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.

AIM To evaluate the quality of Changmaile Capsules(Ⅰ).METHODS The analysis was performed on a 35℃ thermostatic Thermo Scientific AccucoreTM XL C18 column(4.6 mm×250 mm,4 μm),with the mobile phase comprising of methanol-acetonitrile-0.5% phosphoric acid flowing at 1 mL/min in a gradient elution manner,and the detection wavelengths were set at 230,280 nm.The contents of gastrodin,danshensu,quercetin-3-O-β-D-glucose-7-O-β-D-gentiobioside,3′-hydroxypuerarin,puerarin,3′-methoxypuerarin,puerarin apioside,daidzin,rosmarinic acid,lithospermic acid,ononin,daidzein,salvianolic acid B,calycosin,paeoniflorin and isoquercitrin were determined,after which HPLC fingerprints were established,along with the calculation of similarities.RESULTS Sixteen constituents showed good linear relationships within their own ranges(r≥0.999 0),whose average recoveries were 87.4%-103.9% with the RSDs of 0.54%-3.10% .At 230 nm,the fingerprints of ten batches of samples demonstrated similarities of 0.954-0.999,which displayed obvious differences at 280 nm.3′-Hydroxypuerarin,puerarin,3′-methoxypuerarin,puerarin apioside,daidzin and daidzein were main differential constituents,paeoniflorin and isoquercitrin exhibited stable contents in various batches of samples.CONCLUSION This simple,accurate and reliable method can be used for the quality control of Changmaile Capsules(Ⅰ).

OBJECTIVETo investigate the effect and influence factors on knee joint peripheral fractures and/or dislocations with an associated vascular injury through retrospectively study.

METHODSFrom March 2002 to November 2007 31 patients with knee joint peripheral fractures and/or dislocations with an associated vascular injury were treated, including 24 males and 7 females with a mean age of 41 years (range from 21 to 62 years). Definite diagnosis of vascular injury by combining colored ultrasonic, CTA, operative exploration with clinical signs, fixing fractures and/or dislocations with fixators, plates and screws, reconstructing blood circulation based on the condition of the vascular injury by vascular repair, homograft vein or artificial vascular grafting separately and analysing the effects of PSI, diagnosis and treatment methods on salvage lower extremities.

RESULTSSuccessful reconstruction was carried out in 31 cases, however there were 1 death because of mult-fractures and brain injury and 6 amputation, 24 cases successful salvage followed up mean 24.2 months, 6 cases bone nonunion and infected bone defect were cured by delayed bone planting or bone transportation. Ligaments repair reconstruction of 7 cases knee joint dislocation were done in delayed 3 or 4 weeks after first operation, the good functional rate was 71.4%.

CONCLUSIONSThe patients of PSI under 10 grades in knee joint peripheral fractures and/or dislocations with an associated vascular injury should been carried out treatment, early definite diagnosis and blood circulation reconstruction are the key factors of successful salvage treatment.

OBJECTIVETo construct the recombinant adenovirus encoding antisense c-myc fragment and to investigate its effect on the chemotherapy sensitivity of osteosarcoma MG-63 cells to cisplatin.

METHODSThe recombinant adenovirus (Ad-Asc-myc) encoding antisense c-myc fragment was constructed by cloning c-myc cDNA of about 720 base pairs in a reverse direction into adenovirus vector, then undergoing recombination, amplifying and being complemented in vivo. The osteosarcoma MG-63 cells were transfected by the Ad-Asc-myc in vitro, and Wright staining, Acridine Orange staining, Western Blot, MTT, Flow Cytometry (FCM) were used to study cell morphology, expression of c-myc protein, tumor cell proliferation in vitro, apoptosis and cell cycle change.

RESULTSAd-Asc-myc encoding antisense c-myc fragment was obtained with the titer of 2 x 10(9) pfu/ml. Ad-Asc-myc down-regulated the expression of c-myc protein after transfected MG-63 cells for 48 h, combined with the treatment of 2.0, 5.0 microg/ml cisplatin for 2 h could inhibit tumor cells proliferation in vitro by 33.4% and 54.2% respectively, which were significantly difference compared with control recombinant adenovirus (Ad-LacZ) groups (P < 0.05). Acridine Orange staining and FCM analysis showed that Ad-Asc-myc could induce apoptosis of transfected cells, which was enhanced by the treatment of cisplatin cell. Cycle analysis showed that obvious G2/M phase arrested in transfected cells.

CONCLUSIONAd-Asc-myc increases the chemotherapy sensitivity of osteosarcoma MG-63 cells to cisplatin as well as induced apoptosis.
