陕南安康地区大竹园镇砷中毒患者血清PICP、PINP与COL1α1序列检测

目的 研究陕南安康地区大竹园镇高砷高氟高硒地区的砷皮肤损伤患者体内Ⅰ型胶原代谢状况.方法 采用病例对照研究,选取安康大竹园镇燃高砷高氟高硒石煤区29例砷皮肤损伤患者为病例组,西安市非砷中毒区30例为对照组.用石墨炉原子吸收光谱法测定砷和硒含量.氟离子选择性电极法测定氟含量,ELISA检测血清中Ⅰ型前胶原羧基前肽(PICP)和Ⅰ型前胶原氨基前肽(PINP)的含量,高保真PCR扩增-美国ABI3100测序仪作正反向直接测序检测Ⅰ型胶原α1多肽链(COL1α1)碱基突变.结果 在偏相关分析中控制其他影响因素后,PICP与血清氟呈弱负相关r=-0.4,P≤0.05),PINP与发氟呈中度负相关(r=-0.5,P<0.05),与发硒呈中度正相关(r=0.5,P<0.05).但血清PICP、PINP与COL1α1序列在病例组和对照组间无统计学显著性差异(P>0.05).结论 发氟和发硒是影响PINP代谢的主要影响因素,且发氟升高可使PINP降低而发硒升高町使PINP增高.但在陕南安康地区大竹园镇砷、氟和硒三元素联合性增高地区的砷皮肤损伤患者体内的PICP、PINP含量和Ⅰ型胶原α1基因序列却无显著性改变.提示在该地区,发硒增高引起PINP的升高可能抑制了由发氟升高引起PINP的降低.

Relationship between SP1 polymorphism and osteoporosis in β-thalassemia major patients

Background: β-Thalassemia is an autosomal recessive disease characterized by defective β-globin chain production. Osteoporosis is an important cause of morbidity in patients with β-thalassemia major. The pathogenesis of reduced bone mineral density (BMD) is multifactorial. A range of genetics factors have been implicated in other populations of patients with osteoporosis. Polymorphism at the Sp1 binding site of the collagen type I A1 ( COLIA1 ) gene is thought to be an important factor in the development of osteoporosis.
Methods: Alleles S and s , detected by presence of a G or T nucleotide, respectively in a regulatory site of the COLIA1 gene were investigated in 37 β-thalassemia major patients with osteoporosis and 92 controls without osteoporosis or osteopenia using polymerase chain reaction–restriction fragment length polymorphism.
Results: Fifteen and nine β-thalassemia major patients displayed SS and Ss genotypes, respectively, whereas 13 were found to have an ss genotype. The mean BMD of the β-thalassemia major patients with ss genotype was similar to those with the Ss and SS genotypes. In the control group, 77 and 15 subjects had SS and Ss genotypes, respectively, with no ss genotype. Allelic and genotypic distribution in patients were significantly different from controls.
Conclusion: Determining base substitutions at the Sp1 binding site on the COLIA1 gene in early years may be important in preventing osteoporosis in children with β-thalassemia major.     

单胺类递质在大鼠癫痫发作心脏损伤中的作用

目的:观察癫痫发作前、发作时及发作后血浆去甲肾上腺素(NE)及血清心肌肌钙蛋白I(cTnI)含量以及心脏病理变化。探讨癫痫发作致心脏损害的发生、发展机制。方法:健康Wistar大鼠40只随机分成癫痫组(EP)和对照组(Control)。癫痫由青霉素诱导发作,动态监测大鼠癫痫发作时和发作后不同时间点血浆NE含量及血清cTnI水平的变化。NE的测定采用高效液相-电化学法,cTnI的测定采用光化学发光法。结果:大鼠癫痫发作时血浆NE明显升高,NE升高持续约1h以上。癫痫发作后1h血清cTnI水平开始升高,12h达高峰,随后逐渐下降。心脏病理检查证实癫痫发作可引起心脏损害。结论:癫痫发作时NE含量升高在癫痫发作致心脏损害过程中起重要作用。

The Induction of Cytotoxic T Lymphocytes against HLA-A Locus-matched Lung Adenocarcinoma in Patients with Non-small Cell Lung Cancer

To induce cytotoxic T lymphocytes (CTL) against non-small cell lung cancer (NSCLC) efficiently, the induction of CTL was attempted using HLA-A locus-shared allogeneic NSCLC cells. T cells derived from either tumor tissue specimens or the regional lymph nodes of patients with NSCLC were stimulated twice or three times with an HLA-A2/A24-positive NSCLC cell line (PC-9), and thereafter the cytotoxic activity was examined by ⁵¹Cr-release assay. In patients with HLA-A24/ adenocarcinoma, anti-PC-9 cytotoxicity was induced in all 6 patients tested. Anti-PC-9 cytotoxicity was induced in 2 out of 5 patients with HLA-A2 (A24⁻)/adenocarcinoma, in 2 out of 4 patients with HLA-A24/squamous cell carcinoma, and 1 of 2 patients with HLA-A2/squamous cell carcinoma. The cytotoxic activity was observed to kill PC-9 selectively, not other NSCLC lines, and the activity was substantially blocked by anti-MHC class I antibody, but not by anti-MHC class II antibody. The PC-9-specific CTL produced γ-interferon in response to autologous tumor cells. These results indicated that the anti-PC-9 cytotoxicity was mediated by cytotoxic T lymphocytes that may recognize the T cell epitope(s) shared and presented by HLA-A2 and/or HLA-A24-positive NSCLC.
