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 observe the clinical effect of hysteroscopic combined with laparoscopic repair and reconstruction of diverticulum in the treatment of post-cesarean section uterine diverticulum(PCSD).Methods A total of 150 patients with PCSD admitted to the department of gynaecology of our hospital from January 2020 to February 2022 were selected and divided into the transvaginal group(transvaginal repair of diverticulum)and the combined group(hysteroscopic combined with laparoscopic repair and reconstruction of diverticulum)according to different surgical plans,with 75 cases in each group.The general condition of surgery,days of menstrual period,thickness of muscular layer,inflammation-related factor levels,complications and pregnancy in patients with birth plan were recorded in both groups.Results The operation time of patients in the combined group was longer than that in the transvaginal group,and the time of anal exhaustion and postoperative hospital stay of patients in the combined group were shorter than those in the transvaginal group,the differences were statistically significant(P<0.05);There was no significant difference in terms of the intraoperative bleeding volume of patients between the two groups(P>0.05).The high-sensitivity C-reactive protein(hs-CRP),interleukin-4(IL-4),interleukin-8(IL-8),and tumor necrosis factor-α(TNF-α)7 days after surgery of patients were lower in both groups compared with those before surgery,and the combined group was lower than the transvaginal group,the differences were statistically significant(P<0.05).Compared with that before the surgery,the days of menstrual period of patietns in both groups 6 and 12 months after the surgery decreased,and the thickness of muscular layer increased,with statistically significant differences(P<0.05);while no statistically significant difference was found in terms of the days of menstrual period or thickness of muscular layer of patients 6 and 12 months after surgery between the two groups(P>0.05).There was no significant difference in the incidence of cumulative complications such as incision infection,hyponatraemia,bladder injury and vaginal infection between the two groups(P>0.05).The intrauterine pregnancy rate of patients with birth plan and the full-term pregnancy rate in the combined group were higher than those in the transvaginal group,the differences were statistically significant(P<0.05).There was no statistically significant difference in the abortion rate or preterm birth rate between the two groups(P>0.05).Conclusion The hysteroscopic combined with laparoscopic repair and reconstruction of diverticulum for patients with PCSD has a fast postoperative recovery,a short hospital stay,and can increase the pregnancy rate of patients with birth plan.

Objective:To investigate the role of iron death in paraquat (PQ) -induced alveolar epithelial mesangialization (EMT) .Methods:In August 2023, the appropriate PQ staining concentration as well as the intervention concentration of lipoinhibitor-1 (Lip-1) were screened by CCK8 method. The RLE-6TN cells were divided into three groups, which were control group, PQ group and iron death inhibition group, 200 μmol/L PQ solution was given to the PQ group, and PQ 200 μmol/L and 0.1 μmol/L Lip-1 solution was given to the iron death inhibition group, the control group was added the same amount of cell medium. morphological changes and migratory viability of the cells in each group were observed at 12 h, 24 h and 48 h after the poisoning, and the contents of ferrous ions (Fe 2+), reactive oxygen radicals (ROS), glutathione (GSH), superoxide dismutase (SOD), and malondialdehyde (MDA) were detected in each group; meanwhile, qRT-PCR and western-blot were used to determine the molecular expression of E-cadherin, α-smooth muscle actin (α-SMA), and Collagen I in the cells in each group. The difference between group was compared by ANOVA, and the further pairwise comparison was conducted by Bonferroni method. Results:Cell viability was detected using CCK8, and the results showed that the cell survival rate of RLE-6TN cells treated with 200 μmol/L PQ+0.1 μmol/L Lip-1 solution was 56.6%. The migration activity of RLE-6TN cells in the iron death inhibition group was weaker than that in the PQ group after 24 and 48 hours of exposure, and the degree of EMT changes in the cells was reduced compared to the PQ group. After 12, 24, and 48 hours of exposure, the Fe 2+ concentration, ROS fluorescence intensity, and MDA content in the iron death inhibition group decreased compared to the corresponding time points in the PQ group ( P<0.05/3), while compared with PQ group, the GSH concentration and SOD concentration increased compared to the corresponding time points in the PQ group ( P<0.05/3). The results showed that compared with the control group, the expression levels of E-cadherin mRNA and protein in PQ group and iron death inhibition group were both decreased ( P<0.05/3), while compared with PQ group, the expression levels of E-cadherin mRNA and protein in iron death inhibition group were increased ( P<0.05/3) ; Compared with the control group, the expression levels of α-SMA, Collagen I mRNA and protein in PQ group and iron death inhibition group cells increased ( P<0.05/3), while compared with PQ group, the expression levels of α-SMA, Collagen I mRNA and protein in iron death inhibition group cells decreased ( P<0.05/3) . Conclusion:Ferroptosis is involved in the EMT process of alveolar epithelial cells induced by PQ. Inhibiting ferroptosis can reduce cellular oxidative damage and alleviate the degree of cellular EMT.

This study was aimed at analyzing the biotypes and genetic diversity characteristics of five non-major Brucella species,to provide a scientific basis for understanding the species diversity of Brucella and strengthening pathogen monitoring and control.According to the biotypes(species,hosts,isolation locations,and time)and MLVA-16 genotypes(MLVA-16 lo-cus data,MLVA-11 genotypes)of five non-major pathogenic Brucella in the international MLVA database,we used Bionu-merics 8.0 software and PHYLOVIZ2.0 online software to analyze the geographical origin and genetic diversity characteristics of strains.A total of 227 strains were studied,including 121 Brucella ceti,47 B.pinnipedialis,37 Brucella ovis,11 B.mi-croti,and Brucella neotomae.The greatest host diversity was observed for B.ceti,followed by B.pinnipedialis and B.mi-croti.B.ceti was distributed in European and South American countries;B.pinnipedialiswas distributed in Europe;and B.microti.was distributed in the Czech Republic,Austria,and Hungary in Central Europe.B.ovis was widely distributed in Af-rica,Argentina,Australia,Brazil,Greece,the United States,Spain,and France.The MLVA-11 genotypes of different types of Brucella showed high polymorphism and large differences,thus suggesting that the strains have different geographical ori-gins.MST analysis indicated that the studied strains were divided into four branches(BCⅠ-Ⅳ),among which B.ceti was di-vided into two different branches(BC-Ⅰ and BC-Ⅱ),the strains of other types formed different branches(or sub-branches),and the strains of different types showed clear regional and dominant host characteristics.Genetic correlation analysis of strains of the Brucella genus revealed that non-major pathogenic Brucella had clear genetic,distribution,and host spectrum differ-ences with respect to four classical pathogenic Brucella species.Five non-major pathogenic Brucella strains presented unique genetic evolutionary patterns,geographical distributions,and host tropism characteristics,thereby providing new insight for understanding the biological and genetic diversity of those Brucella strains.

This study was aimed at investigating the effects of demethylase fat mass and obesity-associated protein(FTO)and methyltransferase methyltransferase like protein 3(METTL3),key molecules in N6-methyladenosine(m6A)modification,on the replication and proliferation of Japanese encephalitis virus(JEV).Recombinant lentiviruses were generated by packaging the FTO and green fluorescent protein into lentiviral vectors.Neuro2a cells,a mouse neuroblastoma cell line,were infected with the lentivirus,and stable FTO-expressing cell lines were obtained through puromycin selection.Successful overexpression of FTO was confirmed through fluorescence microscopy,real-time quantitative PCR,and western blot analysis.When Neuro2a cells overexpressing FTO were infected with JEV,the overexpression of FTO decreased JEV replication in the cells,and increased the expression of interferon(IFN)and related molecules.Additionally,treatment of JEV-infected Neuro2a cells with the METTL3-specific inhibitor STM2457 resulted in a dose-dependent decrease in JEV replication and viral protein expression.These findings suggested that lowering m6A methylation levels inhibits JEV replication,thus shedding light on the regulatory role of methylation modification in JEV replication.

To explore the understanding of the target population regarding the Get Active Questionnaire for Pregnancy(GAQ-P)and the Companion Health Care Provider Consultation Form for Prenatal Physical Activity(cHCP-CF-PPA)in the Chinese context,and to verify the consistency of the Chinese version of the prenatal physical activity dual screening questionnaire with the original version in terms of language expression,27 pregnant women and 12 healthcare providers were selected from Obstetrics and Gynecology Hospital,Fudan University during Aug and Oct 2023,and were interviewed using purposive sampling.Two rounds of cognitive interviews were conducted.The first round revealed that some respondents experienced ambiguities in understanding the meanings of 5 items in the questionnaire.Following modifications,the second round indicated that the revised items were consistent in meaning with the original questionnaire.Cognitive interviews can facilitate the adaptation of the prenatal physical activity dual screening questionnaire to the Chinese cultural context,improve the understanding of the questionnaire items among the target population,and promote the localization of the screening tool.

The molecular mechanisms underlying the develop-ment and metastasis of prostate cancer remain elusive.This comprehensive review delves into the intricate role of cofilin,an actin-binding protein,in the pathogenesis and progression of prostate cancer.Cofilin is a significant protein in cytoskeletal dynamics,and any dysregulation may result in the morphological changes in normal cells and the invasion and metastasis of tumor cells.Research has revealed that the activity of cofilin is regula-ted by various mechanisms,including phosphorylation/dephos-phorylation and interactions with other molecules.Moreover,this review discusses promising therapeutic interventions,such as co-filin inhibitors and gene therapy,which have demonstrated effica-cy in preclinical models.The challenge of clinically preventing the transition to castration-resistant prostate cancer and tumor metastasis is widely recognized,necessitating the development of precise drug treatments and biomarker identification.As a key regulatory protein,cofilin provides a more comprehensive refer-ence for the prevention and treatment of prostate diseases.

Objective To evaluate the effect of Intravascular lithotripsy(IVL)in the treatment of calcified nodules,and to observe the presence of coronary dissection after IVL treatment.Methods A total of 106 patients with coronary atherosclerotic heart disease(coronary heart disease)admitted to the cardiovascular Department of Shougang Hospital,Peking University from March 2023 to July 2024 were retrospectively analyzed.A total of 106 patients with moderate to severe stenosis accompanied by calcification as detected by coronary angiography were treated with IVL after intravascular ultrasound(IVUS)examination.Patients were divided into two groups according to whether there were calcified nodules in the coronary lesions:39 cases in the calcified nodules group and 67 cases in the non-calcified nodules group.The occurrence of coronary dissection during surgery was observed between the two groups,and other perioperative related complications and major adverse cardiovascular events(MACE)within 1 month after percutaneous coronary intervention(PCI)were compared between the two groups.Results The levels of renal insufficiency(25.6％vs.9.0％,P=0.021)and creatinine[(119.71±134.75)μmol/L vs.(71.82±16.53)μmol/L,P=0.033]in the calcified nodule group were higher than those in the non-calcified nodule group,the difference was statistically significant,and there was no difference in other baseline data.The target vessels in the calcified nodule group were mainly left anterior descending branch and right coronary artery,while those in the non-calcified nodule group were mainly left anterior descending branch,with few circumflex branches in both groups,and there was statistical significance in the distribution of target vessels in the left anterior descending branch and right coronary artery between the two groups(P=0.020).In terms of eccentric calcification(P=0.048)and asymmetric calcification(48.7％vs.28.4％,P=0.035)between the two groups,the calcified nodule group was higher than the non-calcified nodule group,the difference was statistically significant(P＜0.05).In terms of whether more than 20 pulses were needed and whether there was slippage during IVL,the calcified nodule group was higher than the non-calcified nodule group,the difference was statistically significant(P=0.022).The success rate of interventional therapy was 100％in both groups.After IVL treatment,the calcified nodule group was higher than the non-calcified nodule group in terms of the occurrence of coronary artery dissection,the difference was statistically significant(P＜0.009).The MACE of the two groups within 1 month after PCI was slightly higher in the calcified nodule group than in the non-calcified nodule group,but the difference was not statistically significant(P=0.235).Conclusions IVL is feasible and effective for the treatment of calcified coronary nodules.However,in the course of treatment,the occurrence of coronary dissection should be vigilant,identified as early as possible,and treated in time.
