ABSTRACT Objective: To look into the effects of different anesthesia methods on the labor process and the expression of serum estrogen and progesterone in primiparas with painless labor. Methods: 60 primiparas receiving painless labor were selected as the research objects, and they were divided into either a Spinal & Continuous epidural anesthesia group (n = 30) or a continuous epidural anesthesia group (n = 30), anesthesia is administered using the corresponding anesthesia method. The authors compared serum estrogen and progesterone, inflammatory index expression, pain degree and neonatal health status in different periods. Results: At T2 and T3, serum P, LH, FSH and E2 levels in the Spinal & Continuous epidural anesthesia group were signally lower than those in the Spinal & Continuous epidural anesthesia group (p < 0.05). Spinal & Continuous epidural anesthesia group harbored faster onset and longer duration of sensory block and motor block than the Continuous epidural anesthesia group (p < 0.05). SAS and SDS scores of the Spinal & Continuous epidural anesthesia group were clearly lower than those of the Continuous epidural anesthesia group (p < 0.05). VAS score and serum TNF-α, IL-6 levels of pregnant women in the Spinal & Continuous epidural anesthesia group were memorably lower than those in the Continuous epidural anesthesia group at T2 and T3 (p < 0.05). The total incidence of postoperative complications in the Spinal & Continuous epidural anesthesia group was distinctively lower than that in the Continuous epidural anesthesia group (p < 0.05). Conclusion: Spinal anesthesia combined with continuous epidural anesthesia has a better anesthesia effect in the painless labor of primiparas, which can effectually ameliorate the labor process and the expression of serum estrogen and progesterone.

Abstract The rutin-hydrolyzing enzyme (RHEs) catalyse hydrolysis of rutin to quercetin. In this study, a RHE purified from natural tartary buckwheat flour (FtRHE) exhibited β-glucosidase activity. It was highly active on cello-oligosaccharides and p-nitrophenyl-β-D-glucopyranoside (pNPG). FtRHE exhibited optimum β-glucosidase activity at 40 °C and pH 4.0, which was elevated by the presence of Ca2+, suggesting that Ca2+ may act as a co-factor for its activation. The Km and Vmax of FtRHE were 0.22 mM and 310.48 U/mg, respectively, when pNPG was the substrate. FtRHE retained only 6.6% activity in the presence of 1.5 M glucose, indicating that glucose acted as its inhibitor. This study demonstrates β-glucosidase activity of a RHE from natural tartary buckwheat flour and provides better understanding of its role in glycoside metabolism, establishing a basis for further investigations.
