Citrate is commonly used as an anticoagulant in hemodialysis for chronic renal failure (CRF) and for the regulation of the immune dysfunction in CRF patients. The objective of this study was to investigate the effect of citrate on the balance of T helper 17 (Th17) and regulatory T (Treg) cells in CRF. The levels of blood urea nitrogen (BUN) and serum creatinine (Scr) were significantly increased in the CRF model group compared to the control group, and were decreased in the citrate-treated groups. Citrate treatment inhibited the viability of Th17 cells while elevating the viability of Treg cells in CRF rats. Moreover, Th17-related cytokines significantly decreased while the Treg-related cytokines significantly increased with citrate treatment. Moreover, citrate had a negative influence on the deviation of Th17/Treg cells in CRF rats. Therefore, our study suggests that citrate had an anti-inflammatory effect on CRF through the modulation of the Th17/Treg balance. © 2015, Springer Science+Business Media New York. Source

The study is to investigate the importance of early diagnosis and treatment to the prognosis of epilepsy with continuous spikes and waves during slow sleep (CSWS). A total of 8 cases of CSWS children were followed up for 6 months to 4 years. Retrospective analysis of the clinical and electroencephalographic (EEG) characteristics, treatment and prognosis was performed in these 8 cases. Of the 8 cases of CSWS patients, 5 were males and 3 were females. Epilepsy onset ages were from 3 years and 1 month to 10 years and 6 months. Five cases of the patients were with brain lesions while the other 3 cases appeared normally by imaging detection. After treatment with valproic acid, clonazepam, lamotrigine and hormone for 3 months, clinical symptoms and EEG were improved significantly in 7 cases. Two cases relapsed at 6 months after comprehensive treatment. For atypical early performance of CSWS, early diagnosis and regular treatment could improve the condition of children with seizures and effectively inhibit the epileptic activity with good prognosis. © 2015, Int J Clin Exp Med.

The aim of this study was to investigate the therapeutic effect of Angelica sinensis on a rat model of diffuse interstitial pulmonary fibrosis induced by bleomycin A5. The mechanism by which A. sinensis exerts its effect is also discussed. A diffuse interstitial pulmonary fibrosis model was established in 36 male Wistar rats by an endotracheal injection of bleomycin A5 (5 mg/kg). Then, these rats were randomly divided into the model group (n = 18) and the treatment group (treated with A. sinensis after modelling, n = 18). Control rats (n = 6) received an equal volume of saline. Hematoxylin–eosin (HE) staining was performed to analyse alveolitis and Masson staining, to observe pulmonary fibrosis. Collagen content was determined by hydroxyproline assay. Nuclear factor kappa B (NF-κB) activity was measured by electrophoretic mobility shift assay. Transforming growth factor-β (TGF-β) expression at mRNA level was detected by northern blotting and at protein level by enzyme-linked immunosorbent assay. The results obtained showed that the alveolitis and pulmonary fibrosis of the rats treated with A. sinensis was significantly alleviated compared with that of the rats in the model group. Treatment with A. sinensis also lowered the content of collagen, decreased NF-κB activity in alveolar macrophages and reduced the TGF-β expression at the mRNA and protein level. These results indicated that A. sinensis is effective in treating and alleviating interstitial pulmonary fibrosis, possibly by lowering collagen, inhibiting the activity of NF-κB and reducing the TGF-β expression. © 2014 The Author(s).

Purpose: We aimed to investigate the expression of EGFR and the autophagy-related markers Beclin1 and LC3 in cervical cancer. Methods: Beclin1, LC3, and EGFR expression were analyzed in 80 samples of cervical squamous cell carcinoma (SCC), 40 samples of high-grade cervical intraepithelial neoplasia (CIN), and 40 samples of normal cervical tissues by immunohistochemistry. The protein expression rates were analyzed with χ2 and Fisher’s exact tests. Differences in overall survival (OS) were determined using the Kaplan–Meier method and log-rank tests. Results: Cervical cancer, high-grade CIN, and normal cervical epithelial cells expressed Beclin1 in 26.2%, 77.5%, and 82.5% of patients, respectively, and expressed LC3 in 28.8%, 70.0%, and 75.0% of patients, respectively. There was a significant difference between cervical SCC and high-grade CIN or normal cervical epithelial cells (P=0.000). Cervical cancer cells, high-grade CIN cells, and normal cervical epithelial cells expressed EGFR in 68.8%, 62.5%, and 12.5% of patients, respectively. There was a significant difference between cervical SCC or high-grade CIN and normal cervical epithelial cells (P=0.000). No significant association between Beclin1 or LC3 or EGFR expression and various clinicopathological parameters was observed in cervical SCC. There was no significant correlation between Beclin1, LC3, EGFR expression, and 5-year OS rates of cervical SCC patients. Beclin1- or LC3-negativity with EGFR-positivity in cervical SCC was associated with a higher Federation International of Gynecology and Obstetrics (FIGO) stage (P=0.011 and P=0.013, respectively) and pelvic lymph node metastasis (P=0.036 and P=0.092, respectively). The 5-year OS rates did not significantly differ between Beclin1- or LC3-positive and -negative patients with positive EGFR. Conclusion: Autophagy was downregulated and EGFR was upregulated in cervical SCC. Autophagy downregulation combined with EGFR upregulation promotes the progression of cervical SCC. © 2015 Hu et al.

Objective: The purpose of this review is to discuss some critical issues of isoflavones protective against the development of prostate cancer (PCa). Data Sources: Data cited in this review were obtained primarily from PubMed and Embase from 1975 to 2015. Study Selection: Articles were selected with the search terms “isoflavone”, “Phytoestrogen”, “soy”, “genistin”, and “PCa “. Results: Isoflavones do not play an important role on prostate-specific antigen levels reduction in PCa patients or healthy men. The effect of isoflavones on sex hormone levels and PCa risk may be determined by equol converting bacteria in the intestine, specific polymorphic variation and concentrations of isoflavones. The intake of various types of phytoestrogens with lower concentrations in the daily diet may produce synergistic effects against PCa. Moreover, prostate tissue may concentrate isoflavones to potentially anti-carcinogenic levels. In addition, it is noteworthy that isoflavones may act as an agonist in PCa. Conclusions: Isoflavones play a protective role against the development of PCa. However, careful consideration should be given when isoflavones are used in the prevention and treatment of PCa. © 2016 Chinese Medical Journal. Source
