BACKGROUND: The proliferation and differentiation of mesenchymal stem cells (MSCs) lack of regulatory functions. Following combining with suitable vectors, MSCs cannot highly effectively proliferate and differentiate, which are keys to prevent MSCs entering the clinic. It is of great importance to effectively regulate the differentiation of stem cells into osteoblasts using pulse electromagnetic field.OBJECTIVE: To investigate the differentiation of mouse MSCs into osteoblasts in vitro following stimulation of pulse electromagnetic field.DESIGN, TIME AND SETTING: The cytological in vitro controlled study was conducted at the Laboratory of Department of Orthopaedics, Puai Hospital of Tongji Medical College, Huazhong University of Science and Technology from May 2004 to October 2007.MATEIRALS: Totally 20 BALB/C mice were supplied by the Experimental Animal Center of Tongji Medical College. Pulse electromagnetic field deviser was designed and made by the Department of Electric Machine, Naval University of Engineering.METHODS: Mouse bilateral femur was sterilely isolated. BMSCs were harvested by the Percoll density gradient centrifugation,and purified and proliferated by the adherent method. Cells at the third passage (2×10~7/L) were incubated in a 6-well plate, and then divided into 4 groups. Cells in the blank control group were incubated in the complete medium. Cells in the pulse electromagnetic field underwent pulse electromagnetic field radiation of 50 Hz, sinusoidal wave, and 1 mT, twice a day, once 30 minutes, with an interval of 12 hours, totally 10 days. Cells in the osteogenic induction group were incubated in the complete medium, supplemented with dexamethasone, sodium glycerophosphate and VitC. Cells in the pulse electromagnetic field + osteogenic induction group were subjected to the same pulse electromagnetic field radiation and then incubated in the complete medium.MAIN OUTCOME MEASURES: The differentiation of BMSCs was measured.RESULTS: Results of alkaline phosphatase staining showed that cells were negative in the blank control group, but weakly positive in the pulse electromagnetic field group, positive in the osteogenic induction group, and strongly positive in the pulse electromagnetic field + osteogenic induction group 10 days following intervention. Compared with the blank control group,absorbance value of type I collagen immunohistochemistry was significantly greater in the osteogenic induction group, pulse electromagnetic field + osteogenic induction group (P < 0.05, P < 0.01).CONCLUSION: Pulsed electromagnetism fields of 50 Hz, waves of sine, with the intensity of 1 mT could promote alkaline phosphatase and type I collagen expression and enhance the differentiation of mouse BMSCs into osteoblasts in vitro.

Radiation-induced lung injury (RILI) is a common complication in thoracic cancer patients through radiotherapy, which can be divided into the early-stage radiation-induced pneumonitis (RP) and late-stage radiation-induced lung fibrosis (RILF). At present, glucocorticoids are mainly adopted in the clinical treatment of RP. However, there has been no effective medical treatment for RILF. RILF patients will eventually die from respiratory failure. The exact mechanism of RILI remains unclear. Current studies have proposed that its possible pathogenesis might consist of genetic heterogeneity, oxidative stress and cell damage. In this review, studies related to the pathogenesis of RILI were summarized.

It is difficult for medical students to understand electrocardiogram theory. The sec-ond clinical medical college of Wuhan University has explored clinical pathophysiology and therapy (CPPT) pattern in electrocardiogram education. Basic medical knowledge and clinic medical knowl-edge are combined with electrocardiogram theory to reinforce students ' comprehension and attract theit interest in order to obtain better teaching effect. Drawing themselves, analyzing electrocardiogram sys-tematically and memorizing theory with figure is aimed at solving forgetful problems. In addition, the problems such as lack of conformable teaching material, professional teaching teams and objective mode of examination are raised, and the solutions are explored under CPPT pattern.

Aim To study protective effects of Total of flacone C(TFC) against cerebral ischemia-reperfusion injury.Methods Four-vessel occlusion method was used to make acute cerebral ischemia-reperfusion model. Rats were initiated by ischemia for 30 min followed by 40 min of reperfusion.The electroencephalography(EEG) during cerebral ischemia and reperfusion was recorded.The level of intracellular calcium ion concentration([Ca~(2+)]i) in cerebral cells after ischemia was measured by using a Ca~(2+) indicator Fura-2/AM.Superoxide dismutase(SOD),Glutathione peroxidase(GSH-Px),Lactate dehydrogenase(LDH),nitric oxide Synthase(NOS) activeties and Malondialdehyde(MDA),Nitric Oxide(NO)contents in the ischemia cerebral cortex were measured.Results TFC can improved the EEG change,significantly attenuated the decrease of the intracellular calcium ion concentration([Ca~(2+)]_i), remarkly increased GSH-Px,SOD and NOS activities in the cerebrum,inhibit the decrease of LDH activity and NO,MDA contents.Conclusion TFC has protective effects on cerebral ischemia-reperfusion injury,the mechanism may be related to attenuating free radical,[Ca~(2+)]i overload and NO.

Background Aheration of eyeball wall caused by ocular axial extension is associated with multiple complications of high myopia.However,the study on quantitative analysis of choroidal thickness and axial length in adult high myopic patients is less.Objective This study was to investigate the choroidal thickness in high myopic eyes of adult patients and estimate the correlation of choroidal thickness with axial length,age,and spherical equivalent(SE).Methods A prospective cohort study was designed.Seventy-five eyes of 75 adult patients with high myopia were entrolled from December 2012 to May 2013,and 70 eyes of 70 age-and gendermatched healthy volunteers were included in Renmin Hospital of Wuhan University.Enhanced depth imaging (EDI)on Cirrus spectral-domain optical coherence tomography (SD-OCT) was used to measure the choroidal thickness from the outer border of the retinal pigment epithelium through the inner scleral boarder among the 11 meridians in a 500 μm intervals and range of 2 500 μm for each from fovea toward temporal and nasal lateral.The differences of choroidal thickness and axial length were compared between the high myopia group and normal control group,and the correlation of choroidal thickness with axial length,age,SE were analyzed.Results The subfoveal and mean choroidal thickness values were (146±52) μm and (142±63) μm in the high myopia group,and those in the normal control group were (306±60) μm and (271 ±71) μm,with significant differences between the two groups (t =-17.130,P=0.000; t=-15.890,P=0.000).Choroid was thickest in the temporal and then was subfovea and nasal in the high myopia group,but in the normal control group,it was subfovea,temporal and nasal in turn,and the choroidal thicknesses in various areas were thinner in the high myopia group than those in the normal control group.A negative correlation was found between the choroidal thickness and axial length in high myopia group(r =-0.580,P =0.000),and the regression equation determined a decrease of 17.943 μm per millimeter of axial length.Conclusions SD-OCT determines that choroidal thickness is decreased in highly myopic eyes compared with normal eyes.Choroidal thickness varies with the change of axial length in adult high myopia patient.These findings indicate that abnormalities of the choroids may play a role in the pathogenesis of complication of high myopia.

BACKGROUND: Total flavone of ginkgo biloba(TFG) can affect on free radical, but the effect on apoptosis induced by cerebral ischemia is unclear.OBJECTIVE: To study the inhibitory effect of TFG on apoptosis induced by cerebral ischemia.DESIGN: Completely randomized controlled experimental study based on experimental animals.SETTING: Department of pharmacology in a university.MATERIALS: Totally 24 SD rats in half genders with clean grade and body mass of(250 ± 50) g, were divided into 4 groups at random: sham-operation group, model group, TFG 40 rmg/kg group and TFG 80 mg/kg group (Certificate No. 01).METHODS: This study was completed in the Department of Pharmacology,Anhui Medical University during October 2001 and January 2002. Incomplete cerebral ischemia was made by ligating bilateral common carotid arteries(CCA) in rats. The cerebral injury was evaluated by brain edema. The apoptosis was determined by terminal deoxy-nucleotidyl transforase-mediated dUTP-digoxigenin nick end-labeling(TUNEL) and transmission electron microscopy (TEM) method. The DNA fragmentation analysis was measured with the diphenylamine reagent method.MAIN OUTCOME MEASURES: Major factor: Effect of TFG on ultrastructral alteration of apoptotic cerebral cortex cells; Secondary factor: Effect of TFG on DNA fragmentation induced by cerebral ischemia.RESULTS: Ligating of bilateral CCA markedly induced apoptotic cell in cerebral cortex. TFG 80 mg/kg significantly inhibited brain edema( P ＜ 0.05 )and decreased the numbers of apoptotic cells in cortex( P ＜ 0.01 ) and improved ultrastructral alteration of apoptotic cells; TFG 40, 80 rmg/kg also inhibited the increase of DNA fragmentation induced by cerebral ischemia (P ＜0.05, P ＜0.01).CONCLUSION: TFG has inhibitory effect on ischemia-induced apoptosis of cerebral cortex and improve the ultrastructual changes of apoptosis. Moreover,TFG can relieve the occurrence of edema of ischemic brain tissue and inhibit the increase of DNA section induced by cerebral ischemia.
