OBJECTIVE: To observe the effect of Chinese and western medicine integration on the spinning behavior of rats with Parkinson disease. METHODS: Model of the lateral Parkinson disease was made with injection of 6-hydroxydopamine (6-OHDA) into the black substance of the right side of the brain, and the model rats were treated with madopar and Chinese herbs for nourishing the liver and kidney, clearing collaterals and detoxification. The rat's spinning behavior was observed, and was compared with the normal control group, madopar group and sham-operation group at the same time. RESULTS: Chinese and western medicine integration could obviously reduce the spinning circles of the rats. CONCLUSION: Chinese and western medicine integration can significantly improve the spinning behavior of the model rats.

Objective To illustrate the effect of Madopar on nerve cell apoptosis of rats with Parkinson’s disease (PD). Methods Hemi-lateral PD model was made by injecting 6-OHDA into the black substance of the right side of the brain and treated with Madopar. At the same time,the normal group and sham-operation group were set up,and TUNEL staining and transmission electro-speculum were employed to observe the apoptosis of nerve cells. Results The TUNEL positive cells(23.50?3.85) were significantly less than the model group(37.83?6.46) and the comparison of apoptosis cells counting showed marked difference( P

Background and purpose:In recent years, epigenetics research has become a new direction of cancer research. A large number of results have shown that the abnormal changes of epigenetic modifications have close connection with cancer. Genome-wide epigenetic modifications have become new markers for cancer. This study aimed to investigate the methylation of the promoter ofDBC1 gene in cervical cancer tissues of Uyghur women in Xinjiang, to explore the correlation between the gene methylation and the infection of HPV, and to evaluate whether it can be used as a tool with high sensitivity and specificity for cervical cancer screening.Methods:This study detected the infection of HPV16, 18 in 43 normal cervical tissues, 35 cervical intraepithelial neoplasia tissues and 54 cervical cancer tissues using the polymerase chain reaction (PCR) method. The methylation of the promoter ofDBC1 gene in above-mentioned tissues was detected by the methylation-specific PCR method. The expression ofDBC1 at mRNA level was measured by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) in 10 methylation-negative normal cervical tissues and 10 methylation-positive cervical cancer tissues.Results:In normal cervical tissues, CIN tissues and cervical cancer tissues, the infection ratios of HPV16 were 18.6%, 34.3% and 68.5%, respectively; the infection ratios of HPV18 were 2.3%, 8.6% and 16.7%, respectively; and the methylation ratios ofDBC1 gene were 23.3%, 40.0%, 87.0%, respectively. In 79 high-grade squamous intraepithelial lesions (CINⅡ and Ⅲ) and cervical cancer tissues, 50 of 79 were infected with HPV16/18, while 29 of 79 were negative. The methylation ratio ofDBC1 gene was 88.0% in HPV16/18 infection positive group while the methylation ratio was 55.2% in negative group (P<0.05). The expression ofDBC1 gene at mRNA level in 10 methy- lation-positive cervical cancer tissues was significantly lower than that in the 10 methylation-negative normal cervical tissues (P<0.05).Conclusion:The methylation ofDBC1 gene may become a molecular marker to detect cervical cancer of Uyghur women in Xinjiang.DBC1 gene methylation combined with HPV16/18 infection test can be used to aid diagnosis of cervical cancer.
