Abstract
AIMS To examine single nucleotide polymorphisms in the protein tyrosine phosphatase N22 gene (PTPN22) and to study their association with Type 1 diabetes in a Chinese cohort. METHODS Three hundred and sixty-four young patients with Type 1 diabetes and 719 healthy children were included in this case-controlled study. The genotypes of rs1217385, rs2488457 (-1123C>G), rs1217414, rs1217419, rs3765598 and rs2476601 (1858C>T) in the PTPN22 gene were determined using the SNaPshot method. Alleles, genotypes and haplotype frequencies were compared between patients with Type 1 diabetes and healthy control subjects. The association between single nucleotide polymorphisms and clinical traits/autoantibody status was also analysed. RESULTS The single nucleotide polymorphism, rs1217419, located in the second intron of the PTPN22 gene was associated with Type 1 diabetes (odds ratio 1.5, 95% CI 1.14-1.97, P = 0.003). An additional single nucleotide polymorphism, rs1217385, was also associated with Type 1 diabetes; however, the association was secondary to that of rs1217419. The previously reported single nucleotide polymorphism that is associated with Type 1 diabetes (-1123G>C) had only marginal association with Type 1 diabetes in our study. A marginal association was also identified between -1123G>C and glutamic acid decarboxylase autoantibody positivity in patients with Type 1 diabetes. There was no association between the single nucleotide polymorphism 1858C>T and Type 1 diabetes in our studied cohort. CONCLUSIONS Our study confirmed that PTPN22 is a gene that contributes to Type 1 diabetes susceptibility. The primary association occurs with single nucleotide polymorphism rs1217419 and there is clear heterogeneity of the association between PTPTN22 polymorphisms and Type 1 diabetes in a Chinese population compared with other populations.

Abstract
OBJECTIVES Acrolein (Acr) is a highly reactive α, β-unsaturated aldehyde, which can induce reactive oxygen species (ROS) generation. Several factors, including lipid peroxidation, clinical use of cyclophosphamide, fried foods, automobile exhausts, smoking and aging can increase its concentration in blood serum. Mounting evidence has suggested that Acr-induced ROS might reduce quality of sperm. Thus, the aim of this study was to examine reproductive toxicity of Acr-caused ROS in vitro and find a means to alleviate it. MATERIALS AND METHODS We investigated the effects of Acr on male germ cell (MGC)-derived GC-1 cells in vitro. Dihydroethidium and DCFH-DA fluorescent dyes were used to determine generation of intracellular ROS. RESULTS We found that Acr induced ROS generation, which was accompanied by reduced Bcl2/Bax ratio, substantial decline in mitochondrial membrane potential, and further promoted apoptosis of MGCs. Furthermore, Rapamycin was capable of alleviating Acr-induced ROS, reducing ROS-induced apoptosis by increasing ratio of Bcl2/Bax mRNA and proteins, and protecting MGC mitochondrial membranes. CONCLUSION Rapamycin inhibited Acr-induced apoptosis by alleviating ROS-driven mitochondrial dysfunction in MGCs.

Abstract
The MyoD and Myf6 genes, which are muscle regulatory factors (MRFs), play major roles in muscle growth and development and initiate muscle fibre formation via the regulation of muscle-specific gene translation. Therefore, MyoD and Myf6 are potential candidate genes for meat production traits in animals and poultry. The objective of this study was to evaluate MyoD and Myf6 gene expression patterns in the skeletal muscle during early developmental stage of ducks. Gene expression levels were detected using the quantitative RT-PCR method in the breast muscle (BM) and leg muscle (LM) at embryonic days 13, 17, 21, 25, 27, as well as at 1 week posthatching in Gaoyou and Jinding ducks (Anas platyrhynchos domestica). The MyoD and Myf6 gene profiles in the two duck breeds were consistent during early development, and MyoD gene expression showed a 'wave' trend in BM and an approximate 'anti-√' trend in LM. Myf6 gene expression in BM showed the highest level at embryonic day 21, which subsequently decreased, although remained relatively high, while levels at embryonic days 13, 17 and 21 were higher in LM. The results of correlation analysis showed that MyoD and Myf6 gene expression levels were more strongly correlated in LM than in BM in both duck breeds. These results indicated that different expression patterns of the MyoD and Myf6 genes in BM and LM may be related to muscle development and differentiation, suggesting that MyoD and Myf6 are integral to skeletal muscle development.

Abstract
The species boundaries and evolutionary relationships of two closely related genera, Megalobrama and Parabramis, were inferred from the partial mitochondrial cytochrome oxidase subunit I (COI) gene, NADH dehydrogenase subunit 2 (ND2) gene and their concatenated segment. Phylogenetic reconstructions showed that among the three breams, Megalobrama amblycephala and Megalobrama skolkovii are more closely related to each other than either is to Megalobrama terminalis. The taxonomy of M. pellegrini should be reconsidered. The divergence time estimation based on the assumption of a global molecular clock indicated that speciation and dispersal of the two genera might have occurred at approximately Pliocene to Late Pleistocene, due to major paleo-environmental events associated with monsoon evolution and the formation of the Three Gorges of the Yangtze River.

Abstract
Absolute testing methods are commonly employed in surface metrology to calibrate the reference surface deviation and obtain the absolute deviation of the surface under test. A simple and reliable data-reduction method of absolute shift-rotation method with rotational and translational measurements is presented here, which relies on the decomposition of the surface deviation into rotationally asymmetric and symmetric components. The rotationally asymmetric surface deviation can be simply obtained by classical N-position averaging method. After that, the two-dimensional problem of estimating the other rotationally symmetric surface deviation can be simplified to a one-dimensional problem, and it can be directly calculated out with pixel-level spatial frequency based on several measurements of different translations in one same direction. Since that no orthogonal polynomials fitting, such as Zernike polynomials, is required in the calculation, the data reduction of the method is simple and rapid. Experimental absolute results of spherical surfaces are given.

Abstract
Substantial epidemiological evidence shows an increased risk for developing Alzheimer's disease (AD) in people with diabetes. Yet the underlying molecular mechanisms still remain to be elucidated. This article reviews the current studies on common pathological processes of Alzheimer's disease and diabetes with particular focus on potential mechanisms through which diabetes affects the initiation and progression of Alzheimer's disease. Impairment of insulin signaling, inflammation, oxidative stress, mitochondrial dysfunction, advanced glycation end products, APOEε4 and cholesterol appear to be important mediators and are likely to act synergistically in promoting AD pathology.

Abstract
Recent studies indicate that adiponectin can attenuate cerebral ischemic lesions via its functional area located in the C-terminal globular domain, which is called globular adiponectin (gAD). However, the mechanisms underlying this action remain unclear. In this study, we investigated the antioxidant properties of gAD during cerebral ischemia. Adult male C57BL/6 mice received an intracerebral injection of gAD with or without tetrabromocinnamic acid (TBCA, a NADPH oxidase activator). Mice were subjected to middle cerebral artery occlusion (MCAO) after gAD injection. Infarct volume, neurological function, the activity of antioxidant enzymes (superoxide dismutase [SOD], catalase), the content of malondialdehyde (MDA), and the expression of Bax, Bcl-2, cleaved caspase-3 and NADPH oxidase 2 (NOX2) were examined at 24h after MCAO. Infarct volume was attenuated in gAD-transduced mice when compared with mice in the MCAO group, with significant improvement in neurological function. In addition, neuronal apoptosis was attenuated, along with the expression of Bax/Bcl-2 and cleaved caspase 3. Furthermore, the activities of SOD and catalase increased, and the content of MDA reduced. However, TBCA blocked the effect of gAD on cerebral protection and its antioxidant abilities. Taken together, these results demonstrate that the neuroprotective action of gAD may result from the promotion of antioxidant capacity by inhibiting the NOX2 signaling system.

Abstract
OBJECTIVE To explore the significance of neonatal body indices in identifying macrosomic infants, we compared the neonatal birth weight, body length, head circumference, chest circumference, neonatal body indices, Quetelet index (QI), Kaup Index (KI), head circumference to chest circumference ratio (HC/CC) and maternal fasting blood glucose (BG) for both diabetic and healthy mothers. STUDY DESIGN This is a retrospective study of 177 macrosomic neonates, 100 having been born to normal mothers and 77 to diabetic mothers. Multiple regression analyses were done between neonatal body indices and maternal fasting BG. RESULT Fetal QI and KI indices of macrosomic infants of diabetic mothers were higher compared with those born to healthy mothers, whereas the HC/CC was the reverse. The multiple regression equation used to compare neonatal physical development indices to maternal fasting BG was BG=6.959+0.031QI-(4.482 × HC/CC). QI and HC/CC had linear relationships to maternal fasting BG (P<0.05). As birth weight had no direct correlation with maternal fasting BG, it was not introduced into the regression equation. CONCLUSION Higher QI and KI along with lower HC/CC may be a predictor of macrosomia due to maternal diabetes when compared with birth weight alone.
