The concept of precision surgery is closely linked to advancements in modern medical technology and the interdisciplinary integration, profoundly influencing the direction of sur-gical decision-making and treatment paradigms. At its core, precision surgery aims to strike a balance among lesion removal, organ preservation, and damage control by leveraging key surgical technolo-gies that emphasize visualization, quantification, and controllability, ultimately maximizing patient benefits. In the field of liver cancer diagnosis and treatment, the concept of precision surgery should be integrated throughout the entire course of disease management, including preoperative precision evaluation, intraoperative meticulous procedures, and postoperative careful management. The reali-zation of these advanced concepts depends on continuous technological advancements and process optimization. However, the current diagnosis and treatment of liver cancer still face numerous challenges, such as accurate preoperative assessment of tumor biological behavior, optimization of intraoperative precision resection techniques, and improvement of postoperative recurrence moni-toring and intervention strategies. By employing technologies such as molecular imaging, circulating biomarkers, and artificial intelligence, the concept and practice of precision surgery can be further refined and seamlessly integrated into every stage of liver cancer management. This approach pro-mises to enhance surgical safety and efficacy, offering patients more scientific and efficient treatment options. The authors systematically explain the application of precision surgery concept in the diag-nosis and treatment of liver cancer and the thinking of the future development direction.

BACKGROUND:Total flavonoids from Sophora flavescens have a variety of pharmacological effects,including anti-inflammatory,immunomodulatory,antioxidant,and anti-hepatic injury,but the therapeutic effects and mechanisms in non-alcoholic fatty liver disease are not clear.OBJECTIVE:To reveal the mechanism of total flavonoids from Sophora flavescens in the treatment of non-alcoholic fatty liver disease using bioinformatics,network pharmacology and zebrafish experimental validation.METHODS:A zebrafish model of non-alcoholic fatty liver disease was constructed to observe lipid accumulation,pathomorphologic changes,and expression of inflammatory genes in the liver of zebrafish after treatment with total flavonoids from Sophora flavescens.The active ingredients of total flavonoids from Sophora flavescens and non-alcoholic fatty liver disease-related targets were obtained from TCMSP,Swiss Target Prediction,and Bat-man databases.STRING was used to perform protein-protein interaction network analysis,GO functional enrichment and KEGG pathway enrichment analysis.Based on the GSE33814 dataset,the differentially expressed genes of total flavonoids from Sophora flavescens and non-alcoholic fatty liver disease intersection targets were screened out.Correlation analysis and receiver operating characteristic curve were performed using R4.3.2 software.Core genes were verified by the validation set GSE89632.RT-qPCR and western blot assays were performed to verify the expression of core pathway-related genes and proteins.RESULTS AND CONCLUSION:(1)Total flavonoids from Sophora flavescens could improve lipid accumulation in the liver of zebrafish with non-alcoholic fatty liver disease,significantly inhibited the elevation of lipid and aminotransferase levels in zebrafish(P<0.05),and regulated the expression of genes related to inflammation and lipid metabolism.(2)A total of 168 common targets were obtained using the network pharmacology,and top 10 core genes,identified by Cytoscape topology analysis,were HSP90AA1,STAT3,PIK3R1,MAPK1,AKT1,RXRA,PIK3CA,EGFR,JAK2,and ESR1.GO and KEGG analysis pathways mainly included insulin resistance,lipids,and atherosclerosis.There were a total of 59 differentially expressed genes after intersection of total flavonoids from Sophora flavescens and non-alcoholic fatty liver disease targets.The receiver operating characteristic curve and validation set analyses yielded six core targets that were significantly different between healthy individuals and patients with non-alcoholic fatty liver disease(P<0.01).(3)RT-PCR and western blot results verified that total flavonoids from Sophora flavescens inhibited the activation of the JAK2/STAT3 signaling pathway in zebrafish.To conclude,total flavonoids from Sophora flavescens may alleviate the inflammatory response through the JAK2/STAT3 signaling pathway,thus inhibiting lipid accumulation and improving non-alcoholic fatty liver disease.

Objective:To evaluate the clinical outcomes of mandibular angle osteotomy combined with wing-shaped genioplasty for the correction of low-angle mandibular prominence with microgenia.Methods:A retrospective analysis was conducted on patients who underwent mandibular angle osteotomy and wing-shaped genioplasty at the Second Hospital of Nanjing between January 2020 and December 2022. Preoperative three-dimensional computed tomography and lateral cephalograms were obtained, and relevant parameters were measured, including the Frankfort horizontal plane to mandibular plane angle (∠FH-MP), the lower lip to soft tissue pogonion angle (∠LiaV-Pog) and the facial height index (FHI). Based on the measurements, surgical experience, and patient preference, the osteotomy lines for the mandibular angle and the wing-shaped genioplasty were designed. During the procedure, mandibular angle osteotomy and wing-shaped genioplasty were performed in accordance with the preoperative surgical plan. The distal genial segment was advanced and inferiorly repositioned according to the predetermined measurements and rigidly fixed to the bilateral mental tubercles using titanium plates and screws. The bone segments resected from the mandibular angle were then longitudinally split into either single- or double-layer bone grafts. These grafts were meticulously implanted into the interpositional gap at the genial region to optimize chin projection and refine the lower facial contour. Postoperative monitoring included assessments of wound healing, complications and lower facial contour. At the final follow-up, lateral cephalograms were taken for remeasurement, and patient satisfaction was surveyed. Statistical analysis was performed using SPSS 22.0 software. Pre- and postoperative data for ∠FH-MP, ∠LiaV-Pog, and FHI were presented as Mean ± SD and compared using paired t-tests, with a P-value < 0.05 considered statistically significant. Results:Twelve female patients, aged 22-35 years (mean 28.3), were included. The follow-up period ranged from 6 to 24 months. All surgical sites achieved primary healing without early complications such as hemorrhage, hematoma, or wound infection. However, all patients experienced transient mental numbness, which resolved within 3 to 6 months. All patients achieved a smooth and natural mandibular contour. CT scans confirmed satisfactory survival of the grafted bone. All patients expressed satisfaction with the aesthetic outcomes. Postoperative measurements of ∠FH-MP, ∠LiaV-Pog, and FHI were (25.2±4.6)°, (24.0±1.2)°, and (52.0±1.3)%, respectively, which were significantly improved compared to the preoperative values of (16.8±5.9)°, (36.5±4.8)°, and (66.0±4.3)% (all P < 0.01). Conclusion:The combination of mandibular angle osteotomy and wing-shaped genioplasty is an effective and safe procedure for correcting low-angle mandibular prominence with microgenia. This technique significantly increases the mandibular plane angle, creates a natural and smooth mandibular contour, and yields stable result with high patient satisfaction.

BACKGROUND:Copper is an essential trace element and plays a key role in series of physiological activities in the body.Metabolic disturbance of copper is closely associated with multiple diseases.Copper metabolism is mainly involved in the absorption,transport,storage and excretion of copper ions,and all the above processes regulate copper homeostasis in the body.In recent years,many studies have confirmed that copper homeostasis disorder severely affects the metabolic activities of the body and cause diseases in various systems.Besides,the role of copper in oral diseases has been of great interest.OBJECTIVE:To explore the role of copper in occurrence,development,and treatment of oral diseases,and provide a comprehensive overview of research advances in this field.METHODS:The first author searched relevant studies on copper in oral diseases using a computer in PubMed,Web of Science,and CNKI.The key words were"Cu,copper,copper metabolism,oral diseases,oral squamous cell carcinoma,periodontitis,oral submucous fibrosis,oral lichen planus,recurrent oral ulceration,pultitis"in English and Chinese.After screening,78 articles were included for further review and analysis.RESULTS AND CONCLUSION:(1)Patients with oral squamous cell carcinoma have elevated concentrations of copper in serum and saliva,and elevated copper promotes cancer progression through oxidative stress and promoting angiogenesis.Excessive elevation or reduction of copper concentration in tumor cells can inhibit the growth of tumor cells.The combination of copper and anticancer drugs can significantly improve the efficacy of drugs.(2)The concentration of copper in the serum of patients with periodontitis is increased,and excessive copper can aggravate periodontitis through promoting oxidative stress.Combination of copper and drugs can promote periodontal bone regeneration and periodontal tissue healing.(3)The level of copper is positively correlated with degree of oral mucosa fibrosis.Copper that enters the oral mucosa promotes fibrosis of oral mucosa by enhancing activity of lysyloxidase to increase production of collagen.(4)Copper levels are elevated in patients with oral lichen planus,and elevated copper may promote the progression of oral lichen planus by modulating immune cell function.(5)In patients with recurrent oral ulcers,serum copper level is significantly increased,and utilization of copper becomes disordered,which could decrease copper-containing enzyme activity,thus affecting the healing of ulcers.Copper is closely associated with multiple oral diseases and therapies targeting at copper could obviously enhance the therapeutic effect of drugs.But further studies are still needed to uncover its mechanisms to lay foundation for the better treatment of oral diseases.

Objective:To analyze interobserver variability in endoscopic diagnostic accuracy of chronic atrophic gastritis (CAG) among endoscopists with varying levels of experience.Methods:Endoscopic examination data from 247 patients who underwent endoscopy from January 2021 to June 2024 at Department of Gastroenterology, the First Affiliated Hospital of Army Medical University ( n=154), Renmin Hospital of Wuhan University ( n=35) and Shanxi Provincial Coal Central Hospital ( n=58) were retrospectively collected. The collected images were reviewed by an expert panel of three individuals with the title of deputy chief physician or above. The final endoscopic Kimura-Takemoto classification diagnosis of the expert panel was regarded as the golden standard. Fourteen endoscopists from the above three centers provided their Kimura-Takemoto classification diagnosis. These endoscopists were divided into the junior group ( n=7, with experience of <2 000 procedures) and the senior group ( n=7, with experience of >10 000 procedures). The difference in the accuracy of endoscopic Kimura-Takemoto classification diagnosis between the groups were analyzed. Results:Diagnostic accuracy for Kimura-Takemoto classification ranged from 65.99% (163/247) to 86.64% (214/247) in the senior group with the overall accuracy of 77.27% (1 336/1 729). The junior group exhibited diagnostic accuracy ranging from 36.44% (90/247) to 72.47% (179/247) with the overall accuracy of 62.12% (1 074/1 729). The senior group demonstrated higher overall diagnostic accuracy than that of the junior group ( χ 2=93.27, P<0.001). The diagnostic accuracy of non-CAG in the senior group was higher than that in the junior group [83.73% (463/553) VS 72.33% (400/553), χ 2=20.27, P<0.001]. The diagnostic accuracy of C-type atrophy in the senior group was higher than that in the junior group [90.10% (801/889) VS 82.79% (736/889), χ 2=19.66, P<0.001] .The diagnostic accuracy of O-type atrophy in the senior group was higher than that in the junior group [83.97% (241/287) VS 68.29% (196/287), χ 2=18.56, P<0.001]. Conclusion:Interobserver variability is observed in the diagnostic accuracy of endoscopic Kimura-Takemoto classification for CAG among endoscopists with different experience levels. Experienced endoscopists exhibit higher diagnostic accuracy for CAG compared with their less experienced counterparts.

Objective To investigate the status of feeding intolerance in patients with enteral nutrition after lung transplantation and analyze its influencing factors,to provide a reference for formulating a reasonable enteral nutrition plan and improving patients'nutritional status.Methods Convenient sampling method was used to retrospectively collect the clinical data of 115 patients who received enteral nutrition support after lung transplantation and were hospitalized in the ICU of a tertiary hospital in Guangdong Province from August 2022 to November 2023.According to the occurrence of feeding intolerance during ICU hospitalization,the patients were divided into a feeding tolerance group and a feeding intolerance group.Univariate and logistic regression analysis were used to analyze the influencing factors of feeding intolerance patients with enteral nutrition after lung transplantation.Results Within 7 days of initiating enteral nutrition,a total of 63 patients developed feeding intolerance,with an incidence of 54.78％.Among them,the incidence of feeding intolerance was relatively high within 1 to 3 days after initiating enteral feeding.The clinical manifestations of feeding intolerance were diarrhea,bloating,gastric retention,vomiting/regurgitation,among which the diarrhea was the highest incidence(87.30％).Logi-stic regression analysis showed that intraoperative net balance volume(OR=0.999),intraoperative blood transfusion(OR=1.001)volume and diabetes history(OR=0.170)were independent influencing factors for feeding intolerance in patients with enteral nutrition after lung transplantation(P＜0.05).Conclusion There was a high incidence of feed-ing intolerance in patients with enteral nutrition after lung transplantation.Patients undergoing lung transplantation who have a high net intraoperative fluid balance,receive a low volume of intraoperative blood transfusions,and have a history of diabetes are at a lower risk of developing feeding intolerance when receiving postoperative enteral nutrition.When starting enteral nutrition,medical staff should dynamically evaluate the risk factors of feeding intolerance,screen high-risk patients as early as possible,and formulate reasonable enteral nutrition programs to improve the nutritional status of patients and promote their rehabilitation.
