Objective To investigate the epidemiological characteristics and influencing factors of Femoral Artery Compression-Related Skin Complications Around the Puncture Site(FACR-SCAPS)in patients with primary hepatocellular carcinoma(HCC)undergoing transarterial chemoembolization(TACE).Methods A multicenter cross-sectional study was conducted using convenience sampling.A total of 1 573 HCC patients who underwent TACE between April 2023 and October 2024 were recruited from interventional radiology departments,oncology units,and specialized centers across 10 hospitals in Beijing,Tianjin,Shandong,Hebei,Qinghai,and Inner Mongolia.Descriptive statistics,univariate analysis,and multivariate logistic regression were used to explore the epidemiological characteristics and influencing factors of FACR-SCAPS in this population.Results Among the 1 573 primary HCC patients undergoing TACE interventional therapy,FACR-SCAPS occurred in 28.99％(456/1 573),with a total of 476 complication instances recorded(30.26 per 100 patients).Patients with a single complication accounted for 96.93％,whereas those with multiple complications constituted 3.07％.The most prevalent types of complications were skin erythema,skin ecchymosis,and hard lumps formation,collectively accounting for 96.49％of all complications.Hematoma,blisters,and rupture complications collectively accounted for only 4.61％.Logistic regression analysis revealed that peak diastolic blood pressure during compression(OR=1.024,95％CI:1.013-1.035,P＜0.001),use of rotary compression hemostasis devices(OR=3.220,95％CI:2.120-4.891,P＜0.001),elevated PT-INR(OR=19.630,95％CI:6.039-63.810,P＜0.001),and anticoagulant use within the last three months(OR=1.909,95％CI:1.064-3.427,P=0.030)were significant influencing factors associated with FACR-SCAPS post-TACE.Conclusion FACR-SCAPS is commonly seen among primary HCC patients after TACE,its risk factors include peak diastolic blood pressure during compression,use of rotary compression devices,elevated PT-INR,and recent anticoagulant use.

Objective To study the levels of serum Periostin and interleukin(I1-)-18 in preterm infants with bronchopulmonary dysplasia(BPD),and to analyze their correlation with the severity of the disease and their predictive value for BPD.Methods A total of 62 preterm infants with BPD diagnosed and treated in the hospital from January 2019 to January 2022 were retrospectively selected as the BPD group,and 80 preterm in-fants without BPD during the same period were selected as the non-BPD group.According to the severity of BPD,the infants with BPD were divided into mild subgroup(22 cases),moderate subgroup(24 cases)and se-vere subgroup(16 cases).The serum levels of Periostin and IL-18 were detected by enzyme-linked immu-nosorbent assay.Pearson correlation analysis was used to analyze the correlation between the clinical parameters.Multivariate Logistic regression was used to analyze the influencing factors of BPD,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for BPD.Results Compared with the non-BPD group,the BPD group had a significantly higher proportion of infants with pulmonary surfactant(PS)use,neonatal respiratory distress syndrome,apnea,patent ductus arteriosus,and serum levels of Periostin and IL-18,as well as a significantly longer duration of mechanical ventilation,noninvasive respiratory support,and length of hospital stay.The lung function parameters[tidal volume per kilogram(VT/kg),ratio of time to peak tidal expiratory flow to time(TPTEF/TE),ratio of volume to peak tidal expiratory flow to volume(VPEF/VE),expiratory flow at 50％tidal volume(50％TEF),expiratory flow at 75％tidal volume(75％TEF)]and 1,5 min Apgar score of BPD group were lower than that of non-BPD group,and the differences were statistically significant(P＜0.05).The serum levels of Periostin and IL-18 in mild subgroup,moderate subgroup and severe subgroup were increased in turn.The levels of serum Periostin and IL-18 were negatively correlated with pulmonary function indexes(VT/kg,50％TEF,75％TEF,TPTEF/TE,VPEF/VE,P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for BPD(P＜0.05),and PS was a protective factor(P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for the severity of BPD(P＜0.05).The area under the curve(95％CI)of serum Periostin and IL-18 alone and in combination for predicting BPD were 0.841(0.814-0.899),0.863(0.820-0.897),0.922(0.878-0.949),respectively.The sensitivity and specificity of combined prediction were 0.902 and 0.825,respectively.The area under the curve of the combination of the two indica-tors for predicting BPD was greater than that of each index alone,and the difference was statistically signifi-cant(Z=5.357,4.894,P＜0.001).Conclusion The levels of serum Periostin and IL-18 are increased in in-fants with BPD,which are related to the severity of BPD and lung function.The combination of serum Perios-tin and IL-18 has a high predictive value for BPD.

Objective To explore the level of autophagy induced by oxygen glucose deprivation/reperfusion(OGD/R) injury in L02 cell.Methods L02 cells were cultured to establish the model of OGD/R injury and simulate clinical hepatic ischemia-reperfusion injury.The L02 cells were randomly divided into 5 groups : normal control group, oxygen-glucose deprivation 6 h/reperfusion 1,3,6,12 h group (OGD 6 h/R 1,3,6,12 h).Then observe the form changes of the L02 cells by optical microscope.The appreciation of the company's relative L02 cells was detected by MTT.The expression of autophagy related proteins such as Beclin-1, LC3 and p62 were evaluated by Western blot.Results Compared with the normal control group, the form damaged and the cells proliferation activity of L02 cells in the OGD/R group were gradually increased in a time-dependent manner.Compared with the normal control group, autophagy related proteins LC3 , Beclin-1 were increased at OGD 6 h/R 1 h.The expression of LC3 was gradually increased as the time went on and was increased gradually at OGD 6 h/R 6 h, reached a peak at OGD 6 h/R 12 h(P<0.01).The expression of Beclin-1 was gradually increased as the time went on and was increased gradually at OGD 6 h/R 6 h and OGD 6 h/R 12 h (P<0.01).The expression of p62 had no obvious change at OGD 6 h/R 1 h and OGD 6 h/R 3 h, began to increase sharply at OGD 6 h/R 6 h and reached a peak at OGD 6 h/R 12 h(P<0.01).Conclusion Our data suggests that oxygen-glucose deprivation/reperfusion may increase the level of autophagy and lead to autophagic cell death in L02 cell.

Objective To evaluate the effect of propofol on autophagy during oxygen-glucose deprivation and restoration (OGD/R) in human liver cells.Methods Human hepatic HL-7702 cells at the logarithmic growth phase were seeded into culture plates and randomly divided into 3 groups (n =12 each) using a random number table:control group (group C),OGD/R group,and propofol + OGD/R group (group P+OGD/R).The cells were cultured in normal culture medium in group C.In OGD/R and P+OGD/R groups,the cells were subjected to O2-glucose deprivation for 6 h followed by restoration of O2-glucose supply for 12 h.Propofol with a final concentration of 50 mmol/L was added at 10 min before oxygen-glucose deprivation.The cell viability was detected by MTT assay.The expression of autophagy-related proteins such as microtubule-associated protein light chain 3 (LC3) and Beclin-1 was evaluated by Western blot.Immunofluorescence was used to determine the number and distribution of autophagosomes.Results Compared with group C,the cell viability was significantly decreased,the expression of LC3 and Beclin-1 was significantly up-regulated (P＜0.05),and the number of autophagosomes was significantly increased in OGD/R and P+OGD/R groups.Compared with group OGD/R,the cell viability was significantly increased,the expression of LC3 and Beclin-1 was significantly down-regulated (P＜0.05),and the number of autophagosomes was significantly decreased in group P+OGD/R.Conclusion The mechanism by which propofol reduces OGD/R injury is probably related to inhibition of autophagy in human liver cells.
