Endostatin(ES), the C-terminal fragment of collagen XVIII, is a potent angiogenesis inhibitor. At present, there are a large number of research papers on ES. It has already been on clinical stage Ⅱ and been widely used in inhibition of neovascularization(NV). However, how to improve the bioactivity of ES is still a matter of ongoing discussion. The objective of this review is to elucidate the relationship between the modified ES and ocular neovascualrization, and to discuss the superiority based on the structure modification. The structure can be changed either by covalent modification or by genetical mutation. It is proposed that the secondary structral ES enhance the anti-angiogenic activity. Studies on modified ES also shed light on our understanding of the molecular action mechanisms of ES. Modified ES may be exploited as a new angiogenesis inhibitor for therapeutic applica-tions, in substitution of the native ES. Activity

Objective To investigate the expression and localization of dopamine- and cAMP-regulated phosphoprotein of 32 000 (DARPP-32) in mouse kidney tissue. Methods The cellular localization of DARPP-32 in mouse kidney tissue was detected by immunoblot and immunohistochemistry. Results DARPP-32-like immunoreactivity was detected in the medullary thick ascending limb of the loop of Henle, the cortical proximal convoluted tubule, and collecting ducts in medullary rays. The renal tubules were enriched of Na+, K+-ATPase for sodium reabsorption. Conclusion The participation of DARPP-32 is a likely crucial step of the signal-transduction pathway of dopamine regulation on sodium reabsorption in renal tubule cells.

Several specific monoclonal antibodies for B, T and natural killer (NK) cell were used to investigate the B cell localization and the expression of their phe- notype in lymphoid nodules on frozen and paraffin sections of human tonsil and lymph node by means of an immunocytochemical ABC technic. The results indi- cate that monoclonal antibodies reactive with germinal centers in tonsil and ly- mph node gave a simlar results and the results indicate that transformation and germination of germinal center cells involve phenotype changs but except T-200. For example, in the lower zone of germinal center, the lymphoblasts are weakly stained for IgM andLN-2 antibodies, but not for OKB-2 and BA-1, while in th upper zone the centrocytes are intense staining for IgM, LN-2, OKB-2 and BA-1 antibodies arelight or moderate staining separately Further charaterization of B cells in upperzone is frenquently observed clcavages on their nuclear memb- rane. In the mantle zone, the lymphocytes are strongly reacted with OKB-2 and BA-1, middle staining for LN-2 and light staining for sIgM. Plasma cell is only reactive with T-200 and IgM antibodies.

Research on the association between maternal periodontal disease and the risk of preeclampsia has generated inconsistent results. This meta-analysis was conducted to evaluate the association between maternal periodontal disease and the risk of preeclampsia. A literature search of PubMed and Embase was performed to identify relevant papers published before March 2013. Only observational studies that assessed maternal periodontal disease and the risk of preeclampsia were selected. Patients' periodontal status was examined at different time points during pregnancy or after delivery (at 14-32 weeks of gestation, within 48 h prior to or within 5 days after delivery). Pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated for cases and controls. Cases were defined as women with concurrent hypertension and proteinuria after 20 weeks of gestation. Eleven studies involving 1118 women with preeclampsia and 2798 women without preeclampsia were identified and analyzed. Women with periodontal disease before 32 weeks of gestation had a 3.69-fold higher risk of developing preeclampsia than their counterparts without periodontal disease (OR=3.69; 95% CI=2.58-5.27). Periodontal disease within 48 h prior to delivery was associated with a 2.68-fold higher risk of preeclampsia (OR=2.68; 95% CI=1.39-5.18). Pregnant women with periodontal disease within 5 days after delivery had a 2.22-fold higher risk of preeclampsia than women without periodontal disease (OR=2.22; 95% CI=1.16-4.27). In conclusion, this meta-analysis suggests that maternal periodontal disease is an independent predictor of preeclampsia.

Objective To investigate the influence of murine cytomegalovirus(MCMV) infection on differentiation and differentiation gene expression of neural stem cells (NSCs) in vitro for studying the mechanisms of brain abnormalities calmed by congenital cytomegalovirns infection. Methods NSCs were separated from fetal BALB/c mouse and cultured and identified in vitro. The differentiation potency of NSCs was observed by immunnfluorescence. The NSCs infected by MCMV at dosage of multiplicity of infection (MOI) equaled to 5, I and 0. 1, respectively, were cultured in differentiation medium. The morphological changes of the cells were observed by inverted microscope. The ratios of NSCs and its differentiated cells were detected by flow cytometry. The expression changes of nestin, GFAP and NSE, markers of NSCs and its differentiated cells, were studied by immunofluorescence ( MOI = 1 ). The expression of early antigen (EA) of MCMV was detected to observe the infection process. Real-time RT-PCR method was employed to measure the expression levels of the key differentiation genes Wnt-3 and Wnt-7a in Wnt signal pathway of NSCs at early phage of differentiation culture. Results NSCs isolated from embryonic mouse brains could proliferate to form neurnspheres and strongly express Nestin and differentiate into NF-200 positive neurons or GFAP positive astrocytes. The NSCs of the infected groups couldn't adhere to the wall and appear differentia-tion growth, but showed swollen gradually after differentiation culture. The nostin expression of the infected groups downregulated slowly and was higher than that of the control groups ( P < 0.05 ). The GFAP and NSE expression of the infected groups were lower than that of the control groups (P <0.05). The EA of MCMV could be always detected in the cells of the infected groups. The ratios of nestin positive cells of the infected groups were higher than that of the control groups, but the ratios of GFAP and NSE positive cells of the for-mer were lower than that of the latter from 3rd to 9th day after differentiation culture ( P < 0.05 ). The levels of Wnt-3 mRNA and Wnt-7a mRNA of the infected groups were markedly lower than that of the control groups from 1st to 2nd clay and from 12th hour to 2nd day after differentiation culture respectively ( P < 0.05 ) . These changes of the infected groups became more obvious as MCMV MOI increased . Conclusion MCMV could inhibit significantly NSCs differentiate to neurons and astrocytes and lead to the decrease of dif-ferentiated cells. MCMV could inhibit or interfere with the gene expression of Wnt-3 and Wnt-7a in Wnt sig-nal pathway of NSCs. The effect that MCMV inhibited the differentiation and the differentiation gene expres-sion of NSCs showed dose-dependent with MCMV MOI. The inhibitory effect of MCMV on the differentiation of NSCs might be induced by interfering the differentiation gene expression of NSCs, which is possibly the one of primary causes of brain development disorders caused by congenital CMV infection.
