OBJECTIVES: This systematic review examines recent pharmacoeconomic literature on denosumab' cost-effectiveness for bone metastasis treatment, providing evidence-based insights to guide healthcare policy decisions. METHODS: A comprehensive literature search was performed across Cochrane, PubMed, EMBASE (Ovid), CNKI, and Wanfang databases to identify original articles published between 2017 and 2023. Key words consisted of bone metastases, denosumab, and cost-effectiveness in the search strategy. The methodological quality of the included studies was assessed utilizing the revised Consolidated Health Economic Evaluation Reporting Standards (CHEERS 2022). Data was extracted regarding methodological characteristics and cost-effectiveness analyses. RESULTS: A total of 111 studies were retrieved, of which 6 met the inclusion criteria. All included studies were based on clinical trials and published literature data and exhibited high methodological quality. Up to 83% (5 out of 6) of comparisons demonstrated that denosumab was more cost-effective or dominant compared to zoledronic acid. The adjusted incremental cost-effectiveness ratios varied substantially by tumor type, ranging from CZK 436,339.09 to USD 136,234 per skeletal-related event avoided and from CZK 61,580.95 to USD 118,392.11 per quality-adjusted life year gained. CONCLUSIONS The majority of the included studies support denosumab as a more cost-effective treatment option for bone metastases in solid tumors compared to zoledronic acid. The application of CHEER (2022) enhances the reliability of pharmacoeconomic evaluations.

Aim To investigate the effects of edaravone(EDA)on depression-like behaviors in a rat model of post-stroke depression(PSD)and to explore the un-derlying mechanisms.Methods SD rats were ran-domly divided into:sham operation group(Sham),cerebral ischemia group(CI),post-stroke depression(PSD),fluoxetine(10 mg·kg-1)group,and EDA(5,15 mg·kg-1)group.A PSD rat model was estab-lished using the suture method combined with 56 d of chronic unpredictable mild stimulation.Drug treatment was given once daily for 28 d after stimulation.Body weight and sucrose water preference were measured during the stimulation period,and serum TNF-α,IL-1 β,IL-6,MDA,SOD levels,and hippocampal tissue HO-1 and GPX4 protein expression were detected at the end of stimulation.Results Compared with the sham group,the rat neurological function scores of the remaining groups increased(P＜0.01).Compared with the PSD group,EDA increased the body weight and sucrose water preference of the rats(P＜0.01),significantly decreased the serum TNF-α,IL-1β and IL-6 levels,decreased the MDA level,increased the SOD level(P＜0.01),and up-regulated hippocampal HO-1 and GPX4 protein expression(P＜0.01).Con-clusions EDA improves depression-like behaviors and inhibits peripheral inflammation and oxidative stress in-jury in PSD rats,and its mechanism may be related to the activation of HO-1/GPX4 pathway to inhibit oxida-tive stress.

Objective To compare the blood flow perfusion area in different retinal vascular plexuses between adults and children using swept-source optical coherence tomography angiography(SS-OCTA)and explore the correlation of the retinal blood flow perfusion area with spherical equivalent(SE)and axial length(AL).Methods A total of 112 partici-pants,including 58 children(116 eyes,aged 8-13 years)and 54 adults(108 eyes,aged 18-30 years),were recruited from Eye Hospital,Wenzhou Medical University from December 2020 to December 2024.Based on SE,these children and adults were further divided into the emmetropia(-0.50＜SE ≤+0.50 D),low myopia(-3.00＜SE≤-0.50 D),and moderate myopia(-6.00＜SE≤-3.00 D)groups.SS-OCTA was used to acquire the perfusion area data across retinal vascular layers.The inner vascular network of the retina was subdivided into the peripapillary radial vascular network,su-perficial vascular plexus(SVP),middle vascular plexus(MVP),and deep vascular plexus(DVP).The blood flow perfu-sion areas across retinal vascular layers were compared between adults and children.Pearson correlation analysis was per-formed to assess the correlation of the blood flow perfusion areas across retinal vascular layers with AL and SE in adults and children,respectively.Results SE was negatively correlated with AL in both adults and children(r=-0.781 and-0.667,respectively;both P＜0.001).The total inner retinal perfusion area was negatively correlated with AL in both adults and children(r=-0.239 and-0.299,respectively;both P＜0.05).In children,the perfusion area in the peripapil-lary radial vascular network,SVP,and DVP was negatively correlated with AL(r=-0.443,-0.315,and-0.220,respec-tively;all P＜0.05).In adults,the perfusion area in SVP,MVP,and DVP was negatively correlated with AL(r=-0.243,-0.230,and-0.364,respectively;all P＜0.05).Adults with low/moderate myopia exhibited a significantly larger perfu-sion area in the peripapillary radial vascular network compared with children with corresponding myopia levels,and the differences were statistically significant(both P＜0.001).Conclusion There were significant differences in the perfu-sion area of the peripapillary radial vascular network between adult and pediatric myopic patients.AL showed the strongest correlations with the perfusion area of the peripapillary radial vascular network in adults and the perfusion area of DVP in children,respectively,suggesting distinct effects of retinal vascular layers at different stages of ocular growth.

BackgroundMany studies have shown that patients with depressive disorder show impairments in prospective memory， while it is deemed necessary for facilitating their social reintegration， and the current research findings are inconsistent regarding the factors affecting prospective memory of patients with depressive disorder. ObjectiveTo explore the impact of target characteristics （emotional valence and salience） on prospective memory in patients with depressive disorder， so as to provide references for the training and recovery of prospective memory function in these patients. MethodsFrom January to December 2022， 53 patients with depressive disorder were recruited from the outpatient department of Inner Mongolia Autonomous Mental Health Center. Meanwhile， 45 healthy individuals were concurrently recruited from surrounding communities as control group. An experiment with a 2 （participant type： depressive disorder， healthy control） ×2 （target salience： salient， non-salient） ×3 （emotional valence： positive， neutral， negative） factorial design was conducted. The positive/neutral/negative emotional pictures from Chinese Affective Picture System （CAPS） were used for emotional stimulation. A dual-task experimental paradigm was adopted， and the response time and accuracy in prospective memory task and ongoing task were recorded for participants with different target characteristics. Results①In the prospective memory task， the main effect of participant type was statistically significant， with the depressive group showing lower accuracy （F=14.892， P<0.01） and longer response time （F=10.642， P=0.002） compared with control group. ② The main effect of target emotional valence on accuracy （F=7.575， P=0.001） and response time （F=3.196， P=0.044） in the prospective memory task was statistically significant. Simple effect analysis revealed that depressive group yielded a shorter response time and higher accuracy rate under negative conditions compared with positive and neutral conditions （P<0.05 or 0.01）. ③ The main effect of target salience on accuracy （F=6.659， P=0.012） and response time （F=10.106， P=0.002） in the prospective memory task was also statistically significant， with higher accuracy and shorter response time for salient targets compared with non-salient targets. ConclusionPatients with depressive disorder demonstrate preferential attention to and processing of negative stimuli in prospective memory tasks， while increasing target salience may facilitate spontaneous processing of prospective memory task in patients with depressive disorder. ［Funded by Inner Mongolia Health Commission Medical Health Science and Technology Project （number， 202202104）］

The neurophysiological mechanisms by which exercise improves cognitive function have not been fully elucidated. A comprehensive and systematic review of current domestic and international neurophysiological evidence on exercise improving cognitive function was conducted from multiple perspectives. At the molecular level, exercise promotes nerve cell regeneration and synaptogenesis and maintains cellular development and homeostasis through the modulation of a variety of neurotrophic factors, receptor activity, neuropeptides, and monoamine neurotransmitters, and by decreasing the levels of inflammatory factors and other modulators of neuroplasticity. At the cellular level, exercise enhances neural activation and control and improves brain structure through nerve regeneration, synaptogenesis, improved glial cell function and angiogenesis. At the structural level of the brain, exercise promotes cognitive function by affecting white and gray matter volumes, neural activation and brain region connectivity, as well as increasing cerebral blood flow. This review elucidates how exercise improves the internal environment at the molecular level, promotes cell regeneration and functional differentiation, and enhances the brain structure and neural efficiency. It provides a comprehensive, multi-dimensional explanation of the neurophysiological mechanisms through which exercise promotes cognitive function.
