目的探讨两种不同多个混合纯音频率声在慢性主观性耳鸣患者中的治疗效果。方法选择2021年4月~2023年4月慢性主观性耳鸣患者100例为对象,用随机数字表法分为两组各50例。两组均采用常规方法治疗,在此基础上,对照组声治疗以耳鸣检测中测得的耳鸣频率为中心频率,由7倍频程的不同频率纯音构成,观察组以耳鸣检测中测得的耳鸣频率为中心频率,由9个1/3频程的不同频率纯音构成,两组均完成3个月治疗,比较两组有效率、耳鸣残障量表(THI)、耳鸣严重程度评估量表(TEQ)、血清细胞黏附因子-1(sVCAM-1)及一氧化氮(NO)水平。结果治疗3个月后,观察组有效率为96.00%,高于对照组84.00%(P<0.05);治疗3个月后,观察组功能性、情感性、灾难性及TEQ评分,sVCAM-1及NO水平低于对照组(P<0.05)。结论由9个1/3频程的不同频率纯音构成的混合音频率声治疗慢性主观性耳鸣有效率较高,能改善患者耳鸣症状,有助于降低sVCAM-1及NO水平。

Objective Poisonous plants are a deadly threat to public health in China. The traditional clinical diagnosis of the toxic plants is inefficient, fallible, and dependent upon experts. In this study, we tested the performance of DNA barcodes for identification of the most threatening poisonous plants in China. Methods Seventy-four accessions of 27 toxic plant species in 22 genera and 17 families were sampled and three DNA barcodes （motK, rbcL, and ITS） were amplified, sequenced and tested. Three methods, Blast, pairwise global alignment （PWG） distance, and Tree-Building were tested for discrimination power. Results The primer universality of all the three markers was high. Except in the case of ITS for Hemerocollis minor, the three barcodes were successfully generated from all the selected species. Among the three methods applied, Blast showed the lowest discrimination rate, whereas PWG Distance and Tree-Building methods were equally effective. The ITS barcode showed highest discrimination rates using the PWG Distance and Tree-Building methods. When the barcodes were combined, discrimination rates were increased for the Blast method.

The rapid growth of grain yield in China accelerates a discussion on whether the grain system in China is sustainable. To answer the question, a comprehensive assessment from economic and environmental points is necessary. This study jointly used economic analysis(ECA), emergy evaluation(EME) and carbon footprint(CF) to analyze the environmental and economic sustainability of the grain production system in China based on the national statistical data during 2000–2015. Results showed that the costs of maize, wheat, rice and soybean had increased by 252-346% from 2000 to 2015, causing the lower profit of grain system in recent years. The situation resulted in a serious problem on economic sustainability of grain system in China. Meanwhile, the emergy sustainability index(ESI) of maize, wheat, rice and soybean systems were increasing during 2000–2015, and the CF on unit yield of the crops had been reduced by 10-30% in the study period. The results reflected the improved environmental sustainability of grain system in China during 2000–2015. Nevertheless, the emergy flow of industrial inputs for the crops were increased by 4-22% in the study period, and the CF from the inputs presented a growth rate of 16-23% as well during the same period. The results implied that the grain system in China was relying more on fossil-based inputs. Finally, according to the key points of cost, emergy and CF, we suggest that improving labor efficiency, advanced agricultural practices and optimizing cropping pattern will be effective ways to further improve the economic and environmental sustainability of grain system in China.
