Objective This study aims to investigate the effects of FGL2 on the immune response of EBV-infected T cells,including their activation,proliferation,exhaustion,and cytokine profile changes.Methods Primary T cells were infected with EBV at different multiplicities of infection(MOI).Expression of FGL2 in T cells,as well as T-cell activation,proliferation,exhaustion,and cytokine levels,were detected using RT-qPCR,Western blot,ELISA,CCK8,and flow cytometry(FCM),respectively.Further experiments involving FGL2 knockdown and overexpression were conducted to elucidate its specific regulatory role in EBV-infected T cells.Results FGL2 expression was significantly upregulated in EBV-infected T cells(P<0.05).EBV infection also induced enhanced T cell activation(P<0.001),proliferation(P<0.001),and exhaustion(P<0.01).Compared to the T cells+EBV group,the T cells+EBV+FGL2 overexpression group exhibited higher exhaustion levels(P<0.01),reduced activation(P<0.05)and proliferation(P<0.05),decreased pro-inflammatory cytokine levels(P<0.05),and increased anti-inflammatory cytokine levels(P<0.05).Conversely,the T cells+EBV+FGL2 knockdown group demonstrated the opposite trends,with elevated activation(P<0.01),proliferation(P<0.05),pro-inflammatory cytokine levels(P<0.05),and reduced exhaustion(P<0.01)and anti-inflammatory cytokine levels(P<0.05).Conclusion FGL2 suppresses T cell activation and proliferation,exacerbates T cell exhaustion,inhibits pro-inflammatory cytokine release,and promotes anti-inflammatory cytokine secretion during EBV infection,thereby modulating the immune response of T cells.

Objective:To evaluate the efficacy and safety of therapeutic temperature control in patients with severe traumatic brain injury (sTBI).Methods:The full-text databases of Chinese Medical Journal, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP Database, China Biomedical Database, PubMed, Embase, and Cochrane Library were searched for randomized controlled trials (RCTs) of hypothermia treatment and conventional treatment in patients with sTBI. The search period was from January 2016 to June 2025. Meta-analysis was performed using RevMan 5.3 software. The evaluation indicators included intracranial pressure before treatment, at 3 and 5 days after treatment, favorable prognosis rate and mortality rate within 6 months after treatment, and incidence of pulmonary infection, intracranial infection, epilepsy, acute gastrointestinal dysfunction, deep vein thrombosis, abnormal coagulation function, and arrhythmia during treatment; publication bias.Results:A total of 33 studies involving 3 322 patients were included, with 1 696 patients in the temperature treatment group and 1 626 in the conventional treatment group. There was no statistically significant difference in intracranial pressure between the two groups before treatment ( SMD=0, 95% CI -0.13, 0.14, P>0.05). However, at 3 and 5 days after treatment, the intracranial pressure was lower in the temperature treatment group than that in the conventional treatment group ( SMD=-2.29, 95% CI -2.76, -1.82, P<0.01; SMD=-2.66, 95% CI -3.43, -1.89, P<0.01). Within 6 months after treatment, the favorable prognosis rate was higher in the temperature treatment group than that in the conventional treatment group ( RR=1.41, 95% CI 1.32, 1.50, P<0.01), and mortality rate was lower than that in the conventional treatment group ( RR=0.64, 95% CI 0.55, 0.75, P<0.01). Compared with the conventional treatment group, the incidences of epilepsy and acute gastrointestinal dysfunction in the temperature treatment group were statistically reduced ( RR=0.33, 95% CI 0.13, 0.83, P<0.05; RR=0.43, 95% CI 0.25, 0.74, P<0.05). There were no statistically significant differences in the incidence of pulmonary infection ( RR=0.96, 95% CI 0.85, 1.08, P>0.05), intracranial infection ( RR=0.56, 95% CI 0.20, 1.56, P>0.05), deep vein thrombosis ( RR=0.93, 95% CI 0.69, 1.25, P>0.05), abnormal coagulation function ( RR=1.19, 95% CI 0.43, 3.31, P>0.05) or arrhythmia ( RR=0.51, 95% CI 0.23, 1.12, P>0.05) between the two groups. Egger′s test indicated the presence of publication bias and the results remained robust after trim and fill analysis. Conclusions:For patients with sTBI, temperature control therapy shows lowered intracranial pressure and mortality rate as well as improved favorable prognosis rate at 6 months posttreatment, and decreased incidence of epilepsy and acute gastrointestinal dysfunction during treatment, while reveals similar incidence of pulmonary infection, intracranial infection, deep vein thrombosis, abnormal coagulation function, and arrhythmia when compared with conventional treatment.

Ileocecal duplication is a rare congenital gastrointestinal abnormality,with lesions predominantly localized near the ileocecal valve and manifesting as cystic structures.Clinically,it presents with diverse symptoms,including abdominal pain,vomiting,abdominal mass,etc.However,symptoms such as intussusception and appendicitis are easily confused with it.Furthermore,the imaging features of ileocecal duplication are nonspecific,which further increases the risk of misdiagnosis.Treatment options include laparoscopic surgery and laparotomy.Notably,laparoscopic surgery is highly feasible,especially for infants and young children,and achieves a prognosis comparable to that of laparotomy.In the case report presented in this study,a 1-year-old male patient was admitted to the hospital due to abdominal pain.Definitive diagnosis could not be established through comprehensive imaging examinations,and the diagnosis of ileocecal duplication cyst was ultimately confirmed surgically.Additionally,the diagnosis,imaging features,treatment,and prognosis of ileocecal duplication are systematically collated and summarized.

Objective:To investigate the efficacy and safety of a combination of programmed death receptor 1 (PD-1) inhibitor and multi-target tyrosine kinase inhibitor anlotinib in second-line treatment of non-small cell lung cancer (NSCLC).Methods:A prospective randomized controlled study was conducted. Using the random number table method, 118 NSCLC patients who were admitted to Shaanxi Provincial Cancer Hospital from June 2021 to June 2023 were randomly divided into the control group and the observation group, with 59 patients in each group. The observation group was treated with PD-1 inhibitor combined with anlotinib, while the control group was treated with PD-1 inhibitor. There were 36 males and 23 females in the observation group, with an age of (56±5) years; there were 34 males and 25 females in the control group, with an age of (56±5) years. There was no statistically significant difference in general clinicopathological data between the two groups (all P > 0.05). The short-term clinical efficacy [objective response rate (ORR) and disease control rate (DCR)], tumor-related factor levels [vascular endothelial growth factor (VEGF), matrix metalloproteinase 2 (MMP-2), tissue inhibitor of matrix metalloproteinase (TIMP), and tumor necrosis factor β1 (TNF-β1)], inflammatory status [plasma fibrinogen-to-albumin ratio (FAR)], lung function [forced vital capacity (FVC) and peak expiratory flow (PEF)] before and after treatment, the European Organization for Research and Treatment on Cancer (EORTC) core questionnaire for quality of life assessment (QLQ-C30) score, and occurrence of adverse reactions were compared between two groups of patients. Results:The ORR and DCR of the observation group were 33.90% (20/59) and 69.49% (41/59), respectively; the ORR and DCR of the control group were 10.17% (6/59) and 44.07% (26/59), respectively; the comparison of ORR and DCR between the two groups showed statistically significant differences ( χ2 values were 9.67 and 7.77, both P < 0.05). There was no statistically significant difference in the levels of tumor-related factors between the observation group and the control group before treatment (all P > 0.05); after 4 cycles of treatment, the levels of VEGF and MMP-2 in the observation group were lower than those in the control group, while the levels of TIMP and TNF-β1 were higher than those in the control group, and the differences were statistically significant (all P < 0.001). The FAR of the observation group and the control group before treatment were (0.15±0.06) g/L and (0.16±0.06) g/L, respectively, with no statistically significant difference ( t = 0.90, P = 0.367); after 4 cycles of treatment, the FAR were (0.07±0.01) g/L and (0.11±0.04) g/L, respectively, with statistically significant difference ( t = 7.45, P < 0.001). Before treatment, there was no statistically significant difference in FVC and PEF between the observation group and the control group (both P > 0.05); after 4 cycles of treatment, the FVC and PEF in the observation group were higher than those in the control group, and the differences were statistically significant (both P < 0.001). There were no statistically significant differences in the EORTC QLQ-C30 scores of functional dimension, symptom dimension and global health status/quality of life dimension between the observation group and the control group before treatment (all P > 0.05); after 4 cycles of treatment, the scores of functional dimension and global health status/quality of life dimension in the observation group were higher than those in the control group, while the symptom dimension score was lower than that in the control group, and the differences were statistically significant (all P < 0.001). The incidence of adverse reactions in the observation group was 6.78% (4/59), while in the control group it was 10.17% (6/59), and the difference was not statistically significant ( P = 0.741). Conclusions:The combination of PD-1 inhibitor and anlotinib in second-line treatment of NSCLC has good clinical efficacy, it can reduce the inflammatory response, improve the lung function and quality of life, and has good safety.
