Stress is a critical inducer in the onset and progression of many chronic diseases. Prolonged or intense stress can disrupt the overall balance between the nervous, immune, and endocrine systems. The resulting biological signals may act on corresponding receptors in the cervical spine region, leading to adverse pathological changes. The vertebral artery and the surrounding muscular and connective tissues are influenced by biomechanical abnormalities and inflammatory cascades associated with cervical spondylosis of vertebral artery type (CSA), which promotes the release of various hormones. These hormones, through the neuroendocrine-immune system, affect the central nervous system, inducing or exacerbating negative emotional feedback and thereby establishing a "central-local-central" vicious cycle. This article explores the mechanisms underlying the impact of stress on the key CSA symptoms through the neuroendocrine-immune network (NEI) theory, providing a more comprehensive framework for targeted therapeutic interventions in CSA.

In recent years, the incidence rate of pertussis in China has been steadily increasing, presenting an increasingly severe challenge for disease prevention and control. To strengthen the immune barrier in the population and effectively curb the spread of pertussis, National Disease Control and Prevention Administration of China and other relevant authorities optimized the immunization procedure for diphtheria-tetanus-pertussis vaccine, with the new procedure implemented in 2025. This adjustment includes three key measures: advancing the initial dose of the vaccine from 3 months to 2 months of age, extending the interval between primary immunization doses from 1 month to 2 months, and adding an extra dose of acellular diphtheria-tetanus-pertussis vaccine at 6 years of age. This article discusses potential changes in the epidemiology and clinical manifestations of pertussis following such adjustments for immunization procedure, and awareness of these changes will facilitate the accurate identification of pertussis cases, which is crucial for evaluating the impact of these adjustments and further optimizing immunization strategies.

OBJECTIVES: To study the clinical characteristics of rashes induced by trimethoprim-sulfamethoxazole (TMP-SMZ) in children treated for pertussis and to inform safe medication practices. METHODS: A retrospective analysis was conducted on 238 children diagnosed with pertussis and treated with TMP-SMZ at Wuhu First People's Hospital from January to August 2024. The incidence and clinical features of rashes were summarized. RESULTS: Of 238 children, 34 (14.3%) developed rashes; 19 (55.9%) were boys, and the 5 to <10-year age group accounted for the highest proportion (70.6%, 24/34). A history of allergic disease was present in 50.0% (17/34). Rashes typically appeared on or after day 7 of therapy (82%, 28/34) and were predominantly erythematous or maculopapular eruptions (97%, 33/34); 71% (24/34) were pruritic. Fever occurred in 56% (19/34); among those who were tested for respiratory viruses, 77% (10/13) were positive for viruses such as rhinovirus and adenovirus. After discontinuation of TMP-SMZ, rashes resolved within 3 days in 97% (33/34) of patients (41% within 1 day; 56% within more than 1 but within 3 days). There was no significant difference in rash incidence between photoprotection and non-photoprotection groups (P>0.05). CONCLUSIONS TMP-SMZ for pertussis can induce rashes, particularly in children aged 5 to <10 years. The eruption is usually a pruritic erythematous or maculopapular rash, with over half of cases accompanied by fever and frequent concomitant viral infections. Most rashes resolve within 3 days after drug withdrawal. The potential association between the rash and sun exposure warrants further investigation.

Alzheimer's disease(AD), a neurodegenerative disorder associated with aging, is the most prevalent form of dementia.As the aging population continues to expand, AD presents significant health and caregiving challenges for families and society, making it a pressing international public health concern.In recent years, numerous countries have implemented dementia prevention and treatment strategies that emphasize community-based comprehensive approaches.Currently, the community-based AD prevention and treatment model in China is still in the exploratory phase, with community efforts lacking organization.In alignment with China's action plan for advancing dementia prevention and treatment, and to achieve the strategic objective of "healthy aging, " this consensus is based on the principle of three-level prevention and is tailored to the characteristics of AD disease progression.It aims to develop a comprehensive prevention and treatment strategy for AD that is suitable for communities in China, providing technical guidance and support to establish a scientific basis for formulating community AD prevention and treatment models.

Objective:To evaluate the protective effectiveness (VE) of the acellular pertussis vaccine (aPV) against pertussis in children aged 2 months to 6 years.Methods:A test-negative case-control study was conducted among children aged 2 months to 6 years who sought medical care for cough and underwent pertussis nucleic acid testing at sentinel surveillance hospitals in Zhejiang Province in 2024. Cases were defined as those with positive pertussis nucleic acid test results, while controls were test-negative individuals matched 1∶1 based on propensity scores using the caliper matching method. Conditional logistic regression models were used to calculate odds ratios ( ORs) and VEs. Results:Among the 658 participants, 31.76% (209 cases) tested positive for pertussis. After propensity score matching, 203 cases and 203 controls were included in the analysis. The VE of 1-2, 3, and 4 doses of aPV against pertussis was 52.46% (95% CI:-39.82%-83.84%), 65.22% (95% CI: 6.86%-87.02%), and 72.21% (95% CI: 34.33%-88.24%), respectively. For pertussis-related hospitalization, the VE of 1-3 and 4 doses was 80.95% (95% CI:31.38%-94.71%) and 86.79% (95% CI: 51.89%-96.37%). The VE for those who completed 4 doses of vaccination and had intervals of less than 2 years, 2 years, 3 years, and 4 years or more after vaccination were 91.15% (95% CI: 67.61%-97.58%), 84.70% (95% CI: 43.71%-95.84%),56.23% (95% CI:-47.58%-87.02%), and 49.92% (95% CI:-83.74%-86.35%), respectively. Conclusion:The VE of aPV against pertussis in children aged 2 months to 6 years increases with the number of doses administered, and it is more effective in preventing hospitalization due to pertussis. The VE declines rapidly over time after the last dose. It is recommended to follow the new pertussis immunization program for timely and full vaccination.

Objective To investigate the underlying mechanism of Hongyu Decoction in the treatment of inflammatory bowel disease(IBD)based on serum amino acid metabolism.Methods A total of 50 male C57BL/6J mice were divided into control group,model group,sulfasalazine(SASP)group and Hongyu Decoction low-and high-dosage groups,with 10 mice in each group.Except for the control group,the rest groups were treated with 3%dextran sulfate sodium freely for seven consecutive days to establish the IBD model.The SASP group was given SASP solution at a dosage of 200 mg/kg by gavage,while the Hongyu Decoction low-and high-dosage groups were given Hongyu Decoction freeze-dried powder solution at dosages of 0.5 and 2.0 g/kg respectively by gavage for 11 consecutive days.The general condition was monitored and DAI score were calculated.After the mice were sacrificed,the length of colons was measured,ELISA was used to detect serum TNF-α,IL-1β,IL-17 contents,HE staining was used to observe the morphology of colon tissue,and Alizarin blue staining was used to evaluate the secretion of mucin levels by intestinal epithelial goblet cells,UPLC-MS and multivariate statistical methods were used to analyze the serum amino acid metabolism profiles of mice in the control group,model group and Hongyu Decoction high-dosage group,and differential amino acids were screened.Pathway enrichment analysis was performed on differential amino acids using MetaboAnalyst 5.0.Results Compared with the control group,the DAI score of the model group mice significantly increased(P<0.001),the colon length was significantly shortened(P<0.001),and the serum contents of TNF-α,IL-1β and IL-17 significantly increased(P<0.001);with widespread ulceration of colon tissue,disappearance of mucosal epithelium and intestinal crypt structure,infiltration of lymphocytes and neutrophils,congestion and edema of intestinal mucosa,proliferation of submucosal connective tissue,reduced number of colonic goblet cells and mucin secretion.Compared with the model group,the Hongyu Decoction high-dosage group showed a significant decrease in DAI score(P<0.001),while the SASP group and the Hongyu Decoction low-and high-dosage groups showed a significant increase in colon length(P<0.05,P<0.001),and the serum contents of TNF-α,IL-1β and IL-17 were significantly reduced(P<0.001);the colonic villi were relatively intact,the glands were clear and arranged neatly,the branches of the intestinal crypts were obvious,no obvious edema was observed,and the number of colonic goblet cells and mucin secretion increased.Seven potential biomarkers for IBD in mice were identified through serum metabolomics screening,including tryptophan,serine,glutamate,valine,histidine,methionine and phenylalanine;two potential biomarkers for the treatment of IBD with Hongyu Decoction were identified,namely valine and tyrosine.The results of pathway enrichment analysis showed that the differential amino acids in the model group mainly involved the biosynthesis of phenylalanine,tyrosine and tryptophan,histidine metabolism,cysteine and methionine metabolism,phenylalanine metabolism and arginine biosynthesis;the differential amino acids in Hongyu Decoction high-dosage group mainly involved the biosynthesis of phenylalanine,tyrosine and tryptophan,as well as the metabolism of alanine,aspartate and glutamate,and the biosynthesis of arginine.Conclusion Hongyu Decoction can improve intestinal epithelial damage and inflammatory cell infiltration in IBD mice,protect the integrity of the intestinal mucosal barrier,and may be related to regulating amino acid metabolism in the body.
