ObjectiveTo explore the mechanism of Yinchenhao Tang regulating the tumor necrosis factor receptor superfamily member 6 （Fas）/cysteine protease-8 （Caspase-8）/cysteine protease-3 （Caspase-3） signaling pathway to inhibit hepatocyte apoptosis and improve cholestatic liver injury （CLI）. MethodsAmong 48 Wistar rats，12 rats were randomly selected as the blank group，and the other rats were administered alpha-naphthalene isothiocyanate （ANIT） by gavage to induce a CLI model. The modeling rats were randomly divided into the model group， the ursodeoxycholic acid group（0.1 g·kg^-1） and the Yinchenhao Tang group（9.23 g·kg^-1），with 12 rats in each group. The rats in each group were given corresponding drugs by gavage for three consecutive days. The levels of alanine aminotransferase （ALT），aspartate aminotransferase （AST），alkaline phosphatase （ALP），gamma-glutamyl transpeptidase （γ-GT），total bilirubin （TBil） and total bile acid （TBA） in serum were detected. The levels of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） in liver tissue were detected. The histopathological changes of the liver were observed by hematoxylin-eosin （HE） staining. The protein and mRNA expressions of Fas，Caspase-8，Caspase-3，B-cell lymphoma-2 （Bcl-2） associated X protein （Bax） and Bcl-2 in liver tissue were detected by Western blot and real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with those in the blank group，the levels of ALT，AST，ALP，γ-GT，TBA and TBil in serum of the model group were significantly increased （P<0.01）. The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly increased （P<0.01）. The arrangement of hepatocytes was disordered，and inflammatory cell infiltration and bile duct epithelial cell proliferation were observed. The protein and mRNA expressions of Fas，Caspase-8，Caspase-3 and Bax in liver tissue were significantly increased（P<0.05，P<0.01），while the protein and mRNA expressions of Bcl-2 were significantly decreased （P<0.05，P<0.01）. Compared with those in the model group，the levels of ALP，γ-GT，TBA and TBil in the serum of rats in the ursodeoxycholic acid group were significantly decreased. The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly decreased（P<0.05，P<0.01）. The protein and mRNA expressions of Fas，Caspase-8，Caspase-3 and Bax in liver tissue were significantly decreased （P<0.05，P<0.01），while the mRNA expression of Bcl-2 was significantly increased （P<0.05，）. The levels of ALT，AST，γ-GT，TBA and TBil in the serum of rats in the Yinchenhao Tang group were significantly decreased （P<0.01）. The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly decreased （P<0.05，P<0.01）. The protein expression of Fas and Bax and the mRNA expression of Fas，Caspase-8，Caspase-3 and Bax in liver tissue were significantly decreased （P<0.05，P<0.01），while the protein and mRNA expression of Bcl-2 were significantly increased （P<0.05，P<0.01）. Hepatocyte injury，inflammatory cell infiltration and proliferation of bile duct epithelial cells were reduced. ConclusionYinchenhao Tang can ameliorate CLI，and its mechanism may be related to inhibiting hepatocyte apoptosis mediated by the Fas/Caspase-8/Caspase-3 signaling pathway.

ObjectiveTo study the mechanism of Yinchenhao Tang on the improvement of cholestatic liver injury （CLI） by inhibiting toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear transcription factor-κB （NF-κB） pathway via regulating farnesol X receptor （FXR）. MethodsA total of 40 Wistar male rats were randomly selected， with 10 as a blank group，and the remaining rats were subjected to the CLI model induced by alpha-naphthalene isothiocyanate （ANIT）. After modeling，they were randomly divided into the model group， the ursodeoxycholic acid （0.1 g·kg^-1） group and the Yinchenhao Tang （9.23 g·kg^-1） group，with 10 animals in each group. Each administration group was given the corresponding drug by intragastric administration for three consecutive days. Alanine aminotransferase （ALT），aspartate aminotransferase （AST），alkaline phosphatase （ALP），γ-glutamyl transpeptidase （γ-GT），total bile acid （TBA），total bilirubin （TBil） and direct bilirubin （DBil） levels in serum were detected. Tumor necrosis factor-α （TNF-α），interleukin-1β （IL-1β），and interleukin-6 （IL-6） levels in liver tissue were detected. Real-time PCR was used to detect the mRNA expression of FXR，TLR4，MyD88，NF-κB，F4/80，TNF-α，IL-1β and IL-6 in liver tissue. Western blot was used to detect protein expression of FXR，TLR4，MyD88 and NF-κB in liver tissue. The histopathological changes of the liver were observed by hematoxylin-eosin （HE） staining. ResultsCompared with those in the blank group，ALT，AST，ALP，γ-GT，TBA，TBil and DBil levels in serum of rats in the model group were significantly increased （P<0.01）. The levels and mRNA expression of TNF-α，IL-1β and IL-6 in liver tissue were significantly increased （P<0.01），and the mRNA and protein expressions of FXR in liver tissue were decreased （P<0.01）. The mRNA and protein expressions of TLR4，MyD88 and NF-κB and the mRNA expression of F4/80 were obviously increased （P<0.05，P<0.01）. Hepatic histopathology showed inflammatory cell infiltration and proliferative changes of bile duct epithelial cells. Compared with those in the model group，ALT，ALP，γ-GT，TBA，TBil and DBil levels in serum of rats in the ursodeoxycholic acid group were obviously decreased （P<0.05，P<0.01），and the levels and mRNA expression of TNF-α，IL-1β and IL-6 in liver tissue were obviously decreased （P<0.05，P<0.01）. The mRNA and protein expressions of TLR4，MyD88 and NF-κB and the mRNA expression of F4/80 in liver tissue were obviously decreased （P<0.05，P<0.01）. ALT，AST，ALP，γ-GT，TBA，TBil and DBil levels in the serum of rats in the Yinchenhao Tang group were obviously decreased （P<0.05，P<0.01），and the levels and mRNA expression of TNF-α，IL-1β and IL-6 in liver tissue were obviously decreased （P<0.01）. The mRNA and protein expressions of FXR in liver tissue were significantly increased，and the mRNA expressions of TLR4，MyD88，NF-κB，and F4/80， as well as the protein expressions of TLR4 and NF-κB were obviously decreased （P<0.05，P<0.01）. The inflammatory cell infiltration of liver tissue and the proliferation of bile duct epithelial cells decreased. ConclusionYinchenhao Tang has an obvious protective effect on CLI，and its mechanism may be related to regulating FXR to inhibit TLR4/MyD88/NF-κB pathway-mediated inflammatory response.

Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

BACKGROUND:The authors found that when the bilateral percutaneous vertebral augmentation is used to treat osteoporotic vertebral compression fractures with a total bone cement injection of 4 mL or more,different distribution patterns were usually presented on the X-rays;however,there were few reports addressing the effects of these patterns of bone cement distribution on the biomechanical properties of fractural vertebrae. OBJECTIVE:To further explore the biomechanical effects of different bone cement filling doses and distribution patterns on biomechanics of the fractural vertebrae using the finite element method. METHODS:The L1-L3 finite element models of osteoporosis were established,and the vertebral compression fractures were simulated in L2.Four distribution patterns bilateral partial fusion(FH type),full fusion(FO type),symmetrical separation(SA type),and asymmetric segregation(SN type)were simulated in 4 and 6 mL injections in the osteoporotic vertebral compression fracture models,respectively,and a total of nine sets of models were obtained.These models were solved under the same boundary conditions and compared with the stress and displacement of the L2 fractural vertebra. RESULTS AND CONCLUSION:(1)The maximum stresses of the nine groups of models were concentrated in the L2 fractural area,and the maximum stress and maximum displacement of each filling model were lower than in the osteoporotic vertebral compression fracture model,indicating the effectiveness of bone cement filling in the treatment of osteoporotic vertebral compression fracture.(2)Compared with 4 mL bone cement filling,6 mL bone cement filling could significantly reduce the stress of fractured vertebrae and enhance the strength of fractured vertebrae while improving the stability of fractured vertebrae.(3)In the same state of movement,the FH type stress was the least,followed by the SA type,both of which were close.FO type stress was the largest,especially in the lateral bend,which might be associated with its cluster shape resulting in the concentration of lateral stress.In the aspect of displacement,FH type was the least and FO type was the largest.(4)The results show that increased dose of bone cement injection reduces fractural vertebral stress and improves stability,but increases the risk of leakage.Bilateral symmetrical dispersed bone cement(FH type,SA type)is superior in restoring vertebral strength and stability than full fusion(FO type),asymmetric separated(SN type)bone cement.Therefore,when clinically performing bilateral percutaneous vertebral augmentation treatment of osteoporotic vertebral compression fractures,the bilateral symmetric dispersions of the distribution are first guaranteed;priority is recommended for FH type distribution,for appropriate stress stimulation and best stability.

BackgroundSevere mental disorders represent a major public health concern due to the high disability rates and substantial disease burden， which has garnered significant national attention and prompted their inclusion in public health project management systems. However， credible evidence regarding the current status of disease management and factors influencing disease stabilization among patients with severe mental disorders in Luzhou City， Sichuan Province， remains limited. ObjectiveTo investigate the current management status of patients with severe mental disorders in Luzhou City， Sichuan Province， and to analyze influencing factors of disease stabilization among patients under standardized care， so as to provide evidence-based insights for developing targeted management strategies to optimize clinical interventions for this patient population. MethodsIn March 2023， data were extracted from the Sichuan Mental Health Service Comprehensive Management Platform for patients with severe mental disorders in Luzhou City who received management between December 2017 and December 2022. Information on mental health service utilization and clinical status changes was collected. Trend analysis was conducted to evaluate temporal changes in key management indicators for severe mental disorders in Luzhou City. Logistic regression analysis was employed to identify factors influencing the disease stabilization or fluctuation of these patients. ResultsThis study enrolled a total of 20 232 patients. In Luzhou City， the stabilization rate and standardized management rate of severe mental disorders were 94.89% and 79.36% in 2017， respectively， which increased to 95.33% and 96.92% by 2022. The regular medication adherence rate rose from 34.42% in 2018 to 86.81% in 2022. In 2022， the regular medication adherence rate was 71.80% for schizophrenia， 55.26% for paranoid psychosis， and 51.43% for schizoaffective disorder. Multivariate analysis identified the following protective factors for disease stabilization： age of 18~39 years （OR=0.613， 95% CI： 0.409~0.918）， age of 40~65 years （OR=0.615， 95% CI： 0.407~0.931）， urban residence （OR=0.587， 95% CI： 0.478~0.720）， and regular medication adherence （OR=0.826， 95% CI： 0.702~0.973）. Risk factors for disease fluctuation included poor （OR=1.712， 95% CI： 1.436~2.040）， non-inclusion in care-support programs （OR=1.928， 95% CI： 1.694~2.193）， non-participation in community rehabilitation （OR=2.255， 95% CI： 1.930~2.634）， and intermittent medication adherence （OR=3.893， 95% CI： 2.548~5.946）. ConclusionThe stability rate， standardized management rate， and regular medication adherence rate of patients with severe mental disorders in Luzhou City have shown a year-by-year increase. Age， household registration status， economic condition， medication compliance， and community-based rehabilitation were identified as influencing factors for disease fluctuation in these patients. ［Funded by Luzhou Science and Technology Plan Project （number， 2022-ZRK-186）］

Objective To investigate the effects and related mechanisms of mitochondrial-derived peptide MOTS-c on glycochenodeoxycholic acid (GCDCA)-induced injury in human hepatocytes (THLE-3 cells). Methods THLE-3 cells were cultured in vitro and treated with different concentrations of GCDCA and MOTS-c. The optimal concentrations of GCDCA and MOTS-c were determined by cell counting kit (CCK)-8 method. Subsequently, THLE-3 cells were treated or pre-treated with GCDCA (200 µmol/L), MOTS-c (15, 30, 60 µmol/L), the multidrug resistance protein 2 (MRP2) inhibitor Probenecid (500 µmol/L), and the nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor ML385 (10 µmol/L). Cell proliferation was assessed by CCK-8 method. Lactate dehydrogenase (LDH) levels in the culture medium were measured by biochemical method. Cell apoptosis rates were determined by flow cytometry. MRP2 messenger RNA (mRNA) levels were detected by real-time quantitative polymerase chain reaction (RT-qPCR). MRP2 and Nrf2 protein expression levels were analyzed by Western blotting. Results As the concentration of GCDCA increased, the proliferation activity of THLE-3 cells gradually decreased, while LDH activity in the culture medium and apoptosis levels increased, and the expression levels of MRP2 in the cells decreased (all P<0.05). Treatment with 30 and 60 µmol/L MOTS-c significantly enhanced the proliferation activity of THLE-3 cells exposed to GCDCA, upregulated the expression of MRP2 and Nrf2, and reduced LDH activity and apoptosis levels (all P<0.05). Co-treatment with Probenecid partially reversed the protective effects of MOTS-c on GCDCA-induced THLE-3 cells injury, while co-treatment with ML385 partially inhibited the induction of MRP2 expression by MOTS-c in THLE-3 cells exposed to GCDCA. Conclusions MOTS-c may alleviate GCDCA-induced injury in human hepatocytes (THLE-3 cells), and its mechanism may be related to the upregulation of MRP2 expression mediated by Nrf2.

Objective: To explore the relationship between sleep characteristics, physical activity patterns, with depressive and anxiety symptoms in college students, so as to provide reference for student mental health promotion. Methods: From September to November 2023, a convenience sampling method was used to select 7 954 college students aged 18-22 years from 9 universities in Shanghai, Hubei, and Jiangxi. Assessments were conducted using the International Physical Activity Questionnaire Short-Form (IPAQ-SF), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Scale-7 (GAD-7), and Pittsburgh Sleep Quality Index (PSQI) to evaluate physical activity, depressive and anxiety symptoms, and sleep quality, respectively. Logistic regression analysis was employed to explore the impact of sleep characteristics and physical activity patterns on depressive and anxiety symptoms and their comorbidity among college students. Results: The detection rates for depressive symptoms, anxiety symptoms, and comorbid depression and anxiety symptoms were 25.67%, 35.39%, and 23.15%, respectively. Factors such as gender, grade, household registration, parental education level, annual family income, family structure, and dietary habits were all associated with the detection rates of depressive and anxiety symptoms and their comorbidity (χ2=4.41-118.39, P<0.05). Physical activity patterns, sleep duration, sleep quality, and sleepwake characteristics were also associated with the occurrence of depressive and anxiety symptoms and their comorbidity (χ2=9.66-627.70, P<0.05). Logistic regression analysis showed that college students who stayed up late and slept less than 7 had the highest risk of depressive and anxiety symptoms and their comorbidity (OR=1.93, 1.85, 1.88, P<0.05). Compared to regular physical activity patterns, insufficient physical activity patterns were associated with an increased risk of depressive and anxiety symptoms (all OR=1.18, P<0.05). Further stratified analysis results showed that the risk of depression, anxiety and their comorbidity increased in college students who stayed up late and slept less than 7 h, went to bed before midnight and slept less than 7 h, or went to bed before midnight and slept more than 7 h but did not have sufficient physical activity (P<0.05). Conclusions Sleep characteristics and physical activity patterns significantly affect depressive and anxiety symptoms in college students. Universities should strengthen sleep management and implement flexible physical activity interventions to help students establish healthy lifestyles.
