ObjectiveTo explore the effect of fingolimod (FTY720) on secondary nerve injury after thalamic-ventricle hemorrhage (TH-IVH) in rats.MethodsAdult male Sprague Dawley rats (clean animal) were randomly divided into 3 groups: sham group, TH-IVH group, and intervention group (FTY720 group), with 6 rats in each group. TH-IVH model was established in both TH-IVH group and FTY720 group, but only the rats in FTY720 group were treated with FTY720. The observation was conducted at the 1st, 3rd and 7th day after modeling. The main observation index included scores of neurological function, change of body weight, water content of brain tissue, the activation of inflammatory cells, the degree of neuronal degeneration and apoptosis, and the level of cell autophagy.ResultsAt the 1st, 3rd and 7th day after modeling, the change of body weight, the neurological score, brain edema and microglia activation in TH-IVH group were statistically different from those in sham group and FTY720 group (P<0.05). The number of degenerated neurons and the number of apoptotic cells in TH-IVH group were statistically different from those in sham group and FTY720 group at the 1st and 3rd day after modeling (P<0.05). The differences in the ratio of LC3Ⅱ/LC3Ⅰ protein expression andBcl-2/Bax expression were statistically significant between FTY720 group and TH-IVH group at the 1st and 3rd day after modeling (P<0.05).ConclusionsFTY720 can improve neurological function of the TH-IVH model in the acute phase, and has certain neuroprotective effect. The neuroprotective effect of FTY720 may be associated with neuronal autophagy and apoptosis regulation and immunosuppression.
ObjectiveTo investigate the application of stereoelectroencephalography (SEEG) in the refractory epilepsy related to periventricular nodular heterotopia (PNH). MethodsTen patients with drug-resistant epilepsy related to PNHs from Guangdong Sanjiu Brain Hospital and the First Affiliated Hospital of Jinan University from April 2017 to February 2021 were studied. Electrodes were implanted based on non-invasive preoperative evaluation. Then long-term monitoring of SEEG was carried out. The patterns of epileptogenic zone (EZ) were divided into four categories based on the ictal SEEG: A. only the nodules started; B. nodules and cortex synchronous initiation; C. the cortex initiation with early spreading to nodules; D. only cortex initiation. All patients underwent SEEG-guided radiofrequency thermocoagulation (RFTC), with a follow-up of at least 12 months. ResultsAll cases were multiple nodules. Four cases were unilateral and six bilateral. Eight cases were distributed in posterior pattern, and one in anterior pattern and one in diffused pattern, respectively. Seven patients had only PNH (pure PNH) and three patients were associated with other overlying cortex malformations (PNH plus). The EZ patterns of all cases were confirmed by the ictal SEEG: six patients were in pure type A, two patients were in pure type B, one patient in type A+B and one in type A+B+C, respectively. In eight patients SEEG-guided RF-TC was targeted only to PNHs; and in two patients RFTC was directed to both heterotopias and related cortical regions. The mean follow up was (33.4±14.0) months (12 ~ 58 months). Eight patients (in pure type A or type A included) were seizure free. Two patients were effective. None of the patients had significant postoperative complications or sequelae. ConclusionThe epileptic network of Epilepsy associated with nodular heterotopia may be individualized. Not all nodules are always epileptogenic, the role of each nodule in the epileptic network may be different. And multiple epileptic patterns may occur simultaneously in the same patient. SEEG can provide individualized diagnosis and treatment, be helpful to prognosis.
ObjectiveTo analyze safety and feasibility of transumbilical single-incision laparoscopic assisted ventriculoperitoneal shunting. MethodsThe clinical data of 36 patients who diagnosed as hydrocephalus underwent ventriculoperitoneal shunting from May 2013 to August 2015 in this hospital were collected. Twelve patients were performed transumbilical single-incision laparoscopic assisted ventriculoperitoneal shunting (laparoscopy group) and 24 patients were performed laparotomy ventriculoperitoneal shunting (laparotomy group). The abdominal operation time, postoperative exhaust time, postoperative hospital stay, postoperative pain score, and postoperative complications rate were compared between the laparoscopy group and the laparotomy group. ResultsAll the operations were completed successfully. Compared with the laparotomy group, the abdominal operation time (P < 0.05), postoperative exhaust time (P < 0.05), and postoperative hospital stay (P < 0.05) were significantly shorter, the postoperative pain score was significantly less (P < 0.05) in the laparoscopy group. The postoperative complications rate had no significant difference between the laparoscopy group and the laparotomy group (P > 0.05). ConclusionsThe preliminary results of limited cases in this study show that transumbilical single-incision laparoscopic assisted ventriculoperitoneal shunting is safe and feasible, with better cosmetic. more comparative studies or randomized controlled trials are required to make a confirmed conclusion.
Objective To systematically review the clinical effectiveness and safety of programmable valves (PV) vs. standard valves (SV) for hydrocephalus. Methods Literature search was conducted in PubMed, The Cochrane Library, EMbase, CNKI, CBM, VIP and WanFang Data to collect both randomized controlled trials (RCTs) and non-randomized concurrent controlled trials on hydrocephalus treated by PV and SV published from January 1992 to January 2012. According to the inclusion criteria, two reviewers independently screened articles, extracted data, and evaluated and cross-checked the quality of the included studies. Then meta-analysis was performed using RevMan 5.0 software. Results A total of 11 non-randomized concurrent controlled trials involving 1,485 participants were included. The results of meta-analysis showed that, compared with SV, PV was superior in overall effective rate (RR=1.14, 95%CI 1.03 to 1.27, P=0.01), 2-year survival rate (RR=1.25, 95%CI 1.04 to 1.51, P=0.02), secondary surgery rate (RR=0.53, 95%CI 0.39 to 0.73, Plt;0.001), overall complications rate (RR=0.62, 95%CI 0.51 to 0.76, Plt;0.001), and over-drainage/ under-drainage rates (RR=0.42, 95%CI 0.21 to 0.83, P=0.01). But there were no significant differences in 1-year survival rate (RR=1.04, 95%CI 0.91 to 1.19, P=0.55), postoperative infection rate (RR=1.08, 95%CI 0.73 to 1.60, P=0.71) and valve related complication rate (RR=0.80, 95%CI 0.56 to 1.21, P=0.20) between the two groups. Conclusion Current evidence suggests that PV is superior to SV in increasing the effective rate, decreasing complications, and prolonging the long-term survival rate. Because of the limitation of quantity and quality of the included studies, more high quality, multicenter and double-blind RCTs are needed to prove whether PV can be clinically recommended as a preferred drainage surgery or not.
