Objective To discuss the nursing care for patients with advanced hepatocellular carcinoma (HCC) who are receiving transcatheter arterial chemoembolization (TACE) combined with sorafenib. Methods A total of 23 consecutive patients with advanced HCC who met the inclusion criteria were enrolled in this study. TACE was carried out in all patients. Three-five days after TACE the patients started to orally take sorafenib. During the treatment course, the patients were kept under close observation for adverse reactions and complications. After leaving the hospital the patients were followed up by the extended care team members, and health education as well as appropriate nursing intervention was carried out. Results All patients with advanced HCC took sorafenib orally after TACE. The major adverse events and complications were gastrointestinal adverse reactions (n = 22) and transient liver dysfunction (n = 23). After leaving the hospital all the patients received regular follow- up examination and extended nursing care. Conclusion Usually, the incidence of adverse reactions is higher in patients with advanced HCC after TACE combined with sorafenib treatment. Careful in-hospital observation and extended out-hospital nursing can reduce the incidence of adverse reactions and thus improve the patient’s quality of life.

Objective: To observe the impact of vareniline tartrate on vascular endothelial function and inlfammatory factor releasing in acute coronary syndrome (ACS) patients with nicotine dependence after smoking withdrawal treatment.
Methods: We recruited the in-hospital ACS patients who were smoking ≥10 cigarettes/day for more than 10 years with at least moderate nicotine dependence, and randomly divided them into 2 groups: Varenicline group, the patients received oral medication for 2 weeks and Self withdrawal group, the patients without medication assistance.n=52 in each group. All patients received (10-30) min daily mission and consulting for quit smoking for 2 weeks. The basic information was recorded and blood levels of NO, IL-6 and ET-1 were compared before and after withdrawal treatment.
Results: Compared with they were before, after 2 weeks withdrawal treatment, in Varenicline group, blood levels of ET-1 decreased as (33.950 ± 1.439) ng/L vs (170.198 ± 12.602) ng/L and IL-6 decreased as (0.103 ± 0.020) ng/L vs (0.307 ± 0.051) ng/L; in Self withdrawal group, ET-1 decreased as (60.795 ±7 .036) ng/L vs (170.511 ± 12.374) ng/L, all P<0.05; while NO levels were similar,P>0.05. After treatment, ET-1 level in Varenicline group (33.950 ± 1.439) ng/L was lower than Self withdrawal group (60.795 ± 7.036) ng/L and IL-6 level in Varenicline group (0.103 ± 0.020) ng/L was also lower than Self withdrawal group (0.258 ± 0.042) ng/L, allP<0.05; while NO levels were similar between 2 groups,P>0.05.
Conclusion: Compared with self withdrawal, varenicline tartrate may effectively inhibit inlfammatory factor releasing in ACS patients with nicotine dependence, and therefore improve the vascular endothelial function.
