Biochemical analysis of plasma-soluble invariant chains and their complex formation with soluble HLA-DR

The invariant chain (CD74) is preferentially localized in the cytoplasm and regulates the loading of exogenous derived peptides into HLA class II heterodimers. In addition, a small proportion of CD74:class II complexes is also expressed on the cell surface. We identified and quantified soluble CD74 (sCD74) molecules in the plasma and sCD74:sHLA-DR complexes by ELISA. EDTA plasma samples from 86 healthy probands were analyzed. sCD74 could be detected in all samples with a mean concentration of 1.14 relative units±1.04 SD (range 0.17-4.31). Approximately 10% of the samples had increased amounts of sCD74 (3.0 relative units). Complexes of sCD74 and sHLA-DR were detected in all samples and their quantities were positively correlated (r=0.83, p0.001) with the sCD74 concentrations. SDS-PAGE analysis of plasma samples with high sCD74 concentrations (3.0 relative units) revealed four isoforms of sCD74 with molecular weights of 45, 43, 35, 31 kDa corresponding to known sizes of intracellular CD74. However, only molecular weights of the 45 and 43 kDa isoforms of sCD74 are found complexed with sHLA-DR. Our data demonstrate, that CD74 molecules are present in their soluble form in the plasma of healthy probands and form complexes with soluble HLA-DR molecules.     

提高H2O2/甲酸体系选择性氧化抽提脱硫效率的研究

为了降低焦化蜡油(CGO)-甲酸／H2O2选择性氧化体系中H2O2的无效分解速度，屏蔽重金属离子对H2O2分解的催化效应，考察了造纸行业中常用的硅酸钠、硅酸镁和乙二胺四乙酸(EDTA)等稳定剂和螯合剂的加入对有机溶剂抽提后CGO中含硫量的影响。实验结果表明，EDTA可以很好地和重金属离子螯合，氧化后CGO抽余油中硫含量大幅降低。     

骨盆骨折槽型固定器的研制及临床应用——附62例临床分析

为解决骨盆不稳定性骨折固定难，易产生并发症的难题，结合骨盆的特征进行研究，设计出一种新型骨盆骨折固定器，经62例骨盆不稳定性骨折的治疗观察，随访6个月～2年零6个月，治疗前后X线检查及临床疗效评定：治愈50例，好转12例，认为该固定器设计合理，操作简便，固定牢靠，有加压、撑开、纠正旋转等多项功能结合干一体，仅通过四枚4mm螺纹针，穿入髂骨的髂前上棘处，是一种治疗骨盆不稳定性骨折比较新颖和理想的外固定器。     

贲门失弛缓症的超声诊断价值

目的:探讨超声在贲门失弛缓症诊断中的应用价值。方法:对临床拟诊为贲门失弛缓症病人首先采用超声检查,诊断贲门失弛缓症38例,同时进行了X线钡剂食管及胃肠造影,并与40例正常人进行了对照。结果:超声对贲门失弛缓症的诊断符合率为100%,失弛缓症的食管管径明显大于正常对照组(P<0.01),管壁厚度亦大于正常对照组(P<0.01)食管蠕动明显减弱,甚者消失,扩张的食管腔内见有潴留的内容物。结论:超声对贲门失弛缓症诊断具有重要的临床应用价值,可取代传统的X线钡剂造影检查。     

2002～2004年市慢病院抗结核病用药情况分析

目的 掌握我院抗结核药物的用药现状及变化趋势。方法 对我院2002～2004年抗结核药物的用药品种、金额进行分析和比较。结果 我院抗结核药物的用药金额2002～2004年呈逐年上升趋势。结论 抗结核药物的品种相对较少，价格较便宜，但抗结核病药物在我院防病、治病方面占有重要的地位，其用药数量、用药金额都存不断增长，抗结核病药物品种亟待进一步开发。     

厄尔·迈纳的跨文化阐释

厄尔·迈纳的《比较诗学》从跨文化的角度对诗学作比较探讨 ,他以基础文类形成原创诗学为理论基础 ,以基础文类的分析作为跨文化阐释的切入点 ,以基础文类同异关系的把握作为诗学比较的可比性的基础 ,以一种宽容平等的对话精神作为跨文化阐释的态度 ,显示了比较诗学发展的一个必然的成熟过程。但科学的相对主义态度 ,注定了从事比较诗学面临着“诗学”“跨文化”“阐释”等因素的制约 ,这也同时为比较诗学的开拓提供了更多的空间。     

Treatment options for primary splenic low‐grade non‐Hodgkin's lymphomas

The purpose of this comparative study was to evaluate the response of primary splenic low‐grade non‐Hodgkin's lymphomas (NHL) to chemotherapy, splenectomy, and chemotherapy combined with splenectomy in order to elaborate the optimum treatment modality. A total of 104 patients (age range: 15–82 years) with primary low‐grade B‐cell NHL of the spleen were comprised by our study. Stage IV disease was determined in 102 (98.1%) cases. Regarding the treatment modality, splenectomy was performed in 14 patients, early splenectomy and single‐agent chemotherapy in 15, early splenectomy and combined chemotherapy in 19, single‐agent chemotherapy in 23, and combined chemotherapy in 33. In the above‐mentioned order, complete remission rate was following: none, 40.0, 31.6, 21.8, and 18.2%. Partial remissions were achieved in 85.7, 46.7, 57.9, 30.4, and 69.7% of cases, respectively. The median remission duration turned out to be longer (74.5 months) in the group of patients with complete remissions attained by means of splenectomy and combined chemotherapy. Local relapses in the spleen developed in 19 (72.7%) patients treated with combined chemotherapy and in 9 (90.0%), who had undergone single‐agent chemotherapy. The 5‐year overall survival was 54.4% after splenectomy, 39.4% after single‐agent chemotherapy, and 37.1% after combined chemotherapy, being significantly higher (P < 0.05) after splenectomy and single‐agent chemotherapy (67.2%), and splenectomy followed by combined chemotherapy (64.7%). Early splenectomy combined with chemotherapy is the optimum treatment option for primary low‐grade NHL of the spleen because of the superiority in complete remission rate, remission duration, and in overall survival rate. Splenectomy leads to somatic compensation of patients, makes impossible local relapsing in the spleen, prevents continuous dissemination from the primary tumor site, and mostly corrects cytopenias, creating better conditions for chemotherapy.     

东北边境地区吸血蠓的调查研究

1980～1988年在东北边境的漠河、珲春县等10个县区采获吸血蠓2属37种,其中发现4个新种和4个国内新记录。不显库蠓(35.7％)和刺螯库蠓(34.9％)为优势蠓种。不同生境、场所和季节的蠓种组成有所不同。灰黑库蠓、淡角库蠓和端斑库蠓在整个活动季节均只出现一次高峰,而不显库蠓、刺螫库蠓和兴安库蠓在整个活动季节均出现两次高峰。刺螫库蠓的活动季节最长,为11旬,端斑库蠓最短,仅为5旬。刺螫库蠓、不显库蠓、兴安库蠓和灰黑库蠓在昼夜24小时均出现晨、昏两次活动高峰,而边缘库蠓只在凌晨出现一次晨峰。
