Heparinases,a kind of polysaccharide lyases,can degrade heparin and heparin sulfate to low molecular weight polysaccharides.It has been noted that many bacteria have heparinases although only few of them have been purified and characterized.Heparinases I,II and III from Flavobacterium heparinum have been extensively studied for many years and been commercialized recently.Heparinases have some important applications in the industry and clinic as well as in the determination of heparin structure,which is a very important anticoagulant drug used world-widely.The recent progresses in isolation of heparinase-producing bacteria,genome mapping of heparinase homologs in sequenced bacteria and archaea genomes,purification of heparinases and the study of their biochemistry and regulation were reviewed.The recombinant expression of these enzymes as well as important applications of heparinases and their potential applications in the future will also be highlighted.

Objective To explore the relationship between methylenetetra hydrofolate reduetase (MTHFR) C677T genotypo and unstable angina pectoris(UA) in Chinese population. Methods The study consisted of 90 UA cases (UA group), and an age- and sex- matched healthy control cases (control group, n = 90). PC R-RFLP was used to analyze polymorphism of the MTHFR C677T genotypo. The relationship between MTHFR C677T genotype and UA was observed. Results MTHFR 677C→T mutation was found in 30 of 90 patients with unstable angina pectoris (33.33%) and in 15 of 90 control subjects (16.67%). This difference was statistically significant (P<0.05). Conclusion MTHFR 677C→T mutation is closely related to the unstable angina poctoris.

Cancer, also known as malignant tumor, is the second largest disease after heart disease, which is characterized by genomic instability and mutagenicity. Ataxia telangiectasia and RAD3-related kinase (ATR) are members of phosphatidylinositol 3-kinase (PIKK) family, belonging to serine/threonine kinase, one of the key kinases in DNA damage response (DDR) and DNA repair pathway. This paper reviews the latest progress in the ATR inhibitor field including mechanism of action (MOA), therapeutic applications, and the combination therapy from the perspective of medicinal chemistry. It also discusses the possible challenges and future directions of developing ATR inhibitor antitumor drugs, which could provide the scientists in this field the convenience for access the information and application guidance for clinical studies.

This study was aimed to explore the effect of total flavonoids and saponins from Huang-Qi Ge-Gen (HQGG) decoction on blood glucose (BG), serum lipid, interleukin-12 (IL-12) and interleukin-15 (IL-15) of liver in diabetes mellitus (DM) rats, in order to investigate their interactions in regulating DM processes. A total of 66 SD rats were randomly divided into 6 groups, which were the normal group, model group (A1B1), control group, total flavonoids group (A2B1), total saponins group (A1B2), and total flavonoids and saponins group (A2B2), with 11 rats in each group. Except the normal group, other groups were intraperitoneal injected with streptozotocin (STZ). And the experiment was according to 2×2 factorial design experiment scheme. The BG was determined before STZ injection and 7 days after the STZ injection. After 30 days, BG, serum lipid, IL-12 and IL-15 of liver were tested. Related indexes were calculated to the weighted composite score. Main and interactive effect of total flavonoids and saponins were studied according to the factorial design experiment scheme. The results showed that compared with the normal group, all indexes of model group showed statistical differences (P<0.05). Total flavonoids and saponins from HQGG decoction can effectively reduce BG, without any interactions between them. Both the total flavonoids and total saponins can reduce serum cholesterol (CHO), triglyceride (TG), liver IL-12 and IL-15. And there were interactive effects. The single use of herb achieved better effects than the combination. It was concluded that total flavonoids and saponins from HQGG decoction can reduce BG, CHO, TG, and liver IL-12 and IL-15 levels in rats. However, the regulation of total flavonoids and saponins on indexes mentioned above showed no additive effect.
