α-Amino-3-hydroxyl-5-methyl-4-isoxazole propionic acid (AMPA) receptor, a subtype of ionotropic glutamate receptors widely distributed in the central nervous system, mediates the fast excitatory neurotransmission. Meanwhile more and more evidence indicates that AMPA receptor plays an important role in synaptic plasticity as well as central sensitization, and it also has close relationships with nervous system diseases. Over stimulation of AMPA receptor would produce excitotoxicity, leading to neuronal damage and finally resulting in a multitude of nervous system diseases, such as epilepsy, amyotrophic lateral scelerosis,Parkinson′s dis-ease. Competitive AMPA receptor antagonists that downregulate AMPA receptor′s function are of great importance in the prevention and treatment of nervous system diseases. This article reviews the research advances of competitive AMPA receptor antagonists.

Objective To explore the effects of deoxynivalenol (DON) on apoptosis of human gastric carcinoma cell line SNU in vitro. Methods SNU cells were treated with DON at different concentrations (50, 100, 1000, 2000 μg/L) for 12 hours, and then cells were harvested for cell apoptosis by flow cytometric (FCM) DNA analysis and the expression of Bax, Bcl-2 and Caspase-3 at protein level with FCM and Western blotting. Results FCM results showed that the apoptosis rates of SNU cells in DON treatment groups were all higher than that in control, especially in DON 1000 μg/L and 2000 μg/L groups (P<0.05). In the concentration range from 50 to 2000 μg/L, a significant concentration-depended response correlation could be found between apoptosis rate and DON concentration (r =0.940, P <0.01). FCM and Western blotting showed Bax and Caspase-3 expression in often SNU cells DON treatment for 12 hours were up-regulated while that of Bcl-2 was down-regulated. Conclusion DON can induce apoptosis of SNU cells in vitro in dose-dependent manner, and possible mechanisms of apoptosis induction effects may be up-regulation of the expression of Bax and down-regulation of that of Bcl-2 and activation of the key enzyme of apoptosis Caspase-3.

Objective:To analyze the relationship between antithrombin Ⅲ(AT-Ⅲ) activity and survival, bleeding and thrombosis complications in patients with acute-on-chronic liver failure (ACLF), and to explore the prediction value of AT-Ⅲ activity in the prognosis of ACLF patients.Methods:The clinical data of 130 hospitalized patients with ACLF were retrospectively collected in Wuxi No.5 People′s Hospital from January 1, 2013 to April 1, 2019. The liver function, international normalized ratio (INR), and 90-day survival rate were detected. The AT-Ⅲ activity values at admission, week two, week four, and week eight of hospitalization were recorded, and the occurrences of fecal occult blood and femoral vein thrombosis were also recorded. The measurement data were compared by t test, analysis of variance, or rank sum test, and the categorical data were compared by chi-square test. The risk factors affecting the survival of ACLF patients were analyzed by Cox regression. The survival analysis was performed using the Kaplan-Meier method. Results:At the end of 90-day follow-up of 130 patients, 56 patients died, 20 patients (15.38%) were fecal occult blood positive and 15 (11.54%) had femoral vein thrombosis. The baseline AT-Ⅲ activity in the death group was lower than that in the survival group ((17.89±13.68)% vs (36.03±11.96)%), and the difference was statistically significant ( t=-8.045, P<0.01). The baseline AT-Ⅲ activities in fecal occult blood positive and negative patients were (18.26±11.52)% and (25.06±10.97)%, respectively, and in femoral vein thrombosis and non-thrombotic patients were (17.55±10.33)% and (32.48±11.88)%, respectively. The differences were both statistically significant ( t=8.746 and 8.090, respectively, both P<0.01). Through dynamic monitoring of AT-Ⅲ, the AT-Ⅲ activity showed a downward trend in the death group, while that showed an upward trend in the survival group, but the differences were not statistically significant ( F=0.282 and 0.401, respectively, both P>0.05). The Cox regression analysis suggested INR (odds ratio ( OR)=1.364, 95% confidence interval ( CI) 1.078-1.726, P=0.010) and AT-Ⅲ activity ( OR=0.930, 95% CI 0.906-0.954, P<0.01) were the independent factors affecting the survival of patients with ACLF. The area under the receiver operator characteristic curve of the AT-Ⅲ activity for predicting 90-day survival outcome of the patient was 0.706 (95% CI 0.773-0.952, P<0.01), and the cut-off value was 25%. Patients with AT-Ⅲ activity ≥ 25% had a higher survival rate than those with AT-Ⅲ activity <25% ( χ2=58.20, P<0.01). Conclusions:AT-Ⅲ activity is associated with fecal occult blood positive and femoral vein thrombosis in ACLF patients. The AT-Ⅲ activity is an independent influencing factor for predicting the prognosis of ACLF patients. Patients with AT-Ⅲ activity less than 25% have the higher mortality rate.

Objective:To investigate the efficacy of postmastectomy radiotherapy (PMRT) for human epidermal growth factor receptor 2 (HER2)-positive T 1-2N 1M 0 breast cancer in the context of HER2-targeted therapy. Methods:This study collected the clinical data of 105 female patients with HER2-positive T 1-2N 1M 0 breast cancer who underwent modified radical mastectomy in the First Affiliated Hospital of Bengbu Medical College from January 2013 to December 2019. Then, the clinical outcomes of these patients were observed, and the prognostic factors and the efficacy of PMRT were analyzed. Results:The median follow-up time was 50 months (ranging from 14 to 107 months), and the 5-year overall survival (OS), local-regional recurrence-free survival(LRFS), and disease-free survival (DFS) were 81.6%, 91.9%, and 76.2%, respectively. The multivariate analysis indicated that independent prognostic factors for OS and DFS include the age, pathologic grade, and tumor size; the independent risk factors for LRFS include positive lymph node ratio (LNR) and hormone receptor (HR) status; and the independent prognostic factor for DFS was PMRT (HR: 2.85, 95% CI: 1.10-8.80, P < 0.05). The subgroup analysis suggested that PMRT significantly improved the OS of various high-risk subgroups ( χ2=4.01-9.18, P < 0.05). However, the further stratified analysis indicated that PMRT only increased the OS of the patients who did not receive HER2-targeted therapy in various high-risk subgroups ( χ2=4.50-6.70, P < 0.05), while there was no statistical difference before and after PMRT for the individuals who received targeted treatment ( P > 0.05). Conclusions:PMRT is an independent prognostic factor for the DFS of patients with HER2-positive T 1-2N 1M 0 breast cancer who underwent modified radical mastectomy. PMRT can improve the OS of high-risk patients with ages < 45 years old, pathologic grade Ⅲ, tumor diameter ≥ 3 cm, LNR > 10%, and HR (-) who received no HER2-targeted therapy. However, the efficacy may be compromised to some extent in the context of the application of HER2-targeted therapy.

Objective:To summarize the clinical characteristics in of different antibody subtypes in of patients with antisynthetase syndrome (ASS) complicated with interstitial lung disease (ILD).Methods:A retrospective analysis was conducted on 132 ASS-ILD patients at the First Affiliated Hospital of Nanjing Medical University (Jiangsu Provincial People′s Hospital), encompassing a period from December 2019 to June 2023. The data included were basic demographic information, clinical features, laboratory test results, chest computed tomography (CT) scans, and pulmonary lung function tests. Patients were categorized into distinct subtypes based on anti-aminoacyl tRNA synthetase (ARS) antibodies. Statistical analysis was performed using a t-test for comparing means between two samples with equal variance, the Mann-Whitney U test for non-normally distributed continuous data, and the chi-square ( χ2) test or Fisher′s exact test for categorical variables. Results:The most prevalent subtype of anti-synthetase antibody was anti-histidine antibody (Jo-1), accounting for 60 of 132 cases (45.5%), followed by anti-glycine-based tRNA synthetase antibody (EJ) (33/132, 2 5.0%), anti-tRNA synthase antibody (PL-7) (26/132, 19.7%), anti-alanine-based tRNA synthetase antibody (PL-12) (7.6%, 10/132), anti-isoleucine-tRNA synthase antibody (OJ) (3/132, 2.2%). The presence of anti-Ro-52 antibodies was significantly associated with rapidly progressive ILD. In patients with different subtypes of ASS-ILD, the presence of anti-Jo-1 antibodies is was positive in 28 cases (46.7%), and the combination of infection is was more common than in other groups ( χ2=0.15, P=0.047). The group with positive anti-EJ antibodies has had a significant decline in lung function, and cough is was more common in 31 cases (93.9%) than in other groups ( P<0.05); the group with positive anti-PL-12 antibodies has had a more pronounced decline in lung function than other groups ( P<0.05), and fever (7 cases, 70.0%) wais more common than in other groups ( χ2=0.02, P=0.022). Conclusion:Anti-Jo-1, Anti-PL-7, and Anti-PL-12 antibodies were are observed more frequently in patients with ILD. Furthermore, a significant deterioration in lung function was is observed in patients testing positive for anti-PL-12 and anti-EJ antibodies.

Objective:To explore the effects of the deep inspiration breath-hold (DIBH) technique on cardiac dosimetry in internal mammary node irradiation with intensity-modulated radiation therapy (IMN-IMRT) for postoperative left breast cancer.Methods:Totally 23 left breast cancer patients in the First Affiliated Hospital of Bengbu Medical College from Octorber 2021 to July 2022 receiving postoperative IMN-IMRT were enrolled in this study. The changes in dosimetric parameters for their heart and left anterior descending coronary artery (LAD) in the DIBH mode were observed, and the potential factors affecting DIBH effects were analyzed.Results:Compared with the free breath (FB) mode, the DIBH mode manifested a heart volume decrease by 18% ( t = 10.47, P < 0.001), a left lung volume increase by 42% ( t = -14.55, P < 0.001), and significantly reduced dosimetric parameters ( Dmean, Dmax, V5- V30) for the heart and LAD, exhibiting statistically significant differences ( t=-13.38 to -3.30, P<0.05). As indicated by the Pearson correlation analysis, the relative ratio of cardiac dose reduction was positively correlated with that of left lung expansion ( r = 0.82, P < 0.001) and negatively correlated with the patient′age ( r = -0.56, P = 0.005). Conclusions:DIBH can effectively reduce the heart and LAD radiation doses in IMN-IMRT for postoperative left breast cancer and that the patient's age, and the DIBH effects might be affected by the vital capacity.
