Objective:To detect the functional role of Fascin1 and its related molecular mechanisms in migration and invasion capacity of glioma cells,we utilized gene specific small interference RNA of Fascin1 in cell line U87 MG. Methods:Fascin1-siRNA or negative siRNA was transfected into U87 MG cells of control group or experiment group. Transwell method was employed to assess the migration and invasion capacity of glioma cells. Western blot analysis was used to detect the protein expression of Fascin1,pAKT and pSTAT3. The impact of PI3K/AKT pathway and STAT3 pathway on migration and invasion of U87 MG cells was verified,via applying LY294002 and LY294002,which was inhibitor of the two pathways respectively. Results:As compared to control groups,the migration and invasion capacity of transfected glioma cells were attenuated about 52% or 43%(P<0. 05),accompanied with the decreased phos-phorylation of AKT and STAT3. As utilizing the inhibitors of AKT and STAT3,attenuated migration and invasion capacity of U87 MG cells were observed. Conclusion:Down-regulated expression of Fascin1 could suppress the migration and invasion capacity of U87 MG cells by inhibiting the phosphorylation of PI3K/AKT pathway and STAT3 pathway.

Objective Few studies are reported on the clinical characteristics of glioma-related epilepsy (GRE).Postoperative recurrence of epilepsy in some patients seriously affects their recovery.We aimed to explore the duration, frequency and type of the epileptic seizure as well as possible factors for postoperative recurrence of epilepsy.Methods We recorded the frequency and duration of epileptic seizures, analyzed the recurrence-related factors using the Cox regression model, and investigated the risk factors of recurrent epilepsy.Results The postoperative recurrence of epilepsy was found in 24 (26.97%) of the 89 cases, which, compared with the 65 non-recurrence cases, had a significantly longer seizure duration (7[3-10] vs 5[2-9] min, P<0.05) and higher onset frequency (6.5[4-9] vs 5[3-9] times/mo, P<0.05) preoperatively.After surgery, the 24 recurrence cases showed a remarkably reduced seizure duration (1[0.5-2.0] min, P<0.05) and onset frequency (1.5[1-3] times/mo, P<0.05).The main risk factors for epileptic recurrence included the level of the glioma-involved site (HR=6.728, 95% CI: 2.994-15.116), peritumoral edema (>2 cm) (HR=2.867, 95% CI: 1.210-6.795), brain wave type (HR=2.501, 95% CI: 1.058-5.914), and preoperative frequency of epileptic seizure (>6 times/mo) (HR=5.100, 95% CI: 2.437-10.677).Conclusion Postoperative recurrence of epilepsy is associated with the clinical pathological parameters, and the changes of the frequency and duration of epileptic seizures before and after surgery may provide some new theoretical reference for the treatment and prognosis of the disease.

BACKGROUND:The aim of spinal mobilization and spinal manipulation is to correct vertebral subluxation. However, facet joint pressures are not clear during these two therapies.
OBJECTIVE:To compare human lumbar facet joint pressures during simulated high-velocity, low-amplitude spinal manipulationversuslow-velocity, low-amplitude spinal mobilization.
METHODS:Totaly 12 adult fresh lumbar spinal specimens (T12-S2) were divided into two groups randomly. Parameters of simulated spinal mobilization (n=6): preload angle 15° (speed 3°/s), maximum angle 20° (speed 1°/s), with 9 N horizontal force to L5 spinous process. Parameters of simulated spinal manipulation (n=6): preload angle 15° (speed 3°/s), impulse angle 20° (impulse speed 33°/s), with 22 N horizontal force to L5 spinous process. Pressures of bilateral L4-5/L5-S1 facet joints were measured with Tekscan system.
RESULTS AND CONCLUSION:(1) During two spinal manipulative therapies (rotation to the right and then back to the neutral position), pressures of right facet joints decreased first and then increased gradualy, while pressures of left facet joints changed oppositely. (2) Pressures of right facet joints were similar regardless of manipulation type (P > 0.05). The maximum pressure of left facet joints was larger during manipulation than that during mobilization (P < 0.05). (3) Descending speed of pressures of right joint was larger during manipulation than that during mobilization (P < 0.01), and no significant difference in ascending speed of pressure of right facet joints was detected (P > 0.05). Both ascending and descending speeds of the left facet joints were larger during manipulation than that during mobilization (P < 0.01). (4) During two spinal manipulative therapies, pressures of ipsilateral facet joints decreased first and then increased, while pressures of contralateral facet joints increased first and then decreased. Joint pressure after treatment restored to that before treatment. (5) Impulse speed and magnitude of pressures of facet joints during manipulation were larger than that during mobilization. Facet joints are more possible to be injured during manipulation than that during mobilization. During manipulation, we should pay attention to the speed and intensity of the impact.

Objective To explore expression of HMGB1 in glioma tissue of glioma-related epilepsy patients. Methods Immunohistochemistry was used to detect the expression of HMGB1 in the tissues from 82 glioma-related epi?lepsy patients (glioma-related epilepsy group), 80 glioma patients (glioma without epilepsy group), 80 intractable epilepsy patients (epilepsy control group) epileptogenic foci tissue and 20 normal controls (negative control group). Results HMGB1 in glioma tissue of glioma-related epilepsy group was significantly higher than that in glioma tissue of glioma without epilepsy grou p (χ2=16.944, P<0.001), especially in low pathological grade glioma tissue. HMGB1 was higher in glioma tissue of glioma-related epilepsy group than in epileptogenic foci tissue of epilepsy control group (χ2=26.094, P<0.001). Expression of HMGB1 in glioma tissue of glioma without epilepsy group (χ2=32.273, P<0.001) and epileptogenic foci tissue of epilepsy control group ( χ2=22.236,P<0.001) was higher than in normal brain tissue of negative control group. In glioma-related epilepsy group, HMGB1 was positively correlated with seizures duration(r=0.365,P=0.001), sei? zures frequency (r=0.531,P=0.000) and pathological grade of glioma tissue (r=0.265,P=0.016). Conclusions HMGB1 is highly expressed in glioma tissues of glioma-related epilepsy; HMGB1 expression is closely related with seizures; and HMGB1 in glioma tissue may contribute to the formation of glioma-related epilepsy.

Wall filtering is a key technology in ultrasound color flow imaging system. Without efficient suppression of wall signal originating from stationary and moving tissue, low velocity blood flow cannot be measured, and the estimates of higher velocities will have a large bias. Among the various wall filters, the projection-initialized infinite impulse response (IIR) wall filter has narrow transition bandwidth and high stopband suppression ratio; it is superior to other wall filters. At present, the related literatures are only limited to theoretical research on this kind of filter, and no feasible design and implementation methods are reported. In this paper, a new design and implementation scheme for the projection-initialized filter is proposed, which transforms the filtering process to matrix multiplications. The proposed scheme is realized on programmable logic devices. Experimental results show that it is a simple and effective implementation method for projection-initialized IIR filter, and it is superior to conventional wall filters.
