In recent years,significant breakthroughs have been achieved in the immunotherapy for Alzheimer's disease.In line with global advancements,two anti-amyloid-β monoclonal antibodies have been approved and successfully launched in China for clinical use.Lecanemab and Donanemab were officially used in June 2024 and April 2025 in China,respectively.In order to standardize the rational and safe application of anti-amyloid-β monoclonal antibodies for Alzheimer's disease in China,this article integrates recom-mendations from the clinical trials and real-world experience from the author's team and domestic peers to further update the recom-mendations for the clinical use of anti-amyloid-β monoclonal antibody based on the 2024 version.It includes indications for therapy,pre-treatment evaluation and preparation,administration protocols and safety measures during treatment,and post-treatment monitor-ing strategies.

G protein-coupled receptor 120(GPR120)is one of the membrane receptors for long chain free fatty acids and is distributed in alveolus macrophages and airway epithelial Club cells.GPR120 activation alleviates the inflammation of respiratory tract,improves airway hyper-responsiveness,stimulates proliferation of Club cells and promotes the repair of respiratory epithelium,which may attenuate asthma and acute lung injury.

Objective To investigate the correlation of plasma homocysteine(Hcy)level and the polymorphisms of its key metabolic enzymes methylenetetrahy-drofolate reductase(MTHFR)gene with ischemic stroke(IS).Methods A total of 310 patients with IS were enrolled as the case group and 330 healthy subjects during the same period were selected as the control group.Plasma Hcy concentration was detected by enzyme cycling method,and the real-time fluorescent quantitative PCR(RT-qPCR)was used to detecte the genotypes of MTHFR C677T.Results The frequencies of TT genotype(36.13%),CT genotype(10.00%)and T allele(28.06%)of MTHFR gene C677T locus in stroke patients were significantly higher than that in control group(P＜0.05).The frequency of the TT genotype was significantly higher in IS group compared to control group,indicating a recessive mode of inheritance(P＜0.05);In the dominant mode of inheritance,the frequency of CT+TT genotype in IS group was also significantly higher than that in control group(P＜0.05);The plasma Hay concentration of MTHFR C677T genotype TT,CT and CC patients was statistically different(P＜0.05),which were(20.91±6.78)μmol/L(17.20±5.39)μmol/L,(14.35±4.32)μmol/L,respectively;The area under the ROC curve(AUC)of plas-ma total Hcy level was 0.610(95%CI:0.566～0.653,P＜0.001).It indicated that it might play an impor-tant role in predicting the risk of suffering from IS.Multivariate Logistic regression analysis showed that plasma Hcy level and MTHFR C677T gene polymorphism were important risk factors of IS.Conclusions Elevated plasma Hcy level is associated with IS,and the synergistic effect of elevated Hcy level and MTHFR C677T gene mutation may increase the risk of IS.

Objective To investigate the relationship between methylenetetra-hydrofolatereductase(MTHFR)gene polymorphism and serum homocysteine(Hcy)level and subtypes of ischemic stroke(IS).Methods The study was conducted according to the matched principle of case-control design,310 patients with IS and 330 healthy people during the same period were selected as the case group and the control group.Recycling enzyme method and the real-time fluorescent quantitative PCR(RT-qPCR)method were used to detect the level of serum Hcy and the genotypes of MTHFR C677T,respectively.Results There was a significantly difference in MTHFR C677T genotype and allele frequency between the case and control groups(P＜0.05).The correlation analysis with different subtypes indicated that the frequencies of CT genotype(38.02%),TT genotype(10.74%),and T allele(29.75%)were significantly different in the LAA group(OR=1.662,95%CI:1.058-2.608,P＜0.05;OR=2.373,95%CI:1.110-5.073,P＜0.05;OR=1.663,95%CI:1.190-2.323,P＜0.05);The frequencies of TT genotype(10.53%)and T allele(27.30%)in SAO group were also significantly different(OR=2.130,95%CI:1.046-4.336,P＜0.05;OR=1.474,95%CI:1.075-2.021,P＜0.05).Further analysis of serum Hcy level showed that LAA group(19.55±5.61)μmol/L and SAO group(16.37±5.20)μmol/L were significantly higher than the control group(14.46±4.61)μmol/L(P＜0.001);Among the patients of both subtypes the serum Hcy levels in those with CT genotypes and TT genotypes were significantly higher than those in patients of CC genotypes(P＜0.001).Conclusions The gene polymorphism of MTHFR C677T has a significant effect on Hcy level in pa-tients with LAA and SAO stroke.

Following the principles of evidence-based medicine,in accordance with the structure and drafting rules of standardized documents,based on literature research,according to the characteristics of chronic cough in children and issues that need to form a consensus,the TCM Guidelines for Diagnosis and Treatment of Chronic Cough in Children was formulated based on the Delphi method,expert discussion meetings,and public solicitation of opinions.The guideline includes scope of application,terms and definitions,eti-ology and diagnosis,auxiliary examination,treatment,prevention and care.The aim is to clarify the optimal treatment plan of Chinese medicine in the diagnosis and treatment of this disease,and to provide guidance for improving the clinical diagnosis and treatment of chronic cough in children with Chinese medicine.

Diabetic peripheral neuropathy(DPN)is a common and devastating complication of diabetes,for which effective therapies are currently lacking.Disturbed energy status plays a crucial role in DPN pathogenesis.However,the integrated profile of energy metabolism,especially the central carbohy-drate metabolism,remains unclear in DPN.Here,we developed a metabolomics approach by targeting 56 metabolites using high-performance ion chromatography-tandem mass spectrometry(HPIC-MS/MS)to illustrate the integrative characteristics of central carbohydrate metabolism in patients with DPN and streptozotocin-induced DPN rats.Furthermore,JinMaiTong(JMT),a traditional Chinese medicine(TCM)formula,was found to be effective for DPN,improving the peripheral neurological function and alleviating the neuropathology of DPN rats even after demyelination and axonal degeneration.JMT ameliorated DPN by regulating the aberrant energy balance and mitochondrial functions,including excessive glycolysis restoration,tricarboxylic acid cycle improvement,and increased adenosine triphosphate(ATP)generation.Bioenergetic profile was aberrant in cultured rat Schwann cells under high-glucose conditions,which was remarkably corrected by JMT treatment.In-vivo and in-vitro studies revealed that these effects of JMT were mainly attributed to the activation of adenosine monophosphate(AMP)-activated protein kinase(AMPK)and downstream peroxisome proliferator-activated receptor gamma coactivator 1-alpha(PGC-1α).Our results expand the thera-peutic framework for DPN and suggest the integrative modulation of energy metabolism using TCMs,such as JMT,as an effective strategy for its treatment.
