Objective To investigate the impact of peritoneal albumin leakage on malnutrition-inflammation-atherosclerosis (MIA) syndrome in continuous ambulatory peritoneal dialysis (CAPD) patients. Methods A cross-sectional study of a cohort of 130 CAPD patients without edema or active infection was performed. In order to identify peritoneal transport characteristics in CAPD patients, a standard peritoneal equilibration test (PET) was carried out. For malnutrition and inflammation, serum albumin and high-sensitivity C-reactive protein (hs-CRP) levels were measured. Mean-carotid artery intima media thickness (IMT) was used to determine atherosclerosis. Residual glomerular filtration rate (rGFR) was defined as the average of 24-hour urinary urea and creatinine clearances. Results Pearson and Spearman correlation analysis showed that peritoneal albumin leakage amount was positively correlated with age, body mass index, night dwell time, blood glucose, 4 h D/P creatinine levels and hs-CRP levels (r=0.204, P<0.05 ;r=0.314, P<0.01; r=0.265, P<0.01; r=0.212, P<0.05; r=0.401, P<0.01; r=0.216, P<0.05); whereas it was negatively correlated with diastolic perssure, serum albumin levels, glucose level of dialyzate and peritoneal Kt/V (r=-0.209, P<0.05; r=-0.123, P<0.05; r=-0.271, P<0.01; r=-0.212, P<0.01). Overall, there was no correlation between peritoneal albumin leakage and IMT. Patients was significantly greater (P<0.01), and there was a positive correlation between peritoneal albumin leakage amount and IMT (r=0.650, P<0.01). Conclusions Peritoneal albumin leakage is significantly associated with peritoneal transport characteristics, malnutrition and inflammatory state in CAPD patients. High peritoneal albumin leakage amount is a risk factor for atherosclerosis in patients with rGFR less than 1 ml·min-1(1.73 m2)-1.

Objective:To clarify the influence and influence paths of stigma on the time of the healthcare-seeking decision in caregivers of elderly patients with dementia, and to provide a theoretical basis for the construction of corresponding humanistic care strategies.Methods:A total of 176 caregivers of elderly patients with dementia who visited the Affiliated Hospital of Xuzhou Medical University and Xuzhou Oriental People ′s Hospital from February 2021 to February 2022 were selected as the study subjects. The General Information Questionnaire, self-designed Scale of Stigma for Caregivers of Senile dementia patients, Multidimensional Scale of Perceived Social Support, self-designed Elderly Dementia Caregivers′ Perceived Barriers Scale for Healthcare-seeking Decision, and self-designed Scale of the Intention to Seek Healthcare for caregivers of senile dementia patients were used in the survey. AMOS 20.0 was used to establish a structural equation model for path analysis. Results:The higher the stigma of caregivers, the longer the time of the healthcare-seeking decision ( β=0.05, P<0.05). Social support, perceived barriers to the healthcare-seeking decision, and the intention to seek healthcare were the mediating variables of caregivers ′ stigma affecting the time of the healthcare-seeking decision, with a total effect of -0.04, 0.14, and 0.36, respectively, and all P<0.05. Conclusions:The stigma in caregivers of senile dementia patients is an important factor affecting the time of the healthcare-seeking decision. By improving mediating factors including social support, perceived barriers to the healthcare-seeking decision, and the intention to seek healthcare, the implementations of targeted humanistic care strategies are expected to help shorten the time of the healthcare-seeking decision.

Objective: To observe the effects of electroacupuncture (EA) at Neiguan (PC6) on arrhythmia during acute myocardial ischemia-reperfusion and the expression of connexin 43 (Cx43) in rats. Methods: A total of 40 Sprague-Dawley male rats were used. Ten rats were randomly selected as the blank group, and the remaining 30 rats were randomly divided into a model group and an EA group, with 15 rats in each group. Before modeling, rats in the EA group received one session of EA intervention at bilateral Neiguan (PC6) for 30 min; the other groups were treated with the same grasping and anesthesia for 30 min without intervention. PowerLab physiological recorder was used to record electrocardiograph within 30 min of infarction. After the experiment, cardiac tissue and serum were collected from rats. Hematoxylin-eosin (HE) staining was used to observe the morphological changes of myocardial tissue in the ventricular infarction area of rats in each group. The expression of Cx43 protein in the myocardium of each group was detected by Western blotting (WB). Enzyme-linked immunosorbent assay (ELISA) was used to determine the activity of Na+-K+-ATPase in myocardial tissue and the serum content of endogenous digitalis-like factor (EDLF) in rats. Results: There was no statistical difference in arrhythmia score between the EA group and the model group, but the total duration and average duration of arrhythmia in the EA group were decreased (P<0.01). HE staining showed that compared with the blank group, myocardial cells in the model group were disorganized and seriously damaged. The pathological changes in the EA group were similar to those in the model group, but the damage was relatively minor. The results of WB showed that compared with the blank group, the Cx43 expression in myocardial tissue of the model group was decreased (P<0.01); compared with the model group, the Cx43 expression in the EA group was increased (P<0.01); compared with the blank group, the Na+-K+-ATPase activity in myocardial tissue of the model group was significantly decreased (P<0.01); compared with the model group, the Na+-K+-ATPase activity in the EA group was increased (P<0.01). ELISA results showed that compared with the blank group, the serum EDLF content in the model group was significantly increased (P<0.01); compared with the model group, the EDLF content in the EA group was decreased (P<0.01). Conclusion: EA at Neiguan (PC6) can delay and reduce the onset of arrhythmia during myocardial infarction in the rat model of myocardial ischemia-reperfusion. Its mechanism of action may be related to the regulation of the Cx43 expression in myocardial tissue, improvement of the activity of Na+-K+-ATPase in myocardial tissue, and increase in the content of serum EDLF.
