Serum concentrations of laminin and fibronectin in patients with acute coronary syndromes

Objective To study the serum iaminin (LN) and fibronectin (FN) changes in acute coronary syndromes (ACS), and explore the role of them in assessing the severity of ACS. Methods This study included 46 ACS patients [25 with acute myocardial infarction (AMI) and 21 with unstable angina (UA)], 51 stable angina (SA) patients and 47 people without CHD as controls. Serum levels of LN, FN, fibrinogen and blood fat were assessed. Coronary angiography were performed on 49 of them. Results The serum concentration of LN was lower in ACS patients [(85.20±27. 57)ng/mL], higher in SA patients [(116. 80 ± 28. 80)ng/mL] as compared to that in the control group [(100.06±29.96)ng/mL], with significant difference among the groups (P<0.05). No difference was found in FN among the three groups. However, the subgroup analysis in the group with ACS showed that the serum concentration of FN was significantly higher in UA patients [(229.60±121.39)μg/mL ], and lower in AMI patients [(108.31±47.12) μg/mL ]. The serum LN and FN concentration could respectively enter the logistic regression equations of ACS patients and US patients. Neither LN nor FN concentration was correlated with narrowing of coronary artery of angiography. Conclusion Serum LN and FN level may be a useful indicator for stability of atherosclerosis plaque in coronary arterial disease patients, but could not predict the extent of narrowing in coronary angiography.     

维甲酸胶囊的制备及临床应用

研究了治疗骨髓增生异常综合症（ＭＤＳ）的药物维甲酸胶囊的处方、生产工艺及质量标准。应用维甲酸胶囊治疗４例骨髓增生异常综合症，剂量为６０～１２０ｍｇ／ｄ不等，１例２３ｄ共服用２７６０ｍｇ，全部获得好转。４例患者在用药期间均未出现肝功能损害。     

病态建筑综合症影响因素的模糊灰关联分析

病态建筑综合症已成为我们面临的最普遍的室内卫生难题之一.针对室内空气污染物与病态建筑综合症之间的定量研究较少,文中运用模糊灰关联分析法,计算了室内污染水平与病态建筑综合症之间的模糊灰关联度,研究分析了室内空气污染物与病态建筑综合症的定量关系.结果表明:室内空气污染物中,甲醛与吸入尘对病态建筑综合症的影响程度最大,这为建筑室内环境系统的设计和维护提供了关注的重点和依据.     

Apoptosis of lumbar spinal cord neurons in cauda equina syndrome rats

Objective To explore the law of apoptosis of lumbar spinal cord neurons in cauda equina syndrome (CES). Methods Cauda equina of rats was compressed by a piece of silica gel stick. From day 1 to day 28, the lumbar spinal cord specimens were harvested and assessed by Nissl's staining and TUNEL staining. Results Compression of cauda equina caused lesion and apoptosis of neurons in lumbar spinal cord, and the extent of apoptosis reached the peak on 7th day after compression. Conclusion Apoptosis of neurons in lumbar spinal cord might be one of the reasons why patients with CES get poor prognosis.     

多囊卵巢综合征的生殖内分泌特征、卵巢形态学改变与克罗米酚疗效间的关系

目的　探讨多囊卵巢综合征 (PCOS)妇女用克罗米酚 (CC)促排卵治疗无效的原因 ,以预测其疗效。方法　 41例PCOS患者均计算BMI ,行F G毛发评分 ,服CC前后测血清生殖激素水平 ,B超了解卵巢形态并监测排卵。结果　与CC治疗有反应组相比 ,无反应组的F G毛发评分、基础A、fT增高 ,卵泡数增多 ,卵巢体积及髓质面积增大 ,卵泡晚期FSH、LH、E2 降低 (P均 <0 0 5) ;相关回归显示平均卵泡数与T、A ,平均髓质面积与A呈正相关。结论　多毛患者对CC治疗的反应性降低。H P O轴功能状态可影响CC疗效 ;一定的激素水平和卵巢超声表现提示CC抵抗 ;卵巢超声形态与T、A间存在正相关     

淋病后综合征的病因学分析

目的 为了进一步探讨“淋病后综合征”的病因及与性病恐怖症之间的关系。方法 对80例单纯性淋病正规治疗后淋球菌转阴情况下仍有临床症状的患者进行衣原体、解脲支原体、滴虫、念珠菌的检测及其病因、症状的调查分析。结果及结论 淋病后综合征患者中除少数伴有其它病原体感染外,大多数是性病疑病症的一种表现。     

血清nCa2+含量在肾综合征出血热中的动态变化

目的 研究血清离子钙(nCa２＋)在肾综合征出血热(HFRS)中的变化规律及在发病中的作用。方法 用离子选择电极法检测了46例HFRS患者不同病期血清nCa２＋含量,并将nCa２＋与血清尿素氮(BUN)、肌酐(Cr)做相关分析。结果 HFRS患者在低血压休克期和多尿期时血清nCa2＋含量降低(P＜0..05),以少尿期最为显著(P＜0..01)。而且随病情加重,结果依次降低,危重型患者整个多尿期也明显降低。血清nCa２＋含量与BUN、Cr呈负相关(P＜0.01)。结论 血清nCa２＋参与发病过程,与病情轻重和肾功状态密切相关。     

特发性QT间期延长综合征1例家谱调查

观察了1例特发性QT延长综合征的家族，家族中11人有5例QT校正值延长。本文资料提示其发病机理可能与交感平衡及复极内在异常有关。用β-受体阻滞剂治疗效果较好。     

家族性病态窦房结综合征(附1例系谱调查报告)

本文观察了一个病态窦房结综合征(简称SSS)伴常染色体显性遗传的家族。家族24人中有SSS4例。文献报道家族性SSS 的病因及发病机理不清,诊断标准为同一家族中发现多例SSS 患者,有明显的先天性和家族性倾向。治疗及预后同一般SSS。而本文资料表明,家族性SSS 的病因及发病机理与迷走神经张力持续升高有关,并有较好的预后,晚期多转变为持续且心室率较缓慢的心房扑动或心房颤动,一般不需安置人工心脏起搏器。
