Lipocalin-2 (LCN2), a member of the human lipocalin family, has been demonstrated to be closely associated with diabetes, cardiovascular diseases, and renal disorders. Recent studies have indicated that LCN2 plays a significant regulatory role in the pathogenesis and progression of various neurological diseases by mediating pathways such as inflammation, oxidative stress, and ferroptosis. This article reviews the research advancements on the mechanism of LCN2 in neurological disorders, including cerebrovascular diseases, cognitive impairment disorders, Parkinson's disease, depression, and anxiety disorders, aiming to enhance clinical understanding.

OBJECTIVE To analyze the efficacy and safety of luspatercept in the treatment of myelodysplastic syndromes （MDS） anemia， and provide reference for clinical medication. METHODS The literature related to luspatercept for MDS anemia in PubMed， Cochrane Library， Embase and Web of Science were searched by computer， and the search time was from the establishment of the database to January 2024. The quality of literature was evaluated after they were screened according to inclusion and exclusion criteria， the single-group rate meta-analysis and sensitivity analysis were performed by using RevMan 5.4 software， and the subgroup analysis was conducted. RESULTS A total of 756 patients in 9 articles were included in this study. The results of meta-analysis showed that the proportion of MDS patients who reached ≥8 weeks of red blood cell transfusion independence （RBC-TI） was 46% after using luspatercept [95%CI （0.28， 0.64）， P＜0.000 01]. The proportion of MDS patients whose hematological improvement in erythrocyte （HI-E） was 59% [95%CI （0.43， 0.74）， P＜0.000 01]. Among them， 5 articles reported that the proportion of MDS patients with grade 3-4 adverse reactions was 14% [95%CI （0.07， 0.22）， P＝0.000 2]， and the poor general condition， infection， blood and lymphatic system disease were the common adverse reactions. Subgroup analysis showed that the source of heterogeneity was the blood transfusion burden in the proportion of MDS patients with RBC-TI≥8 weeks， and the source of heterogeneity was the 0931-8356251。revised international prognostic scoring system （IPSS-R） risk grade， SF3B1 mutation status and blood transfusion burden in the proportion of MDS patients with HI-E. Sensitivity analysis showed that the results of this study were stable. CONCLUSIONS Luspatercept can significantly improve blood transfusion dependence， reduce blood transfusion burden and promote hematology improvement in MDS patients. But attention should be paid to the occurrence of grade 3-4 adverse events； adverse events such as poor general condition， infection， blood and lymphatic system diseases are more common.

Alzheimer's disease(AD), the most common neurodegenerative disease, has shown an increasing incidence among younger people. With the onset of disease, most patients' cognitive function will show a progressive decline, bringing a heavy burden to the society and the family. Studies have shown that fibroblast growth factor (FGF) may be involved in the pathogenesis of AD through multiple mechanisms. This article reviews the mechanism of FGF in AD, with the hope of providing new ideas for elucidating the pathogenesis and early diagnosis of AD.

Objective　To analyze and visualize the epidemic changes of schistosomiasis in Wuhan from 2013 to 2022 based on a geographical information system (GIS), providing references for further schistosomiasis control activities. Methods　According to the historical data of the annual reports of schistosomiasis screening and street-level vector map of Wuhan City from 2013 to 2022, a spatial database of epidemic information at the street level was established. The Joinpoint regression model was utilized to analyze the trend of phased changes in blood positivity rate for schistosomiasis. ArcMap 10.8 was employed for the spatial visualization of the positive rate of serological tests for schistosomiasis among the screened population in the endemic areas of Wuhan over the past decade, as well as conducting hot spot analysis (Getis-Ord Gi*) to explore the spatial clustering relationship and spatiotemporal trends. Heatmaps were generated to reflect the changes in the positive rate of blood tests for schistosomiasis over a decade in various streets, and the areas were classified by the ward’s method of hierarchical clustering using the sum of squared deviations. Results　Over the past decade, the overall annual positive rate of schistosomiasis screening in Wuhan declined from 2.23% in 2013 to 0.47% in 2022, showing a general downward trend. The Joinpoint regression model analysis of the blood positive rate indicated the presence of one connection point in 2015; from 2013 to 2015, the annual percent change (APC) of the positive rate was 2.17%, showing an upward trend (P>0.05); from 2015 to 2022, the APC was -23.34%, indicating a downward trend (P<0.05). The map of positive street-level schistosomiasis screening rates for 2013-2022 shows that the positive rate count on the streets of Caidian District and Hannan District in southwestern Wuhan and Huashan Street on the east side, had a significant decrease over the ten years, while the rate in the streets under the jurisdiction of Dongxihu District in the west showed an increase. The hot spot analysis graph revealed that hot spots of the positive rate in Wuhan shifted from the southwest to the west beginning in 2018. The heatmap indicated the largest disparity in trend changes, with the most noteworthy decline in streets under Caidian District and an increasing trend in the streets under Dongxihu District. Conclusions　The overall epidemic situation of schistosomiasis in Wuhan is on a downtrend, although the positive rate of blood tests has increased in some areas. This has been attributed to a reduction in the total number of people participating in the blood tests and the slow decrease of antibodies in certain patients who were repeatedly sampled for testing. It is important to further strengthen the construction of monitoring capabilities, improve the sensitivity of monitoring systems, identify potential risks promptly, and handle them properly.

Objective:To analyze the molecular evolutional characteristics of the hemagglutinin and neuraminidase genes of influenza A (H3N2) viruses isolated in Yancheng from 2022 to 2024.Methods:The throat swab specimens of influenza-like illness ( ILI) from sentinel surveillance hospital and outbreak sites were detected using the method of real time Rt-qPCR. The influenza A(H3N2) viruses were isolated using MDCK cells culture method from April 2022 to Marh 2024. The strains isolated from 2022 to 2024 were selected randomly and their sequences of the HA1 and NA genes were amplified through one step RT-PCR method and the PCR products were sequenced.The nucleotide and amino acid site variations and evolutionary characteristics of the genes were analyzed using relevant bioinformatics software. The mutations of genes and nucleic acid locus were analyzed and the evolutional trees were generated using bioinformatics software.Results:A total of 5 020 samples were collected between April 2022 and March 2024, the positive detection rate of influenza virus nucleic acid was 18.59%(933/5 020).The winter and spring influenza peaks were obvious in the two monitoring seasons from April 2022 to March 2024. Among them, the summer influenza peak was obvious in the monitoring season from April 2022 to March 2023, and the H3N2 subtype influenza virus was the dominant epidemic strain in the two monitoring seasons. Genetic evolution tree displayed: the clustering relationships of the respective branches of HA1 and NA genes of 32 strains isolated in Yancheng were basically the same.The HA1 and NA genes of 24 strains isolated from 2023-2024 in Yancheng and the 2022-2024 Northern Hemisphere vaccine strain A/Darwin/9/2021 (H3N2) were located in the 3C.2a1b2a.2a.3a.1 evolutionary lineage, while the 8 strains isolated in the 2022 in Yancheng and the 2021-2022 Northern Hemisphere vaccine strain A/Cambodia/e0826360/2020 (H3N2) were located in the 3C.2a1b.2a.1a evolutionary lineage.The 6 strains (A/JSTH/11735/2023, A/JSTH/11788/2023, A/JSTH/11974/2023, A/JSYD/353/2023, A/JSYD/354/2023, A/JSTH/138/2023) all exhibited variations in the F79L, N122D, P239S, and K276E amino acid sites, which were present in both sporadic and outbreak strains. Because the strains of the antigen epitopes, receptor binding sites and glycosylation sites in the HA1 genes had a certain degree of variations in Yancheng in the 2022-2024 year, the immunogenicity matching between the 24 strains isolated in the 2023-2024 and the Northern Hemisphere vaccine strain A/Darwin/9/2021 was good, while the immunogenicity matching between the 8 strains isolated in the 2022 and the Northern Hemisphere vaccine strain A/Cambodia/e0826360/2022 was good; 32 strains isolated from 2022 to 2024 had no mutations in catalytic residues and drug resistant sites of NA genes.Conclusion:These result indicated that the HA1 and NA genes of influenza A/H3N2 viruses circulated in Yancheng city from 2022 to 2024 are changed gradually.The accumulation of these mutations would result in antigenic drift of influenza A(H3N2) viruses and increase the mismatching of the recommended vaccine strain.Compared with the vaccine strain A/Darwin/9/2021(H3N2), the strains isolated in the 2022 had substantially result in antigenic drift on the whole.The influenza A(H3N2) viruses surveillance should be strengthened to find the new mutant of virus in time.

Objective To observe the value of 18F-fluoro-dihydroxy-phenylalanine(18F-FDOPA)PET/CT for evaluating the efficacy of radiochemotherapy for advanced glioma.Methods Data of 84 patients with advanced glioma who received precision radiotherapy combined with synchronous chemotherapy were retrospectively analyzed.The patients were divided into effective group(complete remission+partial remission+stable disease,n=60)and ineffective group(progressive disease,n=24)according to the efficacy of radiochemotherapy.18F-FDOPA PET/CT metabolic parameters of tumors,including tumor metabolic tumor volume(MTV),maximum standard uptake value(SUVmax)and mean standard uptake value(SUVmean)were compared between groups,also before and after radiochemotherapy within groups.Spearman correlation analysis was used to observe the correlations of metabolic parameters and the efficacy of radiochemotherapy.Results After radiochemotherapy,MTV,SUVmax and SUVmean of tumors in effective group were lower than those of tumors in ineffective group(all P＜0.05).Significant differences of metabolic parameters were found before and after radiochemotherapy in effective group(all P＜0.05).MTV,SUVmax and SUVmean of advanced glioma were negatively correlated with the efficacy of radiochemotherapy(r=-0.63,-0.52,-0.50,P＜0.001,P=0.007,P=0.010).Conclusion 18F-FDOPA PET/CT was helpful for evaluating the efficacy of radiochemotherapy for advanced glioma.

Myelodysplastic syndrome(MDS)is a heterogeneous myeloid tumor that originates from hematopoietic stem cells(HSCs)and is associated with a high risk of progression to acute myeloid leukemia(AML).Studies have shown that 90%of patients with MDS have gene mutations,of whom approximately 25%have SF3B1 mutations.In patients with MDS carrying this mutation,the TGF-β pathway is upregu-lated,inducing cell cycle arrest and thereby leading to erythroid ineffective hematopoiesis and pathological hematopoiesis.Luspatercept can be used as a ligand trap to capture TGF-β ligands,inhibit SMAD2/3 pathway activation,downregulate TGF-β pathway,and promote ad-vanced red blood cell maturation.Currently,it has been approved by the Food and Drug Administration(FDA)for the treatment of anemia in patients with low-risk MDS,and studies have shown that the response rate is higher in patients with SF3B1 mutations.This article will re-view the current status of luspatercept in the treatment of SF3B1 mutation-related MDS;it will also analyze its effectiveness and safety and provide therapeutic strategies for clinical use.

Objective To investigate the status of application of the central venous access in the departments of hematology to develop targeted administrative strategies and provide evidence for management.Methods A self-de-signed questionnaire was applied and convenience sampling was adopted in 93 hematology departments from 48 hospitals in 19 provinces(autonomous regions,municipalities).Results A total of 91 valid questionnaires were col-lected,with a valid questionnaire response rate of 97.85％.Among the 91 hematology departments,91(100％),73(80.22％),and 68(74.73％)carried out PICC,central venous catheter,and totally implantable access port catheteriza-tion,respectively.In the evaluation of blood test indicators before central venous access,the items with a higher e-valuation proportion were platelet count(100％)and D-dimer concentration(87.91％),while the evaluation proportion of other items was＜85％.When PICC catheterization,97.80％of hematology departments prefer basilic vein;83.52％of hematology departments used zone insertion method;95.60％of hematology departments had a skin disinfection range of ≥20 cm;98.90％of hematology departments had catheterization under ultrasound guidance;67.03％and 96.70％of hematology departments used the intracardiac electrocardiogram method or ultrasound assisted localiza-tion,postoperative X-ray localization;12.09％and 53.85％of hematology departments carried out tunnel catheteriza-tion and blunt separation expansion techniques,respectively.In terms of maintenance of central venous access de-vices,82.42％of hematology departments used disposable specialized maintenance kits;61.54％of hematology de-partments used transparent patches to fix PICC;45.21％of hematology departments used suture to fix central venous catheters;24.18％of hematology departments used cotton swabs to disinfect infusion joints;60.44％of hematology departments did not use disposable infusion joint disinfection cap;74.73％of hematology departments used gauze compression to prevent puncture site bleeding;only 6.59％hematology departments used antibacterial dressings con-taining chlorhexidine to prevent puncture site infections.In terms of quality management of central venous access devices,94.51％and 86.81％of hematology departments regularly conducted quality inspections of central venous access,and collected,calculated and analyzed relevant data.50.55％of hematology departments conducted complica-tion risk assessments,and 10.99％of hematology departments had established information management systems for venous therapy.Conclusion The implementation rate of PICC catheterization in the hematology department was relatively high,and the insertion operation basically meets the standard requirements.The evaluation before central venous access catheterization was relatively completed,and the maintenance and management are relatively stan-dardized.However,the evaluation of blood test indicators before the placement of central venous access urgently needs to be standardized and unified.When PICC catheterization,attention should be paid to the application of new technologies,and the information management of venous therapy needs to be improved.

Objective To evaluate and integrate the facilitators and barriers to adherence to diet or exercise interventions in patients with overweight or obesity.Methods PubMed,Web of Science,Embase,CINAHL,Cochrane Library,China National Knowledge Infrastructure,Wanfang,and VIP Chinese Biomedical Literature Database were searched by computer from the establishment of the database to October 14,2023.The 2016 edition of the Joanna Briggs Institute(JBI)evidence-based health care center qualitative research evaluation criteria was used to evaluate and integrate the included literature.Results A total of 19 studies were included,and 38 outcomes were distilled into 12 categories,and the results were consolidated into facilitators(disease threat perception,self-body perception,self-adjustment,sense of responsibility,social support)and barriers to intervention adherence(poor treatment benefit,low self-efficacy,lack of knowledge,competitive priorities,extemal environmental constraints,economic conditions,poor intervention design).Conclusion There are many facilitators and barriers of diet or exercise intervention perceived by patients.It is suggested that follow-up intervention research should be used as a reference to improve the treatment compliance of patients.
