OBJECTIVETo explore the value of the application of oil red O staining in spinal cord injury (SCI) of rats.
METHODSWith simple randomization, 24 Spargue-Dawley male rats were divided into normal control group including 6, and SCI group including 18. Spinal cord was transected at spinal lever T10 to build SCI model. Six rats of SCI group were sacrificed randomly at 1, 2, 4 weeks after surgery. After the spinal cord tissue sections were made, oil red O staining methods were used to observe the changes at the end of transected spinal cord. Images were analyzed by Image-Pro Plus 6.0 and SPSS 20.0 software.
RESULTSThe oil red O staining of normal control group showed that white matter surrounded by myelin sheath was clear and obviously distinctive from grey matter. Uneven and strengthened staining in oil O was observed in grey matter of SCI group at 1, 2, 4 weeks post-SCI.
CONCLUSIONIt is a good method to label the myelin sheath in spinal cord and distinct white matter from grey matter by oil red O staining. Analysis of the images showed that lipid may become another target for drugs, which needs more researches.

Objective To investigate the emotional memory characteristic in patients with leuloaraiosis(LA) and explore the neurobiological mechanisms through observing the changes of emotional memory.Methods Different valence images (including positive,neutral and negative pictures) were used to test twenty-four patients with Leuloaraiosis(LA group)and twenty-four healthy colltrols(HC group) at the same time.The emotional memory was evaluated by the recognition of emotional pictures.Results In appraisal of the emotional pictures,there was no significant difference between patients with LA (positive (10.42±2.30) and neulral (12.87±2.29),respectively) and healthy controls (positive (11.38 ± 3.25) and neutral (12.75 ± 2.86),respectively) in positive and negative appraisal (all P>0.05).But the negative appraisal decreased between LA group (11.63 ± 1.81) and HC group (12.75 ± 2.02) (P> 0.05).Compared with healthy controls (38.08+±5.45),patients with LA(33.67±7.10) showed sharply decline in the emotional images memorizing task(P<0.05).And the accuracy in recognizing positive and netural valence pictures in patients with LA ((Positive(11.04±2.40) and neulral (10.42±2.93)) was significantly lower than that in healthy controls ((positive(12.79±2.17) and neutral(12.08±2.59))(P<0.05).But in negative stimulus,there was no significant difference between LA group(13.20± 1.86)and HC group(12.20±2.65) (P>0.05).In addition the total correct recognition,positive and neutral valence in pictures recognition were negativly correlated with the se verity of white matter lesions in the LA patients group(r=-0.308,P=0.033;r=-0.462,P=0.003;r=-0.352,P=0.014).Conclusion The emotional memory is impaired in patients with LA,and the degree of damage is accompornied with the severity degree of LA.The emotional memory for positive and neutral vanlence pictures is impaired but the emotional memory for neutral is relatively reserved in patients with LA in pictures recognition phase.It suggests that impaired emotional memory with different valences may be related to different neuromechanisms.

ObjectiveTo investigate the dynamic expression of Mindin protein in mice with acute liver injury induced by carbon tetrachloride (CCl4) and its mechanism of action. MethodsA total of 48 male C57B1/6 mice were selected and divided into experimental group (n=40) and control group (n=8). The mice in the experimental group were given intraperitoneal injection of CCl4 olive oil to induce acute liver injury, and the liver tissue was collected for pathological observation at 6, 12, 24, 48, and 72 hours after modeling. The mice in the control group were given intraperitoneal injection of olive oil. Western blot was used to measure the protein expression of Mindin and its change trend, and quantitative real-time PCR was used to measure the mRNA expression of Mindin. The t-test was used for comparison of continuous data between two groups. ResultsAbnormal liver structure was observed after liver injury was induced by CCl4, with the most significant pathological change at 48 hours. There was a low protein expression level of Mindin within 12-72 hours after the injection of CCl4. The mRNA expression of Mindin reached the lowest level at 12 hours after CCl4 injection and there was a significant difference between the experimental group and the control group at this time point (0.183±0.105 vs 1.023±0.247, t=8.841, P<0.01); then there was a gradual increase in the mRNA expression of Mindin, and at 48 and 72 hours, the mRNA expression of Mindin in the experimental group was more than 2 times that in the control group (48 hours: 2.548±0.775 vs 1.023±0.247, t=5.428, P<0.01; 72 hours: 2.699±0995 vs 1.023±0.247, t=4.621, P<0.01). ConclusionThere is a significant change in Mindin protein during the process of acute liver injury induced by CCl4 in mice, which is characterized by the downregulation of protein expression and the regulation of post-transcriptional mRNA level, suggesting that Mindin may play an important role in the process of acute liver injury induced by CCl4.

Objective To investigate the efficacy of twice irradiating with focused ultrasound on recurrent and metastasized U14 cervical cancer implanted in the legs of mice. Methods Seventy-two mice with U14 cervical cancer cells implanted in their legs were divided into three groups randomly,with 24 rats in each group.One group received a single dose of focused ultrasound,while mice in the second group were irradiated twice and surgery resection was administered to the third group 7 or 8 days after the tumor was implanted.After 23 days post implantation of the tumor,local tumor recurrence and metastasis to the lungs and lymph nodes were evaluated. Results The inhibition rate after double irradiation was 61.70% for local recurrence and 68.18% for metastasis,significantly higher than in the other two groups. Conclusions Both single and double irradiation with focused ultrasound are effective for inhibiting local recurrence and metastasis,but double irradiation is more effective.
