ABSTRACT
Objective To investigate the relationship of HSP27 expression with treatment response ,remission rate ,prognosis in multiple myeloma(MM) patients .Methods Eighty‐six patients with MM first diagnosis and 27 relapse cases were collected re‐spectively .Control was defined as non‐hematological malignance .The MM patients divided into first diagnosis ,relapse conventional chemotherapy group and bortezomib group .HSP27 expression and protein level were measured on pre‐and post 1 ,2 and 3 treatment circles .Results The tendency of HSP expression and protein level:relapse‐MM patients> first‐diagnosis MM patients> control . HSP27 expression and level in Ⅲ phase was higher than those in Ⅱ phase for first‐diagnosis MM patients .Bortizomib‐containing chemotherapy protocol showed more effectively decrease on HSP27 than chemotherapy treatment only .At post‐1 treatment circle , HSP271 and delayed the relapse time .Conclusion BMMNC‐HSP27 expression and protein level is associated with staging ,treatment response and prognosis in MM patients .
ABSTRACT
Objective To seek the specific receptors associated with hepatitis B virus (HBV) adhesion by separating the binding protein of the HBV preS1 region in HepG2 and performing the mass spectrometry .Methods The immunomagnetic bead method was adopted to separate HepG2 membrane protein combined with preS1 peptide fragment and the binding protein was separated by the sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) ,then the destination strips was analyzed by LC-MS/MS mass spectrometry and retrieved by the database .Results 16 bands were separated from HepG2 membrane proteins combined with preS1 by SDS-PAGE ;14 kinds of proteins were identified from 6 bands with better repeatability separated from HepG 2 membrane proteins combined with preS1 .Conclusion Protein analyzed by the mass spectrometry is mainly related with the material transport , cellular signal transduction ,antigen presentation ,immune regulation and energy metabolism .
ABSTRACT
Objective To explore the climacteric women's mental health status and its influencing factors,and cognition of relevant knowledge about climacteric period.Methods A stratified-cluster sampling method was used to survey with questionnaire 2 500 perimenopausal women aged 40-60 years in 6 districts of Xi'an City.Results ① Of a total of 2 023 individuals,the mean age was 47.38?5.429 years,the average menarche age was 14.31?1.74 years(9-19 years),and the average natural menopause age was 48.9?3.54 years.② Half of the women investigated were worried about their children's education,work,marriage,ecomomic status and housing,and more than half of the women investigated had insufficient knowledge about climacteric period.③ The incidence of climacteric syndromes was 54.9%.There were significant differences between different age group and occupation group(?2=226.14,P
