武汉市江夏区血吸虫间接血凝试验查病质量分析

日本血吸虫病是一种严重危害我国血吸虫病疫区人民健康和影响社会经济发展的寄生虫病.血吸虫病诊断在防治工作中占有重要地位,是确定化疗目标人群的依据.目前,卫生部临床检验中心尚未建立寄生虫病血清学检测室间质评和室内质控原则和方法[1],因此,建立血清流行病学调查质量控制方法十分必要.间接血凝试验(IHA)试剂盒稳定性欠佳,各地血吸虫病查病质量难以控制,2002-2008年武汉市江夏区开展IHA查病质量控制,现将质量控制结果报告如下.

无缝钢管价格变化趋势分析

今年以来,受进口铁矿石大幅涨价、取消钢坯出口退税、3月30日国务院常务会议决定将抑制钢材有效需求增长等的影响,国内钢材市场不同品种价格出现了一定程度的波动,建筑钢材甚至出现了较大幅度下跌。今年下半年无缝钢管的价格走势如何,是我们需要重点研究和分析的课题。一、宏观政策的影响国务院常务会议强调要采取更直接、更有力的措施,应对国际铁矿石价格大幅上涨的问题;严格控制钢铁产品出口,尽快落实取消对钢坯、钢锭出口退税措施;加强铁矿石进口协调和管理,整顿和规范铁矿石经营秩序;加大钢铁行业结构调整力度,抑制钢铁生产能力盲目扩张…     

西藏气温变化趋势分析研究

本文采用线性倾向估计、M-K分析、R/S分析和小波分析等方法对西藏三地(日喀则、拉萨、泽当)近60年的气温资料进行了统计分析。全年气温变率:拉萨0.42℃/10a,日喀则0.35℃/10a,泽当0.20℃/10a。三地各季、全年平均气温变化均通过显著性检验,研究区气温在过去的50多年存在显著上升趋势。日喀则气温突变的时间为2001年,拉萨、泽当的气温变化未出现突变现象。三地未来的气温变化很可能维持现有升高趋势。三地气温变化存在较为明显的9年和25年的周期。文中对气温变化和太阳活动、CO_2浓度的关系了进行探讨。CO_2浓度持续升高和下垫面反射率(冰雪覆盖区面积减小和覆盖时间缩短)的减小,可能是当前西藏气温升高的主要原因。

Segmental splenectomy in schistosomiasis

Segmental splenectomy was performed in 5 patients with hepatosplenic schistosomiasis mansoni and symptomatic splenomegaly. The aim was to preserve a functional remnant comprising 20-30 per cent of the bulk of a greatly enlarged spleen. The operative technique involved devascularization of anatomic segments and suture of an omental patch to the residual spleen. This procedure was simple, well tolerated and effective in relieving abdominal discomfort and cytopenias. The residual spleens showed normal uptake of 99Tc-sulphur colloid. If long term observation confirms the value of segmental splenectomy in hepatosplenic schistosomiasis, it may become appropriate therapy for those patients with symptomatic splenomegaly who do not require portal decompression.     

Trend surface analysis of community variables.

Indicates that trend surface analysis is a technique used by geologists to map changes in the values and distributions of important variables across extensive topographical regions. Variations in mapped data are expressed in terms of large-scale regional trends and small-scale local deviations from those trends. Some applications of the technique to community psychology are discussed in the context of a trend surface analysis of mental disorder in a small midwestern city.

The efficacy of oxamniquine in acute schistosomiasis: a clinical analysis of 28 treated patients

During the summer of 1980, acute Manson's Schistosomiasis occurred in 28 pediatric patients, swimming in two ponds with no watershed connections between them, in the rural area of Juncos and Cidra, Puerto Rico. Clinical and immunological events were studied and Oxamniquine (Vansil, Pfizer) was administered to all of them and followed closely for 3 years. Fever and general malaise recorded in 93% of the patients, diarrhea and abdominal pain in 68% and urticaria or facial edema in 64%. Hepato and/or splenomegaly was recorded in 71% of them. Twenty seven of the patients had evidence of immunoserological activity against adult schistosomal antigens (GASP and PSAP). Two patients had intense immunologic activity, even before the recovering of fresh Schistosoma mansoni eggs in their stool. This was a response to GASP and PSAP antigens. When they started passing fresh eggs of schistosoma and COP (Circumoval Precipitation Test) turned positive, their clinical status worsened and antibodies to GASP antigen increased two fold. The oviposition phase elicited a strong antibody and immunological reaction with significant eosinophilia and cross reaction was observed between adult schistosomal and egg shell antigens. Severe clinical manifestations were seen in spite of low egg excretion. Oxamniquine was effective in obtaining a coprological cure and in altering the immunologic response as compared with other untreated groups in literature.     

Early liver dysfunction in schistosomiasis

A novel cDNA encoding a protein kinase (termed PASK) was isolated from rat brain. The PASK catalytic domain was most similar to Ste20-related protein kinases, showing 45.5 and 39.2% amino acid identity with human SOK1 and yeast Sps1, respectively. The amino-terminal noncatalytic domain of 71 amino acids was rich in alanine and proline and contained several proline-alanine repeats. PASK was widely expressed in rat tissues but negligible in liver and skeletal muscle. Immunohistochemical analysis revealed that PASK was localized to a distinct set of cells including neurons, adrenal glomerulosa cells, and transporting epithelia such as epithelial cells of brain choroid plexus, distal tubule and collecting duct of kidney, duct of salivary gland, and parietal cells of stomach. Subcellular fractionation showed that PASK was present in both the cytosol and the Triton X-100-insoluble cytoskeletal fraction in brain.     

The globule leucocyte in bovine schistosomiasis

Globule leucocytes were detected in forestomachs, abomasum, duodenum, ileum, large intestine, lung, liver, bladder and kidney in cattle infected with Schistosoma mattheei. In animals examined seven and eight weeks after infection they were found only in the lungs. They were present in the alimentary tract from 18 weeks onwards. They were most numerous and most widely distributed in animals subjected to repeated, heavy infection. There was evidence that they were associated with the immune response of the host and that they were derived from mast cells.     

Blood glucose level in hepato-intestinal schistosomiasis

Comparative oral glucose tolerance test performed in 30 patients with hepato-intestinal schistosomiasis and 30 controls, showed that the mean value of glycemia in the former group was superior. However, none of these patients show a diabetic G.T.T. curve.
