Epidemiological and pathological evidence has demonstrated that adverse in utero environment,such as protein restriction,hypercholesterolemia,diabetes and smoking,can increase the risk of vascular disease in the offspring.In utero,the placenta and fetus are exposed to the metabolic,antioxidant and pro-inflammatory and anti-inflammatory signals from the mother and likely to make specific responses,which may lead to permanent changes either in DNA methylation or chromatin modification or both,and these changes,in turn,may result in increased atherosclerosis susceptibility in adulthood.In this review,we briefly summarize the possible signals crossing the placental barrier and discuss the molecular mechanisms of epigenetic programming in the developing fetus that may lead to increased athero-susceptibility of the vessel wall.

Objective To report the experience of the revision procedure with morselized bone grafting and a special design of acetabular prosthesis with three wings for loosened acetabular component in our hospital. Methods Since December 1989 to Junanry 1999, 23 cases with loosened acetabular component and bone defect were revised by morselized bone auto/allografting. There were 12 males and 11 females, the average age of the patients was 54.2 years old (range from 38 to 71 years old). The prosthesis of primary THA was double cup in 4 cases, the conventional THA in 19 cases, cemented in 22 cases and cementless in 1 cases. The severity of acetabular component loosening was classified into four types according to Gustillo: Type II in 3 cases, type III in 9 cases and type IV in 11 cases. The morselized bone autografting and allografting with size 4－ 6 mm were used in 6 cases and in 17 cases respectively. Different acetabular components had been used, the thread metal acetabular cup in 2 cases, screw fixed conventional metal acetabular cup in 10 cases and special design acetabular prosthesis with three wings in 11 cases. The latter prosthesis consists of an conventional acetabular component with pearl porous surface and three wings with different length and sharp edge distributed centrally in the superior lateral quadrant on the surface, the liner is made of UHMPE. Results No infection of the wound occurred in this group. The mean time of follow- up was 3 years and 8 months. Except 3 cases, all of the bone grafts was healed well and X－ ray showed that the containing of acetabular component was good, no translucent line between donor bone bed and prosthesis, and the bone defect had been repaired. The average Harris score was 47 before revision, and 86 after revision. The successful rate of revision was 86.9％ . There were 3 loosening cases postoperatively, 2 cases were due to incorrect position of prostheses and insufficient bone graft, another case was due to the screw being too short to fix the acetabular component. However, all of the three cases have partial bone growth in the original loosening acetabular. Conclusion 1. Direct contact between the morselized bone auto/allograft and the surface of metal acetabular component and the firm fixation of the prosthesis have showed good result of bone defect reconstruction. 2. The special design of acetabular prosthesis with three wings could be selected as an alternative method for huge bone loss of acetabulum (ranged from 64 to 79 mm), because it was able to enlarge the volume of the acetabular component.

Objective To explore the practical method and teaching effect of problem-based learning (PBL) pattern in teaching of gastrointestinal disease for seven-year-program students during their internal medical probation.Methods The traditional pattern (gastrointestinal diseases) and PBL pattern (hepatobiliary diseases) were applied in these students to assess the teaching effects by exam scores and questionnaire.Results ① There was no significant difference between traditional training and PBL by exam scores (P＞0.05).② The PBL approach was widely accepted by students,which could contribute to the improvement of their learning motivation.It developed skills,including self-directed learning,summarizing,and clinical thinking capability and so on.Conclusion The PBL approach is a practical learning strategy that can improve the teaching effect; therefore it should be wildly practiced in future works.

ObjectiveTo study the clinical effect of treating acute exacerbation of chronic respiratory failure with Danhong injection.MethodsAccording to random number table,64 cases of acute exacerbation of chronic respiratory failure were divided randomly into 2 groups,with 32 cases in each group.Both groups were given correspondingly conventional symptomatic treatment(including oxygen,anti-inflammatory,antispasmodic,sputum,etc.).On this basis,the treatment group was added Danhong injection 30 ml+5％glucose infusion 250 ml,once a day,continuous therapy for 14 days.ResultsThe total effective rate was 87.50％ and 65.63％ in Danhong injection treatment group and conventional treatment group respectively,showing obvious difference between 2 groups (x2=4.267,P＜0.05).The blood low shear viscosity (7.11 ± 1.60) mPa ? s,high shear viscosity of whole blood (3.30 ± 0.83 ) mPa ? s,plasma viscosity ( 1.28 ± 0.32) mPa ? s,whole blood reduced viscosity ( 16.81 ± 3.32 ) mPa ? s,erythrocyte aggregation index ( 1.26±0.31 ),erythrocyte deformation index (0.64±0.27) in the Danhong injection treatment group all had statistical significance compared to the conventional treatment group(P＜0.05).ConclusionClinical efficacy and safety of Danhong injection in treating acute exacerbation of chronic respiratory failure were good.

Objective To evaluate the effects of leg ischemic postconditioning on focal cerebral ischemia-reperfusion (I/R) injury in diabetic rats. Methods Forty male diabetic SD rats weighing 270-320 g were randomly assigned to one of 4 groups (n=10 each):group Ⅰcontrol (C);group Ⅱ sham operation (S);group Ⅲ fecal cerebral ischemia-repertusion (I/R) and group Ⅳ leg ischemic postconditioning (IPC). Diabetes mellitus was induced by intraperitoneal streptozotocin. Local cerebral I/R was produced by middle cerebral artery occlusion (MCAO) for 1.5 h followed by 6 h reperfusion. A nylon thread with rounded tip was inserted into internal carotid artery and threaded cranially until resistance was felt. Leg isebemia was induced by placing tourniquet on beth legs at 30 min before repeffusion. The animals underwent 3 episodes of 5 min leg ischemia at 5 min intervals. Neuro-functional deficit was assessed and recorded at the end of 6h reperfusion using neurologic deficit scores (NDS) (0=no deficit, 4=unable to crawl and semiconscious). The animals were then decapitated and their brains were removed for determination of volume of cerebral infaret (by TIC staining) and ratio' of neuronal apoptosis (by TUNEL). Results NDS and cerebral infarct volume were significantly increased at the end of 6 h reperfusion in group I/R and IPC as compared with group C and S. IPC significantly decreased cerebral infarct volume and ratio of neuronal apoptosis induced by MCAO. There was no significant difference in NDA between group I/R and IPC. Conclusion Leg iscbemic postconditioning can protect the brain against focal cerebral I/R injury in diabetic rats.

Objective　To study the possibility of measuring health status for residents in rural areas by the Chinese SF-36 scale. Methods　Health status for 207 residents in rural areas of Fuyang city who were 14 years old and over was measured by the Chinese SF-36 scale. The reliability and validity were analyzed. Results　The internal consistency reliability coefficients (Cronbach'α) exceeded 0.50 for all scales except SF and RE scales. Inter-scale correlation coefficients were lower than Cronbach'α coefficients for all scales except SF scale. Factor analysis identified three principal components, which could be used to explain 64.6% of the total variance. The differences of scale scores between the young group and the middle age group weren't significant. There weren't significant differences of scale scores between sexes except RP scale. The differences of scale scores between smokers and no-smokers, drinkers and no-drinkers weren't significant. Nor were the differences between various educational levels. Conclusion　Whether the Chinese SF-36 scale is suitable for measurement of health status for residents in rural areas needs further studies to give more evidences.

Objective To observe the effect of electroacupuncture(EA) on the expression of glucose transporter-1(GLUT-1) of hippocampal microvascular endothelial cells in focal cerebral ischemia(CI) rats.Methods Sixty male Wistar rats were randomly divided into sham-operation,model and electroacupuncture(EA) groups.CI model was established by middle cerebral artery occlusion with a piece of thread embolus.EA(4 Hz/20 Hz,1 mA) was applied to bilateral "Neiguan"(PC 6) for 30 min,once daily for 15 days.GLUT-1 expression in the hippocampus was detected with immunohistochemistry and Western blot,respectively.Results After the treatment,compared with the sham-operation group,the expression of GLUT-1 in microvascular endothelial cells of the hippocampus in model group shown by both histochemical and Western blot techniques decreased apparently(P
