Objective: To construct a nursing care service index system for postoperative ostomy patients with colorectal cancer based on Omaha system, which is used to guide nursing practice. Methods: Using the Omaha system as the conceptual framework, using literature search method, expert group discussion, Delphi expert correspondence method, screening indicators to establish a system of postoperative care services for patients with colorectal cancer. Results: The two rounds of expert letters asked that the effective recovery rate of the volume was 100%(28/28). The coefficient of expert authority of the two rounds of letters was 0.88 and 0.89 respectively, and the coordination coefficients of the expert opinions were 0.476 and 0.501 respectively. The finalized indicator system for care services includes 4 first-level indicators, 13 secondary indicators, and 61 third-level indicators. Conclusion The results of this study are scientific and reliable, and the formation of postoperative ostomy patients with colorectal cancerThe indicator system can provide a reference for clinical practice.

ObjectiveTo investigate the diagnosis and treatment of purple urine bag syndrome following transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).Methods Clinical data of 13 patients who developed purple urine bag syndrome out of 117 patients undergoing TACE for HCC in the Sixth Afifliated Hospital of Sun Yat-sen University between January 2012 and May 2014 were retrospectively studied. Among the 13 patients, 4 were males and 9 were females with the age ranging from 35 to 68 years old and the median of 53 years old. The tumor diameter was≤5 cm in 8 cases and was > 5 cm in 5 cases. The operative duration of TACE was≤30 min in 6 cases and was >30 min in 7 cases. The informed consents of all patients were obtained and the local ethical committee approval had been received. The diagnostic criteria was pink to purple urine in the urine bag after TACE and no blood urine detected by urine routine test.ResultsThe incidence of purple urine bag syndrome following TACE was 11.1% (13/117). After purple urine bag syndrome was confirmed, the patients were given the comprehensive therapy of urine acidification, rehydration, regular change of urinary catheter and urine bag, and gastrointestinal function improvement. No anti-infective therapy was given. The average indwelling time of urinary catheter was (12±3) d.ConclusionsIt is not a rare case for purple urine bag syndrome following TACE for HCC, thus it should be taken seriously. The treatment mainly includes urine acidiifcation, rehydration and gastrointestinal function improvement.

With the improvement of living standards,at least a quarter of the global population has non-alcoholic fatty liver disease(NAFLD),which is considered to be an important cause of the increased incidence of hepatocellular carcinoma(HCC)in recent years.Finding effective means for disease prevention and/or treatment largely relies on deep understanding of the mechanisms of NAFLD to HCC,which needs to con-struct the stable experimental models to simulate the entire process of disease progression in human NAFLD-HCC.This paper summarizes the animal models which are currently used to study NAFLD-HCC and their ad-vantages and disadvantages,in order to provide a basis for the selection of animal models and accelerate the transition from basic study to clinical study.

Objective To investigate the clinical efifcacy of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in treatment of liver metastasis of colon cancer. Methods A total of 68 patients with liver metastasis of colon cancer in the Sixth Affiliated Hospital of Sun Yat-sen University from June 2007 to May 2011 were enrolled in this prospective study. The informed consents of all patients were obtained and local ethical committee approval had been received. There were 43 males and 25 females with a mean age of (59±4) years old. The patients were divided into RFA group and Control group with 34 cases in each group according to random number table method. Patients in both groups underwent TACE ifrstly and patients in RFA group underwent RFA 3 weeks after TACE treatment. Cluster of differentiation (CD) 3+, CD4+, CD8+positive cell percentage and CD4+/CD8+ratio were deifned by flow cytometry before and after treatments in two groups. The tumor diameter after treatments and general efifcacy were observed. The patients were followed up and the tumor recurrence and survival of the patients were observed. The comparisons of tumor diameter and immune function between two groups were conducted using t test. The comparison of efifcacy between two groups was conducted using rank sum test. The survival analysis was conducted using Log-rank test and Z test. Results The CD4+, CD8+percentage and CD4+/CD8+ratio were (42±4)%, (13±3)%, 2.9±0.9 in RFA group after treatment and were (33±4)%, (17±3)%, 2.3±0.9 in Control group, where signiifcant differences were observed (t=5.483,-6.488, 9.321;P<0.05). The tumor diameter in RFA group after treatment [(0.9±0.1) cm] was significantly smaller than that in Control group [(1.9±0.2) cm] (t=-4.573, P<0.05). The total effective rate in RFA group was 62%(21/34) and was 35%(12/34) in Control group. The treatment efifcacy of RFA group was better than that of Control group (Z=4.769, P<0.05). The 2-, 3-year survival rates in RFA group (38.2%, 23.5%) were significantly higher than those in Control group (14.7%, 5.9%) (Z=4.836, 4.221; P<0.05). Conclusions TACE combined with RFA is a safe and effective regimen in treating liver metastasis of colon cancer. The efifcacy may be associated with the improvement of the body’s immune function.
