RhoA, a small GTPase, is involved in a wide array of cellular functions in the central nervous system, such as cell motility, cytoskeleton rearrangement, transcriptional regulation, phagocytosis and cell growth. It is not known how spinal cord injury (SCI) affects the expression of RhoA in different nerve cells. In the present study, we investigated the changes of RhoA expression in remote areas of the injury at the 3rd, 7th and 30th day after SCI, which was established by T10 contusion method. Moreover, we examine its expression profile in neurons, astrocytes and microglia. RhoA was found to be weakly expressed in these nerve cells in normal spinal cord. Western blotting showed that, after SCI, the total RhoA expression was up-regulated, and the RhoA expression was increased and peaked at the 7th day. Double immunostaining revealed specific and temporal expression patterns of RhoA in different nerve cells. The expression of RhoA in neurons started to increase at day 3, peaked at day 7 and then decreased slightly at day 30. Expression of RhoA in astrocytes increased moderately after SCI and peaked at day 7. There was no obvious change in RhoA expression in microglia after SCI in remote areas. This study demonstrated that, after SCI, RhoA expression exhibited different patterns with different nerve cells of spinal cord. RhoA expression patterns also changed with time after SCI, and among different nerve cells in the injured spinal cord. These findings can help us better understand the roles of RhoA in SCI.

Methods:Clinic information of 110 LDH patients was selected according to settled criteria. Experiment group: 70 patients were treated by manipulation and Biqi Capsule. Control group: 40 patients were treated by manipulation and Fengshi Gutong Capsule. JOA and SAS 9.0 were used. Results: There were significant changes of JOA score before and after treatment in experiment group (t=20.68767,P

Objective:To evaluate the therapeutic effects of capsule of Biqi Capsule and VitB on lubar intervertebral disc protrusion(LIDP).Methods:78 Patients with LIDP were divided randomly into 2 groups:treatment and control group.39 Patients in treatment group were treated with Biqi Capsule and FENG's bone-setting manipulation,39 patients in control group were treated with vitamine B and FENG's bone-setting manipulation.All patients were followed up for 1 month after treatment for 2 weeks and therapeutic effects were evaluated.Results:In treatment group,24 patients were cured,6 patients had remarkable effects,5 effective,4 ineffective.In control group,the data were 16,8,8,7 correspondly.The therapeutic effects in treatment group were obviously better than those of control group(P

Objective To strengthen the quality control management and enhance the detection capacity of the experimental animal quality control laboratoriesin our country through the detection of serum esterase-1 (Es-1) in the experimental mice.Methods The samples were prepared according to the standard procedure, and then were randomly numbered and distributed to participating units by cold-chain transport.Before the deadline, the participants submitted the results and the copies of original records.When the results were completely consistent with the standard results,the results were regarded as satisfactory, otherwise were unsatisfactory.Results A total of 11 laboratories participated in this program, of which 10 laboratories were regarded as satisfactory (90.9%) and one laboratory obtained unsatisfactory result (9.1%).Conclusions The results of this proficiency testing project demonstrate that the overall detection level of Es-1 in laboratory mice is highof the participating laboratories.However, more attention still should be paid to standard specifications and some test details.

Objective To investigate the detection capacity of malic enzyme 1 and isocitrate dehydrogenase 1 ( Mod1&Idh1) in the laboratory animal monitoring laboratories in China in order to understand the detection capacity of la-boratories and to improve the detection level of laboratory animals’ quality.Methods Based on the program approved by CNAS, samples preparing, homogeneity test and stability test of malic enzyme 1 and isocitrate dehydrogenase 1 in the mouse kidneys were carried out.Standard operation procedure and samples with random numbers were distributed to the la-boratories.The laboratories should submit the result reports before the time limit expires.If the laboratory reports were the same with the standard results, the laboratories will receive satisfactory remark.If laboratory reports were not the same with the standard results, the laboratories will receive unsatisfactory remark.If a laboratory did not submit report, the laboratory will also receive unsatisfactory result.Results Eight laboratories out of 10 (80%) enrolled laboratories reported satisfac-tory experiment results, and two laboratories (20%) presented unsatisfactory results.Conclusions The whole detection level of laboratories in Mod1 &Idh1 is relatively high in the laboratory animals monitoring laboratories in China.It can re-flect the detection level of laboratories to conduct the laboratory capacity evaluation.

Objective To analyze the relationship between cervical lordosis and the development of dysphagia after anterior cervical spine surgery.Methods From June 2007 to May 2010,data of 172 successive patients who had undergone ACDF operation in our hospital were reviewed in this study.The presence and duration of postoperative dysphagia were recorded via face-to-face questioning or telephone interview at least one year after the procedure.Plain cervical radiographs before and after surgery were collected.The C2-7 angle was measured.The change of C2-7 angle was defined as dC2-7 angle=postoperative C2-7-preoperative C2-7 angle.The correlation between postoperative dysphagia and dC2-7 angle was studied.Results There were 22 patients in dysphagia group,including 17 males and 5 females.Their age ranged from 25 to 70 years old,and average was 47.7±5.4.The average of BMI was 25.0±2.9 kg/m2.150 patients were in non-dysphagia group,including 101 males and 49 females.Their age ranged from 18 to 72 years old,and average age was 49.2±4.8.The average of BMI was 24.4±3.4 kg/m2.There was no statistical difference in gender,age,and BMI between two groups.The dC2-7 angle of dysphagia group ranged from-1 °-20.5°,and average was 8.6°±4.0°.The dC2-7 angle of non-dysphagia group ranged from-13°-28.5°,and average was 5.0°±4.3°.There was significant difference in dC2 7 angle between dysphagia and non-dysphagia group.Spearman Analysis revealed that there was strong correlativity between dC2-7 angle and postoperative dysphagia.When dC2-7 angle was greater than 5°,the chance of developing postoperative dysphagia significantly increased (19.3％ [17/88] vs 6.0％ [5/84]).What's more,Spearman Analysis also revealed that there was no correlativity between dC2 7 angle and degree of operative dysphagia.There was no significant difference in gender,age,and BMI between dysphagia and non-dysphagia group.There was no statistical difference in operative time,blood loss revision surgery,revision surgery ratio,most cephalic operative level and number of operative levels between dysphagia with non-dysphagia group.Logistic regression model showed that an increased likelihood of postoperative dysphagia persists with increasing dC2-7 angle,but had no relationship with operative time,blood loss,revision surgery,most cephalic operative level and number of operative levels.Conclusion dC2-7 angle may play an important role in the development of postoperative dysphagia.We found no statistical difference in operative time,blood loss revision surgery,revision surgery ratio,most cephalic operative level and number of operative levels between dysphagia and non-dysphagia group.Intraoperative measurement of the dC2-7 angle is practical and essential for reducing the postoperative dysphagia.
