Objective To explore whether the inhibited expression of fibrocystin by RNA interference can increase epidermal growth factor (EGF)-induced cell proliferation and its possible mechanism . Methods A stable PKHD1-silenced HEK 293 cell line was established . Cell proliferation rate, intracellular Ca2+ concentration and extracellular signal-reguhted kinase 1/2(ERK1/2) activity were assessed after treatment with EGF, verapamil and Bay K8644 . Results The proliferation rate of PKHD1-silenced HEK-293 cells was found to be significantly higher after EGF stimulation compared to the control HEK 293 cell (231 .5% vs 152 .8%, P＜0 .01) . PKHD1-silencing lowered the intracellular Ca2+ concentration and caused EGF-induced ERK1/2 overactivation in the cells(P＜0 .01 ) . When cells were treated with verapamil for 4 hours to lower the intracellular Ca2+ concentration, the cell proliferation rate was significantly increased after 20 ng EGF for 24 hours . The verapamil treatment increased the level of activated ERK1/2 in EGF-treated cells . An increase of intracellular Ca2 + in PKHD1-silenced ceils repressed the EGF-dependent ERK1/2 activation and the hyperproliferative response to EGF stimulation . Conclusions Inhibition of fibrocystin can cause EGF-induced excessive proliferation through decreasing intracellular Ca2+ resulting in EGF-induced ERK1/2 activation . The loss of fibrocystin may lead to abnormal proliferation in kidney epithelial cells and cyst formation in ARPKD through modulation of intracellular Ca2+ concentration .

BACKGROUND: The coating induced by conventional simulated body fluid (SBF) and 1.5-folds SBF as biomimetic method has the shortcomings of slowly growth with weeks or months growth cycle. OBJECTIVE: To evaluate Ti-6Al-4V alloy surface deposition of hydroxyapatite coating induced by 3-folds SBF. DESIGN, TIME AND SETTING: In vitro biological analysis. The experiment was performed at the Institute of Metal Research, Chinese Academy of Sciences from November 2008 to March 2009. MATERIALS: Ti-6A1-4V alloy was supported by Boda Metel Materials Co., Ltd. METHODS: The pretreated Ti-6Al-4V alloy was immersed in 37 'C 3-folds SBF. The SBF was replaced every 24 hours for 3 days. MAIN OUTCOME MEASURES: The morphology, phase and elemental composition of calcium phosphate coating were analyzed by scanning electron microscopy, X-ray diffraction and infrared spectroscopy analysis. RESULTS: The scanning electron microscopy exhibited that the surface of Ti-6A1 -4V alloy was covered with deposited film with granular crystal on local areas at day 1 after immersion. The deposited film covered surface of Ti-6A1-4V alloy at day 3 after immersion, and granular or scale-shaped crystal could be seen. The crystal deposition displayed sustained growth with certain area as center. The product comprised Ca, P, O, C elements without Al, V. X-ray diffraction and infrared spectroscopy analysis revealed that the main component of the coating was hydroxyapatite. CONCLUSION: The 3-folds SBF can accelerate the deposition as well as shorten formation duration of hydroxyapatite coating on Ti-6A1-4V alloy.

BACKGROUND:At present, the study to balance ability of functional ankle instability patients is less. The
balance ability deficiency may also be one of the important reasons for ankle repeated injury, so the research can effectively reduce the damage probability.
OBJECTIVE:To explore the static balance ability characteristics of functional ankle instability patients.
METHODS:Ten male subjects with unilateral functional ankle instability were enrol ed as the experimental group in the study, and other 10 healthy match-paired subjects were served as the control group. Their static balance ability was measured under double feet standing and single foot standing using win-pod system, the double feet testing lasted for 30 seconds and the single foot testing lasted for 10 seconds. Evaluation parameters of balance ability were obtained.
RESULTS AND CONCLUSION:During double feet testing, there were no significant differences in balance
ability parameters between the experimental group and the control group whether eyes be opened or closed (P>0.05), but the index values of double feet testing were obviously less than those of single foot testing. So we
concluded that in the double feet standing, there was no significant difference in the static balance ability between functional ankle instability patients and normal persons. Moreover, the static balance ability of double feet was
better than that of single feet. In the single foot standing of the affected foot, the static balance ability of functional ankle instability patients was slightly worse than that of the normal persons, especial y with eyes closed.
Comparison of the average swing between the X-axis and Y-axis found that in the process of maintaining balance posture, the swing direction of the body center of gravity was mainly in the anteroposterior direction.

Objective To investigate the effect of ethyl pyruvate (EP) on the expression of caspase-3 in the hippocampus and the learn-ing and memory ability in neonatal rats with hypoxic ischemic brain damage (HIBD). Methods 90 Wistar rats of 7 days old were randomly divided into sham operation group (n=15), HIBD group (n=15), EP1 group (n=15, 10 ml/kg), EP2 group (n=15, 30 mg/kg), EP3 group (n=15, 50 mg/kg) and EP4 group (n=15, 100 mg/kg). The model was established with Rice's method. 30 minutes before operation, and every 24 hours after operation, EP groups were injected with 10 ml/kg, 30 mg/kg, 50 mg/kg, 100 mg/kg EP in abdomen respectively, for 2 weeks. Af-ter treatment, the caspase-3 positive cells were observed by immunohistochemical staining, and the latency and the times crossing the target quadrant were tested by Morris water maze test. Results The caspase-3 positive cells were less in EP groups than in HIBD group (P<0.05), expect EP1 group (P>0.05), especially in EP3 group (P<0.01). The latency and the times crossing the target quadrant were better in EP groups than in HIBD group (P<0.05), expect EP1 group (P>0.05), especially in EP3 group (P<0.01). Conclusion Ethyl pyruvate can de-crease the expression of caspase-3 in hippocampus, and improve the ability of memory and learning in neonatal rats with HIBD.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disorder of hematopoietic stem cells due to acquisition of somatic mutations.Somatic mutations in phosphatidylinositol glycan class A (PIGA) account for intravascular hemolysis and other PNH manifestations,but the pathophysiology of clonal expansion of PNH cells cannot be elucidated clearly.PNH is closely related to aplastic anemia and myelodysplastic syndromes.Today,the gold standard for PNH is flow cytometry to detect the absence or severe deficiency of glycosylphosphatidylinositol (GPI)-anchored proteins on white and red blood cells.However,PNH diagnosed by phenotype is a group of heterogeneous disease in pathogenesis.Eculizumab,a first-in-class monoclonal antibody that inhibits terminal complement,is highly effective in stopping intravascular hemolysis and improving quality of life.Further research on the pathogenesis of PNH would be helpful to understand the underlying reasons for PNH phenotype cells in different patients,improve differential diagnosis and more targeted and specific therapy.Research progress in recent years will be reviewed in this article.
