浅谈胡澍手校本《素问》的文献版本价值

清末经学家和小学家胡澍把《素问》作为子书之一，博采众本，悉心校勘，以小学的方法进行专门研究，撰成《素问校义》，为研习《内经》不可不读之书。通过对天津中医药大学图书馆所藏胡澍手校本《重广补注黄帝内经素问》的考证，发现胡澍校勘所据底本一直被误作宋本，而实是明顾从德影宋刻本．校勘工作历时数年，手校本《素问》留有胡澍悉心对校后所做出的千余条校语，可惜草创未就，他便英年早逝。手校本这第一手资料，对研究胡澍的治学思想和《素问校义》的成书过程，学习和掌握知识，传承弘扬学术，都具有重女的文献参考价值。     

Neuroprotective effect of estrogen after chronic spinal cord injury in ovariectomized rats

BACKGROUND: At present, there is still lack of effective drugs for chronic spinal cord injury, whereas it is found recently that estrogen has a neuroprotective effect on brain and spinal cord injuries. OBJECTIVE: To observe the effect of estrogen on the apoptosis of nerve cells after gradual chronic spinal cord injury in ovariectomized rats. DESIGN: A randomized controlled animal trial. SETTING: Institute of Orthopaedics, the Second Hospital of Lanzhou University. MATERIALS: Sixty-five female Wistar rats of common degree, weighing 220–250 g, were provided by the experimental animal center of Lanzhou University. The rats were randomly divided into sham-operated group (n =5), estrogen-treated group (n =30) and saline control group (n =30), and the latter two groups were observed at 1, 3, 7, 14, 28 and 60 days respectively, and 5 rats for each time point. METHODS: All the rats were treated with bilateral oophorectomy 2 weeks before the experiment. T10 vertebral lamina was revolved into using plastic screw. The spinal canal impingement was not induced initially. After that, the original incision was opened to expose the screw every 7–10 days. MAIN OUTCOME MEASURES: The apoptosis and Caspase-3 positive cells in the damaged spinal cord were detected using terminal deoxynucleotidal transferase-mediated dUTP-biotin nick end labeling (TUNEL) method and Caspase-3 immunohistochemical staining at 1, 3, 7, 14, 28 and 60 days after chronic spinal cord injury respectively. RESULTS: Totally 65 rats were used, and the deleted ones during the experiment were supplemented by others. Changes of Caspase-3 expression after spinal cord injury: In the sham-operated group, only a small amount of Caspase-3 proteins were observed in the rat spinal cord, mainly located in motor neurons of spinal cord anterior horn. In the estrogen-treated group and saline control group, positive cells expressed occasionally at 1 day postoperatively, began to increase obviously at 7 days after injury, strongly expressed at 14 and 28 days, but decreased at 60 days, mainly located in the neurons of spinal cord gray matter anterior horn, and they expressed fewer in the motor neurons and white matter of ventral horn, and there were obvious differences between the estrogen-treated group and saline control group at 7, 14, 28 and 60 days (P < 0.05). CONCLUSION: Estrogen can reduce the apoptosis of nerve cells and promote the recovery of neurological function following gradual chronic spinal cord injury.

脊髓血管畸形合并胸腔血管畸形

脊髓血管畸形的临床发病率较低,仅为颅内血管畸形或脊髓新生物的1/10左右.本病可能与其它组织的血管异常同时存在,如皮肤血管痣(Cobb综合征),皮肤、粘膜病变,和Klipple-Trenaunay-Weber综合征等.本文报告的与胸腔血管畸形同时存在的脊髓血管畸形,我们尚未见诸报道.本文还结合文献就脊髓血管畸形导致脊髓功能损害的病理生理作了阐述.     

大白鼠肾上腺的血管构筑

本实验采用血管铸型扫描电镜,注射明胶卡红组织切片显微镜下观察和注射铅丹乳胶追踪血管来源三种方法对14只健康大白鼠肾上腺血管构筑进行了研究。大白鼠肾上腺动脉发自腹主动脉和肾动脉。它们在行程中发出分支至腺体表面,再次分支穿入囊内,逐级分支至毛细血管。皮质动脉发自囊内血管,它们在皮质中分支分布。球状带的毛细血管与囊的毛细血管相连,毛细血管在球状带围绕细胞团形成网眼状;在束状带呈放射状排列;在网状带吻合增多形成网状。髓质动脉亦发自囊的血管,它们在皮质中不发分支直抵髓质,在髓质分成毛细血管。网状带的毛细血管越向髓质口径越粗,它们在皮髓交界处互相吻合形成更粗的静脉,这些静脉逐级吻合,最后形成一主干——中央静脉,它穿出皮质出现于肾上腺门处。左侧的中央静脉注入在肾静脉,右侧的注入下腔静脉。     

Acute psychotropic effects of bilateral subthalamic nucleus stimulation and levodopa in Parkinson's disease.

High-frequency deep brain stimulation (DBS) of the subthalamic nucleus (STN) improves the motor symptoms of Parkinson's disease (PD). Opposite changes in mood, such as mania or depression, have been reported after surgery, but it is not known whether these side effects are specifically related to STN DBS. To learn whether STN DBS also influences the limbic loop, we investigated acute subjective psychotropic effects related to levodopa or bilateral STN DBS. After a median postoperative follow-up of 12 months, 50 PD patients completed the Addiction Research Center Inventory (ARCI), assessing subjective psychotropic effects in four conditions: off-drug/on-stimulation; off-drug/off-stimulation; on-drug/off-stimulation; and on-drug/on-stimulation. Both levodopa and STN DBS improved all the ARCI subscales, indicating subjective feelings of well being, euphoria, increase in motivation, and decrease in fatigue, anxiety, and tension. A suprathreshold dose of levodopa was significantly more effective than STN DBS, using the same electrical parameters as for chronic stimulation, on four of the five ARCI subscales. We concluded that 1) both STN DBS and levodopa have synergistic acute beneficial psychotropic effects in PD, 2) the psychotropic effects of both treatments need to be considered in the long-term management of chronic STN DBS, and 3) the results indicate an involvement of the limbic STN in mood disorders of PD.     

原发性十二指肠恶性肿瘤的影像学诊断

目的 探讨X线、CT及血管造影对原发性十二指肠恶性肿瘤的诊断价值及鉴别诊断。资料与方法 回顾分析经手术和／或病理证实的46例原发性十二指肠恶性肿瘤的l临床及影像学资料，46例全部作过十二指肠气钡双对比造影，并有13例作低张十二指肠插管造影；28例作CT检查；11例作数字减影血管造影。结果 胃十二指肠双对比造影及低张十二指肠插管诊断十二指肠癌24例；平滑肌肉瘤6例；恶性淋巴瘤4例。诊断总符合率为73．91％(34／46)。误诊率为17．39％(8／46)，漏诊率为8．7％(4／46)。CT检查28例，确诊十二指肠癌4例，平滑肌肉瘤7例。误诊为腹腔脓肿2例，平滑肌瘤6例，腹腔恶性肿瘤9例。诊断符合率为39．29％(11／28)，误诊率为60．71％(17／28)。血管造影11例，9例检出病变，6例确诊为十二指肠恶性肿瘤，3例误为良性肿瘤，2例未发现明显肿瘤血管。确诊率为54．55％(6／11)，误、漏诊率分别为27．27％(3／11)、18．18％(2／11)。结论 胃十二指肠气钡双对比造影是发现十二指肠恶性肿瘤最简单易行的方法，它和胃镜配合能得到病理学诊断。低张十二指肠插管造影对重度肠腔狭窄或阻塞患者显示病变范围起补充作用。CT能显示管外型恶性肿瘤的软组织块影及管壁破坏和有无淋巴结肿大。血管造影能根据血供来源明确钡餐难发现、CT仅显示与肠管无明显联系的平滑肌肉瘤，并可进行栓塞IE血治疗。

Adrafinil-induced orofacial dyskinesia.

We describe the first case of orofacial abnormal movements induced by adrafinil, a vigilance promoting agent of the same pharmacological class as modafinil. The dyskinesias did not spontaneously recover despite adrafinil withdrawal for a 4-month period. They were secondly dramatically improved by tetrabenazine, a presynaptic dopaminergic depleting drug which was introduced after the 4-month adrafinil-free period.
