Abstract： Background Low back pain（LBP）in middle-aged and elderly adults has become a significant public health issue worldwide. Physical activity and sleep are two core components of the 24-hour lifecycle，and maintaining adequate physical activity and good sleep are crucial for health，both of which are associated with LBP. Objective To investigate the prevalence of LBP in middle-aged and elderly adults in China，analyze the independent and combined effects of physical activity and sleep on its occurrence，and provide scientific evidence for behavioral health. Methods Based on the 2018 China Health and Retirement Longitudinal Study，participants without demographic，physical activity，sleep，and LBP data were excluded. A total of 13 496 eligible individuals aged 45 to 69 were included，and their demographic and behavioral information was collected. Binary logistic regression and multiple linear regression were used to examine the relationship between physical activity，sleep duration，and LBP，and a mediation model was constructed to analyze the mediating effect of sleep duration on the association between physical activity and LBP. Results The prevalence of LBP among the 13，496 participants was 39.0%（n=5 269）.Inadequate sleep（<7 hours）was reported by 57.1%（n=7 704）of middle-aged and elderly adults in China，with 11.6%（n=1561）engaging in mild physical activity and 88.4%（n=11 935）engaging in moderate to high-intensity physical activity. The multicollinearity diagnosis results for confounding variables（e.g.，gender，age，alcohol consumption，and smoking） showed that all variance inflation factors were less than 5，indicating no collinearity. Regression analysis revealed a positive correlation between physical activity and LBP（β=0.120，P<0.05），a negative correlation between sleep duration and LBP（β=-0.220，P<0.01），and a negative correlation between physical activity and sleep duration（β=-0.081，P<0.05）. The mediation analysis of categorical variables indicated Z=2.223>1.96，and the path from physical activity to LBP was not significant（β=0.105，P>0.05），suggesting a complete mediating effect of sleep duration on the association between physical activity and LBP. Conclusion Over one-third of middle-aged and elderly adults in China suffer from LBP. Higher levels of physical activity or shorter sleep duration are associated with increased risk of LBP. Sleep duration plays a complete mediating role in the association between physical activity and LBP，where the increased risk of LBP associated with high-intensity physical activity is completely transmitted through reduced sleep duration. Adequate sleep duration plays an important role in reducing the risk of LBP associated with high-intensity physical activity. This study suggests that older adults should adjust their exercise intensity according to their own conditions and maintain adequate sleep duration to reduce the risk of LBP.

Abstract： Objective To construct continuous nursing quality evaluation indicators for inflammatory bowel disease patients, and to provide a basis for the evaluation of continuing care quality. Methods The first draft of evaluation indicator was constructed through literature review and qualitative interview, based on the three-dimensional quality management model of "structure-process-result". The first draft was revised through 2 rounds of Delphi technique, and the indicator weight was calculated by analytic hierarchy process. Results Total 15 experts completed 2 rounds of consultation. The questionnaire recovery rates were 100%; the expert authority coefficients were 0.930 and 0.919, respectively. Kendall harmony coefficients were 0.149 and 0.177 (P < 0.05). The average value of each indicator ranged from 4.33 to 5. The final nursing quality indicator system of continuing care of inflammatory bowel disease included 3 first-level indicators, 10 secondary-level indicators and 39 third-level indicators. Conclusion The evaluation indicators of continuous care for patients with inflammatory bowel disease constructed in this study are scientific, reliable and practical, and it can provide references for the evaluation of continuing care quality for patients with inflammatory bowel disease.

Abstract： The pollution from bulk coal combustion was thought to be one of the main causes of haze weather in northern China, so governments everywhere tried to promote the search for an alternative to civil bulk coal. Specially, so-called “clean energy” was vigorously promoted and coal-to-electricity or natural gas conversion project was implemented in the Beijing-Tianjin-Hebei metropolitan area, while burning high-quality anthracite and semicoke was encouraged in the surrounding areas, though giving rise to unsatisfactory influence finally. Several typical decentralized civil heating technologies in China were comparatively analyzed in this article. It is suggested that the coal-to-electricity or natural gas conversion project must be on the premise of rich resources, suitable geographic conditions, and high-level economic development as well as conforming to living habits of the local people, among which the economic affordability is one of the key factors to success. In order to solve the pollution problem of bulk coal combustion in remote low-income rural areas thoroughly, a long-term plan should be made to realize clean heating by burning bituminous briquette in environment-friendly domestic furnaces such as decoupling combustion stoves.

Abstract：为解决沙冬青（Ammopiptanthus mongolicus）主根长、毛细根少，育苗生根困难、移栽成活率低的林业技术难题，该研究对不同发育程度沙冬青幼苗进行不同强度断根与不同浓度激素处理（IBA）添加，促根培养后测定并分析不同组合处理对沙冬青幼苗根系形态、根系质量及幼苗生长的影响，以探究沙冬青促根成活关键措施，为沙冬青育苗及造林技术提供基础依据。结果表明：（1）断根可促进沙冬青多主根的发生，以及侧根、根总量、幼苗地上地下部分生物量、根冠比、根系活力和根系阳离子交换量（CEC）的增加。其中，幼苗根长达1.5~2.0 cm时断根尖0.5 cm（F2）处理显著促进侧根数、根尖数、分支数、苗木质量指数和根系活力的增加，且根系活力达到断根处理的峰值（较对照显著提高137.70%）；根系CEC在根长达4.5~6.0 cm时断根长1/2（T3）处理时最佳。（2）断根后激素的促根及幼苗生长作用进一步提高。其中，根长1.5~2.0 cm时断根尖0.5 cm+0.075 mgL-1 IBA/0.125 mgL-1 IBA（即P3、P4）处理后根系形态指标（除平均根长外）、根系CEC显著大幅增加；P4处理后幼苗鲜重、根干重、根冠比、苗木质量指数和根系活力最高。P3处理下根中可溶性糖、NSC含量较对照显著增加26.04%和29.07%，根可溶性蛋白含量在P4处理下达到峰值（13.27 mgg-1）。适当断根与IBA添加可通过改变根系形态和提高根系活力一定程度上促进沙冬青根系吸收和养分存储，进而提高根系质量和幼苗生长潜力。
