Objective To investigate the clinical efficacy and safety of microcatheter assisted trabeculectomy on the treatment of childhood glaucoma.Methods A prospective case series method was performed.Sixteen childhood glaucoma with 22 eyes were enrolled in Henan Eye Hospital and Zhengzhou Second People's Hospital from December 2016 to August 2017.Nine males with 12 eyes and 7 females with 10 eyes were included,and the age ranged from 6 months to 8 years (median 4 years).All the subjects underwent microcatheter assisted trabeculectomy.The intraocular pressure changes were observed preoperation and 7 days,1 month and 6 months after surgery,and the postoperative complications were analyzed.This study was approved by the Ethics Committee of Henan Eye Hospital (2018KS-01) and Zhengzhou Secord People's Hospital (No.20161202001),and adhered to the tenets of the Declaration of Helsinki.Written informed consent was obtained from each guardia prior to any medical examination.Results Twenty eyes of 14 patients underwent microcatheter assisted trabeculectomy,the success rate was 90.91％.Twelve eyes were operated with full incision (incision range was 360°),8 eyes were performed with subtotal incision (incision range was 180°-330°),while the microcatheter could not pass over 90° in 2 eyes and was switch to traditional Harms knife trabeculotomy-trabeculectomy intraoperatively.The intraocular pressures of the 20 eyes that underwent microcatheter assisted trabeculectomy preoperation,7 days,1 month and 6 months after surgery were (26.55 ±4.38),(20.48 ± 3.62),(13.71 ± 6.35) and (12.67 ± 5.37) mmHg,respectively.The intraocular pressures in patients at different time points were statistically significant (F=112.771,P＜0.001).At the last follow-up,the intraocular pressures of 18 eyes were controlled.Among them,16 eyes achieved completely controlled intraocular pressure while 2 eyes returned to normal intraocular pressure after using ocular hypotensive drugs.The intraocular pressure of 2 eyes increased again after operation,and the intraocular pressure could not be controlled after combined use of anti-hypertensive drugs.All patients had no serious complications during and after the operation.Different degrees of anterior chamber hemorrhage occurred in 16 eyes during the surgery,and all the hemorrhages were absorbed within 1 week after surgery.Conclusions For children with glaucoma,microcatheter assisted trabeculectomy can achieve good intraocular pressure reduction effect without serious complications.

ObjectiveTo explore the impact of autonomic nerve function on motor function in patients with post-stroke depression (PSD) from the perspective of regional homogeneity (ReHo). MethodsFrom January to December, 2020, a total of 60 inpatients and outpatients with cerebral infarction in the Affiliated Brain Hospital of Nanjing Medical University were divided into control group (n = 30) and PSD group (n = 30). Two groups were assessed using Fugl-Meyer Assessment (FMA), modified Barthel Index (MBI) and Hamilton Depression Scale (HAMD). Heart rate variability (HRV) was measured. Ten patients in each group were selected randomly to undergo resting state functional magnetic resonance imaging (rs-fMRI) to calculate ReHo. ResultsAll HRV indices were lower in PSD group than in the control group (|t| > 2.092, P < 0.05). In PSD group, FMA and MBI scores showed positive correlations with 24-hour standard deviation of normal-to-normal R-R intervals (SDNN), the root mean square of successive differences between normal heartbeats over 24 hours (RMSSD), the percentage of differences between adjacent normal R-R intervals over 24 hours that were greater than 50 ms (PNN50), total power (TP), very low frequency power (VLF) and low frequency power (LF) (r > 0.394, P < 0.05), and showed negative correlations with HAMD scores (|r| > 0.919, P < 0.001). HAMD scores in PSD group were negatively correlated with SDNN, RMSSD, PNN50, TP and VLF (|r| > 0.769, P < 0.001). Compared with the control group, the ReHo increased in PSD group in the right rectus gyrus (142 voxels, t = 6.575), the left medial and paracingulate gyri (204 voxels, t = 4.925) (GRF correction, P_-Voxel < 0.005，P_-Cluster < 0.05); and reduced in the right cerebellum (191 voxels, t = -6.487), the left middle temporal gyrus (140 voxels, t = -5.516), and the left precentral gyrus (119 voxels, t = -4.764) (GRF correction, P_-Voxel < 0.005，P_-Cluster < 0.05) in PSD group. ConclusionAutonomic nerve function is related to motor dysfunction in patients with PSD. The modulation of emotional, cognitive and motor brain regions by the autonomic nervous system may play a role in influencing the motor function in patients with PSD.
