用单光子吸收法(SPA)对杭州市汉族50岁以上的80例非胰岛素依赖性糖尿病(NIDDM)患者和年龄、性别与NIDDM患者相配对的431名正常人的前臂尺、桡骨骨密度(BMD)进行测定,发现女性轻中型和重型组、男性重型组NIDDIM患者的尺桡骨平均BMD显著地低于正常人(P<0.01);本组NIDDM患者(男女合计)的一般性骨质疏松症(GOP)和进行性骨质疏松症(POP)的发病率分别为63.75%和8.75%,与正常人组相比较差异非常显著(P<0.01);不同病程NIDDM患者组别间尺桡骨平均BMD的差异不显著(P>0.05),提示NIDDM的病程与BMD的相关程度不密切。  相似文献

慢性肺心病患者血清TNF-α及IL-8改变及意义   总被引:3,自引:0,他引:3  
探讨了慢性肺心病(CPHD)急性加重期及经治疗缓解后血清白细胞介素-8(IL-8)和肿瘤坏死因子-α(TNF-α)水平的变化.用双抗体夹心ELISA法检测了30例CPHD患者急性加重期及治疗缓解后血清IL-8和TNF-α,并与相应年龄的健康对照组比较.结果发现CPHD患者急性加重期血清IL-8及TNF-α水平显著高于正常对照组(P<0.05),且治疗缓解后血清TNF-α水平显著降低(P<0.05),而血清IL-8水平则基本不变(P>0.05).说明IL-8、TNF-α参与了CPHD的发生和发展,这为探求治疗新途径提供了依据.  相似文献

Stroke is the third leading cause of death and foremost cause of disability. Based on studies in CAD patients, a focus has been shifted on genetic and inflammatory markers as risk factors for stroke besides deranged lipid profile. The present study was aimed to ascertain the role of Lipoprotein (a), C-Reactive protein (CRP) levels and lipids in patients of ischemic stroke. The study was done in 82 subjects including 40 Computerized Tomography (CT) proven patients of ischemic stroke and 42 age and sex matched controls. Complete biochemical parameters including lipid profile were carried out on autoanalyzer using standard kits and reagents. Lipoprotein (a) [Lp(a)] was determined by immunoturbidimetric assay. Atherogenic indices (Total cholesterol/ HDL, LDL/HDL and Lipid Tetrad Index) were calculated using these lipid parameters. The CRP levels were measured semi-quantitatively by latex agglutination test method. Out of 40 stroke patients, 38 had abnormalities in lipid profile (As per ATP III guidelines). A significant difference was seen in serum cholesterol, LDL cholesterol and atherogenic indices between the patients and controls. The difference in CRP levels in cases and control subjects was highly significant (4.78±0.72 mg/dl vs 0.76 ±0.70, p<0.001). 96.5% of patients with raised CRP had abnormal lipid levels also. CRP levels in stroke patients showed significant correlation with total cholesterol and LDL (p<0.001), Lp (a) (p=0.002) and atherogenic indices (p<0.05). Raised CRP levels in stroke patients were significantly associated with large territory infarcts, severe disability and poor functional outcome (p<0.05).Genetic [Lp(a)], metabolic (deranged Lipid profile) and inflammatory factors (CRP) together are instrumental in causing cerebrovascular arteriosclerosis leading to ischaemic stroke and can be used as important markers to identify patients at risk of severe stroke and to institute aggressive preventive strategies.  相似文献

The depth of anesthesia estimation has been of great interest in recent decades. In this paper, we present a new methodology to quantify the levels of consciousness. Our algorithm takes advantage of the fractal and self-similarity properties of the electroencephalogram (EEG) signal. We have studied the effect of anesthetic agents on the rate of the signal fluctuations. By translating these fluctuations with detrended fluctuation analysis (DFA) algorithm to fractal exponent, we could describe the dynamics of brain during anesthesia. We found the optimum fractal-scaling exponent by selecting the best domain of box sizes, which have meaningful changes with different depth of anesthesia.Experimental results confirm that the optimal fractal-scaling exponent on the raw EEG data can clearly discriminate between awake to moderate and deep anesthesia levels and have robust relation with the well-known depth of anesthesia index (BIS). When the patient's cerebral states change from awake to moderate and deep anesthesia, the fractal-scaling exponent increases from 0.8 to 2 approximately. Moreover, our new algorithm significantly reduces computational complexity and produces faster reaction to transients in patients’ consciousness levels compared to other algorithms and technologies.  相似文献

The present study was carried out in the Sahariya tribe of Central India, which reportedly have high prevalence of pulmonary tuberculosis. Total serum LDH and its tissue specific isoforms were estimated in TB patients and matched healthy controls to test the utility of LDH as diagnostic marker for tuberculosis. About 210 sputum positive cases and 328 age and sex matched sputum negative controls were recruited. The spectrophotometeric and densitometric analysis of each LDH isoform was carried out in both cases and controls. The mean values of serum LDH were estimated and compared for each class by t-test. The statistical comparisons were made between sputum negative controls and sputum positive cases by Mann-Whitney’s U test. The spectrophotometric estimation of serum LDH revealed significant (P=0.0016) increase in its level in cases (290 IU/L) as compared to controls (248 IU/L). The densitometric analysis of individual LDH isoforms in cases and controls demonstrated significant elevation in LDH1 (P>0.05), LDH2 (P>0.05) and LDH3 (P<0.005) in sputum positive cases in comparison to sputum negative controls. Our study revealed a positive correlation between serum LDH level and the presence of mycobacteria and their load, suggesting utility of LDH as an important diagnostic marker of tuberculosis induced stress, at least in tribal areas lacking access to modern clinical tests.  相似文献

Vitiligo is an idiopathic, acquired, circumscribed, hypomelanotic skin disorder, characterized by milky white patches of different sizes and shapes. It is due to the destruction of melanocytes resulting in the absence of pigment production of the skin and mucosal surfaces. Oxidative stress has been implicated in pathophysiology of vitiligo. To study the activity of blood Superoxide dismutase (SOD) and Glutathione peroxidase (GPx) in vitiligo patients. A case–control study was conducted in which 100 patients were enrolled after written consent. 50 cases were of active vitiligo and 50 served as control (25 healthy control and 25 with stable vitiligo). SOD—In our study, among the active vitiligo cases 90% had high level of SOD and 10% had normal level of SOD. Among the stable vitiligo controls, 92% had normal level of SOD and 8% had low levels of SOD.The difference between active vitiligo cases and stable vitiligo control as well as with healthy control was statistically significant (P value < 0.05). GPx—Among the active vitiligo cases 74% had normal GPx levels, 22% had low and only 4% had high levels of GPx. Among the stable vitiligo controls, 64% had normal GPx levels, 16% had low, and 20% had high levels of GPx. The difference between active vitiligo cases and stable vitiligo control as well as with healthy control was statistically not significant (P value > 0.05). Our study shows that oxidative stress is involved in the pathophysiology of vitiligo, as indicated by the high levels of serum superoxide dismutase activity.  相似文献
