Circular RNA hsa_circ_0001322 (circ1322) was demonstrated to be significantly reduced in expression in gastric cancer patients in our previous study, and changes in its expression were significantly correlated with lymph node metastasis. However, the underlying workings of circ1322 in gastric cancer are still not fully understood. Therefore, to confirm the effect of circ1322 on gastric cancer, we examined the expression of circ1322 in gastric cancer cells and tissues.

Background/aims: There are many studies on immune cell infiltration in colorectal cancer, including FoxP3+-regulatory T cells, CD66b+ tumorassociated neutrophils, and CD163+ tumor-associated macrophages. These studies mainly focus on the relationship between cell infiltration and tumor progression, prognosis, and so on, while the relationship between tumor cell differentiation and cell infiltration is poorly understood. We aimed to explore the relationship between cell infiltration and tumor cell differentiation.

Introduction: The infiltration of immune cells in tumor tissue is affected by the tumor microenvironment. However, the relationship between the infiltration of regulatory T cells (Tregs), tumor-associated neutrophils (TANs) and tumor-associated macrophages (TAMs) in colorectal cancer (CRC) remains unclear.

Material And Methods: Tissue microarray and immunohistochemistry were used to detect the infiltration of FoxP3 Tregs, CD66b TANs and CD163 TAMs in 249 CRC samples (training cohort) and 243 CRC samples (validation cohort).

Background: Sarcopenia is a nutrition-related disease and has a profound effect on the long-term overall survival (OS) of patients with gastric cancer. Its diagnostic criterion is critical to clinical diagnosis and treatment. However, previous research reported widely differing sarcopenia prevalence due to different criteria.

Background: This study aimed to explore the prognostic significance of tumor-associated macrophage (TAM) infiltration in colorectal cancer (CRC) patients.

Methods: Tissue microarray and immunohistochemistry were used to detect the infiltration of CD163+ TAMs in 209 CRC samples, and the Kaplan-Meier method was used for survival analysis. Cox proportional hazards analysis was used for univariate analysis and multivariate analysis of clinically relevant confounders.

Article Synopsis
  • The study aimed to identify and evaluate the expression of 60 microRNAs (miRNAs) in gastric cancer tissues to find potential biomarkers for metastasis.
  • The methods involved analyzing 30 gastric cancer tissues and paired normal tissues using a specific technique called stem-loop real-time reverse transcription-polymerase chain reaction, followed by a secondary assessment on 22 more samples.
  • Results showed that 38 miRNAs had significantly different expressions in cancer tissues, with miR-212 and miR-195 identified as potential independent biomarkers for predicting lymph node metastasis in gastric cancer due to their high sensitivity and specificity.

Liver malignancy is known to be associated with hepatolithiasis. The present report summarises the results and our experience for management of 23 patients with intrahepatic hepatolithiasis associated cholangiocarcinoma (IHHCC). The correct diagnosis rates of US (ultrasonography), CT (computed tomography), and MRCP (magnetic resonance cholangiopancreatography) were 82.

Objective: To evaluate the enhancing effects of ginsenoside Rg3 combined with mitomycin C and tegafur (MF) on postoperative chemotherapy in advanced gastric cancer.

Methods: Seventy-one postoperative patients with advanced gastric cancer were randomly divided into two groups, the control group (n=33), which received treatment with only MF (Mitomycin C+Tegafur), and the trial group (n=38), which were treated with ginsenoside Rg3+MF. The serum VEGF levels in the control group and trial group were detected preoperatively and postoperatively, meanwhile, the serum VEGF levels in 30 healthy persons were detected as comparison.

Aim: To explore the clinicopathological and molecular genetic features of hereditary nonpolyposis colorectal cancer (HNPCC) in Chinese population.

Methods: We collected 16 Chinese HNPCC families from Wenzhou, Zhejiang Province, China. Tumor tissues and peripheral white blood cells were studied using microdissection, microsatellite analysis, immunostaining of hMSH2 and hMLH1 proteins and direct DNA sequencing of hMSH2 and hMLH1 genes.

Objective: To study the clinicopathological and molecular genetic characteristics of hereditary nonpolyposis colorectal cancer (HNPCC), to enable the early diagnosis and to evaluate the treatment.

Methods: We analyzed 12 families of HNPCC from Wenzhou, Zhejiang province, China. Mismatch repair genes hMSH2 and hMLH1 expression and microsatellite instability of tumor tissue were studied using microdissection, microsatellite analysis, immunohistochemical staining and Gene Scan analysis.

Objective: To explore etiologic fraction (EF) and interaction of serum hepatitis B surface antigen (HBsAg) carriage and other risk factors for primary hepatocellular carcinoma (PHC) in Wenzhou, Zhejiang, China.

Methods: 1:1 matched case-control study was carried out in Wenzhou, with 180 cases of PHC and 180 controls. EF and interactions of serum positive HBsAg [HBsAg(+)] and other risk factors for PHC were analyzed by Mantel-Haenszel stratified method and conditional multiple logistic regression.
