Objective To study interleukin-1 receptor(IL-1R) and connexin(Cx36) gene expression following Mg 2+-free-induced seizures in cultured developing neuron. Methods Rat embryo cortical neurons cultured for 6 and 17 days were exposed to Mg 2+-free media to induce seizure. At different time after Mg 2+-free treatment, real-time RT-PCR was used to detect IL-1R and Cx36 mRNA expression. Results 1. IL-1R mRNA expression transiently decreased after Mg 2+-free treatment in neurons cultured for 6 and 17 days in vitro. Then the levels of IL-1R mRNA expression recovered in neurons cultured for 6 days, but IL-1R mRNA expression were increased in neurons cultured for 17 days compared with control group and the peak was at 24 hours. 2. In neurons cultured for 6 days in vitro, Cx36 mRNA expression increased after Mg 2+-free treatment compared with control group, the peak was at 24 hours. But in neurons cultured for 17 days in vitro, Cx36 mRNA expression decreased at 6 hours after Mg 2+-free treatment compared with control group, the peak was at 24 hours. Conclusions IL-1R mRNA and Cx36 mRNA expression following Mg 2+-free-induced seizures are different between the neurons cultured for 6 and 17 days in vitro. This is possibly related to the different neuron injury between 6 and 17 days in vitro following seizures.

AlM:To investigate the expression of VEGF, CD34, Ki-67 and p21 in pterygium as well as the correlation between their expression and clinical pathological characteristics;explore its pathogenesis.
METHODS: lmmunohistochemical S - P staining method was adopted in detecting the expression of VEGF, CD34, Ki-67 and p21 in 62 cases of pterygia and 20 cases of normal conjunctival tissues. Relationship between these markers and clinical pathological characteristics was analyzed.
RESULTS:(1) The positive expression of VEGF, CD34, Ki-67 and p21 in 62 cases of pterygia was 74. 2% (46/62), 77. 4% ( 48/62 ), 66. 1% ( 41/62 ) and 40. 3% ( 25/62 ) respectively. The differences were statistically significant compared with normal conjunctival tissues (P<0. 05). (2) The expression of VEGF and CD34 in 62 cases of pterygia was correlated with clinical types and stages (P<0. 05), and was not associated with sex, age and occupation ( P>0. 05 ); the expression of Ki-67 was correlated with clinical stages (P<0. 05), and was not associated with other clinical pathological characteristics ( P>0. 05 ); the expression of p21 was correlated with clinical stages and pterygium characters (P<0. 05), and was not associated with other clinical pathological characteristics ( P> 0. 05 ). ( 3 ) Spearman correlation showed that there was a positive correlation between VEGF and Ki - 67 ( r = 0. 279, P < 0. 05 ), a positive correlation between VEGF and CD34 (r=0. 299, P<0. 05), a negative correlation between VEGF and p21 (r=-0. 267, P<0. 05 ); it also showed that there was no correlation between any two of CD34, Ki-67 and p21 (P>0. 05).
CONCLUSlON: ( 1 ) Overexpression of VEGF, Ki-67, CD34 and low expression of p21 suggest that these markers are concerned with the development and progression of pterygium. ( 2 ) Expression of VEGF and CD34 increases along with the increase of clinical types and stages, expression of Ki-67 increases along with the increase of clinical stages, and expression of p21 decreases along with the improvement of clinical types or stages; they suggest that these markers may play important roles in the development and recurrence of pterygium. ( 3 ) There is positive correlation between VEGF and Ki-67, VEGF and CD34 as well as negative correlation between VEGF and p21. They suggest that there may be synergistic action between two factors during the development and progression of pterygium.

OBJECTIVETo study the diagnostic value of diffusion tensor imaging (DTI) in cervical spondylotic myelopathy.
METHODSTwenty healthy volunteers and fifty patients with cervical spondylotic myelopathy underwent DTI in the Affiliated Hospital of Medical College of Ningbo University from January 2014 to April 2015. Healthy volunteers served as controls. Fifty patients were divided into three groups (group A , B, C) according to cervical MRI scan standard. Group A (17 cases) had only the dura mater spinalis compressed; Group B (23 cases) showed the cervical spinal cord compressed, but no high signal in it; Group C (10 cases) had the cervical spinal cord compressed with high signal in the same level. The average apparent diffusion coefficients(ADC) and fractional anisotropy (FA)values in these examinee were analyzed and all subjects were performed fiber tracking.
RESULTSThere was no statistically significant differences in ADC and FA values in C2/C3, C3/C4, C4/C5, C5/C6, C6/C7 of control group (P>0.05). The average ADC and FA values in control group were (0.875 +/- 0.096) x10(3) mm2/s and 0.720 +/- 0.051, respectively; compared with group A,there was no statistically significant difference; compared with group B and C, there was significant difference; comparison among group A, B, C, there was significant differences.
CONCLUSIONDTI can early and accurately quantify the changes of microstructure in cervical spondylotic myelopathy. Fiber tracking can show the damage range of spinal cord lesions.

OBJECTIVETo explore the therapeutic effect and mechanism of Aitongping capsule (ATP) in treating cancerous pain.
METHODSSixty cancer patients were randomly divided into two groups, 30 patients in the treated group took ATP and 30 patients in the control group took diclofenac, 1 week of treatment was applied. The relevant clinical conditions of cancerous pain, the content of plasma beta-endorphin (beta-EP) and c-AMP, hemorheological index, improuement of life quality of patients, occurrence rate of adverse reaction were observed before and after treatment.
RESULTSThe total effective rate in the treated group and in the control group was 90.0 % and 83.3%, respectively, difference between them showed no significance. However, there were significant difference between the two groups in such aspects as the degree of pain relieving, the decrease of pain episodes, the shortening persistent time of pain and the initiation time of analgesic action and prolonged analgesic duration, the decrease of tenderness and percussion pain, the increase of plasma beta-EP content and the decrease of cAMP (P< 0.05 or P< 0.01). The evidences also showed that it was better in improving quality of life, ameliorating hemorheologic indexes and reducing incidence of adverse reaction in the treated group than in the control group (P <0.05 or P <0.01).
CONCLUSIONATP has affirmative effect on cancerous pain, its analgesic effect may be associated with the increasing of plasma beta-EP content, decreasing of cAMP level and ameliorating of hemorheologic indexes.
