Fetal heart rate variability in growth restricted fetuses
Intrauterine growth restriction (IUGR) remains a major problem in perinatal medicine because of the variety of its underlying causes and the prediction of its outcome. Characteristics of heartbeat interval patterns are associated with neuro-vegetative and humoral regulatory processes. Fetal magnetocardiography allows non-invasive assessment of these processes with high precision throughout the second half of gestation. The aim of our study was the analysis of linear and non-linear parameters of fetal heart rate fluctuations to distinguish between IUGR fetuses and a cohort of normal subjects, both pre-selected from heart-rate traces representing a quiet state of activity in the third trimester of gestation.
Objective To investigate the relationship between FcγRⅢB gene polymorphisms and susceptibility to chronic periodontitis in Chinese patients. Methods DNA samples with buccal swabs were collected from 63 severe CP patients, 103 initial to moderate CP patients, and 80 healthy controls in Chinese Han nationality. The FcγRⅢB gene polymorphisms were analyzed with PASA. Results There were no significant genotype distribution differences of FcγRⅢB between any two of the three subject groups. Conclusion Further study was needed since we did no find the relationship between the FcγRⅢB gene polymorphism and periodontitis in this present study.
