胸腺瘤的CT观察

５２例经病理学证实的胸腺瘤ＣＴ资料表明，胸腺瘤主要以直接延伸的方式生长，部分胸腺瘤可由近及远地侵犯纵隔诸间隙或（和）类似胸膜间皮瘤一样沿胸膜、心包呈侵袭性生长，只有极少的胸腺瘤可经血行或淋巴途径向远处转移，据此，我们将胸腺瘤分为局限性胸腺瘤与非局限性胸腺瘤两类，这种分类反映了胸腺瘤生长延伸的生物学特性，诊断标准易于掌握，对指导治疗方针的制订及预后的估计有重要的参考作用。     

颈椎保健理疗仪的研制

本文介绍了一种适合治疗各种类型颈椎病的颈椎保健理疗仪。它是由颈椎按摩装置、热疗装置和颈椎牵引装置构成。治疗颈椎病时,先利用颈椎按摩、热疗装置对颈部进行揉捏推拿、振动按摩、热疗;然后利用牵引装置对椎间小关节紊乱、椎间隙狭窄（椎间盘病变）等疾病进行牵引治疗。     

Intravenous immunoglobulin in the management of severe early onset red blood cell alloimmunisation

Our objective was to assess the effect of maternal intravenous immunoglobulin (IVIG) administration for severe red blood cell (RBC) alloimmunisation on fetal outcomes. This is a case–control study. Women with a history of severe early onset alloimmunisation resulting in fetal loss in a previous pregnancy and high anti-D or anti-K antibody titres received IVIG in a subsequent pregnancy. We assessed gestational age at first transfusion and fetal outcomes in the subsequent pregnancy and compared these with the outcomes in the previous pregnancy. The most responsible antibody was anti-D in 17 women and anti-K in two others, whilst seven had more than one antibody. In all, 19 women received IVIG in 22 pregnancies, two of which did not even need an intrauterine transfusion (IUT). For previous early losses despite transfusion, IVIG was associated with a relative increase in fetal haemoglobin between treated and untreated pregnancies of 36.5 g/L (95% confidence interval 19.8–53.2, p = 0.0013) and improved perinatal survival (eight of eight vs. none of six, p = 0.001). For previous losses at <20 weeks, it enabled first transfusion deferral in subsequent pregnancies to at least 19.9 weeks (mean 23.2 weeks). Overall, IVIG decreases the severity of haemolytic disease of the fetus and newborn and allows deferral of the first IUT to a safer gestation in severe early-onset RBC alloimmunisation and rarely may even avoid the need for IUT entirely.
