BackgroundSchizophrenia is a highly heterogeneous disease with different clinical subtypes. Artificial intelligence technology represented by deep learning models has provided considerable benefits for the electroencephalogram (EEG)-based schizophrenia diagnosis, treatment and research, however, to date little research has been conducted regarding any of these benefits among Chinese schizophrenic patients. ObjectiveTo investigate the application of deep learning techniques utilizing EEG parameters for the diagnosis of first-episode schizophrenia and grading of EEG abnormalities in patients, with the aim of contributing to improved clinical diagnosis and treatment strategies for the disorder. MethodsFrom January 2020 to January 2023, a total of 130 patients with first-episode schizophrenia who met the diagnostic criteria of International Classification of Diseases, tenth edition (ICD-10), and attended at the Third People's Hospital of Fuyang, along with 150 health checkup examinees, were enrolled. All of them underwent EEG examination. An optimized long short-term memory (LSTM) deep learning model was developed utilizing EEG signals. Ten-fold cross-validation method was employed to evaluate the model's performance. The dataset was then split into two components: a training set (90%) for LSTM model development and a test set (10%) for validation. The accuracy, recall rate, precision, F1-score, schizophrenia diagnosis and EEG abnormality grading were used as evaluation indicators, and the results of the proposed model were compared to the assessments made by experienced psychiatrists. ResultsFor schizophrenia diagnosis, the modeling group achieved the following performance metrics: precision (94.40±3.03)%, recall rate (94.30±3.23)%, accuracy (94.60±2.22)%, and F1-score (94.20±2.20)%. In the validation group, the corresponding metrics were precision (90.90±2.85)%, recall rate (92.20±1.14)%, accuracy (92.20±1.69)%, and F1-score (91.50±1.78)%. Statistical analysis revealed no significant differences between the LSTM diagnostic model and the experienced psychiatrists in terms of precision, recall rate, accuracy, and F1-score for schizophrenia diagnosis (χ2=1.500, 0.750, 2.722, 1.056, P>0.05). The modeling group demonstrated an accuracy rate of (91.71±1.73)% in grading EEG abnormalities. For Grade 1 abnormalities, the modeling group reported a precision of (96.40±2.39)%, a recall rate of (94.77±1.40)%, and an F1-score of (95.55±1.14)%. In the case of Grade 2 abnormalities, the precision was (85.89±2.04)%, the recall rate was (88.10±6.18)%, and the F1-score was (87.06±3.12)%. For the more severe Grade 3 abnormalities, the modeling group's precision was (79.61±7.33)%, the recall rate was (81.79±9.87)%, and the F1-score was (80.41±6.79)%. Additionally, the validation group exhibited an accuracy rate of (85.61±6.16)%. The precision, recall rate, and F1-score for Grade 1 abnormalities were (91.43±6.25)%, (92.64±9.65)% and (91.56±4.83)%, respectively. For Grade 2 abnormalities, these metrics were (71.17±19.02)%, (77.64±17.24)% and (71.88±11.33)%. In the case of Grade 3 abnormalities, the precision was (90.00±21.08)%, the recall rate was (80.00±25.82)%, and the F1-score was (81.67±19.95)%. There was no significant difference in the accuracy, recall, accuracy and F1 value between LSTM model and senior doctors in evaluating the abnormal degree of EEG in schizophrenia (χ2=0.098, 0.036, 0.020, 0.336, P>0.05). The LSTM model takes less time to diagnose schizophrenia and EEG abnormalities than senior doctors, and the differences were statistically significant (t=57.147, 43.104, P<0.01). ConclusionThe study utilizes an EEG-based LSTM deep learning model for diagnosing first-episode schizophrenia and grading EEG abnormalities, and the model not only matches the performance of experienced psychiatrists but also significantly reduces the time required for diagnosis.

The Baihe Dihuang Decoction(BDD) is a representative traditional Chinese medicine formula that has been used to treat depression. This study employed metabolomics and network pharmacology to investigate the mechanism of BDD in the treatment of depression. Fifty male Sprague-Dawley(SD) rats were randomly assigned to the normal control group, model group, fluoxetine group, and high-and low-dose BDD groups. A rat model of depression was established through chronic unpredictable mild stress(CUMS), and the behavioral changes were detected by forced swimming test and open field test. Metabolomics technology was used to analyze the metabolic profiles of serum and hippocampal tissue to screen differential metabolites and related metabolic pathways. Additionally, network pharmacology and molecular docking techniques were used to investigate the key targets and core active ingredients of BDD in improving metabolic abnormalities of depression. A "component-target-metabolite-pathway" regulatory network was constructed. BDD could significantly improve depressive-like behavior in CUMS rats and regulate 12 differential metabolites in serum and 27 differential metabolites in the hippocampus, involving tryptophan metabolism, phenylalanine, tyrosine, and tryptophan biosynthesis, alanine, aspartate, and glutamate metabolism, tyrosine metabolism, and purine metabolism. Verbascoside, isorbascoside, and regaloside B were the key active ingredients for improving metabolic abnormalities in depression. Epidermal growth factor receptor(EGFR), protooncogene tyrosine-protein kinase(SRC), glycogen synthase kinase 3β(GSK3β), and androgen receptor(AR) were the key core targets for improving metabolic abnormalities of depression. This study offered a preliminary insight into the mechanism of BDD in alleviating metabolic abnormalities of depression through network regulation, providing valuable guidance for its clinical use and subsequent research.

BACKGROUND:
This study aimed to investigate programmed death-ligand 1 tumor proportion score in predicting the safety and efficacy of PD-1/PD-L1 antibody-based therapy in treating patients with advanced non-small cell lung cancer (NSCLC) in a real-world setting.
METHODS:
This retrospective, multicenter, observational study enrolled adult patients who received PD-1/PD-L1 antibody-based therapy in China and met the following criteria: (1) had pathologically confirmed, unresectable stage III-IV NSCLC; (2) had a baseline PD-L1 tumor proportion score (TPS); and (3) had confirmed efficacy evaluation results after PD-1/PD-L1 treatment. Logistic regression, Kaplan-Meier analysis, and Cox regression were used to assess the progression-free survival (PFS), overall survival (OS), and immune-related adverse events (irAEs) as appropriate.
RESULTS:
A total of 409 patients, 65.0% ( n = 266) with a positive PD-L1 TPS (≥1%) and 32.8% ( n = 134) with PD-L1 TPS ≥50%, were included in this study. Cox regression confirmed that patients with a PD-L1 TPS ≥1% had significantly improved PFS (hazard ratio [HR] 0.747, 95% confidence interval [CI] 0.573-0.975, P = 0.032). A total of 160 (39.1%) patients experienced 206 irAEs, and 27 (6.6%) patients experienced 31 grade 3-5 irAEs. The organs most frequently associated with irAEs were the skin (52/409, 12.7%), thyroid (40/409, 9.8%), and lung (34/409, 8.3%). Multivariate logistic regression revealed that a PD-L1 TPS ≥1% (odds ratio [OR] 1.713, 95% CI 1.054-2.784, P = 0.030) was an independent risk factor for irAEs. Other risk factors for irAEs included pretreatment absolute lymphocyte count >2.5 × 10 9 /L (OR 3.772, 95% CI 1.377-10.329, P = 0.010) and pretreatment absolute eosinophil count >0.2 × 10 9 /L (OR 2.006, 95% CI 1.219-3.302, P = 0.006). Moreover, patients who developed irAEs demonstrated improved PFS (13.7 months vs. 8.4 months, P <0.001) and OS (28.0 months vs. 18.0 months, P = 0.007) compared with patients without irAEs.
CONCLUSIONS
A positive PD-L1 TPS (≥1%) was associated with improved PFS and an increased risk of irAEs in a real-world setting. The onset of irAEs was associated with improved PFS and OS in patients with advanced NSCLC receiving PD-1/PD-L1-based therapy.
