Objective:To explore the safety key points of total pancreaticoduodenectomy in the era of vascular resection technology and the important factors affecting rapid postoperative recovery.Methods:The clinical data of 52 patients with pancreatic cancer who underwent total pancreaticoduodenectomy in Beijing Chaoyang Hospital Affiliated to Capital Medical University from November 2014 to September 2022 were retrospectively analyzed, including 34 males and 18 females, aged (62±9). The intraoperative situation, incidence of postoperative complication, postoperative blood glucose control and postoperative survival rate were analyzed.Results:All operations of the 52 patients were successfully completed, including 48 patients underwent total pancreaticoduodenectomy combined with portal vein resection and allograft vascular grafts via artery approach. The portal vein occlusion time was (20±5) min. The incidence of postoperative complications was 28.8% (15/52), including 2 cases of abnormal gastric empty, 2 cases of diarrhea, 2 cases of chylous fistula, 4 cases of abdominal infection, 1 case of gastrointestinal fistula, 3 cases of gastrointestinal bleeding, and 1 case of pulmonary infection. Subcutaneous short-acting insulin injection was used to control blood glucose in the early stage after surgery, short-acting insulin combined with long-acting insulin was used for subcutaneous injection before sleep for diet recovery. All patients did not experience uncontrolled hyperglycemia. The median survival time of 52 patients was 13 months, and the longest follow-up time was 38 months. There were 37 patients died of tumor recurrence, 4 patients died of cardiovascular and cerebrovascular accidents, and 1 patient died of pulmonary infection in the 42 died patients.Conclusions:Total pancreaticoduodenectomy via artery approach can improve the R 0 resection rate in pancreatic cancer patients with vascular invasion, the rate of postoperative complication and mortality has no significant increase. The postoperative blood sugar control is satisfactory and the quality of life is guaranteed.

Objective:To explore the impacts of cyclic RNA asparagine hydroxylase(CircASPH)targeting the miR-28-5p/insulin-like growth factor 1 receptor(IGF-1R)axis on the proliferation,migration,and invasion of ovari-an granulosa cells in polycystic ovary syndrome(PCOS).Methods:Human ovarian granulosa cells KGN and COV434 were used as research subjects,the targeting relationship among CircASPH,miR-28-5p,and IGF-1R was confirmed through dual luciferase reporter gene experiments and pull down experiments.KGN and COV434 cells were grouped into si-NC group,si-ASPH group,si-ASPH+anti NC group,and si-ASPH+anti miR-28-5p group.The mRNA expression levels of CircASPH,miR-28-5p,and IGF-1R mRNA were detected by qRT-PCR,cell proliferation,migration,and invasion were detected by MTT assay,Edu staining,and transwell cell assay,respec-tively;and Western blot was applied to detect the expression of proliferating cell nuclear antigen(PCNA),matrix metalloproteinase-2(MMP-2),vimentin,N-cadherin,E-cadherin,and IGF-1R proteins.Results:Bioinformatics a-nalysis and dual luciferase reporter gene experiments showed that CircASPH,IGF-1R and miR-28-5p had targe-ted binding sites.Compared with si-NC group,the expression level of CircASPH,OD490 value,Edu positive cell rate,cell migration and invasion number,MMP-2,vimentin and N-cadherin in si-ASPH group were decreased,while the expression level of miR-28-5p and E-cadherin protein were increased,and the differences were statisti-cally significant(P<0.05).Compared with the si-ASPH+anti-NC group,the expression level of miR-28-5p and E-cadherin in the si-ASPH+anti-miR-28-5p group were decreased,and the OD490 value,Edu positive cell rate,cell migration and invasion number,MMP-2,vimentin and N-cadherin were increased,the differences were statisti-cally significant(P<0.05).Conclusions:In KGN and COV434 cells,inhibiting the expression of CircASPH can inhibit the proliferation,migration,invasion,and epithelial-mesenchymal transition of ovarian granulosa cells by reg-ulating the miR-28-5p/IGF-1R axis,which may become a new target for the treatment of PCOS.

Objective To observe the value of preoperative CT radiomics models for predicting composition of in vivo urinary calculi.Methods Totally 543 urolithiasis patients were retrospectively enrolled and divided into calcium oxalate monohydrate stone group(group A,n=373),anhydrous uric acid stone group(group B,n=86),carbonate apatite group(group C,n=30),ammonium urate stone group(group D,n=28)and ammonium magnesium phosphate hexahydrate stone group(group E,n=26)according to the composition of calculi,also divided into training set and test set at the ratio of 7:3.Radiomics features were extracted and screened based on plain CT images of urinary system.Five binary task models(model A-E corresponding to group A-E)and a quinary task model were constructed using least absolute shrinkage and selection operator algorithm for predicting the composition of calculi in vivo.Then receiver operating characteristic curves were drawn,and the area under the curves(AUC)were calculated to evaluate the predictive efficacy of binary task models,while the accuracy,precision,recall and F1 score were used to evaluate the predictive efficacy of the quinary task model.Results All binary task models had good efficacy for predicting the composition of urinary calculi in vivo,with AUC of 0.860-0.948 in training set and of 0.856-0.933 in test set.The accuracy,precision,recall and F1 score of the quinary task model for predicting the composition of in vivo urinary calculi was 82.25％,83.79％,46.23％and 0.596 in training set,respectively,while was 80.63％,75.26％,43.48％and 0.551 in test set,respectively.Conclusion Binary task radiomics models based on preoperative plain CT had good efficacy for predicting the composition of in vivo urinary calculi,while the quinary task radiomics model had high accuracy but relatively poor stability.
