The results showed that during the monitoring period from March 24 to 27 in 2015, the primary source of fine particulate matter in Nao'ao County was motor vehicle exhaust, that is, 24.7% of fine particulates were from motor vehicle exhaust, followed by biomass burning (17.2%), fire coal (17.2%), and sea salt (13.3%). The proportions of fire coal and sea salt revealed the peculiarity of sources of atmospheric fine particulate matter in Nan'ao County. Therefore, it is suggested that some measures should be adopted to limit tourist traffic to reduce the adverse impact of motor vehicle exhaust on ambient air quality in Nan'ao County.展开更多

目的比较手术治疗与保守治疗B1型踝关节骨折的临床效果。方法选择2015年8月至2017年10月中国中医科学院广安门医院南区收治的67例AO 44-B1型踝关节骨折,其中32例接受手术治疗(手术组),35例接受保守治疗(非手术组)。分别于治疗后3、6、1...目的比较手术治疗与保守治疗B1型踝关节骨折的临床效果。方法选择2015年8月至2017年10月中国中医科学院广安门医院南区收治的67例AO 44-B1型踝关节骨折,其中32例接受手术治疗(手术组),35例接受保守治疗(非手术组)。分别于治疗后3、6、12个月使用美国骨科医师学会足踝功能调查问卷(foot and ankle orthopaedics questionnaire,FAOQ)评估踝关节功能,使用健康调查12条简表(12-item short-form from health survey,SF-12)中的躯体功能相关评分(short form-12-physical component score,SF-12-PCS)评估患者的生活质量,并记录两组患者的并发症发生情况及住院时间等。结果治疗后3、6、12个月两组的FAOQ评分及SF-12-PCS评分比较差异均无显著性(P>0.05),但手术组的住院时间(P=0.0017)和一般并发症发生率(P=0.02)高于非手术组。结论对于AO 44-B1型踝关节骨折,手术治疗的短期预后并不优于非手术治疗,且增加了住院时间及并发症发生率。展开更多
目的探讨β-环连蛋白抑制基因1(dapper antagonist of catenin-1,DACT1)对Ⅰ型上皮性卵巢癌迁移侵袭能力的影响及可能机制。方法免疫组织化学检测Ⅰ型人卵巢癌临床组织中DACT1的表达;采用人黏液性卵巢癌细胞株3AO构建外源性转染DACT1的...目的探讨β-环连蛋白抑制基因1(dapper antagonist of catenin-1,DACT1)对Ⅰ型上皮性卵巢癌迁移侵袭能力的影响及可能机制。方法免疫组织化学检测Ⅰ型人卵巢癌临床组织中DACT1的表达;采用人黏液性卵巢癌细胞株3AO构建外源性转染DACT1的稳转株,通过划痕实验、Transwell迁移及基质胶侵袭实验检测细胞运动能力;免疫荧光观察DACT1对细胞骨架重塑的影响。结果Ⅰ型卵巢癌组织中DACT1表达低于正常卵巢组织(P<0.01)。外源性转染DACT1后3AO细胞株迁移侵袭能力降低(P<0.01),且腹腔内成瘤能力有所下降,细胞骨架中特化膜结构减少。结论 DACT1对Ⅰ型卵巢癌浸润转移具有抑制效应,其在Ⅰ型卵巢癌组织中的低表达可能与其疾病发生相关。展开更多
