Objective Detected Her-2/neu, matrix metalloproteinases-2 (MMP-2) and Leptin in stomach cancer serum and tissue, discussed their roles in occurance and development of gastric cancer. Methods Detected the ex-pression of Her-2/neu, MMP-2 and Leptin in serum by ELISA, and detected the expression of Her-2/neu, MMP-2 and Leptin in stomach cancer tissue by IHC. Results The positive rates of Her-2/neu, MMP-2, Leptin in gas-tric cancer serum were higher than the positive rates in control group ( P<0.05 ) . The positive rates of Her-2/neu, MMP-2, Leptin in gastric cancer tissues were higher than the positive rates in adjacent tissues (P<0.05 ). The positive expressions of two tests had consistency. In tissues, the positive expression rates of Her-2/neu,MMP-2 and Leptin were correlated with the depth of invasion,lymph node metastasis, clinical stage(P<0.05). Their ex-pression was not correlated with sex, age, size, site of tumor and the degree of differentiation. In serum, the posi-tive expression of Her-2/neu was correlated with the depth of invasion, lymph node metastasis, clinical stage( P<0.05 ) . The positive expression of MMP-2 was correlated with lymph node metastasis ( P<0.05 ) . The positive ex-pression of Leptin had no significant correlation with pathological features. Conclusion Her-2/neu,MMP-2 and Leptin promote the occurrence, development and transfer process of gastric cancer. It can be used for clinical diag-nosis, guide the targeted therapy and provide scientific and reasonable reference for gastric cancer prognosis.

Objective To study the therapeutic effect of TK/GCV in the treatment of acute graft-versus-host disease in H-2 haploidentical mice induced by CD34 + cells mixed with TK + T lymphocytes transplantation.Methods CD34 + cells were separated from male parental donors,bone marrows,meanwhile T lymphocytes were gained from their spleens and transduced by retroviral vectors comprising TK gene. Both were mixed and transfused into female F1 recipient mice,CD34 + cells and TK + T lymphocytes each F1 recipient mouse received were 1?10 5 and 1?10 7,respectively. GCV was administered at the dosage of 50 mg ?kg -1 ?day -1 for 7 by intraperitoneal injections on the day 0 or 7 after transplantation.Results Acute GVHDs appeared in all mice. Survival time of the mice treated with GCV on the day 0 or 7 after transplantation was ( 26.6 ? 4.8 ) days and ( 40.5 ? 8.4 ) days,respectively. Therapeutic effect of GCV on the day 7 posttransplantation was better than that on the day 0 posttransplantation ( P

Objective: To investigate the quality control for purpose of radiologic protection in beside Photography. Methods: From a clinical application, based on the thress principle of radiological protection, combined with years of clinical experience, the need for comprehensive study bedside photography and protection security. Depending on the situation ,put forward corresponding countermeasures. Results: The different patient, especially in children photography and treatment of critically ill patients, with a reasonable operation mode, the method can reduce the radiation. Conclusion:The widespread popularity of medical radiological protection education, strengthen the quality control of bedside photography on bedside X-ray photography protection is very useful.

Diffuse large B-cell lymphoma (DLBCL) represents the most common type of malignant lymphoma. DLBCL is heterogeneous with respect to morphology, immunophenotype, biology, clinical presentation and outcome. Constitutive activity of the NF-κB pathway may contribute to the poor prognosis of patients with activated B cell-like (ABC) subgroup of DLBCL, caspase recruitment domain 11 (CARD11) is the important signal protein in the signaling pathway of NF-κB. Furthermore, various pre-clinical data have proved the importance of CARD11 in DLBCL. This review summarizes the biological characteristics of CARD11, and its relationship with NF-κB signaling transduction pathway and the outcome of DLBCL, so that we can better understanding the pathogenesis and new therapeutic target of DLBCL.

BACKGROUND: Spiral CT three-dimensional reconstruction has been used to observe the femoral head coverage fate of developmental dislocation of the hip (DDH). However, most of research containing certain observing point, which lack of long-term follow-up and comprehensive analysis. This article wants to fill the gaps.OBJECTIVE: To study changes of femoral head coverage fate in DDH child after 3 years treatment by CT reconstruction. METHODS: Totally 73 patients with unilateral DDH treated by aluminium plate after manual close reduction was selected. Spiral CT scanning of femoral articulation was performed at 1 day before and 12, 24, and 36 months after reduction to measure the femoral head coverage fate changes. The normal hip of patient was served as control.RESULTS AND CONCLUSION: All patients were included in the 42-53 months follow-up. After treatment, the femoral head coverage fate of patients were obviously than that of before treatment (P<0.01), which gradually approach to the normal level in 3 years, the first year after treatment is a key period for acetabulum development.

Medical examination is an important measurement of evaluating the teaching effect and studying results,and also is the main method and content of teaching quality evaluation in universities and colleges.During the teaching evaluation we found that many problems of medical examination need to be solved and improved.This paper deals with three major aspects closely related to teachers including the standardization of programming test paper,rating the test scores,and statistical analysis of the examination papers.
