This paper describes an algorithm of extracting location information in 2D eyeball ultrasound slices. The relative position of eyeball slices is adjusted based on the correlation between the slices. Some middle slices are added with elastic matching-based interpolation algorithm. Then ray-casting algorithm for volume rendering is used to reconstruct 3D image of the eyeball.

It was found that protooncogene c-fos was over-expressing in SAC-IIB_2 cell strains. Targeting the code 2-7 sequence of c-fos cDNA of mice, we designed and synthesised eighteen mers antisense. sense and nonsense oligodeoxynucleotides(ODN). The results indicated that antisense c-fos ODN could induce SAC- IIB_2 maturative differentiation, inhibit its growth rate, decrease its ability of forming tumor in nude mice and expression of Fos protein, however, antisense ODN has no remarkable effect on cellular dynamics of SAC-IIB2. But sense and nonsense c-fos ODN have no similar effect on SAC-IIB_2 cell strains. The results demonstrated that antisense c-fos oligodeoxynucleotide has inhibition effects on malignant phenotype of mice SRS lymphoma cell.

Alanine aminotransferase (ALT)abnormality is an indicator of the degree of liver inflammation caused by immune activation in patients with chronic hepatitis B (CHB).However,approximately half of the CHB patients with normal or mildly elevated ALT levels have concealed significant changes in hepatic histology.CHB patients with normal or mildly elevated ALT levels may have significant histopatho-logical changes in hepatic tissues,and those changes vary between HBeAg(+)and HBeAg(-)CHB patients.Attention and investigation on the clinical management of CHB patients with normal or mildly elevated ALT levels may have great significance in grasping the right treat-ment opportunity and reducing the risk of liver cirrhosis.

AIM: To investigate relationship between activity of matrix metalloproteinases-2 ( MMP-2, 72 kD) and invasion, metastasis of breast cancer. METHODS: Useing zymography and computer software assisted analysis, the activitive levels of MMP-2 (72 kD) in tissues from breast cancer were measeured. RESULTS: Mean activitive levels of MMP-2 72 kD (13.93?3.60) in breast cancer were lower than those in benign disease (21.43?8.31), P0.05) in MMP-2 62 kD+72 kD of benign and malignant disease, but MMP-2 62 kD (13.83?4.53) and MMP-2 62 kD/62 kD+72 kD(0.48) respectively were significantly higher in malignant disease (P

AIM: To study the role of c-myc oncogene in L6565 leukemia oncogenesis and the effects of therapy by inhibition of its expression with antisense c-myc. METHODS: A recombinant retroviral vector containing antisense c-myc of the murine (pGNCas)was constructed and then transfected into PA317 cells by the method of calcium phosphate precipitation. L6565 clone cells were infected with retrovirus particles. Stable integretion of antisense c-myc was shown by PCR. The change of the malignance and phenotype of L6565as were detected by the examination of the growth, morphology, cells cycle, agar assay and expression of c-myc. RESULTS: The shape of most L6565as cells became spherical. The growth of L6565as was inhibited compared to control cells. The analysis of cells cycle: L6565as cells were arrest in G 0/G 1 phase, decreased in S phase. The ability of L6565as cells to form colony in soft agarose was significantly suppressed. c-myc in L6565as cells was lowly expressed. CONCLUSION: (1)c-myc plays a critical role in L6565 leukemia oncogenesis; (2)Inhibition of expression of c-myc makes partly reversion of malignant phenotype of L6565 murine leukemia clone cells.

In order to promote our country's research on transitional care for patients with chronic kidney disease (CKD),the article summarized research progress on transitional care for patients with CKD,analysed the problems existed including lack of evidence-based basis,insugiciency of Intervention staff,one-sided intervention content and effect evaluation,etc,and put forward the corresponding countermeasures.

Objective To observe the effects of different dosages of granulocyte-macrophage colony-stimulating factor (GM-CSF) on generating the routine bone marrow dendritic cells, and supply suitable dosage of GM-CSF on preparation of dendritic cell vaccines used for different purpose. Methods Using low (5 ng/ml) and conventional (20 ng/ml) and high dosage( 50 ng/ml ) of GM-CSF combined interleukin-4 ( IL-4 ) to induce murine bone marrow dendritic cells were performed, The phenotypes (CD_(11c), CD_(80), CD_(86)) and functional properties of the DC were compared by FACS analysis and MLR. Results The DC induced by low dosage of GM-CSF were immature DC, expressing low CD_(11c), CD_(80), and CD_(86). DC induced by conventional dosage were functional mature, expressing higher CD_(11c), CD_(80), CD_(86), which could induce allogeneic T lymphocyte responses. DC induced by the high dosage GM-CSF were the most phetotypicaUy and functional mature cells, expressing the highest CD_(11c), CD_(80) CD_(86), which could induce the strongest allogeneic T lymphocyte responses. Conclusion The dosages of GM-CSF affect the maturation stage of dendritic cells. Low dosage of GM-CSF generated immature dendritic cells, but conventional dosage and high dosage generated mature dendritic cells. DC generated through high dosage of GM-CSF were the most mature in phenotype and function.

Paraneoplastic neurological disorder (PND) is a condition due to immune cross-reactivity between the tumour cells and the normal tissue, whereby the “onconeural” antibodies attack the normal host nervous system. It can present within weeks to months before or after the diagnosis of malignancies. Nasopharyngeal carcinoma is associated with paraneoplastic syndrome, for example, dermatomyositis, and rarely with a neurological disorder. We report on a case of nasopharyngeal carcinoma with probable PND. Otolaryngologists, oncologists and neurologists need to be aware of this condition in order to make an accurate diagnosis and to provide prompt treatment.

This study was aimed to evaluate the efficacy and safety of Y ixin Tongmai Decoction in prevention and treatment of diabetes mellitus complicated with coronary heart disease ( CHD ) after coronary stenting restenosis . Sixty cases were randomly divided into the conventional western medicine treatment plus Y ixin Tongmai Decoction group ( treatment group ) and conventional treatment of western medicine group ( control group ) . Observation was given on the in-stent restenosis before treatment and one-year after treatment . And the traditional Chinese medicine ( TCM ) Syndrome Scale , changes of single symptom in TCM syndrome , effect of Y ixin Tongmai Decoction on blood glucose and other adverse reactions were also observed before and one-year after treatment . The results showed that in the curative effect evaluation , the restenosis rate of treatment group was 6 . 90%, and the restenosis rate of control group was 17 . 24%. There was significant difference be-tween two groups ( P < 0 . 05 ) . According to the standard of TCM syndrome curative effect , the total effective-ness in the treatment group was 86 . 21%, and that of the control group was 31 . 03%. And there was signifi-cant difference between two groups ( P < 0 . 05 ) . In the safety evaluation , there were no obvious abnormalities during safety detection in the clinical study of two groups. There was no influence on blood sugar levels. And no drug related adverse reactions occurred . It was concluded that Y ixin Tongmai Decoction can reduce coro-nary stent restenosis rate in diabetes complicated with CHD (chest pain) with the syndrome of qi deficiency and blood stasis , phlegm-turbid stasis . It can significantly improve the TCM syndrome and single symptom of patients with good safety .
