CURATIVE EFFECT OF LICORICE ACID ZINC ON CHILDREN WITH LOW SERUM ZINC

Zinc is closely related to children's health and growth.' We selected 120 children with low serum zinc. Adopting random double-blind method, we treated two groups of children,. 60 each, with sulphate zinc syrup and licorice acid zinc capsules respectively.     

Electrodermal and microcirculatory activity in patients with fibromyalgia during baseline, acoustic stimulation and cold pressor tests.

The peripheral sympathetic activity was studied in 27 patients with fibromyalgia and 29 healthy controls through simultaneous measurements of electrodermal variables and blood flow at palmar skin sites during baseline, acoustic stimulation, and cold pressor tests. Compared to the controls, the patient group showed a significantly larger overall increase in the skin electrical conductance and less vasoconstriction during acoustic stimulation and cold pressor tests. These findings imply an increased activity of cholinergic and decreased activity of adrenergic components of the peripheral sympathetic nervous system in patients with fibromyalgia.     

API2对黏膜相关淋巴瘤凋亡及凋亡相关蛋白的影响

目的：了解黏膜相关淋巴瘤的凋亡水平及其所涉及到的信号传导通路。方法：收集33例胃肠黏膜相关淋巴样组织(MALT)淋巴瘤病例，通过TUNEL技术原位检测MALT淋巴瘤肿瘤细胞的凋亡水平，通过逆转录聚合酶链反应(RT-PCR)和免疫组织化学染色检测肿瘤的凋亡抑制蛋白2编码基因(API2)和Caspase3 mRNA及蛋白，对API2和Caspase3水平作半定量和定量分析。根据凋亡检测结果将全部病例分为两组，即凋亡细胞数每50个高倍视野小于或等于2的病例组和大于2的病例组，比较2组的API2和Caspase3 mRNA及蛋白。结果：半数以上的MALT淋巴瘤中存在凋亡抑制；凋亡抑制的MALT淋巴瘤病例中API2 mRNA及蛋白水平明显高于没有明显凋亡抑制的病例，但Caspase3 mRNA及蛋白水平在两组病例中表达没有明显的差异。结论：MALT淋巴瘤中存在明显的凋亡抑制，其发生与凋亡抑制因子API2的表达上调有关，但API2对凋亡的调节与Caspase3有关的信号传导通路无明显相关。

门诊老年冠心病患者用药知识需求的调查

冠心病是老年人的常见病、多发病,致残或死亡率已居常见病之首[1]。目前,药物治疗仍是冠心病二级预防的主要措施。近年来研究发现,83·3%的冠心病患者无法正确使用药物,用药依从性差[2]。分析原因,87%的门诊老年慢性病患者包括冠心病患者在内,主观不遵医用药是由于在用药过程中出现诸多用药问题时得不到相关知识信息支持所导致[3]。另外,通过调查证实冠心病患者对用药知识的需求亦居前列,尤其是出院后用药知识是首要需求[2,4-6]。由此表明,对门诊老年冠心病患者进行用药知识教育十分必要。依据健康教育学方法,分析患者的教育需求是制定教育…     

单核细胞流变特性异常在动脉粥样硬化进程中的作用

目的：了解单核细胞流变特性异常在动脉粥样硬化进程的作用。方法：大耳白兔６０只随机分为实验组（ＡＧ）４０只及对照组（ＣＧ）２０只，ＡＧ给予胆固醇ｌｇ．ｄ＾－１只＾－１在喟养的第２，４，８和１２周分别抽血检测单核细胞变形性，膜脂流动性及单核细胞（Ｃａ＾２＋０ｉ。结果：在兔ＡＳ阶段性进程中，单核细胞变形性，膜脂流动性下降趋势，细胞内（Ｃａ＾２＋）ｉ呈上升趋势，膜流动性与细胞内（Ｃａ＾２＋）ｉ呈负相关，变

API2-MALT1融合基因变异体在粘膜相关淋巴组织结外边缘区B细胞淋巴瘤中的分布及凋亡的关系

目的探讨API2-MALT1融合基因变异体在粘膜相关淋巴组织结外边缘区B细胞淋巴瘤(extranodal marginal zone B—cell lymphoma of mucosa—associated lymphoid tissue，MALT)中的分布特点及其转录与肿瘤凋亡的关系。方法将逆转录-聚合酶链反应和巢式聚合酶链式反应结合，检测62例不同部位MALT淋巴瘤中API2-MALT1融合基因的多种变异体；通过TdT介导脱氧核苷酸缺口末端标记技术进行肿瘤细胞的原位凋亡检测；通过逆转录-聚合酶链反应和免疫组化染色检测API2的mRNA和蛋白水平。结果62例MALT淋巴瘤中28例检出API2-MALT1融合基因(45．16％)，为变异体A1446-M1123或A1446-M814，但未检出A1446-M541和A1446-M1150。A1446-M1123(18／28)的检出明显多于A1446-M814(10／28)。融和基因转录在甲状腺MALT淋巴瘤中检出最低，在其它部位的分布无差异。在API2-MALT1^ 组(API2-MALT1mRNA表达阳性组)肿瘤凋亡水平明显高于API2-MALT1^-组(API2-MALT1mRNA表达阴性组)，API2的mRNA和蛋白水平低于阴性组。A1446-M1123^ 与A1446-M814^ 病例之间凋亡和API2的变化无差异。结论MALT淋巴瘤中t(11；18)(q21；q21)的发生有部位差异，A1446-M1123可能是中国人MALT淋巴瘤中API2-MALT1融合基因变异体的主要类型。API2-MALT1融合基因转录与MALT淋巴瘤的凋亡水平和API2的变化有关。     

体外免疫法抗MG7人源性单抗的研制及其意义

本文建立了人淋巴细胞体外致敏技术,用本文作者既往制备的鼠抗人胃癌单抗MG7作为免疫原,在体外致敏人淋巴细胞获得成功。经与本文作者在建立的人鼠种间骨髓瘤细胞系FMC-1进行人鼠人双杂交,获得一株能与鼠源性抗体反应,但不与人、羊、马、兔等其他种属动物产生的抗体相反应的人源性单抗HMG7。本文讨论了HMG7可能的应用价值,以及在人淋巴细胞体外致敏过程中应注意的几个环节。     

Screening of human anti-TNF-alpha scFv from large phage library

AIM: To clone human anti-TNF-alpha scFv from large phage antibody library. METHODS: Panning of large phage library against TNF-alpha was conducted to select specific antibodies. The antigen binding activity and DNA sequence were determined and analyzed by ELISA, restriction enzyme map. RESULTS: After 4 rounds of panning, 62 positive clones were obtained and 27 clones had specific binding ability to TNF-alpha. DNA fingerprinting of the 27 clones showed 7 different stripes indicated 7 different positive clones. 5 of the 7 clones expressed soluble anti-TNF-alpha activity. DNA sequence analysis showed that the variable regions of these scFvs belonged to different subgroups. CONCLUSION: Human TNF-alpha scFv have been successfully obtained from large phage antibody library.
