Objective To investigate the expression levels and clinical significance of (forkhead box Q1) FOXQ1 and E-cadherin in esophageal squamous cell carcinoma (ESCC). Methods Expression levels of FOXQ1 and E-cadherin were in ESCC tissues (ESCC group, n=42) and adjacent normal esophageal tissues (control group, n=42) were detected using im?munohistochemistry. Correlations of FOXQ1 and E-cadherin expressions with clinical pathological parameters and progno?sis were analyzed between two groups. Results The expression level of FOXQ1 was significantly higher in ESCC group than that in control group(64.29% vs 28.57%,χ2=5.384,P<0.05). The expression level of E-cadherin was significantly lower in ESCC group than that incontrol group(52.38%vs 90.48%,χ2=7.691,P<0.05). There were significant differences in FOXQ1 expressions between different TNM stages and whether lymph node metastasis is involved within ESCC group. There were significant differences in expression of E-cadherin between different tumor differentiation, depth of invasion, TNM stage and whether lymph node metastasis is involved within ESCC group. The expression of FOXQ1 was negatively cor?related with E-cadherin in ESCC (r=-0.412, P<0.05). The 5-year survival rates were significantly lower with high expres?sion of FOXQ1 or with low expression of FOXQ1(18.52%vs 66.67%,χ2=9.737,P<0.05). The 5-year survival rates were significantly higher with high expression of E-cadherinor low expression of E-cadherin(59.09%vs 10.00%,χ2=10.996,P<0.05). A multivariate Cox's proportional hazard regression analysis indicated that high FOXQ1 expression, low E-cadherin expression and lymph node metastasis were independent prognostic factors for ESCC. Conclusion The expression of FOXQ1 and E-cadherin showed a good correlation with ESCC. And examining expressions of both FOXQ1 and E-cadherin in ESCC may have practical values in estimating the prognosis of ESCC and directing future treatment .

ObjectiveTo investigate the characteristics of event-related potential (ERP) N270 and the value of ERP N270 to detect the cognitive function in patients with epilepsy.MethodsThirty-five epileptics were divided into carbamazepine (CBZ) group (n=10), valproate (VPA) group (n=10) and no treatment group (n=15) according to drugs they took, and other 10 healthy subjects were selected as the control group. All subjects were evaluated by Mini-Mental State Examination (MMSE), and ERP was recorded at same time.ResultsAll patients in three groups showed a delayed and smaller N270 than the control group ( P<0.01). VPA group had the lowest N270 amplitude. The amplitude of P300 elicited in the match condition decreased in the VPA group compared with other three groups ( P<0.05), but latency of the VPA group was not different from other three groups.ConclusionCognitive impairment is present in epilepsy patients, and the effect of anti-epileptic drug VPA on ability of patients to process conflict is more evidence than CBZ. The sensitivity of N270 to detect early cognitive impairment in epileptics is higher than P300.

Objective To study the effect of spontaneous subarachnoid hemorrhage (SAH)on transient receptor potential melastatin 4 (TRPM4)channel activity. Methods Seventeen SD rats of clean grade were selected. They were randomly divided into either a SAH (n = 10)or a sham operation group (n = 7) according to the random number table. At day 5 after SAH modeling,the cerebral arteries were harvested and the cerebral arterial smooth muscle cells were isolated using enzymatic digestion method. Western blot was used to detect TRPM4 expression and translocation rate. Patch-clamp techniques were used to study the maximum current intensity of the TRPM4 single channel in cerebral arterial smooth muscle cells. Results The fluorescent-stained TRPM4 were observed in cerebral arterial smooth muscle cells in the 2 groups of rats. The relative quantities of TRPM4 in the total protein of the sham operation group and the SAH group were 24 ± 3% and 32 ± 4% respectively. There was significant difference between the 2 groups (t = 4. 47,P < 0. 01). The translocation rates of TRPM4 in the sham operation group and the SAH group were 44. 0 ± 1. 9% and 60. 1 ± 2. 3% respectively,and the SAH group was higher than the sham operation group (χ2 = 4. 48,P < 0. 05). When the clamping voltages were - 100 mV,- 80 mV,- 60 mV,and - 40 mV,the maximum current intensity of TRPM4 single channel of the sham operation group was more than that of the SAH group. There were significant differences between the 2 groups (- 1. 90 ± 0. 10 mV vs. - 2. 23 ± 0. 08 mV,- 1. 68 ± 0. 12 mV vs. - 1. 99 ± 0. 12 mV,- 0. 89 ± 0. 09 mV vs. - 1. 24 ± 0. 09 mV,and - 0. 69 ± 0. 12 mV vs. - 0. 92 ± 0. 11 mV;all P < 0. 01). When the clamping voltages were - 20,0,20,40,60,80,and 100 mV,there was no significant difference in the maximum current intensity of TRPM4 single channel between the 2 groups (all P > 0. 05). Conclusion SAH has the induced effect for TRPM4 activity.
