Objective To investigate the relationship between plasma cell mastitis and prolactin. Methods The relationship between the lesion area , degree of inverted nipple and prolactin level of 228 plasma cell mastitis patients were observed , as well as their prolactin level before and after treatment , to explore the factors that influence relapse. Results There was no significant statistical relationship between prolactin level and lesions area and degree of inverted nipple. Prolactin level before and after treatment were statistically different (t =2.347,P = 0.02). Menstrual status, nipple status, comorbidities, lesion area and prolactin level were considered, only prolactin level was related with disease recurrence (P = 0.038). Conclusion prolactin level could significantly reduced as the disease cured , but elevated prolactin may lead to relapse of the disease.

Objective To know the accumulation and movement of heavy metals in the environment through sewage sluge using in agriculture. Methods The sewage sludge samples were collected from sewage treatment farms of Suzhou, Wuxi and Changzhou in the different seasons of 1998. The content and states of heavy metals were determined by AAS. The accumulation and movement of heavy metals were analyzed as sewage sludge was used in agriculture. Results The content of heavy metals in the sewage sludge was greatly higher than that in the soil background. Especially, the contents of zinc in the sewage sludge in three cities exceeded the related standard, the means were 1 199.00, 784.00 and 1 216.00 mg/kg respectively. A long term using of sewage sludge might induce heavy metal accumulation in the soil. Conclusion Sewage sludge used in agriculture may induce heavy metal accumulation in the soil and the organisms, so the risk of environmental heavy metals accumulation may increase.

Objective To investigate the effect of immunosuppressive drugs on the activity of pancreatic islet cells, and to explore their role in islet allotransplantation. Method Human pancreatic islet cells were isolated and purified in vitro, and their activity was determined by MTT assay after incubation with immunosuppressive drugs in different concentrations. Results The activity of the islet cells was not reduced after exposure to rapamycin at lower concentrations, although exposure to rapamycin at higher concentrations (≥1ng/ml) was associated with a significant inhibition of activity. No reduction of islet cell activity was observed after exposure to daclizumab and FTY720, at either lower or higher concentrations. Conclusion Rapamycin acts to damage islet cells directly, and the degree of the damage was concentration-dependent. No obvious toxicity to the islet cells was observed after exposure to daclizumab and FTY720.

BACKGROUND: Transplantation of microencapsulated rabbit Schwann cells in the rat spinal cord can relieve inflammatory reaction, promote spinal cord regeneration, but the precise mechanisms remain unclear. OBJECTIVE:To observe basic fibroblast growth factor (bFGF)expression and movements recovery following transplantation of microencapsulated rabbit Schwann cells in rat spinal cord. METHODS: The sciatic nerves taken out from rabbits wore digested with mixed enzyme and were made into Schwann cells suspension. Then we used air-jet method to make Schwann cells microcapsule. Using the same method, empty microcapsule was made. Sprague Dawiey rats were randomly divided into cell group, empty microcapsule group and microcapsule group. Conducted by hemisection injury of spinal cord,the rats in cell group,empty microcapsule group and microcapsule group were implanted with gelatin sponge with 10μL Schwann cells suspension, gelatin sponge with 10 μL empty microcapsule and 10 μL microencapsulated Schwann cells. Normal group was left intact. After operation, we observed hindlimb movements recovery in rats with the Basso, Beattie, and Bresnahan (BBB) scale. Meanwhile,a set of sections were stained immunohistochemically for bFGF expression, another set of sections wore stained for hematoxylin-eosin and Nissal. RESULTS AND CONCLUSION: After spinal cord injury, rat right hindlimb affected paralysis immediately. At 7, 14 and 28 daysfollowing transplantation,motor function in rat hindlimb was significantly recovered, and the BBB scores were significantly higher in microencapsulated schwenn cells than in cell and empty microcapsule group (P < 0.05 or P < 0.01). bFGF positive products were mainly distributed in cytoplasm of the spinal neuron and nucleus of neuroglical cell. The numbers of bFGF positive glial cells mainly appeared surrounding the spinal cord injured site on days 1, 3, 7 and rose to its peak on day 3 and began to appear in neuronal calls on day 14. The number of bFGF positiv cells in microcapsule group was significantly superior to that in cell group and empty microcapsule group. From then on, the bFGF expreSsion was significantly decreased in each group. These indicated that transplantation of microencapsulated Schwann cells can inhibit the immunological rejection after xenotransplantation, suppress inflammatory reaction, improve the expression of bFGF, increase hindlimb movements recovery and spinal cord regeneration after spinal cord injury.

Objective Hermaphroditic planarians possess a very important position in the systematic evolutionary history of animal, as they are capacity of complete regeneration. Hence, the research on histological structure of autofluorescence has been carried out to provide a crucial insight into the developmental and regenerative biology. Methods Part of histological structure of planarian (Dugesia japonica) was revealed with HE method, Masson method and Van Gieson method. Their autofluorescence was observed with ultraviolet. There were six planarians in each stained group and the autofluorescence group. Results Epidermis, outer epidermis of pharynx, protonephridium, intestine, the photoreceptor cells and longitudinal nerve cords, all radiated blue autofluorescence. The epithelial dissociation side of copulatory bursa radiated yellow autofluorescence, its middle part radiated blue autofluorescence, its fundus side radiated weakly blue autofluorescence. Testis could hardly give off autofluorescence. Pigment cells of eyepot could not give off autofluorescence. Conclusion The research on configuration and autofluorescence of planarian eye may offer help for the study of origin and evolutionary law on eye of invertebrate.
