Quiet rest ameliorates biochemical metabolism in the brain in a simple concussion rabbit model Evaluation of hydrogen proton magnetic resonance spectroscopy

The present study analyzed changes in the biochemical metabolites N-acetyl aspartate, choline, and creatine in a simple concussion rabbit model following quiet rest, hyperbaric oxygen therapy, or interference stimulation through the use of hydrogen proton magnetic resonance spectroscopy detection. Experimental findings showed that brain N-acetyl aspartate and choline peak values significantly decreased, while creatine peak values significantly increased following simple concussion. Following treatments, N-acetyl aspartate and choline peaks returned to normal levels in the quiet rest and hyperbaric oxygen therapy groups, but no changes were observed in the interference stimulation group. Results demonstrated abnormal changes in the brain biochemical metabolism environment following simple concussion. Quiet rest was shown to play an important role in restoration of biochemical metabolism following simple concussion.

嗓音训练促进声带息肉患者术后嗓音恢复的效果评价

目的:探讨嗓音训练在促进声带息肉患者术后嗓音恢复中的价值。方法:将2020年5月-2022年8月在宜春市第二人民医院择期行声带息肉切除术的50例患者为研究对象。使用电脑软件按照入院顺序进行随机分组(25例/组)。观察组有男性15例,女性10例,平均年龄(37.14±4.83)岁,平均发病时间为(3.04±0.83)年;对照组有男性14例,女性11例,平均年龄(37.35±4.75)岁,平均发病时间为(3.03±0.42)年。对照组要求患者在术后要禁声休息,观察组术后接受嗓音训练。比较两组患者术后效果以及训练前后嗓音障碍指数量表(VHI)评分、嗓音嘶哑程度量表(GRBAS)评分的变化情况。结果:观察组术后4周有效率为100.00%,对照组为96.00%,差异无统计学意义(P>0.05);观察组训练后功能评分、生理评分、情感评分及VHI总评分均低于对照组,训练后G评分、R评分、B评分及GRBAS总评分也均低于对照组,差异均有统计学意义(均P<0.05);观察组术后嗓音恢复总满意度高于对照组,差异有统计学意义(96.00%比76.00%,P<0.05)。结论:嗓音训练在促进声带息肉患者术后嗓音恢复中有良好作用,可提升患者的嗓音恢复满意度。

城市公园安静休息区选址的参数化设计方法研究

信息技术的高速发展推动了参数化设计的产生和飞速发展,运用参数化方法,通过数据分析和运算,辅助景观各要素的设计和优化问题,成为现代景观设计的重要发展趋势。在分析了区位、地形、水体等安静休息区影响要素的基础上,首先提出了安静休息区选址的参数化设计思路。随后,以天津市水西庄公园为例,以Rhino+Grasshopper为参数化设计平台,利用公园测绘图构建场地数据模型,设置位置、地形、水体等要素的设计规则,探讨了城市公园安静休息区选址的参数化设计方法,为公园基于数据模型进行选址的参数化设计提供借鉴。
