Abstract
This study was designed to evaluate the effects of semen processing on the generation of intracellular reactive oxygen species (ROS) and mitochondrial membrane potential (MMP) in spermatozoa, and to develop reliable indexes for the evaluation of sperm quality during sperm preparation. Swim-up and density gradient centrifugation methods were used to separate semen in oligoasthenoteratozoospermia (OAT), leucocytospermia (LC) and normozoospermia groups. Levels of ROS and MMP were measured by flow cytometry. Before preparation, the patients with abnormal semen parameters had a lower MMP and higher ROS, and there was a negative correlation between MMP and ROS. The levels of MMP and ROS increased significantly, especially ROS produced by swim-up. A significant difference was found between the correlation of MMP and total normal motile sperm count after preparation in the OAT group. The level of ROS was associated with the amount of white blood cells in the LC group. The MMP can be used as an objective index to evaluate the sperm quality of OAT patients, and the combination of MMP and ROS can be used to assess the efficiency of sperm preparation in LC patients. These findings can guide selection of the ideal sperm separation technique for different sperm samples.

Abstract
The aim of this study was to investigate the effects of overtraining on skeletal muscle growth and growth-related gene expression. The rats of overtraining group (OT) and overtraining recovery group (OTR) were subject to 11 experimental weeks of overtraining protocol. It was found that the absolute gastrocnemius muscle wet weight of the OT group was significantly lower than that of the sedentary group (23.6%, P<0.01). Serum creatine kinase was significantly higher in the OT and OTR groups than the sedentary group. CD68, CD163, MyoD, myogenin, IL-1β, TNF-α, IGF-I and MGF mRNA did not change in the OT group as compared with the sedentary group. IL-6 and TGF-β1 mRNA in the OT group increased significantly as compared with the sedentary group (2.17 fold and 1.78 fold, respectively; P<0.01). IL-10 mRNA decreased significantly in the OT group (63%, P<0.01) and the OTR group (77%, P<0.01) compared to the sedentary group. COX-2 mRNA decreased significantly in the OT group (60%, P<0.01) and the OTR group (69%, P<0.01) from the sedentary group. uPA mRNA in the OT group was significantly lower than that in the sedentary group (32%, P<0.01). These data suggest that inflammatory cytokines, COX-2 and uPA may play roles in the inhibition of skeletal muscle growth induced by overtraining.

Abstract
The aim of this study was to examine the expression of the molecular markers cyclooxygenase-2 (COX-2), Ki-67, cyclin A, and p27 in patients with esophageal squamous cell carcinoma (ESCC), to ascertain the relationship of these makers with the clinicopathological significance of the patients, and to assess the additional prognostic value of the expression profile of these proteins for ESCC patients. The expression levels of COX-2, Ki-67, cyclin A, and p27 proteins of a series of primarily resected ESCC samples were determined by immunohistochemistry method. Clinicopathological and molecular factors affecting survival were analyzed by multivariate analysis. A total of 78 specimens were included in this study. Expression of COX-2 was observed in 43 (55.1%) cases, and high levels of expression of Ki-67, p27, and cyclin A were observed in 57 (73.0%), 33 (42.3%), 43 (55.1%) cases, respectively. The results of univariate survival analysis indicated that more advanced tumor stage, lymph node involvement, systemic dissemination, the levels of expression of COX-2, Ki-67, cyclin A, and p27 were associated with survival (all P-value < 0.05). Multifactorial survival analysis revealed that only lymph node involvement, over-expression of cyclin A, and low p27 expression were associated with the survival of the patients (hazard ratios = 2.83, 4.7, 2.9, respectively; P= 0.025, 0.042, 0.005, respectively). Among the molecular markers assessed, the expression of cell proliferation markers cyclin A and p27 are independent prognostic factors in patients with ESCC, whereas neither COX-2 nor Ki-67 is of independent prognostic value.

Abstract
A large number of natural killer (NK) cells with high function are expected to generate especially in tumor adoptive immunotherapy. Here K562 cells were genetically modified to co-express major histocompatibility complex class I chain-related protein A (MICA), 4-1BB ligand, and IL-15, called K562-MICA-4-1BBL-IL-15. The modified K562 cells not only promoted activation, proliferation, and survival of NK cells, but also enhanced NK cell cytotoxicity. In long-term culture tests, K562-MICA-4-1BBL-IL-15 cells stimulated NK cell to expand mean 550 folds in 24-day culture and to cover from 14.8% of total peripheral blood monoclonal lymphocytes on day 1 to 86.7% on day 24. Prevalent NK cells after expansion enhanced the ability of killing targets and producing interferon gamma (IFN-γ), and kept high expression of activating receptors. The results indicated that K562-MICA-4-1BBL-IL-15 cells would be developed for expansion of NK cells ex vivo and may have important implications for clinical immunotherapy.

Abstract
OBJECTIVE To analyse the concentration of interleukin (IL)-17 and IL-23 in serum and ex vivo culture supernatant of peripheral blood mononuclear cells (PBMCs) from patients with polymyositis (PM) and dermatomyositis (DM) compared with healthy controls (HC). METHODS Enzyme-linked immunosorbent assay (ELISA) was used to analyse the concentration of IL-17 and IL-23 from 25 patients with PM, 21 patients with DM, and 12 HC in serum or ex vivo culture supernatant of PBMCs following stimulation ex vivo with anti-CD3/CD28 for 72 h. RESULTS The levels of IL-23 increased in the serum and culture supernatant of patients with PM and patients with DM compared with HC. By contrast, concentrations of IL-17 in supernatants from patients with PM and DM were not significantly higher than those from HC. We subdivided the group of DM and PM patients into those with early disease versus those with established disease and found that the levels of IL-17 and IL-23 were much higher in early stage compared to established disease. CONCLUSION We have demonstrated that stimulated PBMCs from DM and PM patients produce increased levels of IL-23 as compared to HC. IL-17 and IL-23 levels are increased in early as compared to established disease. This provides further evidence that IL-17/IL-23 may play a crucial role in autoimmune diseases.

Abstract
Using ab initio density functional theory calculations, we have investigated the influence of Mo, V and Pd on the H-induced grain boundary embrittlement in Fe. We find that, in the high impurity concentration systems, all of the three alloying elements facilitate H embrittlement at the Σ3 (111) [Formula: see text] grain boundary in Fe. The calculated binary effects of the H-X (X = Mo, V, Pd) couples are 0.063, 0.074 and 0.040 eV, respectively. On the other hand, in the large unit cell with low impurity concentration, both Mo and V can facilitate H embrittlement, and the binary effects of pairs are 0.152 and 0.164 eV, respectively. While Pd reduces the H embrittlement on the cohesion of the Fe grain boundary with the binary effect of - 0.1 eV. The H-X (X = Mo, V, Pd) interactions are interpreted by electronic structure analyses.

Abstract
Background: The aim of this study is to seek an association between markers of metastatic potential, drug resistance-related protein and monocarboxylate transporters in prostate cancer (CaP). Methods: We evaluated the expression of invasive markers (CD147, CD44v3-10), drug-resistance protein (MDR1) and monocarboxylate transporters (MCT1 and MCT4) in CaP metastatic cell lines and CaP tissue microarrays (n=140) by immunostaining. The co-expression of CD147 and CD44v3-10 with that of MDR1, MCT1 and MCT4 in CaP cell lines was evaluated using confocal microscopy. The relationship between the expression of CD147 and CD44v3-10 and the sensitivity (IC50) to docetaxel in CaP cell lines was assessed using MTT assay. The relationship between expression of CD44v3-10, MDR1 and MCT4 and various clinicopathological CaP progression parameters was examined. Results: CD147 and CD44v3-10 were co-expressed with MDR1, MCT1 and MCT4 in primary and metastatic CaP cells. Both CD147 and CD44v3-10 expression levels were inversely related to docetaxel sensitivity (IC50) in metastatic CaP cell lines. Overexpression of CD44v3-10, MDR1 and MCT4 was found in most primary CaP tissues, and was significantly associated with CaP progression. Conclusions: Our results suggest that the overexpression of CD147, CD44v3-10, MDR1 and MCT4 is associated with CaP progression. Expression of both CD147 and CD44v3-10 is correlated with drug resistance during CaP metastasis and could be a useful potential therapeutic target in advanced disease.
