Objective: Studying the relationship between the polymorphism of the apolipoprotein E(ApoE) gene and patients of hypertension. Methods: Using apolipoprotein E (ApoE) gene as a candidate gene, the ApoE gene genotype was determined in 70 patients with hypertension and 59 healthy subjects were studied by the polymerized chain reaction-restriction fragment length polymorphism(PCR-RFLP). Results: The ApoE gene genotype distribution was significantly in healthy subjects and in patients of hypertension(P

OBJECTIVETo innovatively establish a new platform of myocardial ischemia-reperfusion injury (MIRI) animal model by observing abnormal savda carrier MIRI indicators, and to observe changes of myocardial ultrastructure.

METHODSAccording to Uyghur medical theories, an abnormal savda carrier animal model was established and confirmed using multifactor, and then MIRI models set up. Totally 36 male white SD rats were randomly divided into the normal sham-operation group, the normal operation group, the model sham-operation group, and the model operation group, 9 in each group. ECG changes, myocardial enzymes (CK-MB), and cardiac troponin (cTnT), and ultramicrostructures were observed.

RESULTSCompared with the normal sham-operation group, some damage of ultramicrostructures occurred in heart muscles of rats in the normal operation group and the model operation group, such as lowered myoplasm density, loosely arranged myofilament, dilated myofibris, reduced mitochondria number, vacuole and swelling mitochondrion. Ultramicrostructural damage of cardiac muscle cells was more severe in rats of the model operation group. Compared with the normal sham-operation group, CK-MB and cTnT increased in the normal operation group with statistical difference (P < 0.01). Compared with the normal sham-operation group, there was no statistical difference in CK-MB or cTnT in the model sham-operation group (P > 0.05). Compared with the model operation group, CK-MB and cTnT obviously decreased in the model sham-operation group and the normal operation group with statistical difference (all P < 0.01).

CONCLUSIONAbnormal savda carrier MIRI model established in this experiment could provide favorable conditions for further MIRI intervention treatment.
