Poly(C)-binding protein 1(PCBP1)is a multifunctional RNA-binding protein involved in a series of processes such as gene transcription,selective modification,translation and regulation of iron metabolism.This pa-per explores the pathway through which PCBP1 inhibits ferroptosis during the research on PCBP1-related diseases,such as bladder cancer and head and neck cancer.PCBP1 can reduce the intracellular ferrous iron content to inhib-it ferroptosis through the mechanisms like inhibiting ferritinophagy,promoting the transfer of iron ions to ferritin or iron-dependent enzymes,stabilizing the labile iron pool within cells and facilitating the formation of[2Fe-2S]clus-ters.PCBP1 can also reduce the generation of lipid peroxides and enhance the resistance to oxidative stress thus to reduce the level of intracellular reactive oxygen thereby inhibiting ferroptosis.

Objective:To investigate the clinical features of placental thrombosis complicated with fetal growth restriction(FGR),and to analyze its diagnosis and treatment methods. Methods:Combined with reviewing the relevant literatures, the clinical data of a case of placental thrombosis complicated with FGR was retrospectively analyzed. The patient with 32 1/7 weeks of gestation was hospitalized due to placental blood sinus found one month ago;at the same time FGR was found by ultrasound examination. The patient was intravenously given nutritional support treatment such as amino acid and glucose.At the same time, the patient was continuously given low-flow oxygen. Results:The patient received cesarean section at 35 2/7 weeks of gestation and a baby girl with 1 280 g weight and 32 cm length was gained;many blood sinus in the maternal surface of placenta were seen with the largest diameter of 3-4cm;the placenta was hypertrophic, weighted 540 g .After operation,the newborn was transferred to Department of Neonatology and followed up for 1 month.1 month later, the infant could eat by herself, other physical examinations were finished without any obvious abnormal findings and the newbron discharged from hospital after recovery. Conclusion:Placental thrombosis complicated with FGR is very common in clinic and this disease severely endangers the neonatal health. Early diagnosis and reasonable treatment can improve the pregnancy outcomes.
