肱骨外科颈骨折微创治疗新进展

切开复位钢板内固定方法由于对骨折局部软组织损伤较大,骨折周围的血供遭到了破坏,不利于骨折愈合。国内最成功的治疗方法是手法整复,超肩关节小夹板外固定。这些整复和固定方法都是中医骨伤科珍贵的医学资源,是几千年来的经验和技术的积累,我们更应发扬光大。     

野外骨折的急救

经常跋山涉水、遍访旅游胜地的朋友,稍不留神就会崴了脚、脱了臼,甚至伤筋动骨,所以本文要介绍一下在野外遇到上述情况后应采取的急救措施。骨折的通用急救惯例 所谓骨折,是指由于外伤或骨组织本身的病变,而使骨头折断、变成碎块或发生裂纹的现象。骨折可以发生在人体的各个部位,共分为     

Science Letters： A synthetic Toll-like receptor 2 ligand decreases allergic immune responses in a mouse rhinitis model sensitized to mite allergen

It has been proposed that activation of Toll-like receptors （TLRs） plays crucial roles in the polarization of adaptive immune responses. A synthetic Toll-like receptor 2 （TLR2） ligand, Pam3CSK4, has been reported to modulate the balance of Th1/Th2 responses. We evaluated the modulation effect of Pam3CSK4 on allergic immune response in a mouse rhinitis model sensitized to house dust mite allergen （HDM）. Mice were sensitized and challenged with Dermatophagoidesfarinae allergen （Der f）, and then the allergic mice were treated by Pam3CSK4. Nasal allergic symptoms and eosinophils were scored. Der f-specific cytokine responses were examined in the splenocytes and bronchoalveolar lavage fluid （BALF）. Serum level of total IgE was also detected. After establishing a mouse allergic rhinitis model with HDM, we have showed that Pam3CSK4 treatment not only ameliorated the nasal allergic symptoms remarkably but also decreased the eosinophils and total inflammation cells in BALF significantly. Analysis of cytokine profile found that IFN-7 released from either BALF or stimulated splenocytes increased markedly in Pam3CSK4-treated mice, while IL-13 decreased significantly. Moreover, serum level of total IgE was significantly lower in Pam3CSK4-treated mice than in the untreated. Thus, in an allergic rhinitis mouse model developed with HDM, Pam3CSK4 was shown to exhibit an antiallergic effect, indicating its potential application in allergic diseases.

家兔髋关节软骨扫描电镜观察

应用扫描电镜对家兔髋关节软骨观察发现:月状面软骨表面和股骨头软骨表面均具由纤维编织而成的网状层,月状面软骨顶部,纤维交错,网状层形态结构复杂而又丰厚;前部与后部次之,股骨头顶部,关节软骨表面的网状层显著低矮、致密,并有一矩形凹陷;下部,网状层呈斑块状,高低错落。     

半环式传感型骨外固定器的力学特性实验

通过对尸胫骨 -传感器骨外固定器系统的动、静刚度及应力遮挡率进行了实验研究 ,表明半环四针传感型骨外固定器较两针型的刚度大 ,因此在骨愈合初期、粉碎性骨折宜采用四针结构 ,以避免错位、成角 ;愈合中后期用两针结构 ,以减小应力遮挡     

测量嗅觉诊断病症的"临床鼻"

如今，一项称为“临床鼻”的医疗产品在新加坡问世，该产品能让医生通过测量人的嗅觉，来诊断出病人是否患上相关疾病，甚至是帕金森症及早老性痴呆症。     

软骨组织工程新进展

软骨组织工程技术为治疗骨、软骨疾病提供了一种新的方法，其主要技术路线是，通过种子细胞和生物活性支架的体外共培养实现软骨组织的再生，并最终完成组织的修复与重建。种子细胞的选择、支架的构建，培养条件的优化对软骨再生有重要作用，从而成为目前软骨工程领域的研究重点。
