To determine the content of 10-Hydroxy -2-decenoic acid in Chongcaojing Wangjiang Capsule by HPLC.The column was Discovery C 18 .The detective wavelength was at 209 nm. The mobile phase was acetonitrile: 0.5% phosphoric acid (25∶75) with the flow rate being 1.0 mL/min and the column temperature at 25℃.There was a good linearity (r=1) winthin the range of 0.02144 ～ 0.38592 ?g. The average recovery rate was 101.8%, RSD= 1.6%. [Conclusion] This method can be used for the quality control standard of Chongcaojing Wangjiang Capsule.

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.

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:Comparative study on clinical manifestation of the lumbar disc herniation(LDH) patients with Japanese Orthopedic Association Scale (JOA) before and after treated by massage with Chinese medicine. 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 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.
