1.Research Advances in the Association Between Inflammation and Amyloid Toxicity in Alzheimer’s Disease
Journal of Sun Yat-sen University(Medical Sciences) 2025;46(6):973-984
Amyloid-β peptide (Aβ) is considered a major cause of Alzheimer's disease (AD). However, current researches emphasize that Aβ can activate microglia and astrocytes, which causes neuroinflammation. Neuroinflammation plays a crucial role in the neuronal mortality process, and can be considered the underlying cause of AD. In addition, vascular damage was proposed to play an important role in the pathogenesis of AD more than two decades ago, but few researchers have focused on the positive role of cerebrovascular damage in AD. In recent years, a growing body of evidence has supported that brain microvascular injury causes the occurrence of AD. Moreover, recent research indicated that inflammation caused by brain microvascular injury is also a significant risk factor for the development of AD. In damaged microvessels, C-reactive protein (CRP) is a non-specific inflammatory marker, which can activate the complement and enhance phagocytosis of immune cells, and help to eliminate pathogenic microorganisms from the body. The plenty of evidence indicated that CRP penetrated brain tissue and participated in neuroinflammation during brain microvascular injury, thereby influencing the pathogenesis of AD. Therefore, the negative effects of CRP and Aβ on the pathogenesis of AD are equally important. At present, few researchers have established a link between the effects of CRP and Aβ on AD and conducted in-depth analysis. This article firstly and deeply analyzed and summarized the significant function and connection of Aβ and CRP in AD, which provided support for the theory that neuronal cerebrovascular injury is the cause of AD.

Objective:To explore the therapeutic mechanism of electroacupuncture(EA)in treating Parkinson disease(PD)using Tandem mass tag(TMT)quantitative proteomics technology. Methods:Forty-eight PD patients were randomly divided into a control group and an observation group,with 24 patients in each group.The control group received routine drug treatment,while the observation group received EA in addition to the routine drug treatment.EA was administered for 30 min per session,3 times a week,for a total of 12 weeks.Nine patients from each group were randomly selected to provide peripheral blood serum samples before and after treatment for TMT quantitative proteomics analysis.Differentially expressed proteins between the two groups were compared,and bioinformatics analysis was performed.The screened differentially expressed proteins were validated using enzyme-linked immunosorbent assay(ELISA). Results:In the observation group,scores on the unified Parkinson disease rating scale(UPDRS),UPDRS Ⅱ,and UPDRS Ⅲ were significantly reduced after treatment(P<0.05).In the control group,these scores tended to increase,but the changes were not statistically significant(P>0.05).After treatment,the UPDRS and UPDRS Ⅲ scores in the observation group were significantly lower than those in the control group(P<0.05).The observation group showed 62 differentially expressed proteins,while the control group had 36.Compared to the control group,the observation group had 142 differentially expressed proteins.These proteins were primarily involved in the cyclic adenosine monophosphate(cAMP)signaling pathway,T helper(Th)1 and Th2 cell differentiation,ATP-binding cassette transporter,vascular endothelial growth factor signaling pathway,and high-affinity immunoglobulin E receptor(FcεRI)signaling pathway.ELISA verification indicated that after EA treatment,the levels of α-Synuclein(αSyn)and heat shock protein beta 1(HSPB1)in the observation group were significantly lower than those in the control group(P<0.05),while the regulator of G-protein signaling 10(RGS10)level was significantly higher(P<0.05). Conclusion:EA,combined with routine drug therapy,can significantly improve clinical symptoms of PD,potentially through the regulation of the cAMP signaling pathway and the contents of differentially expressed proteins of αSyn,HSPB1,and RGS10.

Objective To explore the association between green space and the risk of dyslipidemia. Methods “Dyslipidemia” and “ Normalized Difference Vegetation Index (NDVI)” were used as search terms to search PubMed, Embase, and Web of Science databases for studies up to September 2023. ARHQ statistical assessment and review tool and NOS scale were employed to evaluate the quality of the studies. R 4.3.1 software was used for meta-analysis. Results A total of 11 studies were included, of which 5 cross-sectional studies and 5 cohort studies were rated as “high quality”. The results of meta-analysis showed that an increase in NDVI in some buffer zones was associated with reduced risks of hypercholesterolemia, hypertriglyceridemia, low HDL-C, and high LDL-C, while an increase in NDVI in 100m buffer zone was significantly associated with reduced risks of all these four diseases, with hypercholesterolemia (OR=0.87, P<0.05), hypertriglyceridemia (OR=0.94, P<0.05), low HDL-C (OR=0.95, P<0.05), and high LDL-C (OR=0.87, P<0.05). Sensitivity analysis suggested that the results of most meta-analyses were robust. Conclusion With the increase in green space near residential areas, the risk of dyslipidemia may decrease.

Objective:To review the clinical status based on the best evidence of drug administration in patients with dysphagia, systematically analyze the obstacle factors and promoting factors in the process of evidence transformation, and formulate reform strategies.Methods:Based on the evidence-based nursing research method and the guidance of the Ottawa Model of Research Use (OMRU), the review indicators were developed based on the best evidence. The current status of clinical practice behaviors of 223 patients and 75 nurses in the Neurology, Neurosurgery and Geriatric departments of the Affiliated Hospital of Jiangsu University were reviewed from July to December 2021.Based on the results of the review, qualitative interviews were conducted with 32 potential adopters, and content analysis was used to assess the barriers and contributing factors to the clinical translation of evidence in three aspects: evidence-based change, potential adopters and practice environment, so as to develop effective strategies.Results:Based on the 22 best evidence selected, the evidence-based team developed 25 review indicators to carry out clinical review, showing that the compliance rate of 16 indicators were less than 60%. By analyzing and summarizing the interview results of potential adopters, the main obstacles leading to the low compliance rate of nurses were analyzed as follows: evidence-based reform changed the traditional work mode, and the application of evidence was not convenient; at the level of potential adopters, nurses had poor knowledge and practice, heavy work burden, and low awareness of patients and caregivers; at the level of practice environment, there was lack of nursing norms and procedures for clinical transformation of evidence, and the channels of multi-disciplinary collaboration and communication were not smooth. The main promoting factors were the perfect supervision mechanism of evidence-based nursing projects, the evidence-based group had rich experience in evidence transformation, the management was willing to change, and the practitioners were good at innovation.Conclusions:There is still a large gap between the clinical practice and the best evidence of drug administration in patients with dysphagia. The promoting factors should be fully utilized to overcome the obstacles and implement improvements to promote the effective transformation of evidence into clinical practice.
