Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

OBJECTIVE To build a Tibetan-language medication service platform based on “internet+” and evaluate its effect on improving medication compliance and safety of Tibetan patients with chronic disease. METHODS Medication guidance contents of commonly used drugs in the outpatient department were summarized， translated and recorded in Tibetan-language or video to form a “text-audio-video” multi-dimensional “internet+ ” Tibetan-language medication service platform. A total of 387 Tibetan outpatients with chronic disease in our hospital after the implementation of “internet+” Tibetan-language medication service platform （from January 2024 to June 2024） in our hospital were selected as the intervention group， and 387 Tibetan outpatients before the implementation （from January 2023 to June 2023） were selected as the control group. Patients in the control group received conventional window-based Chinese-language medication services， while patients in the intervention group received both conventional window-based Chinese-language medication service and “internet+ ” Tibetan-language medication service. The medication compliance of patients was evaluated using the 12-item Medication Compliance Scale. A six-level causality assessment was conducted as the principles for analyzing adverse drug reactions （ADR） set by the National Center for ADR Monitoring. Additionally， statistics were compiled on the occurrence of ADR that were assessed as “definite”“probable” or “possible” in the causality assessment. RESULTS The proportion （31.0%） of patients with good medication compliance and compliance scores [39.0 （37.0，42.0）] of patients in the intervention group were significantly better than control group [7.0%， 21.0（19.0， 23.0）]（ P＜0.05）. There were no statistically significant differences in the incidence of various types of ADR or the overall incidence between the two groups （P＞0.05）. CONCLUSIONS The “internet+” Tibetan-language medication service platform is constructed successfully； the service can effectively improve the medication compliance of Tibetan-language patients， but its effect on improving the medication safety of patients is limited.

Objective To investigate the prevalence of common diseases among primary and secondary school students in Yichang City from 2019 to 2022, and to provide a scientific basis for formulating effective intervention measures in the future. Methods By random cluster sampling , 7 schools in urban areas and 5 schools in suburban counties were selected to screen common diseases such as myopia, dental caries, obesity and abnormal spinal curvature. Descriptive epidemiological methods were employed for statistical analysis. Results A total of 17 023 primary and secondary school students were screened from 2019 to 2022. The overall detection rate of common diseases from high to low was myopia (54.12%), caries (36.75%), overweight (15.17%), obesity (11.88%), malnutrition (5.80%), and abnormal spinal curvature (3.49%). The detection rates of myopia and abnormal curvature of the spine showed an increasing trend with years and school stages, while the detection rates of malnutrition and dental caries showed a decreasing trend with years and school stages. The detection rates of overweight and obesity showed no trend difference with years, and the detection rates of obesity showed a decreasing trend with school stages. The rates of myopia, overweight and obesity were higher in urban areas than those in suburban counties, and the rate of dental caries was higher in suburban counties than that in urban areas. The prevalence of overweight, obesity, and malnutrition in boys was higher than that in girls. The prevalence of myopia and dental caries in girls was higher than that in boys. The above differences were statistically significant (all P<0.05). Conclusion Myopia, dental caries, obesity, and abnormal curvature of the spine are the current focus of the prevention and treatment of common diseases in students. There are great differences between different regions, school stages, and genders. The ^“tripartite linkage^” of schools, families, and communities should be achieved with the joint efforts of the education and health departments to actively take targeted intervention measures to reduce the prevalence.

BACKGROUND:Cadmium is a common environmental pollutant,which can damage multiple organs and tissues,such as the kidney and bone,but its effect on annulus fibrosus cells in the intervertebral disc has been less reported. OBJECTIVE:To investigate the effect of cadmium chloride on the senescence of annulus fibrosus cells and the role of PI3K/Akt signaling pathway. METHODS:Annulus fibrosus cells from Sprague-Dawley rat intervertebral discs were harvested and passage 3 cells were intervened with different concentrations of cadmium chloride(0,1,5,10,20 μmol/L).Cell viability and proliferation were detected by cell counting kit-8 assay.Transcriptome sequencing and Kyoto Encyclopedia of Genes and Genomes functional enrichment analysis were performed on annulus fibrosus cells with or without cadmium chloride addition.Passage 3 annulus fibrosus cells were divided into control group,cadmium chloride group and LY294002 group.Cell proliferation rate was detected by EdU method,positive cell rate was detected by senescence-associated β-galactosidase staining,and expressions of senescence-associated proteins(p16,p21 and p53)and p-Akt at protein and mRNA levels were measured by western blot,RT-PCR and immunofluorescence. RESULTS AND CONCLUSION:5 μmol/L cadmium chloride could inhibit the proliferation of annulus fibrosus cells.Results from the Kyoto Encyclopedia of Genes and Genomes functional enrichment analysis showed that the main signal transduction pathways included PI3K/Akt,cell cycle and p53 signaling pathways,which were related to cell senescence and proliferation.PI3K/Akt signaling pathways with significant differential expression were selected for validation.Compared with the control group,the EdU-positive rate was significantly decreased in the cadmium chloride group(P<0.05),while the β-galactosidase-positive rate,the expression of senescence-associated proteins(p16,p21 and p53)and p-Akt significantly increased(P<0.05).Compared with the cadmium chloride group,the EdU-positive rate and p-Akt expression were significantly decreased in the LY294002 group(P<0.05),while the β-galactosidase-positive rate and the expression of senescence-associated proteins(p16,p21 and p53)significantly increased(P<0.05).To conclude,cadmium chloride can regulate the senescence of annulus fibrosus cells by activating the PI3K/Akt signaling pathway,thereby inducing the occurrence and progression of intervertebral disc degeneration.

OBJECTIVE: To determine whether monotropein has an anticancer effect and explore its potential mechanisms against colorectal cancer (CRC) through network pharmacology and molecular docking combined with experimental verification. METHODS: Network pharmacology and molecular docking were used to predict potential targets of monotropein against CRC. Cell counting kit assay, plate monoclonal assay and microscopic observation were used to investigate the antiproliferative effects of monotropein on CRC cells HCT116, HT29 and LoVo. Flow cytometry and scratch assay were used to analyze apoptosis and cell cycle, as well as cell migration, respectively in HCT116, HT29, and LoVo cells. Western blotting was used to detect the expression of proteins related to apoptosis, cell cycle, and cell migration, and the expression of proteins key to the Akt pathway. RESULTS: The Gene Ontology and Reactome enrichment analyses indicated that the anticancer potential of monotropein against CRC might be involved in multiple cancer-related signaling pathways. Among these pathways, RAC-beta serine/threonine-protein kinase (Akt1, Akt2), cyclin-dependent kinase 6 (CDK6), matrix metalloproteinase-9 (MMP9), epidermal growth factor receptor (EGFR), cell division control protein 42 homolog (CDC42) were shown as the potential anticancer targets of monotropein against CRC. Molecular docking suggested that monotropein may interact with the 6 targets (Akt1, Akt2, CDK6, MMP9, EGFR, CDC42). Subsequently, cell activity of HCT116, HT29 and LoVo cell lines were significantly suppressed by monotropein (P<0.05). Furthermore, our research revealed that monotropein induced cell apoptosis by inhibiting Bcl-2 and increasing Bax, induced G₁-S cycle arrest in colorectal cancer by decreasing the expressions of CyclinD1, CDK4 and CDK6, inhibited cell migration by suppressing the expressions of CDC42 and MMP9 (P<0.05), and might play an anticancer role through Akt signaling pathway. CONCLUSION Monotropein exerts its antitumor effects primarily by arresting the cell cycle, causing cell apoptosis, and inhibiting cell migration. This indicates a high potential for developing novel medication for treating CRC.

ObjectiveBased on the ultrastructure of enteric nervous system （ENS）-platelet-derived growth factor receptor α positive （PDGFRα⁺） cell - smooth muscle cell （SMC） network， the effect and mechanism of Shuwei Decoction （舒胃汤） for rats with functional dyspepsia （FD） of liver-depression and spleen-deficiency syndrome were explored. MethodsFifty SD rats were divided into blank group， model group， low-， medium- and high-dose Shuwei Decoction groups randomly， with 10 rats in each group. The blank group was not set up， and the other 4 groups were set up with the modified composite cause （chronic restraint stress + tail irritation + excessive fatigue + diet disorder） for 21 days， resulting in FD model rats with liver-depression and spleen-deficiency syndrome. After successful modelling， rats in the low-， medium- and high-dose groups were given 3.78， 7.56 and 15.12 g/（kg·d） of Shuwei Decoction by gavage， respectively， while rats in the blank group and the model group were given 10 ml/（kg·d） of saline by gavage； all of them were given gavage once a day for 14 days. Body mass increase were collected before and after gavage， and compared after the experiment； the elevated cross maze experiment was conducted to observe the percentage of staying time and the percentage of times entering the open arm of rats； the gastric emptying rate and small intestinal propulsion rate were measured by black semi-solid paste； HE staining was used to observe histopathology of the gastric antrum； the Western Blotting and RT-qPCR were used to detect the expression levels of PDGFRα， small conductance calcium activated potassium （SK3）， and purinergic G protein-coupled receptor P2Y1 （P2Y1 R）， and mRNA expression in gastric antrum； immunofluorescence double staining was used to detect the co-localization of PDGFRα with receptor tyrosine kinase （C-kit）， protein gene product 9.5 （PGP9.5）， Sk3， and smooth muscle cells （SMCs） in gastric sinusoidal tissues； and transmission electron microscopy was used to observe the ultrastructure of the ENS-PDGFRα⁺ cell-SMC network. ResultsHE staining results showed that the mucosal folds of gastric tissue were clear in all groups， no organic lesions such as bleeding， ulceration and swelling were observed， and the arrangement of gastric glands in the lamina propria of gastric sinusoidal tissues in model group and low-dose Shuwei Decoction group was disordered. The arrangement of gastric glands in lamina propria in medium- and high-dose Shuwei Decoction groups was more orderly， and the lesion degree was less than that in model group and low-dose Shuwei Decoction group. Compared with the blank group， the growth value of body mass， the percentage of open arm retention time， the percentage of times entering the open arm， the small intestine propulsion rate， and the gastric empty rate of rats in the model group significantly decreased after gavage； the expressions of PDGFRα， Sk3， P2Y1 protein and mRNA in gastric sinusoidal tissues decreased； the co-localization expression of PDGFRα with C-kit， Sk3， SMC and PGP9.5 significantly decreased （P＜0.05 or P＜0.01）； the ultrastructure of ENS-PDGFRα⁺ cell-SMC network was damaged without gap junction. Compared with model group and low-dose Shuwei Decoction group， the growth value of body mass， the percentage of open arm retention time， the percentage of times entering the open arm， the small intestine propulsion rate， and the gastric empting rate of rats in medium- and high-dose Shuwei Decoction groups increased after gavage； the expressions of PDGFRα， Sk3， P2Y1 protein and mRNA in gastric sinusoidal tissues increased； the co-localization expression of PDGFRα with C-kit， Sk3， SMC and PGP9.5 significantly increased （P＜0.05 or P＜0.01）； the ultrastructure of ENS-PDGFRα⁺ cell-SMC network was intact. Compared with medium-dose Shuwei Decoction group， the protein expressions of PDGFRα， Sk3 and P2Y1， the mRNA expressions of PDGFRα and Sk3， and the co-localization expressions of PDGFRα and C-kit， Sk3， SMC， and PGP9.5 in high-dose Shuwei Decoction group increased （P＜0.05 or P＜0.01）. ConclusionShuwei Decoction can improve the pathological lesion of the gastric antrum in the FD model rats with liver-depression and spleen-deficiency syndrome and increase the gastric emptying rate as well as the small intestinal propusion rate. The mechanism of Shuwei Decoction on FD rats with liver-depression and spleen-deficiency syndrome is related to the protection of the ultrastructural integrity of ENS-PDGFRα⁺ cell-SMC network.

ObjectiveTo observe the clinical effect of crocin tablets （CRO） combined with micropump infusion of doxorubicin in the prevention of acute cardiotoxicity in the patients with diffuse large B-cell lymphoma （DLBCL） and explore the related mechanism. MethodThe patients with DLBCL treated in the Huangshi Central Hospital from October 2022 to October 2023 were selected， and 92 patients who met the inclusion criteria were randomly assigned to a control group and an observation group at a ratio of 1∶1， with 46 patients in each group. The control group underwent conventional intravenous infusion of doxorubicin， and the observation group received CRO combined with micropump infusion of doxorubicin. The changes of abnormal ECG， myocardial injury markers， cardiac function indicators， oxidative stress， inflammatory mediators， and hemorheological indexes before and after chemotherapy were compared between the two groups. ResultThe incidence of abnormal ECG in the observation group was 23.91% （11/46）， which was lower than that （54.35%， 25/46） in the control group （χ²=8.944， P<0.01）. On day 8 after chemotherapy， the abnormal rates of creatine kinase-MB （CK-MB） and cardiac troponin I （cTnI） in the observation group were lower than those in the control group （χ²=4.423， 4.857， both P<0.05）. Compared with the control group after chemotherapy， the observation group showed lowered level of N-terminal pro-B-type natriuretic peptide， elevated left ventricular ejection fraction and levels of total antioxidant capacity and superoxide dismutase （P<0.01）， declined levels of interleukin-6 and tumor necrosis factor-α （P<0.01）， and decreased low whole blood viscosity， high whole blood viscosity， plasma viscosity， and fibrinogen （P<0.01）. ConclusionCRO combined with micropump infusion of doxorubicin can mitigate acute cardiotoxicity， reduce the incidence of abnormal ECG， protect cardiomyocytes， and improve the cardiac function by exerting the antioxidant and anti-inflammatory effects and improving blood flow.
