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.

As the first defense of respiratory system,airway epi-thelial cells(AECs)play an important role in separating the re-spiratory internal and external environment.They are essential for the natural immune function.Small airway lesions are an im-portant early pathology of chronic obstructive pulmonary disease(COPD),when AECs are exposed to harmful particles or gases for a long time,the epithelial barrier is damaged,and the signa-ling pathways which involved in differentiation,repair,and in-flammatory are disordered,resulting in epithelial cell cycle stag-nation and accelerated aging.A number of studies have sugges-ted that AECs of COPD patients express high levels of aging markers,suggesting that senescence of AECs is closely related to COPD.This review discusses the potential mechanisms of AECs senescence in COPD,the impact of AECs senescence on the de-velopment and severity of the disease,and highlights potential targets for modulating cellular senescence in airway epithelium as a therapeutic approach in COPD.

Objective To clarify the effect of preoperative oral carbohydrate on overweight or obese patients undergoing laparoscopic hysterectomy in Trendelenburg position.Methods A total of 72 overweight or obese patients who underwent laparoscopic hysterectomy in Trendelenburg position at Yancheng Third People's Hospital from September 2022 to August 2024 were selected,and randomly divided into the control group and the observation group,with 36 cases in each group.The control group received routine restriction of fasting and fluid starting from 22:00 on the day before surgery,while the observation group was given an additional 300 mL of carbohydrate orally 2 hours before anesthesia on the basis of the control group.The preoperative ultrasound results of gastric antrum,Perlas classification,full stomach status,visual analogue scale(VAS)scores for thirst and hunger,awakening time,tracheal extubation time,intraoperative hypothermia,gastro-intestinal function recovery time,and adverse reactions were compared between the two groups.Results Before anesthesia,there was no statistically significant difference in the cross-sectional area of the gastric antrum(CSA)in the right lateral position,gastric volume(GV),or the ratio of gastric volume to body weight(GV/W)between the two groups(P>0.05).There was also no statistically significant difference in the Perlas classification of gastric antrum ultrasound or the incidence of full stomach between the two groups(P>0.05).Immediately before anesthesia,the VAS scores for thirst and hunger in the observation group were significantly lower than those in the control group(P<0.05).The awakening time,tracheal extubation time,and incidence of intraoperative hypothermia in the observation group were significantly shorter/lower than those in the control group(P<0.05).The observation group had significantly shorter time of first exhaust and defecation after surgery,as well as lower incidence of postoperative bloating,compared with the control group(P<0.05).Conclusion For overweight or obese patients undergoing laparoscopic hysterectomy in the Trendelenburg position,oral intake of 300 mL carbohydrate 2 hours before anesthesia does not increase the risk of regurgitation or aspiration,with safety and reliability.It not only can improve comfort of patients and promote post-anesthesia awakening,but also can reduce the incidences of intraoperative hypothermia and gastrointestinal adverse reactions,which is conducive to accelerating postoperative recovery.

Objective:To investigate the clinical efficacy of a self-designed assistant device for distal ulnar osteotomy and reduction in the surgical treatment of ulnar impaction syndrome.Methods:A retrospective analysis was performed to study the clinical data from the 27 patients with ulnar impaction syndrome who had been treated by distal ulnar shortening and fixation with 2 screws between January 2022 and August 2024 at Department of Hand and Foot Surgery,Affiliated Hospital of Jining Medical University. The cohort included 6 males and 21 females, with 13 left and 14 right sides affected and a mean age of (40.3±10.8) years (range: from 17 to 59 years). Based on their different assistant methods in osteotomy, the patients were divided into group A (15 cases) subjected to conventional freehand osteotomy and group B (12 cases) subjected to distal ulnar osteotomy and reduction assisted by our self-designed assistant device. Comparisons were made between the 2 groups regarding operative time, bone healing time, Mayo wrist function score at postoperative 16 weeks, number of the patients returning to their original occupations and complications.Results:There were no significant dif- ferences in the baseline characteristics between the 2 groups ( P>0.05). All patients were followed up postoperatively for (27.1±11.1) weeks (range: from 16 to 50 weeks). In group B, the operative time [50.0 (50.0, 62.5) min] and bone healing time [6.5 (6.0, 7.0) weeks] were significantly shorter than those in group A [80.0 (67.5, 92.5) min and 7.5 (6.8, 9.0) weeks] ( P<0.05). At postoperative 16 weeks, the Mayo wrist function score was 90.0 (85.0, 96.8) points for group A and 92.5 (85.0, 98.8) points for group B, showing no significant difference ( P>0.05). Five patients in group A and 4 ones in group B returned to their original work status, showing no significant difference either ( P>0.05). One case of non-union occurred in group A while no complication occurred in group B, demonstrating no significant difference either ( P>0.05). Conclusion:In the surgical treatment of ulnar impaction syndrome, compared with conventional freehand osteotomy, application of our self-designed assistant device for distal ulnar osteotomy and reduction is simple, less invasive, and comparable in functional recovery of the wrist, but superior in operative time and bone healing time.

Aim To investigate the anti-Zika virus(ZIKV)mechanism of diterpenoid compound 9 from Euphorbia helioscopia in vitro.Methods The cytotox-icity of compound 9 was evaluated using the CCK-8 as-say.A ZIKV-infected Vero cell model was established,and the antiviral activity was assessed through RT-qPCR,plaque assay,Western blot,and immunofluores-cence.Furthermore,the mechanism of action was elu-cidated using multi-cell line validation,nanoparticle tracking analysis,cellular thermal shift assay,and mo-lecular docking.Results In Vero cells,compound 9 exhibited an EC50 of(3.95±0.15)μmol·L-1 and a CC50 of(272.12±8.56)μmol·L-1,demonstrating significantly higher antiviral efficacy than the positive control drug ribavirin(RBV).Its virus inactivation effect was time-dependent and could significantly re-duce viral load and plaque formation.Studies revealed that compound 9 altered the physicochemical properties of ZIKV particles,including reducing surface charge and increasing particle size distribution.Additionally,it significantly enhanced the thermal stability of the prM protein.Molecular docking analysis indicated that compound 9 formed a high-affinity interaction with the prM protein(binding energy:-38.52 kJ·mol-1)and stabilized its structure through hydrophobic interac-tions.Conclusion Compound 9 exerts in vitro anti-ZIKV activity by directly inactivating the virus,disrup-ting viral particle integrity,and targeting the prM pro-tein.
