Objective To study the changes of adriamycin-induced glomerular epithelial cells (GECs) permeability and cytoskeleton, and to explore the role and possible mechanism of epithelia growth factor (EGF) on adriamycin-induced glomerular epithelial barrier function. Methods Rat GECs on Milicell-PCF Inserts were exposed to adriamycin (0.5 ?mmol/L) 24 hours in the absence or presence of EGF. The paracelluar permeability to BSA and cell viability were evaluated. The expression of F-actin and alpha-actinin were analyzed by immunofluorescence and Leica laser scan confocal microscopy. Results After induced by adriamycin for 24 hours, paracelluar permeability to BSA and F-actin reorganization rate increased. Disassembling of cortical cytoskeleton architecture was observed. Stress fiber in cytoplasm disappeared. Alpha-actinin staining showed perinuclear enhancement, which is different from normal cytosolic pattern. EGF significantly reduced adriamycin induced effect. Higher level of BSA passed through GEC monolayer in a dose-dependent manner. EGF prevented adriamycin-induced cytoskeletal reorganization. Disassembled cortical cytoskeleton was recovered, and stress fiber appeared again. Alpha-actinin staining mainly exhibited cytosolic uniform distribution as control GEC. In addition, administration of either AG1478, a specific inhibitor of EGF-receptor tyrosine kinase, or U73122, a specific inhibitor of PLC? before EGF treatment attenuated the EGF-mediated effect, whereas neither AG1478 nor U73122 exerted influence in the absence of EGF. Conclusions Adriamycin increases GEC paracellular permeability to BSA as a result of adriamycin-induced cytoskeleton disassembling and disruption. EGF may prevent adriamycininduced cytoskeleton reorganization and maintain glomerular epithelial barrier function through EGF mediated EGF-EGFR-PLC? signal pathway.

Objective: To learn the health literacy status, trend and associated factors of Ningbo residents from 2015 to 2019, so as to provide basis for developing health policies and interventions. Methods: The monitoring data of health literacy of Ningbo residents from 2015 to 2019 was collected. The health literacy level was calculated and standardized by the population data of the sixth national census of Ningbo in 2010; five-year absolute growth and growth rate were used to reflect the changing trend. Multivariate logistic regression model was employed to analyze the influencing factors for the health literacy level. Results: The health literacy levels from 2015 to 2019 were 15.44%, 21.73%, 22.41%, 27.60% and 30.03%, with an annual increase trend ( P<0.05 ). The five-year absolute growth and growth rate were 14.59% and 94.49%. The Results of multivariate logistic regression analysis indicated that the year ( OR=1.158, 95%CI: 1.132-1.184 ), age ( 25-<35岁 years, OR=1.235, 95%CI: 1.039-1.468; 35-<45岁 years, OR=1.416, 95%CI: 1.193-1.681; 45-<55岁 years, OR=1.221, 95%CI: 1.024-1.455 ) , education level ( primary school, OR=1.790, 95%CI: 1.461-2.195; junior high school, OR=2.574, 95%CI: 2.102-3.154; high school/vocational high school/technical secondary school, OR=4.863, 95%CI: 3.943-5.998; college or above, OR=8.829, 95%CI: 7.109-10.965 ) , urban areas ( OR=0.934, 95%CI: 0.874-0.998 ) and occupation ( farmers, OR=0.692, 95%CI: 0.608-0.787; workers, OR=0.746, 95%CI: 0.664-0.837; enterprise staff, OR=0.822, 95%CI: 0.745-0.906; others, OR=1.106, 95%CI: 1.009-1.211 ) were the influencing factors for health literacy level. Conclusion The health literacy level of Ningbo residents shows an upward trend from 2015 to 2019, which are associated with age, education level, area and occupation.

Objective To investigate the role of phosphatidyl-inositol 3-kinase-Akt (PI3k-Akt) signal pathway in the attenuation of ischemia-reperfusion (I/R) injury by sevoflurane preconditioning in isolated rat hearts. Methods Ninety-six adult male SD rats weighing 220-280 g were randomly divided into 6 groups ( n = 16 each): sham operation group (group S); I/R group; sevoflurane preconditioning group (group SP); wortmannin group (group W); dimethyl sulfoxide (DMSO) group (group D) and sevoflurane preconditioning + wortmannin group (group SW) . Their hearts were excised and perfused in a Langendorff apparatus with K-H solution saturated with 95%O2-5%C02 at 37 ℃ . The hearts were continuously perfused for 180 min in group S. After 15 min of equilibration, the isolated hearts were subjected to 30 min of ischemia followed by 120 min of reperfusion in SP, W, D and SW groups. Croups SP, W, D and SW received 10 min of perfusion with K-H solution containing 2. 4% sevoflurane, 100 nmol/L wortmannin, 20 μmol/L DMSO, and 2.4% sevoflurane + 100 nmol/L wortmannin, respectively, followed by 5 min washout before I/R. Eight hearts in each group were selected and HR, left ventricular end-diabetic pressure (LVEDP), left ventricular developed pressure (LVDP), and ± dp/dtmax were recorded at the end of equilibration and at 15 min of reperfusion, Myocardial tissues were obtained at 15 min of reperfusion for determination of apoptosis (by TUNEL) and phosphorylated Akt (p-Akt) expression (by Western blot) . Another 8 hearts were selected at 120 min of reperfusion for determination of myocardial infarct size by TTC staining. Result Compared with group S, LVDP and ± dp/dt,^ were significantly decreased and LVEDP was significantly increased in groups I/R, SP, W, D and SW, and myocardial p-Akt expression was up-regulated in groups I/R, SP and D ( P ＜ 0.05). Compared with group I/R, LVDP and ± dp/dtmax were significantly increased, LVEDP and apoptosis index were significantly decreased, myocardial p-Akt expression was up-regulated, and myocardial infarct size was significantly reduced in group SP (P ＜0.05) . Conclusion Activation of PI3K-Akt signal pathway is involved in the attenuation of I/R injury by sevoflurane reconditioning in isolated rat hearts.

BACKGROUND: Bone marrow mesenchymal stem cell (MSC) is a kind of stem cell with potential of self-repair and multi-differentiation. It may differentiate into neuron, adipose cell and osteoblasts.OBJECTIVE: To observe the transforming efficacy of human bone marrow mesencymal stem cells (hMSCs) into neurons in vitro in different generations so as to provide reliable experimental data for the clinical application of MSCs.DESIGN: Single sample was designed.SETTING: Department of Neurology, Sino-Japan Friendship Hospital,Jilin UniversityPARTICIPANTS: Marrow tissue was collected from 9 cases of spinal fusion in Department of Orthopedics of First Hospital affiliated to Jilin University. Of 9 cases, all of them were in known of the experiment.METHODS: The experiment was performed in Sino-Japan Hospital affiliated to Jilin University from September 2002 to February 2003. The primary and generative culture of hMSCs was given. Experimental and the control groups were divided.-mercaptoethanol was taken as inducer. hMSCs of the 2rd, 4th, 6th and 8th generations were selected for induction in vitro for 6 h. Cytochemistry staining and immunohistochemistry staining were used to assay the expressions of neuronal and astrocytic marked proteins.MAIN OUTCOME MEASURES: ① Growth curve analysis on genera tive culture of hMSCs. ② Nissel staining. ③ Immunohistochemical staining.RESULTS: ① Common characters of generative culture: The latent phase of generative culture was 12-24 hours, exponential phase was 7-10 days and 11-13 days later, cell culture entered the platform phase. ② After induction of the 2nd, 4th and 6th generated hMSCs, deep blue granular Nissl body presented in cytoplasm. In 6 hours on the 8th induction, there was no obvious deep blue Nissl structure presented in cytoplasm.③ Except GFAP, NSE and NF-M were expressed in hMSCs of different generations after induction for 6 hours. There was no significant difference in positive rates of the 2nd, 4th and 6th generations (P ＞ 0.05), but the significant difference presented in comparison between the 8th generation and the 2nd, 4thand 6th generations (P ＜ 0.05). CONCLUSION:-mercaptoethanol can induce hMSCs differentiating into neuronal cells in vitro. The positive rates of the 2nd, 4th and 6th generationsare higher remarkably than the 8th generation.
