中老年高尿酸血症预防知识与行为状况的调查研究

[目的]通过对中老年高尿酸血症的预防知识与行为状况的调查，分析预防护理知识缺乏的原因。[方法]2003年1月-2005年2月来我院查体与就诊者年龄在40岁以上的中老年人685例，分为高尿酸组123例，非高尿酸组562例，进行血压（BP）、血尿酸（URIC）、体重指数（BMI）、空腹血糖（GLU）、血清胆固醇（CHOL）、三酰甘油（TG）、血尿素氮（BUN）、肌酐（CREA）等指标对比观察。同时采用问卷调查方法，对123例高尿酸血症者进行预防护理知识与行为状况的调壶分析。[结果]在685例调查者中有123例（17．96％）血尿酸高，在高尿酸血症组中，有半数以上人员对血尿酸高的相关知识认识不足，有近半数人员对高尿酸血症发展预后了解不足，自我护理行为缺乏。另与高尿酸血症同时并存的还有肥胖、高血压、高血脂、高血糖。[结论]中老年高尿酸血症发生率在升高，疾病知识缺乏，自我护理意识不强，应加大对高尿酸血症发生发展的教育力度，以使其建立健康的生活习惯，减少痛风的发生。     

慢性肾衰竭急性加重的临床特征及相关因素分析

目的：探讨慢性肾衰竭（CRF）急性加重因素及其治疗措施对预后的影响。方法：对2001年1月～2005年6月住院治疗的CRF急性加重患者42例，按其加重原因、基础疾病、治疗方式和疗效进行回顾性总结。结果：CRF急性加重因素依次为各种感染（45．2％）、原发病加重（19．0％）、高血压未控制（14．3％）、水电解质紊乱（11．9％）、肾毒性药物（11．9％）、心功能不全（9．5％）、尿路梗阻（4．8％）、血高粘滞状态（2．4%），7例同时存在≥2种上述病因（16．7％）。CRF急性加重原发病以慢性肾小球肾炎（52．4％）和糖尿病肾病（11．9％）为主。积极治疗后肾功能恢复达到或接近原来水平者40例，死亡2例，死亡2例的年龄均在60岁以上。结论：对于CRF肾功能急剧恶化的患者，应积极寻找其加重因素，并采取非透析和透析相结合治疗，改善肾功能，降低病死率，延长患者生命。

Acute disseminated encephalomyelitis: the importance of early magnetic resonance imaging

The diagnosis of acute disseminated encephalomyelitis (ADEM) is frequently missed or delayed with consequent delay in instituting therapy in the crucial phase of the illness. The role of MRI in the diagnosis of ADEM is well established, however, the value of its early utilization of treatment on the outcome of patients has not been adequately stressed. Three patients with ADEM are described. Delay in the diagnosis of the first was associated with severe sequelae, while in the other two early diagnosis and institution of corticosteroid therapy which was facilitated by MRI, was associated with a better outcome. MRI should be carried out early once the diagosis of ADEM is entertained.     

Neonatal renal failure due to obstructive candidal bezoars

Acute renal failure (ARF) developed in a 7-week-old infant due to bilateral candidal bezoars (fungal balls) causing obstruction at the pelviureteric junction. The baby was born at term with an appropriate birthweight, and had been treated with broad-spectrum antibiotics for respiratory distress and septicemia during the 1st week of life. Recovery from ARF followed renal decompression with bilateral nephrostomy tube placement and parenteral administration of amphotericin B and 5-flucytosine.

白血病细胞p16基因突变分析

目的探讨ｐ１６基因突变在白血病发生中的作用及基因突变的机制。方法利用点突变检测仪、水平和垂直板电泳对ｐ１６基因的外显子１、外显子２的ＰＣＲ扩增产物作缺失和点突变分析。结果在白血病３５例临床标本中有２２例发生缺失突变，６例发生点突变，突变率约８０％。在２２例缺失突变病例中，有１０例为不完全缺失突变即有低于外显子５０９ｂｐ的扩增产物。结论ｐ１６基因含有“ＧＣ”ＤＮＡ重复顺序，易发生ＤＮＡ重组及易位和重排。在白血病发生中起重要作用     

急性脑血管病患者血清髓鞘碱性蛋白含量研究

用酶联免疫吸附法对３０例急性脑血管病（ＣＶＤ）患者及３２位正常人血清髓鞘碱性蛋白（ＭＢＰ）含量进行检测。结果表明：急性ＣＶＤ组患者血清ＭＢＰ含量显著高于正常人组（Ｐ＜０．０１）；血清ＭＢＰ含量与急性ＣＶＤ的严重程度相关。提示检测血清ＭＢＰ含量对急性ＣＶＤ诊断及预后判断有重要价值     

Effects of capsaicin in temporomandibular joint arthritis in rats

Temporomandibular joint (TMJ) arthritis was induced in female Lewis rats by unilateral injection of a suspension of heat-killed Mycobacterium butyricum in paraffin oil into the TMJ. Control rats received paraffin oil by the same route. Arthritic and control rats were pretreated either with capsaicin or denervation of the mandibular branch of the trigeminal nerve. Tissues were collected for neuropeptide extraction and analysed by radioimmunoassay and reverse-phase high-performance liquid chromatography. In all groups, the levels of substance P- (SP), calcitonin gene-related peptide- (CGRP) and neuropeptide Y- (NPY) like immunoreactivity (LI) were higher in the trigeminal ganglia than in the TMJs. In control rats, capsaicin significantly lowered the levels of SP-LI in the trigeminal ganglia and TMJ, but not CGRP-LI and NPY-LI. In the arthritic rats, capsaicin pretreatment significantly lowered the SP-LI and CGRP-LI in the trigeminal ganglia and TMJ, but not the NPY-LI. In the trigeminal ganglia the unilateral denervation significantly lowered SP-LI in control rats, and in arthritic rats SP-LI and CGRP-LI. On the denervated side of the arthritic TMJ, NPY-LI, SP-LI and CGRP- LI were significantly lowered as compared to the arthritic control rats and to the contralateral side. In this rat model, pretreatment with capsaicin and surgical denervation decreased the neuropeptide content in the trigeminal ganglia and the TMJ. The results clearly demonstrate a close interaction between increased neuropeptide release from sensory and sympathetic neurones after induction of arthritis in the rat.
