This paper takes the Belt and Road Initiative for example,emphasizing the interpretation of the inheritance and development of Chinese culture so as to study the importance of Culture Self-Consciousness in Chinese Philosophy,in the context of English globalization. That is to say,this paper stresses the spirits and the stand of nation 's demonstration on pursuing peace,cooperation and sustainable development in the civilization continuity from traditional China to the contemporary China,with practical philosophic view.展开更多

But due to poor adherence, hypertension treatment outcomes often remain poor. Patient-centered educational interventions may reverse this trend. Using a pre-test/post-test design, in this study we investigated the effects of a structured cardiovascular health education program (CHEP) on treatment adherence, blood pressure (BP) control and body mass index (BMI) among Nigerian hypertensive patients who received guideline-based care in a rural primary care facility, in the context of a community based health insurance program. Study participants included 149 insured patients with uncontrolled BP and/or poor self-reported medication adherence after 12 months of guideline-based care. All patients received three group-based educational sessions and usual primary care over 6 months. We evaluated changes in self-reported adherence to prescribed medications and behavioral advice (primary outcomes);systolic BP (SBP) and/or diastolic BP (DBP) and BMI (secondary outcomes);and beliefs about hypertension and medications (explora- tory outcomes). Outcomes were analyzed with descriptive statistics and regression analysis. 140 patients completed the study (94%). At 6 months, more participants reported high adherence to medications and behavioral advice than at baseline: respectively, 101 (72%) versus 70 (50%), (p < 0.001) and 126 (90%) versus 106 (76%), (p < 0.001). Participants with controlled BP doubled from 34 (24%) to 65 (46%), (p = 0.001). The median SBP and DBP decreased from 129.0 to 122.0 mmHg, (p = 0.002) and from 80.0 to 73.5 mmHg, (p < 0.001), respectively. BMI did not change (p = 0.444). Improved medication adherence was associated with a decrease in medication concerns (p = 0.045) and improved medication self-efficacy (p < 0.001). By positively influencing patient perceptions of medications, CHEP strengthened medication adherence and, consequently, BP reduction among insured hypertensive Nigerians. This educational approach can support cardiovascular disease prevention programs for Africa’s growing hypertensive population.展开更多
