Objective:To review the application of internet cognitive behavioral therapy (CBT) in perinatal women with negative emotions, point out the limitations of existing studies, and put forward development suggestions for future research.Methods:Using the Scope review guide published by Joanna Briggs Institute as the methodological framework, eight Chinese and English databases including China National Knowledge Infrastructure (CNKI), Wanfang, PubMed and Web of Science were searched until July 1, 2024, and the literatures were collected and analyzed.Results:A total of 18 literatures were included. The interventionists of internet cognitive behavioral therapy were mostly psychologists; the intervention methods were mostly in the form of partial participation of therapists, and the intervention platforms were mostly websites. The intervention content was centered on mental health education, emotional monitoring, cognitive reconstruction, behavioral activation training, and problem solving. There were 15 studies that demonstrated that internet cognitive behavioral therapy was effective, and three studies showed that internet cognitive behavioral therapy was not effective in improving negative emotions in perinatal women, but perinatal women responded to treatment.Conclusions:The Internet cognitive behavioral therapy can effectively improve the negative emotions of perinatal pregnant women, but the long-term effect is not clear. Future studies can expand the sample size and follow up the effect for a long time.

Objective To investigate the effect of vitamin D supplementation in early pregnancy on the incidence and glucose metab-olism of high-risk women with gestational diabetes mellitus.Methods Pregnant women who had regular prenatal examination in Hefei First People's Hospital from December 2019 to May 2022 with serum 25(OH)D level＜30ng/ml,expected date of delivery ≥ 35 years or pre-pregnancy body mass index(BMI)≥24kg/m2were selected.They were randomly divided into intervention group(86 cases)and control group(94 cases).The intervention group,took 1200IU/d vitamin D3 capsules orally from the first trimester of pregnancy to the second trimester of pregnancy[the date of oral glucose tolerance test(OGTT)examination for pregnant women];the control group was not given vitamin D3 capsules,and pregnant women with vitamin D deficiency or insufficient were recommended to take vitamin D3 cap-sules or calcium tablets containing vitamin D.Results The levels of vitamin D in the first and second trimester of pregnancy were 12.986± 5.654ng/ml and 31.277±9.856ng/ml in the intervention group,and the difference was statistically significant(P＜0.001).The inci-dence of gestational diabetes mellitus in control group and intervention group was 24.5％and 20.9％,and the difference was not statisti-cally significant(P＞0.05).There were no significant difference in fasting blood glucose,fasting insulin,1h blood glucose,2h blood glucose and homeostasis model assessment insulin resistance index(HOMR-IR)between the intervention group and the control group in the second trimester of pregnancy(P＞0.05).Conclusion Vitamin D supplementation in early pregnancy can only significantly improve the level of vitamin D in pregnant women,and almost make it reach sufficient state,but has no obvious effect on the risk of gestational dia-betes mellitus and glucose metabolism.
