Objective To acquire some related data of surgical approach through brain superior temporal sulcus to temporal horn of lateral ventricle by MRI volume rendering, and to orientate the point of superior temporal sulcus on the lateral surface which is closest to temporal horn of lateral ventricle,and to find out the best entrance point of surgical approach through superior temporal sulcus to temporal horn of lateral ventricle.Methods 120 adult cases of MRI scanning specimens were chosen for measurement. MRI volume rendering technology was used to rebuild the brain 3D model for the measurement of the full length of superior temporal sulcus S1 .Then cutting along the prependicular to the direction of the long axis of the temporal lobe with 1.0 mm spacings,the coronal sections were obtained,and the distance from superior temporal sulcus to temporal horn of lateral ventricle was ordinally measured and the shortest distance S2 was made sure.And the depth of superior temporal sulcus S3 was detected. The corresponding point on the surface of the brain at superior temporal sulcus according to the point leading the shortest distance S4 was determined. The ratio of S4 to S1 M was calculated. The angle between the shortest distance and median sagittal plane asαwas determined.All the samples were measured on both sides of the brain and all the data were compared.Results The S1 of the 120 cases was (159.56 ± 17.55)mm on the left and (164.35± 15.07)mm on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);the S2 was (8.18±0.96)mm on the left and (7.81±0.90)mm on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);the S3 was (12.19±1.43)mm on the left and (11.57± 1.33)mm on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);the S4 was (100.88±16.09)mm on the left and (104.15±14.49)mm on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);the M was (0.63 ±0.07)on the left and (0.63 ±0.06)on the right,there was no statistical difference between two cerebral hemispheres(P>0.05);theαwas (55.80±3.64)°on the left and (56.46±4.17)°on the right,there was no statistical difference between two cerebral hemispheres(P>0.05). Conclusion The point at the front side 3/5 of superior temporal sulcus may be the ideal surgical approach entrance point.The distance from the point to temporal horn of lateral ventricle is shortest.It indicates that the approach can reduce the damage of brain tissue.

Objective To investigate the difference of Alzheimer-associated neuronal thread protein ( AD7c-NTP) level and related factors among different symptom types of schizophrenia. Methods The con-centrations of AD7c-NTP in urine of 30 patients with positive symptoms,46 patients with negative symptoms and 24 controls were detected by enzyme linked immunosorbent assay( ELISA) . Positive and negative symp-tom scale ( PANSS) was used to assess schizophrenia patients. The correlation analysis was conducted be-tween the urine AD7c-NTP and demographic factors. Results The level of AD7c-NTP in urine of patients with negative symptoms((0. 88±0. 93) ng /ml)was higher than that in the patients with positive symptoms ((0. 50±0. 22)ng/ml,P<0. 05). The level of AD7c-NTP of in urine female patients((1. 16±1. 12)ng/ml) was higher than that in the male patients((0. 57± 0. 49)ng/ml,P<0. 01). AD7c-NTP levels in patients with a course of disease of more than 100 months((0. 96±0. 96)ng/ml) were higher than those in patients with a course of disease of less than 100 months((0. 60±0. 59)ng/ml,P<0. 05). The level of AD7c-NTP in pa-tients over 35 years old((0. 94±0. 96)ng/ml) were higher than that in patients under 35 years old((0. 62±0. 62)ng/ml,P<0. 05). The level of AD7c-NTP in patients with MMSE score of 0-22 points((0. 92±0. 80) ng/ml) were higher than that in patients with score of 23-29 points((0. 62±0. 74)ng/ml,P<0. 05). Before admission(at least 2 months),the level of AD7c-NTP in patients without persisting in taking drugs((0. 99± 0.95)ng/ml) was higher than that in patients with persisting in taking drugs((0. 62±0. 65)ng/ml,P<0. 05). The level of AD7c-NTP in schizophrenic patients was positively correlated with age and course of dis-ease( r=0. 29,0. 26,P<0. 05) ,and negatively correlated with smoking history and mini-mental state exami-nation( MMSE) ( r=-0. 13,-2. 41,P<0. 05) . Conclusion There is a difference in AD7c-NTP levels be-tween patients with positive and negative symptoms of schizophrenia. Gender,age,course of disease and anti-psychotics are important factors that affect AD7c-NTP levels in patients with schizophrenia.

Extracorporeal membrane oxygenation(ECMO) is a type of technique which can be used to replace patients' pulmonary function and cardiac function effectively. Since 2000s,the technique began to apply in pediatric patients but still developed very slowly. As well,patients transport with ECMO is another problem for the pediatricians. So,it is necessary to raise the conception of pediatric ECMO transport network and construction of the network. In this paper,the concept of pediatric ECMO transport network,current status of transport,the characteristics and constitution of pediatric ECMO transport network,indication for transport of pediatric ECMO,the problems in the construction of network were introduced to promote the construction of the network.
