Arsenic trioxide (As2O3) is a promising new regimen for the treatment of acute promyelocytic leukemia (APL). The induction of oxidative stress mediated by reactive oxygen species (ROS) and excessive intracellular calcium influx are the main reasons behind As2O3 toxicity. Since liver is the major organ for xenobiotic metabolism, it is always under stress. Antioxidant vitamins such as L-Ascorbic acid (L-AA) and α-Tocopherol (α-TOC) have been proposed to have beneficial effects against a variety of pathological conditions and are known by their free radical scavenging properties. The present study evaluates the curative efficacy of L-AA and α-TOC against As2O3 toxicity using immortalized human Chang liver cells. Our results suggest that L-AA (100 µM) and α-TOC (50 µM) recovered As2O3 (10 µM) cytotoxicity. Furthermore, As2O3 treatment showed an increase in lipid peroxidation and depletion in antioxidant status, mitochondrial trans membrane potential and values of total antioxidant capacity. Cotreatment of antioxidant vitamins with As2O3 resulted in a significant reversal of oxidative stress markers. Our findings substantiate the effect of antioxidant vitamins in protecting the hepatocytes from oxidative stress which may be attributed through Nrf2 (Nuclear factor erythroid 2-related factor 2) mediated upregulation of Bcl2 (B-cell lymphoma 2) expression. 相似文献

Liver transplantation (LT) is an important component in the therapeutic armamentarium of managing end-stage liver disease. In North American children, biliary atresia remains the most common indication for LT compared to hepatitis C in adults, while hepatoblastoma is the most common liver tumor requiring LT, versus Hepatocellular carcinoma in adults. Rejection, lymphoproliferative disease, renal insufficiency, metabolic syndrome, recurrent disease, ‘de novo’ autoimmune hepatitis and malignancy require careful surveillance and prompt action in adults and children after LT. In children, specific attention to EBV viremia, growth, development, adherence and transition to the adult services is also required. Antibody mediated rejection and screening for donor specific antibodies is becoming important in managing liver graft dysfunction. Biomarkers to identify and predict tolerance are being developed. Machine perfusion and stem cells (iPS) to synthesize organs are generating interest and are a focus for research. 相似文献

Methods:This single-center retrospective chart review included patients 21 years of age and younger with a preoperative diagnosis of appendicitis who underwent laparoscopic appendectomy from January 2010 through December 2015. Cases of gangrenous and perforated appendicitis were excluded. Subgroup analyses of patients with acute appendicitis were performed. Operative time (OT), length of stay (LOS), and cost were compared between groups stratified by body mass index (BMI) and operative technique.Results:A total of 625 appendectomies were performed—457 for acute appendicitis. Sixty-eight patients were overweight. The SP technique (n = 30) had shorter OT (median minutes, 41 vs 68; P < .001), lower cost (median , $5741 vs $8530; P < .001), and shorter LOS (median hours, 16 vs 19; P = .045) than the TP technique had (n = 38). Seventy patients were obese: 19 were treated with SP and 51 with TP. LOS did not differ significantly between the SP and TP groups, but subjects treated with SP had shorter OT (median minutes, 39 vs 63; P < .001) and lower cost (median, $6401 vs $8205; P = .043).Conclusions:The SP technique for acute appendicitis was found to have a significantly shorter OT and lower cost in all weight groups. There were minimal differences in LOS. SP should be considered in patients with acute appendicitis, regardless of their weight. 相似文献

Although not all patients develop progressive liver disease, chronic hepatitis B and chronic hepatitis C infections cause substantial morbidity and mortality worldwide. To address this need, many new antiviral treatments have become available over the past 10 years. While safety, efficacy, and therapeutic indications have been well established for these agents, the economics of antiviral treatment have become increasingly a focus of discussion for physicians, policymakers, and health payers. In this paper, we will elucidate some economic principles using examples from the treatment of hepatitis B and C. In particular, we will examine the considerations in estimating drug costs, methods for performing economic analyses and lastly summarize published cost-effectiveness analyses for antiviral treatments of chronic hepatitis B and chronic hepatitis C. This review should help clinicians understand economic issues regarding new drugs and answer questions about whether the clinical benefit provided by a medication justifies its expense. 相似文献

Tooth resorption is a perplexing problem for all dental practitioners. The etiologic factors are vague, the diagnoses are educated guesses and, often, the chosen treatment does not prevent the rapid disappearance of the calcified dental tissues. This becomes all the more confusing if the tooth in question is a pulpally involved young permanent tooth. Presented in this report is the case of an upper first young permanent molar that underwent complete root resorption following root canal therapy and obturation. 相似文献

Perforating injuries of the orbit involving the paranasal sinuses are uncommon. We report a case in which a large wooden foreign body lodged in the posterior orbit and maxillary sinus was surgically removed by a combined approach by ophthalmologists and ear, nose and throat surgeons. 相似文献

We report a 16-year-old morbidly obese African-American female who developed pseudotumor cerebri, partially empty sella syndrome and transient central hypothyroidism. After reduction of the increased intracranial pressure by lumbar puncture, normalization of the thyroid function occurred. The mechanism of the transient pituitary dysfunction in relation to the pseudotumor cerebri and empty sella is discussed. 相似文献

The aim of this study was to investigate whether there is an association between temperament characteristics of preschool children, dental anxiety, and their dental behaviour. A total of 100 children, aged 3–5 yr, who were attending their initial dental visit accompanied by a parent, were included in this cross‐sectional study. Dental anxiety of children was measured using the Facial Image Scale. The behaviour of children during the initial oral examination and oral prophylaxis was assessed using Frankl's behaviour rating scale. Temperament was assessed using Emotionality, Activity, Shyness Temperament Survey for Children (parental ratings). Statistically significant weak linear positive correlations were seen between the following: the percentage duration of definitely negative behaviour and shyness scores (rs = 0.28); anxiety level and emotionality scores (rs = 0.28); and anxiety level and shyness scores (rs = 0.26). Multinomial logistic regression analysis revealed that children with higher anxiety had higher odds of showing definitely negative behaviour, which decreased with increasing age of the child. Emotionality and shyness temperaments may be weakly associated with dental anxiety, and shyness may be weakly associated with the dental behaviour of the preschool child. Definitely negative dental behaviour is associated with dental anxiety and age of the child. 相似文献
