Objective: To analyze the association of mother-child interaction and screen exposure of preschool children with psychological and behavioural problems, so as to provide guidance for promoting the psychological development of preschool children. Methods: From November to December 2024, a convenience cluster sampling method was used to survey 2 977 mothers of preschool children in Daguan and Yingjiang districts of Anqing City. The Chinese Parent-Child Interaction Scale (CPCIS) was applied to evaluate the quality of mother-child interaction, and the Conners Parent Symptom Questionnaire (PSQ) was used to assess the psychological and behavioral problems of preschool children. Binary Logistic regression was applied to analyze the association of mother-child interaction, screen exposure and their combined effect on psychological and behavioral problems among preschool children. Results: The detection rate of psychological and behavioral problems among preschool children was 13.9%. Binary Logistic regression results showed that low scores of mother-child interaction ( OR=2.31, 95%CI =1.72-3.11) and high screen exposure ( OR= 1.52 , 95%CI =1.23-1.88) were higher risks for psychological and behavioral problems in preschool children; the results of the combined effect showed that preschool children in low scores of mother-child interaction and low screen exposure group ( OR=2.18, 95%CI =1.46-3.28), low scores of mother-child interaction and high screen exposure group ( OR=3.13, 95%CI =2.10- 4.65 ) had significantly higher risks of abnormal detection in psychological and behavioral problems, compared to those in the high scores of mother-child interaction and low screen exposure group respectively (all P <0.05). Conclusions Both screen exposure and mother- child interaction are associated with psychological and behavioral problems in preschool children. High quality mother-child interaction can relieve the adverse effects of screen exposure on preschool children s psychological and behavioral development.

Objective:To analyze the application efficacy of employing high-density porous polyethylene （Su-por） in combination with temporoparietal fascial flaps via a minimally invasive scalp incision in auricular reconstruction. Methods:This study carried out a retrospective analysis of 50 patients （50 ears in total） who underwentprimary auricular reconstruction with a Su-por scaffold in our hospital from June 2022 to January 2024. All patients underwent primary auricular reconstruction using a minimally invasive scalp incision with high-density porous polyethylene （Su-por） and temporoparietal fascial flaps. The postoperative treatment effects and complications were statistically analyzed. Results:The reconstructed ears of all patients survived. After 6 months of follow-up, the scar hyperplasia of the scalp minimally invasive incision was not obvious in any patient, and no significant hair loss was observed. The reconstructed auricle of 48 patients had a realistic shape and strong three-dimensional sense. With the extension of follow-up time, the three-dimensional structure of the auricle became clearer, and patient satisfaction increased. Among the remaining two patients, one case of flap necrosis survived after skin grafting and dressing changes. One patient had scar hyperplasia at the incision of the reconstructed ear due to a scar-prone constitution, and the shape of the auricle was not ideal, but the scar hyperplasia at the scalp incision was not obvious. Conclusion:One-stage ear reconstruction with high-density porous polyethylene （Su-por） combined with superficial temporal fascia flap through a minimally invasive scalp incision can better show the fine structure of the reconstructed ear. The minimally invasive scalp incision can effectively reduce the occurrence of scar hyperplasia and postoperative alopecia at the scalp incision.

Metformin has been demonstrated to attenuate hyperglycaemia by modulating the gut microbiota. However, the mechanisms through which the microbiome mediates metformin monotherapy failure (MMF) are unclear. Herein, in a prospective clinical cohort study of newly diagnosed type 2 diabetes mellitus (T2DM) patients treated with metformin monotherapy, metagenomic sequencing of faecal samples revealed that Phocaeicola vulgatus abundance was approximately 12 times higher in nonresponders than in responders. P. vulgatus rapidly hydrolysed taurine-conjugated bile acids, leading to ceramide accumulation and reversing the improvements in glucose intolerance conferred by metformin in high-fat diet-fed mice. Interestingly, C22:0 ceramide bound to mitochondrial fission factor to induce mitochondrial fragmentation and impair hepatic oxidative phosphorylation in P. vulgatus-colonized hyperglycaemic mice, which could be exacerbated by metformin. This work suggests that metformin may be unsuitable for P. vulgatus-rich T2DM patients and that clinicians should be aware of metformin toxicity to mitochondria. Suppressing P. vulgatus growth with cefaclor or improving mitochondrial function using adenosylcobalamin may represent simple, safe, effective therapeutic strategies for addressing MMF.

Objective:To explore the predictive value of pulmonary effective arterial elastance (Ea) in patients with heart failure (HF).Methods:This is a retrospective cohort study, which retrospectively included 284 patients with HF who underwent right heart catheterization at Heart Failure Center in Fuwai Hospital between September 2013 and February 2022. Data regarding baseline clinical characteristics, hemodynamic profiles, and prognosis were collected. Ea was calculated as mean pulmonary arterial pressure/stroke volume. Patients were divided into Ea<0.555 group and Ea≥0.555 group according to the median value of Ea (0.555 mmHg/ml, 1 mmHg=0.133 kPa). The primary outcome was the primary clinical event, set as the first occurrence of a series of composite events, including all-cause death, heart transplantation, left ventricular assist device implantation, and HF rehospitalization. Event-free survival was defined as the absence of primary clinical events. Spearman correlation analysis was used to calculate the correlation coefficient between Ea and parameters reflective of right heart function. The Kaplan-Meier analysis was used to compare the different groups for the estimation of outcomes with the log-rank test. We used Cox proportional-hazards regression models to estimate hazard ratios ( HR) for primary clinical event. Subgroup analysis was performed based on the age, gender, New York Heart Association (NYHA) functional class, left ventricular ejection fraction, presence of pulmonary hypertension, and serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) values. We used receiver operating characteristic (ROC) curve to calculate the area under the curve ( AUC) of Ea for predicting event-free survival in patients with HF. Results:The median age was 51 years, and 206 (72.5%) patients were male. Ea and pulmonary vascular resistance (PVR) were significantly correlated ( r=0.698, P<0.001). The correlation between Ea and pulmonary arterial elastance (PAC) were even more significant ( r=-0.888, P<0.001). Compared with Ea<0.555 group, Ea≥0.555 group presented with higher serum NT-proBNP values (4 443 (1 792, 8 554) ng/L vs. 1 721 (480, 4 528)ng/L, P<0.001), higher PVR (3.4 (2.5, 4.7) Wood vs. 1.4 (0.9, 2.2) Wood, P<0.001), lower cardiac output (3.0 (2.3, 3.9) L/min vs. 4.3 (3.8, 4.9) L/min, P<0.001), and lower PAC (1.6 (1.3, 2.0) ml/mmHg vs. 4.0 (3.0, 6.0) ml/mmHg, P<0.001). The median follow-up time was 392 (166, 811) days. The Kaplan-Meier survival curve demonstrated a lower event-free survival rate in the Ea≥0.555 group compared to the Ea<0.555 group ( Plog-rank<0.001). After multivariate adjustment, Ea ( HR=1.734, P<0.001) remained significantly associated with the primary outcome. Subgroup analysis indicated that Ea was associated with the primary outcome across all subgroups. The AUC was 0.724 ( P<0.001) for Ea to predict event-free survival calculated from ROC analysis. Conclusions:Ea is closely related to parameters reflective of right ventricular afterload. Increased Ea is an independent predictor of adverse outcomes in patients with HF.

Objective To explore the value of curvature value of liver surface nodularity(LSN)based on MRI in evaluating liver function in patients with liver cirrhosis.Methods A retrospective analysis was made on the patients who underwent upper abdomen MR examination at 3.0T.The normal liver function patients and cirrhosis patients were enrolled in the study and then the Child-Pugh score of the patients were calculated.The patients were divided into three groups:normal liver group,compensated cirrhosis group and decompensated cirrhosis group.The water phase imaging of 3D modified Dixon fast field echo(mDixon-FFE)sequence was copied in DICOM format.ITK software was used to manually draw the full-thickness liver edge by two observers.The curvature value of LSN was obtained by using matlab self compiled code for follow up analysis.Kruskal-Wallis H test was used to compare the curvature value between the groups.The receiver operating characteristic(ROC)curve was drawn and the area under the curve(AUC)was obtained.Spearman test was used for the correlation analysis.Results The curvature values of LSN among the normal liver,compensated cirrhosis and decompensated cirrhosis groups gradually increased(P<0.05).Comparing normal liver with compensated cirrhosis,the AUC of diagnosing compensated cirrhosis was 0.84,with the sensitivity of 72.7%and the specificity of 89.3%.Comparing compensated cirrhosis with decompensated cirrhosis,the AUC of diagnosing decompensated cirrhosis was 0.91,with the sensitivity of 80%and the specificity of 90.9%.There was a moderate positive correlation between the curvature value of LSN and liver function score in patients with cirrhosis(r=0.63,P=0.002).Conclusion The curvature value of LSN based on MRI can be used for preliminary evaluation of liver function of liver cirrhosis,with the AUC more than 0.80 and higher sensitivity and specificity.

ObjectiveTo investigate the effects of berbamine hydrochloride on sorafenib resistance in hepatocellular carcinoma cells and the underlying mechanisms. MethodThe sorafenib-resistant cell line SMMC-7721/S was selected by the concentration increment method starting at 1.25 μmol·L^-1 sorafenib. Both SMMC-7721 and SMMC-7721/S cells were treated with 0， 2.5， 5， 10， 15， 20 μmol·L^-1 sorafenib， and the cell counting kit-8 （CCK-8） assay was employed to determine the half maximal inhibitory concentration （IC₅₀） and calculate the resistance index （RI）. Western blot was conducted to compare the expression of proteins involved in autophagy and phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway between SMMC-7721 and SMMC-7721/S cells. Furthermore， SMMC-7721/S cells were treated with 5 μmol·L^-1 berbamine hydrochloride alone or in combination with 2.5， 5， 10 μmol·L^-1 sorafenib， and the cell growth was assessed by the CCK-8 assay. In addition， SMMC-7721 and SMMC-7721/S cells were treated with 5 μmol·L^-1 berbamine hydrochloride alone or in combination with 5 μmol·L^-1 sorafenib， and the cell proliferation was examined by the colony formation assay. The immunofluorescence assays with Microtubule-associated protein 1 light chain 3 （LC3） and LysoTracker as probes were employed to assess the lysosomal acidification in SMMC-7721 cells treated with 5 μmol·L^-1 berbamine hydrochloride or 0.1 μmol·L^-1 autophagy inhibitor bafilomycin A1 （Baf）. Further， the expression of proteins involved in autophagy and PI3K/Akt/mTOR signaling pathway was determined by Western blot and compared between groups. ResultSorafenib showed the IC₅₀ of 9.56 mol·L^-1 （P<0.01） and 7.99 mol·L^-1 for SMMC-7721/S and SMMC-7721 cells， respectively， at 24 h. The resistance index （RI） of SMMC-7721/S for sorafenib was 1.20 （P<0.01）， which indicated mild resistance. Compared with SMMC-7721 cells， SMMC-7721/S cells exhibited up-regulated expression of p-mTOR， p-Akt， and LC3Ⅱ， down-regulated expression of p62 protein （P<0.01）， and unchanged Akt protein level. CCK-8 and colony formation assays demonstrated that the combination of berbamine hydrochloride and sorafenib exhibited a synergistic effect （Q>1.15）， with berbamine hydrochloride partially reversing the resistance of liver cancer cells to sorafenib. The immunofluorescence detection of LC3 revealed that berbamine hydrochloride and Baf significantly increased LC3 in SMMC-7721 cells. The detection with LysoTracker as the probe showed that berbamine hydrochloride inhibited the acidity of lysosomes in SMMC-7721 cells （P<0.01）， indicating the suppression of autophagy. Berbamine hydrochloride further enhanced the downregulation of p-mTOR and p-Akt protein levels and did not change the Akt protein level in SMMC-7721 cells exposed to sorafenib. Berbamine hydrochloride inhibited the increase in p-mTOR expression， down-regulated the p-Akt protein level， and did not change the total Akt protein level in the SMMC-7721/S cells exposed to sorafenib. ConclusionBerbamine hydrochloride can ameliorate the resistance of liver cancer cells to sorafenib by inhibiting cellular autophagy and the PI3K/Akt/mTOR signaling pathway.

Objective: To analyze the associations among body mass index (BMI), learning screen/gaming screen exposure and executive function in preschool children in Anhui Province, so as to provide a basis for promoting the development of executive function in preschool children. Methods: In June 2022, a stratified cluster sampling and convenience sampling methods were used to survey 3 534 mothers of preschool children in Wuhu City, Luan City, and Fuyang City, Anhui Province. The Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) was used to assess the preschool childrens executive function abnormalities. Binary Logistic regression was conducted to examine the relationships among BMI, learning screen/gaming screen exposure, and their combined effects on executive function abnormalities. Results: The detection rate of abnormal executive function in preschool children was 9.65%. Logistic regression analysis showed that after adjusting for the confounding factors such as pregnancyinduced hypertension, primary caregivers, family per capita monthly income and family structure, the risk of abnormal executive function of children in overweight/obesity group and high learning screen/gaming screen exposure group increased significantly (overweight/obesity:OR=1.78, 95%CI=1.31-2.42, learning screen exposure:OR=1.48, 95%CI=1.18-1.86, gaming screen exposure:OR=1.50, 95%CI=1.18-1.91,P<0.05). Compared with children with normal BMI and low learning screen/gaming screen screen exposure, those with both overweight/obesity and high learning screen/gaming screen exposure had a significantly greater risk of executive function abnormalities (OR=2.07, 95%CI=1.29-3.31; OR=2.42, 95%CI=1.59-3.68,P<0.05). Conclusions Overweight/obesity and high learning screen/gaming screen exposure are important risk factors for executive function abnormalities in preschool children. Therefore, actively guiding preschool children to develop healthy life habits to promote the normal development of their executive functions is essential.

Background::Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods::We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018).Results::Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted β = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted β = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring’s overall crystallized intelligence. Conclusions::Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.
