Metabolomic mechanism and pharmacodynamic material basis of Buxue Yimu pills in the treatment of anaemia in women of reproductive age.

Objective: To explore the pharmacological basis and mechanism of Buxue Yimu pills (BYP) in the treatment of anaemia in women from the perspective of metabolomics and network analysis. Materials and Methods: Forty-six women of reproductive age with haemoglobin 70-110 g/L were recruited. Blood samples were collected before and after 4 weeks of oral BYP treatment to assess the changes in haemoglobin, coagulation function, and iron metabolism indices. An integrated analysis of metabolomics (liquid chromatography mass spectrometry) and network analysis was performed to identify the potential pharmacodynamic mechanisms of BYP. Results: After BYP treatment, the haemoglobin level of patients significantly increased from 93.67 ± 9.77 g/L to 109.28 ± 12.62 g/L (p < 0.01), while no significant changes were found in iron metabolism and coagulation-related indicators. A total of 22 differential metabolites were identified after metabolomics analysis, which were mainly related to the inhibition of inflammation and oxidative stress. Integrating pharmacodynamics and metabolomics, a network of drug-active components-targets-metabolic pathways-metabolomics was established. Acetylcholinesterase, phospholipase A2 group IIA, and phospholipase A2 group IVA may be the most promising therapeutic targets. Conclusion: BYP can inhibit inflammation and oxidative stress as well as promote haematopoiesis, potentially improving anaemia.

Caveolin-1, EGFR expression in bladder transitional cell carcinoma and their prognostic value / 肿瘤研究与临床

Objective To study Caveolin-1,EGFR expression in bladder transitional call carcinoma and their prognostic value. Methods Immunohistochemical method was used to detect Caveolin-1,EGFR in 89 cases.of bladder transitional call carcinoma.Results In 89 cases,the percentage of abnormal Caveolin-1 and EGFR expression were 37.1% and 50.6 % respectively.Significant change was observed in different grade case,P

Study on the correlation between acute lymphoblastic leukemia and HLA genes in southern China Han population / 中国实验血液学杂志

To study the correlation between acute lymphoblastic leukemia (ALL) and HLA-A, B and DRB1 gene in southern Chinese Han population and to investigate the susceptible HLA gene to ALL, a total of 4707 healthy volunteer bone marrow donors from southern Chinese Han population were used as a control group, 201 patients diagnosed as patient group from southern Han individuals were genotyped at HLA-A, B and DRB1 loci by PCR-SSP, PCR-SSOP and SBT. HLA allele frequency and its distribution of ALL patient group were compared with the control group by using chi(2) test, and calculated the statistic value of relative risk (RR), pathogenicity score (EF) and preventive score (PF). The results showed that in comparison with the control group, the gene frequence of HLA-A26, B56 and DR9 increased significantly, but the gene frequence of HLA-A30, A33 and B58 allele frequency decreased significantly for patients with ALL. It is concluded that HLA-A26, B56 and DR9 gene have a high correlation with ALL and seem to contribute the genetic susceptibility to ALL in southern Chinese Han populations. However, HLA-A30, A33 and B58 gene seem to have protective role for southern Han individuals suffered from ALL.

Significance of examine of??T and NKT cells in non-small-cell lung cancer / 肿瘤研究与临床

Objective To open out new method,we probe into immune function of??ST and NKT cells in NSCLC.Methods The peripheral blood cells were stained with antibodies labeled with fluorescence in NSCLC,??T,NKT and their set group cells were counted with flow cytometry.Results The absolute counts of??T,CD~+_(56)??T,CD~-_(56)??T,NKT and??T~+ NKT cells in NSCLC was significantly lower than that of normal controls.The relative counts of NKT,??T~+ NKT,??T~-NKT and CD~+_56??T cells in NSCLC was not sig- nificantly lower than that of normal control.The absolute counts of??T cells in NSCLC positively correlated to the number of NKT cells,(r=0.426,P=0.009).Conclusion The absolute counts of??T,NKT and their set ground cells in NSCLC was significantly lower than that of normal controls.In NSCLC the relation of the??T and NKT had positive correlation.
