Preoperative Study of the Correlation Between BDNF-TrkB Signaling Pathway Expression Levels in Cerebrospinal Fluid and Blood and Postpartum Depression
China200 participantsStarted 2025-05-01
Plain-language summary
This single-center prospective observational study will screen 200 parturients with combined lumbo-epidural anesthesia in the First People's Hospital of Lianyungang City, collect the basic information of the patients, as well as the scores of PSQI, STAI, NRS, SSRS and other scales one day before surgery, and analyze their effects on the expression level of BDNF. On the day of surgery, 10mL of peripheral arterial blood and 3 mL of cerebrospinal fluid were collected, and the expression levels of BDNF-TrkB signaling pathway (ProBDNF, mBDNF, TrkB, P-CREB and ALB) were measured, respectively. The patient's EPDS and HAMD-21 scores were evaluated and collected by a professional psychologist at 1 day before surgery, 7 days after surgery, and 42 days after surgery, and the correlation between BDNF expression level and the occurrence of postpartum depression was statistically analyzed, as well as which in cerebrospinal fluid and blood was more sensitive for predicting postpartum depression.

What they're measuring
1
Correlation between the expression level of BDNF-TrkB signaling pathway (mBDNF, proBDNF) in cerebrospinal fluid and blood and postpartum depression;
Timeframe: Blood and cerebrospinal fluid samples were collected before anesthesia administration on the day of surgery, placed in a -80 degree Celsius freezer, and mBDNF and proBDNF concentrations were measured within 3 months after sample collection.
