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.

Objective To explore the protective effects and possible mechanisms of Polydatin (PD)on hypoxic-ischemia brain injury(HIBD) in neonatal rat by means of spatial learning memory and the expression of synaptophysin in hippocampal CA1. Methods Thirty-seven neonatal SD rats were divided into 3 groups at random: normal sham-operated group( no hypoxia and ischemia); HIBD group( no medication) ;PD treatment group. 7-old-day rat' s model of HIBD was established by left carotid artery ligation and 2 h hypoxia. Morris water maze test was used to evaluate cognitive function in the rats after 28-day-old( 21-day later after HI). Immunohistochemical method was used to measure the expression of synaptophysin after the end of Morris water maze test. Results Morris water maze results showed that the mean escape latency of the shamgroup (SG) ,HIBD group (HIBD) and PD treatment group (PD) were (39. 55 ±8. 08) s, (52. 37 ±8.03) s and (43.29 ± 7. 63 ) s respectirely. For PD and SG, the mean escape latency was significantly shorter than the HIBD (P ＜0.05). After training,the mean escape latency in the three groups of rats was shortened gradually. The frequency of platform crossings were 5. 29 ±2.62、2. 36 ± 1.80、4. 25 ± 1. 66 in the SG,HIBD and PD respectirely. The frequency of platform crossings in PD was higher than that of HIBD ( P ＜ 0. 05 ). The swimming time in target quadrant were ( 15.74 ± 3.85) s, ( 10. 63 ± 3.66) s and ( 14. 32 ± 2. 52 ) s in SG, HIBD and PD respectirely. For HIBD ,the swimming time in target quadrant was significantly shorter comparing to SG and PD ( P ＜ 0. 05 ). The expression of synaptophys in hippocampal CA1 in PD ( 0. 295 2 ± 0. 044 3 )were evidently higher than that in the HIBD group (0.261 2 ±0.032 3) at 3 week after operation (P ＜0. 05). Conclusion Spatial learning memory deficits and the decrease of synaptophys in hippocampal CA1 could be induced by hypoxic-ischemia. Polydatin could improve the learning and memory ability in neonatal rats following hypoxic-ischemia brain damage. The mechanisms of improvement with Polydatin treatment is associated with the enhancement of expression of synaptophys.
