Objective To study the clinical significance of estradiol(E2)and low-density lipoprotein cholesterol(LDL-C)in postmenopausal atherosclerotic ischemic stroke(IS).Methods A total of 110 postmenopausal patients with atherosclerotic IS who were treated in the First People's Hospital of Huzhou from March 2022 to March 2023 were included in study group,110 postmenopausal patients with non-atherosclerotic IS were included in disease control group,and 110 healthy postmenopausal women were included in health group.The serum E2 and LDL-C were compared among all groups.The relationship between serum E2 and LDL-C levels and the degree of disease in postmenopausal patients with atherosclerotic IS was analyzed.To explore the risk factors that influence the degree of disease in postmenopausal patients with atherosclerotic IS.Results There were significant differences in serum E2 and LDL-C levels among three groups(P<0.05),including E2 level in healthy group>disease control group>study group,and LDL-C level in healthy group

Objective To detect specific polymorphisms in Toll-interleukin 1 receptor domain containing adaptor protein(TIRAP) coding region for Chinese Han population, and verify whether they are associated with susceptibility to tuberculosis. Methods Search TIRAP polymorphisms by sequencing in small sample; detect single nucleotide polymorphism(SNP) by ligase detection reaction technique in large sample; analyze whether polymorphisms are related to tuberculosis by statistic methods. Results Four polymorphisms were present in the TIRAP coding region. 394A had higher frequencies in the tuberculosis(TB)group than the control. But allelic and genotypic analysis showed that there were no significant difference in statistic between TB patients and controls(P>0.05). The SNP G164A mutation related with TB patient's condition. Comparing to controls, retreatment patients' allelic frequencies had significant difference in statistic(P<0.05), sputum positive patients and lung cavitation patients had lower 164A frequencies. Conclusion TIRAP coding region polymorphisms may be risk factors for TB occurrence and development in Chinese Han population.
