Novel surgical procedure for preventing anastomotic leakage following colorectal cancer surgery: A propensity score matching study.

Hypoperfusion is the main cause of anastomotic leakage (AL) following colorectal surgery. The conventional method for evaluating anastomotic perfusion is to observe color change and active bleeding of the resection margin of the intestine and the pulsation of mesenteric vessels. However, the accuracy of this method is low, which may be due to insufficient observation time.

Targeted profiling of polar metabolites in cancer metabolic reprogramming by hydrophilic interaction liquid chromatography-tandem mass spectrometry.

Metabolic reprogramming of cancer cells is a hallmark of cancer, in which the polar metabolites involving aerobic glycolysis, pentose phosphate pathway (PPP), tricarboxylic acid (TCA) cycle, and glutaminolysis play a crucial role in the occurrence and development of cancer. Therefore, targeted analysis of the polar metabolites in these pathways is of great value for understanding cancers, finding diagnostic biomarkers, and identifying therapeutic targets. However, it is still challenging to directly determine polar metabolites in these pathways without derivatization due to their diverse chemical properties, isomers, and strong polarity.

Tubulocystic oncocytoma of the kidney: a case study and review of literature with focus on implications for differential diagnosis.

Renal oncocytoma (RO) can rarely present with a multilocular or tubulocystic growth pattern that may cause significant diagnostic difficulties with a variety of cystic renal cell carcinomas (RCC). Distinguishing these RO variants from their many RCC mimickers is critical because of its typical benign clinical course. Herein, we report a case of RO with extensive tubulocystic architectures on a 42-year-old female patient and discuss the clinicopathologic characterizations of this unusual RO variant with an emphasis on the wide spectrum of differential diagnoses of a variety of primary or secondary renal tumors that are featuring of both oncocytic cell changes and tubulocystic growth patterns.

ceRNA in cancer: possible functions and clinical implications.

Competing endogenous RNAs (ceRNAs) are transcripts that can regulate each other at post-transcription level by competing for shared miRNAs. CeRNA networks link the function of protein-coding mRNAs with that of non-coding RNAs such as microRNA, long non-coding RNA, pseudogenic RNA and circular RNA. Given that any transcripts harbouring miRNA response element can theoretically function as ceRNAs, they may represent a widespread form of post-transcriptional regulation of gene expression in both physiology and pathology.
