Objective To investigate the autophagy effect and the crosstalk with apoptosis by UV in A375 cells.Methods GFP-RFP-LC3 lentivirus were used to evaluate the effect of autophagy after being irradiated with UV of different doses (0、10、30、50 mJ/cm2).After being treated with 30 mJ/cm2 irradiation,the apoptosis rate of A375 with or without autophagy inducer was evaluated by annexin V-FITC/PI with flow cytometry.Western blot was used to distinguish the biomarker of autophagy (BECN,LC3) and apoptosis (Caspase 3,9).Results After being irradiated with 10 mJ/cm2 or 30 rnJ/cm2 UV,the autophagosome was observed at 6 h and rich at 9 h.However,the dots of autophagy had been abundant continually from 3 h with 50 mJ/cm2.The ability of inducing autophagy of UVB is stronger than UVA.UVA and UVB showed synergistic effect in autophagy with the dose of 30 mJ/cm2.The Caspase 3 and Caspase 9 proteins were downregulated after 30 mJ/cm2 UV irradiation with autophagy biomarkers increasing,whereas the apoptosis biomarkers were enriched with the inhibition of autophagy.Conclusions UV can induce autophagy with more significant effect of UVB.Autophagy paly protective role by delaying apoptosis after 30 mJ/cm2 UV irradiation in A375.

Objective To study the protective effect of resveratrol on endothelial cells injury induced by oxidized low-density lipoprotein (oxLDL) and its protective mechanism. Methods The injured model was established by endothelial cell treated with oxLDL. In the experiment, endothelial cell were cultured in vitro and divided into seven groups which were: control group; solvent (DMSO) group, oxLDL group, quercetin plus oxLDL group, Reseveratrol-L (0.5 mol/L), M(5 mol/L), H(50 mol/L) plus oxLDL group respectively. Endothelial cells were incubated with 200?g/ml oxLDL for 18 hours in the absence or presence of various concentrations of resveratrol and quercetin. The apoptotic index was detected by flow cytometric. Meanwhile, the content of Malondialdehyde (MDA), and the activity of SOD, GSHPX in the culture medium and homogenate of endothelial cells were measured. Results Incubation of endothelial cells with oxLDL for 18 h elicited a significant increase in the percent of apoptotic endothelial cells, in control group, the percent of apoptotic cells is 7.6?0.6, however in oxLDL group, it increased to 41.4?2.3, furthermore, oxLDL induced the increase of the contents of MDA, and accompanied by the decrease in the activity of SOD, GSHPX in the endothelial cells, the difference of was significant as compared with control group. Pretreatment of resveratrol with 0.5～50 mol/L decreased these oxLDL-induced changes, in Reseveratrol with 50 mol/L group, the percent of apoptotic cells decreased to 13.0?1.5, the difference of was significant as compared with oxLDL group (P

ObjectiveTo investigate the effect of follow-ups on medical compliance behaviors and quality of life of patients with gastroesophageal reflux disease (GERD).Methods One hundred GERD patients who were hospitalized in our department from June 2012 to June 2013 were divided into intervention group (n=50) and control group (n=50) according to the random number table. Both groups received the same drug treatment and conventional nursing during hospitalization.The control group received periodically outpatient follow-ups,while the intervention group received professional follow-ups by trained nurses after discharge from hospital. The compliance behaviors and quality of life in these patients were assessed and statistically analyzed after 6 months nursing intervention or outpatient follow-up.Results With the implement of follow-up in patients with GERD,the intervention group was better than the control group in compliance behaviors,including the decrement of smoking and drinking,strong tea,coffee,having midnight snack and spicy food (P<0.05),but there was no difference in the behavior of staying-up between the two groups.Concerning the quality of life,the intervention group was significantly better than the control group in the 6 items excluding the physical and physiological functions (P<0.05).Conclusion Professional follow-ups can improve compliance behavior and quality of life of GERD patients.

Objective To explore the role of 14-3-3σ in cell cycle arrest,proliferation inhibition of HaCaT cells after UVB exposure.Methods Crystal violet assay was used to determine the viable density of HaCaT,HaCaTKD cells after being irradiated with UVB of different doses (10,20,30,40,50,60 and 80 mJ/cm2) for 48 h.After HaCaT and HaCaTKD being treated with 30 mJ/cm2irradiation,cell growth and cell cycle distribution were detected by CCK-8 assay and PI staining combined with flow cytometry,respectively.Western blot was used to evaluate the protein expression of 14-3-3σ,Cdc2,Cdc25c and Cyclin B1.Results After 48 h,the survival rate of both HaCaT and HaCaTKD decreased in a dosedependent manner.Especially,HaCaTKD cells had drastically low proliferation rate compared with normal HaCaT at 10 mJ/cm2 (t =8.83-49.63,P ＜ 0.05).The proliferation rate of HaCaTKD cells was significantly lower than that of HaCaT cells (F =32.89,P ＜ 0.05).After treatment with 30 mJ/cm2 UV irradiation,the ability of proliferation in normal HaCaT cells was recovered after 24 h while there was no proliferation in HaCaTKD cells within 72 h after the same treatment.The distribution of cell cycle has little change in HaCaTKD (P ＞ 0.05).UVB treatment led to cell cycle arrest from 6 to 18 h in HaCaT cells(t =7.41,9.22,9.16,P ＜0.05)while no cell cycle arrest could be observed in the HaCaTKID cell.Western blot detection indicated that the expression of 14-3-3σ in HaCaT cells was upregulated(t =5.42-9.57,P ＜0.05)while the Cdc25c and Cyclin B1 proteins were downregulated in both HaCaT and HaCaTKD cells (t =3.95-11.21,P ＜0.05).Specifically,Cdc2 protein decreased in HaCaT cells(t =4.93-5.37,P ＜ 0.05)but there was no change in HaCaT~ cells.Conclusions 14-3-3σ protein affects the proliferation and cell cycle of HaCaT cells after UVB irradiation.14-3-3oσ co-activates the expression of Cdc2,Cdc25cand Cyclin B1 to mediate UVB-induced G2/M arrest in HaCaT cells.

Objective To evaluate the effects of the right stellate ganglion block on the expression of β3adrenoceptor (β3-AR) in rabbits with heart failure.Methods Forty-eight Japanese white rabbits of both sexes,weighing 2.5-3.0 kg,were randomly divided into 3 groups (n =16 each):sham operation group (group S),heart failure group (group HF) and right stellate ganglion block group (group RSGB).Heart failure was induced by occlusion of left anterior descending branch of coronary artery and confirmed by ultrasonic cardiography 4 weeks later.A PE-10 catheter was inserted into the right stellate ganglion for administration of drugs.0.25％ bupivacaine 2 ml was injected through the catheter once a day for 2 weeks in group RSGB,while the equal volume of normal saline was injected instead of bupivacaine in S and HF groups.The left ventricular end-diastolic diameter (LVEDD),left ventricular end-systolic diameter (LVESD),ejection fraction (EF) and left ventricular fractional shortening (LVFS) were measured at 1 day before ligation (T0),before catheter insertion (T1),before 8th administration (T2),and 1 day after the last administration (T3).Eight rabbits were sacrificed at T1 and T3 in each group and myocardial specimens were obtained from the apex of the left ventricle for determination of the expression of β3-AR by Western blot.Results Compared with group S,the LVEDD and LVESD were significantly enlarged and LVEF and LVFS were decreased at T1-3,and the expression of β3-AR was up-regulated at T1,3 in groups HF and RSGB (P ＜ 0.05).Compared with group HF,the LVEDD and LVESD were significantly decreased,LVEF and LVFS were increased,and the expression of β3-AR was significantly down-regulated at T3 in group RSGB (P ＜ 0.05).Conclusion The right stellate ganglion block can improve the cardiac function of rabbits with heart failure through down-regulating the expression of β3-AR in myocardium.
