Résumé
Objective The aims of this study were to determine the expression of Ki-67 and PTEN in oral adenoid cystic carcinoma( OACC) and its relationship with clinicopathological features,and to explore the re-lationship between the expression of Ki-67 and PTEN. Methods Forty cases of oral adenoid cystic carcinoma were collected from the pathological laboratory in our hospital. Another 15 cases of normal gland in patients with oral adenoid cystic carcinoma were selected as the control group. The expression of Ki-67 protein and PTEN in adenoid cystic carcinoma was detected by immunohistochemistry. Results The positive rate of Ki-67 protein in oral adenoid cystic carcinoma was 70%(28/40),which was significantly higher than that in the control group(2/15)(P<0. 05). The positive rate of PTEN in oral adenoid cystic carcinoma was 63%(25/40),which was signif-icantly higher than that in the control group 20%(3/15)(P <0. 05). They were associated with histological types,metastasis,lymph node metastasis and neural invasion,and not correlated with age,gender and tumor loca-tion. The expression of Ki-67 and PTEN in oral adenoid cystic carcinoma may have a significant correlation. Conclusion The expression of Ki-67 and PTEN in adenoid cystic carcinoma is high,and their occurrence and development in adenoid cystic carcinoma play an important role in the process of evolution and metastasis. Ki-67 and PTEN proteins may be markers of oral adenoid cystic carcinoma.
Résumé
Objective To discuss the common nature of live depression and spleen qi deficiency and liver disease and the changes after the intervention ofXiaoyaopower by the metabonomics method. Methods A total of 40 rats were randomly devided into the normal control group, the liver depression and spleen qi deficiency model group, the liver depression and spleen qi deficiency treatment group, the liver disease group, the liver disease treatment group, 8 in each group. The liver depression and spleen qi deficiency model rat was established by tail-clamping infuriation and Senna gavage method, and the liver disease model rat was established by the CCl4-induced liver injury method. The rats of the liver depression and spleen qi deficiency treatment group and the liver disease treatment group were given 2 g/mlXiaoyao powder, and other groups were given the equal-volume saline. All the treatment lasted 28 days. Twelve hours after the last administration, rat metabolite profiling and contents in the serum were detected by GC-MS, the change of rat liver tissue was observed through HE staining.Results The rats of liver depression and spleen deficiency pattern and liver disease model group appeared liver cell nuclei atrophy, dissolution, degeneration necrosis and lymphocyte infiltration, and at the same time the contents of Glycine, Butanediodic acid, Propanoic acid, Methionine, Glutamine, Phenylalanine in serum were all higher than the normal control group (P<0.05). AndXiaoyao powder could reduce the content of the contents of Glycine, Butanediodic acid, Propanoic acid, Methionine,Glutamine, Phenylalanine in serum (P<0.05).ConclusionXiaoyao powder may play the role of protecting liver by the regulation of one carbon unit, sulfur containing amino acids, aromatic amino acids and amino acid of special metabolism and three tricarboxylic acid cycle.

Objective To study the effect of Schisandra chinensis on the treatment of glomerular nephritis in rats by gas chromatography mass spectrometry (GC-MS).Methods The rats were randomly divided into normal group, model group, and the treatment group, 10 rats in each group. We employed the C-BSA injuction to induce situ immune complexes nephritis rate model. Then 24 hour urinary protein was detected after 12 days and a urine metabonomic technology combined with pattern recognition method was used to identify the network analysis, which focuses on the key metablites and enzmys with glomerulonephritis disease.Results After 12 days, compared with the control group, the 24 h urinary protein content (9.24 ± 2.69 mg vs. 76.04 ± 18.88 mg) significantly decreased (P<0.01). Urine metabonomicsi dentified 15 endogenous biomarkers, which included unsaturated fatty acid biosynthesis, pyruvate metabolism and glycolysis metabolism. These metabolic pathways are associated with kidney diseases.Conclusion The effect of Schisandra chinensis on glomerular nephritis may treated by regulating the metabolism of arachidonic acid and fatty acid in four.
