脊髓纵裂的手术疗效观察

收治脊髓纵裂４６例，其中２９例作神经功能状态的临床评价及胫后神经皮层体感诱发电位检查。结果：非手术组随访后神经功能缺陷无改善（Ｐ＞０．０５）；２０例手术组神经功能的临床评分明显增加及胫后神经皮层体感诱发电位明显改善（Ｐ＜０．０５）。表明手术不仅可阻止神经功能缺陷的发展，而且可使其得到改善，是一有效的治疗手段。     

皮肤老化的几种常见细胞和富血小板血浆治疗进展

皮肤抗老化领域的细胞治疗技术自问世以来,经历多次更新和优化,目前临床上公认安全性和效果较好的细胞治疗制剂包括脂肪干细胞及其培养基提取物、成纤维细胞、皮肤间充质干细胞以及富血小板浓缩物、富血小板血浆制剂等.然而,针对这些制剂的作用机制及优缺点还缺乏系统的总结,本文将对此进行详细阐述.     

尘螨变应原皮肤点刺试验与血清特异性IgE的相关性研究

目的 探讨尘螨变应原皮肤点刺试验(skinprick test,SPT)结果与血清特异性IgE(specific IgE,S-IgE)检测值之间的相关性.方法 分析170例接受尘螨变应原SPT和相应的血清S-IgE检测的变应性鼻炎患者不同皮肤风团直径和不同皮肤反应指数(skin index,SI)对应的血清S-IgE的差异.结果尘螨变应原SPT不同皮肤风团直径和不同SI对应的血清S-IgE存在显著性差异,随着皮肤风团直径或SI的增加,血清S-IgE阳性率和级别也显著增加.结论尘螨变应原SPT结果和血清S-IgE结果存在相关性.     

心内膜垫缺损的MRI诊断及其与超声心动图对比研究

目的:评价MRI诊断心内膜垫缺损(ECD)的价值和限度.方法:11例ECD患者,术前均行超声心动图和MRI检查,将诊断结果与手术病理对照.结果:MRI诊断ECD有11例,其中部分型心内膜垫缺损(PECD)6例,完全型心内膜垫缺损(CECD)5例;超声心动图诊断ECD有9例,1例CECD误诊为法乐四联症,1例CECD误诊为右室双出口.结论:MRI能较好的显示ECD的解剖畸形和复杂的血流动力学改变,在判断心脏血管畸形方面优于超声心动图,两种方法在诊断ECD中应互为补充.     

A Three-Dimensional Equivalent Stiffness Model of Composite Laminates with Wrinkle Defects

The stiffness of composite laminates is easily affected by wrinkle defects. In this paper, a new effective analytical model was proposed to predict the three-dimensional equivalent elastic properties of multidirectional composite laminates with wrinkle defects. Firstly, a geometric model was established according to the microscopic characteristics of wrinkle defects. Then, based on the classical laminate theory and homogenization method, the constitutive equation and flexibility matrix of the wrinkle region were established. Finally, the equivalent stiffness parameters of unidirectional and multidirectional laminates were derived, and the effects of different wrinkle parameters and ply-stacking sequences on the stiffness of unidirectional and multidirectional laminates were studied by using the analytical model. The results show that the mechanical properties of the lamina and laminates are affected by the out-of-plane angle and in-plane angle of the wrinkle defects. The accuracy of the analytical model has been verified by the numerical model and other theoretical models, and it has the characteristics of few parameters and a high efficiency. The analytical model can be used to predict the stiffness of composite structures with wrinkle defects simply, effectively, and quantitatively. It can also be used as a tool to provide the mechanical response information of laminates with wrinkle defects.

不同部位创伤性皮瓣修复对指腹缺损患者痛觉和感觉情况的对比研究

目的 研究对比不同部位创伤性皮瓣修复对指腹缺损患者痛觉和感觉情况的影响.方法 我院从2012年7月至2013年7月收治的发生指腹缺损者共86例患者86指,随机分为观察组和对照组.对照组给予腹部皮瓣修复术,观察组实施邻指皮瓣修复术.对比两组患者断蒂时间及两点识别值,术后痛觉、感觉恢复情况及其对手术效果满意度情况.结果 观察组术后断蒂时间及两点识别值显著小于对照组,术后痛觉、感觉恢复情况显著优于对照组,患者对手术效果满意度显著高于对照组,差异均有统计学意义（均P＜ 0.05）.结论 应用临指皮瓣修复术治疗指腹缺损,手术效果更好,且患者伤指术后痛觉及感觉恢复更佳,值得临床推荐.     

HIV感染者皮肤表征及研究进展

皮肤损害往往是HIV感染者最早和最常见症状,通过对文献的分析总结HIV感染者皮肤疾病的发生特点和研究进展。发现近年来的研究偏重于HIV感染者皮肤疾病方面的流行病学,而且都得出较高的发病率。但在皮肤疾病与免疫系统之间的关系研究还不透彻。     

Sudden hemorrhage without skin invasion in a patient with Breast Cancer: A case report and literature review

We report a rare case of sudden hemorrhage caused by breast cancer. A 70-year-old Japanese woman noted fresh bleeding from her left breast. On physical examination, continuous hemorrhage accompanied by an open cavity was observed in the left breast. Mammography and ultrasonography revealed a well-circumscribed mass, with solid and cystic components, that was highly suggestive of intracystic breast carcinoma with direct skin invasion. Computed tomography and bone scintigraphy showed no distant metastasis. Aspiration biopsy of the lesion showed several clusters of adenocarcinoma cells. Modified radical mastectomy was performed with a presumptive diagnosis of stage III B left breast cancer. Invasive ductal carcinoma without skin invasion was diagnosed histologically. To the best of our knowledge, only 6 other cases of sudden hemorrhage caused by breast cancer without skin invasion have been reported in Japan. We review the literature and discuss the clinical characteristics of this unusual phenomenon.
