738; 95% CI 1.359-2.223; P<0.001). A nomogram was drawn by risk score and clinical features.

The prognostic signature could predict the survival of CC by survival-receiver operating characteristic (ROC) curve [area under the curve (AUC) =0.810]. A nomogram was drawn by risk score and clinical features, and its c-index and calibration curve demonstrated that the prognostic signature could independently predict the prognosis of CC (P<0.001). Gene set enrichment analysis (GSEA) confirmed that the genes were significantly enriched in cancer- and autophagy-related pathways (P<0.05).

This 10 autophagy-related lncRNA signature has prognostic potential for CC. More important roles in the CC biology of these lncRNAs may be identified with further study.

The growth hormone inhibitor somatostatin and its analogs are promising therapeutic agents for acute pancreatitis. However, the therapeutic effects remain controversial. Somatostatin analogs preferentially bind to somatostatin receptor 2 (SSTR2), and this study aimed to investigate whether N-glycosylation affects SSTR2 stability, membrane trafficking, and signal transduction.

Western blot analysis following PNGase F digestion was performed to confirm N-glycosylation of SSTR2 in rat pancreatic acinar AR42J cells. Rats were subjected to 4 hourly intraperitoneal injections of cerulein (50 µg/kg) plus LPS (5 µg/mL) to induce acute pancreatitis. Fluspirilene manufacturer Mass spectrometry was conducted to identify the glycosylation sites of SSTR2, and immunofluorescent staining was carried out to examine the localization of wild-type and asparagine 9 (N9)Q-mutant SSTR2. Proteasome inhibitor MG132 was employed to assess the stability of SSTR2, and overexpression of wild-type or N9Q-mutant SSTR2 was used to examine the role of N-glycosyl stability, and signal transduction of SSTR2 in pancreatic cells, playing a protective role in experimental acute pancreatitis.

Postoperative delirium (POD) is a common complication of major surgery and is associated with fortified morbidity, mortality, and long-term cognitive dysfunction. This study sought to evaluate the incidence and risk factors of delirium in elderly (aged ≥65 years) patients who underwent coronary artery bypass grafting (CABG).

We performed a retrospective cohort analysis. The clinical data of 1,426 elderly patients who underwent CABG at our hospital from October 2018 to October 2020 were collected and analyzed. Delirium was defined as any positive Confusion Assessment Method for Intensive Care Unit examination following surgery during the intensive care unit (ICU) stay. Risk factors for POD were authenticated via univariate and multivariate logistic regression analyses. The intraoperative and postoperative factors were evaluated using a propensity score-matched regression analysis based on preoperative factors.

A total of 39.3% (560 of 1,426) of elderly patients who underwent CABG were diagnosed with delietes, stroke, and extracardiac arteriopathy were independent risk factors for POD in these patients. In relation to the intraoperative and postoperative factors, after adjusting for preoperative confounding factors, only a prolonged ICU stay was identified as a risk factor for POD. Additionally, high levels of HDL-C may be beneficial in reducing the incidence of delirium.

The incidence of POD in elderly patients undergoing CABG was high. Factors such as older age, long-term alcohol consumption, diabetes, stroke, and extracardiac arteriopathy were independent risk factors for POD in these patients. In relation to the intraoperative and postoperative factors, after adjusting for preoperative confounding factors, only a prolonged ICU stay was identified as a risk factor for POD. Additionally, high levels of HDL-C may be beneficial in reducing the incidence of delirium.

Medulloblastoma (MB) is a common central nervous system tumor in children with extensive heterogeneity and different prognoses. This study aimed to classify the Ki-67 index in MB with radiomic characteristics based on multi-parametric magnetic resonance imaging to guide treatment and assess the prognosis of patients.

Three sequences of T1W, CE-T1W, and T2W were used as test data. Two experienced radiologists manually segmented the tumors according to T2W images from 90 patients. The patients were divided into training and test sets at a ratio of 73, and 833 dimensional image features were extracted for each patient. Five models were trained using the feature set selected in three ways. Finally, the area under the curve (AUC) and accuracy (ACC) were used on the test set to evaluate the performance of the different models.

A random forest (RF) model combining three sequence features achieved the best performance (ACC 0.771, 95% CI 0.727 to 0.816; AUC 0.697, 95% CI 0.614 to 0.78). The voting model that combined a RF and a support vector machine (SVM) had higher performance than the other models (ACC 0.796, 95% CI 0.76 to 0.833; AUC 0.689, 95% CI 0.615 to 0.763). The best prediction model that used only one sequence feature was voting in the T2W sequence (ACC 0.736, 95% CI 0.705 to 0.766; AUC 0.636, 95% CI 0.585 to 0.688). The ensemble model was better than the single training model, and a multi-sequence combination was better than a single sequence prediction. The multiple feature selection methods were better than a combination of the two methods.

A model obtained by machine learning could help doctors predict the Ki-67 values of patients more efficiently to make targeted judgments for subsequent treatments.

Previous studies have shown that platelet is involved in the occurrence and progression of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH), but the relationship between platelet and DCI is not completely clear. Here, we aimed to screen the early platelet parameters associated with DCI after aSAH and develop an early predictive nomogram for DCI after aSAH.

The study was carried out in the neurosurgery department of Affiliated Hospital of North Sichuan Medical College. A total of 285 consecutive aSAH patients admitted within 24 hours after onset were analyzed retrospectively. Univariate and multivariate analyses were used to identify risk factors for DCI. A predictive nomogram was developed and validated with R software.

Sixty-six (23.16%) of the 285 patients with aSAH exhibited DCI during hospitalization. The DCI group and the non-DCI group showed statistically significant differences in red blood cell count (RBC), platelet count (PLT), mean platelet volume (MPV), modifieder aSAH. The nomogram incorporating early MPV had greater value in predicting DCI after aSAH.

Effective traction and dissection of the esophagus are key steps during thoracoscopic esophagectomy. In traditional methods, a separate trocar for the traction instruments or thoracic punctures are adopted to externally retract the esophageal loop. However, both methods bring about chest wall damage that is associated with increased morbidity and mortality. The magnetic anchoring and traction system can not only achieve exposure and pulling multi-directional flexible but also reduce the number of transthoracic ports and trocars used, and then avoid the chopstick effect in surgery. We aimed to verify the feasibility and safety of a self-designed magnetic anchoring and traction system in assisted thoracoscopic esophagectomy.

Ten healthy pigs were used as the experimental objects. A magnetic anchoring and traction system composed of an external unit and internal unit was designed, then the requirements and stress characteristics of esophageal pulling and exposure during thoracoscopic esophagectomy were analyzed. The internal unit was introduced through the 5th intercostal space port and was secured to the right wall of the esophagus, the external unit was placed on the surface of the chest wall to allow pairing with the internal unit. The external unit was moved on the chest wall to help exposing operative field.

Ten pigs underwent a 3-port thoracoscopic esophagectomy using a magnetic anchoring and traction technique, and all operations were successful. The system provided adequate traction force to pull the esophagus. The external unit could move freely outside the chest wall, enabling suitable positioning of the esophagus for dissection.

The novel magnetic anchoring and traction system in thoracoscopic esophagectomy is safe and feasible, and has the potential for clinical application.

Artificial intelligence (AI) is used to solve the problem of missed diagnosis of polyps in colonoscopy, which has been proved to improve the detection rate of adenomas. The aim of this review was to evaluate the diagnostic performance of AI-assisted detection and classification of polyps in colonoscopy.

The literature search was undertaken on 4 electronic databases (PubMed, Web of Science, Embase, and Cochrane Library). The inclusion criteria were as follows studies reporting AI-assisted detection and classification of polyps; studies containing patients, images, or videos receiving AI-assisted diagnosis; studies which included AI-assisted diagnosis and reported classification based on histopathology; and studies providing accurate diagnostic data. Non-English language studies, case-reports, reviews, meeting abstracts and so on were excluded. The Quality Assessment of Diagnostic Accuracy Studies-2 scale was used to evaluate the quality of literature and the Stata 13.0 software was used to perform meta-anapected to be a novel auxiliary diagnosis method. Our study has inevitable limitations including heterogeneity due to different AI systems and the inability to further analyze the specificity and sensitivity of AI for different types of endoscopes.

Disruption of the DNA damage repair (DDR) gene is related to cancer progression, treatment selection, and is subjected to radiation and targeted therapies with limited success. This paper conducted a comprehensive analysis to explore the distribution of DDR mutations in Chinese pan-cancer patients.

A total of 10,284 consecutive cases were analyzed in 24 cancer types [non-small cell lung cancer (NSCLC) 29.0%, liver 12.0%, colorectum 10.7%, etc.]. Tumor tissue samples were subjected to next generation sequencing (NGS) using a 381 gene panel incorporating 100 microsatellite loci. The association of deleterious somatic DDR mutation (del-sDDR

) with tumor mutational burden (TMB), microsatellite instability (MSI), programmed cell death-ligand 1 (PD-L1) expression of pan-cancers was evaluated. Genomic and clinical data from public cohorts of immunotherapy were analyzed to demonstrate the association between del-sDDR

and clinical survival.

Del-sDDR

were found in 802 (7.6%) of all cases, and were most common in cancers of the endometrium, prostate, bladder, etc.
