Objective:To explore the relationship of lymphocyte function-associated antigen 3 (LFA-3, CD58) expression in glioma with clinical features and its role in clinical prognosis. Methods:Clinical data and mRNA microarray data of 514 patients with glioma were obtained from The Cancer Genome Atlas and were used to study the expression of LFA-3 (CD58). Cox regression was used to analyze the relationship between CD58 expression and survival of patients with glioma. Multivariate analysis of variance was used to further analyze the relationship of CD58 with age, sex, and pathological grade of glioma. Results:The results of the stratified χ2 test of CD58 expression and tumor grading were shown, considering tumor type, gender and age of diagnosis (all P<0.05). CD58 expression was sig-nificantly correlated with overall survival (OS) and disease-free survival (DFS) of patients with glioma. Patients with high CD58 expres-sion presented short OS and DFS (P<0.0001). Conclusion:CD58 possibly promotes tumorigenesis in gliomas and thus can serve as a potential tumor diagnostic marker and individual therapeutic target.

Objective To study somatic cell embryogenesis of Acanthopanax senticosus induced by different concentration of 2,4D and type of explants,which provides theoretic evidence in protection of A.senticosus resources and genetic engineering.Methods Using 3-week seedlings and zygotic embryos(cotyledon, hypocotyls,and roots) of stratificated seeds as explants researches the effect of different hormones on somatic cell embryogenesis of A.senticosus. Results Explants of zygotic embryos of stratificated seeds cultured on MS and 1/2MS media containing 0.5 mg/L 2,4-D generated the highest frequency(57.1%) and the most number(3.3) of somatic cell embryos,which can develop into maturation in the initial medium.But it is more beneficial to generate new somatic cell embryos and to develop primary somatic cell embryos into maturation when transferred into 2,4-D of decreased concentration.And the deve-(lopment) process of somatic cell embryos of A.senticosus is similar to that of zygotic embryos.Conclusion(Somatic) embryogenesis of A.senticosus is realized by culturing explants of zygotic embryos and the inductive rate of somatic cell embryos is related to the concentration of 2,4-D and developmental stage of explants.

BACKGROUNDCorrect diagnosis is very important to patients with suspected lung cancer. According to the higher ¹⁸F-FDG intake of tumor tissues much more than normal tissues, this study evaluates the clinical value of ¹⁸F-FDG dual-head coincidence SPECT/CT in diagnosis of lung cancer.

METHODSSixty-one patients with lung mass underwent ¹⁸F-FDG dual-head coincidence SPECT/CT imaging and thoracic CT imaging before operation. These imageological results were compared with histological examination of lung mass.

RESULTSThe sensitivity, specificity and accuracy of ¹⁸F-FDG-SPECT/CT in differentiating malignant and benign lesions were 82%, 87%, 84%, respectively. Compared with thoracic CT imaging, diagnostic rate of mediastinal lymphatic metastasis was significantly higher by ¹⁸F-FDG-SPECT/CT (52% vs 81%, P < 0.05) .

CONCLUSIONSCombined functional-anatomical image of ¹⁸F-FDG-SPECT/CT has potential to improve staging and localizing procedures of lung cancer. It is an excellent modality in diagnosis and differential diagnosis of lung cancer.
