Vascular aging (VA) is a common etiology of various chronic diseases and represents a major public health concern. Intermittent hypoxia (IH) associated with obstructive sleep apnea-hypopnea syndrome (OSAHS) is a primary pathological and physiological driver of OSAHS-induced systemic complications. A substantial proportion of OSAHS patients, estimated to be between 40% and 80%, have comorbidities such as hypertension, heart failure, coronary artery disease, pulmonary hypertension, atrial fibrillation, aneurysm, and stroke, all of which are closely associated with VA. This review examines the molecular and cellular features common to both OSAHS and VA, highlighting decreased melatonin secretion, impaired autophagy, increased apoptosis, increased inflammation and pyroptosis, increased oxidative stress, accelerated telomere shortening, accelerated stem cell depletion, metabolic disorders, imbalanced protein homeostasis, epigenetic alterations, and dysregulated neurohormonal signaling. The accumulation and combination of these features may underlie the pathophysiological link between OSAHS and VA, but the exact mechanisms by which OSAHS affects VA may require further investigation. Taken together, these findings suggest that OSAHS may serve as a novel risk factor for VA and related vascular disorders, and that targeting these features may offer therapeutic potential to mitigate the vascular risks associated with OSAHS.

Objective To explore the potential profile of body image and its influencing factors among head and neck cancer patients.Methods Convenience sampling was employed to investigate 335 head and neck cancer patients in a tertiary hospital in Shandong Province from October 2023 to May 2024.Data was collected using the patient's general information questionnaire,Body Image Scale,Medical Coping Modes Questionnaire,Perceived Social Support Scale,Comprehensive Score for Financial Toxicity based on the Patient-Reported Outcome Measures.Latent profile analysis and multivariate Logistic regression analysis were used to explore distinct profiles and influencing factor of body image in head and neck patients.Results A total of 335 valid questionnaires were collected in this study,and 95.4％of the valid questionnaires were included.Body image of patients with head and neck cancer could be divided into 3 latent profiles:body emotional stability(41.5％),body cognitive dissatisfaction(33.7％)and social behavior avoidance(24.8％).Age,location of cancer onset,stage of cancer,surgical treatment,medical coping style(facing coping,yielding coping),social support and economic toxicity were the factors influencing the latent profiles of body image in patients with head and neck cancer(P＜0.05).Conclusion There is heterogeneity in body image of patients with head and neck cancer.Medical staff should implement targeted management strategies based on the influencing factors of different profiles to reduce the body image disorders in patients with head and neck cancer,and to promote patients to better return to society.

Carbapenem-resistant Enterobacteriaceae(CRE), one of the most urgent pathogens threatening human health worldwide, has posed a great challenge to clinical treatment. However, the imbalance between the lag in antibiotic research and development and the increase of CRE resistance has led to a "death threat" for patients infected with CRE, and it is urgent to explore new mechanisms of CRE resistance, which is closely related to the role of resistance genes, carbapenemases and efflux pumps. In addition, penicillin-binding protein, biofilms and iron carriers are expected to provide new research ideas to understand the drug resistance mechanism. The aim of this review is to summarize the mechanisms of CRE resistance and to provide new ideas for its treatment.

Objective To study the mechanism by which acoustic wave stimulation improves cognitive function in sleep-deprived mice.Methods(1)Thirty-six male C57BL/6 mice were randomly divided into three groups:the control group,model group and acoustic wave group(n=12 per group).A sleep deprivation model was established using the modified multiple platform method.After 21 days of sleep deprivation in a row,mice in the acoustic wave group were exposed to 30-minute acoustic wave stimulation at 40 dB.(2)During sleep deprivation,the health status of each group of mice was recorded,including the mental state and body weight.(3)After 21 days of sleep deprivation,behavioral tests(open field test,novel object recognition test,Y-maze and Morris water maze)were performed to assess the spontaneous activity,spatial exploration,and such cognitive functions as learning and memory in mice.Immunohistochemistry was conducted to analyze the expressions of neuronal nuclear antigen(NeuN),glial fibrillary acidic protein(GFAP)and ionized calcium-binding adaptor molecule 1(Iba-1)in the hippocampus.Quantitative real-time PCR(qPCR)was used to measure the expression levels of interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-α)and inducible nitric oxide synthase(iNOS)in the hippocampus.(4)Transcriptome sequencing was employed to explore the mechanism underlying the improvement of cognitive impairment by acoustic wave stimulation.Results After 21 days of sleep deprivation,acoustic wave stimulation significantly alleviated weight loss in mice(P＜0.01).The accuracy of Y-maze spontaneous alternation,indexes of novel object discrimination,the time spent in the target quadrant and the number of times the mice crossed the platformin the Morris water maze were all significantly increased(P＜0.05),while the escape latency was significantly reduced(P＜0.05).The average optical density of NeuN in the hippocampal CA3 region significantly increased(P＜0.05),GFAP and Iba-1 immunopositive cell counts significantly decreased(P＜0.01),and the mRNA levels of IL-6,TNF-α,and iNOS in the hippocampal tissue were significantly reduced(P＜0.05).Conclusion Acoustic wave stimulation can repair neural damage,modulate hippocampal inflammatory responses,and improve cognitive deficits induced by sleep deprivation.

Objective To investigate the prevalence of scoliosis and congenital heart disease(CHD)and their correlation among children and adolescents of Drung nationality in Yunnan Province.Methods A cross-sectional survey was conducted in November 2022 among all Drung school-aged children and adolescents aged 5-18 years in Gongshan Drung and Nu Autonomous County,Yunnan Province.Visual inspection,Adams for-ward flexion test,and trunk rotation angle(ATR)measurement were comprehensively used for school prelim-inary screening of scoliosis.Individuals who tested positive in the school preliminary screening underwent fur-ther X-ray examination for auxiliary diagnosis.Cardiac auscultation and echocardiography were used for school preliminary screening of CHD.The personal information of the screening subjects,the screening results,etc.were recorded.The prevalence of scoliosis and CHD among children and adolescents of the Drung nationality and the relationship between the two diseases were statistically analyzed,and the positive predictive value of school-based scoliosis screening and its influencing factors were also analyzed.Results A total of 1 036 chil-dren and adolescents of Drung nationality were enrolled,with a mean age of(10.72±3.75)years,icluding 542 males and 494 females.A total of 45 subjects tested positive for scoliosis in the school preliminary screening,with a preliminary positive rate of 4.34%.A total of 22 cases were finally diagnosed with scoliosis,with a prevalence rate of 2.12%.Among them,21 cases were idiopathic scoliosis(accounting for 95.45%),and 1 case was congenital scoliosis(accounting for 4.55%).The prevalence rate was higher in females(2.83%)than that in males(1.48%),higher in the 10 to 18-year-old group(2.30%)than that in the 5 to<10-year-old group(1.87%),and higher in the secondary school group(2.78%)than that in the primary school group(1.78%),hut there were no statistically significant differences(P>0.05).Most idiopathic scoliosis cases were mild(Cobb angle 10° to<20°,90.48%)and classified as Lenke type Ⅴ(57.14%).Two cases of CHD were confirmed,both of which were atrial septal defects,with a prevalence rate of 0.19%.The co-occurrence rate of idiopathic scoliosis and CHD was 4.76%(1/21).The positive predictive value of school-based scoliosis pre-liminary screening was only 48.89%.When the BMI was<18.5 kg/m2,the positive predictive value was sig-nificantly higher than that for BMI≥18.5 kg/m2(P<0.05).Conclusion The prevalence rate of scoliosis a-mong adolescents of the Drung ethnic group in Yunnan Province is 2.12%,predominantly idiopathic scoliosis,with Lenke type V being the most common classification.The prevalence rate of congenital heart disease is 0.19%.BMI is a significant influencing factor for the positive predictive value of school-based scoliosis prelimi-nary screening.

Objective:To investigate the age-specific distribution characteristics of plantar pressure parameters in healthy children aged 3-12 years.Methods:This cross-sectional study retrieved data from the hospital information system in January 2025 for 272 children aged 3-12 years who underwent physical examinations and voluntarily completed plantar pressure analysis at Beijing Children′s Hospital, Capital Medical University, from July 2022 to December 2024. Demographic and clinical data, including anthropometric measurements (height and weight), flatfoot diagnosis and plantar pressure parameters (maximum pressure, time to maximum force, and contact time percentage in bilateral forefoot, midfoot, and hindfoot) were recorded. Participants were categorized into 3 age groups (3-6 years, 7-9 years, and 10-12 years) and were grouped by gender as well. Intergroup comparisons used one-way ANOVA or least-significant difference test or χ2 tests. Spearman′s rank correlation assessed the relationship between flatfoot prevalence and age. Results:Among 272 children (143 boys, 129 girls), age groups comprised 3-6 years (118 children, 64 boys and 54 girls), 7-9 years (96 children, 49 boys and 47 girls), and 10-12 years (58 children, 30 boys and 28 girls). Flatfoot prevalence was higher in boys than in that of girls (41.3% (59/143) vs. 28.7% (37/129), χ2=4.70, P=0.030), and negatively correlated with age ( r=-0.21, P<0.001). There all had statistically differences in the maximum pressure values of the bilateral forefoot and hindfoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all the lowest, and those of the group of aged 10-12 years were all the highest (all P<0.05). The maximum pressure values of bilateral midfoot in the group of aged 10-12 years were all higher than those of the other two groups (all P<0.001). There had no statistically differences in the time maximum force value of the bilateral forefoot among the 3 age groups (all P>0.05). The time maximum force values of bilateral midfoot in the group of aged 3-6 years were all lower than those of the other two groups (all P<0.05). There all had statistically differences in the time maximum force value of the bilateral hindfoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all the lowest, and those of the group of aged 10-12 years were all the highest (all P<0.05). There all had statistically differences in the contact time percentage values of the bilateral forefoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all the lowest, and those of the group of aged 10-12 years were all the highest (all P<0.05). There had no statistically differences in the contact time percentage values of the bilateral midfoot among the 3 age groups (all P>0.05). There all had statistically differences in the contact time percentage values of the bilateral hindfoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all lower than those of the other two groups (all P<0.05). Conclusion:Plantar pressure parameters exhibit distinct age-related patterns, reflecting the development of gait patterns and foot arch formation, which will be useful for monitoring physical growth and sports rehabilitation.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.
