应用酶联免疫吸附实验测定流行性出血热早期患者尿内抗原的研究

本文首次报道应用酶联免疫吸附实验(ELISA),测定流行性出血热(EHF)患者尿中抗原,进行早期诊断,取得满意结果,本法系应用免疫的特异性和酶的高效能催化的敏感性相结合的一种方法,因而特异性强、灵敏度高。研究结果表明,7病日内阳性率较高,为93.89%;2病日内阳性率更高,为100%,故有早期诊断价值,本文用阻断实验证实尿中具有特异性抗原。此外,以正常人和其它疾病患者作对照,结果为阴性,证明本法特异性高。本法标本系用尿液,容易收集,方法简便,结果易判断,易于推广应用。     

免疫接种服务中一次性注射器处理方法及成本分析

利用山东省和陕西省现场调查资料,分析了2省不同层次医疗机构的一次性注射器的处理方式,并通过计算不同处理方式的成本,提出具有成本效果的一次性注射器的处理方式。结果表明:消毒/毁形、焚烧、掩埋和回收是主要的处理方法,在被调查的所有医疗机构中,没有一家医疗机构使用安全盒处理使用过的一次性注射器。由于没有使用规定的焚烧设备,实际调查结果表明,焚烧和掩埋的处理成本相对较低,是目前在村卫生室水平最适合的一次性注射器处理方法,而对于乡级和县级卫生机构而言,消毒/毁形和回收是目前较为适宜的处理一次性注射器的方法。     

造血干细胞移植病人出血性膀胱炎的危险因素分析

[目的]了解造血干细胞移植病人出血性膀胱炎发生的危险因素。[方法]对29例造血干细胞移植病人出血性膀胱炎的危险因素进行统计学分析。[结果]出血性膀胱炎的发生率34％(10/29例),经Logistic回归分析发现出血性膀胱炎的危险因素是预处理方案(OR值0.058 0),马利兰/环磷酰胺预处理方案出血性膀胱炎发生率高。[结论]预处理方案对出血性膀胱炎的发生有重要影响。     

宫腔声学造影在诊断及处理宫内节育器嵌顿中的价值

目的 评价宫腔声学造影（SHG）在诊断及处理宫内节育器（IUD）嵌顿中的价值。方法 应用SHG对18例疑IUD嵌顿的带器患者进行检查，并根据SHG检查结果予以相应处理。结果 SHG显示IUD浅嵌顿10例、深嵌顿4例、IUD下移1例及双器1例。除1例放弃取器外，17例病人经适当手术方法取出IUD。结论 宫腔声学造影是诊断IUD嵌顿的一种简便、有效的新方法，其结果有助于临床处理中取器方法的选择。     

云纹技术在断裂分析中的应用

改进了传统的云纹数据处理方法,提出用曲面拟合方法处理云纹数据,提高了计算机处理云纹数据的效率与质量。又提出用云纹法测量J积分的技术,可望解决实际工程构件的J积分测量问题。     

Surgical treatment of hemolytic anemia

The therapeutic effect of splenectomy in 70 cases of hemolytic anemia are reported. The diagnosis and therapeutic effects were analysed. It was evident that the effects were related to different types of hemolytic anemia. The HS type had the best result. Gallstones were detected in 6 cases of this series. Splenectomy and cholecystectomy were performed together in 5 cases. The median incision of upper abdomen was selected. The authors believe that the causes of infection after splenectomy are complicated and they cannot be explained by Igs alone.     

TD清洗消毒剂对口腔科器械消毒效果探讨

通过实验室和口腔科临床观察表明:TD清洗消毒剂(氯化磷酸三钠)对金黄色葡萄球菌、绿脓杆菌和枯草杆菌黑色变种的平均杀菌率为100.0％,对口腔科器械消毒无菌率为100％,对被HBsAg阳性血清污染的器械浸泡30分钟转阴率为98.1％。其消毒效果优于新洁尔灭,与戊二醛相同。在口腔科使用两年,未见金属器械有锈斑生成。     

ROBUST GUARANTEED COST CONTROL OF UNCERTAIN NON-LINEAR ROBOTIC SYSTEM USING MIXED MINIMUM TIME AND QUADRATIC PERFORMANCE INDEX

To provide better transient performance in controlling robots, a mixed minimum time and quadratic performance index is used. For known and uncertain revolute robot manipulators a conventional optimal control and a robust guaranteed cost control are proposed respectively. Asymptotic stability is also discussed based on the Lyapunov direct method. The proposed robust control is continuous and requires no knowledge of the uncertain system except for bounding functions.     

NGF prevents the changes induced by monocular deprivation during the critical period in rats

Photic evoked responses were recorded from the striate cortex of Long-Evans hooded intact, monocular visual deprivation (MD) and MD treated with NGF rats. The averaged visual evoked responses (AVER) were obtained from both hemispheres and provided comparison after binocular photic stimuli between the contralateral and the ipsilateral striate cortex with relation to the MD eye. One month of monocular visual deprivation at the critical period of development resulted in marked reduction of the amplitudes of AVER components as compared to the control recordings (P < 0.001). These changes of the AVER could be prevented by NGF infusion to lateral ventricle at the dosage of 2.0–2.4 μg/day for four weeks during the monocular deprivation. In conclusion, the change of AVER amplitudes induced by monocular visual deprivation during the critical period of development can be prevented by NGF infusion to lateral ventricle.
