Objective To investigate expression of Human papillomavirus (HPV) 11 type E7 protein antigen in prokaryotic cells and its potential use for the serodiagnosis of condyloma acuminatum (CA).Methods The full-length gene encoding for HPV11 E7 protein was amplified by PCR,and cloned into vector pET32a(+) to form recombinant pET32a(+)/HPVll E7 plasmid.The fusion His-E7 protein was expressed and analyzed by using SDS-PAGE and Western blotting.Using ELISA assay,HPV11 E7 fusion protein were also used to screen human serum IgG antibody from 93 patients with CA,43 patients with cervix cancer and 58 healthy control subjects.Results Highly expressed fusion His-E7 protein was obtained,and purified protein served as a special diagnostic antigen to screen human serum antibody for CA serodiagnosis.It showed that CA group,cervix cancer group and healthy control human serum IgG antibody average value were 1.545?0.131,0.586?0.155 and 0.674?0.150 respectively,positive rate were 76.3% (71/93),11.6% (5/43) and 5.2% (3/58).There was significantly difference between the CA group to compare cervix cancer group and healthy control (P

OBJECTIVETo investigate the role of mitochondrial calcium uniporter in cardioprotection elicited by ischemic postconditioning (Postcond).

METHODSMale Sprague-Dawley rats were used for Langendorff isolated heart perfusion. The hearts subjected to global ischemia for 30 min followed by 120 min of reperfusion. Left ventricular developed pressure (LVDP), maximal rise/fall rate of left ventricular pressure (± dP/dtmax) were measured. The level of lactate dehydrogenase (LDH) in the coronary effluent was measured spectrophotometrically, the content of formazan of myocardium was also measured at the end of reperfusion.

RESULTCompared to I/R group, Postcond had an significant increase in the mechanical function of the left ventricle, with LDH release reduced and the content of formazan increased. Spermine, the opener of mitochondrial calcium uniporter, deteriorated the mechanical function of left ventricle and decreased the formazan content, and increased LDH release. Ruthenium red, the inhibitor of mitochondrial calcium uniporter, increased the mechanical function of the left ventricle, decreased the LDH release, but the content of formazan was not increased.

CONCLUSIONThe inhibition of mitochondrial calcium uniporter is involved in the mechanisms of ischemic postconditioning.
