Extragastrointestinal stromal tumor possibly originating from the prostate

We report a case of extragastrointestinal stromal tumor possibly originating from the prostate. The patient underwent radical prostatectomy because of no metastatic evidence. No recurrence and metastasis have been found during 14 months of follow up. To our knowledge, this may be the third such case published in a report in terms of pathological type.

Nerve growth factor and tyrosine kinase A in human salivary adenoid cystic carcinoma: expression patterns and effects on in vitro invasive behavior.

PURPOSE: Perineural invasion is a frequent occurrence in salivary adenoid cystic carcinoma (ACC) and may prevent complete surgical resection. Studies have indicated that nerve growth factor (NGF) and its high-affinity receptor tyrosine kinase A (TrkA) may play a role in perineural invasion in several malignancies in which perineural invasion is observed. The present study was conducted to investigate the expression of NGF and TrkA in salivary ACC and to examine the effects of NGF on adhesion, migration and invasion capacities of a salivary ACC cell line (SACC-83) in vitro. PATIENTS AND METHODS: Expression of NGF and TrkA was explored using immunohistochemistry in paraffin-embedded tissues of 32 cases of salivary ACC. The effects of NGF on in vitro adhesion, migration, and invasion capacities of the SACC-83 cell line were examined using an MTT assay and a modified Boyden chamber assay respectively. RESULTS: In ACC specimens, 31 (96.9%) and 32 (100%) tumors showed immunoreactivity for NGF and TrkA respectively. Significant correlations were found between NGF/TrkA expression levels and perineural invasion (P < .05). In cell adhesion assay, the percent adherences of SACC-83 cells co-cultured with 25 ng/ml NGF at 1.5 hours and 5, 25 ng/ml NGF at 6 hours were significantly higher than that co-cultured with 0 ng/ml NGF (P < .05). However, high concentration of NGF (500 ng/ml) resulted in a significant inhibition of invasion (P < .05). CONCLUSION: Overexpression of NGF and TrkA in human salivary ACC tissues may constitute a reason for perineural invasion in salivary ACC.     

γ射线照射对血小板活化的影响

目的:探讨γ射线照射对单采血小板保存过程中血小板活化的影响.方法:用细胞分离机单采血小板20人份,以27Gyy射线照射,标准条件下保存5天,间隔取样分别用RIA,ELISA方法检测血小板表面P-选择素(P-Selectin)、血浆中可溶性P-选择素(sP-Selectin)及β-血小板球蛋白(β-TG)含量.结果:在保存3d,5d后,照射组及对照组中血小板表面P-Selectin含量、血浆中sP-Selectin及β-TG含量与保存前比较差异显著(P＜0.05),但是两组间比较无统计学差异(P＞0.05),结论:γ射线照射不会促进血小板的活化.     

用视诱发电位和富里叶变换作视力客观估计

目的:研究用图形视觉诱发电位(PVEP)和离散富里叶变换(DFT)作视力客观估计的方法。方法:检测对象为33只正常眼。用翻转频率为10次/秒,条纹张角分别为30、20、18、12、10、6、4和2弧分的垂直方波光栅图形刺激,记录相应的稳态图形视诱发电位。用离散富里叶交换提取WEP频谱中10Hz成分的幅值。以光栅条纹张角为横坐标、相应的VEP频谱幅值为纵坐标作关系曲线,取阈值附近的近似线性部分的数据点作直线回归,用外推法求得阈值和视力。结果:比较VEP所测之视力与用国际标准视力表所测之视力,可见在本研究中70％的受检眼VEP视力估计较准确。结论:用本研究中的VEP技术客观地测量视力可靠性较高。眼科学报1997;13:59～61。

补碘对7～12岁轻度碘缺乏病儿童脑功能及生长、发育的影响

通过半年对３５名７～１２岁轻度碘缺乏病儿童进行补碘，并与同龄、同地的正常儿童和缺碘未补碘儿童进行比较，以观察补碘对儿童脑功能及生长发育的影响。结果发现：①补碘可使儿童碘营养状况恢复正常，尿碘值由（８３．２±３．５）μｇ／Ｌ上升到（１６２．２±１．６）μｇ／Ｌ，血清Ｔ４、ＦＴ４Ｉ和ｒＴ３：也与正常儿童一致而与未补碘儿童有显著性差异（Ｐ＜０．０５）．②轻度碘缺乏病儿童智商低于正常儿童（Ｐ＜０．０１），补碘在一定程度上改善其智商水平。③轻度碘缺乏病及补碘未能明显影响儿童的生长发育，可能与儿童总营养水平较差有关。
