The atherogensis was involved in a complex pathological process. Injury to endothelial cells of blood vessels was confirmed to be the in itial stage of this process. Migration to subendothelial layer and accumulation and proliferation of smooth muscle cells were attributed to various cytokines an d adhesive molecules secreted by activated endothelial cells, subsequently resul ting in aggregation of lymphocytes,platelets, monocytes and macrophages in the i ntima of artery. These cellular components ultimatedly led to the formation of a mature atherosclerotic plaque. Its quite acknowledged that a better understan ding of the atherogenic events might promise us the development of new chemical entities of anti-atherosclerotic therapies. A large body of evidence has demons trated that sulfated polysaccharides played a critical role in the development o f atherosclerosis. The underlying mechanisms of the anti-atherosclerotic activi ty of sulfated polysaccharides were reported to contribute to protecting against endothelial cells injury,inhibiting migration and proliferation of vascular smo oth muscle cells, and reducing the adhesion of inflammatory cells, platelets and lymphocytes. And also, the prevention of complement activation by sulfated poly saccharides could not be excluded. On the other hand,the promoting effects of su lfated polysaccharides atherosclerosis was also reported. Its therefore conclu ded that the relationships between atheriosclerosis and sulfated polysaccharides remained to be further elucidated.

Two aberrant structures, extracellular senile plaques (SP) and intracellular neurofibrillary tangles (NFTs) are the characteristic neuropathological hallmarks of Alzheimers disease (AD). Amyloid ? protein (A?) and hyperphosphorylated tau protein are the major components of SP and NFTs respectively. A large body of evidence has highlighted the pivotal role of sulfated polysaccharides in the amyloidogenesis and formation of NFTs. The underlying mechanisms of the involvement of sulfated polysaccharides in the development of AD were reported to contribute to their high affinity for both A? and tau protein. Sulfated polysaccharides not only promoted the ? secretase cleavage of APP and the increased production of A? and induced the aggregation and deposition of A?, but also facilitated the phosphylation of tau and promoted tau polymerization into fibrils and tangle formation. On the other hand, the neurotrophic effects exerted by sulfated polysaccharides were also demonstrated. These notions were probably due to the inhibition of the formation of A? fibrils or to the counteraction of the abnormal phosphorylation of tau by promoting the protein phosphatase2B activity, which has been speculated to be attributed to the variation in either structural backbone or degree of sulfation or position of sulfation. Putting together, the appropriate structural modification of sulfated polysaccharides may be effective as therapeutic agents for AD.

The protective effect of 916 on lymphocyte damage induced by H 2O 2 was studied in this paper. Exposure of 916 at given concentrations to lymphocyte was concomitantly incubated with H 2O 2 at concentration of 12.5?mol?L -1 . Two hours later, the viable cells were evaluated by MTT assays. The result indicated that 916 exerted significant protective effect on lymphocyte from injury, indicating a potent antioxidant activity.

Objective To explore the measurement of(1,3)-β-D glucan in plasma for the diagnosis of pulmonary fungal infections in pulmonary tuberculosis patients. Methods 40 pulmonary tuberculosis patients with pulmonary fungal infections in Guangzhou chest hospital from January 2015 to December 2015 were enrolled as a test group,among which 35 were confirmed and 5 were suspected pulmonary fungal infections. 52 pulmonary tuber-culosis patients without fungal infections were selected as a control group.(1,3)-β-D glucan content(G test)in this 92 patients plasma were detected. The results of G tests were compared with those from etiological diagnosis to assess the performance of G test. Results 13 strains of candida albicans,13 strains of aspergillus,2 strains of candida tropicalis,2 strains of candida glabrata and 6 strains of other yeast were obtained from patients of test group,but no fungal identified from those of control group. The median of G test in test group and in control group was 126.1 and 29.56 pg/mL,respectively,the level in test group was significantly higher than that in control group (P<0.001). 35 cases were identified as positive and 5 were negative in test group by G test ,while 41 cases were identified as negative and 11 were positive in control group. The sensitivity,specificity,positive predictive value, negative predictive value ,concordance and Youden index of G test were 87.5%,78.85%,76.09%,89.13%, 82.6%and 0.663,respectively. Conclusions Candida albicans and aspergillus are more common pathogens than the other fungi isolated from pulmonary tuberculosis patients with pulmonary fungal infection. G test ,used in pul-monary tuberculosis with pulmonary fungal infections diagnosis,is reliable and fast,and has a higher sensitivity, specificity and accuracy.

Objective To study the exocrine pancreatic function in critically ill children with septic shock,sepsis and hyperlactacidemia.Methods A total of 64 critical pediatric patients were admitted from Jan 2009 to Oct 2012,and clinical and laboratory findings including pancreatic function,and histopathological features and score after autopsy were reviewed.Results (1) Compared with non-septic shock children,the pancreatic pathology score and serum lipase in septic shock group were significantly higher and serum calcium was significantly reduced (P ＜0.05) ; (2) The pancreatic histopathology score was significantly increased in patients with elevated plasma lactate ≥2 times (P ＜0.05),but there were no significant differences in serum calcium and blood amylase and lipase between patients with elevated plasma lactate level and patients with normal plasma lactate level; (3) The concentrations of serum amylase,lipase and urinary amylase were significantly increased in patients with pancreatic histopathology score ＞4 points compared with score ≤4 points patients,but there were no significant differences in above three biomarkers between patients with score ≤3 points and patients with score ＞3 points.Conclusions The pancreas is vulnerable to damage easily occurred in septic shock children especially complicated with hyperlactacidemia.The pancreatic histopathology score ＞ 4 points can be as a sensitive and reliable indicator of pancreas damage.

Objective To explore the feasibility of visually assessment of angiogenesis in a murine model of subcutaneous matrigel plugs with ultrasound molecular imaging(UMI) using microbubbles(MB)targeted to endothelial αv-integrins. Methods Matrigel angiogenesis was created by subcutaneous implantation of FGF-2 enriched matrigel in 10 mice. On day 10, UMI of the matrigel was performed in all mice at 6 minutes after intravenous injection of either αv-integrin targeting microbubbles(MBα) or isotype control microbubbles(MBc) in random with 30 min interval,and the video intensity(Ⅵ) was measured. To further test the specificity of the signal coming from MBα,antibody against αv-integrin was injected 10 min before microbubbles injection. Following UMI,all matrigels were harvested for histological analysis. Results As expected,VI of the matrigel was significantly higher ( P ＜0.05) for MBα (20. 5 ± 3.3)U as compared with MBc (4. 8 ± 1.5)U. After blocking with antibody against αv-integrin,a great decrease was observed in the MBα group [VI (4.6 ± 1.2) U, P ＜0.05] while no significant difference was noted for MBc [VI (4. 9 ±1.5)U, P ＞ 0.05 ]. Neovessels within matrigel was positive for αv-integrin. Conclusions UMI with microbubbles targeted to αv-integrins can be effective and specific in evaluating the angiogenesis in a murine model of subcutaneous matrigel plugs.
