ABSTRACT
Objective:To explore the relationship between the dark triad, basic psychological needs satisfaction and guilty proneness.Methods:Totally 595 college students were randomly selected from Zhengzhou University.They were tested with the dirty dozen(DD), the balanced measure of psychological needs scale(BMPN) and guilt-proneness-5(GP-5). SPSS 22.0 and AMOS 21.0 were used for data analysis, including descriptive analysis, correlation analysis and confirmatory factor analysis. Bootstrap measure was used for mediating effect test.Results:(1)The correlation analysis showed that the dark triad (29(21, 37)), Machiavellianism (4(4, 8)) and psychopathy(5(4, 9)) were negatively correlated with guilty proneness (20(16, 23)), and the correlation coefficients were -0.10, -0.22 and -0.18 respectively(all P<0.01). While narcissism (16(12, 21)) was not correlated with guilty proneness ( r=0.04, P>0.01). The satisfaction of basic psychological needs (56(54, 60)) was positively correlated with guilty proneness ( r=0.31, P<0.01). (2)The relationship between the dark triad and guilty proneness was partially mediated by basic psychological needs satisfaction, and the mediating effect accounted for 62.96%. Conclusion:The dark triad influences guilty proneness through basic psychological needs satisfaction.
ABSTRACT
Objective To assess the value of transesophageal echocardiography (TEE) in left atrial appendage (LAA) closer with Amplatzer Cardiac Plug (ACP).Methods Consecutive 32 atrial fibrillation patients (CHADS2≥1) with high risk bleeding underwent LAA occlusion with ACP LAA occlusion device under the guidance of TEE.Measurements of LAA anchoring area diameter (AAD) and LAA anatomical orifice diameter (AOD) including maximum,minimum values,and LAA depth on 2 dimentional TEE (2D TEE) were conducted before closer device implantation.The outcomes of LAA occlusion were analyzed.Results Among 32 patients,27 cases achieved successful LAA occlusion,including 2 cases with peripheral leakage ≤5 mm,and 5 cases failed occlusion.Among 5 failed closed patients,3 cases with LAA AAD≥ 30 mm,1 case with LAA of short depth,and 1 case with anatomical variation of LAA of low position that access sheath could not be positioned in the LAA.LAA AAD maximum,minimum and LAA depth were (25.9±4.9)mm,(20.0±3.8)mm,(31.0±5.6)mm,respectively,and LAA AOD maximum,minimum diameters were (26.2±6.2)mm,(19.4±4.3)mm,respectively.Among 10 cases with LAA AAD≥30 mm,7 cases achieved successful LAA occlusion,but 3 cases failed.The implanted device diameter was (26.4±3.8)mm,and device compression rate was (7.6±5.5)%.The coefficient of correlation between device diameter and large LAA AAD and AOD is 0.770 and 0.717,respectively.There was no complication but 1 case with pericardial effusion.Conclusions Two dimentional TEE measurements of LAA have clinical guiding significance in the selection of proper size of ACP LAA occluder.The AAD of 2D TEE has the good correlation with ACP occluder′s size,the AADs are important factors which affect the success of LAA occlusion.
ABSTRACT
Objective To evaluate the clinical application value of 2-dimentional transesophogeal echocardiography (2D-TEE) ,real-time 3-dimensional transesophogeal echocardiography(RT-3D TEE) and left atrial appendage CT angiography ( LAA CTA ) before percutaneous left atrial appendage closure ( LAAC) with the Watchman occluder . Methods Consecutive 50 atrial fibrillation ( AF) patients underwent 2D-TEE ,RT-3D TEE and LAA CTA examination before LAAC . The number of LAA lobes ,the diameter of landing zone (DLZ) and the depth of LAA were measured by using different methods . The correlation between LAA landing zone diameters measured by different methods and device size were calculated . Results Among 50 patients ,there was no significant difference in lobe nubmers between RT-3D TEE and LAA CTA ( P >0 .05) . The maximum diameter of landing zone(DLZ) from LAA CTA was greater than those from RT-3D TEE and 2D-TEE ( t =3 .977 ,5 .373 ,both P<0 .05) ,and DLZ from RT-3D TEE was greater than that from 2D-TEE ( t=2 .124 , P <0 .05) . The value measured by RT-3D TEE was greater than that by 2D-TEE for the LAA minimum DLZ ( t =2 .142 , P < 0 .05) . LAA depth:CTA value was greater than 2D-TEE and RT-3D TEE values( t =2 .674 ,4 .066 ,both P < 0 .05) ,and 2D-TEE value was greater than RT-3D TEE value( t =2 .114 , P <0 .05) . The correlation coefficient of LAA maximum ,minimum DLZ and LAA depth between 2D-TEE and RT-3D TEE were 0 .638 ,0 .734 ,0 .647 ( all P =0 .000) ,and 0 .517 ,0 .338 and 0 .591 between RT-3D TEE and LAA CTA ,respectively ( all P <0 .05) ,and 0 .503 ,0 .359 and 0 .610 between 2D-TEE and LAA CTA ,respectively ( all P < 0 .05) . LAA DLZ of LAA angiography ( LAA-A) was ( 22 .6 ± 3 .5 ) mm . Fourty-seven AF patients achieved successful LAA occlusion with Watchman device and the size of closure was ( 27 .5 ± 3 .3) mm . Correlation coefficient between the size of device and LAA maximum DLZ by RT-3D TEE ,2D-TEE and LAA CTA were 0 .693 ,0 .647 ,0 .586 , respectively (all P = 0 .000) . Correlation between LAA-A and the size of device was the closest ( r =0 .914 , P =0 .000) .Conclusions The difference in LAA size measured by TEE and LAA CTA could be significant ,and need to be considered before the LAAC . 2D-TEE , RT-3D TEE and CTA LAA measurements all could play important roles in the selection of proper Watchman device size ,and the maximum DLZ of RT-3D TEE has the closest correlation with Watchman device size .
ABSTRACT
ObjectiveTo explore the value of virtual touch tissue quantification (VTQ) in evaluating Lauren classification of advanced gastric carcinoma.MethodsForty-one patients with gastric cancer proved by endoscopic biopsy performed preoperative VTQ examination,and the findings were compared with postoperative pathologic results via hematoxylin -eosin and Alcian Blue-Periodic Acid Schiff (AB-PAS) staining.ResultsIn 41 patients,26 cases were diagnosed as diffuse type and 15 cases as intestinal type by pathology after operation.The shear wave velocity(SWV) of diffuse type was higher than that of intestinal type [(1.72± 0.83)m/s vs (1.05± 0.66)m/s,t =2.819,P=0.008] measured by virtual touch tissue quantification (VTQ).According to the area under the ROC curve,the cut- off value of SWV in gastric cancer tissues for assessing the diffuse type was 1.045 m/s with a sensitivity of 80.8％ and specificity of 73.3 ％ respectively.ConclusionsVTQ could be considered as a promising method to distinguish the Lauren classification in patients with advanced gastric carcinoma.
ABSTRACT
ObjectiveTo explore the value of virtual touch tissue quantification (VTQ) in the evaluation of clinical pathological typing of advanced gastric cancer.MethodsFifty six patients who had been diagnosed as gastric cancer were examined using acoustic radiation force impulse.According to clinical pathological typing,all cases were divided into highly-moderately differentiated adenocarcinoma (14 cases) and non-highly-moderately differentiated adenocarcinoma (42 cases).A comparison with clinical pathologic results was made after surgery.The correlation of VTQ results and clinical pathological typing of gastric cancer was analyzed.ResultsThe VTQ value of highly-moderately differentiated adenocarcinoma was lower than that of non-highly-moderately differentiated adenocarcinoma [(1.49 ± 0.44) m/s vs (2.12 ± 0.45) m/s],with statistical significance( t =-4.53,P ＜0.05).According to the maximum area under the ROC curve,the cutoff value of VTQ was 1.795 m/s,the sensitivity and specificity were 78％ and 86％,respectively,the Youden's index was 0.64,and with high reproducibility(Kappa =0.81).ConclusionsVTQ could initial estimate the clinical pathological typing of advanced gastric cancer before operation.
