Objective:To summarize and analyze the clinical characteristics of systemic lupus erythematosus (SLE) combined with ischaemic stroke and the factors associated with poor prognosis.Methods:A total of 50 patients with SLE combined with ischaemic stroke in the First Affiliated Hospital of Xi′an Jiaotong University from January 2014 to June 2024 were included in the study, the clinical data of the patients were retrospectively collected and summarized, the Shapiro-Wilk test was used to assess the normality of data, and the factors related to poor prognosis were analyzed by logistic regression analyses.Results:Fifty patients with SLE combined with ischaemic stroke had a mean age of (47.1±15.5)years, 80.0%(40/50) were female, the duration of SLE was (5.6±6.3)years, the mean SLEDAI-2K score was (14.3±4.1), the rate of anticardiolipin antibody positivity was 30.0%(15/50), and the rate of β 2-glycoprotein Ⅰ antibody positivity was 28.0%(14/50). The most common clinical manifestations of stroke were impaired limb movement (34.0%) (17/50), cerebral infarction mainly in the cerebral hemisphere (82.0%)(41/50), combined with cerebral haemorrhage in 6.0%(3/50), cerebral leukoencephalopathy in 26.0%(13/50), and cerebral atrophy in 24.0%(12/50). In terms of treatment, the most used immunosuppressant was cyclophosphamide (34.0%, 17/50), 64.0%(32/50) of patients received aspirin, 32.0%(16/50) received clopidogrel and 14.0%(7/50) received anticoagulation. Four deaths and 12 cases of severe disability were found in 50 patients at follow-up, and SLEDAI-2000 scores were positively correlated with the above poor prognosis using univariate [ OR(95% CI)=1.407(1.123,1.764), P=0.003] and multivariate [ OR(95% CI)=1.388(1.097, 1.756), P=0.006] regression analyses. Conclusion:Patients with SLE combined with ischaemic stroke had high disease activity in SLE, and SLEDAI-2000 scores were positively associated with poor prognosis of death and severe disability.

Objective:To investigate the impact of the interval between neoadjuvant immunotherapy combined with chemotherapy(nICT) and surgery on pathological outcomes and prognosis in patients.Methods:This is a retrospective cohort study. A total of 115 patients with locally advanced esophageal squamous cell carcinoma who underwent nICT followed by sequential surgery at Department of Thoracic Surgery, Peking University People′s Hospital or Department of Thoracic Surgery, the First Affiliated Hospital of Zhengzhou University from January 2020 to April 2024 were included. Among them, 99 were male and 16 were female, with an age of ( M(IQR)) 65 (11) years (range:45 to 81 years). All patients received 2 to 6 cycles of paclitaxel plus platinum-based doublet chemotherapy combined with PD-1 immune checkpoint inhibitors. The resectability of tumors was assessed based on CT scans of the chest and abdomen, and surgical approaches included Sweet surgery, Mckeown surgery, and Ivor-Lewis surgery. Patients were divided into a short-interval group (4 to <6 weeks) and a long-interval group (6 to 12 weeks) based on the interval between neoadjuvant immunochemotherapy and surgery. General patient data, surgical details, pathological response, and prognosis were collected and analyzed. Data comparisons were performed using independent sample t-test, Mann-Whitney U test, χ 2 test, or Fisher′s exact test. Multivariate logistic regression analysis was used to identify independent factors influencing pathological complete response (pCR). Survival analysis was conducted using the Kaplan-Meier method and Log-rank test. Results:There were no significant differences in baseline characteristics, neoadjuvant treatment details, surgical outcomes, or postoperative complications between the long-interval group and the short-interval group (all P>0.05). Multivariate Logistic regression analysis revealed that, among clinical factors, interval between neoadjuvant immunochemotherapy and surgery was significantly associated with pCR (long-interval group vs. short-interval group: OR=4.14, 95% CI:1.63 to 10.50, P=0.003). The pCR rate was higher in the long-interval group (43.6% vs. 17.1%, χ2=6.48, P=0.011). Survival analysis showed no significant differences in overall survival ( P=0.094) or disease-free survival ( P=0.840) between the two groups. Conclusion:Appropriately extending the surgical interval after neoadjuvant immunochemotherapy maybe lead to a higher pCR rate, without increasing surgical difficulty or damaging prognosis.

Objective To explore the mechanism of Shanggan granules in suppressing pulmonary inflammation in mice infected with H1N1 influenza virus.Methods A mouse model of pulmonary influenza virus infection was established by nasal inoculation with H1N1 influenza virus.Mice were divided into a normal control group,model group,positive control group,and low-,medium-,and high-dose Shanggan granules groups.Mice were treated for 7 days and then sacrificed,and the body weight and lung wet weight were measured.Pathological changes in the lung tissues were detected by hematoxylin/eosin(HE)staining.Tumor necrosis factor-α(TNF-α),interleukin(IL)-6,IL-8,and transforming growth factor-β(TGF-β)levels in lung tissues were detected by enzyme-linked immunosorbent assay,and superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),and malondialdehyde(MDA)were detected using appropriate kits.Toll-like receptor 4(TLR4)/nuclear factor-κB(NF-κB)inflammatory signaling pathways were detected by real-time polymerase chain reaction,and TANK-binding kinase 1(TBK1)/interferon regulatory factor(IRF)signaling pathway proteins were detected by Western blot.Results Both Shanggan granules and oseltamivir phosphate reduced the lung wet weight(P＜0.05,P＜0.001)in mice infected with influenza virus H1N1 compared with the model group,decreased the infiltration of inflammatory cells in lung tissue,reduced levels of the inflammatory factors TNF-α,IL-6,IL-8,and TGF-β(P＜0.05,P＜0.01,P＜0.001),decreased levels of SOD and GSH-Px in lung tissue(P＜0.05,P＜0.01),and increased MDA levels(P＜0.05,P＜0.01).Shanggan granules and oseltamivir phosphate also reduced TLR4,MyD88,and p38 mRNA levels(P＜0.05,P＜0.01)and expression of TBK1/IRF3/7/NF-κB signaling pathway proteins(P＜0.05,P＜0.01,P＜0.001).Conclusions Shanggan granules may effectively reduce lung injury,lung inflammation,and oxidative stress,via a mechanism related to the down-regulation of TLR4/NF-κB inflammatory signaling pathways.

Parkinson′s disease (PD) is a neurodegenerative disorder primarily characterized by motor dysfunctions, yet it currently lacks a "gold standard" for clinical diagnosis and staging. This poses significant challenges for early diagnosis with accuracy and the objective assessment of disease severity. In recent years, the study of biological markers in PD has gained increasing attention. At the International Congress of PD and Movement Disorders in 2023, 2 biomarker-based diagnostic frameworks were proposed: SynNeurGe and NSD-ISS. The SynNeurGe framework emphasizes classification by integrating α-synuclein (α-syn, S), neurodegeneration (N) and genetic variants (G), while the NSD-ISS framework focuses on redefinition and staging, centering on neuronal α-syn pathology. Despite their different target populations and focuses, both frameworks reflect a clear trend toward biomarker-driven and objective approaches in PD diagnosis. Current research priorities include validating the reproducibility and improving the accessibility of biomarker detection methods and developing in vivo neuroimaging techniques for α-syn aggregation, aiming to facilitate disease-modifying therapy for PD.
