离体不同时间血痕的肉眼和扫描电镜观察

对离体不同时间血痕进行肉眼和扫描电镜观察，获得了血痕形态结构变化的初步认识．结果随时间延长，血痕逐渐干燥、龟裂，电镜下纤维蛋白网消失，其超微结构变化观察有助于血痕经过时间的推断．     

肺内小病灶CT表现及其病理基础的研究：附76例分析

本文对７６例肺内小病灶（直径≤３ｃｍ）病例进行了ＣＴ－病理对照研究。结果表明，短毛刺征，深分叶征、棘状突起征、空泡征、血管集束征，胸膜凹陷征等对于诊断周围型小肺癌有重要临床价值；而尖角征、局限性胸膜肥厚粘连对诊断良性病灶有意义。本文重点讨论了血管集束征的定义，ＣＴ表现及病理基础；并就有争议的胸膜凹陷征提出一些粗浅的看法。旨在提高肺内小病灶良恶性诊断的准确率

重组促红细胞生成素对腹膜透析患者心功能的影响

目的　了解基因重组人促红细胞生成素 (r HuEPO)对持续性非卧床腹膜透析 (CAPD)患者心室结构及功能的影响。方法　 32例CAPD伴高血压患者 ,其中 1 6例应用降压药物控制血压 ,同时应用r HuEPO纠正贫血 ,1 6例单用降压药物 ,随访 6个月。结果　两组治疗前后差值比较 ,治疗组的LVPWT、E/A与对照组比较有显著差异(P <0 .0 5 )。结论　长期纠正贫血和控制血压有利于透析患者左室结构及功能异常的逆转     

亚低温对大鼠脑损伤后脑组织炎性反应的影响

目的探讨颅脑外伤后早期应用亚低温治疗对脑组织炎性反应的影响。方法采用Feeney自由落体改良模型,设定对照组、颅脑外伤模型组及亚低温组,每组再根据伤后不同生存时间随分为3个亚组。取伤灶脑组织检测髓过氧化酶(MPO)活性,做细胞间黏附子-1(ICAM-1)免疫组化染色,光镜下计数ICAM-1阳性血管数。结果亚低温组各时间点伤灶区ICAM-1阳性血管数明显低于颅脑外伤模型相应时间点(P<0.01)。亚低温组各时间点MPO活性均明显低于颅脑外伤模型组相应时间点(P<0.01)。结论亚低温治疗能明显减少伤灶区白细胞浸润及ICAM-1的表达,有助于改善颅脑外伤后脑组织炎性反应引起的继发性脑损伤。     

支气管结核在纤维支气管镜下治疗方法的探讨

目的 :探讨支气管结核在纤维支气管镜下治疗的方法及价值。方法 :对 2 5例支气管结核病人 ,在全身抗结核治疗的同时分别实施镜下注药治疗、微波接触式辐射治疗和球囊扩张术 局部注药治疗。结果 :在全身抗结核治疗的同时运用上述几种镜下治疗方法 ,支气管局部病灶较镜下治疗前均有明显好转。结论 :利用纤维支气管镜对支气管结核病人进行局部治疗 ,可加快病灶的吸收和症状的改善 ,值得推广应用

特异性血小板抗体检测的实验研究

目的　建立一种简易、特异性强的血小板抗体检测方法。方法　利用磷酸氯喹溶液对血小板进行处理 ,去掉血小板相关抗原 (HLA抗原 ) ,用只含特异性抗原的血小板包被聚乙烯板来捕获血小板抗体。结果　与常用的SEPSA和淋巴细胞毒实验 (LCT)比较 ,该方法只表现血小板特异性抗体反应。结论　本方法能够鉴别血小板相关抗原的抗体和血小板特异性抗原的抗体 ,为临床血小板减少疾病的鉴别诊断、非溶血性发热反应和血小板输注无效的原因提供有用的参考依据     

The correlation between TNF-α, IL-6 in cervical mucous during follicular development and ovulation stimulation in different protocols

Objective To investigate the correlation between TNF-α and IL-6 levels in cervical mucous during follicular development and ovulation stimulation in different protocols.Methods 36 infertile women were set up as experimental groups,divided into CC, HMG, IVF-ET group,each group consisted of 12 infertile women and 15 women with normal menstrual cycles were choiced as control group.Cervical mucous during follicular phase, luteal phase and ovulation phase were collected.TNF-α, IL-6 levels in cervical mucous were measured by radioimmunology assay (RIA).Follicular development were monitored by transvaginal ultrasonagraphy.Results (1) TNF-α levels in cervical mucous of experimental groups and control group were periodically various among the reproductive cycle.It increased during follicular phase, reached to peak during ovulation phase, and decreased during luteal phase (P＜0.05).IL-6 levels had no obvious periodical changes.(2) Compared with CC and control group, levels of TNF-α,IL-6 in HMG and IVF-ET group were significantly higher (P＜0.05).(3) Levels of TNF-α and IL-6 in cervical mucous were positively correlated with the dominant follicle diameter (r=0.261, r=0.192 respectively,P＜0.05).(4) TNF-α and IL-6 showed positive correlation in the reproductive cycle (r=0.782,P＜0.05).Conclusions (1) TNF-α level shows a cyclic change in the reproductive cycle and peaks during ovulation,whereas IL-6 level does not.(2) TNF-α and IL-6 may play a certain role in the process of follicular development and ovulation.(3)The levels of TNF-α and IL-6 are up-regulated by gonadotrophic hormone.(4) TNF-α and IL-6 may have coordination properties and participate in the same biological effects.
