Marital quality is closely related to individual health. It is the main reason for many couples to terminate assisted reproductive technology (ART) treatment, otherwise it also has been proved to be significantly related to curative effect of ART. With the development of preimplantation genetic testing (PGT), ART is bound to have a wider range of people to adapt in the future. PGT includes two main processes, in vitro fertilization (IVF) and genetic testing. In addition to traditional infertile couples, couples at high-risk of genetic diseases is also a common indication for PGT, which means that comparing to infertile women or IVF women, marital quality of PGT women is more complicated. Firstly, this review introduced the current methodology on marital quality, and basis of summarizing research results of marital quality of IVF women, according to different indications, we put forward potential problems of marital quality of PGT women. Finally, in the light of domestic research status of marital quality, we referred to some research limitations, in order to provide a theoretical basis for further research on marital quality of PGT women.

The purpose of this study was to analyze morphological and functional changes in the left ventricular muscle mass and vessel diameters of the arteries in young competitive athletes of various sports and evaluate the correlation between the heart and arterial vessel under the training environment in this latter half of the growth period. The subjects were 51 male college student athletes (mean age, 19.6±0.4 years) of 6 competitive sports (archery, weight lifting, swimming, short-distance races, middle-distance races, and long-distance races) . The diameters of the right and left common carotid arteries, right and left radial arteries, right and left foot dorsal arteries, and the aorta and the left ventricular muscle mass (LVM) were measured by Doppler echocardiography. To minimize the influences of the physique and body weight associated with growth and sport types, all data obtained by measurement were corrected by body surface area. The sum of the diameters of all the above arteries (total arterial diameter : TAD) was obtained to evaluate its correlation with the left ventricular muscle mass. The diameter of the foot dorsal artery was significantly higher in the long-distance runners than in the sprinters (P<0.05) . The diameter of the radial artery according to the 6 types of sport was the highest for weight lifting, followed in order by archery, longdistance races, middle-distance races, swimming, and short-distance races, showing a significant difference between weight lifting and short-distance races (P<0.05 ) . TAD was high for generalized endurance sports and correlated with the left ventricular muscle mass (r=0.893) . Thus, the arterial diameters significantly differed among competitive sports and were particularly increased for endurance exercise. The diameters of the local arteries used for local exercise were also increased. When TAD as a new parameter and its ratio per body surface area were calculated, there was a high correlation between the heart (left ventricular muscle mass) and the arterial diameter. These results suggest that exercise adaptation can he evaluated in the arterial system in svstemic circulation as well as the nervous and muscular systems.
