With the change of people's concept of marriage and family changes,the divorce rate of our country has presented an obvious rising tendency,thus students from divorced family have become a large group gradually.The study focuses on the passive effects that divorced family have on the interpersonal communication of student from these families and analyzes the reasons and puts forward the countermeasures of the problem.

0 05).Conclusion The distribution frequency of bb type of VDR genotypes in Han populations of China was more prevalent,followed by Bb and bb types in turn.In the patients receiving long term glucocorticoid therapy,there is no significant difference in BMD between Bb and BB genotypes.The data suggest that the VDR genotypes may not be a means to identify patients at great risk of glucocorticoid induced osteoporosis,which await to be further confirmed with a large sample size.

The effects of advanced glycation end-products (AGEs) on number and activity of vascular endothelial cells (VEC) from hone marrow stem cells (BMSC) of mice were investigated. 100 μ/ml AGEs markedly inhibited differentiation of BMSC into VEC with decreased vascular endothelial growth factor receptor-2 positive cells, hut 20 μg/ml AGEs had no effect.

Objective To observe the serum level of the CD62p,CD63 which indicates the platelet activity of the elderly patients treated by different-dose simvastatin after PCI.Methods Sixty-eight patients with acute coronary syndrome post PCI were randomly divided into 20 mg/d simvastatin group(36 patients)and 40 mg/d simvastatin group(32 patients).We examined the patient's blood CD62p,CD63 levels on the day before the treatment of PCI in both groups.Then all of the patients in both groups received different-dose simvastatin treatment(20mg/d or 40 mg/d qn po);we observed the results again after four weeks in both groups,and compared the results.Results The patients' blood CD62p,CD63 levels decreased significantly after the treatment of simvastatin in both groups(P

Objective:To construct the eukaryotic vector of human DC-SIGN and EGFP fusion protein,and to identify the protein in cell line COS7.Methods:RT-PCR,T-vector and pEGFP-C1 vector were used to construct the recombinant expressing plasmid encoding for the fusion protein of DC-SIGN and EGFP.COS7 cells were transfected with the plasmid.Real-time PCR and laser scanning confocal microscope were used to quantificate expression of the fusion protein and cell function of uptaking BCG.Results:DC-SIGN cDNA was successfully cloned into the eukaryotic vector pEGFP-C1.The recombinant vector was transfected into COS7,real-time PCR test showed the amount of mRNA encoding for the fusion protein was 4.52?1011 copies/ml and laser scanning confocal microscope confirmed that the cells could uptake BCG.Conclusion:We have constructed a recombinant vector expressing DC-SIGN and EGFP fusion protein.

Competition in the medical market in future will be the competition of core competence. Confronted with the increasing integration of the domestic and foreign medical markets, hospitals in our country will have no other strategic alternative but to devote major efforts to enhancing their core competence. After defining the concept of core competence of hospitals, the authors make an analysis of the features and elements of core competence of hospitals and put forward measures for enhancing the core competence of hospitals.

Starting from the brand new angle of exploring the interaction between the knowledge capital and the financial capital of the hospital, the paper presents the theoretical basis and practical significance of the interaction between the knowledge capital and the financial capital of the hospital. Moreover, by establishing tentative models of hospital capital operation and by making theoretical analyses into the interactive and incremental relationship between knowledge capital and financial capital by means of mathematical analysis and deduction, the paper further demonstrates that the interactive integration of the knowledge capital and the financial capital of the hospital is an important condition which ensures that the operation of the hospital will maintain a high momentum and its comprehensive competitiveness will continue to be in a power position.

BACKGROUND:Preliminary studies have showed that vacuum sealing drainage based on wound surface dressing biomaterials is a good method to cover the wound as succedaneous peau when the soft tissuedefects along with open fracture cannot be completely repaired during the first operation. OBJECTIVE:To explore the efficacy of vacuum sealing drainage based on wound surface dressing biomaterials in repair of soft tissue defects of foot and ankle. METHODS:Fourteen patients with soft tissue defects of foot and ankle were treated using free skin graft combined with vacuum sealing drainage technique. Meanwhile, the traditional skin graft after wound dressing changes was applied in another 11 patients. The clinical outcomes were compared between two groups. RESULTS AND CONCLUSION:The transplanted skin in 10 cases of the vacuum sealing drainage group survived. The total survival rate was 71%, and surgical dressing change was applied in the left four patients to finaly cover the wound. By comparison, the transplanted skin in four cases of the traditional group survived. The total survival rate was 54%. To finish the wound, three of the left patients were turned to surgical dressing change and two of them stil needed skin graft operation once more. The total survival rate between the two groups has no statistical significance(P > 0.05). The therapeutic procedure noted that the time waiting for the secondary surgical visit, times for dressing change before the second intervention and the time for final union between the two groups were statisticaly different (P < 0.05). So the vacuum sealing drainage based on wound surface dressing biomaterials may accelerate the repair of soft tissue defects of foot and ankle when using the free skin graft operation.

Objective To develop a new methodology of prenatal sonography scoring to assess and dignose clubfoot.Methods Thirty-one fetuses suspected clubfoot(50 foots) and 62 normal fetuses(124 foots) were scanned with both 2D and 3D sonography,and were divided into normal feet group and clubfeet group.Our scoring system was made according to the Pirani-scoring for children,while considering the morphology of mid-foot and hind-foot of infants.The doctors would give final diagnosis for all fetuses after delivery or induced labor,and analyse the correlations among the abnormal signs,sonographic score and the clinical outcomes.Results The curve lat border,the medial crease,the empty heel and the post crease can be observed in the 3D reconstruction images.These four abnormal signs had close correlations with the clinical results.Conclusions The new prenatal clubfeet scoring system by 3D sonography is a promising methodology with clinical values.

The risk of stroke increases significantly after transient ischemic attack (TIA). TIA is an independent risk factor for cerebral infarction. This article review s the advances in prediction models of stroke risk after TIA in order to conduct rapid and accurate risk assessment and stratification in patients w ith TIA and develop timely reasonable treatment strategies, thereby reducing the risk of stroke.
