Objective To investigate the relationship between the Vimentin expression and lymph node metastasis of cervical cancer in order to explore the possibility of its predictive value on the lymph node metastasis and parametrial infiltration. Methods The expression of Vimentin in cervical cancer tissue microarray chip which contains 78 cases was evaluated by immunohistochemistry method to study the relationship between the expression and lymph node metastasis and parametrial infiltration of cervical cancer. Results The expression of vimentin in 78 cases of cervical cancer tissue was 30/78 (38.5%) .The expression of vimentin in cervical cancer was significantly related to lymph node metastasis and parametrial infiltration respectively. The expression of Vimentin in lymph node metastasis positive group was 15/31 (48.4%), which were significantly higher than that in lymph node metastasis negative group. The expression of Vimentin in parametrial infiltration positive group was 17/32 (53.1%), which were significantly higher than that in parametrial infiltration negative group ( <0.05) . Conclusions The expression of vimentin in cervical cancer tissue is correlated with lymph node metastasis and parametrial infiltration. It is an effective way to predict the lymph node metastasis and parametrial infiltration in cervical cancer patients.

ObjectiveTo investigate the relationship between the serum concentration of IL-6,S100β,NT-3 and the cognitive functions in first-episode schizophrenia characterized by positive or negative symptoms.Methods44 first-episode schizophrenic patients characterized by positive symptoms (positive group),36 first-episode schizophrenic patients characterized by negative symptoms (negative group) and 50 healthy controls (controls) were collected.The serum levels of IL-6,S100β and NT-3 were measured by enzyme-linked immunosorbent assay (ELISA).The systematic evaluation tool-MCCB was applied to assess cognitive function in patients and controls.ResultsNT-3 serum levels in positive or negative groups were lower than those in controls and the differences were significant((118.39±37.50) ng/L,(112.55±32.29) ng/L vs (141.18±29.67) ng/L) (P<0.01).IL-6 and S100β serum levels in positive or negative groups were higher than those in controls and the differences were statistically significant((5.74±1.00)ng/L,(5.07±1.17)ng/L vs (4.23±0.91)ng/L),((132.98±46.71)ng/L,(124.99±43.14)ng/L vs (103.63±31.57)ng/L)(P<0.01).IL-6 serum levels in the positive group ((5.07±1.17)ng/L) were lower than those in the negative group ((5.74±0.99)ng/L) and the difference was statistically significant (P<0.05).In MCCB test,the TMT scores in patients characterize by positive symptoms or patients characterize by negative symptoms were higher than those in healthy control group (P<0.01).BACS SC,HVLT-R WMS-Ⅲ,SS,NAB,BVMT-R,CF in patients characterize by positive symptoms or by negative symptoms were lower than those in healthy control group(P<0.01).There were no statistical difference in the MCCB scores between the patients with positive symptoms and negative symptoms.In positive group,there was a positive correlation between the IL-6 serum concentration and the general symptom scores in PANSS (P<0.05).In positive group,NT-3 serum concentration was positively correlated with the general symptom scores or total scores of PANSS (P<0.05).BVMT-R scores in MCCB were also positively correlated with IL-6 or NT-3 serum concentration in positive group (P<0.05).ConclusionThe impairment of part of cognitive functions for schizophrenic patients may be related to the serum protein factors.There may be different in pathophysiology between the first-episode schizophrenic patients characterized by positive symptoms and those characterized by negative symptoms.
