Objective To assess the change of CEA in the peritoneal lavage fluit at pre-,post-laparoscopy-assisted radical gastrectomy, and after hyperthermic perfusion chemotherapy, and to investigate the influence of laparoscopy-assisted radical gastrectomy on drop off of cancer cells, the efficiency of hyperthermic perfusion chemotherapy. To investigate whether CEA in the peritoneal lavage fluit detected by flow cytometry (FCM) is an effective predictor of intraperitoneal free cancer cells and peritoneal metastasis. Methods Peritoneal washings of 40 patients with gastric carcinoma were collected to detect CEA using FCM. The peritoneal lavage cytology examinations ( PLC)were detected by H-E staining. Results Laparoscopic surgery in patients with gastric cancer,before resection of gastric cancer the peritoneal washing CEA positive rate 35. 0% (14/40) ,and after operation, the positive rate was 40. 0% ( 16/40) .which was not significantly higher than that before operation ( P > 0. 05 ). After intraperitoneal hyperthermic perfusion chemotherapy the CEA positive rate was 7. 5% (3/40) ,which was significantly lower than that pre-operation(P<0. 05). Before operation there were 4 cases of positive PLC in the peritoneal lavage fluid, 14 CEA-positive detected by flow cytometry, and there was significant difference ( P < 0. 05 ) . All PLC-positive cases were positive for CEA, whereas 10 PLC-negative cases showed CEA-positive. None of CEA-negative cases showed PLC-positive. Conclusions Laparoscopic radical gastrectomy does not increase the intra-abdominal gastric cancer cell shedding. Intraoperative hyperthermic perfusion chemotherapy is simple and feasible approach with high efficiency.Peritoneal washing CEA detected by flow cytometry is an effective index to predictor for intraperitoneal free cancer cells and prediction of peritoneal metastasis.

Objective To explore pre-hospital delay factor of coronary reperfusion therapy for ST-elevation acute myocardial infarction (STEAMI) patients presenting with non-chest pains. Methods A retrospective observation was conducted. The clinical data of STEAMI patients underwent emergency percutaneous coronary intervention (PCI) admitted to Luoyang Central Hospital Affiliated to Zhengzhou University from August 2013 to August 2015 were analyzed. The patients were divided into chest pain group and non-chest pain group according to the presence of chest pain or not. Clinical characteristics were compared between the two groups, and incidence of major adverse cardiac events (MACE), door-to-balloon time, door-to-electrocardiograms (ECG) time and ECG-to-balloon time were evaluated. Influencing factors of pre-hospital delay was analyzed by logistic multiple stepwise regression. Results A total of 259 patients with STEAMI were enrolled, including 154 patients with chest pain and 105 presented with non-chest pains. Compared with chest pain group, the patients in the non-chest pain group were older (years: 68.12±8.93 vs. 62.34±7.12, P < 0.05), less female (26.67% vs. 42.20%, P< 0.05), and had a higher past history of angina, stroke and heart failure (27.61% vs. 13.63%, 31.42% vs. 18.83%, 26.67% vs. 11.68%, respectively, all P < 0.05), and higher percentage of Killip ≥ Ⅲ patients (15.24% vs. 6.49%, P < 0.05), the lower ambulance use (26.67% vs. 44.81%, P < 0.01), longer hospitalization time (days: 12.50±2.89 vs. 9.50±2.67, P < 0.05), higher incidence of MACE (19.05% vs. 9.09%, P < 0.05), longer door-to-balloon time and door-to-ECG time (minutes: 159.01±51.21 vs. 115.31±36.74, 53.06±18.17 vs. 30.35±9.93, both P < 0.01). It was shown by logistic multivariate regression analysis that no-chest pain [odds ratio (OR) = 5.14, 95% confidence interval (95%CI) = 2.34-10.81, P < 0.001], age ≥ 65 years old (OR = 1.43, 95%CI = 0.93-2.99, P = 0.022), diabetes (OR = 1.57, 95%CI = 0.66-2.15, P = 0.015) and no-ambulance transport (OR = 1.55, 95%CI = 0.73-2.75, P < 0.001) were risks factors of coronary reperfusion delay ≥ 2 hours. Conclusions STEAMI patients presenting without chest pain showed higher incidences of MACE, longer time of ECG obtained and initial PCI time delay. Clinicians should try to reduce the delay time of the patients in order to improve patient survival rates.
