Objective To explore the advantages and disadvantages of da Vinci robotic-assisted thoracoscopic resection of pediatric posterior mediastinal tumors compared to traditional thoracoscopic surgery.Methods A total of 79 pediatric patients who underwent posterior mediastinal tumor resection at Union Hospital,Tongji Medical College,Huazhong University of Sci-ence and Technology,between January 2018 and October 2021 were included.Among them,47 patients underwent da Vinci ro-botic-assisted thoracoscopic surgery(Group A),and 32 patients underwent traditional thoracoscopic surgery(Group B).The pa-tients'age,gender,weight,tumor type,size,surgical time,intraoperative and postoperative complications,and other factors were compared and analyzed.Results There were 44 male and 35 female patients,with an average age of 4.5 years[(4.7±2.4)vs.(4.4±1.8),P=0.19]and an average weight of 21.7 kg[(23.6±7.5)vs.(20.9±6.1),P=0.10].Tumor sizes were(5.2±3.1)cm vs.(4.5±2.3)cm(P=0.07).All surgeries were completed safely with no intraoperative deaths.Pathological re-sults showed 25 cases of ganglioneuroma,19 cases of ganglioneuroblastoma,16 cases of neuroblastoma,10 cases of lymphangio-ma,8 cases of foregut cyst,and 1 case of lipoblastoma.One patient required conversion to thoracotomy due to intraoperative bleeding.The average anesthesia time[(127±25)vs.(124±30)min,P=0.42]and the operative time[(84±17)vs.(102±27)min,P=0.02)were significantly different.Estimated intraoperative blood loss[(14.6±4.4)vs.(15.4±5.3)mL,P=0.38]and the chest drainage time[(3.7±2.5)vs.(4.1±3.0)days,P=0.09]varied between groups.The average lengths of hospital stay were different[(7.2±1.9)vs.(7.4±2.3)days,P=0.40].Postoperative complications included 1 case of chylo-thorax,3 cases of pneumothorax,and 1 case of Horner's syndrome in Group A.There were 1 case of hemothorax,4 cases of pneumothorax,and 1 case of Horner's syndrome in Group B.Patients with ganglioneuroblastoma and neuroblastoma received postoperative chemotherapy.Follow-up for 2 to 5 years showed that all children recovered well,with no recurrence.Conclusion Both da Vinci robotic-assisted surgery and traditional thoracoscopic surgery are safe and feasible for pediatric mediastinal tumor surgery.The optimized instruments of the da Vinci robotic surgical system offer advantages in surgeries involving larger tumors or complex anatomical structures.

With the rapid development of generative artificial intelligence(GAI)technologies,their widespread application in academic research and writing is continuously expanding the boundaries of sci-entific inquiry.However,this trend has also raised a series of ethical and regulatory challenges,inclu-ding issues related to authorship,content authenticity,citation accuracy,and accountability.In light of the growing involvement of AI in generating academic content,establishing an open,controllable,and trustworthy ethical governance framework has become a key task for safeguarding research integrity and maintaining trust within the academic community.This expert consensus outlines ethical requirements across key stages of AI-assisted academic writing-including topic selection,data management,citation practices,and authorship attribution.It aims to clarify the boundaries and ethical obligations surrounding AI use in academic writing,ensuring that technological tools enhance efficiency without compromising in-tegrity.The goal is to provide guidance and institutional support for building a responsible and sustainable research ecosystem.

Objective To analyze the risk factors for increased drainage volume after open transforaminal lumbar interbody fusion(TLIF),and to establish a predictive model and then validate it.Methods The clinical data of 680 patients who underwent open TLIF at the General Hospital of Northern Theater Command from January 2016 to December 2019 were collected and the patients were randomly divided into the training group(n=476)and the validation group(n=204).Taking the predictive factors screened out by LASSO regression analysis as independent variables,a multivariate Logistic regression predictive model was constructed.The model was internally validated through the receiver operating characteristic(ROC)curve,Hosmer-Lemeshow goodness-of-fit test,and calibration curve,and its clinical utility was assessed via decision curve analysis(DCA).Results LASSO regression analysis screened out four predictive variables:age,number of surgical segments,operative duration,and intraoperative blood loss.The multivariate Logistic regression predictive model demonstrated that age≥60 years,number of surgical segments≥4,operative duration≥2 hours,and intraoperative blood loss≥200 mL were independent influencing factors for the increased postoperative drainage volume in patients undergoing TLIF(P<0.05).ROC curve analysis revealed an area under the curve(AUC)of 0.816(95%CI:0.798 to 0.867)in the training group and 0.783(95%CI:0.685 to 0.823)in the validation group,indicating that the predictive model had good discriminatory ability.Additionally,the Hosmer-Lemeshow goodness-of-fit test and calibration curve indicated that the predictive model had a good degree of fit,and the predicted probability was basically consistent with the actual probability,demonstrating a good calibration.The DCA results confirmed that this predictive model could be applied in clinical practice.Conclusion The risk factors for increased drainage volume after open TLIF include age,number of surgical segments,operative duration,and intraoperative blood loss.The predictive model established based on these factors demonstrates good performance,and it can be applied in clinical guidance for the selection of drainage tube removal time after TLIF.

Objective To study the distribution of intestinal flora in osteoporosis patients with spleen deficiency syndrome.Methods According to the diagnostic criteria of osteoporosis of the World Health Organization(WHO)and the syndrome differentiation criteria of spleen deficiency syndrome in traditional Chinese medicine(TCM),26 healthy attenders with normal bone mass while without spleen deficiency were selected from the population visited Shunde Hospital of Guangzhou University of Chinese Medicine from January 2022 to September 2023 as the normal bone mass group,23 patients with bone mass reduction and spleen deficiency syndrome served as decreased bone mass with spleen deficiency group(shorten as DBM-SD group),and 69 patients with osteoporosis and spleen deficiency syndrome diagnosis were osteoporosis with spleen deficiency group(shorten as OS-SD group).A total of 118 attenders were enrolled in the analysis.The gender,age,body height,body weight,and body mass index(BMI)of the subjects were collected.The bone mineral density(BMD)and serum levels of calcium and alkaline phosphatase(ALP)of the subjects were measured.Stools were collected for the detection of the sequence of the 16SrRNA V3-V4 region,and the sequencing results were given species annotation,and then the correlation of community difference between groups and BMD with the intestinal flora was explored.Results(1)There were significant differences in the relative abundance of intestinal flora between the normal bone mass group and the OS-SD group:differences were shown in Firmicutes(t=2.490,P=0.016),Verrucomicrobia(t=2.180,P=0.003)and Fusobacteria(t=2.270,P=0.026),in Acidobacteria(t=3.003,P=0.003),Lactobacillus(t=3.150,P=0.002)and Bifidobacterium(t=7.248,P=0.001),and in Fecalibacterium(t=2.810,P=0.006)and Rothia(t=2.810,P=0.006).(2)There were significant differences in the relative abundance of intestinal flora between the normal bone mass group and the DBM-SD group:differences were shown in Lactobacillus(t=3.841,P=0.001)and Bifidobacterium(t=2.712,P=0.01),and in Faecalibacterium(t=2.466,P=0.017).(3)There were significant differences in the relative abundance of intestinal flora between the OS-SD group and DBM-SD group:differences were shown in Firmicutes(t=2.321,P=0.025),Bacteroidetes(t=0.393,P=0.020)and Verrucomicrobia(t=3.109,P=0.031).(4)The results of logistic regression analysis showed that in the OS-SD group,lumbar BMD was negatively correlated with Lactobacillus(R=0.355,P=0.003)and Bifidobacterium(R=0.366,P=0.002),positively correlated with Bacteroides(R=0.245,P=0.042),and was negatively correlated Rothia(R=0.330,P=0.006).Conclusion Some bacteria in the intestinal flora are related to the BMD of osteoporosis patients with spleen deficiency syndrome,and significant difference exists in the distribution of intestinal flora between the normal bone mass group and the OS-SD group.The results will provide a theoretical basis for the prevention and treatment of osteoporosis patients with spleen deficiency syndrome from the perspective of the changes of intestinal flora.
