Objective To investigate the effect of obstructive sleep apnea(OSA)on behavioral problems in children and the association between them.Methods A simple random sampling method was used to select 100 children aged 4 to 12 years for the case group.All of them were diagnosed with OSA through overnight polysomnography at the Sleep Medicine Center,West China Fourth Hospital,Sichuan University between October 2022 and October 2023.An additional 100 children without snoring symptoms and clinically evaluated and confirmed as not having OSA were enrolled as the control group.General demographic data of the participants were collected.The Caregiver Report Form of the Achenbach Child Behavior Checklist(CBCL)was used for behavioral problem assessment,and polysomnography data were collected.The chi-square/t test was used to analyze the inter-group differences in general data,the total score of behavioral problems,and scores for each dimension.Linear regression was performed to analyze the relationship between OSA and the total score for children's behavioral problems and those for the different dimensions.Logistic regression was applied to analyze the relationship between the obstructive apnoea-hypopnea index(OAHI)and behavioral problems in children with OSA.A logistic regression model integrating the OAHI×sex interaction term was constructed to evaluate the moderating effect of sex on the association between OAHI and behavioral problems.Results No significant differences were observed in general demographic data between the case and control groups.The total score for behavioral problems and those for each dimension were higher in the case group than those in the control group,with the total score of the case group being 24.60±1.55 and that of the control group being 8.85±0.75(P<0.001).The results of the linear regression analysis showed a positive association between OSA and both the total score for behavioral problems(b=16.01;95%CI,12.56-19.47)and those for each dimension.The results of the logistic regression analysis showed that,after adjusting for covariates,OAHI was a risk factor for behavioral problems in children with OSA(odds ratio[OR]=1.17;95%CI,1.04-1.31).After stratification by sex and adjustment for covariates,the OR value of the effect of OAHI on behavioral problems was slightly higher in female participants(1.57)than that in male participants(1.21).The interaction effect analysis showed that sex moderated the association between OAHI and behavioral problems(OR=1.64;95%CI,1.02-2.64;P=0.04).Conclusion Children with OSA are prone to developing behavioral problems.OAHI is a risk factor for behavioral problems in children with OSA,with a potentially greater effect observed in girls.

Objective:To explore the efficacy and prognosis of hepatectomy via Laennec membrane approach in patients with hepatocellular carcinoma (HCC).Methods:The data of 98 patients with HCC who underwent hepatectomy in the First Affiliated Hospital of Soochow University from January 2016 to December 2022 were retrospectively analyzed, including 76 males and 22 females, aged 61.0 (55.0, 66.0) years. Forty-eight patients treated with Laennec membrane approach hepatectomy were included in the study group and 50 patients treated with traditional approach hepatectomy were included in the control group. The age, gender, combined hypertension and diabetes, aspartate transaminase, alanine transaminase, albumin, total bilirubin, prealbumin, platelet, alpha-fetoprotein, carbohydrate antigen 19-9 and carbohydrate antigen 125 were compared between the two groups. The surgical bleeding, operation time and complications (abdominal bleeding, bile leakage, poor incision healing, etc.) were compared between the two groups. The prognosis of the two groups was compared.Results:There were no significant differences in gender, age, underlying diseases, preoperative biochemical and tumor serological indexes between the two groups (all P>0.05). The operation time of the study group was 180.0 (141.3, 227.3) min, which was lower than that of the control group 221.5 (187.5, 256.3) min ( Z=-0.41, P=0.002). The intraoperative blood loss in the study group was 295.0 (127.5, 350.0) ml, which was lower than that in the control group 300.0 (200.0, 500.0) ml, and the difference was statistically significant ( Z=-1.97, P=0.003). The levels of aspartate transaminase and alanine transaminase 1 week after surgery in the study group were 33.4 (24.0, 43.8) U/L and 64.5 (38.3, 119.1) U/L, respectively, which were lower than those in the control group 41.3 (29.7, 63.0) U/L and 102.8 (50.1, 140.7) U/L, the differences were statistically significant ( Z=-2.09, -2.38, P=0.035, 0.028). Postoperative complications occurred in 8 cases (16.7%) in the study group and 10 cases (20.0%) in the control group, with no significant difference between the two groups ( χ2=0.18, P=0.670). The median overall survival was 16 months in the study group and 18 months in the control group, respectively. There was no significant difference in cumulative survival between the two groups ( χ2=1.41, P=0.130). Conclusion:Laennec membrane approach hepatectomy can not only shorten the operation time and reduce the amount of blood loss, but also promote the recovery of liver function.

Cardiovascular diseases have become the leading cause of mortality worldwide.The gut microbiota and its metabolites play an important role in the occurrence and development of cardiovascular diseases,and an imbalance of gut microbiota and its metabolites can promote the progression of cardiovascular diseases.Phenylacetylglutamine is a phenyl-alanine metabolite of intestinal flora.More and more studies have shown that phenylacetylglutamine is an independent risk factor of cardiovascular diseases and a potential biomarker of cardiovascular diseases.It is involved in the pathogenesis of cardiovascular diseases,such as arrhythmia,heart failure,atherosclerosis,etc.Therefore,interventions targeting pheny-lacetylglutamine are expected to become a new strategy for treating cardiovascular diseases.This review focuses on the role of phenylacetylglutamine in the occurrence and development of several common cardiovascular diseases.

Objective To develop and validate a nomogram prediction model for residual stone risk after flexible ureteroscopic lithotripsy(FURL)in patients with 2-3 cm renal calculi,so as to provide reference for treatment options.Methods Clinical data of 342 patients with renal calculi measuring 2-3 cm undergoing FURL in our hospital during Jun.2017 and Apr.2024 were retrospectively collected.At a 3∶1 randomization ratio,patients were allocated to the training cohort(n=257)and validation cohort(n=85).Patients in the training cohort were stratified into two subgroups based on postoperative stone-free status:residual stone group(n=63)and stone-free group(n=194).Logistic regression analysis was employed to identify factors influencing stone retention and construct the nomogram prediction model.Bootstrapped resampling was applied to validate the model internally,model performance was assessed with calibration curves,Hosmer-Lemeshow test was used to test the degree of fitting,receiver operating characteristic(ROC)curve was plotted to evaluate the predictive accuracy,and decision curve analysis was used to determine the clinical net benefit.The model's generalization capability was evaluated with 10-fold cross-validation of the training set.Results Multivariate logistic regression revealed that stone size,CT value,lower calyx stones,multiple stones,renal infundibulum length(RIL),and renal infundibulum width(RIW)were independent predictors of residual stones(P＜0.05).The nomogram based on the above mentioned parameters demonstrated excellent discrimination,with Bootstrap-validated concordance indices of 0.876(training cohort)and 0.948(validation cohort).Hosmer-Lemeshow tests showed good calibration in both cohorts(P＞0.05).ROC analysis yielded the area under the curve(AUC)of 0.876 and 0.948 for the training and validation cohorts,respectively.The optimal cutoff value was 0.253,with corresponding sensitivity of 84.13％,specificity of 78.35％,and total score of nomogram of 143.The decision curve analysis showed when the threshold probability of the training cohort and verification cohort was 0-0.81 and 0-0.97,respectively,the nomogram could obtain good clinical net benefit in predicting the risk of residual stones.The average accuracy of 10-fold cross-validation was 0.814,and the average AUC was 0.865.Conclusion The nomogram model effectively predicts residual stone risk following FURL for 2-3 cm renal calculi.It is suggested that patients with a total score of ≤143 may consider undergoing FURL.

Objective:To explore the efficacy and prognosis of hepatectomy via Laennec membrane approach in patients with hepatocellular carcinoma (HCC).Methods:The data of 98 patients with HCC who underwent hepatectomy in the First Affiliated Hospital of Soochow University from January 2016 to December 2022 were retrospectively analyzed, including 76 males and 22 females, aged 61.0 (55.0, 66.0) years. Forty-eight patients treated with Laennec membrane approach hepatectomy were included in the study group and 50 patients treated with traditional approach hepatectomy were included in the control group. The age, gender, combined hypertension and diabetes, aspartate transaminase, alanine transaminase, albumin, total bilirubin, prealbumin, platelet, alpha-fetoprotein, carbohydrate antigen 19-9 and carbohydrate antigen 125 were compared between the two groups. The surgical bleeding, operation time and complications (abdominal bleeding, bile leakage, poor incision healing, etc.) were compared between the two groups. The prognosis of the two groups was compared.Results:There were no significant differences in gender, age, underlying diseases, preoperative biochemical and tumor serological indexes between the two groups (all P>0.05). The operation time of the study group was 180.0 (141.3, 227.3) min, which was lower than that of the control group 221.5 (187.5, 256.3) min ( Z=-0.41, P=0.002). The intraoperative blood loss in the study group was 295.0 (127.5, 350.0) ml, which was lower than that in the control group 300.0 (200.0, 500.0) ml, and the difference was statistically significant ( Z=-1.97, P=0.003). The levels of aspartate transaminase and alanine transaminase 1 week after surgery in the study group were 33.4 (24.0, 43.8) U/L and 64.5 (38.3, 119.1) U/L, respectively, which were lower than those in the control group 41.3 (29.7, 63.0) U/L and 102.8 (50.1, 140.7) U/L, the differences were statistically significant ( Z=-2.09, -2.38, P=0.035, 0.028). Postoperative complications occurred in 8 cases (16.7%) in the study group and 10 cases (20.0%) in the control group, with no significant difference between the two groups ( χ2=0.18, P=0.670). The median overall survival was 16 months in the study group and 18 months in the control group, respectively. There was no significant difference in cumulative survival between the two groups ( χ2=1.41, P=0.130). Conclusion:Laennec membrane approach hepatectomy can not only shorten the operation time and reduce the amount of blood loss, but also promote the recovery of liver function.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
