Universal health has been highly valued by the public and the government,and medical science and technology have been much improved.However,these are accompanied by a complex situation of doctor-patient relationship.We discuss here that humanism be fostered in medical education and clinical practice.A harmonious doctor-patients relationship can be maintained only when patientcentered medical service is applied and humanistic care is integrated but not overly dependent on technology and seeing patient as mere cases.

Traditional teaching plays a major role in pre-clinical genetics teaching,but the PBL teaching mode greatly mobilizes the enthusiasm of students in clinical genetics teaching. However reasonably and scientific combination between traditional teaching and PBL teaching contributes to more positive effect in medical genetics teaching.

Objective: To study the protective effect of the total flavones of buckwheat flowers and leaves (TFBFL)on the myocardial injury of the type 2 diabetic rats,and to clarify its mechanism.Methods:The diabetic rat models were established by intraperitoneally injecting streptozotocin (STZ)and taking high-fat diet.The model rats were divided into diabetic model (DM)group and TFBFL treatment (TFBFL)group,while normal control group was set up, 10 rats per group.The rats in TFBFL group were administered with 200 mL· kg-1 · d-1 TFBFL,while the rats in other two groups were given with normal water (10 mL·kg-1 ·d-1 )instead.The rats in various groups was administered once a day for 8 weeks.The body weight (BW),heart weight index (HWI), level of fasting blood glucose (FBG)and cardiac function indexes (HR,LVSP,LVEDP and ± dp/dtmax )of the rats in various groups were measured.The myocardial tissue morphology of the rats in various groups was evaluated by electron microscope and the collagen levels in myocardium tissue of the rats in various groups were observed by Masson staining.The expression levels of TGF-β1 protein in myocardium tissue of the rats in various groups were detected by Western blotting method.Results:Compared with normal control group,the HWI,FBG and LVEDP levels of the rats in DM group were increased (P <0.05 or P <0.01),and the BW, HR,LVSP and ±dp/dtmax level in DM group were decreased (P <0.05 or P <0.01).Compared with DM group,the FBG and LVEDP level in TFBFL group were decreased (P < 0.01 ),and the HR,LVSP and ± dp/dtmax level in TFBFL group were increased (P < 0.05 or P < 0.01 ); but the BW and HWI level in TFBFL group had no significant difference compared with DM group (P >0.05).The Masson staining results showed the morphology of myocardium tissue of the rats in TFBFL group was improved and the collagen level was decreased. The Western blotting results suggested that the TGF-β1 protein expression level in myocardium tissue of the rats in DM group was significantly increased compared with normal control group (P < 0.05),and the TGF-β1 protein expression level of the rats in TFBFL group was decreased compared with DM group (P <0.05).Conclusion:TFBFL exerts a certain protective effect on the myocardial fibrosis of diabetic rats through inhibiting the TGF-β1 expression in myocardium tissue.

Objective To evaluate the short-term effectiveness of Amplatzer device closure for congenital heart diseases.Methods Under X-ray fluoroscopy or/and transthoracic echocardiography(TTE),percutaneous puncture of the femoral artery or vein was conducted and the Amplatzer occluder was passed through the catheter.Effectiveness evaluation by transthoracic echocardiography,electrocardiography(ECG),and X-ray examination was applied at 24 hours,1 month,6 months,and every 1 year after the procedure.Results In 1 case of perimembranous ventricular septal defect(VSD),the detachment of the Amplatzer occluder to the arch of aorta was due to an inadequate small size.This patient was immediately operated with successful removal of the device through the femoral artery and later underwent a re-deployment of a larger-sized Amplatzer occluder closure successfully.The remaining 29 patients with atrial septal defect(ASD),patent ductus arteriosus(PDA),or perimembranous ventricular septal defect underwent a successful deployment of the Amplatzer occluder on one session without complications.The operation time was 20~90 min (38?16 min),the X-ray exposure time was 5~45 min(18?10 min),and the length of hospital stay was 3~7 days(4?2 days).Conclusions Amplatzer occluder transcatheter closure of congenital heart diseases has advantages of simplicity of deployment,good safety,and high success rate.This procedure is suitable for patients with secundum ASD,membranous VSD,and PDA.

Objective To examine the expression and clinical significance of E26 transformation specific-1 in premature rupture of fetal membranes. Methods Fetal membranes from 75 women in the following categories were analyzed for Ets-1 expression: preterm and term premature rupture of fetal membranes; 70 women (control group) with term cesarean sections and without complications. Ets-1 protein was localized with the use of immunohistochemical S-P method. Results Ets-1 protein was expressed in both the nucleus and cytoplasm of trophoblast of human fetal membranes, with more obvious expression in the nucleus. Ets-1 protein's expression was up-regulated in the trophoblast of fetal membranes with premature rupture, which differed significantly from the control group (P<0.05). Ets-1 protein's expression was up-regulated in the trophoblast of fetal membranes with preterm premature rupture, which did not differ significantly from the control group (P>0.05). Conclusion Ets-1 is expressed in human fetal membranes and its expression is up-regulated with premature rupture of fetal membranes, suggesting a role for Ets-1 in extracellular matrix remodeling of the membranes. This study provides an evidence to predict premature rupture of fetal membrances.

Objective To investigate the effect of resveratrol on the proliferation and invasion of human pancreatic cancer PANC-1 cells. Methods Five groups including blank control group, 0. 1% dimethylsulfoxide (DMSO) group and resveratrol groups (50, 100, 200 μmol/L) were established. The proliferation of PANC-1 cells was detected by MTT assay. The apoptosis and cell cycle change were analyzed by flow cytometry. The invasive ability of PANC-1 cells was observed with a Transwell cell culture chamber. The expressions of Bax, Bcl-2,matrix metalloproteinases 2 (MMP-2) and 9 (MMP-9) of the PANC-1 cells were assayed by real-time quantitative PCR and Western blot. All data were analyzed using the analysis of variance. Results ( 1 ) The inhibition rate of resveratrol on the proliferation of PANC-1 cells was 0 in the blank control group, 3.25% ±0.42% in the 0. 1% DMSO group, 13.23% ± 1.68% in the 50 μmol/L of resveratrol group, 42.25% ± 3.20% in the 100 μmol/L of resveratrol group, and 56.94% ±5.31% in the 200 μmol/L of resveratrol group. There was a significant difference in the inhibition rate among the five groups (F=460. 10, P<0.05). (2) The apoptosis rate was 0.05% ±0.03% in the blank control group, 3.39% ± 1.77% in the 0. 1% DMSO group, 6.92% ± 1.85% in the 50 μmol/L of resveratrol group, 19.05% ± 2.01% in the 100 μmol/L of resveratrol group, and 27. 17% ±6.43% in the 200 μmol/L of resveratrol group. There was a significant difference in the apoptosis rate among the five groups (F = 38.84, P < 0.05). (3) There was no significant effect of 0. 1% DMSO on the cell cycle of PANC-1 cells. The number of PANC-1 cells in the G0/G1 and S phase was increased. (4) The average number of invading PANC-1 cells was 61 ± 13 in the blank control group, 54 ± 13 in the 0. 1% DMSO group, 48 ± 15 in the 50 μmol/L of resveratrol group, 23 ±6 in the 100 μ mol/L of resveratrol group and 18 ±7 in the 200 μmol/L of resveratrol group. There was a significant difference in the number of invading PANC-1 cells among the five groups (F = 69.08, P < 0.05 ). (5) There were up-regulated mRNA and protein expressions of Bax and down-regulated mRNA and protein expressions of Bcl-2, and the expressions of MMP-2 and MMP-9 of the PANC-1 cells were inhibited in the resveratrol groups. The changes of the protein expressions of Bax, Bcl-2, MMP-2, MMP-9 were consistent with the changes of the mRNA expressions of the four indexes. Conclusion Resveratrol can significantly inhibit the proliferation and invasion, as well as induce apoptosis of PANC-1 cells in vitro.
