ERK1/2、p-ERK1/2 and cleaved caspase-3 protein expression were measured by Western blot .Results Silymarin inhibi-ted the proliferation of Saos-2 cells in a time-dependent and concentration-dependent manner . Silymarin in-duced the apoptosis of Saos-2 cells in a concentration-dependent manner . Silymarin decreased p-ERK1/2 protein expression and increased cleaved caspase-3 protein expression in a concentration-dependent man-ner, while ERK1/2 protein expression had no obvious change.Conculsions Silymarin can inhibit the prolif-eration of human osteosarcoma saos-2 cells and induce apoptosis of them , and the mechanism may be related to inhibition of ERK signaling pathway and upregulated caspase-3 protein expression .

0. 05), respectively. Conclusion: Repeated +Gz stress may disorder the ratio of ET and NO. This imbalance may be one of the causes which lead to pathology changes in masseter musscles.

The nerve tissue engineering is to apply scalfolds and seed cells for the treatment of injury or disease of nerve system by restoring their anatomic structures and funetiorm.The scaffolds played important roles in supporting and conducting axonal regeneration.They could also limit the in-growth of scar tissue and hence help to build the connection between axonal and target cell.Self-assembling peptide scaffold is one of the excellent material used is nerve tissue engineering.This article reviews the self-assembling peptide based scaffolds for nerve tissue engineering and discusses the unsolved problems in the fields and the trend d the related research in the future.

Objective To probe into the effect of the enteral nutrition added with lactobacillus on gastric bacteria of rats with severe brain injury. Methods Severe brain injury was made in rats that were then fed with enteral nutrition (3-9 entire nutrients), lactobacillus (3-9 entire nutrients + lactobacillus) and synbiotics (3-9 entire nutrients + lactobacillus + fiber) respectively. Gastric body and gastric antrum mucosa were collected at day 1, 3 and 7 after injury to detect the change of the gastric bacteria. Results DCCE analysis showed less bacteria in sham operation group. On the first day after severe brain injury, the flora bands were increased remarkably but the number of bacteria was decreased in three groups. The similarity of denaturing gradient gel electrophoresis ( DGGE) map patterns was 65% , 64% and 53% respectively in the enteral nutrition group, lactobacillus group and synbiotics group, with no significant difference in regard of the diversity index. On the third day after severe brain injury, the flora bands showed a tendency of decrease, with the similarity of denaturing gradient gel electrophoresis (DGGE) map patterns for 72% , 58% and 62% respectively. The richness and diversity of total bacteria in the lactobacillus group was remarkably lower than that in the enteral nutrition group and synbiotics group (P＜0.01). On the seventh day after SHI, the flora bands were decreased in three groups, with the minimum number of the bacteria. The similarity of denaturing gradient gel electrophoresis ( DGGE) map patterns was 61% , 51% and 58% respectively, with higher richness and diversity of total bacteria in the synbiotics group compared with the other groups. Conclusion Lactobacillus can help improve gastric bacteria disturbance of rats with severe brain injury. In the meantime, addition of the lactobacillus is better than addition of the synbiotics.

Objective To explore the biological characteristics of mucinous adenocarcinoma deriving from chronic anal fistula and its diagnosis and treatment. Method A retrospective study was made to analyze clinical and pathological features of 4 cases of chronic anal fistula from which mucinous adenocarcinoma developed in our hospital from 1986 to 1997. Results There were three males and one female averaging 50 years old. All patients had chronic history of perianus abscess or anal fistula. This rare mucinous adenocarcinoma originated from the anal fistula and the associated anal glands. The canceration of anal fistula was due to chronic inflammation and scarring. The definitive diagnosis of the carcinoma depends on biopsy of the fistula and the related tumor. Metastasis to groin lymph nodes was found in two patients. Three cases underwent Miles operation with chemotherapy; two of the three patients also had resection of groin lymph nodes. Three patients survived more than five years. One patient treated only with chemotherapy died three months later. [WT5”HZ] Conclusion [WT5”BZ] Mucinous adenocarcinoma following chronic anal fistula is less malignant and has better prognosis compared to primary rectal and anal mucinous adenocarcinoma.
