ObjectiveThis study aims to identify cuproptosis-related gene biomarkers in Alzheimer's disease(AD) using bioinformatics and machine learning methods, validate them at the clinical specimen level, and predict potential traditional Chinese medicine(TCM). MethodsDifferentially expressed genes in the AD group and normal group were obtained using the Gene Expression Omnibus (GEO) database, and intersections were taken with reported cuproptosis-related genes to obtain differentially expressed cuproptosis-related genes. Machine learning methods were applied to identify core differential genes of cuproptosis in AD. Peripheral blood's single nucleated cells from clinical AD patients were collected, and the relative gene expression was clinically verified by real-time polymerase chain reaction(Real-time PCR). Potential TCM regulating cuproptosis for AD were predicted by COREMINE database. ResultsA total of 12 cuproptosis-related genes were obtained, mainly involved in pathways of tricarboxylic acid cycle, 2-oxocarboxylic acid metabolism, and carbon metabolism. Five core cuproptosis-related genes, dihydrolipoamide dehydrogenase (DLD), glutaminase (GLS), pyruvate dehydrogenase E1 subunit beta (PDHB), full name nuclear factor (erythroid-derived 2)-related factor 2 (NFE2L2), and dihydrolipoamide branched-chain transacylase E2 (DBT) were finally screened using four machine methods. Thirty cases each of normal and AD patients were collected clinically. Compared with those in the normal group, minimum mental state examination (MMSE) and Montreal cognitive assessment (MoCA) were significantly decreased in the AD group (P<0.01), Homocysteine(Hcy), interleukin(IL)-6, C-reactive protein(CRP) , and β amyloid protein(Aβ) indexes were significantly increased (P<0.01), and malondialdehyde(MDA) indexes were decreased (P<0.05). Superoxide dismutase(SOD) levels were significantly decreased (P<0.01). The mRNA relative expressions of NFE2L2 and DBT were up-regulated (P<0.05), and those of DLD, GLS, and PDHB were significantly down-regulated (P<0.01). The TCM regulating cuproptosis-related genes for the treatment of AD were mainly based on the four Qi such as warmth, calmness, and cold, and the five flavors including bitterness, sweetness, and pungency, and it was attributed to the meridians of the liver, spleen, stomach, and kidney, with the efficacy of tonifying Qi, activating blood, eliminating phlegm, and resoling dampness. ConclusionDLD, GLS, NFE2L2, PDHB, and DBT can be used as novel diagnostic molecular markers for AD cuproptosis-related genes, and the corresponding potential therapeutic TCM can provide new ideas for the treatment of AD by TCM.

Objective:To explore the clinical manifestations, diagnosis, treatment, pathological types and prognosis of primary cervical neuroblastoma in children. Methods:The clinical data of 11 children with primary cervical neuroblastoma admitted to the Department of Otolaryngology and Head and Neck Surgery at Shanghai Children's Hospital from April 2015 to April 2022 were retrospectively analyzed. The clinical characteristics, imaging findings, pathological types, treatment methods, and outcomes of these 11 patients were examined in conjunction with a review of the literature. Results:The cohort of 11 neuroblastoma patients ranged in age from 28 days to 88 months (median age: 24 months), including 3 males and 8 females. Among the 11 patients, 4 had tumors located in the carotid sheath area, 4 in the cervical space, and 3 in the parapharyngeal and retropharyngeal spaces. The clinical manifestations primarily included painless cervical masses and laryngeal stridor. There were 3 cases of primary cervical tumors with cervical lymph node metastasis and 1 case with bone marrow metastasis. Pathological findings revealed neuroblastoma in 8 cases and ganglionic neuroblastoma in 3 cases. In this group, 7 patients underwent surgery combined with chemotherapy, 2 patients received surgery combined with chemoradiotherapy, and 2 patients underwent surgery alone. Surgical resection was performed via a cervical approach in 7 cases, while 3 cases were treated using a transoral endoscopic approach. Additionally, one patient underwent a transoral endoscopic approach initially and a cervical approach subsequently. All patients completed their treatment and were followed up regularly, with follow-up durations ranging from 6 to 79 months (median: 34 months). Nine patients achieved complete remission, 2 patients achieved partial remission, and none experienced disease progression. Conclusion:Primary cervical neuroblastoma exhibits a high degree of heterogeneity and presents at a younger age, primarily with cervical masses. Compared to external approaches, endoscopy-assisted transoral resection of parapharyngeal tumors offers advantages such as reduced damage to surrounding tissue and no visible neck scars, providing a new method for clinical treatment. Regular follow-up is essential for children with neuroblastoma, along with the establishment of specific disease management protocols and comprehensive care to improve survival quality.

OBJECTIVES:
To explore the mechanism of Gandou Fumu Decoction (GDFMD) for improving Wilson's disease (WD) in tx-J mice.
METHODS:
With 6 syngeneic wild-type mice as the control group, 30 tx-J mice were randomized into WD model group, low-, medium- and high-dose GDFMD treatment groups, and Fer-1 treatment group. Saline (in control and model groups) and GDFMD (3.48, 6.96 or 13.92 g/kg) were administered by gavage, and Fer-1 was injected intraperitoneally once daily for 14 days. Oil red and HE staining were used to observe lipid deposition and pathological conditions in the liver tissue; ALT, AST, albumin, AKP levels were determined to assess liver function of the mice. Western blotting and RT-qPCR were used to detect hepatic protein and mRNA expressions of GPX4, ACSL4, ALOX15, FTH1, FLT, TFR1, FAS, SCD1, and ACOX1, and Fe2+, MDA, ROS, SOD, GSH and 4-HNE levels were analyzed to assess oxidative stress.
RESULTS:
The mouse models of WD showed obvious fatty degeneration in the liver tissue significantly increased serum levels of ALT, AST and AKP, decreased albumin level, increased Fe2+, MDA, ROS, 4-HNE levels, decreased SOD and GSH levels (P<0.05), lowered protein expressions of ACOX1, GPX4, FTH1, FLT, FAS, and SCD1, and increased protein contents of TFR1, ACSL4 and ALOX15 in the liver. Treatment with GDFMD and Fer-1 improved liver histopathology and liver function of the mouse models, decreased the levels of Fe2+, MDA and ROS, increased SOD and GSH levels, and reversed the changes in hepatic protein expressions.
CONCLUSIONS
GDFMD improves liver steatosis in mouse models of WD possibly by inhibiting hepatocyte ferroptosis through the GPX4/ACSL4/ALOX15 signaling pathway.

OBJECTIVE To explore the effects and mechanism of atorvastatin on the proliferation, autophagy and glucose metabolism of AGS cells in human gastric cancer. METHODS The effects of low, medium and high concentrations of atorvastatin (12.5, 25, 50 μmol/L) on the viability of AGS cells were investigated through preliminary experiments, and the concentration of action was screened. The formal experiment was divided into control group (no intervention), atorvastatin group (25 μmol/L), positive control group (50 mg/L 5-fluorouracil), inhibitor group [25 μmol/L atorvastatin +10 μmol/L phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt) signaling pathway inhibitor LY294002] and activator group (25 μmol/L atorvastatin +10 μmol/L PI3K/Akt signaling pathway activator SC79), all of which were treated for 24 h. Glucose metabolism (glucose and lactic acid contents) and cell proliferation rate were detected, as well as the expression of autophagy-associated protein light chain 3 (LC3) Ⅰ, LC3Ⅱ and PI3K/Akt signaling pathway-associated proteins in cells. RESULTS Both medium and high concentrations of atorvastatin could significantly inhibit the viability of AGS cells (P<0.05), and 25 μmol/L atorvastatin was selected for the official experiment for follow-up experiments. Compared with the control group, the contents of glucose and lactic acid, cell proliferation rate, p-PI3K/PI3K and p-Akt/Akt ratios in the positive control group and atorvastatin group were significantly decreased (P< 0.05), and the protein expression levels of LC3 Ⅰ and LC3 Ⅱ were significantly increased (P<0.05). Compared with the atorvastatin group, the inhibitor further promoted the changes in the above indexes (P<0.05), and the activator significantly reversed the changes in the above indexes (P<0.05). CONCLUSIONS Atorvastatin could inhibit glucose metabolism and proliferation of AGS cells in human gastric cancer and promote autophagy. The mechanism may be related to the inhibition of the PI3K/Akt signaling pathway.

Objective:To explore the risk stratification value of HEART score combined with cardiac troponin (cTn) in emergency patients with chest pain.Methods:A total of 11 583 patients with chest pain who visited the Emergency Department of Zhongshan Hospital Affiliated to Fudan University from January to December 2019 were retrospectively collected. Patients who unfinished 0 h high-sensitivity cardiac troponin T (hs-cTnT) or electrocardiogram diagnosed ST-segment elevation myocardial infarction (STEMI) or lost to follow-up were excluded, and 7 057 patients were finally included. The final diagnosis of chest pain and the occurrence of major adverse cardiovascular events within 6 mon (6 m MACEs) were followed up by telephone and medical history. The HEART score of each patient was calculated by two attending physicians, and the patients were divided into the low-risk group (0-3 points), intermediate-risk group (4-6 points) and high-risk group (7-10 points) according to the final score. The risk stratification performance and safety of HEART score were observed and analyzed. A total of 1 884 patients who completed serial hs-cTnT tests were divided into groups according to HEART score (≤3 as low-risk group) and HEART score combined with serial hs-cTnT pathway (HEART score ≤3 and two hs-cTnT measurements <0.03 ng/mL as the low-risk group). The sensitivity (SE), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) of each diagnostic method were calculated to compare the diagnostic performance of the two predictive values.Results:The patients were divided into 3 groups by HEART score : 2 765 (39.2%) patients in the low-risk group, 3 438 (48.7%) in the intermediate-risk group, and 854 (12.1%) in the high-risk group. The incidence of 6 m MACEs in each group was 1.2%, 18% and 55.3%, respectively. When the low-risk threshold was 2, 23.1% of patients entered the low-risk group and the incidence of 6 m MACEs was 0.9%. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive performance of the HEART score for 6 m MACEs, and the final AUC was 0.831 ( P=0.006, 95% CI: 0.819-0.843). Regarding the occurrence of NSTEMI at the time of this visit, 4 (0.8%) patients were misdiagnosed by using the HEART score alone. Combined with serial troponin detection, the diagnostic SE and NPV were both 100%; at the same time, the diagnostic SE and NPV of 6 m MACEs in patients increased from 98.1% (95% CI: 96.9%-99.1%), 97.9% (95% CI: 96.2%-99%) to 99.1% (95% CI: 97.9%-99.7%) and 98.9% (95% CI: 97.4%-99.6%), the diagnosis SE and NPV of 6 m myocardial infarction and cardiac death in patients increased from 98% (95% CI: 96%-99.2%), 98.6% (95% CI: 97%-99.4%) to 99.2% (95% CI: 97.6%-99.8%) and 99.3% (95% CI: 98.1%-99.9%). Conclusions:The HEART score can be used for risk assessment in emergency patients with chest pain, and a threshold of 2 is recommended for the low-risk group. The diagnostic performance of HEART score combined with serial cTn is better than that of HEART score alone.
