Objective To determine the early diagnostic value of serum C -reactive protein (CRP)、 total complement( CH50 ) activity and complement 3 (C3) concentration of premature women in the subclinical infection.MethodsSolid phase enzyme linked immunosorbent assay ( ELISA method ) was used for measurements of serum CRP levels. According to modified Mayer simple tubular colorimetric method and simple agar immunodiffusion method, we determined the CH50、C3 concentration respectively.Results Premature women with subclinical chorioamnionitis showed higher serum CRP concentration than that of normal pregnancy women (P<0.01). In the subclinical chorioamnionitis, the more serious the infection, the higher the CRP concentration, while CH50 and C3 concentrations were correspondently decreased. Serum CRP concentration in premature labor was the most sensitive index that suggested subclinical chorioamnionitis. ConclusionsSerum CRP、CH50 and C3 concentrations in premature labor are simple,reliable and accurate indexes for early diagnosis of subclinical infection.

Background and purpose:Suppression of apoptotic signaling pathways is an important factor in tumor cell resistance. Research on cell apoptosis will open up a new way of reversing drug resistance and tumor treatment. This study examined the effects of a novel naphthalimide derivative 8c on multidrug resistant colon cancer HCT116/L-OHP cells and explored the molecular mechanisms underlying the apoptosis induction. Methods: The anti-proliferative effects of 8c were detected by CCK-8 assays and the effects on apoptosis induction were examined by lfow cytometry. The mRNA expression levels of p53, Bax and Bcl-2 were measured by real-time PCR;The protein expressions of p-p53, Bax, Bcl-2 and Cyt-c were detected by Western blot. Results:8c (IC50=8.16 μmol/L) seemed to be more potent than amonaifde (IC50=28.37 μmol/L) against HCT116/L-OHP cells. 8c induced apoptosis on HCT116/L-OHP cell lines through intrinsic or mitochondria dependent pathway. The protein expression of phosphorylation of p53 at Ser-15 was increased, but the mRNA level of p53 did not increase in HCT116/L-OHP cells. Bax protein and mRNA levels were signiifcantly increased, and Bcl-2 protein and mRNA levels were decreased, suggesting an increase of Bax/Bcl-2 ratios. Meanwhile, 8c induced a substantial release of cytochrome c from the mitochondria into the cytosol in HCT116/L-OHP cells. Conclusion: 8c induced cell death signal by inducing the activation p53 phosphorylation which subsequently activated related protein expressions of apoptotic pathway, which may be an important mechanism of 8c on inhibiting proliferation of HCT116/L-OHP resistant cells. All the results suggested that 8c was a potent compound to be developed as an anti-tumor and anti-resistance agent for clinic application in the future.
