Objective To investigate the effects of survivin antisense oligonucleotide (ASODN) on human uterine endometrial cancer HEC-1B cell line. Methods The experiment included four groups: blank control group (blank), lipofectin control group (Lip), oligonucleotide (SODN) control group and antisense oligonucleotide (ASODN) test group. Artificially synthesized survivin antisense oligonucleotide was transfected for 48 hours into endometrial cancer cells using liposome after cultivation. The expression of survivin protein was determined by Western blot, and the cellular apoptotic rate was tested by flow cytometric analysis. MTT method was used to assay cellular growth rate. Results In comparing with the blank, Lip and SODN control groups, survivin protein expression was obviously decreased in HEC-1B cancer cells after transfected with survivin ASODN. The apoptotic rate and proliferation inhibition rate in ASODN test group were significantly higher than that in the control groups (P<0.05). There was no significant difference between other control groups (P>0.05). Conclusions The expression of survivin is decreased in endometrial cancer cells after ASODN transfection. Survivin ASODN causes cellular apoptosis and inhibits the proliferation of HEC-1B cells. It may be a useful gene therapy for endometrial cancer.

Objective:This study aimed to investigate the associations between single-nucleotide polymorphism (SNP) of IGF-1 and IGFBP-3 gene and risk of non-smoking female lung cancer in Chinese population. Methods:Genotyping was performed using the TaqMan method in 287 histologically confirmed non-smoking female lung cancer cases and 281 healthy controls. Results:The geno-type distributions of IGF-1 polymorphisms were significantly different between cases and controls (P<0.001). Analysis of multivariate logistic regression showed that the carriers of the CC genotype exhibited a significantly decreased risk of lung cancer in non-smoking female (adjusted OR=0.28, 95%CI:0.15-0.54). IGF-1 rs1520220 GG genotype may reduce the risk of advanced lung cancer incidence in nonsmoking female (adjusted OR=0.30, 95%CI:0.09-0.96). Log-rank test and Cox regression analyses revealed that variant geno-types of IGF-1 rs2946834 CT/TT had a significantly decreased lung cancer mortality risk compared with the homozygote CC in≥60 age group or patients with a lung tumor>3 cm. Conclusion:The IGF-1 polymorphism was associated with the risk of lung cancer and prognosis among non-smoking female. More rigorous laboratory studies of large sample population and functional studies are warrant-ed to confirm our findings.

Objective To evaluate a new model of anterior spinal cord injury (SCI) syndrome and to explore the pathophysiology of SCI. Methods Fifty-five Wistar rats were randomly divided into a sham-operated group ( 10 rats) and an experimental group (45 rats). A metal hook was fixed in front of the rats'abdomens to compress the ventral part of the spinal cord in the experimental group. According to the degree and time of compression,the rats in the experimental group were divided into light, moderate, heavy injury subgroups. The tilt board test and the Bosso-Beattie- Bresnahan (BBB) locomotor rating scale were used to assess the rats' behavior at the 1st , 7th andl4th days and after 4 and 8 weeks. The latency of somatosensory evoked potential (SEP) and motor evoked potential (MEP) were measured before and 8 weeks after the operation. Results After the operation the gradients in the tilt board test and BBB scores in the experimental subgroups were all significantly lower than in the sham-operated group. There were also significant differences among the 3 severity subgroups. Eight weeks after the operation the average MEP latencies in the experimental subgroups were significantly longer than in the sham-operated group, and there were also significant differences among the 3 severity sub-groups. MEP in the heavy injury subgroup was significantly longer compared with the sham-operated group. Conclusions Obvious behavioral and neuroelectrophysiological changes were observed in the injured rats. Models of different severity could be prepared and reproduced to simulate clinical SCI.
