ABSTRACT
Objective:To investigate the effects of pulmonary rehabilitation on anxiety/depression and subjective/objective sleep quality of elderly patients with stable chronic obstructive pulmonary disease(COPD).Methods:From February 2018 to February 2019, 120 elderly patients with stable COPD were selected and randomly divided into the experimental group (pulmonary rehabilitation exercise combined with conventional COPD treatment) and the control group (simple COPD conventional treatment). Sixty cases in each group were intervened for 8 weeks. Before and after treatment, Hamilton anxiety scale (HAMA) was used to evaluate anxiety, Hamilton depression scale(HAMD)was used to evaluate depression, Pittsburgh sleep quality index(PSQI)and sleep log were used to evaluate subjective sleep quality, and objective sleep quality was monitored by multi-channel sleep monitor.SPSS 21.0 software was used to analyze and process the data. Chi square test, independent sample t test and paired t test were used for statistical analysis. Results:After 8 weeks of intervention, the HAMA and HAMD scores of the experimental group were lower than those of the control group (HAMA: (7.57±3.19) vs (10.15±4.89), t=-3.428, P=0.001; HAMD: (8.22±4.73) vs (10.60±6.49), t=-2.300, P=0.023). COPD patients with anxiety decreased (χ 2=7.566, P=0.006). After treatment, the subjective sleep latency of the experimental group was shorter than that of the control group ((42.00±9.88)min vs (47.25±10.27)min, t=-2.854, P=0.005). The subjective sleep efficiency was higher than that of the control group ((76.00±4.50)% vs (74.00±5.20)%, t=2.272, P=0.025), and the objective sleep latency was shorter than that of the control group ((28.02±5.59)min vs (32.95±6.21)min, t=-4.575, P<0.05). Conclusion:Pulmonary rehabilitation exercise can improve the anxiety and depression of elderly patients with stable COPD, and improve the subjective and objective sleep quality.
ABSTRACT
Objective To investigate the relationship between proinflammatory cytokines and cognitive function in patients with mild cognitive impairment (MCI).Methods From May 2007 to May 2009,70 patients (aged ≥ 60 years) with MCI were collected.Among them,50 cases were amnestic MCI,and 19 cases developed into AD.The cognitive function was assessed,and all patients were followed up.The venous blood samples were obtained and proinflammatory cytokines (IL-1α,IL 1β,IL-6,TNF-α) were detected by using enzyme linked immunosorbent assay.Results There were differences in the levels of proinflammatory cytokines between patients with aMCI and patients with Alzheimer's disease (AD) [IL-1β,(40.5 ± 7.7) μg/L vs.(38.6 ± 7.3) μg/L ; IL 6,(70.4 ±24.3) μg/'L vs.(53.6±20.5) μg/L;TNF-α,(58.6±13.5) μg/'L vs.(50.3±-17.1) μg/'L;t=3.537,2.229,2.226,P=0.002,0.039,0.039,respectively].Conclusions MCI is a preclinical state of AD.The cognitive function damage of MCI patients are different from that of AD patients,and the immune status of MCI patients is also changed.
ABSTRACT
ObjectiveTo explore the effects of insomnia on heart rate variety(HRV) in aged hypertension patients. Methods259 subjects were divided into healthy group (74 cases),simple hypertension group (71 cases),coexisting hypertension and insomnia group (114 cases) which was sub-grouped to ＜5 years,5-9 years and ≥-10 years according to the duration of insomnia.All subjects had 24 h recordings of ECG.The data of HRV time domain (SDNN,SDANN and ASDNN) were collected and compared.ResultsHRV time domain was lower in healthy group than in the other two groups (F=12.02,10.54 and 4.27,P＜0.01),and decreased more significantly in coexisting hypertension and insomnia group compared with simple hypertension group(P＜0.01).The values of SDNN and SDANN in 5-9 years and ≥ 10 years subgroups decreased as compared with ＜ 5 years subgroup (F=8.63 and 4.54,P＜0.01),and these values further lower in ≥10 years subgroup than in 5-9 years subgroup (P＜ 0.01 ). ConclusionsInsomnia may lead to more serious disorder of automatic nervous system and further aggravated disorders appear in the elderly with hypertension along with increasing years of insomnia.
ABSTRACT
Objective To investigate behavioral and endocrinal changes following the conflict-related stress. Method Male SpragueDawley rats were exposed to stressors using Vogel conflict test. Body weight and behavioral responses in open field test were investigated during the whole procedure. Serum corticosterone level was analyzed using immunoassay. Results Compared with the control, the rats of the 1-week, 2-week and 4-week stressed group showed significantly decreased body weight. There was increasing tendency or significant difference in locomotion between the 1 -week, 2-week and 4-week stressed group and their control. And the hormone levels for the stressed animal were reliably high. Conclusions The increased locomotion, and high corticosterone level and reduced body weight in stress animal,was consistent with the features of anxiety-like disorders. Furthermore, the behavioral and endocrine changes produced by conflict-related stress could maintain a long time. The conflictrelated stress paradigm may be used as psychological stress animal mode in the future.
