Objective:To investigate the changes in brain functional network and structural-functional network coupling in children with drug-resistant epilepsy (DRE), and to analyze their correlation with cognitive function, disease duration, and age of onset.Methods:This study was a cross-sectional study. Clinical and imaging data of 19 children with DRE who received consultation and treatment at the Affiliated Hospital of Zunyi Medical University from August 2021 to August 2023 (DRE group) were prospectively included. Another 27 age-and sex-matched healthy children were collected as the healthy control group. All subjects had 3D-T 1WI, T 2 fluid-attenuated inversion recovery, diffusion tensor imaging (DTI), resting-state functional magnetic resonance imaging (rs-fMRI) scans and Wechsler Intelligence Scale assessments. Independent sample t-test and Mann-Whitney U test were used to analyze the global and local topological attributes, as well as the structural-functional coupling (SFC) values at the whole brain and modular levels in two groups. Correlations between abnormal resting state brain functional network indicators and the Wechsler Intelligence Scale score [verbal comprehension index (VCI), perceptual reasoning index (PRI), working memory index (WMI), processing speed index (PSI), full scale intelligence quotient (FSIQ)], disease duration and age of onset was evaluated using a Spearman or Pearson correlation analysis. Results:Compared to the healthy control group, DRE group exhibited decreased VCI, PRI, WMI, PSI, FSIQ and the differences were all statistically significant (all P<0.05). Both brain functional networks had small world attributes. There was a statistically significant difference in the area under the curve of sparsity of degree centrality (DC) in the left pallidum between the DRE group and healthy control group (2.998±0.942, 4.992±1.945, t=-4.07, FDR corrected P<0.05). Compared with the control group, the DRE group had decreased SFC within the limbic network (LN) ( P<0.05), increased SFC within the sensorimotor (SMN) ( P<0.05), decreased SFC between the default mode network-LN ( P<0.05), and increased SFC between the SMN-attentional network (AN) ( P<0.05). There was no statistically significant difference in SFC at the whole brain level between the two groups. Correlation analysis indicated that DC in left pallidum in DRE group negatively correlated with the PSI ( r=-0.537, P=0.018), and SFC between the SMN and AN demonstrated a negative correlation with age of onset ( r=-0.537, P=0.018). Conclusion:The altered DC in left pallidum may be related to cognitive impairment in children with DRE, providing biomarker information for the study of neural mechanisms in children with DRE.

Objective:To investigate the feasibility and clinical efficacy of side-to-side anastomosis of superficial temporal artery (STA) and middle cerebral artery (MCA) bypass using in-situ intravascular suture technique.Methods:A retrospective analysis was conducted on the clinical data of 10 adult patients who were treated with side-to-side microvascular anastomosis of STA-MCA bypass to improve intracranial blood supply, between February 2024 and September 2024 in the Department of Neurosurgery of the Fourth Affiliated Hospital of Soochow University. Among the patients, 2 were of symptomatic MCA occlusion and 8 of Moyamoya disease. Diameter of STA and MCA, length of anastomosis and blocking time of MCA were recorded. Indocyanine green video angiography (ICG-VA) was performed to evaluate the immediate patency of the STA-MCA side-to-side anastomosis. Digital subtracted angiography (DSA) was performed at 1 week after the surgery to evaluate the patency of the STA-MCA bypass anastomosis, then follow-up DSA was performed at 1, 3 and 6 months after surgery to further evaluate the postoperative anastomotic patency. Neurological function was evaluated regularly with the modified Rankin Scale (mRS).Results:All of the 10 side-to-side STA-MCA bypass anastomoses were successfully performed using in-situ intravascular suture technique. The scalps of all patients healed well. The diameters of STA and MCA were 1.4-2.0 (1.76±0.27) mm and 0.8-1.4 (0.98±0.20) mm, respectively. The average length of the anastomoses was 3.5-5.0 (4.45±0.60) mm. The blocking time of MCA was 12.0-29.0 (21.50±6.62) min. A 100% vessel patency rate was achieved immediately after vessel anastomosis and at 1 month after surgery. DSA examinations were performed at 3 months after surgery on 6 patients and at 6 months after surgery on 1 patient, and all the anastomoses were found in full patency. All patients were included in the postoperative follow-up that lasted for 3 to 7 months. All patients recovered well without new neurological dysfunction. The mRS of 8 patients remained at 0 point before and after surgery. Two patients had improved postoperative mRS of 1 point from that of 2 points before surgery.Conclusion:STA-MCA side-to-side microvascular bypass anastomosis can be performed safely and efficiently using in-situ intravascular suture technique. It could efficiently reduce the incidence of perioperative complications. Meanwhile, it can self-regulate the blood flow and maximise the potential capability of STA.

Objective:To investigate the clinical curative effect of hyperbaric oxygen（HBO）combined with total arthroscopy in the treatment of popliteal cyst.Methods:From June 2015 to January 2020，the clinical data of 85 patients with popliteal cyst who received total arthroscopic minimally invasive surgery in Department of Orthopedics，Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and Department of Adult Orthopedics，Xinhua Hospital Chongming Branch were collected. According to different treatments，patients were divided into observation group（ n=45）and control group（ n=40）. The control group received total arthroscopic minimally invasive surgery while the observation group was additionally treated by hyperbaric oxygen therapy. Visual analogue scale（VAS）was used to evaluate the pain during the 72 hours after operation. Postoperative ambulation time and length of hospital stay were also recorded. Lysholm scoring system was used to evaluate knee function. The therapeutic efficacy was assessed by Rauschning-Lindgren grading. All the patients were followed up for one year to record the recurrence of cysts. Results:After treatment，the postoperative ambulation time and length of hospital stay of the observation group were obviously reduced compared with those of the control group，and its VAS score was lower than that of the control group，with significant statistical differences（ P<0.05）. The Lysholm scores of the two groups seven days after treatment were significantly higher than that before treatment，and the Lysholm score of the observation group markedly was higher than that of the control group after treatment，with significant statistical difference（ P<0.05）. After treatment，the total effective rate of the observation group（93.3%）was remarkably higher than that of the control group（77.5%），with significant statistical difference（ P<0.05）. The recurrence rate of popliteal cyst in the observation group（6.7%）was significant different from that in the control group（17.5%）（ P<0.05）. Conclusion:HBO combined with total arthroscopic minimally invasive surgery in the treatment of popliteal cyst has the advantages of small incision，light pain，rapid recovery，which can quickly restore the function of knee joint with low recurrence rate and significant curative effect.
