流式细胞光度术在鼻咽癌上皮样细胞株细胞周期动力学研究中的应用

本实验应用流式细胞光度术研究鼻咽癌上皮样细胞株（ＣＮＥ）的细胞周期动力学。结果发现ＣＮＥ细胞仍保持原代细胞的ＤＮＡ含量水平（超三倍体和亚四倍体），随着细胞接种时间的延长细胞周期中Ｇ０／Ｇ１时相细胞的百分数逐渐升高，而Ｓ％和Ｇ２＋Ｍ％则逐渐降低。该项研究还发现随着孵育时间的延长，细胞周期中各时相细胞的运动均逐渐延缓，其中以Ｇ０／Ｇ１和Ｇ２＋Ｍ时相细胞的运动减慢较为明显。     

尿毒症患者的血小板聚集功能变化及血液透析的影响

本文应用 ADP、肾上腺素及复合诱聚剂对30例慢性肾功能不全(尿毒症期)病人的血小板聚集功能进行了检测,其中5例在血液透析前后分别测定。结果表明尿毒症患者血小板聚集功能障碍,血液透析有助于改善血小板功能。通过相关性检验,发现尿毒症病人的血小板聚集率与血肌酐值呈负相关性,其意义尚需进一步探讨。     

血清中白细胞介素6和白细胞介素8水平在肝病检测中的临床应用

目的:血清中IL-6和IL-8的含量是临床检验中的重要指标,本实验主要对肝癌患者血清的IL-6和IL-8的水平进行了统计分析,为进一步临床监测提供依据。方法:对86份肝癌患者血清进行检测,同时收集30份正常血清和35份肝硬化患者血清作为对照比较。结果:肝癌患者血清中IL-6水平[(0.197±0.041)ng/ml]显著高于对照组(正常组的0.159±0.038;肝硬化组0.185±0.026);肝癌患者血清中IL-8水平[(0.463±0.127)ng/ml],显著高于对照组(正常组的0.354±0.113;肝硬化组,0.386±0.102)。结论:血清中IL-6、IL-8水平可以作为肝癌的临床监测指标。     

Gadolinium-based balloon angioplasty for pulmonary artery stenosis in an infant with a right isomerism.

We report here the first described case of utilizing gadolinium-based contrast material as the contrast agent during a catheter intervention treatment for pulmonary artery stenosis. The patient, a male infant with complex heart disease associated with a right isomerism, had a history of severe allergic reaction to iodine-containing contrast agents. A combination of digital subtraction angiography and a gadolinium contrast agent, however, provided us with good-quality images both before and after balloon angioplasty without any associated complications. This method should therefore be considered as an alternative angiographic procedure in children with a high risk of iodine-related allergic complications.     

颈椎不稳症的影像诊断(附50例报告)

目的探讨颈椎不稳症的影像学诊断。方法回顾性分析50例经临床证实的颈椎不稳症患者的X线平片、CT和MRI检查资料。结果50例中上颈椎不稳16例,其中,寰枕关节不稳2例,表现为枕底—齿突线和斜坡—齿突线不连续,14例为寰枢关节不稳,其中,寰枢关节脱位7例;下颈椎不稳34例,其中,前屈不稳20例,后伸不稳14例。结论X线平片、CT和MRI综合分析能对颈椎不稳症作出准确的诊断。     

Application of trans-abdominal chorionic villus sampling in prenatal diagnosis of chromosomal diseases in first trimester of gestation

Objective:To evaluate the feasibility and safety of prenatal diagnosis by traneabdominal chorionic villus sam-pling(TA-CVS)via the guidance of B-mode ultrasound in the first trimester of gestation.To explore the technique of long time culture and chromosome preparation of villi in early pregnancy.To evaluate the feasibility of the above techniques in the application of the prenatal cytogenetic diagnosis.Methods:One hundred and thirty-five singleton pregnancies at risk were referred from January 2001 to Decem-ber 2007.Results:The average maternal age was 35.2 years.TA-CVS was performed in the 10～13th weeks of gestation and the average gestational age was 10.89 weeks.All attempts at sampling were successful.The rate of operation-associated fetal loss was 0.74%.The failure rate of prenatal diagnosis because of inadequate amount of specimen was 0.The average culture time was 5-7 days.The success rate of the cell culture was 98.5%.No maternal con-temination and bacterial contamination happened.Fifteen cases of abnormal karyotype and one case of confined pla-cantel mosaiciem were diagnosed.Conclusion:TA-CVS appears to be safe and feasible and might to be offered in the prenatal diagnosis in the first trimester of gestation.The technique of long time culture and chromosome preparation of villi is stable and reliable.It is feasible to apply these techniques in the clinical practice of prenatal cytogenetic diagnose in the early pregnancy.
