Polysaccharides widely exist in animals, plants, microorganisms, and possess various biological activities including anti-tumor, anti-virus, anti-oxidant and immunomodulatory. Polysaccharides shows notable anti-tumor activity and less toxicity, and becomes a hotspot in the studies of anti-tumor drugs. Therefore, there is huge potential for developing polysaccharides into a novel antitumor medicine. This article summarized polysaccharides derived from animals, plants, microorganisms which have significant antitumor effect in the latest 5 years; findings indicate that polysaccharides show the anti-tumor effect directly by inducing tumor cell apoptosis and indirectly as an immunoenhancement. This article also looks into the future of studies on anti-tumor activity of polysaccharides.

AlM: To measure ocular biometric values with the degree of axial myopia and determine the relationship between the differences using the Lenstar 900.
METHODS:Totally 413 myopes (826 eyes) were enrolled in this study and were divided into 3 groups: low myopia (myopia <3. 00 diopters, 104 eyes), moderate myopia ( myopia =3. 00-6. 00 diopters, 500 eyes) and high myopia ( myopia > 6. 00 diopters, 222 eyes ). Central corneal thickness ( CCT ) , aqueous depth ( AD ) , lens thickness (LT), axial length (AL) were measured by Lenstar 900. The parameters were tested using analysis of variance and the relations among SE, AL, LT were analyzed.
RESULTS: There were significant difference both in AL (F=206.16, P<0.01) and AD (F=4.764, P<0.05) and no significant difference both in CCT and LT between these myopia groups. With analysis of Person, the Spherical equivalent ( SE) shows a significantly positive correlation with AL (r=0. 662, P<0. 01) and AD (r=0. 095, P<0. 05), no correlation with CCT and LT. AL shows a significantly positive correlation with AD (r=0. 347, P<0. 01) and CCT (r=0.126, P<0.01), negative correlation with LT (r=-0.265, P<0. 01). LT shows a significantly negative correlation with AD (r=-0. 496, P<0. 01).
CONCLUSlON: Along with the diopters increasing in myopia, the axial length and aqueous depth continue to increase. Spherical equivalent ( SE) shows a significantly positive correlation with AD. AL shows positive correlation with SE, AD and CCT and negative correlation with LT. LT shows a significantly negative correlation with AD.

Two Pseudomonas strains, K80 - B and K80 - A, can use hydrocarbon as carbon source by two different mechanisms. Different effects can be observed when they are applied to 69-8 oil of Dagan Oil Field. The strain K80-B producing both hydrocarbon pseudosolubilizing factor and hydrocarbon emulsifying factor can decrease the viscosity and solidifying point of the 69-8 oil 51.6% and 2℃ respectively. Whereas the other can only decrease 43.5% and 3℃ respectively. When the two strains are mixed, synergistic effect on crude oil is obvious.

A poly-?-glutamic acid producing strain--BLN-2, was isolated from the soybean products. According to the biochemical characteristics and 16S rRNA, the strain was identified as Bacillus subtilis. Using soybeans as culture, the solid-state fermentation conditions of BLN-2 have been studied. The results showed that the optimal carbon and nitrogen sources of BLN-2 were glucose, fructose, NaNO3 and KNO3, respectively. The orthrogonal experiments showed, when the final concentration of the fructose which was added to the soybean culture was 0.5%, the glucose, NaNO3 and KNO3 final concentraion were 2.0%, the production of ?-PGA was the highest--89.05 g/kg. It is 48.42% higher than other comparable soybean medium under the same conditions.
