目的探讨西藏拉萨地区幽门螺杆菌(Helicobacter pyloric,Hp)感染与冠心病及多种危险因素的关系。为该地区冠心病的防治提供依据。方法分为冠心病组46例和非冠心病组51例,应用检测血抗HpIgG及-C-尿素呼气试验方法检测Hp感染情况,并分别测定各组血脂、血糖、餐后2h血糖、C反应蛋白、纤维蛋白原、白细胞总数。结果冠心病组患者血清抗HpIgG阳性率为50.0%(23/46),明显高于非冠心病组的23.5%(12/51),P〈0.05;冠心病患者Hp现症感染率为54.3%(25/46),明显高于非冠心病组的31.3%(27/51),P〈0.05;冠心病组Hp感染患者血脂、空腹及餐后2h血糖、C反应蛋白、纤维蛋白原较非感染患者明显升高(P〈0.05)。结论Hp感染与冠心病相关,可能是拉萨地区冠心病发病的独立危险因素。 相似文献

We compared the tumor-initiating activities toward mouse skin of two
structurally related polycyclic aromatic hydrocarbon diol epoxides: racemic
anti-1,2,3,4-tetrahydro-5,6-dimethylchrysene-1,2-diol-3,4- epoxide
(5,6-diMeCDE) and racemic anti-1,2,3,4-tetrahydro-5-
methylchrysene-1,2-diol-3,4-epoxide (5-MeCDE). Tumors induced by these diol
epoxides were analysed for mutations in the Ha-ras gene. 5,6- diMeCDE is
derived from the non-planar parent compound 5,6- dimethylchrysene, and
reacts to approximately equal extents with dA and dG in DNA, whereas
5-MeCDE is derived from a nearly planar parent compound, 5-methylchrysene,
and reacts mainly with dG in DNA. 5,6- diMeCDE, at initiating doses of 33,
100 or 400 nmol per mouse, induced 1.2, 2.2 and 6.2 skin tumors per mouse,
respectively. It was significantly less tumorigenic than 5-MeCDE which
induced 3.1, 7.5 and 9.1 skin tumors per mouse at the same doses. Tumors
induced by 5,6- diMeCDE had a large number of CAA-->CTA mutations in
codon 61 of the Ha- ras gene: 50, 55 and 75% of the tumors analysed had
this mutation at the 33, 100 and 400 nmol doses. No mutations were found in
codons 12 and 13 in the tumors induced by 5,6-diMeCDE. In contrast,
CAA-->CTA mutations in codon 61 were rarely seen in tumors induced by
5-MeCDE. At the highest dose of 5-MeCDE, 20% of the tumors analysed had
mutations at G of codons 12 and 13. The results of this comparative study
support the hypothesis that mutations in the Ha-ras gene in mouse skin
tumors induced by PAH diol epoxides occur as a result of their direct
reaction with the gene. However, pathways other than the commonly observed
Ha- ras codon 61 mutations are clearly important in mouse skin
tumorigenesis by these diol epoxides.

目的:探讨随访2型糖尿病(T2DM)家系非糖尿病一级亲属5年的胰岛素抵抗和胰岛β细胞功能变化。方法:入选2型糖尿病家系非糖尿病一级亲属组(FDR)32例和正常对照组(NC)18例,基线检测了体质量指数、腰臀比、血压、血脂、血糖和空腹胰岛素(FINS)水平。采用稳态模式(HOMA)评价胰岛素抵抗(HOMA-IR)和胰岛β细胞功能(HOMA-β),5年后进行了相同的随访。结果:5年后FDR组HOMA-IR明显升高(P=0.040),HOMA-β明显降低(P=0.004)。5年后FDR组与NC组HOMA-IR组间无显著差异(P=0.594),HOMA-β明显降低(P=0.000)。多元逐步回归分析显示,FINS、空腹血糖(FBG)、高密度脂蛋白-胆固醇(HDL-C)是影响FDR组胰岛素抵抗的独立危险因素;FBG和FINS是影响FDR组胰岛β细胞功能的独立危险因素。结论:T2DM患者一级亲属非肥胖患者在发生糖尿病之前已经存在胰岛素抵抗和胰岛分泌功能缺陷,且随着病程延长胰岛β细胞功能衰竭可能更明显。 相似文献

目的:观察肌电生物反馈疗法结合部分减重平板运动疗法对脑卒中偏瘫患者下肢运动功能的影响。方法:脑卒中恢复期偏瘫患者40例随机分为治疗组和对照组各20例。两组患者均给予常规神经内科治疗、综合康复治疗及部分减重平板运动疗法,治疗组加用AM-800神经功能重建仪进行下肢肌电生物反馈疗法,共治疗4周。治疗前后进行功能评估,评估项目包括临床神经功能缺损评分、Fugl-Meyer评定、功能独立性评定(FIM量表)。结果:经治疗后,两组患者神经功能缺损评分均有下降,FIM量表得分及Fugl-Meyer下肢得分均上升,其中治疗组相比对照组神经功能缺损评分下降更显著,Fugl-Meyer下肢得分上升更显著(P均<0.05)。结论:肌电生物反馈疗法结合部分减重平板运动疗法,能有效改善脑卒中患者下肢运动功能,并可降低患者神经缺损程度。 相似文献

The risk factors for mortality were analysed in a consecutive group of 1158 children presenting to the Aga Khan University Medical Center, Karachi, with multidrug resistant typhoid fever that had been proved on culture. There were 19 deaths, representing an overall case fatality rate of 1.6%. Multidrug resistant typhoid was associated with a more severe clinical illness and higher rates of toxicity, hepatomegaly, hypotensive shock, and death. Irrespective of drug resistance status, typhoid fever was found to be a more severe illness in young infants with significantly higher rates of diarrhoea, hypotensive shock, and mortality. Univariate analysis of admission characteristics associated with increased risk for mortality revealed significant association with younger age (p < 0.05), hypotensive shock or hypothermia (p < 0.001), obtundation (p < 0.001), seizures (p < 0.05), anaemia at admission (p < 0.005), and leucocytosis (p < 0.001). Logistic regression analysis of risk factors for mortality showed persistent association of hypothermia, toxicity, and anaemia with mortality. The data provides evidence that multidrug resistant typhoid in childhood is associated with increased risk of mortality, especially in infancy and closer attention to several risk factors for increased morbidity and case fatality rates may lead to improved outcome of treatment. 相似文献

Twenty-four adults with ALL were treated with AMSA alone or in combination. Twenty-two were treated at time of relapse and two patients after failing primary induction therapy. All had been treated with anthracyclines prior to receiving AMSA. Of the 22 patients with ALL in relapse, 4 achieved a complete remission. Two of these patients have relapsed while receiving maintenance chemotherapy; one died 1 mo after achieving remission due to the occurrence of cholycystitis in the setting of pancytopenia and one patient underwent bone marrow transplantation and is in remission at 8 mo after the second remission. Both patients who failed primary induction therapy remain in remission at 11 and 36 mo, respectively. The use of AMSA should be considered for patients with ALL who fail primary induction as well as those whose leukemia becomes resistant to conventional agents. 相似文献
