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.

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.

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.

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.

Objective To explore the correlation between the parameters of ambulatory blood pressure monitoring (ABPM) and prostatic volume in elderly patients with essential hypertension.Methods The 131 elderly patients with essential hypertension from March 2007 to December 2009 were enrolled in this study, including 102 benign prostatic hyperplasia (BPH) patients and 29 nonBPH (NBPH) patients. All patients underwent ABPM and ultrasound examination of prostate.Prostatic volumes (PV) were calculated and were compared between BPH group and NBPH group.Correlation between parameters of ABPM and PV was analyzed. Results (1)The maximal mean artery pressure (MAPmax) at night was higher in BPH group than in NBPH group [( 104.7 ± 12. 0)mm Hg vs. (99.6± 10. 1) mm Hg, P= 0.039]. (2)There were correlations between PV and MAPmax in all-day (r=0. 184, P=0. 035), MAPmax at daytime (r=0. 183, P=0. 037), MAPmax at night (r=0. 181, P=0. 040), respectively. Conclusions MAPmax of ABPM may be associated with PV in elderly patients with essential hypertension.

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.

The choledocho-pancreatico-duodenal junc-tion is located at the central part of choledocho-pancreatico-duodenal region. During early embryogenetic stage, the primary duodenum develops from the end of foregut and the beginning part of the midgut. The dorsal pancreas, hepatic diverticulum and the ventral pancreas which arises from the basic part of hepatic diverticulum are growing and rotating following the duodenum. During the course, the formations of the choledocho-pancreatico-duodenal region and the central part of choledocho-pancreatico-duodenal junction are complete. The injuries in cho-ledocho-pancreatico-duedenal junction may be caused by metal probe or lithotomy forceps for exploring, dilatating the distal bile duct or taking out the stones from the bile duct. Even if the injuries of choledocho-pancreatico-duodenal junction are deve-loped in a limited scope of several centimeters, several adjacent organs may be involved. Injuries in choledocho-pancreatico-duo-denal junction are hard to be identified during operation and may develop into serious pathological procedures.

The authors calculated the correlation coeffi. of the scores of 3+X entrance exam and the scores of coursesat university in medical students of clinical medicine, medical imaging, anesthesiology. We found that there were rela-tionship among the overall score and English score of 3+X entrance exam as well as the scores of most major coursesat university in medical students, and there were relationship among the scores of chemistry and physics at entranceexam as well as the scores of partial major courses in the beginning at university. The result also indicated that entranceexam had a good prediction.[

Medicine is a practicing and experiencing subject.The most important study method for medical students is to practice during clinic.With the development of society,patients' consciousness of sticking up for their rights is stronger and stronger.During their receiving medical treatment,they are not satisfied with the teaching behavior provided by physician,and even to make medical conflicts.To resolve these conflicts,it is necessary to rule the clinical practicing teaching,harmonize the relationship between clinical teachers,medical practicing students,and patients.Medical education should be based on humanity and should be behaved by law.
