外旋外展推顶法治疗肩关节前脱位

目的：探讨外旋外展推顶法治疗肩关节前脱住可行性及疗效。方法：自1995年1月～2009年12月,采用外旋外展推顶法治疗肩关节前脱住500例,治疗后根据恢复症状及并发症,分析治疗方法的可行性及疗效。结果：所有患者均获得随访,时间为6个～1年;500例治愈432例。好转68例,无效O例。结论：外旋外展推项法治疗肩关节前脱住是一种可行的方法,较其他方法有更大的优点。     

异基因造血干细胞移植受者代谢综合征的发生情况

异基因造血干细胞移植（hematopoieticcelltransplantation,HCT）后代谢综合征的发生主要由预处理导致的神经激素系统紊乱、血管内皮损伤、移植物的免疫和炎症作用以及继发的移植物抗宿主病及其治疗等引起。对代谢综合征及其组分（糖尿病、高血压、血脂紊乱等）的筛查可以尽早地调整治疗策略,控制危险因素的发生,进而降低远期的心血管疾病的发生率和致死率。为此,美国的研究人员回顾性分析了86例异基因HCT受者代谢综合征的发生情况,并与代谢综合征在普通人群中的流行情况进行比较。     

A new variant of the ATP13A2 gene in Chinese patients with early-onset parkinsonism

Parkinson＇s disease （PD） is the second most common neurodegenerative disorder characterized by a selective loss of nigrostriatal dopaminergic neurons. Clinical manifestations of this complex disease include resting tremor, bradykinesia, postural instability, gait difficulty and rigidity. Approximately 5%-10% of patients have genetic factors, yet etiology of PD remains unclear. Genetic deficits, environmental exposure, oxidative stress, mitochondrial dysfunction,     

Safety and efficacy of a novel polyethylene glycol hydrogel sealant for watertight dural repair

OBJECT: The authors prospectively evaluated the safety and efficacy of a novel polyethylene glycol (PEG) hydrogel sealant in patients undergoing elective cranial surgery with documented cerebrospinal fluid (CSF) leakage after sutured dural repair. METHODS: The PEG hydrogel sealant was used at 11 different study sites in 111 patients with documented intraoperative CSF leakage after neurosurgical dural repair for a variety of conditions. Intraoperative CSF leakage was either spontaneous or induced by a Valsalva maneuver. Patients were monitored for 3 months postoperatively with physical examinations, clinical laboratory analyses, and diagnostic imaging. The PEG hydrogel sealant was 100% effective in stopping CSF leakage in all patients. There were no sealant-related adverse events and all clinical outcomes were consistent with expectations for seriously ill patients undergoing prolonged neurosurgical procedures. CONCLUSIONS: The PEG hydrogel sealant provides a safe and effective watertight closure when used as an adjunct to sutured dural repair during cranial surgery.     

HIV-1包膜蛋白2G12和2F5中和表位的改造对假病毒形成及中和活性的影响

目的 研究HIV-1膜蛋白(Env)特定中和表位的改造对功能性假病毒形成及中和活性的影响.方法 采用环形诱变及Dpn I筛选的方法对Env进行定点突变,将2G12和2F5两个中和表位整合入不含该表位的BC亚型的Env上,比较改造对假病毒的形成情况及对2G12和2F5单抗的中和活性的影响.结果 对5株假病毒(BC02、BE03、BC04、BC05和BC12)的Env特定中和表位进行改造,其中BC04和BCl2的2G12表位改造后,不能形成假病毒,BC02、BC03和BC05增加2G12和2F5两个表位后,仍能够形成假病毒,且假病毒滴度较改造前无明显变化,改造后的BC03假病毒较改造前对单抗2G12和2175的中和活性均有所提高,而改造后的BE02和BC05假病毒较改造前对单抗2F5的中和活性增强,而对单抗2G12的中和活性无变化.结论 2G12中和表位部分位点的改造影响假病毒的形成,中和表位的增加能够提高单抗2G12的中和活性,为免疫原的优化提供了新思路.

Inflammatory and dysplastic lesions involving the spine

Dysplastic lesions of the spinal column include a wide spectrum of disorders that can occur secondary to metabolic, degenerative, and inflammatory processes. The clinical presentations are highly variable, depending on the location of the lesion and the extent of the systemic disease process. Common signs and symptoms include pain, scoliosis, myelopathy, and weakness. Surgical decision making is based on patient status, comorbidities, and extent of disease.
