前列腺素E1对大鼠肝脏缺血再灌注损伤的保护作用

目的 探讨前列腺素E1（PGE1）对肝脏 因再灌注损伤的保护作用。方法 制作常温下大鼠部分肝叶缺血再灌注模型，于缺血前经门静脉给予PGE1，45min后恢复血流灌注，并于1h后取门静脉血测定血清谷草转氨酶（GOT）、谷丙转氨酶（GPT）、乳酸脱氢酶（LDH）、肿瘤坏死因子－α（TNF－α）及内皮素1（ET－1），同时取缺血肝叶行病理组织学检查。结果 缺血再灌注组GOT、GPT、LDH及TNF－α和ET－1均明显高于正常对照组，PGE1组则明显低于缺血再灌注组。PGE1组的肝脏病理组织学改变明显轻于缺血再灌注组，并接近正常对照组。结论 PGE1对肝缺血再灌注具有保护作用。     

甲状腺肿瘤X线造影与超声检查对比分析

本文报告了经手术病理证实的53例甲状腺肿瘤,均作了甲状腺造影和B超检查.通过比较分析,我们认为造影对确定肿瘤的良、恶性以及延伸到胸骨后的异位甲状腺肿瘤有其优越性,是一项有效的检查方法;超声则能准确地判断肿瘤的囊、实性,适合碘过敏患者的检查.两种检查各有特点,配合使用有利于对甲状腺肿瘤的诊断和治疗.

利凡诺联合小水囊在中期引产中的应用

人工促宫颈成熟诱导分娩是妇产科的一个重要课题，特别是妊娠中期的宫颈坚硬、宫口紧闭，往往给终止妊娠带来一定的困难。为了提高引产质量，避免并发症的发生，在引产过程中必须对促宫颈成熟给予足够的重视。我院应用利凡诺联合自制小水囊法中期引产52例，宫颈评分提高，从引产到胎儿娩出的时间缩短。现报告如下。     

传染性非典型肺炎患者泪液和血液中特异性抗体检测的对比研究

目的：通过传染性非典型肺炎(SARS)患者泪液病毒特异性抗体的检测，寻找SARS病毒是否通过泪液或眼结膜传播的理论依据，了解泪液和血液中SARS病毒特异性抗体检测结果的一致性程度。方法：用酶联免疫吸附法(ELISA)检测18例不同病程的SARS患者泪波及血清SARS病毒特异性抗体。结果：18例SARS患者泪液中的特异性IgM类和IgG类抗体均为阴性，而同组患者有13例其血液中的特异性IgM类和IgG类抗体呈阳性。结论：SARS病毒可能不通过泪液或结膜传播。     

Prognostic role of alveolar-arterial oxygen pressure difference in acute pulmonary embolism.

BACKGROUND: This study investigated the utility of the alveolar - arterial oxygen pressure difference (AaDO (2)) in predicting the short-term prognosis of acute pulmonary embolism (PE). METHODS AND RESULTS: This study retrospectively enrolled 114 consecutive patients with acute PE, diagnosed by either spiral computed tomography or high probability ventilation - perfusion lung scans. During the first 24 h of admission, all patients had initial artery blood gas collected under room air. Patient exclusion criteria were chronic lung disease, septic emboli, and moderate and low probability lung scans. Patients were assigned to 2 groups based on either 30-day death or a 30-day composite event. Receiver operating characteristic analyses was used to determine the AaDO(2) cut-off value for predicting primary and composite endpoints. Statistical analysis demonstrated significant differences in AaDO(2) between the 30-day composite endpoint group and the 30-day composite event-free survival group (p=0.012). The AaDO(2) had a strong trend between the 30-day death group and the survival group (p=0.062). The best cut-off value for AaDO(2) was 53 mmHg and using this, the positive predictive value for 30-day death was 25% and the negative predictive value was 92%. For the 30-day composite endpoint, the positive predictive value for AaDO(2) was 35%, and the negative predictive value was 84%. In this study, thrombocytopenia was also an indicator of poor prognosis for patients with acute PE. CONCLUSION: The AaDO(2) measurement is a highly useful and simple measurement for predicting short-term prognosis in patients with acute PE. It has high negative predictive value and moderate positive predictive value for 30-day death and 30-day composite event. Aggressive thrombolytic treatment strategies should be considered for patients with an initial poor prognostic parameter (ie, AaDO(2) >or=53 mmHg).     

重组2型腺相关病毒-转化生长因子β3对实验性肝纤维化大鼠肝脏组织病理学和Ⅰ型胶原表达的影响

Objective To investgate the effects of TGF β 3 on rat hepatic fibrosis. Methods The TGF β 3 cDNA was cloned into rAAV2 vector. Rats were randomly divided into four groups: normal control group, model group, negative control group and TGF β 3 group. Hepatic fibrosis was induced by hypodermic injection of 40% CCI4. Recombinant AAV2-TGF β 3 viral particles were injected via the vena caudalis one week before CCh treatment. Rats were executed 8 weeks after CCI4 treatment, global histological change was observed after HE staining, the distribution of the collagen fibers was observed after masson staining, his-tochemistry was done to observe the expression of collagen Ⅰ; The positive area rate of the collagen fibers and the average optical rate of collagen Ⅰ were quantified. Results HE staining indicated that collagen fibers were reduced in the TGF β 3 group. Masson staining shown that the collagen fibers were distributed around the blood vessel, in the portal area and disse space. Compared to the model group (13.2%±2.2%) and negative control group (12.3%±1.5%), the collagen fibers in liver tissues of TGF β3 group (7.7% ± 1.5%) were significantly decreased (q = 9.456, P < 0.01; q = 8.217, P < 0.01). Histochemistry indicated that the collagen fibers of liver tissues of TGF 15 3 group (0.185±0.033) were significantly higher than those in the model group (0.252±0.042) and the negative control group (0.230±0.029), (q = 6.228, P < 0.01; q = 4.346, P < 0.01). Conclusion TGF β 3 alleviates the damage to hepatic cell and the level offibrosis in CCI4 treated rats and inhibits the expression of collagen Ⅰ.
