ABSTRACT
Background: Severe preeclampsia is the main cause of maternal mortality. The correlation between vitamin D and hypertensive disorder of pregnancy is a controversial topic at present. Whether vitamin D can be used as an index to predict the risk of preeclampsia and when to supplement vitamin D in clinic has become a relatively popular research content. This study aimed to correlate vitamin A and D with hypertensive disorder of pregnancy and to reduce the risk of hypertension in pregnancy. Methods: This is a Prospective cohort study on 958 pregnant females. The patients were divided into two groups, namely, treatment group and Pregnancy Induced Hypertension (PIH) group. Liquid chromatography-tandem mass spectrometry and highperformance quid gel electrophoresis were used to find vitamin A and D in the blood of each group (HPLC). Results: There has not been a big difference in between PIH group and the placebo group (p>0.5). Preeclampsia collection and simple preeclampsia group there has been a statistical change in cesarean unit amount and impulsive transfer (p<0.05). The study further found that There is no rise in the likelihood of mild pregnancy complications, and the thing that is different would not be statistically important (p>0.05). Serum vitamin D level is less than 20 ng/ml, which is a risk factor for preeclampsia. Conclusion: The lack of vitamin A may be associated with the occurrence of hypertensive disorders during pregnancy and the progression of the disease. The lack of vitamin A may increase the risk of severe preeclampsia risk increased.
ABSTRACT
OBJECTIVE：To study the improvem ent effects of total flavonoids from Morus alba on glycolipid metabolism ， inflammation and oxidative stress in gestational diabetes mellitus （GDM）model rats ，and to investigate the potential mechanism. METHODS：After feeding high fat diet for 8 weeks，female SD rats with FBG ＜6.67 mmol/L were caged with male SD rats . Pregnant female rats were randomly divided into control group ，GDM group ，M. alba total flavonoids low-dose ，medium-dose and high-dose groups （50，100，200 mg/kg），with 10 rats in each group. Except for control group ，other groups were given intraperitoneal injection of streptozotocin 25 mg/kg once to induce GDM model. After injection ，rats in each administration group were given corresponding drugs intragastrically ，control group and GDM group were given normal saline 10 mL/kg intragastrically ， once a day ，for consecutive 18 days. The levels of FBG were determined on the 3rd，7th and 18th day of pregnancy （G3d，G7d and G18 d）；the levels of blood lipids （TG，TC，LDL-C，HDL-C）and inflammatory factors （TNF-α，IL -6，IL-8），oxidative stress indicators（MDA，SOD，GSH，CAT）in serum were determined on G 18d. The protein and mRNA expressions of PPARγ and NF-κB， the expression of AMPK mRNA and p-AMPK protein were measured by Real-time-PCR and Western blotting. RESULTS ： Compared with control group ，the levels of FBG （G3d，G7d，G18d），TG，TC，LDL-C，TNF-α，IL-6，IL-8 and MDA ，protein and mRNA expression of NF-κB in GDM group were significantly increased，while the levels of SOD ，GSH and CAT ，the expressions of PPARγ protein and mRNA，AMPK mRNA and p-AMPK fcksjf@126.com protein were significantly decreased （P＜0.01）. Compared with GDM group ，the levels of FBG （G3 d，G7 d，G18 d），TG， huawei99@163.com TC，LDL-C in M. alba total flavonoids medium-dose and high- dose groups and the levels of TNF-α，IL-6，IL-8 and MDA ，protein and mRNA expression of NF-κB in M. alba total flavonoids groups were significantly decreased ；the levels of SOD ，GSH and CAT ，the expressions of PPARγ protein and mRNA， AMPK mRNA and p-AMPK protein were significantly increased （P＜0.05 or P＜0.01）. CONCLUSIONS ：Total flavonoids from M. alba can improve the glycolipid metablism ，inflammation and oxidative stress in GDM model rats ，the mechanism of which may be related to the activation of PPARγ pathway.
