Objective:To survey the relationship among parents'rearing style,family conformity and obsess-ive-compulsive symptoms in patients with obsessive-compulsive disorder(OCD).Methods:Totally 216 patients di-agnosed with OCD were recruited(59 cases of mild obsessive-compulsive symptoms,121 cases of moderate obsess-ive-compulsive symptoms,36 cases of severe obsessive-compulsive symptoms).They were assessed with the Yale-Brown Obsessive-Compulsive Disorder Scale(Y-BOCS),Egma Minnen av Bardndosna Uppforstran(EMBU),and Family Accommodation Scale for Obsessive-Compulsive Disorder-Patient Version(FAS-PV).Results:The severe obsessive-compulsive symptom group had the lowest positive parenting style scores.Conversely,they had the high-est negative parental rearing scores and total FAS-PV scores(Ps＜0.01).The ordered logistic regression results showed that male patients had less severe obsessive-compulsive symptoms(OR=0.22).Patients with lower years of education(OR=0.87)and positive parental rearing scores(OR=0.98,0.97)had more severe obsessive-com-pulsive symptoms.Conversely,higher negative paternal rearing scores(OR=1.02)and total FAS-PV scores(OR=1.04)were associated with more severe obsessive-compulsive symptoms.Conclusion:This study suggests that the severity of obsessive-compulsive symptoms is related to parental rearing style and family accommodation.Patients with severe obsessive-compulsive symptoms are more likely to feel negative paternal rearing style and higher level of family compliance,and less likely to feel positive parental rearing style.

Objective:To systematically evaluate the influencing factors of retinal re-detachment after the first silicone oil removal.Methods:Chinese databases (CNKI, CBM, VIP, Wanfang) and English databases (PubMed, Cochrane, Embase, Web of science) were searched to retrieve the factors affecting the retinal re-detachment after the first pars plana vitrectomy (PPV) combined with silicone oil removal from the inception of the databases to August 20, 2023.The quality of literature was evaluated according to the Newcastle-Ottawa Scale (NOS).The influencing factors related to the retinal re-detachment after the first silicone oil removal were extracted from the literature, and the influencing factors mentioned in <3 literatures were excluded.RevMan5.3 software was used for quantitative and comprehensive analysis.Results:A total of 14 articles were included, including 3 393 eyes, with 498 eyes in the recurrent group, and 2 895 eyes in the non-recurrent group.The results of meta-analysis showed that high myopia (odds ratio [ OR]=1.40, 95% confidence interval [ CI]: 1.08-1.81), giant retinal hole( OR=2.36, 95% CI: 1.63-3.41), vitreous residue ( OR=130.02, 95% CI: 66.03-256.02), intraocular lens status before PPV ( OR=1.86, 95% CI: 1.26-2.75) were the risk factors for retinal re-detachment after silicone oil removal.Rhegmatogenous retinal detachment ( OR=0.68, 95% CI: 0.50-0.92), PPV combined with external scleral compression ( OR=0.63, 95% CI: 0.45-0.88) and fundus laser photocoagulation 2-4 weeks before silicone oil removal ( OR=0.25, 95% CI: 0.13-0.49) were protective factors for retinal detachment after silicone oil removal.The results of sensitivity analysis showed that there was no significant change in the analysis results after changing the analysis model.There was no publication bias among the included studies. Conclusions:High myopia, giant retinal detachment, vitreous residue and intraocular lens status before PPV increased the risk of retinal re-detachment after the first silicone oil removal, Rhegmatogenous retinal detachment, PPV combined with external scleral pressure and fundus laser photocoagulation 2-4 weeks before silicone oil removal may be protective factors.

Objectives:To assess the situation of retained cardiac implantable electronic device(CIED)leads after cardiac transplantation,the associated factors,and their impact on long-term prognosis.Methods:A retrospective analysis was conducted on 1 096 patients who underwent cardiac transplantation at Fuwai Hospital of the Chinese Academy of Medical Sciences from January 1,2005 to January 1,2022.Among them,204 patients(18.6%)received CIED therapy before cardiac transplantation.Two physicians independently reviewed the pre-and post-transplant chest X-rays to determine the presence of retained CIED leads.Logistic multivariate regression analysis was used to assess factors associated with retained CIED leads,and Kaplan-Meier survival curves were plotted to analyze the impact of retained CIED leads on long-term prognosis.Results:Among the 204 patients who received CIED therapy before cardiac transplantation,the highest proportion were those treated with implantable cardioverter defibrillator(ICD)and cardiac resynchronization therapy-defibrillator(CRT-D),accounting for 47.5%(97/204)and 40.7%(83/204),respectively.The mean duration from CIED implantation to cardiac transplantation was(45.1±40.0)months,and 38 patients(18.6%)had retained CIED leads after cardiac transplantation.The results of the logistic multivariate regression analysis showed that the duration from CIED implantation to cardiac transplantation was the only factor associated with retained CIED leads after cardiac transplantation(OR=1.020,95%CI:1.011-1.030,P=0.000).Cumulative all-cause survival rates among patients without CIED implantation(n=892),those without retained CIED leads(n=166),and those with retained CIED leads(n=38)were 88.5%,93.3%and 84.2%,respectively.Kaplan-Meier survival curve analysis showed no significant difference in cumulative all-cause survival among the three groups(log-rank P=0.643).Conclusions:In patients who received CIED implantation before cardiac transplantation,18.6%had retained leads after surgery.The duration from CIED implantation to cardiac transplantation is the only factor associated with lead retained after cardiac transplantation,but retained leads does not affect the outcome post heart transplantation.

Objective:To evaluate the accuracy of respiratory variation in carotid artery blood flow peak velocity (ΔVpeak-CA) combined with tidal volume challenge (TVC) test in predicting fluid responsiveness of patients receiving lung-protective ventilation.Methods:Eighty American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients of either sex, aged 18-80 yr, with a body mass index of 18-30 kg/m 2, undergoing elective open abdominal surgery with general anesthesia, were selected. Lung-protective strategies were used during surgery: FiO 2 40%, tidal volume (V T) 6 ml/kg (ideal body weight), personalized positive end-expiratory pressure. TVC was conducted at 5 min after hemodynamic stabilization following intubation (T 1): V T was adjusted from 6 ml/kg to 8 ml/kg, lasting for 1 min (T 2), and then V T was decreased to 6 ml/kg. Ultrasound was used to measure ΔVpeak before and after TVC test, and ΔVpeak-CA was calculated. Volume expansion was conducted at 5 min after TVC test, and an increase in cardiac index (△CI≥15%) after volume expansion was considered as positive fluid responsiveness. The patients were divided into fluid responsiveness group (R group) and non-responsiveness group (NR group). The receiver operating characteristic curve was plotted and the area under the receiver operating characteristic curve (AUC) was calculated to evaluate the efficiency of ΔVpeak-CA at T 1 (ΔVpeak-CA T 1), ΔVpeak-CA at T 2 (ΔVpeak-CA T 2) and the difference in ΔVpeak-CA between T 1 and T 2 (ΔVpeak-CA T 2-T 1) in predicting fluid responsiveness. Results:Seventy-three patients were finally included in this study, with 45 in R group and 28 in NR group. The AUC of ΔVpeak-CA T 2 in predicting fluid responsiveness was 0.880, with the sensitivity of 0.778 and the specificity of 0.857, and the optimum cut-off value was 14.5%. The AUC of ΔVpeak-CA T 2-T 1 in predicting fluid responsiveness was 0.876, with the sensitivity of 0.667 and the specificity of 0.964, and the optimum cut-off value was 5.5%, and the AUC of ΔVpeak-CA T 1 in predicting fluid responsiveness was only 0.646. Conclusions:ΔVpeak-CA combined with TVC test can accurately predict fluid responsiveness of patients receiving lung-protective ventilation.

Objective To explore the application of plasma 7 microRNA (miR7) testing in the differential diagnosis of very early-stage hepatocellular carcinoma (HCC). Methods This study is a multicenter real-world study. Patients with single hepatic lesion (maximum diameter≤2 cm) who underwent plasma miR7 testing at Zhongshan Hospital, Fudan University, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Anhui Provincial Hospital, and Peking University People’s Hospital between January 2019 and December 2024 were retrospectively enrolled. Patients were divided into very early-stage HCC group and non-HCC group, and the clinical pathological characteristics of the two groups were compared. The value of plasma miR7 levels, alpha-fetoprotein (AFP), and des-gamma-carboxy prothrombin (DCP) in the differential diagnosis of very early-stage HCC was evaluated using receiver operating characteristic (ROC) curves and area under the curve (AUC). In patients with both negative AFP and DCP (AFP＜20 ng/mL, DCP＜40 mAU/mL), the diagnostic value of plasma miR7 for very early-stage HCC was analyzed. Results A total of 64 528 patients from 4 hospitals underwent miR7 testing, and 1 682 were finally included, of which 1 073 were diagnosed with very early-stage HCC and 609 were diagnosed with non-HCC. The positive rate of miR7 in HCC patients was significantly higher than that in non-HCC patients (67.9% vs 24.3%, P＜0.001). ROC curves showed that the AUCs for miR7, AFP, and DCP in distinguishing HCC patients from the non-HCC individuals were 0.718, 0.682, and 0.642, respectively. The sensitivities were 67.85%, 43.71%, and 44.45%, and the specificities were 75.70%, 92.78%, and 83.91%, respectively. The pairwise comparison of AUCs showed that the diagnostic efficacy of plasma miR7 detection was significantly better than that of AFP or DCP (P＜0.05). Although its specificity was slightly lower than AFP and DCP, the sensitivity was significantly higher. Among patients negative for both AFP and DCP, miR7 maintained an AUC of 0.728 for diagnosing very early-stage HCC, with 67.82% sensitivity and 77.73% specificity. Conclusions Plasma miR7 testing is a potential molecular marker with high sensitivity and specificity for the differential diagnosis of small hepatic nodules. In patients with very early-stage HCC lacking effective molecular markers (negative for both AFP and DCP), miR7 can serve as a novel and effective molecular marker to assist diagnosis.

ObjectiveTo understand the seropositivity of neutralizing antibodies (NAb) and low-level NAb against SARS-CoV-2 infection in the community residents, and to explore the impact of COVID-19 vaccination and SARS-CoV-2 infection on the levels of NAb in human serum. MethodsOn the ground of surveillance cohort for acute infectious diseases in community populations in Shanghai, a proportional stratified sampling method was used to enroll the subjects at a 20% proportion for each age group (0‒14, 15‒24, 25‒59, and ≥60 years old). Blood samples collection and serum SARS-CoV-2 NAb concentration testing were conducted from March to April 2023. Low-level NAb were defined as below the 25^th percentile of NAb. ResultsA total of 2 230 participants were included, the positive rate of NAb was 97.58%, and the proportion of low-level NAb was 25.02% (558/2 230). Multivariate logistic regression analysis indicated that age, infection history and vaccination status were correlated with low-level NAb (all P<0.05). Individuals aged 60 years and above had the highest risk of low-level NAb. There was a statistically significant interaction between booster vaccination and one single infection (aOR=0.38, 95%CI: 0.19‒0.77). Compared to individuals without vaccination, among individuals infected with SARS-CoV-2 once, both primary immunization (aOR=0.23, 95%CI: 0.16‒0.35) and booster immunization (aOR=0.12, 95%CI: 0.08‒0.17) significantly reduced the risk of low-level NAb; among individuals without infections, only booster immunization (aOR=0.28, 95%CI: 0.14‒0.52) showed a negative correlation with the risk of low-level NAb. ConclusionsThe population aged 60 and above had the highest risk of low-level NAb. Regardless of infection history, a booster immunization could reduce the risk of low-level NAb. It is recommended that eligible individuals , especially the elderly, should get vaccinated in a timely manner to exert the protective role of NAb.

Objective : To explore the role of lysophosphatidylcholine acyltransferase 3(LPCAT3) in Erastin-induced ferroptosis of acute myeloid leukemia(AML) cells and its related molecular regulatory mechanisms. Methods : Tetrazolium salt(MTS) method was used to detect the sensitivity of different AML cells to the classic ferroptosis inducer Erastin, real time quantitative polymerase chain reaction(qPCR) was used to detect the basal expression level ofLPCAT3mRNA, and the correlation between them was analyzed. Lentivirus-mediatedLPCAT3overexpression AML cell lines(OE group) and negative control lines(NC group) were constructed. After Erastin intervention, MTS, flow cytometry, and micromethods were used to detect cell viability, lipid reactive oxygen species(ROS), and Malondialdehyde(MDA), respectively. qPCR and Western blot were used to detect unfolded protein response(UPR) classic pathway signaling molecules(PERK, ATF4, GRP78, etc.) expression levels. The above ferroptosis-related indicators were detected after combined intervention with the UPR inhibitor 4-phenylbutyric acid(4-PBA), and the regulatory relationship was analyzed. Results : Four different types of AML cells had different sensitivities to ferroptosis, among which K562 cells were relatively insensitive. The IC50of the four types of AML cells to Erastin was negatively correlated with the expression level ofLPCAT3(r=-0.919,P<0.001). After Erastin intervention, the cell viability of K562 cells in the OE group was significantly inhibited by Erastin compared with the NC group(P<0.001), and the levels of lipid ROS and MDA increased(P<0.001). The results of qPCR and Western blot showed that, compared with the NC group, the mRNA and protein expression of UPR classic pathway moleculesPERK,ATF4, andGRP78mRNA and protein increased in the OE group(P<0.01). After inhibiting the UPR pathway by 4-PBA, the viability of K562 cells decreased(P<0.01), and lipid ROS and MDA levels increased(P<0.01) compared with the uninhibited state. Conclusion Overexpression ofLPCAT3can promote ferroptosis in K562 cells, and this process is negatively regulated by the classical UPR pathway PERK/ATF.
