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.

In order to further standardize the vaccination of kidney transplant candidates and recipients in China, the Branch of Organ Transplantation of Chinese Medical Association has organized experts in kidney transplantation and infectious diseases. Based on the "Vaccination of Solid Organ Transplant Candidates and Recipients: Guidelines from the American Society of Transplantation Infectious Diseases Community of Practice", and in combination with the clinical reality of infectious diseases and vaccination after organ transplantation in China, as well as referring to relevant recommendations from home and abroad in recent years, these guidelines are formulated from aspects such as epidemiology, types of vaccines, vaccination principles, target population, and specific vaccine administration. The "Guidelines for Vaccination of Kidney Transplant Candidates and Recipients in China" aims to provide theoretical reference for medical workers in the field of kidney transplantation in China, regarding the vaccination of kidney transplant candidates and recipients. It is expected to better guide the vaccination of kidney transplant candidates and recipients, reduce the risk of postoperative infection, and improve survival outcomes.

Background: The association of changes in metabolic syndrome (MetS) with cognitive function remains unclear. We explored this association using prospective and Mendelian randomization (MR) studies. Methods: MetS components including high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), waist circumference (WC), fasting plasma glucose (FPG), and triglycerides were measured at baseline and two follow-ups, constructing a MetS index. Immediate, delayed memory recall, and cognitive function along with its dimensions were assessed by immediate 10- word recall test (IWRT) and delayed 10-word recall test (DWRT), and mini-mental state examination (MMSE), respectively, at baseline and follow-ups. Linear mixed-effect model was used. Additionally, the genome-wide association study (GWAS) of MetS was conducted and one-sample MR was performed to assess the causality between MetS and cognitive function. Results: Elevated MetS index was associated with decreasing annual change rates (decrease) in DWRT and MMSE scores, and with decreases in attention, calculation and recall dimensions. HDL-C was positively associated with an increase in DWRT scores, while SBP and FPG were negatively associated. HDL-C showed a positive association, whereas WC was negatively associated with increases in MMSE scores, including attention, calculation and recall dimensions. Interaction analysis indicated that the association of MetS index on cognitive decline was predominantly observed in low family income group. The GWAS of MetS identified some genetic variants. MR results showed a non-significant causality between MetS and decrease in DWRT, IWRT, nor MMSE scores. Conclusion Our study indicated a significant association of MetS and its components with declines in memory and cognitive function, especially in delayed memory recall.

ObjectiveTo investigate the effects of mitotically-associated long non-coding RNA （lncRNA MANCR） on the proliferation，migration， and epithelial mesenchymal transition （EMT） of gastric cancer （GC） cells by regulating the microRNA-50-5p （miR-150-5p）/non-metastatic melanoprotein B （GPNMB） axis. MethodsThe mRNA expressions of lncRNA MANCR，miR-150-5p， and GPNMB in 42 cases of GC tissue and adjacent tissue resected during surgery in the First Hospital of Hebei Medical University from June 2022 to September 2023 were detected by Real-time PCR. Human gastric mucosal epithelial cells GES-1 and human GC cells BGC-823 were cultured in vitro， and their lncRNA MANCR expression was detected. BGC-823 cells were randomly separated into control group （routine culture），sh-NC group （with sh-NC transfected），sh-MANCR group （with sh-MANCR transfected），sh-MANCR + anti-NC group （with sh-MANCR and anti-NC both transfected），and sh-MANCR + anti-miR-150-5p group （with sh-MANCR and anti-miR-150-5p both transfected）. The mRNA expressions of lncRNA MANCR，miR-150-5p， and GPNMB in the BGC-823 cells of all groups were analyzed. EdU staining was used to detect the proliferation of BGC-823 cells. Transwell assay was used to detect the migration and invasion of BGC-823 cells. The expressions of EMT-related proteins E-cadherin，N-cadherin，Vimentin， and GPNMB were detected by Western blot. The interactions between lncRNA MANCR and miR-150-5p and between miR-150-5p and GPNMB were analyzed by dual luciferase reporter assay. ResultsThe mRNA expressions of lncRNA MANCR and GPNMB in GC tissue were higher than those in adjacent tissue，and the expression of miR-150-5p was lower than that in adjacent tissue （P<0.05）. Compared with that in GES-1，lncRNA MANCR expression in BGC-823 cells was increased （P<0.05）. Compared with those in the sh-NC group and control group，the EdU-positive cell rate，migration number，invasion number，the mRNA expressions of lncRNA MANCR and GPNMB， and the expressions of protein，N-cadherin protein， and Vimentin protein in the BGC-823 cells in the sh-MANCR group were lower ，and the protein expressions of miR-150-5p and E-cadherin were higher （P<0.05）. Compared with those in the sh-MANCR group and the sh-MANCR + anti-NC group，the protein expressions of miR-150-5p and E-cadherin in the sh-MANCR + anti-miR-150-5p group were decreased. The EdU-positive cell rate，migration number，invasion number，mRNA expressions of GPNMB， and expressions of protein，N-cadherin protein， and Vimentin protein were increased （P<0.05）. lncRNA MANCR could target the negative regulation of miR-150-5p，and miR-150-5p could target the negative regulation of GPNMB. ConclusionKnockout of lncRNA MANCR can inhibit the proliferation，migration， and EMT of GC cells by regulating the miR-150-5p/GPNMB axis.
