Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Objective: To investigate the expression and functional role of FK506 binding protein 10 (FKBP10) in oral squamous cell carcinoma (OSCC), and to provide a research basis for the estimated prognosis and targeted therapy of OSCC. Methods: A total of 284 OSCC samples and 19 normal samples were selected from the Cancer Genome Atlas (TCGA) database, and diagnostic analysis was performed to determine mRNA expression. Survival analysis for FKBP10 and OSCC was conducted on a gene expression profile interaction analysis website. Real-time fluorescence quantitative PCR and Western Blot were used to detect the mRNA and protein expression of FKBP10 in four OSCC cell lines and SAS and SCC9 cells transfected with siRNA. The cell proliferation ability of FKBP10-silenced cells was detected using the CCK8 method, and the cell cycle distribution and apoptosis were detected by flow cytometry. Cell migration and invasion ability were detected through wound healing and invasion experiments. The expression changes of total protein and phosphatidylinositol 3-kinase (PI3K)-serine/threonine kinase (AKT) after FKBP10 silencing were analyzed by proteomics and Western Blot. Results: According to the analysis of gene expression levels, the mRNA expression level of FKBP10 in OSCC was significantly higher than that in normal tissues (P < 0.001). In terms of diagnosis, the expression level of FKBP10 has unique diagnostic value for OSCC (P < 0.05). The survival analysis of FKBP10 and OSCC showed that a high expression of FKBP10 led to a decrease in patient survival and poor prognosis (P < 0.05). The expression of FKBP10 mRNA and protein in OSCC cell lines was higher than that in normal oral keratinocytes (P < 0.001). Silencing FKBP10 can reduce the proliferation, invasion, and migration ability of SAS and SCC9 (P < 0.001), and also block their cell cycle in the G0/G1 phase (P < 0.001), with a significant increase in apoptosis (P < 0.05). Protein mass spectrometry and Western blot analysis revealed that FKBP10 silencing significantly downregulated the expression of multiple proteins in the RAP1 signaling pathway, mainly RAP guanine nucleotide exchange factor 1 (RAPGEF1) (P < 0.05) and the phosphorylation of PI3K-AKT proteins (P < 0.05). Conclusion FKBP10 is highly expressed in OSCC, leading to poor prognosis for patients. Downregulated FKBP10 expression can inhibit the proliferation, migration, and invasion ability of OSCC cells, hinder cell cycle progression, and promote apoptosis via the RAP1-PI3K-AKT axis. FKBP10 is a potential therapeutic target and prognostic biomarker for OSCC.

Background::The conversion of adenosine (A) to inosine (I) through deamination is the prevailing form of RNA editing, impacting numerous nuclear and cytoplasmic transcripts across various eukaryotic species. Millions of high-confidence RNA editing sites have been identified and integrated into various RNA databases, providing a convenient platform for the rapid identification of key drivers of cancer and potential therapeutic targets. However, the available database for integration of RNA editing in hematopoietic cells and hematopoietic malignancies is still lacking.Methods::We downloaded RNA sequencing (RNA-seq) data of 29 leukemia patients and 19 healthy donors from National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO) database, and RNA-seq data of 12 mouse hematopoietic cell populations obtained from our previous research were also used. We performed sequence alignment, identified RNA editing sites, and obtained characteristic editing sites related to normal hematopoietic development and abnormal editing sites associated with hematologic diseases.Results::We established a new database, "REDH", represents RNA editome in hematopoietic differentiation and malignancy. REDH is a curated database of associations between RNA editome and hematopoiesis. REDH integrates 30,796 editing sites from 12 murine adult hematopoietic cell populations and systematically characterizes more than 400,000 edited events in malignant hematopoietic samples from 48 cohorts (human). Through the Differentiation, Disease, Enrichment, and knowledge modules, each A-to-I editing site is systematically integrated, including its distribution throughout the genome, its clinical information (human sample), and functional editing sites under physiological and pathological conditions. Furthermore, REDH compares the similarities and differences of editing sites between different hematologic malignancies and healthy control.Conclusions::REDH is accessible at http://www.redhdatabase.com/. This user-friendly database would aid in understanding the mechanisms of RNA editing in hematopoietic differentiation and malignancies. It provides a set of data related to the maintenance of hematopoietic homeostasis and identifying potential therapeutic targets in malignancies.

Aim To study the permeability of salidro-side(Sal)to the blood brain barrier(BBB)by high-performance liquid chromatography electrospray ioniza-tion tandem mass spectrometry(UPLC-ESI-MS-MS),and to explore the target and mechanism of Sal in the treatment of ischemic stroke(IS)by network pharma-cology,molecular docking technique and animal exper-iment.Methods UPLC-ESI-MS/MS was used to study the BBB penetration of Sal.Multiple databases were used to predict the target of Sal and the disease target of IS,GO and KEGG enrichment analysis were performed and verified by molecular docking technique and animal experiments.Results After Sal adminis-tration to normal rats and MCAO rats,Sal prototype and the metabolite tyrosol were detected in plasma and brain tissue of rats.A total of 191 targets were identi-fied by network pharmacology,the enrichment analysis of GO mainly involved in the biological processes of proteolysis and positive regulation of cell migration,and the analysis of KEGG pathway suggested that PI3K-Akt,MAPK,FOXO and other signaling path-ways played a key role in the treatment of IS by Sal The results of molecular docking showed that Sal had good binding ability with the core target of docking,and the results of animal experiments showed that Sal could significantly improve the neurologic impairment of MCAO rats,the number of Nissl-positive cells in is-chemic side significantly increased,and the expression of VEGF,EGFR and IGF1 increased,while the ex-pression of IL-6 and MMP9 was inhibited.Conclu-sions Sal is able to penetrate the BBB and enter the central nervous system for its pharmacological effects.Network pharmacology predicts the core targets of Sal in the treatment of IS,including VEGFA,EGFR,IL-6,MMP9,IGF1,CASP3,ALB,SRC.The effects of Sal on some core targets can be verified by animal ex-periments,to provide a reference for further study of the mechanism of Sal in the treatment of IS.

Objective To compare the application effects of high-frequency electric surgical knife and scalpel in blepharoplasty.Methods A retrospective analysis was performed for 35 patients(70 eyes)who were admitted to the Shanghai Ninth People's Hospital,Shanghai JiaoTong University School of Medicine from January to July 2021,and one side eye was randomly selected as the high-frequency electric surgical knife group(operated by high-frequency electric surgical knife)and the other side eye as the scalpel group(operated by scalpel),with 35 eyes in each group.The effect of blepharoplasty in both eyes after surgery was evaluated.The swelling and ecchymosis of the patients were observed 1 day,1 week,1 month and 3 months after surgery.The Manchester scar scale(MSS)was used to evaluate the scarring of the patients 1 week,1 month and 3 months after surgery.The excised tissues were stained with HE staining and TUNEL staining to assess the degree of necrosis and the extent of thermal damage to the skin and muscle.Results There was no statistically significant difference in swelling,ecchymosis,pain or scarring after surgery between the two groups(P＞0.05).The eyelids of the high-frequency electrosurgical group showed coagulative necrosis of muscle tissue,and the scalpel group had almost no coagulative necrosis.There was statistically significant difference in the proportion of coagulable necrotic muscle after surgery between the two groups(P＜0.05),and the depth of thermal damage in the high-frequency electric surgical knife group was greater than that in the scalpel group(P＜0.05).Conclusion The high-frequency electric surgical knife in blepharoplasty is simple to operate,and safe to use,with timely intraoperative incision and coagulation,which can obtain good surgical field and effect.

Mytilus is one of bivalves with great economic and ecological values.The innate immune de-fense of Mytilus shows great significance in the study of marine biological immunology.Hemolymph is the main immune tissue for Mytilus.The Nanopore full-length transcriptome of Mytilus coruscus hemocytes,and the serum differential proteomics based on SDS-PAGE analysis were performed to identify key pro-teins involving in the immune response of Mytilus hemolymph in response of different bacteria and fungi stresses.A total of 44 proteins were identified in the serum induced by different microorganisms.Among them,26 proteins showed significant differential expression level in response to different microbial stres-ses,and their functions were involved in protein folding protection,cell autophagy and apoptosis regula-tion,reactive oxygen species production,energy metabolism regulation,cell detoxification,and immune regulation.The changes in expression levels of these proteins varied in response to different bacterial and fungal stresses,suggesting that Mytilus has different immune response strategies to different bacterial and fungal stresses.The results provide a new scientific basis for understanding the differential immune mech-anism of Mytilus innate immune system in response to different types of microbial invasion,as well as the screening of specific biomarker proteins for microbial infection,and provide ideas for the healthy develop-ment and disease prevention of shellfish aquaculture.

Objective:To investigate the prognostic significance of DTA(DNMT3A,TET2,ASXL1)gene mutations in patients with non-M3 acute myeloid leukemia(AML).Methods:The clinical data of 180 newly diagnosed AML patients hospitalized in the First People's Hospital of Changzhou from January 2018 to April 2022 were retrospectively analyzed.Next-generation sequencing technology was used to detect 150 gene mutations in the patients,and log-rank tests and Cox regression models were used to analyze the prognostic factors.Results:DTA gene mutations were detected in 83(46.1％)of 180 AML patients.Compared to patients without DTA mutations,patients with DTA mutations were significantly older(P＜0.001).The median overall survival(OS)time and disease-free survival(DFS)time in the DTA mutation group were significantly shorter than those in the group without DTA mutation(both P＜0.05).Multivariate analysis showed that age ≥ 60 years(P＜0.001),with DTA mutation(P=0.018),and intermediate-risk(relative to favorable-risk)(P=0.005)were independent risk factors for OS in AML patients.Conclusion:AML patients with DTA mutations are relatively older,with shorter median OS time and DFS time,and poor prognosis.

Objective: This study aimed to evaluate the effects of 2 endoscopic spine surgeries on the biomechanical properties of normal and osteoporotic spines. Methods: Based on computed tomography images of a healthy adult volunteer, 6 finite element models were created. After validating the normal intact model, a concentrated force of 400 N and a moment of 7.5 Nm were exerted on the upper surface of L3 to simulate 6 physiological activities of the spine. Five types of indices were used to assess the biomechanical properties of the 6 models, range of motion (ROM), maximum displacement value, intervertebral disc stress, maximum stress value, and articular protrusion stress, and by combining them with finite element stress cloud. Results: In normal and osteoporotic spines, there was no meaningful change in ROM or disc stress in the 2 surgical models for the 6 motion states. Model N1 (osteoporotic percutaneous transforaminal endoscopic discectomy model) showed a decrease in maximum displacement value of 20.28% in right lateral bending. Model M2 (unilateral biportal endoscopic model) increased maximum displacement values of 16.88% and 17.82% during left and right lateral bending, respectively. The maximum stress value of L4–5 increased by 11.72% for model M2 during left rotation. In addition, using the same surgical approach, ROM, maximum displacement values, disc stress, and maximum stress values were more significant in the osteoporotic model than in the normal model. Conclusion In both normal and osteoporotic spines, both surgical approaches were less disruptive to the physiologic structure of the spine. Furthermore, using the same endoscopic spine surgery, normal spine biomechanical properties are superior to osteoporotic spines.

Objective:To investigate the morphological and ultrastructural differences between normal and round-headed sperm and the outcomes of assisted reproduction in patients with partial globozoospermia.Methods:We collected clinical information and semen samples from 6 cases of partial globozoospermia confirmed in our hosptials from March 2023 to March 2024,performed Diff-Quik staining of the samples,observed the sperm morphology under the light microscope and transmission electron microscope,compared the ultrastructures between round-headed and normal spermatozoa,and analyzed the clinical outcomes of assisted reproduction in the pa-tients.Results:Under the light microscope,the the round-headed sperm had no acrosomal structure,some with tail abnormalities;while under the transmission electron microscope,they exhibited dissolved plasma membrane,acrosomal absence,small acrosomes,nucleoplasmic granulation,huge central vacuoles,swelling,absence or irregular arrangement of mitochondria in the neck,and disor-ganized or missed 9+2 microtubules in the tail.All the 6 patients underwent intracytoplasmic sperm injection(ICSI),and 1 of them achieved pregnancy.Conclusion:The sperm organelle is morphologically damaged and ultrastructurally abnormal in some patients with partial globozoospermia,which may be a key factor for their infertility,and ICSI can help some of them to achieve fertility.
