Objective To investigate the relativity for weight of macrosomia predicted by ultrasound and clinical measurements . Methods 1 037 subjects who were delivered in May to November 2012 ,in Chongqing Health Center for Women and Children ,were collected and analyzed satistically .The parameters for the comparisons included maternal abdominal circumference (MAC) ,fundal height(FH) ,and fetal diameters measured by ultrasonic imaging such as biparietal diameter (BPD) ,head circumference(HC) ,femur length(FL) ,and abdominal circumference(AC) .The coincidence was calculated with real weights and compared with clinical predic-tions .Results When FH+ MAC 134 cm ,the accuracy of preliminary screening for macrosomia is the highest ,the area under the ROC curve is 0 .895 .Combining with the abdominal circumference(AC) by prenatal ultrasound ,the highest prediction rate of mac-rosomia is 75 .2% .when Fetal AC≥37 cm ,macrosomia incidence rate took 91 .7% .Conclusion Pregnant women with FH+MAC<134 cm ,whose incidence of Macrosomia is low .While if the FH+MAC≥134 cm ,combining with the prenatal ultrasound whose fetal AC>36 cm ,especially ≥37 cm ,the possibility of macrosomia is very high .

The human striatum is essential for both low- and high-level functions and has been implicated in the pathophysiology of various prevalent disorders, including Parkinson's disease (PD) and schizophrenia (SCZ). It is known to consist of structurally and functionally divergent subdivisions. However, previous parcellations are based on a single neuroimaging modality, leaving the extent of the multi-modal organization of the striatum unknown. Here, we investigated the organization of the striatum across three modalities-resting-state functional connectivity, probabilistic diffusion tractography, and structural covariance-to provide a holistic convergent view of its structure and function. We found convergent clusters in the dorsal, dorsolateral, rostral, ventral, and caudal striatum. Functional characterization revealed the anterior striatum to be mainly associated with cognitive and emotional functions, while the caudal striatum was related to action execution. Interestingly, significant structural atrophy in the rostral and ventral striatum was common to both PD and SCZ, but atrophy in the dorsolateral striatum was specifically attributable to PD. Our study revealed a cross-modal convergent organization of the striatum, representing a fundamental topographical model that can be useful for investigating structural and functional variability in aging and in clinical conditions.
