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.

Psychological factors have become significant contributors to the onset and progression of insomnia. This article explored the treatment of insomnia from the perspective of “liver governs wei qi （defensive qi）”. The concept of “liver governs wei qi （defensive qi）” is summarized in three aspects， firstly， the liver assists the spleen and stomach in transformation and transportation， governing the generation of wei qi； secondly， the liver aids lung qi diffusion and dispersion， governing the distribution of wei qi； thirdly， the liver regulates circadian rhythms， governing the circulation of wei qi. It is proposed that the clinical treatment of insomnia should focus on the following methods： for regulating the liver to harmonize the five viscera， and facilitate the circulation of wei qi， medicinals entering the liver channel include Chaihu （Bupleuri radix）， Baishao （Paeoniae Radix Alba）， Zhizi （Gardeniae Fructus）， and Suanzaoren （Ziziphi Spinosae Semen） could be commonly used； for nourishing the liver， the treatment should align with the day-night rhythm， and herbs such as Baihe （Lilium）， Hehuan （Albizia julibrissin）， and Yejiaoteng （Polygoni multiflori caulis） are commonly used； for soothing the liver and address both mental and physical health to calm wei qi， treatment should advocate verbal counseling， psychological regulation， and health education. Ultimately， this treatment approach can free liver qi to flow， soothe qi movement， restore the motion of wei qi， regulate during day and night， balance yin and yang， and resolve insomnia effectively.

Objective:To investigate the expression and clinical value of integrin-associated protein 47 (CD47) and soluble programmed death receptor-ligand 1 (sPD-L1) in patients with primary immune thrombocytopenia (ITP).Methods:The method of retrospective study was adopted, 76 patients with ITP admitted to the Affiliated Hospital of Jining Medical University from July 2016 to July 2022 were regarded as the study group, and another 76 cases of physical examination were regarded as the control group. The levels of serum CD47, sPD-L1, interleukin-33(IL-33) and transforming growth factor beta (TGF-β) were determined by the enzyme-linked immunosorbent assay, the diagnostic value of CD47 and sPD-L1 for ITP was analyzed by the receiver operating characteristic (ROC) curve, Pearson test was applied to analyze the correlation between serum CD47 and sPD-L1 in ITP patients, multivariate Logistic regression analysis was applied to analyze the risk factors affecting ITP.Results:The levels of serum CD47, sPD-L1 and IL-33 in the study group were higher than those in the control group: (40.31 ± 6.59) μg/L vs. (32.16 ± 6.33) μg/L, (78.42 ± 10.22) ng/L vs. (64.49 ± 10.36) ng/L, (73.29 ± 14.26) ng/L vs. (26.54 ± 5.16) ng/L; the level of serum TGF-β in the study group was lower than that in the control group: (1 752.66 ± 310.73) ng/L vs. (2 625.88 ± 389.58) ng/L, there were statistical differences ( P<0.05). The result of the Pearson test showed that there was a positive correlation between serum CD47 and sPD-L1 in ITP patients ( r = 0.572, P<0.05). The result of the ROC curve showed that the area under the curve predicted by the combination of serum CD47 and sPD-L1 was 0.948 (95% CI 0.916 - 0.979), which was better than that predicted by CD47 and sPD-L1 alone ( P<0.05). The result of multivariate Logistic regression analysis showed that CD47, sPD-L1, and IL-33 were the risk factors affecting ITP ( P<0.05), and TGF-β was the protective factor affecting ITP ( P<0.05). Conclusions:The serum levels of CD47 and sPD-L1 in patients with ITP are elevated, and the combined detection of the two indicators has a good diagnostic value for ITP.

Objective:To investigate the predictive value of platelet-to-albumin ratio (PAR) for organ failure in patients with acute pancreatitis (AP).Methods:The clinical data of 128 patients with AP from January 2021 to January 2024 in Affiliated Hospital of Jining Medical College were retrospectively analyzed. Among them, 68 patients developed organ failure (failure group), and 60 patients did not develop organ failure (non-failure group). The inflammatory indexes on admission were compared between the two groups. The severity of illness was evaluated by acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA). Pearson method was employed for correlation analysis.

Pearson correlation analysis result showed that PAR was positively correlated with APACHE Ⅱ, SOFA, white blood cell, platelet, red blood cell distribution width, C-reactive protein, fasting blood glucose, blood urea nitrogen and IL-6 ( r = 0.559, 0.623, 0.237, 0.782, 0.511, 0.392, 0.287, 0.555 and 0.505; P<0.01), and negatively correlated with serum calcium and albumin ( r = - 0.526 and - 0.820, P<0.01). ROC curve analysis result showed that the area under the curve of PAR for predicting organ failure in patients with AP was 0.875 (95% CI 0.818 to 0.933), with an optimal cutoff value of 4.56, sensitivity of 91.2%, and specificity of 66.7%. Conclusions:PAR can effectively predict the occurrence of organ failure in AP patients with high sensitivity, providing certain guiding significance for clinical treatment.

This paper reports a case of hepatoblastoma that is inclined to misdiagnosis and missed diagnosis. The patient, a 6-month-old male, was admitted to Dermatology Department of Children’s Hospital of Nanjing Medical University and Beijing Children’s Hospital successively, because of a erythema on the neck for 6 months and a mass in the neck for 3 months. Abdominal ultrasonography and CT indicated the possibility of hepatic hemangioma, but further examination of alpha fetoprote and other indicators suggested hepatic malignant tumor. Therefore, surgery was performed to remove the liver mass, and postoperative pathology revealed hepatoblastoma. Postoperative chemotherapy was combined, and follow-up was conducted six months after the end of chemotherapy, with no recurrence of the disease. This article summarized the diagnosis and treatment process of this case and combined with literature review to provide experience for clinicians in the diagnosis and treatment of relevant cases.

To investigate the prevalence of influenza D virus(IDV)in cattle and swine populations in Jilin Province,China,277 nasopharyngeal swabs were collected from livestock exhibiting influ-enza-like symptoms for IDV detection.Virus isolation was performed using swine testicular(ST)cells for PCR-positive samples,followed by comprehensive analyses including whole-genome se-quencing,phylogenetic analysis,electron microscopic observation of viral morphology,and glycosy-lation site prediction.Two IDV strains were successfully isolated from bovine samples,designated as D/bovine/China/JL22/2024(JL22)and D/bovine/China/JL34/2024(JL34).These strains were demonstrated to have specific hemagglutination activity against turkey red blood cells,while no he-magglutination to chicken,rabbit,or guinea pig erythrocytes.Virus-inoculated ST cells exhibited distinct cytopathic effects(CPE)within 48 h,with a hemagglutination titer of 4 log2 in the culture supernatant.Phylogenetic analysis of the hemagglutinin-esterase-fusion(HEF)gene indicated that these strains were most closely related to the Japanese isolate D/Yamagata2019,belonging to the YAMA2019 lineage.Genomic sequence analysis showed the absence of genetic reassortment in these isolates.In this study,two IDV strains were successfully isolated and characterized,which provides preliminary insights into their genomic sequences and biological properties.The findings confirm the presence of IDV in bovine populations in Jilin Province and provide the fundamental data for future epidemiological surveillance and control strategies of IDV.

YTHDF2 is a key m6A RNA modification"reader"that plays a crucial role in cell biological processes and tumor development.This review deeply explores the biological role of YTHDF2 and the advances in its application in tumors.The YTHDF2 structures are divided into mRNA procsomes and YTH domains,which recognize and bind m6A modified RNA molecules.It plays a biological role by promoting mRNA degradation,regu-lating cell signaling pathways and metabolism,and can regulate macrophage function and maintain an immunosup-pressive state in the tumor microenvironment.YTHDF2 has the potential to serve as diagnostic markers,therapeu-tic targets and prognostic evaluation biomarkers in different tumors,but currently relevant studies are insufficient in sample size,molecular mechanism and clinical application.In the future,research can be conducted on compre-hensive clinical research,in-depth analysis of molecular mechanisms,and research and development of optimized treatment strategies.

Tuberculosis is a zoonotic disease posing a substantial public health threat.Immunological diagnosis and vaccine im-munization are both necessary to control tuberculosis prevalence.However,the identical antigenic components in diagnostic reagents and vaccines hinder the use of animal vaccines and limit the specificity of clinical diagnosis in humans.Differentiating infected from vaccinated animals can overcome these problems.This article reviews the progress in differential diagnosis research from three as-pects:the diagnostic effects of antigens,methods for discovering new antigens,and screening of new host immune markers,to provide a theoretical basis for future research.
