多部位采血快速血糖仪的临床应用

目的:探讨多部位采血快速血糖仪检测大鱼际毛细血管葡萄糖用于糖尿病患者血糖监测的准确性及优缺点。方法:对我科47例住院糖尿病患者在知情同意后进行血糖检测。行正常餐实验,在空腹时和正常餐后2h分别采静脉血用葡萄糖氧化酶法测定血糖、采手指血用乐康全血糖仪测定血糖、采手掌大鱼际血用Free- style多部位采血血糖仪检测血糖;同时进行采血疼痛感和使用方便性的主观调查,分最好、好、一般和差4级,转换为数字1、2、3、4进行评价。结果:3组的空腹血糖值差异无显著性(P>0.05);餐后2h血糖差异有显著性(P<0.05)。3组的空腹血糖及餐后2h血糖均有良好的线性相关(r=0.759～0.795,P<0.001)。3个部位的测试结果间均呈良好的线性相关,决定系数(R~2)=0.576～0.651(P<0.001)。两种血糖仪的使用方便性无明显差异.指尖采血的疼痛性要强于手掌大鱼际采血(P<0.05)。结论:多部位快速血糖仪(Freestyle)手掌大鱼际采血检测血糖的结果可靠,是糖尿病患者长期监测血糖的一种较为准确、方便、痛苦较少的方法。     

回盲部恶性肿瘤的诊治

目的：分析回盲部恶性肿瘤的诊断和治疗过程，总结经验．以期提高早期确诊率和患者生存率。方法：回顾性分析近5年53例住院治疗的回盲部恶性肿瘤患者的临床资料。结果：53例患者中腺癌、黏液腺癌50例，恶性淋巴瘤3例。首次确诊率为75．5％。误诊或延迟诊断的疾病主要为阑尾炎、阑尾脓肿，胆囊炎、胆石症、下消化道出血、贫血待查等。结论：60岁以上的老年患者为回盲部恶性肿瘤的主要人群，肿瘤类型主要为腺癌。尽管首发症状缺乏特异性，但提高警觉性，详细询问病史，通过大便隐血试验、钡灌肠或气钡双重造影、纤维结肠镜检查仍能有效的提高首次确诊率，积极手术冶疗，可显著改善患者的预后。     

Solitary fibrous tumor of the inguinal region

Solitary fibrous tumors (SFT) have recently been established to be of mesenchymal origin. Although there are numerous reports of SFTs arising from the pleura, reports of the tumor arising from extrapleural sites are comparatively rare [Fletcher CDM, Unni K, Mertens F (eds) World Health Organization classification of tumors, pathology & genetics, tumors of soft tissue and bone. IARC Press, Lyon, pp 86–901, 2002]. We report a case of SFT arising in the inguinal region.     

磁刺激运动诱发电位在腰椎间盘突出所致的腰骶神经根病变中的应用研究

在35例有L5和／或S1神经根损害表现的腰椎间盘突出患者腰椎区进行磁刺激运动诱发电位（MEP）检查，测定、记录胫前肌、展肌和小趾展肌MEP的起始潜伏期（OL）。结果显示，35例中至少有一条总侧肌肉MEP异常33例（94．3％）。在L4－5椎间盘突出中，以胫前肌的MEP异常为主；在L5－S1椎间盘突出中，以小趾展肌的MEP异常为主。表明腰椎区MEP检查对腰椎间盘突出所致的腰骶神经根病变较为敏感，可为临床诊断提供可靠依据并有助于定位诊断。     

Suppression of the jaw-opening reflex by periaqueductal gray stimulation is decreased by paramedian brainstem lesions

Electrical stimulation of the midbrain periaqueductal gray region (PAG) suppresses the tooth pulp-evoked jaw-opening reflex (TP-JOR). In the present study the pathways that mediate this suppression were investigated by placing brainstem lesions in lightly anesthetized cats. Parasagittal lesions that interrupted the afferent and efferent connections of the medullary and pontine raphe nuclei attenuated (but did not abolish) suppression of the TP-JOR evoked by PAG stimulation. This result provides further evidence that medial brainstem structures partially mediate the effects of PAG stimulation in the trigeminal system.

腰神经通道卡压综合征病因的探讨

为了探讨腰神经通道狭窄的病因，我们对２２４例腰椎间盘突出及腰椎管狭窄症患者进行了腰神经通道探查手术，结果发现其病因以腰部组织变性为主。除外伤及反复慢性腰部损伤引起腰部病变外，活动少，或很少进行腰部锻炼，体形肥胖也是引起腰神经通道狭窄日趋加重的致病因素。在治疗时强调不只满足于切除突出的椎间盘，应沿神经通道探查，清除一切卡压神经根的病变组织才能获得较好的治疗效果。我们随访１９７例，平均随访３ａ，优良率９３５％。     

The normally expressed κ immunoglobulin light chain gene repertoire and somatic mutations studied by single-sided specific polymerase chain reaction (PCR); frequent occurrence of features often assigned to autoimmunity

The expressed human κ light chain gene repertoire utilized by healthy individuals was studied by two different single-sided specific PCR techniques to avoid bias for certain V genes. A total of 103 rearranged κ sequences from peripheral blood mononuclear cells from healthy individuals were cloned from cDNA and assigned to the Vκ and Jκ germ-line genes with the closest overall homology. The use of cDNA rather than genomic DNA focused the analysis on activated B cells rich in mRNA. Accordingly, the sequences represented the applied repertoire and almost all were somatically mutated. V genes from the Jκ-proximal duplication unit of the κ locus were almost exclusively used. A total of 65% of the sequences could be assigned to four or five genes: A27 (humkv325), L6 (Vg), L2 (humkv328), and A3 and/or A19. N additions and P nucleotides were quite common and found in 32% and 21% of the sequences, respectively. Extended CDR3s more than nine residues in length were found in 18% of the sequences, and in 71% of cases this was due to insertion of an extra proline residue. This proline was usually explained from the germ-line sequences involved. These results are in good agreement with those of previous repertoire studies using potentially V-gene-biased techniques. Thus, it is clear that restricted V-gene usage, common N and P additions, and extended CDR3 regions are normal features and not, as has been claimed, characteristics of pathological autoantibodies.
