Pulse X-ray diagnostics is capable of reducing the radiation exposure considerably. As for pulse X-ray diagnostic machines, which form pulses with the duration of 0.1 μs, using them one can get outstanding results in this area. This fact can be explained by the long period of luminophor persistence in intensifying X-ray luminescent screens. In this paper we present experimental data, comparing radiation doses, measured at pulse X-ray apparatus and apparatus of constant radiation.

Objective: To determine the diagnostic value of motor ev.k.d potentials (MEPs ) in the diagnosis of lumbosacral cord disorders. Methods: MEPs in 37 patients with sensory and motor deficits in the lower limbs were studied. MRI demonstrated spinal cord involvement in 10 patients and cauda equina lesions in 27 patients. A double determination of cent ral motor conduction time (CMCT), calculated as the difference between the laten cies of responses ev.k.d by cortical and paravertebral magnetic stimulation and as the difference between the latency of cortical MEP and the total peripheral c onduction time calculated from the F-wave latency, enabled discrimination betw een a delay along the proximal root and a delay along the corticospinal tract. A n abnormality of the CMCT calculated with both techniques is indicative of centr al motor pathway damage, whereas an abnormality of the CMCT calculated from the latency of responses ev.k.d by paravertebral magnetic stimulation associated wit h a normal CMCT calculated from the F-wave latency suggests a cauda equina les ion. Results: neurophysiologic findings strongly correlated with the lesion site documented by MRI (cauda equina or lumbosacral cord). All patients with MR evid ence of cord involvement had an abnormality of CMCT calculated with both methods , suggesting a lesion of central motor pathways. Clinical examination often fail ed to document a spinal cord lesion, suggesting pure peripheral involvement in 5 of the 10 patients with MR evidence of cord lesion. Conclusion: Motor ev.k.d po tential recording is an accurate and easily applicable test for the diagnosis of lumbosacral spinal cord lesions.

To report a phenotypic variant of lattice corneal dystrophy associated with tw o missense changes, Ala546Asp and Pro551Gln, in the transforming growth factor β induced gene (TGFBI). Experimental study. Genomic DnA was obtained from the proband as well as affected and unaffected family members. Exons 4, 11, 12, and 14 of the TGFBI gene were amplified and sequenced. Additionally, a corneal butto n excised from the proband was examined by light and transmission electron micro scopy. Haplotype analysis was performed on the probands family and members of a previously identified pedigree with the same TGFBI gene missense changes. Bila teral, symmetric, radially arranged, branching refractile lines within and surro unding an area of central anterior stromal haze were noted in the proband. Multi ple polymorphic, refractile deposits were noted in the mid and posterior stroma in both the proband and her daughter. Light and electron microscopic analyses de monstrated amyloid and excluded the presence of deposits characteristic of granu lar corneal dystrophy. Screening of TGFBI exon 12 in the proband and her affecte d daughter revealed two missense changes, Ala546Asp and Pro551Gln (both absent in 250 control chromosomes). Haplotype an alysis suggested that the mutations in this family and in a previously identifie d pedigree reflect a founder effect, rather than an independent occurrence. We p resent a phenotypic variant of lattice corneal dystrophy associated with the Ala 546Asp and Pro551Gln missense changes in exon 12 of the TGFBI gene. A common anc estor appears to account for the missense mutations observed in this pedigree an d in a previously reported family.

目的：探讨具有乙肝背景的肝细胞肝癌（hepatocellular carcinoma,HCC）患者射频消融术（radiofrequency ablation,RFA）术前血清乙型肝炎e抗原（HBeAg）水平与术后肿瘤复发的相关性。方法：回顾性分析2006年6月至2012年6月复旦大学附属中山医院收治的具有乙肝背景的小HCC行RFA治疗的391例患者的临床资料。根据术前HBeAg水平,将患者分为HBeAg阳性组（n=112）和HBeAg阴性组（n=279）。术后定期规律随访,分析RFA术前HBeAg水平和RFA术后肿瘤复发的相关性。结果：HBeAg阳性组术后中位无复发生存期（recurrence-free survival time,RFS）为（23.00±1.99）个月,HBeAg阴性组术后中位RFS为（31.00±3.49）个月,差异有统计学意义（P=0.002）。多因素Cox风险回归分析显示,术前甲胎蛋白（alpha fetal protein,AFP）水平（HR 1.393,95%CI 1.052-1.845,P=0.021）、血清HBv-DnA水平分级（HR 1.402,95%CI1.013-1.939,P=0.041）和HBeAg水平（HR 1.389,95%CI 1.017-1.896,P=0.039）是影响乙肝背景小HCC RFA术后无瘤生存时间的独立危险因素。结论：原发性HCC RFA术前血清HBeAg水平与术后肿瘤复发密切相关,是原发性HCC RFA术后复发的独立危险因素。
