低出生体重儿血锌值及其动态观察

为了比较５２例低出生体重儿血锌值，生后每月随访外周血锌至９个月，将调查对象分为３组，根据简易ＡＡＳ测定方法，将经过特殊处理的标本采用ＳＡＳ／７２７原子吸收分光光度计测定血锌值。结果：低出生体重儿脐血红细胞锌。外周血锌值均低于正常足月儿；低出生体重儿母亲血红细胞锌值低于正常足月儿母亲。对低出生体重儿９个月的随访表明，其外周血锌值仍处在低水平。提示：锌能影响胎儿宫内生长，低出生体重儿应补充足量的锌。

肿瘤坏死因子在妊高征发病中的作用

目的：探讨肿瘤坏死因子（ＴＮＦ）在妊高征发病中的作用及其对胎儿生长的影响。方法：应用放射免疫法对正常晚期妊娠妇女１６例（对照组）及妊高征患者４６例（妊高征组）的血浆、羊水和新生儿脐血中ＴＮＦ进行检测。结果：分娩前妊高征组血浆ＴＮＦ水平较对照组高，以中、重度妊高征者增高显著（Ｐ＜０．０５）；产后７２小时妊高征组血浆ＴＮＦ水平下降，与对照组差异无显著性。对照组及轻度妊高征者新生儿脐血ＴＮＦ水平与母血接近，羊水ＴＮＦ水平明显低于母血（Ｐ＜０．０５）；中、重度妊高征者脐血和羊水ＴＮＦ水平均较母血低（Ｐ＜０．０５；Ｐ＜０．０１）。新生儿脐血、羊水中ＴＮＦ水平在两组间差异无显著性。在中、重度妊高征者中，合并胎儿生长迟缓者其羊水和新生儿脐血ＴＮＦ水平明显高于未合并胎儿生长迟缓者。结论：ＴＮＦ可能作为母体对胎儿抗原的异常免疫反应的重要介质，在妊高征的发病中起一定作用。     

Repeat Chlamydia trachomatis infection in women: analysis through a surveillance case registry in Washington State, 1993-1998

Repeat infections with Chlamydia trachomatis are associated with increased risk for long-term sequelae. The authors analyzed the frequency and predictors of repeat chlamydial infection by using a population-based chlamydia registry in Washington State and evaluated whether women would seek care at the same clinic for repeat infections. Among 32,698 women with an appropriately treated initial chlamydial infection during 1993-1998, 15% developed one or more repeat infections during a mean follow-up time of 3.4 years. Among women less than age 20 years at the time of initial infection, 6% were reinfected by 6 months, 11% by 1 year, and 17% by 2 years. Young age was the strongest predictor for one and two or more repeat infections after controlling for the length of follow-up and other variables. Only 36% of the repeat infections were diagnosed at the same clinical setting as the initial infection, and 50% were diagnosed at the same type of clinic. Adolescent girls had the least consistency in the source of care for chlamydia. This study suggests that efforts to prevent repeat chlamydial infection in young women remain an urgent public health priority and that the burden of repeat infection may be substantially higher than estimates from clinic-based studies.

大白鼠减压缺氧性肺水肿的形态计量研究

实验采用形态计量方法探讨大白鼠模拟６ｋｍ减压缺氧、４、８和１２ｈ条件下间质性肺水肿（ＩＰＥ）和冷水游泳负荷后８ｋｍ减压缺氧３－６ｈ肺泡性肺水肿（ＡＰＥ）的发生情况。结果表明，６ｋｍ减压缺氧各组，肺细支气管动脉周围腔明显扩大，冷负荷后缺氧肺水肿的面积较单纯８ｋｍ减压缺氧组和单纯冷负荷后缺氧组有显著性差别。     

骨巨细胞瘤的生物学行为研究

本文对骨巨细胞瘤（ＧＣＴ）的传统组织学分级与其生物学行为不甚相符的原因进行了研究。采用５１例ＧＣＴ为研究对象，以１３例骨囊肿（良性）和１５例骨肉瘤（恶性）为对照组，采用图像分析仪（ＩＡＴ）对细胞核（ＧＣＴ取基质细胞核），进行了形态计量研究（８项参量），ＤＮＡ含量，ＤＮＡ倍体类型研究，及术后复发病例的ＤＮＡ倍性与其传统分级的比较研究。结果经统计学处理发现ＧＣＴⅠ级和Ⅱ级之间无显著差别，且它们的生物学属性在潜在恶性和低度恶性范畴。研究还揭示ＧＣＴ的ＤＮＡ≥５ｃ细胞数超过７％者系术后复发、转移的高危病例。
