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 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 .

This paper applied the Shannon Entropy based on the cross correlation to analyze the epicardial signals from anterior wall of the canine atria. The result demonstrated that during sinus rhythm, the stability level of the correlation among signals from anterior right atria is much higher than the signals from anterior left atria. All the signals from the anterior wall descended when the rhythm changed from sinus rhythm to atrial fibrillation(AF). However, there were some regions still having a stable correlation during AF. The results will be helpful to enhance understanding of the correlation characteristic of AF.

Objective The existing laryngoscope can not be used to observe the ultrastructure of cells.As a result,doctors always have to conduct biopsies on some patients who can not be diagnosed.The timeconsuming procedure of biopsy may be detrimental to the timely diagnosis and treatment.To solve this problem,we aimed to design the integrative confocal-microscopic hard laryngoscope system (ICMHL).Methods ICMHL system integrated the technique of existing laryngoscope and confocal microscopy,which allows doctors to observe the macrostructure and microstructure of lesions at the same time. Results With the effect of fluorescein sodium,ICMHL system could record the dynamic changes of cells at a rate of 30 fps,and the confocal-microscopic host machine could photograph images at a rate of 230 fps and diagnose invisible minute lesions.Conclusion ICMHL system provides a new,real-time approach for clinic biopsy.

Objective To explore the changes of the levels of IL-8,LTB4 and its function in invasion in patients with chronic obstructive pulmonary disease(COPD).Methods The concentrations of IL-8 and LTB4 in serum and sputum were determined with enzyme linked immunosorbent assay(ELISA)in 30 cases of patients with COPD in acute aggravating stage and paracmasis and in 20 cases healthy adults.Blood routines were detected in all obstructs.Results The concentrations of IL-8 in serum and sputum in acute aggravating stage were(181.41±18.49)ng/L and(74.03±20.64)ng/L,significantly higher than those in paracmasis and the reference group(152.33±17.48)ng/L and(42.30±14.99)ng/L,P＜0.05).The concentrations of IL-8 in serum and sputum in paracmasis were significantly higher than those in reference group[(52.75±13.79)pg/ml and(17.15±5.36)ng/L,P＜0.05].The concentrations of LTB4 in sputum in acute aggravating stage were(2300.91±496.01)ng/L,significantly higher than those in paracmasis and the reference group[(1884.14±651.37)ng/L,P＜0.05].LTB4 level in acute aggravating is not significantly different from those in paracmasis and the reference group[(1941.30±301.62)ng/L and(1880.77±302.11)ng/L,P＞0.05).Conclusion Both IL-8 and LTB4 play important roles in the coupe of inflammatory reaction of air passage of COPD.

Post-stroke depression (PSD) is a common complication of stroke. Its patogenesis is complex, mainly including the mechanisms of neurobiotogy and social psychology. So far, there has been no uniform conclusion both at home and abroad. Now it is considered that PSD is the results of comprehensive effect of various neurobiology and social psychology, and its onset is in accordance with the bio-psycho-social medical model.
