Objective: To assess the causal association between specific oral microbiota and the risk of oral leukoplakia (OLK) using a Mendelian randomization (MR) approach, and to elucidate the potential mediating role of immune cells. Methods: Summary statistics from genome-wide association studies (GWAS) of the oral microbiome, GWAS data for immune cell phenotypes, and GWAS summary statistics for OLK from FinnGen were used. The inverse variance weighted (IVW) method was adopted as the primary approach, and it was supplemented by MR Egger regression, simple mode, weighted median, and weighted mode methods for additional analyses, to investigate the causal relationship between 3 117 types of tongue coating and salivary microbiota, as well as 731 immune cell traits, and OLK. Furthermore, a two-step MR approach was applied to explore the potential mediating role of immune cells in the association between oral microbiota and OLK. Results: IVW analysis revealed causal associations between 15 oral microbial genera and OLK. Among these, Streptococcus, Neisseria, and Catonella were associated with a reduced risk of OLK, with Fusobacterium showing the most significant protective effect (OR = 0.41, P = 0.023). In contrast, genera, including Microbacterium, Campylobacter, and Haemophilus_A, were linked to an increased risk of OLK, with Lancefieldella exhibiting the strongest risk effect (OR = 2.66, P = 0.006). Eleven immune cell phenotypes with potential causal associations with OLK were identified, including four protective and seven risk-increasing factors. Mediation analysis further identified four key mediating pathways: pathogenic genera, particularly Campylobacter_A and Lancefieldella, may promote the development and progression of OLK by upregulating highly activated pro-inflammatory immune subsets such as activated monocytes, B cells, and myeloid cells. Conversely, the potentially protective genus Catonella appeared to exert inhibitory effects on OLK by significantly downregulating dendritic cell subsets. Conclusion This study is the first to reveal, at the genetic level, causal pathways through which specific oral microbial genera influence the risk of OLK by mediating immune cell responses. These findings provide novel insights into the immunopathological mechanisms underlying OLK and offer potential targets for intervention strategies aimed at modulating specific microbial genera or immune cell subsets.

Objective: To explore the effects of microwave radiation on cognitive function and neuroinflammation in mice with experimental periodontitis, providing experimental evidence for understanding how environmental exposure may be linked to the risk of neurodegenerative diseases by modulating chronic inflammation as a shared pathological mechanism Methods: This study was approved by the Animal Ethics Committee of the Academy of Military Medical Sciences. C57BL/6J mice were randomly divided into a control group (C group, untreated), a microwave radiation group (R group, exposed to microwave radiation only), a periodontitis group (P group, ligation-induced periodontitis only), and a periodontitis + microwave radiation group (PR group, ligation-induced periodontitis plus microwave radiation exposure). A periodontitis model was established using the silk ligation method. Eight weeks after modeling, the R and PR groups were subjected to whole-body microwave radiation at 2 800 MHz and 10 mW/cm2 for 10 h/day for 7 consecutive days. Behavioral tests were conducted: the open field test and elevated plus maze test were used to assess anxiety-like behavior, the Y-maze test to evaluate spatial memory, and the novel object recognition test to assess learning and memory abilities. Micro-CT, hematoxylin & eosin staining (HE), and quantitative real-time polymerase chain reaction (qPCR) were used to analyze periodontal tissue pathology and local inflammation. Serum and brain levels of lipopolysaccharide (LPS), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were measured using enzyme-linked immunosorbent assay (ELISA). The composition of the oral microbiota was analyzed based on 16S rRNA sequencing. Results: Behavioral tests showed that anxiety-like behavior was significantly exacerbated in the R and PR groups, and spatial and recognition memory impairments in the PR and P groups were more severe compared with the R and C groups, respectively (P < 0.05). Histological and molecular biological analyses revealed that periodontal inflammation infiltration, alveolar bone resorption, and local expression of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) were further exacerbated in the PR and P groups compared with the R and C groups, respectively (P < 0.05). ELISA results showed that in serum, LPS levels in group P and group PR were increased compared with group C and group R, respectively. The levels of TNF-α, IL-1β, and IL-6 in group PR were significantly higher than those in group P and group R, with a synergistic increase in TNF-α level (P < 0.05). In brain tissue, LPS and TNF-α, IL-1β, IL-6 levels in group P were significantly higher than those in group C; all the above indicators in group PR were significantly higher than those in group P and group R, and LPS and IL-6 levels showed a synergistic increase (P < 0.05). Oral microbiota analysis found that microwave radiation further reduced microbial diversity on the basis of periodontitis, leading to increased relative abundances of Lactobacillus and Enterococcus, and decreased relative abundances of Staphylococcus. Correlation analysis confirmed that these differential bacterial genera were positively correlated with brain inflammation levels and negatively correlated with cognitive function indicators. Conclusion Microwave radiation exposure can exacerbate cognitive impairment in mice with experimental periodontitis, and its mechanism may be related to aggravated local periodontal damage, disruption of oral microbiota homeostasis, and subsequent induction of systemic and central neuroinflammatory cascades.

Locoregional therapy （LRT）， including transarterial chemoembolization， transarterial radioembolization， and various ablation techniques， is an important treatment method for hepatocellular carcinoma. Many studies in recent years have confirmed that LRT has a dual regulatory effect on tumor immune microenvironment. While LRT induces immunogenic cell death， activates dendritic cell-mediated and T cell-driven immunity， and triggers systemic antitumor responses， it concomitantly upregulates the adenosine signaling pathway， promotes the accumulation of TREM2⁺ macrophages， and enhances the expression of immunosuppressive factors， thereby forming an immunosuppressive microenvironment. At present， the combination of LRT and immune checkpoint inhibitors has shown a promising future and has promoted the exploration of novel targets within treatment-associated immunosuppressive pathways， such as adenosine， TREM2⁺ macrophages， and IL-6. This article summarizes the dual regulatory effect of LRT on immune microenvironment and highlights that multi-omics techniques and clinical trials should be used in the future to decipher its dynamic alterations， in order to optimize combination strategies， realize individualized precise treatment， and improve the prognosis of patients.

Background Diesel engines are widely used in transportation, agriculture, construction, industry, and other fields. Diesel exhaust, classified as a Group 1 carcinogen, emits particles (DEP) that can penetrate deep into the respiratory tract, posing significant health risks. DEP pollution is particularly severe in confined environments, necessitating effective control measures. Objective Under laboratory simulation conditions, to explore the spatiotemporal distribution characteristics of the mass and number concentrations of DEP as it diffuses indoors and to reveal the effects of ventilation and additional airflow on indoor DEP pollution levels. Methods A diesel engine was placed in a laboratory (length 3.39 m × width 2.85 m × height 2.4 m) with its exhaust emitted from east to west. An air purifier was installed 1 m south of the engine. Eight measurement points (1 m horizontal distance from the exhaust outlet, height: 1 m/1.5 m) were setup to monitor DEP concentrations using portable laser particle sizers. The effects of engine power (4.05 kW vs. 5.15 kW), ventilation (maximum airflow: 600 m³·h⁻¹), additional airflow intensity (low and high), and direction (forward/reverse) on DEP pollution were analyzed. DEP levels of 5 diesel vehicle models were also compared. Results The mass and number concentrations of DEP indoors increased immediately after the diesel engine started. The peak mass concentration time at the eastern measurement point (−1, 0) m opposite to the exhaust direction (17.70 min) was significantly longer than that at the western (1, 0) m (16.20 min), southern (0, -1) m (14.45 min), and northern (0, 1) m (12.70 min) points (P<0.05), with no significant differences between the other points (western, southern, and northern) (P>0.05). The northern point (0, 1) m exhibited the highest DEP mass and number concentration peaks (174.62 μg·m⁻³, 1319.85 p·cm⁻³), significantly exceeding those at the southern (0, −1) m (129.89 μg·m⁻³, 1175.24 p·cm⁻³), eastern (−1, 0) m (140.12 μg·m⁻³, 1120.53 p·cm⁻³), and western (1, 0) m (147.60 μg·m⁻³, 818.62 p·cm⁻³) points (P<0.05), and no significant differences were observed among other points (P>0.05). There were no significant differences in peak DEP mass and number concentrations by measurement heights (P>0.05). Diesel engine power, ventilation, airflow intensity, and airflow direction had no significant effect on the time of peak DEP concentration (P>0.05). However, higher engine power (5.15 kW) produced greater DEP peaks [(186.66±19.29) μg·m⁻³, (1382.79±122.56) p·cm⁻³] than the 4.05 kW engine power [(168.41±12.65) μg·m⁻³, (1284.45±71.30) p·cm⁻³] (P<0.05). The peak mass concentration [(342.04±35.03) μg·m⁻³] and number concentration [(1886.87±57.91) p·cm⁻³] of DEP in the non-ventilated group were significantly higher than those in the ventilated group [(186.66±19.29) μg·m⁻³, (1382.79±122.56) p·cm⁻³] (P<0.001). Forward airflow elevated DEP mass concentrations compared to reverse airflow (287.71 μg·m⁻³ vs. 243.74 μg·m⁻³, t=−2.592, P=0.009), but no effects on DEP number concentration (P>0.05). Significant differences in mass concentration were observed among selected 5 vehicle models (Z=38.109, P<0.001). Conclusion The operation of diesel engines will emit a large amount of particulate matter, causing pollution in enclosed spaces. Diesel engines with greater power have higher levels of DEP pollution emissions. Based on the spatiotemporal distribution characteristics, it is recommended to set the operation position in the reverse direction of exhaust emissions and close to air purifiers, while avoiding the use of additional air flow equipment.

Objective To explore the immediate recanalization efficacy of flexible endoscopy-assisted retrograde ureteral catheterization for uretero-ileal anastomotic stenosis after Bricker ileal bladder surgery.Method A retrospective analysis was conducted on the clinical data of 17 patients who underwent Bricker ileal bladder surgery in the hospital from November 2016 to October 2022.There were a total of 28 sites of ureterileal anastomotic stenosises,all of which were treated with flexible endoscopy-assisted retrograde ureteral catheterization.Result There were 21 sites who successfully underwent recanalization after endoscopic treatment,the median length of hospital stay was 6(4.75,8.50)days.Among the 28 uretero-ileal anastomotic stenosises,21 sites were successfully recanalized immediately under endoscopy(10 on the left and 11 on the right),while 7 sites failed to recanalize immediately under endoscopy(4 on the left and 3 on the right).The 21 sites of successful immediate recanalization under endoscopy include:15 sites of simple retrograde placement of ureteral catheters,1 site of endoscopic ureterileal anastomotic dilation,net basket stone removal and retrograde stent placement,3 sites of retrograde ureteral stent placement under ultra-fine endoscopy,and 2 sites of retrograde ureteral stent placement under duodenoscopy.The total operation time of all patients was less than 50 minutes.Among the 17 patients,the urine drainage of the ureteral stent was unobstructed.There were varying degrees of abrasions and a small amount of bleeding at the bladder ileal and ureterileal anastomoses.No serious complications such as delayed bleeding,perforation,severe urinary tract infection,stent blockage or displacement occurred.Conclusion Flexible endoscopy-assisted retrograde ureteral catheterization are safe and effective for immediate recanalization of uretero-ileal anastomotic stenosis.It is worth applying in clinical practice.

Objective:To investigate whether changes in CT pulmonary angiography (CTPA) parameters before and after balloon pulmonary angioplasty (BPA) are correlated with treatment effects in patients with chronic thromboembolic pulmonary hypertension (CTEPH).Methods:A retrospective study was conducted, including patients with CTEPH who underwent BPA treatment at Beijing Anzhen Hospital from November 2021 to Febbruary 2024. Clinical data and CTPA parameters were analyzed before the initial BPA session and at least 6 months after the final BPA session. Clinical data included WHO functional class, 6-minute walk distance (6MWD), and plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) levels. The CTPA parameters included the widest diameter of the pulmonary artery diameter (dPA), ascending aorta diameter (dAA), the widest transverse diameter of the right atrium (dRA), the widest short-axis diameter of the right ventricle (dRV), the widest short-axis diameter of the left ventricle (dLV), and the diameter of right ventricular free wall thickness(dRVW). Multiple linear regression was applied to identify variables associated with the decrease in mean pulmonary artery pressure (mPAP) among the CTPA parameters.Results:All CTEPH patients underwent a total of 115 BPA treatments. Postoperatively, the WHO functional class of the patients improved compared to preoperative levels ( χ2=5.01, P<0.001), 6MWD improved ( t=4.50, P<0.001), and NT-proBNP levels decreased ( Z=4.47, P<0.001). Hemodynamic parameters, including mPAP, pulmonary vascular resistance, cardiac output, and cardiac index, were significantly improved postoperatively (all P<0.001). CTPA-related parameters, including dPA, dRA, dRV, dRVW, dPA/dAA, dRV/dLV, and dRA/dPA, significantly decreased compared to preoperative values (all P<0.001). Multiple linear regression analysis showed that the decrease in dPA ( β=0.314, P=0.037) and dRA ( β=0.334, P=0.046) were significantly correlated with the improvement in mPAP. Conclusions:Exercise tolerance, hemodynamics, and CTPA parameters in patients with CTEPH significantly improved after BPA treatment. The decrease in dPA and dRA were significantly correlated with the improvement in mPAP, suggesting that CTPA is a potentially novel, objective, effective, and noninvasive method for evaluating the therapeutic efficacy of BPA.

Toxoplasmosis is a zoonotic disease caused by infection with Toxoplasma gondii. Congenital toxoplasmosis is a common form of intrauterine infection and is associated with severe neurological sequelae such as cerebral palsy and cognitive impairment. This report presented the magnetic resonance imaging (MRI) features of a fetal intracranial toxoplasmosis case, including bilateral ventriculomegaly, multiple intracranial cystic lesions, and parenchymal calcifications, without concurrent retinal abnormalities or hepatosplenomegaly. Post-termination analyses confirmed the presence of T.gondii DNA in amniotic fluid and umbilical venous blood, with histopathology revealing necrosis and eosinophilic infiltration. MRI demonstrates superior soft-tissue resolution in evaluating the extent of cerebral lesions and parenchymal damage, underscoring its diagnostic value in fetal toxoplasmic encephalopathy.

Objective:To investigate the clinical characteristics and risk factors associated with secondary systemic capillary leak syndrome (SSCLS) induced by acute organophosphorus pesticide poisoning (AOPP). The goal is to enhance clinical understanding of this complication and provide a theoretical foundation for the early identification of high-risk patients and the optimization of individualized treatment strategies.Methods:Clinical data were collected from patients admitted to the Emergency Department of Fuyang People’s Hospital Affiliated to Anhui Medical University between October 2019 and October 2024, who were diagnosed with acute dichlorvos poisoning. The clinical features of SSCLS were described, and patients were categorized into SSCLS and non-SSCLS groups. Binary multivariate logistic regression analysis was conducted on statistically significant indicators to identify independent risk factors for SSCLS. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive value of these factors.Results:Among the 96 patients studied, 37 (38.5%) developed SSCLS. The median time from toxin ingestion to the onset of SSCLS was 3.0 (2.0-5.0) hours. In the 14 SSCLS survivors, the median duration of SSCLS was 50.0 (24-72) hours, whereas in the 23 non-survivors, it was 24.0 (12.0-35.0) hours. The mortality rate in the SSCLS group (62.16%, 23/37) was significantly higher than that in the non-SSCLS group (1.69%, 1/59) ( χ2=44.343, P<0.001). Blood toxin analysis detected trichlorfon components in 92 patients (95.83%). Binary multivariate logistic regression identified APACHE Ⅱ score and trichlorfon concentration (≥706.35 ng/mL) as independent risk factors for SSCLS ( P<0.05). ROC analysis revealed that the combination of these two factors had a higher predictive value ( P<0.05). Conclusions:In the diagnosis and treatment of acute dichlorvos (organophosphorus pesticide) poisoning, particular attention should be given to the combined toxic effects of dichlorvos and trichlorfon, which can lead to SSCLS. The onset and progression of SSCLS are rapid, and the condition is associated with a high mortality rate. Both APACHE Ⅱ scores and trichlorfon concentrations (≥706.35 ng/mL) are independent risk factors for the development of SSCLS, and their combined use enhances predictive accuracy. Early identification of high-risk patients and timely administration of individualized treatment are critical for reducing mortality rates. This revised abstract maintains the original meaning while improving clarity, flow, and readability. It ensures that the key points are presented in a structured and professional manner, suitable for a clinical audience.
