Background/Aim: The Glutathione S-transferases (GSTs) are important carcinogen-metabolizing enzymes. Polymorphisms involved in these enzymes can modulate the development and treatment of head and neck cancer. To investigate the association of GSTs polymorphisms with head and neck cancer and risk factors, clinical-pathological features, and survival time of the patients treated with chemotherapy and/or radiotherapy. Methods: The GST gene polymorphisms were evaluated in 197 cases and 514 controls by PCR-RFLP-Polymerase Chain Reaction Restriction Fragment Length Polymorphism. Results: The GSTP-313 was associated with a decreased risk for HNSCC (p=0.050). The GSTP1 haplotype analysis revealed a higher frequency of the AC and AT haplotypes in the case group than in the control group (p=0.013 and p=0.019, respectively), and the opposite for G-C haplotype (p = 0.015). Yet, the different combinations between the genotypes were associated with an increased risk of cancer. The study showed no association between the polymorphisms and primary tumor site, clinical-pathological characteristics, treatment (chemotherapy and/or radiotherapy) and survival time of the patients. Conclusion: The GST polymorphisms combination showed an increased risk for carcinogenesis, and studies with larger casuistry can contribute to the clarification of the role in individual patient differences for the response to chemotherapy and/or radiotherapy and identify biomarkers of susceptibility.  相似文献

Background

Since recent reports have shown that (-)-Epigallocatechin-3-gallate (EGCG) could be used for treating proliferative and inflammatory disorders, we explored its use for the management of corneal chemical burns.

Materials and methods

Initially, EGCG was assayed on the rabbit corneal epithelial cell line RCE1(5T5) to establish the best testing conditions, and to avoid unwanted outcomes in the experimental animals. Then, we studied its effects on cell proliferation, cell cycle progression and cell differentiation. Afterwards, we instilled EGCG in experimental grade II corneal alkali burns in mice, three times a day up to 21 days, and evaluated by slit lamp examination and histological sections of corneal epithelial, corneal endothelial and stromal edema, as well as the presence of inflammatory cells and neovascularization.

Results

EGCG reduced cell growth and led to a decline in the proportion of proliferative cells in a concentration dependent manner. At 10 μM, EGCG promoted cell differentiation, an effect not related with apoptosis or cytotoxicity. When 10 μM EGCG was instilled in corneal alkali burns in mice three times a day up to 21 days, EGCG significantly reduced corneal opacity and neovascularization. The improved clinical appearance of the cornea was associated to a controlled epithelial growth; epithelial morphology was similar to that observed in normal epithelium and contrasted with the hyperproliferative, desquamating epithelium observed in control burn wounds. EGCG reduced corneal, stromal and endothelial edema, and wound inflammation.

Conclusion

This work constitutes the first evidence for the use of EGCG in the acute phase of a corneal alkali burn, representing a possible novel alternative to improve patient outcomes as an add-on therapy.  相似文献

Objectives

To analyze the factors associated with fatigue focusing on comorbidities in a large cohort of rheumatoid arthritis (RA).

Methods

Cross-sectional analyses were performed on RA patients from the French COMEDRA cohort study, a nurse-led program for comorbidities management. Fatigue was assessed using Question 3 of the Rheumatoid Arthritis Impact of Disease (RAID) score on a 0–10 numerical rating scale (NRS). Fatigue was defined as acceptable if?≤?2, moderate if 3 or 4, or severe if?≥?5 out of 10. Using univariate and multivariate models, the relationship between fatigue and demographics, social, disease characteristics, comorbidities (cardiovascular, infections, cancer, pulmonary, osteoporosis, and psychiatric disorders), physical activity, quality of life, and treatments was investigated.

Results

In total, 962 patients were analyzed. The mean fatigue score was 3.8?±?2.7, 40% of patients reported severe fatigue. Patients had an average of 1.8 additional morbid conditions, with anxiety/depression the most common (52%). In univariate analysis, severe fatigue was more frequent in women, in patients not working, and in those with less physical activity. It was associated with disease duration and activity, mHAQ, pain, sleeping and emotional difficulties. Severe fatigue correlated with Multimorbidity index assessing the number of morbid conditions and was associated with obesity, hypertension, COPD, and anxiety/depression. In multivariate models, the risk of severe fatigue was associated with female gender, disease activity, mHAQ, current treatment with NSAIDs and biologics, multimorbidity, obesity and anxiety/depression.

Conclusions

Assessment of comorbidities, psychological health and physical activity should be taken into account in order to address frequent RA-related severe fatigue.  相似文献
