Objective The selective deficit of recognition of disgust expression in Huntington’s disease (HD) and HD gene carrier strongly suggested the possibility that basal ganglia is involved in disgust processing. To further tested this hypothesis, we test the perception of emotional expressions in patients with symptomatic Wilson’s disease (WD), another basal ganglia disease resulted from abnormal copper metabo lism. Methods We developed a six basic emotional morphed face continuum (30 morphed emotional faces across happy surprise fear sad disgust anger happy). Participants were required to label each of these morphs in 5 trails to measure the ability of different emotion processing. The performances of 32 cases of WD were compared with 20 age and education matched normal controls. Results On the group level, although significantly impaired in fear, disgust and anger (correct identification scores: 12.8?3.6;9.1?4.7;14.9?4.3, P

8. Feasibility of 3D printing of mitral valve model based on echocardiographic data
Chinese Journal of Medical Imaging Technology 2020;36(4):489-493
Objective: To explore the feasibility of using 3D transesophageal echocardiography (3D-TEE) data to generate 3D patient-specific model of mitral valve (MV) using 3D printing. Methods: A retrospective study was performed in 30 patients, including 10 cases with normal MV, 10 cases with MV stenosis and 10 cases with MV prolapse. 3D-TEE volumetric data of 30 patients were acquired and postprocessed, and then soft MV models were made through injecting silicone into the molds. Measurements of MV annulus antero-posterior diameters, anterolaterior and posteromedial diameters, perimeter, area and MV opening width obtained from 3D-TEE images and from 3D models were compared, and the absolute differences of these values were calculated. Results: 3D-TEE volumetric data were successfully postprocessed, and then 3D MV models were made in all patients. The differences of MV parameters measured from 3D models were not statistically significant with those from 3D-TEE images (all P>0.05). Only less absolute differences of MV parameters were found between 3D models and 3D-TEE images. Conclusion: 3D printing of MV models based on 3D-TEE is feasible with high conserved fidelity.

Objective: To observe the regulatory effects of RhoA/ROCK pathway on the apoptosis of cardiac myocyte induced by anoxia and its mechanism. Methods: The model of cardiac myocyte anoxia was established. The beat pulsations and apoptosis rates after 1 h, 3 h, 6 h, 9 h and 12 h of anoxia were recorded and the expressions of RhoA, ROCK1/2, p-PI3K, p-AKT and caspae-3 were detected, too. The apoptosis and the expressions of related proteins were detected after RNAi of RhoA and the inhibition of ROCK by Y-27632. Results: The beat pulsations after 1 h, 3 h, 6 h, 9 h and 12 h decreased gradually but the apoptosis rates increased gradually, and the expressions of RhoA, ROCK1/2, p-PI3K, p-AKT and caspase-3 were increasing along with the increasing duration of anoxia. The apoptotic rates after 1 h, 3 h, 6 h, 9 h and 12 h of anoxia were (4.36[U+4F9D]0.98)%, (8.36[U+4F9D]2.12)%, (15.32[U+4F9D]3.62)%, (18.68[U+4F9D]4.83)% and (24.56[U+4F9D]6.22)%, respectively and decreased more significantly than control group in different time points of anoxia (. P<0.05), and the expressions of RhoA, ROCK1/2, p-PI3K, p-AKT and caspase-3 decreased significantly (. P<0.05). The apoptosis rate and the expressions of RhoA, ROCK1/2, p-PI3K, p-AKT and caspase-3 decreased significantly (. P<0.05) after the inhibition of ROCK by Y-27632 (. P<0.05). Conclusions: RhoA/ROCK pathway plays a critical role in the regulation of the apoptosis of cardiac myocyte induced by anoxia, which may be accompanied by regulating the activity of PI3K/AKT/Caspase-3 pathway.
