Expansive type of hepatocellular carcinoma (HCC) is a subtype of HCC. Correlation between the preoperative sonography and postoperative pathology was studied in 35 cases of HCC. According to the classification of nakashima, 21 cases belonged to the expansive type whereas the other 14 cases the infiltrative type. Different from the infiltrative type. the expansive type of HCC had four specific sonographic appearances: hypoechoic ring, hypoechcic halo, pedunculated and small nodular echo which had different pathological bases. Expansive tyje of HCC was not so commonly seen as infiltative type but its rate of surgical resection was mu~h higher than that of infiltratine type (JP< 0. 01). Thus, it is the kind of HCC with significant clinical importance. Preoperative ultrasonographic diagnosis help to decide the way of treatment.

HLA (human leukocyte antigen) is critical molecule relevant to immunoresponse, which is always involved in antigen presentation and determining killing activity of immune cells against tumor. The abnormal expression of HLA in lung cancer is believed to be a common phenomena of tumor biology. It has been demonstrated that HLA expression varies in various types of lung cancer, even in differential stages of one type of lung cancer. HLA expression is highly associated with genre, progression and prognosis of lung cancer. The thorough investigations of the relationship between HLA and lung cancer and of mechanism of HLA abnormality will provide useful information for studying of development of lung cancer and tumor immunotherapy.

At present clinic study and use of anti-tumour platinum drug are wide and active. The paper reviews progression of clinic study and use of anti-tumour platinum drug and expects its prospect.

Objective To study the inhibitory effect of yan xiao capsules on hepatocarcinoma mice. Methods Forty mice were randomly divided into control group ,CTX group,ADM group,trial group. Observe tumour weight ,the span time of tumour-bearing mice, tumour morphology and the mortality rate of ascites cancer cell by direct killing respectively. Results The tumour weight markedly decreased in trial group, the rate of inhibition tumour was 52.0 %(P

Spine metastasis stereotactic body radiation therapy delivers conformal high radiation dose to the tumor target, and steep falloff dose gradients protect adjacent normal structures, especially spinal cord. Some studies demonstrated stereotactic body radiation therapy for metastatic tumors of the spine is safe and clinically effective. This technique markedly improved local control with an excellent symptomatic response compared with conventional external beam radiation therapy techniques, and is beginning to change the treatment paradigms for metastatic spine disease both as post-operative adjuvant therapy and primary definitive local treatment. Although the technique is being increasingly used in clinical practice, the optimal fractionation schedule remains uncertain. Based on the research of radiobiologic principles, radiological physics and clinical data, multiple session stereotactic body radiation therapy has some advantage in clinic.

Objective To investigate the relationship of self-management skills and the quality of life among solitary elderly patients with hypertension.Methods 110 cases of solitary elderly patients with hypertension were measured with self-designed Self-management of Hypertension Scale and Short Form Health Survey (SF-36) and the correlation of them was analyzed.Results The levels of self-management skills of elderly hypertensive patients was at a middle level,and the mean score of self-management skills was (78.6 ± 5.2) points.The total score of SF-36 of patients with good self-management skills was higher than those with bad self-management skills.The therapy management,catering management,psychosocial management,sports management and overall quality of self-management of elderly patients with hypertension were positively correlated with survival quality.The factors influencing self-management ability of patients incuded education,gender,social resource utilization,psychological conditions.Conclusions Community health nurses should pay attention to self-management skills such as diet,exercise,therapy,social and psychological aspects in elderly hypertensive patients in order to improve their quality of life.Furthermore community nurses should strengthen intervention for solitary eldedy males with lower education level,poor utilization of social resources to improve their self-management skills.
