In addition, exosomes derived from mesenchymal stem cells have shown anti-inflammatory effects in the treatment of a variety of diseases. However, whether they can protect neurons in Parkinson’s disease by inhibiting microglia-mediated inflammatory responses is not yet known. In this study, exosomes were isolated from human umbilical cord mesenchymal stem cells and injected into a 6-hydroxydopamine-induced rat model of Parkinson’s disease. We found that the exosomes injected through the tail vein and lateral ventricle were absorbed by dopaminergic neurons and microglia on the affected side of the brain, where they repaired nigral-striatal dopamine system damage and inhibited microglial activation. Furthermore, in an in vitro cell model, pretreating lipopolysaccharide-stimulated BV2 cells with exosomes reduced interleukin-1β and interleukin-18 secretion, prevented the adoption of pyroptosis-associated morphology by BV2 cells, and increased the survival rate of SH-SY5Y cells. Potential targets for treatment with human umbilical cord mesenchymal stem cells and exosomes were further identified by high-throughput microRNA sequencing and protein spectrum sequencing. Our findings suggest that human umbilical cord mesenchymal stem cells and exosomes are a potential treatment for Parkinson’s disease, and that their neuroprotective effects may be mediated by inhibition of excessive microglial proliferation.展开更多

文摘Introduction:DNA polymerases are crucial for maintaining genome stability and influencing tumorigenesis.However,the clinical implications of DNA polymerases in tumorigenesis and their potential as anti-cancer therapy targets are not well understood.Methods:We conducted a systematic analysis using TCGA Pan-Cancer Atlas data and Gene Set Cancer Analysis results to examine the expression profiles of 15 DNA polymerases(POLYs)and their clinical correlations.We also evaluated the prognostic value of POLYs by analyzing their expression levels in relation to overall survival time(OS)using Kaplan-Meier survival curves.Additionally,we investigated the correlations between POLY expression and immune cells,DNA damage repair(DDR)pathways,and ubiquitination.Drug sensitivity analysis was performed to assess the relationship between POLY expression and drug response.Results:Our analysis revealed that 14 out of 15 POLYs exhibited significantly distinct expression patterns between tumor and normal samples across most cancer types,except for DNA nucleotidylexotransferase(DNTT).Specifically,POLD1 and POLE showed elevated expression in almost all cancers,while POLQ exhibited high expression levels in all cancer types.Some POLYs showed heightened expression in specific cancer subtypes,while others exhibited low expression.Kaplan-Meier survival curves demonstrated significant prognostic value of POLYs in multiple cancers,including PAAD,KIRC,and ACC.Cox analysis further validated these findings.Alteration patterns of POLYs varied significantly among different cancer types and were associated with poorer survival outcomes.Significant correlations were observed between the expression of POLY members and immune cells,DDR pathways,and ubiquitination.Drug sensitivity analysis indicated an inverse relationship between POLY expression and drug response.Conclusion:Our comprehensive study highlights the significant role of POLYs in cancer development and identifies them as promising prognostic and immunological biomarkers for various cancer types.Additionally,targeting POLYs therapeutically holds promise for tumor immunotherapy.
文摘Objective:To explore the effect of cognitive behavioral therapy on self-care in thyroid cancer patients.Methods:A total of 144 thyroid cancer patients treated at the Affiliated Hospital of Hebei University from January 2022 to August 2023 were selected as research subjects.Using the random number table method,they were divided into a control group and an experimental group,each consisting of 72 cases.The control group received routine nursing intervention,while the experimental group received cognitive behavioral therapy based on standard nursing practices.The self-care ability(self-concept,self-efficacy,self-care skills,health knowledge level),coping style(confrontation,avoidance,and surrender),and quality of life(psychological function,social function,material life,physical function)of both groups before and after the intervention were compared.Results:In comparison to the pre-intervention period,the experimental group exhibited significantly higher self-care ability,quality of life,and confrontation scores after the intervention,as opposed to the control group.Additionally,the avoidance and surrender scores were lower in the experimental group than in the control group,with these differences proving to be statistically significant(P<0.01).Conclusion:The application of cognitive behavioral therapy can enhance the self-care ability of thyroid cancer patients,aid in better disease coping,and improve their overall quality of life.This approach is deserving of further promotion.
文摘Objective:To investigate the therapeutic effect of Biling Weitong Granules combined with oryz-aspergillus enzyme and pancreatin tablets on patients with reflux esophagitis with functional dyspepsia.Methods:Sixty patients diagnosed with reflux esophagitis with functional dyspepsia who were admitted to the Affiliated Hospital of Hebei University between June 2020 and June 2023 were selected and divided into two groups:the control group and the observation group,each consisting of 30 cases.The control group received oryz-aspergillus enzyme and pancreatin tablets only,while the observation group received Biling Weitong Granules in addition to the tablets.The clinical efficacy,Chinese medicine syndrome points,esophageal kinetic indexes,gastrointestinal hormone levels,and therapeutic safety of both groups were evaluated.Results:The total efficiency of the observation group reached 93.33%,significantly higher than the 73.33%of the control group(P<0.05).After treatment,patients in the observation group exhibited significantly lower scores for Chinese medicine symptoms such as early satiety,belching,abdominal distension,abdominal pain,and loss of appetite compared to the control group(P<0.05).Furthermore,the observation group showed significantly higher upper esophageal sphincter pressure,lower esophageal sphincter pressure,and distal esophageal contraction scores compared to the control group(P<0.05).Additionally,levels of gastric motility hormone,vasoactive intestinal peptide,and gastrin were significantly higher in the observation group compared to the control group(P<0.05).Throughout the treatment period,there was no significant difference in the incidence of adverse reactions between the two groups,indicating comparable safety of the two treatment modalities(P>0.05).Conclusion:The combination of Biling Weitong Granules with oryz-aspergillus enzyme and pancreatin tablets demonstrates significant efficacy in the treatment of reflux esophagitis with functional dyspepsia,with a better safety profile.This finding warrants further clinical promotion.

文摘Microglia-mediated inflammatory responses have been shown to play a crucial role in Parkinson’s disease. In addition, exosomes derived from mesenchymal stem cells have shown anti-inflammatory effects in the treatment of a variety of diseases. However, whether they can protect neurons in Parkinson’s disease by inhibiting microglia-mediated inflammatory responses is not yet known. In this study, exosomes were isolated from human umbilical cord mesenchymal stem cells and injected into a 6-hydroxydopamine-induced rat model of Parkinson’s disease. We found that the exosomes injected through the tail vein and lateral ventricle were absorbed by dopaminergic neurons and microglia on the affected side of the brain, where they repaired nigral-striatal dopamine system damage and inhibited microglial activation. Furthermore, in an in vitro cell model, pretreating lipopolysaccharide-stimulated BV2 cells with exosomes reduced interleukin-1β and interleukin-18 secretion, prevented the adoption of pyroptosis-associated morphology by BV2 cells, and increased the survival rate of SH-SY5Y cells. Potential targets for treatment with human umbilical cord mesenchymal stem cells and exosomes were further identified by high-throughput microRNA sequencing and protein spectrum sequencing. Our findings suggest that human umbilical cord mesenchymal stem cells and exosomes are a potential treatment for Parkinson’s disease, and that their neuroprotective effects may be mediated by inhibition of excessive microglial proliferation.
文摘Objective:To investigate the effect of psychological education combined with progressive muscle relaxation training on the symptom cluster and rehospitalization of elderly patients with coronary heart disease.Methods:This study is a longitudinal randomized controlled study involving 140 elderly patients with coronary heart disease.The patients were divided into two groups:an intervention group and a control group,with 70 cases in each group,via random number table.The patients in the control group received routine nursing,whereas those in the intervention group received psychological education combined with progressive muscle relaxation training for 4 weeks on the basis of routine nursing.The effect of the intervention was evaluated before intervention,at the end of 1 month,3 months,and 6 months after intervention.Results:At the end of 1 month,3 months,and 6 months,the sleep,fatigue,anxiety,and functional status of the patients in the intervention group were significantly better than those of the control group,with statistical significance difference(P<0.05).The rehospitalization rate of the intervention group was lower than that of the control group,and the difference was statistically significant(X2=10.685,P=0.001).Conclusion:Psychological education combined with progressive muscle relaxation training is effective in alleviating the symptom cluster of elderly patients with coronary heart disease and reducing their rehospitalization rate;thus,it should be popularized.
文摘Objective:To investigate the self-efficacy and mental health of elderly patients with coronary heart disease(CHD)in rural Hebei Province as well as to analyze the relationship between them.Methods:From June 2021 to December 2021,480 elderly patients with CHD from rural areas,who had been discharged by the Department of Cardiology from three tertiary hospitals in three cities with different economic levels in Hebei Province for more than a year,were selected as the research subjects.The general self-efficacy scale(GSES)and symptom self-rating scale(SCL-90)were used to investigate the self-efficacy and mental health of these patients.SPSS 25.0 was used for data analysis.Results:The total mean self-efficacy score of elderly patients with CHD in rural Hebei Province was 17.18±4.68,which is lower than the international norm(t=-32.067,P=0.000)and the national norm(t=-28.783,P=0.000);the total average SCL-90 score was 148.64±55.13,which is higher than the national norm for adults and the reference norm for ordinary elderly people;except for hostility and psychosis,the other dimensions were significantly higher than the national norm for adults(P<0.05);except for psychosis,the other dimensions were significantly higher than the reference norm for ordinary elderly people(P<0.05);the self-efficacy score was found to be negatively correlated with the total SCL-90 score and the score for each dimension(P<0.05).Conclusion:Elderly CHD patients with higher self-efficacy in rural Hebei Province have higher mental health level.It is suggested that the mental health of elderly patients with CHD in rural areas can be improved by improving their self-efficacy.

文摘Achieving accurate classification of colorectal polyps during colonoscopy can avoid unnecessary endoscopic biopsy or resection.This study aimed to develop a deep learning model that can automatically classify colorectal polyps histologically on white-light and narrow-band imaging(NBI)colonoscopy images based on World Health Organization(WHO)and Workgroup serrAted polypS and Polyposis(WASP)classification criteria for colorectal polyps.White-light and NBI colonoscopy images of colorectal polyps exhibiting pathological results were firstly collected and classified into four categories:conventional adenoma,hyperplastic polyp,sessile serrated adenoma/polyp(SSAP)and normal,among which conventional adenoma could be further divided into three sub-categories of tubular adenoma,villous adenoma and villioustublar adenoma,subsequently the images were re-classified into six categories.In this paper,we proposed a novel convolutional neural network termed Polyp-DedNet for the four-and six-category classification tasks of colorectal polyps.Based on the existing classification network ResNet50,Polyp-DedNet adopted dilated convolution to retain more high-dimensional spatial information and an Efficient Channel Attention(ECA)module to improve the classification performance further.To eliminate gridding artifacts caused by dilated convolutions,traditional convolutional layers were used instead of the max pooling layer,and two convolutional layers with progressively decreasing dilation were added at the end of the network.Due to the inevitable imbalance of medical image data,a regularization method DropBlock and a Class-Balanced(CB)Loss were performed to prevent network overfitting.Furthermore,the 5-fold cross-validation was adopted to estimate the performance of Polyp-DedNet for the multi-classification task of colorectal polyps.Mean accuracies of the proposed Polyp-DedNet for the four-and six-category classifications of colorectal polyps were 89.91%±0.92%and 85.13%±1.10%,respectively.The metrics of precision,recall and F1-score were also improved by 1%∼2%compared to the baseline ResNet50.The proposed Polyp-DedNet presented state-of-the-art performance for colorectal polyp classifying on white-light and NBI colonoscopy images,highlighting its considerable potential as an AI-assistant system for accurate colorectal polyp diagnosis in colonoscopy.

文摘Glioblastomas(GBMs)are the brain tumors with the highest malignancy and poorest prognoses.GBM is characterized by high heterogeneity and resistance to drug treatment.Organoids are 3-dimensional cultures that are constructed in vitro and comprise cell types highly similar to those in organs or tissues in vivo,thus simulating specific structures and physiological functions of organs.Organoids have been technically developed into an advanced ex vivo disease model used in basic and preclinical research on tumors.Brain organoids,which simulate the brain microenvironment while preserving tumor heterogeneity,have been used to predict patients’therapeutic responses to antitumor drugs,thus enabling a breakthrough in glioma research.GBM organoids provide an effective supplementary model that reflects human tumors’biological characteristics and functions in vitro more directly and accurately than traditional experimental models.Therefore,GBM organoids are widely applicable in disease mechanism research,drug development and screening,and glioma precision treatments.This review focuses on the development of various GBM organoid models and their applications in identifying new individualized therapies against drug-resistant GBM.
