Objective To investigate the effect of aspirin on oxygen glucose deprivation/reoxygen-ation(OGD/R)-induced injury in mouse hippocampal neuron HT22 cells by regulating ferropto-sis.Methods HT22 cells were randomly divided into control group,model group,low-,medium-and high-dose groups(n=3).Cellular OGD/R injury model was established in the other 4 groups except the control group.Aspirin of 100,200 and 400 μg/ml was used to treat the cells from the above 3 treatment groups,respectively.Cell viability was detected by CCK-8 assay.The contents of TNF-α,IL-1β and IL-6 were detected by ELISA.The contents of SOD,catalase,glutathione,reac-tive oxygen species(ROS),lactate dehydrogenase(LDH),Fe2+and MDA were detected by the corresponding reagent kits.Western blot analysis was performed to determine the expression of solute carrier family 7 members 11(SLC7A11),glutathione peroxidase 4(GPX4)and Acyl-CoA synthase long chain member 4(ACSL4).Results The model group had significantly lower cell vi-ability than the control group(0.49±0.07 vs 1.00±0.12,P＜0.01),but the viability of the low-,medium-and high-dose groups were higher than that of the model group(0.72±0.10 vs 0.49±0.07,P＜0.05;0.87±0.10 vs 0.49±0.07,P＜0.01;0.93±0.07 vs 0.49±0.07,P＜0.01).Compared with the control group,the contents of TNF-α,IL-1β,IL-6,ROS,LDH,Fe2 and MDA and the protein expression of ACSL4 were significantly increased,while the contents of SOD,catalase,glutathione and protein levels of SLC7A11 and GPX4 were obviously decreased in the model group(P＜0.01).Compared with model group,aspirin treatment reversed all above indicators no matter its doses(P＜0.05,P＜0.01).Conclusion Aspirin alleviates OGD/R-induced neuronal in-jury through regulating ferroptosis in mouse neuron HT22 cells in a dose-dependent manner.

Objective To investigate the application value of slice encoding for metal artifact correction-view angle tilting(SEMAC-VAT)in chronic hip pain after total hip arthroplasty(THA).Methods A total of 22 patients who underwent TH A and required MRI reassessment for chronic hip pain were enrolled.All patients underwent coronal and axial short time inversion recovery(STIR)and SEMAC-VAT sequence scans.The prosthesis and surrounding artifact areas of STIR sequence and SEMAC-VAT sequence images were measured respectively.Likert scores were assigned to evaluate prosthesis clarity and visibility of surrounding anatomical structures.The number of abnormal lesions detected was recorded.Paired t-test and rank-sum test were used for comparisons between groups.Results Among the 22 patients,the mean prosthesis and surrounding artifact areas measured in coronal and axial STIR sequences were(73.08±11.28)cm2 and(34.36±8.47)cm2,respectively.For SEMAC-VAT sequences,the corresponding values were(44.30±8.41)cm2 and(23.08±5.85)cm2,respectively.These differences were statistically significant(t=13.942,8.659,P＜0.05).SEMAC-VAT sequences had higher Likert scores on coronal and axial prosthesis clarity and surrounding anatomical structures visibility than STIR sequences(P＜0.05).Additionally,SEMAC-VAT sequences were more effective in detecting abnormal lesions than STIR sequences(P＜0.05).Conclusion Compared to STIR sequences,SEMAC-VAT sequences significantly reduce metal artifacts and enhance image quality in the assessment of chronic hip pain after THA.This technique is advantageous in detecting more positive signs,facilitating the evaluation of hip images in patients with chronic pain after TH A,and subsequently clarifying the etiology of pain.

Objective:To investigate the occurrence of deglutition disorders after extubation in neurosurgery patients, to explore the recovery time and influencing factors, and to provide reference for the development of nursing intervention plan for dysphagia after extubation.Methods:This was a prospective study. A total of 250 patients who underwent oral catheterization under general anesthesia in neurosurgery department and were admitted to the Tenth People′s Hospital of Tongji University from June to December 2022 were selected as the study objects by convenience sampling method. The general demographic and clinical data of the patients were collected to evaluate the occurrence of deglutition disorders after extubation. The outcome and recovery time of deglutition disorders were used as dependent variables. Kaplan-Meier method and Cox proportional hazard regression analysis were used to analyze the recovery time and influencing factors of deglutition disorders after extubation in neurosurgery patients.Results:The incidence of deglutition disorders after extubation was 35.6%(89/250) among 250 cases of neurosurgery patients under general anesthesia by endotracheal intubation, the recovery time of Deglutition Disorders after postoperative extubation was 1 - 16 (5.17 ± 0.43)days. ICU stay days, duration of endotracheal intubation and the first standardized swallowing assessment after extubation were the main influencing factors for the recovery of deglutition disorders in patients with dysphagia after extubation.Conclusions:For patients with deglutition disorders after extubation after neurosurgery, ICU stay days, duration of endotracheal intubation and the first standardized swallowing assessment after extubation affect the process of swallowing function recovery. Medical staff should focus on the risk groups and develop targeted nursing interventions to improve the outcome of patients.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

Objective:To explore the influence of body mass index (BMI) changes on the doses to normal tissues and adverse reactions of the lower digestive system and urinary system in the brachytherapy for cervical cancer.Methods:Clinical data of 80 cervical cancer patients who received radical radiotherapy in our hospital from January 2020 to February 2021 were retrospectively analyzed. All patients received external beam radiation ± chemotherapy + brachytherapy. The delineation method of target areas and organs at risk (OAR) was determined based on the recommended scheme of GEC-ESTRO. The target areas included high risk (HR)-CTV and intermediate risk (IR)-CTV, and OAR consisted of rectum, sigmoid colon, bladder, and small intestine. The target area dose was evaluated by D 90% of the HR-CTV. The OAR volume dose was evaluated by using D2cm3. Correlation analysis was used to compare the dosimetric relationship between BMI and D2cm3, D1cm3 and D0.1cm3 in bladder, rectum, colon and small intestine. Logistic regression analysis was adopted to analyze the risk factors of acute and late adverse reactions in the lower gastrointestinal system and urinary system. Whether BMI was a risk factor was validated. Results:BMI was negatively correlated with the D2cm3, D1cm3 and D0.1cm3 of the small intestine ( P=0.034, 0.024, 0.034), and the correlation coefficients were -0.240, -0.255, and -0.241, respectively. Logistic regression analysis showed that BMI was not a risk factor for the occurrence of acute and late adverse reactions in the lower gastrointestinal system and urinary system. For every 1 Gy increase of D2cm3, D1cm3 and D0.1cm3 in the small intestine, the relative risk of acute adverse reactions in the lower gastrointestinal system was increased by 16.6%, 15.1%,and 12.7%, respectively. Conclusions:In brachytherapy for cervical cancer, there is a negative correlation between BMI and D2cm3, D1cm3 and D0.1cm3 of the small intestine. As the BMI of patients declines, the radiation dose to the small intestine shows an increasing trend, which may increase the risk of acute adverse reactions in the lower gastrointestinal system.

Objective:To investigate the current status of family management function of patients with advanced lung cancer and to explore the correlation between family management function and quality of life in patients with advanced lung cancer.Methods:A total of 187 patients with advanced lung cancer who were admitted to Shanghai Pulmonary Hospital Affiliated to Tongji University from January 2019 to January 2020 were selected as research object. The general data questionnaire, Family Assessment Device (FAD) and WHO Quality of Life-100 (WHOQOL-100) were used to investigate patients with advanced lung cancer to analyze the correlation between family management function and quality of life.Results:The total scores of FAD and WHOQOL-100 of patients with advanced lung cancer were respectively (88.72±11.46) and (102.92±3.65) , which were negatively correlated ( r=-0.896, P<0.05) . Conclusions:The family management function of patients with advanced lung cancer is closely related to the quality of life, and the quality of life of patients can be improved by improving the family management function of patients.

Objective:To explore the effects of phloroglucinol on transfer outcome of in vitro fertilization-embryo transfer (IVF-ET). Methods:Retrospective analysis of 4289 cases of infertility patients treated with IVF-ET in the Department of Reproductive Medicine, the Second Affiliated Hospital of Zhengzhou University from January 1, 2015 to November 30, 2018 was performed. According to the pregnancy outcome, all patients were divided into pregnancy group and non-pregnancy group to analyze the risk factors affecting the pregnancy outcome. According to medication before transfer, all patients were divided into no medication group (group A), preoperative intravenous infusion of atosiban group (group B), preoperative and intraoperative injection of atosiban group (group C) and interoperative intravenous infusion of phloroglucinol group (group D). The pregnancy outcomes, occurrence of adverse reactions during and after treatment were compared among the four groups.Results:Age, number of high-quality embryos, and medication methods before transfer were independent factors influencing pregnancy outcomes in patients undergoing IVF-ET ( P=0.031, P=0.039, P=0.020). The embryo implantation rate, the biochemical pregnancy rate and the clinical pregnancy rate of group D were significantly higher than those in group A (all P<0.001), group B (all P<0.001) and group C ( P<0.001， P<0.001， P=0.001), while the ectopic pregnancy rate was significantly lower than that in group A, group B and group C (all P<0.001). The abortion rate in group D was lower than that in group A ( P<0.001). During treatment period and after treatment, there were no discomfort complains and allergic reactions in the four groups. There were no birth defects in all born babies. Conclusion:The medication method is an independent factor influencing pregnancy outcomes of patients undergoing IVF-ET. Intraoperative intravenous infusion of phloroglucinol can significantly increase embryo implantation rate and pregnancy rate of IVF-ET patients, and reduce their abortion rate.
