Objective To analyze the status quo of cognitive frailty (CF) in community elderly patients with chronic obstructive pulmonary disease (COPD) and its correlation with sleep quality, anxiety and depression. Methods Elderly patients with COPD receiving health management in the center were selected from July 2023 to June 2024. The general data of patients were collected and Mini-Mental State Examination (MMSE), Fried Frailty Phenotype (FP), Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety and Depression Scale (HADS) were used for investigation, and the above scores were analyzed. All patients were divided into CF group (n=129) and non-CF group (n=319) according to MMSE score and FP score. Univariate and multivariate logistic analyses were used to analyze the influencing factors of CF in elderly COPD patients. Results Pearson correlation analysis showed that MMSE score was significantly negatively correlated with PSQI score and HADS score in elderly COPD patients (P<0.05), and FP score was significantly positively correlated with PSQI score and HADS score (P<0.05). After logistic regression analysis, it was found that education level, marital status and sleep time were protective factors of CF in elderly COPD patients (P<0.05), and PSQI score and HADS score were risk factors of CF in elderly patients with COPD (P<0.05). Conclusion CF in community elderly COPD patients is related to sleep quality, sleep duration and anxiety and depression. It is necessary to take clinical measures to improve the sleep quality and psychological status, so as to avoid or slow down the occurrence of CF.

Objective:To analyze the relationship between aquaporin 1 (AQP1) level and vascular calcification in patients with diabetes nephropathy.Methods:A total of 125 diabetic nephropathy patients admitted to Suzhou Hospital of Nanjing Medical University from March 2020 to March 2023 were retrospectively selected as case group. The case group was divided into group A (diabetes nephropathy stage Ⅰ and Ⅱ) with 31 cases, group B (diabetes nephropathy stage Ⅲ) with 32 cases, group C (diabetes nephropathy stage Ⅳ) with 39 cases, and group D (diabetes nephropathy stage V) with 23 cases. In these patients, 51 cases had vascular calcification, taken as the calcification group, and 74 cases had no vascular calcification, taken as the non calcification group. Sixty volunteers who underwent health examinations in the same hospital were selected as the control group. Receiver operating characteristic curve was used to analyze the predictive value of AQP1 on vascular calcification in diabetes nephropathy patients and to explore the related factors of vascular calcification in diabetes nephropathy patients.Results:Compared with the control group, AQP1 level and calcification rate in groups A, B, C and D were higher: 6.41 ± 1.04, 7.93 ± 1.23, 9.50 ± 1.52 and 11.37 ± 2.01 vs. 3.83 ± 0.56 ng/L, 6.45% (2/31), 28.13% (9/32), 51.28% (20/29) and 86.96% (20/23) vs. 0 ( P<0.05). Compared with group A, the level of AQP1 and calcification rate in groups B, C and D were higher ( P<0.05); compared with group B, the AQP1 level and calcification rate in groups C and D were higher ( P<0.05); compared with group C, the level of AQP1 and calcification rate in group D were higher ( P<0.05). Compared to the non calcification group, the levels of uric acid, homocysteine and cystatin C in calcification group were higher: (313.82 ± 38.72) μmol/L vs. (253.42 ± 30.14) μmol/L, (20.03 ± 3.01) μmol/L vs. (15.01 ± 2.71) μmol/L, (1.73 ± 0.26) mg/L vs. (1.30 ± 0.17) mg/L ( P<0.05). AQP1 was positively correlated with uric acid, homocysteine, and cystatin C ( P<0.05). The area under the curve of AQP1, uric acid, homocysteine and cystatin C in predicting vascular calcification in patients with diabetes nephropathy were 0.892, 0.803, 0.738 and 0.763, respectively. Taking whether vascular calcification occurs in patients with diabetes nephropathy as the dependent variable (no = 0, yes = 1), the variables of P<0.05 in the single factor analysis were selected for multivariate Logistic regression analysis. The results showed that uric acid, homocysteine, cystatin C and AQP1 were the main factors affecting vascular calcification in patients with diabetes nephropathy ( P<0.05). Conclusions:Serum AQP1 has a high predictive value for vascular calcification in diabetes nephropathy patients, and is expected to be used as a biomarker for early diagnosis of vascular calcification in diabetes nephropathy patients.

Objective:To explore the hemodynamic and comfort effect of modified prone-flexed position in complexity renal calculi patients undergoing percutaneous nephrolithotomy.Methods:A total of 82 cases of complexity renal calculi patients who undergoing percutaneous nephrolithotomy were recruited and randomly assigned to experiment group (41 cases) and control group (41 cases). Patients in the control group were placed in conventional prone position, while in the experiment group were placed in modified prone-flexed position. The data include blood pressure, heart rate, respiratory rate, saturation of blood oxygen were recorded at preoprative, lithotomy position, change position 30 minutes after operation and postoperative. The General Comfort Questionnaire (GCQ) score was recorded in patients for postural comfort. The clinical data was also compared between two groups.Results:There was no significant difference in blood pressure, heart rate, respiratory rate, saturation of blood oxygen between experiment group and control group ( P>0.05). Compared to (44.95±4.80) min, 90.2% (37/41) of the control group, the patients in the experiment group was (47.80±6.71) min, 73.2% (30/41), which showed a shorter average operation time and higher total stone clearance rate, the differences were statically significant ( tvalue was 2.216, χ2value was 3.998, P<0.05). At immediately and 30 minutes after operation, the skin pressure were 9 cases and 4 cases in the experiment group, 18 cases and 11 cases in the control group, the differences were statically significant ( Zvalues were 2.132, 2.038, P<0.05). After 48 hours of surgery, the physical subscale and totl GCQ score were (13.32±1.40) and (78.56±4.65) pionts in the experiment group, significantly higher than (12.17±1.41), (75.76±5.16) pionts in the control group, the differences were statically significant ( tvalues were 3.685, 2.584, P<0.01 or 0.05). Conclusion:Modified prone-flexed position can shortern operation time decrease the risk of pressure injury and demonstrate better postural comfort of patients with complexity renal calculi undergoing percutaneous nephrolithotomy.

This study examined the adipocytokine-vascular interactions and link between epicardial adipose tissue and coronary artery atherosclerosis. Thirty-four patients undergoing open heart surgery were chosen randomly, and divided into group I (non-coronary artery disease group) and group II (coronary artery disease group). Blood samples were taken through peripheral vein prior to surgery. Plasma levels of a panel of proteins (adiponectin, IL-10, TNF-α) were detected by using ELISA. Epicardial adipose tissue was taken near the proximal tract of the right coronary artery and subcutaneous adipose was taken from the leg before cardiopulmonary bypassing, adiponectin and CD68 + were detected by using RT-PCR and immunohistochemistry. Our results showed that plasma adiponectin level was significantly lower in the group II as compared with group I (P<0.05). There were no differences in plasma concentration (IL-10, TNF-α, tatal-chol, HDL-chol, LDL-chol) between group I and group II. The number of CD68+ cells in epicardial adipose tissue of group II was significantly higher than that in subcutaneous adipose tissue. Adiponectin mRNA expression was 6 fold higher in subcutaneous adipose tissue than in epicardial adipose tissue of group II (P<0.01). Furthermore, the level of adiponectin mRNA in the epicardial adipose tissue in group II was also significantly lower than in group I (P<0.05). We are led to conclude that inflammation that occurs locally in epicardial adipose tissue of CAD contributes to the pathogenesis of coronary artery disease.
