We have successfully attained the fulllength cDNA sequence of FRG4, bioinformatic analysis shows FRG4 gene has 99%homology with Homosapiens synapse associated protein 1 (SYAP1), consists of 9 exons and 8 introns and located in Xp22.2. None transmembrane domains but a BSD domain was discovered, and its encoding protein is probably a water-solubility protein.

结果表明cDNA文库基础上运用热启动PCR获得FRG4全长cDNA序列，生物信息学分析显示FRG4基因与人类的突触相关蛋白有99%同源性；定位在X染色体的短臂2区2带2亚带2次亚带；由9个外显子和8个内含子组成；无跨膜区段；有一结构域BSD；该基因编码蛋白可能为一水溶性蛋白。

Statistical data of VEGF grading scores showed that its expression was not significantly related to the size and location of glioma, sex, and age of patients, but closely related to the glioma gradings. The expression of TF was positively correlated with that of VEGF, suggesting that TF might participate in the anigogenesis of gliomas, and provide proper environment for the growth of gliomas through its coagulant effect.

根据VEGF分级计数统计学分析，显示VEGF表达与肿瘤的大小、部位及患者性别、发病年龄等临床因素无显著相关性，而与肿瘤的组织学分级密切相关。3、胶质细胞瘤中TF与VEGF的表达正相关，TF可能参与了肿瘤血管的生成过程，并通过其促凝血活性作用为胶质瘤的生长创造适宜的内环境。

Statistical data of TF grading scores showed that its expression was not significantly related to the size and location of glioma, sex, and age of patients, but closely related to the glioma gradings and microvessel quantity of the tumor.VEGF was found in gliomas of all gradings and its expression was significantly enhanced with the increase of glioma gradings.

TF分级计数统计结果显示其表达与肿瘤的大小、部位及患者性别、发病年龄等临床因素无显著相关性，但与肿瘤的分级及肿瘤微血管数量密切相关。2、VEGF在各级胶质细胞瘤组织中均有表达，随着肿瘤组织学分级的增加，VEGF的表达明显增强。

In order to investigate the possibility of porous hydroxyapatite ceramics in the repair of skull bone defect, twenty-four rabbits were used. The bone defect model was created by operation to obtain a defect in parietal bone in a size of 1 cm x 1 cm. Filled the defect with HAC and methyl-methacrylate-syrene copolymer to fill the defect as control. At 1st, 2nd and 3rd months after operation, behavior of the rabbits was observed and then these animals were sacrificed and specimens were examined under microscope.

为了探索多孔羟基磷灰石陶瓷作为人工材料修复颅骨缺损的可能性，选健康家兔24只，切除颅顶骨造成缺损，分别用多孔HAC植片及无孔甲基丙烯酸甲脂－苯乙烯共聚物植片修复家兔颅骨缺损，于术后第1，2及3个月处死动物，进行术后反应及组织学观察。

At present, magnetic resonance imaging is the most sensitive imaging modality in detecting focal or diffuse parenchymal infection. However, there is no report about the in-patient distribution and MRI features of cerebral infectious diseases in Anhui province.

已公认MRI是检测脑实质内局灶性和弥漫性感染病变最敏感的影像学手段，但新时期有无新特点，本地区尚未见到有关脑内感染性疾病分布情况及其MRI特点的报道。

Models of physical activity, functional fitness, and the number of fall, and the fall efficacy among elderly according to different living arrangement and health status perceptions were identified.

本研究发现人口学变项、自觉健康、跌倒资讯的有无等变项和身体活动、体适能的交互作用，可以解释20.3%跌倒次数与28.6%跌倒效能的变异量。

Failing to learn how to use a computer would sentence a student to a life of underachievement.

For personnel who had unprotected exposure or a known breach in personal protective equipment to clinical material or live virus from a confirmed case of swine influenza A (H1N1), antiviral chemoprophylaxis with zanamivir or oseltamivir for 7 days after exposure can be considered.

在确诊猪流感（ H1N1）病毒的临床材料或活病毒中无保护暴露或已知个人防护装备破损的人员，暴露后可以考虑服用抗病毒化学药物奥司他韦或扎那米韦7天。

this gets sick the clinical symptom not to have the characteristic value, the medical history has the reference value.the sphere focus of infection has the crecent moon in the phantom performance to draft, the air bronchial tube drafts, the corona drafts to this sickness has the prompt value, sends the tubercle to see the small empty shade to have the diagnosis value, if in the discovery meniscus cavity has along with the body posture change "in the hole the ball drafts", has the important diagnosis value to the lung aspergillomycosis.this gets sick the diagnosis needs the pathology and the bacteriology inspection.

本病临床症状无特征性，病史有参考价值。在影像表现上球形病灶有新月征、空气支气管征、晕征对本病有提示价值，多发小结节均见小空洞影有诊断价值，如发现半月形空洞内有随体位改变的&洞中球征&，对肺曲菌病有重要诊断价值。本病的确诊需病理和细菌学检查。
