This study aimed to investigate the molecular mechanism by which astrocyte elevated gene 1 protein (AEG-1) upregulates the transcriptional expression of eukaryotic translation initiation factor 4E (eIF4E) and its role in the sensitivity of gastric cancer cells to cisplatin (CDDP). Transcriptomic and correlation analyses based on The Cancer Genome Atlas (TCGA) database were performed to screen potential transcriptional regulatory mechanisms of AEG-1. In gastric cancer cell lines, plasmid overexpression, siRNA interference, and pharmacological inhibition were applied, combined with luciferase reporter assay, qRT-PCR, and Western blot to detect the transcriptional and expression changes of eIF4E. Co-immunoprecipitation (Co-IP) was used to verify the interaction between AEG-1 and E1A binding protein p300 (p300), as well as their binding changes upon CXC chemokine ligand 12 (CXCL12) stimulation. Sulforhodamine B colorimetric assay and flow cytometry were employed to evaluate CDDP sensitivity and apoptosis levels, respectively. The transcriptomic and database analyses suggested that AEG-1 may regulate eIF4E expression through acetylation-related mechanisms, and that EP300 was positively correlated with both MTDH and EIF4E in gastric cancer tissues. Functional experiments confirmed that AEG-1 upregulated the transcriptional expression of eIF4E in a p300-dependent manner, and that phosphorylation of AEG-1 at the site of serine 426 (S426) inhibited this effect. CXCL12 stimulation enhanced the protein-protein interaction between AEG-1 and p300. In addition, AEG-1 reduced the sensitivity of gastric cancer cells to CDDP, whereas phosphorylated AEG-1 enhanced cellular sensitivity to CDDP. In conclusion, AEG-1 enhances eIF4E transcriptional expression in a p300-dependent manner, and the phosphorylation status of AEG-1 at the S426 site serves as a key regulatory switch. The AEG-1/p300/eIF4E axis modulates CDDP chemotherapy sensitivity in gastric cancer, providing a new theoretical basis and potential intervention target for precision therapy of gastric cancer.

Objective:To evaluate preoperative high-resolution thin-layer cervical enhanced CT used to predict the venous route of the submental flap reflux vein and its relationship with adjacent structures in order to guide the anatomical understanding and protection of submental flap in pharyngeal cancer surgery.Methods:Sixty consecutive patients with pharyngeal cancer who underwent submental flap repair surgery in our department from March 2022 to December 2024, as well as 60 patients who were accepted neck dissection suffering other cancers, were selected. Before surgery, high-resolution cervical enhanced CT scans were performed, and the position of the transverse section of the facial vein in the venous phase horizontal image gradually variation tendency was focused layer by layer. The direction and adjacent relationship of the submental flap reflux veins were determined and recorded. Combined with 60 patients with other head and neck tumors who underwent neck dissection in our department during the same period (a total of 120 cases, 240 sides), the classification and management of the draining veins of Fang′s mental flap were conducted. Type Ⅰ mainly drains into the internal jugular vein; Type Ⅱ mainly drains into the external jugular vein and Type Ⅲ mainly drains into the anterior jugular vein (often accompanied by an external jugular draining branch). The status and proportion of venous drainage were analyzed.Results:Vascular predictive coincidence rate was 98.3% (59/60) among the 60 patients with pharyngeal cancer. Only one patient was predicted to have a simple return to the external jugular vein. However, during the operation, in addition to the main return to the external jugular vein, a small portion also returned to the internal jugular vein. Submental flap reflux vessels were classified into three types based on intraoperative submental flap venous return in 60 cases of laryngopharyngeal cancer, in conjunction with the analysis of venous return patterns from 240 cervical CT scans. Type Ⅰ mainly refluxed to the internal jugular vein, accounting for 42.1%. Type Ⅱ mainly refluxed to the external jugular vein (47.9%). Type Ⅲ mainly refluxed to the anterior jugular vein (10.0%). The total detection rate of CT reading of 240 venous reflux was 98.7% (237/240). Vascular predictive coincidence rate was 97.9%(235/240).Conclusion:The detailed analysis of submental venous return vessels can accurately predict the direction of reflux veins and its surrounding areas by preoperative high-resolution enhanced CT scan. This provides reliable guidance for the anatomy and protection of the submental flap reflux veins during surgery.

Objective: To investigate the treatment outcomes and risk factors of postoperative recurrence in T4a papillary thyroid carcinoma (PTC). Methods: A total of 185 patients with locally advanced T4a PTC treated in Beijing Tongren Hospital, Capital Medical University from January 2006 to December 2019 were retrospectively analyzed, including 127 females and 58 males, aged between 18 and 80 years, with 74 patients aged over 55 years. According to AJCC thyroid tumor staging, 111 cases were stage I (T4aN0M0 26 cases, T4aN1aM0 35 cases, and T4aN1bM0 50 cases) and 74 cases were stage Ⅲ (T4aN0M0 29 cases, T4aN1aM0 19 cases, and T4aN1bM0 26 cases). Kaplan-Meier method was used to calculate the overall survival and the recurrence-free rate, and univariate and multivariate logistic regression analyses on the clinical data were performed. Results: Recurrent laryngeal nerve invasion was observed in 150 cases, trachea invasion in 61 cases, esophagus invasion in 30 cases, and laryngeal structure invasion in 10 cases. Postoperative follow-up periods were 24-144 months, with an average of 68.29 months. Of the 185 patients, 18 (9.73%) had recurrences or metastases, including 9 cases (4.86%) died of recurrences or metastases. The 5-year and 10-year overall survival rates were respectively 95.21% and 93.10%. The 5-year and 10-year disease-free survival rates were respectively 89.65% and 86.85%. Univariate analysis showed that age of onset, tumor diameter, preoperative recurrent laryngeal nerve palsy, esophageal invasion and cervical lymph node metastasis were the risk factors for postoperative recurrence of T4a PTC(all P<0.05). Multivariate analysis showed that preoperative recurrent laryngeal nerve palsy (OR=3.27, 95%CI: 1.11-9.61, P=0.032) and lateral cervical lymph node metastasis (OR=4.71, 95%CI: 1.19-18.71, P=0.027) were independent risk factors for T4a PTC recurrence. Survival rate of patients with T4a PTC involving only the recurrent laryngeal nerve or the outer tracheal membrane was significantly better than that of patients with tracheal invasion (P<0.05). Conclusions: T4a PTC patients with R0 resection can still achieve good efficacy. Preoperative recurrent laryngeal nerve palsy and lateral cervical lymph node metastasis are independent risk factor for postoperative recurrence in the patients.

Pneumonia caused by SARS-CoV-2 has seriously threatened human life and health worldwide and caused a large number of deaths. Viral infection and acute inflammation are important causes of death, so it is particularly important to combine antiviral therapy with anti-inflammatory therapy. Glycyrrhizic acid, the main component of the glycyrrhizic root extract, has a wide range of pharmacological effects as well as high efficiency and low toxicity, its preparation has been widely used in the treatment of chronic hepatitis and other diseases. Glycyrrhizic acid can regulate the expression and release of a variety of cytokines and play a significant anti-inflammatory effect. At the same time, glycyrrhizic acid also showed significant inhibition towards a variety types of viruses. Therefore, the potential application of glycyrrhizic acid as COVID-19 treatment should be explored.

Objective:To compare the efficacy of traditional open thyroidectomy and modified Miccoli in the treatment of benign thyroid diseases.Methods:The data of 343 patients with benign thyroid disease in Xi′an Central Hospital and Xi′an Third Hospital were retrospectively analyzed. According to the surgical method, the patients were divided into the observation group (modified Miccoli operation, n=169) and the control group (traditional open operation, n=174). The operation effect, postoperative recovery, patient satisfaction, postoperative complications and recurrence within 1 year of follow-up were compared between the two groups.Count data were represented by n(%), measurement data consistent with normal distribution were represented by Mean± SD, and non-normal data were represented by M( P25, P75). T test or Wilcoxon rank sum test were used to compare the measurement data between groups according to their distribution characteristics. Comparison of statistical data between groups was made by chi-square test. Results:The intraoperative blood loss and postoperative drainage volume of the patients in the observation group were 26.2 (6.9, 40.8) ml and (33.4±8.6) ml, respectively, which were significantly less than those in the control group 50.6 (37.5, 63.7) ml and (35.7±9.5) ml (all P<0.05). The postoperative recovery time in the observation group was (3.9±2.8) d, which was significantly shorter than that in the control group (5.1±2.4) d ( P=0.001). Postoperative complications such as hoarseness, subcutaneous ecchymosis, scar formation and decreased parathyroid function were significantly different between the two groups ( P<0.05). The recurrence rate of 7.69% in the observation group was significantly lower than that of 19.54% in the control group 12 months after operation ( P<0.05). Conclusions:The modified Miccoli in the treatment of benign thyroid diseases not only has the advantages of less trauma, faster postoperative recovery, less pain and higher patient satisfaction, but also has lower postoperative complications and recurrence rate, which is worthy of clinical promotion and application.

Objective:To explore the diagnosis and treatment of focal segmental glomerulosclerosis (FSGS) post-kidney transplantation in children.Methods:Clinical data were retrospectively analyzed for 6 FSGS children after transplantation from 2015 to 2019. Massive proteinuria (3.2-13 g/24 h) occurred at 4 days-49 days post-transplantation. For proteinuria, glucocorticoid plus therapeutic plasma exchange and/or rituximab were provided with supplemental ACEI/ARB drugs. Five cases received tacrolimus as maintenance therapy while another case had cyclosporin A as an initial intensive therapy and switched to tacrolimus.Results:Four cases achieved complete remission after therapy. One recipient showed partial remission. During a follow up period of 11 months to 4 years, serum creatinine remained normal and stable in five cases while one died from severe pulmonary infection.Conclusions:Once FSGS occurs post-transplantation, prompt treatment of pulse glucocorticoid plus therapeutic plasma exchange and/or rituximab with supplemental ACEI/ARB drugs may yield favorable outcomes.
