ObjectiveTo establish a mouse model of rheumatoid arthritis with interstitial lung disease (RA-ILD) in DBA/1 mice using Porphyromonas gingivalis (Pg) infection combined with collagen-induced arthritis (CIA), and to comprehensively evaluate pathological characteristics in joints, lungs, and serum. MethodsForty DBA/1 mice were randomly divided into four groups, i.e., Control, Pg infection (Pg), CIA, and Pg infection combined with CIA (Pg+CIA), with 10 mice in each group. Arthritis clinical symptoms were evaluated by recording arthritis incidence and clinical scores. Micro-CT scanning was used to assess knee joint pathology. Histopathological changes and collagen deposition in knee joints and lung tissues were analyzed using hematoxylin-eosin (HE) and Masson staining. Immunohistochemistry was performed to detect protein expression of α-smooth muscle actin (α-SMA), typeⅠ collagen (ColⅠ), and fibronectin (FN) in lung tissues. Real-time quantitative polymerase chain reaction(Real-time PCR)was used to measure mRNA expression levels of α-SMA, ColⅠ, FN, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-1β in lung tissues. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of Pg, cyclic citrullinated peptide (CCP), and immunoglobulin G (IgG). ResultsJoint lesions: The CIA and Pg+CIA groups showed 100% arthritis incidence, with evident joint redness, swelling, and deformity. The number of affected limbs was 27 and 28, and clinical scores were 68 and 70, respectively. No obvious clinical symptoms were observed in the Pg group. Histopathological and imaging analyses showed severe joint lesions in the CIA and Pg+CIA groups, with significantly increased histopathological scores, bone mineral density, bone volume fraction, trabecular thickness, and trabecular number compared to the Control group (P<0.01). No obvious joint pathology was observed in the Pg group. Lung lesions: The Pg+CIA group exhibited marked alveolar inflammation, interstitial inflammatory cell infiltration, and alveolar wall thickening, with pronounced blue staining of collagen fibers. Histopathological scores and collagen area ratios were significantly higher than those of the Control, Pg, and CIA groups (P<0.05). Lung protein and mRNA expression levels of α-SMA, ColⅠ, and FN were markedly increased, and mRNA levels of IL-6, TNF-α, and IL-1β were significantly elevated compared to the Control group (P<0.05). Serology: The Pg+CIA group showed significantly higher levels of CCP, Pg, and IgG compared with the Control, Pg, and CIA groups (P<0.05). ConclusionDBA/1 mice subjected to Pg infection combined with CIA exhibited pronounced symptoms and pathological features of RA-ILD, along with elevated serum anti-CCP antibody levels. This model represents a novel RA-ILD mouse model, providing a valuable experimental tool for investigating RA-ILD pathogenesis and developing new therapeutics, and serves as a basis for establishing anti-cyclic citrullinated peptide antibody (ACPA)-positive RA-ILD animal models.

Liver injury has become an increasingly serious global health problem, and existing chemical drugs face the limitations in efficacy and adverse reactions, resulting in the urgent need to develop safe and effective drugs. Recent studies have highlighted the potential of flavonoids from natural medicinal plants in the prevention and treatment of liver injury. As a typical natural flavonoid, luteolin shows a good protective effect against liver injury due to various etiologies, but there is still a lack of systematic elaboration on its mechanism of action. This article summarizes related research advances in China and globally and reviews the mechanism of action of luteolin in inhibiting oxidative stress, exerting an anti-inflammatory effect, regulating cell death, alleviating hepatic fibrosis, modulating lipid metabolism disorders, and regulating the gut-liver axis, as well as the application prospect of luteolin in the treatment of liver injury, in order to provide a scientific reference for further research on this compound.

ObjectiveTo observe the effect of functional pelvic floor muscle training on pelvic floor muscle function, incontinence symptoms and quality of life in female patients with stress urinary incontinence (SUI). MethodsFrom February, 2024 to July, 2025, 40 female patients with SUI were recruited from Beijing Bo'ai Hospital and advertisements. They were randomly divided into control group (n = 20) and experimental group (n = 20). The control group received conventional pelvic floor muscle contraction and relaxation training, and the experimental group received functional pelvic floor muscle contraction and relaxation training, for eight weeks. The data of pelvic floor muscle strength, pelvic floor muscle surface electromyography (sEMG), 1-hour urine pad test and Incontinence Quality of Life questionnaire (I-QOL) were collected before and after training. The compliance rate was counted after training. ResultsOne case dropped down in the control group and three cases dropped down in the experimental group. After treatment, the pelvic floor muscle strength increased in both groups (|Z| > 3.317, P < 0.01), the pre-resting average value, sustained contraction average value and durable contraction average value of sEMG improved in the control group (|t| > 2.731, P < 0.05), the mass of 1-hour urine pad significantly reduced (t > 9.215, P < 0.001) and the I-QOL score significantly increased (|t| > 13.229, P < 0.001) in both groups; compared with the control group, the pelvic floor muscle strength significantly increased (Z = -2.281, P = 0.023), the mass of 1-hour urine pad significantly reduced (t = 4.215, P < 0.001), the I-QOL score significantly increased (t = -4.501, P < 0.001), and the compliance rate significantly increased (Z = -2.798, P < 0.01) in the experimental group . ConclusionFunctional pelvic floor muscle training can significantly improve pelvic floor muscle strength, incontinence symptoms and quality of life in female patients with SUI.

ObjectiveTo investigate the difference in the risk of cardiovascular diseases between patients with different subtypes of non-alcoholic fatty liver disease (NAFLD) from the perspective of metabolism, since cardiovascular events induced by metabolic disorders are the leading cause of death in NAFLD. MethodsThe cluster sampling method was used to conduct a multicenter cross-sectional study among three representative hospitals in Pudong New Area of Shanghai, China. A total of 37 122 sets of physical examination data from July 2022 to June 2023 were collected and stratified according to body mass index (BMI). The chi-square test was used for comparison of continuous data between groups, and a multivariable Logistic regression analysis was used to investigate the association between NAFLD subtypes and cardiometabolic risk factors. ResultsA total of 9 372 cases of NAFLD were detected, with a detection rate of 25.25%, and more than 97% of these patients were diagnosed with metabolic associated fatty liver disease (MAFLD). The subgroup analysis showed that the detection rates of lean, overweight, and obese NAFLD were 7.72%, 33.99%, and 63.56%, respectively. Compared with the patients with lean or overweight NAFLD, the patients with obese NAFLD showed a significantly higher proportion of patients with abnormalities in blood pressure, blood glucose, triglyceride (TG), high-density lipoprotein (HDL) or uric acid (all P<0.001). Among related risk factors, lean NAFLD was associated with the increase in total cholesterol (TC)(P<0.05), while overweight NAFLD and obese NAFLD were not associated with TC abnormalities (P>0.05); obese NAFLD was not associated with TG abnormalities, while lean NAFLD and overweight NAFLD were associated with TG abnormalities (both P<0.05); all types of NAFLD were associated with the abnormalities of waist-hip ratio, blood pressure, blood glucose, low-density lipoprotein, HDL, and uric acid (all P<0.05). ConclusionThe detection rates of different subtypes of NAFLD in Shanghai Pudong are close to those reported in China and globally, and the epidemiologic data of NAFLD can be used analogously for MAFLD. There are certain differences in the distribution and association of cardiometabolic risk factors between different subtypes of NAFLD, and targeted interventions should be formulated based on the metabolic characteristics of each type of NAFLD.

AIM: To investigate timing of glucocorticoids use in the treatment of syphilitic uveitis.METHODS: A retrospective study was conducted in 110 patients(134 eyes)with syphilitic uveitis diagnosed from January 2008 to January 2021, of whom 24 were binocular. The time from onset to treatment was 1 d to 3 mo. They were divided into three groups according to the treatment, including 98 eyes with completed clearely fundus lesions and no abnormalities in fundus fluorescein angiography(FFA)+ indocyanine green angiography(ICGA)+ optical coherence tomography(OCT)after treated with antibiotics alone for 1 to 2 wk in single antibiotics group, 26 eyes with in completely cleared fundus lesions and retinal vessels wall staining observed by FFA or choroidal weak fluorescence observed by ICGA after standard antisyphilitic treatments for 1 to 2 wk in first antibiotics followed by hormones group, and 10 eyes treated according to uveitis at other hospital in the absence of a clear cause of disease, that was intravenously dripped with 250 mL of normal saline and 10 mg of dexamethasone once a day for 7 to 10 d in total, then clearly diagnosed as syphilitic uveitis by Treponema pallidum particle agglutination(TPPA)test after receiving treatment for 10 to 14 d in hormones followed by antibiotics group. The best corrected visual acuity, slit-lamp examination, fundus photography, OCT, FFA, ICGA and prognosis of the three groups of patients were compared.RESULTS: There were statistically significant difference in the best corrected visual acuity, optic disc, retinal vasculitis, choroidal weak fluorescence, and RPR titer before and after treatment of the three groups of patients. The prognosis of the hormones followed by antibiotics group was lower than that in the single antibiotics group and antibiotics followed by hormones group, and the proportion of “good” prognosis in the antibiotics followed by hormones group was larger than that in other groups.CONCLUSION: Early diagnosis and regular treatment of syphilitic uveitis has a good overall prognosis, and giving large doses of glucocorticoids before thorough antisyphilitic treatments is not conducive to the recovery of disease. In patients with residual lesions after standard antisyphilitic, the application of small doses of glucocorticoids is helpful for the recovery of the disease.

Neuropathic pain is frequently comorbidity with cognitive deficits. Neuralized1 (Neurl1)-mediated ubiquitination of CPEB3 in the hippocampus is critical in learning and memory. However, the role of Neurl1 in the cognitive impairment in neuropathic pain remains elusive. Herein, we found that lumbar 5 spinal nerve ligation (SNL) in male rat-induced neuropathic pain was followed by learning and memory deficits and LTP impairment in the hippocampus. The Neurl1 expression in the hippocampal CA1 was decreased after SNL. And this decrease paralleled the reduction of ubiquitinated-CPEB3 level and reduced production of GluA1 and GluA2. Overexpression of Neurl1 in the CA1 rescued cognitive deficits and LTP impairment, and reversed the reduction of ubiquitinated-CPEB3 level and the decrease of GluA1 and GluA2 production following SNL. Specific knockdown of Neurl1 or CPEB3 in bilateral hippocampal CA1 in naïve rats resulted in cognitive deficits and impairment of synaptic plasticity. The rescued cognitive function and synaptic plasticity by the treatment of overexpression of Neurl1 before SNL were counteracted by the knockdown of CPEB3 in the CA1. Collectively, the above results suggest that the downregulation of Neurl1 through reducing CPEB3 ubiquitination and, in turn, repressing GluA1 and GluA2 production and mediating synaptic plasticity impairment in hippocampal CA1 leads to the genesis of cognitive deficits in neuropathic pain.

Therapeutic cancer vaccines have experienced a resurgence over the past ten years. Cancer vaccines are typically designed to enhance specific stages of the cancer-immunity cycle, primarily by activating the immune system to promote tumor regression and overcome immune resistance. In this review, we summarize the significant recent advancements in cancer immunotherapy based on the cancer-immunity cycle, including the effector cell function, infiltration, initiation, and exhaustion. We summarize the identification of tumor antigens and their delivery through cancer vaccines. We discuss how specific stages of the cancer-immunity cycle have been leveraged to augment anti-tumor immune responses and improve vaccine efficacy. Additionally, the impact of aging and myelosuppression, two prevalent forms of immunological stress, on the effectiveness of therapeutic cancer vaccines is deliberated. Finally, we summarize the current status of various therapeutic cancer vaccines at different clinical trial phases.

Background Occupational disease diagnosis appraisal is an appeal procedure initiated when a party disagrees with the occupational disease diagnosis conclusion. It is a legal procedure to safeguard the health rights of employees and the legitimate rights and interests of employers. Objective To analyze the data of occupational disease diagnosis appraisal in Shanghai, identify existing problems, and provide suggestions for improving. Methods Statistical analysis was conducted on basic situation, characteristics of workers and employers, disease classification, and consistency between diagnosis and appraisal conclusions of all occupational disease diagnosis appraisal cases from 2012 to 2024. All diagnosis conclusions were named in accordance with the Classified Catalogue of Occupational Diseases included employers were classified according to the Measures for the Statistical Classification of Large, Medium, Small and Micro Enterprises" and the Notice on Adjusting the Provisions for Classifying Enterprise Registration Types; industry classification followed the Industrial Classification for National Economic Activities (GB/T 4754-2017). Results From 2012 to 2024, a total of 260 cases of occupational diseases diagnosis appraisal were closed. The main diagnosis were 138 cases of ear, nose, throat, and oral diseases (53.1%), chemical poisoning (18.8%), and pneumoconiosis and other respiratory diseases (16.2%). The proportion of ear, nose, throat, and oral diseases gradually increased (2022 excluded). The incidence of annual municipal and provincial cases decreased by 76.3% and 85.0% respectively (2024 vs 2012). The consistency rate of conclusions between appraisal and diagnosis gradually increased. The total consistency rates between final appraisals and diagnostic conclusions were 81.5%, and 79.7%, 87.8%, 100.0%, 85.0% for ear, nose, throat, and oral diseases, chemical poisoning, and pneumoconiosis and other respiratory system diseases, respectively. Specifically, the consistency rates were 80.1% and 80.0% for noise-induced deafness and chronic benzene poisoning. In terms of inconsistency reasons, "inconsistent interpretation of standards and excessive discretion in standard application" accounted for 43.8%, followed by "failure to correctly apply standards" (31.3%) and and "discrepancies in occupational exposure history recognition" (15.6%). Conclusion The revisions and improvements of the legal system for occupational disease diagnosis appraisal have played a positive role in improving the consistency of conclusions between appraisal and diagnosis of occupational diseases in Shanghai. It is suggested to further strengthening the publicity and training of occupational disease diagnosis standards to improve the quality of occupational disease diagnosis.
