Objective:To analyse the differences of related genes between serum alpha-fetoprotein (AFP) positive gastric cancer and AFP negative gastric cancer, and the relationship between related genes and prognosis of serum AFP positive gastric cancer.Methods:A total of 1 144 gastric cancer patients undergoing surgery at the 940th Hospital , Joint Logistic Support Force, People's Liberation Army from Jan 2013 to Dec 2018 were retrospectively analyzed. Of them, 47 cases were of AFP positive gastric cancer, and 47 serum AFP negative case were obtained by proper matching method.Results:Forty-seven patients with serum AFP positive gastric cancer, accounting for 4.1% of all gastric cancer patients during the same period. The prognosis of serum AFP negative gastric cancer is better than that of serum AFP positive gastric cancer. The 1-, 3- and 5-year cumulative survival rates were 95.6% vs. 63.8%, 48.9% vs. 23.4% and 26.7% vs. 14.9%, respectively. There were statistical differences in the immunohistochemistry of AFP, HER2, VEGF, GPC3, SALL4, P53 and Ki67 between the two groups ( χ2=67.758, P<0.001; χ2=4.004, P=0.044; χ2=19.299, P<0.001; χ2=5.232, P=0.022; χ2=6.359, P=0.012; χ2=6.224, P=0.013; χ2=5.232, P=0.022). The more co-positive expressions of AFP, GPC3, VEGF and SALL4, the more likely they were to affect pTNM stage, vascular invasion and liver metastasis ( χ2=5.328, P=0.021; P=0.013; χ2=5.887, P=0.015; χ2=3.923, P=0.048). Univariate and multivariate survival analysis of serum AFP positive gastric cancer showed:AFP, GPC3, VEGF and SALL4 were risk factors for AFP positive gastric cancer ( HR=3.700, P=0.036; HR=4.237, P=0.003; HR=3.916, P=0.004; HR=3.412, P=0.001). Conclusions:Serum AFP positive gastric cancer is a rare and highly invasive special type of gastric cancer. AFP, GPC3, VEGF and SALL4 are overexpressed in serum AFP positive gastric cancer, which is correlated with tumor stage, vascular invasion and liver metastasis. The final diagnosis of serum AFP positive gastric cancer still needs immunohistochemical examination. Preoperative serum AFP level is an important basis for AFP positive gastric cancer screening and AFP immunohistochemical examination.

Objective To investigate the expression of miR-143-3p and ATG2B in serum of patients with bladder cancer and their relationship with clinicopathology,prognosis and survival of patients.Methods Eighty-eight patients who underwent radical bladder cancer surgery in our hospital from January 2017 to January 2019 were regarded as the research group,and 80 volunteers who underwent physical examination in our hospital were included as the control group.Quantitative real-time PCR(qRT-PCR)method was performed to detect the levels of miR-143-3p and ATG2B;The predictive value of miR-143-3p and ATG2B for bladder cancer was evaluated by ROC curve.Draw survival curve using Kaplan Meier method;The prognostic factors of bladder cancer patients were analyzed by Cox regression.Results The expression level of miR-143-3p in the serum of bladder cancer patients was lower than that in the control group(0.68±0.12 vs.0.87±0.26),and the expression level of ATG2B was higher(1.02±0.30 vs.0.61±0.18)(P＜0.05);the expression level of miR-143-3p in serum of postoperative patients was higher than that before operation(0.77±0.23 vs.0.68±0.12),and the expression level of ATG2B was lower than that before operation(0.85±0.26 vs.1.02±0.30)(P＜0.05);The study group showed a negative correlation between miR-143-3p and ATG2B expression(r=-0.454,r=-0.407,P＜0.01);The AUC of miR-143-3p in the diagnosis of bladder cancer was 0.846(95％CI:0.783-0.897),the sensitivity and specificity were 79.55％and 78.75％respectively;The AUC of ATG2B in the diagnosis of bladder cancer was 0.883(95％CI:0.824-0.927),the sensitivity and specificity were 78.41％and 81.25％respectively;The AUC for the diagnosis of bladder cancer was 0.939(95％CI:0.891-0.970),the sensitivity and specificity were 87.50％and 88.75％,respectively.The 3-year survival rate of the miR-143-3p low expression group was 34.88％(15/43)lower than that of the high expression group 77.78％(35/45),and the 3-year survival rate of the ATG2B high expression group was 40.91％(18/44)lower than that of the low expression group 72.73％(32/44).The differences were statistically significant(Log rank x2=18.055,8.658,P=0.000,0.003).Lymph node metastasis,distant metastasis,tumor pathological grade,TNM stage,miR-143-3p,ATG2B are all factors influencing the survival of bladder cancer patients.Conclusion The serum expression of miR-143-3p in patients with bladder cancer is low,and the expression of ATG2B is high,and the expressions of the two are closely related to the clinicopathological characteristics and prognosis of patients with bladder cancer.
