125 Wistar rats were divided into five groups randomly. The experimental period was 20 weeks. The results showed that both in the rats drinkcd water containing 6mM Li_2CO_3. and the rats with iodine-deficiency alone, their thyroid gland increased in weight and showed a pattern of hyperplatic goitre; their serum T, dropped which T_3 was increased. These changes were more marked in the rats with iodine deficiency and the activity of thyroid superoxidas strengthened. But in the rats that drinked water containing 6mM Li_2CO_3 there was more colloid in the follicular lumens of the thyroid. Under the condition of iodine deficiency, the rats that drinkcd water containing 3mM and 6mM Li_2CO_3 had larger and heavier thyroid gland, and their serum T_4 dropped which T_3 remained normal. Compared with the rats which had iodine deficiency along, their thyroid glands showed a typical picture of colloid goitrc. In the iodine deficiency rats which drinked water containing 3mM Li_2CO_3 the change of the thyroid gland was even more marked.

Objective To compare the efficacy of different does of remifenanil combined with propofol for colonoscopy.Methods Ninety ASA Ⅰ or Ⅱ patients,aged 35-63 yr,weighing 45-72 kg,scheduled for elective painless outpatient colonoscopy,were randomly divided into 3 groups (n =30 each):remifentanil 0.2 μg/kg group (group Ⅰ),remifentanil 0.5 μg/kg group (group lⅡ) and remifentanil 1.0 μg/kg group (group Ⅲ).In groups Ⅰ-Ⅲ,remifentanil 0.2,0.5 and 1.0μg/kg were injected over 60 s,respectively,and then propofol 1.0 mg/kg was injected intravenously for induction.The colonoscope was inserted after loss of eyelash reflex.When body movement appeared during examination,remifentanil 0.1 μg/kg + propofol 0.5 mg/kg,remifentanil 0.25 μg/kg + propofol 0.5 mg/kg,and remifentanil 0.5μg/kg+ propofol 0.5 mg/kg were added in groups Ⅰ,Ⅱ and Ⅲ,respectively.The operation time,induction time,emergence time,examination room discharge time,and body movement,hypotension,bradycardia,hypoxemia and respiratory depression during operation were recorded.Results There was no significant difference in the operation time,induction time,emergence time,and examination room discharge time between the three groups (P ＞ 0.05).Compared with group Ⅰ,the incidence of body movement was significantly decreased,and the incidences of hypotension and respiratory depression were increased in group Ⅱ,and the incidence of body movement was significantly decreased,and the incidences of hypotension,hypoxemia,bradycardia and respiratory depression were increased in group Ⅲ (P ＜ 0.05).The incidences of hypoxemia,bradycardia and respiratory depression were significantly higher in group Ⅲ than in group Ⅱ (P ＜0.05).Conclusion The optimum dose of remifentanil is 0.5 μg/kg when combined with propofol for colonoscopy.

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) are in advantages of easy collection and amplification in vitro, but the culture and induction in vitro still need to be modified. OBJECTIVE: To investigate the differentiated potency of BMSCs into ostcoblasts by modified in vitro culture methods and inductor matching. DESIGN: Observational study. SETTING: Department of Medical Laboratory, General Hospital of Guangzhou Military Area Command of Chinese PLA. MATERIALS: This study was performed in the Stem Cell Tissue Engineering Laboratory, Department of Medical Laboratory, Genera Hospital of Guangzhou Military Area Command of Chinese PLA from July 2004 to June 2006. Twenty adult SD rats of clean grade, irrespective of gender, weighing 140-180 g were provided by Animal Experimental Center, General Hospital of Guangzhou Military Area Command of Chinese PLA. The experimental animals were disposed according to ethical criteria. Β-sodium glycerophosphate, dexamethasone, and vitamin C were provided by Sigma Company, USA; goat-anti-rat osteocalcin antibody by DSL Company, USA; S-P immunohistochemical kit by Maixin Biotechnology Developing Co., Ltd., Fujian. METHODS: Cells were cultured and induced into osteoblasts by modified methods. Separation and culture of BMSCs: By anesthesia, bone marrow of bilateral femur and tibia was separated to prepare single cell suspension; subsequently, the suspension was inoculated in culture bottle, and the culture media was semi-quantitatively changed after 48 and 96 hours in order to get rid of non-adherent hematopoietic cells. The liquid was changed every three days to further get rid of non-adherent cells. At 80% cell confluence, the medium was digested with 0.25% trypsin and cells were subcultured in the ratio of 1:2. MSCs in the second generation were inoculated in 6-well culture plate and glass fiat plate; after 48 hours, basic culture fluid was removed. Differentiation of BMSCs into osteoblasts: Subcultured BMSCs differentiated into osteoblasts induced by dexamethasone (10 mmol/L), β-sodium glycerophosphate (10-7 mol/L), and vitamin C (50 mg/L). MAIN OUTCOME MEASURES: Ten days after differentiation by modified culture methods and inductor matching, alkaline phosphatase activity was measured with Ca-Co technique. Twelve days after culture, osteocalcin secretion was detected with immunohistochemical method. Two weeks after culture, cell mineralization was detected with Von kossa staining. RESULTS: Alkaline phosphatase activity: Alkaline phosphatase staining of cells was apparent; gray-black particles or massive precipitations were observed in cytoplasm after positive reaction; regions expressing alkaline phosphatase activity were brown-black. Osteocalcin secretion: Osteocalcin was apparently positive; nucleus was blue; cytoplasm was brown. Cell mineralization: Induced cells grew layer by layer, and adiaphanous nodus was observed at the same time. Black mineralized nodus granules in various sizes were observed after Von kossa staining, and this suggested that mineralized apposition occurred. CONCLUSION: BMSCs may be successfully cultured and induced into osteoblasts by modified culture method.
