ABSTRACT
Objective:To detect the expressions of p16INK4a protein in the cervical lesion tissues of the Mongolian patients, and to explore the relationship between its expression and the occurrence and development of cervical cancer in the Mongolian patients.Methods:A total of 100 cases of paraffin sections of cervical cancer, cervical intraepithelial neoplasia(CIN),chronic cervicitis and uterine leiomyoma were divided into 25 cases of cervical cancer, 35 cases of CIN, 20 cases of chronic cervicitis, and 20 cases of uterine leiomyoma groups. The expressions of p16INK4a protein in different cervical tissues were detected by immunohistochemical SP method.Results:The positive rates of p16INK4a protern in cervical cancer, CIN, chronic cervicitis and uterine leiomyoma tissnes were 100.0%, 74.3%, 25.0%,and 10.0%, respectively.The results of K-W H rank sum test for multiple sample comparisons showed that the positive expression rate of p16INK4a protein in cervical cancer tissue was significantly higher than those in CIN, chronic cervicitis and uterine leiomyoma tissues(P<0.05).Conclusion:p16INK4a protein can be used as a indicator to screen the Mongolian patients with early cervical cancer.
ABSTRACT
Objective To observe the effect of Mongolian medicine Tonglaga-5 Pill on the osteoporosis induced by retinoic acid in the rats,and to provide experminted basis for its clinical application.Methods 60 female Wistar rats were randomly divided into blank group,model group,Ossptide Tablets group,Tonglaga-5 Pill groups with low,medium and high doses (n=10).The osteoporosis models were induced by retinoic acid in the rats.The levels of serum calcium (Ca), phosphorus (P), alkaline phosphatase (ALP), transforming growth factorβ1 (TGF-β1),insulin like growth factor (IGF-1)and bone indexes were detected and the contents of Ca and P in ash were also detected,and the changes of bone histomorphometry of the rats were observed under light microscope by HE staining.Results Compared with model group,the serum calcium and P contents of the rats in Tonglaga-5 Pill groups were increased,but there were no significant differences (P>0.05);the ALP levels were decreased significantly (P0.05);the contents of calcium and P in ash were increased in different degrees,but there were no significant differences (P>0.05).Compared with control group,the femur maximum width index and minmum width index of the rats in model group were significantly decreased (P0.05).Under light microscope,the rich and full bone trabecula was found in the rat femur in control group;the bone trabecula in model group was decreased,and the bone trabecula in Tonglaga-5 Pill groups was increased. Compared with model group, the trabecular bone areas in Tonglage-5 pill groups and Ossotide group were increased (P<0.05).Conclusion Tonglaga-5 Pill displays a certain preventive effect on the rats with retinoic acid-induced osteoporosis,which can blocks the bone mineral loss,bone tissue structure changes and bone quality decreasing effectively.
ABSTRACT
Objective To figure the clinical characteristics and genetic bases of Dentinogenesis imperfecta type Ⅱ in a large Mongolian family.Methods Systematic analysis for this family was carried out using clinical detection. Results Affected individuals of Dentinogenesis imperfecta type Ⅱ were consecutively found in a five-generation family. The morbidity of the offsprings is nearly 1/2 and no sexual difference is found. The analysis of clinical features as well as dental x-ray check showed specific finding that were not found in other families. Conclusion Dentinogenesis imperfecta type Ⅱ in this Mongolian family pertains to autosomal dominant disorder with high genetic heterogeneity in clinical phenotype. Further study is warranted to identify the association of this heterogeneity with lifestyle or genetic information.
