Background: Ubiquitination, a major post-translational modification, significantly impacts tumorigenesis, progression, and prognosis. This study aims to classify colon cancer at the molecular level and create a reliable signature using ubiquitination-related genes (URGs) to assess the immune microenvironment and prognosis.
Methods: We employed non-negative matrix factorization to subtype colon cancer based on ubiquitination-related gene (URG) expression patterns.

We aimed to investigate the branching pattern and trajectory of LCA and measure the distances from the root of the IMA to the origin of the LCA (D mm) and from the origin of LCA to intersection of LCA and IMV (d mm) during laparoscopic left-sided colorectal operations.
Methods: We analyzed 106 patients who underwent laparoscope-assisted left-side colorectal surgery during laparoscopic surgery.
In recent years, natural orifice specimen extraction surgery (NOSES) in the treatment of colorectal cancer has attracted widespread attention. The potential benefits of NOSES including reduction in postoperative pain and wound complications, less use of postoperative analgesic, faster recovery of bowel function, shorter length of hospital stay, better cosmetic and psychological effect have been described in colorectal surgery. Despite significant decrease in surgical trauma of NOSES have been observed, the potential pitfalls of this technique have been demonstrated.

Methods: Three hundred patients with colorectal cancer who underwent curative resection in the First Affiliated Hospital of Zhengzhou University between February 2014 and May 2016 were included. Patients were classified into open surgery group, laparoscopic surgery group, and robot-assisted group.
Aripiprazole (ARP) is an atypical anti-psychotic drug widely used to treat schizophrenia and bipolar disorder. The pharmacological effects of ARP on cancer cells are still poorly understood. In this study, anti-cancer effects of ARP on various malignant tumor cells and its molecular mechanism were further carefully examined by using cell proliferation assay, xenograft mouse model, immunoblotting analysis, migration assay, luciferase reporter gene assay, kinase assay, and overexpression strategy.

Methods: In all, 321 cases of T1-stage CRC were selected from 10132 patients with CRC who received surgical therapy in six large-scale hospitals in China and were retrospectively analyzed. Univariate and multivariate analyses were performed to analyze the risk factors for lymphatic metastasis.
Long non-coding RNAs (lncRNAs) are increasingly implicated in tumorigenesis and cancer progression. This study focused on the relationship between the lncRNA LINC00959 and colorectal cancer (CRC). We found that LINC00959 expression was lower in CRC tissues than normal colorectal mucosae.

This study was aimed to investigate the effect of miR-590-3p on the cell proliferation and metastasis via Hippo pathway in colorectal cancer (CRC).

Methods: A total of 258 PLWH were recruited from two provinces of China.
Cytokine-induced killer (CIK) cells have achieved therapeutic benefit in treatment of solid tumors in clinic. However, some patients show no response after CIK treatment. Animal assays have shown that successful infiltration of CIK cells to the tumor sites could affect the outcome.

Background: Amplified in breast cancer 1 (AIB1) has been shown to promote growth and invasion in several types of human cancers and to have a prognostic role in some of cancers. However, its prognostic significance in hepatocellular carcinoma (HCC) remains unknown. This study aimed to address the issue.

Objective: To explore the relationship between the expression of aquaporin 4 (AQP4) and slow transit constipation(STC).
Methods: The expression of AQP4 in the ascending colon mucosa of 45 patients with STC was detected by immunohistochemistry. The transit time of stool was measured with barium sulfate suspensions.
Background: In patients suffering from acute pancreatitis, the pathogenesis is not completely understood, and several recent studies in vitro suggested that heat shock proteins might play an important role in cell signaling. To investigate the possible role of extracellular heat shock protein 70 (Hsp70) in pancreatitis, toll-like receptor-4 (TLR4)-deficient and wild-type mice were administered with exogenous Hsp70 during the course of cerulein-induced pancreatitis (CIP).
Methods: Acute pancreatitis was induced by 5 intraperitoneal injections of cerulein at hourly intervals, and then treated with recombinant Hsp70 through the caudal vein 4 hours after the start of cerulein injections.
Objectives: To investigate the expression of caspase-8 and -10 in rectal adenoma, adenocarcinoma and the corresponding normal mucosa tissue, and to clarify the relationship between their expression and clinicopathological parameters of rectal cancer.
Methods: The expression of caspase-8 and -10 was determined by real-time RT-PCR and immunohistochemistry in 36 rectal adenomas, 93 rectal cancers and 93 corresponding normal rectal mucosa samples.
Results: Compared with normal mucosa, the mRNA expression of caspase-8 was higher in adenomas (p = 0.
Objective: To examine E1AF mRNA expression and to determine whether it is correlated with tumor progression and matrilysin in human rectal cancer.
Methods: Real-time RT-PCR was used to determine E1AF and matrilysin expression in 100 matched rectal cancers and normal tissues.
Results: Among the 100 rectal cancers, 69 cases of E1AF mRNA overexpression were observed.
Objective: To investigate the relationship between cyclin D2 and P210(BCR/ABL) tyrosine kinase in chronic myelogenous leukemia (CML).
Methods: RT-PCR, Western blot and flow cytometry were performed to detect the expression of cyclin D2 in K562 cells and in K562-ib-eGFP cells which express intracellular single-chain antibody (sFv, intrabody) against ABL tyrosine kinase domain.
Results: Cyclin D2 expression in K562-ib-eGFP cells was 18.

Objective: To study the effects of anti-ABL tyrosine kinase intrabody on the growth of human chronic myelogenous leukemia (CML) cells in nude mice.
Methods: A recombinant retroviral vector MSCV-ibE-IRES-eGFP was constructed to express intracellular single-chain antibody (intrabody) against ABL tyrosine kinase domain in CML cells. K562 cells were transduced with the retrovirus, eGFP+ cells were then selected by fluorescence-activated cell sorting (FACS).
