ABSTRACT
Objective To investigate the pathogenesis of interleukin-21 (IL-21)role in primary biliary cirrhosis (PBC).Meth-ods 38 cases of PBC were selected for the study.35 caeses of healthy subjects were selected as the control group in January 2012 to January 2014 from Shenzhen Fuyong People’s Hospital of Baoan District and the Third People’s Hospital of Shenz-hen.The levels of IL-21,IL-17 of two groups were measured with Enzyme-linked immunosorbent assay (ELISA).The levels of T helper lymphocytes 17 (Th17),regulatory T cells (Treg)cells ratios of two groups were measured with flow cytome-try.The relationship of IL-2 1 and liver function were analyzed with pearson correlation.Another analysis of pyruvate through the establishment of in vitro deaminase complex E2 subunit (PDC-E2)peptides relationship with Th17 and Treg cell.Results The levles of IL-17 (18.23±4.12)ng/L,IL-21 (512.25±18.25)ng/L,Th17 (3.98±0.98)%,Th17/Treg (39.25±3.25)% of PBC group were significantly higher than the control group (7.89±3.26)ng/L,(212.98±21.52)ng/L,(0.92±0.21)% and (12.98±3.12)%,while the PBC group Treg (3.11±0.85)% were lower than the control group (8.36±1.12)%.IL-21 were positive correlation with IL-17,Th17 (t=8.886,7.021,4.448,10.112,5.125,P<0.05).In vitro experiments showed that the addition of IL-21 in the culture system,the levels of Th17 (2.41±0.82)%,Th17/Treg cells(32.98±3.12)% were significantly higher than the control group(0.98±0.21)%,(12.25±3.25)%,while Treg (4.75 ±0.68)% were lower than the control group(11.85±0.96)%,the difference was statistically significant (8.521,6.489, 8.236,P<0.05).Conclusion IL-21 levels increased with the pathogenesis of PBC has a close relationship,which can pro-mote the reaction of PDC-E2 Th1 7/Treg immune imbalance caused thereby occurs mediated by PBC.
ABSTRACT
ObjectiveTo study the heat shock protein 47 ( HSP 47 ) andtype Ⅰ ,Ⅲ collagen relevance expression in keloid tissue. MethodsUSE immunohistochemistry to detect 21 patients( HS group) pathological keloid tissue HSP47, Ⅰ-type, Ⅲ collagen levels,and normal foreskin(control group) compared to the expression of HSP 47 and Ⅰ and Ⅲ collagen. ResultsHS group HSP 47 scar absorbance was( A value) ( 133.0 ± 58.7) ,it was significantly lower than the control group( 169.6 ± 53.2) ( t =2. 697 ,P =0.024) ;two groups of collagen type Ⅰ, Ⅲ collagen levels had statistically differentce(t =14.898,12.610,all P =0.000) ; HSP 47 level and type Ⅰ collagen were positively correlated(r =3.058,P =0. 034),and type Ⅲ collagen content was also positively correlated(r =4. 610, P =0. 029). ConclusionHSP 47 in keloid tissue could cause dermal layer assembly of collagen synthesis and significantly increased,and it was an important mechanism for the formation of keloids.
