Objective To investigate the relationships between expressions of HPV and EBV in larynge-al carcinoma. Methods DNA flow-through hybridization and gene chip genotyping technology(HybriMax)and real-time quantitative PCR were used for 37 subtypes of HPV detection and quantitative detection of EBV in 101 cases of laryngeal cancer paraffin embedded tissue specimens. 43 cases of vocal cord polyp of paraffin embedded tissue specimens were used as the controls. Results The positive rate of laryngeal carcinoma was 13.86% in group HPV and 9.3% in the control group ,with no statistically significant difference between the positive expres-sions of HPV in the laryngeal carcinoma group and control group(P>0.05). The positive rate of laryngeal carci-noma was 63.37% and 13.95%,respectively ,in group EBV ,and the control group ,with significant difference between them(P < 0.05). In respect of the positive rate by comparing differently differentiated EBV in laryngeal carcinoma ,there was no significant difference in the positive expression of EBV in well differentiated and differen-tiated laryngeal carcinoma(P>0.05),but the difference was statistically significant in highly differentiated EBV as compared with those with low differentiation type,medium differentiation and poor differentiation(P < 0.05). There was no significant difference between the groups in view of sex ,age and course of disease in the patients (P > 0.05). Conclusions The incidence of laryngeal carcinoma is closely related with EBV infection ,possibly relationed with HPV and high-risk subtypes of HPV have a certain role in the process of induced laryngeal carcino-ma. The gender ,age and duration of disease have no significant correlation with EBV infection. This study will provide a basis for further invesgitation of pathogenesis of laryngeal cancer and prevention and treatment of larynge-al cancer.

Objective To construct the recombinant expression vector encoding antisense Tcf fragment for the blockage of abnormal Wnt pathway, and to investigate its effect on the biological behaviors of human hepatocarcinoma cells. Methods Antisense expression vector was transfected into hepatocarcinoma cells SMMC-7721 with GeneJammer. RT-PCR and Western blot were used to detect Tcf expression. Cell proliferation and motility were compared by growth curves and Transwell plate assay. Cell apoptosis was determined by Annexin V and cell cycle was examined by fluorescent staining. Results The stable transfection of antisense Tcf in SMMC-7721 cells significantly reduced Tcf expression at both mRNA and protein levels. Compared with parental and mock-transfected 7721 (7721-vector) cells, antisense Tcf RNA transfected cells 7721-pTas showed much decreased activities of proliferation, migration and invasion in vitro. Furthermore, the apoptosis rate of 7721-pTas cells [(26.34±2.07)%] was significantly higher than that of 7721-vector cells [(6.53±1.02)%] and parental SMMC-7721 cells [(4.33±0.68)%] (P<0.001). The percentages of G0-G1 phase antisense transfected cells were 20.24% and 20.95%, higher than parental SMMC-7721 and 7721-vector cells, and percentages of S phase antisense transfected cells were 11.8% and 11.38%, lower than parental SMMC-7721 and 7721-vector cells, respectively. Conclusions Antisense RNA suppress the growth ability of liver cancer cells by inducing cell apoptosis and impeding the progress of cell cycle, which suggests that selective blockage of abnormal Wnt signal pathway by antisense Tcf RNA may be a potential new gene therapy for liver cancer.

In previous study, the 150-ku oxygen-regulated protein(ORP150) was identified as a candidate glycoprotein related to hepatocellular carcinoma.In order to further validate the expression level of ORP150 in hepatocellular carcinoma, protein expression was determined by Western blot and cell immunochemistry, and messenger RNA(mRNA) expression was detected by quantitative real-time polymerase chain reaction.The effect of ORP150 on apoptosis and invasive potential of hepatocellular carcinoma cells was evaluated using the small interference RNA(siRNA) technique.Both the protein and mRNA expression levels of ORP150 were significantly upregulated in hepatocellular carcinoma cell lines compared with a non-tumor human liver cell line.After transfection with the specific siRNA of ORP150, significantly greater apoptosis of hepatocellular carcinoma cells was induced compared with untransfected cells.However, no significant effect on invasive potential was found.Overexpression of ORP150 was associated with hepatocellular carcinoma, and ORP150 might promote the proliferation of hepatocellular carcinoma cells by inhibiting apoptosis.ORP150 could be a potential therapeutic target for hepatocellular carcinoma.

Objective:To investigate the expression levels of peripheral blood lymphocytes in patients with high-grade squamous intraepithelial lesions (HSIL) of the cervix and early cervical cancer, and to analyze their correlation with the clinicopathological characteristics of cervical cancer.Methods:The clinical data of 65 patients with HSIL and 78 patients with early cervical cancer (2018 International Federation of Gynecology and Obstetrics stage ≤ stage Ⅱ A) treated in Shanxi Province Cancer Hospital from October 2020 to November 2021 were retrospectively analyzed, and 31 healthy people undergoing physical examination during the same period were treated as the healthy control group. The expressions of CD3 + T cells, CD4 + T cells, CD8 + T cells, NK cells, NK/T cells and other immune cells in fasting peripheral blood of the patients were detected by using flow cytometry. Results:The expression levels of CD3 + T cells, CD4 + T cells, CD4 +/CD8 + and NK cells were 71±8, 39±7, 1.5±0.5, 16±7, respectively in HSIL group, and 73±9, 41±9, 1.5±0.6, 16±9, respectively in early cervical cancer group, which were lower than those in the healthy control group (76±9, 45±10, 2.0±1.3, 20±7) (all P < 0.05). The expression levels of CD8 + T cells was 28±7, 29±8, respectively in HSIL group and early cervical cancer group, which were higher than those in the healthy control group (24±7) (all P < 0.05). The expression level of total B cells in early cervical cancer group was lower than that in healthy control group (10±4 vs.12±3, P < 0.05). The expression level of CD3 + T cells in peripheral blood of early cervical cancer patients with tumor diameter >4 cm and nerve/vascular invasion was 71±10 and 72±8, which was lower than that of patients with tumor diameter 2-4 cm, ≤2 cm and without nerve/vascular invasion (72±8, 75±8, 78±7); the expression level of CD8 + T cell was 32±8 and 35±4, which was higher than that of patients with tumor diameter 2-4 cm, ≤2 cm, and without nerve/vascular invasion (28±8, 28±7, 29±8) (all P < 0.05). The levels of CD3 + T cells and total B cells were negatively correlated with the tumor diameter (all P < 0.05), while the level of CD8 + T cells was positively correlated with tumor diameter ( P < 0.05); the levels of CD3 + T cells and NK cells were negatively correlated with nerve/vascular invasion (all P < 0.05). Conclusions:The immune function of the body starts to change in the early progression of cervical cancer, and is related to the tumor diameter and nerve/vascular invasion of cervical cancer.
