ObjectiveTo determine the source of IL-6 in detached retina and the change of IL-6 level in detached and reattached retina.MethodsRetinas of SD rat were examined after subretinal injection of 1.4% Healon GV at different period of time, and the level of IL-6 in detached and reattached retina were detected by radio-immune histochemistry method. Wax-embeded sections were labeled with IL-6 antibody to determine the location of IL-6.ResultsDetached retina with normal vitreous and inner limiting membrane could only induce the subretinal fibrosis. This kind of fibrosis reached to its peak at 10th day and then remolded with time. Retinal pigment epithelial (RPE) cell, Muller cell, endothelial cell, glial cell were labled with IL-6, and the level of IL-6 in neuro-retina reached to its peak at 3rd-4th day and then downed to normal within a few days. The level of IL-6 in reattached retina was lower than in detached retina. The expression of IL-6 in RPE of detached area was stronger than in attached area.ConclusionIL-6 takes active part in wound healing process induced by the separation of RPE and neuro-retina. Reattachment can lower the expression of IL-6 in retina.

BACKGROUND:Studies have shown that bone loss can lead to a series of diseases, such as osteoporotic fractures, thus seeking to increase bone mass has become a goal of the majority of researchers.
OBJECTIVE:To summarize the current studies of improving bone mass by using stem cel transplantation, hoping to the extensive application of stem cel transplantation in the clinical treatment of osteoporosis as early as possible.
METHODS:A computer-based search of PubMed and CNKI was performed by the first author to retrieve articles relevant to stem cel therapy for osteoporosis published from January 1997 to October 2014. The keywords were“to improve bone mass, regenerative medicine, bone marrow mesenchymal stem cel transplantation, stem cel therapy”in Chinese and English, respectively, which appeared in the title, abstract or keywords. Articles published recently or in authoritative journals were preferred, and final y 28 articles were included in result analysis.
RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cel s which are isolated and cultured easily can proliferate rapidly and have multi-lineage differentiation potential. Studies have shown that the osteogenic differentiation of bone marrow mesenchymal stem cel s can real y improve bone mass, and obtain more achievements in the treatment of orthopedic disorders. This new cel therapy can help to accelerate bone healing and reduce treatment time, offering a new therapeutic choice for orthopedic surgery, plastic surgery, oral and maxil ofacial surgery, and therefore, it has broad application prospects.

Objective To evaluate the effect of curcumin on the proliferation of and apoptosis in HaCaT cells induced by tumor necrosis factor α (TNF-α).Methods HaCaT cells were cultured with the presence of different concentrations (0,1,5,10,25,50,100 ng/ml) of recombinant TNF-α,curcumin of 20 μmol/L,or the combination of recombinant TNF-α (25 ng/ml) and curcumin (20 μmol/L),for 24 hours followed by the determination of cell proliferation with methyl thiazolyl tetrazolium (MTT) assay.Western blot was conducted to measure the protein expression of proliferating cell nuclear antigen (PCNA) and Notch-1 in HaCaT cells treated with recombinant TNF-α (25 ng/ml) and curcumin (20 μ mol/L) alone or in combination for 24 hours.Flow cytometry using annexin-V/propidium iodine (PI) was performed to assess the early apoptosis in HaCaT cells incubated with recombinant TNF-α of 25 ng/ml and curcumin of 20 μmol/L alone or in combination for 12 hours.Statistical analysis was carried out with one-way analysis of variance.Results Recombinant TNF-α promoted the proliferation of HaCaT cells in a dose-dependent manner,with the maximum proliferation activity observed in HaCaT cells treated with TNF-α of 25 ng/ml,while curcumin of 20 μmol/L effectively inhibited the proliferation of HaCaT cells induced by TNF-α of 25 ng/ml (P ＜ 0.01).TNF-α of 25 ng/ml had no obvious effect on cell apoptosis,while curcumin of 20 μ mol/L markedly induced the apoptosis in HaCaT cells,and there was a synergy between TNF-α of 25 ng/ml and curcumin of 20 μmol/L in the induction of apoptosis in HaCaT cells,with the apoptosis rate being 2.3％,3.4％,11.6％ and 16.8％ respectively in untreated cells,cells treated with TNF-α,curcumin,and the combination of TNF-α and curcumin,respectively.Conclusions Curcumin could enhance the inductive effect of TNF-α on the apoptosis in,but suppress the promotive effect of TNF-α on the proliferation of,HaCaT cells.

The key treatment for overlap syndrome should focus on maximizing the therapeutic effect of each condition and concentrate of interventions that have showed benefit in both diseases. The goal of therapy includes the improvement in objective data including the reduction in sleep fragmentation, exacerbation rate, hospitalization frequency and mortality, and subjective data such as daytime functioning, quality of life and sleep quality. At present, the treatment of overlap syndrome is mainly rely on the positive airway pressure to improve ventilatory capacity and gas exchange function. Oxygen therapy as auxiliary treatment can alleviate hypoxemia. The key of drug therapy is to dilate the bronchus, clear secretions, reduce in?flammatory response to improve the ventilation function. Meanwhile, daily exercise and dietary habits of life activity are indis?pensable in the treatment of the disease as important supporting role to improve the motor function and the quality of life in patients.
