With the gradual transformation of the American medical model from biomedical medel to bio-psycho-social model,the advancement both in the medical security and service system,preventire medicine as well as the protection of environment have been emphasized,while the revolution of the medical education has been carried out according to the divemified requirements of the bio-psyeho-social model,and the focus of health care has been moved forward.

Invasive aspergillosis is one of common causes of death in patients with hematologic malignancies and bone marrow transplant recipients .The high mortality is due in part to difficulties in timelydiagnosis because signs and symptoms are often nonspecific or are attenuated as a result of medication such as corticosteroids.In addition to the profound and persistent net state of immunosuppression in patients who develop invasive aspergillosis,intrinsic or secondary antifungal resistanceand the toxicity may also account for high mortality.

Medical science is both scientific and humanistic,and medical humanities education is an ever-lasting theme.To enhance residents'health,a new health service reform is being carried out by the government to promote the transformation towards the bio-psycho-social medical model.Social reality,mental environment and social factors have significant effects upon health.To impart medical humanities knowledge and cultivate quality of humanities are the missions of higher education.Based upon the practice of medical humanities education in Sun Yat-sen University and the experience of developed countries and regions,and by elaborating the theory to deepen understanding of medical humanities the author is to deal with the real needs and to enhance educational effectiveness of countermeasures.

Objective Based on the technique of computer network communication,to design and construct a mini medical picture archiving and communication systems (mini-PACS) in radiological department.Methods Radiologic information networks were composed of Anke SCT scanner, GMS and SHIMADZU digital radioscopy, SGI picture workstation, laser film printer, Dell server and report terminal computers with DICOM 3.0. Mini-PACS was constructed with radiological networks mentioned above and local area networks (LAN) existing in our hospital. Network parameters were set and network communication software FTP2000 was used to transport data. Radiological diagnosis and report program was edited with Visual Basic 6.0 (VB6.0).Results Five functions such as image acquirement, data transport and share, data archiving, report and print, register and statistics could be realized by mini-PACS. The system was stable for about 2600 cases during 420 days and no obstacle could be found after simple maintenance.Conclusion The mini-PACS can realize the five functions. Mini-PACS is practical, stable, safe and easy to maintain. It playes an important role in economic management and scientific research.

objectives To provide the reference for the Research & Development departments of hospitals by analyzing the quantity of publications and their cited status for the top 20 hospitals in SCl and MEDLINE.and top 100 hospitals in domestic publications in 2006.Methotis The number of publications and their cited times for the first 20 hospitals in SCI and MEDLINE.and the top 100 hospitals in domestic publications in 2006 were analyzed with bibliometric analysis.Results In 2006.the average increased ratio of publications in SCI for top 20 hospitals was 47.58%.but the number of articles in MEDUNE WaS decreased.For top 100 hospitals.the increased number of domestic publications was 71.25,the number of cited publications WaS increased 160.14.Conclusions The SCI publications from top 20 hospitals increased sharply,but publicatiOils indexed by MEDLINE decreased respectively.

Taking into account the near infrared spectra(NIR) on numerous predictor variables with serious collinearity and having nonlinear quantitative relationship with the chemical compositions, a novel nonlinear partial least squares(PLS) approach, termed as Spline-PPLS, was constructed by combining the penalized partial least squares(PPLS) regression with B-splines transformation. Firstly, the observed spectral predictors were considered as discrete observations of curves of the wavelength and were nonlinearly transformed using B-spline basis functions. The choice of the degree of the polynomial pieces and of the number of knots was performed using the cross-validation strategy. Then, the PPLS algorithm was performed on the high dimensional transformed data matrix to build the calibration model by imposing a penalty term to the optimization criterion of PLS. The roughness penalty term indeed controlled the curvature of the functions and its smoothing parameter could also be obtained by the cross-validation. Finally, the proposed Spline-PPLS approach was applied to the wheat NIR diffuse reflectance spectra reconstruction and quantitative analysis. The result indicates that the Spline-PPLS approach not only can yield high accuracy reconstructing spectrum, but also improves the model prediction accuracy in the case of nonlinear relationships.

OBJECTIVE：Rare-earth compound was added to the medium of Ganoderma lucidum to study the effect of rare-earth elements on the hypha growth,the fresh and dry weight of fruit body of G.lucidum.METHODS:The culture medium dressed with rare-earth elements.RESULTS:It showed that all concentrations of rare-earth elements had some inhibition on the hypha growth of G.lucidum.However they could make the hypha of G.lucidumwhiter.The fresh and dry weight of fruit body increased significantly when the concentrations of rare-earth elements were 100μg.g-1 and 150μg.g-1.Their raising rates were +4.13%，+0.20% and +16.47，+5.84%respectively.CONCLUSION:The yield of G.lucidum can be increased by rare-earth elements when its concentrations were 100～150μg.g-1.

The pilot work urban workers medical network settlement of Anhui province has launched in full scale,effectively facilitating the population seeking medical service elsewhere.In this regard,the medical settlement of a pilot hospital is cited as an example to introduce the networked medical settlement in remote places,summarizing problems encountered,and coming up with proposals accordingly.

The family of bone morphogenetic proteins (BMPs) belongs to the superfamily of transforming growth factor-β (TGF-β). It has various functions in the body. In recent years the BMPs family(especially the BMP7) has been discovered to play an important role on the genesis and development of cancer. In this article the characteristic, the mechanism and the function of BMP7 in the genesis and development of cancer are summarized.
