagnosis and intervention are crucial for the effective management of these disorders.Currently,biomarker studies on mental disorders predominantly concentrate on genes,blood indicators,and imaging features of the brain.There is a growing interest in objective phenotypic markers as a research focus.It is established that the retina is part of the central nervous system(CNS),which extends from the mesencephalon and develops concurrently with the brain during the embryonic period.Given the overlapping pathophysiological mechanisms between neurodegenerative diseases and mental disorders,studying the structural and functional changes in the inner layers of the retina has emerged as a new direction in mental health research.The advent of optical coherence tomography(OCT)has enabled microscopic imaging of retinal structures.OCT is capable of objectively quantifying the retinal sub-layers and offers the advantages of being non-invasive,non-contact,and high-resolution.The use of OCT to explore structural changes in the retina among individuals with schizophrenia,bipolar disorder,major depression and other psychiatric disorders has been well documented;however,there is a paucity of reviews on this topic.This review summarizes current research on retinal structural alterations in patients with mental disorders,and the results demonstrate reduced thickness in certain sub-layers of the retina structure in patients with several mental disorders,which supports that the retina structure has the potential to be a biomarker for mental disorders and offers a novel avenue for research in the diagnosis and treatment.

Objective To investigate the drug-drug interaction between donepezil hydrochloride and moxifloxacin hydrochloride during combined administration through in vitro liver microsomal metabolism and changes in pharmacokinetic characteristics in rats.Methods A rat liver microsomal incubation system was constructed and optimized.Liquid chromatography-tandem mass spectrometry(LC-MS/MS)analysis of donepezil hydrochloride and high-performance liquid chromatography(HPLC)analysis of moxifloxacin hydro-chloride were performed.The pharmacokinetic and metabolic characteristics of the two drugs,alone and in combination,were compared in vitro using rat liver microsomes and in vivo using rats.Results In the liver microsomal system,the half-life(T1/2)of donepezil hydro-chloride in the combined administration 1 group was prolonged by 29.892％(P＜0.01)and the intrinsic clearance(CLint)was reduced by 23.194％(P＜0.01)compared with the donepezil hydrochloride group.Conversely,the metabolic parameters of moxifloxacin hydrochlo-ride in the combined administration 2 group did not differ significantly from that of the moxifloxacin hydrochloride group(P＞0.05).In the in vivo study,the AUC0～t and AUC0～∞ of donepezil hydrochloride in the combined administration 1 group increased by 44.259％and 44.496％,respectively,maximum plasma concentration(Cmax)increased by 117.723％,T1/2 was prolonged by 98.063％,and CLint was reduced by 35.293％,compared with that in the donepezil hydrochloride group.Moreover,the differences were all statistically significant(P＜0.05).The in vivo study findings were consistent with the results of the in vitro study.Conclusion A drug-drug interaction occurs when moxifloxacin hydrochloride is used in combination with donepezil hydrochloride.Moxifloxacin hydrochloride promotes the absorption of donepezil hydrochloride,inhibits its metabolism,slows its CLint,and increases donepezil exposure in the body.

Objective·To investigate the longitudinal changes in amygdala and hippocampal subfield volumes before and after transcranial magnetic stimulation(TMS)treatment in patients with major depressive disorder(MDD)and explore their correlation with the antidepressant and anxiolytic efficacy of TMS.Methods·A total of 58 patients diagnosed with MDD at Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,were included in this study between January 2018 and August 2023.Clinical depressive and anxiety symptoms were assessed by using the Hamilton Depression Scale(HAMD),Montgomery-Asberg Depression Rating Scale(MADRS),and Hamilton Anxiety Scale(HAMA)at baseline and post-TMS treatment.Patients underwent a baseline magnetic resonance imaging(MRI)scan followed by TMS treatment targeting the left dorsolateral prefrontal cortex(DLPFC)at a frequency of 10 Hz,totaling 20 sessions.A follow-up MRI scan was conducted on the same day the TMS treatment concluded.Amygdala and hippocampal subfield volumes were segmented and calculated by using FreeSurfer v6.0.0 software.Longitudinal changes in the subfield volumes were analyzed with two-way analysis of variance.Controlling for age,sex,and intracranial volume,partial correlation analysis was conducted between subfield volumes and baseline clinical scores.The association between the rate of volume change in brain regions with significant volume changes and symptom improvement(reduction in HAMD,MADRS,and HAMA scores)was evaluated.Results·Following TMS treatment,a significant increase in the volume of the right amygdala central nucleus was observed(t=-2.441,P=0.018).While the volumes of bilateral hippocampal fimbria decreased,the volumes of most hippocampal subfield and the total hippocampus increased(P<0.05).No significant correlations were found between baseline amygdala or hippocampal subfield volumes and clinical depressive and anxiety symptoms.However,only in patients who responded effectively to TMS treatment,a positive correlation was found between the volume change rate of the left hippocampal tail and reductions in anxiety symptoms(HAMA:r=0.334,P=0.044).Conclusion·High-frequency TMS targeting the left DLPFC may induce volume increases in the right amygdala central nucleus and specific hippocampal subfields.Additionally,the volume change rate of the left hippocampal tail is associated with anti-anxiety effects in TMS responders,suggesting that high-frequency TMS targeting the left DLPFC may induce neuroplastic changes in the central nucleus of the right amygdala and key subfields of the hippocampus.

Objective:To explore latent categories of death literacy among oncology nurses and analyze their influencing factors to inform the development of targeted interventions.Methods:Convenience sampling was used to select 560 oncology nurses from three ClassⅢ Grade A hospitals in Zhengzhou City, Henan Province, from June to July 2024 for the study. General Information Questionnaire, Death Literacy Index, Self-Competence in Death Work Scale, and Hospice Care Environment Scale were used to conduct the survey. Oncology nurses' death literacy categories were explored using latent profile analysis, and factors influencing each category were explored using unordered multicategorical Logistic regression analysis.Results:The 560 oncology nurses' death literacy were categorized into three profiles of low-level death literacy group (31.8%), medium-level death literacy group (50.7%), and high-level death literacy group (17.5%). Unordered multicategorical Logistic regression analysis showed that receiving death education and training since work, self-assessment of psychological status, self-competence in death work, and evaluation of the hospice care environment were influencing factors in the latent category of death literacy among oncology nurses ( P<0.05) . Conclusions:There is group heterogeneity in death literacy among oncology nurses, which is influenced by a variety of factors. Nursing managers can provide targeted interventions for oncology nurses based on different latent categories to improve their death literacy.
