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 explore the effect of diversified and teamwork health education mode on disease-related knowledge of coronary artery disease patients.Methods 147 cases of patients with coronary artery disease hospitalized in the general hospital of Tianjin medical university were divided into the treatment group which was given diversified health education of teamwork mode and the control group which was given traditional health education.The self-designed questionnaire was used to evaluate the effect of teamwork health education mode.Results Level of knowledge in the treatment group was significantly improved when compared with the control group,the increase amplitude of knowledge level in the treatment group was higher than the control group,and the scores of the treatment group were higher than the control group in the dimensions of diet,prevention,clinical manifestation,treatment,activity,the differences were statistically significant.Conclusions With diversified,multidisciplinary,and teamwork health education mode the patients' level of knowledge was significantly improved,the correct and positive awareness about disease were increased,and the patients were urged to take healthy behavior,so that their physical and mental state will maintain the best.

Objective To explore the influence of uncertainty in illness in compliance of respiratory function exer-cise and rehabilitation after surgery in patients with coronary artery bypass graft (CABG) surgery. Methods Mishel uncer-tainty in illness scale and compliance of respiratory function exercise scale were used to collect data in 108 patients with CABG. The correlation of the uncertainty in illness and compliance of respiratory function exercise was analyzed. Patients were divided into three groups (high score, medium score and low score groups) according to the detection of uncertainty in illness. Values of compliance of respiratory function exercise, postoperative care time, postoperative ventilation time, postop-erative hospital stay duration, 6-min walking test (6MWD) and left ventricular ejection fraction (LVEF) were compared be-tween three groups. Results The uncertainty in illness was in medium level (95.51±9.48) in patients with CABG surgery, which was negatively correlated with compliance of respiratory function exercise (r=-0.926, P<0.01). The postoperative venti-lation time and postoperative care time were less in low score group than those of medium score group and high score group. The compliance of respiratory function exercise, 6-min walking test and postoperative LVEF were better in low score group than those of medium score group and high score group. Conclusion Medical personnel should take targeted interventions to reduce the uncertainty in illness in patients, enhance the compliance of respiratory function exercise, reduce the postopera-tive complications and promote early recovery of patients.

Objective:We conducted a real-world multi-center clinical study with a large sample size to comprehensively evaluate the performance of three commercial hepatitis C virus (HCV) core antigen assays. The study aimed to evaluate the performance for their use in HCV infection screening, and to provide clues for further improving the sensitivity and specificity of the assays.Methods:Key performance indicators including the lower limit of detection (LOD), diagnostic sensitivity, and specificity of three HCV antigen assays (the Architect, Laibo, and ChemClin HCV core antigen assays) were evaluated using commercial seroconversion panels reflecting early HCV infection and clinical routine serum samples of outpatients and inpatients from 3 tertiary hospitals from January 2018 to April 2022. Factors that affect the performance indicators were further investigated.Results:The window period for detecting HCV infection with the three antigen assays was equal to or slightly longer than that of the RNA assay, but all are shorter than that of the anti-HCV assay. There was a good linear positive correlation between HCV core antigen and HCV RNA levels in treatment naive patients with hepatitis C ( r=0.90, P<0.01). For the most common genotype 1b strain in China, the LOD of the three HCV assays were equivalent to 531 IU/ml (Architect), 3,698 IU/mL (Laibo), and 4,624 IU/mL (ChemClin) HCV RNA, respectively. Due to the skewed distribution of HCV RNA levels in treatment-naive hepatitis C patients, more than 95% of the patients had viral loads higher than 6 166 IU/ml. Therefore, the three HCV antigens assays still maintained a satisfactory diagnostic sensitivity (94.33%-99.40%). Among 54 immunodeficient patients (leukemia patients) with HCV infection, 9% (5/54) had negative anti-HCV results, while the HCV antigen assays found all these infectors. Through further experiments, we revealed the amino acid polymorphism in the core region of genotype 3 strain impaired the sensitivity of all three HCV antigen assays. In addition, the sensitivity of the two domestic assays was impaired by anti-HCV antibodies in the serum. The specificity of HCV antigen assays for diagnosing hepatitis C is 99.94% to 99.98%. The rheumatoid factors, autoantibodies, and other unknown interference substances can lead to a small number of low level, "false positive" antigen results. Conclusions:HCV core antigen assay may be used as a satisfactory approach of infection screening, especially for the immunodeficient patents. However, the sensitivity and specificity of the assays are influenced by multiple factors, which should be further improved.
