BackgroundThe mental health issues of medical staff have received increasing attention. Previous studies have mainly focused on the epidemiological characteristics and influencing factors， but there is a lack of sufficient understanding of the heterogeneity characteristics of the depression-anxiety symptoms network among medical staff. ObjectiveTo compare the differences in the depression-anxiety symptoms network between medical staff and community residents， so as to provide references for the promotion of the mental health of medical staff. MethodsFrom June 1， 2022 to December 31， 2024， a stratified random sampling method was used to recruit 1 959 medical staff from public hospitals and community health centers in 9 townships （industrial parks） of Dongguan City， Guangdong Province， as well as 2 412 community residents in this area， were selected as the research subjects. The general situation questionnaire， Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， and the Generalized Anxiety Disorder Scale-7 item （GAD-7） were used for investigation. The network visualization was conducted using the qgraph package of R 4.0.0. The centrality indicators of the network were calculated using the networktools package. The reliability of the network structure was evaluated using the bootnet package. The differences in the depression-anxiety symptoms network between medical staff and community residents were compared using the NetworkComparisionTest package. ResultsA total of 1 792 medical staff and 2 110 community residents completed the survey. The numbers of medical staff with mild， moderate and severe depressive symptoms were 381 （21.26%）， 217 （12.11%） and 169 （9.43%）， respectively， while the numbers of community residents were 322 （15.26%）， 98 （4.64%） and 66 （3.13%）， respectively. The numbers of medical staff with mild， moderate and severe anxiety symptoms were 411 （22.94%）， 126 （7.03%） and 93 （5.19%）， respectively， while the numbers of community residents were 320 （15.17%）， 73 （3.46%） and 18 （0.85%）， respectively. The comparison of the detection rates of depressive symptoms and anxiety symptoms between the two groups showed statistically significant differences （χ²=152.012， 205.953， P<0.01）. The network analysis results showed that the core symptom clusters of medical staff were "uncontrollable worry" "psychomotor retardation" "inability to relax"， and "depression"， while those of community residents were "uncontrollable worry" "inability to relax" "inferiority complex"， and "depression". There was a statistically significant difference in the network structure between the two groups （M=0.275， P<0.05）， and the overall connection strength of medical staff was lower than that of community residents （7.523 vs. 7.950， S=0.426， P<0.05）. ConclusionThe detection rates of depression and anxiety symptoms among medical staff were higher than those among community residents. The depression-anxiety symptoms network of medical staff was more concentrated， and the core symptoms were more prominent.［Funded by Social Development and Technology Project of Dongguan City （number， 20221800902552）］

Background Polycyclic aromatic hydrocarbons represented by benzo[a]pyrene are among the most significant occupational and environmental pollutants. Exposure to benzo[a]pyrene during pregnancy can cause delayed intellectual development in offspring, and the mechanism may be related to the expression of protocadherin (Pcdh), a key molecule for learning and memory. Objective To explore the possible role of Pcdh in impaired learning and memory function of pups caused by benzo[a]pyrene exposure during pregnancy by establishing an animal model of cognitive impairment in pups caused by benzo[a]pyrene exposure during pregnancy, and detecting the expression of Pcdh and its transcription-related factors in the hippocampal tissues of pups at different developmental stages. Methods Sixty female and male SPF-grade rats were caged in a 1:1 ratio overnight, and the successfully mated female mice were randomly divided into blank control, 0 mg·kg⁻¹, 10 mg·kg⁻¹, 20 mg·kg⁻¹, and 40 mg·kg⁻¹ groups, with 6 mice in each group. They were intraperitoneally injected with benzo[a]pyrene from the 17th to the 19th day of pregnancy to establish an exposure model. Learning and memory functions of the offspring were tested through Morris water maze on the 45th day after the birth (PND) of the pups. On the PND45 and PND75 of the pups, hippocampal tissues of 6 pups (per group) were collected respectively. The expression levels of PcdhαC1 and wings apart-like homolog (WAPL) genes and proteins were detected by fluorescence quantitative polymerase chain reaction (PCR) and Western blotting. Results The results of Morris water maze showed that there was no interaction between the escape latency time of the pups and the dose groups of 0 mg·kg⁻¹, 10 mg·kg⁻¹, 20 mg·kg⁻¹, and 40 mg·kg⁻¹ (F _{time × group}=0.515, P>0.05). The escape latency of pups decreased with increase of training time (F _time=24.678, P<0.001, F _group=12.803, P<0.001). The PCR results showed that at PND45, compared with the blank group, the relative expression levels of PcdhαC1 mRNA in the 10 mg·kg⁻¹, 20 mg·kg⁻¹, and 40 mg·kg⁻¹ groups decreased (P<0.05), and the relative expression levels of WAPL mRNA increased (P<0.05). At PND75, compared with the blank group, the relative expression levels of PcdhαC1 mRNA in the 20 mg·kg⁻¹ and 40 mg·kg⁻¹ groups decreased (P<0.05), and the relative expression levels of WAPL mRNA increased (P<0.05). The Western blotting results showed that at PND45, compared with the blank group, the expression levels of PcdhαC1 protein in the 10 mg·kg⁻¹, 20 mg·kg⁻¹, and 40 mg·kg⁻¹ groups decreased (P<0.05), and the expression levels of WAPL protein increased (P<0.05). At PND75, compared with the blank group, the expression levels of PcdhαC1 protein in the 10 mg·kg⁻¹, 20 mg·kg⁻¹, and 40 mg·kg⁻¹ groups decreased (P<0.05), and the expression levels of WAPL protein increased (P<0.05). Conclusion Exposure to benzo[a]pyrene during pregnancy can cause impairment in the learning and memory abilities of PND45 offspring and may alter the expression of PcdhαC1 and WAPL genes and proteins.

Acute liver failure (ALF) is a life-threatening condition associated with macrophage-mediated inflammatory responses. Effective therapies and drugs are still lacking to date. Here, we reveal that a derivative of xanthohumol, CAM12203, alleviates lipopolysaccharide (LPS) + d-galactosamine (D-GalN)-induced ALF through limiting macrophage-mediated inflammation, with the most significant impact on interleukin-1β (IL-1β) transcription. Through biotin labeling-mediated pull-down and LC-MS/MS analysis, diacylglycerol kinase ζ (DGKζ), a lipid-metabolizing kinase, is identified as the direct target of CAM12203. Mechanistically, DGKζ is induced in macrophages upon inflammatory stimuli and is upregulated observed on clinical liver failure samples. Its product phosphatidic acid (PA) boosts phospholipase C (PLC)-inositol 1,4,5-trisphosphate (IP₃)-Ca²⁺ signaling and subsequent janus kinase 2 (JAK2)-signal transducer and activator of transcription 3 (STAT3) cascade, ultimately promoting IL-1β production and liver failure. DGKζ knockdown/ablation or inhibition significantly impairs the DGKζ-STAT3-IL-1β pathway along with ALF progression. Finally, CAM12203 is confirmed to be a new DGKζ inhibitor and acts against inflammation in a DGKζ-reliant manner. Taken together, CAM12203 inhibits IL-1β transcription in macrophages by binding to DGKζ and blocking the DGKζ-STAT3 axis, thereby exerting an ameliorative effect on ALF. These results not only highlight CAM12203 as a promising lead compound for ALF treatment, but also define DGKζ as a novel therapeutic target.

Inflammation represents a critical immune response triggered by cellular activities and inflammatory mediators following tissue damage. It plays a central role in the pathological progression of diverse diseases, including psychiatric disorders, cancer, and immunological conditions, rendering it an essential target for therapeutic intervention. Periodontitis, a prevalent oral inflammatory disease, is a leading cause of tooth loss and poses significant health challenges globally. Traditionally, inflammatory diseases such as periodontitis have been treated with systemic administration of synthetic chemicals. However, recent years have witnessed challenges, including drug resistance and microbial dysbiosis associated with these treatments. In contrast, natural products derived from Chinese medicine offer numerous benefits, such as high safety profiles, minimal side effects, innovative pharmacological mechanisms, ease of extraction, and multiple targets, rendering them viable alternatives to conventional antibiotics for treating inflammatory conditions. Numerous effective anti-inflammatory natural products have been identified in traditional Chinese medicine (TCM), including alkaloids, flavonoids, terpenoids, lignans, and other natural products that exhibit inhibitory effects on inflammation and are potential therapeutic agents. Several studies have confirmed the substantial anti-inflammatory and immunomodulatory properties of these compounds. This comprehensive review examines the literature on the anti-inflammatory effects of TCM-derived natural products from databases such as PubMed, Web of Science, and CNKI, focusing on terms like "inflammation", "periodontitis", "pharmacology", and "traditional Chinese medicine". The analysis systematically summarizes the molecular pharmacology, chemical composition, and biological activities of these compounds in inflammatory responses, alongside their mechanisms of action. This research seeks to deepen understanding of the mechanisms and biological activities of herbal extracts in managing inflammatory diseases, potentially leading to the development of promising new anti-inflammatory drug candidates. Future applications could extend to the treatment of various inflammatory conditions, including periodontitis.

OBJECTIVES: This study aims to explore the current status and risk factors of oral health-related quality of life OHRQoL in patients with mental disorders and provide evidence for effective intervention measures. METHODS: A total of 397 patients diagnosed with mental illness were selected by convenience sampling, and investigation was carried out using general data questionnaire, health literacy in dentistry-14 (HeLD-14), oral health impact profile-14 (OHIP-14), and oral health status checklist. RESULTS: The total score of OHIP-14 in patients with mental disorders was 8(2, 14). The score of HeLD-14 was negatively correlated with the score of OHIP-14 (r=-0.142, P<0.01). The results of multiple linear regression showed that six variables including annual family income, schizophrenia, sweets, frequency of visits to the dentist, dental caries, and missing teeth affected OHRQoL of patients with mental disorders (P<0.05). CONCLUSIONS The poor OHRQoL of psychiatric patients is associated with many factors. Medical personnel should pay attention to their oral health problems and develop targeted oral care programs throughout the course of disease to improve oral health and related quality of life of patients.

Objective:To investigate disease characteristics of patients with psoriatic arthritis (PsA) based on the PsA cohort in West China Hospital, so as to provide a reference for clinicians in its diagnosis, treatment, and evaluation strategy formulation.Methods:A cross-sectional study was carried out, and a descriptive analysis was conducted on clinical data from PsA patients who were treated at the Department of Dermatology, West China Hospital, Sichuan University between April 2, 2020, and January 21, 2025. Demographic characteristics, clinical manifestations, laboratory and imaging findings, and treatment modalities were analyzed.Results:A total of 530 PsA patients were included, of whom 332 (62.6%) were males and 198 (37.4%) were females, with ages of 44.1 ± 12.4 years. Skin lesions preceded joint symptoms in 452 patients (85.3%), with time intervals ( M [ Q1, Q3]) of 8.0 (3.0, 15.0) years. Overweight or obesity was observed in 319 patients (60.2%), and 188 (35.5%) had comorbid fatty liver. Peripheral joint involvement was common (485 cases, 91.5%), with the proximal interphalangeal joints being most frequently affected by tenderness (172 cases, 35.5%) and swelling (119 cases, 24.5%) ; the number of enthesitis cases identified by ultrasonography (116 cases, 23.9%) was significantly higher than that by clinical examination (82 cases, 15.5%) ; axial joint involvement was observed in 258 patients (48.7%), with the sacroiliac joints most commonly affected (201 cases, 77.9%). Regarding treatment, conventional systemic drugs were predominant in the treatment of psoriasis prior to the diagnosis of PsA; after the diagnosis of PsA, the number of patients receiving targeted therapies increased to 334 (63.0%), with interleukin-17 inhibitors being the most common (140 cases, 26.4%), followed by tumor necrosis factor-α inhibitors (106 cases, 20.0%) and Janus kinase inhibitors (39 cases, 7.4%) . Conclusions:PsA predominantly affects males over 40 years old and is characterized by preceding skin lesions, delayed diagnosis, and multiple comorbidities. High-frequency ultrasound has advantages in the early detection of peripheral enthesitis. Further attention is needed for managing comorbidities such as fatty liver and obesity-related metabolic conditions.

This study aims to evaluate the preventive effect of the exogenous protein chIFN-γ-chCD154 against Salmonella typhimurium(S.typhimurium)infection in White Leghorn chick-ens,and the potential mechanism.In this study,Escherichia coli was used to express the proteins chIFN-γ,chCD154 and chIFN-γ-chCD154.Before S.typhimurium infection,the White Leghorn chickens were pre-immunized via drinking water for three consecutive days,and infected with S.typhimurium by gavage.The results from Western blot,quantitative real-time PCR(qRT-PCR)analysis and histopathology analysis showed that compared to chIFN-γ and chCD154,chIFN-γ-chCD154 pre-treatment could synergistically increase the survival rate of infected chickens,reduce the bacterial load in the liver and cecum,and attenuate the pathological damage of liver and cecum.Moreover,chIFN-γ-chCD154 significantly decreased the mRNA expression of Toll-like receptor-4(TLR-4)and myeloid differentiation primary response gene 88(MyD88)in the cecum,and then inhibited the mRNA expression of NF-κB and pro-inflammatory cytokines(TNF-α and IL-6),and maintained the integrity of the intestinal tight junction proteins(zo-1,claudin-1,occlu-din).Compared with single protein pretreatment,chIFN-γ-chCD154 pretreatment significantly up-regulated the mRNA expression of the genes related to the vitamin D(VD)pathway(cyp27b1,VD receptor VDR,antimicrobial peptide AvBD7 and cathelicidin-b1)in S.typhimurium-infected peripheral blood mononuclear cells(PBMCs).The results of colony counting showed that the num-ber of S.typhimurium in the chIFN-γ-chCD154 group were the lowest.Also,chIFN-γ-chCD154 could up-regulate the relative abundance of beneficial bacteria such as Blautia,Ruminococcus,En-terococcus and Faecalibacterium,while down-regulate the relative abundance of harmful bacteria such as Staphylococcaceae in the cecum and improve the intestinal dysbiosis.In conclusion,chIFN-γ-chCD154 could activate the VD-antimicrobial peptide pathway and inhibit the TLR-4/MyD88/NF-κB inflammatory signaling pathway in S.typhimurium-infected chickens,which significantly improve the intestinal barrier function,reduce the inflammatory damage of liver and cecum,im-prove the structure of cecum microbial,promote the health of intestinal tract,and provide theoreti-cal basis for the development of chIFN-γ-chCD154 as a safe and effective alternative antibiotic.

Objective:To evaluate the efficacy and safety of anlotinib neoadjuvant therapy for newly diagnosed locally advanced thyroid cancer (LATC).Methods:Twenty-four newly diagnosed LATC patients (10 males and 14 females, age (47.1±3.3) years) admitted to Affiliated Hospital of Integrated Traditional Chinese and Western Medicine of Nanjing University of Chinese Medicine were prospectively included from January 2023 to April 2024. Patients were given anlotinib neoadjuvant therapy (12mg/d, 2 weeks of medication, 1 week of discontinuation), and the efficacy of the treatment was evaluated by CT and multi-disciplinary treatment at the end of each treatment cycle. Patients assessed as suitable for surgery would be scheduled for surgery, while those who were not suitable for surgery would continue to receive neoadjuvant therapy and periodic evaluations. The primary endpoints were objective response rate (ORR) and disease control rate (DCR), and the R0/1 resection rate and adverse events (AE) after neoadjuvant therapy were observed. Paired- t test was used to analyze the differences between groups, and the Clopper-Person accurate method was used to calculate the bilateral 95% CI of ORR and other indicators. Results:Twenty-four patients received 2(2, 3) cycles of neoadjuvant therapy with anlotinib, of which 23 underwent surgery after anlotinib therapy. After neoadjuvant therapy, the mean maximum diameter of target lesions decreased by 23.5%(95% CI: 2.8%-44.3%) compared with baseline ( t=9.22, P<0.001). The ORR and DCR were 37.5%(95% CI: 18.8%-59.4%) and 100%(95% CI: 85.8%-100%), respectively. About 91.7%(95% CI: 73.0%-99.0%) of patients eventually underwent R0/1 resection. Hand and foot skin reactions, hypertension, oral mucositis, and leukopenia were common AE; grade 4 and 5 AE were not observed. Conclusion:Anlotinib can be safely used as neoadjuvant therapy for newly diagnosed LATC patients with good antitumor effects, providing better surgical opportunities for R0/1 resection.
