Review of non‐positron emission tomography functional imaging of primary musculoskeletal tumours: Beyond the humble bone scan

Bone and soft tissue tumours are rare neoplasms. There are five major roles of imaging in the management of primary musculoskeletal tumours, that is, to differentiate between benignity and malignancy, to evaluate for local tumour extension, to screen for metastases, to judge the effect of chemotherapy, and to monitor for recurrence. To accomplish this, multiple modalities are required because no single examination is able to complete all these tasks. These modalities include plain radiography, CT, MRI, conventional nuclear medicine as well as positron emission tomography (PET) imaging. Elsewhere, PET imaging has been discussed at length, because it is likely to be superior in the assessment of bone and soft tissue tumours over conventional nuclear medicine procedures. However, conventional nuclear medicine may be of value when PET is unavailable. In this review, an overview of anatomical imaging will be given and the role of non‐PET functional imaging will be discussed in detail. A variety of illustrative cases will be presented.     

IL-2对精子顶体酶及一氧化氮合酶活性的影响

目的　探讨白细胞介素 2对正常人及白细胞精子症精子功能的影响。方法　精子顶体酶的活性检测采用BAEE/ADH联合法。结果　白细胞精子症及正常人精子顶体酶的活性分别为 (2 7.6 8± 10 .0 6mU/ml,n =18;4 3.6 3± 7.6 1mU/ml,n =18) (P <0 .0 1) ;白细胞精子症及正常人精子一氧化氮合酶分别为 (2 .74± 0 .39U/mg pr,n =18;2 .74± 0 .39U/mgpr,n =18) (P <0 .0 1)。结论　白细胞介素 2对精子顶体酶和一氧化氮合酶均有明显抑制作用 ,提示这可能是导致精子受精能力下降的原因。

严重继发性甲状旁腺功能亢进症临床分析

目的调查血液透析患者全段甲状旁腺激素（iPTH）、血清钙和血清磷的水平，了解严重的继发性甲状旁腺功能亢进症（SHPT）的发病情况。方法选择血液透析治疗超过1年，行3次以上iPTH、Ca和P检查的患者，以血iPTH〉800ng／ml为界定点，分析严重的SHPT发病率与年龄、性别、透析龄、原发病（糖尿病或非糖尿病）、血清钙和血清磷的关系。结果139例患者中有27例是严重的SHPT患者，发病率为19．4％（27／139），它们拥有较长的透析龄（P〈0．05）；其糖尿病的发生率明显低于非糖尿病（P〈0．05），而且存在明显的高磷血症和高钙磷乘积（P〈0．05）。Logistic回归分析显示，年龄、高钙磷乘积是严重的SHPT的独立危险因素（P〈0．05）。结论严重的SHPT的发病率与年龄、高钙磷乘积有关。因此，临床上必须早治疗，严格控制高磷血症。     

表面活性剂在硝酸士的宁注射液酸性染料比色法中的应用

表面活性剂在光度分析中已经有了广泛的应用,不论是在水溶液中测定的胶束增溶光度法还是在有机溶剂中测定的胶束萃取光度法中,表面活性剂的加入都具有明显的增溶、增敏和增稳作用,它能直接影响显色反应的速度、平衡位置以及配合物的构型,能改变溶剂的

在非溃疡性消化不良中ELISA法测抗幽门螺旋杆菌抗体的临床意义

非溃疡性消化不良(NUD, non-ulcer dyspepsia)是常见症候群,其病因尚未完全明了。NUD中幽门螺旋杆菌(HP Helicobacter Pylori)相关性胃炎占很大比例。针对该菌产生之抗体反应,应用酶联免疫法(ILISA)检测了335例NUD患者血清抗-HP抗体。其中208例为经细菌培养及(或)组织学检查证实的HP相关性胃炎,对其中164例进行前瞻性随机安慰剂对照研究,以评价胶态次枸橡酸铋加氟哌酸治疗效果.治疗组与安慰剂组HP清除率分别为69％与6％(P<0.01)。HP清除后患者胃粘膜炎症好转或消除,症状明显减轻,抗-HP抗体滴度下降。     

Surgical Management of PICA Aneurysm and Incidental Facial Nerve Schwannoma: Case Report.

We report a patient with a posterior inferior cerebellar artery (PICA) aneurysm and an incidental facial nerve schwannoma at the cerebellopontine angle (CPA). A 46-year-old woman presented with the sudden onset of a severe headache, nausea, and vomiting. She had no other abnormal neurological symptoms and signs. Computed tomography (CT) showed hemorrhage in the fourth ventricle. Cerebral angiography demonstrated an aneurysm arising from the tonsillomedullary segment of the left PICA. A facial nerve schwannoma was incidentally found as the aneurysm was being clipped. The aneurysm was clipped via a left transcondylar approach. Subsequently, the schwannoma (2 x 3 x 2 mm) was resected from the facial nerve fascicles, and the facial nerve was preserved. Postoperatively, the patient developed mild to moderate dysfunction of the facial nerve (House-Brackmann grade III [H-B III]) but her hearing was intact. Both a facial nerve schwannoma involving the CPA and an aneurysm involving the PICA can be managed through the transcondylar approach. An asymptomatic facial nerve schwannoma can be resected safely with minimal facial nerve dysfunction.
