The paper elaborates on the present status of the study on mining beneath surface buildings from several aspects involving the techniques for reducing ground subsidence and deformation and the measures for protecting buildings. Following that, it is pointed out that, in the future, more efforts should be directed forwards the following aspects: the laws governing the ground movement; the techniques for constructing anti-deformation buildings; coal-bed gasification and protection of buildings; grouting of the overlying strata with bed separation phenomena; and the method for evaluating the stability of the ground above a worked-out area.展开更多
目的:探讨瘢痕疙瘩下埋植扩张器治疗大面积瘢痕疙瘩的临床疗效。方法:2006年8月—2017年8月,60例瘢痕疙瘩患者共65个部位的瘢痕疙瘩接受瘢痕疙瘩下埋植扩张器治疗。扩张器容量70～600 m L。经50～126 d注水扩张,行瘢痕疙瘩切除或部分切...目的:探讨瘢痕疙瘩下埋植扩张器治疗大面积瘢痕疙瘩的临床疗效。方法:2006年8月—2017年8月,60例瘢痕疙瘩患者共65个部位的瘢痕疙瘩接受瘢痕疙瘩下埋植扩张器治疗。扩张器容量70～600 m L。经50～126 d注水扩张,行瘢痕疙瘩切除或部分切除、扩张器取出和扩张皮瓣转移术,术中即时给予残留瘢痕疙瘩皮损内注射复方倍他米松注射液以及术后浅层电子束照射联合治疗。术后随访12～50个月不等。采用患者与观察者瘢痕评估量表评价疗效。结果:61个部位顺利完成整个治疗过程,4个胸部扩张器因外露提前取出。随访12个月以上,治愈47个部位(占77%);部分复发14个部位(占23%);完全复发0个部位。术前和术后12月的总POSAS评分分别为(59.31±4.94)分和(18.15±1.51)分(P<0.05)。结论:瘢痕疙瘩下埋植扩张器是治疗大面积瘢痕疙瘩较为理想的选择方法之一。展开更多
