儿童颈椎间盘钙化症的影像诊断

目的 探讨儿童颈椎间盘钙化症的影像表现及诊断价值，并提高对本病的认识。方法 回顾分析16例儿童颈椎钙化性椎间盘病的影像表现。结果 16例患均行颈椎平片检查，5例行CT扫描并作了三维重建，8例行MRI检查。16例平片均显示了椎间盘钙化灶，均为单发，CT平扫加三维重建显示4例钙化呈卵圆形，1例钙化为不规则形。MRI检查不仅显示了椎间盘内改变还清晰显示了病变相邻椎体边缘信号改变，在T1、T2加权像上呈低信号。结论 平片检查可以显示椎间盘钙化；CT平扫加三维重建能清晰显示了钙化灶的大小、形态；MRI检查在显示受累椎体及周围组织的改变方面明显优于CT和平片。

量化健康教育在CCU住院病人健康教育中的应用

医院健康教育是护理人员通过各种教育形式使病人或家属获得预防疾病、促进康复、保持健康知识的护理活动[1]。它有多种教育形式,本文就量化健康教育与随机健康教育效果进行比较。1对象与方法1.1对象2002年1月—2004年1月,知道自己所患病情,能清楚表达自己意愿的200例CCU住院病人为对象。按随机数字表将200例病人分为实验组和对照组。实验组男68例,女40例,年龄(58.7±6.9)岁;初中及以下35例,高中及以上73例;高血压36例,急性心肌梗死13例,不稳定性心绞痛17例,恶性心律失常27例(行起搏器植入术7例),急性左心衰竭15例。对照组男60例,女32例,年…     

Turner氏综合征的临床与骨改变分析(附15例报告)

目的通过对15例有详细的临床及影像资料的Turner氏综合征分析,探讨先天性卵巢发育不良综合征(Turner)的临床与骨改变特点。方法收集15例Turner氏综合征临床及骨骼X线平片,分析其表现。结果染色体核型分3型,第1型45,X,8例;第2型46,XX,5例;第3型46,XX/45,X,2例。X线表现有:骨质稀疏14例,掌骨征阳性8例,指骨优势9例,肘外翻10例,脊柱骨化不良5例,足趾趾节短9例,颅底凹陷11例。结论Turner氏综合征患者最终身高明显低于正常人群,智力低下,性发育不全。X线表现典型,骨改变对临床的诊断具有主要参考价值。     

Lipid extract from completely sporoderm‐broken germinating Ganoderma sinensis spores elicits potent antitumor immune responses in human macrophages

Ganoderma sinensis has been used widely in Oriental countries for the prevention and treatment of various diseases including cancer. Previous studies have shown that the lipid extract from Ganoderma exhibits direct cytotoxicity against tumor cells. Here, it is reported that the lipid extract from germinating G. sinensis spores, at lower concentrations that have no direct tumoricidal activity, induce potent antitumor immune responses in human monocytes/macrophages. Upon stimulation with the lipid extract, monocytes/macrophages exhibited markedly increased production of proinflammatory cytokines and surface expression of costimulatory molecules. Conditioned medium from stimulated cells effectively suppressed the growth of tumor cells. Apparently, the lipid extract triggered macrophage activation via a mechanism different from that associated with LPS. Moreover, it was observed that the lipid extract could partially re‐establish the antitumor activity of the immunosuppressive tumor‐associated macrophages. These results indicated that in addition to its direct tumoricidal activity, the lipid extract from G. sinensis spores could exert antitumor activity by stimulating the activation of human monocytes/macrophages.

Kindergarten children's representation and understanding of written number symbols

Two samples of kindergarten children's representation and understanding of written number symbols were examined in two time points in one academic year. About 85% of Chinese five year olds (mean = 5 years 10 months) were able to use conventional number symbols to represent the quantity of 30 or larger. At the end of the kindergarten year, 94% of Chinese six year olds (mean = 6 years 4 months) were able to use conventional number symbols to represent the quantity of 100 or larger. Some Chinese six year olds had problems in representing written addition and subtraction tasks. Children's ability to represent written number symbols, ability to represent written addition and subtraction formula and their performance on written addition and subtraction were closely related. The performance of children in a university-affiliated childcare center was better than that of the center serving working-class families in Time 1, but the performance reversed at the end of the kindergarten year.     

肩胛骨骨折的螺旋CT多平面和三维重建诊断

目的 探讨螺旋CT多平面重建（MPR）、表面遮盖显示法（SSD）及最大密度投影法（MIP）在肩胛骨骨折诊断中的价值。方法 回顾性分析40例肩胛骨骨折患者的MPR、SSD及MIP图像；所有病例均用Mareoni Ultra Z型螺旋CT机扫描，并在图像工作站上用MPR、SSD及MIP技术获得多平面和三维图像。结果 MPR、SSD及MIP重建图像清晰显示了40例共45处肩胛骨骨折及7例肩关节脱位；MPR、SSD及MIP能多方位、立体、全面地显示肩胛骨骨折部位和程度。MPR在显示微小骨折方面较好，而MIP、SSD在显示骨折的位置、形态、范围及移位方面较好。结论 MPR、SSD及MIP是诊断肩胛骨骨折的有效方法，对肩胛骨骨折分类、手术入路及内固定器选择等方案的制定有帮助。
