Hepatocellular carcinoma (HCC) is the most common subtype of liver cancer, and assessing its histopathological grade requires visual inspection by an experienced pathologist. In this study, the histopathological H&E images from the Genomic Data Commons Databases were used to train a neural network (inception V3) for automatic classification. According to the evaluation of our model by the Matthews correlation coefficient, the performance level was close to the ability of a 5-year experience pathologist, with 96.0% accuracy for benign and malignant classification, and 89.6% accuracy for well, moderate, and poor tumor differentiation. Furthermore, the model was trained to predict the ten most common and prognostic mutated genes in HCC. We found that four of them, including , , , and , could be predicted from histopathology images, with external AUCs from 0.71 to 0.89. The findings demonstrated that convolutional neural networks could be used to assist pathologists in the classification and detection of gene mutation in liver cancer.

Accumulating evidence suggests that the primary and acquired resistance of hepatocellular carcinoma (HCC) to sorafenib is mediated by multiple molecular, cellular, and microenvironmental mechanisms. Understanding these mechanisms will enhance the likelihood of effective sorafenib therapy.

N-methyladenosine-modified CircRNA-SORE sustains sorafenib resistance in hepatocellular carcinoma by regulating β-catenin signaling.

More than 30 cases of synovial sarcoma are sequenced on all organs of cBioPortal database, but it has not yet been reported before. Here, we reported a case of a 66-year-old male patient with an upper abdominal pain for half a month and a previous history of oral cancer. During this hospitalization, the patient underwent laparoscopic exploration followed by open pancreaticoduodenectomy. The histopathological diagnosis was pancreatic synovial sarcoma (PSS), and we further performed whole exome sequencing for this patient. We found that there are many copy number variations (CNV) of exon gene in all the 24 chromosomes, of which chr1, chr2, chr4 have the most exon gene amplification and chr21, chr22, chrY have the most exon gene deletion. Besides, GO (Gene Ontology) analysis showed that many driver-genes are related to chromosome or chromatin organization while KEGG (Kyoto Encyclopedia of Genes and Genomes) analysis demonstrated that many driver-genes are enriched in the cancer-related pathways. Furthermore, we found mutations or CNV of the five vital driver-genes in the results of sequencing, including  Of them,  and  in exon 1 are both in-frame mutations. By exploring the pathogenic genes of PSS, we have found some vital gene mutations and better understood the pathogenesis to promote the targeted treatment of primary PSS.

Enhanced recovery after surgery (ERAS) has shown sufficient superiority in terms of cutting down hospital stay and costs, and reducing complications in patients undergoing laparoscopic hepatectomy (LH). However, the benefit of ERAS in elderly patients undergoing LH remains unclear, and clinical studies on this topic are still limited.

Inflammatory bowel disease (IBD) is a chronic, immune-mediated inflammatory disease characterized by the destruction of the structure and function of the intestinal epithelial barrier. Due to the poor remission effect and severe adverse events associated with current clinical medications, IBD remains an incurable disease. Here, we demonstrated a novel treatment strategy with high safety and effective inflammation remission via tissue-adhesive molecular coating. The molecular coating is composed of o-nitrobenzaldehyde (NB)-modified Gelatin (GelNB), which can strongly bond with -NH on the intestinal surface of tissue to form a thin biophysical barrier. We found that this molecular coating was able to stay on the surface of the intestine for long periods of time, effectively protecting the damaged intestinal epithelium from irritations of external intestinal metabolites and harmful flora. In addition, our results showed that this coating not only provided a beneficial environment for cell migration and proliferation to promote intestinal repair and regeneration, but also achieved a better outcome of IBD by reducing intestinal inflammation. Moreover, the  experiments showed that the GelNB was better than the classic clinical medication-mesalazine. Therefore, our molecular coating showed potential as a promising strategy for the prevention and treatment of IBD.
