Objective To summarize the nursing experience of patients who had received licartinintravenously for preventing and treating tumor recurrence after liver transplantation in patients with primary hepatic carcinoma and provide the key points for clinical nurse staff. Methods The nursing insight of 7 patients who hadreceived licartin intravenously for preventing and treating tumor recurrence after liver transplantation in patients with primary hepatic carcinoma has been summarized. Results The key points were as follows ：taking psychologicalcare of patients，informing them the knowledge of radiation protection and engaging drug susceptibility tests，routineblood test，along with liver function test before operation；intensive observation，instant dealing with adverse reactions and discharge-related guidance should be given to patients post operation. Conclusion When using licartin forpreventing and treating tumor recurrence，clinical nurse staff should grasp the psychological quality and physical condition of patients on the basis of self-protection，observe the adverse reaction intensively and provide a qualitycare.

Objective To explore the role of non-invasive and invasive ventilation in cytomegalovirus （CMV） pneumonia induced severe acute respiratory distress syndrome（ARDS）after renaltransplantation. Methods A case of postoperative renal transplant CMV pneumonia and severe ARDS and literature were reviewed. Results More than 3 months after renal transplantation，the patient underwent fever andshort of breath. The chest radiographshowed bilateral pulmonary interstitial changes. His condition gradually worsenedwith obviously difficult breathing and the lowest oxygen partial pressure was 20 mmHg（1 mmHg ＝ 0.133 kPa） despite the conventional treatment. Noninvasive ventilation was given in time，and was changed to invasive ventilation according to the condition. Two weeks after the ventilation treatment，non-invasive ventilator was used again as the disease alleviated. The patient was treated for a total of 1 month before discharge. Conclusion With the timely and appropriate application of non-invasive and invasive ventilation in CMV pneumonia induced severe ARDS after renal transplantation，pulmonary function can be improved and the chance for the treatment of primary disease was won.
