ObjectiveTo investigate whether Shixiaosan can improve neurological function and inhibit ferroptosis in rats with cerebral ischemia-reperfusion injury (CIRI) by regulating the nuclear factor E2-related factor 2 (Nrf2)/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) pathway. MethodsA rat model of CIRI was established using the intraluminal filament method. Briefly, cervical blood vessels were separated, branches of the external carotid artery were ligated, and the common carotid artery and internal carotid artery were clamped. A nylon filament was inserted through the opening of the external carotid artery to the origin of the middle cerebral artery to block blood flow and induce cerebral ischemia. After 60-120 min of ischemia, the filament was withdrawn to restore blood flow, and the external carotid artery incision was ligated. The rats were divided into a CIRI group, a Shixiaosan low-dose (-L) group (intragastric administration of 1.26 g·kg-1 Shixiaosan), a Shixiaosan high-dose (-H) group (intragastric administration of 2.52 g·kg-1 Shixiaosan), a donepezil hydrochloride tablet (DON) group (intragastric administration of 0.45 mg·kg-1 DON), and a Shixiaosan -H + Nrf2 inhibitor (ML385) group (intragastric administration of 2.52 g·kg-1 Shixiaosan combined with intraperitoneal injection of 30 mg·kg-1 ML385). An additional 12 rats underwent cervical artery separation followed by incision suturing and served as the control group. Equal volumes of double-distilled water were administered to the CIRI and control groups. Neurological function impairment was assessed using the modified Garcia JH score. Magnetic resonance imaging was used to determine the cerebral infarct volume ratio. Hematoxylin-eosin (HE) staining and Prussian blue staining were performed to observe neuronal injury and iron accumulation in the ischemic penumbra, respectively. Transmission electron microscopy was used to examine the ultrastructure of neuronal mitochondria in the ischemic penumbra. Commercial kits were used to measure ferrous iron (Fe2+), malondialdehyde (MDA), reduced glutathione (GSH) content, and reactive oxygen species (ROS) activity in the ischemic penumbra. The BODIPY (581/591) C11 fluorescent probe was used to detect intracellular lipid peroxidation levels. Western blot was performed to detect protein expression levels of Nrf2, SLC7A11, GPX4, transferrin receptor 1 (TFRC), ferritin heavy chain (FHC), and ferritin light chain (FLC) in the ischemic penumbra. ResultsCompared with the control group, the CIRI group exhibited neuronal injury in the ischemic penumbra, characterized by reduced neuron numbers, nucleolar shrinkage, and interstitial edema. Marked iron accumulation was observed in the tissue. Neuronal mitochondria showed atrophy and rupture, with reduced mitochondrial cristae and increased membrane density. The cerebral infarct volume ratio, Fe2+ content, MDA content, ROS activity, and lipid peroxidation levels were increased, whereas the modified Garcia JH score, GSH content, and protein expression levels of Nrf2, SLC7A11, GPX4, FHC, and FLC were decreased, and TFRC protein expression was increased (P<0.05). Compared with the CIRI group, the Shixiaosan -L group, Shixiaosan -H group, and DON group showed attenuated neuronal injury in the ischemic penumbra, reduced iron accumulation, alleviated mitochondrial damage, decreased cerebral infarct volume ratio, Fe2+ and MDA contents, ROS activity, and lipid peroxidation levels, as well as increased modified Garcia JH scores, GSH content, and protein expression levels of Nrf2, SLC7A11, GPX4, FHC, and FLC, while TFRC protein expression was decreased (P<0.05). The magnitude of changes in all indicators was greater in the Shixiaosan -H group than in the Shixiaosan -L group (P<0.05). Compared with the Shixiaosan -H group, all measured indicators in the Shixiaosan -H + ML385 group showed opposite trends (P<0.05). ConclusionShixiaosan may inhibit ferroptosis and restore neurological function in rats with CIRI by activating the Nrf2/SLC7A11/GPX4 pathway.

Objective To observe the efficacy and safety of neoadjuvant sintilimab combined with chemotherapy in the treatment of patients with locally advanced resectable esophageal squamous cell carcinoma (ESCC). Methods Clinical data were collected from patients with locally advanced resectable ESCC who received neoadjuvant immunotherapy combined with chemotherapy followed by surgical treatment at the Department of Thoracic Surgery of Jining No.1 People's Hospital from April 2020 to April 2022. The endpoints included major pathological response (MPR), pathological complete response (pCR), R0 resection rate, safety, and postoperative survival. Results A total of 43 patients with ESCC who received at least one cycle of neoadjuvant immunotherapy before surgery were included. Among them, there were 31 males and 12 females with a median age of 65 years (interquartile range: 58-69). All patients successfully completed the surgery without any surgical delays. The pCR rate was 14.0% (6/43), the MPR rate was 58.1% (25/43), and the R0 resection rate was 97.7% (42/43). Patients exhibited reliable safety during neoadjuvant therapy and postoperatively. The 2-year overall survival and disease-free survival rates were 90.7% and 81.4%, respectively. Kaplan-Meier survival analysis and log-rank test revealed lower recurrence rates and better survival in the MPR patients compared to the non-MPR patients. Conclusion The combination of neoadjuvant sintilimab and chemotherapy in the treatment of patients with locally advanced resectable ESCC has demonstrated significant clinical efficacy, while also being safe and reliable.
3.Correlation between beverage dependence and sleep quality among college students
Chinese Journal of School Health 2025;46(8):1125-1129
Objective:
To explore the relationship between beverage dependence and sleep quality among college students, providing empirical evidence for improving their sleep quality.
Methods:
From December 2024 to January 2025, a convenience sampling method was used to conduct a questionnaire survey among 3 974 college students from four universities in Anhui Province. The Beverage Addiction Scale for College Students (BASCS) was used to assess beverage dependence, and the Self rating Scale of Sleep(SRSS) was used to evaluate sleep quality. A multivariate Logistic regression model was employed to analyze the relationship between beverage dependence and sleep quality, and a restricted cubic spline model was used to examine the dose response relationship between the two.
Results:
The positive rate of beverage dependence symptoms among college students was 7.6%, with positive rates of 9.6%, 13.8%, and 7.4% for the withdrawal symptoms, health effects, and dependence symptoms dimensions, respectively. The detection rate of sleep disorders was 23.6%. Multivariate Logistic regression analysis showed that after adjusting for covariates such as grade, gender, and body mass index, compared with the no beverage dependence group, students with positive beverage dependence symptoms had a higher risk of sleep disorders( OR =3.71, 95% CI =2.87-4.80, P <0.01). The OR (95% CI ) for sleep disorders among students with positive symptoms in the withdrawal symptoms, health effects, and dependence symptoms dimensions were 2.80(2.22-3.53), 2.38(1.95-2.91), and 2.45(1.89-3.18)(all P <0.01). Further analysis using a restricted cubic spline model revealed that the overall beverage dependence score and its three dimensional scores were approximately linearly related to the risk of sleep disorders among college students (all nonlinear P >0.05).
Conclusions
Beverage dependence is associated with sleep quality among college students. Schools should take multiple approaches, such as health education on beverage awareness, to improve students sleep quality.

Objective :
To investigate the diagnostic value of linear array endoscopic ultrasonography ( EUS) for common bile duct microlithiasis.
Methods :
Data of patients who attended in the hospital and diagnosed as common bile duct microlithiasis and biliary sludge by EUS were selected.A total of 85 patients with magnetic resonance cholangiopancreatography ( MRCP) examination and ERCP treatment during hospitalization were enrolled.The results of endoscopic retrograde cholangiopancreatography / endoscopic sphincterotomy ( ERCP / EST) were the gold standard for diagnosis.The results of EUS,MRCP,and diagnostic ERCP were compared with the gold standard, and the sensitivity,specificity,positive predictive value,negative predictive value,and diagnostic accuracy of the three methods were calculated,respectively.The chi-square test was used for comparison of the above indices.
Results :
Of all 85 patients,63 had positive EUS results,among whom 5 had false positive results; 22 had negative EUS results,among whom 1 had false negative results.Of all 85 patients,49 had positive MRCP results,among whom 4 had false positive results; 36 had negative MRCP results,among whom 14 had false negative results.Of all 85 patients,59 had positive diagnostic ERCP results,among whom 10 had false positive results; 26 had negative diagnostic ERCP results,among whom 10 had false negative results.The sensitivity,specificity,positive predictive value( PPV) ,negative predictive value ( NPV) ,and accuracy of EUS in diagnosing common bile duct microlithia- sis were 98. 3% ,80. 8% ,92. 1% ,95. 4% and 92. 9% ,respectively. For MRCP,these values were 76. 3% , 84. 6% ,91. 8% ,61. 1% and 78. 8% ,respectively.For diagnostic ERCP,these values were 83. 1% ,61. 5% , 83. 1% ,61. 5% and 76. 5% ,respectively.The EUS group had a significantly higher accuracy than the MRCP group ( χ2 = 6. 986,P <0. 05) and diagnostic ERCP group ( χ2 = 8. 900,P <0. 05) .The areas under the ROC curves ( AUC) and 95% CI of EUS group,MRCP group and diagnostic ERCP were 0. 895 ( 95% CI: 0. 802 - 0. 988,P<0. 001) ,0. 804 ( 95% CI: 0. 702 -0. 907,P <0. 001) and 0. 723 ( 95% CI: 0. 598 -0. 848,P = 0. 001) ,respectively.
Conclusion
EUS has a high diagnostic value in the diagnosis of common bile duct microli- thiasis and thus can be used as the preferred examination before therapeutic ERCP.

Objective To explore the mechanism of action of Huaier (Vanderbylia robiniophila) against pancreatic cancer. Methods The chemical components and targets of Huaier (Vanderbylia robiniophila) were searched through the Herb database. Pancreatic cancer-related targets were screened from GeneCards, NCBI, and DisGeNET online databases, and a Venn diagram was drawn to obtain the intersection targets of drugs and diseases. The protein-protein interaction (PPI) network was constructed using the String platform, and a series of network diagrams were drawn using Cytoscape 3.8.0 software to screen core targets and perform GO analysis and KEGG pathway enrichment analysis on the target genes. Finally, the key active components were molecularly docked with potential target genes using AutoDock software. The KEGG enrichment top 20 pathways and the whole-genome association analysis data of pancreatic cancer were used to further validate the results using the Open GWAS database through Mendelian randomization analysis. Results A total of 4 effective components of Huaier (Vanderbylia robiniophila) were identified, 112 drug-disease intersection targets, the main active components were kaempferol, rutin, genistein, and glucuronic acid, and the core targets were mitogen-activated protein kinase 8 (MAPK8), uridine diphosphate(UDP)-glucuronic acid transferase 1 family peptide A1 (UGT1A1), and superoxide dismutase 2 (SOD2). The mechanism of action may be related to pancreatic cancer, tumor necrosis factor(TNF) signaling pathway, and interleukin(IL)-17 signaling pathway. The molecular docking showed that the main active components had good docking activity with the key targets. After screening, 73 genes were retained, and 24,195,229 single nucleotide polymorphism(SNP) were used for two-sample Mendelian randomization analysis. The analysis results showed that MAPK8 may be an important therapeutic target for pancreatic cancer. Conclusions Huaier (Vanderbylia robiniophila) may exert an anti-pancreatic cancer effect by acting on MAPK8, providing initial theoretical evidence for further verifying the mechanism of action of Huaier in treating pancreatic cancer.

Lung cancer is the cancer with the highest incidence of morbidity and mortality in the world, and the number of lung cancer cases in China is also increasing year by year, which seriously threatens the life and health of human beings. Circulating tumor cells (CTCs) refer to the tumor cell that falls off from primary tumor tissue or metastatic focus into the peripheral blood, which is the key to tumor metastasis. Currently, there are various methods for CTCs testing, each with its own advantages and disadvantages. In recent years, there have been numerous studies on the application of CTCs in lung cancer around the world. Further exploration of the progress of clinical application of CTCs in lung cancer can provide a new basis for the role of CTCs in early diagnosis, efficacy assessment and prognostic monitoring of lung cancer.

Objective To describe the significance of the pretreatment inflammatory indicators in predicting the prognosis of patients with esophageal squamous cell carcinoma (ESCC) after undergoing radical radiotherapy. Methods The data of 246 ESCC patients who underwent radical radiotherapy were retrospectively collected. Receiver operating characteristic (ROC) curves were drawn to determine the optimal cutoff values for platelet-lymphocyte ratio (PLR), neutrophil-lymphocyte ratio (NLR), and systemic immune-inflammation index (SII). The Kaplan-Meier method was used for survival analysis. We conducted univariate and multivariate analyses by using the Cox proportional risk regression model. Software R (version 4.2.0) was used to create the nomogram of prognostic factors. Results The results of the ROC curve analysis showed that the optimal cutoff values of PLR, NLR, and SII were 146.06, 2.67, and 493.97, respectively. The overall response rates were 77.6% and 64.5% in the low and high NLR groups, respectively (P<0.05). The results of the Kaplan-Meier survival analysis revealed that the prognosis of patients in the low PLR, NLR, and SII group was better than that of patients in the high PLR, NLR, and SII group (all P<0.05). The results of the multivariate Cox regression analysis showed that gender, treatment modalities, T stage, and NLR were independent factors affecting the overall survival (OS). In addition, T stage and NLR were independent factors affecting the progression-free survival (PFS) (all P<0.05). The nomogram models of OS and PFS prediction were established based on multivariate analysis. The C-index values were 0.703 and 0.668. The calibration curves showed excellent consistency between the predicted and observed OS and PFS. Conclusion The pretreatment values of PLR, NLR, and SII are correlated with the prognosis of patients with ESCC who underwent radical radiotherapy. Moreover, NLR is an independent factor affecting the OS and PFS of ESCC patients. The NLR-based nomogram model has a good predictive ability.

Objective:To investigate and analyze the safety of empirical or experimental medication (EEM) for adult-onset Still disease (AOSD) before diagnosis.Methods:The AOSD inpatients admitted to the Second Hospital of Jilin University from January 1, 2019 to December 31, 2023 were collected through hospital information system, and those who were misdiagnosed on admission were screened out. The main clinical characteristics, laboratory tests, misdiagnosis situation, the use of EEM and their adverse drug reactions (ADR), and the potential drug-drug interactions in the misdiagnosed patients were analyzed by descriptive statistics.Results:During the set time period, a total of 49 patients with AOSD were admitted to the hospital, of which 16 (32.7%) were misdiagnosed with other diseases on admission. Among the 16 patients, 10 were male and 6 were female, with a median age of 53 years. The main clinical manifestations were fever (in 15 patients), arthralgia/arthritis (in 10 patients), lymphadenopathy (in 10 patients), rash (in 9 patients), pleural or pericardial effusion (in 6 patients), pneumonia (in 5 patients), splenomegaly (in 4 patients) and sore throat (in 4 patients). Abnormalities in laboratory tests included white blood cell count elevation (in 13 patients), platelets count elevation (in 8 patients), serum ferritin elevation (>500 μg/L, in 12 patients), and abnormal liver function (in 9 patients). The median time of treatment before admission was 5.5 months (11 days to 27.0 months), and the median time from admission to diagnosis of AOSD was 12 days. Before the diagnosis of AOSD, all patients received a long time of EEM, including antibiotics, traditional Chinese medicine preparations, liver-protection drugs, anti-allergic drugs and antiviral drugs in 15, 12, 11, 3 and 2 patients, respectively. Four patients experienced ADRs related to EEM, all of which were caused by antibiotics. There were potential interactions in the therapeutic drugs in 4 patients.Conclusion:The misdiagnosis rate of AOSD was high. Patients might had accepted multiple EEMs before the definite diagnosis, which posed risks of ADRs and drug interactions.
