RESUMO
BACKGROUND: There are relatively few studies on continuing care of coronary heart disease (CHD), and its research value needs to be further clarified. AIM: To investigate the effect of continuous nursing on treatment compliance and side effect management in patients with CHD. METHODS: This is a retrospective study with patients from January 2021 to 2023. The study was divided into two groups with 30 participants in each group. Self-rating anxiety scale (SAS) and Self-rating depression scale (SDS) were used to assess patients' anxiety and depression, and medical coping questionnaire was used to assess patients' coping styles. The pelvic floor dysfunction questionnaire (PFDI-20) was used to assess the status of pelvic floor function, including bladder symptoms, intestinal symptoms, and pelvic symptoms. RESULTS: SAS score decreased from 57.33 ± 3.01before treatment to 41.33 ± 3.42 after treatment, SDS score decreased from 50.40 ± 1.45 to 39.47 ± 1.57. The decrease of these two indexes was statistically significant (P < 0.05). PFDI-20 scores decreased from the mean 16.83 ± 1.72 before treatment to 10.47 ± 1.3the mean after treatment, which was statistically significant (P < 0.05). CONCLUSION: The results of this study indicate that pioneering research in continuous care of CHD has a positive impact on improving patients' treatment compliance, reducing anxiety and depression levels, and improving coping styles and pelvic floor functional status.
RESUMO
The C2 sulfonylation of quinoxalinones via a metal-free oxidative S-O cross-coupling strategy for synthesizing 2-sulfonyloxylated quinoxalines is established. It effectively solved the long-standing problems in the C2 transformation of quinoxalinones via a metal-free oxidative O-S coupling strategy. Compared with the traditional C2 transformed quinoxalinones-C2 chlorination method, this protocol is mild, facile, and environmentally friendly and exhibits good atomic economy and excellent functional group tolerance. Moreover, the utility of this methodology and the sulfonyloxyl handles was demonstrated through the synthesis of 2-substituted quinoxaline-based bioactive molecules.
RESUMO
To explore root architecture and its effects on soil reinforcement of main tree species in typical black soil region, we measured root spatial distribution characteristics, root fractal characte-ristics, and geometric morphological characteristics of Amygdalus triloba, Caragana microphylla, Betula platyphylla, Acer negundo, Picea koraiensis, Pinus sylvestris var. mongolica, using whole root excavation method and WinRHIZO Pro LA2004 root analysis system. All the examined species are distributed widely in typical black soil region. The vertical uprooting force was determined by in-situ uprooting tests. The results showed that inclined roots were dominant in A. triloba, horizontal roots were dominant in C. microphylla, B. platyphylla, A. negundo and P. koraiensis, and the horizontal and vertical distribution of roots were commensurable in P. sylvestris var. mongolica. Except for the total root surface area of B. platyphylla and the total root length of P. koraiensis, the total root length and root surface area of shrub species were significantly greater than those of arbor species, while deciduous broad-leaved trees were significantly larger than coniferous evergreen trees. The total root volume of B. platyphylla was significantly larger than that of C. microphylla, A. negundo, P. koraiensis and P. sylvestris var. mongolica. The root fractal dimension and abundance of A. triloba, C. microphylla, B. platyphylla were significantly higher than those of P. koraiensis and P. sylvestris var. mongolica. The average maximum uprooting force of A. triloba, C. microphylla, and A. negundo was significantly higher than that of B. platyphylla, P. koraiensis, and P. sylvestris var. mongolica. Due to the role of total root length, total root surface area and the number of inclined roots, root system of A. triloba, C. microphylla and A. negundo showed strong soil reinforcement capacity. A. triloba, C. microphylla and A. negundo could be used as the option-preferred tree species when constructing soil and water conservation vegetation in typical black soil region.
