盐度对变化2014年东北太平洋“暖泡”的作用

A significant strong, warm "Blob"(a large circular water body with a positive ocean temperature anomaly)appeared in the Northeast Pacific(NEP) in the boreal winter of 2013–2014, which induced many extreme climate events in the US and Canada. In this study, analyses of the temperature and salinity anomaly variations from the Array for Real-time Geostrophic Oceanography(Argo) data provided insights into the formation of the warm"Blob" over the NEP. The early negative salinity anomaly dominantly contributed to the shallower mixed layer depth(MLD) in the NEP during the period of 2012–2013. Then, the shallower mixed layer trapped more heat in the upper water column and resulted in a warmer sea surface temperature(SST), which enhanced the warm"Blob". The salinity variability contributed to approximately 60% of the shallowing MLD related to the warm"Blob". The salinity anomaly in the warm "Blob" region resulted from a combination of both local and nonlocal effects. The freshened water at the surface played a local role in the MLD anomaly. Interestingly, the MLD anomaly was more dependent on the local subsurface salinity anomaly in the 100–150 m depth range in the NEP.The salinity anomaly in the 50–100 m depth range may be linked to the anomaly in the 100–150 m depth range by vertical advection or mixing. The salinity anomaly in the 100–150 m depth range resulted from the eastward transportation of a subducted water mass that was freshened west of the dateline, which played a nonlocal role.The results suggest that the early salinity anomaly in the NEP related to the warm "Blob" may be a precursor signal of interannual and interdecadal variabilities.     

三联针法结合下关穴深位注射治疗过敏性鼻炎72 例

目的：观察三联针法结合下关穴深位注射治疗过敏性鼻炎的临床疗效。方法：将过敏性鼻炎患者150 例随机分为治疗组和对照组,每组各75 例。治疗组采用三联针法结合下关穴深位注射治疗,对照组采用常规针刺法治疗。2组均治疗20 d,治疗结束后随访3个月。比较2组治疗前后的综合疗效,临床症状（喷嚏、鼻塞、流涕、鼻痒）及生活质量的改善情况。结果：治疗组脱落3例,对照组脱落4例。总有效率治疗组为93.06%（67/72）,对照组为76.06%（54/71）,2组比较,差异有统计学意义（P<0.01）;治疗后2组临床症状评分及鼻结膜炎生存质量量表（ＲQLQ)各维度评分均较治疗前下降,且治疗组各项评分均低于对照组,差异均有统计学意义（P<0.05或P<0.01）。结论：三联针法结合下关穴深位注射治疗过敏性鼻炎可明显缓解临床症状,提高生活质量,值得临床推广应用。
