Objective To investigate effect of continuous nursing care on compliance and adverse event in patients with coronary heart disease after PCI.Methods A total of 80 patients with coronary heart disease after PCI in our hospital were randomly divided into treatment group and control group, with 40 patients in each group, patients in the observation group implemented continuing nursing care, and the control group received routine care, quality of life score, treatment compliance and anxiety (SAS) and depression (SDS) score and adverse cardiac events and nursing satisfaction were compared.Results After nursing, physiological function, social function, emotional function, mental health, physiological function, vitality and general health scores in the observation group were higher, and body pain was lower than that in the control group (P<0.05);The observation group had lower anxiety (SAS) and depression (SDS) score, and higher compliance after nursing than the control group (P<0.05);The observation group had lower incidence of adverse cardiac events, and higher nursing satisfaction compared with the control group (P<0.05).Conclusion Continuing nursing can improve life quality, and compliance for patients with coronary heart disease after PCI, and it can reduce the anxiety, adverse and cardiac events, and improve nursing satisfaction, so it is worthy of clinical application.

Landfill is one of the important sources of carbon tetrachloride (CT) pollution, and it is important to understand the degradation mechanism of CT in landfill cover for better control. In this study, a simulated landfill cover system was set up, and the biotransformation mechanism of CT and the associated micro-ecology were investigated. The results showed that three stable functional zones along the depth, i.e., aerobic zone (0-15 cm), anoxic zone (15-45 cm) and anaerobic zone (> 45 cm), were generated because of long-term biological oxidation in landfill cover. There were significant differences in redox condition and microbial community structure in each zone, which provided microbial resources and favorable conditions for CT degradation. The results of biodegradation indicated that dechlorination of CT produced chloroform (CF), dichloromethane (DCM) and Cl^- in anaerobic and anoxic zones. The highest concentration of dechlorination products occurred at 30 cm, which were degraded rapidly in aerobic zone. In addition, CT degradation rate was 13.2-103.6 μg/(m²·d), which decreased with the increase of landfill gas flux. The analysis of diversity sequencing revealed that Mesorhizobium, Thiobacillus and Intrasporangium were potential CT-degraders in aerobic, anaerobic and anoxic zone, respectively. Moreover, six species of dechlorination bacteria and eighteen species of methanotrophs were also responsible for anaerobic transformation of CT and aerobic degradation of CF and DCM, respectively. Interestingly, anaerobic dechlorination and aerobic transformation occurred simultaneously in the anoxic zone in landfill cover. Furthermore, analysis of degradation mechanism suggested that generation of stable anaerobic-anoxic-aerobic zone by regulation was very important for the harmless removal of full halogenated hydrocarbon in vadose zone, and the increase of anoxic zone scale enhanced their removal. These results provide theoretical guidance for the removal of chlorinated pollutants in landfills.
