BACKGROUND Radiation therapy(RT)for nasopharyngeal cancer can cause several complications.In rare cases,an internal carotid artery pseudoaneurysm can occur,which can be fatal.We report the experience of a nasopharyngeal cancer patient who underwent radiation therapy and subsequently developed a fatal pseudoaneurysm of the petrous internal carotid artery.CASE SUMMARY A 39-year-old man was diagnosed with nasopharyngeal cancer 2 years ago(American Joint Committee on Cancer Stage T3N2M0)and received concurrent chemoradiation therapy.He subsequently relapsed and received chemotherapy.One week after the 4th cycle of chemotherapy,he was admitted to the emergency room of our hospital because of massive epistaxis accompanied by a headache.A pseudoaneurysm of the petrous internal carotid artery was confirmed by digital subtraction angiography(DSA).Stent-assisted endovascular coil embolization was performed and complete occlusion was achieved.No pseudoaneurysm was observed on DSA after coil embolization;however,intermittent epistaxis was maintained even after coil embolization.After seven days,a diagnostic laryngoscopy was performed.Massive bleeding occurred after aspiration of the blood clot during the laryngoscopy and the patient died of hypovolemic shock.In this case,epistaxis may have been a sign of pseudoaneurysm;therefore,treatment such as embolization should be performed promptly,and careful management should be undertaken after treatment.CONCLUSION This case highlights a rare,serious complication of RT in nasopharyngeal cancer and how it should be recognized and treated.

Coordinated movement is generated by communication between the cerebrum and cerebellum via the cerebellar peduncles (CPs). The CPs are classified into three types (superior, middle, and inferior), and each includes a variety of neural tracts. Among those tracts, the cortico-ponto-cerebellar tract (CPCT), a middle CP, is involved in motor planning and initiation of movement, while the dentato-rubro-thalamic tract (DRTT), a superior CP, is involved in motor coordination, movement timing, verbal fluency, and working memory (Kase et al., 1993.

Neural Regeneration Research 2016年第1期11卷 130-131页

作者： Sung Ho jang Hyeok gyu Kwon Department of Physical Medicine and Rehabilitation College of Medicine Yeungnam University

Traumatic brain injury（TBI）is a common disability-causing neurological disorder.For successful rehabilitation of TBI patients,a thorough evaluation of the presence and extent of neural injury is essential for determining the optimal rehabilitation strategy and accurate prognosis.However,it is difficult to determine the status of neural tracts.

Recovery of an injured anterior cingulum to the basal forebrain in a patient with brain injury: a 4-year follow-up study of cognitive function

引用

Neural Regeneration Research 2016年第10期11卷 1695-1696页

作者： Sung Ho jang Hyeok gyu Kwon Department of Physical Medicine and Rehabilitation College of Medicine Yeungnam University

The cingulum, a long neural tract extending from the orbitof- rontal cortex to the medial temporal lobe, obtains cholinergic innervation from three cholinergic nuclei in the basal fore- brain （the nucleus basalis of Meynert [Ch 4], the medial septal nucleus [Ch 1 ], and the vertical nucleus of the diagonal band [Ch 2]）, and is the passage of the medial cholinergic pathway which supplies cholinergic innervation from the basal forebrain to the cerebral cortex （Folstein et al., 1975; Selden et al., 1998; Lucas-Meunier et al., 2003）. Therefore, it is important for cog- nition, especially memory function （Selden et al., 1998）.

Motor weakness is a common and important sequela of stroke,and motor recovery is mostly achieved within 3 months following stroke（Jorgensen et al.,1995;Fujii and Nakada,2003）,suggesting the importance of active rehabilitation during the early stage of stroke.Many studies have reported on neurological recovery during this period,however,little is known about pontine infarction（jang et al.,2007;Kwon and jang,2012;Kwon

表面应力耦合异质结构是一种改善非均相催化剂催化性能的有效策略.它可以在调控催化剂电子结构的同时,促进电荷传输.一般来说,Bi基催化剂对CO_(2)电还原为甲酸的选择性高于ZnO,但是金属Bi的价格高于Zn.本文以十六烷基三甲基溴化铵为模板剂,通过一步水热法合成了一种具有多孔纳米片形貌的Bi_(2)O_(2)CO_(3)/ZnO异质结催化剂,用于高效电催化CO_(2)还原制备甲酸.在-1.0 V vs.RHE下,该催化剂展现出最大甲酸盐法拉第效率(92%),且在施加-1.2 V vs.RHE电压下甲酸盐偏电流密度为200 m A mg_(Bi)^(-1).更重要的是,对Bi的质量进行归一化发现,Bi_(2)O_(2)CO_(3)/ZnO的质量活度比纯Bi_(2)O_(2)CO_(3)的质量活度提升了3.1倍.通过X-射线光电子能谱和X-射线吸收谱测试表明,在该催化剂中,界面Zn原子电荷向Bi原子转移,形成了富电子的Bi_(2)O_(2)CO_(3)表面,有利于CO_(2)的捕获和活化;而异质结构引起的压缩应力有利于优化反应中间体的吸附能,二者协同提高了Bi_(2)O_(2)CO_(3)/ZnO电催化CO_(2)还原生成甲酸的选择性和活性.

Perspectives on the neural connectivity of the fornix in the human brain

引用

Neural Regeneration Research 2014年第15期9卷 1434-1436页

作者： Sung Ho jang Hyeok gyu Kwon Department of Physical Medicine and Rehabilitation College of MedicineYeungnam UniversityTaeguRepublic of Korea

The fornix is involved in the transfer of information on episodic memory as a part of the Papez circuit. Diffusion tensor imaging enables to estimate the neural connectivity of the fornix. The anterior fornical body has high connectivity with the anterior commissure, and brain areas rele- vant to cholinergic nuclei （septal forebrain region and brainstem） and memory function （medial temporal lobe）. In the normal subjects, by contrast, the posterior fornical body has connectivity with the cerebral cortex and brainstem through the splenium of the corpus callosum. We believe that knowledge of the neural connectivity of the fornix would be helpful in investigation of the neural network associated with memory and recovery mechanisms following injury of the fornix.

Delayed degeneration of an injured spinothalamic tract in a patient with diffuse axonal injury

引用

Neural Regeneration Research 2017年第11期12卷 1927-1928页

作者： Sung Ho jang Hyeok gyu Kwon Department of Physical Medicine and Rehabilitation College of MedicineYeungnam UniversityDaemyungdongNamkuDaeguRepublic of Korea Department of Physical Therapy College of Health SciencesCatholic University of PusanPusanRepublic of Korea

Diffuse axonal injury （DAI） is one of the devastating mechanisms of traumatic brain injury （TBI） and shows extensive sub- cortical lesions due to shearing forces induced by rapid acceleration-deceleration and rotation of the brain （Adams et al., 1982; Meythaler et al., 2001）. As a result, conventional brain imaging techniques including brain MRI have been limited in demon- strating neuronal degeneration in patients with DAI. However, diffusion tensor tractography （DTT）, which is derived from diffusion tensor imaging （DTI） has enabled three-dimensional reconstruction of the neural tracts （jang and Seo, 2014）. Since the introduction of DTI, several studies have demonstrated neuronal degeneration after TBI （Tomaiuolo et al., 2005; Hong and lang, 2010; Kwon and jang, 2014）. However, little is known about delayed neuronal degeneration in patients with TBI.
