Expression and clinical significance of PRKCD in liver hepatocellular carcinoma analyzed based on bioinformatics

Objective:To analyze the expression of protein kinase C delta(PKCδ,PRKCD)in Liver hepatocellular carcinoma and its clinical significance based on bioinformatics,in order to provide a new direction for the study of therapeutic targets for Liver hepatocellular carcinoma.Methods:The PRKCD gene expression data and patient clinical information data in Liver hepatocellular carcinoma tissues and adjacent tissues were downloaded from The TCGA(The Cancer Genome Atlas)and UCSC Xena databases.The mRNA expression of PRKCD in Liver hepatocellular carcinoma was analyzed,and the protein expression of PRKCD in Liver hepatocellular carcinoma was analyzed by Human Protein Atlas(HPA)databases.Furthermore,its relationship with clinicopathological features and prognosis in patients with Liver hepatocellular carcinoma was analyzed.GSEA enrichment analysis were carried out for PRKCD in Liver hepatocellular carcinoma.Finally,the causes of changes in PRKCD expression were analyzed from the perspective of genetic and epigenetics based on collated liver hepatocellular carcinoma data.Results:Both the mRNA and protein expression level of PRKCD gene in Liver hepatocellular carcinoma tissues was significantly higher than that in adjacent tissues.Its expression level was correlated with TNM stage,Histologic grade,Alpha fetoprotein(AFP)and Living status in clinicopathological features,and its expression level has certain clinical diagnostic accuracy.Kaplan-Meier analysis showed that the prognosis of patients with low PRKCD expression was significantly better than that with high PRKCD expression.Univariate and multivariate Cox regression analysis showed that PRKCD was an independent prognostic factor in patients with Liver hepatocellular carcinoma,and it was also found that the risk ratio of TNM stage III and stage IV survival curve(HR)was significantly greater than that of stage I and stage II.GSEA analysis showed that it was enriched in cell cycles and DNA replication,and was positively correlated with PRKCD.Enrichment analysis found that PRKCD is mainly involved in the chemokine signaling pathway,NOD-like receptor signaling pathway,PPAR signaling pathway,adipocytokine signaling pathway and T-cell receptor signaling pathway.Finally,through genetic and epigenetic analysis,it is found that the increase in the number of copies of genes will increase the expression level of PRKCD,and the methylation level is negatively correlated with the expression level of PRKCD.Conclusion:PRKCD gene is upregulated in Liver hepatocellular carcinoma tissues,and its overexpression level is closely related to patient poor prognosis.

Effect of teach-back health education combined with structured psychological nursing on adverse emotion and patient cooperation during 99mTc-3PRGD2.SPECT/CT

BACKGROUND 99mTc-3PRGD2.SPECT/CT is a commonly used examination method in nuclear medicine.However,patients receiving 99mTc-3PRGD2.SPECT/CT have insufficient knowledge of this method and worry about the examination results.AIM To investigate the effect of teach-back health education combined with structured psychological nursing on adverse emotion and cooperation in patients undergoing 99mTc-3PRGD2.SPECT/CT examination.METHODS Ninety patients undergoing 99mTc-3PRGD2.SPECT/CT examinations were divided into a study group and a control group using a simple random number table,and 45 cases were allocated to each group.Routine nursing was provided to the control group,and teach-back health education combined with structured psychological nursing was provided to the study group on the basis of the control group.Heart rate,diastolic blood pressure,systolic blood pressure,self-rating depression scale(SDS),and self-rating anxiety scale(SAS)were assessed before and after the intervention,and examination cooperation and intervention satisfaction were assessed in the two groups before,during,and after the examination.RESULTS Before the examination,heart rate,diastolic blood pressure,and systolic blood pressure in the study group were not significantly different from the values of the control group(P>0.05).The results of the study group before and after the examination were lower than those in the control group(P<0.05).Before the intervention,SDS and SAS scores in the study group were not significantly different from those in the control group(P>0.05).After the intervention,SDS and SAS scores in the study group were lower than those in the control group(P<0.05).The degree of cooperation was higher in the study group than in the control group(P<0.05).The satisfaction rate with the intervention was higher in the study group than in the control group(P<0.05).CONCLUSION Teach-back health education combined with structured psychological nursing can help maintain the stability of blood pressure and heart rate,relieve negative emotions,and improve the satisfaction and cooperation of patients undergoing 99mTc-3PRGD2.SPECT/CT examinations.
