肺气肿并发肺炎的高分辨率CT表现

肺气肿并发肺炎与单纯肺炎的临床和X线表现不同。CT广泛应用于临床后发现,肺气肿并发肺炎的CT和高分辨率CT(HRCT)表现不同于单纯肺炎,本文对一组肺气肿并发肺炎和单纯肺炎病人的CT和HRCT表现进行对比分析,旨在提高对肺气肿并发肺炎的HRCT征象的认识。1资料与方法1.1一般资料临床确诊为肺气肿并发肺炎病人21例,男15例,女6例;年龄41-79岁,平均63.5岁。肺气肿的诊断均符合慢性阻塞性肺疾病诊治规范[1]标准,HRCT上分为小叶中心型、全小叶型和间隔旁型3种亚型。肺炎根据临床症状、体征、影像学表现和实验室检查确诊。除外并发支气管扩…     

巨细细胞性贫血患者骨髓巨核细胞的吞噬现象

已知在正常情况下,巨核细胞无吞噬作用;但在某些病理情况下如自身免疫性溶血性贫血,骨髓硬化症,何杰金氏病、骨髓瘤、急性淋巴细胞性白血病,癌瘤骨髓转移等(其中一例癌转移病人肋骨骨髓中巨核细胞的吞噬率达41%)。但迄今未对此问题给予足够的重视,就我们所查到的文献,国内外仅见三篇有关报道。最近我们在24例巨幼细胞性贫血(简称巨幼贫)患者骨髓中发现巨核细胞吞噬红细     

微波辐射对PC12细胞突触素Ⅰ表达的影响及其机制

AIM: To investigate the effect of microwave radiation on expression and phosphorylation of synapsin I and to discover the mechanism by research on the change of expression of BDNF and its receptor, TrkB. METHODS: PC12 cells were exposed to microwave with average power density being 30 mW/cm(2). HPLC was used to detect the release of amino acids; RT-PCR, Western blot and immunocytochemistry were used to detect the expressions of synapsin I, BDNF and TrkB; immune co-precipitation was used to study the interaction of BDNF and TrkB. RESULTS: It resulted in the decrease of the release of Asp, Glu, GABA and Gly at 1 h (P<0.01) after radiation. Protein of synapsin I was decreased in 9 h-2 d (P<0.01 or P<0.05); its mRNA was decreased in 3-9 h and increased at 1 d (P<0.01 or P<0.05); its phosphorylation was decreased at 3 h, increased at 1 d, and decreased at 2 d again (P<0.01 or P<0.05) after radiation. Protein of BDNF was decreased at 3 h and increased in 1-2 d (P<0.01 or P<0.05); its mRNA were decreased in 3-9 h, increased at 1d, and decreased at 2 d again (P<0.01 or P<0.05) after radiation. Protein of TrkB was increased in 3 h-1 d (P<0.01 or P<0.05); its mRNA decreased at 3 h and 2 d (P<0.01) after radiation. The interaction between BDNF and TrkB was increased in 3-9 h, but decreased in 1-2 d (P<0.01 or P<0.05) after radiation. CONCLUSION: Microwave radiation can induce the decrease of the release of amino acids and the expression and phosphorylation of synapsin I, and the abnormality of expressions and interaction of BDNF and TrkB in PC12 cells. The factors might play a role in the injury and repair of information transmission in PC12 cells.     

冲洗负压吸引法在治疗颌面感染中的应用

近5年来我科对颌面部感染如化脓性颌下淋巴结炎、间隙感染、坏死性筋膜炎等采用了冲洗负压吸引法,经42例病人观察效果良好,脓液清除快,病程缩短。方法:在切开引流时针头接在20ml注射器上。用生理盐水,或3％过氧化氢液,反复冲洗脓腔,同时用吸引器抽吸,直至创腔或创面清洁。如换药时脓液仍多可重复上述操作。根据情况选用引流条。例1 糖尿病患者,周某,女,47岁。因左颞面部及耳后区坏死性筋膜炎并发腮瘘、耳廓感染;入院治疗。体温37.6℃,左头面部肿胀明显,皮肤呈紫红色,创面有大量黄白色粘稠脓液、皮下组织及筋膜大片坏死。化验:白细胞23000。血色素12g％,血糖254mg％,尿糖++++,酮体++。脓液培养有     

亚急性粒细胞白血病口腔粘膜浸润误诊为乳头状瘤1例

亚急性粒细胞白血病口腔粘膜浸润误诊为乳头状瘤１例王丽峰１临床资料患者，男性，１７岁。１９８８年８月２９日因右颊部粘膜肿物诊为乳头状瘤，局部肿块切除。术后５天伤口缝线脱落出血并成粘膜下血肿，重新缝合后４天时再次出血收入院。查体：贫血貌，右颊部粘膜下瘀血...     

腭裂术后患儿呼吸困难的观察与护理

幼儿期行腭裂整形术,宜用气管内插管麻醉,但术后出现呼吸困难,以至窒息并非罕见。近3年来,我科共做腭裂手术44例,其中术后出现呼吸困难的36例,经及时发现,正确处理无1例发生窒息和死亡。一、造成呼吸困难的原因分析 1.喉腔粘膜血管丰富,且与粘膜下层结合较为疏松,喉下腔尤为明显,婴幼儿更为突出。对于年龄较小的幼儿,行气管内插管麻醉时,术者操作不够轻柔或反复多次插管,均易引起喉头水肿。2.术者在手术中,可能多次碰撞插管,以至插管对喉腔多次刺激,导致喉头水肿使本来狭小的喉腔间隙变得更为狭窄,使患儿出现呼吸困难。3.全麻术后,呼吸道
