Objective To assess the effects of tibolone treatment on the hemodynamic changes of the ophthalmic artery(OA) and internal carotid artery(ICA) as sonographic markers of atherosclerosis in menopausal women.Methods A total of 30 menopausal women were treated with 2.5mg of tibolone(Livial) daily as treatment group.At the same time,30 women with natural menopause who were not given any treatment served as control group.Noninvasive measurements of the resistance index(RI) and peak systolic blood flow velocity of ICA and OA were made with ultrasound before the treatment and at 3rd,6th,9th and 12th month of treatment,respectively.Results RI of ICA and OA decreased significantly after tibolone treatment(P

Objective To observe the effects of hormone replacement therapy (HRT) on endothelial function in menopausal women. Methods A total of 30 menopausal women were treated with 2.5 mg of Tibolone (Livial) daily. At the same time, 30 women with natural menopause without any treatment served as the control group. Endothelium-dependent (EDD), endothelium-independent (NID) vasodilatation function, and estradiol (E2) were examined by the non-invasive high-resolution ultrasonography before the treatment and at 12th, 24th, 36th and 48th week of treatment, respectively. Results After hormone treatment, E2 increased significantly and EDD was improved significantly (P<0.05), and E2 was positively related with EDD (r=0.8092, P<0.001). No change of EDD was observed in the control group whereas a significant increase was observed in the treatment group. Conclusion Endothelium-dependent vasodilatation dysfunction is prominent in menopausal women. Tibolone can help improve the condition.

Objective To study the relationship between PDD and the polymorphism of apolipoprotein E(apoE) gene,to inquire the etiological basis of PDD.Methods 11 Patients with PDD 40 patients with PD without dementtia and 52 unrelated controls were collected to detect the genotype of apoE gene by PCR－ RFLP. Results There was no difference in the apoE allele frequencies and genotype distribution in PDD group,PD without dementia group and control group(P >0.05). Conclusion There is no relationship between the polymorphism of apoEgene and the onset of PDD.The pathogenesis of PDD differs from that of AD.

Asthma is a common disease in children. Adherence to inhaled glucocorticoid therapy directly affects the outcome of asthma. The article mainly reviews the adherence status, assessment method, patient barriers to non-adherence and intervention strategy,so as to provide references for clinical practices and scientific research of nursing staff.

Objective:Based on relevant database data analysis,to explore the correlation of the abnormal expression of EMT related factors and chronic obstructive pulmonary disease and its related non-small cell lung cancer.Methods: Based on some data sets of GEO in the NCBI database,to perform express analysis,survival analysis and correlation analysis.Results: ①Snai1 and other EMT related regulatory factors exist significantly higher expression in non-small cell lung cancer patients,and E-cadherin (CDH1) was showed significantly lower expression. ②A large number of COPD patients samples were analyzed,and some EMT-related molecules in patients with COPD also showed significant abnormal expression and consistented with the changes in patients with non-small cell lung cancer.Conclusion: The results showed that dysregulation expression of EMT related regulatory factors may have some correlation with disease progression of COPD patients through the EMT markers and their expression and correlation analysis in COPD patients.

Objective To explore the relationship between bronchial asthma severity and the levels of nerve growth factor(NGF) in induced sputum.Methods One hundred and seventy children with asthma were divided into two groups, including 87 cases of chronic duration group and 83 cases of acute phase group.Before treatment lung function test was conducted, induced sputum was taken immediaitely, the levels of NGF were measured by enzyme-linked immunosorbent assay and Eosinophils (EOS)in induced sputum were count.Comparative analysis was conducted.Results The levels of NGF,FEV1 ,FVC,PEF and EOS in duration group were significantly elevated compared with acute phase group (all P ＜ 0.05).Significant differences in NGF, FEV1, FVC, PEF and Eos were found by comparison of different extent in chronic duration group and acute phase group (all P ＜ 0.05), the levels of NGF were positive correlated with illness severity (all P ＜ 0.05) in children with afsthma in chronic duration and acute phase, the levels of NGF were positive correlation with FEV1, FVC, PE-Fand EOS (all P ＜ 0.05) in children with asthma in chronic duration, the levels of NGF were positive correlation with FEV1 and PEF in children with Asthma in acute phase,but the levels of NGF has no correlation with FVC and EOS (all P ＞ 0.05) in children with Asthma in acute phase.Conclusion The levels of NGF in induced sputum of children with asthma in acute phase are markedly elevated compared with children with asthma in chronic duration, the levels of NGF are positive correlated with illness severity in children with asthma in chronic duration and acute phase.

[ ABSTRACT] Tyrosine kinase inhibitors ( TKIs) are now advocated as the first-line treatment for chronic myeloid leukemia ( CML) , but facing resistance and relapse .Leukemia stem cells ( LSCs ) are leukemia-initiating cells as the source of resistance and relapse .It is therefore important to discover the molecular biomarker of LSCs for developing anti -LSC strategies in leukemic therapy .15-Lipoxygenase (15-LO) is a key enzyme in the pathway of arachidonic acid and plays an important role in the occurrence and development of CML , which is specifically required for chronic myeloid LSCs . This review summarizes the influence of 15-LO on the chronic myeloid LSC characteristics of marked survival , self-renewal, proliferation , differentiation and apoptosis .

Objective To investigate the effect of S-1 on serum thymidine kinase-1 ( TK1 ) , vascular endothelial growth factor ( VEGF ) and insulin-like growth factor-1 (IGF-1) and tumor biomarkers, estrgen levels and quality of life in patients with advanced breast cancer.Methods 69 cases with advanced breast cancer from January 2014 to May 2015 in the hospital were selected and randomly divided into two groups.34 cases in control group were treated by conventional therapy, and 34 cases in experimental group were treated with S-1.Serum TK1, VEGF and IGF-1, tumor biomarkers, estrogen level and quality of life score were compared pre-and post-treatment.ResuIts Compared with control group, the levels of VEGF, IGF-1 and TK1 were lower (P<0.05), serum CA125, CEA and CA15-3 concentrations were lower (P<0.05),the LH, E2 and E1 levels were lower (P<0.05) and the survival quality score was higher in experimental group ( P<0.05 ) .ConcIusion S-1 has better clinical curative effect in treatment of patients with advanced breast cancer, and effectively reduce serum TK1, VEGF, IGF-1, tumor biomarker levels, improve the quality of survival, which has important significance.
