ABSTRACT
BACKGROUND: Psychological factors such as anxiety and depression will not only aggravate the symptoms of chronic obstructive pulmonary disease (COPD) patients and reduce the quality of life of patients, but also affect the treatment effect and long-term prognosis. Therefore, it is of great significance to explore the clinical application of senile comprehensive assessment in the treatment of COPD and its influence on psychological factors such as anxiety and depression. AIM: To explore the clinical application of comprehensive geriatric assessment in COPD care and its impact on anxiety and depression in elderly patents. METHODS: In this retrospective study, 60 patients with COPD who were hospitalized in our hospital from 2019 to 2020 were randomly divided into two groups with 30 patients in each group. The control group was given routine nursing, and the observation group was given comprehensive assessment. Clinical symptoms, quality of life [COPD assessment test (CAT) score], anxiety and depression Hamilton Anxiety Rating Scale (HAMA) and Hamilton Depression Rating Scale (HAMD) were compared between the two groups. RESULTS: CAT scores in the observation group decreased from an average of 24.5 points at admission to an average of 18.3 points at discharge, and in the control group from an average of 24.7 points at admission to an average of 18.3 points at discharge. The average score was 22.1 (P < 0.05). In the observation group, HAMA scores decreased from 14.2 points at admission to 8.6 points at discharge, and HAMD scores decreased from 13.8 points at admission to 7.4 points at discharge. The mean HAMD scores in the control group decreased from an average of 14.5 at admission to an average of 12.3 at discharge, and from an average of 14.1 at admission to an average of 11.8 at discharge. CONCLUSION: The application of comprehensive geriatric assessment in COPD care has a significant effect on improving patients' clinical symptoms and quality of life, and can effectively reduce patients' anxiety and depression.
ABSTRACT
Changes in immune responses to hepatocellular carcinoma (HCC) are closely related to the occurrence, development, and prognosis of this disease. Exploring the role of immune-related genes (IRGs) in HCC would provide insights into the mechanisms regulating this disease. The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) provide a platform for such research, owing to a large number of HCC samples available for comprehensive and systematic immunogenomics analyses. We analyzed the IRGs expression profile and clinical information of patients with HCC based on the TCGA and ICGC database. Potential molecular mechanisms and properties of the screened IRGs were analyzed across multiple databases. And we analyzed the correlation between IRGs, single-nucleotide polymorphisms, and copy number variation. A novel prognostic index, based on IRGs, was developed using the LASSO Cox regression algorithm, followed by univariate and multivariate Cox regression analyses to analyze the prognostic index. Information in the ICGC database was used to verify the reliability of the prognostic index. A total of 54 differentially expressed IRGs were found to be significantly associated with HCC prognosis, and there is a significant correlation between their expression level and copy number variation. Functional enrichment analyses indicated that the genes play active roles in tumor and immune-related signaling pathways. In addition, five potential biomarkers namely IRG, MAPK3, HSP90AA1, HSP90AB1, HSPA4, and CDK4, were identified. Finally, a novel prognostic index, based on IRGs (PSMD14, FABP6, ISG20L2, HGF, BIRC5, IL17D, and STC2), was found useful as an independent prognostic factor, not only for prognosis but also to reflect levels of infiltration in a variety of immune cells. Our team conducted a genomics study of IRGs in HCC and screened several clinically significant IRGs, and our model provides an effective approach for stratification and characterization of patients using IRG-based immunolabeling tools to monitor the prognosis of HCC.

The present study examined the effects of anatase nanometer TiO2 on photochemical degradation of chlorothalonil in aqueous solution and on the plant surface. Results showed that nanometer TiO2 exhibited a strong photosensitizing effect on the degradation of chlorothalonil both in aqueous solution and on the surface of green pepper. The photosensitization rate was the highest in the sunlight compared to illumination under high-pressure mercury and UV lamps. Use of distinct hydroxyl radical scavengers indicated that nanometer TiO2 acted by producing hydroxyl radicals with strong oxidizing capacity. Notably, nanometer TiO2 facilitated complete photodegradation of chlorothalonil with no detectable accumulation of the intermediate chlorothalonil-4-hydroxy. Nanometer TiO2 was also active on the surface of green pepper under natural sunlight both inside and outside of plastic greenhouse. These results together suggest that nanometer TiO2 can be used as a photosensitizer to accelerate degradation of the pesticides under greenhouse conditions.
