A case of maxillary sinus cyst removal via lateral wall fenestration combined with sinus floor elevation and implant placement was reported.A 52-year-old female presented with bilateral posterior maxillary tooth loss.Preoperative CBCT revealed two dome-shaped pseudocysts at the right maxillary sinus floor,with intact sinus walls.During surgery,lateral wall fenestration was performed,followed by cyst aspiration and removal.The sinus mucosa was repaired using an absorbable collagen barrier membrane(Bio-Gide?),and deprotein-ized bovine bone matrix(Bio-Oss?)was implanted for bone augmentation.Postoperative CBCT at 9 months showed ideal bone height and density at the sinus floor,with no cyst recurrence and successful osseointegration of implants.The results suggest that concurrent cyst re-moval during sinus floor elevation could achieve stable bone augmentation when large cysts compromise the procedure.

Objective:To detect the microbial signals in the synovial fluid from knee osteoarthritis (KOA) patients using long-read metagenomic sequencing and assess the impact of intra-articular injection of sodium hyaluronate on the detection.Methods:This retrospective study enrolled 28 KOA patients [set as a KOA group: 13 males, 15 females; mean age of (65.5±5.7) years] who had undergone primary total knee arthroplasty (TKA) or unicompartmental knee arthroplasty (UKA) at Department of Knee Joint Surgery, Honghui Hospital between January 2021 and January 2023. At the same time, samples of instrument cleaning water used for the 28 KOA patients were collected (set as a rinse solution group), and the knee synovial fluid was collected from 10 healthy adult volunteers [set as a control group: 5 males and 5 females; mean age of (29.7±12.1) years]. The KOA patients were stratified into an injection group ( n=5) and a non-injection group ( n=23) according to the history of injection of sodium hyaluronate within 6 months before operation. All samples were subjected to standard procedures for nucleic acid extraction and Oxford Nanopore Technologies (ONT) metagenomic sequencing to compare microbial taxa and detection frequencies. Results:No periprosthetic joint infections or infection-related clinical events occurred in the KOA patients during the 12-month postoperative follow-up. A total of 10 microbial species (30 isolates) were identified in the KOA synovial fluid (5 Gram-positive and 5 Gram-negative). The species with the top 5 detection rates were Escherichia coli (20.0%), Propionibacterium spp. (20.0%), Staphylococcus spp. (16.7%), Acinetobacter spp. (13.3%), and Pseudomonas spp. (6.7%). From the samples in the rinse solution group, 9 species (11 isolates) were detected, reflecting background contamination. All the joint fluid from the healthy volunteers in the control group was negative. Six species of microorganisms were detected in the injection group while 3 species in the non-injection group, showing a statistically significant difference ( P<0.001). Conclusions:Long-read metagenomic sequencing detects diverse microbial signatures in the synovial fluid from KOA patients, and preoperative injection of sodium hyaluronate is associated with increased detection of microbial species.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Ancient traditional Chinese medicine (TCM) doctrine says "The superior doctor prevents illnesses," pointing out preventative medicine as the ultimate goal for medical care. TCM recognizes that genetic predisposition and environmental and lifestyle influences contribute to diseases. It divides people into eight constitutions in addition to one normal/healthy kind. People with one of the eight subhealth constitutions are prone to develop different kinds of corresponding illnesses. The goal for this type of categorization is to help people take preemptive measures to prevent or delay disease onset. As the peripheral immune system through surveying the body, it can capture information from essentially all organs and reflect anomalies occurring in each organ. Thus, the detailed profiling of the peripheral immune-system function can generally reflect a person's overall heath state. In this study, we performed the single-cell RNA sequencing (scRNA-seq) of peripheral blood mononuclear cells (PBMCs) from individuals with Tanshi (phlegm dampness) constitution. They were prone to develop metabolic disorders including diabetes. scRNA-seq revealed greatly reduced mucosal-associated invariable T cell content and heightened TNFα-NFκB, JAK-STAT, and interferon signaling. These findings indicated heightened chronic inflammation, as well as increased hypoxia/apoptosis responses, likely resulting from frequent sleep apnea that Tanshi individuals experienced. Altogether, this pilot study demonstrated effectiveness in using scRNA-seq to reveal molecular-immunological bases for constitution categorization, thereby substantiating that preventative medicine originated from TCM.

BACKGROUND: Previous evidence showed that ambient air pollution and cardiovascular mortality are related. However, there is a lack of evidence towards the modification effect of long-term lifestyle on the association between short-term ambient air pollution and death from cardiovascular events. METHOD: A total of 14,609 death from major adverse cardiovascular events (MACE) were identified among the China Kadoorie Biobank participants from 2013 to 2018. Ambient air pollution exposure including particulate matter 2.5 (PM_2.5), SO₂, NO₂, CO, and O₃ from the same period were obtained from space-time model reconstructions based on remote sensing data. Case-crossover design and conditional logistic regression was applied to estimate the effect of short-term exposure to air pollutants on MACE mortality. RESULTS: We found MACE mortality was significantly associated with PM_2.5 (relative percent increase 2.91% per 10 µg/m³ increase, 95% CI 1.32-4.53), NO₂ (5.37% per 10 µg/m³ increase, 95% CI 1.56-9.33), SO₂ (6.82% per 10 µg/m³ increase, 95% CI 2.99-10.80), and CO (2.24% per 0.1 mg/m³ increase, 95% CI 1.02-3.48). Stratified analyses indicated that drinking was associated with elevated risk of MACE mortality with NO₂ and SO₂ exposure; physical inactivity was associated with higher risk of death from MACE when exposed to PM_2.5; and people who had balanced diet had lower risk of MACE mortality when exposed to CO and NO₂. CONCLUSIONS The study results showed that short-term exposure to ambient PM_2.5, NO₂, SO₂, and CO would aggravate the risk of cardiovascular mortality, yet healthy lifestyle conduct might mitigate such negative impact to some extent.

Objective: To explore the effects of sleep on subsequent day physical activity (PA) in children and adolescents, so as to provide a reference for refining PA intervention strategies and further investigating their underlying mechanisms. Methods: Through searching databases including Web of Science Core Collection, PubMed, EBSCOhost, ScienceDirect, Cochrane Library, CNKI, Wanfang and VIP cross sectional, cohort and experimental studies on sleep and subsequent day PA among children and adolescents were identified, with the searching period spanning from database inception to June, 2025. Based on the characteristics of the included literature, two sleep variables[sleep duration (SD) and sleep efficiency (SE)] and three physical activity variables[moderate to vigorous physical activity (MVPA), light physical activity (LPA), and total physical activity (TPA)] were selected. The relationship between these two types of variables was analyzed for pooled effect sizes using Stata 17.0. Results: A total of 14 studies were included, with 64.3% published in 2018 or later, involving 11 361 children and adolescents from 17 countries. Meta analysis results showed that both SD ( ES=0.04, 95%CI =0.01-0.07) and SE ( ES=0.24, 95%CI =0.01-0.47) were positively correlated with subsequent day MVPA (both P <0.05). However, no statistically significant associations were found with LPA ( ES=-0.04, 95%CI =-0.13 to 0.06; ES=-0.02, 95%CI =-0.15 to 0.11) or TPA( ES=0.09, 95%CI =-0.02 to 0.20; ES=0.02, 95%CI = -0.03 to 0.06)(all P >0.05). Subgroup analysis revealed that in the "≤6 years" subgroup, SD and SE were positively correlated with TPA ( ES=0.22, 95%CI =0.09-0.35) and MVPA ( ES=1.19, 95%CI =1.06-1.32), respectively; in the "6-12 years" subgroup, SD was positively correlated with MVPA ( ES=0.05, 95%CI =0.02-0.08); in the "≥12 years" subgroup, SE was positively correlated with LPA ( ES=0.08, 95%CI =0.00-0.16), while SD was negatively correlated with LPA ( ES=-0.23, 95%CI = -0.31 to -0.16) (all P <0.05). Conclusion Adequate SD and good SE can effectively enhance subsequent day MVPA among children and adolescents, although these sleep effects vary by age group.

Objective To investigate the correlation between serum cytotoxic T lymphocyte associated pro-tein 4(CTLA4),high mobility group box 1(HMGB1)and the balance of helper T cell 17(Th17)/regulatory T cell(Treg),and to study their diagnostic significance for unexplained recurrent spontaneous abortion(URSA).Methods A total of 102 patients with URSA admitted to the hospital from September 2022 to September 2024 were selected as the URSA group,and another 80 healthy pregnant women who underwent prenatal examinations in the hospital during the same period were selected as the healthy group.The levels of serum CTLA4 and HMGB1 in the two groups were detected,the levels of Th17 and Treg in the two groups were detected,the Th17/Treg ratio was calculated,and the general data of the two groups were collected and recorded.Pearson was used to analyze the correlations between the levels of serum CLTA4 and HMGB1 and Th17,Treg,and Th17/Treg.logistic regres-sion was used to analyze the influencing factors of URSA occurrence.The receiver operating characteristic(ROC)curve was used to analyze the value of serum CTLA4 and HMGB1 levels in evaluating the occurrence of URSA.Results the serum CTLA4 level in the URSA group was lower than that in the healthy group,the HMGB1 level was higher than that in the healthy group,the Th17 level and Th17/Treg were higher than those in the healthy group,and the Treg level was lower than that in the healthy group(P<0.05).The serum CTLA4 level was nega-tively correlated with the Th17 level and Th17/Treg,and positively correlated with the Treg level(P<0.05).The level of HMGB1 was positively correlated with the level of Th17 and Th17/Treg,and negatively correlated with the level of Treg(P<0.05).Pregnancy frequency,serum CTLA4 level,serum HMGB1 level,Th17 level,Treg level,and Th17/Treg are independent influencing factors for the occurrence of URSA(P<0.05).The areas under the curve(AUC)of serum CTLA4 and HMGB1 levels and the combined evaluation of URSA by the two indicators were 0.841,0.787,and 0.908 respectively,and the Youden indices were 0.652,0.491,and 0.656 respectively.Conclusions The serum CTLA4 level is decreased and the HMGB1 level is increased in patients with URSA,which is related to the change of Th17/Treg balance.The levels of serum CTLA4 and HMGB1 have auxiliary diag-nostic significance for URSA.
