BACKGROUND: Nerve fiber degeneration and horseradish peroxidase antrograde tracing methods are commonly used to study nerve pathway. However, both the methods cannot mark the area clearly and lack of sensitivity so that they cannot fully present the projection area of nerve fibers. It needs further efforts on developing new nerve pathway tracing methods to effectively research nerve pathway.OBJECTIVE: To look for a highly sensitive method of nerve pathway tracing in order to provide a simple, objective and reliable method to study regeneration.DESIGN: A randomized and controlled trial based on experimental animals.SETTING: Department of Internal Medicine of a hospital and the Experiment technique teaching section of a university.MATERIALS: The experiment was completed in the Experiment Technique Teaching Section of Chengdu Medical College. Six healthy male SD rats provided by Experimental Animal Centre of West China Medical University were used.METHODS: Using CB-HRP as tracer while using sodium tungstate as stabilizer of TMP to antrograde tracing the projection of optic nerve fibers on anterior region of hypothalamus and retrograde tracing the distribution of hypoglossal nerve fibers on the dorsal side of medulla.MAIN OUTCOME MEASURES: Distribution and dyeing of neuron bodies and nerve fibers.RESULTS: The fibers of optic nerve projected to the dorsomedial side of suprachiasmatic nucleus and the fibers of hypoglossal nerve projected on the hypoglossal nucleus on dorsomedial portion of the medulla oblongate. The result shows that the neurons and axons are very clear.CONCLUSION: It is a highly sensitive method to trace nerve pathway by using CB-HRP as tracer and sodium tungstate as stabilizer of TMB.

Objective To explore the dignostic value of the candidate molecular markers in Urothelium carcinoma based on Illumina Transcriptome Sequencing. Methods Candidate genes which were screened with transcriptome sequencing were validated by using real-time fluorescent quantitative PCR in 31 pairs of tumor and normal tissues of Urothelium carcinoma patients from Affliated Hai kou Hospital Xiangya School of Medicine Central South University. Results The four candidate genes (CDH1,VEGFA,PTPRF and CLDN7) in tumor tissues were up-regulated compared with normal groups in samples of sequencing. The relative expression of VEGFA mRNA were higher than that in normal tissues. There were significant difference in two groups (P<0.05). PTPRF and CLDN7 were also up-regulated, but no significant difference was found (P > 0.05). PTPRF was closely related with the recurrence of tumor (P=0.002), and the predict sensitivity and speciality rate were 90.0%and 83.3%respectively. Conclusions CDH1 and VEGFA play important roles in the occurrence and development of bladder urothelial carcinoma, and they may be the possible biomarkers. PTPRF is expected to be a molecular reference recurrent predictor of bladder tumor.

Objective To investigate the effect of Danzhijiangtang capsule on serum,fat in type 2 diabetic rats.Methods The model of type 2 diabetes mellitus rats were established by injecting small does streptozotocin(STZ)into abdomen and feeding high sucrose-fat diet.All the rats were divided randomly into five groups.The level of blood glucose,serum insulin,insulin sensitivity index,blood fat(triglyceride, cholesterol,high-density lipoprotein,low-density lipoprotein),free fatty acid after treated were examined. Results Danzhijiangtang capsule could decrease the level of blood fat.Conclusion Danzhijiangtang capsule could improve the blood fat in type 2 diabetic rats.

Objective: To observe the effects of erigeron injection on the biochemical indicators of hepatotoxicity caused by ischemia and reperfusion of the mice intestine.　Methods:A experimental model of liver lesion induced by ischemia－reperfusion of the mice intestine was set up. Serum was obtained after 20 minutes of ischemia followed by 1 hour of reperfusion. Contents of SOD and MDA in liver were measured.　Results: The serum ALT significantly increased following ischemia and reperfusion, which was attenuated by the erigeron injection (P＜0.01). Erigeron injection can also increase the contents of SOD and MDA in the mice liver (p＜0.05 and 0.01, respectively).　Conclusion: Erigeron injection can improve the biochemical indicators of liver lesion induced by ischemia and reperfusion of the mice intestine. It is indicated that the protective effects of erigeron injection was related to anti－oxidation mechanisms.

Objective To find the possible relationship between defects in the FA/BRCA pathway of genomic maintenance and potential pathogenesis of acute myeloid leukaemia.Methods Twenty-five AML cell lines derived from diverse subtypes of AML were screened to investigate for possible defects in FA,BRCA patllway.Results The absence of FANCN protein in two cell lines,THP-1 and M-07e were observed,which was correlated with the results of MMC-induced G2 arrest,growth inhibition and chromosomal breakage test in both cell lines.But no gene aberrance in these two cell lines by MLPA test and DNA sequencing were found.Conclusion There is a possible relationship between defects in the FA/BRCA Dathway and potentialpathogenesis of acute myeloid leukaemia.A disturbance of theFA pathwaymay represent an early event in the development of this type of leukaemia.
