Postoperative cognitive dysfunction (POCD) is a clinically significant complication in elderly patients, largely driven by surgery-induced neuroinflammation. The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway, a crucial regulator of innate immunity, has been implicated in neuroinflammatory activation. This study investigated whether electroacupuncture (EA) improves POCD by modulating this pathway in aged rats. Aged male Sprague-Dawley rats were subjected to sevoflurane anesthesia and splenectomy to establish a POCD model. Animals were divided into sham, POCD, POCD+EA, and POCD+EA+cGAS inhibitor groups. The EA groups received stimulation at Baihui (Governor Vessel 20 (GV20)), Neiguan (Pericardium 6 (PC6)), and Zusanli (Stomach 36 (ST36)) acupoints. Cognitive function was evaluated using the Morris water maze, while hippocampal expression of cGAS-STING pathway components and downstream effectors—interferon regulatory factor 3 (IRF3), nuclear factor kappa B (NF-κB), and interleukin-1 beta (IL-1β)—was assessed by Western blot. Cellular localization was determined by immunofluorescence staining. Compared with the Sham group, rats in the POCD group showed significant impairments in spatial memory, accompanied by upregulated protein expression of cGAS, STING, NF-κB, IRF3, and IL-1β in the hippocampus. Upon pathway activation, cGAS and STING proteins were predominantly co-localized with neurons, and their fluorescence intensity in the hippocampus was markedly increased. These behavioral deficits and molecular alterations were partially reversed in both the POCD+EA and POCD+EA+inhibitor groups. Electroacupuncture alleviates POCD in aged rats by inhibiting hippocampal cGAS-STING pathway activation and reducing neuroinflammation, suggesting a promising non-pharmacological strategy for POCD management.

Metabolic dysfunction-associated fatty liver disease （MAFLD） has become the most common chronic liver disease worldwide. Its pathological process is centered on the “two-hit” theory， with gut-liver axis dysregulation running through the entire disease course from steatosis to liver cirrhosis and even hepatocellular carcinoma， and it forms an extensive cross-system regulatory mechanism with the metabolic， cardiovascular， renal， and psychological and nervous systems through multi-dimensional pathways such as the “gut-liver-brain axis”， the “liver-kidney axis”， and the “liver-heart axis”. Disease progression is not limited to the liver itself， and it also involves functional imbalance of multiple organ systems throughout the body. This article systematically elaborates on the association mechanism of “liver pathological progression-multi-axis regulation-comorbidity occurrence” in MAFLD， proposes synergistic management strategies integrating early screening based on risk stratification， targeted intervention， and multidisciplinary diagnosis and treatment， and analyzes the limitations of current research and future development directions， in order to provide a theoretical basis and practical guidance for precise diagnosis and treatment and individualized management of MAFLD.

Objective To explore the efficacy of total laparoscopic subtotal colectomy with transrectal specimen retrieval for the treatment of slow transit constipation(STC).Methods A total of 18 patients with STC underwent laparoscopic subtotal colectomy with transrectal specimen retrieval from June 2022 to December 2024.A portion of the ileocecal region was reserved.The colon specimen was removed from the rectum and anus,and ileocecal rectal anastomosis was performed.The efficacy of treatment was evaluated by using the Wexner constipation score and Gastrointestinal Quality of life index(GIQLI).Results All the operations in the 18 patients were completed smoothly.There was no conversion to laparotomy or addition of abdominal wall incision for specimen retrieval.The operation time was240-480 min(median,360 min),the intraoperative blood loss was 20-100(median,60 ml),and the length of the resected intestinal tube was 70-110 cm(median,95 cm).The gastrointestinal function recovery time of the patients after surgery was 1-3 d(median,2 d),and the hospital stay was 8-13 d(median,10 d).All the patients recovered smoothly after surgery,without serious complications such as anastomotic leakage and abdominal infection.The Wexner constipation score at 6 months after surgery was(5.7±2.8)points,which was significantly lower than the preoperative score[(16.2±2.1)points,t=21.401,P=0.000].The GIQLI score at6 months after surgery was(114.9±9.1)points,which was significantly higher than the preoperative score[(85.2±7.2)points,t=-28.865,P=0.000].Conclusions Total laparoscopic subtotal colectomy with transrectal specimen retrieval is effective for STC.The patients'defecation status and quality of life are improved after surgery,which has certain clinical promotion value.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective To analyze the epidemiological characteristics and disease burden of drug-resistant tuberculosis cases among elderly patients in Wuhan.Methods Clinical data of elderly pa-tients with pulmonary tuberculosis in Wuhan from January 2019 to December 2022 were retrospectively analyzed.Sputum samples were collected for Mycobacterium tuberculosis isolation,and drug suscepti-bility testing was performed using the proportion method.The epidemiological characteristics of drug-resistant tuberculosis and the direct economic burden of the patients were analyzed.Results A total of 972 elderly patients with positive Mycobacterium tuberculosis tests were included.The overall tuberculosis drug resistance rate was 21.19％(206/972).Male,rural residence,lower education level(primary school or below)and retreatment history significantly increased the risk of developing drug-resistant tu-berculosis(P＜0.05).The direct economic burden for elderly patients with drug-resistant tuberculosis was 24,101.52(8,283.98,39,598.89)RMB,and the indirect economic burden was 1,858.64(528.66,3,085.26)RMB.Conclusion The incidence of drug resistance in elderly tuberculosis is high,and male,rural residence,low education level and tuberculosis retreatment are the risk factors for drug resistance in elderly tuberculosis,and their economic burden is heavy after drug resistance.

Objective To investigate the age-dependent modulatory effects of treadmill exercise on spatial learning and memory in mice and to elucidate the potential neurobiological mechanisms underlying these effects.Methods Male C57BL/6J mice at three distinct developmental stages were subjected to a controlled treadmill training protocol for a duration of four weeks.Cognitive performance was assessed in terms of spatial learning and memoryusing a series of behavioral tests.To examine exercise-induced neurogenesis,proliferating adult neural stem cells in the hippocampal region were labeled via intraperitoneal administration of BrdU.Meanwhile,physiological parameters,including body and muscle weight,were monitored throughout the experiment.Results The study revealed significant age-specific effects of treadmill training.In one-month-old mice,exercise intervention markedly enhanced spatial learning and memory,along with increased proliferation of hippocampal neural stem cells,but no significant alterations were observed in body or muscle weight.In six-month-old mice,treadmill training selectively improved spatial memory and led to increased muscle weight.Notably,three-month-old mice exhibited no significant exercise-induced changes in cognitive performance,hippocampal neurogenesis,or muscle weight.Conclusion These findings demonstrate that treadmill exercise exerts significant,age-dependent regulatory effects on spatial learning and memory,with the most pronounced and comprehensive improvements observed in one-month-old mice.The cognitive enhancements may be mediated,at least partially,through exercise-induced promotion of hippocampal neurogenesis.This study provides data for elucidation of the mechanistic basis of exercise-mediated cognitive enhancement and contributes to the potential applications of exercise interventions in cognitive optimization and neuroplasticity across different developmental stages.

ObjectiveTo investigate the seroprevalence of Japanese encephalitis virus (JEV) IgG antibodies among the healthy individuals in Huzhou City, Zhejiang Province, so as to provide a scientific basis for the development of prevention and control strategies for Japanese B encephalitis (JE). MethodsA cross-sectional study was conducted from 2023 to 2024. Serum samples were collected from healthy individuals across 12 age groups (<8 months, 8 months‒<2 years, 2‒<4 years, 4‒<6 years, 6‒<8 years, 8‒<10 years, 10‒<15 years, 15‒<20 years, 20‒<30 years, 30‒<40 years, 40‒<50 years, 50‒ years) and tested for JEV IgG antibody to determine positivity rates. ResultsThe overall JEV IgG antibody seroprevalence rate was 57.75 % among the healthy individuals in Huzhou City. The positivity rates for the age groups of <8 months, 8 months‒<2 years, 2‒<4 years, 4‒<6 years, 6‒<8 years, 8‒<10 years, 10‒<15 years, 15‒<20 years, 20‒<30 years, 30‒<40 years, 40‒<50 years, and 50‒ years were 10.14%, 23.76%, 77.31%, 66.88%, 73.87%, 58.33%, 41.67%, 55.06%, 47.00%, 61.00%, 62.00%, and 92.00%, respectively, with a statistically significant difference observed in different age groups (χ²=243.996, P<0.001). Seroprevalence rates also differed significantly between males and females (χ²=9.999, P=0.002). Among subjects vaccinated with 0,1 or 2 doses of live attenuated Japanese encephalitis virus vaccine (JEV-L), the IgG antibody seroprevalence rate was 4.76%, 27.27% and 72.33%, respectively (χ²=108.568, P<0.001). Within the 2 doses group, the IgG antibody seroprevalence rate at <1 year, 1 year, 2 years and 3‒5 years after immunization were 80.85%, 77.36%, 66.67% and 65.45%, respectively, indicating a declining trend with time increased since vaccination (Z=-2.024, P=0.043). ConclusionAdults aged 50‒ years maintain high antibody levels, whereas levels are lower among the age groups of <2 years and 8‒<30 years and wane with time since vaccination in Huzhou City. It is recommended to maintain the routine JE vaccination schedule while exploring booster vaccination strategies for the age groups of 8‒<30 years, in order to enhance population immunity against JEV.

Purpose To investigate the diagnostic value of immunohistochemical(IHC)and molecular markers in diffuse pleural mesothelioma(DPM).Methods A total of 114 cases of DPM were retrospectively analyzed for clinical and imaging manifestations,histologic subtype and tumor grade.The positivity rates of Calretinin,WT-1,CK5/6,MC,D2-40,UPK3B,and GATA3 were assessed by IHC,and the loss rates of BAP-1 and MTAP were determined.The concordance between MTAP IHC and p16 gene fluorescence in situ hybridization(FISH)status was calculated,a-long with the sensitivity and specificity of MTAP IHC relative to p16 FISH.Results Among the 114 DPM patients,66(57.9％)were male and 48(42.1％)were female,with a mean age of 58.1 years(range 16-85 years).Imaging predominantly demonstrated pleural effusion and multiple pleural nodules(55.3％,63/114).Histologically,epitheli-oid,sarcomatoid and biphasic subtypes accounted for 88(77.2％),17(14.9％)and 9(7.9％)cases,respectively.Within the epithelioid group,low and high-grade tumors numbered 69(78.4％)and 19(21.6％),respectively.In epithelioid DPM,the highest IHC positivity rates were observed for Calretinin(92.4％,81/88),D2-40(90.0％,79/88)and WT-1(90.0％,79/88).In sarcomatoid DPM,D2-40(76.5％,13/17),WT-1(64.7％,11/17),and Cal-retinin(29.4％,5/17)showed the greatest positivity.UPK3B was positive in epithelioid(59.1％,39/66)and bi-phasic cases(66.7％,4/6),but was absent in sarcomatoid tumors(0/12).Among all DPM cases,loss rates were 47.3％(53/112)for BAP-1 and 19.2％(20/104)for MTAP by IHC,p16 gene deletion by FISH was 31.5％(34/108);Concordance between MTAP IHC and p16 FISH was 81.0％(81/100);MTAP IHC had a specificity of 95.5％(64/67)and sensitivity of 51.5％(17/33)relative to p16 FISH.Additionally,GATA3 was highly expressed in sarco-matoid DPM(76.5％,13/17).UPK3B positivity differed significantly between thoracoscopic DPM(59.2％,32/54)and percutaneous biopsy samples(36.7％,11/30)in epithelioid DPM(P＜0.05).WT-1 positivity was higher in thoracoscopic than percutaneous samples of sarcomatoid DPM(90.0％ vs 28.6％,P=0.009).Conclusion Calreti-nin,D2-40,and WT-1 are highly sensitive mesothelial markers and should serve as first-line IHC stains in DPM diag-nosis.UPK3B is diagnostically valuable in epithelioid DPM,GATA3 may complement the diagnosis of sarcomatoid DPM,and MTAP IHC can be used as a surrogate or adjunct to p16 FISH.
