ObjectiveTo compare the hepatic bile acid profile between a mouse model of metabolic-associated steatohepatitis （MASH） induced by a high-fat， high-sugar， and high-cholesterol diet combined with intraperitoneal injection of 10% carbon tetrachloride （CCl₄） and MASH cases in clinical practice， and to investigate the feasibility of this model in studying drug interventions on bile acid profile in MASH. MethodsA total of 30 male C57BL/6J mice were randomly divided into control group and model group， with 15 mice in each group. The mice in the control group were given normal diet and drinking water and weekly injections of olive oil， and those in the model group were given a high-fat， high-sugar， and high-cholesterol diet， high-sugar drinking water， and weekly injections of CCl₄+olive oil. At the end of weeks 8， 12， and 16， 5 mice were selected from each group to collect samples. Behavioral assessments were performed， and body weight and liver wet weight were measured； liver pathology and lipid deposition were evaluated by HE staining， SAF scoring， oil Red O staining， the semi-quantitative analysis of stained area， the serum levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST）， and liver triglyceride （TG） content； Sirius Red staining was performed for liver tissue to assess liver fibrosis； ultra-performance liquid chromatography-tandem mass spectrometry and targeted metabolomics were used to measure the hepatic bile acid profile， including cholic acid （CA）， glycocholic acid （GCA）， chenodeoxycholic acid （CDCA）， glycochenodeoxycholic acid （GCDCA）， ursodeoxycholic acid （UDCA）， tauroursodeoxycholic acid （TUDCA）， hyodeoxycholic acid （HDCA）， and glycodeoxycholic acid （GDCA）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. ResultsCompared with the control group at the same time point， the model group had disheveled and dull fur， reduced activity， and relatively slow reactions at weeks 8， 12， and 16， as well as significant increases in liver wet weight （P<0.05）， the serum level of ALT （P<0.05）， the content of TG in the liver （P<0.05）， and SAF score （P<0.05）. As for the differentially expressed bile acids in liver tissue， compared with the control group at week 8， the model group had significantly higher levels of CA and CDCA and significantly lower levels of UDCA， TUDCA， HDCA， and GDCA （all P<0.05）； compared with the control group at week 12， the model group had significantly higher levels of CA， GCA， CDCA， and GCDCA and significantly lower levels of UDCA and HDCA （all P<0.05）； compared with the control group at week 16， the model group had significantly higher levels of CA， GCA， CDCA， GCDCA， and TUDCA and significantly lower levels of UDCA， HDCA， and GDCA （all P<0.05）. As for the differentially expressed bile acids in the bile acid pool of liver tissue， compared with the control group at week 8， the model group had significantly higher levels of CA and CDCA and significantly lower levels of UDCA， TUDCA， GDCA， and HDCA （all P<0.05）； compared with the control group at weeks 12 and 16， the model group had significantly higher levels of GCA and GCDCA and significantly lower levels of UDCA， GDCA， and HDCA （all P<0.05）. ConclusionThere are significant changes in the hepatic bile acid profile in a mouse model of MASH induced by a high-fat， high-sugar， and high-cholesterol diet combined with CCl₄， which are similar to the changes in bile acids in MASH cases in clinical practice， suggesting that this model can be used to explore the interventional effect of drugs on the bile acid profile in MASH.

Objective:To explore the potential of integrating virtual surgery with three-dimensional (3D) printed guides in the surgical management of mandibular benign tumors and subsequent reconstruction of bone defects.Methods:A retrospective analysis was conducted on the clinical data of patients who underwent computer-assisted resection and vascularized fibular flap reconstruction for benign mandibular tumors at the Department of Oral and Maxillofacial Surgery, First Affiliated Hospital of Zhengzhou University, from June 2013 to December 2020. According to the utilization of guide plates for mandibular and fibular osteotomy during surgical procedures or not, the patients were categorized into two cohorts: a guide plate cohort and a non-guide plate cohort. In the guide plate group, custom-designed gudie plates based on virtual surgical plans were fabricated using 3D printing technology and employed intraoperatively; In the non-guide plate group, surgery was exclusively performed based on virtual surgical plan and prebent titanium plate without any supplementary plating. The measured outcomes included fibular flap osteotomy, operation duration, and clinical flap survival. Computed tomography images obtained one week post-surgery were utilized to assess the intersegmental commissure degree between fibular segments as well as between fibular segments and mandible, commissure degree between fibular segments and prebent titanium plate, and condyle position. The satisfaction of patients with their facial appearance was evaluated 6 months after the surgery using a visual analogue scale. Statistical analysis was conducted using SPSS 21.0 software. Independent sample t-tests was utilized to compare the duration of operation and and postoperative evaluation of facial appearance, the Chi-square tests was utilized for condyle position, commissure degrees among interactions involving fibular segments, prebent titanium plates, bone segments( P<0.05 denoted statistical significance). Results:A total of 30 patients were enrolled, comprising 17 males and 13 females, with a median age of 24 years (16-64 years). The preparation process of fibular flaps proceeded smoothly. The required length of fibula was measured as (14.1 ± 1.9) cm (5.7-18.1 cm), while the number of fibular segments ranged from 2 to 4, averaging at approximately 2.9 ± 0.6. The mandibular defects were repaired using a single-layer fibula in 12 cases, a vascularized folded fibula in 7 cases and a combination of vascularized and non-vascularized fibula in 11 cases. The operation time for the guide plate group was recorded as ( 335.9 ± 64.0) min (240-433 min), while it was observed to be (470.7 ± 140.5 ) min (280-680 min) for the non-guide plate group.The postoperative follow-up duration ranged from 9 to 23 months, with an average period of 11 months. All fibular flaps demonstrated clinical survival. The number of patients with good commissure degree between fibular and mandibular segments, between prebent titanium plate and fibular and mandibular segments and the position of condyle were 15, 15 and 13 cases in guide plate group, 10, 13 and 11 cases in non-guide plate group respectively. The statistical analysis revealed a significant difference ( P<0.05) in the degree of commissure between the fibular and the mandibular segments (15/15 vs. 10/15) in the two groups. Both groups exhibited high levels of satisfaction regarding their postoperative facial appearance at the 6 months follow-up, observed to be 9.6±0.5 and 9.3±0.5 respectively, and the statisticla analysis revealed non-significant difference ( P>0.05). Conclusion:The integration of virtual surgery with 3D printed guide plates can effectively reduce operative time and improve precision in the repair and reconstruction of free-fibular flaps following resection of benign tumors of the mandible.

Objective:To investigate the therapeutic effect of digital technology assisted design of fibula flap for the repair of maxillary tumor defect and implant denture.Methods:A retrospective analysis was performed in patients with benign maxillary tumors who were admitted to Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Zhengzhou Universityfrom March 2018 to October 2020. Before the surgery, the virtual tumor resection, fibula reconstruction and stereomodels were printed for the fabrication of fibular osteotomy guide plates.And titanium plates were prefabricated with the stereomodels. Personalized titanium meshes were prebent manually. During the operation, the tumor was removed according to the osteotomy guide plate.The fibula was reshaped according to the surgical plan and the guide plate.And maxillary defects were reconstructed using the fibular flap combined with a prebent personalized titanium mesh.Straumann implants were implanted 6-9 months after bone grafting.The upper porcelain crown was repaired 3-4 months after implantation to restore the occlusal relationship and masticatory function. The facial appearance, masticatory function and peri-implant inflammation were followed up.Results:A total of 12 cases were included in this study, 7 males and 5 females, aged 20-55 years, with a median age 36 years old. Among them, there were 3 cases of ossifying fibroma, 7 cases of ameloblastoma, and 2 cases of odontogenic myxoma.According to the James Brown classification, there were 4 cases of Type Ⅱb, 3 cases of Type Ⅱc, 3 cases of Type Ⅱd, and 2 cases of Type Ⅲb. Tumor resection and fibula reconstruction went smoothly in 12 patients and all the free fibular flaps survived 14 days after surgery. The patients had maxillofacial symmetry, good occlusal relationship after the implant repair, and normal chewing and masticatory functions, after 12-48 months of follow-up, with an average of 26 months. The mouth opening reached 2.8-3.3 cm, without obvious peri-implantitis.Conclusion:The use of digital technology to design fibula flap to repair the defect after maxillary tumor resection and implant denture can not only restore the patients’ facial contour, but also restore their occlusal relationship and masticatory function.

Objective:To explore the effects of mindfulness-based decompression therapy on fear of disease progression, quality of life and sleep quality in patients with acute ischemic stroke, in order to provide intervention measures to alleviate fear of the disease progression degree and improve sleep and quality of life in patients with acute ischemic stroke.Methods:This study was a randomized controlled study. Using the convenience sampling method, 98 patients with acute ischemic stroke who attended the Department of Neurology at the Third Hospital of Hebei Medical University from November 2021 to September 2022 were selected for the study, and the study population was divided into experimental group ( n=49) and control group ( n=49) using the random number table method. The control group received conventional care, and the experimental group received mindfulness-based stress reduction therapy for 8 weeks in addition to conventional care. Compared the scores of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), Stroke-Specific Quality of Life Scale (SS-QOL), and Pittsburgh Sleep Quality Index (PSQI) between the two groups of patients before and after intervention using two independent sample t-tests, and further compared the score spread of each scale before and after intervention between the two groups of patients using Mann-Whitney U test. Results:In the experimental group, 4 cases fell off and 3 cases had imperfect questionnaire information, while in the control group, 2 cases fell off and 5 cases had imperfect questionnaire information. Finally, 42 cases were included in each group. The 23 males and 19 females in the control group aged (48.31 ± 7.61) years old, while 25 males and 17 females in the experimental group aged (50.19 ± 8.64) years old. There was no significant difference in FoP-Q-SF, SS-QOL and PSQI scores between the two groups before intervention (all P>0.05). After intervention, the scores of FoP-Q-SF and PSQI in the experimental group (35.79 ± 7.04, 7.19 ± 2.58) were lower than those in the control group (38.52 ± 4.02, 9.45 ± 2.28), while the SS-QOL score (200.36 ± 21.75) was higher than that in the control group (185.41 ± 15.90), the differences were statistically significant ( t=2.19, -4.26, 3.60, all P<0.05). After intervention, the scores of FoP-Q-SF and PSQI in the experimental group were lower than those before intervention (39.69 ± 4.15, 10.00 ± 2.85), while the SS-QOL score was higher than that before intervention (176.93 ± 23.54), the differences were statistically significant ( t=4.80, 10.45, -11.43, all P<0.05). The score spreads of FoP-Q-SF, SS-QOL, and PSQI in the experimental group before and after intervention were 1.00 (0.00, 9.25), 20.00 (12.75, 32.75), 3 (1, 4), which were higher than 1.00 (-1.25, 2.00), 5.50 (1.00, 10.25), 0 (-1, 2) in the control group, the differences were statistically significant ( Z=-2.30, -5.74, -5.53, all P<0.05). Conclusions:Mindfulness-based decompression therapy can effectively relieve the fear of disease progression and improve the quality of sleep and life in patients with acute ischemic stroke.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer (LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha (FAPα) expression in LNM-CRC cells. Gain- or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis (CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.

Adreno-cortical carcinoma(ACC)is an uncommon tumor,some of them may produce excessive steroid hormone.The prognosis of ACC is quite poor and current treatment options are relatively limited,especially for pa-tients whose tumor is metastatic and difficult to remove by surgical operation.This makes the management of ACC challenging.Existing studies have shown that the mechanisms of ACC are complex.The molecular changes happen in adrenocortical development and homeostasis may explain the occurrence of ACC.This review focuses on recent studies and summarizes the genetic and molecular mechanism changes that potentially associated with ACC in the development process of the adrenal cortex and multi-omics studies,including genomic changes,epigenetic changes,differences in non-coding RNA,immune microenvironment and features found through multi-omics analy-sis.This information may support screening of therapeutic targets of ACC in future.
