As an important component of the event related potential (ERP), late positive potential (LPP) is an ideal component for studying emotion regulation. This study was focused on processing and analysing the LPP component of the emotional cognitive reappraisal electroencephalogram (EEG) signal. Firstly, we used independent component analysis (ICA) algorithm to remove electrooculogram, electromyogram and some other artifacts based on 16 subjects' EEG data by using EGI 64-channal EEG acquisition system. Secondly, we processed feature extraction of the EEG signal at Pz electrode by using one versus the rest common spatial patterns (OVR-CSP) algorithm. Finally, the extracted LPP component was analysed both in time domain and spatial domain. The results indicated that (1) From the perspective of amplitude comparison, the LPP amplitude, which was induced by cognitive reappraisal, was much higher than the amplitude under the condition of watching neural stimuli, but lower than the amplitude under condition of watching negative stimuli; (2) from the perspective of time process, the difference between cognitive reappraisal and watching after processing with OVR-CSP algorithm was in the process of range between 0.3 s and 1.5 s; but the difference between cognitive reappraisal and watching after processing with averaging method was during the process between 0.3 s and 1.25 s. The results suggested that OVR-CSP algorithm could not only accurately extract the LPP component with fewer trials compared with averaging method so that it provided a better method for the follow-up study of cognitive reappraisal strategy, but also provide neurophysiological basis for cognitive reappraisal in emotional regulation.

Objective To investigate the value of soluble epithelial cadherin(sE-cad)in the differential diagnosis of pleural effusion. Methods Patients were divided into malignant pleural effusion group,infective pleural effusion group and transudation group.sE-cad in pleural fluids obtained during the first thoracocentesis was measured by enzyme-linked immunosorbent assay(ELISA).The concentration of sE-cad in all kinds of pleural effusions was compared.The cut-off value of sE-cad for the differential diagnosis of benign and malignant pleural effusion was determined by ROC curve.The diagnostic value of sE-cad was also compared with common tumor markers such as CEA,CA199,CA125 and NSE.Results The concentration of sE-cad was significant higher in the malignant pleural effusion than in the benign pleural effusion[(38.38?4.15)ng/mL vs(14.17?0.80)ng/mL,P

OBJECTIVE:
To analyze the results of hearing screening and the related factors in 3200 newborn infants, in order to know the incidence of neonatal hearing disorders.
METHOD:
Three thousand two hundred cases of newborn infants born during 2014-01 and 2015-03 were tested for hearing screening. According to risk factors, newborns were divided into the normal newborn group (2945 cases) and the high-risk neonatal group (255 cases). Using fast brainstem auditory evoked potential (AABR) to screen the hearing screening of newborn infants with 3~5 d; those who did not pass the screening, after the birth of 30~42 d re-screening; re-screening still not pass, within 3 months line diagnostic auditory brainstem evoked potential (diagnostic ABR) confirmed. Comparative analysis of newborn hearing screening by screening through rate, re-screening through rate and hearing impairment rate proportional relationship with the relevant factors, and the differences of hearing screening results in the normal newborn group and the high-risk neonatal group.
RESULT:
(1)The rate of neonatal hearing screening did not pass was 7.50% (240/3,200); 30 cases was not involved in re-screening, the rate of re-screening did not pass was 15.24% (32/210); hearing impairment rate is about 0.38%(12/3200), and the bearing impairment positive rate was 1.31% (42/3200). (2) There was no significant difference of different delivery mode, neonatal sex in newborn hearing screening through rate, re-screening through rate and hearing impairment rate (P > 0.05). Different gestational age, maternal age in newborn hearing screening through rate, re-screening through rate and hearing impairment rate, the difference was statistically significant (P < 0.05). (3) Screening through rate and re-screening through rate of the high-risk neonatal screening group were significantly lower than the normal newborn group (P < 0.05), and hearing impairment rate was higher than normal newborn group (P < 0.05).
CONCLUSION
Strengthen prenatal health care, to reduce abnormal childbirth conditions (preterm birth, neonatal asphyxia), universal newborn hearing screening and improve screening accuracy, and to strengthen newborns with risk factors for early diagnosis and intervention, to reduce the incidence of neonatal hearing impairment has important significance.

AIM: To detect the differentiation effects of retinal cells or extracts on bone marrow-derived mesenchymal stem cells (BMSC).METHODS: Human fetal BMSC were previously labeled by carboxyfluorescein succinimidyl ester (CFSE), and co-cultured with retinal pigment epithelial (RPE) cells which were pre-treated with ultraviolet irradiation at a ratio of 1∶1 to induce the differentiation of BMSC for up to 14 days. In some assays, a retinal extract of bovine retinal extract (BRE) was added to detect the potential effects of retinal component on the differentiation of BMSC. In addition, neuron-specific enolase (NSE), Nestin and Glial fibrillary acidic protein (GFAP) immunostaining were performed to determine the characteristics of BMSC.RESULTS: The results indicated that by co-cultured with RPE cells, fetal BMSC were differentiated into neural-like cells expressing special neuronal markers Nestin, GFAP and NSE. And the expression of these markers was obviously increased by BRE.CONCLUSION: Retina derived cells and extracts can induce the differentiation of BMSC into neural-like cells.

Background Human retinal pigment epithelial (RPE) cell transplantation treating retinal degenerative diseases is a researching topic,and the source of human RPE cells is a key problem.Many biological carriers can be used for the preparation of RPE cell layer.However,some advantages,such as cytotoxicity,lack of stability and immunologic reaction etc.are still existed.To study an ideal biological carrier is very important.Objective This experimental was to determine the effects of amniotic membrane on the proliferation and differentiation of human RPE cells and the possibility as a scaffold for RPE cell transplantation.Methods ARPE19 cell line cells were cultured and passaged in DMEM/F12 medium with 10% fetal bovine serum,and 8-12generation of cells were used.The cells were divided into two groups.One group of cells were incubated on the denuded amniotic membrane,and the other group of cells were cultured in the medium (control group).MTT was performed to detect the A492 value of RPE cells for the evaluation of cell proliferation ability 24,48,72,96 hours after culture.Cell morphology was compared by histopathological examination 3 weeks after culture.The mRNA expression of pigment epithelium-derived factor (PEDF),N-cadherin,β-catenin and cell connection related proteins in the cells of both groups were assayed using reverse transcription polymerase chain reaction (RT-PCR).Ultrastructure of the cells was observed under the transmission and scan electronic microscope 3 weeks after culture.Results The number of ARPE-19 cells cultured on denuded amniotic membrane was decreased significantly in comparison with the normal culture plate(F=41.760,P =0.000).Histopatholy also showed that the cell density on amniotic membrane was lower than of normal cells on plate surface.Moreover,the expression level of claudin 1 mRNA,N-cadherin mRNA and PEDF mRNA were significantly up-regulated in denuded amniotic membrane group in comparison with control group (t=15.828,P=0.000 ;t=6.839,P=0.002 ;t=14.667,P=0.000),but the expression of Connexin 43 mRNA was down-regulated in denuded amniotic membrane group compared with control group(t=3.358,P=0.024).Ultrastructural examination revealed that ARPE-19 cells cultured on amniotic membrane exhibited a polygonal epithelial phenotype with cilium on the apical side,however,the cells cultured on normal culture plate displayed fusiform shape and uneven thickness.Conclusions Amniotic membrane plays a promoting effect on the differentiation of ARPE-19 cells and a inhibitory effect on the proliferation of ARPE-19 cells,suggesting that amniotic membrane might be an useful scaffold for the preparation of functionally mature RPE cells for clinical transplantation.
