BACKgROUND Entrapment of the temporal horn (ETH) is a rare pathologic condition. It is a kind of focal hydrocephalus caused by obstruction of flow pathway of cerebrospinal fluid. It is caused by various conditions, but ETH secondary to postoperative gamma-knife radiosurgery (gKS) is extremely rare. CASE SUMMARY A 52-year old previously healthy woman underwe.t resection of a large intraventricular meningioma. A small fragment of residual tumor with no obvious enlargement of the temporal horn was observed 3 mo after surgery, and she was referred for gKS. Two months after gKS, she complained of headache and progressive paralysis of the left limb. Magnetic resonance imaging revealed enlargement of the temporal horn. There was a second procedure to resect the residual tumor 8 mo after gKS. After the second procedure, she recovered smoothly. As of the date of this writing, she has remained in good condition. CONCLUSION This case reminds us that ETH should be considered in the treatment of intraventricular meningiomas, especially before gKS.

盗伐、滥伐林木材积数量是对案件定性、对行为人处罚的重要依据。目前材积测算的方法较多,相关法律法规对测算方法没有统一规定,导致同一案件出现多个测算结果。笔者采用案例研究、调查访问、模拟现场调查等方法,根据涉案林木的状态,分别对几种常用的测算方法的精度进行了比较研究,提出应根据不同案情确定材积测算方法;同一案情有多种测算方法时,应优先选用精度较高的方法,使测算结果具有唯一性,并经司法机关认可取得合法性。这样对盗伐、滥伐林木案件进行定案时可减少争议的出现,缩短办案时间,提高办理毁林案件的质量。

基于位移监测、数值计算、室内和现场试验等成果,从动力学角度开展了李家峡坝前水库滑坡稳定性预测的系统研究,获得了其滑带土的蠕变特性及水库滑坡的蠕滑机制,提出滑面剪应力比和滑带土黏滞系数的增减是决定滑坡能否从蠕滑转入剧滑的内在条件;通过模拟水库运行环境,完成了代表性滑块的现场促滑试验,研究表明:该类试验既是论证滑坡蠕滑机制的可靠方法,也是水库滑坡增稳治理的有效手段之一。
