The RA5-01 rheoanalyzer

The diagnostic potentialities and technical characteristics of the first series-produced automated device for recording and processing of the rheocardio-, rheovaso- and rheoencephalosignals are described. The device is fitted out with a three-channel rheotransducer, a microprocessor analyzer equipped with a representation unit and a recorder for tracing the processed data on electrographic paper. Five diagnostic techniques are reviewed. They are employed in the device for studying the central hemodynamics and the hemodynamics of the limbs and head.     

Clinical and epidemiological evaluation of a live, cold-adapted influenza vaccine for 3-14-year-olds.

Reported is a study of live, cold-adapted (CA) reassortant mono-, di-, and trivalent influenza type A and B vaccines in a series of controlled clinical and epidemiological investigations involving nearly 130 000 children aged 3-15 years. The results of clinical, immunological, and morbidity investigations of the vaccinees and a control group over 6-months'' follow-up indicated that the vaccines were completely attenuated by the children. Transient febrile reactions occurred in < 1% of the children after vaccination, including double seronegative individuals with low antibody titres. The type A reisolates examined were genetically stable. The reassortants did not suppress each other after simultaneous inoculation of children and stimulated antibody response to influenza virus strains A1, A3, and B. The incidence of influenza-like diseases was approximately 30-40% lower among the vaccinated group than among the control group. The study demonstrates, for the first time, the efficacy of CA vaccine against infections caused by influenza B virus.     

Influenza activity--United States, 2000-01 season

This report summarizes influenza activity in the United States during October 1-November 25, 2000 (1). Influenza activity was low during this period, and influenza virus isolates were reported from 11 states. The viruses most frequently isolated were influenza A (H1N1) and were well matched by the 2000-01 influenza vaccine strain.

OS-250-01 illumination for endoscopic apparatus

The paper gives information on the new illuminator for endoscopic apparatuses, which provides higher light optic and electric characteristics than do its existing analogues. It also presents the specific features of the illuminator and compares the technical data of the new illuminator and its analogues.     

Influenza activity--United States, 2000-01 season

This report summarizes influenza activity in the United States during November 26, 2000-January 13, 2001. Influenza activity was low to moderate but increasing in the United States. Since October 1, the most frequently isolated viruses were influenza A (H1N1) and were well matched antigenically with the 2000-01 influenza A (H1N1) vaccine strain.     

Clinical algorithm for cerebrospinal fluid test of 14-3-3 protein in diagnosis of Creutzfeldt-Jacob disease

OBJECTIVE: To study whether an algorithm that includes additional diagnostic information could increase the specificity of the 14-3-3 protein testing in patients suspected to suffer from Creutzfeldt-Jakob disease (CJD). DESIGN: The development of a diagnostic algorithm. METHOD: The 14-3-3 protein was tested in the cerebrospinal fluid from 69 consecutive patients suspected of having CJD. On the basis of a former study and literature research, a diagnostic algorithm was constructed, which restricted the indication for performing the 14-3-3 protein test. RESULTS: By taking into consideration the findings of neuroimaging and routine cerebrospinal fluid examination prior to 14-3-3 testing, the specificity increased to 97% (95%-CI: 85.5-99.9) thus changing the prior probability of having CJD of 35% to a posterior probability of 75-100%, in the case of a positive test result. CONCLUSION: Determining the presence of 14-3-3 protein is a highly sensitive and specific marker for sporadic CJD when used in combination with imaging and cerebrospinal fluid examination.     

卵巢子宫内膜异位囊肿患者血清CA 125及临床相关因素分析

目的:探讨CA125在子宫内膜异位症的诊断意义及影响CA125水平可能存在的临床相关因素。方法:回顾性分析卵巢内异囊肿组76例,卵巢囊肿组58例及子宫腺肌症组32例血清CA125值及相关临床因素。结果:异位囊肿组CA125值(34.1±5.4)IU/ml,腺肌症组血清CA125值(30.7±4.3)IU/ml,均显著高于卵巢囊肿组。血清CA125诊断卵巢巧克力囊肿的敏感性为28.95%,特异性为92.63%。内异患者血清CA125水平随着rAFS分期期别的升高而增加。内异囊肿合并有盆腔粘连患者血清CA125值显著高于无粘连患者(P<0.05),且CA125值与rAFS分期粘连评分分值呈正相关,r=0.253,P<0.05。rAFS分期中,各个期别的痛经以及不孕的发生率没有显著差异(P>0.05)。血清CA125值与月经周期无明显相关性。不同生育和流产次数患者之间以及内异囊肿左侧、右侧或者双侧各组之间CA125水平差异无显著性(P>0.05)。结论:血清CA125在异位症患者中明显升高,尤其是重度者,可作为与卵巢囊肿鉴别诊断的辅助指标,CA125可作为术前评价内异症盆腔粘连严重程度的一个指标。
