苦参地肤洗剂治疗急性湿疹42例临床观察

目的：探讨苦参地肤洗剂治疗急性湿疹的临床疗效。方法：将急性湿疹患者84 例随机分为治疗组和对照组,每组各42 例。治疗组采用苦参地肤洗剂冷湿敷治疗,对照组采用3%硼酸洗液冷湿敷治疗,疗程均为2周。观察2组湿疹面积及严重程度指数（EASI）评分、瘙痒程度［视觉模拟评分法（VAS）评分］及生活质量指数（DLQI）评分,并评定综合疗效。结果：总有效率治疗组为92.86%（39/42）,高于对照组的76.19%（32/42）,差异有统计学意义（P<0.05）。治疗后EASI评分及治疗前后EASI评分差值2组间比较,差异均无统计学意义（P＞0.05）;治疗后VAS评分、DLQI评分及其治疗前后差值2组间比较,差异均有统计学意义（P<0.05或P<0.01）。结论：苦参地肤洗剂治疗急性湿疹效果明显,使用方便,疗效较3%硼酸洗液优,值得临床推广。

东亚夏季大气环流和气候对冬季海温异常的邻响应和遥响应

本文通过ＩＡＰ－ＧＣＭ的数值模拟,研究了全球大气环流对黑潮海域和赤道东太平洋冬季ＳＳＴ异常的响应,并着重比较东亚大气环流和气候对黑潮区ＳＳＴＡ的响应（邻响应）和对赤道东太平洋ＳＳＴＡ的响应（遥响应）。首先,无论是黑潮区ＳＳＴＡ引起的邻响应还是赤道东太平洋ＳＳＴＡ所引起的遥响应对东亚大气环流和气候变化的影响都是明显而重要的。由于在大气中低频振荡被激发出来,其响应将持续较长时间。进一步分析表明,东亚大气环流对黑潮区或赤道东太平洋冬季正ＳＳＴＡ的响应都将造成华北地区夏季的多雨,其数值模拟结果与观测相一致。另外,赤道西太平洋地区大气的异常（尤其是对流活动）对于东亚地区大气环流和气候变化有重要作用

Movement patterns of an endangered fishery species,Lithognathus lithognathus (Sparidae), and the role of no-take marine protected areas as a management tool

Understanding movement behaviour is essential for effective management of fishery species. Dart tags were used to study coastal movement patterns of white steenbras Lithognathus lithognathus, an overexploited seabream (Sparidae) in South Africa. In total, 6 962 fish (190–1 080 mm fork length) were tagged throughout the species’ distributional range, in four long-term fish-tagging programmes. The predominant behaviour recorded was residency, with relatively short-ranging movements. More than 60% of the 351 recaptured fish were recaptured within 1 km of their tagging site, some of which were at liberty in excess of three years. Most of the juveniles (93.9%), subadults (71.7%) and adults (64.0%) were recaptured within 10 km. Occasional long-distance movements of up to 800 km were recorded. Recapture distances were positively, but weakly, correlated with fish fork length (n = 257 fish measured at recapture; r² = 0.166, p < 0.001). Low levels of connectivity among coastal areas suggest that large-scale annual spawning migrations, as previously hypothesised for this species, are unlikely, which raises the possibility of multiple spawning sites. Seventy-seven percent of L. lithognathus tagged within three marine protected areas (MPAs) were recaptured within the same MPA, suggesting that area closures provide protection for L. lithognathus through the post-estuarine juvenile, subadult and adult life stages. We confirm that the country’s current network of coastal MPAs plays a vital role in sustaining this species, and suggest that additional closures, or otherwise substantial reductions in catch rates, are necessary for the species’ recovery.     

兰新第二双线铁路防风明洞实验段风荷载数值模拟研究

介绍了高速铁路防风明洞的基本作用及设计方法;利用计算流体动力学原理中的数学模型及控制方程,对兰新第二双线铁路防风明洞大风作用下的风荷载进行了分析;通过计算工况的假定以及边界条件的合理设定,采用有限体积法建立防风明洞数值分析模型,并模拟计算了平地路段、浅路堑地段和路堤地段三大类工况和70、60、50、40m/s4种风速情况。研究结果表明：①开孔情况下,明洞各部位所受风荷载随着风速增大而增大;②明洞迎风侧均为正压,平地地段与路堤地段所受正压较接近,最大值出现在风速为70m/s时,迎风边墙正压为3202Pa;③明洞拱顶及背风侧均为负压,浅路堑地段所受负压最大值出现在风速为70m/s时,拱顶负压为-3550Pa;④各地段背风侧所受负压均小于-1500Pa,背风墙脚与背风边墙受力基本相同;⑤各地段各风速情况下,拱顶处负压均为最大;⑥开孔情况下的明洞各部位风荷载,普遍小于不开孔情况;⑦明洞开孔附近有回流风速,并随着外界风速增大而增大。

Juvenile slender tuna from New Zealand (note)

Two juvenile slender tuna Allothunnus fallai Serventy, 278 mm and 282 mm fork length, were identified from a catch by a purse seiner 23 km off the Moko Hinau Islands, New Zealand, on 23 January 1974. As the slender tuna were observed to school in association with skipjack tuna Katsuwonus pelamis L., it is probable that adults also school, and could be available as a yet unexploited resource to New Zealand fishermen, especially to the south‐east of New Zealand.     

Tagging experiments on blue cod (Parapercis colias) in the Marlborough Sounds,New Zealand

From 1973 to 1976, 2430 blue cod (Parapercis colias) were tagged in the Marlborough Sounds. Tags from 84 fish (3.5%) were returned, after a mean 138 days at liberty. Of these, 71.6% had not moved significant distances. The remainder had travelled up to 41.7 km. Tag shedding rates, as indicated by multiple‐tagging experiments, were high. Results suggest that blue cod of the Marlborough Sounds and the adjacent islands belong to the same stock, and that, while some move significant distances, the majority stay in 1 place for extended periods.
