脊髓损伤中SEP的诊断价值

对７１例脊髓损伤患者入院时行短潜伏期体感诱发电位（ＳＬＳＥＰ）检测，根据电反应、潜伏期及波峰变化分为３组：Ⅰ组电反应正常；Ⅱ组各类波形异常；Ⅲ组完全无电反应。经过平均１４．５个月的随访（采用Ｆｒａｎｋｅｌ截瘫分级法），发现在５０例完全性截瘫患者中，ＳＬＳＥＰ无电反应者的截瘫恢复，手术组与非手术组无差异，而ＳＬＳＥＰ异常组手术后截瘫恢复明显优于非手术组。笔者认为，ＳＬＳＥＰ无电反应者无手术价值，而Ｓ     

红藻酸致大鼠癫痫模型短潜伏期体感诱发电位分析

目的：了解癫痫发作时大脑神经元的功能状态。方法：２０只红藻酸致痫大鼠于癫痫发作前、急性发作期、慢性发作期经正中神经刺激对短潜伏期体感诱发电位（ＳＬＳＥＰ）进行测定。结果：大鼠ＳＬＳＥＰ波形为一小的Ｎ１波后接一大的Ｐ１波；癫痫急性发作期改变为Ｎ１、Ｐ１波的ＰＬ延长，波幅降低，有３例波形缺失；慢性发作期仅Ｐ１波的Ｐ１较前缩短。结论：癫痫急性发作期Ｎ１、Ｐ１波的改变与兴奋性氨基酸的神经元毒性作用及继发性缺血、缺氧致神经元损伤有关。慢性发作期Ｐ１波缩短的机理有待进一步研究。

体感皮层诱发电位对牵张性脊髓损伤的监护作用

目的探索体感皮层诱发电位（ＳＣＥＰ）对牵张性脊髓损伤的监护作用。方法采用４０只日本大耳白兔，随机分为对照组、ＳＣＥＰＰ１波下降３０％组、５０％持续５分钟组、５０％持续１０分钟组。通过对实验动物进行运动功能评价、生化指标测定及组织形态学观察，研究ＳＣＥＰ对牵张性脊髓损伤监护的可靠性。结果ＳＣＥＰＰ１波幅随脊柱撑开程度增加而下降，动物后肢运动功能障碍率明显增大，５０％组可见脊髓内血管痉挛，狭窄及破裂出血。结论（１）ＳＣＥＰ的Ｐ１、Ｎ１波幅变化较其潜伏期的变化更能准确地反映脊髓功能的改变。（２）Ｐ１波幅下降３０％无脊髓功能损害。（３）Ｐ１波幅下降５０％，５分钟内除掉撑开作用，所产生的轻度脊髓功能障碍可在短期内恢复；如撑开时间超过５分钟，将产生不可逆的脊髓功能损害。

Optimization of the system of medical service of students of Cadet Schools of the Ministry of Defense of the Russian Federation

One of the factors of the successful military career guidance Cadet schools students is preserving and promoting their health. Medical support of children and adolescents aged 10-17 years should include the full range of medical and preventive measures defined for this group. The state of providing outpatient care for pupils at the Cadet School in St. Petersburg was studied. These results show that full medical care in accordance with the standards can be based only on children's health clinics. It is important that the organization of medical support pupils cadet schools should be cooperate with civilian health care.

Estimation of accumulated dose of radiation by method of ESR-spectrometry of dental enamel of mammals

ESR-spectrometry was used to investigate radiation-induced paramagnetic centers in enamel of mammals: carnivores (polar bear and fox), ungulates (reindeer, European bison, moose), and man. Values at half the microwave power saturation of the radiation signal, P_1/2, evaluated at room temperature, was found to range from 16 to 26 mW for animals and man. A new approach to discrimination of the radiation induced signal from the total ESR spectrum of reindeer enamel is proposed. ‘Dose-response’ dependencies of enamel of different species mammals were measured within the dose range from 0.48 up to 10.08 Gy. Estimations of ‘radiosensitivity’ enamel of carnivores and ungulates showed good agreement with radiosensitivity enamel of man by ESR method.     

Analysis of the results of the international comparison of activity measurements of a solution of Fe

The results of an international comparison of activity measurements of a solution of ⁵⁵Fe organized by the BIPM in 2005 are reported and analysed. This exercise, which follows the procedures of the CIPM mutual recognition arrangement to update older comparisons, is a renewal of the comparison organized by the BIPM that took place in 1978. A EUROMET comparison was organized in 1996 specifically to compare activity measurements of a ⁵⁵Fe solution by means of liquid-scintillation techniques. Results of these three comparisons are presented and discussed in this paper.

The radionuclide solution was provided by the NPL, which also distributed the samples to the participants. The activity of the ampoules was measured by 16 laboratories using 12 methods producing 25 results. Some general considerations on uncertainty assessments pertaining to the different techniques used are drawn. The outcome of four different estimators is compared from which the presence of at least one outlier can be confirmed. Further measurements should be made to try to reduce the discrepancy between the results. To date the outcome of the present comparison does not show an improvement to that of the 1996 comparison.     

Evaluation of the results of various technics of non-surgical therapy of varicocele

A new method of non-surgical treatment of varicocele syndrome is described: it consists in sclerotherapy of spermatic vein by trans-femoral percutaneous catheterization with balloon-catheters. In 8 cases venous thrombosis has been induced by direct electric clotting. The techniques and a 6 months follow-up are discussed. It is pointed out that this procedure should be considered as the method of choice for tubular lesions and sub-fertility prophylaxis in young people and in childhood.     

延迟性脾破裂误漏诊原因分析

目的探讨延迟性脾破裂误漏诊原因和预防措施.方法回顾性分析总结12例延迟性脾破裂中的诊断和误漏诊的经验与教训.结果本组延迟性脾破裂的误漏诊5例(41.66%).对多发伤与脾破裂并存可能认识不足,外伤史轻微或伤员隐瞒外伤史,缺乏腹痛-缓解-突然再腹痛的典型病史,缺乏“对冲性脾破裂”力学分析和整体化诊断思路等为其误漏诊的主要原因.结论详细的外伤史和全面系统检查,重视腹以外多发伤掩盖腹内脏器伤及延迟性脾破裂可能.确立外伤-腹内脏器伤-脾破裂整体化诊断思路.不间断地辅以B超检查脾形态学变化和腹内有无积液,腹腔穿刺确定有无血腹、X线胸腹部检查观察左侧胸肋角和膈肌运动情况、必要时CT检查以尽早发现脾包膜下血肿,降低延迟性脾破裂误漏诊率.
