The worldwide shortage in the supply of donor organs and tissues is becoming more pronounced. Xenotransplantation may probably give the hope to overcome the problem ultimately. However, it gives rise to a number of social and ethical issues, among them, the pig appears to be a likely source for human transplantation because it entails least social and ethical issues than no-human primates or other animals and the pig is similar to human in many aspects. The ethical and economic aspects must also be taken into consideration. Patient and his family’s privacy may be stripped because the patient has received a new or unusual treatment. Xenograftings will squint towards a kind of commodities which are different from human graftings and it is a challenge to human transplantation. Xenotransplantation brings a risk of creating new human disease and pandemic, so, it is necessary to formulate a policy and provide input to draft guidelines on the regulation of xenotransplantation.
The social needs, disciplinary development and humanistic reflection has promoted the emergence and development of evidence-based medicine. Moreover, evidence-based medicine-problems oriented research, evidence based decision, transferring results to practice and outcome evaluation-continues to meet society demands, promote the development of discipline and show humanist concern. The application of evidence-based medicine has gradually extended from the field of clinical medicine to the public health, society, management, economy, policy research and education in the process of solving various problems. The high quality evidence has also been important to decision-making in these fields. Our study explored the emergence and development of evidence-based medicine from the perspective of social needs, disciplinary development and humanistic reflection for the first time.
ObjectiveTo explore the level of hope of patients with tumor recurrence and its affecting factors. MethodsPatients with tumor recurrence admitted in West China Hospital from March 2014 to March 2015 were included in this study. Questionnaire survey was conducted to collect the general information of the patients and the information on their coping style, level of hope and social support. The structural equation model was used to analyze the factors that affect the level of hope in patients with tumor recurrence. ResultsA total of 431 patients were included. The average score of hope in patients with tumor recurrence was 32.88±5.83. Among these patients, 27 (6.26%) had low level of hope, 277 (64.27%) had medium level of hope and 127 (29.47%) had high level of hope. The result of univariate analysis showed that, the level of hope in different genders, marital status, education levels, income levels and types of tumors had significant differences (all P values＜0.05). The result of structural equation model showed that gender (r=-0.322, P<0.001), marital status (r=-0.243, P<0.001), education level (r=-0.219, P<0.001), income (r=0.116, P=0.021) and coping style (r=0.182, P=0.029) had direct effect on the level of hope in patients with tumor recurrence. Social support (r=0.255, P=0.027) and income (r=0.224, P=0.019) could indirectly affect patients’ coping style and therefore the level of hope. ConclusionMost patients with tumor recurrence have medium to high level of hope. Gender, marital status, education level, income and coping style have influence on the level of hope. More attention should be given to patients with low level of hope, and measures should be taken to improve the level of hope basing on the individual situations of patients with tumor recurrence.
ObjectiveTo explore the relationship between the natural environment of residential areas and subjective well-being of the elderly and the role of the elderly’s evaluation of the environmental protection work in both. MethodsBased on the China social survey database (CSS) in 2019, Rstudio and Stata software were used to process the data screened according to the restricted conditions, and multi-classification logistic regression analysis and Bootstrap mediation effect test were used to test the effect relationship among variables. ResultsAir pollution, water pollution, noise pollution, land pollution, electromagnetic ionizing radiation pollution and other pollution in residential areas have no direct effect on the subjective well-being of the elderly (P>0.05). The evaluation of the elderly on the environmental protection work had a positive impact on the elderly’s subjective well-being (P<0.01) and played a completely mediating role in the impact of the natural environment in the residential area on the elderly’s subjective well-being. ConclusionThe government should continue to play a leading role in coordinating environmental protection and pollution control work. In addition, establish an open and transparent environmental protection information disclosure system and strengthen communication with the elderly.
There is a great hope to treat long bone defects with bioactive artificial bone constructed by osteoblasts and biomaterials, in which the key point is to provide an optimum environment for the normal function of osteoblasts. The cellular sociological characteristics of osteoblasts were summarized and it was suggested that the ideal bioactive artificial bone should be composed of inorganic and organic materials together with cellular components such as osteoblasts and vascular endothelial cells, and combined with control release of growth factors, following its implantation it could be vascularized very soon and merged with the host bone by bony consolidation.
Objective To analyze the causal relationship between educational attainment and the risk of systemic lupus erythematosus (SLE). Methods Based on the data from publicly available genome-wide association studies, we employed single nucleotide polymorphisms (SNPs) strongly associated with educational attainment as instrumental variables. Two-sample Mendelian randomization analysis was used to investigate the causal relationship between educational attainment and SLE. The primary analysis method used was the inverse variance weighted with multiplicative random effects. Validation methods included inverse variance weighted with fixed effects and MR-Egger methods. Additionally, sensitivity analysis was conducted using the leave-one-out approach. Results Finally, 433 SNPs were included. The inverse variance weighted with multiplicative random effects analysis indicated no causal effect of educational attainment on the risk of SLE [odds ratio =1.111, 95% confidence interval (0.813, 1.518), P=0.509]. Similarly, the other two methods did not find any evidence of a causal relationship (P>0.05); however, significant heterogeneity was observed. The MR-Egger regression analysis provided no evidence of horizontal pleiotropy among the included instrumental variables (P>0.05). The leave-one-out approach did not identify any individual SNP that had a significant impact on the overall effect estimate. ConclusionIn conclusion, this study does not support a causal effect of educational attainment on the risk of SLE.
目的:研究领悟社会支持对护士生命质量的影响,进一步探讨领悟社会支持的作用,为提高护士身心健康水平提供依据和支持。方法:用WHOQOL-100量表中文版和领悟社会支持量表对我市三所二级甲等医院的499名护士进行问卷调查。结果:①护士生命质量总分较差。②护士领悟社会支持总分处于中等水平。③护士生命质量的各领域与社会支持均呈显著正相关。即社会支持越好,生命质量越高。结论:社会支持与个体心理健康有密切的关系。护士应主动寻求有效的、可利用的社会支持。护理管理人员则应培养护士良好的生理、心理状态和社会适应能力,从而使其生命质量得到提高。
Objective To compare the social support condition of Three Gorges migrants, that is, latter resettled migrants (in Chongqing) versus outside moving migrants (in Shandong). Methods Migrants were selected in both Chongqing Municipality and Shandong Province by a cluster random sampling method, and the survey was performed by completing the questionnaire of general status and the social support rating scale (SSRS). Results A total of 319 among 330 questionnaires distributed to Chongqing migrants were effective, accounting for 98.3%, and 320 among 340 questionnaires distributed to Shangdong migrants were effective, accounting for 94.1%. The results of the survey on social support showed that, a) The total score of social support of Chongqing migrants was significantly lower than that of Shandong migrants (Plt;0.01); b) The total score of Chongqing migrants in different genders was significantly lower than that of Shandong migrants in the same gender, respectively (Plt;0.05); c) All the scores of Chongqing migrants were significantly lower than those of Shandong migrants at the same age level except the objective score of the migrants at the age below 50 (Plt;0.05); and d) All the scores of Chongqing migrants were significantly lower than those of Shandong migrants at the same education levels except the objective score of the migrants at the education level above junior high school (Plt;0.05). Conclusion Compared to the latter resettled migrants in Chongqing, outside moving migrants in Shandong obtain more social support and fully take advantage of that.
