Careful analysis on NBE can facilitate nowcasting of severe weather events and further understanding of their evolution. After detailed study on three cases concerning with NBE, it is concluded:(1) NBE triggered by fast moving echo in upstream is an important indication of disastrous wind;(2) NBE can develop into severe storm under proper conditions. There are often two stages during this kind of growing: the first is developing of initial echo, the second is snap growing of echo core;(3) Doppler radar reflects outflow of downburst as a nearly ringed NBE. Inside look on downburst can be obtained combining NBE with other data.

文章结合发生在上海的3次强对流天气个例，详细分析了弱窄带回波在分析和预报强对流天气中的作用，得出以下结论：（1）上游移动强回波的出流边界导致的弱窄带回波是大风预警的重要判断参考；（2）在合适的层结状态和抬升条件下，弱窄带回波会强烈发展，并导致局地雷雨大风，这类强对流天气的发展有两个比较重要的阶段：弱窄带回波上初始回波的发展和回波跃增；（3）下击暴流造成的地面出流在雷达回波上表现为近似圆弧的弱窄带回波，这种弱窄带回波与其他雷达观测特征以及地面观测相结合，有助于对产生下击暴流的对流云的发生发展过程进行细致分析。

Results By incubating cardiomyocytes with bFGF, ERKs was activated and the cellular viability 〔(70.0±4.6)%in bFGF 10 ng group vs.(53.0±4.5)%in H/R group, P＜0.01） and the ATP content 〔(23.1±2.3) nmol/106 cells in bFGF 10 ng group vs.(12.3±2.1) nmol/106 cells in H/R group, P＜0.01〕 were increased, also the LDH leakage 〔(257.3±51.0) U/L in bFGF 10 ng group vs.(372.5±69.2) U/L in H/R group, P＜0.05〕, was decreased, then attenuation of H/R injury to cardiomyocytes was observed. PD098059, an inhibitor of upstream kinase of ERKs completely abolished the protective effects 〔viability (57.0±5.8)%,ATP content (15.1±2.6) nmol/106 cells,LDH activity in medium (325.5±59.0)U/L in PD098059 group vs. bFGF 10 ng group, P＜0.01, respectively〕.

Two known genes lie within the implicated genetic interval. One is FTO (a locus associated with fat mass and obesity), which has been implicated in nucleic acid demethylation and is highly expressed in the arcuate nucleus of the hypothalamus; the other, called fantom, or FTM (KIAA1005 or RPGRIP1L), begins transcription at a location only 200 base pairs upstream from the 5' end of FTO. FTM is a structural component of the ciliary body, present on all cells, that plays a role in a wide range of cellular and organ functions.9 Elements of the cilium are mutant in Bardet Biedl syndrome, which includes obesity among its characteristic phenotypes.10
