Abstract:
Objective To explore the evaluation value of serum follistatin like protein 1(FSTL1)and glu-cose regulatory protein 78(GRP78)on disease severity and readmission in elderly patients with chronic ob-structive pulmonary disease(COPD).Methods A total of 100 elderly COPD patients(COPD group)treated in this hospital from March 2020 to May 2023 were selected as COPD group,and were divided into grade Ⅰ(35 cases),grade Ⅱ(46 cases)and grade Ⅲ(19 cases)according to the severity of the disease.Another 100 elderly volunteers who underwent physical examination during the same period were selected as the control group.Serum FSTL1 and GRP78 levels were detected by enzyme-linked immunosorbent assay(ELISA).Spearman and Pearson correlation were used to analyze the correlation between serum FSTL1 and GRP78 lev-els and general data.The evaluation value of serum FSTL1 and GRP78 levels in COPD patients on disease se-verity and readmission was analyzed by receiver operating characteristics(ROC)curve.Results Compared with the control group,serum levels of FSTL1 and GRP78 in COPD group were significantly increased(P＜0.05).Serum levels of FSTL1 and GRP78 in COPD patients increased with the severity of the disease(P＜0.05).Compared with non-readmission group,the serum levels of FSTL1 and GRP78 in readmission group were significantly increased(P＜0.05).Spearman correlation analysis showed that serum FSTL1 and GRP78 levels were positively correlated with smoking history,hypertension history and disease severity(P＜0.05).Pearson correlation analysis showed that serum FSTL1 and GRP78 levels were negatively correlated with arte-rial oxygen pressure(PaO2),the ratio of forced expiratory volume in the first second to forced vital capacity(FEV1/FVC),and the percentage of forced expiratory volume in the first second to expected value(FEV1％pred),with significance(P＜0.05),while it was positively correlated with the partial pressure of carbon diox-ide(PaCO2),with significance(P＜0.05).ROC curve analysis showed that serum FSTL1,GRP78 and their combined assessment of disease severity and readmitted area under the curve(AUC)were higher in COPD pa-tients,and the combination was significantly better than the single assessment(P＜0.05).Conclusion Serum levels of FSTL1 and GRP78 are significantly increased in COPD patients,which are correlated with the severi-ty of the disease and have a high value in evaluating the severity of the disease and readmission.
