OBJECTIVE: To explore the role of Th17 cells, CD4⁺ CD25⁺ regulatory Treg cells (Treg) and its transcription factor RORγt and FoxP3 in the pathogenesis of children with Henoch-Schonlein purpura (HSP) so as to provide a new strategy for treatment of children with Henoch-Schonlein purpura by regulating the balance of Th17 and Treg cells.METHODS: Forty children with Henoch-Schonlein purpura in acute phase admitted in our hospital from February 2012 to March 2013 were enrolled in this study, forty healthy children were simultaneously used as controls. The expression of RORγt mRNA and FoxP3 mRNA in peripheral blood mononuclear cells was detected by real-time PCR using SYBR Green I. The levels of IL-17A, TGF-β1, IL-2 and IL-6 in serum were measured by ABC-ELISA. The ratio of Th17 cells to Treg cells in peripheral blood T lymphocytes was detected by flow cytometry.RESULTS: The levels of Th17 cells (2.75 ± 0.60%) and RORγt mRNA (1.11 ± 0.51) in HSP group were significantly higher than levels of Th17 cells (1.41 ± 0.29%) and RORγt mRNA (0.65 ± 0.24) (P < 0.01) in control group, but the levels of Treg cells (4.56 ± 1.26%) and FoxP3 mRNA (1.15 ± 0.45) in HSP group were lower than those of Treg cells (7.85 ± 1.97%) and FoxP3 mRNA (2.32 ± 1.1) (P < 0.01) in the control group. The relative levels of serum IL-17A, IL-6, TGF-β1 (40.40 ± 11.81 pg/ml, 75.38 ± 27.19 pg/ml, 309.41 ± 81.03 pg/ml) in the HSP group were significantly higher than those in the control group [IL-17A (20.32 ± 10.70 pg/ml), IL-6 (25.16 ± 8.31 pg/ml), TGF-β1 (236.34 ± 66.01 pg/ml)] (P < 0.01), but the level of serum IL-2 (25.60 ± 13.19 pg/ml) in the HSP group was lower than that (34.42 ± 11.69 pg/ml) in the control group (P < 0.01). The further detection demonstrated that in the children with acute HSP, the expression of Th17 cells positively correlated with RORγt mRNA, IL-17A and IL-6 with the correlation coefficients of 0.887, 0.938 and 0.934 (P < 0.01), respectively. The positive correlation was also shown between the Treg cells and FoxP3 mRNA, IL-2 with the correlation coefficients of 0.834 and 0.932 (P < 0.01), respectively.CONCLUSION: There are higher expression levels of Th17 cells, RORγt mRNA and IL-17A, and lower expression levels of Treg cells, FoxP3 mRNA of children with HSP in acute phase, which shows that Th17/Treg imbalance exists in children with HSP in acute phase. The levels of serum IL-6, TGF-β1 increase and the serum IL-2 decrease in children with HSP in acute phase, moreover, there are the positive correlations between the levels of Th17 cells and expression of IL-6, as well as the level of Treg cells and expression of IL-2 in children with HSP in acute phase.

The aim of this study was to determine the relationship between nuclear factor κB and the prognosis of patients with nasopharyngeal carcinoma. We used immunohistochemical studies to examine nuclear factor κB expression in 42 patients with nasopharyngeal carcinoma. The results showed that tumors positive for nuclear factor κB were associated with an increased relapse potential, poor disease-free survival, and reduced overall survival in nasopharyngeal carcinoma. Our study indicates that nuclear factor κB could be an independent molecular marker for predicting poor prognosis among patients with nasopharyngeal carcinoma. Understanding the biology of nuclear factor κB-mediated pathways may lead to the development of novel therapeutic strategies for nasopharyngeal carcinoma. © 2010 Springer Science+Business Media, LLC.

Motor neuron disease (MND) is occasionally aggravated by chronic infection. A misdiagnosed case of tuberculosis with MND is illustrated in a 45-year-old woman who underwent successful VATS wedge excision, which is presented herein. MND in an adult is a rare clinical entity. In order to facilitate the preoperative diagnosis and avoid the misdiagnosis of this disease, more etiological factors need to be considered. © Ren et al.

Background: Primary hepatic carcinoma (PHC) is currently one of the most common worldwide causes of cancer death. Golgi protein 73 (GP73) has been proposed as potential diagnostic marker. However, it is controversial because of inconsistent diagnostic accuracy in different studies. The aim of this study was to assess the diagnostic accuracy of GP73 for PHC. Methods: All the studies relating to the diagnostic accuracy of GP73 for patients with PHC from 1978 to January 2013 were collected. Methodological quality was assessed by Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). The overall diagnostic sensitivity, specificity, and area under the receiver operating characteristic curve were used to evaluate the diagnostic accuracy of GP73 using Meta-DiSc statistical software. Results: Altogether 5,637 subjects were included in the 25 selected studies. The sensitivity and specificity (95% confidence interval) of GP73 was 0.75 (0.73-0.76) and 0.84 (0.83-0.86), respectively. The area under the summary receiver operating characteristic curve (AUC) and Q* index of GP73 was 0.8616 and 0.8021. Conclusions: Serum GP73 has a relatively high diagnostic accuracy in primary hepatic carcinoma with better sensitivity and high specificity than AFP.

The aim of this study was to evaluate the expression of Y-box binding protein-1 (YB-1) in nonneoplastic cervical tissue and cervical cancer tissue and to evaluate its relationship with chemoradiosensitivity in the cases of cervical cancer. We performed immunohistochemical studies to examine YB-1 expression among 59 patients with cervical cancer, 30 with cervical intraepithelial neoplasia (CIN), and 30 with cervicitis. The mean YB-1 histological score(HSCORE)values for cervicitis, cervical CIN, and cervical cancer tissues were 22.3, 39, and 84.4, respectively. The mean YB-1 HSCORE value was 80.0 for cervical cancer patients who showed complete pathological response to chemoradiotherapy and 144.3 for cervical cancer patients who showed partial pathological response. Our data showed that the YB-1 expression was the highest in cervical cancer tissue, followed by cervical CIN tissue, and then cervicitis tissues. High YB-1 expression resulted in a lower pathological response rate in patients of cervical cancer than low YB-1 expression did. Our results implied that YB-1 may play a role in the genesis of cervical cancer and that high YB-1 expression decreases the chemoradiosensitivity of cervical cancers. © Springer Science+Business Media, LLC 2011.

Aim: A recent study shows that YB-1-related biomarkers affect the prognosis of patients with natural killer/T-cell lymphoma (NKTCL). The aim of this study was to determine whether there is an association between YB-1 expression and the prognosis of patients with early-stage extranodal nasal-type NKTCL. Materials & methods: To clarify the roles of YB-1 in early-stage extranodal nasal-type NKTCL, we used immunohistochemical studies to examine YB-1 expression in 36 early-stage extranodal nasal-type NKTCL specimens. Results: Subsequently, YB-1 expression was correlated with clinicopathologic parameters. Higher expression of YB-1 was associated with an increased potential for relapse, poor disease-free survival and reduced overall survival. Discussion: Higher expression of YB-1 could be an independent risk factor for poor prognosis in patients with early-stage extranodal nasal-type NKTCL. Understanding the biology of YB-1-mediated pathways may lead to novel therapeutic strategies for early-stage extranodal nasal-type NKTCL. © 2014 Future Medicine Ltd.

We developed a new method for immobilization of the fix lower extremities by using a thermoplastic mask, a carbon fiber base plate, a customized headrest, and an adjustable angle holder. The lower extremities of 11 patients with lower extremity tumors were immobilized by this method. CT simulation was performed for each patient. For all 11 patients, the device fit was suitable and comfortable and had good reproducibility, which was proven in daily radiotherapy. © 2012 Zheng et al; licensee BioMed Central Ltd.
