AlM: To investigate expressions of matrix metalloproteinase-2 ( MMP-2 ) and extracellular matrix metalloproteinase inducer ( EMMPRlN) in retinoblastoma (Rb) and the relationships between MMP-2, EMMPRlN and tumor development.METHODS:lmmunohistochemical technique was used to detect expressions of MMP-2 and EMMPRlN in 39 cases of paraffin embedded Rb samples. Quantitative analysis of expressions of MMP-2 and EMMPRlN were assessed by measuring the mean gray scale of Rb tissue with LElCA lM50 Color Pathologic Analysis System. The differences of expressions of MMP-2 and EMMPRlN in each clinical and pathological stage were statistically analyzed, and the same step was also undertaken to study the relationship between Rb with MMP-2 positive expression and that with EMMPRlN positive expression.RESULTS:The positive expression rate of MMP-2 was 90% (Gray value: 109. 64 ± 14. 52; 35/39), and that of EMMPRlN was 85% (Gray value:108. 01±13. 60;33/39). The expressions of MMP - 2 and EMMPRlN were significantly higher in tumors of glaucomatous stage (Gray value:108. 21±11. 47 and 107. 56±14. 32) than those in intraocular stage ( Gray value: 121. 13 ± 11. 32 and 119. 34 ± 12. 66; P<0. 01 and P<0. 05). And the same conclusion can be concluded between those in extraocular stage (Gray value: 91. 03 ± 11. 71 and 92. 26 ± 12. 93) with those in glaucomatous stage (P<0. 01 and P<0. 05). The expressions of MMP-2 and EMMPRlN were significantly higher in tumors with optic nerve invasion (Gray value:103. 89±13. 39 and 105. 23±14. 00) than those without optic nerve invasion ( Gray value: 118. 39 ± 15. 11 and 117. 53±16. 13) (P<0. 01 and P<0. 05).CONCLUSlON:The positive expression levels of MMP-2 and EMMPRlN may correlate with tumor infiltration and metastasis.

The retinal image registration has important applications in the processes of auxiliary diagnosis and treatment for a variety of diseases. The retinal image registration can be used to measure the disease process and the therapeutic effect. A variety of retinal image registration techniques have been studied extensively in recent years. However, there are still many problems existing and there are numerous research possibilities.

Macrophages are involved in many important biological processes and membrane proteins are the key effector molecules for their functions. However, membrane proteins are difficult to analyze by 2-DE based method because of their intrinsic tendency to self-aggregate during the first dimension separation (IEF). To circumvent the obstacle hampering membrane protein analysis, we combined one-dimensional SDS-PAGE with capillary liquid chromatography-tandem mass spectrometry (LC-MS/MS). Using this technique, we identified 458 GO annotated membrane proteins with extremely high confidence, including most known markers of peritoneal macrophages (e.g., CD11b, F4/80, CD14, CD18, CD86, CD44, CD16 and Toll-like receptor). Thirteen other CD antigens and 18 Ras-related small GTPase were also identified. In addition to those known macrophage membrane proteins, a significant number of novel proteins have also been identified. This research provides a valuable data set of macrophage membrane proteins, thus allowing for more comprehensive study of membrane proteins and a better understanding of the function mechanisms of macrophages in many biological processes.

Objective To observe the activities of serum peroxidase capacity,and lipid peroxidation of children from Kaschin-Beck disease (KBD) areas of Xinghai county in Qinhai province,and to explore the relationship between antioxidant capacity and KBD.Methods Sixty four KBD and forty six health subjects without KBD were chosen from KBD endemic areas,which included primary schools of Tangnaihai,Xialujuan and Qushian of Xinghai county in Qinghai province,and fifty nine age-matched healthy control subjects without KBD were from a non-KBD endemic area,Nanfan primary school of Chang'an county in Shaanxi province.Twenty patients with KBD and twenty control subjects from KBD areas and non-KBD area were extracted by simple random sampling method.2,3-DAN fluorescence technique was used to test the hair and blood selenium.The biochemical techniques were used to test the indicators of oxidative stress including malondialdehyde(MDA),antioxidant enzyme activities,total antioxidant capacity(T-AOC),serum superoxide dismutase(SOD),catalase(CAT) and glutathione peroxidase(GSHPx).ResultsAll patients with KBD had significantly lower serum GSH-Px activities[ (59.53 ± 25.23)kU/L] and selenium levels in hair[ (67.64 ± 17.28)μg/L] and blood[(36.27 ± 13.29)μg/L],respectively,than that of control subjects from KBD areas [ ( 91.88 ± 22.99 ) kU/L,( 153.32 ± 24.31 ) μg/L,( 63.06 ± 13.66) μg/L ] and nonKBD areas[ ( 122.68 ± 41.74)kU/L,(242.35 ± 38.56)μg/L,(98.93 ± 17.18)μg/L,all P ＜ 0.05].Serum MDA levels in KBD patients[ (4.64 ± 1.11 )μmol/L] were significantly higher than that in control subjects from KBD [(3.31 ± 1.22)μmol/L] and non-KBD areas[ (3.43 ± 1.29)μmol/L,all P ＜ 0.05].On the other hand,T-AOC,SOD and CAT activities were significantly higher in both KBD[(19.80 ± 6.64),(55.80 ± 8.14),(16.45 ± 5.61 ) kU/L] and control subjects[ (21.71 ± 8.82),(57.45 ± 6.96),(15.63 ± 9.18)kU/L] from KBD areas than that of control subjects from non-KBD area[ (13.56 ± 5.38),(42.79 ± 8.10),(6.05 ± 2.71 )kU/L,all P ＜ 0.05 ].Hair selenium levels,blood selenium levels and GSH-Px activity of control subjects from KBD areas were,respectively,significantly lower than that in control subjects from non-KBD area(all P ＜ 0.05).Conclusions These findings strongly confirm the evidence that KBD patients are susceptible to oxidative stress.The results also show the increase in antioxidant enzymes,which could probably be due to adaptive response to pro-oxidant in KBD state.Hence,there seems to be an imbalance between oxidant and antioxidant systems in KBD patients.

Objective: Rumination is a maladaptive emotional-regulation strategy that is strongly associated with depression. Impaired executive function can lead to difficulties in disengaging from rumination, thus exacerbating depression. In this study, we inspect an electroencephalograph neurofeedback protocol that enhance the target peak alpha frequency (PAF) activation in the prefrontal region. We examine the protocol’s effects on depression and rumination. Methods: We randomly assigned 30 dysphoric participants into either the neurofeedback training group or the control group. We then evaluated their depression, rumination, and executive function at pre- and posttraining so as to examine the effects of the neurofeedback. Results: The results show that this neurofeedback protocol can specifically enhance participants’ target PAF. The participants’ executive function performances significantly improved after undergoing 20 neurofeedback sessions. Compared with those in the control group, those in the neurofeedback group had significantly fewer depressive symptoms and significantly reduced rumination. Moreover, as target PAF and executive function improved, depression and rumination both declined. Conclusion Our data are in line with those of previous studies that indicated a relationship between upper-band alpha activity and executive function. This PAF neurofeedback can effectively enhance participants’ executive function, which can reduce rumination and ameliorate depression. This neurofeedback training is based on basic cognitive neuroscience, so it sheds light on depression’s pathological factors and etiology.

The effects of the feed attractants on Whitmania pigra were studied. The average weight of Wh. pigra were 5.0 g. Arginine was selected as feed attractants, xanthan gum was selected as feed substrate. The times of Wh. pigra going into the inducing room were recorded. The water temperature was 22-25 degrees C during the whole experiment. Arginine that had better inducing effect was chosen to carry on in the gradient experiment. The results showed that the best inducing effect was found when the added amount of arginine was 0.3%, which was close to the arginine content of the natural body fluid of Wh. Pigra and Bellamya purificata, 2.97 mg x g(-1).
