This review aims to analyze the current applications of open surgery, laparoscopic surgery, and robotic surgery in the treatment of colorectal cancer, particularly in elderly patients.It compares the differences among these three surgical methods in terms of surgical indicators, as well as short-term and long-term outcomes.Studies have shown that laparoscopic surgery has become the standard treatment for colorectal cancer, resulting in fewer postoperative complications and faster recovery times.While robotic surgery offers advantages in surgical precision and maneuverability, it is associated with longer surgical times and higher costs.For elderly patients, laparoscopic surgery has demonstrated fewer surgical complications and shorter hospital stays, with no significant difference in long-term survival rates compared to open surgery.However, there is limited research on the application of robotic surgery in elderly patients.Future studies should involve larger-scale, multi-centre randomized controlled trials to provide higher-level evidence and scientific guidance for the individualized treatment of elderly colorectal cancer patients.

Objective:This study aimed to clarify clinicopathologic characteristics, postoperative complications, and related risk factors of elderly patients with gastric cancer.Methods:A total of 395 patients(≥65 years old)who underwent radical gastrectomy for gastric cancer in Beijing Hospital from January 2014 to December 2021 were enrolled in this study.The patients were divided into the common elderly group(age<80 years, n=340)and the high-age group(age ≥ 80 years, n=55). Postoperative complications were classified into medical and surgical types.The clinicopathological characteristics and complications were compared between the two groups.Logistic regression models(univariate and multivariate)were used to identify the risk factors for postoperative complications.Results:The common elderly group was 65-79 years old(mean age: 71.5±4.3 years), with 263 male(77.4%); The high-age group was 80-89 years old(mean age: 82.6±2.6 years), with 42 male(76.4%). The comorbidity rate and the number of comorbidities in the high-age group were significantly higher than those in the common elderly group.The American Society of Anesthesiologists(ASA)scores and nutritional risk screening(NRS)2002 scores in the high-age group were significantly higher than those in the common elderly group(both P<0.05), and the activities of daily living(ADL)scores in the high-age group were significantly lower than that in the common elderly group( P<0.001). There were no statistically significant differences in tumor location, degree of differentiation, pathological type, T stage, and N stage between the two groups(all P>0.05). The overall postoperative complication rate in the high-age group was significantly higher than that in the common elderly group(38.2% vs.24.7%, P=0.036); the medical complications were significantly increased in the high-age group(21.8% vs.10.9%, P=0.022), whereas the surgical complications did not increase significantly(25.5% vs.17.1%, P=0.135). Multivariate analysis revealed that the number of comorbidities ≥2( HR=2.502, 95% CI: 1.275-4.911, P=0.008), preoperative NRS 2002 scores ≥5( HR=2.714, 95% CI1.294-5.693, P=0.008), and preoperative ADL scores<100( HR=2.012, 95% CI1.010-4.009, P=0.047)were independent risk factors for medical complications.Additionally, ASA grade ≥ 3( HR=2.586, 95% CI: 1.444-4.632, P=0.001)and proximal or distal gastrectomy( HR=2.397, 95% CI: 1.237-4.574, P=0.009)were independent risk factors for surgical complications. Conclusions:The occurrence of postoperative medical complications in very elderly patients with gastric cancer undergoing radical surgery has increased, while the rate of surgical complications has not increased.Moreover, advanced age itself is not an independent risk factor for postoperative complications.More attention should be paid to medical complications, and the management of commodities and nutritional support should be strengthened during the perioperative period.

Objective To analyze the modeling and evaluation method for vascular restenosis animal models in the last 10 years,to provide a reference for improving animal models of vascular restenosis.Methods Literature related to vascular restenosis was retrieved from mainstream Chinese and English databases from 2013 to 2023.Data on experimental animal strains,modeling method,modeling cycles,and detection method were extracted from the included literature,and a database was established using Excel for summary analysis.Results Among the 122 identified articles,the main experimental animals were rats,rabbits,and pigs,and most animals were male.The most common modeling method was balloon injury,and the modeling cycle was mainly within 4～8 weeks.The main detection indexes were histopathology,accounting for 37.18％,including routine hematoxylin-eosin,Masson,and Elastica van Gieson(EVG)staining.Conclusions The translatability of porcine vascular restenosis models is currently more in line with expectations,but their cost is high and they are unpopular,and rats and rabbits thus remain the main animal models.Balloon injury is the main mode of modeling.Different animal models and modeling method for vascular restenosis have advantages and disadvantages,and the model should be selected according to the experimental purpose.Animal models of vascular restenosis still have some limitations,however,and better animal models are required in the future.

Objective:To explore the active ingredients of shengxian and jinshuiliujun decoction with the method of network pharmacology, and to verify the experimental mechanism of its treatment of silicosis.Methods:In May 2023, the active ingredients and targets of drugs in shengxian and jinshuiliujun decoction were obtained through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database. The target of silicosis disease was screened by databases such as Genecards, Disease Gene Network (DisGeNET), Comparative Toxicogenomics Database (CTD), etc. The screened drug targets and disease targets were intersected to obtain the target set of shengxian and jinshuiliujun decoction for the treatment of silicosis. Protein-protein interaction (PPI) network analysis was performed on the target set through STRING database, and core target genes were screened. GO enrichment analysis and KEGG pathway analysis of intersection genes were performed based on Metascape database, and molecular docking verification of key components and targets of shengxian and jinshuiliujun decoction was carried out. Twenty-four adult male SD rats with SPF grade were randomly divided into control group, model group and TCM intervention group, with 8 rats in each group. The dust-stained rat model was prepared by non-tracheal exposure of 1 ml silica suspension (50 mg/ml) in one go, and TCM intervention group was given shengxian and jinshuiliujun decoction[6 g/ (kg·d) ] on the second day. The CT of the lungs of each group was observed 28 days after the dust-stained rat model. Paraffin sections of rat lung tissues were prepared and stained with Hematoxylin-Eosin (HE) and Masson. Western blot was used to verify the expression of core target-related proteins in rat lung tissues after the intervention of shengxian and jinshuiliujun decoction for 28 days, and the differences in protein expression between groups were compared by one-way analysis of variance.Results:A total of 205 active ingredients and 3345 active compounds were selected from shengxian and jinshuiliujun decoction, corresponding to 281 targets, among which 240 targets were related to silicosis. Serine/threonine kinase 1 (AKT1), tumor protein p53 (TP53), tumor necrosis factor (TNF) and interleukin (IL) 6 may be the key targets of shengxian and jinshuiliujun decoction in the treatment of silicosis. Through enrichment analysis, 30 GO entries and 20 potential signaling pathways were screened according to P-value, including nuclear factor κB (NF-κB), mitogen-activated protein kinase (MAPK) and cancer signaling pathways. Molecular docking showed that the active compounds of shengxian and jinshuiliujun decoction had good binding with the core target proteins, and the strongest binding properties were beta-sitosterol and TNF-α (-10.45 kcal/mol). In animal experiments, the inflammatory infiltration and fibrosis of lung tissue of rats in TCM intervention group were significantly improved. Compared with control group, the levels of TNF-α, IL-1β, IL-6 and NF-κB in lung tissue of model group were significantly increased ( P<0.05). Compared with model group, the lung injury of rats in TCM intervention group was significantly improved, and the expressions of TNF-α, IL-1β, IL-6 and NF-κB were significantly decreased ( P<0.05) . Conclusion:Shengxian and jinshuiliujun decoction in the treatment of silicosis may play an anti-fibrosis role by inhibiting the NF-κB signal transduction pathway mediated by inflammatory factors such as TNF-α and IL-1β, which provides a reference for further exploring the material basis and mechanism of its action.

Background It is a research hotspot to study the changes of metabolites and metabolic pathways in the process of coal worker's pneumoconiosis (CWP) by metabonomics and to explore its pathogenesis. Objective To study the change of metabolites in bronchoalveolar lavage fluid (BALF) of patients with CWP and explore the metabolic regulation mechanism of the disease. Methods Patients with CWP who met the national diagnostic criteria according to Diagnosis of occupational pneumoconiosis (GBZ 70-2015) and underwent massive whole lung lavage were selected as the case group, and patients with tracheostenosis who underwent bronchoscopy were selected as the control group. BALF samples were collected from the cases and the controls. After filtering out large particles and mucus, the supernatant was stored in a −80 ℃ refrigerator. The samples were detected and analyzed by liquid chromatography-mass spectrometry after adding extraction solution, cold bath ultrasonication, and high-speed centrifugation, and the metabolic profiles and related data of CWP patients were obtained. The differential metabolites related to the occurrence and development of CWP were screened by multiple statistical analysis; furthermore, we searched the Kyoto Encyclopedia of Genes and Genomes (KEGG) database for potential metabolic pathways involved in the progression. Results There was no significant difference in the general conditions of the subjects, such as weight, height, age, and length of service among the stage I group, the stage II group, the stage III group, and the control group (P˃0.05). When comparing the CWP stage I group with the control group, 48 differential metabolites were screened out, among which 14 were up-regulated and 34 were down-regulated. A total of 66 differential metabolites were screened out between the patients with CWP stage II and the controls, 14 up-regulated and 52 down-regulated differential metabolites. Compared with the control group, 63 differential metabolites were screened out in the patients with CWP stage III, including 11 up-regulated and 52 down-regulated differential metabolites. There were 36 differential metabolites that may be related to the occurrence of CWP, among which 11 differential metabolites were up-regulated, and 25 were down-regulated. Four significant differential metabolic pathways were identified through KEGG database query: linoleic acid metabolic pathway, alanine metabolic pathway, sphingolipid metabolic pathway, and glycerophospholipid metabolic pathway. Conclusion The metabolomic study of BALF show that there are 36 different metabolites in the occurrence and development of CWP, mainly associating with linoleic acid metabolism, alanine metabolism, sphingolipid metabolism, and glycerophospholipid metabolism pathways.
