Objective:To investigate the influencing factors for textbook outcome (TO) after hepatectomy for hepatolithiasis.Methods:The retrospective case-control study was conducted. The clinicopathological data of 216 patients with hepatolithiasis who were admitted to The First Affi-liated Hospital of Anhui Medical University from January 2015 to March 2023 were collected. There were 69 males and 147 females, aged 61(range, 22-85)years. Observation indicators: (1) treatment situations; (2) TO after hepatectomy; (3) Influencing factors for TO after hepatectomy. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers. Logistic regression models were used for univariate and multifactorial analyses. Results:(1) Treatment situations. All the 216 patients underwent hepatectomy, including 45 cases of laparoscopic hepatectomies and 171 cases of open hepatectomies, 161 cases of anatomical hepatectomies and 55 cases of non-anatomical hepatectomies. All the 216 patients underwent intraoperative choledochoscopy exploration and lithotripsy. There were 170 patients with normal Oddi sphincter function and 46 patients with Oddi sphincter dysfunction. All the 216 patients underwent biliary drainage, including 198 cases of external T-tube drainage and 18 cases of internal bile-intestinal drainage. The operation time was (226±75)minutes and volume of intraoperative blood loss was (106±82)mL. There were 29 patients with perioperative blood transfusion and 14 patients with intraoperative severe adverse events. There were 189 patients achieved immediate stone clearance. Of 183 patients with intraoperative bile cultures, 76 cases were positive for bacteria culture. (2) TO after hepatectomy. Of 216 patients, 93 cases had postoperative complications, all of which were successfully discharged after active treatment. One patient had surgery-related death within 90 days after surgery, and the cause of death was liver failure. Five patients were readmitted within 90 days after surgery, and 18 patients had postoperative stone residual. Of 216 patients, 164 cases achieved TO postoperatively and 52 cases did not achieve TO postoperatively. (3) Influencing factors for TO after hepatectomy. Results of multivariate analysis showed that cholangitis, stone distribution, surgical approaches, anatomical hepatectomy, immediate stone removal and postoperative review of choledochoscopy were independent influencing factors for TO after hepatectomy in patients with hepatolithiasis ( P<0.05). Conclusion:Cholangitis, stone distribution, surgical approaches, anatomical hepatectomy, imme-diate stone removal and postoperative review of choledochoscopy are independent influencing factors for TO after hepatectomy in patients with hepatolithiasis.

Objective:To analyze the occurrence of and risk factors for skin and mucosal infections after primary tumor resection in patients with paraneoplastic pemphigus, and to summarize relevant nursing experience.Methods:Clinical characteristics and postoperative skin and mucosal infections were retrospectively analyzed in patients with confirmed paraneoplastic pemphigus, who underwent primary tumor resection in Department of Dermatology, Peking University First Hospital between January 1999 and January 2021. Common infectious agents were analyzed, and infection-related risk factors were identified by logistic regression analysis.Results:A total of 44 patients with paraneoplastic pemphigus were included in this study, including 25 (56.8%) males and 19 (43.2%) females, and their age were 33.8 ± 15.4 years. Postoperatively, 21 (47.73%) patients developed skin and mucosal infections, and their postoperative hospital stay (median [ Q1, Q3]) was 38 (25, 60) days, which was significantly longer than that in patients without skin and mucosal infections (21 [12, 23] days, Z = -4.08, P < 0.001) . The most common pathogen was methicillin-resistant Staphylococcus aureus (15 cases, 34.09%) . High glucocorticoid dosage per kilogram of body weight ( OR = 1.21, 95% CI: 1.00 - 1.46, P = 0.047) and receiving assisted ventilation therapy ( OR = 9.20, 95% CI: 2.01 - 42.13, P = 0.004) were independent risk factors for postoperative skin and mucosal infections. After active treatment and care, 37 (84.1%) patients recovered well at discharge. Conclusion:Skin and mucosal infections are a common postoperative complication in patients with paraneoplastic pemphigus, and the pathogens are mostly drug-resistant bacteria, which can lead to prolonged hospital stay, so attention should be paid to postoperative skin care; high postoperative glucocorticoid dosage per body weight and respiratory support may be associated with postoperative skin and mucosal infections.
RÉSUMÉ
Background and Objectives@#This study was to investigate the role of microRNA-29a-3p (miR-29a-3p) in human bone marrow mesenchymal stem cells (hBMSCs), and its relationship with steroid-associated osteonecrosis. @*Methods@#and Results: The online tool GEO2R was used to screen out the differentially expressed genes (DEGs) in GSE123568 dataset. Quantitative real time-polymerase chain reaction (qRT-PCR) was performed to detect the expression of miR-29a-3p, forkhead box O3 (FOXO3), alkaline phosphatase (ALP), bone gamma-carboxyglutamate protein (OCN) and RUNX family transcription factor 2 (Runx2) in the hBMSCs isolated from the patients with steroid-associated osteonecrosis. CCK-8 assay was executed to measure cell viability; western blot assay was utilized to detect FOXO3, ALP, Runx2, OCN and β-catenin expression. Cell apoptosis and cell cycle were detected by flow cytometry. Immunofluorescence assay was used to detect the sub-cellular localization of β-catenin. Bioinformatics analysis and luciferase reporter gene assay were performed to confirm whether miR-29a-3p can combine with FOXO3 3’UTR. MiR-29a-3p was markedly up-regulated in the hBMSCs of patients with steroid-associated osteonecrosis, while FOXO3 mRNA was significantly down-regulated. Transfection of miR-29a-3p mimics significantly inhibited the hBMSCs’ proliferation, osteogenic differentiation markers’ expressions, including ALP, Runx2, OCN, and repressed the ALP activity, as well as promoted cell apoptosis and cell-cycle arrest. FOXO3 was identified as a target gene of miR-29a-3p, and miR-29a-3p can inhibit the expression of FOXO3 and β-catenin, and inhibition of miR-29a-3p promoted translocation of β-catenin to the nucleus. @*Conclusions@#MiR-29a-3p can modulate FOXO3 expression and Wnt/β-catenin signaling to inhibit viability and osteogenic differentiation of hBMSCs, thereby promoting the development of steroid-associated osteonecrosis.

Objective: To study the effect of the stress distribution with three dimensional(3-D) finite element analysis technique between zirconia all-ceramic crown of maxillary central incisors and agglomerant with different thickness. Methods: A 3-D finite element model of all-ceramic crown (core layer and the veneer layer), agglomerant, tooth, tooth root and alveolar bone was established from CBCT data. The agglomerant thickness was designe as 50, 100 and 150 μm respectively. After a load simulating occlusion was imposed on to the model the stress distribution of agglomerant layer, the equivalent of veneer layer and the maximum principal stress were analysed. Results: With the increase of agglomerant thickness and the change of occlusion, the maximum principal stress of all ceramic crowns gradually increased, the equivalent stress increased first and then decreased, the equivalent stress and the maximum principal stress of agglomerant layer showed a downward trend. Conclusion: The use of agglomerant layer with the thickness of 50 μm is feasible for the bond of all ceramic crowns and may reduce the risk of veneer chipping.
