BACKGROUND: Similar to other prosthesis, metal-metal prosthesis would produce plenty of wear particles and metal ions, mainly presented as cobalt (Co~(2+)) and chromium (Cr~(3+)), which can lead to osteolysis, eventually, result in aseptic loosening. OBJECTIVE: To observe the effect of Co~(2+) and Cr~(3+) ions on the cells viability and expression of RANK in rats m0nocyte-macrophage cells (RAW264.7) in vitro. METHODS: Monocyte-macrophage cells (RAW264.7) were cultured in vitro, and then the cells were exposed to Co~(2+) and Cr~(3+) ions. The cell viability was assured by MTT test and the level of RANK Mrna was detected by semi-quantitative RT-PCR at different times. RESULTS AND CONCLUSION: Compared to the control group, MTT test demonstrated that Co~(2+) and Cr~(3+)ions could decrease the cell activity of monocyte-macrophage cells obviously. When the cells were exposed to Co~(2+) Cr~(3+) ions, compared to the control group, the Mrna expression of RANK of the metal ions group was increased at 12 hours (P < 0.05), reached its peak level at 24 hours (P < 0.05), and decreased at 48 hours than that of 24 hours (P < 0.05). The results revealed that metal ions have a cytotoxic effect on monocyte-macrophage cells, stimulate the expression of RANK, and have the potential of facilitating monocyte-macrophages cells transform into osteoclast-like cells.

OBJECTIVETo investigate the protective effect of progesterone against high intraocular pressure-induced ischemia-reperfusion (IR) injury.
METHODSTwenty-four SD rats were randomly divided into normal control, IR model, dimethyl sulfoxide (DMSO) solvent treatment group, and progesterone treatment group. In the latter 3 groups, retinal IR injury was induced by intraocular injection of saline. In the progesterone group, intraperitoneal injections of 4 mg/kg progesterone were administered 30 min before and 2 h after ischemia, and an equivalent volume of DMSO was used in the DMSO group. The content of malondialdehyde (MDA) and superoxide dismutase (SOD) activity were measured by spectrophotometer after the treatment, and the pathological changes of the retina were observed by transmission electron microscope and light microscope.
RESULTSSix hours after reperfusion, the content of MDA in the model group was significantly higher than that in the normal control group (P<0.01), but lower than that in progesterone treatment group (P<0.01); reverse changes in SOD activity was observed. In the model group, the inner nuclear layer and nerve fiber layer became thinner with obvious cellular pathologies including nuclear condensation, mitochondria vacuolization and endocytoplasmic reticulum swelling. Progesterone treatment markedly alleviated these pathologies in the inner nuclear layer and nerve fiber layer of the retina.
CONCLUSIONProgesterone offers protection of the retina against IR injury in SD rats by increasing SOD activity and decreasing MDA content in the retina.

ObjectiveTo observe right ventricle (RV) structure and function of New Zealand rabbits with chronic intermittent hypoxia (CIH) for short-term (0-8 weeks) by echocardiography. MethodsTwenty-four healthy male New Zealand rabbits were set up CIH animal model for 8 weeks. RV structure?s systolic and diastolic function were measured by conventional and tissue Doppler echocardiography at 0, 1, 2, 4, 6 and 8 week and one rabbit was sacriifced randomly for RV myocytes and pulmonary tissue pathology examination. RV structure and function parameters at 0, 1, 2, 4, 6 and 8 week were analyzed by mixed effects model analysis.ResultsRV structure variables: RV, RA at 8 week increased compared with those at 0 week, but had no signiifcant difference (P>0.05); RV systolic function variables:RVFAC at 8 week increased compared with those at 0 week (F=3.45, P<0.05), TAPSE at 4, 6, 8 week increased compared with that at 0 week (F=3.11, 3.41 and 3.86, all P<0.05), RVMPI at 4 week decreased compared with that at 0 week (F=3.46, P<0.05), recovered to baseline at 6, 8 week. Isovolumetric relaxation time (IRTc) corrected by heart rate at 1, 2, 4 week decreased compared with that at 0 week (F=3.15, 3.31 and 3.17, all P<0.05), recovered to baseline at 8 week, ET of PA at 1, 2 week decreased compared with that at 0 week (F=3.01 and 3.15, both P<0.05), recovered to baseline at 4, 6, 8 week, AT of PA at 1, 2, 4 week decreased compared with that at 0 week (F=3.13, 3.15 and 3.32, all P<0.05), recovered to baseline at 6, 8 week. RV diastolic function variables: isovolumetric contraction time (ICTc) corrected by heart rate at 2, 4 week decreased compared with that at 0 week (F=3.13 and 3.33,both P<0.05), E/E? at 1, 2 week decreased compared with that at 0 week (F=3.13 and 3.44,bothP<0.05), recovered to baseline at 4, 6, 8 week, E/A at 4, 6, 8 week increased compared with that at 0 week (F=4.01, 3.82 and 3.37, all P<0.05), E?/A? at 8 week increased compared with that at 0 week (F=3.81, P<0.05). The myocardial pathology showed that RV myocardial cell structure was normal at 4 week. Nuclei enlarged, stain darkened and some cytoplasms loosed when exposed to CIH for 8 weeks. The structure of lung tissues was normal when exposed to CIH for 4 weeks. Inflammatory cell inifltrated, capillary engorged as well as the wall of pulmonary arterioles thickened slightly at 8 week.ConclusionsRV diastolic and systolic function showed compensatory and structure was normal in early CIH (0-8 week). RV diastolic function compensated earlier than systolic function. IRT and ICT were sensitive indicators of RV systolic and diastolic function compensation.

This study was aimed to investigate the expressions of adhesion molecules such as CD54, CD49d and CD62L by CD34(+) cells sampled from different stages of bone marrow (BM) and peripheral blood (PB) before/after G-CSF mobilization and after transplantation through the direct labeling with three colour-immunofluorescence and flow cytometry, and to explore the differences in expression of adhesion molecules on CD34(+) cells from different origins and their clinical significance. Mononuclear cells collected from BM and PB before mobilization, after collection of stem cells and hematopoietic recostruction of BM at the end of transplantation were marked with CD54-FITC, CD49d-FITC and CD62L-FITC separately, as well as CD34-PE and CD45PerCE. 3-color fluorescene analysis was carried out by FACS. The expression differences of CD34(+) and adhesion molecules between BM and APBSC were compared. The results showed that expression differences of CD54, CD49d and cd62Lon CD34(+) cells belore mobilization, after collection and reconstraction of transplantation were not statiscally significant, the difference of CD54, CD49d and CD62L on CD34(+) between 1st and 2nd collections of hematopoietic stem cells also were not statiscally significant. In the collected APBSC, the expression level of CD34(+) CD49d(+) was significantly lower than those in BM before mobilization (P = 0.001). It is concluded that the method of chemotherapy combined with G-CSF mobilization can down-regulate CD49d expression in BM CD34(+) cells, thus can mobilize and move theirs into peripheral blood. After the reconstitution by transplantation, the expression of CD49d on CD34(+) cells tends to normal, the clinical significance needs to be elucidated by accumulation of much more cases.
