Objective: To explore the efficacy and safety of tertiary hospital guided and community-driven family self-help cardiac rehabilitation model. Methods: This study was a prospective randomized controlled study, 80 patients from Beijing Electrical Power Hospital and Beijing Jingmei Group General Hospital with acute coronary syndrome were included from June to December 2015 and divided into 2 groups. Patients in rehabilitation group (n=52) received tertiary hospital(Peiking University Peoples′ Hospital) guided and community-driven family self-help cardiac rehabilitation for 3 months, and patients in control group (n=28) received routine secondary treatment for 3 months. Following parameters including 6 minutes walk distance, score of life quality (evaluated by Short Form-12), score of anxiety (evaluated by Generalized Anxiety Disorder-7), score of depression (evaluated by Perceived Health Questionnaire-9), self-management competency (evaluated by questionnaire) were collected at baseline and after treatment for 3 months. Results: Compared with control group, 6 minutes walk distance was longer in rehabilitation group((60.2±6.8) meters vs. (24.9±10.5)meters, P<0.01). The difference values between after and before intervention of life quality scores((0.14±3.90)scores vs.(-7.44±5.85)scores, P>0.05), anxiety scores((-0.16±2.12 ) scores vs.(0.70±1.13)scores, P>0.05) and depression scores((-1.17±2.79) scores vs.(0.60±0.36)scores, P>0.05) were similar between the 2 groups. The amplification of patients with regular exercise (50.26% vs. 0, P<0.05), limit sugary foods usually and always (53.22% vs. 3.98%, P<0.05), eat 200-400 g fruits usually and always (78.61 % vs. 0, P<0.05), eat 300-500 g vegetables usually and always (9.74% vs. 0, P<0.05), and answering very confident to questions such as let the physicians know about your diseases (40.17% vs. 5.00%, P<0.05), know how to take medicines (44.52% vs. 5.00%, P<0.05), know how much exercise was right for yourself (26.43% vs.0, P<0.05) were significantly higher in rehabilitation group than in control group. There were no cardiac rehabilitation training related cardiovascular events. Conclusion Tertiary hospital guided and community-driven family self-help cardiac rehabilitation model is an effective and safe management model of cardiovascular disease in chronic phase, and it is necessary to further expand the study population to verify the efficacy of this model.

Objective:To assess the validity and reliability of the depression and somatic symptoms scale among patients with coronary heart disease.Methods:Totally 246 patients with coronary heart disease were assessed with depression and somatic symptoms scale (DSSS), Hamilton depression rating scale for depression (HAMD) and patients’ health questionnaire depression scale-9 item (PHQ-9). The structural validity was evaluated with exploratory factor analysis and confirmatory factor analysis. The validity as a screening tool was evaluated with the gold standard diagnosed by psychiatrists who were trained with the mini international neuropsychological interview (MINI) according to ICD-10. Receiver operating characteristic (ROC) curve was used to identify cutoff scores for depression. Cronbach α coefficient was used to evaluate the internal consistency.Results:Exploratory factor analysis yielded two factors: depression factor and somatic factor, and the cumulative variance was 51.8%. The fitting indexes of confirmatory factor analysis were as follows: χ2/ df=3.636, RMR=0.077, RMSEA=0.104, IFI=0.804, TLI=0.781, CFI=0.802. The intraclass correlation coefficient of DSSS and HAMD was 0.54. The area under ROC curve (AUC) was 0.828, and the best boundary value was 17 points (sensitivity and specificity: 81% and 75%, respectively). The total scores and subscale scores for internal consistency of DSSS were higher in the depression group than those in the non-depression group ( P<0.01). Cronbach α coefficient for internal consistency of DSSS was 0.917. Conclusion:The DSSS has good validity and reliability among patients with coronary heart disease for screening depression, and can be used to screen depression among patients with coronary heart disease in general hospital.

Objective To study the distribution and drug resistance of pathogens in patients with lung cancer,and analyze the prevention strategies. Methods A total of 312 cases of lung cancer patients with infection treated in our hospital from January 2017 to January 2021 were selected as the research objects.The lower respiratory tract secretions,urine and feces were collected for pathogen culture and drug sensitivity test;the distribution and drug resistance of pathogens were analyzed,and the corresponding prevention strategies were formulated. Results Of the 312 patients, 165 (52.88%) had respiratory tract infection, 79 (25.32%) had oropharyngeal infection, and 68 (21.80%) had urinary tract infection.The highest proportion was respiratory infection.Among the 312 patients,398 pathogens were detected of which 212 Gram-positive bacterias (53.27%)were found of which Staphylococcus epidermidis(15.58%)and Staphylococcus aureus(13.07%)accounted for a relatively high proportion. Among 175 Gram-negative strains,Klebsiella pneumoniae(15.94%)and E.coli (10.05% ) accounted for a large proportion.The resistance rate of Gram-positive bacteria,such as Staphylococcus epidermidis and Staphylococcus aureus,to amikacin,gentamicin and penicillin,was more than 50%,which was sensitive to vancomycin. Gram negative bacteria such as Klebsiella pneumoniae and E.coli have high resistance to common antibiotics,and the drug resistance rate to cefepime and cefazolin is more than 50%,and sensitive to imipenem/cilastatin and imipenem/cilastatin.Among 11 fungi,4 cases were resistant to fluconazole , 36.36%,3 to itraconazole,27.27%,0 to ketoconazole and voriconazole,0.00%. Conclusion The distribution and drug resistance of pathogenic bacteria in patients with lung cancer infection in our hospital have certain characteristics,in which Gram-positive bacteria are mainly Staphylococcus epidermidis and Staphylococcus aureus,Gram-negative bacteria are mainly Klebsiella pneumoniae and Escherichia coli,and there are also a small number of fungal infections.Therefore,we should strengthen the monitoring of etiology and drug resistance,and strengthen the management of hospital disinfection Drug sensitivity results of patients,rational use of antibiotics,so as to improve the treatment effect and reduce the risk of infection.
