已婚育龄妇女避孕措施变化趋势分析

目的:了解已婚育龄妇女避孕措施的变化趋势,为指导计划生育服务工作提供科学依据。方法:收集1983~2005年苏州市已婚育龄妇女避孕方法的资料,并用统计软件对其变化趋势进行了分析。结果:已婚育龄妇女节育率在88.38%~92.94%范围波动,长效避孕措施现用率从75.19%下降至71.27%,而短效避孕措施从12.86%上升至17.11%。宫内节育器的现用率从50.09%上升到66.50%;避孕套从1.94%上升到14.21%;其他避孕方法的现用率均呈下降趋势,其中女性绝育现用率从24.42%下降到4.50%。结论:节育率维持在较高水平;长效避孕措施现用率下降而短效避孕措施现用率上升;避孕方法使用趋于多样化,需要提供满足个性化需求的指导和服务。     

肝素治疗小儿肾病综合征的远期效应

采用无抗凝作用剂量肝素皮下注射治疗小儿肾病综合征２５例，观察了近期疗效与１２～２４月后对皮质激素或环磷酰胺（ＣＴＸ）治疗反应的关系．结果表明，近期对肝素治疗显效但复发以及有效者，今后用激素或ＣＴＸ治疗均可达完全缓解，无效者则效果较差．本文结果表明，肝素治疗的近期疗效可用于预测肾病患儿的远期预后．

淋巴因子水平改变与妊高征的关系

近年来的研究结果发现由Th1/Th2细胞分泌的淋巴因子与妊娠高血压综合征联系密切 ,可能参与了其病因及病理生理过程 ,对它的深入研究有利于妊娠高血压综合征诊断、治疗水平的提高     

吸入麻醉药对人血浆和血小板血栓素B2生成与血小板聚集的影响

目的：探讨吸入麻醉剂氟烷、安氟醚和异氟醚对人血浆血栓素Ｂ２（ＴＸＢ２），血小板ＴＸＢ２生成与血小板聚集的影响。方法：血浆ＴＸＢ２和血小板ＴＸＢ２的生成量用放免分析法测量，血小板聚集率用比浊法测量。结果：吸入１ＭＡＣ氟烷３０分钟后，血浆ＴＸＢ２浓度、二磷酸腺苷（ＡＤＰ）和肾上腺素（Ｅ）诱导的血小板ＴＸＢ２生成量与血小板聚集率显著下降，吸入１ＭＡＣ安氟醚３０分钟后，血浆ＴＸＢ２浓度和血小板ＴＸＢ２生成量与血小板聚集率亦显著下降，其降低的程度比氟烷轻。吸入１ＭＡＣ异氟醚对上述指标无明显影响。血小板ＴＸＢ２生成的减少与血小板聚集率的下降呈显著正相关。结论：氟烷显著抑制血小板聚集，安氟醚次之，异氟醚对血小板聚集无明显影响。其机制可能与氟烷和安氟醚通过抑制血小板上血栓素Ａ２受体的亲和力，降低ＡＤＰ和Ｅ诱导的血小板ＴＸＢ２的生成有关。     

支气管肺泡灌洗液、血清、尿液中CEA测定对肺癌诊断价值的研究

应用放射免疫方法联合检测支气管肺泡灌洗液(BALF)、血清、尿液中癌胚抗原(CEA)含量,结果显示:肺癌患者BALF、血清、尿液中CEA均有不同程度的升高,与结核及肺良性疾病组间有显著差异(P<0.01)。其阳性率分别为63.64％,57.38％,27.58％,以BALF阳性率为最高,这对肺癌的诊断及判断预后提供了方便可行的检测手段。

The prevalence of LRRK2 Gly2385Arg variant in Chinese Han population with Parkinson's disease.

We conducted a case-control study to determine the prevalence of the LRRK2 Gly2385Arg variant in patients with Parkinson's disease in Han population in mainland China. Heterozygous LRRK2 Gly2385Arg variant was identified in 14 of 235 patients with Parkinson's disease (5.69%), but not in 214 unrelated healthy controls. Multivariate analysis indicated the frequency of Gly2385Arg variant in the female patients with early age at onset is higher than their male counterparts. The founder haplotype analysis showed the variant carriers shared the same founder. Clinically, the LRRK2 Gly2385Arg carriers presented with classical Parkinson's disease symptoms. Our study indicates that the LRRK2 Gly2385Arg variant is a potential ethnic-specific genetic risk factor of Parkinson's disease within Chinese Han ethnicity.     

Role of mast cells and monoamines in the thrombocytopaenia and mortality elicited by tumour necrosis factor in mice.

We explored the thrombocytopaenia elicited by the i.v. injection of mouse recombinant tumour necrosis factor (TNF) in mice. Injection of 10 micrograms of TNF led to a thrombocytopaenia (evident after 0.5 hr) which was caused by decreased platelet survival, as seen by the injection of labelled platelets. TNF-induced thrombocytopaenia was not prevented by heparin, nor by depletion of either fibrinogen or C'. TNF-induced thrombocytopaenia was markedly attenuated in mice treated with reserpine, an agent that depletes monoamines from mast cells and other cells, and in the mast-cell-deficient WWv mice. In vitro, TNF elicited a modest release of monoamine from peritoneal mast cells and from a mast cell line. When mice are injected with 3H-serotonin (3H-5HT) before TNF, TNF injection increased the plasma 3H-5HT content 1 hr later, modifications absent in reserpine pretreated or mast-cell-deficient mice. 3H-5HT content of the small intestine was markedly depleted in TNF-injected mice, suggesting that this organ is the source of the plasma 3H-5HT. Drop in body temperature and mortality induced by TNF were also attenuated in mast-cell-deficient, and in reserpine pretreated mice. These results indicate that TNF can induce a release of monoamines from mast cells, mainly from those of the small intestine, a process that contributes to TNF-induced thrombocytopaenia and mortality.
