The selectivity to methacrolein was significantly improved by the addition of Cs, which could probably enhance the dehydrogenation ability and weaken the oxygenation ability of the catalyst based on temperature programmed reduction （TPR） analysis investigation. The kinetic studies indicated that the oxidation of isobutylene to methacrolein followed the first-order kinetic behavior.展开更多

Methods: 100 patients with GDM admitted to our hospital from January 2016 to May 2018 were randomly divided into observation group and control group. The control group was treated with routine treatment, while the observation group was treated with 'double C' therapy combined with glibenclamide. Blood sugar level, cesarean section rate, premature delivery rate, pregnancy-induced hypertension rate, fetal distress and incidence of macrosomia were investigated. The levels of omentin-1 and VF in serum were measured. Results: The levels of HbA1c, FPG, 1 h PBG and 2 h PBG in blood of the two groups before delivery were significantly lower than those of the control group (P<0.05), and the levels of HbA1c, FPG, 1 h PBG and 2 h PBG in the observation group were significantly lower than those in the control group (P<0.05);the levels of omentin-1 and VF in the two groups before delivery were significantly higher (P<0.05), and the levels of omentin-1 in the observation group were significantly higher than those in the control group (P<0.05). After treatment, the rate of cesarean section, premature delivery, pregnancy-induced hypertension, fetal distress and macrosomia in the observation group were higher than those in the control group, and the difference was statistically significant (P<0.05). Conclusions: The combination of double C therapy and glibenclamide can improve the curative effect of GDM and the levels of omentin-1 and VF in blood.展开更多
