Objective To summarize the clinical efficacy of modified Morrow surgery in the treatment of hypertrophic obstructive cardiomyopathy. Methods A retrospective analysis was conducted on the clinical data of patients with hypertrophic obstructive cardiomyopathy treated with modified Morrow surgery at Zhongshan Hospital Affiliated to Fudan University from 2020 to 2023. Results A total of 318 patients were enrolled, including 156 males and 162 females, with an average age of (55.6±13.1) years. Preoperative echocardiography showed a mean interventricular septal thickness of (18.1±3.8) mm, peak left ventricular outflow tract pressure difference of (86.4±24.9) mm Hg. The surgery time was (162.3±51.0) min, extracorporeal circulation time was (80.9±31.0) min, and aortic occlusion time was (44.8±20.8) min. After the surgery, transesophageal echocardiography showed that the interventricular septal thickness was (11.0±1.8) mm and left ventricular outflow tract peak pressure difference was (9.4±5.1) mm Hg. The incidence rate of postoperative complete left bundle branch block was 45.3%, Ⅲ° atrioventricular block was 3.8%, and postoperative newly developed atrial fibrillation was 3.1%. The postoperative hospital stay was (6.6±4.9) days, and one perioperative death occurred, with a mortality rate of 0.3%. The follow-up time was (10.3±9.4) months, during which the transthoracic echocardiography revealed a ventricular septal thickness of (12.9±2.9) mm and a peak left ventricular outflow tract pressure difference of (13.9±10.0) mm Hg. Conclusion The modified Morrow procedure for the treatment of hypertrophic obstructive cardiomyopathy is safe and effective, with good results in the short and medium term.

OBJECTIVE To investigate the protective effect of 2-dodecyl-6-methoxy-2，5-diene-1，4-cyclohexanedione （DMDD）， an active component from Averrhoa carambola root， on myocardial injury in diabetic mice based on the nuclear receptor coactivator 4/ferritin heavy chain 1/autophagy-related protein 8 （NCOA4/FTH1/ATG8） axis. METHODS The successfully modeled diabetic mice were randomly divided into model group and DMDD low-， medium-， and high-dose （12.5， 25， 50 mg/kg） groups， while an additional non-modeled control group was established， with 6 mice in each group. Each group received the corresponding drug solution or an equal volume of normal saline intragastically once daily for 21 consecutive days. After the administration， the levels of fasting blood glucose （FBG）， serum lactate dehydrogenase （LDH）， and creatine kinase isoenzyme MB （CK-MB） were measured. Myocardial pathological changes， degree of fibrosis， and myocardial cell ultrastructure were observed. Myocardial cell death index and NCOA4 protein positive index were detected. The protein expression levels of NCOA4， FTH1， ATG8， solute carrier family 7 member 11 （SLC7A11）， and glutathione peroxidase 4 （GPX4） in cardiac tissue were measured. RESULTS Compared with model group， each DMDD group showed significant alleviation of cardiac pathological injury and varying degrees of improvement in the myocardial cell ultrastructure. The FBG and serum LDH and CK-MB levels， the myocardial cell death index and NCOA4 protein positive index，the protein expression levels of NCOA4， FTH1， and ATG8 in cardiac tissue were significantly decreased （ P ＜0.001）， while the protein expression levels of SLC7A11 and GPX4 were significantly increased （ P ＜0.001）. CONCLUSIONS DMDD can reduce blood glucose levels， alleviate myocardial histopathological injury， and inhibit cell death in diabetic mice. The mechanism is associated with inhibiting excessive activation of the NCOA4/FTH1/ATG8 axis and reducing ferritinophagy.

BackgroundSchizophrenia， as a common chronic mental disorder， although second-generation antipsychotic drugs have shown significant efficacy in alleviating positive symptoms， the widespread cognitive dysfunction among patients remains a challenge in clinical treatment. Traditional Chinese medicine has unique advantages in the treatment of mental disorders. However， the current clinical research on the combination of Wendan Decoction and antipsychotic drugs for schizophrenia varies in quality， and there is a lack of systematic reviews evaluating its effects on cognitive improvement and safety. ObjectiveTo systematically evaluate the effects of modified Wendan Decoction combined with antipsychotic drugs on schizophrenia symptoms and cognitive improvement， providing evidence-based support for the clinical application of Wendan Decoction. MethodsLiterature searches were conducted in China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP Information， China Biomedical Literature Service System， China Clinical Trial Registry， PubMed， Web of Science， the Cochrane Library， and Embase to collect randomized controlled trials （RCTs） of modified Wendan Decoction combined with antipsychotic drugs for the treatment of schizophrenia. The search period was from the establishment of the databases to March 19， 2026. The quality of the included literature was evaluated using the Cochrane 6.3. Meta-analysis was performed using RevMan 5.3 software. ResultsA total of 11 studies were included， involving 1 130 patients with schizophrenia. Among them， 566 cases were in the study group （receiving modified Wendan Decoction combined with antipsychotic drugs）， and 564 cases were in the control group （receiving antipsychotic drugs only）. Meta-analysis showed that the effective rate of improvement in psychotic symptoms in the study group was higher than that in the control group （RR=1.21，95% CI： 1.15–1.27， P<0.01）. In terms of psychotic symptoms， the Positive and Negative Symptom Scale （PANSS） positive symptom score （MD=-3.69， 95% CI： -5.87–-1.51， P<0.01） and PANSS total score （MD=-9.20， 95% CI： -11.80–-6.59， P<0.01） of the study group were lower than those of the control group. In cognitive function assessments， the Mini-Mental State Examination （MMSE） score （MD=2.51， 95% CI： 1.33–3.68， P<0.01） and the Loewenstein Occupational Therapy Cognitive Assessment （LOTCA） score （MD=11.85， 95% CI： 2.55–21.15， P=0.010） of the study group were higher than those of the control group， and the Wisconsin Card Sorting Test （WCST） score was lower than that of the control group （MD=-9.34， 95% CI： -12.57–-6.11， P<0.01）. The levels of brain-derived neurotrophic factor （BDNF） （SMD=1.34， 95% CI： 0.63–2.05， P<0.01） and nerve growth factor （NGF） （MD=6.94， 95% CI： 4.00–9.89， P<0.01） of the study group were higher than those of the control group. In terms of safety， there was no statistically significant difference in the incidence of adverse reactions between the two groups （RR=0.60， 95% CI： 0.31–1.18， P=0.14）. ConclusionThe modified Wendan Decoction combined with antipsychotic drugs may be more effective than antipsychotic drugs alone in improving positive symptoms and cognitive function in patients with schizophrenia， and it also exerts a favorable neurotrophic regulatory effect. ［Funded by Postgraduate Education Reform and Quality Improvement Project of Henan Province （number， YJS2023AL060）； Key Scientific Research Projects of Higher Education Institutions in Henan Province （number， 24B320018， 25B310004）］

ObjectiveTo explore the clinical application value of CIE 1976 L*a*b*（Lab） color space in the differential diagnosis of early esophageal cancer and non-cancerous lesions. MethodsWe selected the endoscopic images of patients with esophageal lesions confirmed by pathology who underwent white light imaging endoscopy （WLI） and narrow band imaging endoscopy （NBI）. Five regions of interest （ROI） were selected respectively from the mucosa of the lesion area and the mucosa of the surrounding normal area for labeling. The Lab color space parameters were extracted and counted， and the color difference values（ΔE*）were calculated. ResultsA total of 213 eligible patients were included for analysis in the study. In WLI and NBI modes， there were differences in mucosal color between the early esophageal cancer group and the non-cancer group （P<0.05）. Compared with WLI mode， NBI mode could significantly increase the color difference between early esophageal cancer and non-cancerous lesions （P<0.05）. The lightness component value （L* value） of the early esophageal cancer lesion area was lower than that of the non-cancerous lesion area， and this color difference was more significant in the NBI mode （P<0.05）. In WLI mode， there was no significant difference in yellow-blue component value （b* value） between the mucosa of early esophageal cancer and non-cancerous lesions. However， in the NBI mode， the b* value of the mucosa in the non-cancerous lesion area was higher than that in the early esophageal cancer lesion area （P<0.05）. On the red-green axis， the mucosa of the early esophageal cancer and non-cancerous lesions was red in WLI mode and green in NBI mode. There was no significant difference in red-green component value （a* value） between the two groups. ConclusionThere are color differences between early esophageal cancer and non-cancerous lesions under WLI and NBI. The color of early esophageal cancer is darker under WLI， and the color of non-cancerous lesions is yellower under non-magnified NBI mode. Lab color space is helpful to identify early esophageal cancer and non-cancerous lesions.

Objective: To understand the correlation between autistic traits in children with autism spectrum disorder(ASD) and their parental behaviors, so as to provide evidence for improving social behavior in children with ASD. Methods: A total of 62 children aged 4-7 years diagnosed with ASD at Guangdong Provincial Work Injury Rehabilitation Hospital and Guangzhou Yuexiu District Children s Hospital from October 2021 to May 2025 were selected as the ASD group. A random number table method was used to select 62 healthy children of the same age from 3 ordinary kindergartens in Guangzhou as the control (typically developing,TD) group. The Parental Behavior Inventory and Social Responsiveness Scale were used to evaluate parental behaviors and autistic traits in both groups. The t-test and multiple linear regression were used to analyze the relationship between autistic traits in children with ASD and parental behaviors. Results: Compared with the TD group, the ASD group had significantly higher scores in social awareness, social cognition, social communication, social motivation, autistic behavior patterns, and the total score of social responsiveness, with statistically significant differences ( t =35.83, 46.17, 64.36, 41.45, 49.46,101.15, all P <0.01). The score of parental support/participation in the ASD group (24.61±4.30) was lower than that in the TD group (31.27±4.58), while the score of parental hostility/coercion in the ASD group (25.51±2.72) was higher than that in the TD group (12.75±2.72), with statistically significant differences ( t = -8.34, 26.14, both P <0.01). The total score of the Social Responsiveness Scale was negatively correlated with the dimension score of parental support/participation behaviors, and positively correlated with the dimension score of parental hostility/coercion behaviors ( r =-0.60, 0.91,both P <0.05). After adjusting for covariates such as children s age, gender, and primary caregiver, ASD children with exclusive breastfeeding ( β =-8.79) and parental support/participation behaviors ( β = -0.79 ) had a lower risk of autistic traits, while children with parental hostility/coercion behaviors ( β =4.62) had a higher risk of autistic traits (all P <0.05). Conclusion Autistic traits in children with ASD may be related to their parental behaviors and early feeding mode.

AIM:To explore whether microRNA-30a-3p(miR-30a-3p)is involved in the pathogenesis of non-alcoholic fatty liver disease(NAFLD)by regulating autophagy and promoting lipid deposition.METHODS:Eight-week-old C57BL/6 mice were randomly divided into a normal control group and a high-fat diet(HFD)group.Mice in the HFD group were fed with 60％high fat diet for 10 weeks to induce the NAFLD phenotype.Some mice were injected with adeno-virus overexpressing miR-30a-3p via the tail vein and subsequently fed with high-fat diet for 4 weeks.Glucose tolerance and insulin resistance tests were performed at the end of the treatments.In addition,the concentrations of hepatic alanine aminotransferase(ALT),aspartate aminotransferase(AST),triglyceride(TG)and total cholesterol(TC)were mea-sured.Hematoxylin-eosin staining and oil red O staining were conducted to examine morphological changes and lipid depo-sition in the liver tissue.The expression levels of microtubule-associated protein light chain 3(LC3),autophagy-related protein 5(ATG5),beclin-1 and p62 were quantified through Western blot.In addition,NAFLD models were established in AML12 hepatocytes by incubating the cells with palmitic acid and oleic acid(PO).The AML12 cells were transfected with miR-30a-3p shRNA to knock down miR-30a-3p expression.The concentration levels of TG and TC after miR-30a-3p knockdown were measured by the kits.Nile red staining was performed to examine lipid droplet aggregation and dual fluo-rescent recombinant adenovirus Ad-mCherry-GFP-LC3B was transfected into AML12 cells to observe changes in autopha-gic flow.RESULTS:HFD-fed mice exhibited significant insulin resistance and reduced glucose tolerance,significant lip-id deposition in the liver tissue,coupled with increased hepatic ALT,AST,TG and TC levels.The expression levels of au-tophagy-related proteins LC3-Ⅱ,beclin-1,and ATG5 were decreased,while that of p62 was increased(P<0.01).More-over,miR-30a-3p overexpression significantly increased blood glucose and insulin resistance in HFD-fed mice.However,it aggravated lipid droplets deposition in liver tissue and enhanced hepatic TG,TC,AST and ALT levels.Western blot re-vealed that the expression levels of LC3-Ⅱ,beclin-1 and ATG5 were further reduced,while that of p62 was significantly in-creased(P<0.01).In vitro,we observed that the TG and TC levels,as well as lipid accumulation in PO-treated AML12 cells were increased significantly.Similarly,the expression levels of LC3-Ⅱ,beclin-1 and ATG5 were decreased,whereas that of p62 increased in PO-treated AML12 cells(P<0.01).Notably,knockdown of miR-30a-3p resulted in a significant reduction in the TG content in PO-treated AML12 cells and lipid droplet aggregation was significantly suppressed.Further-more,the expression of LC3-Ⅱ,beclin-1 and ATG5 proteins was increased,while that of p62 was decreased significantly and the autophagy flow was improved(P<0.01).CONCLUSION:The miR-30a-3p exacerbates hepatic lipid deposi-tion,inducing severe hepatic steatosis and liver damage,to promote the occurrence and development of NAFLD in mice.Mechanistically,its effects involve inhibition of hepatic autophagy level.

Objective To investigate the risk factors for mortality and bleeding complications in extracorporeal membrane oxygenation(ECMO)treated patients and to evaluate the impact of thrombocytopenia severity on the prognosis of ECMO therapy.Methods A total of 153 patients who received ECMO treatment at Peking University Third Hospital between January 2013 and September 2024 were en-rolled in this study.The patients were divided into death group(n=97)and recovery group(n=56)based on their final outcomes.Additionally,the patients were categorized into bleeding group(n=104)and non-bleeding group(n=49)based on the occurrence of bleeding complications during ECMO.Clinical baseline characteristics and extreme laboratory values during ECMO were compared be-tween groups.Logistic regression was used to analyze the risk factors for mortality and bleeding.The patients were further divided,based on the initial platelet(PLT)values on the day of catheter placement and the lowest platelet count during ECMO,into normal group(PLT≥ 100× 109/L),moderate reduction group[PLT=(50～99)× 109/L],and severe reduction group(PLT＜50× 109/L).Kaplan-Meier analysis was used to compare survival rates among these groups.The patients in the moderate and severe reduction groups were further divided into a platelet transfusion group and a non-transfusion group,and the outcomes and complication rates were com-pared.Results The recovery group had a higher proportion of myocarditis,higher minimum values of PLT,Hb,and Fib,and higher initial PLT values,while the maximum values of lactic dehydrogenase(LDH),total bilirubin(T-Bil),prothrombin time(PT),and procalcitonin(PCT)were lower(all P＜0.05)with significant differences.Logistic regression showed that age and maximum PCT were independent risk factors for mortality(OR=1.025 and 1.015 respectively,all P＜0.05).The bleeding group had longer ECMO dura-tions,more plasma transfusions,lower minimum Hb values,and higher maximum values of WBC,neutrophils(Neu),and APTT(all P＜0.05)with statistical differences.The minimum PLT value,maximum WBC value,and maximum APTT value were independent risk factors for bleeding complications(OR=0.986,1.062,and 1.004 respectively,all P＜0.05).Kaplan-Meier analysis showed that the patients in the severe reduction group had lower survival rates,regardless of whether the grouping was based on initial or minimum platelet counts(all P＜0.05).Platelet transfusion improved the mortality in the severe reduction group(P＜0.05)but had no effect on the moderate reduction group.Conclusion Age and peak value of PCT are the risk factors for mortality in ECMO patients,while mini-mum PLT count,peak value of WBC and APTT are the risk factors for bleeding complications.Early intervention for infection and in-flammation during ECMO may improve the outcome of patients.Severe thrombocytopenia during ECMO therapy increased the risk of mortality,and targeted platelet transfusion may improve the survival of these patients.

Objective To develop a combined model integrating radiomics and 3D deep learning features for improving the predictive efficacy of overall survival in non-small cell lung cancer(NSCLC)patients undergoing radiotherapy,thereby providing a foundation for optimizing individualized radiotherapy strategies.Methods A retrospective analysis was conducted on 522 NSCLC patients from 3 centers.Radiomics features were extracted from the tumor region of interest on radiotherapy planning CT scans,and a 3D-SE-ResNet was constructed to extract deep learning features.Following feature extraction,features were selected via univariate Cox analysis and Lasso-Cox regression,and a combined model was established by fusing the two feature types through principal component analysis.The discriminative ability of the model was evaluated using the concordance index(C-index)and the area under the receiver operating characteristic curve(AUC),while the risk stratification efficacy was verified by Kaplan-Meier survival analysis.Results The predictive performance of deep learning features was significantly superior to that of radiomics features(C-index:0.73 vs 0.65).The combined model achieved the highest predictive performance in the training set,internal test set,and external test set(C-index:0.74,0.69,0.72 respectively),with higher AUC values for predicting 1-year,2-year,and 3-year OS than either single model.Kaplan-Meier analysis showed significant differences in survival between the high-and low-risk groups(Log-rank test,P<0.001),and calibration curves indicated good consistency between predicted and actual survival outcomes.Conclusion The combined model integrating radiomics and 3D deep learning features can accurately predict survival outcomes in NSCLC patients undergoing radiotherapy.The multi-center validation results support its potential application in prognosis stratification for individualized radiotherapy.

Objective:To investigate the effects of oral propranolol on the heart rate and blood glucose levels in children with hemangiomas receiving hospital care.Methods:A total of 259 children [77 males and 182 females, aged (125.2±85.4) days, weighted (6.3±1.6) kg], who were treated with oral propranolol for the first time under hospital care from January 2013 to August 2021, were retrospectively analyzed. After fasting, the patients administered the same dose of propranolol once daily (0.5-2.5 mg/kg). Fasting blood glucose and heart rate were measured in all children before propranolol administration and after 2 h. Heart rate was measured at 1, 3 and 6 h after propranolol administration for three consecutive days. Adverse reactions were observed and recorded.Results:Within three days of oral propranolol administration, the heart rates at 1, 3 and 6 h after propranolol administration were lower than those before propranolol administration (all P<0.001). Within three days after taking propranolol and 2 h after taking propranolol daily, blood glucose levels reduced in all children (all P<0.001). During the hospitalization period, the incidence of adverse reactions was 5.4% (14/259), including lesion ulcers in four cases, upper respiratory tract infection with fever in four, reduced eating in two, nausea and vomiting in one, lethargy in one, sinus tachycardia in one, and hyperkalemia in one. No serious adverse reactions were life-threatening. Conclusion:After oral administration of propranolol, the heart rate and blood sugar of the children decrease to different degrees compared with those before propranolol administration.
