Objective To observe the effect of 3D-Slicer combined with sina software assisted minimally invasive neuroendoscopic surgery for hypertensive intracerebral hemorrhage,and investigate the application value of 3D-Slicer combined with sina software in the preoperative localization of minimally invasive neuroendoscopic surgery.Methods From July 2015 to October 2017,38 consecutive patients with supratentorial hypertensive intracerebral hemorrhage admitted to Shunde Hospital,Guangzhou University of Chinese Medicine were enrolled retrospectively.According to the different treatment methods,they were divided into an endoscopic group and a puncture group (n =19 in each group).The endoscopic group was treated with 3D-Slicer combined with sina software for neuroendoscopic hematoma removal,and the puncture group was treated with the hematoma minimally invasive soft-channel puncture and drainage under the CT localization.The effect of 3D-Slicer combined with sina software in the preoperative localization of hypertensive intracerebral hemorrhage by the minimally invasive surgery was evaluated by comparing the hematoma clearance of the first and third day of the two groups of patients after procedure,puncture to the preset position success,postoperative rebleeding,postoperative complications,and good prognosis at 3 months after procedure.Results The clearance rate of hematoma at the first day after operation in the endoscopic group was significantly higher than that in the puncture group ([90 ± 10]％ vs.[46 ± 16]％;t =2.348,P ＜ 0.05).The success of the puncture to the preset position was better than that in the puncture group (19/19 vs.14/19;x2 =5.758,P =0.016),and postoperative rebleeding rate was lower than that in the puncture group (0 vs.4/19;x2 =4.471,P =0.034).There were significant differences.There was no significant difference in postoperative infection complications between the two groups (all P ＞ 0.05).The prognosis of the endoscopic group was good in 17 patients within 3 months after procedure,and the prognosis was good in 11 patients in the puncture group.The good prognosis in the endoscopic group was better than that in the puncture group (x2 =4.866,P =0.027).Conclusion The effect of 3D-Slicer combined with sina software assisted minimally invasive neuroendoscopic surgery for hypertensive intracerebral hemorrhage was better than the hematoma minimally invasive soft-channel puncture and drainage under the CT localization,and the 3D-slicer combined with sina software can provide rapid and accurate preoperative localization for minimally invasive neuroendoscopic surgery of hypertensive intracerebral hemorrhage.

Objective:To investigate the differences of white matter diffusion properties between vulnerable and resistant individuals to continuous attention after sleep deprivation.Methods:According to the psychomotor vigilance test performance before and after sleep deprivation, the participants were divided into the vulnerable group( n=24) and resistant group( n=25). All participants underwent diffusion tensor imaging (DTI) scans.Tract based spatial statistics(TBSS) was used to compare fractional anisotropy(FA), mean diffusivity(MD), axial diffusivity(AD), radial diffusivity(RD) maps between the two groups.Spearman correlation analysis was conducted by SPSS 24.0 to investigate the relationships between the altered DTI metrics and PVT task performance. Results:(1) Compared with resistant group, FA value of vulnerable group decreased in the body of corpus callosum(x, y, z=-8, 9, 25, t=-7.855), right superior longitudinal fasciculus(x, y, z=-39, -7, 26, t=-6.252), bilateral anterior limb of internal capsule(x, y, z=-13, 8, 13, t=-5.235; x, y, z=12, 8, 3, t=-5.024) and right posterior thalamic radiation(x, y, z=-26, -56, 17, t=-5.469)(TFCE corrected, P<0.05, cluster size≥50 voxel). (2) Compared with resistant group, MD value of vulnerable group increased in the body of corpus callosum(x, y, z=-3, -6, 26, t=7.613), right superior longitudinal fasciculus(x, y, z=-31, -19, 38, t=5.314), bilateral anterior limb of internal capsule(x, y, z=-16, 7, 8, t=6.898; x, y, z=15, 5, 7, t=6.652), splenium of corpus callosum(x, y, z=27, -53, 17, t=6.541), and AD value increased in the right superior longitudinal fasciculus(x, y, z=-33, -19, 39, t=4.892), splenium of corpus callosum(x, y, z=-22, -49, 21, t=5.450), genu of corpus callosum(x, y, z=4, 26, 0, t=4.332), as well as RD value increased in the right superior corona radiata(x, y, z=-17, 1, 33, t=7.558), body of corpus callosum(x, y, z=4, -8, 26, t=6.699), right anterior limb of internal capsule(x, y, z=-12, 7, 3, t=5.212) (TFCE corrected, P<0.05, cluster size≥50 voxel). (3) Correlational analysis revealed that the negative correlations were found between PVT task performance and the FA value in the right superior longitudinal fasciculus( r=-0.492, P<0.001), right anterior limb of internal capsule( r=-0.510, P<0.001), right posterior thalamic radiation( r=-0.502, P<0.001) and body of corpus callosum( r=-0.464, P<0.001). The positive correlations were found between PVT task performance and the MD value in the body of corpus callosum( r=0.500, P<0.001), right superior longitudinal fasciculus( r=0.499, P<0.001), splenium of corpus callosum( r=0.462, P<0.001), right anterior limb of internal capsule( r=0.471, P<0.001), and AD value in right superior longitudinal fasciculus( r=0.643, P<0.001), as well as RD value in right superior corona radiate( r=0.498, P<0.001) (Bonferroni corrected, P<0.003). Conclusion:Differences in the microstructural characteristics of white matter fiber tracts in specific brain regions may constitute the potential neuropathological basis for the phenotypes of vulnerable and resistant individuals to continuous attention after sleep deprivation.
