Objective To explore the relationship between the polymorphism of excision repair cross-complementation group 1 (ERCC1) C8092A locus and the efficacy and prognosis of platinum-based chemotherapy for lung cancer (LC), and to provide a theoretical basis for precision treatment of LC. Methods From January 2014 to October 2017, 120 patients from two tertiary hospitals in Haikou City, and with pathologically confirmed lung cancer treated with platinum-based chemotherapy were selected as the research objects. After informed consent was obtained, peripheral blood samples were collected for DNA extraction, and the genotype of ERCC1 C8092A locus was detected by mass spectrometry. WHO's Response Evaluation Criteria in Solid Tumours (RECIST) was used to judge patients' chemotherapy efficacy and patients' survival status was obtained by telephone follow-up and other means. Results Among the 120 LC patients, the genotype frequencies of ERCC1 C8092A locus were 67 cases of CC wildtype (55.8%), 45 cases of CA heterozygous type (37.5%), and 8 cases of AA rare mutation type (6.7%), which conformed to Hardy-Weinberg equilibrium (χ2=0.140, P>0.05). The total effective rate of chemotherapy was 32.5%, with the highest effective rate in patients with the CA genotype (42.2%) at the ERCC1 C8092A locus and the lowest in patients with the CC genotype (25.4%). The overall one-year survival rate was 68.3% and the three-year survival rate was 35.8%. The patients with ERCC1 C8092A AA genotype had the lowest survival rate, with a one-year survival rate of 50.0% and three-year survival rate of only 25.0%. However, there were no statistical differences in the overall survival rate among the three genotypes of carriers of ERCC1 C8092A (χ2=0.328, P=0.849). Conclusions The polymorphism of ERCC1 C8092A locus is associated with the efficacy of platinum-based chemotherapy for LC, and patients with CA genotype have the highest efficacy. The one-year and three-year survival rates of patients with CC genotype are significantly higher than those of CA and AA genotypes.

Objective:
To explore the neuroprotective effects of the Shaoyao Gancao decoction (SGD) against excitatory damage in PC12 cells and the role of the Src-NR2-nNOS pathway mediation by SGD in regulating γ-aminobutyric acid (GABA)-glutamate (Glu) homeostasis.
Methods:
N-Methyl-d-aspartic acid (NMDA) was used to establish a PC12 cell excitability injury model. To investigate the neuroprotective effect of SGD, a cell counting kit-8 (CCK-8) assay was used to determine PC12 cell viability, Annexin V/Propidium Iodide (Annexin V/PI) double staining was used to determine PC12 cell apoptosis, and Ca2+ concentration was observed using laser confocal microscopy. GABA receptor agonists and antagonists were used to analyze the neuroprotective interactions between γ-aminobutyric acid (GABA) and NMDA receptors. Additionally, molecular biology techniques were used to determine mRNA and protein expression in the Src-NR2-nNOS pathway. We analyzed the correlations between the regulatory sites of GABA and NMDA interactions, excitatory neurotoxicity, and brain damage at the molecular level.
Results:
NMDA excitotoxic injury manifested as a significant decrease in cell activity, increased apoptosis and caspase-3 protein expression, and a significant increase in intracellular Ca2+ concentration. Administration of SGD, a GABAA receptor agonist (muscimol), or a GABAB receptor agonist (baclofen) decreased intracellular Ca2+ concentrations, attenuated apoptosis, and reversed NMDA-induced upregulation of caspase-3, Src, NMDAR2A, NMDAR2B, and nNOS. Unexpectedly, a GABAA receptor antagonist (bicuculline) and a GABAB receptor antagonist (saclofen) failed to significantly increase excitatory neurotoxicity.
Conclusions
Taken together, these results not only provide an experimental basis for SGD administration in the clinical treatment of central nervous system injury diseases, but also suggest that the Src-NR2A-nNOS pathway may be a valuable target in excitotoxicity treatment.

Objective:To establish a scoring system for preoperative prediction of the malignant potential of gastric stromal tumors based on gastroscopic and endoscopic ultrasound features, along with validation.Methods:A total of 286 patients who were treated in Jiangsu Province Hospital of Chinese Medicine from January 1, 2017 to December 31, 2023 and diagnosed as having gastric stromal tumors by postoperative pathology were enrolled in the modeling group. According to National Institutes of Health classification system, 227 very-low/low-risk patients were classified into the low malignant potential (LMP) group, and the 59 intermediate/high-risk patients into the high malignant potential (HMP) group. LASSO regression analysis was performed to identify predictive factors for HMP gastric stromal tumors, and a nomogram prediction model was developed. Internal validation using the Bootstrap method was performed on the modeling group, and external validation was performed on data from 85 patients who were treated and diagnosed as having gastric stromal tumors by postoperative pathology in Taizhou People's Hospital from January 1, 2021 to December 31, 2023. The receiver operator characteristic (ROC) curves, calibration curves, and decision curve analyses were employed in both the modeling and external validation groups.Results:Tumor size (coef=0.755), tumor shape (coef=0.015), tumor location (coef=0.008), growth pattern (coef=-0.026), cystic change (coef=0.685), and surface unceration change (coef=-0.545) were the independent predictive factors for HMP gastric stromal tumors. The nomogram-based prediction model constructed using these factors achieved an area under the ROC curve of 0.959 (95% CI: 0.898-0.903) in the modeling group and 0.959 (95% CI: 0.857-1.000) in the external validation group. The model demonstrated good accuracy (0.917) and a Kappa value of 0.737 in internal validation. Calibration curve and decision curve analyses indicated strong calibration and high net benefit in both the modeling and the external validation groups. Conclusion:Tumor size, tumor shape, tumor location, growth pattern, cystic change, and surface ulceration change are independent predictive factors for HMP gastric stromal tumors. The nomogram model developed based on these factors offers effective and convenient visualization for clinicians to predict the malignant potential of gastric stromal tumors preoperatively.
