Objective To study the role of bone turnover markers in multiple myeloma(MM)bone disease.Methods Thirty-eight MM patients were studied.Serum and urine samples were taken before,after 3 months and 6 months therapy.Serum samples of tartrate resistant acid phosphatage isoform-5b(sTRACP-5b),bonespesific alkaline phosphatase(sBAP),osteocslcin(sOC),urine samples of N-telopeptides of type Ⅰ collagen(NTX)were measured.Results Urine NTX concentrations were significantly higher in newly diagnosed and relapsed or refractory patients than that in pleateum patients and controls.serum TRACP-5b concentrations were significantly higher in newly diagnosed and relapsed or refractory patients than that in controls.There were no statistical significance compared with pleateum patients.Serum BAP concentrations were significantly lower than that in pleateum patients and controls.Serum OC concentrations were not statistically significant among the newly diagnosed patients,relapsed or refractory patients,pleateum patients and control.In newly diagnosed patients.urine NTX levels were significantly higher in stage Ⅲ than that in stage Ⅰ/Ⅱ,serum BAP levels were significantly lower in stage Ⅲ than that in stage Ⅰ/Ⅱ.There was a positive relationship between urine NTX and serum TRACP-5b in newly diagnosed patients.Urine NTX levels were significantly decreased,and serum BAP levels were significantly increased after 3 cycles effective therapy.There was no change in serum TRACP-5b and OC.Urine NTX and serum TRACP-5b were significantly diseased,serum BAP and OC were significantly increased after 6 cycles of effective therapy.But bone lesions on X-ray did not diminish at that time.Conclusion There is a closely relationship between bone turnover markers and bone lesions in MM.The bone turnover markers may be useful in monitoring MM progress and therapy.

Objective To provide a new way for treatment of full thickness skin defects by embryonic stem(ES) cell-derived epidermal-like stem cells. Methods Epidermal like stem cells,labeled by Hoechst 33342 and carried by a layer of biomembrane,were transplanted into the defective skin of mice.The differentiation tissue of donor cells was sampled each week.The sections were observed with HE staining,immunohistochemical and di-labeled immunofluorescence methods to test the expression of ?1 integrin,CK15,CK19,CK10,CEA. Results The full thickness skin defects were healed in 2 weeks.The newborn skin was thicker than the normal skin.The basal layer cells proliferated.There were more bulky cellular poles towards dermis.The cells labeled by Hoechst 33342,located in the newborn epidermis and tubular or follicular structures in dermis,expressed ?1 integrin and CK15 positive respectively in the first 3 weeks.There were sweat gland-like,sebaceous gland-like and hair follicle-like structures in the newborn dermis after 4 weeks.Basal cells of keratinized stratified squamous epithelium expressed CK19 and CK10 positive respectively and sweat gland-like structure expressed CEA positive.Conclusion ES cell-derived epidermal stem cells can restore mice full thickness skin defects.There are epidermis,sweat gland-like,sebaceous gland-like and hair follicle-like structures in the newborn skin.

Objective To establish a simple , practical , highly-effective and stable method for the isolation and cultivation of rat hair follicle cells. Methods Under sterile condition, single hair follicle was taken out after the skin around the barbel of SD neonatal rats was sheared off. And then the hair follicles were digested with two-step method with Type Ⅰcollagenase and trypsin. The obtained cell suspension was planted into the culture plate which was covered with extracellular matrix, and then was cultivated with K-SFM culture medium containing fetal bovine serum with volume fraction of 1%. On the next day, K-SFM culture medium was replaced with serum-free culture medium. The remaining tissues were cut into pieces and spread out in the culture flask, and then were cultivated with HG-DMEM culture medium containing serum. Two kinds of cells were harvested and then were identified by immunofluorescence. The hair follicle epithelial cells were tested by flow cytometer. Results The hair follicle epithelial cells obtained through the above methods showed rapid adherence, and were round or polygon-like , with typical cobblestone-like morphology. The long spindle-shaped cells were seen around the tissues cultivated, having many protrusions on the surface of the cells, and they were interconnected into reticular structure. The expression of cytokeratin 15, cytokeratin 19 and β1 integrin in epithelial cells were positive. Most of the epithelial cells were in the G1 phase, accounting for 75.6%. The expression of laminin ( LN), fibronectin ( FN) and vimentin in the connective tissue sheath cells were also positive. Conclusion The cells harvested by modified two-step enzyme digestion method have confirmed as hair follicle cells and fibroblasts, and the obtained cells are of rapid adherence, good homogeneity, and active proliferation.

Objective To explore the feasibility of repairing skin defect with Pelnac tissue engineering skin and cultured epidermal stem cells ( ESCs) and fibroblasts. Methods ESCs and fibroblasts in SD rats were isolated and cultured in vitro, and then were detected by immunohistochemistry. Fibroblasts were seeded in Pelnac material to construct dermis, and ESCs were seeded on the surface of dermis to construct tissue engineering skin. Thirty BALC/c nude mice were randomly divided into groups A, B and C. After mouse back skin defect model was established, group A was transplanted with Pelnac material, group B was transplanted with compound of Pelnac and fibroblasts, and group C was transplanted with Pelnac tissue engineering skin. The wound healing was observed after operation. The wound tissues were sampled for pathological histology test on the 5th and 7th day after transplantation. Results The expression of cytokeratin 15 and β1 integrin in ESCs was positive, and the expression of laminin ( LN) and fibronectin ( FN) in fibroblasts was positive. In group C, the wound healing of nude mice was the best, characterized by the proliferation of fibroblasts, obvious new capillaries and regularly arranged epidermal cells at the transplantation sites. Conclusion Pelnac tissue engineering skin has good effects on promoting repair of skin defect of nude mice.
