The clinicopatho-logical data of 119 patients with right hemicolon cancer who were admitted to Daping Hospital, Army Medical University from July 2016 to July 2019 were collected. There were 63 males and 56 females, aged (61±11)years. All the 119 patients underwent CME of right hemicolon. Of 119 patients, 37 cases undergoing Da Vinci robotic assisted CME of right hemicolon were divided into robotic group and 82 cases undergoing laparoscopic assisted CME of right hemicolon were divided into laparoscopic group. Observation indicators: (1) the propensity score matching conditions and comparison of general data between the two groups after propensity score matching; (2)intraoperative and postoperative situations; (3) postoperative pathological examination; (4)follow-up. Follow-up was conducted by outpatient examination or telephone interview to detect tumor metastasis and survival of patients after surgery up to August 2019. The propensity score matching was conducted by 1∶1 matching using the nearest neighbor method. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Count data were represented as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Kaplan-Meier method was used to calculate survival rate and the GraphPad Prism 5 software was used to draw survival curve. The Log-rank test was used for survival analysis. Results:(1) The propensity score matching conditions and comparison of general data between the two groups after propensity score matching: 68 of 119 patients had successful matching, including 34 cases in each group. Before propensity score matching, cases undergoing surgery by surgeon A or surgeon B were 32, 5 of the robotic group, versus 49, 33 of the laparoscopic group, showing a significant difference between the two groups ( χ2=8.381, P<0.05). After propensity score matching, the gender (males or females), age, body mass index (BMI), cases with tumor classified as stageⅠ, stage Ⅱ or stage Ⅲ of TNM staging, cases with tumor located at ileocecal region, ascending colon, hepatic flexor of colon or transverse colon, cases undergoing surgery by surgeon A or surgeon B were 17, 17, (62±10)years, (22.4±2.7)kg/m 2, 4, 14, 16, 3, 15, 10, 6, 29, 5 of the robotic group, versus 15, 19, (62±11)years, (22.4±2.8)kg/m 2, 4, 18, 12, 2, 19, 7, 6, 30, 4 of the laparoscopic group, showing no significant difference between the two groups ( χ2=0.236, t=0.127, 0.044, χ2=1.071, 1.200, 0.000, P>0.05).

Objective To predict the secondary structure and the B cell epitopes of human heparanase protein, and to identify its immunogenicity. Methods The flexible regions of secondary structure and the B cell epitopes of human heparanase amino acid sequence were predicted by DNAStar and Bcepred software. The multiple antigenic peptides (MAP) of the epitopes were synthesized in 8-branch form. Rabbits were immunized with the 8-branch MAPs mixed with a universal T-helper epitope human IL-1β peptide (VQGEESNDK, amino acid 163-171 ). The immunogenicity of the synthesized peptides was evaluated by ELISA, Western blot and immunohistochemistry. Results Amino acid 1 -15 ( MAP1), 279-293 (MAP2) and 175-189(MAP3) of large-subunit of human heparanase protein was predicted as the most potential epitopes of human heparanase protein. All the three synthesized MAPs induced high titer of antibodies. ELISA, Western blot and immunohistochemistry analysis showed all the three MAPs could produce high titer serum antibodies, antibodies induced by MAP1 and MAP2 had high specific binding activity , and MAP2 antibody showed the strongest binding activity with liver cancer tissues. Conclusion The large-subunit No. 1-15, 279-293 amino acid of human heparanase protein may be the B cell preponderant epitopes and the strongest immunogenicity may be No. 279-293 peptide, which provided a theoretic basis for the antibody and vaccine development of heparanase subunit peptide.

Objective To study the influence of transferring a dominant-negative Stat3 gene, Stat3?on colon cancer cells' proliferation and apoptosis in vitro. Methods Cell culture of human colon cancer cell line SW480 and transient transfection were used to evaluate the effect of transferring Stat3?to cancer cells. Cell proliferation, cell cycle and apoptosis were quantified by MTT and flow cytometry, respectively. The mRNA expression of Stat3's target gene cyclin D1 and bcl-xL was detected by reverse transcription polymerase chain reaction. Independent t tests were used for data statistics. Results 36 h after Stat3?plasmids transfection, proliferation of SW480 cells was significantly inhibited (t =5. 216,P = 0.006); cell proportion of G0/G1 phase increased from 40.37% to 67.25% and early apoptosis cells increased from 5. 34% to 24. 42% ; mRNA expression of cyclin Dl and bcl-xL declined significantly (t = 5.288,P=0.010;t=3.517,P=0.025). Conclusion Blocking Stat3 signaling pathway by transfection of Stat3?plasmid inhibits the proliferation and promotes apoptosis of colon cancer cells, which provides a experimental foundation of Stat3 targeted colon cancer gene therapy.
