Objective To explore the influence of social support on compliance of respiratory function exercise and rehabilitation in patients with coronary artery bypass graft surgery. Methods A total of 102 patients with coronary artery bypass graft surgery were evaluated by General Data Survey Scale,Social Support Questionnaire and Compliance of Respiratory Function Exercise Scale.According to the situation of patients′social support, patients were divided into high score group,medium score group and low score group, then compliance of respiratory function exercise,postoperative ICU stay time, postoperative ventilation time, postoperative hospital stay, 6-min walking test (6MWD) and left ventricular ejection fraction (LVEF) were compared among three groups. Results The social support of patients with coronary artery bypass graft surgery in medium level,the score was (34.70 ±7.46) points. The postoperative ventilation time, postoperative ICU stay time in high score group were less than those in medium score group and low score group:(17.79±5.30) h vs. (42.41±14.18), (80.00±11.15) h, (24.29±6.00) h vs. (55.66±16.31), (92.46±10.21) h, and there were significant differences, F=47.340,110.252,P<0.01. The compliance of respiratory function exercise,6MWD and LVEF in high score group were better than those in medium score group and low score group:(38.93±24.37) points vs.(30.26±4.79), (19.85±4.45) points, (376.07±55.92) m vs. (328.83±59.27), (302.04±60.24) m, (60±4)%vs. (53±9)%, (51±10)%, and there were significant differences, F=286.040, 55.228, 20.159,P < 0.01. Conclusions Social support can improve the patients′adherence to treatment, and enhance the patients′ability to cope with stressful events,then accelerate the process of postoperative rehabilitation of patients effectively,and improve quality of life.

Objective To evaluate the clinical efficacy of tissue-type plasminogen activator (tPA) treatment of children with plastic bronchitis.Methods The study retrospectively reviewed the clinical data of the children with plastic bronchitis who were admitted to Tianjin Children's Hospital from September 2013 to January 2015 and were treated with tissue-type plasminogen activator.This study analyzed the effect and safety of tPA treatment,including clinical and radiological changes and follow-ups.Results A lot of plastic secretions were safely removed from the bronchial tubes in all children and clinical manifestations including breathing,body temperature,transcutaneous oxygen saturation and image changes were significantly improved.Conclusions Bronchoscopy is an effective way to treat plastic bronchitis,but with the use of tPA a better clinical efficacy could be achieved.The method is safe and effective and should be applied early in the patients in order to prevent the occurrence of severe airway obstruction complications.

Objective To investigate the effects of phased written health education in heart stent surgery patients. Methods A total of 200 cases with heart stent surgery were randomly divided into two groups based on the random number table, 100 cases in each group. The patients of control group used conventional methods of coronary stent nursing care, while the patients of observation group received a phased written health education on the basis of routine care. We contrasted compliance behavior in the two groups of patients, as well as side effects, and treatment satisfaction. Results The compliance behavior of observation group were significantly better than that of the control group (P<0. 05). The incidence of adverse reactions in the patients of observation group was significantly lower than that of the control group (P<0. 05). Similarly, the satisfaction of observation group were better than that in the control group (P<0. 05). Conclusions Phased written health education is an effective health education, which can enhance compliance behavior and patient′s satisfaction with care.

Background Chronic excessive exposure to fluoride can cause damage to the central nervous system and a certain degree of learning and memory impairment. However, the associated mechanism is not yet clear and further exploration is needed. Objective Using 4D unlabelled quantitative proteomics techniques to explore differentially expressed proteins and their potential mechanisms of action in chronic excessive fluoride exposure induced brain injury. Methods Twenty-four SPF-grade adult SD rats, half male and half male, were selected and divided into a control group and a fluoride group by random number table method, with 12 rats in each group. Among them, the control group drank tap water (fluorine content<1 mg·L⁻¹), the fluoride group drank sodium fluoride solution (fluorine content 10 mg·L⁻¹), and both groups were fed with ordinary mouse feed (fluoride content<0.6 mg·kg⁻¹). After 180 d of feeding, the SD rats were weighed, and then part of the brain tissue was sampled for pathological examination by hematoxylin-eosin (HE) staining and Nissl staining. The rest of the brain tissue was frozen and stored at −80 ℃. Three brain tissue samples from each group were randomly selected for proteomics detection. Differentially expressed proteins were screened and subcellular localization analysis was performed, followed by Gene Ontology (GO) function analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, cluster analysis, and protein-protein interaction analysis. Finally, Western blotting was used to detect the expression levels of key proteins extracted from the brain tissue samples. Results After 180 d of feeding, the average weight of the rats in the fluoride group was significantly lower than that in the control group (P<0.05). The brain tissue stained with HE showed no significant morphological changes in the cerebral cortex of the fluoride treated rats, and neuron loss, irregular arrangement of neurons, eosinophilic changes, and cell body pyknosis were observed in the hippocampus. The Nissl staining results showed that the staining of neurons in the cerebral cortex and hippocampus of rats exposed to fluoride decreased (Nissl bodies decreased). The proteomics results showed that a total of 6927 proteins were identified. After screening, 206 differentially expressed proteins were obtained between the control group and the fluoride group, including 96 up-regulated proteins and 110 down-regulated proteins. The differential proteins were mainly located in cytoplasm (30.6%), nucleus (27.2%), mitochondria (13.6%), plasma membrane (13.6%), and extracellular domain (11.7%). The GO analysis results showed that differentially expressed proteins mainly participated in biological processes such as iron ion transport, regulation of dopamine neuron differentiation, and negative regulation of respiratory burst in inflammatory response, exercised molecular functions such as ferrous binding, iron oxidase activity, and cytokine activity, and were located in the smooth endoplasmic reticulum membrane, fixed components of the membrane, chloride channel complexes, and other cellular components. The KEGG significantly enriched pathways included biosynthesis of secondary metabolites, carbon metabolism, and microbial metabolism in diverse environments. The results of differential protein-protein interaction analysis showed that the highest connectivity was found in glucose-6-phosphate isomerase (Gpi). The expression level of Gpi in the brain tissue of the rats in the fluoride group was lower than that in the control group by Western blotting (P<0.05). Conclusion Multiple differentially expressed proteins are present in the brain tissue of rats with chronic fluorosis, and their functions are related to biosynthesis of secondary metabolites, carbon metabolism, and microbial metabolism in diverse environments; Gpi may be involved in cerebral neurological damage caused by chronic overdose fluoride exposure.
