Objective To evaluate the clinical application value of flow fluorescence assay in determination of serum pepsinogenⅠ and Ⅱ.Methods The precision of flow fluorescence assay in the detection of serum pepsinogen Ⅰ and Ⅱ were evaluated. Methodology comparison were conducted between flow fluorescence assay and enzyme-linked immunosorbent assay(ELISA)kit through detecting clinical samples.The reference ranges for PGⅠ and PGⅡ/PGⅠ ratio of healthy population were established. The levels of PGⅠand PGⅡ/PGⅠ ratio were detected in serum samples of patients suffering superficial gastritis,atrophic gastritis and gastric cancer.Results The within-run and between-run coefficient of variation of PGⅠ were 4.26%-5.35% and 6.73%-7.75%,respectively.And those of PGⅡ were 5.48% - 6.42% and 8.46% -8.85%,respectively.Methodology comparison be-tween flow fluorescence assay and ELISA demonstrated good linear correlations.The linear equation wasY =0.91 1X -22.635(r=0.966,P <0.05)and Y =0.892X -0.548(r=0.980,P <0.05)for PGⅠ and PGⅡ,respectively.The lower limit of the reference range of PGⅠ and PGⅡ/PGⅠ ratio were 32.77 ng/mL and 4.1 6,respectively.The PGⅠ and PGⅠ /PGⅡ ratio of patients suf-fering atrophic gastritis and gastric cancer were statistically significantly lower than those in patients suffering superficial gastritis (P <0.05).Conclusion The flow fluorescence assay could conduct simultaneous detection of PGⅠ and PGⅡwith good methodo-logical performance and high efficiency.The determination of PGⅠ and PGⅡlevels through flow fluorescence assay could provide laboratory basis for the screening and diagnosis of atrophic gastritis and early gastric cancer.

Objective Diabetic mellitus is one of the major threats to human health.The prevalence of diabetes mellitus is growing rapidly worldwide.Patients with diabetes mellitus are at increased risk for cardiovascular diseases.Diabetic cardiomyopathy (DC) is related to diabetes-specific metabolism,but the mechanism is not entirely clear.Recent studies suggest that abnormal myocardial energy metabolism and reduced number of myocardial cells may be the important pathophysiological mechanism that leads to heart function impairment of diabetes patients.Mitochondria are not only an important place generating cellular energy,also involved in the apoptotic and death process of cells.Therefore,mitochondrial dysfunctions play a key role in the process of DC.Mitochondrial permeability transition (MPT) is a center for information exchange within and outside the mitochondria and plays a key role in the maintenance of mitochondrial function.MPT works through the mitochondrial permeability transition pore (MPTP).In our recent studies,it was found that MPTP function changed in DC and its abnormality could be corrected by specific AT I receptor antagonist.These findings are important for better understanding DC.
