The generic distributions in both modern and fossil times were outlined, and their distribution center, place and time of origin and the way of dispersal were discussed. An attempt was made to discuss early differentiation, geographical radiation and morphological evolution of the family on the background of paleogeography and paleoclimatology, tracing back as far as the Late Cretaceous and Early Tertiary.

Results As the results, there was 6 patients with the ILVT cycle length of (286±38)ms. The indicaed site of EA by noncontact mapping was at the middle septum in 4 patients, and at the inferior septum in 2 patients. Mean time of EA was (48.6±32.8)ms before onset of the surface QRS. The length of conduction pathway was (2.6±0.9)cm. The ablation catheter mapping showed perfect match in at least 11 of 12 leads at the EX (≥11/12), but not at the EA (≤10/12) with pace mapping during sinus rhythm. Purkinje potentials were mapped at EA and CP in all cases, but only one case at EX, and diastolic potentials were mapped at EA in 2 cases during ILVT. All cases were successfully ablated by area ablation at EA or/and line ablation at CP during sinus rhythm. None suffered a recurrence during (12±6) months follow-up.
6例ILVT周长为(286±38)ms,非接触标测显示4例激动起源位于中间隔,2例位于下间隔,EA较体表QRS波提前约(48.6±32.8)ms,传导径路长约(2.6±0.9)ms.6例病人在窦性心律下消融导管起搏标测12导联QRS形态与ILVT相匹配(≥11/12)处位于EX,而非EA(≤10/12)见正文。6例病人在室性心动过速期间消融导管于EA和CP处标测到PP,2例于EA标测到DP,1例于EX标测到PP.6例病人在窦性心律下于ILVT起源部位行片状或/和传导径路作线性消融均获成功,随访(12±6)月,未见复发。

Welfare is a kind of periphrastic juvenile control policy, the pretext to constructing juvenile justice system, and the groundwork that cannot been threw away during the development of juvenile justice.
本文通过对美国少年司法起源与变迁史的考察发现,无论是多么伪善或者直白,少年司法起源与变迁背后的推动力均主要源自成人社会控制少年的需要;而少年司法政策的演变规律则呈现出在福利与惩罚之间调整其立场,在总体上走向折中主义的趋势;作为一种"隐蔽而迂回"的少年控制策略,福利是建构少年司法的旗帜,也是少年司法变迁中难以背弃的根基。19世纪以前的美国,大体处于"前少年司法时代"。
