Objective:To evaluate the effect of trehalose on oxygen-glucose deprivation and restoration (OGD/R) injury in H9C2 cells and the role of solute carrier family 7 member 11- (SLC7A11)-glutathione peroxidase 4 (GPX4) signaling pathway.Methods:Well-grown H9C2 cells were divided into 4 groups ( n=24 each) by the random number table method: control group (group C), OGD/R group (group O), OGD/R+ trehalose group (group OT) and OGD/R+ trehalose+ erastin group (group OTE). The cells were normally cultured in group C. In O, OT and OTE groups, the DMEM medium was replaced with EBSS medium, the cells were exposed to 5% CO 2-95% N 2 in an incubator at 37 ℃ for 6 h, and then the medium was replaced with DMEM medium supplemented with 6% fetal bovine serum to restore oxygen and glucose supply for 24 h. In group OT, trehalose at a final concentration of 50 mmol/L was added during restoration of oxygen and glucose supply. In group OTE, the SLC7A11 inhibitor erastin at a final concentration of 10 μmol/L was added at 8 h before oxygen-glucose deprivation, and trehalose at a final concentration of 50 mmol/L was added during restoration of oxygen and glucose supply. The cell viability, lactic dehydrogenase (LDH) activity, contents of glutathione (GSH), malondialdehyde (MDA) and iron, and reactive oxygen species (ROS) levels were measured at 24 h of restoration of oxygen and glucose supply. The expression of SLC7A11, GPX4, long-chain fatty acyl coenzyme A synthetase 4 (ACSL4), and ferritin heavy chain 1 (FTH1) was detected by Western blot. The structure of the mitochondrial morphology was observed with a transmission electron microscope. Results:Compared with group C, the cell viability and GSH content were significantly decreased, the LDH activity, contents of MDA and iron, and ROS level were increased, the expression of SLC7A11, GPX4 and FTH1 was down-regulated, and the expression of ACSL4 was up-regulated in group O ( P<0.05). Compared with group O, the cell viability and GSH content were significantly increased, the LDH activity, contents of MDA and iron, and ROS level were decreased, the expression of SLC7A11, GPX4 and FTH1 was up-regulated, and the expression of ACSL4 was down-regulated in group OT ( P<0.05). Compared with group OT, the cell viability and GSH content were significantly decreased, the LDH activity, contents of MDA and iron, and ROS levels were increased, the expression of SLC7A11, GPX4 and FTH1 was down-regulated, and the expression of ACSL4 was up-regulated in group OTE ( P<0.05). Conclusions:Trehalose can inhibit ferroptosis by activating the SLC7A11-GPX4 signaling pathway, thereby attenuating OGD/R injury in H9C2 cells.

Chicoric acid， a hydroxycinnamic acid with the molecular formula C₂₂H₁₈O₁₂， is an important active ingredient in Taraxacum mongolicum， Echinacea purpurea， Cichorium intybus and other natural plants， and it helps plants protect themselves from insects and infection from viruses， bacteria， fungi， and nematodes. Modern pharmacological research suggests that chicoric acid has significant bioactivities such as anti-inflammatory， antioxidant， immune-regulating， antibacterial， antiviral and anti-tumor properties. The first reported bioactivity of chicoric acid is its inhibitory effect on human immunodeficiency virus （HIV）. With the development and application of molecular biology and related technologies， the inhibitory activities of chicoric acid on other viruses as well as its mechanism of action have been frequently reported. Another study indicates that chicoric acid has significant inhibitory effects on different pathogenic bacteria. This paper summarized the research progress on the antiviral and antibacterial effects of chicoric acid through a comprehensive review of relevant literature in China and abroad in the past 20 years. Studies have shown that chicoric acid has significant inhibitory activities against various viruses such as HIV， hepatitis B virus （HBV）， respiratory syncytial virus （RSV）， and herpes simplex virus （HSV）， as well as different pathogenic bacteria such as Staphylococcus aureus， Yersinia enterocolitica and Mycobacterium tuberculosis. This study is expected to provide references for in-depth research on chicoric acid against pathogenic microorganisms and antiviral and antibacterial study of traditional Chinese medicine.

【Objective】 To investigate the risk factors of vasovagal reactions(VVR) related to plasma donation, so as to put forward clinical suggestions for early identification and accurate intervention of high-risk groups to ensure the safety of plasma donation. 【Methods】 The demographic characteristics(i.e. gender, age, weight) and records of plasma donors(donation history, pulse before plasma donation, duration of collection, etc.) were collected from July to December 2019 in a region of Sichuan. Based on logistic regression analysis, the correlation between these factors and the risk of VVR was explored. 【Results】 The information of 69 172 donors was collected, and the incidence of VVR was 7.04‰. The risk of VVR was reduced by 99% in the group with plasma collection duration less than 30 minutes compared with the group with plasma collection duration more than 50 minutes(OR, 0.01; 95% CI, 0.00~0.01; P<0.001). The risk of male group was 94 % lower than that of female group(OR, 0.06; 95% CI, 0.04~0.10; P<0.001). Compared with the 45~50 kg group, the risk of weight greater than 80 kg group decreased by 80%(OR, 0.20; 95% CI, 0.09~0.42; P<0.001). The risk of repeated donation group was 34 % lower than that of the first time donation group(OR, 0.66; 95% CI, 0.47~0.91; P<0.001). The risk of VVR in the group with pulse greater than 90 bpm before plasma donation was 2.43 times that in the 60~69 bmp group(OR, 2.43; 95% CI, 1.75~3.36; P<0.001). 【Conclusion】 Duration of plasma collection, gender, weight, frequency of plasma donation, pulse before plasma donation and donor status are independent risk factors for plasma donation-related VVR. Among them, plasma collection duration, gender and weight were the main independent risk factors for plasma donation-related VVR. For donors with plasma collection duration more than 50 minutes, female and low weight, higher risk of VVR was presented and more preventive intervention should be given.

Objective:To investigate the safety, efficacy and application indication of intra-operative cell salvage (IOCS) in cesarean section.Methods:A total of 1 265 pregnant women who received IOCS blood transfusion during cesarean section in 11 tertiary A hospitals from August 2016 to January 2019 were collected and divided into <1 500 ml group (796 cases) and ≥1 500 ml group (469 cases) according to the amount of blood loss during cesarean section. The general clinical data, ultrasonic imaging data, perinatal and puerperium indicators were analyzed retrospectively. The risk factors of intraoperative blood loss ≥1 500 mL using IOCS transfusion were analyzed by logistic multivariate regression.Results:(1) A total of 848 001 ml of blood was recovered and a total of 418 649 ml of blood was transfused in 1 265 pregnant women who received IOCS transfusions, which was equivalent to 23 258 U red blood cell suspension, greatly saving medical resources. The intraoperative blood loss in <1 500 ml group and ≥1 500 ml group was 800 ml (300-1 453 ml) and 2 335 ml (1 500-20 000 ml), respectively. No amniotic fluid embolism, severe adverse reactions, shock and death occurred in the two groups. (3) Multivariate regression analysis showed that age ≥35 years ( OR=1.5, 95% CI: 1.1-1.9), prenatal hemoglobin level <110 g/L ( OR=1.7, 95% CI: 1.3-2.2), history of uterine surgery ( OR=1.8, 95% CI: 1.3-2.6), placenta previa ( OR=1.9, 95% CI: 1.1-3.1), placenta accreta ( OR=2.6, 95% CI: 1.8-3.9), blood pool in the placenta ( OR=1.6, 95% CI: 1.1-2.3), abnormal posterior placenta muscle wall ( OR=1.8, 95% CI: 1.2-2.6), placenta projecting to the anterior uterine wall ( OR=3.0, 95% CI: 1.3-7.0) were risk factors for blood loss ≥1 500 ml in obstetric transfusion using IOCS technique, with statistical significance (all P<0.05). Conclusion:IOCS is safe and effective in cesarean section, which could save the medical resources and reduces medical expenses, however, it is necessary to strictly master the application indication.
