BACKGROUND: Based on the characteristics of cartilage tissue, such as consisting of single type of cells, the cartilage cells or chondrocyte, absence of blood vessel, rather low consumption level of oxygen and nutrition, low level of allo-immunocompetence and simple function in vivo, it seems to be easy for cartilage cell lines to be established for tissue and cell transplantation. We want to set up a cell line with the purpose of current use in tissue engineering in vitro. It will provide the basis for artificial tissue and organ that will become to be standardized and yielded in batch.OBJECTIVE: To explore the potential stimulatory effects of basic fibroblast growth factor(bFGF) and insulin on the proliferation and differentiation in primary culture mice chondrocytes in vitro. The effect and application of the cell factors will be evaluated for tissue engineering.DESIGN: A grouping controlled and repeated trial was conducted with the cells as the subjects.SETTING: Key laboratory of tissue transplantation and immunology of a college.MATERIAIS: The experiment was completed in the Key Laboratory of Tissue Transplantation and Immunology of the Ministry of Education, Jinan University from November 2002 to May 2003. Cultured cartilage cells at random were obtained as the study objects.METHODS: Mice cartilage cells were cultured in medium at the minimum concentrations of serum. The effects of different concentration of bFGF and insulin on the proliferation and differentiation in mice cartilage cells were observed with WST1 and immunofluorescence staining.MAIN OUTCOME MEASURES: Primary results: ① Effect of bFGF on proliferation of primary cultured mice cartilage cells. ② Effect of insulin on proliferation of primary cultured mice cartilage cells. Secondary results:morphological observation of cartilage cells RESULTS: Primary cultured mice cartilage cells were cultured in medium at the minimum concentration of serum(4 g/L fatal bovine serum). It was found that bFGF and insulin might play an important role on the proliferation and growth of mice cartilage cells in a dose-dependent manner. In addition, morphological observation of cartilage cells showed that both bFGF and insulin not only promoted the proliferation of the cells but also enhanced the matrix secretion of cartilage cells.CONCLUSION: Both bFGF and insulin can stimulate the proliferation of cartilage cells in vitro.

OBJECTIVE: To discuss the role of carbon nanoparticles in the protection of parathyroid during thyroid carcinoma surgery. METHOD: Seventy-two patients with thyroid carcinoma who had initial surgery were randomly divided into two groups: carbon nanoparticles group and the control group. Emulsion of carbon nanoparticles was injected into the thyroid gland of carbon nanoparticles group patients. After thirty minutes,the excision of thyroid carcinoma and VI group neck dissection were performed in carbon nanoparticles group patients, the control group directly underwent operation. The black stained tissue in the dissection specimen of carbon nanoparticles group was separated. The number of total lymph node,metastasis lymph node and parathyroid gland in the tissure black stained or not in two groups were counted respectively. RESULTS: There were 312 lymph nodes in the black stained tissue of central compartment dissection specimen of carbon nanoparticles group. No parathyroid gland was found in the black stained tissue. Fifteen lymph nodes containing four parathyroid glands were found in the non black stained tissue in carbon nanoparticles group while there were 202 lymph nodes containing 13 parathyroid glands in the control group. There were statistical difference between the amount of lymph node in black stain tissue and the specimen of the control group. Parathyroid glands were not stained black,and no parathyroid gland was found in the black-stained tissue. CONCLUSION The carbon nanoparticles could be used to identify the lymph node and the parathyroid gland for protecting the parathyroid gland in thyroid surgery.
