HPLC法测定滑膜炎颗粒中原儿茶醛的含量

目的建立滑膜炎颗粒剂中原儿茶醛的含量测定方法质量。方法采用高效液相色谱法对方中原儿茶醛进行含量测定。结果高效液相色谱法测定结果表明原儿茶醛在0．1005～1．005μg范围内呈线性关系，平均加样回收率为99．22％；RSD为0．72％。结论本法简便，重现性好、结果可靠，可作为控制滑膜炎颗粒剂的质量方法。     

Extragastrointestinal stromal tumor possibly originating from the prostate

We report a case of extragastrointestinal stromal tumor possibly originating from the prostate. The patient underwent radical prostatectomy because of no metastatic evidence. No recurrence and metastasis have been found during 14 months of follow up. To our knowledge, this may be the third such case published in a report in terms of pathological type.     

人工髋关节置换术后脂肪栓塞综合征的观察与护理

笔者报道人工髋关节置换术后脂肪栓塞综合征的护理措施认为重视氧饱和度及动脉血氧分压监测，注意观察中枢神经系统症状和呼吸系统症状，及时发现并纠止低氧血症，对不同的病人制定不同护理方案，严密观察病情，及时掌握病情变化：是护理的关键。     

Use of the Arndt wire-guided endobronchial blocker via nasal for one-lung ventilation in patient with anticipated restricted mouth opening for esophagectomy.

Functional separation of the lungs may be accomplished by several methods. Patient with restricted mouth opening has limited options for one-lung ventilation. We report the use of wire-guided endobronchial blockade, a new tool for achieving one-lung ventilation in a patient with restricted mouth opening requiring nasotracheal, fiberoptic intubation for esophagectomy and reconstruction with gastric tube substitution.     

颈静脉球瘤的MR诊断

目的探讨MR检查在颈静脉球瘤诊断中的应用价值。方法对15例病变进行回顾性分析,重点分析其部位、信号及其侵袭性表现等情况。结果15例患者中,右侧病变8个(8/15),左侧7个(7/15);肿瘤形态为类圆形或不规则形,12例较大病变不同程度侵犯颈静脉孔区、乳突、岩骨、岩尖、斜坡等处骨质;肿瘤信号欠均匀,12个(12/15)肿块在MR平扫出现“盐和胡椒征”,以“胡椒”表现最为显著;13个肿块(13/13)均有明显强化,其中10个肿块出现“盐和胡椒征”。9例行MRA检查,颈内动脉和颈内静脉不同程度移位和包绕。结论根据肿瘤的部位、“盐和胡椒征”等MR表现,可在手术前正确诊断颈静脉球瘤。     

对代谢综合征病人疾病的认知程度及治疗依从性的调查

代谢综合征(metabolic syndrome,MS)是包括多种代谢紊乱的一组病理综合征。这些代谢紊乱之间具有密切而复杂的相互关系,是造成包括高血压病、糖尿病、心脑血管疾病在内的一组疾病的基础。MS患病率在世界范围内正以极快的速度增长,预防和治疗MS相关疾病的发生和发展,是目前备受关注的重大社会卫生问题[1]。笔者对119例MS病人进行MS认知程度的调查,分析影响MS病人治疗依从性的因素。1对象和方法1.1对象2003年6月—2005年6月我院内分泌科住院和门诊MS病人119例,均符合中华糖尿病学分会CDS(2004)MS诊断标准[2]。所有病人思维清晰,语言表…     

Nerve growth factor and tyrosine kinase A in human salivary adenoid cystic carcinoma: expression patterns and effects on in vitro invasive behavior.

PURPOSE: Perineural invasion is a frequent occurrence in salivary adenoid cystic carcinoma (ACC) and may prevent complete surgical resection. Studies have indicated that nerve growth factor (NGF) and its high-affinity receptor tyrosine kinase A (TrkA) may play a role in perineural invasion in several malignancies in which perineural invasion is observed. The present study was conducted to investigate the expression of NGF and TrkA in salivary ACC and to examine the effects of NGF on adhesion, migration and invasion capacities of a salivary ACC cell line (SACC-83) in vitro. PATIENTS AND METHODS: Expression of NGF and TrkA was explored using immunohistochemistry in paraffin-embedded tissues of 32 cases of salivary ACC. The effects of NGF on in vitro adhesion, migration, and invasion capacities of the SACC-83 cell line were examined using an MTT assay and a modified Boyden chamber assay respectively. RESULTS: In ACC specimens, 31 (96.9%) and 32 (100%) tumors showed immunoreactivity for NGF and TrkA respectively. Significant correlations were found between NGF/TrkA expression levels and perineural invasion (P < .05). In cell adhesion assay, the percent adherences of SACC-83 cells co-cultured with 25 ng/ml NGF at 1.5 hours and 5, 25 ng/ml NGF at 6 hours were significantly higher than that co-cultured with 0 ng/ml NGF (P < .05). However, high concentration of NGF (500 ng/ml) resulted in a significant inhibition of invasion (P < .05). CONCLUSION: Overexpression of NGF and TrkA in human salivary ACC tissues may constitute a reason for perineural invasion in salivary ACC.
