Objective To explore the nutritional status of radical gastrectomy patients during the late course of chemotherapy and its main influencing factors, providing reference for the development of targeted nursing intervention. Methods The Scored Patient-Generated Subjective Global Assessment, The Chemotherapy Side Effects of Patients with Gastric Cancer Questionnaire were used to collect clinical data that received complete chemotherapy after radical surgery from September 2014 to March 2016. Results A total of 103 cases finally involved in this study. The incidence of malnutrition in patients during pre-chemotherapy and late course of chemotherapy was 45.63%(47/103) and 73.79%(76/103) respectively, and there was significant difference (χ2=16.97, P<0.05). The nutritional assessment score, the hemoglobin levels and body mass index of patients pre-chemotherapy was (3.64±0.78) points, (124.11± 21.78) g/L, (21.29±2.77) kg/m2 , (8.07±3.75) points, (108.54±11.68) g/L, (20.29±2.68) kg/m2 late course of chemotherapy and there were significant differences(t =-11.74, 6.39, 2.63, all P<0.05). The symptom of depression was at a higher level 65.05%(67/103), patients with anorexia in late course of chemotherapy accounted as much as 75.73%(78/103). Logistic regression analysis showed that educational level, loss of appetite and parenteral nutrition were the main factors which influenced the nutritional status of patients during the late course of chemotherapy. Conclusions With the increase in the number of chemotherapy, the nutritional status of the patient is getting worse. The study suggests medical personnel should pay more attention to the patients with low educational level, give patients and their families targeted diet counseling, correct the mistaken conceptions thus enhance their understanding of dietary knowledge. Strengthening the management of complications during chemotherapy, reducing the adverse factors that affect the patient′s nutritional status to improve the nutritional status of patients.

Objective To investigate the nutritional status of patients with chemotherapy after radical gastrectomy and to provide dietary guidance and nutritional support for patients in time. Methods Patients who received chamotherary after radical gastrectomy inthe Gastrointestinal Surgery of the First Affiliated Hospital of Zhengzhou University from September 2014 to March 2016 were included in the study. The nutritional status was assessed by unified training investigators within 48 h after hospitalization. The questionnaires of Scored Patient-Generated Subjective Global Assessment (PG-SGA) and the Chemotherapy Side Effects of Patients with Gastric Cancer Questionnaire were used to investigatethe patients by trained investigators. Results The scores of the nutritional status of patients with different stages of chemotherapy were 6.107 ± 2.947, 6.505 ± 3.134, 8.068 ± 3.748, which was statistically significant (F=10.202, P<0.01). The incidence of anorexia was the highest rate of diet-related symptoms, the rate of early, mid-term and later chemotherapy rates were 34.95%(36/103), 56.31%(58/103), and 75.73%(78/103) respectively. Patients acquired the diet knowledge mainly from medical staff. The proportions of early, middle and later stages of chemotherapy were 92.23% (95/103), 79.61% (82/103), 75.73%(78/103). Conclusions With the increase of chemotherapy times, the nutritional status of patients with radical gastrectomy is getting worse. The results suggested that medical staff should provide an effective basis dietary guidance in time, improving the patients′nutritional status and clinical outcomes.

Objective: Due to the high cost and complicated imaging interpretation of intravascular ultrasound (IVUS), we conducted a comparative study between AngioLight system and IVUS measurement of coronary diameter to explore the safety and efifcacy of AngioLight performance in experiment pigs.
Methods: There were 3 reference target points established in left anterior descending (LAD), left circumlfex (LCX) and right coronary arteries (RCA) in 3 Chinese mini-pigs. Each coronary branch had①target point, ②proximal target point, which was (10-15) mm up to target point,③distaltarget point, which was (10-15) mm down to target point. The coronary diameters were measured and compared by both IVUS and AngioLight system. Upon stent implantation, the diameters were measured again by both IVUS and AngioLight system at distaltarget point, stent edge of distal target point and proximal target point, stent edge of proximal target point respectively. And results comparison between AngioLight and IVUS were also compared.
Results: In 25 measurements, neither adverse complication nor death were occurred during the study. There were no significant statistical differences between IVUS real-time max diameter and AngioLight catheter max diameter measurements (2.57 ± 0.54) mm vs (2.70 ± 0.49) mm,P=0.09, as well as between IVUS analyzed max diameter and AngioLight catheter max diameter (2.68 ± 0.6) mm vs (2.59 ± 0.42) mm,P=0.37. In addition, good correlations were observed (r= 0.73,P<0.001) and (r= 0.67,P=0.001) respectively.
Conclusion: Angio Light system has good safety and correlation with IVUS for quantitative measurement of coronary diameter in experimental pigs.
