0.05). Conclusion: There appears no clinical relationship between HBV and CAD.

The expressional capacity is an important element to the education of medical professional personality. The author discusses the close relationship among linguistic art as well as linguistic quality, humanistic quality, psychological quality and civilized words. The education of medical professional personality has objective demand for linguistic art. Brilliant expressional capacity plays an important role in establishing the harmonious relationship between doctors and patients, as well as exhibiting the doctor's charming personality.

This paper studies the Doctor-Patient relationship(DPR),especially about the logical system of the relationship.Through the positivism analysis,we compare the traditional DPR with the present DPR.

Gastrointestinal stromal tumors are the most common mesenchymal neoplasms deriving from the gastrointestinal tract.The prediction of its biological behavior has become a new hot spot of the research.This article reviewed the studies on predicting the biological behavior of gas trointestinal stromal tumors.

Objective To investigate the application of numerical simulation technique in supraorbital and frontal osseous defect.Methods The data of the patients with complex supraorbital and frontal osseous defects were obtained by helix CT scan.Numerical model based on the data was built up by computer.And the true model was produced by Rapid Prototyping.Being stimulated before this operation.the model was directly used in the operation.Results All of these 12 patients(one of defect of brow,four fracture of brow and zygoma,seven of old fracture of brow and zygoma)in this study were satisfied and their brows were symmetry after operation.All of them were satisfied after 1 or 2 years,without implantation exposure and transfiguration except one with infection.Conclusion Based on numerical technique difficulties of repairing,complex supraorbital and frontal osseous defect could be resolved by such process as collecting the bone data,stimulating operation by true models,and producing implantation before the operation.The accuracy of these operations can be improved.

Sentinel lymph node biopsy has been proved to be the standard treatment for early breast cancer patients with negative axillary lymph node. The study related to the tracer has become one of the hottest topics in breast cancer research. At present, the biopsy is often performed using the tracer of isotope, blue dye or both of them. However, some deifciencies of the 2 tracers restrained their applications, which resulted that the rate of the procedure is limited to only about 60% of patients in developed countries and less than 5% of patients in China and other developing countries. In recent years, a variety of new tracers have emerged, such as indocyanine green, contrast-enhanced ultra-sound using microbubbles, superparamagnetic iron oxide nanoparticles. In this article, we introduced the characteristics of these 3 substances and reviewed the related research on the new tracers. In conclusion, the new tracers are still in the preliminary stage of research, and further research is needed for clinical application.

Surfactant protein C(SP-C)is found to be expressed only in the alveolar type Ⅱ cells(AECⅡ),surfactant protein C gene mutations are found to be associated with Children interstitial lung disease.This review discusses the mechanism,diagnosis and therapy of the interstitial lung disease induced by the surfactant protein C gene mutations.

Objective To evaluate the value of barium meal examination in diagnosing heterotopic pancreas in the stomach and duodenum.Methods Five cases with pathologically or stomach endoscopy proved heterotopic pancreas were analyzed retrospectively with emphasis on imaging findings.Results Heterotopic pancreas localized in the stomach in 3(the antrum of stomach in 2 and the body of stomach in 1) and in the duodenal bulb in 2.On barium meal examination,the atypical findings were well-defined as oval or round masses with smooth margins and omphaloid barium patch in three,dilatation of heterotopic pancreatic duct in two.The lesions ranged from 1.5 cm to 3.5 cm in size.Conclusion The characteristic findings of heterotopic pancre as are well-defined as oval or round masses with smooth margins and omphaloid barium patch,and dilatation of heterotopic pancreatic duct.To understanding these X-ray findings may be helpful in making a correct diagnosis.

Purpose:To investigate the DNA content and cell proliferation during the course of development of golden hamster buccal pouch carcinoma.Methods:60 golden hamsters were divided into 6 groups,0.5% DMBA were application to the buccal pouch mucosas of 1～5 groups, and then animals were killed at 6W, 8W, 10W, 12W and 16W after application of DMBA, the animals of normal group were killed at 16W . Buccal pouch samples were taken and each sample was cut into two parts, one was processed histologically way, the other sample was detected and analysed with flow cytometry for DNA content and cell cycle.Results:Our results revealed that the DNA of normal mucosa and hyperplasia appeared diploid; there were 16.7% (2/12) of anuploid in the mild and moderate dysplasia; 33.3% (3/9) of DNA anuploid in severe dysplasia; 54.1(6/11)% of DNA anuploid in carcinoma in situ ; and 78.57% (11/14) of DNA anuploid in invasive carcinoma. DI value and S phase proliferation became higher as the mucosal lesion became heavier , the S phase of severe dysplasia was the highest (39.31%).Conclusions:DNA anuploid is the marker of malignant tumor; the cell rate of S phase can be considered a sign of malignant tumor proliferation , it is a valuable guide for clinical treatment and prognosis assessment in oral carcinoma .

[Objective]To study the pertinency of position of the lesser trochanter and lateral shaft of femur for internal fixation of fracture of the lesser trochanter.[Method]One hundred and twenty thigh bones were taken X-ray films on normotopia and lateral position,anatomical observation and measurement of the the lesser trochanter were completed with angel and length relative to lateral shaft of femur.[Result]Vertical axis length of the lesser trochanter was 26.38?2.44 mm and transverse diameter was 15.61?1.49mm.Its retroverted angle was 17.66??10.56?and uptilted angle was 26.33??3.33?.[Conclusion]The appropriate position in fixation of the fracture of the lesser trochanter is the point on the besctor of the lateral cortex of the femur on level of the lower of the lesser trochanter.Its retroverted angle is 10?-15?and uptilted angle is 25?-30?.The length of the screw is 45-50 mm,it is beneficial to design the plate in femur with the data.
