Objective To investigate the effects of down-regulation of Netrin-1 expression on cell proliferation,apoptosis and migration of a cutaneous squamous cell carcinoma(CSCC)cell line SCL-1.Methods Unspecific(control)small interference RNA(siRNA)and Netrin-1-targeting siRNA were designed and constructed.SCL-1 cells were divided into 3 groups to remain untreated(control group 1),be transfected with control siRNA(control group 2)and Netrin-l-targeting siRNA(experiment group)by using Lipofectamine 2000 respectively.After 48 hours of additional culture,flow cytometry was performed to detect the apoptosis of cells,Western blot to determine the protein expression of caspase-3 and-9,Netrin-1 and matrix metalloproteinases (MMP)in these cells,and Boyden chamber was utilized to evaluate the migration of cells.Enzyme linked immunosorbent assay(ELISA)was performed with cholecystokinin-8(CCK-8)kit to estimate the proliferation of cells at 24,48,72 and 96 hours after the transfection.Results The expression of Netrin-1 protein was significantly downregulated in SCL-1 cells in the experiment group compared with the control group 1 and 2 (0.207 ± 0.044 vs.0.741 ± 0.111 and 0.716 ± 0.109,F =31.43,P ＜ 0.05).The Netrin-1-targeting siRNA significantly downregulated the proliferation of SCL-1 cells,but induced the apoptosis in SCL-1 cells with significant differences in the percentage of early apoptotic cells and late apoptotic cells between the control group 1,2 and experiment group(11.74 ± 0.33 vs.11.55 ± 1.22 vs.24.74 ± 2.43,F=68.63,P＜ 0.01;3.82 ± 0.32 vs.4.69 ± 0.68 vs.5.33 ± 0.18,F =8.58,P ＜ 0.05).The experiment group showed a significant increase in the expression of caspase-3 and-9(1.458 ± 0.111 vs.0.398 ± 0.057 and 0.412 ± 0.049,F =183.99,P ＜ 0.01;0.967 ± 0.099 vs.0.234 ± 0.036 and 0.205 ± 0.033,F =138.11,P ＜ 0.01),but a statistical decrease in the expression of MMP-2(0.235 ± 0.038 vs.0.862 ± 0.040 and 0.892 ± 0.035,F =291.07,P ＜ 0.01)compared with the control group 1 and 2.Conclusions The down-regulation of Netrin-1 expression can suppress the proliferation and migration of SCL-1 cells,but promote the apoptosis in SCL-1 cells.

Objective The immunocytochemical localizations of GABA\-A\| and GABA\-B\|receptor in the mesencephalic trigeminal nucleus(Vme) of the rat were examined in order to provide morphological evidence for a possible functional analysis of GABA\|receptor in the transmission and modulation of the orofacial region trigeminal proprioceptive sensory information. Methods An immunocytochemical staining method was used in the present study,and immunostained sections were observed under light microscope. Results Many neuronal cell bodies,fibers and terminals with dense GABA\-A\| and GABA\-B\|receptor\|like immunoreactivity(\|LI) were observed to be localized in Vme,and different subunits of GABA\|receptor\|LI showed the morphological difference in their distribution:1.Immunoreactivity for GABA\-B R1 subunit was intensely distributed in the cell bodies of Vme neurons,whereas the weak immunoreactivity for GABA\-BR2 subunit was only observed in the region surrounding the somata of Vme neurons which showed negative GABA\-BR2\|LI;2.A considerable number of GABA\-A\|like immunoreactive neurons,fibers and terminals were also found in Vme.It was involved four kinds of subunits(?1,?2,?3 and ?).The heavy immunoreactivity for GABA\-AR?1 and GABA\-AR?3 subunits were only seen in the cell bodies of Vme neurons.On the other hand,the immunoreactivity for GABA\-AR?2 and GABA\-AR? subunits was only observed in the fibers and terminals in the region surrounding the somata of Vme neurons,which showed negative immunoreactivity for above subunits;3.Dense GABA\-BR2\|,GABA\-AR?2\| and GABA\-AR?\|LI fibers and terminals surround the somata of Vme neurons,especially for GABA\-AR?2\|LI.Conclusion\ The present results suggest that there are some differences in the distribution of the various subunits of GABA\-A\| and GABA\-B\|receptor in Vme.It is likely that the inhibitory regulation and control effects of GABAergic terminals on the transmission of orofacial region proprioceptive sensory information might be mainly mediated through GABA\-AR?1 and GABA\-AR?3 subunits in somata of Vme neurons.

Objective To observe the connections between the glutamic acid decarboxylase\|like immunoreactive(GAD\|LI) axonal terminals and the positive neurons showing phosphate actived glutaminase(PAG)\|LI or GABA\-A\|receptor ?3 subunit (GABA\-AR?3)\|LI and parvalbumin(PV)\|LI in the mesencephalic trigeminal nucleus(Vme) of the rat. Methods The triple\|immunofluoresence histochemical staining techniques were used in the present study,and stained sections were observed under a confocal laser\|scanning microscope. Results Many neuronal cell bodies through the whole rostrocaudal extent of Vme were showed dense GABA\-AR?3\|,PAG\| and PV\|like immunoreactivities,respectively.The majority of them were large pseudounipolar neurons(diameter 25\|50?m).About 90% of PAG\|LI neurons expressed both GABA\-AR?3\|LI and PV\|LI.Confocal laser\|scanning microscope further revealed that dense GAD\|LI axonal varicosities were found to surround the somata of Vme neurons showing both GABA\-AR?3\| and PAG\|like immunoreactivities,and formed the close contact each other.Conclusion\ The present results suggested that the GABAergic axonal terminals projecting to Vme might exert inhibitory regulation and control effect through GABA\-AR?3 subunit localizated in somata of Vme neurons on the transmission of orofacial region proprioceptive sensory information mediated by glutamate.

Epilepsy is a common nervous system seizure disease in children,20%-30% of them is intractable epilepsy.The pathogenesis of intractable epilepsy in children is not yet identify.Some research think that this may be associated with resistance of a variety of diffe-rent mechanisms of antiepileptic drug and abnormalities of multidrug resistance gene expression.The most investigation of multidrug transpor-ter is P-glycoprotein,multidrug resistance-associated protein.They are present in cell membrane and belong to adenosine triphosphate-dependent membrane transport protein.Studies have showed that over-expression of multidrug transporter in temporal lobe brain tissue of patients with refractory epilepsy and animal model of chronic epilepsy reduce the concentration of therapeutic drug in cells.They result in resis-tance by releasing the energy and transferring large amounts of anti-epileptic drugs to exterior of brain capillary endothelial cells in way of active transport.The relationship between multidrug transporter′s structure,distribution,functions and drug-resistant epilepsy are reviewed.

Objective To evaluate the clinical value of 99Tcm-MIBI scintigraphy for diagnosis of residual thyroid tissue and metastasis in patients with DTC after their first 131I therapy.Methods From February 2010 to March 2014,192 DTC patients (38 males,154 females,average age (43.2±8.6) years) who received total or near-total thyroidectomy and were pathologically diagnosed as DTC (171 papillary and 21 follicular carcinomas) underwent 99Tcm-MIBI scan (average dosage:740-925 MBq) 6 months after their first 131 I therapy.131 I scans was performed 4 d after oral administration of 131I of therapeutic dose (average dosage:5 550-8 140 MBq).Pre-and post-therapeutic images and the serum Tg level (detected before the imagings) were compared and analyzed.Any abnormal uptake of agent found inside or outside the thyroid was regarded as positive result.Patient-based and lesion-based data analysis were performed by x2 test and two-sample t test.Results A total of 191 patients were finally included,of which 65 positive cases were found.The sensitivity of 99Tcm-MIBI imaging was significantly lower than that of 131I imaging(56.9％ (37/ 65) vs 92.3％ (60/65);x2 =14.7,P＜0.01).Among 43 thyroid remnants and 22 metastatic lesions,99Tcm-MIBI imaging detected 39.5％ (17/43) of thyroid remnants and 90.9％ (20/22) of metastases,and those of 131I imaging were 100％ (43/43) and 77.3％ (17/22) respectively.The sensitivity of 131 I imaging in detecting thyroid remnants was significantly higher than that of 99Tcm-MIBI imaging(x2=24.0,P＜0.01).The sensitivities in detecting metastasis were not significantly different (x2=0.57,P＞0.05).The serum Tg level of positive groups (99Tcm-MIBI positive + 131I positive or 131I negative) were significantly higher than that of 99Tcm-MIBI negative + 131I negative group (t =-20.7 and-6.0,both P＜0.01),and that of 99Tcm-MIBI positive + 131I negative group was higher than that of 131I positive + 99Tcm-MIBI negative group(t=-2.7,P＜0.05).Conclusion 99Tcm-MIBI imaging could detect metastasis of DTC patient after first radioiodine therapy,but the value in detecting thyroid remnants is limited.
