BACKGROUND:Epimedium has been used in the treatment of osteoporosis and repair of bone defects. OBJECTIVE:To explore the effects of epimedium on the osteogenic differentiation of bone marrow mesenchymal stem cells.
METHODS:A database search was performed to retrieve literatures addressing epimedium effects on the osteogenic differentiation of bone marrow mesenchymal stem cells. Then, the papers meeting the criteria were selected for in-depth analysis. During the osteogenic differentiation induced by epimedium, alkaline phosphatase, osteocalcin, osteopontin, transforming growth factorβ, bone morphogenetic proteins, osteocalcin, bone sialoprotein were detected in the bone marrow mesenchymal stem cells to understand the underlying mechanism of epimedium in proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells.
RESULTS AND CONCLUSION:Epimedium effects on bone marrow mesenchymal stem cells are shown in a dose-dependent manner. During the early induction, icari n can increase cellphosphatase activity;in the late induction, icari n can increase calcified nodules, promote osteocalcin secretion, significantly improve the expressions of transforming growth factorβ1, bone morphogenetic protein 2, insulin-like growth factor-1, osteopontin and bone sialoprotein. Epimedium, which can be used as an excellent osteoinductive factor, improves the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells.

BACKGROUND:Drug treatment is the main method for the treatment of diabetes currently, but the development of the disease and occurrence of related complications are the chal enges to the effect of drugs. OBJECTIVE:To investigate the effect and feasibility of co-transplantation of bone marrow mesenchymal stem cells and islet cells for the treatment of diabetes. METHODS:The rat bone marrow mesenchymal stem cells were separated and purified, and cultured in vitro to establish the diabetes models. The rat diabetes models were injected with bone marrow mesenchymal stem cells, co-cultured mixture of bone marrow mesenchymal stem cells and islet cells, and normal saline or phosphate buffer (control). The effect of transplantation was evaluated through observing the blood glucose levels, insulin secretion, and pathological changes of pancreatic tissue in the rat diabetes models. RESUTLS AND CONCLUSION:In the diabetes rats treated with bone marrow mesenchymal stem cel transplantation, the C-peptide levels were significantly increased after transplantation, while the blood glucose levels were significantly decreased, but not lower than the normal level, and the blood glucose levels were increased again with the time prolonging. In the diabetes rats treated with co-transplantation of bone marrow mesenchymal stem cells and islet cells, the blood glucose levels were decreased significantly and lower than the normal level which was maintained in a certain time, and the decreasing degree was larger than that in the rats treated with simple bone marrow mesenchymal stem cel transplantation. Co-transplantation of bone marrow mesenchymal stem cells and islet cells is feasible for the treatment of diabetes with a certain effect.

BACKGROUND:Diabetes mel itus is a common complication after kidney transplantation. OBJECTIVE:To investigate the risk factors for diabetes mel itus after kidney transplantation diabetes mel itus risk factors and clinical treatment based on integrative medicine. METHODS:Literatures concerning diabetes mel itus after kidney transplantation were retrieved in the database, and the articles that met the study criteria were analyzed. In this paper, we analyzed the risk factors for diabetes mel itus and concluded the therapies for diabetes mel itus after kidney transplantation. RESULTS AND CONCLUSION:Diabetes mel itus after kidney transplantation is an abnormal glucose metabolism caused by multiple factors, which is related to age, body mass index, lipid levels, immunosuppressant program, frequency of acute rejections, and cumulative dose of glucocorticoid. Periodic monitoring of blood glucose after kidney transplantation contributes to the earlier detection of the occurrence of diabetes mel itus. Integrative medicines that can lower blood glucose level and immunosuppressant adjustment can be effective for the treatment of diabetes mel itus after kidney transplantation.

OBJECTIVE To discuss the clinic presentation,imaging characteristics and surgical management of the external auditory canal cholesteatoma (EACC) with invasion of the tympaniccavity and the mastoid. METHODS This was a retrospective study including the clinical data of 14 cases of EACC invading tympanic cavity and mastoid from 1998 to 2003 . RESULTS All 14 cases showed different bone erosion in the four walls of external auditory canal with extention to the mastoid . Pars flaccida perforation were found in 4 cases with invasion of the cholesteatoma into the tympanic cavity, the ossicular chains were compressed or destroyed. The bony mastoid segment of facial canal was destroyed in 3 cases . Cerebral plate destruction and congenital stenosis of external auditory canal were found in one case respectively. According to the extent of disease, modified radical mastoidectomy was performed in 8 cases and radical mastoidectomy in 5 cases , meatoplasty in one case. The post-operative hearing of 10 cases with intact ossicula chains were normal.One case with compression,shift of ossicules also got normal audition after the operation. The hearing threshold of the air condition in 3 cases with ossicular disruptions got 15 to 20dB of improvement among the language frequency after reconstruction of ossicular chain. The 14 cases were followed-up from 18 months to 5 years and no recurrences were found. CONCLUSION The exact etiology of EACC still remains unclear. There is some difficulty in diagnosing external auditory canal cholesteatoma (EACC) invading the tympanic cavity and the mastoid because of its untypical clinic presentation . High-resolution temporal bone CT scan could help to find out the primary lesion and determine the range of the pathological changes, and choose the proper surgical approach.
