Rapeseed oil is one of the major raw materials for biodiesel production. The bottleneck of rapeseed oil-based biodiesel production at present is high cost of raw materials, which generally accounts for about 75% of total production cost. Current status and principal problems concerned in the production of biodiesel from rapeseed oil in China and other countries were introduced, based on which it was proposed to grow high-erucic acid rape in existing winter fallow fields and jointly produce biodiesel, erucic acid and its derivative products, and other highly valuable by-products such as glycerin and sterols from high-erucic acid rapeseed oil. The feasibility of this development strategy was analyzed in terms of product and market demand potential, economic benefits of enterprises, techniques and conditions of production, and source of raw materials. It was believed that the implementation of the strategy in China was of great significance in realizing rise and sustainable development of rapeseed oil-based biodiesel production, improving quality of biodiesel, promoting the development of biochemical engineering and many other industries, as well as in building a socialist new countryside.

Objective:To explore the effect of sarpogrelate on platelet function in patients at the bridging stage before coronary artery bypass grafting (CABG).
Methods: A total of 40 consecutive patients with peripheral artery stent and scheduled for CABG in our hospital from 2011-05 to 2013-04 were enrolled in this study. The patients were randomly divided into 2 groups, Low molecular weight heparin (LMWH) alone group, n=19 and Sarpogrelate+LMWH group, n=21. The medications started at 5-7 days before CABG and stopped at 24 h before CABG. The platelet inhibition rates (platelet aggregation induced by collagen+ serotonin) were examined and compared between 2 groups at the baseline (before randomization), 24h and 1h before CABG respectively.
Results: The platelet inhibition rates were similar between 2 groups at the baseline (87.33 ± 6.82) % vs (86.11 ± 6.87) %, P=0.577 and 1h before CABG (62.60 ± 12.39) % vs (56.19 ± 14.99) %, P=0.148. At 24h before CABG, the platelet inhibition rate in Sarpogrelate+LMWH group was higher than that in LMWH alone group (83.87 ± 8.99)%vs (63.13 ± 10.88)%, P<0.001. Compared with the baseline, the falling range of platelet inhibition was lower in Sarpogrelate+ LMWH group at 24h before CABG, (3.46 ± 6.18) % vs (22.98 ± 9.43) %, P<0.001 and the falling range was similar between 2 groups at 1h before CABG (24.73 ± 14.19)%vs (29.92 ± 14.28)%, P=0.257.
Conclusion: Sarpogrelate + LMWH may result better platelet inhibition rate with quicker recovery of platelet function upon the medication stopping, which might be a feasible management in patients at the bridging stage before CABG.

Objective To investigate the effect of duodenal-jejunal bypass(DJB) on glucose metabolism and the expression of ileum proglucagon mRNA in Goto-Kakizaki (GK) type 2 diabetic rats.Methods 18 male GK rats and 1 8 male Wistar rats were randomly divided into 4 groups:GK operation group(group A),GK sham operation group(group B),Wistar operation group (group C),Wistar sham operation group (group D).There were 9 rats in each group.The fasting blood glucose and GLP-1 levels were measured before and at the 8th weekafter surgery.Oral glucose tolerance test was measured,and the area under blood glucose concentration curve wascalculated.Ileum tissues were obtained 8 weeks postoperatively and reverse transcriptase polymerase chain reac-tion was used to detect ileum PG mRNA expression after the operation.Results At the 8th week after surgery,the fasting blood glucose of group A decreased from(8.73 ± 1.30) mmol/L to(5.86 ±0.57) mmol/L(P ＜0.05).Area under blood glucose concentration curve decreased from preoperative(60.23 ± 5.14)mmol · h/L to (47.80 ±1.79) mmol· h/L(P ＜ 0.05).Fasting serum GLP-1 in group A increased from (7.69 ± 0.74) pmol/L to (29.00 ±4.85) pmol/L while postprandial GLP-1 increased from(15.74 ± 5.71) pmol/L to (45.78 ± 7.26) pmol/L (P ＜0.05).At the 8th week after surgery,the ileum PG mRNA level in group A was significantly higher than that in group B(P ＜ 0.05).Conclusions DJB can directly improve glucose metabolism in non-obese type 2 diabetic rats,and the operation has no hypoglycemic effect on normal blood glucose.The increased expression of ileum PG mRNA might contribute to the hypoglycemic effect of the surgery.

Objective To investigate plasma glutathione S-transferase(GSTs) activity and GSTP1 gene Ile105Val polymorphism in Bijie City, Guizhou Province, a coal-burning fluorosis endemic area. Methods One hundred and sixty villagers from Yachi Twon using non-improved cooking stoves were selected as the non-intervened group in Bijie City, Guizhou Province where coal-burning fluorosis was prevailing; 153 villagers as the intervented group were chosen from Changchun Twon, where cooking stoves were improved; 151 villagers were served as the control group from Baiyunshan Twon, Changshun County without endemic fluorosis. The activity of GSTs was tested by colorimetric analysis with spectrophotometer. The genotype of the GSTP1 gene Ile105Val polymorphism, presenting as either homozygous wild-type (AA), or heterozygous mutation type (AG), or homozygous mutation type (GG), was detected through the PCR-RFLP procedure. Results The activity of GSTs in plasma of non-intervened group [(12.44±4.97) kU/L]was significantly lower than that of intervened group (P < 0.05), and that of intervened group[(20.78±6.20)kU/L]was significantly lower than that of control group[(24.30±6.27)kU/L, P< 0.05]. The difference of the enzyme activity of three groups were statistically significant (F = 51.71, P < 0.05), but this enzyme activity did not vary significantly in each sex of each grnup(P > 0.05). Compared intervened group [AA:67.3%(103/153), AG:29.4%(45/153),GG:3.3%(5/153)]and non-intervened group[AA:66.9%(107/160), AG:30%(48/160), GG:3.1%(5/160)]with control group[AA:74.8%(113/151), AG:25.2%(38/151), GG:0 (0/151)], the Ile105Val polymorphism site of GSTP1 gene had significant difference(χ2= 6.04,6.07, both P< 0.05), but not significant between intervened and non-intervened groups(χ2 = 0.02, P>0.05). Conclusions Fluorosis can decrease the activity of GSTs and introduce the GSTP1 gene Ile105Val polymorphism, intervention with the fluorine intake will improve the effect of fluoride on the body.

Objective To explore the correlation between myeloperoxidase (MPO) genetic variation and coal-burning endemic fluorosis, and to understand the influence of integrated intervention including stove changes and health education on people’s health in the area. Methods In 2007, coal-burning endemic fluorosis disease areas were selected in Bijie City, Guizhou Province. No stove changes in Yachi Town, 150 patients with dental fluorosis were selected as fluorosis non-intervention group, and the intervention group was 150 patients in Changchun Town where the stoves were changed 2 years ago. The population in control group was selected in an area with non-endemic fluorosis in Changshun County. The mRNA expressions of MPO in leukoxytes were detected by real-time PCR. HepG2 cells were cultured in vitro and divided into four groups: pGL3-A group, pGL3-G group, pGL3-Control group and pGL3-Basic group. pGL3-A and pGL3-G were recombinant plasmid, while pGL3-Basic as a blank control and pGL3-Control as a positive one. The internal reference plasmid pRL-TK co-transfected the HepG2 cells with pGL3-G, pGL3-A, pGL3-Basic and pGL3-Control, respectively. The influence of sudden change of MPO gene promoter on the gene transfection activity was evaluated by a dual luciferasereporter gene system. Results The expression level of MPO mRNA in peripheral blood leukocytes in non-intervention group(0.054 ± 0 . 003 ) were higher than control and intervention groups (0.019 ± 0.004,0.019 ± 0.003, all P<0.05), and no significant change was found between intervention group and control group(P>0.05). After the MPO-463G/A locus genetic variation occured, the luciferase reporter gene expression level of the recombinant plasmid pGL3-G(0.753 4 ± 0.086 6) was higher than that of the pGL3-A(0.490 0 ± 0.022 3, P < 0.05). Conclusions The study on MPO gene promoter-463G/A locus has prompted that MPO gene allele may be a protective factor to coal-burning fluorosis. The integrated interventions have a role in the prevention and treatment of endemic fluorosis.
