BACKGROUND: Dedifferentiation changes in monolayer culture and limited resource are 2 problems in chondrocyte study. There are few reports concerning the phenotype, biological characteristics, and three-dimensional culture SW1353 human chondrosarcoma cells.OBJECTIVE: To observe the kinetics characteristics and ultramicro location of type Ⅱ collagen in three-dimensional cultured SW1353 human chondrosarcoma cells.DESIGN, TIME AND SETTING: The material-cytology in vitro observation was performed at the Xiangya School of Medicine, Central South University, from August 2004 to January 2006.MATERIALS: SW1353 human chondrosarcoma cells were provided by ATCC Company.METHODS: After resuscitation, the cells were cultured in DMEM containing fetal bovine serum and vitamin C. Then the cell aggregate was suspended in alginate solution, with final concentration of 2×10~9/L, gel solution was dropped to obtain alginate beads. At weeks 8 after three-dimensional culture, citrate sodium was added to breakdown gel, and the chondrocyte was harvested. The growth characteristics of SW1353 between in monolayer and in alginate three-dimensional were compared. MAIN OUTCOME MEASURES: Phenotype shift was observed by Toluidine blue staining. Type Ⅱ collagen expression in cell was directed by immunohistochemistry. The location of type Ⅱ collagen in ultrastructure was observed by Immunoelectron microscope. Isotope 14C-proline pulse chase experiment was performed to find out the kinetics of collagen Ⅱ in synthesis and secretion. RESULTS: There were phenotype changes after 8 weeks monolayer cultured in SW1353 as the articular chondrocytes had done. Compare with the monolayer culture, the good phenotype was maintained and the proliferation was slow when the cell was cultured in alginate culture and the type Ⅱ collagen in suspension and alginate matrix was decreased either. Type Ⅱ collagen expression in cell can be directed both in cells and outside of cells; type Ⅱ collagen locate almost in rough endoplasmic reticulum in Immunoelectron microscope; Pulse chase experiment found that the 180 minute was the peak of synthesis and secretion of collagen Ⅱ after intervention by ~(14)C-proline. ELISA confirmed that the expression of type Ⅱ collagen was obvious increased at 8 weeks than 1 week in the suspension of monolayer culture (P < 0.05), which was greater than that in alginate matrix of three-dimensional. CONCLUSION: Long term monolayer culture in SW1353 may lead to cell phenotype change. Alginate three-dimensional can improve the phenotype changes by decrease cells metabolism and maintaining the dormancy situation of SW1353. Expression of type n collagen in SW1353 was abundant. This cell line can be a good research model of chondrocyte function.

OBJECTIVE:To study improvement effect of modified mahuang chanyi decoction on allergic rhinitis(AR)model guinea pigs and its mechanism. METHODS:32 guinea pigs were randomly divided into normal group (0.9% Sodium chloride in-jection),model group (0.9% Sodium chloride injection),experimental [Modified mahuang chanyi decoction,5.18 g (medicinal materials)/kg] group and control [Fluticasone propionate nasal spray,50 μg/(guinea pig·d)] group. Except for normal group,other groups received ovalbumin 30 mg and calmogastrin 30 mg intraperitoneally to induce AR model. Except for control group,other groups were given relevant medicine intragastrically,twice a day for consecutive 15 d. Nasal symptoms of guinea pigs were ob-served and recorded,and then analyzed and scored. The protein expression of nasal mucosa SHP-1 was detected by immunohisto-chemistry,the serum contents of IL-4 and IFN-γ were determined by enzyme-linked immunosorbent assay. RESULTS:Compared with normal group,model group suffered from AR symptom,and nasal symptoms score was increased;and the protein expression of nasal mucosa SHP-1 and the serum content of IL-4 increased,while the content of IFN-γ decreased(P<0.05). Compared with model group,AR symptom of experimental group and control group were improved;nasal symptoms score,the protein expression of nasal mucosa SHP-1 and the serum content of IL-4 decreased while the content of IFN-γ increased(P<0.05). CONCLUSIONS:Modified mahuang chanyi decoction shows certain improvement effect on AR,and its mechanism is associated the decrease of IL-4 content and the increase of IFN-γcontent in serum.

[ ABSTRACT] AIM:To investigate the effects of induced pluripotent stem cells-derived mesenchymal stem cells ( iPSC-MSCs) on cobalt chloride ( CoCl2 )-induced injuries of PC12 cells and its possible mechanism.METHODS:PC12 cells were exposed to CoCl2 to set up a chemical-induced cellular injury model and were cocultured with iPSC-MSCs.The cell viability was tested by CCK-8 assay.The apoptosis was measured by flow cytometry using Annexin V/PI staining.The mitochondrial membrane potential (MMP) was analyzed by flow cytometry using JC-1 staining.Immunofluorescence was employed to observe mitochondrial transfer from iPSC-MSCs to PC12 cells.RESULTS: Apoptosis of PC12 cells was in-creased and MMP of PC12 cells was decreased after exposed to CoCl2 at concentration of 400μmol/L for 24 h.Coculture of PC12 cells with iPSC-MSCs reduced the apoptosis and recovered the MMP of the PC12 cells.Tunneling nanotubes were formed between iPSC-MSCs and PC12 cells, through which the iPSC-MSCs transferred the mitochondria to the PC12 cells. CONCLUSION:iPSC-MSCs protect PC12 cells from CoCl2-induced injuries, which may be associated with the mitochon-drial transfer from iPSC-MSCs to PC12 cells.

Objective To analyze the clinical data of children with Langerhans cell histiocytosis (LCH),to discuss the therapeutic effect,and to analyze the factors related to prognosis.Methods A total of 45 children diagnosed as LCH were divided into group A (18 cases with bone lesion only),group B(6 cases with soft tissue lesion),and group C (21 cases with viscera lesion) according to Shanghai Children's Hospital-LCH-2007 scheme [SCH-LCH-2007 (modified DAL-HX83/90) scheme].(1) Initial treatment:group A was treated with Prednisone (Pred) + Vincristine (VCR) for 28 weeks,and group B was treated with Pred + VCR + Etoposide (VP16) + Mercaptopurine (6MP) for 43 weeks,and group C was treated with Pred + VCR + VP16 + Methotrexate (MTX) +6MP for 52 weeks.(2) Re-treatment scheme after relapse included:①upgrading treatment,group A to group B,group B to group C.②Individual treatment for group C included VP16 modification,and maintained Thymosin and/or Ciclosporin etc.Results The total survival rate was 93.3％ (42/45 cases) and recurrence rate was 26.7％ (12/45 cases).Children in group A and B were all effective,while 2 patients in group C died,and 1 case missed follow-up.Multi-factor analysis showed that the factors like age,sex,group,skeleton,soft tissue,erythra,lymph gland,lung,mouth,ears,hypophysis pituitary had no statistical significance,but liver,spleen and blood involvement had statistical significance in disease relapse:liver (P=0.007 1),spleen (P=0.016 9),and blood (P=0.011 1).Conclusion LCH can affect several organs of children and relapse,and modified DAL-HX83/90 scheme is very effective.The liver,spleen and hematopoiesis system involvement is correlates with the relapse.
