心内直视手术后,因病情需要,常继续保留一段时间的人工辅助呼吸。气管内插管及插管时间较长可导致口腔、咽喉等部位黏膜损伤、细菌感染,同时,由于长时间使用抗生素导致菌群失调,免疫力下降,甚至可出现双重感染。因此,对术后病人勤加观察,做到早发现、早治疗,降低或防止口腔并发症的发生。本文报告心内直视术后几种常见口腔并发症的早期表现和治疗体会。 相似文献

Mild haemorrhage occasionally causes delayed death following failure of kidney or multiple organs, but the precise mechanisms have not yet been identified. We investigated the role of tumour necrosis factor-alpha (TNF-alpha), known as a major pro-inflammatory cytokine that leads to multiple organ failure, on the renal damage induced by mild haemorrhage. A mild haemorrhagic state was induced in male anaesthetized rats by bleeding via a common carotid catheter for 20 min at 16.7% of total body blood, 1.09 ml/100 g body weight, without fluid resuscitation. Mean arterial pressure and heart rate decreased soon after haemorrhaging but returned to baseline level up to 5 h after bleeding. TNF-alpha mRNA expression in the kidney and serum TNF-alpha levels were highest at 1 h after bleeding. Intraperitoneal pretreatment with FR167653, an inhibitory compound of TNF-alpha production, as well as of interleukin (IL)-1beta, significantly inhibited the increase in TNF-alpha. The inflammatory cell infiltration and tubular cell injury induced by haemorrhage were suppressed, and the renal dysfunction was dramatically improved by the FR167653 treatment. The morphological changes were also less in the treated group than in those that had not been treated. TNF-alpha has been reported to have striking effects on IL-1beta release and activation of neutrophils, and to play a pivotal role in the expression of the other pro-inflammatory cytokines. Our data show that endogenously-derived TNF-alpha does play a key role in the renal dysfunction during mild haemorrhage. These results should be useful to forensic pathologists to explain the pathogenesis of renal dysfunction induced by a mild haemorrhage and to identify the cause of death where there are no significant morphological changes after mild haemorrhage. 相似文献

Macrophages are involved in the development and progression of kidney fibrosis. The aim of this study was to analyse the phenotype of circulating monocytes and their ability to predict kidney allograft dysfunction in living kidney transplant recipients. Whole blood samples from 25 kidney recipients and 17 donors were collected at five time‐points. Monocyte phenotype was analysed by flow cytometry, and interleukin (IL)‐10 and soluble CD163 by enzyme‐linked immunosorbent assay. One week after transplantation, surface CD163 and IL‐10 levels increased significantly from baseline [2·99 ± 1·38 mean fluorescence intensity (MFI) to 5·18 ± 2·42 MFI for CD163; 4·5 ± 1·46 pg/ml to 6·7 ± 2·5 pg/ml for IL‐10]. This CD163 increase correlated with 4‐month creatinine levels (r = 0·4394, P = 0·04). However, soluble CD163 decreased significantly from baseline at 1 week (797·11 ± 340·45 ng/ml to 576·50 ± 293·60 ng/ml). CD14+CD16– monocytes increased at 4 months and correlated positively with creatinine levels at 12 and 24 months (r = 0·6348, P = 0·002 and r = 0·467, P = 0·028, respectively) and negatively with Modification of Diet in Renal Disease (MDRD) at 12 months (r = 0·6056, P = 0·003). At 4 months, IL‐10 decreased significantly (P = 0·008) and correlated positively with creatinine at 2 years (r = 0·68, P = 0·010) and with CD14+CD16– monocytes at 4 months (r = 0·732, P = 0·004). At 24 h, levels of human leucocyte antigen D‐related declined from 12·12 ± 5·99 to 5·21 ± 3·84 and CD86 expression decreased from 2·76 ± 1·08 to 1·87 ± 0·95. Both markers recovered progressively until 12 months, when they decreased again. These results indicate that monitoring monocytes could be a promising new prognostic tool of graft dysfunction in renal transplant patients. 相似文献

Background and Aim:
It is well known that dialysis dependent renal failure increases the likelihood of poor outcome following cardiac surgery. But the results of CABG in patients with mild renal dysfunction are not clearly established. The aim of the study is to analyze the risk of preoperative mild renal dysfunction on outcome after isolated coronary surgery.Materials and Methods:
We reviewed prospectively collected data between June 2006-Nov 2006 in 488 patients who underwent isolated CABG. We separated the data into two groups. Control group having normal renal function and study group having mild renal dysfunction (serum creatinine 1.4 mg-2.2 mg%). Among 488 patients, 412 patients were in control group and 76 patients were in the study group.Results:
Analysis of data showed significant postoperative complications in the mild renal dysfunction group, like increased operative mortality (7.5% vs 1.6%), increased requirement of postoperative renal replacement therapy (10% vs 1.2%), increased incidence of new onset atrial fibrillation (20% vs 4.2%) and prolonged duration of ICU stay. Multivariate analysis adjusting for known risk factors confirmed preoperative mild renal dysfunction (S.creat.1.4-2.2 mg/dl) is an independent risk factor for postoperative morbidity and mortality. (Adj. OR: 4.47; 95% CI: 1.41-14.16; P=0.010).Conclusion:
Mild renal dysfunction is an important independent predictor of outcome in terms of in-hospital mortality and morbidity in patients undergoing CABG. 相似文献14.

The pain of transvenous cardioversion shocks in awake patients is an important clinical problem. It is unknown whether psychological factors modulate any observed variation in pain perception. Thirty-seven patients with chronic atrial fibrillation (AF; mean age 61.9 years, 29 men, 8 women) were consecutively included in the study. Pain perception of a low energy test shock (60V, 0.1J) during internal cardioversion was assessed immediately following the stimulus. Before treatment anxiety, depression, somatization were evaluated. The intracardiac shock was perceived as hypalgesic in 15 (41%) patients, as normalgesic in 10 (27%), and as hyperalgesic in 10 (32%) patients. Pain threshold was significantly lower in patients in which AF was accidentally diagnosed (p < 0.029). Age, sex, and the level of education were equally distributed over the three pain groups. The hyperalgesic pain threshold was not associated with anxiety, depression, or the patients' tendency to amplify benign bodily sensations. This study discloses a wide range of perceived pain intensity caused by a homogenous intracardiac stimulation. Anxiety and depression do not amplify perception of intracardiac shocks. Sensory gating mechanisms may play a more important role in the level of intracardiac shock perception than distressing affective factors. 相似文献

BackgroundDyslipidemia has been associated with endothelial dysfunction in childhood. Impairment of renal function has been demonstrated in dyslipidemic adults.ObjectiveThe aim of this study was to assess markers of early endothelial and renal dysfunction in dyslipidemic children.MethodsThis was a cross-sectional study of 100 children with dyslipidemia and 100 age- and sex-matched control subjects without dyslipidemia aged 7–16 years. Renal dysfunction was assessed by measurement of serum creatinine and cystatin C levels, urinary beta 2-microglobulin levels, urinary albumin to creatinine (Alb:Cr) ratio, and by the estimated glomerular filtration rate (eGFR), based on serum creatinine or cystatin C. Endothelial dysfunction and early vascular changes were evaluated by ultrasound assessment of flow mediated dilation (FMD) of the brachial artery, and carotid intima-media thickness (cIMT), respectively.ResultsThe markers of early renal dysfunction showed no difference between the dyslipidemic children and control subjects except for the urinary Alb:Cr ratio that was higher in the dyslipidemic children (median, 0.007 mg/mg vs 0.005 mg/mg, p = 0.004). The urinary Alb:Cr ratio was positively correlated with the triglyceride to high-density lipoprotein cholesterol ratio (r = 0.28, p = 0.013). FMD values were lower in the dyslipidemic children than in the control subjects (8.504 ± 4.73% vs 10.535 ± 4.35%, p = 0.004), but cIMT did not differ between groups. This decrease in FMD values was evident in children aged ≥10 years. FMD was independently associated with the level of lipoprotein (a) (beta = ?0.29, p = 0.01).ConclusionAmong markers of endothelial and renal dysfunction investigated, FMD was found to be lower and the urinary Alb:Cr ratio higher in children with dyslipidemia. 相似文献

This study aimed to investigate how the impairment of the olfactory system influences interoception. Interoception is known as the awareness of one's body or the sense of the condition of the body; more precisely, this construct is defined as the processing, representation, and perception of the internal physical state. Interoceptive sensitivity and chemosensory performance were assessed in 77 subjects, including 43 functional anosmics, 18 hyposmics, and 16 healthy controls. Interoceptive awareness was predicted by odor detection threshold, as well as the duration of olfactory loss in patients who suffered from reduced olfactory function—the longer the olfactory impairment, the worse the perception of bodily signals. The results of this study will significantly contribute to the basic understanding of the multifaceted effects of olfactory alterations. 相似文献

Introduction: Clear cell renal cell carcinoma (ccRCC) is the most common type of cancer in the adult kidney, and the prognosis of metastatic ccRCC remains poor with high mortality. Recent study indicated that microRNAs (miRNAs) played critical roles in tumor progression. The aim of this study was to investigate the expression, biological role and clinical significance of miR-497 in ccRCC. Methods: Quantitative real-time PCR (qRT-PCR) was performed to detect the expression of miR-497 in renal cancer cell lines and ccRCC tissues. The association between miR-497 expression and overall survival was estimated by the Kaplan-Meier method. Gain of function assays were performed in the 786-O renal cancer cell line. Results: Expression of the miR-497 was significantly decreased in renal cancer cell lines and ccRCC tissues when compared with normal human proximal tubule epithelial cells and adjacent non-tumor tissues. Decreased miR-497 expression was significantly associated with tumor stage, histological grade and lymph node metastases. Significantly shorter overall survival was observed in patients with lower expression of the miR-497. Overexpression of miR-497 significantly inhibited renal cancer cell proliferation, migration and invasion. Conclusions: Our results demonstrated that miR-497 was decreased in ccRCC tissues and may provide a potential prognostic biomarker and a potential target for therapeutic intervention. 相似文献
